Description

Plastic film winding device with automatic deviation correcting function Technical Field The utility model relates to the technical field of plastic films, in particular to a plastic film winding device with an automatic deviation correcting function. Background The plastic film is an indispensable material in modern industry, and is widely applied to the fields of food packaging, medicine, chemical industry, agriculture, building and the like, and in the production process, the film is required to be tidied and wound through a winding device so as to ensure the flatness and the integrity in the subsequent use. In the prior art, in the winding process, the film deviates from a preset track due to uneven tension and thickness difference, the film is finally wound irregularly, folds or looseness occur, the product quality is affected, films with different thicknesses or materials have different requirements on the tension, the film cannot keep uniform tension in the transmission process due to fixed guide roller spacing, the precision of the subsequent process is affected, and therefore the plastic film winding device with the automatic deviation correcting function is provided to solve the problem. Disclosure of utility model In order to solve the technical problems that in the prior art, films deviate from a preset track due to uneven tension and thickness difference in the rolling process, the films are wound unevenly, the requirements of films with different thicknesses or materials on the tension degree are different, and the films cannot keep uniform tension in the transmission process due to fixed guide roller spacing, the application provides a plastic film rolling device with an automatic deviation correcting function. The utility model provides a plastic film winding device with an automatic deviation correcting function, which comprises a frame, wherein a winding mechanism is arranged on the upper surface of the frame and comprises a winding roller, and the film is wound by the rotation of the winding roller. The upper surface of the frame is provided with an adjusting mechanism, the adjusting mechanism comprises two press rolls, and the lifting of one press roll is used for adjusting the relative distance between the press roll and the other press roll. Preferably, the winding mechanism further comprises a moving motor, the moving motor is fixedly arranged on the rear end surface of the frame, and an output shaft of the moving motor is rotatably connected with a rear end groove of the frame through a bearing.
