Technical Field

[0001] The utility model relates to the technical field of rubber roller assembly and disassembly, in particular to a polyurethane rubber roller. Background Art

[0002] Polyurethane rubber rollers are commonly used components in the paper printing industry. Their main function in offset printing machines is to transfer ink to ensure the normal printing of paper. However, polyurethane rubber rollers will naturally hydrolyze over time and have poor durability.

[0003] However, the existing polyurethane rubber roller requires multiple bolts to be disassembled before the polyurethane rubber roller can be removed, and replacing a new polyurethane rubber roller requires repeatedly installing multiple bolts again, which makes the replacement of the polyurethane rubber roller relatively cumbersome and inconvenient, affecting the production of the device; therefore, a polyurethane rubber roller is proposed to address the above problems.

[0022] Specific examples are given below.

[0023] See also Figure 1-5 As shown, a polyurethane rubber roller comprises a support plate 1, wherein the inner side of the support plate 1 is fixedly connected to a first motor 2, the output end of the first motor 2 is fixedly connected to a first pulley 3, the outer side of the first pulley 3 is rotatably connected to a belt 4, the inner side of the support plate 1 is rotatably connected to a second pulley 5, and the second pulley 5 and the belt 4 are rotatably connected on one side, the outer side of the support plate 1 is fixedly connected to a second motor 6, the output end of the second motor 6 is fixedly connected to a positive and negative screw rod 7, the positive and negative screw rod 7 and the support plate 1 are rotatably connected, the outer side of the positive and negative screw rod 7 is threadedly connected to a movable plate 8, the outer side of the movable plate 8 is rotatably connected to an insertion rod 9, the outer side of the insertion rod 9 is rotatably connected to a polyurethane rubber roller body 10, the insertion rod 9 is slidably connected to the second pulley 5, the outer side of the insertion rod 9 is fixedly connected to a reinforcement plate 11, and the reinforcement plate 11 and the polyurethane rubber roller body 10 is used in conjunction with each other. This step is achieved by setting a first motor 2, positive and negative screw rods 7, moving plate 8, insertion rod 9 and polyurethane rubber roller body 10. When the polyurethane rubber roller body 10 needs to be loaded and unloaded, the positive and negative screw rods 7 can be driven to rotate by the second motor 6, so that the positive and negative screw rods 7 drive the moving plate 8 to move, and the insertion rod 9 is driven to be pulled out from the inner side of the polyurethane rubber roller body 10 by the moving plate 8. At the same time, the reinforcement plate 11 is driven away from the polyurethane rubber roller body 10 by the insertion rod 9, and then the polyurethane rubber roller body 10 is removed, so that it is only necessary to start the second motor 6 for disassembly, thereby eliminating the need to manually disassemble and assemble multiple bolts repeatedly, and after installation, the insertion rod 9 is inserted into the inner side of the polyurethane rubber roller body 10, and the reinforcement plate 11 is close to the outer side of the polyurethane rubber roller body 10, so that the polyurethane rubber roller body 10 can rotate stably after installation, thereby improving the convenience of loading and unloading of the device and the stability of use.

[0024] Further, such as Figure 3 and Figure 4 As shown, the outer side of the polyurethane rubber roller body 10 is fixedly connected to a movable tooth plate 12, and the outer side of the reinforcement plate 11 is rotatably connected to a flat gear 13, and the flat gear 13 is meshed with the movable tooth plate 12, and the outer side of the flat gear 13 is fixedly connected to a movable screw rod 14, and the outer side of the movable screw rod 14 is threadedly connected to a stabilizing plate 15, and the stabilizing plate 15 is used in conjunction with the polyurethane rubber roller body 10.
