Valve sack forming assembly line and control method thereof

Abstract

The invention relates to a valve sack forming assembly line and a control method thereof. Two auxiliary workbenches are symmetrically disposed for gluing, shaping and sealing treatment of the two endsof valve sacks at the same time, a conveying mechanism performs conveying, a valve sack pre-assembling area, a valve sack gluing area and a valve sack forming area are sequentially disposed in cooperation, an end cutting mechanism for cutting ends of valve sacks to conveniently place valve port paper and a valve sack pre-adjusting mechanism for pre-assembling initial positions of the valve sacksare disposed corresponding to the valve sack pre-assembling area. A valve sack gluing mechanism for gluing two ends of the valve sacks is disposed corresponding to the valve sack gluing area. A valvesack sealing mechanism for sealing the valve sacks is disposed corresponding to the valve sack forming area. Operation is controlled by a controller. The valve sack forming assembly line automaticallyforms the valve sacks, gluing, folding, shaping and other core processes are completed mechanically with the aid of manpower, work efficiency is improved, labor cost is low, efficiency is high, the formed valve sacks are neat and not prone to coming unglued, the reject rate is low, environmental friendliness and energy conservation are realized, and production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of forming, feeding, opening or assembling of containers or receptacles related to packaging, in particular to a valve pocket forming line and a control method thereof. Background technique [0002] The valve bag is a kind of packaging bag mainly used for packing food powder, chemical powder, chemical fertilizer, synthetic material, explosives, grain, salt, minerals and other powdery or granular solid materials and flexible items. [0003] The valve bag is fed from the top or bottom valve port, and special filling equipment can be used. After filling the material, it will be packed into a cube. The stacking is neat and beautiful, and it belongs to the environmental protection bag. [0004] However, the existing valve pockets are mainly formed through manual processing, including putting valve paper on one end of the semi-finished bag, gluing, folding, and shaping at both ends until the valve pocket is formed...

AI Technical Summary

Problems solved by technology

[0005] The invention solves the problem that in the prior art, the forming of valve pockets is mainly done manually, which results in strong manual dependence and low efficiency. High, increase the cost of the problem, provides an optimized valve pocket forming line and its control method
