Abstract

The invention relates to an automatic conveying and trimming device for a plastic film roll. The device comprises clamping devices used for clamping a paper tube, a cutting device arranged above the clamping device, and a conveying device arranged between the clamping devices and used for conveying the film roll. The clamping devices comprise top shafts symmetrically arranged on the two sides of the conveying device and driving devices arranged behind the top shafts for driving the top shafts to advance or retreat; the positions of the top shafts correspond to the center of the paper tube, anddriven gears are arranged on the top shafts and driven by a transmission device to rotate. The paper tube is clamped by the clamping devices, the position of a blade is adjusted by a position adjusting device to achieve the cutting effect on the film roll, and the end face of the film roll is kept tidy. The top shafts can carry out self rotation while advancing or retreating, can drive the papertube to rotate together when clamping the paper tube, and are matched with a cutter to carry out proper position adjustment in the whole process, so that the automatic trimming work of the film roll is completed.

Description

technical field [0001] The invention relates to the field of film production equipment, in particular to a device for automatically conveying and trimming plastic film rolls. Background technique [0002] When the film is wound on the paper tube, due to the characteristics of the film itself, the two ends of the finished film roll are uneven. First, it affects the appearance of the product, and second, the film is easy to break during use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a device capable of trimming the end face of the plastic film roll to make the end face of the film roll neat and avoid the phenomenon of film breaking during use. [0004] The technical scheme adopted in the present invention is: an automatic conveying and trimming device for plastic film rolls, which includes a clamping device for clamping paper tubes, a cutting device arranged above the clamping device, and a cutting device arr...
