Description

Technical Field

[0001] The invention relates to the field of food packaging, in particular to a double-sided film composite device for processing food packaging bags. Background Art

[0002] The double-sided film laminating device for food packaging bags is used to cover the double-sided film on the packaging paper substrate at the same time. Its core functions include gluing, laminating, tidying and drying and curing. The existing Chinese patent with publication number CN211917866U discloses a food packaging bag preforming device, which includes a discharging device, a tensioning device and a material guiding device in the order of packaging film transmission. The discharging device, the tensioning assembly and the material guiding device are all fixed between two parallel and opposite fixed plates. The tensioning device includes a matching fixed tensioning roller and a movable tensioning roller. The present invention protects the forming of a food packaging bag; however, the food packaging bag preforming device still has the following defects: 1. Traditional food packaging paper adopts the design of adding a single-sided film on the surface of the packaging paper. The function of the film is to prevent the food from getting damp and the oil in the food from precipitating and contaminating other items. The traditional film-applying method is relatively complicated, and the specific work process includes gluing, laminating, cleaning and drying and curing; 2. In addition, the shapes of foods are diverse. Traditional food packaging bag processing uses a single linear cutting method to cut the film during packaging, which can easily lead to excessive outer packaging methods and increase transportation costs. In addition, there is a situation where the film cannot fit the surface of different types of food, and only a single size of film can be cut. However, food needs to go through two packaging processes during processing: independent packaging and centralized packaging, and different types of food are also of different sizes.

[0013] The present invention provides a double-sided film composite device for food packaging bag processing by improvement, which has the following improvements and advantages compared with the prior art: Firstly, the main improvement of this device lies in the design of the automatic glue coating roller in the double-sided glue coating mechanism, which realizes double-sided synchronous glue coating and lamination through an S-shaped path, avoiding the defect that traditional single-sided lamination requires multiple operations: first, glue coating grooves are evenly set on the surface of the first glue coating roller, and an L-shaped transmission rod and a heating wire are arranged inside the scraper plate. When the film contacts the first glue coating roller, the first motor drives the transmission roller shaft to rotate while driving the film to move, and the transmission roller shaft drives the L-shaped transmission rod inside the straight rail slide to move along the trajectory where the curved rail slide and the straight rail slide overlap, so as to achieve the effect of expanding and contracting the scraper plate. The pressure of the first glue coating roller is adjusted by the overlapping limit of the L-shaped transmission rod and the straight rail slide and the curved rail slide, ensuring that the film and the substrate are closely attached; when the scraper plate is away from the glue coating groove, the glue flows out from the gap between the glue coating groove and the scraper plate, and is evenly smeared on the surface of the film through the scraper plate. In addition, the heating wire embedded in the scraper plate can prevent the glue from solidifying, improve the stability of glue coating, and improve the composite strength; In addition, the second film gluing structure has the same internal parts as the first film gluing structure. It is configured with upper and lower double rollers and uses symmetrically arranged rollers for gluing, which are divided into a first gluing roller and a second gluing roller. The base film passes between the two rollers in an S-shaped path to achieve double-sided synchronous gluing. In addition, the first gluing roller and the second gluing roller have opposite rotation directions and are independently controlled by dual motors to reduce the deviation caused by meshing transmission.

[0014] Secondly, by starting the processing table to move the movable slider, the food positioning fork is pushed toward the processing table, so that the food to be packaged can be fixed; then the third motor is started to drive the transmission disk to rotate, the transmission disk rotates through the transmission threaded rod, and the transmission threaded rod drives the movable slider to move through the threaded transmission, so as to adjust the eccentric distance of the movable slider on the transmission disk when the third motor rotates. The larger the distance, the larger the circular film cut. Then the second limiting rail is driven away from the film cutting knife at one end of the movable slider to cut the film. The first limiting rail and the second limiting rail have the function of limiting. Then the fifth motor is started to drive the film cutting knife to rotate, and the film cutting knife cuts the film. In addition, when the fifth motor is reversed, the elastic element pushes the hinged cone block to be stuck in the toothed ring inside the one-way inner toothed ring. At this time, the fifth motor can drive the circular cutting knife to cut the film of the same size as the circular cutting knife. The circular cutting knife can be replaced according to the size of the food. The function of the circular cutting knife is to facilitate cutting of small single circular food of independent packaging. The replaceable circular cutting knife and the movable slider that can adjust the size of the cutting circle can flexibly adapt to foods of different sizes and shapes.

In addition, when the fifth motor 809 reverses, the elastic element 813 pushes the hinged cone block 812 to get into the toothed ring inside the one-way inner toothed ring 811. At this time, the fifth motor 809 rotates to drive the circular cutting knife 814 to cut the film of the same size as the circular cutting knife 814. The circular cutting knife 814 can be replaced according to the size of the food. The function of the circular cutting knife 814 is to facilitate cutting of small single circular foods that are independently packaged.
