Description

A color masterbatch sorting device

technical field

The utility model relates to production equipment for color masterbatches, in particular to a sorting device for color masterbatches.

Background technique

After the masterbatch strips are cut into masterbatches, due to the different sizes of the masterbatches, they need to be sorted to be suitable for different occasions. In the prior art, the screen of the color masterbatch sorting device is set horizontally. After the sorting of the color masterbatch is completed, air needs to be introduced into the box to blow out the color masterbatch located in the same cavity. The operation method is inconvenient. If the screen is set at an incline, the color masterbatch will easily flow from the upper inclined end of the screen to the lower inclined end of the screen during the vibration of the masterbatch sorting device. The screen does not screen the masterbatch sufficiently.

Contents of the invention

A screen for screening color masterbatches, wherein the screen located in the middle is in the opposite direction to the screen located on the upper and lower sides, and the apertures of the three screens change from top to bottom. Small, the lower end of each of the screens is provided with a discharge port; the four corners of the bottom of the box are connected with springs, and the bottom ends of each of the springs are connected to the base. The bottom of the box body is rotatably connected with a transmission shaft, the base is provided with a motor and a reduction box connected with the motor, and the lower end of the transmission shaft is connected with the upper end of the output shaft of the reduction box through an elastic coupling , the transmission shaft is fixedly sleeved with an eccentric block; each of the screen surfaces is provided with a number of downwardly recessed pits for delaying the flow of the masterbatch.

Specifically, the pits are arranged in several rows along the length direction of the screen, and the pits in two adjacent rows are distributed alternately.

Specifically, the inner contour of the pit is arc-shaped, and the ratio of the depth of the pit to the diameter of the pit is a, 0.2≤a≤0.4.

Specifically, the eccentric block has a guide groove, and a guide block cooperating with the guide groove is provided in the guide groove, and the guide block can slide along the guide groove to adjust the position. The output shaft is fixedly passed through the through hole.

Specifically, the eccentric block includes a pitch-adjusting screw, the pitch-adjusting screw is rotatably connected to the tail of the eccentric block, and the head section of the pitch-adjusting screw is threadedly connected to the guide block.

The beneficial effects of the utility model are:

During the vibration of the masterbatch along the screen, part of the masterbatch will enter the pit. The color masterbatch entering the pit will be restricted by the concavity contour of the pit to slow down the flow rate, so it will not flow from the higher end of the screen to its lower end at once, so the masterbatch can contact the screen more fully The mesh allows the screen to more fully screen the masterbatch.

detailed description

The specific embodiment of the utility model will be further described below in conjunction with the accompanying drawings.

As shown in FIG. 1 , the color masterbatch sorting device provided in this embodiment includes a base 4 and a square box 1 , and a feeding port 11 is provided on the top of the box 1 . Inside the box 1 there are three screens 2 inclined from top to bottom for screening color masterbatches, wherein the screen 2 in the middle is in the opposite direction to the screens 2 on the upper and lower sides. The apertures of the sieve holes of the three sieves 2 become smaller successively from top to bottom. A discharge port 12 is provided at the lower end of each screen 2 . The four corners of the bottom of the box body 1 are all connected with springs 3 , and the bottom ends of each spring 3 are connected with the base 4 . A transmission shaft 8 is rotatably connected to the bottom of the box body 1 , and the base 4 is provided with a motor 5 and a reduction box 6 connected with the motor 5 . The lower end of the transmission shaft 8 is connected to the upper end of the output shaft of the reduction box 6 through an elastic coupling 9 , and the transmission shaft 8 is fixedly sleeved with an eccentric block 7 . The surface of each screen 2 is provided with a number of pits 21 sunken downwards for delaying the flow of the color masterbatch.

The working process of the color masterbatch sorting device provided by the present embodiment is:

First put the color masterbatch into the box body 1 through the feed port 11, then turn on the motor 5, and the motor 5 drives the output shaft 61 of the reduction box 6 to rotate. Since transmission shaft 8 is connected with the output shaft of reduction box 6 through elastic coupling 9, motor 5 drives the output shaft of reduction box 6 to rotate, and the output shaft of reduction box 6 drives transmission shaft 8 to rotate through elastic coupling 9. Since the transmission shaft 8 is fixedly sheathed with the eccentric block 7 , the transmission shaft 8 swings away from the axis of the transmission shaft 8 during rotation, that is, the axis of the transmission shaft 8 is not collinear with the axis of the output shaft of the reduction box 6 . Therefore, the swing of the transmission shaft 8 drives the box body 1 to vibrate, thereby vibrating and screening the color masterbatch on the surface of the top screen 2 . During the vibration of the color masterbatch along the screen 2 , part of the color masterbatch will enter the pit 21 . The color masterbatch that enters the pit 21 will be restricted by the concave contour of the pit 21 to slow down the flow rate, so it will not flow from the higher end of the screen 2 to its lower end at once, so the masterbatch can be more fully Contact the sieve 2 so that the sieve 2 can more fully screen the color masterbatch. After vibrating and screening for a period of time, the color masterbatch remaining on the screen cloth 2 flows to its lower end position and is discharged from the discharge port 12. The color masterbatch passing through this layer of screen 2 enters the next layer of screen 2, and the apertures of the three screens 2 become smaller from top to bottom, so that the color masterbatch can be divided into coarse grains (left in the first First layer of sieve 2), medium particles (stay on the second layer of sieve 2), fine particles (stay on the third layer of sieve 2) and powder (fall to the bottom of the box 1). Finally, the powder particles are discharged from the discharge port (not shown) at the bottom of the box body 1 .

Specifically, the pits 21 are arranged in several rows along the length direction of the screen 2, and the pits 21 of two adjacent rows are distributed alternately, so that the color masterbatch can more fully contact the pits 21, so that the screen 2 can more fully Screen the masterbatch.

Specifically, the inner wall of the pit 21 is arc-shaped, and the ratio of the depth of the pit 21 to the diameter of the pit 21 is a, a=0.3, so that the contact area between the pit 21 and the color masterbatch increases without As for the greater resistance to the flow of masterbatch.

Specifically, the eccentric block 7 has a guide groove 71, and a guide block 72 cooperating with the guide groove 71 is arranged in the guide groove 71. The guide block 72 can slide along the guide groove 71 to adjust the position. The guide block 72 is provided with a through hole 721, and the output The shaft 61 (see FIG. 1 ) is fixedly passed through the through hole 721 . By adjusting the position of the guide block 72, the distance between the center of gravity of the eccentric block 7 and the output shaft 61 can be adjusted, thereby adjusting the amplitude of the box 1 to adapt to the screening of different amounts of masterbatches.

The eccentric block 7 includes a distance-adjusting screw rod 73, which is rotatably connected to the tail of the eccentric block 7, and the head section of the distance-adjusting screw rod 73 is threadedly connected with the guide block 72. Rotating the distance-adjusting screw rod 73 can easily adjust the eccentric block 7 The distance between the center of gravity and the output shaft 61, so that the vibration amplitude of the box body 1 can be adjusted conveniently.

What is disclosed above is only the preferred embodiment of the present utility model, and of course the scope of rights of the present utility model cannot be limited with this. Therefore, the equivalent changes made according to the patent scope of the utility model still belong to the scope covered by the utility model .
