Problems solved by technology

[0002] When the bag making machine is slitting, it generally adopts the one-size-fits-all method of cutting knives, but when the one-size-fits-all method is used, the packaging material will bend, resulting in uneven or skewed cuts, which will affect product quality. Because it is relatively long, the middle part will be concave under the action of gravity, so the force on both sides and the center of the packaging material will be uneven, which will cause the packaging material to wrinkle during transmission

Abstract

The invention discloses a fly cutter device of a bag making machine. The device comprises a machine frame, the machine frame is provided with a driving roller and a driven roller, a supporting rolleris arranged below the driving roller, a belt is arranged in front of the driving roller and provided with a fly cutter, a pressing plate is arranged above the belt, and two infrared detectors are arranged in front of the belt. The supporting roller supports the bottom of the center of the driving roller to prevent the middle of the driving roller from being concaved downwards, and a packaging bagon the driving roller is uniform in stress. When the packaging bag needs to be cut, the driving roller stops rotation, the pressing plate presses the packaging bag, the fly cutter moves under conveying of the belt and meanwhile cuts off the packaging bag, and the non-cut portion is not pressed by the fly cutter, thereby not being bent and flat in cut face.

Description

technical field [0001] The invention relates to a bag-making machine flying knife device. Background technique [0002] When the bag making machine is slitting, it generally adopts the one-size-fits-all method of cutting knife, but when the one-size-fits-all method is used, the packaging material will bend, resulting in uneven or skewed cuts, which will affect the product quality. Because it is relatively long, the middle part will be concave under the action of gravity, so that the force on both sides and the center of the packaging material will be uneven, which will cause the packaging material to wrinkle during transmission. Contents of the invention [0003] The invention relates to a flying knife device of a bag making machine, which can solve the above problems. [0004] In order to achieve this purpose, the structure adopted in the present invention is: a bag-making machine flying knife device, including a frame, a driving roller is arranged on the frame, the driv...
