The feeding device of the bag making machine with the swing arm and the guide rail

Abstract

A feeding device for a bag making machine with a swing arm and a guide rail, including a bracket, on which a pair of rubber rollers are installed, and the rubber roller shaft of one of the rubber rollers is connected with the rubber roller driving motor installed on the bracket through a synchronous belt mechanism The transmission connection is characterized in that the rear end of the bracket is hinged to one end of a pair of swing arms through a drive shaft, and the other end of the swing arm is provided with a groove with an opening facing upward; There is a guide rail inclined upwards and backwards, the height of the rear end of the guide rail corresponds to the groove on the swing arm; the drive shaft is connected to the bracket in rotation and fixedly connected to the swing arm, and one end of the drive shaft is connected to the installation through the gear transmission mechanism. The drive motor of the swing arm on the bracket is connected by transmission; two rollers matched with the grooves on the swing arm and the guide rail are arranged on the raw material shaft. The beneficial effects of the invention are: labor saving for loading materials, low energy consumption, saving energy and production costs, and simplifying the structure.

Description

technical field [0001] The invention relates to a feeding device of a bag making machine in which a swing arm cooperates with a guide rail. The bag making machine includes a plastic bag making machine. Background technique [0002] The raw material of the bag making machine for making plastic bags is a cylindrical film (or sheet) rolled on a tubular shaft. When in use, the rolled raw material is lifted and placed on the bracket at the rear of the bag making machine. The disadvantage of this feeding method is that it is very laborious to manually install the raw materials. If the machine is used, it will not only take up space, but also increase the cost; because the bag making machine does not feed at a constant speed, it has to stop at equal intervals, so in order to avoid the raw material coils in the feeding In the process, the plastic film is curled and overlapped, and the raw material film needs to pass through multiple rollers alternately, and a free deflection mechani...
