Description

Technical Field

[0001] This utility model relates to the field of vacuum roller mesh sleeves, and in particular to a fastening structure for vacuum roller mesh sleeves. Background Technology

[0002] Vacuum roller sleeves are accessories used for vacuum rollers, usually made of materials such as rubber or polyurethane. Their main function is to protect the roller surface, prevent wear and scratches, and at the same time improve the roller's friction and enhance the friction effect between the roller and the material. Vacuum roller sleeves are usually made of materials such as rubber or polyurethane, which have good wear resistance and elasticity.

[0003] The prior art utility model patent with publication number CN 221094669 U proposes a vacuum roller mesh sleeve fastening structure, which uses an adjusting component set on one side of the flange to drive the flanges on both sides of the mesh sleeve to move in opposite directions on the vacuum roller, thereby pulling the mesh sleeve towards both sides of the mesh sleeve, so as to make the mesh sleeve more flatly wrapped on the roller surface. This avoids the problem of the mesh sleeve not being flat enough due to the bulging shape of the mesh sleeve caused by the force of the locking component on the mesh sleeve when the mesh sleeve is held against the flange and limited to the outside of the roller surface.

[0004] However, its adjustment mechanism is relatively complex, and the tensioning and tightening function of the mesh sleeve is achieved by adjusting multiple sets of bolts. In actual operation, it is time-consuming, requiring operation one by one, and it is impossible to ensure that the degree of adjustment of the bolts is consistent, which can easily affect the quality and effect of the mesh sleeve and reduce the practicality of the device. Therefore, we need to upgrade and modify the existing technology to overcome the existing problems and shortcomings. Utility Model Content

[0005] The purpose of this invention is to provide a vacuum roller mesh sleeve fastening structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1As shown in Figure 4, this embodiment provides a vacuum roller mesh sleeve fastening structure, including a device body 1. The device body 1 includes a main roller body 2, side cover plates 5, fixing sleeves 6, fastening components 7, and disassembly / assembly components 8. A main shaft body 3 is inserted into the main roller body 2, and an outer mesh sleeve 4 is fitted onto the outside of the main roller body 2. Insertion grooves 21 and several fixing holes 22 are respectively opened at both ends of the main roller body 2. Two sets of side cover plates 5 are provided and are respectively connected to the outside of the insertion grooves 21 on both sides. A fixing sleeve 6 is fixedly installed on the outer end of the left side cover plate 5. The fastening components 7 are rotatably connected. On the right side cover plate 5, the disassembly and assembly assembly 8 is set on the side cover plate 5 and connected to the main roller body 2. The outer ring of the side cover plate 5 has side through holes 51 arranged in a ring array, and the front of the side cover plate 5 has external through holes 52 arranged in a ring array. The wire harnesses on both sides of the outer mesh sleeve 4 pass through the side through holes 51 and external through holes 52 respectively. The wire harnesses on both sides of the outer mesh sleeve 4 are connected to the fixing sleeve 6 and the connecting block 73 in sequence. The side through holes 51 and external through holes 52 facilitate the connection of both ends of the outer mesh sleeve 4 to the fixing sleeve 6 and the connecting block 73 respectively, which facilitates the stretching and tightening of the outer mesh sleeve 4.

[0026] Preferably, the fastening assembly 7 includes a ratchet disc 71, a rotating shaft 72 is provided on the inner side of the ratchet disc 71 and a connecting block 73 is provided on the outer side of the rotating shaft 72, a connecting shaft 74 is provided on one side of the ratchet disc 71, and a limit block 75 and a counterweight block 76 are respectively provided at both ends of the connecting shaft 74. The rotating shaft 72 and the connecting shaft 74 are rotatably connected to the outer end of the side cover plate 5 on the right side, and the limit block 75 is engaged with one side of the ratchet disc 71.

[0027] The ratchet disc 71 and connecting block 73 are controlled to rotate by rotating shaft 72, which in turn drives the outer mesh sleeve 4 to retract into the right side cover plate 5. The ratchet disc 71 is stopped by limit block 75 to prevent it from reversing. This enables quick retraction and fastening of the outer mesh sleeve 4, preventing it from loosening and moving towards the center during use. The structure is simple and easy to operate, and there is no need to adjust multiple sets of bolts for control, which improves the practicality of the device.

[0028] Preferably, the disassembly and assembly component 8 includes a connection hole 81, a connection bolt 82 is installed in the connection hole 81, and a plug plate 83 is provided on the inner side of the connection hole 81. The connection hole 81 is opened on the side cover plate 5 and corresponds to the fixing hole 22. The inner side of the connection bolt 82 is screwed into the fixing hole 22, and the plug plate 83 is fixed on the inner side of the side cover plate 5 and sealed in the plug groove 21.

[0029] The side cover plate 5 is connected by the plug plate 83 and the plug groove 21, and the connecting hole 81 and the fixing hole 22 are connected and fixed by the connecting bolt 82, so that the side cover plate 5 is fixed on the side of the main roller body 2. This enables quick installation and fixing of the side cover plate 5, facilitates quick disassembly and assembly of the two side fixing sleeves 6 and fastening components 7, and makes it convenient to connect and install with the outer net sleeve 4.

[0030] The working principle and process of this utility model are as follows: First, the outer mesh sleeve 4 can be installed on the outer surface of the main roller body 2. The side cover plate 5 is connected to the insertion slots 21 on both sides of the main roller body 2 through the insertion plate 83. The wire ends extending from both ends of the outer mesh sleeve 4 are passed through the side through hole 51 and the outer through hole 52 respectively. Then, the wire ends on both sides of the outer mesh sleeve 4 are connected to the interface of the fixing sleeve 6 and the connecting block 73. At this time, the side cover plate 5 can be fixed by the connecting bolt 82 and the fixing hole 22. When it is necessary to adjust the tightness of the outer mesh sleeve 4, the connecting shaft 74 can be rotated by the counterweight 76. The connecting shaft 74 drives the limiting block 75 to rotate and disengage from the ratchet disk 71. Rotating the ratchet disk 71 causes the outer mesh sleeve 4 to retract into the side cover plate 5 through the connecting block 73, so that the outer mesh sleeve 4 can be tightened. Then, the ratchet disk 71 is released and the limiting block 75 is used to reposition it. The operation is simple and convenient.
