[0001] This invention belongs to the technical field of zipper production equipment, and specifically relates to a transmission mechanism for a zipper forming machine that is easy to disassemble and maintain, and its disassembly and assembly method. Background Technology

[0002] As a core piece of equipment in the zipper production process, the zipper forming machine generally adopts a synchronous belt transmission structure. The synchronous belt and the synchronous pulley driven by the motor transmit power, which in turn drives the various actuators to complete the zipper forming process. However, during long-term continuous operation, the synchronous belt transmission structure has obvious defects in terms of maintenance and repair: the synchronous belt needs to be replaced due to wear and tear from long-term use, but its disassembly and assembly process is complicated and cumbersome. Replacing the synchronous belt often requires disassembling the drive shaft and multiple related components, making it impossible to quickly disassemble and repair the transmission components. This not only leads to low maintenance efficiency and excessive time consumption, but also easily disrupts the normal production rhythm and affects the continuous and stable operation of the entire production line. Therefore, there is an urgent need for a zipper forming machine transmission mechanism that is easy to disassemble and maintain quickly. Summary of the Invention

The technical problem to be solved by this invention is: how to achieve quick disassembly and assembly of the synchronous belt in the transmission structure.

[0004] The above-mentioned technical objective of the present invention can be achieved through the following technical solution: a zipper forming machine transmission mechanism that is easy to disassemble and maintain, including a front drive shaft and a rear drive shaft, wherein a synchronous pulley for cooperating with synchronous belt transmission is coaxially arranged on the front drive shaft or the rear drive shaft, the front drive shaft and the rear drive shaft are both rotatably mounted on a base, the inner end of the front drive shaft and the inner end of the rear drive shaft are coaxially connected for transmission, and the inner ends of the front drive shaft and the rear drive shaft can be axially separated from each other, the inner ends of the front drive shaft and the rear drive shaft can be detachably mounted on the base, and the outer ends of the front drive shaft and the rear drive shaft are respectively mounted on the base through corresponding universal bearings.

[0005] In the aforementioned zipper forming machine transmission mechanism that facilitates quick disassembly and maintenance, the inner end of the front drive shaft and the inner end of the rear drive shaft are coaxially connected via a separable coupling.

[0006] In the aforementioned zipper forming machine transmission mechanism that facilitates quick disassembly and maintenance, a mounting seat is detachably fixed on the base, and the inner ends of the front drive shaft and the rear drive shaft are respectively rotatably mounted on the corresponding mounting seats.

[0007] In the aforementioned zipper forming machine transmission mechanism that facilitates quick disassembly and maintenance, the mounting base is threadedly connected to the base via fasteners.

[0008] In the aforementioned transmission mechanism for a zipper forming machine that facilitates quick disassembly and maintenance, the separable coupling includes a coupling body one, a coupling body two, and a transmission plate. The coupling body one is coaxially connected to the inner end of the front drive shaft, and the coupling body two is coaxially connected to the inner end of the rear drive shaft. Both the coupling body one and the coupling body two are splinedly engaged with the transmission plate, and both the coupling body one and the coupling body two can slide relative to the transmission plate along its axial direction.

[0009] In the aforementioned zipper forming machine transmission mechanism that facilitates quick disassembly and maintenance, the outer ends of the front drive shaft and the rear drive shaft are coaxially inserted into the inner rings of the corresponding universal bearings, and both the outer ends of the front drive shaft and the rear drive shaft can slide axially relative to the inner rings of the universal bearings.

At this point, the timing belt can be directly disassembled and replaced. The entire process can be completed without disassembling the drive shaft and related components, making the operation simple, convenient, and easy to maintain. Attached Figure Description

[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of the present invention. However, the present invention is not limited to these embodiments.

[0018] A transmission mechanism for a zipper forming machine that facilitates quick disassembly and maintenance, such as Figures 1 to 4 As shown, it includes a front drive shaft 1 and a rear drive shaft 2, both of which are rotatably mounted on the base 4.

[0019] The inner ends of the front drive shaft 1 and the rear drive shaft 2 can be detachably mounted on the base 4. Specifically, the base 4 is detachably fixed with mounting seats 6 corresponding to the front drive shaft 1 and the rear drive shaft 2 respectively. The inner ends of the front drive shaft 1 and the rear drive shaft 2 are rotatably mounted on the corresponding mounting seats 6. The mounting seats 6 are threadedly connected to the base 4 by fasteners 7. In this embodiment, the fasteners 7 are preferably bolts and there are at least two of them, which not only ensures the stable connection between the mounting seats 6 and the base 4, but also facilitates the quick assembly and disassembly of the mounting seats 6.

[0020] Each mounting base 6 is provided with a support bearing 8. The inner end of the front drive shaft 1 and the inner end of the rear drive shaft 2 are respectively coaxially fixed with the inner ring of the corresponding support bearing 8, so that the front drive shaft 1 or the rear drive shaft 2 can rotate relative to the mounting base 6.

[0021] To ensure axial positioning between the front drive shaft 1 or the rear drive shaft 2 and the corresponding support bearing 8, at least two corresponding retaining rings 9 are provided at intervals on both the front drive shaft 1 and the rear drive shaft 2. The two retaining rings 9 are located on both sides of the axial direction of the support bearing 8 and clamp the inner ring end face of the support bearing 8 together. The cooperation of the two retaining rings 9 restricts the axial movement of the front drive shaft 1 or the rear drive shaft 2 relative to its corresponding support bearing 8, thereby ensuring that the relative axial position of the front drive shaft 1 or the rear drive shaft 2 and its corresponding support bearing 8 is stable during operation.

[0022] It should be noted that when it is necessary to disconnect the inner end of the front drive shaft 1 or the inner end of the rear drive shaft 2 from the base 4, simply rotate the fastener 7 to remove it, and the mounting base 6, the support bearing 8, and the corresponding inner end of the front drive shaft 1 or the inner end of the rear drive shaft 2 can be moved simultaneously.

[0023] The inner end of the front drive shaft 1 is coaxially connected to the inner end of the rear drive shaft 2, and the inner ends of the front drive shaft 1 and the rear drive shaft 2 can be separated relative to each other along the axial direction.

[0024] In this embodiment, the inner end of the front drive shaft 1 and the inner end of the rear drive shaft 2 are coaxially connected by a separable coupling 5. Specifically, the separable coupling 5 includes a coupling body 1 51, a coupling body 2 52, and a transmission plate 53. The coupling body 1 51 is coaxially connected to the inner end of the front drive shaft 1, and the coupling body 2 52 is coaxially connected to the inner end of the rear drive shaft 2. Both the coupling body 1 51 and the coupling body 2 52 are splinedly engaged with the transmission plate 53, and both the coupling body 1 51 and the coupling body 2 52 can slide relative to the transmission plate 53 along its axial direction.

[0025] Specifically, the transmission plate 53 has several keyways 12, and the coupling body 1 51 and the coupling body 2 52 have key teeth 11. The key teeth 11 on the coupling body 1 51 and the key teeth 11 on the coupling body 2 52 are inserted and removed into the corresponding keyways 12. The keyways 12 and the key teeth 11 are adapted to each other. The number of key teeth 11 on the coupling body 1 51 plus the number of key teeth 11 on the coupling body 2 52 is the same as the number of keyways 12.

[0026] During normal operation, the front drive shaft 1 and the rear drive shaft 2 are connected by a coupling body 1 51, a transmission plate 53, and a coupling body 2 52 to transmit power, thus ensuring that the front drive shaft 1 and the rear drive shaft 2 rotate synchronously. When it is necessary to disconnect the connection between the front drive shaft 1 and the rear drive shaft 2, simply pull the front drive shaft 1 or the rear drive shaft 2 outward along the axial direction. At this time, the key teeth 11 on the coupling body 1 51 or the key teeth 11 on the coupling body 2 52 disengage from the keyway 12 on the transmission plate 53, and the coupling body 1 51 or the coupling body 2 52 separates from the transmission plate 53, thereby achieving the axial separation of the front drive shaft 1 and the rear drive shaft 2. The whole process does not require disassembling any fasteners or using other auxiliary tools. The operation is simple and the disassembly is convenient, effectively improving the efficiency of disassembly and maintenance.

[0027] The outer ends of the front drive shaft 1 and the rear drive shaft 2 are respectively mounted on the base 4 via corresponding universal bearings 10. Specifically, the outer ring of the universal bearing 10 is fixed on the base 4, and the outer ends of the front drive shaft 1 and the rear drive shaft 2 are coaxially passed through the inner ring of the corresponding universal bearing 10. The outer ends of the front drive shaft 1 and the rear drive shaft 2 can slide axially relative to the inner ring of the universal bearing 10. Through the action of the universal bearing 10, the inner end of the front drive shaft 1 or the inner end of the rear drive shaft 2 swings laterally around the corresponding universal bearing 10.

[0028] A synchronous pulley 3 for cooperating with synchronous belt drive is coaxially mounted on the front drive shaft 1 or the rear drive shaft 2.

[0029] It should be noted that timing belts need to be replaced due to wear and tear from long-term use. In current technology, replacing a timing belt often requires disassembling the drive shaft and multiple related components, making the entire disassembly and assembly process complex, cumbersome, and inefficient. In this embodiment, the timing belt pulley 3 is coaxially mounted on the front drive shaft 1. When the timing belt needs to be disassembled, it is only necessary to first remove the corresponding fastener 7, disconnect the connection between the mounting seat 6 and the base 4 of the corresponding front drive shaft 1, then move the front drive shaft 1 axially to separate the coupling body 51 from the transmission plate 53, and finally rotate the inner end of the front drive shaft 1 around the corresponding universal joint. When bearing 10 swings laterally, the center distance between the synchronous pulley 3 on the front drive shaft 1 and the synchronous pulley 3 that is in contact with it decreases, and the tension of the synchronous belt is released. The synchronous belt can then be directly removed for replacement. Then, the inner end of the front drive shaft 1 swings laterally back to its original position, so that the inner end of the front drive shaft 1 is coaxially aligned with the inner end of the rear drive shaft 2. Then, the front drive shaft 1 is moved axially so that the key teeth 11 on the coupling body 51 are inserted into the corresponding keyways 12 on the transmission plate 53. The whole process does not require disassembly and assembly of the drive shaft and related components. The disassembly and assembly operation is simple and convenient, and easy to maintain.

[0030] It should be noted that, in another embodiment, the synchronous pulley 3 is coaxially mounted on the rear drive shaft 2. During disassembly, it is only necessary to first remove the corresponding fastener 7 to disconnect the connection between the mounting seat 6 and the base 4 of the corresponding rear drive shaft 2. Then, move the rear drive shaft 2 axially to separate the coupling body 2 52 from the transmission plate 53. Finally, swing the inner end of the rear drive shaft 2 laterally around the corresponding universal bearing 10 to reduce the center distance between the synchronous pulley 3 on the rear drive shaft 2 and the corresponding synchronous pulley 3 that is engaged in the transmission. The tension of the synchronous belt is then released, and the synchronous belt can be directly removed for replacement. Then, swing the inner end of the rear drive shaft 2 back to its original position so that the inner end of the rear drive shaft 2 is coaxially aligned with the inner end of the front drive shaft 1. Then, move the rear drive shaft 2 axially so that the key teeth 11 on the coupling body 2 52 are inserted into the corresponding keyway 12 on the transmission plate 53.

S7: Reinstall the inner end of the front drive shaft 1 or the inner end of the rear drive shaft 2 onto the base 4, specifically by reinstalling the corresponding fastener 7 so that the corresponding mounting seat 6 is connected to the base 4.
