Description

Technical Field

[0001] This utility model relates to auxiliary tools for cigarette production equipment, and more specifically, to a tool for disassembling and assembling the forming wheel of a cigarette packaging machine. Background Technology

[0002] The existing FX2 hard-pack cigarette packaging machine in the cigarette industry uses four Allen screws to fix the carton forming wheel to the end of the rotating shaft. When repairing the equipment, replacing parts, or cleaning and maintaining it, it is sometimes necessary to disassemble the carton forming wheel. Because the carton forming wheel is relatively large and the screw mounting holes are deep, an extended Allen tool is required for disassembly and assembly. Furthermore, the carton forming wheel is heavy and rotates intermittently, generating a certain amount of impact force. Therefore, a torque wrench is needed to tighten it with greater torque during installation. Due to the deep and large diameter of the screw mounting holes on the carton forming wheel, the extended wrench cannot guarantee coaxiality with the screws when disassembling and assembling with greater torque, resulting in an angled tilt. In this case, the Allen wrench of the extended wrench does not fit tightly with the Allen wrench hole of the screw, and the Allen wrench hole of the screw is prone to deformation and slippage, making disassembly difficult and greatly increasing maintenance time. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a tool for disassembling and assembling the forming wheel of a cigarette packaging machine, so as to avoid the deformation and slippage of the screw's internal hexagonal hole during the disassembly and installation of the forming wheel, making maintenance convenient and quick and saving maintenance time.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A tool for disassembling and assembling the forming wheel of a cigarette packaging machine is provided for disassembling and assembling the screws at the end of the forming wheel. The forming wheel has a countersunk hole for the screw head to be recessed. The tool includes an extension rod and a force rod. The extension rod includes an extension rod body. One end of the extension rod body is provided with an external hexagonal head that matches the internal hexagonal hole of the screw head. The other end of the extension rod body is connected to a force rod perpendicular to the extension rod body. A support ring is slidably fitted on the extension rod body. The support ring is a stepped ring, with the small end of the support ring facing the external hexagonal head and matching the countersunk hole for screw installation at the end of the forming wheel.

[0006] As a preferred embodiment of the above-mentioned disassembly and assembly tool, the extension rod consists of two coaxially connected sub-rods that are detachably connected. The extension rod has a radially penetrating circular hole at its end. The first sub-rod is a stepped shaft shape, and the diameter of the circular hole is larger than the diameter of the small end of the first sub-rod but smaller than the diameter of the large end. The second sub-rod has a shaft hole at its end. The small end of the first sub-rod passes through the circular hole of the extension rod and is inserted into the shaft hole of the second sub-rod.

[0007] As a preferred embodiment of the above-mentioned disassembly and assembly tool, the extension rod body has a force-applying end with a diameter larger than that of the extension rod body at one end connected to the force-applying rod. The force-applying end and the extension rod body are connected by a conical surface with an inclined transition, and a circular hole is opened on the force-applying end.

[0008] Compared with existing technologies, the beneficial effects of this utility model are reflected in:

[0009] This utility model provides a tool for disassembling and assembling the forming wheel of a cigarette packaging machine. It features an extension rod with an external hexagonal head and a force-bearing rod perpendicular to the extension rod. By inserting the external hexagonal head into the internal hexagonal hole of a screw and rotating the force-bearing rod, the screw can be turned, thus facilitating the disassembly or installation of the forming wheel from the rotating shaft. Simultaneously, a support ring is slidably fitted onto the extension rod. During operation, the small end of the support ring is inserted into the countersunk hole of the screw at the end of the forming wheel. The support ring provides full support to the extension rod, ensuring coaxiality between the extension rod and the screw. This effectively prevents the external hexagonal head from becoming misaligned and slipping due to tilting, significantly reducing the risk and difficulty of disassembly and installation, and improving work efficiency.

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] Please refer to Figures 1 to 4This embodiment provides a tool for disassembling and assembling the forming wheel of a cigarette packaging machine. It is used to disassemble and assemble the screws at the end of the forming wheel 1. The forming wheel 1 has a countersunk hole 2 at its end for the screw head to be recessed. The tool includes an extension rod and a force-applying rod. The extension rod includes an extension rod body 3. One end of the extension rod body 3 has an external hexagonal head 4 that matches the internal hexagonal hole of the screw head. The other end of the extension rod body 3 is connected to a force-applying rod perpendicular to the extension rod body 3. The extension rod body 3 has a force-applying end 5 with a diameter larger than the extension rod body 3 at the end connected to the force-applying rod. The force-applying end 5 and the extension rod body 3 are connected by a conical surface with an inclined transition. A support ring 6 is slidably fitted onto the extension rod body 3. The support ring 6 is a stepped ring, with its small end facing the external hexagonal head 4 and matching the countersunk hole 2 at the end of the forming wheel 1. The support ring 6 is slidably fitted onto the extension rod body 3 through a central hole 7.

[0017] The extension rod consists of two coaxially connected sub-rods that can be detachably connected. The first sub-rod 8 is a stepped shaft shape. The extension end 5 of the extension rod has a radially penetrating circular hole 9. The diameter of the circular hole 9 is larger than the diameter of the small end of the first sub-rod 8 but smaller than the diameter of the large end. The end of the second sub-rod 10 has a shaft hole 11. The small end of the first sub-rod 8 passes through the circular hole 9 of the extension rod and is inserted into the shaft hole 11 of the second sub-rod 10.

[0018] When using this tooling, the outer hexagonal head 4 of one end of the extension rod is inserted into the countersunk hole 2 of the screw mounting on the strip forming wheel 1 and then embedded into the inner hexagonal hole of the screw. The support ring 6 is moved axially so that the small end of the support ring 6 is engaged in the countersunk hole 2 of the screw mounting, thus completing the installation of the extension rod and the strip forming wheel 1. The small end of the first branch rod 8 is passed through the round hole 9 of the extension rod and then inserted into the shaft hole 11 of the second branch rod 10, thus realizing the installation of the force-adding rod and the extension rod. By rotating the force-adding rod, the extension rod can be rotated, which in turn drives the screw to rotate, realizing the disassembly and assembly of the strip forming wheel 1. Since the extension rod is supported by the support ring 6 throughout the disassembly and assembly process, the coaxiality of the extension rod and the screw is ensured, avoiding the phenomenon of deformation and slippage caused by the outer hexagonal head 4 being misaligned and not properly fitted with the inner hexagonal hole of the screw. This greatly reduces the risk and difficulty of disassembly and assembly, making the maintenance of the strip forming wheel 1 convenient and quick, saving maintenance time, and improving maintenance efficiency.

[0019] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
