High-strength and high-toughness heat-sealing bottom-pasting bag folding and mouth pasting device

Abstract

The invention relates to a high-strength and high-toughness heat-sealing bottom-pasting bag folding and mouth pasting device, which comprises a folding station and a bottom pasting station which are arranged in sequence; a folding device is arranged at the folding station; the folding device comprises a turnover assembly, an angle folding assembly and an air blowing assembly; the turnover assembly comprises two sets of turnover mechanisms which are symmetrically and rotationally arranged up and down and form a woven bag containing space; the turnover mechanisms are used for opening and closing bag mouths of woven bags; after extending to the junction of the two sets of turnover mechanisms, the angle folding assembly moves outwards and is matched with the turnover mechanisms to smoothen the transverse folding wing positions on the two sides of the bag mouth and press the wrap angle position of the bag mouth at the same time; the air blowing assembly is arranged on the contact face of the angle folding assembly and the woven bag; the bag mouth is closed by the turnover mechanisms; and the air blowing assembly blows air, so that the angle folding assembly is separated from the woven bag. According to the invention, the technical problem that the bottom pasting deviation occurs due to the fact that the folding assembly is easily taken out of the wrap angle when being pulled out is solved.

Description

technical field [0001] The invention relates to the field of packaging machinery, in particular to a high-strength and high-toughness heat-sealable bottom bag folding living device. Background technique [0002] At present, the valve bag is widely used in the packaging and transportation of materials. After the valve bag is processed by processing equipment, one of the ports needs to be folded to form a valve port structure. In the prior art, the processing personnel usually fold the valve bag manually, and then paste the bottom after the processing personnel fold it. It can be known from the above that the valve pockets in the prior art are folded manually, resulting in low processing efficiency of the valve pockets. [0003] The invention patent with the Chinese patent application number CN201110097795.9 discloses a valve pocket folding forming device and a valve pocket folding method. The valve bag folding and forming device includes: a bracket, a positioning turning de...

Problems solved by technology

[0004] However, during the use of the equipment, after the inserting knife cooperates with the inserting plate to complete the folding, the folded corners are easily taken out due to the existence of friction during the drawing out of the inserting knife, which will affect the final paste effect.
