Description
Technical Field
[0001] The present application relates to the technical field of printing rollers, and in particular to a carbon fiber printing roller. Background Art
[0002] The printing roller is an important working part in a printing machine. It is generally made of wear-resistant metal materials such as steel. When in use, the printing roller needs to be installed on the mounting cylinder first, and then the mounting cylinder and the printing roller are driven to rotate by the driving device.
[0003] A Chinese patent with publication number CN219133535U discloses a printing roller, in which the roller and the core shaft are connected to form a printing roller as a whole through a positioning member. Therefore, when the printing pattern needs to be replaced, it is only necessary to separate the abutment block from the roller through the driving member, and then replace the roller, which effectively improves the replacement rate and reduces the printing cost.
[0004] However, when replacing a printing roller with a different pattern, the device needs to separate the entire roller from the core shaft, which makes the overall installation complicated, and when the surface of the printing roller is damaged, it is too expensive to replace the entire roller. Therefore, those skilled in the art provide a printing roller to solve the problems raised in the above background technology. Utility Model Content
[0005] In order to solve the problem of convenient replacement of printing rollers with different patterns and reduced replacement cost when the printing roller is damaged, the present application provides a carbon fiber printing roller.
[0006] The carbon fiber printing roller provided in this application adopts the following technical solution:
[0007] A carbon fiber printing roller comprises a positioning shaft, a rotating shaft is coaxially fixed at both ends of the positioning shaft, a carbon fiber printing roller body is coaxially fixed on the positioning shaft, the carbon fiber printing roller body comprises two semi-cylindrical bodies with semi-circular cross-sections, the two semi-cylindrical bodies wrap the positioning shaft and the end faces of the two semi-cylindrical bodies are smoothly abutted, a positioning groove is formed on the outer wall of the positioning shaft, a positioning rod inserted into the positioning groove is fixed on the inner wall of the semi-cylindrical body, and a fixing device is provided on the rotating shaft to prevent the semi-cylindrical body from detaching from the positioning shaft.
[0008] By adopting the above technical solution, when the carbon fiber printing roller body needs to be replaced, the worker can act on the fixing device to separate the fixing device from the semi-cylinder. At this time, it is convenient to take out the two semi-cylinders and replace them with new carbon fiber printing roller bodies. After the replacement, the fixing device is acted on again to fix the semi-cylinder.
[0009] Optionally, the fixing device includes an abutment ring sleeved on the rotating shaft, the abutment ring is slidably connected to the rotating shaft, the end face of the semi-cylinder is provided with a snap-in groove, the end of the abutment ring is fixed with a snap-in block inserted into the corresponding snap-in groove, and the fixing device also includes a fixing mechanism that presses the abutment ring against the semi-cylinder.

[0011] Optionally, the fixing mechanism includes a fixing ring which is threadedly connected to the rotating shaft and enables the abutment ring to press against the end surface of the semi-cylinder.
[0012] By adopting the above technical solution, the staff can rotate the fixing ring to move the fixing ring toward or away from the abutment ring, thereby facilitating the abutment ring to abut or separate from the semi-cylinder, thereby facilitating the installation and disassembly of the semi-cylinder.
[0013] Optionally, a limiting groove is provided on the outer wall of the rotating shaft along its axial direction, and a limiting block is fixed to the inner wall of the abutment ring so as to be slidably disposed in the limiting groove.
[0014] By adopting the above technical solution, the limiting block slides in the limiting groove to prevent the abutment ring from rotating relative to the rotating shaft, making it easier for the clamping block on the abutment ring to be inserted into the clamping groove of the semi-cylindrical body.
[0015] Optionally, the fixing mechanism includes a mounting ring fixed on a rotating shaft, a telescopic member is rotatably connected to the mounting ring, an abutment groove is provided at the end of the abutment ring, and after the telescopic member rotates, the end is clamped in the abutment groove and pushes the abutment ring to press against the semi-cylinder.
[0016] By adopting the above technical solution, during the process of replacing the semi-cylinder, the staff rotates the telescopic part to disengage the telescopic part from the abutment groove, which facilitates the abutment ring to move in the direction away from the semi-cylinder, thereby facilitating the removal of the semi-cylinder. After replacing the new semi-cylinder, the telescopic part is rotated to make the telescopic part abut against the abutment groove, thereby achieving the installation of the semi-cylinder.

During the disassembly process, it is only necessary to rotate the telescopic rod to disengage the telescopic rod from the abutment groove, which facilitates the disassembly of the semi-cylinder.
[0019] Optionally, an abutment bolt is threadedly connected to the telescopic tube, the abutment bolt is arranged radially along the telescopic tube, and an end of the abutment bolt abuts against a side wall of the telescopic rod.
[0020] By adopting the above technical solution, the abutment bolt can be used to fix the telescopic rod, reducing the possibility that the abutment ring cannot be tightly pressed against the semi-cylinder due to insufficient elasticity of the telescopic spring.
[0021] Optionally, the telescopic cylinder is rotatably connected to the mounting ring via a rotating shaft, and a torsion spring is sleeved on the rotating shaft of the telescopic cylinder to pull the telescopic cylinder to rotate toward the abutment ring.
[0022] By adopting the above technical solution, the provision of the torsion spring facilitates the rotation of the telescopic tube and the telescopic rod, thereby facilitating the telescopic rod to abut against the abutment ring.

[0024] When the carbon fiber printing roller body needs to be replaced, the worker can separate the abutment ring from the semi-cylinder body, which makes it convenient to take out the two semi-cylinder bodies and replace them with new carbon fiber printing roller bodies. After the replacement, the abutment ring is applied to make it tightly against the end surface of the semi-cylinder body to fix the semi-cylinder body.
[0025] The limiting block slides in the limiting groove to prevent the abutting ring from rotating relative to the rotating shaft, so as to facilitate the clamping block on the abutting ring to be inserted into the clamping groove of the semi-cylinder. BRIEF DESCRIPTION OF THE DRAWINGS

A positioning groove 5 is opened on the outer wall of the positioning shaft 1, and a positioning rod 6 is fixed on the inner wall of the semi-cylindrical body 4. The positioning rod 6 is inserted into the positioning groove 5, so that the positioning shaft 1 drives the semi-cylindrical body 4 to rotate synchronously.
[0036] Reference Figure 1 , Figure 2 and Figure 3 A fixing device is provided on the rotating shaft 2 to prevent the semi-cylindrical body 4 from separating from the positioning shaft 1. The fixing device includes an abutment ring 7 sleeved on the rotating shaft 2. The abutment ring 7 is slidably connected to the rotating shaft 2. A clamping groove 8 is provided on the end surface of the semi-cylindrical body 4. A clamping block 9 is fixed to the end of the abutment ring 7. The clamping block 9 is inserted into the corresponding clamping groove 8, so that the abutment ring 7 and the semi-cylindrical body 4 rotate synchronously. The fixing device also includes a fixing mechanism that makes the abutment ring 7 press against the semi-cylindrical body 4.
[0037] Reference Figure 1 , Figure 2 and Figure 3 The fixing mechanism includes a fixing ring 10 threadedly connected to the rotating shaft 2. By rotating the fixing ring 10, the fixing ring 10 moves along the axial direction of the rotating shaft 2. When the fixing ring 10 pushes the abutting ring 7 to press against the end surface of the semi-cylindrical body 4, the semi-cylindrical body 4 is fixed.
