Problems solved by technology

However, in the process of tearing off the roll bag along the separation line, two hands are required to cooperate. One hand needs to fix the roll bag wound on the reel, and the other hand needs to pull the roll bag to be torn off. It's inconvenient
Especially when you have items in your hands, it is difficult to coordinate your hands to tear off the rolling bag
[0003] In addition, there is currently no operating device on the market that can tear off the rolling bag with one hand

Abstract

The invention discloses a rolling-bag tearing device which is composed of guide rail shell, a shaft, a pull rod, two clamping blocks, a plurality of slide rods, bearings, gears and two circular connecting plates with an aim to tear a rolling bag rapidly with a single hand and replace a rolled rolling bag rapidly. Two ends of the shaft are rotatably connected to the guide rail shell through the bearings, the circular connecting plates are fixedly connected to the middle of the shaft, and two ends of the shaft are fixedly connected with the gears; two ends of the pull rod are slidably connected onto the guide rail shell, the slide rods are connected between the pull rod and the guide rail shell, one ends of the slide rods are fixed on the guide rail shell, and the other ends of the slide rods are slidably connected on the pull rod; the clamping blocks are fixedly connected to two ends of the pull rod and are located right under the gears.

Description

technical field [0001] The invention relates to a device for separating continuous-roll bags, more specifically, a hand-tearing device for continuous-roll bags. Background technique [0002] Supermarkets usually use film bags to pack loose goods such as fresh food and vegetables, and then weigh them. These film bags are usually rolled end to end into a reel, so they are also called continuous roll bags. When in use, a film bag is pulled out from the reel and torn off along the dividing line, and then the mouth of the bag is twisted with fingers to put the items in. However, in the process of tearing off the roll bag along the separation line, two hands are required to cooperate. One hand needs to fix the roll bag wound on the reel, and the other hand needs to pull the roll bag to be torn off. It is more inconvenient. Especially when there are items in the hands, it is difficult to coordinate and cooperate with both hands to tear off the rolling bag. [0003] In addition, ...
