[0019] Please see Figure 1-4 This utility model provides a technical solution: an adjustable printing roller for packaging paper, including a roller body 1, a first limiting sleeve 2, a second limiting sleeve 3, and a rubber sleeve 4. End plates 5 are provided at both ends of the roller body 1. The end plates 5 are fastened to the ends of the roller body 1 by several bolts to achieve connection and disassembly between the end plates 5 and the roller body 1. A convex shaft 11 is provided at the center of the outer end of the end plate 5, which is rotatably connected to the frame of the printing press. Several grooves 6 are formed on the surface of the roller body 1 along its length. The first limiting sleeve 2 and the second limiting sleeve 3 are sleeved on the roller body 1. Several countersunk holes 7 are formed in the first limiting sleeve 2 and the second limiting sleeve 3. Threads are formed on the inner wall of the countersunk holes 7. Locking bolts 8 are provided in the countersunk holes 7 of the first limiting sleeve 2 and the second limiting sleeve 3. The inner end is set in one of the grooves 6 of the roller and pressed into the groove 6. The roller body 1 is also fitted with a rubber sleeve 4. The rubber sleeve 4 is located between the first limiting sleeve 2 and the second limiting sleeve 3. The outer diameters of the first limiting sleeve 2, the second limiting sleeve 3, the rubber sleeve 4 and the end plate 5 are the same to ensure that the first limiting sleeve 2, the second limiting sleeve 3, the rubber sleeve 4 and the end plate 5 will not contact the pigment roller. Only the rubber punch 9 contacts the pigment roller. The lower part of the pigment roller enters the pigment pool. The surface of the rubber sleeve 4 is provided with a rubber punch 9. The inner wall of the rubber sleeve 4 is provided with a number of limiting protrusions 10. The limiting protrusions 10 are slidably set in the corresponding groove 6 of the roller body 1. The width of the limiting protrusions 10 is the same as the width of the groove 6 to ensure that the rubber sleeve 4 will not loosen when the limiting protrusions 10 enter the groove 6.

[0020] Installation method and operating principle: First, place the rubber sleeve 4 onto the roller body 1 and insert the limiting protrusion 10 into the corresponding groove 6. Then, place the first limiting sleeve 2 and the second limiting sleeve 3 onto the roller body 1 respectively, positioned on both sides of the rubber sleeve 4.

Next, install the end plates 5 at both ends of the roller body 1 with bolts. In use, install the printing roller in the frame of the printing equipment through the convex shaft 11. The printing roller is parallel to the pigment roller, and the rubber protrusion 9 is in contact with the pigment roller. When the roller body 1 rotates, it matches the speed of the paper advance, thereby printing the pattern or text on the corresponding position of the packaging paper through the rubber protrusion 9. If the feeding position is slightly off, loosen the locking bolts 8, adjust the positions of the first limiting sleeve 2, the second limiting sleeve 3, and the rubber sleeve 4, and then tighten the locking bolts 8. This utility model has a reasonable structure. The roller body 1 is fitted with a rubber sleeve 4, a first limiting sleeve 2, and a second limiting sleeve 3. Through the cooperation of the first limiting sleeve 2 and the second limiting sleeve 3, the position of the rubber sleeve 4 can be adjusted and limited. When the feeding position is deviated, the position of the rubber sleeve 4 can be adjusted without adjusting the feeding position, which greatly improves the flexibility and convenience. In addition, the rubber sleeve 4 is inserted into the groove 6 of the roller body 1 through the limiting protrusion 10, which ensures that the rubber sleeve 4 will not easily slide when the printing roller rotates, thereby ensuring that the printing will not be deviated.
