Separated roll-up device for plastic bags

Abstract

The invention discloses a separated roll-up device for plastic bags, which mainly consists of a frame, a four-position rotary table device, a roll-up driving device, a roll-up conversion device, an ejector roller device and a partial position rotary table mechanism. In the rolling process, the roll-up conversion device drives a rack by a rack driving cylinder and a gear drives an overturning cover to overturn. The number of the rolled bags can be controlled simply by setting overturning moment of the overturning cover. The number of the rolled bags is simple and convenient to control. In the whole rolling process, the flexibility is high. The overturning structure principle is simple. The separated roll-up device is easy to manufacture. Moreover, the ejector roller device of the separatedroll-up device adopts an ejector roller cylinder as a power source, so that the situation that due to an excessively high pressure of the ejector roller, the whole roll of bags are excessively compact and are difficult to discharge or cannot be discharged after the bags are rolled up can be avoided. Due to the four-position rotary table device, a roll-up machine is ensured to work continuously inthe whole rolling process, so that a great amount of time is saved and the production efficiency is improved.

Description

technical field [0001] The invention relates to a plastic bag production equipment, in particular to a plastic bag splitting and rolling device. Background technique [0002] As daily necessities, plastic bags are widely used by people, such as shopping bags in supermarkets, garbage bags, fresh-keeping bags, etc. These plastic bags are rolled together continuously, and when people want to use them, they will be torn along the broken line by themselves. . There are two ways to roll the bag, one is continuous winding, and the other is sheet winding. With regard to sheet winding, in the actual production process, there will not be only one bag per roll. In order to achieve separate winding and continuous winding of multiple bags during the winding process, a process of separating and winding the finished bags is required in the production process, and at the same time, in order to ensure the continuity of production Therefore, the industry needs to develop a continuous sheet...

Problems solved by technology

[0003] For the sheet-to-sheet rewinding device, there will be a problem during the bag collection process. When the rewinding is blocked by the cover and the rewinding shaft completes the rewinding, when the next rewinding needs to be performed, the current rewinding needs to be terminated first. If If the position of the reel does not change, it will be difficult to complete this action

The method that can be taken is to suspend and stop the winding, unload the material, remove the finished product that has been rolled, and then resume the winding. In this way, the winding device of the winding machine is required to stop and start continuously, which consumes a lot of energy. time, low productivity
