Similarly with the first connecting hole 305, the second connecting hole 309 in the embodiment can also be a light hole or a threaded hole, and the fastener capable of being installed in the second connecting hole 309 can also be a pin, a screw or a bolt commonly used in the art.

[0036] According to the above structure provided in the embodiment, the connecting seat 304 is connected with the air cylinder 301 through the draw bar 306, so that the connecting stability is ensured, and the handbag flattening hole mechanism provided in the embodiment can be stably operated for a long time. In addition, the connecting seat 304 detachably connected with the draw bar 306 can be integrally disassembled with the blade 302, so that the maintenance of the blade 302 is facilitated, and the quality of the flattened hole 201 of the handbag flattening hole mechanism provided in the embodiment is improved.

[0037] In another embodiment of the present application, referring to Figs. 1-3 , the support seat 100 further forms a third workbench 103 between the first workbench 101 and the second workbench 102 and spaced from the first workbench 101 and the second workbench 102; the perforating assembly further comprises a guide seat 310 mounted on the third workbench 103, and the blade 302 passes through the guide seat 310 and is slidably connected with the guide seat 310. According to the above structure provided in the embodiment, the guide seat 310 slidably connected with the blade 302 can provide movement guidance for the blade 302, so that the movement stability of the blade 302 is effectively ensured, and the quality of the flattened hole 201 of the handbag flattening hole mechanism provided in the embodiment is improved.

[0038] In another embodiment of the present application, referring to Figs. 1-3 , the perforating assembly further comprises a guide rod 311 penetrating the guide seat 310, a pressing plate 312 connected at an end of the guide rod 311 away from the connecting seat 304, and a first spring 313 coaxially sleeved on the guide rod 311; the guide rod 311 is slidably connected with the guide seat 310, and the sliding direction of the guide rod 311 relative to the guide seat 310 is parallel to the sliding direction of the blade 302 relative to the guide seat 310, the pressing plate 312 is perpendicular to the movement direction of the blade 302 and forms an avoiding hole 314 for the blade 302 to pass through, the two ends of the first spring 313 abut against the connecting seat 304 and the guide rod 311 respectively, and the pressing plate 312 is closer to the die 200 than the blade 302, and the interval distance between the top end surface of the guide rod 311 and the bottom end surface of the connecting seat 304 is greater than the interval distance between the pressing plate 312 and the guide seat 310.

[0039] According to the above structure provided in the embodiment, the pressing plate 312 is closer to the concave die 200 than the blade 302 in the natural state. When the punching operation is needed, the connecting seat 304 driven by the air cylinder 301 can directly drive the blade 302 and indirectly drive the guide rod 311 to slide relative to the guide seat 310, so that the pressing plate 312 closer to the concave die 200 can first press the target bag body between the pressing plate 312 and the concave die 200, which makes the punching process of the blade 302 on the target bag body more stable and reliable, thereby facilitating to further improve the quality of the flat hole 201 of the drawstring bag punching mechanism in the embodiment. It can be understood that the interval distance between the top end surface of the guide rod 311 and the bottom end surface of the connecting seat 304 is greater than the interval distance between the pressing plate 312 and the guide seat 310, which can ensure that the connecting seat 304 drives the pressing plate 312 to press the bag opening part of the target drawstring bag on the opening of the concave die 200 under the action of the first spring 313, and the first spring 313 has sufficient elastic stroke to facilitate the blade 302 to have space to descend to complete the punching action after the pressing plate 312 presses the bag opening part of the target drawstring bag on the opening of the concave die 200. At the same time, when the connecting seat 304 rises and resets, the blade 302 is first retracted relative to the pressing plate 312 under the action of the first spring 313 to complete the action of forcibly removing the target drawstring bag from the blade 302. After the connecting seat 304 rises and resets, the second spring 315 drives the guide rod 311 to rise and drives the pressing plate 312 to rise to abut against the lower end surface of the guide seat 310 to prevent the guide rod 311 from being pulled out of the guide seat 310, which can effectively ensure the smooth punching process of the drawstring bag punching mechanism in the embodiment.

[0040] In another embodiment of the present application, please refer to Figs. 1-3 , the punching assembly further comprises a second spring 315 coaxially sleeved on the guide rod 311; the two ends of the second spring 315 abut against the guide seat 310 and the guide rod 311, respectively. According to the above structure provided in the embodiment, the second spring 315 abutting against the guide seat 310 and the guide rod 311 at both ends can automatically retract the guide rod 311 when the guide rod 311 is not subjected to external force, which facilitates the pressing plate 312 connected to the guide rod 311 to quickly return to the initial position, thereby facilitating to improve the punching efficiency of the drawstring bag punching mechanism in the embodiment. It can be understood that when the connecting seat 304 rises and resets, the force of the first spring 313 making the guide rod 311 descend is less than the force of the second spring 315 making the guide rod 311 rise, the guide rod 311 drives the pressing plate 312 to rise and reset, that is, at this time, the connecting seat 304 does not press the first spring 313, and the elastic force of the second spring 315 only bears the weight of the first spring 313, the guide rod 311 and the pressing plate 312; when the connecting seat 304 descends to press the first spring 313, the elastic force of the first spring 313 is greater than the elastic force of the second spring 315.

[0041] In another embodiment of the present application, referring to Figs. 1-3 The guide rods 311, the first springs 313 and the second springs 315 are correspondingly provided with at least two groups and are symmetrically arranged about the axial direction of the blade 302. According to the above structure provided in the embodiment, the two groups of the guide rods 311, the first springs 313 and the second springs 315 symmetrically arranged about the axial direction of the blade 302 can effectively ensure the stability of the movement of the pressing plate 312, which is beneficial to further improve the quality of the flat hole 201 of the flat hole mechanism of the handbag in the embodiment.

[0042] In another embodiment of the present application, referring to Figs. 1-3 The punching assembly further comprises a screw rod 316, a positioning plate 317 connected to the end of the screw rod 316, a nut 318 threadedly connected to the screw rod 316 and a clamping seat 319 connected to the support base 100; the nut 318 is clamped between the clamping seat 319 and the support base 100 and can rotate about its central axis, the screw rod 316 is perpendicular to the moving direction of the blade 302 and penetrates through the support base 100, and the positioning plate 317 is located between the second workbench 102 and the third workbench 103 and is parallel to the moving direction of the blade 302.

[0043] According to the above structure provided in the embodiment, when the nut 318 rotates about its central axis, the screw rod 316 can be driven to move along its axial direction, so that the positioning plate 317 connected to the screw rod 316 and located between the first workbench 101 and the third workbench 103 can move along the axial direction of the screw rod 316. Since the axial direction of the screw rod 316 is also perpendicular to the moving direction of the blade 302, moving the positioning plate 317 by the screw rod 316 can make the flat hole mechanism of the handbag in the embodiment suitable for punching operation of different specifications of target bag bodies, which is much better than the prior art.

[0044] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
