It includes a roller body for PVC film printing, with a wear-resistant component fitted onto the outer wall of the roller body. The wear-resistant component includes two symmetrically distributed semi-roller sleeves, one above and one below the roller body, respectively. Each semi-roller sleeve has a heat dissipation cavity inside. This invention protects the roller body from wear by using two semi-roller sleeves made of ceramic. Ceramic has excellent wear resistance and thermal conductivity, thus providing wear protection for the roller body, extending its service life during PVC film printing, and reducing the cost of PVC film printing. Simultaneously, three micro-fans at both ends of the semi-roller sleeves facilitate airflow within the heat dissipation cavity, thereby improving the heat dissipation speed of the semi-roller sleeves and preventing high temperatures from reducing their wear resistance.

[0004] The existing technology has the following shortcomings: When the surface of the existing printing roller is damaged during use, the entire roller usually needs to be disassembled and replaced. It is not possible to replace the damaged parts individually, which makes it impossible to quickly put the roller into subsequent work and also increases the cost of PVC film printing.

Figure 1-3 and Figure 5As shown, the printing roller mechanism 2 includes a fixed sleeve 201, which is movably sleeved on the outside of the fixed mechanism 1. A movable sleeve 202 is rotatably installed on one side of the top of the fixed sleeve 201. The limiting mechanism 3 includes a limiting plate 301, with two limiting plates 301 respectively movably sleeved on the outer walls of both ends of the fixed mechanism 1. A fastening pin 303 is provided between the limiting plate 301 and the fixed mechanism 1.

This allows the staff to easily install and disassemble the printing roller mechanism 2 and easily replace damaged parts.

[0023] To facilitate the installation and removal of the limiting plate 301, such as Figure 1-5 As shown, the fixing mechanism 1 includes a fixing shaft 101, a limiting sleeve 102 fixedly sleeved on the outside of the fixing shaft 101, and mounting holes 103 opened on the outer walls of both ends of the fixing shaft 101. A limiting plate 301 is movably sleeved on the end of the fixing shaft 101 near the limiting sleeve 102. A limiting hole 302 is opened on the inner wall of one side of the limiting plate 301. The inner wall of the limiting hole 302 is threadedly connected to the outer wall of the fastening pin 303. The side of the fastening pin 303 away from the limiting hole 302 is threadedly connected to the inner wall of the adjacent mounting hole 103. The fastening pin 303 is threadedly inserted into the limiting hole 302 and threadedly connected to the inner wall of the adjacent mounting hole 103, so that the two limiting plates 301 can be stably installed on both ends of the fixing shaft 101, and at the same time, it allows the staff to easily disassemble the limiting plates 301.

[0024] To securely fix the fixed sleeve 201 and the movable sleeve 202, such as Figure 2-5 As shown, the fixed sleeve 201 and the movable sleeve 202 are respectively movably sleeved on the bottom and top of the limiting sleeve 102. Both ends of the fixed sleeve 201 and the movable sleeve 202 are provided with multiple fixing holes 204. The inner wall of the limiting plate 301 is provided with multiple connecting holes 304 at equal intervals. The inner wall of the connecting hole 304 is threaded to the outer wall of the adjacent fastening bolt 305. The end of the fastening bolt 305 away from the connecting hole 304 is threaded to the inner wall of the adjacent fixing hole 204. The limiting sleeve 102 can install and limit the fixed sleeve 201 and the movable sleeve 202, which can prevent the fixed sleeve 201 and the movable sleeve 202 from moving axially. At the same time, the fastening bolt 305 is threaded into the connecting hole 304 and threaded to the inner wall of the adjacent fixing hole 204, so that the limiting plate 301 can fix the fixed sleeve 201 and the movable sleeve 202.

[0025] To ensure that the fixed sleeve 201 and the movable sleeve 202 remain stable outside the fixed shaft 101, such as Figure 2 and Figure 4-5 As shown, both ends of the bottom of the movable sleeve 202, away from the fixed sleeve 201, are threaded with connecting bolts 203. The ends of the two connecting bolts 203 away from the movable sleeve 202 are threaded to the inner walls of both ends of the fixed sleeve 201.

Then, use fastening pins 303 threaded into the inner wall of the limiting holes 302 and threadedly connected to the inner wall of the adjacent mounting holes 103, so that the two limiting plates 301 can stably fix the outer side of the fixed shaft 101. Then, fit the fixed sleeve 201 onto the outer side of the limiting sleeve 102, so that its two ends are respectively located on the outer side of the bottom of the two limiting plates 301. Then, rotate the movable sleeve 202 from a vertical position to a horizontal position, so that it can fit onto the outer side of the limiting sleeve 102, and at the same time, so that its two ends are located on the outer side of the top of the two limiting plates 301. Finally, use connecting bolts 203 threaded into the movable sleeve 201. The inner walls of both ends are threadedly connected to the inner wall of the fixed sleeve 201, so that the fixed sleeve 201 and the movable sleeve 202 are tightly connected. Then, by adjusting the fixed sleeve 201 and the movable sleeve 202, the multiple connecting holes 304 at the same end can be aligned with the fixed holes 204 at the same end. Then, the fastening bolts 305 are threaded into the inner wall of the connecting holes 304 and threadedly connected to the inner wall of the adjacent fixed holes 204. Thus, the limiting plate 301 can install and fix the fixed sleeve 201 and the movable sleeve 202, so that the staff can easily assemble and disassemble the printing plate roller, and at the same time, the staff can easily replace the damaged parts. This embodiment specifically solves the problem that the existing technology cannot easily replace the damaged parts of the printing plate roller.
