Description

Technical Field

[0001] The utility model relates to the technical field of plate rollers, in particular to a printing plate roller which is easy to install. Background Art

[0002] The plate roller, as one of the core components of printing equipment, is cylindrical in shape and is carefully crafted entirely from metal. Its surface is finely engraved and carries a variety of exquisite patterns. During the printing operation, the inking system is responsible for evenly applying the ink to the plate roller. The plate roller then plays its key role in accurately transferring the pattern to the surface of paper, film and other substrates.

[0003] The existing patent (publication number: CN221213026U) discloses that "the utility model relates to the field of plate roller technology, and in particular to a printing plate roller that is easy to install, including a printing plate roller, one end of the printing plate roller is fixedly connected to a plate body, the outer wall of the plate body is gap-matched with the groove at one end of the rotating plate, the groove at one end of the rotating plate is fixedly connected to a rubber pad, the top of the rubber pad is in contact with the bottom of the plate body, the outer wall of the printing plate roller is processed with a print, and a mounting structure is provided above the plate body. Through the coordination of the printing plate roller, print, plate body, rotating plate, vertical plate, motor, rubber pad and mounting structure, when the device is in use, the plate body can be placed in the groove of the rotating plate, and then the inclined block moves the cross bar inward. When the printing plate roller continues to move downward, the spring drives the cross bar to move outward, so that the cross bar is inserted into the groove of the rotating plate, thereby realizing the installation of the printing plate roller, which is convenient for the staff to place the printing plate roller on the rotating plate and directly complete the installation, which is convenient for installation."

[0004] In the process of implementing this application, the inventors discovered that the prior art has the following problems:

In addition, the print on the outside of the printing plate roller is fixed and cannot be quickly disassembled and replaced, which limits the flexibility of the equipment and increases maintenance costs. As a result, when it is necessary to replace the print with a different pattern or specification, the entire plate roller body must be replaced, resulting in high costs.

[0006] Therefore, those skilled in the art provide a printing plate roller that is easy to install to solve the problems raised in the above background technology. Utility Model Content

Then, the printing roller is slid and removed from the outside of the printing roller body. The simple replacement process reduces material loss and labor costs during the operation, and effectively saves the overall replacement cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Reference Figures 1-6 , an embodiment provided by the utility model:

[0031] A printing plate roller that is easy to install, including a plate roller body 1 and a motor 4, a printing roller 5 is clamped on the outside of the plate roller body 1, fixed blocks 8 are fixed on both sides of the plate roller body 1, connecting rings 6 are threadedly connected on both sides of the plate roller body 1, and a rotating shaft 3 is threadedly connected inside the two connecting rings 6 on opposite sides. The output end of the motor 4 is fixed on one side of the two rotating shafts 3, and a mounting mechanism 2 is provided inside the two fixed blocks 8. The mounting mechanism 2 includes a rotating column 203, a first spring 205 is fixedly provided inside the rotating column 203, a handle 204 is slidably provided inside the rotating column 203, and a limited block 206 is fixedly provided on one side of the handle 204. Two clamping blocks 201 are slidably provided inside the two fixed blocks 8, and a second spring 207 is fixed on the opposite side of each of the four clamping blocks 201. The four second springs 207 are fixed on the opposite side of each other. The springs 207 are fixed on opposite sides of each other at the front and rear ends of the two fixed blocks 8, and the four clamping blocks 201 are fixed on opposite sides of each other with a connecting rope 208. The four connecting ropes 208 are wound around the outside of the rotating column 203 on opposite sides of each other, and the lower end of the rotating column 203 is rotatably set on the side of the lower end of one of the two fixed blocks 8 close to the motor 4. A limiting block 206 is fixed on the side of the front end of the handle 204 close to the fixed block 8. A plurality of limiting grooves 202 are provided on the side of the upper end of one of the two fixed blocks 8 close to the motor 4. The outside of the limiting block 206 is slidably set inside one of the plurality of limiting grooves 202. A first spring 205 is fixed on the lower end of the outside of the handle 204, and the upper end of the first spring 205 is fixed on the side of the upper end of one of the two fixed blocks 8 close to the motor 4.

[0032] Specifically, when installing the plate roller body 1, the fixing blocks 8 on both sides of the plate roller body 1 are aligned with the grooves at the upper ends of the two rotating shafts 3, and then the fixing blocks 8 are gradually inserted into the interior of the rotating shaft 3. At this time, the clamping block 201 inside the fixing block 8 will be squeezed by the inner wall of the rotating shaft 3, so that the clamping block 201 gradually moves toward each other and squeezes the second spring 207 connected thereto, so that it shrinks inside the fixing block 8. When the fixing block 8 moves to the final position, the second spring 207 rebounds and pushes the clamping block 201 to reset, so that the clamping block 201 is embedded in the interior of the rotating shaft 3, thereby realizing rapid installation of the plate roller body 1. Then, by rotating the connecting ring 6 outside the rotating shaft 3, the connection between the rotating shaft 3 and the plate roller body 1 is further strengthened to improve the overall connection stability. Subsequently, the motor 4 is started to drive the plate roller body 1 to rotate through the rotating shaft 3 to perform the printing operation.

[0033] When the block 201 gradually shrinks inside the fixed block 8, the rotation of the handle 204 is stopped, and the limiting block 206 is re-embedded in the limiting groove 202, and then the roller body 1 can be taken out from the inside of the rotating shaft 3, which is convenient for operation.

[0034] Reference Figure 1-Figure 7 , a replacement mechanism 7 is provided inside the plate roller body 1, and the replacement mechanism 7 includes two fixed rods 702, and compression springs 705 are fixed on both sides of the inside of the plate roller body 1, and one of the two fixed rods 702 is fixedly provided with an oblique block 706 on the side away from the motor 4, and the oblique block 706 is slidingly provided on the side of one of the two fixed blocks 8 away from the motor 4. One of the two fixed rods 702 is fixedly provided with a trapezoidal block 707 on the side close to the motor 4, and two pressure blocks 701 are slidingly provided on the side close to the motor 4 of the two fixed blocks 8. The two pressure blocks 701 are slidingly provided at the front and rear ends of the trapezoidal block 707 on the opposite side. The opposite sides of the two compression springs 705 are respectively fixed on the opposite sides of the two fixed rods 702, and a plurality of rotating blocks 703 are rotatably provided on the opposite sides of the two fixed rods 702. A fixed plate 704 is rotatably provided between the opposite sides of the multiple rotating blocks 703, and the external surfaces of the multiple fixed plates 704 are respectively slidably provided inside the plate roller body 1, and the printing roller 5 is internally slidably provided on the opposite sides of the multiple fixed plates 704;

[0035] Specifically, when the printing roller 5 outside the plate roller body 1 needs to be replaced, the plate roller body 1 is first taken out from the rotating shaft 3. At this time, the compression spring 705 pushes the fixed rod 702 to move inside the plate roller body 1, and then the trapezoidal block 707 pushes the pressing block 701 to slide oppositely inside the fixed block 8. The movement of the fixed rod 702 will cause the rotating block 703 to rotate, so that the fixed plate 704 moves toward each other inside the plate roller body 1, and then the fixed plate 704 releases the clamping of the printing roller 5 outside the plate roller body 1. Subsequently, the printing roller 5 is disassembled from the outside of the plate roller body 1 by sliding it, and then the required To install the printing roller 5, first slide it into the outside of the printing roller body 1, and then install the printing roller body 1 in the rotating shaft 3. At this time, the pressing block 701 is squeezed and moves toward each other, so that the trapezoidal block 707 drives the fixed rod 702 to move, prompting the rotating block 703 to rotate, so that the fixed plate 704 moves oppositely. At the same time, the oblique block 706 is also squeezed, so that the fixed rod 702 moves and causes the rotating block 703 to rotate. Further, the fixed plate 704 moves toward each other, so that the printing roller 5 is tightly clamped. Replacing the printing roller 5 not only saves costs, but also reduces downtime and improves production efficiency.

[0036] Working principle: When the printing roller 5 outside the printing roller body 1 needs to be replaced, the printing roller body 1 is first removed from the rotating shaft 3. At this time, the built-in compression spring 705 will push the fixed rod 702 to slide inside the printing roller body 1, and the trapezoidal block 707 will push the pressing block 701 to slide toward each other inside the fixed block 8. As the fixed rod 702 moves, the rotating block 703 rotates, causing the fixed plate 704 to move toward each other inside the printing roller body 1, thereby releasing the clamping of the printing roller 5 and simplifying the replacement process of the printing roller 5.

[0037] Secondly, when installing the plate roller body 1, first align the fixing block 8 with the groove at the upper end of the rotating shaft 3 so that the fixing block 8 gradually slides into the interior of the rotating shaft 3. At this time, the card block 201 inside the fixing block 8 will be squeezed by the inner wall of the rotating shaft 3, causing the card block 201 to gradually move inward and compress the second spring 207 connected to it, shrinking inside the fixing block 8. When the fixing block 8 moves to the final position, the compressed second spring 207 rebounds, pushing the card block 201 to reset and embed into the corresponding position inside the rotating shaft 3, thereby realizing a quick and stable installation of the plate roller body 1. In order to further enhance the stability of the connection, the connection between the rotating shaft 3 and the plate roller body 1 is locked by rotating the connecting ring 6 outside the rotating shaft 3, ensuring that during the printing process, even if encountering large mechanical stress or vibration, the plate roller body 1 will not loosen or detach, thereby ensuring the stability and accuracy of the printing operation. Subsequently, the motor 4 is started to drive the plate roller body 1 to operate through the rotating shaft 3 to start the printing operation.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
