Sterile cavity paper barrel forming device

Abstract

The invention discloses a sterile cavity paper barrel forming device, relates to a filling machine, and aims at avoiding the hidden danger that since an electric heater cannot apply pressure to a packaging part, the fixing strength is insufficient, and bag breakage is likely to happen. According to the technical scheme, the sterile cavity paper barrel forming device is characterized in that the sterile cavity paper barrel forming device comprises a shell, a filling pipe arranged in the shell and a transverse seal electrode arranged on the shell; two connecting barrels are fixed to the shell and are in sliding connection with polished shafts, an inner fixing plate is fixed between the inner ends, extending into the shell, of the two polished shafts, the transverse seal electrode is fixedlyarranged on the inner fixing plate, and an outer fixing plate is fixed between the outer ends, located at the shell, of the two polished shafts; and a thrust air cylinder is fixed to the outer wall ofthe shell, and a piston rod of the thrust air cylinder is fixed to the outer fixing plate. According to the sterile cavity paper barrel forming device, glue hot melting and solidification are achieved in the pressure state, accordingly, the glue fixing strength on the two sides of cylindrical paper rolls is improved, and the hidden danger of bag breakage is effectively reduced.

Description

technical field [0001] The present invention relates to a filling machine, more particularly, it relates to an aseptic cavity paper tube forming device. Background technique [0002] In the liquid food filling process, the manufacturing technology of forming brick-shaped packaging boxes or diamond-shaped packaging boxes from continuous packaging materials has been widely used. [0003] The production process of the filling machine generally includes, the packaging material is formed into a tube, that is, the packaging material is guided to bend and the two sides of the packaging material are heat-sealed to form a cylindrical hollow paper tube; food injection, that is, the food to be filled through the pipeline Inject into the hollow paper tube; volume forming and sealing, that is, heat seal the two ends of the cylindrical paper tube and cut off, so as to make a paper bag with both ends sealed and wrapped with the food to be filled; the filling box is shaped, that is, through...

AI Technical Summary

Problems solved by technology

[0005] However, in practical application, it is found that when the filling capacity is more than 500ml, due to the long length of the sealing strip on the side, when the above solution is used for packaging, the electric heater cannot apply pressure to the packaging part, resulting in insufficient fixing strength. There is a hidden danger of easy packet breakage; therefore, a new solution needs to be proposed to solve this problem
