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 the rigidity and paper cutting accuracy. Generally, it is only about 1.3 meters, and the longest is no more than 1.8 meters. The rolls are 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. It is only possible to continue processing 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.

Embodiment 1

[0043] Such as image 3 , 4 Shown is a paper suction device of a V-shaped box pumping paper towel folding machine, which includes two left folding rollers 2, right folding rollers 21 and two sets of knife shafts that cooperate with the folding rollers on the horizontal plane. The knife shafts include horizontal Arrange and coordinate the fixed knife shaft 13 (23) and the moving knife shaft 12 (22) of rotating paper cutting, this moving knife shaft 12 (22) is positioned at 45 ° of folding paper roller obliquely above and cooperates with folding paper roller 2 (21) and rotates. Folding paper roller 2 (21) is provided with suction passage and the air chamber that communicates with it to form air valve, and this air valve is the air chamber that forms between the valve body and the roller surface or end face of two ends of folding paper roller, and folding paper roller The two ends have the end surfaces at both ends and the roller surfaces at both ends; a paper feeding air chambe...

Embodiment 2

[0051] Compared with Embodiment 1, this embodiment sets the ports of the paper feeding suction channel on the end faces of the two ends of the paper folding roller, cancels the air chamber on the roller surface, and additionally sets the paper feeding air chamber, that is, the air valve; the port of the folding paper suction channel That is, the origami air valve formed by the origami suction hole and the origami air chamber is set on the outer ring of the end face of the origami roller, and the port of the paper feeding suction channel is the paper feeding air valve formed by the paper feeding suction hole and the paper feeding air chamber. The inner rings at both ends of the roller, the paper feeding suction holes and the folding paper suction holes can be arranged along the same circle, or can be arranged along two circles with different radii respectively, and the suction channel is set to penetrate through the inside of the paper folding roller along the axial direction. T...

Embodiment 3

[0053] Compared with Embodiment 1, the difference between this embodiment and the first embodiment is that both the paper feeding suction hole and the folding paper suction hole are arranged on the roller surfaces at both ends of the paper folding roller, and the paper feeding suction hole and the folding paper suction hole are respectively provided with corresponding There is an air chamber on the roll surface, which is the air valve. At the same time, the installation structure of the air valve is slightly different. The knife shaft includes the upper left knife shaft and the upper right knife shaft that are arranged horizontally and cooperate with the paper cutting. The upper left knife shaft and the upper right knife shaft are located on the Above the origami roller and cooperate with the origami roller to rotate. The paper folding roller is provided with a cutting knife corresponding to the upper knife shaft along its circumference. Its paper-absorbing method and working ...

Abstract

The invention discloses a paper suction method of a folder for V-shaped box drawing type facial tissues. An air suction port is respectively arranged at two ends of a paper folding roller, and negative pressure is formed by simultaneously sucking air from the air suction ports at the two ends to absorb facial tissues. The invention also discloses a device utilizing the paper suction method. The device comprises two paper folding rollers which rotate side by side in a coordinated way and two cutter shafts which fit with the paper folding rollers to cut paper. Air suction channels are arranged in the paper folding rollers, and air suction holes communicated with the air suction channels and air valves controlling the air suction channels are arranged on the paper folding rollers. The deviceis characterized in that the air suction holes are arranged at the two ends of the roller surface of each paper folding roller, and the air suction holes at the two ends are mutually communicated through the air suction channels. The invention has the advantages of high efficiency, high paper folding accuracy, low energy consumption and low production and running costs.

Description

technical field [0001] The invention relates to the technical field of toilet paper folding machines, in particular to a paper suction method for a V-shaped box pumping paper towel folding machine and a paper suction device used in the method. Background technique [0002] Daily paper has penetrated into all aspects of people's lives. With the improvement of living standards, people's demand for boxed paper towels is increasing. In recent years, the production focus of the domestic market is roll paper. Therefore, boxed paper towels origami The relatively insufficient research and development of equipment has resulted in the failure of the existing box tissue folding machines to meet market demand. 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 distributio...
