Full-automatic inner container woven bag inner folding edge winding pre-welding device

Abstract

The invention discloses a full-automatic inner container woven bag inner folding edge winding pre-welding device. An upper suction cover assembly comprises an upper guide rod cylinder, an upper suction plate and an upper suction cup, a lower suction cover assembly comprises a lower guide rod cylinder, a lower suction plate and a lower suction cup, an air suction positioning assembly comprises an air suction plate, a linear guide slider, a double-position cylinder and a mounting supporting frame, a ultrasonic spot welding assembly comprises two groups of upper and lower ultrasonic spot weldingmachines, an air cylinder, a linear bearing and a guide rod, a packaging woven bag comprises a woven bag outer bag and a woven bag inner container, the upper suction assembly and the lower suction assembly respectively perform opposite movement and back movement, the air suction plate moves towards the woven bag inner container along the linear guide rail slide block under the driving of the double-position air cylinder, and the upper ultrasonic spot welding machine and the lower ultrasonic spot welding machine carry out opposite movement and finish spot welding on packaging woven bags. According to the full-automatic inner container woven bag inner folding edge winding pre-welding device, the reject ratio is greatly reduced, the automation degree is high, the positioning is accurate, andthe rate of finished products and the welding efficiency are greatly improved.

Description

technical field [0001] The invention relates to the technical field of welding devices, in particular to a fully automatic pre-welding device for inner flanging and mouth wrapping of inner liner woven bags. Background technique [0002] At present, the traditional packaging woven bag includes a woven bag inner liner and a woven bag outer bag. The inner liner is usually about 5cm longer than the outer bag due to packaging requirements. The finished packaging woven bag is welded directly through ultrasonic welding, so that the inner bag and the outer bag are neatly combined. Before welding, the inner liner and the outer bag are generally aligned manually, and the edge is folded and wound before welding, which can easily cause unevenness at the interface between the inner liner and the outer bag of the finished packaging woven bag, and the yield rate is low. The production capacity is also relatively low, which greatly affects the economic benefits of the enterprise. Content...
