Detailed Description

The present invention will be described in further detail with reference to the following embodiments and accompanying drawings.

An embossing system for hand towel paper as shown in fig. 1-3, which adopts an upper group and a lower group to emboss the paper by facing cylinder rollers, a plurality of embossing salient points which are regularly arranged are engraved on a steel roller by adopting an engraving process, for the convenience of description, the embossing salient points on an upper press roller 1 are called as first embossing salient points 3, and the salient points on a lower press roller 2 are called as second embossing salient points 4. In order to make the paper towel embossed by the upper and lower pressing rollers have embossed spots with upper and lower surfaces protruding, in this example, the first embossing salient points 3 are arranged in a staggered manner relative to the second embossing salient points 4, that is, when the upper pressing roller 1 is combined with the lower pressing roller 2, the first embossing salient points 3 are just positioned in the gaps of the second embossing salient points 4. The first embossing salient points 3 and the second embossing salient points 4 are arranged in a rectangular array mode, the X-axis array direction of the first embossing salient points 3 and the axis direction of the upper pressing roll 1 form an alpha angle, and the value range of alpha is 10-40 or 50-80. Since the embossing direction of the lower press roll 2 to the paper towel is from bottom to top, which is opposite to the upper press roll, the X-axis array direction of the second embossing salient points 4 is symmetrical to the X-axis array direction of the first embossing salient points 3 about the joint plane.

In example 1 shown in fig. 2, in this example, the value of α is set to 15 °, the first embossed dots 3 and the second embossed dots 4 are arranged in a staggered manner, the embossed dots are circular dots, the depth of the embossed dots is 1.25mm, the pitch is 4mm, embossing with two-way convex points is realized on the toilet paper, and when a plurality of embossed toilet papers are stacked, the overlapping of concave and convex points of two adjacent toilet papers is not easy to occur, so that the foaming degree of the whole toilet paper during subpackaging is good, and the thicknesses of the paper bags are consistent.

The value of alpha in the embodiment 2 shown in figure 3 is 60 degrees, the first embossing points 3 and the second embossing points 4 are arranged in a staggered mode, the embossing points are square points, the depth of the embossing points is 1.25mm, the distance between the embossing points is 4mm, and the embossing of the toilet paper with the bidirectional convex points is realized. When a plurality of embossed tissues are stacked, the concave-convex points of two adjacent tissues are not easy to overlap, so that the overall foaming degree is good during subpackage, and the thickness of the paper bags is consistent.

After a plurality of tests, the situation that the concave-convex points coincide after a plurality of embossed toilet paper are stacked only when the value of alpha is 0-10 degrees, 40-50 degrees or 80-90 degrees is discovered, so that the integral foaming degree of the stacked and packaged paper packages is not enough, the sizes of the packages are different, and the analysis reason is that when the value of alpha is 0-90 degrees, the overlap ratio of the arrangement direction of the flower points on the toilet paper and the length direction or the width direction of the paper is high, so that the concave-convex points of two adjacent pieces of paper are completely overlapped when the edges of the two adjacent toilet paper are completely aligned during stacking, and the concave-convex points can be completely overlapped no matter the two adjacent toilet paper are staggered by one flower point distance along the length direction or the width direction, so that the probability of the coincidence of a plurality of toilet paper during stacking is greatly improved, and the foaming degree is not enough; in the same way, the same condition can also occur when the value of alpha is about 45 degrees, the concave-convex points of the two adjacent pieces of paper are completely overlapped except when the edges of the two adjacent pieces of paper towel are completely aligned in the stacking process, and the concave-convex points are completely overlapped when the diagonal distance of one flower dot array is staggered along the length direction or the width direction of the two adjacent pieces of paper towel, so that the probability of overlapping the concave-convex points of the two adjacent pieces of paper is greatly improved, and the foaming degree is not enough.

To sum up the process the utility model discloses a paper towel of paper towel knurling system extrusion only can just can appear the coincidence of concave and convex point under the condition that two adjacent paper towels align completely all around at range upon range of in-process, can know in the actual production, the condition that two adjacent paper align completely hardly appears in the range upon range of packaging process of many paper towels, consequently, the condition that the coincidence of concave and convex point can not appear as long as two adjacent paper appears the dislocation, consequently very big reduction the probability of the coincidence of concave and convex point, foaming degree is good when satisfying the paper towel and subpackaging, and the package type of paper package is unanimous when the same quantity is subpackaged.
