This technology is widely used in the production processes of various metal parts and products, including fields such as automobiles, household appliances, construction, and mechanical equipment.

[0003] In the prior art solution, a Chinese patent with the authorization announcement number CN220239038U discloses an adjustable metal part spraying device. The motor is supported and connected to the vertical plate through a support plate. Transmission wheels are fixedly sleeved on the outer surfaces of the two rotating shafts, and a conveyor belt is commonly driven and connected to the outer surfaces of the two transmission wheels. A paint box connected to the bottom plate is arranged outside the conveyor belt, and conveying ports adapted to the conveyor belt are correspondingly opened on the left and right sides of the paint box. A spraying assembly is arranged inside the paint box. When in use, the metal parts to be sprayed are sent into the paint box through the conveyor belt, and then the spraying assembly sprays the metal parts on the conveyor belt.

[0004] The deficiencies of the above prior art solution are as follows: Since the spraying assembly will release paint mist or liquid paint during the spraying process, these paints may splash onto the conveyor belt due to insufficient spraying accuracy or excessive spraying pressure. Over time, these paints accumulated on the conveyor belt will gradually solidify, forming a paint film that is difficult to remove. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a metal part spraying device to solve the technical problem that paints will accumulate on the conveyor belt in the prior art.

[0006] The technical problem to be solved by the utility model can be achieved through the following technical solutions: A metal part spraying device includes a fixed bracket, a transportation mechanism, a spraying mechanism, and a cleaning mechanism. The transportation mechanism includes a driving roller, a driven roller, a driving member, and a conveyor belt. The driving roller and the driven roller are respectively rotatably arranged at both ends of the fixed bracket. The conveyor belt is wound around the outside of the driving roller and the driven roller. The driving member is used to drive the rotation of the driving roller. The spraying mechanism includes a paint box, a storage tank, a spray head, and a liquid pump. The paint box is fixedly installed on the fixed bracket, and conveying ports adapted to the conveyor belt are correspondingly opened on both the left and right sides of the paint box. The storage tank is fixedly installed on the top of the paint box. A plurality of groups of spray heads are provided, and all the spray heads are arranged in a matrix in the paint box. The input end of the liquid pump is communicated with the storage tank, and the output end of the liquid pump is communicated with all the spray heads. The cleaning mechanism includes a scraping component and a material receiving frame. The scraping component and the material receiving frame are arranged on the fixed bracket, and the scraping component is located at one end of the conveyor belt, and the material receiving frame is located below the scraping component.

[0007] As a further scheme of the utility model: The scraping component includes a fixed seat, a scraping plate, a limiting rod, and a return spring. A sliding groove is provided on the fixed seat. The limiting rod is slidably arranged in the sliding groove. The return spring is arranged between the sliding groove and the limiting rod. The scraping plate is provided with a limiting groove adapted to the limiting rod.

[0008] As a further scheme of the utility model: The limiting rod is in sliding contact and cooperation with the limiting groove. An inverted buckle is provided at one end of the limiting rod. The limiting groove is a through groove. When the limiting rod is completely inserted into the limiting groove, the inverted buckle buckles the notch of the limiting groove.

[0009] As a further scheme of the utility model: The spraying mechanism further includes two groups of isolation curtains, which are fixedly installed at the corresponding conveying ports.

[0010] As a further scheme of the utility model: The spraying mechanism further includes a suction pump. The input end of the suction pump is communicated with the material receiving frame, and the output end of the suction pump is communicated with the storage tank.

[0011] As a further scheme of the utility model: A filter screen is provided in the material receiving frame, and the filter screen is located at the input end of the suction pump.

[0012] As a further scheme of the utility model: The cleaning mechanism further includes two groups of baffle plates, which are fixedly installed at both ends of the scraping component.

[0013] The beneficial effects of the utility model compared with the prior art are:

[0014] 1. Through the scraping component in the cleaning mechanism, it can closely adhere to the surface of the conveyor belt and effectively scrape off the paint accumulated on the conveyor belt. This avoids the paint from gradually solidifying into a hard-to-remove paint film after staying on the conveyor belt for a long time. At the same time, it reduces the production interruption time caused by shutdown for cleaning and improves production efficiency. In addition, the paint collected in the material receiving frame can be reused after appropriate treatment, which reduces paint waste and production costs.

[0015] 2. A filter screen is fixedly installed in the material receiving frame. During the process of the paint being scraped off by the scraping component and falling into the material receiving frame, some impurities may be brought in, such as metal chips, dust, etc. Through the filtration of the filter screen, the impurities in the paint are removed, thus improving the purity and quality of the paint.

[0016] 3. As the scraper in the scraping component is used for a long time, the surface of the scraper will be worn and corroded, resulting in a decrease in the paint scraping efficiency. By means of extrusion and buckling, the limiting rod slides into the chute, thus disengaging from the limiting groove of the scraper, realizing quick replacement of the scraper, which can reduce the shutdown time required for replacing the scraper and thus improve work efficiency.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] like Figures 1 to 7 As shown, a metal parts spraying device comprises a fixed bracket 1, a transport mechanism 2, a spraying mechanism 3 and a cleaning mechanism 4, wherein the transport mechanism 2 comprises an active roller 21, a driven roller 22, a driving member 23 and a conveyor belt 24, wherein the active roller 21 and the driven roller 22 are respectively rotatably arranged at two ends of the fixed bracket 1, and the conveyor belt 24 is wound between the active roller 21 and the driven roller 22, and the driving member 23 is used to drive the rotation of the active roller 21, and the driving member 23 is a rotating motor or other element that can drive the active roller 21 to rotate. The active roller 21 is driven to rotate by the driving member 23, thereby driving the conveyor belt 24 to move, thereby realizing the transportation of metal parts.

[0030] The spraying mechanism 3 includes a paint box 31, a material storage box 32, a spray head 33, and a liquid pump 34. The paint box 31 is fixedly installed on the fixed bracket 1, and conveying ports 35 adapted to the conveyor belt 24 are correspondingly provided on both the left and right sides of the paint box 31 to ensure that the metal parts can smoothly enter and exit when passing through the paint box 31. The material storage box 32 is fixedly installed on the top of the paint box 31. A plurality of groups of spray heads 33 are provided, and all the spray heads 33 are arranged in a matrix in the paint box 31 to ensure that the paint can be evenly distributed on the surface of the metal parts on the conveyor belt 24 during spraying, avoiding uneven spraying or missed spraying, and improving the spraying quality. The input end of the liquid pump 34 is communicated with the material storage box 32, and the output end of the liquid pump 34 is communicated with all the spray heads 33. The liquid pump 34 serves as a power source to transport the paint in the material storage box 32 to each spray head 33 through pipelines, realizing precise paint control. This helps to reduce paint waste and ensure the stability of the spraying effect.

[0031] The cleaning mechanism 4 includes a scraping component 41 and a material collection frame 42. The scraping component 41 and the material collection frame 42 are arranged on the fixed bracket 1, and the scraping component 41 is located at one end of the conveyor belt 24. When the conveyor belt 24 moves, the area where the paint accumulates on the surface of the conveyor belt 24 will pass through the scraping component 41, and the scraping component 41 will closely adhere to the surface of the conveyor belt 24 to scrape off the paint on the surface of the conveyor belt 24. The scraping component 41 can be made of wear-resistant and elastic materials to ensure that the surface of the conveyor belt 24 will not be damaged when scraping the paint. The material collection frame 42 is located below the scraping component 41 and is used to collect the scraped paint. When the paint is scraped off by the scraping component 41, it will naturally fall into the material collection frame 42.

[0032] Specifically, through the scraping component 41 in the cleaning mechanism 4, it can closely adhere to the surface of the conveyor belt 24 and effectively scrape off the accumulated paint on the conveyor belt. This avoids the paint from gradually solidifying into a difficult-to-remove paint film after staying on the conveyor belt 24 for a long time. At the same time, it reduces the production interruption time caused by shutdown for cleaning and improves production efficiency. In addition, the paint collected by the material collection frame 42 can be reused after appropriate treatment, which reduces paint waste and production costs.

[0033] Reference Figure 5 、 Figure 6 and Figure 7As shown, in some specific embodiments, in order to achieve quick disassembly and assembly of the scraping plate 46, the scraping assembly 41 includes a fixed seat 45, a scraping plate 46, a limiting rod 47, and a return spring 48. When the conveyor belt 24 moves, the area where the paint accumulates on the surface of the conveyor belt 24 will pass by the scraping plate 46, and the scraping plate 46 will closely adhere to the surface of the conveyor belt 24, thereby scraping off the paint on the surface of the conveyor belt 24. The fixed seat 45 is fixedly arranged on the fixed bracket 1. A chute 49 is provided on the fixed seat 45. The limiting rod 47 is slidably arranged in the chute 49. One end of the return spring 48 is fixedly connected to the chute 49, and the other end of the return spring 48 is fixedly connected to the limiting rod 47. The scraping plate 46 is provided with a limiting groove 410 that cooperates with the limiting rod 47.

[0034] Specifically, one end of the limiting rod 47 is provided with an inverted buckle 411. The limiting groove 410 is a through groove. When the limiting rod 47 is completely inserted into the limiting groove 410, the inverted buckle 411 buckles the notch of the limiting groove 410, thereby fixing the scraping plate 46 on the fixed seat 45. It should be noted that in order to prevent the limiting rod 47 from shaking in the limiting groove 410, the limiting rod 47 is in sliding contact and cooperation with the limiting groove 410, that is, after being installed in place, the outer wall of the limiting rod 47 fits with the inner wall of the limiting groove 410. Therefore, the whole inverted buckle 411 needs to have a certain elasticity, that is, when the limiting rod 47 is inserted into the limiting groove 410, the inverted buckle 411 undergoes bending deformation, and when the inverted buckle 411 passes out of the limiting groove 410, it bounces back to its original state and then buckles the notch of the limiting groove 410.

[0035] As the scraping plate 46 is used for a longer time, the surface of the scraping plate 46 will be worn and corroded, resulting in a decrease in the paint scraping efficiency. By quickly disassembling and replacing the scraping plate 46, the downtime required for replacing the scraping plate 46 can be reduced, thereby improving work efficiency.

[0036] Reference Figure 2 As shown, in some specific embodiments, in order to prevent paint mist or liquid paint from splashing onto the conveyor belt 24 or the surrounding environment, the spraying mechanism 3 further includes isolation curtains 36. There are two groups of isolation curtains 36, and they are fixedly installed at the corresponding conveying ports 35. The isolation curtains 36 can effectively block the diffusion of paint mist generated during the spraying process to the surrounding environment, reducing the pollution to the working environment and operators.

[0037] Reference Figure 2As shown, in some specific embodiments, in order to recover and utilize the paint scraped off by the scraping component 41, the spraying mechanism 3 further includes a suction pump 37. The input end of the suction pump 37 is connected to the material receiving frame 42 through a pipeline to ensure that the paint can be smoothly sucked in. Similarly, the output end of the suction pump 37 is also connected to the storage tank 32 through a pipeline so as to re - convey the paint to the storage tank 32. By recycling and re - using the paint, the waste and discard of the paint are reduced, the utilization rate of the paint is improved, and the production cost of spraying is lowered.

[0038] Reference Figure 4 As shown, in some specific embodiments, in order to improve the purity of paint recovery and the efficiency of re - use, a filter screen 43 is fixedly installed in the material receiving frame 42, and the filter screen 43 is located at the input end of the suction pump 37. During the process that the paint is scraped off by the scraping component 41 and falls into the material receiving frame 42, some impurities may be brought in, such as metal chips, dust, etc. Through the filtration of the filter screen 43, the impurities in the paint are removed, thereby improving the purity and quality of the paint.

[0039] Reference Figure 2 and Figure 4 As shown, in some specific embodiments, in order to further improve the efficiency of the cleaning mechanism 4, the cleaning mechanism 4 further includes baffle plates 44. There are two groups of baffle plates 44, which are respectively fixedly installed at both ends of the scraping component 41. When the scraping component 41 scrapes the paint on the surface of the conveyor belt 24, some paint may splash due to the impact force or the residual kinetic energy of spraying. The baffle plates 44 are located at both ends of the scraping component 41, and can effectively block the splashing paint, preventing it from splashing onto other parts of the equipment or the surrounding environment. At the same time, due to the blocking effect of the baffle plates 44, the splashing paint will be guided into the material receiving frame 42, thereby increasing the collection efficiency of the paint. This helps to reduce the waste of paint and makes the recycling and re - use of paint more convenient.

[0040] For the convenience of those skilled in the art to understand the embodiments of the present solution, the working principle of the embodiments of the present solution will be described below in combination with a specific application scenario:

[0041] During actual use, first, the paint is added to the storage tank 32 to ensure sufficient paint. Then, the liquid pump 34 is started to convey the paint from the storage tank 32 to the spray head 33 for waiting for spraying. At the same time, the driving member 23, the rotating motor, is started to drive the driving roller 21 to rotate, thereby driving the conveyor belt 24 to move.

[0042] When the metal part is placed on the conveyor belt 24, as the conveyor belt 24 moves, the metal part will pass through the delivery port 35 of the painting tank 31. Inside the painting tank 31, the spray head 33 will evenly spray the paint on the surface of the metal part to achieve the spraying operation. During the spraying process, the isolation curtain 36 can effectively block the diffusion of paint mist to the surrounding environment and reduce pollution.

[0043] When the area where the paint accumulates on the surface of the conveyor belt 24 passes through the scraping component 41, the scraping component 41 clings to the surface of the conveyor belt 24 to scrape off the accumulated paint on the conveyor belt 24. At this time, the baffle plates 44 are located at both ends of the scraping component 41, which can effectively block the splashing of the paint and guide it into the material collection frame 42.

[0044] When installing the scraping plate 46, place the scraping plate 46 on the fixed seat 45, and the limiting rod 47 is inserted into the limiting groove 410 under the support of the return spring 48. One end of the limiting rod 47 is provided with an inverted buckle 411. When the limiting rod 47 is completely inserted into the limiting groove 410, the inverted buckle 411 will latch onto the notch of the limiting groove 410, thereby fixing the scraping plate 46. When disassembling, just squeeze the inverted buckle 411 to make the inverted buckle 411 disengage from the notch, and then move the limiting rod 47 to easily remove the scraping plate 46.

[0045] After the paint falls into the material collection frame 42, it will pass through the filter screen 43 for filtration to remove impurities therein and improve the purity of the paint. At the same time, the suction pump 37 starts to work, sucks the paint in the material collection frame 42 through the pipeline, and then transports it to the storage tank 32 to achieve the recycling and reuse of the paint.

[0046] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
