Abstract
Description
Technical Field
[0001] This utility model relates to the field of coating roller technology, and more specifically, to a coating roller assembly. Background Technology
[0002] Currently, coating roller assemblies are widely used in printing, packaging, textile, papermaking and other industries. Their main function is to uniformly coat the surface of various objects with fluid materials such as paints, adhesives and inks, providing protection, decoration or special functions. A typical coating roller assembly usually consists of a roller core, a rubber sleeve, and a mounting shaft. The roller core provides structural support for the roller and is mostly made of metal. The rubber sleeve covers the outer surface of the roller core and is generally made of materials such as rubber and polyurethane. It is in direct contact with the paint and the material being coated and is the key part to achieve uniform coating. The mounting shaft is used to install the roller onto the equipment so that it can rotate.
[0003] However, in actual use, as the usage time increases, the rubber sleeve on the outer surface of the coating roller will inevitably experience problems such as wear, deformation and oxidation. To ensure coating quality and production efficiency, timely replacement of the rubber sleeve is necessary. However, the existing coating rollers' rubber sleeves and roller cores are mostly tightly bonded together through processes such as vulcanization and hot pressing, forming a near-integral structure. This makes sleeve replacement extremely difficult. On the one hand, due to the tight bond, there is a lack of effective separation methods during disassembly. Workers often need to use complex and destructive tools, such as cutting equipment and chisels, to forcibly peel the rubber sleeve from the roller core. This not only consumes a lot of manpower and time but also easily damages the roller core surface. Once the roller core is damaged, even if a new rubber sleeve is replaced, it is difficult to guarantee the coating accuracy of the roller, and it may even lead to the scrapping of the entire roller, resulting in resource waste. On the other hand, the rubber sleeve replacement operation is difficult and requires professional technicians, which places high demands on the company's personnel skills and increases labor costs. In addition, the difficulty in replacing the rubber sleeve leads to a significant increase in equipment downtime, seriously affecting the production schedule, reducing the company's production efficiency, and thus adversely affecting the company's economic benefits. Therefore, improvements are needed. Utility Model Content

[0022] 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.
[0023] like Figures 1 to 5 As shown, this utility model provides a coating roller assembly, comprising:
[0024] Roller core 1, short groove 2 is provided on the outer surface of roller core 1, stop block 12 is fixedly installed inside short groove 2, connecting sleeve 3 is movably sleeved on the outer surface of roller core 1, slot 4 is provided inside connecting sleeve 3, rubber sleeve 5 is fixedly sleeved on the outer surface of connecting sleeve 3.
[0025] The locking mechanism is located inside the roller core 1;
[0026] The locking mechanism includes a long shaft 6, the outer surface of which is movably sleeved with the inside of the roller core 1. The outer surface of the long shaft 6 located inside the short groove 2 is provided with a threaded part 7. A toothed block 8 is threadedly sleeved on the outer surface of the threaded part 7. The outer surface of the toothed block 8 is slidably connected with the inside of the short groove 2. A first gear 9 is meshed with the top of the toothed block 8. A rotating block 10 is fixedly installed on the outer surface of the first gear 9. The outer surface of the rotating block 10 is movably connected with the inside of the slot 4. A round shaft 11 is fixedly sleeved inside both the first gear 9 and the rotating block 10. Both ends of the round shaft 11 are movably sleeved with the inside of the short groove 2.
[0027] When the long shaft 6 drives the threaded part 7 to rotate, the toothed block 8 will move back and forth along the inside of the short groove 2. When the toothed block 8 moves backward, it will drive the rotating block 10 to rotate around the circular shaft 11 through the first gear 9. Then the outer surface of the rotating block 10 will contact the stop block 12 during rotation. At this time, the rotating block 10 will be in a state of being completely retracted into the short groove 2. At this time, the rotating block 10 will not be able to lock the entire connecting sleeve 3, so that the operator can remove the entire connecting sleeve 3 from the outer surface of the roller core 1. When the toothed block 8 moves forward, the rotating block 10 will rotate in the opposite direction. When the outer surface of the rotating block 10 is in contact with the inside of the slot 4 during rotation, the rotating block 10 will lock the entire connecting sleeve 3, so as to achieve the effect of convenient disassembly and assembly of the entire connecting sleeve 3.
[0028] Among them, a fixing ring 13 is fixedly sleeved on the outer surface of the roller core 1, a toothed ring 14 is movably sleeved inside the fixing ring 13, and a handle 15 is fixedly installed on the outer surface of the toothed ring 14.
[0029] Because the toothed ring 14 is internally and movably connected to the fixed ring 13, the toothed ring 14 can rotate along the inside of the fixed ring 13. Due to the design of the handle 15, the operator can rotate the toothed ring 14 inside the fixed ring 13 by shaking the handle 15.
[0030] The toothed ring 14 is internally connected to a second gear 16, and the interior of the second gear 16 is fixedly sleeved with the front end of the long shaft 6.
[0031] Since the gear ring 14 meshes with the second gear 16, when the gear ring 14 rotates, it will drive the long shaft 6 to rotate through the second gear 16.
[0032] The outer surface of the roller core 1 is fixedly mounted with a positioning block 17, the outer surface of the positioning block 17 is slidably connected to the inside of the connecting sleeve 3, and a retaining ring 18 is fixedly sleeved behind the outer surface of the roller core 1, the front of the retaining ring 18 is in contact with the back of the connecting sleeve 3.
[0033] Due to the design of the positioning block 17 and the retaining ring 18, the assembly between the roller core 1 and the connecting sleeve 3 will have a good positioning effect.
[0034] Among them, a fixing block 19 is fixedly installed on the outer surface of the roller core 1, a square block 20 is fixedly installed on the outer surface of the fixing block 19, a lever 21 is slidably connected inside the square block 20, an insert rod 22 is fixedly installed on the back of the lever 21, and the rear end of the insert rod 22 is inserted into the inside of the front of the toothed ring 14.
[0035] When the insert rod 22 is inserted into the toothed ring 14, it will block the rotation of the toothed ring 14. Since the outer surface of the paddle 21 is slidably connected to the inside of the square block 20, the paddle 21 can move back and forth along the inside of the square block 20. When the paddle 21 moves forward along the inside of the square block 20, it will drive the insert rod 22 to move forward. At this time, the insert rod 22 will disengage from the toothed ring 14 during the forward movement, thereby releasing the blocking effect on the toothed ring 14.
[0036] Among them, a spring 23 is fixedly installed on the front of the paddle 21, and the front end of the spring 23 is fixedly connected to the inside of the square block 20.
[0037] When the paddle 21 moves forward along the inside of the square block 20, it will compress the spring 23. Due to the design of the spring 23, it will have a good restoring effect on the overall movement of the paddle 21.
[0038] Working principle and usage process of this utility model:
[0039] When the rubber sleeve 5 shows signs of aging such as wear, deformation, and oxidation after prolonged use, the operator needs to replace it. At this time, the operator moves the lever 21 forward along the interior of the square block 20. During this process, the spring 23 is compressed by the lever 21. Simultaneously, the insertion rod 22 moves forward driven by the lever 21. Then, the rear end of the insertion rod 22 contacts the insertion point inside the gear ring 14 during its backward movement. At this point, the insertion rod 22 can no longer lock the gear ring 14. The operator then pulls the handle 15, causing the handle 15 to rotate the gear ring 14 along the interior of the fixed ring 13. Since the interior of the gear ring 14 meshes with the outer surface of the second gear 16, when the gear ring 14 rotates, it simultaneously drives all four second gears 16 to rotate. At this time, the four long shafts 6, driven by the four second gears 16, move inside the roller core 1. As the roller rotates, the four sets of threaded parts 7 will rotate under the drive of the four long shafts 6. Since the outer surface of the threaded part 7 is engaged with the inner thread of the tooth block 8, when the four sets of threaded parts 7 rotate, they will drive the four sets of tooth blocks 8 to move backward along the inside of the four sets of short grooves 2. Since the outer surface of the tooth block 8 is meshed with the outer surface of the first gear 9, when the four sets of tooth blocks 8 move backward, they will drive the four sets of first gears 9 to rotate around the four sets of round shafts 11. At the same time, the four sets of rotating blocks 10 will rotate under the drive of the four sets of first gears 9. Then, the outer surface of the four sets of rotating blocks 10 will contact the four sets of stop blocks 12 during rotation. At this time, the rotating blocks 10 will retract into the inside of the short groove 2. Due to the design of the stop blocks 12, the rotation stroke of the rotating blocks 10 can be limited. At this time, the rotating blocks 10 will completely release the locking effect on the entire connecting sleeve 3, so that the operator can pull the entire connecting sleeve 3 out from the outer surface of the roller core 1.
[0040] The operator then needs to place the new connecting sleeve 3 onto the outer surface of the roller core 1. During this process, the operator needs to align the sliding groove inside the connecting sleeve 3 with the positioning block 17, and then push the connecting sleeve 3 as a whole, so that the connecting sleeve 3 moves backward along the outer surface of the short groove 2. When the rear end of the connecting sleeve 3 contacts the front of the retaining ring 18, the pushing of the connecting sleeve 3 is stopped. At this time, the inside of the four sets of slots 4 will be aligned with the inside of the four sets of short grooves 2. Due to the design of the positioning block 17 and the retaining ring 18, a good positioning effect will be achieved for the assembly of the roller core 1 and the connecting sleeve 3. Next, the operator drives the toothed ring 14 to rotate in the opposite direction by using the handle 15. At this time, the four sets of toothed blocks 8 will move forward along the inside of the four sets of short grooves 2. During the process, the four sets of first gears 9 will drive the four sets of rotating blocks 10 to rotate in the opposite direction. When the outer surfaces of the four sets of rotating blocks 10 are engaged in the slot 4 during rotation, the four sets of rotating blocks 10 will lock the entire connecting sleeve 3, so that the short slot 2 and the connecting sleeve 3 are assembled, thereby realizing the function of convenient assembly and disassembly of the entire connecting sleeve 3. When the rotating block 10 is engaged in the slot 4, the rear end of the spring 23 will be aligned with the slot on the front of the toothed ring 14. If the operator releases the lever 21, due to the elastic force of the spring 23, the spring 23 can drive the insert rod 22 to return to its original position through the lever 21, so that the insert rod 22 is re-inserted into the interior of the front of the toothed ring 14, thereby achieving the locking effect of the toothed ring 14.
