Description

TECHNICAL FIELD

[0001] The utility model relates to the field of film processing technology, especially to a adjustable die -cutting equipment based on PET film processing. BACKGROUND

[0002] In the field of PET film processing, die-cutting equipment plays a key role. With the development of industry, the requirements for the die-cutting precision and size flexibility of PET film are increasing. Traditional die-cutting equipment can only cut fixed size and shape, which cannot meet the diversified market demand. When the product specification changes, the entire die-cutting mold needs to be replaced, which not only increases the cost but also wastes time and reduces production efficiency. Moreover, in some special application scenarios, small-batch and multi-specification die-cutting of PET film is required, which cannot be effectively handled by traditional equipment. These problems promote the research and development of adjustable die-cutting equipment to realize the precision and size adjustability of PET film die-cutting and adapt to different production needs.

[0003] Polyester film needs to be die-cut during production. The polyester film needs to be placed on the surface of the die-cutting machine during die-cutting. The bottom of the polyester film is limited by the limiting block. Most of the existing limiting blocks are fixedly connected and cannot be adjusted, so that the die-cutting machine can only die-cut polyester film with uniform specifications, reducing the practicality.

[0004] The existing patent (publication number: CN215825419U) is a adjustable die-cutting device for PET polyester film processing, which includes a die-cutting machine main body, a placement plate fixedly connected to the surface of the die-cutting machine main body, connection rivets arranged at the four corners of the surface of the placement plate, the placement plate fixedly connected to the die-cutting machine main body through the connection rivets, a transmission groove horizontally opened at the bottom end of the surface of the die-cutting machine main body, a double-threaded screw rod rotatably horizontally arranged inside the transmission groove, and a screw sleeve threadedly connected to the two ends of the surface of the double-threaded screw rod. This PET polyester film processing adjustable die-cutting device can move the sliding rail by moving the screw sleeve. When the sliding rail moves, the limiting block will move through the connecting block, so that the limiting block can be adjusted to the left and right positions on the surface of the die-cutting machine main body. The limiting block can be adjusted in position according to the size of the polyester film, improving the practicality.

[0005] To solve the above problems, the existing patent provides a solution. When die-cutting PET film, the required die-cutting mold cannot be adjusted in real time due to the lack of real-time adjustment structure, reducing the flexibility of die-cutting mold switching.

[0006] Therefore, an adjustable die-cutting equipment based on PET film processing is proposed. Utility model content
