Description

Technical Field

[0001] The utility model relates to the technical field of printing rollers, and particularly relates to a printing roller for paper printing. Background Technique

[0002] Printing is a technology that transfers the original content such as text, pictures, and photos to the surfaces of materials such as paper, fabrics, and leather through processes such as plate making, ink application, and pressing, and replicates the original content in batches. Among them, the printing roller is an important component.

[0003] In the prior art, after the rubber roller is used for a long time, the surface will age and form enamel, and it needs to be replaced. However, the existing printing roller assemblies are generally fixedly installed, and the disassembly and replacement of the rubber roller parts are relatively troublesome, and it is necessary to wait for a long time for shutdown, thus affecting the printing efficiency.

[0004] Therefore, a printing roller for paper printing is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a printing roller for paper printing to solve the problems mentioned in the above background technique.

[0006] The utility model specifically adopts the following technical solutions to achieve the above purpose:

[0007] A printing roller for paper printing includes a roller body and two mounting brackets. Both ends of the roller body are fixedly connected with rotating shafts. The end of the rotating shaft is rotatably connected with a positioning block, and the positioning block is movably inserted into the top of the mounting bracket. A printing rubber roller is sleeved on the surface of the roller body. A tightening assembly for limiting the printing rubber roller is arranged on the surface of the roller body. A clamping mechanism for limiting the positioning block is installed on the side of the mounting bracket. An auxiliary lifting assembly is also installed on the surface of the mounting bracket.

[0008] Further, the tightening assembly includes two arc-shaped clamping rings, and the rear ends of the arc-shaped clamping rings are hinged to each other. The front ends of both arc-shaped clamping rings are fixedly connected with mounting pieces, and a fastening bolt is threadedly connected between the two mounting pieces.

[0009] Further, the clamping mechanism includes a mounting box, and the mounting box is fixedly connected to the side of the mounting bracket. A double-headed screw is rotatably connected to the inner wall of the mounting box. A connecting rod is threadedly connected to the surface of the double-headed screw, and the connecting rod is movably inserted into the mounting box. A plug post is fixedly connected to the surface of the connecting rod. Plug holes are formed in the front and back of the positioning block, and the inner wall of the plug hole is movably inserted with the plug post. The clamping mechanism further includes an adjusting assembly for controlling the rotation of the double-headed screw.

[0010] Furthermore, the adjustment assembly includes a worm, and the worm is rotatably connected to the mounting box, the end of the worm is fixedly connected to a turntable, the middle of the double-headed screw is fixedly sleeved with a worm wheel, and the worm wheel is meshed with the worm.

[0011] Furthermore, the auxiliary lifting assembly includes an electric push rod, and the electric push rod is fixedly mounted on the surface of the mounting frame, the telescopic end of the electric push rod is fixedly connected to a support block, the bottom surface of the positioning block is provided with an alignment groove, and the inner wall of the alignment groove is movably connected to the end of the support block.

[0012] Furthermore, the front and back sides of the positioning block are both provided with sliding grooves, and the inner walls of the sliding grooves are movably engaged with the mounting frame.

[0013] The beneficial effects of the utility model are as follows:

[0014] The limit on the positioning block is released by the clamping mechanism, and the auxiliary lifting component is used to push the positioning block upward so that the positioning block is separated from the top of the mounting frame. At this time, the rotating shaft and the roller body can be disassembled, and then the limit on the printing rubber roller is released by the clamping component. The printing rubber roller can be quickly disassembled, replaced or cleaned, which makes it easy to quickly disassemble the printing roller. Compared with the existing technology, it is more convenient and efficient to replace or clean the printing roller, thereby shortening the downtime operation time and ensuring the overall printing efficiency.
