An adaptive rewinding device

Abstract

The invention discloses a self-adaptive rewinding device, which comprises a main frame, and the main frame is also provided with a sub-frame and a film rolling roller driven by a driving device 2 to rotate around its own axis, and the sub-frame is provided with at least one The swing arm swings within a certain range and the reset device that makes the swing arm have a reset tendency. The swing arm is equipped with a detector and a pressure wheel to detect its swing angle. The arm rotates around its axis of rotation, and the detector acquires corresponding angle data; the driving device 2 outputs corresponding torque according to the angle data. The beneficial effect of the invention is that the rewinding speed can be automatically changed according to the thickness change of the roll film to improve the roll quality, and on this basis, the roll film roll can be quickly disassembled to improve the rewinding efficiency.

Description

Technical field[0001]The invention belongs to the technical field of packaging material production, and specifically relates to an adaptive rewinding device.Background technique[0002]Packing roll film is one of the commonly used packing materials for agricultural harvesting operations. It has a soft texture and a large single packing volume, so it is suitable for on-site packing of cotton and other economic crops. The roll film is usually a plastic film, and its manufacturing process is often blown and stretched. In the final stage of production, the film is usually wound on a paper tube to facilitate overall packaging and transportation.[0003]Due to the soft texture of the rolled film, uneven thickness changes due to too fast or too slow speed may occur during rewinding, and ultimately the quality of the film rolled into a roll is low. In addition, after the film winding is completed, the entire film roll must be removed from the rewinding equipment, and then the paper roll and fil...

Problems solved by technology

However, the problem with this process is that in order to facilitate the removal of the film roll, the film roll is often installed in a non-fixed manner, and its two ends are directly supported on the corresponding parts of the frame, which causes the film roll It is installed in direct rolling contact with the frame bracket without using bearings, which will cause long-term rolling friction between the roll film roller and the frame and aggravate the loss of parts. If the bearing is installed, it will increase the difficulty of later disassembly, and also Accuracy will be affected by repeated disassembly and assembly
