Specific implementation manner

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 - 5 , in the embodiment of the present invention, a balloon film cutting device with an automatic trimming function includes a workbench 10 and at least one trimming mechanism 20 provided on the workbench 10. An feeding roller 11 and a discharging roller 12 are arranged on the workbench 10 along the film feeding direction. Specifically, in this embodiment, the feeding roller 11 is rotatably installed on the right side of the workbench 10, and the discharging roller 12 is rotatably installed on the left side of the workbench 10. The feeding roller 11 is used to convey the cut film sheet to the workbench 10. After the film sheet is trimmed on the workbench 10, the discharging roller 12 conveys the film sheet out of the workbench 10. The trimming mechanism 20 is arranged at the side of the workbench 10. That is, this embodiment is mainly applied to trimming the side of the film sheet. The trimming mechanism includes a base 21 and a blade 25. The base 21 includes a base frame 211 and a bending seat 212 installed on the base frame 211. The blade 25 is installed on the bending seat 212. Both the bending seat 212 and the blade 25 are flexible structures. That is, the bending seat 212 and the blade 25 will undergo bending deformation when stressed. A screw sleeve 27 is fixedly installed on the bending seat 212. The outer side of the screw sleeve 27 is threadedly connected with a screw rod 28. The screw rod 28 is rotatably connected with the base frame 211. When the screw rod 28 rotates, the screw rod 28 drives the screw sleeve 27 to move, so that the screw sleeve 27 pulls the bending seat 212, and the bending seat 212 and the blade 25 bend. It can be understood that when the blade 25 bends, the shape of the film will be changed when trimming the film with the blade 25. By adjusting the bending amount of the blade 25 through the screw sleeve 27, the shape of the film is changed, so that the trimmed film is suitable for balloon bag making of different specifications.

[0021] In the embodiment of the present application, a guide rod 22 is fixedly installed on the workbench 10, the side of the base 21 is slidably connected to the guide rod 22, and the bottom of the side of the base 21 is connected to the workbench 10 through a first spring 221 sleeved on the guide rod 22; the trimming mechanism also includes a pressing plate 23 and a top plate 24, the top plate 24 is fixedly installed on the upper end of the guide rod 22, the pressing plate 23 is arranged between the base 21 and the top plate 24, and a cylinder 26 is installed on the top plate 24, the telescopic end of the cylinder 26 is connected to the pressing plate 23, and the telescopic end of the cylinder 26 is extended to drive the pressing plate 23 to press down the base 21 and the blade 25, so that the blade 25 trims the film; further, in the embodiment of the present application, the blade 2 The bending seat 212 is slidably mounted on the bending seat 212. A sliding groove is provided on the inner side of the bending seat 212. A slider 213 is slidably mounted inside the sliding groove. The slider 213 is connected to the blade 25, and the slider 213 is connected to one side of the sliding groove through a return spring 214. The height of the pressing plate 23 is higher than that of the blade 25, and the pressing plate 23 is connected to the base frame 211 through at least one second spring 231. When the pressing plate 23 is pressed down, the pressing plate 23 first drives the base frame 211 to be pressed down through the second spring 231, so that the base frame 211 presses down the film on the workbench 10, thereby fixing the film. Then, the pressing plate 23 presses down the blade 25, and the fixed film is trimmed by the blade 25, thereby improving the trimming accuracy of the film.

[0022] In addition, in the embodiment of the present application, a gear box 29 and a drive motor 30 are fixedly installed on the workbench 10, and the output end of the drive motor 30 is fixedly connected to a drive shaft 31, and the drive shaft 31 is transmission-connected to the screw 28 through the gear box 29.
