Edge folding and shape fixing mechanism for woven bag production assembly line

Abstract

The invention discloses an edge folding and shape fixing mechanism for a woven bag assembly line, and relates to manufacturing equipment for a woven bag with an inner bag. Edge folding and bag openingshape fixing automation after bag sleeving can be achieved. The edge folding and shape fixing mechanism for the woven bag assembly line comprises a bracket, a main air cylinder, a sliding frame, a fixing frame, a woven bag rotating mechanism, an edge wrapper and a high-frequency sealing machine, and the main air cylinder, the edge wrapper, the high-frequency sealing machine and the sliding frameare installed on the bracket. The edge folding and shape fixing mechanism for the woven bag assembly line is characterized in that a main air cylinder sleeve is installed on an installing support of the bracket, the other edge of the installing support is connected to a bracket supporting plate, and the main air cylinder piston end is installed on a connecting plate of the fixing frame; the sliding frame comprises sliding rods and supporting side plates, the side plates are arranged at the two ends of the sliding rods, the sliding rods are perpendicularly and fixedly connected with the side plates, and sliding blocks are arranged at the lower ends of the side plates and installed on sliding rails of the bracket; and the fixing frame comprises installing clamping blocks fixedly installed onthe sliding rods and a fixing frame lower longitudinal plate and a fixing frame upper longitudinal plate which are longitudinally connected between the installing clamping blocks. According to the edge folding and shape fixing mechanism for the woven bag assembly line, the problems that in the manual edge turning process, the speed is low, the edge turning quality is unstable, the manual labor intensity is high, and the defective product rate is high are solved, and the qualification rate of the produced woven bag is significantly increased.

Description

technical field [0001] The invention relates to a woven bag production equipment with an inner bag, in particular to a hemming-fixing mechanism used on a woven bag production line. Background technique [0002] In the production process of woven bags, in order to better pack fine powder materials, increase the safety of woven bag packaging, and prevent the woven bag from being accidentally damaged and cause the powder material to be packaged to leak, it is often necessary to clean the mouth of the woven bag. Folding and fixing, wrapping and fixing the exposed part of the edge of the bag that is easy to pick up, this can overcome the phenomenon that the outer bag is easy to tear due to the material structure; at present, on the production line of woven bags, most manufacturers use manual folding for this process. The edge is fixed, so there are problems such as slow speed, unstable quality of hemming, high labor intensity, and high defective rate. Contents of the invention ...

[0002] In the production process of woven bags, in order to better pack fine powder materials, increase the safety of woven bag packaging, and prevent the woven bag from being accidentally damaged and cause the powder material to be packaged to leak, it is often necessary to clean the mouth of the woven bag. Folding and fixing, wrapping and fixing the exposed part of the edge of the bag that is easy to pick up, this can overcome the phenomenon that the outer bag is easy to tear due to the material structure; at present, on the production line of woven bags, most manufacturers use manual folding for this process. Edge, fixed, so there are problems such as slow speed, unstable quality of hemming, high labor intensity, high defective rate, etc.
