Laminated plastic woven bag pick-up machine

Abstract

The invention discloses a laminated plastic woven bag pick-up machine. The laminated plastic woven bag pick-up machine comprises a rotary drum, a main shaft, a partition plate, a bag bearing device and a conveyor belt, wherein an inner space of the rotary drum is divided into a chamber A and a chamber B by virtue of the partition plate; the partition plate and the main shaft are connected to be an integer which is in slide contact with the inner wall of the rotary drum; an inner hole and a plurality of wall holes are designed in the main shaft; by virtue of the wall holes, the inner hole is communicated with the chamber B; a plurality of groups of radial holes are designed in the outer circular wall of the rotary drum; during working, the inner hole of the main shaft is connected with a vacuum pump; the chamber B and the plurality of groups of radial holes which are positioned in positions communicated with the chamber B are in a negative pressure state, so that laminated plastic woven bags on the negative-pressure positions are absorbed to rotate and move along with the rotary drum; and when certain group of radial holes is rotated away from the chamber B to reach the chamber A, this group of the radial holes loses negative pressure, so that under force of gravity, the laminated plastic woven bags which are originally adsorbed in this group of radial holes are dropped onto the conveyor belt for being sent away. The laminated plastic woven bag pick-up machine has the beneficial effects that heavy manual labor for picking up bags in a laminated plastic woven bag production process can be avoided, the production efficiency is greatly improved, and the economic benefits of businesses are improved.

Description

[0001] The invention relates to the field of packaging machinery, in particular to a laminating plastic woven bag picking machine. technical background [0002] At present, most of the packaging bags used in the domestic packaging industry use laminated plastic woven bags, which are moisture-proof and leak-proof, and are low in cost, economical and practical. The weaving bag enterprise uses a film coating machine to coat a layer of hot-melt plastic film on the surface of the plastic woven tube, and then automatically pulls - automatically cuts - manually picks up the bags - manually folds the bags - manually sends the bags - presses the valve port - manually delivers Valve pocket piece-bottom edge at both ends-finished compound film plastic woven bag, from the existing production technology, the production and manufacture of compound film plastic woven bag, among them, the splicing of compound film plastic woven bag and bag delivery sheet still need to be used A large number o...
