The left end in the first box body is provided with a first outer toothed plate. The inner center of the first outer toothed plate and the inner center of a second outer toothed plate are each provided with a first gear plate. The rear end center of the second gear plate is fixedly connected with a first connecting rod. A second connecting rod is arranged on the inner side of the first connecting rod. A first blocking plate is installed on the rear end outer surfaceof the second connecting rod. A fixed block is arranged between the first outer toothed plate and the second outer toothed plate. A supporting rod is fixedly connected with the lower end of the fixedblock. The guiding and covering device is convenient to detach, maintain and detect, has a preheating and sterilizing effect on the preservative film, and is high in automation degree and comprehensive and closed in film packaging, and preservative films with different lengths and sizes can be installed and placed without being easily wound and stuck.

Description

technical field [0001] The invention relates to the technical field of food packaging, in particular to a guiding and covering device for fresh-keeping film for food packaging. Background technique [0002] In food processing factories, many foods need to be packaged and processed before leaving the factory. Because some foods have a short shelf life, they need to be wrapped with a layer of plastic wrap to facilitate the increase of food transportation time. Therefore, a The covering device of plastic wrap will play a key factor in the production and sales of enterprises and manufacturers. Similarly, with the development of the economy, people's daily diet is becoming more and more abundant, which will easily lead to the problem of a large number of leftovers. , in order to save people usually put the leftovers into the refrigerator for storage, but in order to prevent the smell from passing through, it is often necessary to wrap it with plastic wrap. [0003] Most of the f...

Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of guiding and covering device for plastic wrap for food packaging, to solve the above-mentioned background technology that is inconvenient to disassemble and open for internal maintenance and inspection, and has no preheating and sterilizing effect on the plastic wrap, reducing the impact of the plastic wrap on Bacteria brought by food; only fixed-length plastic wrap can be installed, and only fixed-size food can be packaged, and it is inconvenient to switch quickly; there is no support shaft and discharge shaft, which makes the plastic wrap easily inside. Winding stuck; low degree of automation, no automatic film clamping, film ejection and cutting devices, and the problem that the food coating is not fully closed
