Abstract

The invention relates to a film pressing device, in particular to a film pressing device of a sack-making machine, and belongs to the technical field of sack-making machines. The film pressing device of the sack-making machine comprises an idler wheel shaft and an air cylinder, the idler wheel shaft is connected with a left swing arm support and a right swing arm support through bearings at the two ends of the idler wheel shaft, the air cylinder is connected with an air cylinder support through a pin roll, and the air cylinder support is fixed onto an air cylinder base. The front end of a piston rod of the air cylinder is connected with a knuckle bearing through threads, and the knuckle bearing is connected with the left swing arm support in a rotating mode. The film pressing device of the sack-making machine is simple, compact and reasonable in structure, stable in work, convenient to operate, good in use effect and low in cost.

Description

technical field [0001] The invention relates to a laminating device, in particular to a laminating device of a bag making machine, which belongs to the technical field of bag making machines. Background technique [0002] The bag making machine generally includes several processing devices, which are connected and driven by the driving mechanism, so as to realize the processing of plastic films into plastic bags. [0003] In the prior art, a cutter is needed to trim the bag when the edge of the bag has rounded corners. When trimming the bag, use the blower device to increase the suction waste box to automatically collect the waste, but the waste is easy to be stuck by the bag and cannot be completely absorbed by the waste box. Contents of the invention [0004] The purpose of the present invention is to overcome the above disadvantages, thereby providing a film pressing device for a bag making machine, which can press the film stably and reliably, is easy to use, and has ...
