Description

Spray system with oblique guiding and supporting plate mechanism

The present invention relates to a blasting system with an obliquely guiding and supporting plate mechanism, and in particular to a blasting system capable of continuously blasting the plate to improve the fatigue strength of the plate and the hardness of the workpiece surface, thereby increasing the service life.

For the surface treatment of metal workpieces, the applicant proposed a blasting machine that can provide the advantages of combining sandblasting and shot peening. Its impeller equipment can spray blasting particles at high speed. The particle size of the blasting particles can be between the sand material of sandblasting and the steel shot of shot peening. It can not only provide a cleaning effect and improve the surface roughness, but also further improve the fatigue strength of the workpiece and the hardness of the workpiece surface, thereby enhancing the service life. It has been approved as TW I709460 "blasting machine and its impeller equipment".

However, when the blasting machine is performing blasting of the particles onto the surface of the plate, since the plate is transported in a horizontal state, the blasting particles are easily adsorbed onto the surface of the plate, which will cause the plate to absorb sand. Therefore, a complex sand removal mechanism and sand removal operation must be set up, resulting in an increase in cost.

The technical problem to be solved by the present invention is to provide a spray system with an oblique guiding and supporting plate mechanism to address the deficiencies of the prior art, which can effectively solve the problem of sand absorption without the need to set up a complex sand removal mechanism and can simplify the sand removal operation to achieve the effect of reducing costs.

In order to solve the above technical problems, the present invention provides a blasting system with an oblique guiding and supporting plate mechanism, comprising: an unwinder, which can be used to place plates, and the plates are transported along a conveying path; a first oblique clamping mechanism, which is arranged on the conveying path, and the first oblique clamping mechanism is located at a downstream position of the unwinder, and the first oblique clamping mechanism can bend the plates into an inclined state; a blasting machine assembly, which is arranged on the conveying path, and the blasting machine assembly is located at a downstream position of the first oblique clamping mechanism, and the blasting machine assembly includes a plurality of blasting machines, each of which has a chamber and at least two centrifugal impellers, and the at least two centrifugal impellers are respectively arranged On the two opposite sides of the chamber, the spray machine assembly can continuously spray the plate, and the at least two centrifugal impellers each have a sand outlet surface, and the sand outlet surface is inclined corresponding to the plate; a second oblique clamping mechanism is arranged on the conveying path, the second oblique clamping mechanism is located at the downstream position of the spray machine assembly, and the second oblique clamping mechanism can receive the plate output by the spray machine assembly; a guiding mechanism is arranged on the conveying path, the guiding mechanism is located at the downstream position of the second oblique clamping mechanism, and the plate can be corrected by the guiding mechanism to be horizontal; and a winding machine is located at the downstream position of the guiding mechanism and can be used to wind up the plate.

The beneficial effect of the present invention is that the blasting system with an oblique guiding and supporting plate mechanism provided by the present invention can convey the plate at an inclination, and the sand discharge surface of the centrifugal impeller is inclined corresponding to the plate. When the blasting machine sprays the blasting particles to hit the surface of the plate, the blasting particles can automatically fall by gravity, and the blasting particles will not be adsorbed on the surface of the plate, and will not cause the problem of the plate absorbing sand. Therefore, the sand removal mechanism and sand removal operation can be simplified, and the cost can be reduced.

In this embodiment, two centrifugal impellers 412 are respectively arranged at the two sides of the plate 100, that is, each jetting machine 41 is provided with four centrifugal impellers 412 in total, and the four centrifugal impellers 412 are arranged at the two sides of the plate 100 in pairs, and the centrifugal impellers 412 at the two sides of the plate 100 are arranged staggered. The impinging particles can be sprayed and hit the surface of the plate 100 through the centrifugal impellers 412. The centrifugal impellers 412 are arranged on both sides of the plate 100 to symmetrically spray the upper and lower surfaces of the plate 100 to offset the upper stress and lower stress formed by the spraying, keep the plate 100 flat, and avoid local unevenness caused by different tensions on the surface.

In this embodiment, at least one partition curtain 418 (as shown in FIG. 5 ) is disposed at each of the two ends (inlet end and outlet end) of each chamber 411 .

In this embodiment, a detection area 419 (as shown in FIG. 1 and FIG. 5 ) may be provided at one end (exit end) of each of the spraying machines 41. At least one image capturing device 8 may be provided in the detection area 419. The image capturing device 8 may be, for example, a camera lens. The image capturing device 8 may be used to capture the surface image of the plate 100, that is, the image after passing through the spraying machine 41. Preferably, at least two image capturing devices 8 may be provided in each of the detection areas 419, which may be used to capture the images of the upper surface and the lower surface of the plate 100, respectively. Specifically, the surface image of the plate 100 can be captured as a photo, which includes the entire width of the plate 100 and reaches a predetermined length, which is sufficient to determine the processing status of the surface of the plate 100 after the blasting machine 41. This predetermined length can be adjusted according to the size of the plate 100. Alternatively, the surface image of the plate 100 can also include multiple photos, and according to the width of the plate 100, multiple ranges of the same unit area are obtained between the two side edges, such as multiple rectangles or multiple circles, and sampled for representative inspection. However, the present invention is not limited to this.

The image capture devices 8 are electrically connected to an image recognition control module 9 (as shown in FIG. 1 ). The image recognition control module 9 can be used to receive the image signal of the image capture device 8 and compare it with a reference surface image of the same blasting program preset in the database, thereby controlling the sand output of the blasting machine 41. In this embodiment, the image capture device 8 can be electrically connected to the image recognition control module 9 in a wired or wireless manner. The image recognition control module 9 includes but is not limited to an artificial intelligence Internet of Things (AIOT). For example, it can also be a computer. The image recognition control module 9 has a receiving unit, a memory device, a central processing unit, and an output unit. The above-mentioned database may be located in a computer memory device, such as a hard disk, wherein the reference surface image is stored in the database and has been manually screened to be sufficient to represent the surface treatment that has passed the above-mentioned stage, that is, the surface image of the qualified result of the blasting machine 41.

The processing indicators of the surface image of the above-mentioned blasting of the present invention may include the functions of sand blasting and shot peening. For example, the surface of the object is cleaned, the surface roughness is improved, the properties of the workpiece are strengthened, the corrosion at the crack tip is reduced, and the microstructure of countless circular pits is generated on the surface of the plate 100. Therefore, representative indicators include, for example, the roughness of the surface of the plate 100 and the total area of rust spots. Generally speaking, after the workpiece is processed, the roughness of its surface needs to reach a predetermined flatness and remove the oxide scale. In this embodiment, an image capture device 8 and an image recognition control module 9 are set downstream of the blasting machine 41, which can more accurately control the sand blasting amount and blasting intensity to achieve a more environmentally friendly effect.

The second diagonal clamping mechanism 5 can be used to receive the plate 100 output by the spraying machine assembly 4, so that the plate 100 can pass through the second diagonal clamping mechanism 5 and the guiding mechanism 6 and then be conveyed to the winder 7. The structure of the second oblique clamping mechanism 5 is not limited. In this embodiment, the structure of the second oblique clamping mechanism 5 is the same as that of the first oblique clamping mechanism 3. The second oblique clamping mechanism 5 at least includes a second outer frame 51 and two second clamping rollers 52 (as shown in Figure 3). The two second clamping rollers 52 are rotatably arranged on the second outer frame 51. The two second clamping rollers 52 are parallel to each other and the two second clamping rollers 52 are inclined. The two second clamping rollers 52 can be inclined at a predetermined angle according to the needs of the plate 100. The plate 100 passes between the two second clamping rollers 52 to stably maintain the inclined state of the plate 100 between the first oblique clamping mechanism 3 and the second oblique clamping mechanism 5.

The guiding mechanism 6 is arranged on the conveying path A, and is located downstream of the second diagonal clamping mechanism 5. The winder 7 is located downstream of the guiding mechanism 6. The guiding mechanism 6 can be used to receive the plate 100 output by the second diagonal clamping mechanism 5, so that the plate 100 can be corrected by the guiding mechanism 6 to be horizontal. The structure of the guiding mechanism 6 is not limited. In this embodiment, the guiding mechanism 6 at least includes a bracket 61 and two guiding rollers 62 (as shown in FIG. 1 ). The two guiding rollers 62 are rotatably disposed on the bracket 61. The two guiding rollers 62 are horizontally disposed and parallel to each other.
