[0002] During the production process in a cigarette factory, a cigarette packing machine completes the packing of cigarette sticks, cigarette cases, and cigarette cartons. During packing, the transfer and conveyance of cigarette cases, cigarette cartons, and cigarette boxes are carried out multiple times, and the conveyance action is completed by the chain on the cigarette packing machine. Under the long-term operation condition of the equipment, the chain links are prone to deformation under the influence of external forces. Therefore, it is necessary to replace the deformed links. Usually, when replacing the links, the operator first needs to knock out the pin connecting the links. The operator holds a punch in one hand and a hammer in the other hand, places the punch against one end of the pin, adjusts the position of the chain so that the other end of the pin is suspended, and then uses the hammer to strike the punch to remove the pin. After replacing the link, the pin also needs to be installed by knocking during reinstallation. This operation method is not convenient enough and is prone to injuring the operator's hand, presenting certain potential safety hazards. Summary of the Utility Model

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the present application.

[0025] As Figures 1-5 shown, an embodiment of the present application provides a disassembly and assembly tooling for the conveying chain of a cigarette packaging machine. As an auxiliary tool, it is used to disassemble, replace, and reinstall the chain links in the cigarette packaging machine. During the operation of the cigarette packaging machine, the transfer and conveyance of cigarette cartons, cigarette strips, cigarette cases, etc. are mostly completed through the conveying chain. Under the long-term operation of the equipment, the chain links are prone to deformation under the action of external forces. Therefore, it is necessary to disassemble and replace the deformed chain links. When disassembling, the operator needs to hold a punch with one hand and a hammer with the other hand, place the punch against one end of the pin shaft between the chain links, and make the other end of the pin shaft in a suspended state. Then, use the hammer to strike the punch, and rely on the impact force to knock the pin shaft out of the pin hole. After replacing the new chain link, the pin shaft also needs to be reinstalled into the pin hole by relying on the hammer strike. This operation method is not convenient enough. During the knocking process, the punch is prone to deviate from the pin shaft, and it is easy to hurt the operator's hand during the knocking process, presenting certain safety hazards. The disassembly and assembly tooling for the conveying chain of the cigarette packaging machine provided by the present application aims to improve the convenience and safety of replacing the links.

[0026] The disassembly and assembly tooling for the conveying chain of the cigarette packing machine includes a connecting arm 100, a positioning frame 200 and a driving assembly. The driving assembly is connected to the connecting arm 100 and the positioning frame 200 respectively. That is, the connecting arm 100 is connected to the positioning frame 200 through the driving assembly. A part of the connecting arm 100 is used to extend into the pin hole of the chain link. A limiting part 201 is arranged on the positioning frame 200. The positioning frame 200 can be limited in the first direction with the chain through the limiting part 201. That is, under the action of the limiting part 201, relative fixation in the first direction can be achieved between the positioning frame 200 and the chain to be disassembled and assembled.

[0027] Under the driving action of the driving assembly, the connecting arm 100 moves relative to the positioning frame 200 along the first direction. The first direction is the axial direction of the pin. When the connecting arm 100 moves, a part of the connecting arm 100 can extend into the pin hole, and then the pin in the pin hole is pushed out to realize the disassembly of the chain link. Similarly, during installation, the connecting arm 100 moves relative to the positioning frame 200 in the first direction, and the connecting arm 100 gradually pushes the pin into the pin hole.

[0028] In one embodiment, as Figure 5 shown, the driving assembly includes a first sleeve 31 and a second sleeve 32 arranged in parallel. The outer side wall of the first sleeve 31 is welded to the outer side wall of the second sleeve 32. The axis of the first sleeve 31 and the axis of the second sleeve 32 are parallel to each other. Both the positioning frame 200 and the connecting arm 100 are slender rods. One end of the positioning frame 200 is fixedly connected in the first sleeve 31. The other end of the positioning frame 200 extends along the first direction, and a 90-degree hook can be arranged at the other end of the positioning frame 200. By hooking the hook on one side of the chain, mutual limitation between the positioning frame 200 and the chain is realized. One end of the connecting arm 100 can be movably extended into the second sleeve 32. The connecting arm 100 and the second sleeve 32 are connected by threads. When the connecting arm 100 is screwed, the other end of the connecting arm 100 can move relative to the positioning frame 200, and then the end of the connecting arm 100 extends into the pin hole of the chain link, pushing the pin out of the pin hole or pushing the pin back into the pin hole again. In this embodiment, the hook on the positioning frame 200 hooks on one side of the chain. When the connecting arm 100 moves, it pushes the pin on the other side of the chain, and then the pin can be pushed out. In this embodiment, pliers can be used or a nut can be coaxially welded on the connecting arm 100 to rotate the connecting arm 100. In addition, in this embodiment, when the positioning frame 200 is in a horizontal state, the 90-degree hook formed at the end of the positioning frame 200 is not vertically upward, so that the extension line of the connecting arm 100 does not pass through the hook. In this way, when the pin is pushed out, the hook is prevented from interfering with the pin.

[0029] Preferably, the driving assembly includes a base. The connecting arm 100 is movably arranged on the base along a first direction. The positioning frame 200 is fixedly arranged on the base. A lever 400 is arranged on the base. A plurality of tooth grooves 50 are arranged on the connecting arm 100 at intervals along the length direction of the connecting arm 100. When the lever 400 moves, it can cooperate with the tooth grooves 50 to move the connecting arm 100 along the first direction.

[0030] In this embodiment, the middle of the lever 400 is hinged to the base. A first clamping block 61 is movably arranged on one of the movable ends of the lever 400. An elastic member is arranged between the first clamping block 61 and the lever 400. Under the action of the elastic member, the first clamping block 61 and the connecting arm 100 are elastically abutted against each other. When the lever 400 swings back and forth, the first clamping block 61 and the tooth grooves 50 cooperate to move the connecting arm 100 step by step. Preferably, the base is arranged in a grip-like shape for easy gripping. The lever 400 has a certain length. The base includes a first side wall 71, a second side wall 72 and a third side wall 73. The first side wall 71 and the second side wall 72 are parallel, spaced apart and opposite to each other. The third side wall 73 is connected between the first side wall 71 and the second side wall 72, so that the overall shape of the base is roughly flat. The first side wall 71, the second side wall 72 and the third side wall 73 enclose an internal cavity. The lever 400 is hinged between the first side wall 71 and the second side wall 72. One end of the lever 400 is connected to the first clamping block 61, and the other end of the lever 400 extends out of the above internal cavity. Furthermore, an operator can repeatedly swing the lever 400 back and forth by hand, so that the first clamping block 61 on the lever 400 engages with the tooth grooves 50 on the connecting arm 100 to drive the connecting arm 100 to move.

[0031] Preferably, the first clamping block 61 is hinged to the lever 400. The first clamping block 61 can swing relative to the lever 400. The elastic member arranged between the first clamping block 61 and the lever 400 can be a torsion spring, so that the first clamping block 61 can elastically swing and elastically abut against the bottom side of the connecting arm 100.

[0032] In this embodiment, a positioning disc 800 is provided on the same side of the first side wall 71 and the second side wall 72. The positioning disc 800 and the third side wall 73 are opposite in position and spaced apart. The connecting arm 100 is movably penetrated through the positioning disc 800 and the third side wall 73. The connecting arm 100 is an oval rod. One end of the positioning frame 200 is fixedly provided on the positioning disc 800. The positioning frame 200 is also an oval rod, which is convenient for the production of components. The limiting portion 201 is provided at the other end of the positioning frame 200. Taking the horizontal state of the positioning frame 200 as an example for illustration, the right end of the positioning frame 200 is connected to the positioning disc 800. The connecting arm 100 and the positioning frame 200 are parallel to each other. The protruding end of the lever 400 is inclined towards the direction of the positioning frame 200. By pressing the lever 400 by hand, the first block 61 on the lever 400 abuts against the tooth groove 50 and moves the connecting arm 100 to the left. In this way, the connecting arm 100 can move to the right relative to the positioning frame 200. During use, the limiting portion 201 is relatively fixed to the chain, and the connecting arm 100 is aligned with the pin shaft. Then, by repeatedly pressing the lever 400, the connecting arm 100 can be made to push the pin shaft to the left until the pin shaft is pushed out.

[0033] The connecting arm 100 axially and circumferentially movably penetrates through the third side wall 73 and the positioning disc 800.

[0034] Preferably, a second block 62 is movably provided on the base. An elastic member is provided between the second block 62 and the base. Under the action of the elastic member, the second block 62 and the connecting arm 100 are elastically abutted against each other. The second block 62 abuts against the connecting arm 100 and is engaged with the tooth groove 50 to limit the reverse movement of the connecting arm 100, which is beneficial to driving the connecting arm 100 to move to the left. In this embodiment, the second block 62 is hinged between the first side wall 71 and the second side wall 72, so that the first block 61 can swing. A torsion spring can be provided between the second block 62 and the first side wall 71. Under the elastic action of the torsion spring, the movable end of the second block 62 elastically abuts against the bottom side of the connecting arm 100, realizing the engagement between the second block 62 and the tooth groove 50 on the connecting arm 100.

[0035] Preferably, the tooth grooves 50 on the connecting arm 100 are evenly arranged on the outer wall of the connecting arm 100 along the axial direction of the connecting arm 100, and the multiple tooth grooves 50 are located on the same side of the outer periphery of the connecting arm 100. In this way, when the connecting arm 100 is driven to move to the left by means of the lever 400, the tooth grooves 50 on the connecting arm 100 face downward, and the first clamping block 61 on the lever 400 is normally engaged with the tooth grooves 50 to drive the connecting arm 100 to the far right. Alternatively, after the connecting arm 100 pushes out the pin shaft, when the connecting arm 100 needs to be reset to the right, the connecting arm 100 is axially rotated so that the tooth grooves 50 on the connecting arm 100 are 0 upwards, so that the first clamping block 61 and the second clamping block 62 are disengaged from the tooth groove 50, and the connecting arm 100 can be smoothly moved to the right and reset. In this embodiment, the first clamping block 61 and the second clamping block 62 are both located below the connecting arm 100, and the first clamping block 61 and the second clamping block 62 are both against the bottom of the connecting arm. As for the shape of the tooth groove 50, the left side of the tooth groove 50 is parallel to the axial direction of the connecting arm 100, and the right side of the tooth groove 50 and the axial direction of the connecting arm 100 are at a non-90 degree angle, so that the tooth groove 50 has an outwardly flared structure, which is convenient for forming a snap fit and facilitating the connecting arm 100 to move to the left.

[0036] The limiting portion 201 is arranged on the side of the positioning frame 200 facing the connecting arm 100, and one side of the limiting portion 201 is connected to the positioning frame 200, and the other side of the limiting portion 201 extends toward the direction of the connecting arm 100. Preferably, the extension line of the portion of the connecting arm 100 that can be inserted into the chain link pin shaft hole passes through the limiting portion 201, and a window 2011 for the pin shaft to pass through is provided on the limiting portion 201, so that it is convenient to locate the position of the pin shaft. When in use, the connecting arm 100 is first moved to the right, and the limiting portion 201 on the positioning frame 200 is hooked on the left side in the width direction of the chain, and the limiting portion 201 is located at the position of the pin shaft, and the axial projection of the pin shaft is located in the window 2011, and then the connecting arm 100 is manually pushed to the left so that the left end of the connecting arm 100 is against the same part on the chain. The right end of the pin shaft, and then the lever 400 is pressed reciprocally, so that the first block 61 on the lever 400 gradually drives the connecting arm 100 to the left until the connecting arm 100 pushes the pin shaft in the chain out. When the pin shaft is pushed out, it will come out of the window 2011 on the limiting part 201. After replacing the chain link and reinstalling the pin shaft, the connecting arm 100 is moved to the right to reset, so that the space between the left end of the connecting arm 100 and the limiting part 201 is sufficient to accommodate the chain width and the pin shaft length, and the limiting part 201 is hooked on the left side in the chain width direction, and then one end of the pin shaft is axially aligned with the right end of the pin shaft hole, and the connecting arm 100 is manually moved so that the left end of the connecting arm 100 is against the right end of the pin shaft, and then by repeatedly pressing the lever 400, the lever 400 drives the connecting arm 100 to move to the left until the pin shaft is pushed into the pin shaft hole.

[0037] In this way, it is convenient to position and limit the engagement between the limiting portion 201 and the chain.

[0038] In one embodiment, the limiting portion 201 is arranged in a plate shape. One end of the limiting portion 201 is connected to the positioning frame 200. The window 2011 penetrates through the limiting portion 201. The positioning frame 200 is in an oval rod-shaped structure. The axial direction of the positioning frame 200 is perpendicular to the limiting portion 201, which is convenient for the plate-shaped limiting portion 201 to engage and limit with one side in the width direction of the chain.

[0039] More preferably, the connecting arm 100 is in an oval rod shape, and the connecting arm 100 includes a first section 101 and a second section 102. Both the first section 101 and the second section 102 extend along the first direction. The first section 101 and the second section 102 are axially connected together. The first section 101 is used to extend into the pin hole of the chain link, and the second section 102 is used to be connected to the positioning frame 200 through the driving assembly. In this embodiment, the outer diameter dimension of the first section 101 is smaller than the outer diameter dimension of the second section 102, which improves the structural strength of the connection with the driving assembly and at the same time facilitates the extension of the first section 101 into the pin hole. In this embodiment, the tooth groove 50 is arranged on the same side of the second section 102. By increasing the local dimension, the influence of the setting of the tooth groove 50 on the structural strength of the connecting arm 100 is avoided.
