The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

As shown in fig. 1 and 2, the punching apparatus of the present embodiment includes a frame 10, a punching mechanism 20, a tensioning mechanism 30, a first driving mechanism 40, and a second driving mechanism 50. Wherein the punching mechanism 20 is provided on the frame 10. The tension mechanism 30 is provided on the frame 10, and is disposed opposite to the punching mechanism 20. The first driving mechanism 40 is provided between the frame 10 and the punching mechanism 20, and the first driving mechanism 40 is adapted to drive the punching mechanism 20 to move in the horizontal direction. A second drive mechanism 50 is provided between the frame 10 and the tensioning mechanism 30, the second drive mechanism 50 being adapted to drive the tensioning mechanism 30 in a vertical direction.

With the technical solution of the present embodiment, during production, the film passes through the punching mechanism 20 and the tensioning mechanism 30 in sequence. The first driving mechanism 40 can adjust the position of the punching mechanism 20 in the horizontal direction, thereby adjusting the relative position between the punching mechanism 20 and the film in the direction perpendicular to the feeding direction. The second driving mechanism can adjust the position of the tensioning mechanism 30 in the vertical direction, and thus the relative positions of the punching mechanism 20 and the film in the feeding direction. Through the adjustment of the two positions, the punching mechanism 20 and any position of the film in the horizontal direction can be changed, so that punching at different positions of the film is realized, and the punching device can be compatible with punching requirements of films with different specifications. Therefore, the technical scheme of the embodiment overcomes the defect that the punching position of the punching device in the prior art is fixed, so that the production efficiency is low.

In the drawings, the broken lines are thin films, and in actual production, the thin films pass through the punching mechanism 20 and the tensioning mechanism 30 in this order from the left to the right direction as shown in fig. 1. And the film passes through the tension mechanism 30 after the punching mechanism 20 extends in an upward and obliquely upward direction. Within the length of a bag, the roller feeding the film stops rolling and the film material stops moving.

Further, the film web is provided with a damping to provide tension (not shown) in the feeding area to tension the film. When the second driving mechanism 50 drives the tensioning mechanism 30 to rise under the condition that the film stops moving, the film can be stretched forwards, and the hole punched by the punching mechanism 20 is farther away from the bag opening. When the second driving mechanism 50 drives the tensioning mechanism 30 to lower, the film can be retracted due to the pulling force, and the hole punched by the punching mechanism 20 is closer to the bag opening.

As shown in fig. 3 and 4, in the present embodiment, the first driving mechanism 40 is a driving cylinder, and a push rod of the driving cylinder is connected to the punching mechanism 20. Specifically, the arrangement direction of the driving cylinder is perpendicular to the feeding direction of the film, so that when the push rod of the driving cylinder extends or retracts, the punching mechanism 20 can be driven to move integrally in the left-right direction, and the relative position between the punching mechanism 20 and the film in the left-right direction can be adjusted.

Preferably, the driving cylinder may be a cylinder, a pneumatic cylinder, or the like.

Of course, the first driving mechanism 40 may be other conventional linear driving mechanisms, such as a lead screw and nut mechanism, a rack and pinion mechanism, and so on.

As shown in fig. 3 and 4, in the solution of the present embodiment, the punching mechanism 20 includes a mounting frame 21, a push rod of a driving cylinder is connected with the mounting frame 21, one of the frame 10 and the mounting frame 21 is provided with a slide rail 11, the other is provided with a slide block 211, and the slide rail 11 and the slide block 211 are matched.

Specifically, the mounting frame 21 in this embodiment is a flat plate structure and is used for mounting the punching related structure. The bottom of the mounting frame 21 is provided with a sliding block 211, the rack 10 is provided with a sliding rail 11, and the sliding block 211 is matched with the sliding rail 11, so that the mounting frame 21 can slide along the extending direction of the sliding rail 11.

Preferably, the extending direction of the slide rail 11 and the feeding direction of the film are arranged perpendicularly.

Of course, in some embodiments, not shown, the positions of the slide rail 11 and the slider 211 may be interchanged.

As shown in fig. 3, in the present embodiment, the punching mechanism 20 further includes a lower die 22, an upper die 23, and a third driving mechanism 24. Specifically, the lower die 22 is provided on the mount frame 21. The upper die 23 is provided on the mounting frame 21 above the lower die 22. A third drive mechanism 24 is provided between the mounting frame 21 and the upper die 23, and the third drive mechanism 24 drives the upper die 23 to move toward the lower die 22.

As can be seen from fig. 3, a gap is formed between the lower die 22 and the upper die 23. In actual production, the film passes through the gap between the lower die 22 and the upper die 23. After the punching position is adjusted, the third driving mechanism 24 drives the upper die 23 to move downwards, so that the upper die 23 and the lower die 22 are matched, and the punching operation is realized.

Further, the lower die 22, the upper die 23, and the third driving mechanism 24 are arranged in parallel to form a plurality of holes in the film at a time.

The elastic restoring member 233 is disposed inside the pressure plate 231.

At this time, the third driving mechanism 24 drives the upper die 23 to further descend, and the punch 232 penetrates through the film after passing through the punched hole 2311, so as to realize punching. And simultaneously, the punched waste film falls into a waste box below.

Further preferably, the front end of the pressing plate 231 is made of soft materials such as polyurethane, natural rubber, and silicone rubber, so as to enhance the friction force with the film after pressing.

It is further preferred that the lower end of the punch 232 is tapered so that the punch 232 penetrates the film more easily.

Specifically, the tension shaft 31 is arranged in the horizontal direction, and the film passes over the tension shaft 31. The tensioning shaft 31 is rotatably arranged to facilitate transport of the film. A part of the frame 10 forms a gate structure in which the tension shaft 31 is disposed, and the power output from the second driving mechanism 50 is converted into the up and down movement of the tension shaft 31 by the transmission mechanism 60.

Wherein, the rotating shaft 61 is arranged along the vertical direction, the rotating shaft 61 is provided with an external thread section, and the second driving mechanism 50 drives the rotating shaft 61 to rotate. The mounting block 62 is connected with the tensioning shaft 31, the mounting block 62 is provided with an internal threaded hole 621, and an external threaded section is arranged in the internal threaded hole 621 in a penetrating manner. Specifically, when the second driving mechanism 50 drives the rotating shaft 61 to rotate in different directions, the mounting block 62 is driven to ascend or descend, so as to drive the tensioning shaft 31 to ascend or descend. Further, the rotating shaft 61 is arranged on the outer side of the door-shaped structure, a through groove extending up and down is formed in the outer side edge of the door-shaped structure, and the tensioning shaft 31 penetrates out of the through groove and then is rotatably connected with the mounting block 62.

Of course, the transmission 60 may be other linear transmissions, such as a rack and pinion mechanism.

Preferably, the outer side of the door-shaped structure is further provided with a guide post, the guide post and the rotating shaft 61 are arranged in parallel, the mounting block 62 is provided with a through hole, and the guide post is arranged in the through hole in a penetrating manner.
