Description

Technical Field

[0001] The invention relates to the technical field of paper embossing, and in particular to a four-side point-to-point embossing mechanism for paper processing. Background Art

[0002] The purpose of embossing tissue paper is to make the surface of tissue paper more beautiful. In addition, it can also increase the friction between the multiple layers of thin paper of a single tissue paper, improve the integrity, and facilitate users to pick up and use it as a whole without causing single-layer separation. The embossing of tissue paper is formed by embossing roller processing. The tissue paper on the market has patterns printed on only two sides, and the turning edge of the embossing roller and the edge parallel to it are blank. In order to improve the beauty of a single tissue paper and conform to the aesthetic concept of traditional handkerchief and square towel design, our company has designed a tissue paper with point-to-point embossing on four sides to fill the gap in this category of products in the tissue paper industry.

[0003] Existing automatic paper folding machines, such as the Chinese invention patent document "Automatic Paper Folding Machine" proposed with application number: 201410402141.6, should be used to produce four-sided embossed paper. Due to the particularity of the four-sided embossed pattern, the cutting point of each paper drawing must be located in the middle of the pattern, and the pattern is evenly divided to maintain the beauty of the patterns of two adjacent pieces of paper. There is a certain instability in the movement of paper. The distance between the cutting device and the embossing device will increase the probability of the cutting point offset. After the initial knife calibration, the cutting edge will not be able to evenly and parallelly divide the pattern over time. Therefore, the existing embossing mechanism needs to be changed to meet the production of four-sided embossed paper. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a four-side point-to-point embossing mechanism for paper drawing processing.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A four-side point-to-point embossing mechanism for processing paper drawing, comprising a feeding device, a processing mechanism and a discharging assembly, wherein the feeding device comprises a paper drawing roll sleeved on the rotating shaft surface of a feeding bracket, the number of the paper drawing rolls is two, and the processing mechanism is composed of an embossing assembly, a cutting assembly and a folding assembly; the embossing assembly is composed of embossing rollers, the number of the embossing rollers is two groups, and two of each group are arranged up and down, the surface of the embossing roller is provided with a four-side embossing pattern formed by raised embossing convex points, and the surface of the embossing roller is in contact with a brush roller for removing paper scraps from the surface of the embossing roller; the cutting assembly is composed of a flying knife roller and a bottom knife roller, the surface of the flying knife roller is equipped with an air hole cutting knife, the surface of the bottom knife roller is provided with a plurality of cutting grooves equipped with air hole bottom knives and a plurality of negative pressure holes for generating negative pressure adsorption force to adsorb paper drawing, and the interior of the bottom knife roller is also provided with a negative pressure cavity connected with the negative pressure hole; the folding assembly is composed of a folding roller, the number of the folding rollers is two, and the folding roller one and the folding roller two rotate in opposite directions.

[0007] The discharging assembly comprises a discharging arc plate arranged below the folding roller to form a discharging channel, and the discharging arc plate extends to the outside of the machine body for easy connection with the packaging equipment.

[0008] Preferably, the feeding device further comprises a paper guide roller arranged between the processing device and the feeding bracket and a complex roller for stretching the paper.

[0009] Preferably, the paper of the paper drawing roll 1 is conveyed between the embossing roller 1 and the embossing roller 2 through the paper guide roller and the reshaping roller.

[0010] Preferably, the paper of the paper drawing roll 2 is conveyed to between the embossing roller 3 and the embossing roller 4 through the paper guide roller.

[0011] Preferably, the rotation speeds of the embossing roller, the reshaping roller, the paper guide roller, the paper withdrawal roll and the bottom knife roller are all matched.

[0012] Preferably, negative pressure air chambers in contact with the negative pressure cavity are provided at both ends of the bottom knife roller, and the negative pressure air chambers can be connected to different negative pressure cavities when the bottom knife roller rotates, and the negative pressure air chambers are connected to the negative pressure air pump.

[0013] The present invention has the following beneficial effects:

[0014] 1. The four-side point-to-point embossing mechanism for paper-pulling processing proposed in the present invention adopts a feeding bracket to assist in feeding, and at the same time adopts a paper guide roller to limit the direction of the paper-pulling, and adopts a complex roller to stretch the paper to improve the quality of paper feeding. The upper and lower embossing rollers in the two groups of embossing rollers adopt point-to-point pressing to produce flower shapes, and the paper-pulling is located in the middle to form a four-side embossed flower pattern, so that the paper-pulling paper has grooves on both sides, and will not cause single-sided protrusions. The surface of the paper-pulling is smoother and flatter, which improves the touch of the paper-pulling with the skin when in use, and at the same time enhances the integrity of a single piece of paper.

[0015] 2. The four-sided point-to-point embossing mechanism for paper processing proposed by the present invention adopts an embossing roller with a four-sided flower shape to press the four-sided flower shape, and adopts a flying knife roller and a bottom knife roller to cooperate to achieve the cutting effect. At the same time, the cutting component is located below the embossing component to shorten the distance between the two, which is convenient for adjusting the cutting point and preventing the cutting point from being offset over a long distance due to the softness of the paper itself, thereby cutting out four-sided embossed paper with beautiful flower shapes.
