Punching device for paper packaging bag linings

Abstract

The invention aims to provide a punching device capable of realizing precise punching of the inner lining of a paper packaging bag, including a base body, a side positioning device, a front positioning device, a rear positioning device, an upper pressing device and a punching device. The side positioning device, the front positioning device and the rear positioning device are all arranged on the upper surface of the base body, and the upper pressing device and the punching device are fixed on the base body through the support frame. The upper surface of the base body is also provided with a punching plane, the rear positioning device is arranged behind the punching plane, the side positioning devices are arranged opposite to each other and are respectively arranged on both sides of the punching plane, and the front positioning device is arranged in front of the punching plane Reciprocating linear motion can be performed on the upper surface of the base body, and the upper pressing device and the punching device can move up and down relative to the upper surface of the base body. The punching device includes a punch, and a blanking hole is arranged on the punching plane at a position corresponding to the punch. The precise positioning of the inner lining of the paper packaging bag can be achieved through the positioning additional device and the pressing device.

Description

technical field [0001] The invention belongs to the field of paper packaging bag production equipment, in particular to a punching device for the inner lining of paper packaging bags. Background technique [0002] Paper packaging bags are environmentally friendly, beautiful, and feel good, and are deeply loved by consumers.
