Description

Technical Field

[0001] This application relates to the technical field of UV rollers, and in particular to a UV ink coating roller. Background Technology

[0002] UV ink coating rollers are specialized rollers used for coating UV inks. They exhibit excellent chemical stability with UV inks, preventing chemical reactions and avoiding issues such as corrosion, swelling, or softening of the roller rubber. UV ink coating rollers do not affect ink drying and curing: they do not hinder the drying or curing process of UV inks, allowing the ink to fully perform its functions and ensuring printing quality.

[0003] A search revealed Chinese Patent Publication No. CN 219073400 U, which discloses a UV ink coating roller, comprising a roller body, connecting rods, and a PU adhesive layer. Connecting rods are fixed to both ends of the roller body. A collar is fitted onto the surface of the roller body, and the collar surface is coated with a PU adhesive layer. A slider is fixed to the side of the collar that is in contact with the roller body surface, and each slider surface has a groove fixed to the outer wall of the roller body. Both ends of the slider are connected to the roller body via fixing components. This design eliminates the need to slowly peel the PU adhesive layer off the roller body surface after long-term use, improving the convenience of replacing the PU adhesive layer. A ball rolling within the groove reduces friction on the slider, facilitating its movement and improving stability.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following defects: In existing UV ink coating rollers, after prolonged use, the adhesive layer is difficult to remove from the central roller, and the connection between the central roller and the external power structure is not stable enough, affecting the performance of the UV ink coating roller during use. This results in a deterioration in the coating effect, requiring manual adjustment. Furthermore, gaps easily form between the adhesive layer and the central roller after prolonged rotation, making adjustment difficult and causing misalignment of the adhesive layer, thus affecting the normal use of the UV ink coating roller.

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses a UV ink coating roller. For example... Figure 1 As shown, it includes a main connecting rod 1. Two rotating hexagons 2, symmetrical about a central axis, are provided on the outer side of the main connecting rod 1 near the bearing ring 18. The rotating hexagons 2 are located on the outer side of the main connecting rod 1 to facilitate the rotational connection of the main connecting rod 1, allowing the main connecting rod 1 to accommodate more tools. The top and bottom positions of the outer side of the main connecting rod 1 are provided with grooves of the same thickness as the limiting vertical plate 17. The limiting vertical plate 17 slides inside the grooves, and the rotation angle of the main connecting rod 1 is limited by the limiting vertical plate 17.

[0024] Please see Figure 2A bearing ring 18 is rotatably mounted on one end of the main connecting rod 1. A secondary connecting rod 3 is rotatably mounted on the side of the bearing ring 18 away from the main connecting rod 1. Both sides of the outer circumference of the secondary connecting rod 3 are provided with sliding grooves. A limiting vertical plate 17 is slidably mounted on the inner wall of the sliding groove. The top of the limiting slide plate is fixedly mounted on the inner wall of the snap ring 16. The snap ring 16 is slidably sleeved on the outer side of the secondary connecting rod 3. The inner diameter of the snap ring 16 is larger than the diameter of the rotating hexagon 2. The secondary connecting rod 3 has the same diameter as the main connecting rod 1. The snap ring 16 slides on the surfaces of the secondary connecting rod 3 and the main connecting rod 1. The limiting vertical plate 17 slides on the inner wall of the sliding groove. The limiting vertical plate 17 and the outer snap ring 16 fix the main connecting rod 1 and the secondary connecting rod 3 into a whole, so that the main connecting rod 1 and the secondary connecting rod 3 can rotate simultaneously.

[0025] Please see Figure 3 A rotating sleeve 15 is fixedly installed at the end of the auxiliary connecting rod 3 away from the bearing ring 18. The inner wall of the rotating sleeve 15 is fixedly provided with an internal thread. The rotating sleeve 15 is sleeved on one end of the inner tube 14 through the internal thread to achieve closure of the right end of the inner tube 14. A vertical rod 4 is inserted into the middle of the rotating sleeve 15. The vertical rod 4 passes through the right end of the inner tube 14. The outer side of the rotating sleeve 15 is arranged in the same straight line as the outer side of the inner tube 14. The vertical rod 4 is inserted after the rotating sleeve 15 is sleeved on one end of the inner tube 14 to further limit the rotation of the rotating sleeve 15 and the inner tube 14. The inner tube 14 is threadedly inserted into the inner wall of the end of the rotating sleeve 15 away from the auxiliary connecting rod 3. A rubber layer circular plate 13 is slidably sleeved on the outer side of the inner tube 14.

[0026] Please see Figure 4 A lead screw 10 is rotatably mounted on one end of the inner wall of the inner tube 14. The threads at both ends of the lead screw 10 are arranged in opposite directions. By rotating the lead screw 10, the two threaded sliders 8 at both ends move simultaneously relative to each other or towards each other. The right end of the lead screw 10 is horizontally positioned with the end of the inner tube 14. The right end of the lead screw 10 is provided with an internal hexagonal groove, which facilitates rotation by means of a tool.

[0027] Please see Figure 2 and Figure 3Two threaded sliders 8 are threadedly connected to the threaded surface of the lead screw 10. Each threaded slider 8 is fixedly connected to both ends of an arc-shaped rod 6. The two threaded sliders 8 move simultaneously under the action of the lead screw 10, simultaneously driving the two outer arc-shaped rods 6 to move simultaneously. The arc-shaped rods 6 are located on both sides of the threaded sliders 8. Slide rods 11 are fixedly installed at the top and bottom of the threaded sliders 8. The top of the slide rod 11 slides onto the surface of a limiting crossbar 12. One end of the limiting crossbar 12 is fixedly installed on one end of the inner wall of the inner tube 14. Under the action of the threaded sliders 8, the slide rods 11 slide on the surface of the limiting crossbar 12, thereby limiting the movement of the threaded sliders 8 and preventing them from moving with the lead screw 10. The rotation generates a linkage rotation. A locking rod 7 is provided at the middle of the outer side of each of the two arc-shaped rods 6. Both locking rods 7 pass through both sides of the inner tube 14. The two symmetrical locking rods 7 engage with the inner walls of the two locking slots 9, achieving the locking effect on the adhesive layer circular plate 13. An arc-shaped rod 6 is fixedly provided at the middle of the front of the threaded slider 8. A locking rod 7 is fixedly provided at the outer side of the middle of the arc-shaped rod 6. The end of the locking rod 7 away from the arc-shaped rod 6 passes through the middle of the inner tube 14 and is fixedly engaged with the locking slot 9. The outer side of the locking slot 9 is fixedly connected to the inner wall of the adhesive layer circular plate 13. Sealing rings 5 ​​are fixedly provided at both ends of the inner wall of the adhesive layer circular plate 13. The inner wall of the sealing ring 5 is slidably connected to the outer side of the inner tube 14. The adhesive layer circular plate 13 contacts the inner tube 14 through the sealing ring 5, increasing the sealing effect inside the adhesive layer circular plate 13.

[0028] The implementation principle of a UV ink coating roller according to an embodiment of this application is as follows: A circular adhesive plate 13 to be used is fitted onto the outer surface of an inner tube 14, with one end of the circular adhesive plate 13 positioned at the left edge of the inner tube 14. Rotating the lead screw 10 causes the two threaded sliders 8 to rotate simultaneously. As the threaded sliders 8 move relative to each other, they compress the central arc-shaped rod 6, causing it to deform and push the central locking rod 7 towards the outer side of the inner tube 14. The locking rod 7 contacts the locking groove 9 on the inner side of the circular adhesive plate 13, thus securing the circular adhesive plate 13. At this time, rotating the outer... The rotating sleeve 15 on the side closes the right end of the inner tube 14. After the rotating sleeve 15 closes the inner tube 14, the vertical rod 4 is inserted into the middle of the rotating sleeve 15 to further fix the rotating sleeve 15. The main connecting rod 1 is connected to the power structure by rotating the hexagon 2 through a tool. After connection, the arc rod 6 is pushed in the direction of the main connecting rod 1. The internal locking rod 7 coincides with the sliding groove on the outside of the main connecting rod 1 to prevent the main connecting rod 1 from rotating. At the same time, the rotating hexagon 2 is closed by the locking ring 16, and the main connecting rod 1 and the auxiliary connecting rod 3 are connected into a whole to drive the entire rubber roller to rotate.

[0029] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
