Description

Technical Field

[0001] This utility model relates to the field of printing rubber roller technology, specifically a printing wear-resistant rubber roller. Background Technology

[0002] In the printing industry, wear-resistant rubber rollers are key components for ensuring printing quality. They achieve ink transfer and printing operations through the contact between the surface rubber layer and paper and ink. Currently, most wear-resistant printing rubber rollers on the market consist of a core shaft, a mounting roller, and an outer rubber roller. The core requirement is to ensure a stable connection between the rubber roller and the mounting roller, while also taking into account ease of disassembly and assembly and wear resistance, so as to adapt to the long-term, high-frequency printing operation environment.

[0003] However, the core, mounting roller and outer roller of existing rubber rollers are often fixedly connected as a whole structure. While the core and other metal parts are wear-resistant and not easily damaged, the outer roller, as the part that directly contacts the printing material, wears out quickly. When the outer roller wears to a certain extent and needs to be replaced, the entire roller must be replaced. This results in the replacement of metal materials such as the core that are still in normal use, causing serious waste of metal materials and significantly increasing the cost of use. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a wear-resistant printing roller to solve the problems mentioned in the background section. This invention features a novel structure. By setting a separable roller and mounting roller structure, along with a locking mechanism and a drive mechanism, when the roller wears out, there is no need to replace the mounting roller and mandrel or other metal parts. Simply use the drive mechanism to release the locking mechanism from the roller, remove the old roller, and replace it with a new one. This design allows for the reuse of metal parts that are not easily worn, such as the mandrel and mounting roller, reducing waste of metal materials and lowering operating costs.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a printing wear-resistant rubber roller, including an installation roller, a rubber roller sleeved on the outer side of the installation roller, a mandrel disposed inside the installation roller, multiple annular grooves opened inside the installation roller, a snap-fit ​​mechanism disposed inside each of the multiple annular grooves, an installation groove opened on one side of the installation roller, a spring-loaded spring mounted on one side of the inner wall of the installation groove, one end of the spring-loaded spring being fixedly connected to one side of the mandrel, and a drive mechanism disposed inside the installation groove.

[0006] Furthermore, the snap-fit ​​mechanism includes a mounting bracket fixedly connected to the inner wall of the annular groove. A turntable is rotatably fitted on one side of the mounting bracket, and multiple arc-shaped connecting rods are rotatably fitted on the outer side of the turntable. Multiple T-shaped grooves are opened on the outer side of the mounting bracket, and T-shaped sliders are slidably fitted on the inner walls of the multiple T-shaped grooves. Snap-fit ​​blocks are fixedly connected to the opposite sides of the multiple T-shaped sliders.

[0007] Furthermore, multiple arc-shaped connecting rods are circumferentially arranged on the outer side of the turntable, one end of each arc-shaped connecting rod is rotatably engaged with a T-shaped slider, the locking block is slidably engaged on the inner wall of the annular groove, and the locking block is inserted into the corresponding groove on the inner wall of the rubber roller.

[0008] Furthermore, the driving mechanism includes a driving rod rotatably engaged with one side of the mounting roller, one end of the driving rod extending to the inner wall of the mounting groove and fixedly connected to a driving gear, a driven gear meshing with the driving gear mounted on the spindle, a ratchet fixedly connected to the driving rod, a support block fixedly connected to one side of the mounting roller, and a pawl elastically engaged on one side of the support block.

[0009] Furthermore, the pawl engages with the ratchet, and the pawl rotates on one side of the mounting roller.

[0010] Furthermore, the inner wall of the rubber roller is provided with multiple dovetail grooves, and multiple dovetail blocks that slide in cooperation with the dovetail grooves are fixedly connected to the outer side of the mounting roller.

[0011] Furthermore, a plurality of heat dissipation holes are provided on one side of the rubber roller, and the plurality of heat dissipation holes are arranged circumferentially on one side of the rubber roller.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model, by setting a separable rubber roller and mounting roller structure, as well as a snap-fit ​​mechanism and a drive mechanism, eliminates the need to replace metal parts such as the mounting roller and mandrel after the rubber roller wears out. Instead, the old rubber roller can be removed and replaced with a new one simply by using the drive mechanism to release the snap-fit ​​mechanism from the rubber roller. This design allows metal parts such as the mandrel and mounting roller, which are not easily worn, to be reused, reducing the waste of metal materials and lowering the cost of use.

[0014] 2. By setting up a dovetail block and a dovetail groove matching structure, when the rubber roller is sleeved on the mounting roller, the dovetail block slides into the dovetail groove, which can initially position the two and restrict relative movement. With the subsequent locking mechanism, it can effectively prevent loosening due to vibration during the printing process and ensure printing accuracy. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please refer to Figures 1 to 6 This utility model provides a technical solution: a printing wear-resistant rubber roller, including an installation roller 1, a rubber roller 2 sleeved on the outer side of the installation roller 1, a mandrel 3 inside the installation roller 1, multiple annular grooves 4 inside the installation roller 1, each annular groove 4 having a locking mechanism 5 inside, an installation groove 6 on one side of the installation roller 1, a spring 7 mounted on one side of the inner wall of the installation groove 6, one end of the spring 7 being fixedly connected to one side of the mandrel 3, and a driving mechanism 8 inside the installation groove 6. Multiple dovetail grooves 9 are formed on the inner wall of the rubber roller 2, and multiple dovetail blocks 10 that slide in cooperation with the dovetail grooves 9 are fixedly connected to the outer side of the installation roller 1. Multiple heat dissipation holes 11 are formed on one side of the rubber roller 2, and the multiple heat dissipation holes 11 are circumferentially arranged on one side of the rubber roller 2. When the rubber roller 2 is sleeved on the outside of the mounting roller 1, the dovetail block 10 on the outside of the mounting roller 1 slides into the dovetail groove 9 on the inner wall of the rubber roller 2 to achieve initial positioning. During the printing process, the heat generated by the rubber roller 2 is dissipated through the heat dissipation hole 11 on one side. The cooperation between the dovetail block 10 and the dovetail groove 9 can limit the relative movement of the rubber roller 2 and the mounting roller 1, ensuring that the two are initially aligned, providing a basis for subsequent fixation. The heat dissipation hole 11 can dissipate heat in time, preventing the rubber roller 2 from aging due to high temperature and extending its service life.

[0024] In this embodiment, the snap-fit ​​mechanism 5 includes a mounting bracket 51 fixedly connected to the inner wall of the annular groove 4. A turntable 52 is rotatably fitted on one side of the mounting bracket 51, and multiple arc-shaped connecting rods 53 are rotatably fitted on the outer side of the turntable 52. Multiple T-shaped grooves 54 are formed on the outer side of the mounting bracket 51, and T-shaped sliders 55 are slidably fitted on the inner walls of the multiple T-shaped grooves 54. Snap-fit ​​blocks 56 are fixedly connected to the opposite sides of the multiple T-shaped sliders 55. The multiple arc-shaped connecting rods 53 are circumferentially arranged on the outer side of the turntable 52, and one end of each arc-shaped connecting rod 53 is rotatably fitted with the T-shaped slider 55. The snap-fit ​​blocks 56 are slidably fitted on the inner wall of the annular groove 4 and are inserted into corresponding grooves on the inner wall of the rubber roller 2. When the turntable 52 rotates on the mounting bracket 51, the arc-shaped connecting rod 53 on its outer side moves accordingly, causing the T-shaped slider 55 to slide in the T-shaped groove 54, thereby causing the locking block 56 to extend or retract along the inner wall of the annular groove 4. Through the linkage of components such as the turntable 52 and the arc-shaped connecting rod 53, the locking block 56 can be extended and retracted synchronously. When the locking block 56 extends, it engages with the groove on the inner wall of the rubber roller 2, which can lock the rubber roller 2 and ensure a stable connection between the rubber roller 2 and the mounting roller 1. When it retracts, it can be released from the fixation, which is convenient for the disassembly and replacement of the rubber roller 2. The structure has strong linkage and stable operation.

[0025] In this embodiment, the drive mechanism 8 includes a drive rod 81 rotatably engaged with one side of the mounting roller 1. One end of the drive rod 81 extends to the inner wall of the mounting groove 6 and is fixedly connected to a drive gear 82. A driven gear 83 meshing with the drive gear 82 is mounted on the spindle 3. A ratchet 84 is fixedly connected to the drive rod 81. A support block 85 is fixedly connected to one side of the mounting roller 1, and a pawl 86 is elastically engaged with one side of the support block 85. The pawl 86 engages with the ratchet 84 and is rotatably engaged with one side of the mounting roller 1. Rotating the drive rod 81 causes the drive gear 82 to rotate, which in turn drives the spindle 3 to rotate through meshing with the driven gear 83. At the same time, the ratchet 84 rotates with the drive rod 81, and the pawl 86 engages with the ratchet 84 under the elastic action of the support block 85, restricting the drive rod 81 from rotating in the opposite direction. The drive mechanism 8 provides power for the rotation of the spindle 3, thereby driving the operation of related components. The engagement of the ratchet 84 and the pawl 86 can lock the position of the drive rod 81, preventing it from rotating in the opposite direction and causing the spindle 3 to reset, thus ensuring the stability of actions such as locking.

[0026] When using the device, when installing the rubber roller 2, first place the rubber roller 2 on the outside of the installation roller 1, and use the cooperation between the dovetail block 10 and the dovetail groove 9 to complete the initial positioning. Then, rotate the drive rod 81, and the drive gear 82 drives the driven gear 83 to rotate, causing the spindle 3 to rotate. At this time, the spring 7 is stretched and deformed and stores potential energy. The rotation of the spindle 3 drives the turntable 52 of the snap-fit ​​mechanism 5 to rotate, and pushes the T-shaped slider 55 to move through the arc-shaped connecting rod 53, so that the snap-fit ​​block 56 extends out of the annular groove 4 and snaps the rubber roller 2. At the same time, the ratchet... The ratchet 84 and pawl 86 engage to lock the drive rod 81, ensuring the rubber roller 2 is securely installed. When replacing the rubber roller 2, the ratchet 86 is released from its lock on the ratchet 84, and the spring 7 releases its potential energy to drive the spindle 3 to rotate in the opposite direction, causing the turntable 52 to move in the opposite direction. The arc-shaped connecting rod 53 pulls the T-shaped slider 55 to reset, and the locking block 56 retracts into the annular groove 4, releasing the fixation on the rubber roller 2. The old rubber roller 2 can then be removed and replaced with a new one. Throughout the process, the heat dissipation hole 11 continuously dissipates heat from the rubber roller 2, ensuring its stable working condition.

It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
