Description

Technical Field

[0001] This utility model belongs to the field of furniture manufacturing technology, specifically, it relates to a UV roller coating equipment. Background Technology

[0002] With the advancement of science and technology and the development of industry, surface treatment technology plays an increasingly important role in various fields. Roller-coated UV varnish, as an efficient and environmentally friendly surface treatment technology, plays an indispensable role in practical industrial applications. In the furniture manufacturing industry, roller-coated UV varnish can improve the gloss and wear resistance of furniture surfaces, making them more beautiful and durable.

[0003] The prior art discloses a UV paint roller coating device for door frame panels (CN217747758U), which includes a conveyor belt, a first coating roller, and a second coating roller. The conveyor belt is mounted on the conveyor roller, and the door frame panel is placed on the conveyor belt and moved forward by the conveyor belt. The first coating roller is located above the conveyor belt, and the second coating rollers are located on both sides of the conveyor belt. The first coating roller is connected to a first feed pipe and is mounted on a height adjustment bracket, and the second coating roller is connected to a second feed pipe and is mounted on a spacing adjustment bracket. This device can adjust the position of the coating rollers and can also take into account the coating of the side of the panel to meet the coating requirements of door frame panels of different thicknesses. In addition, the device also optimizes the UV paint feeding system to ensure that the device can coat the UV paint more evenly and ensure the final coating quality.

[0004] Research revealed that the device uses a spacing adjustment component to roll-coat both sides of furniture boards. This method relies on the characteristics of a flexible hose for spacing adjustment, but the hose's material has limitations, making it prone to damage and unsuitable for long-term use. Furthermore, the lack of pre-cleaning of the furniture boards means that surface dust is fixed during the coating process, resulting in poor hygiene and affecting aesthetics. Moreover, because furniture boards vary in thickness, shape, and size, the connecting hose used in this device cannot adapt to different board thicknesses and shapes. This leads to uneven coating on both sides of boards of varying shapes and thicknesses, requiring manual recoating.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A UV roller coating device includes a base plate with two supports symmetrically arranged above it. The base plate is fixedly connected to the supports. A height adaptation component and a spacing adjustment component are arranged between the two supports. The height adaptation component includes a slider, a positioning block, and a paint tank. Multiple height adaptation components are provided. The spacing adjustment component includes a positive and negative lead screw, a slide rod, a spring, and a handle. The positive and negative lead screw is rotatably connected to the support, the slide rod is fixedly connected to the support, a spring is fixedly arranged between the slide rod and the corresponding slider, the slider is slidably connected to the support, the positioning block is rotatably connected to the paint tank, and the positioning block is movably connected to the slider.

[0008] In a preferred embodiment of this utility model, a baffle is fixedly connected between the two brackets, and a sliding groove is provided on the inner side of the top of the bracket. The bracket is slidably connected to the slider through the sliding groove, and a protrusion corresponding to the sliding groove is provided on the top of the slider. The protrusion engages with the sliding groove.

[0009] In a preferred embodiment of this utility model, one of the brackets is rotatably connected to the positive and negative lead screws via a baffle, and the other bracket is fixedly connected to the slide rod via a baffle. The positive and negative lead screws and the slide rod are symmetrically arranged at both ends of the baffle. The two ends of the positive and negative lead screws are respectively threaded with different sliders, and the two ends of the slide rod are respectively slidably engaged with other sliders.

[0010] In a preferred embodiment of this utility model, a locking groove is provided inside the bottom end of the slider, and a locking block is rotatably connected to the side of the paint tank near the slider. The locking block slides in the locking groove, and the slider locks the locking block by locking the locking groove.

[0011] In a preferred embodiment of this utility model, a coating roller is snapped into the bottom of the paint tank, the coating roller is rotatably connected to the paint tank, and the coating roller is located on the adjacent side of the locking block.

[0012] In a preferred embodiment of this utility model, two positioning columns are symmetrically fixed on one side of one of the brackets, and the slide rod is fixedly disposed between the two positioning columns. The sliders at both ends of the slide rod are fixedly disposed on fixed shafts, and limit hooks are rotatably connected to the fixed shafts through bearings. The limit hooks engage with the positioning columns.

[0013] In a preferred embodiment of this utility model, a spring is fixedly installed between the sliders at both ends of the slide rod and the bracket. The springs are sleeved on both ends of the slide rod, and the sliders are elastically connected to the bracket through the springs.

[0014] In a preferred embodiment of this utility model, one end of the positive and negative lead screw is fixedly connected to a handle, and both ends of the positive and negative lead screw and both ends of the slide rod are respectively provided with a height adaptation component on one side.

[0015] In a preferred embodiment of the present invention, a cleaning brush is rotatably connected between the two brackets, and a motor is provided on one side of one of the brackets, with the output end of the motor connected to one end of the cleaning brush.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. The spacing condition component can adapt to the width of the plate, while the cooperation between the limit hook, positioning post, slide bar and spring can make the device adapt to the shape of both sides of the plate. Furthermore, due to the presence of the paint tank and feed pipe, the limitations caused by the hose material can be effectively avoided, thus ensuring the long-term use of the device.

[0018] 2. The cleaning brush itself is made of a flexible material with good extensibility. No matter how thick the board is, when the board passes through the cleaning brush, the dust on its surface will be cleaned by squeezing or contacting the cleaning brush. This not only keeps the surface of the board clean, but also avoids the dust from being fixed during the roller coating process, thus ensuring the aesthetic effect of the board in the later stage.

[0019] 3. Measure the thickness of the board by using the position of the coating roller, and then rotate the positioning block to select a suitable position in the positioning groove. This helps the paint box control its height with the help of the positioning block, thereby adapting to the thickness of the board. Selectively release the limiting hook according to the shape of the board to ensure that both sides of the board are evenly coated by roller, avoiding the possibility of insufficient coating due to manual secondary coating.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0031] A UV roller coating device, such as Figure 1 , Figure 3 and Figure 4 As shown, the system includes a base plate 10, with two symmetrical supports 11 arranged above the base plate 10. The base plate 10 is fixedly connected to the supports 11. A height adaptation component and a spacing adjustment component are arranged between the two supports 11. The height adaptation component includes a slider 14, a locking block 16, and a paint tank 17. Multiple height adaptation components are provided. The spacing adjustment component includes a positive and negative lead screw 19, a slide rod 20, a spring 21, and a handle 22. The positive and negative lead screw 19 is rotatably connected to the support 11. The slide rod 20 is fixedly connected to the support 11. A spring 21 is fixedly arranged between the slide rod 20 and the corresponding slider 14. The slider 14 is slidably connected to the support 11. The locking block 16 is rotatably connected to the paint tank 17. The locking block 16 is movably connected to the slider 14.

[0032] The working principle is as follows: the spacing adjustment component is used to adapt to the width of the board, the height adjustment component is used to adapt to the height of the board, the position of the paint box 17 is adjusted according to the thickness of the board, and the locking block 16 is used to lock the slider 14 to control the height of the paint box 17. When the handle 22 is rotated, it drives the positive and negative screws 19 to rotate. The sliders 14 at both ends of the positive and negative screws 19 will converge and slide in the corresponding brackets 11, thereby driving the corresponding paint box 17 to move closer to both sides of the board to apply paint.

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, a baffle 13 is fixedly connected between the two brackets 11. A sliding groove 12 is provided on the inner side of the top of the bracket 11. The bracket 11 is slidably connected to the slider 14 through the sliding groove 12. The slider 14 is engaged with the sliding groove 12. A protrusion corresponding to the sliding groove 12 is provided on the top of the slider 14. The protrusion is engaged with the sliding groove 12.

[0034] The working principle is as follows: the bracket 11 has a U-shaped structure, the sliding groove is located on the inner bottom surface of the bracket 11, the cross-sectional shape of the sliding groove 12 is trapezoidal, the slider 14 has an L-shaped structure, the protrusion and the sliding groove 12 are both trapezoidal, the slider 14 is slidably connected to the sliding groove 12 by means of the protrusion, and at the same time the sliding groove 12 and the protrusion are engaged by means of the trapezoidal shape.

[0035] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, one bracket 11 is rotatably connected to the positive and negative lead screws 19 via a baffle 13, and the other bracket 11 is fixedly connected to the slide rod 20 via a baffle 13. The positive and negative lead screws 19 and the slide rod 20 are symmetrically arranged at both ends of the baffle 13. Different sliders 14 are threaded onto both ends of the positive and negative lead screws 19, and other sliders 14 are slidably engaged at both ends of the slide rod 20. Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, one of the brackets 11 has two symmetrically fixed positioning posts 27 on one side. A slide rod 20 is fixedly positioned between the two positioning posts 27. The sliders 14 at both ends of the slide rod 20 are each fixedly mounted with a fixed shaft 26. A limit hook 25 is rotatably connected to the fixed shaft 26 via a bearing, and the limit hook 25 engages with the positioning posts 27. Figure 2 , Figure 3 and Figure 4 As shown, a spring 21 is fixedly installed between the slider 14 at both ends of the slide rod 20 and the bracket 11. The spring 21 is sleeved on both ends of the slide rod 20, and the slider 14 is elastically connected to the bracket 11 through the spring 21; Figure 4 As shown, one end of the positive and negative lead screw 19 is fixedly connected to the handle 22, and both ends of the positive and negative lead screw 19 and both ends of the slide bar 20 are respectively provided with a height adaptation component on one side.

[0036] The working principle is as follows: A baffle 13 is fixedly connected between two supports 11. One end of the baffle 13 has a rotating hole with a bearing inside. The rotating hole is rotatably connected to the positive and negative lead screws 19 via the bearing. The slider 14 has a threaded hole inside and is threadedly connected to both ends of the positive and negative lead screws 19 via the threaded hole. Since there are at least four height adaptation components, the four sets of height adaptation components are located at both ends of the positive and negative lead screws 19 and the slider 20. The top of the paint tank 17 is equipped with a feed pipe for feeding, and the bottom of the paint pipe 17 is equipped with a connecting pipe with a seepage hole. When using the device, turning the handle 22 drives the positive and negative lead screws 19 to start rotating. At this time, the sliders 14 located at both ends of the positive and negative lead screws 19 will move due to the thread. The sliders 14 at both ends will continuously contract from the outside to the inside or expand from the inside to the outside. At this time, the spacing condition component can adapt to the width of the board, and because of the coating... The presence of the material box 17 and the feed pipe can effectively avoid the limitations caused by the material of the hose, thus ensuring the long-term use of the device. At the same time, in the initial state, the positioning post 27 and the limiting hook 25 are locked together, and the corresponding spring 21 is in a compressed state. Depending on the shape of the plate, if the plate is irregular, the restriction between the limiting hook 25 and the positioning post 27 is released. At this time, the spring 21 rebounds, and the two sliders 14 on the positive and negative screw 19 are moved to the inner sides of the bracket 11. When the irregular plate passes between the corresponding sliders 14 at both ends of the slide rod 20, the two sliders 14 adapt to the shape of the plate and move on the slide rod 20. With the elastic cooperation of the spring 21, the irregular plate passes through the corresponding coating rollers 18 at both ends of the slide rod 20. At the same time, the two coating rollers 18 continuously adhere to the side of the plate to adapt to the shape of the plate, thus ensuring the contact movement between the coating rollers 18 and the side of the plate.

[0037] like Figure 3 As shown, a locking groove 15 is provided inside the bottom end of the slider 14. The paint tank 17 is rotatably connected to the locking block 16 on the side near the slider 14. The locking block 16 slides within the locking groove 15, and the slider 14 locks the locking block 16 in place through the locking groove 15. Figure 3 As shown, a coating roller 18 is snapped into the bottom of the paint tank 17. The coating roller 18 is rotatably connected to the paint tank 17 and is located on the adjacent side of the locking block 16.

[0038] The working principle is as follows: the locking groove 15 penetrates the interior of the slider 14. The locking groove 15 includes two parts. The first part is located on the side near the paint tank 17 and is a square slide. The second part is located on the side away from the paint tank 17 and is a wavy circular locking groove. A square block is fixedly connected to the side of the paint tank 17 near the slider 14. The square block slides within the square slide. A circular groove is provided on the side of the square block away from the paint tank 17. A collar, which functions similarly to a bearing, is installed in the circular groove. A cylinder is rotatably connected to the circular groove via the collar. The length of the cylinder is longer than the width of the square slide. A locking block 16 is fixedly connected to the side of the cylinder away from the square block. The locking block 16 is rotatably connected to the cylinder via the cylinder. The paint box 17 has a width of 16 that is smaller than the square slide rail. In the vertical position, the 16 can slide within the square slide rail and the wavy circular groove. The length of the 16 is smaller than the maximum diameter of the wavy circular groove, so the 16 can rotate within the wavy circular groove in the horizontal position. It also uses the circular opening of the wavy circular groove for locking and limiting. The thickness of the board is measured by the position of the coating roller 18. Then, by rotating the 16, the 16 is positioned within the slot 15 to select a suitable position. This helps the paint box 17 control its height to adapt to the thickness of the board, ensuring uniform coating on both sides of the board and avoiding the possibility of insufficient coating due to manual secondary processes.

[0039] like Figure 5 , Figure 6 and Figure 7 As shown, a cleaning brush 23 is rotatably connected between two brackets 11. A motor 24 is provided on one side of one of the brackets 11, and the output end of the motor 24 is connected to one end of the cleaning brush 23.

[0040] The working principle is as follows: two brackets 11 are respectively fixedly connected to different square plates on the same side. One square plate has a rotating groove inside, and the other square plate has a round hole inside. The same rotating shaft is set in the rotating groove and the round hole. A cleaning brush 23 is fixedly connected to the curved surface of the shaft. When in use, the motor 24 is started. The shaft rotates and drives the cleaning brush 23 to rotate. Since the cleaning brush 23 is located at a low position and the cleaning brush 23 itself is made of a flexible material with good ductility, no matter how thick the board is, when the board passes through the cleaning brush 23, it will clean the dust on its surface by squeezing or contacting the cleaning brush 23. This not only keeps the surface of the board clean, but also avoids the possibility of dust being fixed in the roller coating, thereby ensuring the aesthetic effect of the board in the later stage.
