Description

Technical Field

[0001] The utility model relates to the technical field of hardware tools, in particular to a quick disassembly and assembly tool for replacing the screen mesh of a tobacco high-frequency vibrating screen. Background Art

[0002] During the production process of cigarette sticks, there are often cigarette sticks with unqualified sizes after shearing. At this time, these unqualified cigarette sticks need to be transferred to the waste cigarette recycling area, and the shredded tobacco in the unqualified cigarette sticks is recycled through the high-frequency vibration of the vibrating screen in the waste cigarette recycling area. However, since different specifications and brands of cigarette sticks need to be matched with corresponding-sized round-hole screen meshes when recycling shredded tobacco, it results in the frequent replacement of the round-hole screen mesh on the vibrating screen in the waste cigarette recycling area. And the round-hole screen mesh is installed on the vibrating screen by tightening with multiple tightening bolts. Frequent replacement of the round-hole screen mesh means that maintenance personnel need to frequently perform the replacement operation of the round-hole screen mesh.

[0003] Currently, when replacing the round-hole screen mesh, a manual wrench is directly used to hold the end of the tightening bolt to disassemble and assemble the tightening bolt. However, due to the special installation position of the tightening bolt on the vibrating screen, the movement space of the manual wrench is limited, which not only increases the labor intensity of the maintenance personnel but also results in a low replacement efficiency of the round-hole screen mesh. At the same time, due to the limited installation and disassembly operation space of the tightening bolt, the tightening bolt is often obliquely placed into the threaded hole for tightening installation, resulting in damage to the thread on the tightening bolt. Content of the Utility Model

[0004] In order to solve the above technical problems, the utility model provides a quick disassembly and assembly tool for replacing the screen mesh of a tobacco high-frequency vibrating screen, which can improve the replacement efficiency of the round-hole screen mesh, reduce the labor intensity of maintenance personnel, and reduce the risk of damage to the thread of the tightening bolt.

[0005] The utility model adopts the following technical solutions:

[0006] The utility model provides a quick disassembly and assembly tool for replacing the screen mesh of a tobacco high-frequency vibrating screen, which is used for disassembling and assembling the tightening bolts that fasten the round-hole screen mesh on the vibrating screen in the waste cigarette recycling area. It includes a central shaft, a sleeve, and a socket end. The central shaft is rotatably inserted into the sleeve around its axis, and both axial ends of the central shaft extend out of the sleeve. The socket end is arranged at one axial end of the central shaft and can be socketed and matched with the end of the tightening bolt. A clamping groove is formed by concave inward at the other axial end of the central shaft, and the clamping groove can be clamped and matched with the connecting head of a ratchet wrench.

[0007] Preferably, the inner diameter of the inner hole of the sleeve is larger than the shaft diameter of the central shaft. A bearing is installed at each axial end of the inner hole of the sleeve, and both bearings are installed in cooperation with the central shaft through their inner rings.

[0008] Preferably, the socket end includes a socket joint and a chassis. A socket groove capable of socket-fitting with the end of the tightening bolt is formed on the socket joint. The socket joint is fixed on the chassis, and the chassis is fixedly connected to one axial end of the central shaft.

[0009] Preferably, the socket groove on the socket joint is a plum blossom-shaped notch.

[0010] Preferably, the clamping groove is a square notch.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] When the quick disassembly and assembly tool for replacing the screen of the tobacco high-frequency vibrating sieve of the present utility model is in use, it can be socket-fitted with the tightening bolt for fastening the round-hole screen on the vibrating sieve in the waste cigarette recycling area through the socket end at one end of the central shaft. Then, the connecting head of the ratchet wrench is socket-fitted with the clamping groove at the other end of the central shaft. By holding the sleeve and turning the ratchet wrench, the disassembly and assembly of the tightening bolt can be realized, thereby realizing the disassembly and assembly of the round-hole screen and the vibrating sieve in the waste cigarette recycling area.

[0013] At the same time, since the quick disassembly and assembly tool for replacing the screen of the tobacco high-frequency vibrating sieve of the present utility model transfers the force application position of the wrench from the original narrow space to the outside after being socket-fitted with the tightening bolt, the construction personnel can use a more labor-saving ratchet wrench to disassemble and assemble the tightening bolt, and can also adjust the screwing angle of the tightening bolt by manually holding the sleeve, avoiding the problem of skew installation of the tightening bolt.
