Swing arm feeding device with damping mechanism

Abstract

The invention discloses a swinging arm type feeding device equipped with a damping mechanism. The swinging arm type feeding device is characterized in that a pair of rubber rolls are mounted on a support; the support is hinged with one end of each swinging arm by a driving shaft at the rear end of the support; grooves opened upwards are formed at the other ends of the swinging arms; the driving shaft is rotationally connected with the support, and is fixedly connected with the swinging arms; one end of the driving shaft is in transmission connection with a swinging arm driving motor mounted on the support by a gear transmission mechanism; rollers are mounted at the two ends of a raw material shaft respectively; the gear transmission mechanism comprises a driving gear and a driven gear; the driven gear is provided with a gearless part; the gearless part is rotated upwards, relative to the swinging arms, from an initial position, to a position where the gearless part inclines towards the rubber rolls; a central angle of the gearless part is greater than an included angle between the initial position of the gearless part and the position where the swinging arms are close to the rubber rolls; the damping mechanism and a swinging arm return driving mechanism are mounted on the driving shaft; and the damping mechanism and the swinging arm return drive mechanism can be mutually independent mechanisms. The swinging arm type feeding device has the benefits that the feeding is labor-saving; the energy consumption is low; and a structure is simplified.

Description

technical field [0001] The invention relates to a swing arm type feeding device equipped with a damping mechanism, which is used for feeding bag making machines (including plastic bag making machines). 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...
