Description

Technical Field

[0001] The utility model relates to the technical field of film cutting devices, in particular to a pre-coated film cutting device. Background Art

[0002] Pre-coating refers to the process of pre-gluing and rewinding plastic film before laminating it with paper printed products. The pre-coating factory first applies glue on the film according to the specifications and format, then rewinds it for the user to choose, and then laminates it with the printed product. Laminating, also known as film pasting, is a processing technology that coats plastic film with adhesive, heats and presses it together with the paper printed product to form a paper-plastic integrated product. The printed product that has been laminated has a smoother and brighter surface because it has an extra layer of thin and transparent plastic film on the surface.

[0003] However, when the pre-coated film is cut, if the tension of the pre-coated film is insufficient, or the surface tension of the edges on both sides of the pre-coated film is uneven, it is easy to cause the film cut to be uneven and vertical, or to produce bending and wrinkles, forming cutting defects.

When the auxiliary tensioning member 9 contacts the surface of the pre-coated film, the pull rod 5, the driving bevel block 10 and the cutting blade 8 move further downward relative to the mounting plate 6, and the driving bevel block 10 squeezes the driven bevel block 93 to move outward, so that the auxiliary tensioning members 9 located on both sides of the cutting blade 8 generate a certain static friction pulling force away from the cutting blade 8, so that the pre-coated film in the area cut by the cutting blade 8 is in a relatively tight state, which is more conducive to the cutting blade 8 to cut the pre-coated film, and the cut edge of the pre-coated film is relatively smooth and not easy to bend or wrinkle.

[0024] Reference Figure 2 and Figure 3 As shown, the auxiliary tensioning member 9 in this embodiment includes a vertical rod 92 and a bending pressure rod 91, the vertical rod 92 is vertically connected to the bending pressure rod 91, and the driven inclined block 93 is arranged on the vertical rod 92; both ends of the mounting plate 6 are provided with a slide groove opening 61, and the top end of the vertical rod 92 is inserted into the slide groove opening 61 and is slidably connected thereto; specifically, the bending pressure rod 91 presses on the upper surface of the pre-coated film, and a return spring is abutted on the upper end of the vertical rod 92. When the driving inclined block 10 moves downward for cutting, the driving inclined block 10 pushes the driven inclined block 93 outward, and the vertical rod 92 squeezes the return spring; and when the cutting blade 8 moves upward after completion, the auxiliary tensioning member 9 can automatically return to its original position under the elastic force of the return spring.

[0025] Reference Figure 3 As shown, the bending angle of the bending pressure rod 91 in this embodiment is 60°-120°; specifically, during the movement of the bending pressure rod 91, the pre-coated film will be pulled toward the edge of the pre-coated film, thereby avoiding possible tiny wrinkles in the pre-coated film.

[0030] This embodiment also includes auxiliary rollers 12, which are respectively installed at both ends of the processing plate 1, and the auxiliary rollers 12 are arranged close to the traction assembly 7; they are mainly used in conjunction with the traction assembly 7, and when the pre-coated film is moving, the auxiliary rollers 12 play a rolling support role to reduce friction.
