Problems solved by technology

[0004] 1. Low efficiency, unable to form a continuous production line
The origami roller of the traditional V-shaped box tissue folding machine is limited by rigidity and paper cutting accuracy, generally only about 1.3 meters, and the longest is no more than 1.8 meters. Although the maximum number of origami can reach 600-800 sheets per minute, due to its The origami roller is relatively short, and the base paper produced is generally more than two meters long. Therefore, the existing V-shaped box tissue folding machine cannot form a continuous production line with the machine for producing base paper. The width can be continued on the existing V-shaped box paper towel folding machine, which not only greatly limits the production efficiency, but also consumes time, electricity, paper and labor, resulting in a lot of unnecessary waste
[0005] 2. High energy consumption and low origami precision
The existing V-shaped box paper towel folding machine is limited to its structural features, and the folding efficiency can only be improved by increasing the rotating speed, but its suction channel is a blind hole, and the suction can only be carried out from one end to the other end. At this time, the inhalation time of the inhalation channel is very short. In such a short time, the 1.3-meter-long inhalation channel must be pumped into negative pressure from one end to the other, and it is inevitable that there will be uneven inhalation. The consequence is that the corners of the paper towels appear, which greatly affects the orderliness of the paper towels
In order to reduce this error, we can only increase the power of the vacuum pump, but even so, the error can only be controlled within a certain range
And every time a model of vacuum pump increases, its cost also increases greatly.
[0006] At present, although there is a box-pumping paper towel folding machine structure abroad, such as image 3 As shown, the paper cutting is completed by the cooperation of the movable knife shaft and the fixed knife shaft, and the paper folding is completed independently by the paper folding rollers. There is an air valve on each side of the paper folding rollers, and only one folding function is completed at the same time. The above structure is not only complicated in structure and high in cost. At the same time, because the paper cutting is completed on the moving knife shaft, and the paper is sent to the folding roller for folding after the paper cutting is completed, it is easy to cause misalignment, resulting in the phenomenon that the paper is not folded neatly in half

Abstract

The invention discloses an air suction / exhaust method and structure of a V-shaped box facial tissue folding machine. The two ends of each tissue folding roller with a cutter on the roller surface are provided with air suction control ports in mutual communication respectively; air suction is performed at the air suction control ports at the two ends at the same time to form a negative pressure and absorb the facial tissue; and thus the processes of tissue feeding, cutting and folding are realized on the same tissue folding roller. The structure disclosed by the invention comprises two parallel tissue folding rollers and two cutter shafts; the roller surface of each tissue folding roller is axially provided with a cutter corresponding to the cutter shaft; each side of each tissue folding roller is provided with a tissue feeding air suction control port, a tissue folding air suction port and a corresponding air valve; the tissue feeding air suction control port and the tissue folding air suction control port are mutually communicated through an air suction channel; and air suction holes are correspondingly communicated with the corresponding air suction channel to form a structure realizing respective and synchronous air suction of the tissue feeding air suction control port and the tissue folding air suction control port on the two sides of the tissue folding roller. The invention has the advantages of high efficiency, high tissue folding precision, low energy consumption and low production and operation cost.

Description

technical field [0001] The invention relates to the technical field of toilet paper folding machines, and more specifically relates to a method and structure for sucking and deflated air of a V-shaped box pumping paper towel folding machine. Background technique [0002] The main structure of the traditional V-shaped box paper towel folding machine is as follows: figure 1 , 2 As shown, it includes a left upper knife shaft 1, a right upper knife shaft 11, a left folding paper roller 2, and a right folding paper roller 21 in a #-shaped distribution. There are air chambers at both ends, three alternate suction passages communicate with the air chamber at one end, and the other three suction passages communicate with the air chamber at the other end. Air hole, when working, the paper towel can be adsorbed on the folding roller through the suction hole, so that the air chambers at both ends of the folding roller alternately suck in and close, so that the left and right two grou...
