The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. As will be apparent to those of ordinary skill in the art, embodiments described herein can be combined with other embodiments.

[0026] Please refer to Figure 1 , Figure 1 is a structural schematic diagram of the embosser in some embodiments of the application. Figure 1 The Y direction is the first direction, and the X direction is the second direction. The embosser provided by the embodiments of the application includes a first embossing unit 10 and a first composite unit 20. The first embossing unit 10 includes a plurality of groups of first embossing assemblies 11, which can be three groups, four groups, etc., and are not specifically limited here. Each group of first embossing assemblies 11 includes a main embossing roller 111 and a slave embossing roller 112 with opposite rotation directions, and a first embossing gap 113 is formed between the main embossing roller 111 and the slave embossing roller 112 for the paper base 63 to pass through for embossing operation. The first embossing gaps 113 are arranged at intervals in the first direction. This layout can separately emboss different layers in the multi-layer paper base 63, avoiding interference between the layers of the paper base 63.

[0027] The first composite unit 20 is arranged on one side of the first embossing unit 10 along the second direction, and the second direction intersects the first direction. Optionally, the first direction is perpendicular to the second direction. The first composite unit 20 includes a first auxiliary roller 21 and two first composite rollers 22. A first auxiliary gap 23 is formed between the first auxiliary roller 21 and one of the first composite rollers 22 for primary compounding of at least two adjacent layers of the paper base 63. A first composite gap 24 is formed between the two first composite rollers 22 for further compounding of the primary compounded paper base 63 with other layers of the paper base 63 into one layer, ensuring that the paper base 63 is preliminarily integrated into one after passing through the first composite unit 20. Optionally, the first auxiliary roller 21 and the two first composite rollers 22 are arranged at intervals in the first direction.

[0028] The terms "first", "second", "third" in the embodiments of the application are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second", "third" can explicitly or implicitly include at least one of the features. In the description of the application, the meaning of "a plurality of" is at least two, for example, two, three, etc., unless otherwise specifically limited.

[0029] In this embodiment, by setting multiple groups of first embossing assemblies 11, a paper substrate 63 transmission path is formed between any first embossing assembly 11 and the first composite unit 20, that is, multiple paper substrate 63 transmission paths are formed. When embossing and compounding multiple layers of paper substrates 63 are required, each layer of paper substrate 63 can be selectively embossed and compounded from one or more of the multiple paper substrate 63 transmission paths to achieve multiple different embossing patterns. Since the first embossing gaps 113 of each first embossing assembly 11 are arranged in a spaced-apart manner in the first direction, it can be ensured that each layer of paper substrate 63 does not interfere with each other during the embossing and compounding process.

[0030] The present application takes four groups of first embossing assemblies 11 as an example for illustration, the four groups of first embossing assemblies 11 are arranged in a staggered manner in the first direction to reduce the occupied space, as long as the first embossing gaps 113 of each first embossing assembly 11 can be spaced apart to avoid interference between the transmission paths formed between each first embossing assembly 11 and the first composite unit 20.

[0031] Please refer to Figure 1 and Figure 2 , Figure 2 is Figure 1 The numbering diagram of each first embossing assembly in the embodiment. The embossing patterns of each first embossing assembly 11 can be the same or different, in order to facilitate the explanation, the first embossing assemblies 11 in Figure 2 are numbered from bottom to top as 1-1, 1-2, 1-3, 1-4. All directional indications (such as up, down, left, right, front, back, etc.) in the present application are only used to explain the relative positional relationship, movement condition, etc. between components in a certain specific posture (as shown in the drawings), if the specific posture changes, the directional indications also change accordingly.

[0032] When embossing and compounding three layers of paper substrates 63 are required, four embossing patterns can be achieved if each layer needs to be embossed. Among them, the three layers of paper substrates 63 can be respectively embossed by the first embossing assemblies 11 numbered 1-1, 1-2, 1-3 and then enter the first composite unit 20 to synthesize a layer; the three layers of paper substrates 63 can be respectively embossed by the first embossing assemblies 11 numbered 1-1, 1-2, 1-4 and then enter the first composite unit 20 to synthesize a layer; the three layers of paper substrates 63 can be respectively embossed by the first embossing assemblies 11 numbered 1-2, 1-3, 1-4 and then enter the first composite unit 20 to synthesize a layer; the three layers of paper substrates 63 can be respectively embossed by the first embossing assemblies 11 numbered 1-1, 1-3, 1-4 and then enter the first composite unit 20 to synthesize a layer.

[0033] In some embodiments, each first embossing assembly 11 is connected with an adjusting assembly for adjusting the distance between the main embossing roller 111 and the slave embossing roller 112 in the first embossing assembly 11. The adjusting assembly can be connected with at least one of the main embossing roller 111 and the slave embossing roller 112. By adjusting the distance between the main embossing roller 111 and the slave embossing roller 112, the pressure and effect of embossing can be changed to meet different paper base 63 and embossing requirements.

[0034] Further, the main embossing roller 111 is a hollow steel roller, the roller surface is pre-fabricated with convex patterns, and the main embossing roller 111 is internally provided with a heating element. The heating element can adopt heat conduction oil circulation heating, steam / water circulation heating, electromagnetic induction heating, etc., which is not specifically limited here. By setting the main embossing roller 111 to heat the paper base 63, the embossing mark can be enhanced and repeated processing can be reduced. The surface of the slave embossing roller 112 is coated with elastic material, which cooperates with the main embossing roller 111 to form a depth-adjustable embossing mark.

[0035] The adjusting assembly can be a linear drive mechanism such as a pneumatic cylinder, a hydraulic cylinder, an oil cylinder, an electric push rod, or a swing arm mechanism, which is not specifically limited here as long as it can adjust the distance between the main embossing roller 111 and the slave embossing roller 112.

[0036] In some embodiments, the first auxiliary roller 21 is connected with a moving assembly 26 for driving the first auxiliary roller 21 to move to adjust the size of the first auxiliary gap 23. The moving assembly 26 can be a linear drive mechanism such as a pneumatic cylinder, a hydraulic cylinder, an oil cylinder, an electric push rod, or a swing arm mechanism, which is not specifically limited here.

[0037] Further, the embossing machine is configured with a PLC control system, which integrates automatic adjustment modules for the distance between the embossing rollers, the heating temperature, and the first auxiliary gap 23. The PLC control system realizes automatic operation and reduces the labor force.

[0038] Please refer to Figure 3 , Figure 3 is a structural schematic diagram of an embossing machine in another embodiment of the present application. In some embodiments, the embossing machine further includes a second embossing unit 30 and a second composite unit 40 arranged at intervals in the second direction. The second embossing unit 30 includes a plurality of second embossing assemblies 31, which can be three, four, etc., which is not specifically limited here. Each second embossing assembly 31 includes a main embossing roller 111 and a slave embossing roller 112 with opposite rotation directions, and the main embossing roller 111 and the slave embossing roller 112 in each second embossing assembly 31 form a second embossing gap 32 for the paper base 63 to pass through, and each second embossing gap 32 is arranged at intervals in the first direction.

[0039] The second composite unit 40 comprises a second auxiliary roller 41 and two second composite rollers 42. The second auxiliary roller 41 and one of the second composite rollers 42 form a second auxiliary gap 43 for primary compounding of at least two adjacent layers of the paper base 63. The two second composite rollers 42 form a second composite gap 44 for further compounding of the primary compounded paper base 63 with other layers of the paper base 63, so as to ensure that the paper base 63 is preliminarily integrated into one layer after passing through the first composite unit 20.

[0040] The paper base transmission path is formed between any one of the second embossing assemblies and the second composite unit. Each layer of the multi-layer paper base 63 enters the second composite unit 40 from one or more of the transmission paths to be compounded with other layers of the paper base 63.

[0041] Further, the second embossing unit 30 is symmetrically arranged with the first embossing unit 10, and the second composite unit 40 can be symmetrically arranged with the first composite unit 20. The first embossing unit 10, the first composite unit 20, the second embossing unit 30, and the second composite unit 40 are provided with a plurality of feeding guide rollers 61 and branch guide rollers 62. The feeding guide rollers 61 form a plurality of independent paper base 63 transmission paths extending to the first embossing assembly 11 and the second embossing assembly 31 through the branch guide rollers 62. It should be noted that the first embossing unit 10 and the second embossing unit 30 share the same set of feeding guide rollers 61, which can reduce the occupied space of the multi-layer paper base 63 during transmission to the first embossing unit 10 and the second embossing unit 30, so that the paper base 63 can be orderly delivered to the first embossing unit 10 and the second embossing unit 30. At the same time, the paper base 63 compounded into one layer by the first composite unit 20 is delivered to the paper stacking machine through a plurality of first discharge guide rollers 25, and the paper base 63 compounded into one layer by the second composite unit 40 is delivered into the paper stacking machine through a plurality of second discharge guide rollers 45. The arrangement direction of the plurality of first discharge guide rollers 25 is parallel to the arrangement direction of the plurality of second discharge guide rollers 45, so as to further reduce the occupied space.

[0042] Please continue to refer to Figure 3 In some embodiments, the embossing machine further comprises a paper supply unit 50 comprising a plurality of paper supply rollers 51, each of which is wound with a paper base 63. The paper supply unit 50, the first embossing unit 10, the first composite unit 20, the second composite unit 40, and the second embossing unit 30 are sequentially arranged in the second direction. The paper base 63 on each paper supply roller 51 is delivered to the first embossing unit 10 or the second embossing unit 30 through the feeding guide rollers 61. This provides a stable paper source for the entire embossing and compounding process.

[0043] Please refer to Figure 3 and Figure 4 , Figure 4 isFigure 3 The numbering diagram of each paper supply roller and partial paper base and the first embossing assembly in the embodiment. Exemplarily, the paper supply unit 50 is arranged on the side of the first embossing unit 10 away from the second embossing unit 30, and each feed guide roller 61 is arranged on the side of each first embossing assembly 11 and each second embossing assembly 31. The first embossing assembly 11 and the second embossing assembly 31 are respectively provided with four groups, and the paper supply roller 51 is provided with eight, in order to facilitate description, each of the paper supply rollers 51 in the first embossing unit 10 and the second embossing unit 30 is numbered as 1#, 2#, 3#, 4#, 5#, 6#, 7# and 8# respectively. Figure 4 The numbering diagram of each paper supply roller and partial paper base and the first embossing assembly in the embodiment. Exemplarily, the paper supply unit 50 is arranged on the side of the first embossing unit 10 away from the second embossing unit 30, and each feed guide roller 61 is arranged on the side of each first embossing assembly 11 and each second embossing assembly 31. The first embossing assembly 11 and the second embossing assembly 31 are respectively provided with four groups, and the paper supply roller 51 is provided with eight, in order to facilitate description, each of the paper supply rollers 51 in the first embossing unit 10 and the second embossing unit 30 is numbered as 1#, 2#, 3#, 4#, 5#, 6#, 7# and 8# respectively.

[0044] Optionally, the 1-8# paper supply rollers 51 can be sequentially and spaced apart in the first direction, wherein the paper base 63 wound on the 1-4# paper supply rollers 51 is conveyed to the second embossing unit 30 through the feed guide roller 61, and the paper base 63 wound on the 5-8# paper supply rollers 51 is conveyed to the first embossing unit 10 through the feed guide roller 61. It can be understood that the paper bases 63 released on each paper supply roller 51 are stacked with each other when conveyed on the feed guide roller 61, and the distance of the layer of the stacked paper bases 63 farthest away from the first embossing assembly 11 and the second embossing assembly 31 conveyed on the feed guide roller 61 is the longest, and the distance of the layer closest to the first embossing assembly 11 and the second embossing assembly 31 conveyed on the feed guide roller 61 is the shortest, so that each layer of the paper bases 63 can be sequentially conveyed to the corresponding first embossing assembly 11 and second embossing assembly 31, avoiding the interference of each paper base 63 when embossing and compounding.

[0045] In other embodiments, the 1-8# paper supply rollers 51 can also be sequentially and spaced apart in the second direction, and similarly, the paper base 63 wound on the 1-4# paper supply rollers 51 is conveyed to the second embossing unit 30 through the feed guide roller 61, and the paper base 63 wound on the 5-8# paper supply rollers 51 is conveyed to the first embossing unit 10 through the feed guide roller 61, which will not be described in detail here.

[0046] Optionally, the 1-4# paper supply rollers 51 and the 5-8# paper supply rollers 51 can also be arranged on two independent paper supply units 50 respectively, and the two paper supply units 50 are arranged symmetrically adjacent to the first embossing unit 10 and the second embossing unit 30 respectively, so that the paper base 63 on the 5-8# paper supply rollers 51 can directly enter the first embossing unit 10, and the paper base 63 on the 1-4# paper supply rollers 51 can directly enter the second embossing unit 30, without the need for long-distance transmission of the paper base 63 through the feed guide roller 61.

[0047] Optionally, the paper base 63 on the 5-8# paper supply rollers 51 can directly enter the corresponding first embossing assembly 11 through each branch guide roller 62, without the need for merging through the feed guide roller 61 and then separating through each branch guide roller 63 before entering the corresponding first embossing assembly 11.

[0048] Referring to Figure 3 In some embodiments, the first embossing unit 10 further comprises two groups of first paper guide rollers 13, respectively located at both sides of each first embossing assembly 11 in the first direction. The first paper guide rollers 13 are used to guide the paper bases 63 that do not pass through the first embossing gap 113 to enter the first compounding unit 20 for compounding with other paper bases 63.

[0049] Likewise, the second embossing unit 30 further comprises two groups of second paper guide rollers 33, respectively located at both sides of each second embossing assembly 31 in the first direction. The second paper guide rollers 33 are used to guide the paper bases 63 that do not pass through the second embossing gap 32 to enter the second compounding unit 40 for compounding with other paper bases 63.

[0050] In this embodiment, the two groups of first paper guide rollers 13 form transmission paths that do not perform embossing operation on the paper bases 63 between the first paper guide rollers 13 and the first compounding unit 20. When it is necessary to emboss and compound multiple layers of paper bases 63, each layer of paper bases 63 can be selectively entered into the first compounding unit 20 from the transmission path of each first paper guide roller 13 or each first embossing assembly 11 to form a layer after compounding, so as to realize multiple different embossing modes.

[0051] The following describes the embossing paths of the first embossing unit 10 and the first compounding unit 20 in different embossing modes when the paper bases 63 are compounded in four layers. As shown in Figure 4 , the paper bases 63 are sequentially numbered as a1 layer, a2 layer, a3 layer and a4 layer in the first direction.

[0052] Please refer to Figure 4 and Figure 5 , Figure 5 is Figure 3 the schematic diagram of the embossing paths of the embossing machine in an embossing mode in this embodiment. Among them, the a2 layer enters the first compounding unit 20 after being embossed by the No. 1-2 first embossing assembly 11, the a3 layer enters the first compounding unit 20 after being embossed by the No. 1-3 first embossing assembly 11, the a1 layer and the a4 layer enter the first compounding unit 20 from the two first paper guide rollers 13 respectively, and the a3 layer and the a4 layer enter the first compounding gap 24 after being initially compounded by the first auxiliary gap 23 to further form a layer with the a1 layer and the a2 layer.

[0053] Please refer to Figure 4 and Figure 6 , Figure 6 is Figure 3The embossing path of the embossing machine in another embossing mode in the embodiment is shown in the figure. In the other embossing mode, the a1 layer is embossed by the first embossing assembly No. 1-1 11 and then enters the first composite unit 20, the a2 layer is embossed by the first embossing assembly No. 1-2 11 and then enters the first composite unit 20, the a3 layer and the a4 layer enter the first composite unit 20 from the first paper guide roller 13 on one side, and after the a3 layer and the a4 layer are initially compounded through the first auxiliary gap 23, they enter the first composite gap 24 with the a1 layer and the a2 layer to further synthesize a layer.

[0054] Please refer to Figure 4 and Figure 7 , Figure 7 is Figure 3 The embossing path of the embossing machine in another embossing mode in the embodiment is shown in the figure. In the other embossing mode, the a1 layer is embossed by the first embossing assembly No. 1-1 11 and then enters the first composite unit 20, the a2 layer is embossed by the first embossing assembly No. 1-2 11 and then enters the first composite unit 20, the a3 layer is embossed by the first embossing assembly No. 1-3 11 and then enters the first composite unit 20, the a4 layer is embossed by the first embossing assembly No. 1-4 11 and then enters the first composite unit 20, and after the a3 layer and the a4 layer are initially compounded through the first auxiliary gap 23, they enter the first composite gap 24 with the a1 layer and the a2 layer to further synthesize a layer.

[0055] In other embodiments, the embossing machine further comprises a plurality of embossing units and composite units corresponding to the embossing units, which can be three, four, etc. The specific structure of each embossing unit is set with reference to the first embossing unit 10, and the specific structure of each composite unit is set with reference to the first composite unit 20, which will not be described here. Each embossing unit is arranged adjacent to the corresponding composite unit, and the efficiency of the embossing machine can be improved by arranging multiple embossing units and composite units. At the same time, each embossing unit is arranged in sequence and at intervals along the second direction to ensure that the paper base 63 can be orderly transported into each embossing unit for embossing.

[0056] Please refer to Figure 3 , the working process of the embossing machine in the embodiment is as follows: after starting the equipment, the paper feeding roller 51 of the paper feeding unit 50 starts to rotate and gradually releases the paper base 63 wound thereon. The paper base 63 is guided by the feeding guide roller 61 and transported to the first embossing unit 10 or the second embossing unit 30 according to the preset path.

[0057] The paper base 63 entering the first embossing unit 10 will pass through the first embossing gap 113 of the corresponding first embossing assembly 11 according to its layer and preset process flow. In the first embossing gap 113, the paper base 63 is embossed by the main embossing roller 111 and the slave embossing roller 112 rotating in opposite directions, so that the paper surface forms a specific pattern. The paper base 63 not passing through the first embossing gap 113 is guided by the first paper guide roller 13 and directly enters the first compounding unit 20. In the first compounding unit 20, firstly, the adjacent two layers of paper base 63 enter the first auxiliary gap 23 and are initially compounded by the first auxiliary roller 21 and the corresponding first compounding roller 22, so that the two layers of paper are initially adhered. Then, the paper base 63 after the initial compounding enters the first compounding gap 24 together with other layers of paper base 63, and is further compounded into one layer by the two first compounding rollers 22, thereby completing the initial layering operation.

[0058] The paper base 63 entering the second embossing unit 30 passes through the second embossing gap 32 of the corresponding second embossing assembly 31 according to the preset path, and is embossed by the main embossing roller 111 and the slave embossing roller 112 in the second embossing assembly 31. The paper base 63 not passing through the second embossing gap 32 directly enters the second compounding unit 40. Then, the paper base 63 after the second embossing is layered in the second compounding unit 40 to further enhance the bonding strength between the layers of paper.

[0059] The paper base 63 after the layering in the first compounding unit 20 and the second compounding unit 40 is conveyed to the paper stacking machine by the first discharge guide roller 25 and the second discharge guide roller 45, respectively.

[0060] The above only describes some embodiments of the present application, and does not limit the protection scope of the present application. Any equivalent device or equivalent process transformation using the content of the present application specification and drawings, or direct or indirect application in other related technical fields, is also included in the patent protection scope of the present application.
