A winding device for bopp film

Abstract

The invention provides a winding device for BOPP film, which belongs to the technical field of machinery. It solves the problems in the prior art that the film needs to be manually cut off after the winding is completed, which is time-consuming and labor-intensive. The winding device of the BOPP film includes a base and a bracket one arranged on the base. The bracket one includes two columns, a winding shaft is arranged between the two columns, a winding cylinder is arranged on the winding shaft, and one end of the winding shaft is arranged There is a power mechanism; the right side of the support one is provided with a support two, and the support two includes a fixed plate, and the fixed plate is provided with a clamping mechanism and a slitting blade, and the slitting blade is connected with a sliding mechanism that can drive it to slide horizontally; The right side of the frame is provided with a bracket three, and the bracket three includes two mounting plates, and a tensioning mechanism capable of tensioning the film is arranged between the two mounting plates. The present invention can realize the self-cutting of the film after winding through the clamping mechanism.

Description

technical field

[0001] The invention belongs to the technical field of machinery and relates to a winding device for BOPP film. Background technique

[0002] BOPP film is the abbreviation of "Biaxially Oriented Polypropylene", that is, biaxially oriented polypropylene film. Its production is to melt and extrude the raw material of high molecular polypropylene through an extruder to form a melt, and then make a sheet or a thick film through a long and narrow head, and then in a special stretching machine, at a certain temperature and setting Stretching on vertical longitudinal stretching machine and transverse stretching machine simultaneously or step by step at a certain speed, and after proper cooling, heat treatment or special processing, it is made into a film, and then it is made into a film by tensioning and winding. Semi-finished products are finally cut into finished products of appropriate width using a slicer.

Examples

Embodiment Construction

[0026] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0027] Such as Figure 1~3 As shown, a winding device for a BOPP film includes a rectangular base 1 on which a support 1, a support 2 and a support 3 are sequentially arranged from left to right.

[0028] Support one includes two upright columns 2 vertically fixed on the base 1, and a winding mechanism capable of winding up the film is arranged between the two upright columns 2 .

[0029] Such as figure 1 As shown, the winding mechanism includes a winding shaft 5 arranged between two uprights 2 , both ends of the winding shaft 5 are arranged on the two uprights 2 through bearings, so that the winding shaft 5 can rotate on the uprights 2 . Rewinding shaft 5 is detachably provided with winding drum 6, and the length of windi...
