Swing arm type feeding device

Abstract

The invention relates to a swing arm type feeding device which comprises a support, wherein a pair of rubber rollers is mounted on the support, and a rubber roller shaft of one rubber roller is connected with a rubber roller driving motor mounted on the support through a synchronous belt mechanism in a transmission manner. The swing arm type feeding device is characterized in that the rear end of the support is hinged with one end of a pair of swing arms through a driving shaft, and a groove with an upward opening is formed in the other end of the swing arms; the driving shaft is rotationally connected with the support and fixedly connected with the swing arms, and one end of the driving shaft is connected with a swing arm driving motor mounted on the support through a gear transmission mechanism in a transmission manner; a trolley wheel is respectively mounted at the two ends of a raw material shaft. The swing arm type feeding device has the beneficial effects that the labor is saved during charging, and the energy consumption is low; the structure is simple, and the manufacturing cost is reduced; through the longer groove and position switches arranged on the two sides of the groove, the swing arms can be controlled to gradually swing through an infrared sensor and limit switches on the swing arms, and the impact damage on the rubber rollers caused by overlarge swing amplitude is avoided.

Description

technical field [0001] The invention relates to a swing arm type feeding device, which is used for feeding a bag making machine, and 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 mechanism is...
