Automatic folding device for packaging bag film

Abstract

The invention discloses an automatic folding device for a packaging bag film, and the automatic folding device is provided with a guide creasing roller mechanism, the guide creasing roller mechanism can automatically carry out creasing treatment on the film, subsequent folding is facilitated, the folding precision is improved, and the probability of deviation or folding deviation is reduced. The folding guide wheel mechanism is located between the pressing and folding mechanism and the guide creasing roller mechanism, by means of the folding guide wheel mechanism, a thin film can be folded step by step, the folding effect is improved, the phenomenon that the thin film deviates due to the fact that the angle is too large during folding is prevented, and folding fluency and smoothness are improved; the large folding wheel and the small guide wheel are used for guiding the indentation, meanwhile, the folding precision is further improved, the fold at the folding position is enhanced, and the large folding wheel and the small guide wheel are matched with the folding guide frame to convey the folded film to the folded film pressing and conveying mechanism so that the folded film pressing and conveying mechanism can completely fold and convey the film conveniently. The reliability and stability of folding conveying are improved, and the folding precision is guaranteed.

Description

technical field [0001] The invention specifically relates to an automatic folding device for packaging bag films, and relates to the technical field of auxiliary equipment for packaging bag preparation. Background technique [0002] At present, in the production process of the packaging film bag, it is generally necessary to fold the film first, and then use a sealing device or a hot embossing device to perform pressure sealing. Therefore, the effect and rate of film folding are related to the production efficiency and quality of film packaging bags. The most likely problem when the film is folded is the problem of deviation. Once it is deviated, it will lead to the need to stop debugging and re-fold the operation. Even if it deviates a little, it will cause quality problems in subsequent imprinting, etc. Therefore, the current folding device only relies on the folding guide frame to guide and fold, resulting in low folding efficiency, and it is difficult to effectively rea...
