[0020] like Figures 1 to 7 As shown, a packaging bag side film cutting anti-winding press piece includes a main body fastening connecting plate 1, the upper end of the main body fastening connecting plate 1 is a horizontal plane, and the upper end position is matched with the conveying plane of the packaging bag conveying device when in use. The lower end of the main body fastening connecting plate 1 is an arc-shaped structure with an opening downward, which is fixed by it, so that the space of the lower end fastening position can be guaranteed to be larger and the air flow can be better. The right side of the main body fastening connecting plate 1 is provided with an integrally formed arc-shaped side edge pressing fitting plate 2, which can guide the side edge waste after cutting in a press-type manner to ensure reliable pressing force when collecting waste. The lower end arc-shaped structure of the main body fastening connecting plate 1 and the lower end arc-shaped surface of the side edge pressing fitting plate 2 are on the same diameter arc surface, so that the lower end of the overall structure is more flat. The thickness of the left side structure of the main body fastening connecting plate 1 is less than that of the right side structure, and the lower end of the main body fastening connecting plate 1 is provided with an integrally formed mounting support isolation boss 3 to ensure better strength of the fastening position and a safe isolation space. The lower end of the mounting support isolation boss 3 is a horizontal mounting reference mating surface, which makes the flatness better during fastening. The upper end of the main body fastening connection plate 1 is provided with two cylindrical integral fastening connection holes 4 distributed front and back, and the integral fastening connection holes 4 are located in the front and back direction of the mounting support isolation boss 3. The front end of the main body fastening connection plate 1 is a conical structure, which can be inserted into the matching structure of the installation position as needed, so that the overall matching strength is better. During use, it can perform compression fit at the positions before and after cutting, and can ensure that no tension is generated on the packaging bag body at the cutting position during the cutting process, effectively avoiding the situation in which the packaging bag is easily damaged during cutting and affecting the quality of the packaging bag product, and can ensure that the waste material after cutting can be safely separated from the packaging bag body, and can provide a downward guide when collecting the cut waste material, avoiding the situation in which entanglement is easy to occur during collection, making the overall processing smoother. The pressing part is more convenient to install, and its installation position is equipped with an isolation boss, which not only ensures a larger space for fitting, but also the lower end fastening position has a reliable ventilation space, and the packaging bag product is safer during cutting processing. When in use, first fix a pressing piece on the packaging bag conveying device, and the upper end of the main body fastening connecting plate 1 is used for the main structure of the packaging bag to fit through. The upper end of the packaging bag is then matched with a group of pressing pieces to clamp and limit the position of the packaging bag. The side clamping fitting plate 2 on the lower pressing piece structure can guide the cut waste to be collected from the lower position, ensuring that they are completely isolated.

[0021] Preferably, the width of the left side of the main body fastening connecting plate 1 is greater than that of the right side, so that the space at the left fastening position is larger and the matching area for pressing the packaging bag body is larger.

[0022] Preferably, the front-to-rear direction and the right end face of the side press-fit plate 2 are arc-shaped structural surfaces, which have a reliable avoidance effect when in use, while avoiding the existence of sharp-angle structures, and are safer when in use.

[0023] Preferably, the front and rear sides of the mounting support isolation boss 3 are respectively provided with stable arc grooves for avoiding positioning, so that this position can be closely associated with the structure of the fastening position when fastening, so that the overall fastening is better.

[0024] Preferably, installation avoidance fitting grooves are formed in the front and rear directions of the connection positions of the main body fastening connecting plate 1 and the side clamping fitting plate 2, respectively, to ensure that there is more space at the front and rear connection positions during fitting and better fitting safety.

[0025] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements or substitutions can be made without departing from the principles of the present invention. These improvements or substitutions should also be regarded as the protection scope of the present invention.
