Packing film and rewinding device using packing film

Abstract

The invention discloses a packing film and a rewinding device. The packing film is provided with viscous areas and non-viscous areas alternately arranged; the adjacent viscous areas and non-viscous areas are connected through double-sided adhesive tape joints; and the viscous areas are provided with induction labels for braking packing equipment. The rewinding device comprises a base; the base isprovided with a left support column and a right support column; a left platform is arranged on the left support column; a right platform is arranged on the right support column; a slide base is arranged on the left platform; a left shaft sleeve capable of rotating around the center axis is mounted on the slide base; the base is provided with a first driving device for driving the slide base to move in the axial direction of the left shaft sleeve; the right platform is provided with a right shaft sleeve capable of rotating around the center axis and a second driving device for driving the rightshaft sleeve to rotate; and a rewinding roller is connected between the left shaft sleeve and the right shaft sleeve through a spline. The packing film can accurately brake the packing equipment, andcan quickly taken down the rewinding roller during producing of the packing film to greatly improve the production efficiency.

Description

technical field [0001] The invention belongs to the technical field of packaging material production, and in particular relates to a packaging film and a rewinding device used for the packaging film. Background technique [0002] Packing film is one of the commonly used packaging materials for agricultural harvesting operations. It is soft in texture and has a large single packaging volume, so it is suitable for on-site packaging of economic crops such as cotton. When packing, the baler uses the packing film to wrap the package, and then cuts the packing film, and finally sticks tape on the cutting place to complete the packing operation. [0003] When the packaging film is packaged, it is necessary to brake the packaging equipment at a specific moment. The current braking condition is based on the delivery time of the packaging film. However, due to the impression of many factors, the packaging film cannot stop within the specified time, so that the The double-sided adhesi...

Problems solved by technology

However, the problem in this process is that in order to facilitate the removal of the rewinding roller, the installation of the rewinding roller is often in a non-fixed manner, and its two ends are directly supported on the corresponding parts of the frame, which causes the rewinding roller It is not installed with bearings but in direct rolling contact with the frame bracket, which will cause long-term rolling friction between the rewinding 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
