Plastic bottle airbag cutting device and method

Abstract

The invention discloses a plastic bottle airbag cutting device and method. Cylindrical airbags can be cut. The plastic bottle airbag cutting device comprises an inner guide groove disc, an outer guidegroove disc and an circular arc cutter, wherein the inner guide groove disc is circular and can rotate around the center of a circle; the outer guide groove disc is arranged on one side of an inner guide groove; notches matched with the shapes of the airbags are formed in the outer periphery and the arc surface of the inner guide groove disc; the circular arc cutter is arranged below the inner guide groove disc and faces the outer guide groove disc; the airbags of a plastic bottle is clamped between the inner guide groove disc and the arc surface; and the plastic bottle rotates around the circular arc cutter under the drive of the rotation of the inner guide groove disc to realize separation of the airbags and a bottle body. The plastic bottle airbag cutting method comprises the steps that A, the plastic bottle is conveyed to a plastic bottle airbag cutting device through a guide mechanism; B, the airbags on the plastic bottle are in contact with and matched with the notches of the inner guide groove disc and the outer guide groove disc; and C, under the driving of the rotation of the inner guide groove disc, the plastic bottle rotates around the fixed circular arc cutter, and after cutting is completed, the airbags are separated from the plastic bottle. The plastic bottle airbag cutting device and method have high universality and can ensure the cutting effect of the airbags.

Description

technical field [0001] The invention relates to the technical field of plastic bottle processing, in particular to a plastic bottle airbag cutting device and method. Background technique [0002] During the processing of plastic bottles, the air bag on the mouth of the processed plastic bottle needs to be cut off. The invention patent with the application number CN201720731276.6 discloses a bottle cutting machine, which includes a circular arc cutter device, an outer guide plate and an inner guide plate used to cooperate with the outer guide plate to clamp the bottle body. The disk is used to drive the bottle body to rotate around the arc cutter device, and the rotation center of the arc cutter device coincides with the rotation center of the inner guide groove disk. When the plastic bottle is sent to the bottle cutter, the thread of the plastic bottle is clamped by the outer guide plate and the inner guide plate, and the side of the neck plate in the inner guide plate is p...
