[0002] In the printing industry, printing cylinders are indispensable important components, which are widely used in fields such as plastic packaging and paper printing. Printing cylinders can be divided into those with rotating rollers and those in the form of rollers sleeved on a rotating shaft according to their structures, and they all rotate through a shaft body to achieve precise control during the printing process.

[0003] In traditional printing cylinder designs, especially for printing cylinders used in laser printing technology, the installation and replacement processes are often cumbersome. Installation usually involves multiple steps, such as disassembling fixing parts, adjusting positions, tightening screws, etc. This not only takes time and effort but also easily damages the printing cylinder, affecting its service life and printing quality. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the drawbacks in the prior art that installation usually involves multiple steps, such as disassembling fixing parts, adjusting positions, tightening screws, etc., which not only takes time and effort but also easily damages the printing cylinder, affecting its service life and printing quality, and to propose a laser printing cylinder that is convenient to replace.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A laser printing cylinder that is convenient to replace, comprising a roller barrel body;

[0007] An inner cylinder, serving as the shaft body of the roller barrel body, and the roller barrel body is slidably sleeved on the outer wall of the inner cylinder;

[0008] Two connecting pieces, used for installing the roller barrel body on the equipment, and the two connecting pieces are respectively located on both sides of the inner cylinder;

[0009] A driving assembly, used for driving the connecting pieces to move, the driving assembly is arranged at one end of the inner cylinder, and the driving assembly includes a twisting member.

[0010] In a possible design, an inner ring is fixedly arranged on one side of the inner cylinder close to the twisting member, an outer ring is fixedly sleeved on the side of the outer wall of the inner ring away from the inner cylinder, the twisting member includes an outer cylinder and two outer half-rings, a threaded ring is fixedly arranged on the inner wall of the outer cylinder, and one end of the outer wall of the threaded ring is matched with the inner wall of the inner ring. An inner half-ring is fixedly arranged on the inner wall of the outer half-ring, and a plurality of mounting holes are formed on the surfaces of both the outer cylinder and the outer half-ring.

[0011] In a possible design, the inner wall of the inner cylinder is arranged as a polygon, and two polygon blocks are slidably arranged on the inner wall of the inner cylinder. A rotating shaft is fixedly arranged at one end of the polygon block close to the connecting piece, the connecting piece is fixedly arranged at one end of the rotating shaft, and the inner wall of the threaded ring is in threaded cooperation with the outer wall of the rotating shaft.

[0012] In a possible design, round rods are fixedly arranged at the ends of the two polygon blocks close to each other. A spiral groove is formed on the outer wall of the round rod. A fixed block is fixedly arranged in the middle of the inner wall of the inner cylinder. A cylinder is rotatably arranged on the inner wall of the fixed block. Both round rods are located inside the cylinder. Limit rods are fixedly arranged on both sides of the inner wall of the cylinder.

[0016] In this application, during specific use, when the twisting part is rotated, since the rotating shaft can only slide, the rotating shaft is driven to move through threaded cooperation, so that the rotating shaft extends out or retracts into the inner cylinder. When the rotating shaft at one end of the twisting part moves, it will drive the round rod to move through the polygon block. At this time, since the cylinder is rotatably arranged and the limit rod on the inner wall of the cylinder is restricted by the spiral groove, when the round rod moves, the cylinder will be driven to rotate. The rotation of the cylinder will drive another round rod to displace through another limit rod, so as to drive the rotating shaft at the other end to perform the same movement, so that only by rotating the twisting part can the telescopic movement of the rotating shafts at both ends of the roller cylinder body be realized.

At this time, rotate the threaded cylinder and remove it, and the roller cylinder body can be extracted from the outer wall of the inner cylinder for replacement, or disconnect the connection between the connecting piece and the rotating shaft to replace the connecting piece. After the replacement is completed, directly place the plate roller and then rotate the twisting part to extend and connect the rotating shafts and the connecting pieces at both ends, which is simple and convenient.

[0017] In the present utility model, for the laser plate cylinder that is convenient to replace, through the driving assembly, it can be achieved that by rotating the twisting member, the rotating shafts at both ends together with the corresponding connecting members can be retracted into the interior of the inner cylinder, so that when the plate cylinder needs to be disassembled, after disconnecting the connection between the connecting member and the driving mechanism, rotating the twisting member can remove it for replacement operation, and both the roller barrel and the connecting member can be replaced;

[0018] In the present utility model, for the laser plate cylinder that is convenient to replace, through the threaded cylinder, it can be achieved that when the entire plate cylinder is removed by the driving assembly, when the roller barrel needs to be replaced, only by rotating the threaded cylinder to remove it, then the roller barrel can be drawn out and a new roller barrel can be installed, and then the threaded cylinder can be rotated and installed again;

[0019] In the present utility model, during use, after disconnecting the connection between the connecting member and the driving mechanism on the equipment, through the driving assembly, rotating the twisting member can retract the rotating shafts at both ends together with the corresponding connecting members into the interior of the inner cylinder, and then the whole can be taken out;

[0020] Rotating the threaded cylinder can remove it and draw out the roller barrel for replacement, and disconnecting the connection between the connecting member and the rotating shaft can perform the replacement. BRIEF DESCRIPTION OF THE DRAWINGS
