Description

Technical Field

[0002] Plastic film is mainly used for packaging and as a coating layer. It is widely used in the field of food packaging. People's demand for plastic film is increasing day by day, and the production volume of plastic film is also increasing. In the process of plastic film production, the finished plastic film needs to be rolled into a cylindrical shape for easy packaging and transportation.

[0003] Patent application number: CN202022206013.8 discloses a plastic film winding device, which discloses a base plate, and the four corners of the lower surface of the base plate are fixedly connected to the four groups of support seats, and the front and rear sides of the upper surface of the base plate are fixedly connected to the bottoms of the two groups of support plates, respectively.

The mounting plate is pushed by the spring to squeeze the winding roller on the surface of the friction roller. The friction roller is driven to rotate by the winding motor, and the friction force between the winding roller and the friction roller drives the winding roller to rotate rapidly. After the formed plastic film passes through the two conveying rollers, the plastic film reaches between the winding roller and the friction roller, and the plastic film is evenly wound on the winding roller. When a certain amount of plastic film is wound on the winding roller, the limit cylinder is started, and the piston rod on the limit cylinder is shortened, and a blank winding roller is placed on the winding device on the other side of the friction roller. After the blank winding roller reaches below the conveying roller, the cutting cylinder is started, and the piston rod on the cutting cylinder is extended. The cutter moves, and after the cutter cooperates with the knife holder to cut the plastic film, the cutting cylinder is started again, the piston rod on the cutting cylinder is shortened, and the cutter returns to the initial position. The cut plastic film is completely rolled up on the winding roller with the plastic film rolled up, and the plastic film between the conveying rollers moves again, and the starting end of the plastic film reaches between the blank winding roller and the friction roller, and the plastic film is rolled up by the blank winding roller again, and the winding roller with the rolled plastic film is removed, and the cycle operation is carried out, by placing blank winding rollers on both sides of the friction roller in turn, and after the winding roller on one side of the friction roller has rolled up a certain amount of plastic film, the blank winding roller placed on the other side of the friction roller continues to roll up the plastic film, so as to realize the continuous rolling of the plastic film, and there is no need to stop the machine to replace the blank winding roller, which greatly improves the production efficiency of the plastic film.

[0008] Preferably, a support rod is fixed to the mounting plate, the support rod passes through the limit block and is slidably connected to the limit block, and the support rod passes through a spring at a corresponding position.

[0009] Preferably, a lifting cylinder is fixed on the slide plate on one side of the limit block, and a lifting block is fixed at the end of the piston rod of the lifting cylinder. After the winding roller has wound up a certain amount of plastic film, both ends of the winding roller reach the position of the lifting block, the lifting cylinder is started, the piston rod on the lifting cylinder is extended, the lifting block moves, and the lifting block contacts the two ends of the winding roller and lifts the winding roller from the installation groove, so as to facilitate the collection of the winding roller.

[0010] Preferably, a plurality of guide plates are fixed on the bottom plates on both sides of the slide plate. The upper end of the lifting block is an inclined structure, and after the two ends of the winding roller are separated from the mounting groove, the winding roller automatically rolls down to the guide plate and is discharged and collected through the guide plate.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] By placing blank winding rollers on both sides of the friction roller in sequence, after the winding roller on one side of the friction roller has wound up a certain amount of plastic film, the blank winding roller placed on the other side of the friction roller continues to wind up the plastic film, thereby achieving continuous winding of the plastic film without stopping the machine to replace the blank winding roller, which greatly improves the production efficiency of the plastic film.
