Description

Technical Field

[0001] This utility model belongs to the field of embossing roller technology, and in particular relates to an embossing roller with quick roller sleeve replacement. Background Technology

[0002] An embossing roller is an industrial roller used to press specific patterns or designs onto the surface of a material. It is usually made of metal and has various patterns engraved on its surface. By contacting the material and applying pressure, it achieves the embossing process and is widely used in industries such as papermaking, leather, and plastics.

[0003] Most embossing roller sleeves have some drawbacks during use. For example, over long-term use, the sleeves may become worn, corroded, deformed, or have their surface patterns damaged, affecting the embossing effect and product quality. In such cases, timely replacement of the sleeves is necessary to ensure the normal operation of the embossing roller and the production of qualified products. The sleeves are typically fixed with bolts, but these bolts may strip over time, making disassembly difficult, complex, and time-consuming. Therefore, we propose an embossing roller with a quick-change sleeve. Utility Model Content

[0004] The purpose of this invention is to provide an embossing roller with quick-change roller sleeves to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides an embossing roller with quick-change roller sleeve, including a rotating shaft, a first roller sleeve, and a second roller sleeve, and further comprising:

[0006] A plurality of fixing strips are respectively inserted into the first roller sleeve and the second roller sleeve, and the plurality of fixing strips are all fixedly connected to the rotating shaft. The first roller sleeve and the second roller sleeve are in close contact, and the first roller sleeve and the second roller sleeve are respectively located on both sides of the rotating shaft.

[0007] The power chamber is located inside the second roller sleeve. Two sliding strips are slidably installed inside the power chamber. Several limiting strips are provided inside the power chamber and within the two sliding strips. Several guide grooves are provided in both sliding strips. Guide posts are slidably installed in the several guide grooves. The several guide posts are fixedly connected to the several limiting strips. One end of each of the several limiting strips passes through the power chamber and extends into the first roller sleeve. One end of each of the several limiting strips is inserted into the first roller sleeve.

[0008] A drive assembly, located inside the second roller sleeve, is used to drive the two sliding bars to slide.

[0009] In this technical solution, when it is necessary to disassemble the first roller sleeve and the second roller sleeve, the driving component can drive the two sliding bars to slide upward. The two sliding bars drive the several guide posts to slide away from the first roller sleeve through several guide grooves. Then, the several guide posts drive the several limiting strips to slide into the power cavity. When the several limiting strips are all disengaged from the first roller sleeve, the first roller sleeve and the second roller sleeve can be taken out, which facilitates the disassembly of the first roller sleeve and the second roller sleeve. The first roller sleeve and the second roller sleeve can be installed through the above reverse operation. The operation is simple and convenient and does not require the use of tools.

[0010] In the above technical solution, the driving component further includes:

[0011] An arc-shaped plate is slidably installed inside a power cavity. Several springs fixed to the inner wall of the power cavity are fixedly installed at the bottom of the arc-shaped plate. First racks are fixedly installed on both sides of the arc-shaped plate. Gears are meshed on one side of each of the two first racks. Second racks are meshed on one side of each of the two gears. The two second racks are fixedly connected to two sliding bars respectively.

[0012] In this technical solution, the arc-shaped plate slides downwards, while several springs are compressed and contracted. The arc-shaped plate drives two first racks to slide downwards, and the two first racks drive two gears to rotate in the forward direction. The two gears drive two second racks meshing with them to slide upwards, and the two second racks drive two sliding strips to slide upwards. The two sliding strips drive several guide posts to slide away from the first roller sleeve through several guide grooves. Subsequently, the several guide posts drive several limiting strips to slide into the power cavity. When all the limiting strips disengage from the first roller sleeve, the first roller sleeve and the second roller sleeve can be removed, facilitating the disassembly of the first roller sleeve and the second roller sleeve. The first roller sleeve and the second roller sleeve can be installed through the above reverse operation, and the operation is simple and convenient, requiring no tools.

[0013] In the above technical solution, the driving component further includes:

[0014] A fixed column is fixedly installed on an arc-shaped plate. A sliding groove is provided inside the fixed column, and a sliding column is slidably installed in the sliding groove. Several tension springs that are fixed to the inner wall of the sliding groove are fixedly installed at one end of the sliding column, and a fixed plate is fixedly installed at the other end of the sliding column through the sliding groove.

[0015] In this technical solution, when it is necessary to disassemble the first roller sleeve and the second roller sleeve, firstly, the fixing plate is slid towards the rotating shaft. The fixing plate drives the sliding column to slide, and at the same time, several tension springs are stretched. After the fixing plate is separated from the power cavity, the fixing plate slides downward and drives the fixing column to slide downward. The fixing column drives the arc plate to slide downward, and at the same time, several springs are compressed and contracted. Then, the fixing plate is released. Under the action of the tension of several tension springs, the sliding column and the fixing plate slide towards the direction of the tension springs, which can fix the position of the fixing plate.

[0016] In the above technical solution, furthermore, several of the limiting strips, two first racks, two second racks, fixing posts and fixing plates are all slidably connected to the power cavity, and the two gears are all rotatably connected to the power cavity.

[0017] In this technical solution, it is ensured that several limiting strips, two first racks, two second racks, a fixed column, and a fixed plate can all slide within the power cavity, thus ensuring that both gears can rotate within the power cavity.

[0018] In the above technical solution, further, several of the limiting strips are distributed at equal intervals on the second roller sleeve.

[0019] In this technical solution, the first roller sleeve and the second roller sleeve are securely fixed.

[0020] In the above technical solution, furthermore, the diameter of the guide post is the same as the size of the guide groove.

[0021] In this technical solution, the stability of the guide post sliding within the guide groove is ensured.

[0022] In the above technical solution, the rotating shaft and several fixing strips are integrally formed.

[0023] In this technical solution, the stability of the rotating shaft and several fixing bars is ensured during use.

[0024] The beneficial effects of this utility model are:

[0025] This quick-change embossing roller allows for easy disassembly of the first and second roller sleeves. A drive assembly drives two sliding bars upwards, which in turn guide guides several guide posts away from the first roller sleeve via guide grooves. These guide posts then guide several limiting strips into the power chamber. Once the limiting strips have disengaged from the first roller sleeve, both the first and second roller sleeves can be removed for easy disassembly. The reverse operation allows for installation of the first and second roller sleeves, making the process simple and convenient without the need for tools. Attached Figure Description
