Folding opening forming assembly line facilitating machining of valve bags of different specifications

Abstract

The invention relates to the technical field of valve bag machining, in particular to a folding opening forming assembly line facilitating machining of valve bags of different specifications, which comprises a working frame, and the working frame comprises a machine frame, two conveying mechanisms, supporting frames and an adjusting mechanism; the two conveying mechanisms are both arranged in the middle of the machine frame and are arranged in a bilateral symmetry mode in the conveying direction; the two supporting frames are arranged on the two sides of the two conveying mechanisms correspondingly and arranged in a bilateral symmetry mode in the conveying direction; a plurality of folding opening forming stations are arranged on the supporting frames in the conveying direction; and the adjusting mechanism drives the two supporting frames to be close to or away from each other and enables the conveying mechanism located on the same side with the supporting frames to move horizontally along with the supporting frames. The folding opening forming assembly line provided by the invention is reasonable in structural design, the position of a folding forming station on a folding forming assembly line can be conveniently adjusted, then valve bags of different specifications can be well folded and formed, and the actual requirement for valve bag machining can be better met.

Description

technical field [0001] The invention relates to the technical field of valve pocket processing, in particular to a folding forming line for conveniently processing valve pockets of different specifications. Background technique [0002] Valve bag, commonly known as paste bottom bag, is a kind of packaging bag, which is fed from the top or bottom valve port. Special filling equipment is used. After filling the material, it is packed into a cube. When the filling is completed, the contents will be squeezed from the inside. Press and close the valve port to achieve the sealing effect. The stacking is neat and beautiful, and it belongs to the environmental protection bag. Valve bags are mainly used for packing food powder, chemical powder, fertilizer, synthetic materials, explosives, grain, salt, minerals and other powdery or granular solid materials and flexible items. It is especially suitable for export enterprises and can improve the packaging grade of products. [0003] ...

AI Technical Summary

Problems solved by technology

[0003] In the valve bag folding forming line along the conveying direction, it is usually necessary to set up multiple folding forming stations in order to better fold and form the valve bag. The folding forming station on the assembly line can simultaneously perform folding forming on both ends of the valve bag According to actual needs, it is often necessary to process valve pockets of different specifications. Different specifications of valve pockets have different lengths. However, most of the folding forming stations on the existing valve pocket folding forming lines are fixed or the position adjustment of the folding forming stations is extremely cumbersome. , leading to the inconvenient folding and forming of valve pockets of different specifications, which brings great inconvenience to the actual valve pocket processing
