Please refer to FIG. 1 , the packaging paint lifting pipe 10 includes an oil inlet pipe 100 and an air extraction part 200 , and the oil inlet pipe 100 and the air extraction part 200 are connected. The oil inlet pipe 100 is used for connecting the paint pipe 90 . The paint pipeline 90 is connected to an external oil delivery pump, and the oil delivery pump delivers paint to the paint pipeline when the oil delivery pump works. The air extractor 200 is used for extracting paint volatilization gas when filling the paint bucket with paint, so as to discharge the paint volatilization gas to the outside.

Please refer to FIG. 2 and FIG. 3 , the suction element 200 includes a disc body 210 and an air outlet pipe 220 , the disc body 210 has a cavity 230 , and the air outlet pipe 220 is connected to the disc body 210 . The air outlet pipe 220 communicates with the cavity 230 . The air outlet pipe 220 is used for connecting an external exhaust fan. For example, the suction fan communicates with the air outlet pipe 220 through an air duct. In this way, when the exhaust fan works, the air outlet pipe 220 is exhausted, so that the cavity 230 communicated with the air outlet pipe 220 generates air negative pressure.

The disc body 210 defines an air intake slot 211 and a mounting hole 212 . The air intake groove 211 communicates with the installation hole 212 . The oil inlet pipe 100 passes through the installation hole 212 and connects with the disc body 210 . The end of the oil inlet pipe 100 is located in the air intake groove 211 . For example, the surface of the disc body facing away from the oil inlet pipe is provided with several air inlet holes communicating with the cavity, and the several air inlet holes are distributed around the opening of the air inlet groove. A plurality of air intake holes 213 are opened on the surface of the disc body 210 , and the plurality of air intake holes 213 communicate with the cavity 230 .

Negative pressure, when the paint pipe 90 feeds paint into the oil inlet pipe 100, the paint bucket 80 is filled with paint through the oil inlet pipe 100, and the irritating gas overflowing from the opening 81 of the paint bucket 80 will be released from the tray body under the action of atmospheric pressure. The air inlet 213 on the surface of the 210 enters the cavity 230 of the disc body 210, and then is discharged to the outside through the outlet pipe 220, which greatly reduces the content of volatile gases in paint in the paint filling place, and avoids the harm of volatile gases in paint to the human body , to create an environmentally friendly and hygienic environment for filling operators.

For example, the installation hole 212 is a circular structure, for example, the oil inlet pipe 100 is a cylinder. The inner diameter of the installation hole 212 is slightly smaller than the outer diameter of the oil inlet pipe 100 , so that the oil inlet pipe 100 and the disc body 210 have an interference fit, so that the oil inlet pipe 100 and the disc body 210 can be stably connected. As another example, the outer diameter of the oil inlet pipe 100 is equal to the inner diameter of the mounting hole 212, the inner diameter of the air inlet groove 211 is greater than the inner diameter of the installation hole 212, and the oil inlet pipe 100 is integrally formed with the disc body 210, so that the oil inlet pipe 100 and the disc body 210 can also be formed in one piece.

This facilitates the transfer of paint.

Please refer to FIG. 1 and FIG. 3 together. In one embodiment, the packaging paint lifting pipe also includes a fastener 300. The oil inlet pipe 100 is provided with a fixing screw hole 101 penetrating the pipe wall, and the fastener 300 is penetrated through the fixing screw hole 101. It is connected with the oil inlet pipe 100 , and the end of the fastener 300 abuts against the paint pipe 90 . In this way, the paint pipe 90 can be fixed in the oil inlet pipe 100 by the fastener 300, so as to avoid peeling off between the paint pipe 90 and the oil inlet pipe 100 during the paint filling process, and improve the stability of the paint filling.

Further, the fastener 300 includes a fixing screw 310 , and the fixing screw 310 is screwed into the fixing screw hole 101 to abut against the paint pipe 90 . As shown in FIG. 2 , further, a stop block 102 is provided on the inner wall of the oil inlet pipe 100 , and the stop block 102 is used to abut against the paint pipe 90 inserted into the oil inlet pipe 100 . In this way, the paint pipe 90 can be fixed in the oil inlet pipe 100 better and more stably.

Please refer to FIG. 2 and FIG. 4 together. In order to better fill paint into the paint bucket 80 , for example, the end of the oil inlet pipe 100 protrudes from the notch of the air inlet groove 211 , as shown by the dotted arrow in FIG. 2 . Like this, the oil inlet pipe 100 that protrudes from the notch of the air inlet groove 211 can stretch into the opening 81 of the paint bucket 80 slightly when the paint is filled, so that the paint that comes out from the end of the oil inlet pipe 100 is better packed into the paint bucket 80 without sputtering outward.

For example, the surface of the disc body 210 facing away from the oil inlet pipe 100 is recessed to form an air inlet groove 211 . For example, the air intake slot 211 is opened in the central area of the disc body 210 . In this way, the structure of the pumping part 200 can be made compact and orderly, which is convenient for the filling operation.

For the convenience of cleaning the disc body, for example, the disc body includes a hood and an annular box, the hood is a circular plate, the annular box is a ring with one side open, and the evacuation The cover is arranged on the annular box body, and the exhaust cover is detachably connected with the annular box body. The cavity is formed between the exhaust hood and the annular box body. The installation hole is opened in the exhaust hood, for example, the installation hole is opened in the middle area of the exhaust hood. A plurality of air inlets are opened at the bottom of the annular box body. For example, the exhaust hood is provided with an exhaust hole facing away from the annular box body, and the outlet pipe is passed through the exhaust hole and connected with the exhaust hood, for example, the outlet pipe is connected to the exhaust hood. The air cover is integrally formed. Since paint volatile gas and air dust can be adsorbed on the disc body, the air intake hole will be blocked after filling the paint for a period of time, so the disc body needs to be cleaned regularly. In this way, the exhaust hood and the annular box body can be disassembled from the oil inlet pipe during cleaning, and then the exhaust hood and the annular box body can be separated for cleaning respectively. Cleaning with water, etc. is convenient and quick.

Please refer to FIG. 3 and FIG. 4 , in order to expedite the extraction of paint volatile gas, for example, a number of gas outlets 214 communicated with the cavity 230 are provided on the side wall of the air inlet groove 211 . For example, several air outlets 214 are evenly distributed on the sidewall of the air inlet groove 211 . For example, the air outlet 214 is an oval structure. Like this, because the inner diameter of air inlet groove 211 is greater than the outer diameter of oil inlet pipe 100, paint volatile gas fills up inlet groove 211 when overflowing from opening 81 of paint 80, at this moment, can accelerate the discharge of paint volatile gas by air outlet 214 Discharge, improve the efficiency of paint volatile gas discharge.

Please refer to FIG. 5 , FIG. 6 and FIG. 7 together. In one embodiment, the packaging paint lifting tube further includes a fuel-saving switch 400 , which is connected to the oil inlet pipe 100 . The oil inlet pipe 100 is provided with an adjustment hole 104 penetrating through the pipe wall. The fuel-saving switch 400 includes a fastener 300 , a rotating disc 410 , a switch valve 420 and a connecting rod 430 . The fastener 300 passes through the fixing screw hole 101 and connects with the oil inlet pipe 100 .

The rotating disc 410 is elastically and rotationally connected with the fastener 300 . The switching valve 420 includes an oil baffle 421 and a rotating shaft 422 , the oil baffle 421 is connected to the rotating shaft 422 , and the oil baffle 421 is located in the oil inlet pipe 100 . The rotating shaft 422 passes through the adjusting hole 104 and is rotatably connected with the oil inlet pipe 100 . One end of the connecting rod 430 is connected to the rotating disk 410 , and the other end of the connecting rod 430 is connected to the rotating shaft 422 .

Like this, can adjust the position of oil baffle plate 421 in oil inlet pipe 100 by rotating disk 410, when paint pipeline passes into paint into oil inlet pipe 100, adjust oil baffle plate 421 and make it in the vertical position of oil inlet pipe 100 so that Paint can pass through oil inlet pipe 100 smoothly; Fall to the external pollution paint bucket, and along with the arrival of the next empty paint bucket, adjust the oil baffle 421 to make it in the vertical position in the oil inlet pipe 100, the paint on the rear oil baffle 421 can drop to the empty In the paint bucket, save paint and avoid waste.

In order to facilitate the adjustment of the position of the oil baffle 421 on the oil inlet pipe 100, as shown in Figure 6, Figure 7 and Figure 8, for example, the fastener 300 includes a fixed screw 310, a fixed block 320 and an elastic member 330, and the fixed screw 310 is screwed into The fixing screw hole 101 is connected with the oil inlet pipe 100 . The rotating disc 410 is rotatably sleeved on the fixing screw 310 . The end of the fixing screw 310 is connected to the fixing block 320 , one end of the elastic member 330 is connected to the fixing block 320 , and the other end of the elastic member 330 is connected to the rotating disk 410 . In this way, by rotating the rotating disk 410, the connecting rod 430 is driven to move, thereby causing the rotating shaft 422 to rotate, and the rotating shaft 422 will drive the oil baffle 421 to rotate, thereby adjusting the position of the oil baffle 421 on the oil inlet pipe 100. At the same time, when the user releases the After rotating the disk 410, under the action of the elastic member 330, the rotating disk 410 rotates in reverse and returns to its original position. During the process, the connecting rod 430 will be driven to move, and the oil baffle 421 will be driven to rotate in reverse, so that the oil baffle 421 will recover. Original position, so that the position of the oil baffle 421 in the oil inlet pipe 100 can be adjusted every time, and the oil baffle 421 can automatically return to the original position, which can facilitate the filling of the paint, such as the elastic member 330 before filling the paint. In the relaxed state, the oil baffle 421 is in a vertical position in the oil inlet pipe 100, that is, it does not block the output of paint from the oil inlet pipe 100; after rotating the rotating disc 410, before letting go, the oil baffle 421 is in a horizontal position in the oil inlet pipe 100 At this time, the oil baffle plate 421 can receive and block the remaining paint in the paint pipeline to continue to drip out from the oil inlet pipe 100. This state corresponds to after a paint bucket is filled and before the next paint bucket arrives; when the next paint bucket arrives Afterwards, unclamp the rotating disc 410, and the oil baffle plate 421 returns to the vertical position in the oil inlet pipe 100, to continue filling paint, and so circulates. This way can facilitate the adjustment of the position of the oil baffle plate 421 on the oil inlet pipe 100, and realize high-efficiency paint filling.

At this time, the extension direction of the oil baffle is perpendicular to the extension direction of the oil inlet pipe, that is, the oil baffle surface of the oil baffle is perpendicular to the extension direction of the oil baffle, so that The paint is blocked by the oil baffle plate, so that the remaining paint in the paint pipeline can be connected, and the paint is prevented from dripping from the oil inlet pipe 100 to the external pollution paint bucket, and the oil baffle is adjusted with the arrival of the next empty paint bucket Plate 421 makes its vertical position in the oil inlet pipe 100, and the paint on the oil baffle plate 421 can drop into the empty paint bucket, saving paint and avoiding waste.

For example, there are multiple elastic members 330 , and each elastic member 330 is connected to the fixed block 320 and the rotating disk 410 respectively. In this embodiment, the number of elastic members 330 is four, and the four elastic members 330 are distributed in a rectangular shape. For example, the elastic member 330 is a spring, and for another example, the elastic member 330 is a compression spring, and for another example, the elastic member 330 is a torsion spring. In this way, the position of the oil baffle plate 421 on the oil inlet pipe 100 can be better elastically adjusted.

In order to better prevent residual paint from dripping, for example, the oil baffle 421 is a cylindrical plate-shaped structure. For example, the outer diameter of the oil baffle 421 is equal to the inner diameter of the oil inlet pipe 100 . For example, the oil baffle plate 421 defines an oil receiving groove. For example, the oil receiving groove is a groove formed by recessing the oil baffle plate 421 . In this way, better prevention of residual paint dripping can be achieved.

In order to make the rotation of the oil baffle 421 more stable, as shown in FIG. 6 , for example, the oil inlet pipe 100 is provided with a rotating hole 105 penetrating through the pipe wall, and the rotating shaft 422 passes through the adjusting hole 104 and the rotating hole 105 in turn. For example, the rotating hole 105 is opposite to the regulating hole 104 . For example, the outer diameter of the rotating shaft 422 is equal to the inner diameter of the rotating hole 105 . For example, the inner diameter of the rotating hole 105 is equal to the inner diameter of the adjusting hole 104 . The oil baffle 421 is connected to the rotating shaft 422 , for example, the oil baffle 421 is located above the rotating shaft 422 . In this way, the rotating shaft 422 abuts against the two pipe walls of the oil inlet pipe 100 respectively through the adjusting hole 104 and the rotating hole 105, which increases the pressure that can be tolerated. When the oil baffle plate 421 receives more paint, the rotating shaft 422 can still maintain The stable state does not fall off, and the rotation process is more stable, so that the process of filling paint is efficient and interference-free.

Please refer to FIGS. 5 to 9 together. In order to make the oil baffle plate 421 maintain a vertical position in the oil inlet pipe 100 or a horizontal position in the oil inlet pipe 100 during one rotation, for example, the inner side of the oil inlet pipe 100 The pipe wall is provided with a first limiting block 110 and a second limiting block 120, and the first limiting block 110 and the second limiting block 120 are respectively located at different positions. For example, the first limiting block 110 and the second limiting block 120 are cylindrical structures. For example, the first limit block 110 is adjacent to the rotating hole 105, and for another example, the first limit block 110 is located above the oil baffle plate 421 in the vertical direction, and on the vertical plane, the first limit block 110 and the rotating shaft The distance between 422 is equal to the thickness of the oil baffle plate 421, so that under the limit blocking effect of the first stop block 110, the oil baffle plate 421 can be kept in a vertical position in the oil inlet pipe 100 during one rotation; Ground, the second limit block 120 is set away from the rotating shaft 422, the second limit block 120 is located above the oil baffle plate 421 in the vertical direction, and on the horizontal plane, the distance between the second limit block 120 and the rotating shaft 422 The distance is equal to the thickness of the oil baffle 421 , so that under the limiting and blocking action of the second limiting block 120 , the oil baffle 421 can maintain a horizontal position in the oil inlet pipe 100 during one rotation. In this way, the remaining paint in the paint pipeline can be better realized, and the effect of paint dripping from the oil inlet pipe 100 to the outside to pollute the paint bucket can be avoided.
