Description

Technical Field

[0001] This invention relates to the field of tissue paper production technology, and in particular to a production method for positioning embossing and fixed-length cutting of tissue paper. Background Technology

[0002] As a daily consumer product, the production efficiency and product quality of tissue paper directly affect user experience and corporate profits.

[0003] Before feeding multi-layered paper products into the paper-cutting device, the paper products and the paper-cutting device need to be positioned for feeding. In traditional tissue paper production methods, this positioning relies solely on operator estimation or measurement using tools such as rulers, resulting in a slow feeding speed. Furthermore, in existing tissue paper production, the paper-cutting device cannot easily and efficiently adjust the cutting size. When the finished product size needs to be adjusted, it takes a long time to debug the equipment, reducing production efficiency. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as difficulties in material feeding and positioning, and the difficulty in quickly adjusting the cutting size, by proposing a production method for positioning embossing and fixed-length cutting in tissue paper production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design a production method for positioning embossing and fixed-length cutting in tissue paper production, including the following steps:

[0007] S1. Preparation Phase:

[0008] Prepare paper materials, determine the number of layers N of the finished paper, and prepare N×2 quantities of single-layer paper materials.

[0009] Prepare the equipment, including two sets of paper positioning and embossing devices and one set of paper length cutting device.

[0010] S2, Positioning Embossing Stage:

[0011] N quantities of paper materials are fed into a paper positioning and embossing device. The paper positioning and embossing device combines and embosses the N quantities of paper materials to form a set of finished paper. Two sets of paper positioning and embossing devices operate synchronously to achieve synchronous output of two sets of finished paper. The two sets of paper positioning and embossing devices 1 are stacked on top of each other.

[0012] S3, Fixed-length cutting stage:

[0013] Two sets of finished paper are fed into a paper-cutting device at the same time. The two sets of finished paper are cut alternately by the paper-cutting device to achieve the effect of staggered stacking.

[0014] Preferably, the paper positioning embossing device includes a pair of embossing rollers and multiple pairs of diverting rollers, and the number of pairs of diverting rollers should be the same as the number of layers N of the finished paper.

[0015] Preferably, the spacing between multiple pairs of split rollers is adjustable so that multiple split rollers can be distributed in a mirror image with the embossing roller as the central axis.

[0016] Preferably, the paper length cutting device includes a pair of blade rollers and a pair of suction rollers. The suction rollers rotate along their own central axis and pull the finished paper output by the paper positioning and embossing device. The blade rollers rotate along their own central axis and cut the finished paper whenever the cutting blade on the blade rollers comes into contact with the finished paper on the suction rollers.

[0017] Preferably, the outer wall of the diverting roller is provided with embossing grooves, which are continuously opened along the transverse and longitudinal directions of the diverting roller.

[0018] Preferably, the cutter roller is equipped with multiple sets of cutting blades, and the cutter roller is controlled by a servo motor, which can change the rotation speed of the cutter roller to change the cutting interval.

[0019] Preferably, the distance between the knife roller and the adsorption roller is adjustable to accommodate finished paper with different layers.

[0020] Preferably, a tension control device is also provided between the paper positioning and embossing device and the paper length cutting device. The tension of the finished paper is adjusted by the tension control device, and the stability of the paper conveying is ensured.

[0021] The present invention proposes a production method for positioning embossing and fixed-length cutting in tissue paper production, which has the following advantages:

[0022] The embossing roller has embossing grooves continuously opened on its surface. The embossing grooves are used to emboss the paper surface. The embossing is a closed structure on all four sides, which helps to position the finished paper before it is fed into the paper length cutting device, thus improving the feeding efficiency. The embossing also enhances the appearance of the product.

[0023] The system uses an adsorption roller and a cutting roller. The adsorption roller pulls the finished paper, while the cutting blades on the cutting roller cut the paper. When the speed of the adsorption roller is constant, the speed of the cutting roller is changed, which alters the tangential interval between the cutting blades and the adsorption roller. The shorter the tangential interval, the smaller the size of the finished paper. This allows for rapid adjustment of the cutting size and improves production efficiency. Attached Figure Description

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] Example 1

[0033] Reference Figure 1 A production method for positioning embossing and fixed-length cutting in tissue paper production includes the following steps:

[0034] S1. Preparation Phase:

[0035] Prepare paper materials, determine the number of layers N of the finished paper, and prepare N×2 quantities of single-layer paper materials.

[0036] Prepare the equipment, including two sets of paper positioning and embossing devices 1 and one set of paper length cutting device 4.

[0037] S2, Positioning Embossing Stage:

[0038] N quantities of paper materials are fed into a paper positioning and embossing device 1. The paper positioning and embossing device 1 combines and embosses the N quantities of paper materials to form a set of finished paper. Two sets of paper positioning and embossing devices 1 operate synchronously to achieve synchronous output of two sets of finished paper. The two sets of paper positioning and embossing devices 1 are stacked on top of each other.

[0039] S3, Fixed-length cutting stage:

[0040] The two groups of finished paper are fed into the paper length cutting device 4 at the same time. The paper length cutting device 4 cuts the two groups of finished paper alternately to achieve the effect of staggered stacking.

[0041] Furthermore, a tension control device is also provided between the paper positioning and embossing device 1 and the paper length cutting device 4. The tension of the finished paper is adjusted by the tension control device, and the stability of the paper conveying is ensured.

[0042] Example 2

[0043] Reference Figure 2 The paper positioning embossing device 1 includes a pair of embossing rollers 2 and multiple pairs of diverting rollers 3. The number of pairs of diverting rollers 3 should be the same as the number of layers N of the finished paper. The spacing between the multiple pairs of diverting rollers 3 is adjustable so that the multiple diverting rollers 3 can be distributed in a mirror image with the embossing roller 2 as the central axis. (Refer to...) Figure 4 , Figure 6 The outer wall of the diverting roller 3 is provided with embossing grooves 7, which are continuously opened along the transverse and longitudinal directions of the diverting roller 3.

[0044] Working principle:

[0045] By adjusting the relative position between the diverting roller 3 and the embossing roller 2, the horizontal angle between the single-layer paper material output by the diverting roller 3 and the embossing roller 2 is less than 35°, thus avoiding the difficulty in effectively pressing the multi-layer paper material together due to excessive angle; and the number of diverting rollers 3 can be increased or decreased according to the actual number of layers to improve the versatility of the device.

[0046] Reference Figure 4 , Figure 5 , Figure 6 By opening continuous embossing grooves 7 on the surface of the embossing roller 2, and the embossing grooves 7 having a closed structure, the shape of the embossing grooves 7 can be used to position the cutting part of the paper product. The embossing grooves 7 can also enhance the aesthetics by pressing the surface of the paper product to form texture. The closed structure of the embossing grooves 7 can also prevent the edges of multi-layer paper products from delaminating, thus improving the pressing effect of the finished product.

[0047] Example 3

[0048] Reference Figure 3 The paper length cutting device 4 includes a pair of blade rollers 5 and a pair of suction rollers 6. The suction rollers 6 rotate along their own central axis and pull the finished paper output by the paper positioning and embossing device 1. The blade rollers 5 rotate along their own central axis, and cut the finished paper whenever the cutting blade on the blade roller 5 comes into contact with the finished paper on the suction roller 6. The blade roller 5 is equipped with multiple sets of cutting blades. The blade roller 5 is controlled by a servo motor, which can change the speed of the blade roller 5 to change the cutting interval. The distance between the blade roller 5 and the suction roller 6 is adjustable to accommodate finished paper with different layers.

[0049] Working principle:

[0050] When the rotation speed of the adsorption roller 6 is constant, the rotation speed of the cutter roller 5 is changed, which changes the tangential interval between the cutting blade on the cutter roller 5 and the adsorption roller 6. The shorter the tangential interval between the cutting blade and the adsorption roller 6, the smaller the size of the finished paper; the longer the tangential interval between the cutting blade and the adsorption roller 6, the larger the size of the finished paper.

[0051] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
