In addition, the compact structure of the packaging equipment restricts the operating space of the workers and affects the disassembly efficiency.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A guide shaft disassembly fixture is configured to disassemble a guide shaft on a transfer tower of packaging equipment. The guide shaft disassembly fixture includes:

[0007] A motherboard and a fastener, wherein the fastener is used to fix the guide shaft to one end of the motherboard along its length;

[0019] The beneficial effects of this utility model are as follows:

[0020] This utility model provides a guide shaft disassembly fixture, which fixes the guide shaft to the main board using fasteners. A stop block and a baffle are fixed to the main board at intervals. Near the end of the main board where the guide shaft connects, a pull rod and a movable collar are located on the stop block. When the operator pushes the movable collar to impact the baffle, the main board vibrates, causing the guide shaft to vibrate. After repeated impacts of the movable collar against the baffle, the guide shaft loosens, allowing the operator to remove it by pulling the pull rod. Because the main board and guide shaft are directly connected, the vibration of the main board after the movable collar impacts the baffle is directly transmitted to the guide shaft, minimizing the impact on other parts of the packaging equipment. This significantly reduces the risk of other parts becoming loose and improves the operational safety of the packaging equipment. Furthermore, the guide shaft disassembly fixture has a simple structure, occupies little space after assembly, and can adapt to the limited operating space in packaging equipment, greatly improving the efficiency of guide shaft disassembly.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0027] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] like Figure 1 and Figure 2As shown, this embodiment provides a guide shaft disassembly fixture, configured to disassemble the guide shaft 100 on the turntable of a packaging equipment. The guide shaft disassembly fixture includes a main board 1, a fixing member 2, a baffle 4, a stop block 3, a pull rod 5, and a movable collar 6. The fixing member 2 is used to fix the guide shaft 100 to one end of the main board 1 along the length direction. The stop block 3 and the baffle 4 are both fixedly arranged on the main board 1. The stop block 3 and the baffle 4 are spaced apart along the length direction of the main board 1. The stop block 3 is close to the end of the main board 1 that is fixed to the guide shaft 100. The pull rod 5 passes through the baffle 4 and is fixedly connected to the stop block 3. The movable collar 6 is movably sleeved on the outer periphery of the pull rod 5 and placed between the stop block 3 and the baffle 4. When disassembling the guide shaft 100, the operator can use the fixing piece 2 to fix one end of the guide shaft 100 to the main board 1 along its length. Then, push the movable collar 6 to make it strike the baffle 4. Since the baffle 4 is fixedly connected to the main board 1, and the main board 1 and the guide shaft 100 are fixed by the fixing piece 2, the movable collar 6 striking the baffle 4 will cause the main board 1 to vibrate, which in turn will cause the guide shaft 100 to vibrate. After the movable collar 6 strikes the baffle 4 multiple times, the guide shaft 100 will loosen. Then, the operator can pull the pull rod 5 to remove the guide shaft 100. Because the main board 1 and the guide shaft 100 are directly connected, when the movable collar 6 strikes the baffle 4, the vibration of the main board 1 is directly transmitted to the guide shaft 100, with little impact on other parts in the packaging equipment. This significantly reduces the risk of other parts in the packaging equipment becoming loose and improves the operational safety of the packaging equipment. At the same time, the guide shaft disassembly fixture has a simple structure, occupies little space after assembly, and can adapt to the narrow operating space in the packaging equipment, greatly improving the efficiency of the operator in disassembling the guide shaft 100.

[0031] In this embodiment, the block 3 and the baffle 4 can be welded to the motherboard 1 or fixed to the motherboard 1 by bolts, and no specific limitation is made here.

[0032] The turret includes at least three guide shafts 100. Exemplarily, the main board 1 has a protrusion 11 and two positioning grooves 12, located on both sides of the protrusion 11 along its length. The protrusion 11 has at least one positioning hole 111. The guide shafts 100 located on both sides of the turret are placed in the positioning grooves 12, and the guide shaft 100 located in the middle region of the turret passes through the positioning hole 111. The fixing member 2 is used to fix the guide shafts 100 in the positioning grooves 12 and the positioning holes 111. By setting the protrusion 11 and the positioning grooves 12, the fixed positions of the guide shafts 100 and the main board 1 can be positioned, ensuring a reasonable arrangement between them. If the turret includes three or more guide shafts 100, a corresponding number of positioning holes 111 can be provided on the protrusion 11 to ensure a reasonable arrangement between the multiple guide shafts 100 and the main board 1. The specific number of positioning holes 111 is not limited here.

[0033] Exemplarily, the fixing member 2 includes a first locking member. The protrusion 11 has a fixing hole 112 communicating with the positioning hole 111. After the first locking member is threadedly connected to the fixing hole 112, it abuts against the guide shaft 100, thus fixing the guide shaft 100 in the positioning hole 111. Specifically, the fixing hole 112 has an internal thread, and the first locking member has an external thread. The external thread of the first locking member and the internal thread of the fixing hole 112 are threadedly connected to each other. As the first locking member is turned, it abuts against the guide shaft 100. The threaded connection between the first locking member and the fixing hole 112 ensures that the first locking member securely fixes the guide shaft 100 in the positioning hole 111. In this embodiment, the first locking member can be a bolt. Furthermore, the fixing component 2 also includes a second locking component and two cover plates 21. The two cover plates 21 respectively cover two positioning grooves 12. The second locking component is used to lock the cover plates 21 to the main board 1, thus enabling the cover plates 21 and the second locking component to clamp and fix the guide shafts 100 on both sides of the turret within the positioning grooves 12 of the main board 1. Specifically, the cover plates 21 have mounting holes on both sides, and the main board 1 has corresponding mounting holes. The second locking component passes through the mounting holes and locks itself within the mounting holes. Specifically, the mounting holes have internal threads, and the second locking component has external threads. Through the mutual engagement of the internal and external threads, the second locking component can be locked within the mounting holes. In this embodiment, the second locking component can be a bolt.

[0034] In another embodiment, the fastener 2 can also be a strong adhesive, which fixes the motherboard 1 to the guide shaft 100 by gluing. After the operator removes the guide shaft 100, an adhesive remover can be used to separate the guide shaft 100 from the motherboard 1, and the remaining strong adhesive on the guide shaft 100 and the motherboard 1 can be wiped off. As long as the guide shaft 100 and the motherboard 1 can be fixed, there are no specific restrictions on the choice of the fastener 2.

[0035] For example, the stop 3 includes a connecting hole 31. The pull rod 5 passes through the baffle 4 and is fixedly connected to the connecting hole 31. The connecting hole 31 can position the installation position of the pull rod 5. Preferably, the orthogonal projection of the axis of the connecting hole 31 on the motherboard 1 coincides with the central axis of the motherboard 1. This ensures that the pull rod 5, after being assembled with the baffle 4, is positioned directly above the central axis of the motherboard 1. When the worker pulls the guide shaft 100 outward through the pull rod 5, the worker pulls the main body from the centerline direction of the motherboard 1, making the pulling process easier and faster, and making the design of the guide shaft disassembly fixture more reasonable. Specifically, the connecting hole 31 is provided with an internal thread, and the pull rod 5 is provided with an external thread. The external thread and the internal thread are threadedly connected to each other to fix the pull rod 5 to the stop 3. The baffle 4 includes a through hole, which is opposite to the connecting hole 31. The pull rod 5 passes through the through hole and is threadedly connected to the connecting hole 31, which makes it easier for the worker to assemble the guide shaft disassembly fixture.

[0036] Preferably, the end of the pull rod 5 away from the stop block 3 is provided with a handle 51, which makes it easier for workers to remove the guide shaft 100 by pulling the pull rod 5, and further improves the rationality of the guide shaft disassembly tooling design.

[0037] Preferably, the pull rod 5 has a protrusion 52 at one end near the stop 3, and the movable collar 6 is located between the protrusion 52 and the baffle 4. This limits the range of motion of the movable collar 6, preventing it from frequently and forcefully impacting the stop 3 or baffle 4 when the operator is handling the guide shaft disassembly fixture, thus protecting the stop 3 and baffle 4. In another embodiment, a rubber collar can be fitted around the outer periphery of the pull rod. The rubber collar can abut against the movable collar 6, and its position on the pull rod 5 is adjustable. The operator can adjust the position of the rubber collar according to operational needs, thereby adjusting the range of motion of the movable collar 6 and further improving the rationality of the guide shaft disassembly fixture design.

[0038] In this embodiment, the movable collar 6 is made of rubber or metal. A movable collar 6 made of rubber or metal can make the transmission of vibration force more stable.

[0039] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
