Abstract

The invention relates to a cutting-off device, particularly relates to a servo fly-cutter cutting-off device for a bag making machine, and belongs to the technical field of bag making machines. The servo fly-cutter cutting-off device for the bag making machine comprises a left supporting wall plate and a right supporting wall plate, wherein two side plates are respectively arranged in middles of the inner sides of the left supporting wall plate and the right supporting wall plate; a fly-cutter pressing plate is connected between the two side plates through bolts; a cylinder is fixed in the middle of an upper fixing plate; the lower end of a piston rod of the cylinder is connected with the fly-cutter pressing plate; a driven synchronous wheel and a driving synchronous wheel are in transmission through a transmission synchronous belt; and a driving power wheel and a driven power wheel are in transmission through a driving synchronous belt. The servo fly-cutter cutting-off device for the bag making machine is simple, compact and reasonable in structure, rapid in action transmission and high in bag making speed; bags which are cut off are neat and do not have deckle edges; and the bag making quality is high.

Description

technical field [0001] The invention relates to a cutting device, in particular to a servo flying knife cutting 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, the cutting knife device of the bag making machine cuts in half at the top and bottom of the two cutting knives. When the length of the plastic bag is greater than 600mm, if the conventional cutter cutting device is used, the requirements for the mechanical transmission are very high, and the requirements for the machining accuracy of the parts are very high, especially the straightness of the cutter cannot meet the requirements. Contents of the invention [0004] The purpose of the present invention is to overcome the abov...
