Embodiment Construction

[0015] The present invention will be further described below in conjunction with the embodiments in the drawings:

[0016] Such as Figure 1~3 As shown, the present invention mainly includes a left supporting wall panel 1 and a right supporting wall panel 2, the upper ends of the left supporting wall panel 1 and the right supporting wall panel 2 are jointly connected to the upper fixing plate 4, and the lower ends of the left supporting wall panel 1 and the right supporting wall panel 2 Connect the lower fixing plate 5 together. A linear slide rail 24 is provided on the lower fixing plate 5.

[0017] The left support wall panel 1 and the right support wall panel 2 are respectively provided with a side panel 3 in the inner middle part, and the two side panels 3 are connected to the flying knife pressing plate 7 by bolts. The lower end of the flying knife pressing plate 7 is provided with a guide groove 7.1 to prevent the flying knife from tilting or bending during the sliding proc...

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, belonging to the technical field of bag making machines. Background technique [0002] The bag making machine generally includes several processing devices, which are connected to drive multiple processing devices through a driving mechanism, so as to realize the processing of plastic films into plastic bags. [0003] In the prior art, the cutting device of the bag-making machine is that the upper and lower cutting knives cut at the tips of the two cutting knives for cutting. When the length of the plastic bag is greater than 600mm, if the conventional cutter cutting device is used, the mechanical transmission requirements are very high, and the parts processing accuracy are very high, especially the straightness requirements of the cutter cannot meet the requirements. Summary of the invention [0004] The purpose of the present invention i...
