Film supply device

Abstract

The invention provides a film supply device used for providing a film belt with one face being a glued adhesive face for a film pasting device. The film supply device comprises a vertical plate (19). The vertical plate (19) is provided with an edged barrel (20) used for installing and rolling a film belt (3), and a wheel set tension mechanism used for enabling the film belt (3) to be wound and forming tension. The wheel set tension mechanism comprises three edgeless upper wheels (22) and two edged lower wheels (23), all of which are used for winding of the film belt (3). A vertical guide rail (24) and a sliding block (25) capable of vertically sliding along the vertical guide rail (24) are arranged below the upper wheel (22) arranged in the middle position. The two lower wheels (23) are symmetrically arranged on the sliding block (25) and located on the left side and the right side of the sliding block (25). The film supply mechanism further comprises a sixth wheel (26) for guiding the film belt (3) to the film pasting device, and a film clamping device (27). The film supply device is high in automation degree and operation efficiency, and the consistency of the supplied film belt is good.

Description

technical field [0001] The invention relates to a film supply device, in particular to a film supply device for supplying a film tape with one side of glue-coated sticky surface to a film sticking device according to the set requirements. Background technique [0002] Workpieces with a bright surface, such as a car with a variety of decorative strips, referred to as decorative strips. At present, metal bright strips are mostly used in mid-to-high-end cars, and the common ones are mainly aluminum strips and stainless steel bright strips, and the exposed surfaces are bright surfaces; In order to prevent the shiny surface from being damaged, a protective film, referred to as film, needs to be pasted on the shiny surface between each process in the processing process and before the finished product leaves the factory. The traditional film sticking method is to stick the film by hand. At present, some manufacturers develop special tooling for the film sticking operation, which re...

AI Technical Summary

Problems solved by technology

Practical tests have shown that a film tape with an adhesive side on one side is easily deflected when passing the rollers, resulting in edge curling

If the rollers all use edgeless rollers, when the glued adhesive surface of the film tape is in contact with the endless rollers, the stickiness will cause the offset to accumulate, which will cause the edge of the film tape to deviate from the edge of the endless rollers and curl; Side rollers, when the adhesive surface of the film tape is in contact with the side rollers, the offset will also accumulate due to the stickiness, causing the film strips to shift and stick to the side of the side rollers, which will also cause curling
