A pull-back device used for packaging materials in the packaging process

Abstract

A pull-back device for a packaging material during packaging is disclosed, including packaging machines and extension boxes, a charging box is fixedly connected to the outer wall of the packaging machine, the inner bottom surface of the charging box is rotatably connected with a rotating upright post, the upper end of the charging box is overlapped with a sealing plate, and the top surface of thecharging box is fixedly connected with a positioning rod, the positioning rod is inserted into a positioning hole arranged on the surface of the sealing plate, the inside of the positioning rod is screwed with a locking screw, a finite position groove is arranged on the bottom surface of the sealing plate, a lower pressing ring is slidably connected with the inside of the limiting groove, and an elastic extruder is fixedly connected between the limiting groove and the lower pressing ring; A mating frame and an extension frame are arrange inside that packaging machine, the connecte frame and the extension frame are connected through telescopic rods, the spacing between the two is adjust according to the need, the mating frame and the extension frame provide a stretching channel for the film, the film is clamped by two clamping rollers, and the film is pulled back under the stretching of the telescopic rods.

Description

technical field [0001] The invention relates to the technical field of packaging devices, in particular to a pull-back device used for packaging materials during the packaging process. Background technique [0002] With the rapid development of the telemarketing industry, online stores drive the development of the logistics industry. The logistics industry uses plastic film wrapping for some packages with special requirements such as anti-seepage to prevent water infiltration and improve the firmness of the box. However, it is in The following disadvantages still exist in actual use: [0003] 1. The traditional way of handling the anti-seepage package is to turn and wrap the film manually, which is not only inefficient, but also requires a lot of labor. While the workers feel tired, the delivery time of the package is delayed; [0004] 2. Traditionally, the film is placed on the column to stretch and wrap the package, avoiding the inconvenience caused by wrapping the packag...

Problems solved by technology

[0005] 3. There is no pull-back device for the film when wrapping and wrapping, and there will be a lot of margin in the pulled out packaging film, which will make the tightness of the packaging material wrapped around the object loose, the overlapping degree of the packaging material will be uneven, and the packaging effect will be poor.
