Automatic glue spraying device of packaging bag production line

Abstract

The invention discloses an automatic glue spraying device of a packaging bag production line. The automatic glue spraying device of the packaging bag production line comprises a rack and a paper bag conveying mechanism. The rack is arranged above the paper bag conveying mechanism; spray gun mechanisms and a controller are disposed on the rack; each spray gun mechanism comprises a spray gun; the spray guns are connected with a glue feeding tank through glue tubes; the spray guns are fixed to the rack through sliding blocks; the controller controls a hauling mechanism to drive the sliding blocks to move front and back on the rack; a hot air discharging mechanism is further disposed on the rack; and an air outlet of the hot air discharging mechanism faces the spray gun mechanisms. The automatic glue spraying device, provided by the invention, of the packaging bag production line is convenient to operate, can conduct uniform spraying and is high in spraying efficiency; and meanwhile, the hot air discharging mechanism is arranged so that glue can be heated appropriately and the situation that the automatic glue spraying device cannot be used due to solidification of the glue is prevented.

Description

technical field [0001] The invention relates to the field of packaging materials, in particular to an automatic glue spraying device for a packaging bag production line. Background technique [0002] With the development and progress of society, there are more and more demands for packaging bags in the market, and there are more and more requirements for the types of packaging bags. Most of the packaging bags are made of multi-layer paper materials. In the process, it is necessary to spray glue between the outermost layer of paper material and the middle layer. Most of the existing spray glue is sprayed manually, which has low efficiency and poor safety. With the development of technology, mechanical reciprocating Type of glue spraying equipment, but the glue spraying equipment also has defects. For example, if the glue to be sprayed is easy to solidify, it will cause the spraying equipment to be unusable. Therefore, a glue spraying device with high efficiency and wide appli...

[0002] With the development and progress of society, there are more and more demands for packaging bags in the market, and there are more and more requirements for the types of packaging bags. Most of the packaging bags are made of multi-layer paper materials. In the process, it is necessary to spray glue between the outermost layer of paper material and the middle layer. Most of the existing spray glue is sprayed manually, which has low efficiency and poor safety. With the development of technology, mechanical reciprocating Type of glue spraying equipment, but the glue spraying equipment also has defects. For example, if the glue that needs to be sprayed is easy to solidify, it will cause the spraying equipment to be unusable. Therefore, a glue spraying device with high efficiency and wide application range is very Needed
