Detailed implementation manners

[0036] The technical solutions of the present utility model will be clearly and completely described below in conjunction with specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than 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 efforts shall fall within the protection scope of the present utility model.

[0037] The embodiment of the present utility model specifically provides a pressing device for a bag-making machine. Please refer to Figure 1 , which includes a mounting base 1, a pressing roller 2 and a driving assembly 3.

[0038] Among them, the pressing roller 2 is arranged on the mounting base 1. The pressing roller 2 is arranged in two places in an up-and-down distribution manner to press the fabric. The pressing roller 2 includes a detachable roller 4 and an adjusting assembly 5. Both ends of the detachable roller 4 are connected to the adjusting assembly 5, so as to quickly load and unload the detachable roller 4 through the adjusting assembly 5. Thus, after the surface of the detachable roller 4 is worn, it can be quickly taken out from the adjusting assembly 5 for replacement, so as to improve the operation convenience, save raw materials and reduce costs.

[0039] Among them, the driving assembly 3 is connected to the adjusting assembly 5 to provide the driving force required for the loading and unloading of the detachable roller 4, so as to achieve the purpose of semi-automatic operation and save the operation intensity of workers.

[0040] Furthermore, please refer to Figure 2 , the adjusting assembly 5 includes a telescopic column 51 connected to both ends of the detachable roller 4, a support cylinder 52 rotatably matched with the mounting base 1 on the outside, and a fixing assembly connected to the detachable roller 4 and the telescopic column 51. Through the fixing assembly, the telescopic column 51 can be quickly installed and separated from the detachable roller 4.

[0041] Specifically, the telescopic column 51 includes a side plate 511 whose outer side is in contact with the detachable roller 4, a fixed column 512 coaxially fixed to one end of the side plate 511, a sliding column 513 fixedly connected to the other end of the fixed column 512, and a force-receiving disc 514 fixed to the outside of the fixed column 512. The fixed column 512 cooperates with the driving assembly 3 through the force-receiving disc 514, so that the driving assembly 3 can drive the fixed column 512 to move by applying force to the force-receiving disc 514.

[0042] Among them, please refer to Figure 3 , the support cylinder 52 includes a fixed cylinder 521 whose outer side is rotatably connected to the mounting base 1, a chute 522 opened inside the fixed cylinder 521, and a spring 523 whose two ends are fixedly connected to the chute 522 and the sliding column 513 respectively. The spring 523 provides a reset elastic force for the sliding column 513.

[0043] During implementation, the outer contour of the sliding column 513 is in a polygonal structure, and the internal structure of the chute 522 matches the shape of the sliding column 513, so that the movement of the sliding column 513 is restricted, that is, the sliding column 513 cannot rotate circumferentially, so as to improve the stability effect of sliding left and right in the chute 522.

[0044] Furthermore, please refer to Figure 4 , there are two fixed components. The fixed component includes a plug rod 531 fixedly connected to one end of the side plate 511 and a support 532 fixed to the inner wall of the detachable roller 4. The detachable roller 4 is a hollow cylindrical structure with open ends at both ends. The other end of the plug rod 531 is inserted into the support 532, so that when the sliding column 513 drives the fixed column 512 to move away from the detachable roller 4, the plug rod 531 will be separated from the support 532, so that the detachable cylinder 4 can be directly taken out on the mounting base 1.

[0045] Among them, a guide rail 524 is provided on the inner wall of the chute 522. The inner wall of the guide rail 524 is slidably matched with a slider 525. The outside of the slider 525 is fixedly connected to the sliding column 513. The length of the guide rail 524 is less than the length of the fixed cylinder 521, so that the moving stroke of the sliding column 513 in the chute 522 is restricted, and the sliding column 513 is prevented from sliding out of the chute 522.

[0046] During implementation, a ramp surface is provided on the side of the force-receiving disc 514 close to the side plate 511, and the ramp surface is used for force cooperation with the driving assembly 3.

[0047] Furthermore, please refer to Figure 2 And Figure 5 , the driving assembly 3 includes an adjusting frame 31, a synchronous frame 32 fixed to the bottom end of the adjusting frame 31, and a push cylinder 33 whose output end is fixedly connected to the synchronous frame 32. The outside of the push cylinder 33 is fixed to the mounting base 1, so as to drive the synchronous frame 32 to move up and down through the push cylinder 33, so that the adjusting frame 31 can move up and down.

[0048] Among them, the adjusting frame 31 includes a bracket 311, a pushing frame 312 arranged on one side of the bracket 311 close to the force-receiving disc 514, two socket openings 313 opened on the bracket 311, and magnets 314 fixedly installed inside the socket openings 313. The bottom end of the pushing frame 312 is located above the force-receiving disc 514. The bottom end of the pushing frame 312 is in sliding fit with the inclined plane of the force-receiving disc 514. And after the pushing frame 312 is inserted into the socket opening 313, it is magnetically connected to the magnet 314. The positions of the two socket openings 313 are equidistant from the upper and lower force-receiving discs 514 respectively, so that when it is necessary to unload the detachable roller 4 above, only need to make the pushing cylinder 33 drive the pushing frame 312 to move downward, so that the bottom end of the pushing frame 312 drives the force-receiving disc 514 to expand and move through the inclined plane. When it is necessary to take out the detachable roller 4 below, the pushing frame 312 can be pulled out from the upper socket opening 313 and then inserted into the lower socket opening 313. The pushing frame 312 is made of ferromagnetic material and can be magnetically adsorbed by the magnet 314, so that the bracket 311 applies force to it stably. A guide block 11 is arranged on the inner wall of the mounting seat 1, and the outside of the bracket 311 slides up and down along the guide block 11.

[0049] The control mode of the present utility model is controlled by manually starting and closing the switch. The wiring diagram of the power element and the power supply are common knowledge in the art, and the present utility model is mainly used to protect mechanical devices, so the control mode and wiring layout of the present utility model will not be explained in detail.

[0050] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
