Description

Technical Field

[0001] This utility model relates to the field of coupling disassembly fixtures, and in particular to a coupling disassembly fixture for a cigarette packaging machine. Background Technology

[0002] The ZB45 packaging machine's second cigarette pusher primarily propels 20 formed cigarette packs from the cigarette mold box into the right-side mold box of the first wheel, completing the cigarette pack conveying process. The drive shaft coupling of the ZB45 packaging machine's second cigarette pusher requires regular maintenance. Disassembly of the coupling is time-consuming, labor-intensive, and prone to damaging surrounding components. When the drive shaft coupling of the second cigarette pusher wears down, the movement becomes unstable, leading to a series of accidents such as cigarettes not being pushed into position, damage to the cigarette mold box, and equipment collisions. Therefore, frequent disassembly and maintenance of the coupling are necessary. However, the current disassembly operation requires three people: one to hold the coupling, one to grip the copper rod, and one to use a hammer to knock out the coupling pin. Due to the limited space, removal is extremely difficult during disassembly, time-consuming, labor-intensive, and prone to damaging surrounding components.

[0003] In conclusion, developing a tooling that can assist in disassembling coupling pins and improve work efficiency is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this utility model is to provide a disassembly fixture for the coupling of a cigarette packaging machine, which solves the technical problem that the lack of auxiliary fixtures in the current coupling disassembly operation leads to low efficiency and difficult operation of the coupling pin disassembly process.

The first baffle has a top holding hole that is perpendicular to the first baffle. A top holding member is threaded into the top holding hole. The side wall of the second baffle has a relief groove that corresponds to the position of the top holding hole. By screwing on the top holding member, the pin on the end face of the coupling is pushed out.

[0007] Preferably, the first baffle includes a ring platform and a protrusion. The protrusion is disposed on the inner side wall of the ring platform, and the top holding hole is disposed on the protrusion. The arc corresponding to the axis of the top holding hole to the two sides of the ring platform is equal.

[0016] Compared to the aforementioned background technology, the cigarette packaging machine coupling disassembly fixture provided by this utility model includes: a positioning plate, on which a first baffle and a second baffle are respectively provided on both sides along its length direction. The first baffle and the second baffle are both located on the same side of the top positioning plate and are arranged parallel to each other. The side wall of the positioning plate between the first baffle and the second baffle is specifically an arc surface, the length of which is equal to the length of the coupling.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] This utility model provides a disassembly fixture for the coupling of a cigarette packaging machine. Please refer to the appendix of the instruction manual. Figures 1 to 3This application includes a positioning plate 1. A first baffle 2 and a second baffle 3 are respectively provided on both sides of the positioning plate 1 along its length. The first baffle 2 and the second baffle 3 are parallel and extend in the same direction. The side wall of the positioning plate 1 between the first baffle 2 and the second baffle 3 is specifically an arc surface 4. The length of the arc surface 4 is equal to the length of the coupling. The arc surface 4 can fit against the side wall of the coupling. The first baffle 2, the second baffle 3, and the positioning plate 1 together form a groove that can engage with the coupling, locking the axial relative freedom of this application and the coupling. A top-holding hole 24 is provided on the first baffle 2, and a clearance groove 31 is provided on the second baffle 3. The clearance groove 31 and the top-holding hole 24 are positioned in opposite directions. Correspondingly, a top-holding member is threadedly connected to the top-holding hole 24. By screwing the top-holding member, the length of the top-holding member extending into the groove is adjusted. In one embodiment of this application, the coupling is held between the first baffle 2 and the second baffle 3, so that the arc surface 4 fits tightly with the coupling, completing the engagement of the coupling disassembly fixture with the coupling. Then, the positioning plate 1 is pushed, so that the coupling disassembly fixture rotates around the axis of the coupling, so that the top-holding hole 24 and the relief groove 31 correspond to the pins on the coupling. The top-holding hole 24 corresponds to the tail of the pin, and the relief groove 31 corresponds to the head of the pin. The top-holding member is threadedly connected to the top-holding hole 24. After the top-holding member is continuously screwed, it extends into the groove and abuts against the tail of the pin, pushing the pin out of the coupling.

[0025] Please continue to refer to the instruction manual appendix. Figure 1 The first baffle 2 includes a ring platform 21 and a protrusion 22. The ring platform 21 is connected to the positioning plate 1, and the protrusion 22 is located on the end face of the ring platform 21 near the axis of the arc surface 4. Preferably, the top holding hole 24 is located on the protrusion 22, and the arc corresponding to the arc surface 4 on both sides of the axis of the top holding hole 24 is equal. This ensures that after the top holding hole 24 is connected to the pin, the force-bearing area of ​​the coupling sidewalls on both sides of the pin is equal. When the operator screws the top holding part, the top holding part is always coaxial with the pin, preventing uneven force on both sides of the top holding part and the overall skew of the coupling disassembly fixture. The thrust applied by the top holding part to the pin has a component force to push the pin out of the coupling and a component force to make the pin fit with the reserved hole of the coupling, thereby increasing the friction between the pin and the coupling and affecting the disassembly efficiency of this application.

[0026] Preferably, the support member is a bolt, and the length of the threaded section of the support member is greater than the thickness of the coupling. The support member with a longer length can ensure that the pin is fully ejected from the coupling.

[0027] Furthermore, the bottom surface of the relief groove 31 is specifically a first cylindrical surface. After the groove body and the coupling are connected, the pin head on one end face of the coupling is engaged in the relief groove 31. The first cylindrical surface fits against the side wall of the pin head, making the relief groove 31 and the pin stably set. The separation process of the pin and the coupling is more convenient. In addition, a docking groove 23 is provided on the side wall of the protrusion 22 near the second baffle 3. The extension direction of the docking groove 23 is the axial direction of the arc surface 4, and the depth of the docking groove 23 is less than the thickness of the protrusion 22. This allows the top holding hole 24 to be located inside the thicker side wall of the protrusion 22, ensuring that the top holding hole 24 has sufficient load strength and can provide sufficient holding force for the pin. Preferably, the wall surface of the mating groove 23 near the arc surface 4 is specifically a second cylindrical surface. The second cylindrical surface is used to fit against the rod portion of the pin. It should be noted that the arc corresponding to the first cylindrical surface and the second cylindrical surface is 180°. The first cylindrical surface and the second cylindrical surface are tangent to the walls on both sides of their respective axes, and the aforementioned walls extend to the end face of the second baffle 3 and the protrusion 22 on the side away from the arc surface 4. An opening for receiving the pin is formed on the second baffle 3 and the protrusion 22, so that the docking process between the relief groove 31 and the head of the pin, and between the mating groove 23 and the rod portion of the pin is smooth, further reducing the difficulty of disassembling the coupling and the pin.

[0028] Preferably, the top holding hole 24 is located at the bottom of the mating groove 23, and the axes of the top holding hole 24, the first cylindrical surface, and the second cylindrical surface coincide. When the coupling disassembly fixture with this structure pushes the pin through the top holding member, the pin is only subjected to thrust along its axial direction, avoiding increasing the friction between the pin and the pre-reserved hole of the coupling, thereby reducing the disassembly efficiency of the pin.

[0029] Please refer to the instruction manual appendix. Figure 2 A connecting hole 5 is provided on one end face of the ring platform 21, and the end face is located at any end of the arc chord corresponding to the arc surface 4. The connecting hole 5 is used to set a connector. In one embodiment of this application, the operator can set a connector between the connecting holes 5 of several coupling disassembly fixtures to form a whole. The coupling disassembly fixture group can simultaneously connect with multiple pins on the coupling, and multiple pins can be disassembled at one time, which improves the disassembly efficiency of the coupling and pins.

[0030] Preferably, the first baffle 2, the ring platform 21, and the protrusion 22 are all fan-shaped plates. The thickness of the first baffle 2 is greater than the thickness of the second baffle 3. The arc of the arc surface 4 is 80° and the radius of the arc is 43cm. The arc of the protrusion 22 is 30° and the radius of the arc is 35cm.

[0031] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0032] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
