Description

Technical Field

[0001] The present application relates to the technical field of embossing and stamping, and particularly to an aluminum foil paper stamping and pressing device. Background Art

[0002] In the production process of aluminum foil paper, embossing and stamping is a common processing method. The traditional stamping method usually applies pressure to both ends of the embossing roller by applying force at both ends, so as to realize the embossing and stamping of aluminum foil paper.

[0003] Although this method is simple and easy to implement, there are some problems in actual operation. First of all, the material of the embossing roller is relatively soft. When the embossing roller stamps the paper, force is applied at both ends, resulting in less force in the middle of the embossing roller, leading to uneven embossing. Moreover, as the length of the embossing roller increases, the effect is more obvious, thus reducing the stamping quality of the paper. Secondly, during the embossing process of the embossing roller, if the pressure changes, it will also reduce the stamping quality of the paper. At the same time, when the required pressure of the embossing roller changes, manual adjustment is needed, with low automation and long time consumption, thus reducing the stamping quality and efficiency of the paper. Summary of the Invention

[0004] In order to improve the stamping quality and efficiency of paper, the present application provides an aluminum foil paper stamping and pressing device.

[0005] An aluminum foil paper stamping and pressing device provided by the present application adopts the following technical solutions: An aluminum foil paper stamping and pressing device includes a frame, a bearing roller, two moving blocks, an embossing roller, a plurality of pressing assemblies, a first pressing mechanism and a plurality of second pressing mechanisms; The bearing roller is rotatably installed on the frame. The two moving blocks are slidably arranged on the frame and are connected by a connecting rod. The two ends of the embossing roller are rotatably arranged on the two moving blocks and are located above the bearing roller and cooperate with the bearing roller to stamp the paper; the plurality of pressing assemblies are arranged at intervals along the axis of the embossing roller and are slidably arranged on the connecting rod in a direction close to or away from the embossing roller. The first pressing mechanism is used to push the two moving blocks to move and is used to adjust the pressure of the embossing roller on the paper. The plurality of second pressing mechanisms are correspondingly arranged with the plurality of pressing assemblies and are used to drive the pressing assemblies to move and are used to adjust the thrust of the pressing assemblies on the embossing roller. The first pressing mechanism includes: An airbag one, which is arranged on the frame and presses against the upper surface of the moving block; A control component one, which is communicated with the airbag one and is used to control the thrust of the airbag one on the moving block; A support spring, which is arranged on the frame and connected to the moving block. After the airbag one contracts, the moving block moves back under the elastic force of the support spring; The first pressure detector is arranged on the frame and abuts against the moving block. The first pressure detector is used to detect the pressure of the embossing roller on the paper and is electrically connected to the first control component.

[0006] By adopting the above technical solution, when the first pressing mechanism is activated, the control airbag is inflated, and the airbag pushes the moving block and the embossing roller downward, thereby increasing the pressure of the embossing roller on the paper. Or, when the airbag deflates, the supporting spring pushes the moving block and the embossing roller upward, thereby reducing the pressure of the embossing roller on the paper, so as to adjust the pressure of the embossing roller on the paper; the movement of the two moving blocks drives the connecting rod, multiple pressing components and multiple second pressing mechanisms to move simultaneously. The multiple pressing components are arranged along the axis of the embossing roller and are used to support and position the embossing roller. At the same time, the multiple second pressing mechanisms adjust the thrust on the pressing components according to the thrust of the embossing roller on the pressing components, so that the pressure of the embossing roller on the paper tends to be uniform, and the adjustment of the paper pressure can be automatically realized through the cooperation of the first pressing mechanism and the second pressing mechanism.

[0007] The multiple pressing components support and position the embossing roller at multiple places. Moreover, through the design of the connecting rod, the supporting strength of the multiple pressing components on the embossing roller can be ensured, and the pressure of the multiple pressing components is dispersed, further improving the supporting effect on the embossing roller. Moreover, even when the connecting rod is deformed and the pressure is reduced, the second pressing mechanism can still continue to adjust the supporting force of the pressing component on the embossing roller, so as to keep the overall pressure of the embossing roller on the paper consistent, and can also be adjusted in real time according to the pressure change, greatly improving the quality and efficiency of paper embossing. Moreover, the air pressure adjustment can quickly reach the required effect, and the structure is simple and stable with low maintenance cost, further improving the quality and efficiency of paper embossing.

[0008] Optionally, an installation frame is arranged on the frame. A guiding groove is formed on the installation frame. The moving block is slidably installed on the guiding groove. The first airbag is placed on the installation frame and deforms along the sliding direction of the moving block when the first airbag deforms.

[0009] By adopting the above technical solution, the design of the installation frame can protect the first airbag, improve the service life of the first airbag, and reduce the adverse effects of the outside world on the expansion of the first airbag. Moreover, the design of the guiding groove enables the deformation of the first airbag to be concentrated on driving the moving block to move, thereby greatly improving the efficiency during the adjustment process and ensuring the stability after adjustment, and improving the quality and efficiency of paper embossing.

[0010] Optionally, the second pressing mechanism includes: The second airbag is arranged on the connecting rod and is used to push the pressing component to abut against the embossing roller; The second control component is communicated with the second airbag and is used to control the thrust of the second airbag on the pressing component; Pressure detector two, which is arranged on the connecting rod, is electrically connected to the control component two and is used to detect the thrust of the embossing roller on the pressing component.

[0011] By adopting the above technical solution, the connecting rod moves to drive the pressing component to approach the embossing roller, so that the pressing component abuts against the embossing roller for support. If the pressing component does not contact the embossing roller after the movement of the connecting rod is completed, the control component two is activated to inflate the airbag two. The airbag two expands to push the pressing component against the embossing roller. The pressure detector two detects the thrust of the embossing roller on the pressing component, and the paper starts to be embossed. If the pressure of the embossing roller on the pressing component changes, the control component two is continuously activated to drive the pressing component to move, so that the pressure of the embossing roller on the paper is balanced, improving the embossing quality and efficiency of the paper.

[0012] Optionally, the pressing component includes: The pressing block is slidably arranged on the connecting rod in the direction of approaching or departing from the embossing roller; The pressing roller is rotatably installed on the pressing block and abuts against the embossing roller to achieve support.

[0013] By adopting the above technical solution, the airbag two is used to drive the pressing block and the pressing roller to move, so that the pressing roller presses against the embossing roller. The embossing roller rotates to drive the pressing roller to rotate, thereby realizing the support for the embossing roller and reducing the risk of wear caused by relative rotation between the two.

[0014] Optionally, a hydraulic mechanism connected to the moving block is arranged on the frame. The hydraulic mechanism includes: The fixed block is arranged on the frame and a hydraulic cavity is opened inside; The hydraulic block is slidably arranged in the hydraulic cavity and divides the hydraulic cavity into a first chamber and a second chamber that are independent of each other and are both filled with liquid; The hydraulic rod is arranged on the hydraulic block, is connected to the moving block and slidably penetrates through the fixed block; The hydraulic component is communicated with the first chamber and the second chamber and is used for inputting or outputting liquid. When the hydraulic component is opened, the moving block moves to drive the hydraulic rod and the hydraulic block to move and realize the flow of liquid in the first chamber and the second chamber. After the movement of the moving block is completed, the hydraulic component is closed and the hydraulic block is positioned by the liquid.

[0015] By adopting the above technical solutions, although the air pressure adjustment can quickly achieve the desired effect, the gas is easily affected by external factors such as temperature, and the stability of the air pressure is relatively low. It is difficult to maintain a stable pressure of the embossing roller on the paper for a long time, which reduces the embossing quality of the paper. Moreover, it is also easy to need to adjust the pressure multiple times, which also reduces the embossing efficiency of the paper. And directly adopting hydraulic adjustment, the adjustment efficiency is slow, the time spent is long, which reduces the embossing efficiency of the paper. At the same time, the liquid needs to use structures such as a hydraulic pump, which makes the structure complex and increases the embossing cost.

[0016] When adjustment is needed, the hydraulic component is started and opened so that the liquid in the first chamber and the second chamber can convect. The slider moves to drive the hydraulic rod and the hydraulic block to move. The movement of the hydraulic block makes the liquid in the first chamber and the second chamber convect. After the adjustment is completed, the hydraulic component is closed so that the liquid located in the first chamber and the second chamber cannot flow. The first chamber and the second chamber are formed by the cooperation of the hydraulic block and the hydraulic chamber, so that the liquid in the first chamber and the second chamber can position the hydraulic block, reducing the risk of displacement of the hydraulic block and the risk of change in the pressure of the embossing roller on the paper. Therefore, through the joint cooperation of air pressure and hydraulic pressure, the embossing quality and efficiency of the paper are improved, and at the same time, structures such as a hydraulic pump do not need to be used, thus reducing the embossing cost.

[0017] At the same time, through the cooperation of air pressure and hydraulic pressure, the hydraulic pressure can position the position of the embossing roller. At the same time, the cooperation of air pressure and hydraulic pressure also reduces the pressure of the liquid on the hydraulic block, further reducing the requirement for liquid sealing under high pressure, that is, making the hydraulic mechanism more stable and with lower cost, further improving the embossing quality and efficiency of the paper and reducing the embossing cost. Moreover, the liquid flows in the first chamber and the second chamber, reducing the risk of pollution caused by the liquid flowing out.

[0018] Optionally, the hydraulic component includes: A hydraulic pipe, the two ends of which are respectively communicated with the ends of the first chamber and the second chamber that are far away from each other; A control valve, used to control the opening and closing of the hydraulic pipe.

[0019] By adopting the above technical solutions, when movement is needed, the control valve is opened so that the liquid located in the first chamber and the second chamber flows. When the movement is completed, the control valve is closed so that the liquid located in the first chamber and the second chamber cannot flow. Thus, the liquid can position the embossing roller, improving the embossing quality and efficiency of the embossing roller on the paper.

[0020] Optionally, sealing rings for sealing are respectively clamped and installed at both ends of the hydraulic block close to the first chamber and the second chamber.

[0021] By adopting the above technical solution, the sealing ring can seal the liquid, reducing the risk of the liquid in the first chamber and the second chamber flowing into each other through the gap between the hydraulic block and the hydraulic chamber, further improving the positioning effect of the hydraulic block on the embossing roller, and enhancing the embossing quality and efficiency of the paper.

[0022] Optionally, it further includes two sets of pressure application seat bodies that are mirror - set with respect to the perpendicular bisector of the axis of the embossing roller. Two moving grooves corresponding to the two sets of pressure application seat bodies are provided on the frame. Each set of pressure application seat bodies includes a plurality of pressure application seat monomers that are slidably mounted on the moving grooves along the axis of the embossing roller. The plurality of pressure application components are respectively arranged on the two sets of pressure application seat bodies. Two driving components are provided on the frame, and the two driving components are used to drive the two sets of pressure application seat bodies to move simultaneously and keep the distance between adjacent two pressure application seat monomers located on the same moving groove consistent.

[0023] By adopting the above technical solution, the paper generally passes through the middle position of the embossing roller, and the width of the paper will change. When the width of the paper becomes smaller, the distance between the plurality of pressure application components is larger, that is, there are some pressure application components located outside the paper; when the width of the paper becomes larger, the distance between the plurality of pressure application components is smaller, that is, there is a part of the paper located outside the plurality of pressure application components. Thus, it will reduce the supporting and positioning effect of the pressure application components on the embossing roller and increase the risk of uneven pressure of the embossing roller on the paper.

[0024] After the width of the paper changes, the driving component drives the plurality of pressure application seat monomers in the two sets of pressure application seat bodies to move simultaneously, making the positions of the plurality of pressure application seat monomers adapt to the position of the paper, that is, the positions of the plurality of pressure application components adapt to the position of the paper, and the plurality of pressure application components are evenly arranged. Thus, it further improves the supporting and positioning effect of the pressure application components on the embossing roller, reduces the risk of uneven pressure of the embossing roller on the paper, and improves the embossing quality and efficiency of the paper.

[0025] Optionally, the driving component includes: A plurality of driving blocks, which are respectively arranged on the plurality of pressure application seat monomers. The adjacent two driving blocks are connected by a driving spring. The pressure application seat monomers located at the mutually - approaching ends of the two sets of pressure application seat bodies abut against each other for positioning and keep the driving spring in a compressed state all the time; A driving member, which is arranged on the connecting rod. The two driving members are connected to the pressure application seat monomers located at the mutually - distant ends of the two sets of pressure application seat bodies.

[0026] By adopting the above technical solution, two driving members drive two pressure seat monomers to move simultaneously. The movement of the pressure seat monomer drives the pressure seat monomer connected thereto through a driving spring, and so on, thereby driving multiple pressure seat monomers to move simultaneously. Therefore, the movement of two driving members can achieve the simultaneous movement of multiple pressure seat monomers, and the multiple pressure seat monomers located on the same movement groove are evenly distributed, greatly improving the convenience and stability of adjustment, and improving the quality and efficiency of paper embossing.

[0027] Optionally, a lubrication assembly for lubrication is provided on the pressure seat monomer. A lubrication groove is provided on the pressure seat monomer. The lubrication assembly includes: A lubricating sponge is arranged on the lubrication groove and absorbs lubricating oil; A plurality of balls are rotatably installed on the pressure seat monomer and press against the lubricating sponge and the movement groove. When the pressure seat monomer moves, it drives the plurality of balls to rotate and is used to add lubricating oil to the movement groove.

[0028] By adopting the above technical solution, when the pressure seat monomer moves, it drives the plurality of balls to move. The movement of the balls causes the lubricating oil on the lubricating sponge to be applied to the movement groove, thereby reducing the risk of jamming of the pressure seat monomer and the risk of uneven distribution of the plurality of pressure seat monomers, and improving the quality and efficiency of paper embossing; through the cooperation of the balls and the sponge, the added lubricating oil is moderate, and when the pressure seat monomer does not move, the lubricating oil is not added, so that the lubrication process is stable and fuel-efficient.

[0029] In summary, the present application includes at least one of the following beneficial technical effects: 1. Multiple pressure application components support and position the embossing roller at multiple locations. The pressure of multiple pressure application components is dispersed through the connecting rod, so as to make the overall pressure of the embossing roller on the paper consistent, and it can also be adjusted in real time according to the pressure change, greatly improving the quality and efficiency of paper embossing. Moreover, the air pressure adjustment can quickly achieve the required effect, and the structure is simple and stable with low maintenance cost, further improving the quality and efficiency of paper embossing.

[0030] 2. Through the joint cooperation of air pressure and hydraulic pressure, the positioning effect of the embossing roller can be improved. At the same time, the cooperation of air pressure and hydraulic pressure also reduces the pressure of the liquid on the hydraulic block, further reducing the requirement for liquid sealing under high pressure. At the same time, structures such as hydraulic pumps are not required, so that the hydraulic mechanism is more stable and the cost is lower, further improving the embossing quality and efficiency of paper and reducing the embossing cost.

Detailed implementation manners

[0033] The following further elaborates on this application in detail.

[0034] The embodiment of this application discloses an aluminum foil paper embossing and pressing device.

[0035] Refer to Figure 1 and Figure 2, the aluminum foil stamping and pressing device includes a frame 1, a pressure-bearing roller 11, two moving blocks 12, a embossing roller 13, a plurality of pressing components 5, a first pressing mechanism 2 and a plurality of second pressing mechanisms 6. The pressure-bearing roller 11 is rotatably installed on the frame 1 and is in a horizontal state. The two moving blocks 12 are arranged at intervals along the axis of the pressure-bearing roller 11 and are located above the pressure-bearing roller 11. The two moving blocks 12 are vertically slidably installed on the frame 1 and are connected to each other through a connecting rod 14. The axis of the embossing roller 13 is parallel to the axis of the pressure-bearing roller 11. The two ends of the embossing roller 13 are rotatably installed on the opposite ends of the two moving blocks 12, and the axes of the embossing roller 13 and the pressure-bearing roller 11 are located in the same vertical plane and are cooperated to press the paper; the plurality of pressing components 5 are arranged at intervals along the axis of the embossing roller 13 and are slidably arranged on the connecting rod 14 in a direction close to or away from the embossing roller 13. The first pressing mechanism 2 is used to push the two moving blocks 12 to move and is used to adjust the pressure of the embossing roller 13 on the paper; the plurality of second pressing mechanisms 6 are correspondingly arranged with the plurality of pressing components 5 and are used to drive the pressing components 5 to move and are used to adjust the thrust of the pressing components 5 on the embossing roller 13.

[0036] The first pressing mechanism 2 includes an airbag one 21, a support spring 22, a control component one 3 and a pressure detector one 23. An installation frame 17 is fixedly installed on the frame 1 and above the moving block 12. A vertical guiding groove 171 is opened at the bottom end of the installation frame 17. The top end of the moving block 12 is vertically slidably installed on the guiding groove 171. An installation hole one 172 communicating with the guiding groove 171 is opened on the side wall of the installation frame 17. An installation plate one 173 is detachably installed on the installation hole one 172. The airbag one 21 can be placed in the guiding groove 171 through the installation hole one 172, and then the installation plate one 173 is fixedly installed to block the installation hole one 172. The setting of the guiding groove 171 enables the airbag one 21 to deform along the direction of the guiding groove 171, that is, the sliding direction of the moving block 12 when deforming, greatly improving the pressing effect and efficiency of the airbag one 21 on the moving block 12.

[0037] The control component one 3 is communicated with the airbag one 21 and is used to control the thrust of the airbag one 21 on the moving block 12. The control component one 3 includes an air inlet pipe 31 and an air outlet pipe 32. The air inlet pipe 31 and the air outlet pipe 32 are both fixedly installed on the airbag one 21 and both extend to the outside of the installation frame 17 through the installation plate one 173; an air inlet valve 33 is fixedly installed on the air inlet pipe 31 and an air outlet valve 34 is fixedly installed on the air outlet pipe 32. The air inlet pipe 31 is communicated with the air source, and a control box for controlling the opening and closing of the air inlet valve 33 and the air outlet valve 34 is fixedly installed on the frame 1.

[0038] The support spring 22 is fixedly installed on the frame 1 and is located below the moving block 12. The top end of the support spring 22 is fixedly connected to the bottom end of the moving block 12. The support spring 22 is used to drive the embossing roller 13 to move upward. When the airbag one 21 expands, it drives the moving block 12 to move downward. When the airbag one 21 contracts, the support spring 22 can drive the embossing roller 13 to move upward back to its original position.

[0039] The first pressure detector 23 is fixedly installed on the frame 1. The first pressure detector 23 is electrically connected to the control box and is used to transmit the detected value to the control box. The control box controls the opening and closing of the intake valve 33 and the outlet valve 34 according to the value. A first block 24 is fixedly installed on the side wall of the moving block 12 and above the first pressure detector 23. When the moving block 12 moves downward, it pushes the first block 24 closer to the first pressure detector 23, so that the first block 24 presses against the first pressure detector 23 to detect the pressure of the embossing roller 13 on the paper. At the same time, it can also zero the pressure value of the first pressure detector 23, that is, when the embossing roller 13 contacts the paper, the value of the first pressure detector 23 is zero. As the moving block 12 and the embossing roller 13 move, the value of the first pressure detector 23 increases, so as to realize the detection of the pressure on the paper.

[0040] Refer to Figures 1 - 3 , the connecting rod 14 includes two connecting sections 15 fixedly connected to the moving block 12 and mounting sections 16 connecting the two ends of the connecting sections 15 far from the moving block 12. The connecting sections 15 are arranged perpendicular to the axis of the embossing roller 13, and the mounting sections 16 are arranged parallel to the axis of the embossing roller 13. The mounting sections 16 are located above the axis of the embossing roller 13, or the mounting sections 16 are located directly above the embossing roller 13. Two moving grooves 161 are opened on the side wall of the mounting section 16 close to the embossing roller 13 along the axis of the embossing roller 13. The two moving grooves 161 are mirror-symmetrically arranged with respect to the perpendicular bisector of the axis of the embossing roller 13.

[0041] Refer to Figure 1 、 Figure 3 and Figure 4 , it further includes two groups of pressure-applying seat bodies 18 that are mirror-symmetrically arranged with respect to the perpendicular bisector of the axis of the embossing roller 13. The two groups of pressure-applying seat bodies 18 are correspondingly arranged with the two moving grooves 161. Each group of pressure-applying seat bodies 18 includes a plurality of pressure-applying seat units 181 slidably mounted on the moving grooves 161 along the axis of the embossing roller 13. A plurality of pressure-applying assemblies 5 are respectively arranged on the plurality of pressure-applying seat units 181, that is, one pressure-applying assembly 5 is arranged on each pressure-applying seat unit 181. Two driving assemblies 9 corresponding to the two groups of pressure-applying seat bodies 18 are arranged on the mounting section 16. The driving assemblies 9 are used to drive the two groups of pressure-applying seat bodies 18 to move simultaneously, and keep the distance between two adjacent pressure-applying seat units 181 located on the same moving groove 161 consistent, so that the plurality of pressure-applying seat units 181 located on the same moving groove 161 are evenly arranged.

[0042] When the width of the paper changes, the driving assembly 9 is used to adjust the positions of the plurality of pressure-applying seat units 181 and the pressure-applying assemblies 5 located on the pressure-applying seat units 181, so that the positions of the plurality of pressure-applying assemblies 5 can be adapted to the width of the paper, thereby further improving the supporting and positioning effect of the pressure-applying assemblies 5 on the embossing roller 13, and improving the embossing quality and efficiency of the embossing roller 13 on the paper.

[0043] Referring to Figure 3 and Figure 4

[0044]

[0043]

[0045] Figure 3

[0046] Referring to Figure 1 and Figure 4, the pressing component 5 is located above the axis of the embossing roller 13. The pressing component 5 includes a pressing block 51 and a pressing roller 52. A sliding groove 53 is formed at one end of the pressing seat unit 181 close to the embossing roller 13. The pressing block 51 is slidably arranged on the sliding groove 53 in a direction close to or away from the embossing roller 13. The sliding direction of the pressing block 51 is perpendicular to the axis direction of the embossing roller 13, and one end of the pressing block 51 close to the embossing roller 13 extends outside the sliding groove 53. The pressing roller 52 is rotatably installed on one end of the pressing block 51 close to the embossing roller 13, and the axis of the pressing roller 52 is parallel to the axis of the embossing roller 13.

[0047] The second pressing mechanism 6 is activated to push the pressing block 51 and the pressing roller 52 close to the embossing roller 13, so that the embossing roller 13 abuts against the embossing roller 13 for support. When the embossing roller 13 performs embossing, a reverse thrust on the pressing roller 52 is generated. The second pressing mechanism 6 can position the pressing roller 52. The pressing roller 52 abuts against the embossing roller 13 for support. If the thrust of the embossing roller 13 on the pressing roller 52 increases, the second pressing mechanism 6 also increases the thrust on the pressing roller 52, further improving the support effect on the embossing roller 13, making the pressure of the embossing roller 13 on the paper more uniform, and improving the embossing quality of the paper.

[0048] Refer to Figure 1 and Figure 4 , the second pressing mechanism 6 includes an air bag two 61, a control component two 62, and a pressure detector two 63. An installation hole two 185 communicating with the sliding groove 53 is formed on the upper surface of the pressing part 183. An installation plate two 186 is detachably installed on the installation hole two 185. The air bag two 61 can be placed in the moving groove 161 through the installation hole two 185, and then the installation plate two 186 is fixedly installed to block the installation hole two 185. The setting of the moving groove 161 enables the air bag two 61 to deform along the direction of the sliding groove 53, that is, the sliding direction of the pressing block 51 when deforming, greatly improving the pressing effect and efficiency of the air bag two 61 on the pressing block 51.

[0049] Refer to Figure 1 , Figure 2 and Figure 4, the control component two 62 is connected to the airbag two 61 and is used to control the intake or exhaust of the airbag two 61. The control component two 62 is used to control the thrust of the airbag two 61 on the pressing block 51. The structure of the control component two 62 is the same as that of the control component one 3. The control component two 62 passes through the mounting plate two 186, which will not be elaborated here; the pressure detector two 63 is fixedly installed at one end of the pressing part 183 close to the embossing roller 13. A block two 54 is fixedly installed on the pressing block 51. When the pressing roller 52 abuts against the embossing roller 13, the block two 54 abuts against the detection element of the pressure detector two 63 to detect the pressure on the pressure detector two 63. The pressure detector two 63 is used to transmit the detection data to the control component two 62. At the same time, the rotation of the embossing roller 13 drives the rotation of the pressing roller 52, reducing the risk of relative rotation and wear between the two.

[0050] When the embossing roller 13 generates a thrust on the pressing roller 52 during embossing, the airbag two 61 can first support and position the pressing block 51. As the thrust increases, the embossing roller 13 pushes the pressing roller 52 closer to the pressing roller 52, that is, drives the pressing block 51 and the block two 54 closer to the pressure detector two 63. The pressure detector two 63 detects that the pressure value becomes larger, and the control component two 62 starts to inflate the airbag two 61 to increase the supporting force of the pressing roller 52 on the embossing roller 13 until the detection value of the pressure detector two 63 returns to the original value; if the thrust of the embossing roller 13 on the pressing roller 52 decreases during embossing, that is, the pressure detected by the pressure detector two 63 becomes smaller, the control component two 62 controls the airbag two 61 to deflate, reducing the supporting force of the pressing roller 52 on the embossing roller 13, that is, the embossing roller 13 pushes the pressing roller 52 and the pressing block 51 closer to the pressure detector two 63 until the detection value of the pressure detector two 63 returns to the original value, thereby reducing the probability of excessive extrusion and damage to the pressing roller 52 and the embossing roller 13, and improving the embossing quality and efficiency of the paper.

[0051] Refer to Figure 1 、 Figure 2 and Figure 5 , a hydraulic mechanism 7 connected to the moving block 12 is arranged on the frame 1. There are two hydraulic mechanisms 7 and they are arranged corresponding to the two moving blocks 12; the hydraulic mechanism 7 includes a fixed block 71, a hydraulic block 72, a hydraulic rod 73 and a hydraulic component 8. The fixed block 71 is fixedly installed on the frame 1 and is located on one side of the moving block 12. A vertical hydraulic cavity 74 is opened in the fixed block 71; the hydraulic block 72 is vertically slidably installed on the hydraulic cavity 74 and divides the hydraulic cavity 74 into two independent first chambers 75 and second chambers 76. Both the first chamber 75 and the second chamber 76 are filled with liquid. Sealing rings for sealing are clamped and installed on the top and bottom side walls of the hydraulic block 72.

[0052] The hydraulic rod 73 is fixedly installed on the upper surface of the hydraulic block 72 and vertically penetrates upward through the fixed block 71 to extend above the fixed block 71. At the same time, the hydraulic rod 73 is slidably arranged in the fixed block 71, and a rod body 77 fixedly connected to the side wall of the moving block 12 is fixedly installed at the top end of the hydraulic rod 73.

[0053] The hydraulic component 8 is communicated with the inside of the first chamber 75 and the second chamber 76 and is used for inputting or outputting liquid. When the moving block 12 needs to move, the hydraulic component 8 is opened. When the moving block 12 moves, it drives the hydraulic rod 73 and the hydraulic block 72 to move and realizes the flow of liquid in the first chamber 75 and the second chamber 76. After the moving block 12 finishes moving, the hydraulic component 8 is closed and the hydraulic block 72 is positioned by the liquid, so as to realize the positioning of the positions of the moving block 12 and the embossing roller 13.

[0054] The hydraulic component 8 includes a hydraulic pipe 81 and a control valve 82. The two ends of the hydraulic pipe 81 are respectively communicated with the mutually remote ends of the first chamber 75 and the second chamber 76; the control valve 82 is fixedly installed on the hydraulic pipe 81 and is used for controlling the opening and closing of the hydraulic pipe 81. Before the moving block 12 moves, the control valve 82 is opened. When the moving block 12 moves, it drives the hydraulic block 72 to move, so that the liquid flows in the first chamber 75 and the second chamber 76. After the moving block 12 finishes moving, the control valve 82 is closed, so that the liquid is located in the first chamber 75 and the second chamber 76, so as to realize the positioning of the positions of the hydraulic block 72, the moving block 12 and the embossing roller 13, improve the positioning effect of the embossing roller 13, and improve the embossing quality and efficiency of the paper.

[0055] The working principle of the embodiment of the present application is as follows: The pressure-bearing roller 11 and the embossing roller 13 cooperate to emboss the paper. The airbag one 21 and the hydraulic block 72 are used to position the embossing roller 13. The pressure detector one 23 is used to detect the pressure of the embossing roller 13 on the paper. At the same time, the pressure detector two 63 detects the pressure of the embossing roller 13 on the pressing roller 52; when the pressure detected by the pressure detector two 63 changes, the control component two 62 starts to control the airbag two 61 to intake or exhaust air, so that the pressure tends to be balanced. At the same time, when the pressure detector one 23 detects a pressure change, the control valve 82 is opened, and the control component one 3 starts to control the airbag two 61 to intake or exhaust air, so as to drive the moving block 12 and the embossing roller 13 to move to realize the adjustment of the pressure. When the moving block 12 moves, it drives the hydraulic block 72 to move, and the liquid moves in the first chamber 75 and the second chamber 76. After the adjustment is completed, the control component one 3 and the control valve 82 are closed, so as to reduce the risk of uneven pressure on the paper and can be automatically controlled, thereby improving the embossing quality and efficiency of the paper.

[0056] When the paper width changes, the two driving members 92 are simultaneously activated to drive the pressing seat unit 181 connected thereto to move. The movement of the pressing seat unit 181 drives the movement of multiple other pressing seat units 181 through the support spring 22, enabling the multiple pressing assemblies 5 to adapt to different paper widths, further improving the pressing quality and efficiency of the paper.

[0057] The above are all preferred embodiments of this application. The protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
