Automatic film-drawing tail cutting device for roll paper film-drawing packaging

Abstract

The invention discloses an automatic film-drawing tail cutting device for roll paper film-drawing packaging. The automatic film-drawing tail cutting device comprises a supporting bottom frame, a sheartype automatic clamping part, an automatic film-drawing tail cutting part and an automatic adhesive tape pasting part. The shear type automatic clamping part comprises a supporting seat, a fixed clamping plate, a swing clamping plate and a swing driving part. The automatic film-drawing tail cutting part comprises a lifting frame, a pushing vertical frame and an arc-shaped pressing plate. The automatic adhesive tape pasting part comprises a mounting vertical plate, a main pressing pasting roller, an adhesive tape guiding roller, an adhesive tape roll mounting seat, an auxiliary pressing pasting roller and an adhesive tape cutting blade, wherein the main pressing pasting roller, the adhesive tape guiding roller, the adhesive tape roll mounting seat, the auxiliary pressing pasting roller andthe adhesive tape cutting blade are mounted on the mounting vertical plate. According to the automatic film-drawing tail cutting device, on the premise that automatic film-drawing tail cutting and automatic adhesive tape pasting are effectively conducted on a packaging film of finished roll paper film-drawing packaging, the waste amount of the packaging film is greatly decreased, the utilizationrate of the packaging film is greatly increased, and the automatic film-drawing tail cutting device is especially suitable for a roll paper film-drawing packaging line for packaging finished roll paper produced by a paper machine.

Description

technical field [0001] The invention relates to an automatic film tail-cutting device, in particular to a film-drawing automatic tail-cutting device of a roll paper film packaging line for packaging roll paper products produced by a paper machine, and belongs to the technical field of packaging. Background technique [0002] Paper is generally composed of water suspensions of plant fibers that have been pulped, staggered on the net, dehydrated initially, and then compressed and dried. At present, papermaking is a continuous machine-made papermaking machine that includes raw material preparation, pulping, papermaking, and papermaking machinery until it is made into a roll paper or a finished sheet. [0003] Industrial roll paper is a paper roll made of paper made by a paper machine and cut by a rewinding machine. It meets the national standard or the width and diameter of the user's requirements. It can be used in various industries such as rotary printing and automatic packa...

Problems solved by technology

This manual operation method is not only inefficient, but also because the finished roll paper is usually larger in diameter and heavier in weight, so not only the labor intensity of the operator is high, but also there are risks such as crushing and pinching; in addition, because the finished roll paper Usually large in diameter, so manual roll packaging requires a long rolling path, which makes it impossible to pack in a tighter space

[0004] Although the stretch film packaging machine in the prior art can realize automatic winding packaging, the stretch film packaging machine can usually only perform automatic winding packaging of the diaphragm along the vertical axis as the surrounding axis, and the top and bottom surfaces of the packaged items cannot be automatically wound. Packaging, even if it is possible to lay a separate diaphragm on the top surface of the packaged items and then carry out automatic winding packaging, it is impossible to achieve the packaging of the bottom surface of the packaged items. Therefore, the stretch film packaging machine is usually suitable for multiple regular boxes that have been independently packaged. Whole stretch film packaging after being stacked on pallets

However, for single-rolled webs with heavy weight and large size, it is difficult to realize the automatic stretch film packaging of first laying the diaphragm on the two round ends and then automatically winding the diaphragm. Therefore, people in the paper industry usually do not consider the use of stretch film packaging. How to realize automatic and rapid packaging of heavy and large roll paper products, and realize automatic film-drawing and tail-cutting are still difficult problems in the industry.
