Description

Technical Field

[0001] This utility model relates to the field of rotary die-cutting technology, and in particular to a composite embossing roller for flexible materials. Background Technology

[0002] Common embossing stations on existing sanitary napkin production lines include: perimeter sealing embossing station; flow-guiding embossing station; three-piece sealing embossing station; and surface layer embossing station. The main function of the three-piece sealing embossing station is to press the high-value surface material in the middle together with the lower-value ordinary materials on the left and right sides to reduce material costs. The function of the surface layer embossing station is to emboss aesthetically pleasing patterns onto the high-value surface material in the middle, enhancing the product's image.

[0003] like Figure 1 As shown, the existing three-piece pressing station and surface embossing station are two separate stations. The three-piece pressing assembly 200 and the surface embossing assembly 300 are arranged one after the other. The mold manufacturing cost is high and the production line is long, requiring a large space and high energy consumption. Utility Model Content

[0004] In view of the above problems, this application provides a composite embossing roller for flexible materials to solve the technical problems of existing three-piece pressing station and surface embossing station being two separate stations, with the three-piece pressing assembly and surface embossing assembly arranged in front and behind, resulting in high mold manufacturing costs, long production lines, large space requirements, and high energy consumption.

[0005] To achieve the above objectives, the inventors provide a composite embossing roller for flexible materials, comprising:

[0006] mandrel;

[0007] The roller body is sleeved on the mandrel, and a protective step is provided at each end of the roller body;

[0008] The embossing assembly is disposed on the outer surface of the roller body and located between two protective steps. The embossing assembly includes two spaced three-piece embossed patterns and a surface embossed pattern, with the surface embossed pattern disposed between the two three-piece embossed patterns.

[0009] Unlike existing technologies, the technical solution of this application integrates the three-piece pressing station and the surface embossing station into one unit, and is equipped with a composite embossing roller. Both the three-piece pressing pattern and the surface embossing pattern are set on the outer surface of the roller body. On the one hand, this reduces mold manufacturing costs, shortens the production line length, saves production space, and saves production energy. On the other hand, since the three-piece pressing pattern and the surface embossing pattern are engraved on the same roller, their relative positions can be precisely controlled, improving the quality of flexible materials.

[0010] As an embodiment of the utility model, the height of the teeth of the surface layer embossed pattern in the vertical direction is lower than the height of the teeth of the three-piece embossed pattern in the vertical direction.

[0011] Therefore, since the fabric pressed by the three-piece embossed pattern generally has multiple layers, and the fabric pressed by the surface layer embossed pattern only has one layer, the height of the teeth of the surface layer embossed pattern in the vertical direction is lower than the height of the teeth of the three-piece embossed pattern in the vertical direction, so that the two patterns are clear at the same time when embossed.

[0012] As an embodiment of the utility model, the composite embossing roller for flexible materials further comprises a heating module, and the end surface of the roller body or the center of the mandrel is provided with a heating hole.

[0013] Therefore, the heating module is beneficial to accelerate the formation of the surface layer embossed pattern and the three-piece embossed pattern, and can also reduce the rebound amount after formation. The heating module is a heating rod.

[0014] As an embodiment of the utility model, the end surface of the roller body is provided with two or more heating holes in the circumferential direction of the mandrel, and one heating hole corresponds to one heating module.

[0015] Therefore, since the cross section of the roller body is circular, two or more heating holes are provided in the circumferential direction of the mandrel on the end surface of the roller body, or one heating hole is provided in the center of the shaft, and the heating module is installed in the heating hole, so as to enhance the heating effect of the heating module.

[0016] As an embodiment of the utility model, the end surface of the roller body is provided with eight heating holes in the circumferential direction of the mandrel, and the heating module is provided with eight heating modules.

[0017] Therefore, preferably, the end surface of the roller body is provided with eight heating holes in the circumferential direction of the mandrel, and the corresponding heating module is also provided with eight heating modules, and the eight heating modules are synchronously heated.

[0018] As an embodiment of the utility model, the composite embossing roller for flexible materials further comprises a temperature measurement module, the end surface of the roller body is further provided with a temperature measurement hole, the temperature measurement module is installed in the temperature measurement hole, and the temperature measurement module is in communication connection with the heating module.

[0019] Therefore, the temperature measurement module is used for measuring the temperature of the roller body after heating, so as to control the start and stop of the heating module. Specifically, when the temperature measurement module detects that the temperature of the roller body is too low, the heating module is started, and when the temperature measurement module detects that the temperature of the roller body is too high, the heating module is stopped.

[0020] As an embodiment of the utility model, the composite embossing roller for flexible materials further comprises a control module, and the control module is in communication connection with the temperature measurement module and the heating module.

[0021] Thus, the setting control module is more flexible in unified control. Specifically, when the temperature measuring module detects that the roller body temperature is too low, the control module controls the heating module to start, and when the temperature measuring module detects that the roller body temperature is too high, the control module controls the heating module to stop.

[0022] As an embodiment of the present application, two or more temperature measuring holes are arranged on the end surface of the roller body around the circumference of the core shaft, and one temperature measuring hole corresponds to one temperature measuring module.

[0023] Thus, since the cross section of the roller body is circular, two or more temperature measuring holes are arranged on the end surface of the roller body around the circumference of the core shaft to better achieve temperature measurement or ensure the accuracy of temperature measurement.

[0024] As an embodiment of the present application, two temperature measuring holes are arranged on the end surface of the roller body around the circumference of the core shaft, and the temperature measuring module is provided with two temperature measuring holes.

[0025] Thus, preferably, two temperature measuring holes are arranged on the end surface of the roller body around the circumference of the core shaft, and the corresponding temperature measuring module is also provided with two temperature measuring holes. The two temperature measuring modules can improve the accuracy of temperature measurement on the one hand, and can be used as a backup on the other hand, so that the other one can normally measure the temperature when one of them fails.

[0026] As an embodiment of the present application, the surface layer embossing pattern is provided with seven.

[0027] Thus, preferably, the surface layer embossing pattern is provided with seven, and the seven surface layer embossing patterns are arranged continuously. In some embodiments, the number and position of the surface layer embossing patterns can be set according to the required pattern of the flexible material.

[0047] As shown in Figure 1 the prior art three-piece compression station and the surface layer embossing station are two separate stations, the three-piece compression assembly 200 and the surface layer embossing assembly 300 are arranged in front and back, the mold manufacturing cost is high and the production line is long, the required space is large, the energy consumption is high, and the relative positions of the three-piece compression pattern and the surface layer embossing pattern cannot be accurately controlled. The applicant found that the three-piece compression pattern 31 and the surface layer embossing pattern 32 can be arranged on the outer surface of the roller body 2, so that the three-piece compression station and the surface layer embossing station are combined into one, on the one hand, the mold manufacturing cost is reduced, the length of the production line is reduced, the production space is saved, and the production energy consumption is saved; on the other hand, since the three-piece compression pattern 31 and the surface layer embossing pattern 32 are engraved on the same roller, the relative positions of the two can be accurately controlled, and the quality of the flexible material is improved.

[0048] According to some embodiments of the present application, referring to Figures 2 to 5 , the present embodiment relates to a composite embossing roller 100 for flexible materials, comprising a mandrel 1, a roller body 2, and an embossing assembly 3, the roller body 2 is sleeved on the mandrel 1, and each end of the roller body 2 is provided with a protection step 21; the embossing assembly 3 is arranged on the outer surface of the roller body 2 and located between the two protection steps 21, the embossing assembly 3 comprises two three-piece compression patterns 31 and a surface layer embossing pattern 32 arranged in between, and the surface layer embossing pattern 32 is arranged between the two three-piece compression patterns 31.

[0049] The flexible material can be a paper diaper or a sanitary napkin, etc. The protection step 21 can be used to protect the embossing assembly 3 and play a positioning and protection role.

[0050] The technical solution of the present application combines the three-piece compression station and the surface layer embossing station into one, sets a composite embossing roller, arranges the three-piece compression pattern 31 and the surface layer embossing pattern 32 on the outer surface of the roller body 2, on the one hand, reduces the mold manufacturing cost, reduces the length of the production line, saves the production space, and saves the production energy consumption; on the other hand, since the three-piece compression pattern 31 and the surface layer embossing pattern 32 are engraved on the same roller, the relative positions of the two can be accurately controlled, and the quality of the flexible material is improved.

[0051] According to some embodiments of the present application, optionally, the height of the teeth of the surface layer embossed pattern 32 in the vertical direction is lower than the height of the teeth of the three-piece embossed pattern 31 in the vertical direction.

[0052] Therefore, since the fabric pressed by the three-piece embossed pattern has generally multiple layers, and the fabric pressed by the surface layer embossed pattern 32 has only one layer, the height of the teeth of the surface layer embossed pattern 32 in the vertical direction is set to be lower than the height of the teeth of the three-piece embossed pattern 31 in the vertical direction, so as to ensure that the two patterns are clear at the same time during embossing.

[0053] According to some embodiments of the present application, optionally, as shown in Figure 3 and Figure 4 the composite embossing roller 100 for flexible materials further comprises a heating module 4, and a heating hole 22 is formed on the end surface of the roller body 2 or the center of the mandrel 1, and the heating module 4 is arranged in the heating hole 22.

[0054] Therefore, the heating module 4 is beneficial to accelerate the molding of the surface layer embossed pattern 32 and the three-piece embossed pattern 31, and can also reduce the rebound amount after molding. The heating module 4 is a heating rod, which is a rod-shaped heating element that can be inserted into the heating hole arranged in the axial direction of the roller body.

[0056] Therefore, since the cross section of the roller body 2 is circular, the heating effect is better, and the end surface of the roller body 2 is uniformly provided with two or more heating holes 22 around the circumferential direction C of the mandrel, and the heating module 4 is arranged in the heating hole 22, so as to enhance the heating effect of the heating module 4.

[0060] In this way, the temperature measuring module 5 is used for measuring the temperature of the roller body 2 after heating, so as to control the start and stop of the heating module 4. Specifically, when the temperature measuring module 5 detects that the temperature of the roller body 2 is too low, the heating module 4 is started, and when the temperature measuring module 5 detects that the temperature of the roller body 2 is too high, the heating module 4 is stopped.

[0061] According to some embodiments of the present application, optionally, Figure 5 As shown, the composite embossing roller 100 for flexible materials further comprises a control module 6, and the control module 6 is in communication connection with the temperature measuring module 5 and the heating module 4 respectively.

[0062] In this way, the control module 6 is arranged to control uniformly, which is more flexible. Specifically, when the temperature measuring module 5 detects that the temperature of the roller body 2 is too low and feeds back to the control module 6, the control module 6 controls the heating module 4 to start, and when the temperature measuring module 5 detects that the temperature of the roller body 2 is too high and feeds back to the control module 6, the control module 6 controls the heating module 4 to stop.

[0063] According to some embodiments of the present application, optionally, Figure 4 As shown, the end face of the roller body 2 is uniformly provided with two or more temperature measuring holes 23 around the circumferential direction C of the core shaft, and one temperature measuring hole 23 corresponds to one temperature measuring module 5.
