Description

Technical Field

[0001] The utility model relates to the field of embossing of sanitary products, in particular to a embossing production line for sanitary products. Background Art

[0002] Sanitary products include diapers, pull-up pants, sanitary napkins, and sleeping pants, etc. Sanitary products include a surface layer, a core layer, and a bottom layer, wherein the surface layer is provided with a pattern, which is a pattern composed of convex areas and concave areas (the pattern is realized by embossing technology). By setting the pattern, the aesthetics of the surface of the sanitary product can be improved, and the setting of the pattern can also increase the infiltration and absorption speed of the sanitary product for the excreted liquid (for example, the quick-absorption anti-reverse osmosis structure, fabric, and sanitary product disclosed in Chinese patent announcement number CN219070988U).

[0003] The pattern of the surface layer of current sanitary products is pressed out by an embossing roller on the production line. As the fabric is continuously conveyed, the embossing roller presses out multiple patterns arranged horizontally on the fabric, and the multiple patterns are completely consistent. Then, after the fabric, core layer and bottom layer are compounded, they are cut between the two patterns to form multiple separate products, so that the pattern on each product is consistent.

[0004] Therefore, when sanitary products are worn on the body, since the pattern of each product is consistent, even if consumers frequently change sanitary products, the relative positions of the embossed concave and convex points on the sanitary products will not change. No matter how the sanitary products are changed, the local area of ​​the consumer's skin will be continuously contacted by the convex points at the same position on the sanitary products for a long time, thereby pressing corresponding marks on the local area of ​​the consumer's skin. At the same time, the long-term contact between the convex points and the skin will cause the skin to have an allergic stress reaction due to the long-term blockage of the sweat gland pores and the long-term exposure to external substances, thereby causing skin discomfort. Utility Model Content

[0005] The utility model aims to provide a sanitary product pattern production line to solve the problem that consumers' skin is contacted and squeezed by the same pattern on the sanitary products for a long time.

[0006] To achieve the above purpose, the utility model adopts the following technical solution: a sanitary product pattern production line can continuously produce sanitary products with at least two different patterns. Continuously producing sanitary products with at least two different patterns means that sanitary products with different patterns are continuously arranged after production, and there are at least two different patterns.

[0007] The patterns of products in the prior art are processed on the production line, and the working principles of the production lines on the market are all the same: the pattern is pressed out by the embossing roller, and the embossing roller rotates one circle to press out the corresponding pattern on the fabric. In this way, the patterns pressed out on different products are the same, which leads to the problems in the background technology. When faced with the technical problem of more serious indentations on the skin, the technicians in this field usually reduce the elasticity of the sanitary products or increase the softness of the fabric of the sanitary products to reduce the squeezing of the skin. Although the above-mentioned means can alleviate the problem, the skin will still be squeezed by the convex points of the same flower pattern for a long time, and over time, there will still be certain indentations.

[0008] The inventor of the present application discovered the technical problem and improved the production line, enabling the production line to continuously produce sanitary products with at least two different patterns. In this way, different products produced can have different types of patterns, which can solve the technical problem of the present application. For this reason, the applicant will apply for a patent for a pattern production line that can continuously produce sanitary products with at least two different patterns for protection.

[0009] Preferably, as an improvement, at least two sanitary products with different patterns are embossed by a set of embossing rollers.

[0010] After research and development, the inventor found that different types of patterns can be embossed on the fabric by using one group of embossing rollers or multiple groups of embossing rollers. However, compared with the prior art, using multiple groups of embossing rollers to emboss separately will increase the number of embossing rollers, and the embossing rollers will occupy a larger space, which will cause greater changes to the production line, making the operation more troublesome and increasing the cost. Therefore, the present scheme preferably uses one group of embossing rollers to emboss the pattern, which will cause less changes to the production line and reduce the cost.

[0011] Preferably, as an improvement, it includes an embossing roller, a plurality of pattern areas are circumferentially distributed on the circumferential surface of the embossing roller, each pattern area is provided with a pattern, a single pattern area is used for rolling a pattern on a single product, and there are at least two pattern areas.

[0012] The embossing roller in the prior art is only provided with one pattern area, so that when the fabric passes through the embossing roller, the embossing roller presses out a plurality of sequentially arranged patterns on the fabric, and the plurality of sequentially arranged patterns are all consistent, resulting in the consistent pattern of the prepared sanitary products. When consumers use sanitary products, their skin will be squeezed by the raised points of the same pattern, resulting in more serious indentations, thus causing the problems in the background technology.

[0013] In the present solution, the inventor, through analysis, sets multiple pattern areas on a group of embossing rollers, and there are at least two pattern areas on the embossing roller. In this way, after the fabric passes through the embossing roller, the embossing roller presses out multiple patterns on the fabric. However, since there are multiple pattern areas, there are multiple patterns on the fabric, and the patterns on the fabric will not be completely consistent, which ensures that the patterns on multiple separate products produced subsequently will not be completely consistent. When consumers replace sanitary products during the use of sanitary products, they will use products with different patterns (different patterns, and basically different convex points). The skin will not be squeezed and contacted by the convex points of the same pattern for a long time, which can enable the consumer's skin to recover in stages, which is conducive to improving comfort and reducing the occurrence of indentations.

[0014] At the same time, during the production process, different care mineral and plant essences can be controlled on sanitary products according to different patterns, thereby reducing skin resistance and improving health care capabilities.

[0015] Preferably, as an improvement, a blank area is provided between adjacent pattern areas.

[0016] The function of the blank area is that when the fabric passes through the embossing roller, the blank area will not emboss a pattern on the fabric, so that there is a blank area between adjacent patterns on the fabric. When the fabric, core layer and bottom layer are compounded, the blank area is the part that is cut by the slitting roller.

[0017] Preferably, as an improvement, the number of pattern areas is 2-5.

[0018] Since each pattern area is used to roll a pattern on a product, the arc length of each pattern area is fixed. Therefore, when the number of pattern areas increases, the circumference of the embossing roller will increase, resulting in a larger diameter of the embossing roller. However, due to the space limitations of the processing production line, the diameter of the embossing roller cannot be infinitely increased. Therefore, 2-5 types of patterns are more appropriate. At this time, the diameter of the embossing roller is more appropriate and will not be too large, and it can also meet the different requirements of different product patterns.

[0019] Preferably, as an improvement, the pattern shapes, pattern sizes or pattern positions of the two pattern areas are different.

[0020] In the present application, different types of patterned areas refer to different patterns in shape, size or position, but are not limited thereto. Any patterned area that changes the contact and extrusion conditions of the pattern pressed out by the patterned area on the fabric can be considered as a different type of patterned area. For example, if the patterned shapes of the patterned area are different, the corresponding pressed pattern shapes will be different. Since the convex points are the components of the pattern, the position, arrangement and shape of the convex points of the pattern will change, thereby changing the contact and extrusion conditions on the skin; for another example, if the pattern sizes of the patterned area are different, the size of the pattern pressed out by the pattern will be different. In this way, although the shape of the pattern is the same, the convex points of the pattern can also change due to the different sizes of the pattern, thereby changing the contact and extrusion conditions on the skin; for another example, if the pattern positions on the patterned area are different, although the pressed pattern shapes are the same, the positions of the convex points inside the pattern will also change, thereby achieving contact with different parts of the skin and avoiding the same part of the skin from being squeezed for a long time.

[0021] Preferably, as an improvement, the diameter of the embossing roller is 25.4-28.6 cm.

[0022] When multiple pattern areas are set on the embossing roller, the diameter of the embossing roller will become larger. However, due to the space limitation of the production line, the diameter of the embossing roller cannot be infinitely increased. Therefore, it is more appropriate to set the diameter of the embossing roller to this size, which will not take up a large space and can also meet the needs of production and manufacturing.

[0023] Preferably, as an improvement, at least two sanitary products with different patterns are embossed by multiple groups of embossing rollers. Although the embossing rollers can be set as one group, and multiple pattern areas are set on the embossing rollers, so as to solve the technical problem, it is not excluded to set multiple groups of embossing rollers, and when the fabric passes through different groups of embossing rollers, different groups of embossing rollers emboss different types of patterns on the fabric.

[0024] Preferably, as an improvement, it further comprises a slitting unit, which comprises a slitting roller; a tensioning unit is provided between the slitting unit and the embossing roller, which comprises a plurality of tensioning rollers.

[0025] The tensioning roller of the tensioning unit in this solution is used to tension the fabric, so that the fabric is in a tensioned state to ensure that the fabric can be smoothly transmitted. When the fabric, the core layer and the bottom layer are compounded to form a composite body, the slitting roller on the slitting unit rotates to cut the composite body compounded with the fabric into multiple products.

[0026] Preferably, as an improvement, it also includes:

[0027] A pattern detection unit, the pattern detection unit includes a camera, the camera is located between the embossing roller and the slitting roller, and detects the pattern on the fabric;

[0028] A slitting detection unit, used to detect the rotation and slitting conditions of the slitting roller;

[0029] The control unit is used to analyze the information collected by the pattern detection unit and the information detected by the slitting detection unit, determine whether the pattern movement and slitting are synchronized, and adjust the movement speed of the fabric.

[0030] Therefore, after the fabric passes through the embossing roller, the embossing roller embosses a pattern on the fabric, and then the fabric passes through the pattern detection unit. The camera records and photographs the pattern passing through the fabric, and transmits the detection information to the control unit. The control unit obtains the time period T1 taken by a pattern passing through the camera through analysis, and obtains the timing diagram ( Figure 7 or Figure 8 The slitting detection unit is used to detect the rotation and slitting of the slitting roller and transmit the detected information to the control unit. The control unit obtains the slitting cycle T2 of the slitting roller through analysis and obtains the timing diagram through continuous detection ( Figure 7 or Figure 8 The control unit then compares M with N. When M and N coincide, it indicates that the moving speed of the fabric matches the rotating speed of the slitting roller, and there will be no deviation when the slitting roller is slitting. At this time, there is no need to adjust the moving speed of the fabric. When the M signal lags behind the N signal in one cycle, it indicates that there is a problem of slitting ahead of time, and the fabric movement is in a lagging state. It is necessary to control the fabric and the composite body to accelerate the operation of the servo motor and other control systems, so that the M and N signals are consistent in one cycle to ensure the position accuracy of the slitting of the slitting roller. Similarly, in one cycle, the M signal leads the N signal, which indicates that there is a phenomenon of slitting lag. It is necessary to slow down the servo motor and other control systems to compensate, so that the moving speed of the fabric and the composite body is reduced, so that the M and N signals are consistent in one cycle, and the position accuracy of the slitting of the slitting roller is ensured. Therefore, through this scheme, it is ensured that the slitting roller can slitting in the blank area between two adjacent patterns, avoiding the slitting roller from cutting on the pattern and destroying the pattern when slitting.

[0031] Preferably, as an improvement, the pattern detection unit further includes two guide rollers, and the camera is located between the two guide rollers. Thus, the setting of the guide rollers can change the transmission direction of the fabric, so that the fabric can be transmitted toward the camera, and after the camera detection is completed, it can be transmitted toward the slitting roller.

[0032] Preferably, as an improvement, the slitting unit further comprises a composite roller, which is located before the slitting roller. Thus, the composite roller is arranged to composite the fabric, the core layer and the bottom layer together.

[0033] Preferably, as an improvement, the pattern detection unit further includes a light source. The provision of the light source can increase the brightness, making the camera's photos and videos clearer. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The following is further described in detail through specific implementation methods:

[0047] The figure marks in the drawings of the specification include: upper embossing roller 1, lower embossing roller 2, tensioning roller 3, slitting roller 4, product 5, composite body 6, fabric 7, pattern area 8, blank area 9, first pattern area 10, second pattern area 11, first pattern 13, second pattern 14, blank area 15, embossing sheet 16, groove 17, screw 18, protrusion 19, camera 20, composite roller 21, first guide roller 22, and second guide roller 23.

[0048] Example 1

[0049] Basically as attached Figure 1-Figure 4 As shown: a sanitary product pattern production line, including an embossing unit, a tensioning unit and a slitting unit. In this embodiment, the slitting unit includes a slitting roller 4 and a composite roller 21. The composite roller 21 is located in front of the slitting roller 4. The slitting roller 4 is fixed with a slitting knife by screws; the tensioning unit is located between the slitting unit and the embossing unit, and the tensioning unit includes a plurality of tensioning rollers 3. The embossing unit in this embodiment includes an embossing roller, which is specifically divided into an upper embossing roller 1 and a lower embossing roller 2. Through the cooperation of the upper embossing roller 1 and the lower embossing roller 2 (the upper embossing roller 1 and the lower embossing roller 2 are both provided with patterns, and the patterns on the two embossing rollers are convex patterns and concave patterns respectively), when the fabric 7 passes through the upper embossing roller 1 and the lower embossing roller 2, the upper embossing roller 1 and the lower embossing roller 2 squeeze the fabric 7, thereby pressing out a pattern on the fabric 7. The rotation power of the embossing roller, the tensioning roller 3 and the composite roller 21 in this embodiment is driven by a servo motor.

[0050] This embodiment mainly improves the embossing roller in the production line. The upper embossing roller 1 and the lower embossing roller in the prior art are both provided with a pattern area 8 ( Figure 2 The bold part, the pattern area 8 is provided with a pattern for embossing a pattern) and the blank area 9 ( Figure 2 When the fabric 7 passes between the upper embossing roller 1 and the lower mixing roller, the upper embossing roller 1 and the lower embossing roller 2 squeeze the fabric 7, thereby pressing out a plurality of identical patterns on the fabric 7, and the plurality of identical patterns are arranged in sequence on the fabric 7. The patterned fabric 7 passes through the tensioning unit and is compounded with the composite 6 (the core layer and the bottom layer are compounded together in advance) (the fabric 7 forms the surface layer of the sanitary product), and the composite 6 with the fabric continues to be conveyed to the right and passes through the slitting unit. The slitting roller 4 cuts the transferred composite 6 in the blank area between adjacent patterns (the blank area is the area where the fabric 7 is squeezed by the blank area 9), thereby forming a plurality of products 5. At this time, the patterns of the plurality of products 5 produced are all consistent.

[0051] In this embodiment, the upper embossing roller 1 and the lower embossing roller 2 are improved, the diameters of the upper embossing roller 1 and the lower embossing roller 2 are enlarged (the diameter is 25.4-28.6 cm), and the Figure 3As shown, multiple pattern areas and multiple blank areas 9 are provided on both the upper embossing roller 1 and the lower embossing roller 2. One pattern area is used to roll a pattern on a product, and multiple pattern areas are distributed along the circumference of the embossing roller. In this embodiment, two pattern areas are described as an example. The upper embossing roller 1 and the lower embossing roller 2 are respectively provided with a first pattern area 10 and a second pattern area 11. There are two blank areas 9, and the two blank areas 9 are respectively located between the end of the first pattern area 10 and the end of the second pattern area 11. The first pattern area 10 is used to extrude a first pattern 13, and the second pattern area 11 is used to extrude a second pattern 14. The pattern type on the first pattern area is different from the pattern type on the second pattern area. In this way, the combination Figure 4 As shown, when the fabric 7 passes through the upper embossing roller 1 and the lower embossing roller 2, the first pattern 13 and the second pattern 14 are simultaneously embossed on the fabric 7, and the first pattern 13 and the second pattern 14 are alternately distributed, and there is a blank area 15 between the first pattern 13 and the second pattern 14 that is not squeezed by the pattern. After the fabric 7 is compounded on the composite body 6, the composite body containing the fabric 7 continues to be conveyed to the right, and the slitting roller 4 cuts the composite body 6 in the blank area 15 between the first pattern 13 and the second pattern 14, thereby forming a plurality of products 5, and the first pattern 13 and the second pattern 14 are provided on two adjacent products 5 cut in this way.

[0052] In this embodiment, there are two types of pattern areas on the embossing roller. Of course, in other embodiments, there may be three, four, etc. Since each pattern embossing corresponds to a product 5, the more types of patterns there are, the larger the diameter of the embossing roller is set. In order to control the diameter of the embossing roller, the types of patterns on the embossing roller are generally 2-5, preferably 2.

[0053] The criteria for distinguishing the types of pattern areas in this embodiment are: if the specific pattern size, pattern shape or pattern position in the pattern area is different, it can be evaluated as a different type of pattern area, but it is not limited to this. Any pattern area that changes the compression of the skin by the convex points of the pressed pattern by changing the pattern on the pattern area (for example, the part of the skin that is pressed by the convex points changes, or the area of ​​the skin that is pressed by the convex points changes, or the skin is pressed by different numbers of convex points, or the skin is pressed by convex points of different shapes, etc.) can be considered as a different type of pattern area. Fig.10 As shown, the pattern shapes of the pattern areas are different. The pattern of the pattern area on the left side of the figure is composed of multiple circular patterns, and the pattern of the pattern area on the right side is composed of multiple triangular patterns. Fig.10The two types of pattern areas in the figure have different convex shapes (the convex points of the pattern on the left are circular, and the convex points of the pattern on the right are triangular). The patterns are applied to the same part of the body at the same time. Due to the different shapes of the triangle and the circle (their areas are also different), the contact degree between the convex points of different shapes and the skin is different. For example, combined with Fig. 9 As shown in the figure, the patterns in the pattern area have the same shape, and the patterns are all circular, but the sizes of the patterns in the pattern area are different. The patterns in the left pattern area are larger, and the patterns in the right pattern area are smaller. The sizes of the convex points of the patterns pressed out by the patterns of different sizes are also different, so that when the patterns of different sizes come into contact with the skin, the contact area between the skin and the convex points changes, and the contact and extrusion conditions between the skin and the pattern are different at this time; for example, combined with Fig.11 As shown in the figure, the pattern shapes of the pattern areas are the same, both are circular, but the positions of the patterns have changed. Fig.11 The pattern on the left side of the pattern area is overall to the left compared to the pattern on the right side. The convex points of the patterns pressed out by the two patterns at different positions are also at different positions. When the two pressed patterns act on the same area of ​​the skin, the contact points between the skin and the convex points change. Figure 9-11 The patterns in the figure are only for illustration and explanation. In practice, the pattern shape of the pattern area can be set to any shape, regular or irregular, and the size and position can also be set arbitrarily, as long as the two extruded patterns act on the skin in the same area to change the squeezing condition of the skin.

[0054] Therefore, after the products are cut, multiple products 5 (the patterns in the multiple products 5 are not completely consistent) are put into a packaging box or packaging bag for packaging. In this way, when the consumer uses the product 5 in the packaging box or packaging bag, when the product 5 is replaced, the pattern of all the products 5 in the packaging box or packaging bag will not be exactly the same, causing the same position of the consumer's skin to always be contacted and squeezed by the same pattern. At least one product 5 in the packaging box or packaging bag has a different pattern. When the consumer uses the product 5, the pattern type changes, and the situation in which the consumer's skin is contacted and squeezed by the convex points of the pattern changes, so that the consumer's skin will not be squeezed continuously, and the previously squeezed part can be restored in stages, thereby reducing the generation of indentations and improving the comfort of the product 5.

[0055] Example 2

[0056] Combination Figure 1 As shown, the sanitary product pattern production line in this embodiment further includes a pattern detection unit, a slitting detection unit and a control unit.

[0057] The pattern detection unit includes a light source (such as an LED light source), a camera 20 (such as a CCD camera or a COMS camera), a first guide roller 22 and a second guide roller 23. The number of the first guide roller 22 and the second guide roller 23 are both two, and the first guide roller 22 and the second guide roller 23 are distributed laterally. The fabric 7 passes through the first guide roller 22 and the second guide roller 23 after passing through the tensioning unit. The camera 20 is located between the embossing roller and the slitting roller 4. More specifically, the camera 20 is located between the first guide roller 22 and the second guide roller 23, and detects the pattern on the fabric 7.

[0058] The slitting detection unit is used to detect the rotation and slitting conditions of the slitting roller 4. Specifically, the slitting detection unit can be various sensors. For example, the slitting detection unit can be a photoelectric sensor. The photoelectric sensor is installed on the frame. By detecting the changes in the slitting knife on the slitting roller 4 when it passes, the rotation speed of the slitting roller 4 and the time when the slitting knife cuts the composite 6 are determined. For another example, the slitting detection unit can also use a vibration sensor. By installing a vibration sensor, the vibration condition of the slitting roller 4 is detected. Because the slitting knife of the slitting roller 4 will generate vibration (with a specific vibration frequency and amplitude) when cutting the composite 6, the rotation speed of the slitting roller 4 and the time of slitting are determined according to the vibration condition. Of course, the specific rotation speed of the roller shaft and the time of cutting can also be monitored by installing an encoder to provide accurate rotation state information.

[0059] The control unit is used to analyze the information collected by the pattern detection unit and the information detected by the slitting detection unit, determine whether the pattern movement and slitting are synchronized, and adjust the moving speed of the fabric 7. The control unit in this embodiment can be a PLC control system. The camera 20 and the sensor in the slitting detection unit are electrically connected to the PLC control system.

[0060] Thus, after the fabric 7 passes through the embossing roller, the embossing roller embosses the first pattern 13 and the second pattern 14 on the fabric 7, and the first pattern 13 and the second pattern 14 are alternately distributed in sequence, and then the fabric 7 is transmitted between the first guide roller 22 and the second guide roller 23. The fabric 7 passes through the pattern detection unit, and the camera 20 records and photographs the pattern passing through the fabric 7, and transmits the detected information to the control unit. The control unit obtains the time period T1 (combined with the time period T2 of the time period T1 of ... Figure 4 As shown, the cycle is the time taken by the camera 20 to scan from the right side of the first pattern 13 to the right side wall of the second pattern 14, or the time taken by the camera 20 to scan from the right side of the second pattern 14 to the right side of the first pattern 13). As the fabric 7 is continuously conveyed, the control unit plots the cycle continuously measured by the camera 20 into a timing diagram ( Figure 7 or Figure 8The slitting detection unit is used to detect the rotation and slitting of the slitting roller 4, and transmit the detected information to the control unit. The control unit obtains the slitting cycle T2 of the slitting roller 4 by analysis (the cycle is the time from the composite body 6 with the fabric being transported to the right being cut by the slitting knife of the slitting roller 4 to the time when the composite body 6 is cut next time). As the slitting roller 4 rotates continuously, the control unit plots the detected signal into a timing diagram ( Figure 7 or Figure 8 N signal graph in Figure ). Combined with Figure 5-Figure 8 As shown, the control unit then compares M with N and combines Figure 6 As shown in FIG. 1 , when M and N coincide, it indicates that the moving speed of the fabric 7 matches the rotation speed of the slitting roller 4, and there will be no deviation when the slitting roller 4 is slitting (ensuring that the cutting part of the slitting roller 4 is located in the blank area 15 between the first pattern 13 and the second pattern 14). At this time, there is no need to adjust the moving speed of the fabric 7. When in one cycle, combined with Figure 7 As shown in the figure, if the M signal lags behind the N signal, it means that there is a problem of slitting ahead of time, and the movement of the fabric 7 is in a lagging state, that is, the blank area 15 of the composite body 6 has not moved to the slitting roller 4, and the slitting knife of the slitting roller 4 has performed a cutting operation. At this time, the control unit controls the servo motor to speed up the servo motor, thereby controlling the fabric 7 and the composite body 6 to accelerate, so that the M and N signals are consistent within a cycle, ensuring the position accuracy of the slitting roller 4; similarly, within a cycle, combined with Figure 8 As shown, if the M signal is ahead of the N signal, it means that the slitting lag occurs, that is, the blank area 15 of the composite body 6 has moved to the slitting roller 4, and the slitting roller 4 has not yet performed the cutting operation. At this time, the control unit needs the servo motor and other control systems to slow down and compensate, so that the moving speed of the fabric 7 and the composite body 6 is reduced, so that the M and N signals remain consistent within a cycle, ensuring the position accuracy of the slitting by the slitting roller 4. Therefore, through this solution, it is ensured that the slitting roller 4 can slitting in the blank area 15 between two adjacent patterns, avoiding the slitting roller 4 cutting on the pattern and destroying the pattern when slitting.

[0061] Example 3

[0062] Combination Fig.12As shown, the embossing roller in this embodiment includes an embossing sheet 16, a roller shaft, and a plurality of protrusions 19 integrally located on the roller shaft, with an installation space between adjacent protrusions 19, and the surface of the protrusions 19 is a blank area 9. The embossing sheet 16 is arc-shaped so that it can fit with the roller shaft, and the embossing sheet 16 is installed in the installation space between adjacent protrusions 19, and the embossing sheet 16 is detachably connected to the roller shaft. In this embodiment, there are two protrusions 19, and the two protrusions 19 are opposite to each other. The number of embossing sheets 16 is two, and the two embossing sheets 16 are respectively provided with a first pattern area 10 and a second pattern area 11.

[0063] The specific detachable connection mode of the embossing sheet 16 and the roller in this embodiment is as follows: a groove 17 is provided on the surface of the embossing sheet 16, and the groove 17 is located on the side of the edge of the first pattern area 10, so as not to affect the embossing of the fabric 7 by the pattern area 8, and the screw 18 is threadedly connected in the groove 17 and connected to the roller. The groove 17 is provided in this embodiment so that the screw 18 does not protrude from the surface of the embossing sheet 16, and when the upper embossing roller 1 and the lower embossing roller 2 cooperate with each other, it can be avoided that the screw 18 protrudes and affects the cooperative rotation of the upper embossing roller 1 and the lower embossing roller 2.

[0064] The embossed sheet 16 in this embodiment is detachable, so that the embossed sheet 16 with different patterns can be replaced according to actual conditions, thereby achieving the change of the pattern on the embossed product 5.

[0065] Example 4

[0066] The different types of patterns on the fabric in Example 1 are embossed by a group of embossing rollers. This embodiment discloses another embossing method: the different patterns on the fabric in this embodiment can be embossed by different groups of embossing rollers, and different groups of embossing rollers are provided with different patterns. In this way, when the fabric passes through different groups of embossing rollers, different groups of embossing rollers emboss different types of patterns on the fabric.

[0067] The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
