Description

Technical Field

[0001] The utility model relates to paper towel processing equipment, in particular to a device for staggered embossing of paper handkerchiefs. Background Art

[0002] At present, there are three mainstream embossing methods in the embossing process of paper handkerchiefs: the first is to use an embossing roller with raised embossing points and a smooth roller to emboss together. This method can only emboss a pattern on one side of the paper handkerchief, and the embossed back pattern is not beautiful. In addition, due to the uneven force on both sides of the paper towel, the embossed paper handkerchief is easy to deform at the embossing position and cause unevenness; the second is to use two embossing rollers with the same position of concave and convex inlaid composite embossing for embossing. This method can only emboss a pattern with one side raised and the other side sunken on both sides of the paper towel, and the embossed position feels rough and uneven when touched. The third is to use two embossing rollers with the same position and the same size of raised embossing points for embossing. Although this method feels better than the first two methods and is relatively more beautiful, it is difficult to align the raised embossing points of the two embossing rollers, the allowable machining error is too small, and the life of the embossing rollers is more than twice shorter than the first two. The scrap rate is high in actual production, resulting in higher production costs. Summary of the invention

[0003] The main purpose of the utility model is to provide a device for staggered embossing of paper handkerchiefs, which aims to provide a device for staggered embossing of paper handkerchiefs by arranging staggered and one-to-one convex embossing points, line segments and convex platforms on the embossing surface roller and the bottom roller, so as to produce a good interlayer combination so that each layer of paper towels is not easy to separate, and produce beautiful staggered embossing, while keeping the paper surface flat and not deformed, and the embossed position is comfortable to touch. In addition, the difficulty of adjusting the relative position of the embossing in production is reduced, the precision requirements of mechanical processing are lower, the service life of the embossing roller is extended, the production yield is higher, the cost is lower, and it is more conducive to the promotion and use of various production enterprises.

[0004] The utility model provides a device for staggered embossing of paper handkerchiefs, comprising a frame and a surface roller and a bottom roller mounted on the frame, wherein the surface roller and the bottom roller are provided with raised embossing points, line segments and raised support platforms of the surface roller, and raised embossing points, line segments and raised support platforms of the bottom roller, and characterized in that the raised embossing points and line segments of the surface roller are aligned one by one with the raised support platforms of the bottom roller, the raised embossing points and line segments of the bottom roller are aligned one by one with the raised support platforms of the surface roller, and the top surfaces of the embossing points and line segments and the top surfaces of the support platforms are on almost the same arc surfaces on the surface roller and the bottom roller, and the surface roller and the bottom roller are aligned through the surface roller and the bottom roller. Synchronous gear transmission, when embossing a paper handkerchief, the surface roller and the bottom roller rotate towards each other, and the raised embossing points and line segments of the surface roller and the raised pedestals of the aligned bottom roller, as well as the raised embossing points and line segments of the bottom roller and the raised pedestals of the aligned surface roller emboss the two surfaces of the paper handkerchief at the same time; a bottom roller synchronous gear with a waist-shaped hole for adjusting the relative position of the embossing and the surface roller is installed on the bottom roller. When the embossing positions of the surface roller and the bottom roller are not aligned, the relative position of the bottom roller synchronous gear and the bottom roller can be adjusted to align the raised embossing points and line segments of the surface roller and the bottom roller with the raised pedestals.

[0005] Preferably, the height range of the raised embossing points, line segments and the raised platforms of the surface roller and the bottom roller is 0.1mm to 0.8mm, the diameter range of the raised embossing points is 0.2mm to 0.8mm, the width range of the raised embossing line segments is 0.15mm to 0.8mm, and the length range is 0.5mm to 10mm, the width range of the raised platforms is 0.5mm to 3mm, and the length range is 1mm to 11mm.

[0006] Preferably, the surfaces of the surface roller and the bottom roller are provided with an annular protective belt around the roller surface at both ends of the roller, which is level with or 0.01mm to 0.1mm higher than the top surface of the raised embossing points, line segments and raised platforms, and the width of the annular protective belt ranges from 10mm to 50mm.

[0007] The beneficial effects of the paper handkerchief interlaced embossing device of the utility model are:

[0008] The raised embossing points and line segments of the surface roller and the raised pedestals of the bottom roller are aligned one by one, and the raised embossing points and line segments of the bottom roller and the raised pedestals of the surface roller are aligned one by one, and the top surfaces of the embossing points and line segments and the top surfaces of the pedestals are on almost the same arc surfaces on the surface roller and the bottom roller. The raised embossing points and line segments of the surface roller and the bottom roller and the raised pedestals are arranged alternately, so that different positions of the two surfaces of the paper handkerchief are simultaneously squeezed in an alternate manner, which can produce a good interlayer bonding and good adhesion between the layers, making it difficult for each layer of paper handkerchief to separate, thereby improving the flatness of the embossed surface of the paper towel. The embossing effect of the embossed patterns of the staggered surface roller and the bottom roller is beautiful. At the same time, the paper surface is not damaged or stretched during the embossing process, so that the tensile strength of the embossed paper handkerchief is not significantly reduced and it is not easy to be torn.

[0009] The surface roller and the bottom roller of the utility model are driven by synchronous gears, which can ensure that the rotational speeds of the two embossing rollers are completely consistent. Even when the running speed of the production line changes, the rotational speeds of the surface roller and the bottom roller will also change with the running speed, and no speed difference will occur, causing the paper handkerchief to be torn or the paper surface to be crushed, thereby improving the manufacturing quality of the paper towel, and the embossing feels delicate and not rough, and does not hurt the skin when wiping.

[0010] The top surface dimensions of the raised embossing points and line segments that are set on the surface roller and the bottom roller and are arranged one by one in an alternating manner are smaller than the width and length dimensions of the raised base, which allows a certain range of installation and manufacturing deviations. When the equipment is installed and operated, the difficulty of adjusting the relative position of the surface roller and the bottom roller and the difficulty of production and manufacturing are greatly reduced, the embossing quality is more stable, the service life of the surface roller and the bottom roller is longer, and the production cost is lower.

[0011] A bottom roller synchronous gear with a waist-shaped hole is installed on the bottom roller to adjust the relative position of the embossing and the surface roller. When the embossing positions of the surface roller and the bottom roller are not aligned, the raised embossing points and line segments of the surface roller and the bottom roller can be aligned with the raised base position by adjusting the relative position of the bottom roller synchronous gear and the bottom roller to ensure the embossing quality.

[0012] The surfaces of the surface roller and the bottom roller are provided with an annular protective belt at both ends of the roller, which is flush with or 0.01mm to 0.1mm higher than the top surface of the raised embossing points, line segments and raised pedestals and surrounds the roller surface. When the embossing roller is installed, used and adjusted, it can effectively protect the raised embossing points, line segments and raised pedestals on the embossing roller to prevent accidental damage to the embossing roller.

[0019] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] Reference Figure 1 , an embodiment of the staggered embossing device for paper handkerchiefs of the utility model is proposed, the paper handkerchief embossing device comprises a frame, a pair of embossing roller groups mounted on the frame, a surface roller synchronous gear 11 and a bottom roller synchronous gear 12, and a servo motor for driving the embossing roller group, the embossing roller group is composed of a surface roller 1 and a bottom roller 2, and a certain gap is left between the surface roller 1 and the bottom roller 2 for the paper to be embossed to pass through. During embossing, the driving servo motor of the embossing roller group adjusts the rotation speed of the embossing roller group according to the production line speed to maintain the tension of the embossed paper. The surface roller 1 and the bottom roller 2 are provided with surface roller raised embossing points, line segments 4 and surface roller raised support 3, and bottom roller raised embossing points, line segments 6 and bottom roller raised support 5. The surface roller raised embossing points and line segments 4 arranged on the surface roller 1 and the bottom roller 2 are aligned one by one with the raised support 5 of the bottom roller, and the raised embossing points and line segments 6 of the bottom roller are aligned one by one with the raised support 3 of the surface roller. When the paper passes through the gap between the surface roller 1 and the bottom roller 2, different positions of the two surfaces of the paper handkerchief are simultaneously squeezed in a staggered manner, which can produce a good interlayer bonding. The adhesion between the layers is good, so that the layers of paper handkerchiefs are not easy to separate, and the flatness of the embossed surface of the paper towel is improved. The embossing effect of the staggered surface roller and bottom roller embossing pattern is beautiful. At the same time, the paper surface is not damaged or stretched during the embossing process, so that the tensile strength of the embossed paper handkerchief is not significantly reduced and it is not easy to be torn.

[0021] In this embodiment, the height of the raised embossed points, line segments 4 and raised platforms 3 of the surface roller and the raised embossed points, line segments 6 and raised platforms 5 of the bottom roller is 0.3 mm. In other embodiments, the height of the raised embossed points, line segments 4 and raised platforms 3 of the surface roller and the raised embossed points, line segments 6 and raised platforms 5 of the bottom roller can be between 0.1 mm and 0.8 mm, and the appropriate value can be selected according to the specific situation. Among the raised embossed points, line segments 4 of the surface roller and the raised embossed points and line segments 6 of the bottom roller, the diameter of the raised embossed points ranges from 0.2 mm to 0.8 mm, the width of the raised embossed line segments ranges from 0.15 mm to 0.8 mm, and the length ranges from 0.5 mm to 10 mm. Among the raised platforms 3 of the surface roller and the raised platforms 5 of the bottom roller, the width of the raised platforms ranges from 0.5 mm to 3 mm, and the length ranges from 1 mm to 11 mm. Since the top surface dimensions of the raised embossing points and line segments on the surface roller 1 and the bottom roller 2 are smaller than the width and length dimensions of the raised base, a certain range of installation and manufacturing deviations can be allowed. When the equipment is installed and operated, the difficulty of adjusting the relative positions of the surface roller and the bottom roller and the difficulty of production and manufacturing are greatly reduced, the embossing quality is more stable, the service life of the surface roller and the bottom roller is longer, and the production cost is lower.

[0022] A bottom roller synchronous gear 10 with a waist-shaped hole for adjusting the relative position of the embossing and the surface roller is installed on the bottom roller 2. When the raised embossing points and line segments of the surface roller and the bottom roller are not aligned with the embossing position of the raised platform, the fixing bolts of the waist-shaped hole 8 on the bottom roller synchronous gear 10 can be loosened, the relative position of the bottom roller synchronous gear 10 and the bottom roller 2 can be calibrated, and then the fixing bolts can be retightened to align the raised embossing points and line segments of the surface roller and the bottom roller with the raised platform position to ensure the embossing quality.

[0023] At the positions near the two ends of the circumferential surfaces of the surface roller 1 and the bottom roller 2, an annular protective belt 11 is provided around the roller surface, which is level with or 0.01mm to 0.1mm higher than the top surface of the raised embossing points, line segments and raised abutments. When the embossing roller is installed, used and adjusted, it can effectively protect the raised embossing points, line segments and raised abutments on the embossing roller to prevent accidental damage to the embossing roller. In this embodiment, the width of the annular protective belt 11 is 30mm, and in other embodiments, the width range of 10mm to 50mm can be selected according to the situation.

[0024] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
