Embodiment Construction

[0017] Below in conjunction with accompanying drawing, the present invention will be further described:

[0018] like figure 1 , figure 2 As shown, a valve bag tongue automatic folding mechanism, its structure includes:

[0019] A fixed piece 5 is located in the M-shaped pressure edge 101 on the side of the valve pocket 1 close to the tongue 102 and is arranged longitudinally along one side of the valve pocket. The middle part of a movable piece 6 is connected to the fixed piece 5 through the first hinge shaft 9 . Wherein, the tongue opening 102 of the valve pocket 1 and the M-shaped bead 101 on one side of the valve pocket are formed in the previous process. It is laid on the frame 8 working surface of this machine.

[0020] The relationship between the fixed piece 5 and the movable piece 6 is preferably that the fixed piece 5 is on the top and the movable piece 6 is below, which is more conducive to the forward movement of the valve pocket 1, and the deflection angle of ...

Abstract

An automatic folding mechanism for a valve bag tongue port belongs to matching mechanisms of packaging machines. The automatic folding mechanism comprises a fixed sheet which is positioned in an M-shaped blankholder in one side close to the tongue port in the valve bag and is vertically arranged along one side of the valve bag. The central section of a movable sheet is connected to the fixed sheet through a first articulated shaft. The outer end of the movable sheet is hinged to a second drive unit which drives the movable sheet to deflect at a certain angle. The inner end of the movable sheet is a folding end corresponding to the valve bag tongue port. A valve bag pressure plate controlled by a first drive unit is provided at the top of a frame. The mechanism of the invention replaces manual operation, thereby realizing automatic folding, saving labor cost, and improving production efficiency.

Description

technical field [0001] The invention relates to an auxiliary mechanism of a packaging machine, in particular to an automatic folding mechanism of a valve pocket tongue. Background technique [0002] Valve bag, commonly known as: paste bottom bag, is a popular packaging bag in the world at present. The material is fed from the top or bottom valve port. Special filling equipment is used. After filling the material, it is packed into a cube. The stacking is neat and beautiful. However, when making the valve pocket, it is necessary to set M-shaped hemmings and protruding tongues on both sides of the bag body, and manually fold the tongue of the valve pocket inward at an angle of 90 degrees to form the valve pocket after sewing. Due to the large production batches of the valve pockets, a large number of workers are required for manual operation, which not only increases labor costs, but also reduces work efficiency. Contents of the invention [0003] The object of the present ...
