Horizontal sealing and shearing mechanism of inner bag of bag in bag packaging machine

Abstract

A horizontal sealing and shearing mechanism of an inner bag of a bag in bag packaging machine comprises a horizontal sealing servo motor, an S-shaped connection rod, an external pull cross rod, an external ironing block fixing plate, an internal pull cross rod, an internal ironing block fixing plate, external guide rods, internal guide rods and fixed guide blocks. The horizontal sealing servo motor and the fixed guide blocks are fixed on a machine frame, the center of the S-shaped connection rod is fixedly connected with an output shaft of the horizontal sealing servo motor, the external guide rods penetrate the corresponding fixed guide block and the machine frame, the internal pull cross rod and the internal ironing block fixing plate are sleeved on the two external guide rods, the external pull cross rod and the external ironing block fixing plate are fixed at two ends of the two external guide rods respectively, and the internal pull cross rod and the internal ironing block fixing plate are fixed at two ends of the internal guide rods respectively. When the horizontal sealing servo motor rotates, the horizontal sealing servo motor drives the S-shaped connection rod to rotate, accordingly the internal pull cross rod and the external pull cross rod are driven to be close to each other or be unfolded, the external ironing block fixing plate and the internal ironing block fixing plate which are used for fixing horizontal sealing ironing blocks and shears can be closed and opened, and horizontal sealing and shearing are completed.

Description

technical field [0001] The invention relates to a fully automatic packaging machine, in particular to an inner bag making device of a bag-in-bag packaging machine. Background technique [0002] With the development of society and the improvement of people's awareness of environmental protection, people have higher and higher requirements for the environmental protection and safety of pesticides. Human hands cannot touch the pesticide materials, so these pesticides must be packaged in double-bag sealed packaging, referred to as bag-in-bag packaging. For example, powder or granules are first packaged with water-soluble film, and then the packaged inner bag is manually loaded. Secondary sealing packaging in the outer bag, this kind of bag-in-bag packaging scheme that first packs the powder or granule in the inner bag, and then manually puts it into the outer bag and seals it, although the packaging quality is good, but the work efficiency is low and the cost is low. High, can ...

[0002] With the development of society and the improvement of people's awareness of environmental protection, people have higher and higher requirements for the environmental protection and safety of pesticides. Human hands cannot touch the pesticide materials, so these pesticides must be packaged in double-bag sealed packaging, referred to as bag-in-bag packaging. For example, powder or granules are first packaged with water-soluble film, and then the packaged inner bag is manually loaded. Secondary sealing packaging in the outer bag, this kind of bag-in-bag packaging scheme that first packs the powder or granule in the inner bag, and then manually puts it into the outer bag and seals it, although the packaging quality is good, but the work efficiency is low and the cost is low. High, unable to meet mass production requirements

After searching, there is no bag-in-bag packaging machine suitable for double-layer packaging of pesticides at home and abroad.
