Fully-automatic high-speed bag making machine

Abstract

The invention discloses a fully-automatic high-speed bag making machine which comprises a stand and a transmission device, wherein a feeding device, a cutting-off and sealing device and a notching device are sequentially arranged on the stand. The fully-automatic high-speed bag making machine is characterized in that the feeding device comprises a motor, a frame and a film conveying mechanism; a feeding roll is connected to an output shaft of the motor, the feeding roll is in contact with a film coil on the frame when in a working condition, the film conveying mechanism comprises a guide roll, a floating assembly, a linear potentiometer, a transmission motor and a conveying roll connected with the transmission motor; the floating assembly comprises a bracket, a floating roll and a floating roll shaft which are arranged on the bracket, the floating roll shaft is connected with the linear potentiometer, the bracket of the floating assembly is connected with a cylinder; and the motor and the cylinder are electrically connected with the linear potentiometer. Through improving the feeding device, the cutting-off and sealing device and the frame, films are conveyed stably and the advantages of better convenience, rapidness and labor-saving performance are achieved for workers during feeding and blade replacing.

Description

technical field [0001] The present invention relates to an improved invention of a bag-making machine, in particular to an invention of a full-automatic high-speed film bag-making machine. Background technique. [0002] With the market demand for plastic bags, the market demand for film bag making machines is also increasing, and the demand for bag making machines is not only the demand for its quantity, but also the demand for its production efficiency and finished product quality. However, at present, there are several problems in the existing film bag-making machines on the market, as follows: 1. The feeding mechanism of the film bag-making machine, due to the large film roll and heavy weight, is very laborious for manual feeding and handling. Two people are often required to work at the same time; 2. Because the film is easy to stretch, two problems will occur if the front and rear conveying speeds are not synchronized during the conveying process: 1. When the conveying ...
