[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0031] Referring to Figure 1 , Figure 3 , Figure 4 , an embodiment provided by the present invention: A planar oil spraying and screen printing device for plastic part processing, including an operating table 1. Two hydraulic rods 2 are fixedly connected to the left and right of the upper side inside of the operating table 1. The output ends of the hydraulic rods 2 are fixedly connected to mounting seats 3. Slide blocks 5 are slidably connected to the corresponding inner sides of the mounting seats 3. Clamping plates 4 are fixedly connected to the corresponding sides of the slide blocks 5. An electric push rod 6 is fixedly connected to the bottom of the inner wall of the mounting seat 3. The output end of the electric push rod 6 is fixedly connected to an outer shell 7. A telescopic assembly is fixedly connected to one side of the inner wall of the outer shell 7. The telescopic assembly is used to assist in fixing the clamping plate 4. A block 10 is fixedly connected to the corresponding side of the telescopic assembly. The block 10 is slidably connected inside the slide block 5;

[0032] The telescopic assembly includes a telescopic member 8. The telescopic member 8 is fixedly connected to one side of the inner wall of the outer shell 7. A first spring 9 is sleeved outside the telescopic member 8. One end of the first spring 9 is fixedly connected to one side inner wall of the outer shell 7. The other end of the first spring 9 is fixedly connected to one side of the block 10.

[0033] By placing the injection molded part on the operating table 1, the hydraulic rod 2 is activated to drive the clamping plate 4 to clamp and fix the injection molded part. When the shapes of the injection molded parts are different, the electric push rod 6 is activated to move the outer shell 7. The bottom of the clamping block 10 and the card slots formed inside the sliding block 5 are both inclined, and the clamping block 10 is not fully inserted into the inside of the card slot and is not completely locked. When the outer shell 7 drives the clamping block 10 to move downward, the clamping block 10 can smoothly move out of the inside of the card slot and is moved to the inside of the outer shell 7 by squeezing the edge of the card slot, and the telescopic member 8 and the first spring 9 are squeezed to generate a resilience force, causing the clamping block 10 to separate from the sliding block 5. Then, the clamping plate 4 can be pulled upward for disassembly, so as to disassemble and replace the clamping plate 4, enabling it to clamp and fix injection molded parts of different model sizes and avoiding offset printing failure during the printing process.

[0034] Refer to Figure 1 、 Figure 2 , a support frame 11 is fixedly connected to the upper rear side of the operating table 1. A cross beam 12 is slidably connected to the front side inside the support frame 11. A moving frame 13 is slidably connected to the inside of the cross beam 12. A connecting cylinder 14 is fixedly connected to the front side inside the moving frame 13. A connecting box 15 is fixedly connected to the bottom of the connecting cylinder 14. A plurality of evenly distributed spray nozzles 16 are fixedly connected to the bottom of the connecting box 15. Scraping plates 17 are clamped to both the left and right sides of the connecting box 15. A feeding component is fixedly connected to the upper part of the connecting cylinder 14, and the feeding component is used to convey the paint into the inside of the connecting box 15;

[0035] The feeding component includes a conveying pipe 18. One end of the conveying pipe 18 is fixedly connected to the upper part of the connecting cylinder 14. The other end of the conveying pipe 18 is fixedly connected to a suction pump 19. The output end of the suction pump 19 is fixedly connected to a suction pipe 20. One end of the suction pipe 20 is fixedly connected to an outer box 21. The outer box 21 is fixedly connected to the inner bottom side of the operating table 1. A connecting pipe 22 is slidably connected to the inside of the outer box 21. A storage box 23 is fixedly connected to the upper part of the outer box 21. The upper side of the storage box 23 is fixedly connected to the upper side inside the operating table 1. Both the suction pipe 20 and the storage box 23 communicate with the connecting pipe 22.

[0036] By activating the suction pump 19, it drives the suction pipe 20 to suck the paint in the storage box 23, injects it into the connecting box 15 through the conveying pipe 18 and the connecting cylinder 14 for storage, and the spray nozzles 16 spray the paint for silk screen printing. When the moving frame 13 slides inside the cross beam 12, the connecting box 15 is driven by the connecting cylinder 14 to make the spray nozzles 16 spray the paint onto the screen plate 24. At the same time, the scraping plates 17 scrape the paint to make it evenly silk screen printed on the injection molded part, and the scraped paint flows into the inside of the storage box 23 through the connecting pipe 22 for recycling, and is filtered by the internal filter screen to avoid impurities in the paint, so as to recycle the paint and reduce resource waste.

[0037] Refer toFigure 1 , Figure 2 , Figure 5 , on both the left and right sides inside the crossbeam 12, there are fixedly connected fixing frames 25. Inside the fixing frames 25, there is a wire mesh plate 24 slidably connected. Inside the upper side of the fixing frames 25, there are connecting rods 27 slidably connected both front and back. One end of the connecting rod 27 is fixedly connected to a connecting plate 26, and the other end of the connecting rod 27 is fixedly connected to a fixing plate 29. The fixing plate 29 is in fitting connection with the upper part of the wire mesh plate 24. On the upper side of the outer part of the connecting rod 27, there is a second spring 28 sleeved. One end of the second spring 28 is fixedly connected to the bottom of the connecting plate 26, and the other end of the second spring 28 is fixedly connected to the upper part of the fixing frame 25.

[0038] By pulling the connecting plate 26, the connecting rod 27 slides inside the fixing frame 25 and squeezes the second spring 28 to generate a resilience force, so that the fixing plate 29 no longer fixes the wire mesh plate 24. Then, the wire mesh plate 24 can be pulled out of the inside of the fixing frame 25 for cleaning, enabling quick disassembly and cleaning of the wire mesh plate 24, ensuring the silk screen printing quality of the injection molded parts. Since it is necessary to prevent the wire mesh plate 24 from moving when the squeegee 17 scrapes the paint, affecting the silk screen printing effect, it needs to be fixed.

[0039] Working principle: When the device needs to be used, place the injection molded part on the operating table 1 and start the hydraulic rod 2 to drive the clamping plate 4 to clamp and fix the injection molded part. When the shapes of the injection molded parts are different, start the electric push rod 6 to move the outer shell 7. Since the bottom of the clamping block 10 and the card slots opened inside the sliding block 5 are both inclined, when the outer shell 7 drives the clamping block 10 to move downward, the clamping block 10 is moved to the inside of the outer shell 7 and separated from the sliding block 5 by the extrusion of the edge of the card slot. Then, the clamping plate 4 can be pulled upward for disassembly, realizing the disassembly and replacement of the clamping plate 4, enabling it to clamp and fix injection molded parts of different models and sizes, and avoiding printing failure due to offset during the printing process.

[0040] By pulling the connecting plate 26, the connecting rod 27 slides inside the fixing frame 25 and squeezes the second spring 28, so that the fixing plate 29 no longer fixes the wire mesh plate 24. Then, the wire mesh plate 24 can be pulled out of the inside of the fixing frame 25 for cleaning. After the moving frame 13 drives the connecting box 15 and the nozzle 16 sprays the paint onto the operating table 1, it flows into the inside of the storage tank 23 through the connecting pipe 22 for recycling, realizing quick disassembly and cleaning of the wire mesh plate 24 and recycling of the paint, ensuring the silk screen printing quality of the injection molded parts and reducing resource waste.

[0041] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features.
