Double-circle diaphragm automatic film feeding device

Abstract

The invention discloses a double-circle diaphragm automatic film feeding device, which comprises a flat base, a first vertical support rod, a second vertical support rod, and a third vertical supportrod. The first vertical support rod, the second vertical support rod, and the third vertical support rod are mounted with a film placing device, a slack adjusting device, and a film feeding device. The film placing device comprises a carrier plate mounted on the top of the first vertical support rod by a hinge. The top of the first vertical support rod is mounted with a film placing roller by a fixing rod, and a film splitting shaft is mounted on the side of the first vertical support rod by an extension platform. The film feeding device comprises two sets of horizontal substrate arranged in parallel on the third vertical support rod. A convey belt is sleeved at the horizontal substrates by rollers. A glue coating roller is mounted on the side of the third vertical support rod top by a horizontal cantilever. The double-circle diaphragm automatic film feeding device can integrate the film feeding, splitting, and conveying, and can adjust the pressing effect of the diaphragm fitly whilethe films are independently fed, so that the different process requirements can be satisfied.

Description

technical field [0001] The invention relates to the technical field of feeding devices, in particular to an automatic film feeding device for double-circle diaphragms. Background technique [0002] With the development of the production process, basically all products need to be packaged before proceeding to the next stage. Due to the characteristics of small size, low cost and convenient use, plastic flexible packaging is more and more widely used in various fields. widely. In the molding of plastic flexible packaging, it is first necessary to unroll and overlay the roll film material printed with packaging patterns. Since the plastic film is very thin, it is not easy to control the direction and position of its transmission. [0003] When conveying the packaging film, the film roll is placed on the unwinding mechanism. When the packaging film comes out of the unwinding mechanism, the traction film feeding mechanism transports the packaging film forward to the packaging fi...

Problems solved by technology

However, when the film roll on the unwinding mechanism runs from a large roll to a small roll, the momentum and inertia of the film roll on the unwinding mechanism change every time, which leads to unstable film feeding. Therefore, the packaging film cannot be accurately Positioning will affect the packaging quality of the product, especially for double films, it is more difficult to control its position, and for double films, it may even require different positions and tightness requirements for the same group of films
