[0022] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0023] like Figure 1-Figure 4 As shown, the embodiment of the present application provides a pin disassembly tool for a cigarette packaging machine, which serves as an auxiliary tool, preferably as a disassembly tool for the pin 91 on the cigarette packaging machine. When the cigarette packaging machine performs the packaging process, it is necessary to package the cigarettes into boxes, then package the cigarette boxes into strips, and then package the cigarette strips into boxes. During this period, a variety of packaging process steps need to be completed. For this purpose, a plurality of groups of cam connecting rods 90 are provided in the cigarette packaging machine to complete the driving of related components in various packaging process steps. For the connecting rod 90, the two adjacent connecting rods 90 are rotatably connected together by the pin 91 and the bearing 92. As the equipment runs for a long time, the equipment needs to be regularly repaired and maintained. For example, the pin 91 on the connecting rod 90 needs to be disassembled for grinding. Lubrication, etc. The currently commonly used method for disassembling the pin 91 is: a coaxial threaded hole 910 is set at the end or the entire length of the pin 91, and a screw is screwed into the threaded hole 910, and then the exposed part of the screw is clamped with pliers, and the pin 91 is removed by knocking, pulling the pliers, or using the local structure on the connecting rod 90 as a lever fulcrum of the pliers. This operation method is more troublesome, and it is time-consuming and labor-intensive to directly rely on the strength of the hand to remove the pin 91. Moreover, when using the connecting rod 90 as a fulcrum, it is easy to damage or even deform the connecting rod 90. The cigarette packaging machine pin 91 disassembly tool provided in this application is intended to improve the convenience of disassembling the pin 91 in the cigarette packaging machine equipment, and avoid damage to the connecting rod 90 and other components where the pin 91 is located.

[0024] The disassembly tool of the pin shaft 91 of the cigarette packaging machine includes a bracket 100 and a screw member 200, which is used to abut against the mounting component of the pin shaft 91. For example, when the two connecting rods 90 are swung and connected by the pin shaft 91 and the bearing 92, the bracket 100 is used to abut against the position of the connecting rod 90 near the pin shaft hole 93. The bracket 100 is provided with a first abutting portion 101, and the screw member 200 has a first end and a second end. The first end of the screw member 200 is provided with an external thread, and the end of the pin shaft 91 is provided with an axial threaded hole 910. Under the action of the external thread on the first end, the first end of the screw member 200 can be screwed into the threaded hole 910 at the end of the pin shaft 91, and the second end of the screw member 200 is provided with an axial threaded hole 910. There is a second abutment 201. When the first end of the screwing member 200 is screwed into the threaded hole 910 of the pin shaft 91, the screwing member 200 gradually moves in the direction close to the pin shaft 91. When the screwing member 200 moves toward the pin shaft 91, the second abutment 201 can abut against the first abutment 101, thereby limiting the screwing member 200 from continuing to move toward the pin shaft 91. In this way, if the screwing member 200 continues to be screwed, under the reaction force, the screwing member 200 can pull out the pin shaft 91 installed in the pin shaft hole 93. In this way, the pin shaft 91 is pulled out by screwing the thread, which is convenient and labor-saving to operate, and the force is concentrated on the pin shaft hole 93 of the connecting rod 90, which will not cause deformation of the connecting rod 90.

[0025] Preferably, the screwing member 200 is a long round rod-shaped structure, and the two ends of the screwing member 200 along the length direction are respectively a first end and a second end. An external thread is provided on the outer periphery of the first end, and a driving assembly is provided on the second end. The driving assembly is used to screw the screwing member 200, and the second abutment portion 201 is provided on the driving assembly.

[0026] In one example, the drive assembly includes a base 31, the outer periphery of the base 31 extends out of the outer periphery of the screw member 200 along the radial direction of the screw member 200, or in other words, the outer periphery of the base 31 is larger than the outer periphery of the screw member 200, and a step structure is formed at the connection between the base 31 and the screw member 200 to form a second abutment portion 201. A limiting member is provided on the base 31, and the limiting member is used to screw the screw member 200. For example, the limiting member can be a radial groove to facilitate screwing by a screwdriver, or a polygonal outer periphery structure to facilitate screwing by a wrench. Preferably, the limiting member includes a wrench. The lever 32 is provided at the other end of the base 31, and the lever 32 is provided at one end of the base 31. Preferably, there are two levers 32. The base 31 is in the shape of a cone. The larger end of the base 31 is coaxially connected to the second end of the screw member 200. The larger end of the base 31 extends radially outward from the outer periphery of the screw member 200 to form the second abutting portion 201. The lever 32 is centrally symmetrically provided at the other end of the base 31. The lever 32 is a flat structure, and the plane where the lever 32 is located passes through the axis of the screw member 200, which is convenient for manual screwing.

[0027] In one embodiment, a through window 300 is provided on the first abutting portion 101, and the through window 300 is used for the screwing member 200 to pass axially and movably. After the bracket 100 is abutted against the mounting component of the pin shaft 91, the axis of the pin shaft 91 passes through the through window 300, and the screwing member 200 can movably and axially pass through the through window 300, and then the screwing member 200 is screwed so that the first end of the screwing member 200 is screwed into the threaded hole 910 at the end of the pin shaft 91, thereby facilitating the positioning of the screwing member 200 and the pin shaft 91. In this embodiment, along the axial direction of the screwing member 200, the projected area of ​​the through window 300 is smaller than the projected area of ​​the second abutting portion 201. Thus, when the screwing member 200 passes through the through window 300, it is also convenient for the second abutting portion 201 and the first abutting portion 101 to press against each other and limit the fit.

[0028] More preferably, the through window 300 is a hole-type structure. When the bracket 100 abuts against the mounting component of the pin shaft 91, the through window 300 and the pin shaft 91 are axially aligned, and then the screw member 200 is extended through the through window 300 and screwed, and the first end of the screw member 200 is screwed into the threaded hole 910 at the end of the pin shaft 91, and then the screw member 200 is continued to be screwed, and the first abutting portion 101 and the second abutting portion 201 are abutted against each other, and then the screw member 200 is screwed again, so that the pin shaft 91 can be gradually pulled out of the pin shaft hole 93.

[0029] In this embodiment, the bracket 100 is a cylindrical structure with openings at both ends. The first abutment portion 101 is arranged at one end of the bracket 100. The first abutment portion 101 is sealed at the opening at one end of the bracket 100 and is formed on the first abutment portion 101 through a window 300. The window 300 is connected to the bottom cavity of the bracket 100, so that the screw member 200 can movably pass through the window 300 and the internal cavity of the bracket 100. For the internal cavity of the bracket 100, when the pin shaft 91 is pulled outward, the internal cavity of the bracket 100 can provide axial movement for the pin shaft 91, that is, the pin shaft 91 can movably and axially enter the internal cavity of the bracket 100.

[0030] More preferably, the bracket 100 is a cylindrical structure with two ends open, the first abutting portion 101 is provided at one end opening of the bracket 100, the through window 300 is provided through the first abutting portion 101, the through window 300 and the bracket 100 are coaxially arranged, the end of the bracket 100 without the first abutting portion 101 is abutted against the mounting component of the pin 91, so that the pin 91 is projected in the internal cavity of the bracket 100, and the bracket 100 and the pin 91 are coaxial, and then the first end of the screw member 200 with the external thread is sequentially passed through the coaxial through window 300 and the bracket 100. The screw part 200 is screwed into the threaded hole 910 at the end of the pin shaft 91, and then the screw part 200 is continued to be screwed. The outer diameter of the end where the base 31 and the screw part 200 are connected is larger than the aperture of the window 300, and the base 31 cannot pass through the window 300, so that the first abutting portion 101 and the second abutting portion 201 abut against each other. Then the screw part 200 is screwed again, and the first end of the screw part 200 is continued to be screwed into the threaded hole 910, so that the pin shaft 91 can be pulled out, and the pulled-out part of the pin shaft 91 enters the internal cavity of the bracket 100.

[0031] In this embodiment, the screw member 200 and the bracket 100 are coaxial, and the screw member 200 and the pin 91 are also coaxial. The support and limiting stability of the bracket 100 is high, and the end face of the bracket 100 is circumferentially abutted against the pin 91 mounting component, which will not cause structural damage to the mounting component of the pin 91. The mounting component of the pin 91 is used as the connecting rod 90 for explanation. When disassembling, the end of the bracket 100 can abut against the outer periphery of the pin hole 93 of the connecting rod 90, and the bracket 100 and the pin hole 93 are coaxial. Since a bearing 92 is also provided between the pin 91 and the bracket 100, the bearing 92 is installed in the pin hole 93, and the pin 91 is installed in the bearing 92, the end of the bracket 100 can also be able to extend into the pin hole 93 and abut against the axial end face of the bearing 92, as shown in FIG. Figure 4 As shown, the pin 91 is removed from the bearing 92. Figure 4 The figure only schematically shows the usage status of the disassembly tool, and the size and matching status of each component can be determined according to actual conditions.

[0032] More preferably, an adjusting sleeve 400 is sleeved on the other end of the bracket 100 opposite to the end where the first abutting portion 101 is provided. The adjusting sleeve 400 is a cylindrical structure with openings at both ends, and the adjusting sleeve 400 is threadedly connected to the bracket 100. In this embodiment, the effect achieved by the adjusting sleeve 400 is that the support height of the screw member 200 can be adjusted. The adjusting sleeve 400 is threadedly connected to the outer side of the end of the bracket 100. The adjusting sleeve 400 and the first abutting portion 101 are respectively provided at both ends of the bracket 100. In this way, by screwing the adjusting sleeve 400, the adjusting sleeve 400 and the bracket 100 form an axially retractable structure, which is convenient for adjusting the overall axial height to adapt to the pin shaft 91 of different assembly conditions.
