AI Technical Summary
In existing technologies, the oil seal of the spider hand of a cigarette machine is difficult to disassemble, requiring the entire spider hand body to be disassembled, which is cumbersome and poses a risk of damaging the equipment.
An oil seal disassembly device was designed, comprising a cylindrical body, a gripper, and a driving component. The gripper uses its barbed structure to hook onto the inner ring of the oil seal, and combined with the axial movement of the driving component, it achieves stable and uniform disassembly of the oil seal.
This method enables quick and safe removal of the oil seal without disassembling the spider phone body, avoiding oil seal deformation and equipment damage caused by traditional methods, thus improving maintenance efficiency and safety.

Abstract
Claims
1. An oil seal dismounting device for a cigarette machine spider hand, characterized in that, include: A cylindrical body (1) with openings at both ends has an inner diameter slightly larger than the outer diameter of the conveyor arm shaft (2) and is used to be fitted onto the outside of the conveyor arm shaft (2). Multiple grippers (3) are formed by extending axially from one end of a cylindrical body (1) and separated from each other by gaps, forming a structure arranged at intervals along the circumference of the cylindrical body (1); each gripper (3) has a wedge-shaped outer contour that gradually thins from the wall thickness of the cylindrical body (1) in the axial direction, and its inner edge is flush with the inner diameter of the cylindrical body (1) so as to be inserted between the conveyor arm shaft (2) and the oil seal (4); the front end of each gripper (3) is provided with an outwardly inclined barb structure, which is suitable for hooking against the inner ring surface of the oil seal (4) so as to achieve stable disassembly during traction. The driving component (5) has one free end and the other end detachably connected to the other end of the cylindrical body (1) opposite to the gripper (3), and the driving component (5) can move axially relative to the cylindrical body (1); The top block (6) is detachably connected to one end of the drive unit (5) located inside the cylindrical body (1).
2. The oil seal dismounting device according to claim 1, characterized in that The driving component (5) is a screw structure with external threads, and its free end is provided with a handle (7); the inner wall of the cylindrical body (1) is provided with an internal thread hole that matches the external thread of the driving component (5). The driving component (5) rotates the handle (7) to make its external thread move relative to the internal thread hole of the cylindrical body (1), thereby realizing the relative displacement between the driving component (5) and the cylindrical body (1).
3. The oil seal removal device of claim 1, wherein The top block (6) is a cylindrical component with an internal threaded hole in the middle for threaded connection with the drive component (5) with external thread. Its outer diameter matches the inner diameter of the cylindrical body (1), and it is installed on the inner side of the cylindrical body (1) and can move along the axial direction of the cylindrical body (1) under the drive of the drive component (5).
4. The oil seal removal device of claim 1, wherein A pair of handles (8) are symmetrically arranged on the upper part of the outer wall of the cylindrical body (1) for easy gripping by the operator.
5. The oil seal removal device of claim 3, wherein The handle (8) of the drive unit (5) extends axially at opposite ends to form a small-diameter section (9) with external threads. The top block (6) is provided with an internal threaded hole that matches the outer diameter of the small diameter section (9), and the top block (6) is fixed to the small diameter section (9) by a threaded connection.
6. The oil seal removal device of claim 1, wherein The number of grippers (3) is 4.
