Description

Technical Field

[0001] This utility model relates to the field of melamine paper production, and in particular to a quick-change roller structure for melamine paper production. Background Technology

[0002] Melamine paper is a decorative paper made primarily of melamine resin. It is mainly used to manufacture high-pressure impregnated paper (HPL) or decorative coated paper. A rubber roller, also known as a rubber roller, is a roller with a surface covered with rubber or other elastic materials. It is widely used in printing, papermaking, rubber processing, leather, plastics, and textile industries, primarily for processes such as conveying, compaction, printing, and gluing. After a period of use, if the rubber roller becomes damaged, it is necessary to replace the roller itself or its external rubber sleeve.

[0003] The existing traditional rubber roller installation structure is cumbersome and inconvenient to disassemble and assemble, making it very inconvenient to replace the rubber roller. As a result, the replacement time is long and the efficiency is low. At the same time, the existing traditional rubber roller connection structure cannot realize the operation of replacing the rubber sleeve separately. If the rubber sleeve needs to be replaced, the entire roller body must be removed and replaced, which is not practical. To solve the above problems, a quick rubber roller replacement structure for melamine paper production is proposed. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1-2 This utility model provides an embodiment of a quick-change roller structure for melamine paper production, comprising a roller body 1, which is a rubber roller for melamine paper production. A roller changing mechanism 2 is provided on both the left and right sides of the roller body 1, which is used to replace the roller body 1 or the rubber sleeve 13. A connecting shaft 3 is provided on the side of each roller changing mechanism 2 that is far apart from each other, which is used to install the overall structure on the melamine paper production equipment. The roller body 1 includes a roller shaft 11, which is used to connect various components. A mounting base 24 is fixedly connected to the roller shaft 11. A roller 12 is fixedly connected to the outside of the roller shaft 11. A rubber sleeve 13, which can be made of rubber or other materials, is sleeved on the outside of the roller 12.

[0031] like Figures 3-4As shown, the rubber roller changing mechanism 2 includes a main rod 21, which is used to connect various components. A control sleeve 26 is threadedly connected to the outer wall of the main rod 21, which is used to control the disassembly and assembly of the mounting block 22 and the fixing block 23, as well as the use of the connecting block 25. The inner wall of the control sleeve 26 is provided with threads from left to right that are adapted to the main rod 21. The mounting block 22 is fixedly connected to the side of the main rod 21 away from the roller body 1. A limit block 221 is fixedly connected to the lower part of the mounting block 22, which is used to limit the movement between the mounting block 22 and the fixing block 23. A fixing block 23 is provided at the lower part of the mounting block 22. A limit groove 231 is opened in the middle of the fixing block 23, which is adapted to the limit block 221. The limit block 221 and the limit groove 231 are movably connected. The side of the control sleeve 26 away from the roller body 1 is sleeved on the outside of the mounting block 22 and the fixing block 23, which is used to limit the movement between the mounting block 22 and the fixing block 23. The fixing block 23 is fixedly connected to the connecting shaft 3.

[0032] Furthermore, the mounting block 22 and the fixing block 23 can together form a cylinder with the same diameter as the main rod 21 and the connecting shaft 3. A mounting base 24 is fixedly connected to the side of the main rod 21 near the roller body 1, which is used to connect with the connecting block 25. The connecting block 25 is rotatably connected to the middle of the mounting base 24. The connecting block 25 is fixed to the roller shaft 11. The control sleeve 26 is sleeved on the outside of the mounting base 24 near the roller body 1. It is used to limit the position of the connecting block 25 to prevent it from shaking when the roller body 1 is in use. The width of the connecting block 25 is the same as the width of the mounting base 24 and the main rod 21. Sufficient space is left between the mounting base 24 and the roller body 1 and between the connecting shaft 3 and the melamine paper production equipment for the control sleeve 26 to adjust.

[0033] Working principle: If it is necessary to replace the entire roller body 1, rotate the control sleeve 26 so that it moves along the main rod 21 toward the roller 12. This allows the side of the control sleeve 26 closest to the roller 12 to be fitted over the outside of the roller shaft 11, mounting base 24, and connecting block 25, thus fully exposing the mounting block 22 and fixing block 23. Once both control sleeves 26 are adjusted to this position, the roller 12 can be pulled. This causes the roller 12 to move the main rod 21 and the mounting block 22 connected to the main rod 21 away from the fixing block 23 via the roller shaft 11. This disengages the limiting block 221 from the limiting groove 231, thus completing the disassembly of the roller body 1.

[0034] If only the rubber sleeve 13 on the outside of the roller body 1 needs to be replaced, adjust the control sleeve 26 on one side of the roller body 1 as described above, and rotate the control sleeve 26 on the other side in the opposite direction to move it towards the connecting shaft 3. This moves the control sleeve 26 away from the roller body 1 and onto the outside of the connecting shaft 3, mounting block 22, and fixing block 23, exposing the mounting base 24 and connecting block 25. Then, pull the roller body 1 to disengage the mounting block 22 and fixing block 23 exposed at one end of the roller body 1. At this point, the other end of the roller body 1... The connecting block 25 will rotate inside the mounting base 24. Then, the rubber sleeve 13 will be removed from the outside of the roller 12, and a new rubber sleeve 13 will be put on the outside of the roller 12. Then, the limiting block 221 of the lower part of the mounting block 22 exposed on one side of the roller body 1 will be inserted into the limiting groove 231 opened on the upper part of the fixing block 23. Then, the control sleeve 26 will be rotated so that the control sleeve 26 is put on the outside of the fixing block 23 and the mounting block 22. At the same time, the control sleeve 26 on the other side will be adjusted so that the control sleeve 26 is put on the outside of the mounting base 24 and the connecting block 25.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
