Technical Field

[0001] The utility model relates to the technical field of die cutting, in particular to a bender regulator for a protective film ear. Background Art

[0002] During the die cutting process of the protective film, it is necessary to fold the ear of the protective film onto the protective film. At present, the ear of the protective film needs to be folded manually by the operator, with slow efficiency and inaccurate folding. The folding quality of the ear of the protective film is greatly affected by the experience of the operator. There are phenomena such as deviation, dislocation, unevenness, and dirt on the folded ear of the protective film, resulting in frequent returns by customers. Content of the Utility Model

[0004] The technical solution adopted by the utility model is as follows:

[0005] The bender regulator for a protective film ear includes a bending part and a pressing part. The bending part is an arc-shaped plate with a semi-circular cross-section. The inner diameter of the bending part gradually decreases from the front end to the rear end of the bending part. The bending part is used for bending the ear of the protective film. The top edge of the bending part extends forward obliquely to form a flat structure. The pressing part is arranged at the rear end of the flat structure, and the pressing part is used for pressing the folded ear of the protective film to form a crease.

[0006] Preferably, the front end of the bending part has a slope structure, which is convenient for the ear of the protective film to be bent into the bending part.

[0007] Preferably, the front end of the bending part is provided with a mounting hole.

[0008] Preferably, the pressing part is a wedge-shaped structure, and the bottom of the wedge-shaped structure pressing part is wide and the top is narrow. The top of the wedge-shaped structure pressing part is connected to the rear end of the flat structure, so that a wider pressing surface is formed at the bottom of the pressing part.

[0009] Preferably, the bottom surface of the wedge-shaped structure pressing part is parallel to the top surface of the protective film. A pressing gap is formed between the bottom surface of the wedge-shaped structure pressing part and the top surface of the protective film, and the folded ear of the protective film passes through the pressing gap.

[0010] The beneficial effects of the utility model are as follows:

[0011] During the die-cutting of the protective film, it can achieve continuous and stable bending effects on the pull tabs of the protective film, reducing manual operation processes, improving production efficiency, product accuracy and flatness, ensuring the maintenance of product cleanliness, guaranteeing the quality of shipped goods, reducing manufacturing costs and the risk of rework and returns.

[0019] The following specifically introduces the present utility model in combination with the drawings and specific embodiments.

[0020] As Figures 1-4 shown, this embodiment is a pull-tab bending regulator for a protective film, including a bending part 1 and a pressing part 2. The bending part 1 is an arc-shaped plate with a semi-circular cross-section. The inner diameter of the bending part 1 gradually decreases from the front end to the rear end of the bending part 1. The bending part 1 is used to bend the pull tab 4 of the protective film 3. The top edge of the bending part 1 extends forward obliquely to form a flat structure 11. The pressing part 2 is arranged at the rear end of the flat structure 11. The pressing part 2 is used to press the bent pull tab 4 of the protective film 3 to form a crease.

[0021] In this embodiment, a slope structure 12 is arranged at the front end of the bending part 1; it is convenient for the pull tab 4 of the protective film 3 to bend into the bending part 1; at the same time, a mounting hole 13 is arranged at the front end of the bending part 1; the regulator in this embodiment is installed on the side in the advancing direction of the production line through the mounting hole 13.

[0022] In this embodiment, the pressing part 2 is a wedge-shaped body structure, and the bottom of the wedge-shaped body structure pressing part 2 is wide and the top is narrow. The top of the wedge-shaped body structure pressing part 2 is connected to the rear end of the planar structure 11; a relatively wide pressing surface is formed at the bottom of the pressing part 2; the bottom surface of the wedge-shaped body structure pressing part 2 is parallel to the top surface of the protective film 3, and a pressing gap is formed between the bottom surface of the wedge-shaped body structure pressing part 2 and the top surface of the protective film 3. The pulled ear 4 of the protective film 3 after bending passes through the pressing gap.

[0023] During the die-cutting of the protective film, this embodiment can achieve a continuous and stable bending effect on the pulled ear of the protective film, reduce the manual operation process, improve the production efficiency, product accuracy and flatness, ensure the maintenance of product cleanliness, guarantee the quality of shipped products, reduce the manufacturing cost and the risk of rework and return.
