Description

Technical Field

[0001] This utility model relates to the field of paper tube roll coating technology, specifically a paper tube roll coating machine for uniform roll coating. Background Technology

[0002] As a core consumable in packaging, textiles, and building materials, the uniformity of the surface coating of paper tubes directly affects product performance (such as waterproofing and abrasion resistance) and appearance quality. Traditional manual coating suffers from problems such as uneven thickness and low efficiency, while roller coating technology achieves efficient and precise transfer of coatings through mechanical automation, becoming the mainstream process in paper tube processing.

[0003] However, existing roller coating machines, due to the fixed size of the rotating rollers, can only coat one type of paper tube at a time. When coating paper tubes of different sizes and lengths, it is necessary to change to rollers of different lengths, resulting in time and labor consumption for operators and affecting the coating efficiency of the machine. Therefore, to solve the above problems, we need to design a paper tube roller coating machine that can achieve uniform coating. Utility Model Content

During the roller coating process on paper tubes, the rollers rotate to apply the coating material, facilitating the roller coating operation. Furthermore, when roller coating is required for longer paper tubes, the connecting plate allows the rollers and the discharge box to move on the support, enabling roller coating of paper tubes of different lengths. Simultaneously, the rotation of the rollers at the discharge plate ensures that the coating material adheres evenly to the rollers when they are fully coated, resulting in uniform roller coating and facilitating the operation of the device.

Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Please see Figures 1-6 This utility model provides a paper tube roller coating machine for uniform roller coating, comprising:

[0028] The machine body 1 has a bracket 2 fixedly connected to it. A pair of connecting plates 3 are slidably connected in the inner groove of the bracket 2. A discharge plate 4 is fixedly connected to the connecting plate 3. A roller 6 is rotatably connected to the connecting plate 3. A first cylinder 9 is fixedly connected to the connecting plate 3. A discharge box 5 is provided on the first cylinder 9. Slide plates 20 are slidably connected to both sides of the machine body 1. A second cylinder 21 is rotatably connected to the slide plate 20 and fixedly connected to it. A movable block 22 is fixedly connected to the second cylinder 21. A rotating seat 25 is provided on the movable block 22.

[0029] Specifically, the worker places the paper tube at the rotating seat 25. The second cylinder 21 operates, causing the movable block 22 to move the rotating seat 25 to both sides of the hollow paper tube. The rotating seat 25 clamps and fixes the paper tube. The sliding plate 20 then moves the rotating seat 25 and the fixed paper tube to the roller 6 for roller coating. The first cylinder 9 moves downwards, causing the discharge box 5 to move, resulting in the discharge plate 4 moving within the bottom of the discharge box 5's inner cavity. This opens the discharge port at the bottom of the discharge box 5, allowing the coating in the discharge box 5 to slide down the discharge plate 4. Because the discharge plate 4 is in contact with the roller 6, the coating adheres to the roller. On the roller 6, when the paper tube is being coated, the roller 6 rotates to apply the coating material, thus facilitating the coating process. Furthermore, when coating longer paper tubes, the connecting plate 3 can move the roller 6 and the discharge box 5 on the support 2, facilitating the coating of paper tubes of different lengths. Simultaneously, the rotation of the roller 6 at the discharge plate 4 ensures that the coating material adheres evenly to the roller 6 when it is fully coated, resulting in uniform coating of the paper tube and facilitating the operation of the device.

[0030] Please see Figures 1-4 A sealing plate 8 is fixedly connected to the discharge plate 4, and the sealing plate 8 is movably connected to the discharge port at the bottom of the discharge box 5. A second motor 7 is fixedly connected to one side of the roller 6, and the second motor 7 is fixedly connected to a connecting plate 3. Side plates 14 are fixedly connected to both sides of the discharge box 5, and a distance sensor 15 is installed on the discharge box 5. A fixing plate 10 is fixedly connected to the first cylinder 9, a slide rod 12 is fixedly connected to the fixing plate 10, a spring 11 is fixedly connected to the fixing plate 10, a limit plate 13 is fixedly connected to the slide rod 12, the side plate 14 is slidably connected to the slide rod 12, and the other end of the spring 11 is fixedly connected to the side plate 14.

[0031] Specifically, in the initial state, the first cylinder 9 is in an extended state, causing the fixed plate 10 to move the discharge box 5 upward, so that the discharge port at the bottom of the discharge box 5 is in contact with the sealing plate 8 on the discharge plate 4. This seals the discharge port at the bottom of the discharge box 5 through the sealing plate 8, and the spring 11 is in a compressed state. When the paper tube needs to be coated by the roller 6, the first cylinder 9 moves the fixed plate 10 downward, the spring 11 is out of compression, and the discharge box 5 moves downward, so that the sealing plate 8 is no longer in contact with the discharge port at the bottom of the discharge box 5. This opens the discharge port at the bottom of the discharge box 5, allowing the paint in the discharge box 5 to slide down the discharge plate 4, coating the roller 6 with paint, and then being distributed by the second motor 7. The operation of the roller 6 allows it to rotate, enabling the coating to be applied to the roller 6 and facilitating the coating of the paper tube. Furthermore, by controlling the degree of downward movement of the first cylinder 9 when the discharge box 5 is lowered and opened, the amount of coating in the discharge box 5 can be controlled. Simultaneously, as the roller 6 rotates and picks up the coating, the discharge plate 4 scrapes the roller 6, controlling the amount of coating adhering to the roller 6. This ensures that the coating is evenly applied to the paper tube during the roller 6's rotation and coating process. The distance sensor 15 detects the length of the paper tube, ensuring that the roller 6 coats the paper tube precisely, preventing any uncoated portions from being coated and resulting in uneven coating.

[0032] Please see Figures 1-4 A first motor 16 is fixedly connected to one side of the machine body 1. A first lead screw 17 is fixedly connected to the first motor 16. A connecting plate 3 is threadedly connected to the first lead screw 17. The first lead screw 17 is rotatably connected to the inner groove of the bracket 2. A recycling box 33 is fixedly connected to the bottom of the machine body 1. Slide grooves 34 are provided on both side walls of the machine body 1. A control panel 35 is fixedly connected to one side of the machine body 1.

[0033] Specifically, the first motor 16 operates, causing the first lead screw 17 to rotate. Since the connecting plate 3 is threaded onto the first lead screw 17 and slides in the inner groove of the bracket, the device can perform roller coating on paper tubes of different sizes and lengths through the roller 6, improving the practicality of the device. When the device is working, the operator can control the device through the control panel 35. By placing the recycling box 33 at the bottom of the roller 6, the dripping paint can be recycled when the roller 6 is coated.

[0034] Please see Figures 1-6A third motor 18 is fixedly connected to both sides of the machine body 1. A second lead screw 19 is fixedly connected to the third motor 18. The second lead screw 19 is rotatably connected to the slide groove 34. The slide plate 20 is threadedly connected to the second lead screw 19. A fourth motor 23 is fixedly connected to the movable block 22. A positioning plate 24 is fixedly connected to the fourth motor 23. A rotating seat 25 is fixedly connected to the other side of the positioning plate 24. The rotating seat 25 is provided with a movable groove 36 and a telescopic groove 37.

[0035] Specifically, the operator places the paper tube at the rotating seat 25 and operates the second cylinder 21, causing the movable block 22 to move the rotating seat 25 to both sides of the hollow paper tube, so that the two side walls of the paper tube are in contact with the positioning plate 24. The rotating seat 25 can clamp and fix the paper tube. The third motor 18 operates, causing the second lead screw 19 to rotate. Since the sliding plate 20 slides in the slide groove 34 and is slidably connected to the second lead screw 19, the sliding plate 20 can move the rotating seat 25 and the paper tube to the roller 6 to perform roller coating on the paper tube. Furthermore, during roller coating, the fourth motor 23 operates, causing the positioning plate 24 to drive the rotating seat 25 to rotate, which can drive the paper tube to rotate, facilitating roller coating on other parts of the paper tube and making the coating even.

[0036] Please see Figures 1-6 A fifth motor 26 is fixedly connected to the rotating seat 25. A third lead screw 27 is fixedly connected to the fifth motor 26. The third lead screw 27 is rotatably connected to the movable groove 36. A pair of sliders 28 are threadedly connected to the third lead screw 27. The sliders 28 are slidably connected to the movable groove 36. A joint 29 is rotatably connected to the sliders 28. A push plate 30 is slidably connected to the telescopic groove 37. One side of the push plate 30 is rotatably connected to the joint 29. A clamping plate 31 is fixedly connected to the other side of the push plate 30. An anti-slip strip 32 is provided on the clamping plate 31.

[0037] Specifically, when the positioning plate 24 is in contact with the two side walls of the paper tube, the fifth motor 26 operates, causing the third lead screw 27 to rotate. Since the third lead screw 27 is a bidirectional lead screw, and a pair of sliders 28 are threadedly connected to the third lead screw 27, the sliders 28 are slidably connected in the movable groove 36, allowing the sliders 28 to slide on the third lead screw 27, driving the joint 29 to move, which can push the push plate 30 to move on the telescopic groove 27, so that the clamping plate 31 is in contact with the inner wall of the paper tube, thereby fixing the paper tube through the clamping plate 31. Furthermore, the rubber anti-slip strip 32 can increase the friction between the clamping plate 31 and the inner wall of the paper tube, so that when the fourth motor 23 drives the rotating seat 25 to rotate, it can drive the paper tube to rotate, so that the roller 6 performs the roller coating work on the paper tube.

[0038] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
