Feeding device with swing arms and guide rails matched and for bag making machine

Abstract

A feeding device with swing arms and guide rails matched and for a bag making machine comprises a support. A pair of rubber rolls is arranged on the support, wherein a rubber roll shaft of one rubber roll is in transmission connection with a rubber roll driving motor installed on the support through a synchronous belt mechanism. The feeding device is characterized in that the rear end of the support is hinged to one ends of the pair of swing arms through a driving shaft, and the other end of each swing arm is provided with a groove with an upward opening; the guide rails inclining upwards and backwards are arranged on the back of the upper portion of the support, and the heights of the rear ends of the guide rails correspond to those of the grooves in the swing arms; the driving shaft is rotatably connected with the support and fixedly connected with the swing arms, and one end of the driving shaft is in transmission connection with a swing arm driving motor installed on the support through a gear transmission mechanism; two rolling wheels matched with the grooves in the swing arms and the guide rails are arranged on a raw material shaft. The feeding device has the beneficial effects that labor is saved during material loading, energy consumption is low, energy is saved, production cost is reduced, and the structure is simplified.

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 mecha...
