The work aims to solve the problems of quality defect of strip bags in production process and the waste of latex caused by cleaning of glue cylinder as well as the environmental pollution in view of that the latex quality degrades due to long-time exposure in air, thus affecting the effect of latex on the strip boxes. A new type of automatic glue spraying control device for strip boxes was designed. Through the study on glue spraying control technology and combined with gluing device, pressure plastic barrels, PLC controller and control program, the automatic synchronous glue spraying, precise glue coating, latex allowance detection and alarm of the strip box in the strip box packaging machine were realized by photoelectric detection, shift control of PLC, high-pressure gluing by glue gun and glue supply by pressure pump. After the installation of the automatic glue spraying control device for strip box, the sealed and pollution-free storage and transportation of latex were realized, and the functions of positioning detection of strip box, accurate gluing with glue gun, pressure glue supply and glue allowance detection were added. The glue spraying quality of strip box was improved, the qualified rate of products was guaranteed, the quality of latex was enhanced and the consumption of latex was reduced. The automatic glue spraying control device of strip box can improve the glue spraying quality of strip box, reduce the consumption of latex, decrease the pollution of latex to the environment, increase the operation rate of equipment and reduce the risk of defective strip box into the next process and can be promoted and applied to all strip box packaging equipment in the tobacco industry.
