Positive pressure bag opening detection mechanism

Abstract

The invention relates to a positive pressure bag opening detection mechanism. The positive pressure bag opening detection mechanism comprises a bag opening smashing head and a telescopic cylinder. The bag opening smashing head is internally and vertically provided with an air inlet channel and a middle channel from top to bottom; the air inlet channel and the middle channel are communicated; an air inlet pipe is installed inside the air inlet channel and provided with an air inlet connector communicated with the air inlet pipe. The telescopic cylinder is vertically fixed to the upper portion of the air inlet pipe; the air inlet pipe is fixedly connected with the piston rod end of the telescopic cylinder. The bag opening smashing head is internally provided with a lateral channel communicated with the middle channel; a detection floating block is installed inside the lateral channel; an optoelectronic switch is arranged above the bag opening smashing head and fixed to the upper portion of an outlet of the lateral channel through an installation support, and the distance between the optoelectronic switch and the bag opening smashing head is smaller than the height of the detection floating block. The detection time is shortened through synchronization of bag opening and detection; meanwhile, the number of hard self-standing bags with the bag bottoms which can not be opened is decreased through effective bag opening, and the packaging speed and efficiency are improved.

Description

technical field [0001] The invention relates to a bag opening detection mechanism, in particular to a positive pressure bag opening detection mechanism. Background technique [0002] The bag opening mechanism of the prior art, in the case of rigid stand-up bag opening requirements, most of them cannot effectively open the bottom of the bag completely because the packaging bag is relatively hard, let alone effectively detect while opening the bag, resulting in speed And the efficiency becomes worse, which limits the packaging capacity of the machine and cannot meet the requirements of fast and effective packaging. Contents of the invention [0003] The purpose of the present invention is to provide a positive pressure bag opening detection mechanism, which shortens the detection time by synchronizing bag opening and detection, and at the same time, effectively opening bags also reduces the number of rigid stand-up pouches that cannot be opened at the bottom, and improves pa...
