[0038] Working principle: when the food packaging bag needs to be cut, the operator steps on the telescopic pedal 81, and the telescopic pedal 81 rotates around the connecting point between the telescopic pedal 81 and the processing table 1. Since the telescopic pedal 81 is telescopic, the bottom end of the telescopic pedal 81 pushes the hinged sliding seat 82 to rise during rotation. The rising of the sliding seat 82 drives the tension rod 83 to slide upward on the inner wall of the top end of the processing table 1. When the tension rod 83 rises, the guide rods 84 on both sides of the tension rod 83 also rise. The guide rods 84 slide in the guide grooves in the side walls of the guide plates 85, pushing the guide plates 85 to move transversely. Since the two sides of the cutting knife 4 slide in the inclined grooves of the guide plates 85 and the cutting knife 4 can only move straight up and down under the limitation of the guide grooves of the fixed frame 3, the transverse movement of the guide plates 85 will make the cutting knife 4 straightly descend in the fixed frame 3 and cut the food packaging bag. In this process, the tension rod 83 exerts tension on the cutting position of the food packaging bag to avoid loose cutting and prevent uneven or damaged packaging bag. When the cutting operation is completed, the operator releases the telescopic pedal 81, and the sliding seat 82 is reset under the elastic action of the limiting spring 87. One end of the limiting spring 87 is connected to the sliding rod 86, and the other end is connected to the fixed rod 88. When the sliding seat 82 drives the sliding rod 86 to descend, the limiting spring 87 returns to its original state, so that the whole tension cutting assembly 8 returns to the initial state.

[0039] When the winding roller 7 is installed, the position of the positioning rod 63 in the inner wall of the right support frame 5 is adjusted according to the length of the winding roller 7, the positioning rod 63 is inserted into the through hole on the right side of the winding roller 7, and in the insertion process, the clamping groove of the positioning rod 63 extrudes the wedge block 61, and the wedge block 61 can slide on the inner wall of the top end of the right support frame 5 under the action of the return spring 62, when the positioning rod 63 is inserted into the appropriate position, the wedge block 61 is clamped into the corresponding clamping groove of the positioning rod 63 under the elastic action of the return spring 62, so as to fix the positioning rod 63, thereby realizing the support and fixation of the installation position of the winding roller 7 with different lengths, when the cut food packaging bag needs to be wound, the motor 9 is started, the motor 9 drives the limiting rod 10 to rotate, since the limiting rod 10 is inserted into the limiting groove on the left side of the winding roller 7, therefore, when the limiting rod 10 rotates, the winding roller 7 will be driven to rotate synchronously, and with the rotation of the winding roller 7, the cut packaging bag conveyed by the conveying wheel 2 is gradually wound onto the winding roller 7.

[0040] Finally, it should be noted that: the above only for the preferred embodiments of the utility model, and does not limit the utility model, although the utility model is described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features, any modification, equivalent replacement, improvement etc. that is made within the spirit and principles of the utility model, should be contained in the protection scope of the utility model.
