Paper folding roll structure for folding machine for boxed extraction type paper towels

Abstract

The invention provides a paper folding roll structure for a folding machine for boxed extraction type paper towels, which comprises a paper folding roll body. Suction control openings are arranged on both ends of the paper folding roll body, a plurality of paper conveying and folding suction holes which are axially arrayed are disposed on the surface of the paper folding roll body, the paper conveying and folding suction holes are communicated with airflow channels in the paper folding roll body, and a spacing part is arranged in the middle of each airflow channel and divides the airflow channel penetrating through the inside of the paper folding roll into two sections. During operation, periodic communicating air suction of each section of airflow channels and each of respective suction control openings of the airflow channels is realized. The problem that fluctuation of airflow inside an existing paper folding roll is high can be effectively solved, accordingly, the paper folding roll structure is higher in efficiency and paper folding precision while energy consumption and running cost are reduced, paper conveying and folding speed is faster, actual production requirements can be met completely, the paper folding roll structure and body paper production equipment can be easily combined to form a production line, and automatic operation is realized.

Description

technical field [0001] The invention relates to the technical field of toilet paper folding machines, in particular to a paper folding roller structure used in a box-pumping paper towel folding machine. Background technique [0002] As is known in the industry, traditional box-pumping tissue folding machines generally use unilateral suction to sequentially perform the actions of horizontal paper cutting, paper feeding, and paper folding, and finally fold the paper towels together alternately, but the existing box-pumping tissue folding The machine is limited to its own structural characteristics, and generally has the disadvantages of low work efficiency, inability to form a continuous production line, high energy consumption, and low origami precision, so it has not been popularized. Although there is also a box-pumping paper towel folding machine that performs synchronous paper feeding suction and synchronous folding paper suction by providing suction control ports and cor...

Problems solved by technology

[0002] As is known in the industry, traditional box-pumping tissue folding machines generally use unilateral suction to sequentially perform the actions of horizontal paper cutting, paper feeding, and paper folding, and finally fold the paper towels together alternately, but the existing box-pumping tissue folding The machine is limited to its own structural characteristics, and generally has the disadvantages of low work efficiency, inability to form a continuous production line, high energy consumption, and low origami precision, so it has not been popularized.

Although there is also a box-pumping paper towel folding machine that performs synchronous paper feeding suction and synchronous folding paper suction by providing suction control ports and corresponding air valve structures at both ends of the paper folding roller in China. The method of synchronous suction at both ends is more advanced than the single-side suction method of the traditional box-pumping tissue folding machine, and the work efficiency is higher, but there is still a serious problem, that is, the synchronization of both ends of the folding roller is adopted. The way of suction, as far as the current technology is concerned, it is difficult to achieve the effect of synchronous suction at both ends. The actual situation is often due to the difference in the phase of the vacuum suction cups, which leads to the first suction and first closing of the suction control ports at the left and right ends. The asynchronous mixing and suction will make the airflow inside the folding roller fluctuate greatly, which will seriously affect the subsequent processing and the quality of the finished product
