[0002] PU moldings, also known as polyurethane moldings, are a new type of decorative material. PU moldings produce less dust during production, which is harmless to human respiration and is more environmentally friendly. Due to their durability, moisture resistance, light weight, easy cleaning, environmental friendliness, and wide applicability, PU moldings have become the preferred material for many people when decorating. During the production of PU moldings, it is necessary to use automated PU molding spraying and purification equipment to spray the surface of the PU moldings according to requirements.

For example, when using this device, the entire surface of the PU line needs to be sprayed, but it is inconvenient to rotate the PU line, which has great limitations. In addition, it is inconvenient to collect excess paint, which can easily affect the environment inside the spraying box.

[0004] Therefore, we propose an automated PU line spraying and purification equipment to improve the above-mentioned problems. Utility Model Content

[0013] As a further technical solution of this utility model, the activated carbon adsorption particle plate is disposed inside the exhaust port and is disposed on the right side of the fan.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the automated equipment for spraying and purifying PU lines not only facilitates the slow rotation of PU lines and the collection of excess paint, and facilitates the limiting and fixing of PU lines, but also facilitates the purification of gas.

[0015] (1) By setting up a large gear, a rotating shaft, a storage box, a support block, a drive motor, a connecting shaft and a rotating block, the drive motor is started when the PU line needs to be rotated. The drive motor drives the small gear to rotate through the connecting shaft. The small gear can drive the support plate to rotate through the large gear and the rotating shaft, so that the PU line between the support block and the clamping plate can rotate, so that the PU line can be easily sprayed with a full coating. Using the small gear and the large gear to drive the PU line to rotate can make the PU line rotate slowly, preventing the PU line from rotating too fast and affecting the coating effect. Excess paint will flow into the inside of the storage box, and the storage box can collect the paint.

[0016] (2) By setting up a corrugated pad, a servo motor, a threaded rod, a threaded sleeve and a connecting plate, the corrugated pad can shield the paint and prevent the paint from accidentally spraying into the interior of the housing and affecting the operation of the threaded rod. When the servo motor is started, the servo motor drives the threaded rod to rotate inside the housing, which can cause the threaded sleeve to drive the connecting plate and the clamping plate to descend. The descent of the clamping plate can limit and fix the PU line to prevent the PU line from tilting accidentally.

[0017] (3) The system is equipped with a fan, an exhaust port, a sealing plate, a frame, and an activated carbon adsorption particle plate. When spraying, the fan is turned on and the fan draws out the gas inside the spray box through the exhaust port. The activated carbon adsorption particle plate inside the frame can filter the extracted gas, thereby purifying and filtering the gas and preventing the gas from being directly discharged and polluting the environment. When the activated carbon adsorption particle plate needs to be replaced, pull the handle at the front end of the sealing plate. The handle moves the frame and the activated carbon adsorption particle plate out of the exhaust port through the sealing plate. Taking out the activated carbon adsorption particle plate makes it convenient to replace the activated carbon adsorption particle plate. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides an embodiment of an automated PU line spraying and purification equipment, comprising a spraying box 1, a protective shell 2 fixedly connected to the middle position of the bottom of the spraying box 1, a drive motor 28 installed on the right side inside the protective shell 2, a connecting shaft 29 fixedly connected to the output end of the drive motor 28, a small gear 30 fixedly connected to the left side of the connecting shaft 29, a rotating shaft 4 movably connected inside the protective shell 2, a large gear 3 fixedly connected to the bottom of the rotating shaft 4, a support plate 5 fixedly connected to the top of the rotating shaft 4, a storage box 24 fixedly connected to the top of the support plate 5, a support block 25 fixedly connected to the middle position inside the storage box 24, a connecting plate 11 set at the top of the inside of the spraying box 1, a fixing block 31 fixedly connected to the right side of the bottom of the connecting plate 11, a movable rotating block 32 set inside the fixing block 31, a clamping plate 33 fixedly connected to the bottom of the rotating block 32, a discharge pipe 26 fixedly connected to the bottom right side of the storage box 24, and a second valve 27 installed on the discharge pipe 26;

[0025] The small gear 30 is located on the right side of the top of the large gear 3. The small gear 30 and the large gear 3 cooperate with each other. The clamping plate 33 rotates at the bottom of the fixed block 31 via the rotating block 32. The bottom right side of the spray box 1 is provided with a material box 21. The right side of the spray box 1 is equipped with a pump body 18. The output end of the pump body 18 is fixedly connected to a discharge pipe 19. The output end of the pump body 18 is fixedly connected to a feed pipe 20. The left side of the discharge pipe 19 is fixedly connected to a branch pipe 17. The left side of the branch pipe 17 is fixedly connected to a spray pipe 12. A first valve 13 is installed on the spray pipe 12. The bottom end of the feed pipe 20 passes through the inside of the material box 21 and extends to the bottom of the inside of the material box 21. The spray pipe 12 is located on the right side inside the spray box 1.

[0026] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, when the PU line needs to be rotated, the drive motor 28 is activated. The drive motor 28 drives the pinion 30 to rotate through the connecting shaft 29. The pinion 30 drives the support plate 5 to rotate through the large gear 3 and the rotating shaft 4, thereby allowing the PU line between the support block 25 and the clamping plate 33 to rotate. This allows the PU line to be easily and comprehensively sprayed. Using the pinion 30 and the large gear 3 to drive the PU line to rotate allows the PU line to rotate slowly, preventing the PU line from rotating too fast and affecting the spraying effect. Excess paint will flow into the inside of the collection box 24, which can collect the paint.

[0027] A housing 7 is fixedly connected to the left side inside the spray box 1. A servo motor 8 is installed at the bottom inside the housing 7. A threaded rod 9 is fixedly connected to the output end of the servo motor 8. A threaded sleeve 10 is provided at the top of the threaded rod 9. A corrugated pad 6 is fixedly connected between the connecting plate 11 and the left side of the bottom inside the spray box 1. The threaded sleeve 10 is fixedly connected to the left side of the connecting plate 11. The threaded rod 9 and the threaded sleeve 10 are connected by threads.

[0028] Specifically, such as Figure 1 As shown, the corrugated pad 6 can shield the paint and prevent it from accidentally spraying into the interior of the housing 7 and affecting the operation of the threaded rod 9. The servo motor 8 is started, and the servo motor 8 drives the threaded rod 9 to rotate inside the housing 7, which can cause the threaded sleeve 10 to drive the connecting plate 11 and the clamping plate 33 to descend. The descent of the clamping plate 33 can limit and fix the PU line, preventing the PU line from tilting accidentally.

[0029] An exhaust port 15 is fixedly connected to the top right side of the spray box 1. A fan 14 is installed on the left side inside the exhaust port 15. A sealing plate 16 is set on the left side of the front end of the exhaust port 15. A frame 22 is fixedly connected to the left and right sides of the rear end of the sealing plate 16. An activated carbon adsorption particle plate 23 is installed inside the frame 22. The activated carbon adsorption particle plate 23 is set inside the exhaust port 15 and is set on the right side of the fan 14.

[0030] Specifically, such as Figure 1 and Figure 2 As shown, when spraying, the fan 14 is started. The fan 14 extracts the gas inside the spray box 1 through the exhaust port 15. The activated carbon adsorption particle plate 23 inside the frame 22 can filter the extracted gas, thereby purifying and filtering the gas and preventing the gas from being directly discharged and polluting the environment. When the activated carbon adsorption particle plate 23 needs to be replaced, pull the handle at the front end of the sealing plate 16. The handle moves the frame 22 and the activated carbon adsorption particle plate 23 out of the exhaust port 15 through the sealing plate 16. Taking out the activated carbon adsorption particle plate 23 makes it convenient to replace it.

[0031] Working Principle: In use, the PU line is placed between the support block 25 and the clamping plate 33. After placement, the servo motor 8 is activated. The servo motor 8 drives the threaded rod 9 to rotate inside the housing 7, thereby causing the threaded sleeve 10 to lower the connecting plate 11 and the clamping plate 33. The lowering of the clamping plate 33 limits and fixes the PU line, preventing accidental tilting. The corrugated pad 6 shields the paint, preventing it from accidentally spraying into the housing 7 and affecting the operation of the threaded rod 9. The pump body 18 and drive motor 28 are activated. The pump body 18 draws the paint into the branch pipe 17 through the inlet pipe 20 and outlet pipe 19, and then sprays it onto the surface of the PU line through the spray pipe 12. The drive motor 28 drives the pinion 30 to rotate through the connecting shaft 29. The pinion 30 drives the support plate 5 to rotate through the large gear 3 and the rotating shaft 4, thereby allowing the PU line between the support block 25 and the clamping plate 33 to rotate. The PU lines rotate, allowing for easy and comprehensive spraying. The rotation of the PU lines is driven by small gear 30 and large gear 3, ensuring a slow rotation to prevent excessive speed from affecting the spraying effect. Excess paint flows into the collection box 24 for collection. During spraying, the fan 14 is activated, extracting gas from inside the spray box 1 through the exhaust port 15. The activated carbon adsorption particle plate 23 inside the frame 22 filters the extracted gas, purifying it and preventing direct environmental pollution. To replace the activated carbon adsorption particle plate 23, pull the handle at the front of the sealing plate 16. The handle, through the sealing plate 16, moves the frame 22 and the activated carbon adsorption particle plate 23 out of the exhaust port 15, facilitating replacement.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
