The invention discloses a film feeding and cutting device of a film wrapping machine, which comprises a film cutting mechanism and a film feeding mechanism. The film is transported and cut in the film cutting mechanism, and the film feeding mechanism sends out the cut film. The film feeding and cutting device of this film packing machine is completed by dividing the film cutting and film feeding into two parts. The stability of the equipment is good, and it is not easy to block the film, which greatly improves the overall speed of the film packing machine and improves the production efficiency of the whole machine; By setting a vacuum system on the film feeding mechanism to absorb and fix the cut film, avoiding the occurrence of film forming wrinkles and ensuring the quality of the finished product.
Description
technical field [0001] The invention relates to the field of packaging machinery, in particular to a film feeding and cutting device of a film wrapping machine. Background technique [0002] The film cutting and feeding device of the traditional film charter mainly includes two pairs of film feeding rollers and a film cutting knife. The transmission of the two pairs of film feeding rollers is driven by a timing belt through a servo motor. The film cutting knife is driven by Driven by another servo motor, the film is sent up by the rotation of the film roller from the lower part, and then the film is tightened by the speed difference between the front and rear film rollers, and then the servo motor drives the film cutter to rotate quickly to cut the film, and then the front pair The film roller sends out the cut film. The distance between the centers of the two pairs of film rollers is about 500mm. The two actions of film cutting and film feeding must be completed quickly wit...
