Film blowing and printing all-in-one machine

Abstract

The invention discloses a film blowing and printing all-in-one machine. The film blowing and printing all-in-one machine is characterized by being composed of a winding part, a double-color printing part, a traction part and a film blowing main machine part which are arranged left and right, wherein the film blowing main machine part comprises a film blowing main machine and a forming mold connected to an outlet of the film blowing main machine, a cooling air ring, a cooling air pipe and a herringbone frame are arranged above the forming mold, the cooling air ring, the cooling air pipe and theherringbone frame are installed on a film blowing machine frame, a material passing gap at the top of the herringbone frame can be elastically changed, the traction part comprises a buckling device,a front traction roller, an opening device, a tripping detection device and a rear traction roller, the buckling device, the front traction roller, the opening device, the tripping detection device and the rear traction roller are installed on the film blowing machine frame, and a winding machine frame of the winding part and a printing machine frame of the double-color printing part are detachably connected with the film blowing machine frame through a connecting rod arranged at the top of the winding machine frame and the top of the printing machine frame. The film blowing and printing all-in-one machine is flexible in combination, small in occupied space, high in production speed, capable of realizing the functions of tripping detection and double-color printing and capable of avoidingthe phenomenon that a film material joint is clamped.

Description

technical field [0001] The invention relates to a production equipment for a self-sealing film bag, in particular to an integrated film blowing and printing machine. Background technique [0002] The production equipment for self-sealing film bags currently on the market, including blown film printing all-in-one machines, are fixedly connected to each other, and the combination is not flexible. In addition, to achieve two-color printing, two sets of printing units must be arranged front and back, occupying a lot of space. and it cannot realize the tripping detection function, which will easily lead to the appearance of a large number of waste products; in addition, when the self-sealing film bag tube blown out by the forming mold is flattened by the gable frame, due to the material passing gap at the top of the gable frame It is fixed, and the feeding gap cannot be large, so when the film material joint is large, the film material joint is easy to get stuck when passing thro...

[0002] The production equipment for self-sealing film bags currently on the market, including blown film printing all-in-one machines, are fixedly connected to each other, and the combination is not flexible. In addition, to achieve two-color printing, two sets of printing units must be arranged front and back, occupying a lot of space. and it cannot realize the tripping detection function, which will easily lead to the appearance of a large number of waste products; in addition, when the self-sealing film bag tube blown out by the forming mold is flattened by the gable frame, due to the material passing gap at the top of the gable frame It is fixed, and the feeding gap cannot be large, so when the film material joint is large, the film material joint is easy to get stuck when passing through the material feeding gap, which affects the normal production operation; finally, because the mouth of the self-sealing film bag With zipper chain, the thickness of the zipper chain is thicker, and the effect of cooling it according to the traditional cooling air ring is poor, so the production speed will be slower
