Description

Technical Field

[0001] This utility model relates to the field of chair leg coating production technology, and in particular to a chair leg UV vacuum coating production line. Background Technology

[0002] Chair legs are the supporting components of a chair, usually located at the bottom of the chair. They are used to transfer the weight of the chair to the ground and maintain the stability of the chair. The UV vacuum coating production line uses a vacuum environment for coating, which allows the UV coating to be evenly covered on the surface of the chair legs. This avoids phenomena such as drips and orange peel that may occur in traditional coating methods, ensuring that the chair legs have a smooth, flat appearance and consistent color.

[0003] After sanding and cleaning, the wooden chair legs are fixed in a fixture and sent into the coating room of the UV vacuum coating production line. After vacuuming, an appropriate amount of UV coating is evenly sprayed with an electrostatic spray gun, with a thickness of 30-50 micrometers. Then, it is cured under 365-405nm ultraviolet light for tens of seconds to a few minutes. After curing, the chair legs are put into the material. At the same time, the quality is inspected at each stage. Unqualified chair legs are reworked or scrapped.

[0004] In existing technologies, some chair leg UV vacuum coating production lines encounter chair legs of different widths during use. In such cases, it is necessary to use a compatible model. When enterprises need to quickly switch production tasks for chair legs of different widths, the downtime and debugging time required for changing models is relatively long. This makes it difficult to respond to the changing demands of diversified markets and small-batch orders in a timely manner. As a result, enterprises find it difficult to quickly adjust production arrangements when faced with urgent customer orders or frequent changes in product specifications, leading to reduced production efficiency. Therefore, in order to address the above shortcomings, a chair leg UV vacuum coating production line is proposed to solve the above problems. Utility Model Content

[0012] As a further description of the above technical solution:

The top sides of the multiple support legs are fixedly connected to the four corners of the bottom side of the top plate. Two guide plates are fixedly connected to the left and right ends of the bottom side of the top plate.

[0014] As a further description of the above technical solution:

In this utility model, the trapezoidal plate receives a reaction force, which in turn applies a force in the opposite direction to the two fixed columns, thereby pushing the sliding disc to slide and compress the spring. This allows the spring to store elastic potential energy, and the sliding disc then applies a force in the opposite direction to the fixed columns, enabling the trapezoidal plate to press against the conveyor belt and achieve a tight fit. At this point, the coating on the surface of the conveyor belt can be cleaned, thus extending its service life. Attached Figure Description

[0032] 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.

[0033] Reference Figures 2 to 4This utility model provides an embodiment of a UV vacuum coating production line for chair legs, comprising a processing table 1 and a top plate 5. The processing table 1 provides support for the transportation and processing of chair legs. Side plates 2 are fixedly connected to both the front and rear ends of the top side of the processing table 1. Conveyor belts 3 are installed inside the two side plates 2 for transporting chair legs. Support legs 4 are fixedly connected to both the left and right ends of the top side of the side plates 2. The side plates 2 are connected to the four support legs 4 by welding to ensure they can withstand the weight of the chair legs in the production line. The top sides of the multiple support legs 4 are fixedly connected to the four corners of the bottom side of the top plate 5 by welding, so that the support legs 4 can provide stable support for the top plate 5. Two guide plates 6 are fixedly connected to both the left and right ends of the bottom side of the top plate 5, providing guidance for the movement of the chair legs.

[0034] Sliding blocks 7 are slidably connected to both the front and rear ends of the top plate 5, allowing the sliding blocks 7 to slide stably due to the constraint of the top plate 5. A limiting component is fixedly connected to the bottom side of the sliding block 7 to restrict the chair legs and adjust their width. The limiting component includes a clamping plate 8, the top side of which is fixedly connected to the bottom side of the sliding block 7. When the sliding block 7 is subjected to force, it drives the clamping plate 8 to slide synchronously back and forth. Multiple auxiliary wheels 9 are rotatably connected inside the clamping plate 8, reducing friction between the chair legs and the clamping plate 8 when the chair legs are clamped. A connecting plate 10 is fixedly connected to the top side of the sliding block 7, causing the sliding block 7 to slide synchronously when subjected to force. Guide posts 11 are fixedly connected to both the left and right ends of the top plate 5. The top plate 5 is connected to the two guide posts 11 through welding, allowing the guide posts 11 to provide stable guidance. The left and right ends of the two connecting plates 10 are slidably connected to the outside of the two guide posts 11, and the connecting plates 10 can slide stably through the guidance of the guide posts 11.

[0035] An open plate 12 is fixedly connected to one of the adjacent sides of each of the two connecting plates 10. When the open plate 12 is subjected to force, it drives the connecting plates 10 to slide synchronously. A rotating plate 13 is rotatably connected inside the open plate 12. When the rotating plate 13 is subjected to force and rotates, it transmits the rotational force to the open plate 12, which then converts the rotational force into a sliding force. An I-shaped plate 14 is rotatably connected to one of the adjacent ends of each of the two rotating plates 13. When the I-shaped plate 14 is subjected to force, it transmits the rotational force to the rotating plate 13, enabling the rotating plate 13 to rotate. A support shaft 15 is rotatably connected inside the I-shaped plate 14, providing the axis for its rotation. The two support shafts 15 are fixedly connected to the inner walls of the front and rear ends of the top plate 5, respectively. The top plate 5 is connected to the two support shafts 15 through welding, allowing the support shafts 15 to stably guide the rotation of the I-shaped plate 14. The right end of the I-shaped plate 14 is rotatably connected to a rotating block 16. After being subjected to force, the rotating block 16 drives the I-shaped plate 14 to rotate around the support shaft 15.

[0036] A cylinder 17 is fixedly connected to the rear side of one of the rotating blocks 16, providing a drive source. The drive end of the cylinder 17 is fixedly connected to the front side of the other rotating block 16, and through reaction force, the cylinder 17 can transmit force to both rotating blocks 16. Connecting plates 18 are fixedly connected to adjacent sides of the two I-shaped plates 14, and the rotation of the I-shaped plates 14 drives the connecting plates 18 to rotate synchronously. A transmission column 19 is fixedly connected to the left side of the connecting plate 18, transmitting rotational force to the transmission column 19. Sliding frames 20 are slidably connected to the outside of the two transmission columns 19. Activating one transmission column 19 causes the sliding frame 20 to slide, allowing the sliding frame 20 to transmit sliding force to the other transmission column 19, enabling the other transmission column 19 to rotate. The structure of the sliding frame 20 is adapted to the transmission column 19. Guide blocks 21 are fixedly connected to both the upper and lower sides of the sliding frame 20, and the sliding frame 20 drives the guide blocks 21 to slide synchronously. Guide openings 22 are provided on both the upper and lower sides of the inner wall of the top plate 5. The size of the guide openings 22 is adapted to the guide block 21. The guide block 21 is slidably connected to the inside of the guide opening 22, so that the guide block 21 can slide stably.

[0037] Reference Figure 1 and Figure 5 A vacuum spraying machine 23 is fixedly connected to the top left end of each of the two side panels 2. The vacuum spraying machine 23 uses spraying technology to evenly spray paint onto the chair legs in a vacuum environment, ensuring coating quality and adhesion. A base plate is fixedly connected to the bottom of the processing table 1, providing support and stability for the production line. A connecting box 24 is fixedly connected to the left side of the base plate, and the base plate and connecting box 24 are connected by welding to form the production line. A support box 25 is fixedly connected to the top of the connecting box 24, and the connecting box 24 and support box 25 are connected by welding to provide stable support for the support box 25. Multiple UV lamps 26 are installed on the bottom side of the support box 25, which can quickly cure the sprayed chair legs, improving production efficiency. A concave frame 27 is fixedly connected to the bottom left end of each of the two side panels 2, and the two side panels 2 are connected by welding to provide stable support for the concave frame 27.

[0038] A drive assembly providing a drive source is fixedly connected to the middle of the concave frame 27. The drive assembly includes an electric push rod 28, the bottom end of which is fixedly connected to the middle of the concave frame 27. The concave frame 27 and the electric push rod 28 are connected by welding, allowing the electric push rod 28 to stably provide a drive source. A push plate 29 is fixedly connected to the drive end of the electric push rod 28, and the push plate 29 is pushed to slide by driving the electric push rod 28. Connecting cylinders 30 are fixedly connected to both the front and rear ends of the drive assembly. The front and rear ends of the push plate 29 are respectively fixedly connected to the bottom ends of the two connecting cylinders 30, and the push plate 29 drives the two connecting cylinders 30 to slide up and down synchronously. A spring 31 is fixedly connected to the bottom side of the inner wall of the connecting cylinder 30. By fixing the spring 31, the spring 31 can be evenly stressed.

[0039] A sliding disc 32 is fixedly connected to the top of the spring 31. The sliding disc 32 slides and compresses the spring 31, allowing the spring 31 to store elastic potential energy, which in turn applies a force in the opposite direction to the sliding disc 32 for resetting. The outer side of the sliding disc 32 is slidably connected to the inner wall of the connecting cylinder 30. The connecting cylinder 30 restricts the sliding disc 32, allowing it to slide vertically up and down. A fixed post 33 is fixedly connected to the top side of the sliding disc 32, transmitting the sliding force to the sliding disc 32. A trapezoidal plate 34 is fixedly connected to the top side of the two fixed posts 33, providing a rigid top. The outer side of the conveyor belt 3 contacts the top side of the trapezoidal plate 34 for cleaning the surface of the support leg 4. Connecting blocks 35 are fixedly connected to both the front and rear sides of the trapezoidal plate 34. The connecting blocks 35 ensure stable movement of the trapezoidal plate 34 within the concave frame 27. The outer sides of the two connecting blocks 35 are slidably connected to the interior of the front and rear ends of the concave frame 27, allowing for stable sliding.

[0040] Working principle: First, the chair legs are placed at the right end of conveyor belt 3, and then conveyor belt 3 is started to transport the chair legs to the processing area. When it is necessary to limit the chair legs of different widths for painting, the drive cylinder 17 pushes the rotating block 16 connected to it. The rotating block 16 transmits the rotational force to the I-shaped plate 14. Under the reaction force, the I-shaped plate 14 rotates around the support shaft 15. The I-shaped plate 14 drives the connecting plate 18 to rotate synchronously, which in turn drives the transmission column 19 to rotate. The transmission column 19 pushes the sliding frame 20. The sliding frame 20 is guided by the guide block 21 to slide horizontally in the guide opening 22. At the same time, the sliding frame 20 will drive the other one after being pushed by one of the transmission columns 19. One drive column 19 pushes the other drive column 19 to transmit force to another rotating block 16, thus achieving synchronous rotation of the two rotating blocks 16. Subsequently, both I-shaped plates 14 will drive a rotating plate 13 to rotate, thereby causing the two open plates 12 to slide to the same side, which in turn causes the sliding block 7 to slide, and then causes the clamping plate 8 to slide. The auxiliary wheel 9 in the clamping plate 8 reduces the friction between the chair legs and the clamping plate 8, ensuring that the chair legs are fixed and stable, so as to achieve the function of limiting the chair corners of different widths, thereby increasing its flexibility and improving work efficiency.

[0041] When the vacuum spraying machine 23 is working, it evenly sprays the paint onto the chair legs in a vacuum environment. After spraying, the conveyor belt 3 continues to transport the chair legs to the UV curing lamp 26. The UV curing lamp 26 quickly cures the sprayed chair legs, improving production efficiency. In addition, the drive electric push rod 28 drives the push plate 29 to slide upwards, thereby causing the two connecting cylinders 30 to slide. This causes the trapezoidal plate 34 to press against the conveyor belt 3. At this time, the trapezoidal plate 34 receives a reaction force, which in turn exerts a force in the opposite direction on the two fixed columns 33. This pushes the sliding disc 32 to slide and compress the spring 31, allowing the spring 31 to store elastic potential energy. This energy, through the sliding disc 32, exerts a force in the opposite direction on the fixed columns 33, enabling the trapezoidal plate 34 to press against the conveyor belt 3, achieving a tight fit. At this point, the paint on the surface of the conveyor belt 3 can be cleaned, thus extending its service life.

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 make equivalent substitutions for some of the technical features.
