Problems solved by technology

This makes the falling drop of the packaging bag larger, and it is easy to cause the plastic bag that has been packed to escape at the sealing position during the falling process, and it is easy to burn it when sealing; another problem is that the falling position of the packaging bag is not necessarily accurate. Its predetermined sealing position does not necessarily correspond to the heat sealing device, and the packaging bag is easy to tilt

Abstract

The invention discloses a sealing device for a plastic bag packaging machine. The sealing device is connected with the rear end of the plastic bag packaging machine, and is used for sealing the sealing position of a packaging bag in which plastic bags are loaded; the sealing device comprises a rack and a clamping output device, and is characterized in that the rack at the rear end of the plastic bag packaging machine is also provided with a lift platform, a heat sealing device and a bag discharge device; after being folded, batches of plastic bags produced on a bag making machine are automatically loaded into the packaging bag by the plastic bag packaging machine, and the packaging bag in which plastic bags are loaded is conveyed to clamping manipulators of a clamping input device; the packaging bag is output to the lift platform by the clamping manipulators, and the predetermined sealing position of the packaging bag is corresponding to a heat sealing tool or a heating wire, and then, the lift platform falls so as to avoid the clamping manipulators returning; then, sealing is implemented by the heat sealing device, and the sealed packaging bag is discharged by the bag discharge device. The sealing device disclosed by the invention has the advantages of being high in automation degree, flat and attractive in packaging, high in speed, high in efficiency and the like.

Description

technical field [0001] The invention relates to a packaging machine. Specifically, it is a sealing device for packaging plastic bags with packaging bags. Background technique [0002] The sealing device of the plastic bag packaging machine is installed on the plastic bag packaging machine, and is used for heat sealing the opening position of the packaging bag loaded into the plastic bag, so as to facilitate storage, sale and use. Application publication number CN103935567A, published on July 23, 2014, discloses a plastic bag folding and packaging machine (hereinafter referred to as reference document 1), which mainly includes: a folding and loading device, an opening device, and a clamping and output device. Its basic function is to fold the high-cost plastic bags produced on the bag making machine in half and put them into packaging bags. Application publication number CN104003027A, published on August 27, 2014, discloses an automatic bagging device for plastic bags (here...
