Description

Technical Field

[0001] The utility model relates to the technical field of automobile decoration part spraying, and specifically relates to a spraying device for automobile decoration parts. Background Technique

[0002] Automobile decoration parts are a kind of automobile parts. They not only have practicality, but also can enhance the beauty of the automobile. Before the automobile leaves the factory, coatings will be sprayed on the decoration parts. Spraying is not only for beauty, but also can play a role in protecting the decoration parts, such as preventing corrosion, improving wear resistance and weather resistance, etc. At the same time, by spraying coatings with different colors and textures, personalized customization can also be realized to meet the different needs of consumers. Therefore, a spraying device for automobile decoration parts appears on the market.

[0003] For example, the existing Chinese patent (publication number: CN219683017U) discloses a spraying device. The spraying device is provided with a paint anti-settling mechanism, including a spraying device, a paint anti-settling mechanism located below the spraying device, and a spraying shape adjusting mechanism located on the right side of the spraying device. A pressing place is arranged on the left side of the spraying device. A spray pot is connected to the bottom of the spraying device. A paint inlet is arranged on the right side of the spray pot. A spray head is installed on the left side of the first adjusting block.

[0004] However, the above-mentioned designed spraying device still has some disadvantages in actual use: Although the spraying device can spray the paint on the decoration parts through the spray head, during long-term spraying work, there will undoubtedly be a certain amount of paint residue inside the spray head. If it is not cleaned regularly, the paint remaining at the spray head will condense with dust and impurities in the air to form a blockage that blocks the spray head. If the blockage is serious, the spraying device cannot be used normally.

[0005] Therefore, we designed a spraying device for automobile decoration parts to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a spraying device for automobile decoration parts to solve the problems put forward in the above background technique.

[0007] To solve the above technical problems, a spraying device for automobile decoration parts provided by the utility model includes a spraying box. One side of the spraying box is fixedly provided with a spray head. A limiting cylinder is fixedly arranged inside the spraying box. A reciprocating rod is slidably inserted into the inner circle of the limiting cylinder. One end of the reciprocating rod is slidably inserted into the spray head and is provided with a push plate. A sealing ring is sleeved on the push plate. The other end of the reciprocating rod is fixedly provided with a U-shaped part. A roller is rotatably arranged on the U-shaped part. A driving component is also arranged inside the spraying box, and the driving component is connected to the roller.

[0008] Further, the driving component includes a cam and a motor. The cam is fixedly sleeved on the driving end of the motor, and the motor is arranged inside the spraying box. The cam mechanism has a simple and compact structure, is convenient to design, and can accurately achieve the required motion law.

[0009] Further, a cavity is formed inside the spraying box. The limiting cylinder and the motor are both fixedly arranged inside the cavity. One end of the reciprocating rod penetrates through the cavity and extends into the spray head.

[0010] Further, a partition is fixedly installed inside the cavity. The partition is located below the motor and is made of stainless steel. The stainless steel material can ensure its high-temperature and corrosion-resistant properties, and can ensure the normal operation of the motor inside the cavity to prevent the paint from interfering with the motor.

[0011] Further, a feed inlet is fixedly inserted on one side of the spraying box. A sealing cover is movably sleeved on the feed inlet. The feed inlet is located obliquely below the partition. The setting of the sealing cover can ensure the tightness of the paint inside the spraying box and prevent paint pollution.

[0012] Further, an L-shaped pipe is fixedly inserted on the side of the spraying box away from the feed inlet. A material pumping pump is arranged at the other end of the L-shaped pipe. A feed pipe is fixedly inserted at the bottom of the spray head. The other end of the feed pipe is fixedly connected to the top end of the material pumping pump.

[0013] Further, electric heating wires are arranged on the side surface of the push plate. The number of the electric heating wires is two. The two electric heating wires are symmetrically embedded on one side of the push plate. The setting of the electric heating wires can melt the solidified paint while scraping the inner wall of the spray head for convenient discharge. A sealing ring is sleeved on the push plate to prevent the melted paint from flowing back into the cavity during the reciprocating motion.

[0014] Further, the top end of the feed pipe is flush with the inner ring of the spray head. A pin shaft is arranged inside the feed pipe. A baffle is rotatably sleeved on the pin shaft. A sealing gasket is fixedly sleeved on the baffle. The sealing gasket abuts against the inner ring of the feed pipe. A limiting block is fixedly arranged on the inner ring of the feed pipe. The limiting block abuts against the baffle. When the push plate discharges the melted paint from the spray head, the setting of the limiting block prevents the melted paint from flowing back into the feed pipe to cause blockage of the inner ring of the feed pipe. The material of the sealing gasket is fluororubber, which has high temperature resistance and good sealing performance to prevent the paint from flowing in through the gap.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: When spraying for a long time, there will undoubtedly be some paint residues and coagulated blockages inside the spray head. At this time, the cam mechanism component drives the push plate to reciprocate inside the spray head to scrape the coagulated blockages inside the spray head, heat and melt them, and then discharge them, ensuring the normal use of the spray head in daily use and improving the work efficiency of the staff.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows: when the paint enters the nozzle from the feed pipe, due to the pin shaft, the paint can enter the nozzle more easily. When the paint spraying is completed, the melted paint will not flow back into the feed pipe due to the blockage of the limit block. The fluororubber on the inner ring of the feed pipe can also prevent the paint from flowing into the fine gap, preventing the paint from flowing back and forming blockages on the inner wall of the feed pipe, which can further improve the cleaning effect of the equipment.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-3 , the present utility model provides a technical solution: a spraying device for automobile decorative parts, including a spraying box 1, a nozzle 9 is fixedly arranged on one side of the spraying box 1, a limit cylinder 15 is fixedly arranged in the spraying box 1, a reciprocating rod 7 is slidably inserted into the inner ring of the limit cylinder 15, one end of the reciprocating rod 7 is slidably inserted into the nozzle 9 and is provided with a push plate 10, a sealing ring is sleeved on the push plate 10, the other end of the reciprocating rod 7 is fixedly provided with a U-shaped part 5, a roller 4 is rotatably arranged on the U-shaped part 5, and a driving component is further arranged in the spraying box 1, and the driving component is connected with the roller 4;

[0023] The driving component includes a cam 3 and a motor 8, the cam 3 is fixedly sleeved on the driving end of the motor 8, and the motor 8 is arranged in the spraying box 1;

[0024] A cavity 2 is provided inside the spraying box 1. The limiting cylinder 15 and the motor 8 are both fixedly arranged inside the cavity 2. One end of the reciprocating rod 7 penetrates through the cavity 2 and extends into the spray head 9;

[0025] Electric heating wires 11 are arranged on the side surface of the push plate 10. The number of the electric heating wires 11 is two. The two electric heating wires 11 are symmetrically embedded on one side of the push plate 10;

[0026] During specific implementation, during the daily spraying work, there will be a certain amount of paint residue inside the spray head. At this time, the motor 8 is started. The driving end of the motor 8 drives the cam 3 to move. The cam 3 abuts against the roller 4 to drive the reciprocating rod 7 to reciprocate inside the spray head 9. While the reciprocating rod 7 reciprocates inside the spray head 9, it scrapes the solidified paint on the inner wall of the spray head 9 and heats and melts the paint at the same time, and then discharges from the spray head 9, avoiding the problem that the spraying equipment cannot be used normally caused by the blockage of the spray head by the blockage, and improving the work efficiency of the staff.

[0027] Refer to Figures 1-3 , a feed port 19 is fixedly inserted on one side of the spraying box 1. A sealing cover 20 is movably sleeved on the feed port 19. The feed port 19 is located obliquely below the partition plate 18. The setting of the sealing cover 20 can ensure the sealing property of the paint inside the spraying box 1, prevent paint pollution, and also facilitate adding paint into the spraying box 1.

[0028] Refer to Figures 1-3 , a partition plate 18 is fixedly installed inside the cavity 2. The partition plate 18 is located below the motor 8 and its material is stainless steel. The stainless steel material can ensure its own high-temperature and corrosion-resistant property characteristics, and can ensure the normal operation of the motor 8 inside the cavity 2 to prevent the paint from causing a certain interference to the motor 8.

[0029] Refer to Figures 1-3 , an L-shaped pipe 6 is fixedly inserted on the side of the spraying box 1 away from the feed port 19. A pumping pump 17 is arranged at the other end of the L-shaped pipe 6. A feed pipe 16 is fixedly inserted at the bottom of the spray head 9. The other end of the feed pipe 16 is fixedly connected to the top end of the pumping pump 17. The mutual cooperation of the feed pipe 16 and the pumping pump is more conducive to transporting the paint.

[0030] Refer to Figures 1-3, the top end of the feed pipe 16 is flush with the inner ring of the spray head 9. A pin shaft is arranged inside the feed pipe 16. A baffle 13 is rotatably sleeved on the pin shaft. A sealing gasket 12 is fixedly sleeved on the baffle 13. The sealing gasket 12 abuts against the inner ring of the feed pipe 16. A limiting block 14 is fixedly arranged on the inner ring of the feed pipe 16. The limiting block 14 abuts against the baffle 13. When the push plate 10 discharges the melted paint from the spray head 9, the setting of the limiting block 14 prevents the melted paint from flowing back into the feed pipe 16 and causing blockage of the paint in the inner ring of the feed pipe 16. The sealing gasket 12 is made of fluororubber, which is heat-resistant and has good sealing performance to prevent the paint from flowing in through the gaps.

[0031] Working principle: When spraying operations are to be carried out, remove the sealing cover 20 and pour the spraying raw materials into the cavity 2. The feeding pump 17 starts to pump the paint and convey it into the spray head 9, and cooperates with the robotic arm to carry out multi-angle spraying operations. During long-term spraying work, there will undoubtedly be a certain amount of paint residue inside the spray head. At this time, turn on the motor 8. The driving end of the motor 8 drives the cam 3 to move. The cam 3 abuts against the roller 4 and drives the reciprocating rod 7 to reciprocate inside the spray head 9. When the motor 8 is turned on, the electric heating wire 11 also starts to heat up. While the reciprocating rod 7 reciprocates, it scrapes the solidified paint on the inner wall of the spray head 9 and heats and melts the paint at the same time, and then discharges it from the spray head 9, avoiding the problem that the spraying equipment cannot be used normally due to blockage of the spray head by the blockage, improving the work efficiency of the staff. In addition, when the paint enters the spray head 9 from the feed pipe 16, due to the pin shaft, the paint can enter the spray head 9 more easily. When the paint spraying is completed, the melted paint will not flow back into the feed pipe 16 due to the blockage of the limiting block 14. The fluororubber on the inner ring of the feed pipe 16 can also prevent the paint from flowing in through the small gaps, preventing the paint from flowing back and forming blockages on the inner wall of the feed pipe 16, which can further improve the cleaning effect of the equipment.

[0032] In addition, it should be noted that the robotic arm includes motion components such as oil cylinders, air cylinders, racks, cams, etc. which are components that drive the movement of the arm. The guiding device and the arm, and the robotic arm and the installation of the robotic arm are prior arts, so this specification will not explain them in detail.
