Threading machine and threading method for portable paper bag

Abstract

The invention relates to full-automatic portable paper bag processing equipment, in particular to a threading machine for a portable paper bag. The threading machine comprises a processing platform, afeeding mechanism, a bag opening mechanism, a punching mechanism, a bag expanding turnover mechanism, threading mechanisms and a discharging mechanism, the processing platform is composed of two flatplates which are horizontally arranged at intervals, in the conveying direction of the paper bag, the feeding mechanism is arranged above the front end of the processing platform, the bag opening mechanism is arranged at the position, below the feeding mechanism, of the processing platform, the punching mechanism is arranged at the position, behind the bag opening mechanism, of the processing platform, the bag expanding turnover mechanism is arranged at the interval between the two flat plates of the processing platform, and is arranged behind the bag opening mechanism, the number of the threading mechanisms is two, the two threading mechanisms are correspondingly arranged on the two sides of the upper end of the bag expanding turnover mechanism, and the discharging mechanism is arrangedat the position, behind the bag supporting turnover mechanism, of the processing platform. The threading machine for the portable paper bag combines a threading method so that the threading work of the portable paper bag can be rapidly completed.

Description

technical field [0001] The invention relates to a full-automatic portable paper bag processing equipment, in particular to a portable paper bag stringing machine and a stringing method thereof. Background technique [0002] Portable paper bag is a relatively common article in people's daily life. It is composed of a handle rope and a bag body. There are rope holes on the bag body. The two ends of the handle rope pass through the rope hole from outside to inside. The clips at both ends of the rope are stuck on the rope holes, so that people can lift the paper bag through the hand-held rope, which provides great convenience for people in life; but in the existing hand-held paper bag processing, the hand-held rope is generally used It is manually inserted into the paper bag, which has the disadvantages of low efficiency and high labor cost. [0003] In the invention patent with the patent application number 201711027727.9, a hand rope threading machine is provided, which integ...

[0002] Portable paper bag is a relatively common article in people's life. It is composed of a handle rope and a bag body. There are rope holes on the bag body. The two ends of the handle rope pass through the rope hole from outside to inside. The clips at both ends of the rope are stuck on the rope holes, so that people can lift the paper bag by the hand-held rope, which provides great convenience for people in life; but in the existing hand-held paper bag processing, the hand-held rope is generally It is manually inserted into the paper bag, which has the disadvantages of low efficiency and high labor cost

[0003] In the invention patent with the patent application number 201711027727.9, a hand rope threading machine is provided, which integrates bag body conveying, hand rope conveying, heading, cutting and bag threading, instead of manual operation, realizing However, there are still the following problems: the rope-threading device and the rope-drawing device are a fixed station. After the bag body is transported to this station, it needs to complete processes such as threading and rope-drawing, which leads to the fact that the bag body is in this station. The position needs to stay for a long time, which leads to low production efficiency of the overall equipment and cannot meet the processing and production needs of paper bag stringing
