Abstract

The utility model provides a wear-resistant rubber covered roller for a printing machine, relates to the technical field of rubber covered rollers for printing machines, and solves the problems that printing parts outside the rubber covered roller can be replaced in order to ensure the printing quality, but the printing parts of a common rubber covered roller are difficult to replace. In the prior art, the rubber roller generally does not have a good stable structure to assist the connection stability between the rubber roller and a printing part, so that the printing quality is influenced due to looseness between the printing part and the rubber roller. A wear-resistant rubber roller for a printing machine comprises a connecting shaft, a rubber roller and a rubber roller body, fixed side seats are symmetrically and fixedly mounted at the two ends of the connecting shaft; after the connecting sleeve is replaced, an operator only needs to rotate the knob to drive the limiting screw rod to rotate and push the limiting sliding block to move until the limiting teeth at the bottom of the limiting screw rod are completely clamped with the limiting teeth on the limiting block of the rubber roller main shaft, so that the fixed side seat is effectively prevented from loosening due to vibration or external force, and the long-term stability of the connecting sleeve is ensured.

Description

TECHNICAL FIELD

[0001] The utility model belongs to printing machine rubber roller technical field, more specifically, especially relate to a wear -resisting rubber roller for printing machine. BACKGROUND

[0002] As the core component of the printing machine, the rubber roller can uniformly adsorb and transfer ink to the printing plate, ensuring that the printed pattern has uniform ink color and rich layers.

[0003] After the rubber roller is used for a period of time, it will wear out, causing the printed pattern to become blurred. Therefore, the rubber roller needs to be replaced. To ensure the printing quality, the printing components on the outside of the rubber roller are replaced. However, the commonly used rubber roller does not have a good stable structure to assist the connection stability between the rubber roller and the printing components, which may cause the printing components and the rubber roller to loosen, affecting the printing quality. SUMMARY

[0004] The present disclosure relates to a wear-resistant rubber roller for a printing machine to solve the problem of loosening between the printing components and the rubber roller, which may affect the printing quality.

[0005] The utility model relates to a wear -resisting rubber roller for printing machine, by the following specific technical means achieves:

[0006] The utility model provides a wear -resisting rubber roller for printing machine, include: connecting shaft, connecting sleeve is installed outside the connecting shaft, the fixed side seat is symmetrically fixed and installed to both ends of connecting shaft, connecting shaft includes: connecting groove, the shape of connecting groove is long strip groove structure, and the number of connecting groove is eight, and connecting groove is arranged in the outside of connecting shaft in ring array, fixed sleeve is equipped with screw thread structure outside fixed sleeve, and the number of fixed sleeve is two, and fixed sleeve is fixed to both ends of connecting shaft in symmetry.

[0007] As a preferred scheme of the utility model, the connecting shaft further includes: a limiting block, a limiting tooth is provided outside the limiting block, and the limiting block is fixed to one side of the fixed sleeve; a transmission shaft is fixed to one side of the limiting block.

[0008] As a preferred scheme of the utility model, the connecting sleeve includes: a connecting block, the shape of the connecting block is long strip block structure, and the number of connecting blocks is eight, and the connecting blocks are integrally arranged on the inner side of the connecting sleeve in ring array; the connecting block is matched with the connecting groove.

[0009] As a preferred embodiment of this utility model, the connecting sleeve further includes: a wear-resistant printed sleeve, which is fixed to the outside of the connecting sleeve.

[0010] As a preferred embodiment of this utility model, the fixed side seat includes: a fixed cylinder, which is cylindrical in shape and fixed in the middle of the fixed side seat; the fixed cylinder and the fixed sleeve are threaded together; a connecting side frame, which is four in number and is integrally arranged in a ring array on one side of the fixed side seat; and a limiting slider, which is rectangular in shape and has limiting teeth at its bottom, allowing the slider to slide on the bottom of the connecting side frame; the limiting teeth of the limiting slider engage with the limiting teeth of the limiting block.

[0011] As a preferred embodiment of this utility model, the fixed side seat further includes: a limiting screw, which rotates at one end of the limiting slider; a threaded connection between the limiting screw and the connecting side frame; and a knob, which is fixed to one end of the limiting screw.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By using the connecting sleeve and connecting shaft, when the rubber roller operates under high load for a long time, and the wear-resistant printing sleeve on the surface of the connecting sleeve wears out due to frequent friction with printing plates, paper and other media, the operator only needs to manually rotate the fixed side seat. The fixed cylinder inside will disengage from the fixed sleeve of the rubber roller main shaft through a threaded connection. Disassembly can be completed without the aid of tools, allowing it to detach from the connecting shaft of the rubber roller main shaft. This avoids the complicated steps of disassembling the entire rubber roller as in traditional rubber rollers, reducing the difficulty of operation and the risk of accidental injury.

[0014] When replacing the new connecting sleeve, simply align the connecting block precisely with the connecting groove of the rubber roller spindle and insert it. Then rotate the fixed side seat to re-thread the fixed cylinder and the fixed sleeve, which can quickly complete the fixing of the connecting sleeve. This design not only improves the installation accuracy and avoids the rubber roller running imbalance or printing quality degradation caused by installation deviation, but also ensures the long-term reliability of the connecting sleeve through the stability of the threaded connection.

[0015] To further prevent the fixed side seat from loosening due to vibration or external force, this system innovatively incorporates a linkage locking mechanism between the limiting screw and the limiting slider. After replacing the connecting sleeve, the operator only needs to rotate the knob to rotate the limiting screw and move the limiting slider until the limiting teeth at its bottom are fully engaged with the limiting teeth on the limiting block of the rubber roller main shaft. This effectively prevents the fixed side seat from loosening due to vibration or external force, ensures the long-term stability of the connecting sleeve, and avoids the risk of decreased printing quality or equipment damage caused by unstable operation of the rubber roller.

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0024] Example: As attached Figure 1 To be continued Figure 5 As shown:

[0025] This utility model provides a wear-resistant rubber roller for a printing press, comprising: a connecting shaft 1, with a connecting sleeve 2 installed on the outside of the connecting shaft 1; fixed side seats 3 are fixedly installed symmetrically at both ends of the connecting shaft 1; the connecting shaft 1 includes: a connecting groove 101, the connecting groove 101 being elongated groove structure, and the number of connecting grooves 101 being set to eight, the connecting grooves 101 being arranged in a ring array on the outside of the connecting shaft 1; a fixed sleeve 102, the fixed sleeve 102 having a threaded structure on its outside, and the number of fixed sleeves 102 being set to two, the fixed sleeves 102 being fixed symmetrically at both ends of the connecting shaft 1; a limiting block 103, the limiting block 103 having limiting teeth on its outside, and the limiting block 103 being fixed to one side of the fixed sleeve 102; and a drive shaft 104, the drive shaft 104 being fixed to one side of the limiting block 103.

[0026] The connecting sleeve 2 includes: a connecting block 201, which is a long strip-shaped block structure, and the number of connecting blocks 201 is set to eight. The connecting blocks 201 are arranged in a ring array and integrally disposed inside the connecting sleeve 2; the connecting blocks 201 match the connecting groove 101; and a wear-resistant printed sleeve 202, which is fixed to the outside of the connecting sleeve 2.

[0027] The fixed side seat 3 includes: a fixed cylinder 301, which is cylindrical in shape and fixed in the middle of the fixed side seat 3; the fixed cylinder 301 is threadedly connected to the fixed sleeve 102; a connecting side frame 302, four of which are arranged in a ring array on one side of the fixed side seat 3; a limiting slider 303, which is rectangular in shape and has limiting teeth at its bottom, and slides on the bottom of the connecting side frame 302; the limiting teeth of the limiting slider 303 engage with the limiting teeth of the limiting block 103; a limiting screw 304, which rotates at one end of the limiting slider 303; the limiting screw 304 is threadedly connected to the connecting side frame 302; and a knob 305, which is fixed to one end of the limiting screw 304.

[0028] The specific usage and function of this embodiment: By installing the rubber roller into the printing machine, the printing machine can drive the connecting shaft 1 to rotate through the drive shaft 104, so that the wear-resistant printing sleeve 202 on the outside can perform printing operations.

[0029] When the wear-resistant printing sleeve 202 of the rubber roller wears out after a period of use, the fixing cylinder 301 inside the fixing side seat 3 will disengage from the fixing sleeve 102 by rotating the fixing side seat 3. At this time, the fixing side seat 3 can be disassembled, and then the connecting sleeve 2 can be pulled to disengage from the connecting shaft 1. The connecting sleeve 2 can then be replaced. When installing the new connecting sleeve 2, the connecting block 201 of the connecting sleeve 2 is aligned with the connecting groove 101 and inserted. Then, by rotating the fixing side seat 3, the fixing cylinder 301 of the fixing side seat 3 and the fixing sleeve 102 will disengage. The threaded connection between 102 allows the fixed side seat 3 to be fixed to one end of the connecting sleeve 2, thus completing the replacement operation of the connecting sleeve 2. After the replacement operation of the connecting sleeve 2 is completed, the limiting screw 304 is rotated by rotating the knob 305. The limiting screw 304 will drive the limiting slider 303 to move. The limiting teeth at the bottom of the limiting slider 303 will engage with the limiting teeth of the limiting block 103, thereby restricting the rotation of the fixed side seat 3 and ensuring that the fixed side seat 3 will not rotate, causing the fixed side seat 3 to loosen the connecting sleeve 2.
