Description

Technical Field

[0001] The utility model relates to the technical field of paper embossing, in particular to a four-side embossing device for paper. Background Art

[0002] The four-side embossing device for tissue paper is widely used in the tissue paper processing industry. By embossing patterns with specific patterns on the four sides of the tissue paper, it improves product quality and user experience. However, the embossing roller of the traditional four-side embossing device and the rolling shaft that drives the active roller to transport the tissue paper are insufficient in stability during high-speed operation. Because the embossing roller's pressure control on the tissue paper is not precise enough, the pressure in some areas is greater, resulting in the embossing pattern being too deep and damaging the tissue paper, while the pressure in other areas is less, resulting in the embossing effect being unclear or the pattern being blurred. The uneven force on the tissue paper greatly affects the consistency and appearance quality of the product. During high-speed rotation, the embossing roller and the rolling shaft will generate mechanical vibrations due to the offset of the rotation axis. These vibrations not only affect the accuracy of the embossing, but also cause the embossed pattern to be repeated or misplaced.

[0003] Therefore, it is necessary to design a paper-drawing four-side embossing device to solve the problems existing in the current technology. Utility Model Content

[0058] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0059] In the description of this application, it should be understood that the terms "center", "up", "down", "front", "front", "left", "right", "vertical", "horizontal", "front", "front", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0060] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. Throughout this application, unless otherwise specified, "plurality" means two or more.

[0061] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0062] See Figure 1-3 As shown, this embodiment provides a four-side embossing device for drawing paper, including: a pressing unit 1, a clamping unit 2, a rolling shaft 9, an embossing roller 11 and an active roller 12, the active roller 12 is sleeved with the rolling shaft 9, the pressing unit 1 includes: a top plate 100, a first telescopic rod 101, a pressing block 102, a pressure sensing module 103 and a stopper 104, one end of the first telescopic rod 101 is fixedly connected to the top plate 100, the other end of the first telescopic rod 101 is fixedly connected to the pressing block 102, the pressing block 102 is attached to the embossing roller 11, the pressure sensing module 103 is sleeved with the pressing block 102, the stopper 104 is fixedly connected to the side surface of the top plate 100, the pressure sensing module 103 is used to monitor the pressure of the embossing roller 11, the clamping unit 2 includes: a clamping plate 200, a first The restraint block 201, the second restraint block 215, the first column 206, the second column 208, the first sliding column 207, the second sliding column 209, the sliding mechanism and the fixed axis mechanism, the splint 200 has several through holes 204, one end of the first column 206 is fixedly connected to the first restraint block 201, the other end of the first column 206 is fixedly connected to the first sliding column 207, one end of the second column 208 is fixedly connected to the second restraint block 215, the other end of the second column 208 is fixedly connected to the second sliding column 209, the first column 206 and the second column 208 are located inside the through hole 204, the sliding mechanism is fixedly connected to the first sliding column 207, the fixed axis mechanism is fixedly connected to the upper surface of the splint 200, and the fixed axis mechanism is used to fix the rolling axis 9.

[0063] Specifically, the embossing roller 11 is in direct contact with the paper towel, and its surface is engraved with a pattern for embossing. During high-speed rotation, the embossing roller 11 forms an embossing pattern by applying specific pressure to the paper towel. The pressing unit 1 is responsible for ensuring that the embossing roller 11 can apply uniform pressure to the paper towel during the embossing process. The top plate 100 is used to support other components to ensure the stability and mechanical strength of the pressing unit 1. The first telescopic rod 101 adjusts the height and pressure of the pressing block 102 through telescopic movement, so that it can be flexibly adjusted according to the thickness of the paper towel and the embossing requirements. The pressing block 102 is connected to the top of the first telescopic rod 101 and acts on the surface of the embossing roller 11. By properly adjusting the height of the pressing block 102, the embossing roller 11 applies uniform pressure to the paper towel, and the paper towel will not be loose and unevenly embossed. The pressure sensing module 103 is mounted on the pressing block 102 and is responsible for real-time monitoring of the pressure applied by the pressing block 102 to the embossing roller 11, ensuring that the pressure is always uniform and avoiding insufficient pressure that results in shallow embossing, or excessive pressure that results in damage to the paper towel. The block 104 is fixed to the side surface of the top plate 100, limiting the displacement range of the pressure sensing module 103 and preventing the embossing roller 11 from vibrating the pressure sensing module 103 and causing displacement under high-speed rotation. The pressing unit 1 presses the embossing roller 11 against the paper towel through the pressing block 102, ensuring that the paper towel remains flat during the embossing process. The pressure sensing module 103 can control the telescopic rod to rise or fall according to the thickness and material of different paper towels, thereby adjusting the pressure to improve the uniformity and quality of the embossing.

[0064] It is understood that the clamping unit 2 is responsible for fixing the rolling shaft 9 to prevent the rolling shaft 9 from generating mechanical vibration due to the deviation of the rotation axis during high-speed rotation. The through holes 204 are preferably three, used to provide a suitable track for the first column 206 and the second column 208. There is one first restraining block 201 and two second restraining blocks 215. The first column 206 and the second column 208 are connected to the first restraining block 201 and the second restraining block 215 respectively. The first sliding column 207 is connected to the sliding mechanism so that the first column 206 can slide freely inside the through hole 204 and can be flexibly adjusted according to needs. The rolling shaft 9 is used to drive the active roller 12 to ensure efficient power transmission during the embossing process. The active roller 12 is used to convey the paper towel. The fixed shaft mechanism fixes the surface of the connecting clamp 200 to prevent the rolling shaft 9 from being displaced or loosened during the embossing process, and to prevent the rolling shaft 9 from shaking or sliding and causing uneven embossing. The clamping unit 1 and the clamping unit 2 work together to avoid embossing deviation of the paper towel.

[0065] See Figure 4As shown, in some examples of the present application, the sliding mechanism includes: a second telescopic rod 211, a first sliding groove 212, a second sliding groove 213, a first sliding rod 205 and a second sliding rod 214, the first sliding groove 212 and the second sliding groove 213 are opened at both ends of the first sliding rod 205, the second telescopic rod 211 is fixedly connected to the back side of the splint 200, the top of the second telescopic rod 211 passes through the interior of the first sliding column 207, the top of the second telescopic rod 211 is fixedly connected to the first nut 216, the first nut 216 slides on the surface of the second sliding groove 213, one end of the second sliding rod 214 is fixedly connected to the second sliding column 209, the other end of the second sliding rod 214 is fixedly connected to the second nut 217, and the second nut 217 slides on the surface of the first sliding groove 212.

[0066] Specifically, the second telescopic rod 211 drives the first sliding column 207 to move through its telescopic function. The top of the second telescopic rod 211 is extended and retracted, causing the first nut 216 to slide on the surface of the second sliding groove 213, thereby driving the first sliding rod 205 to move. The first sliding rod 205 is placed crosswise, and the first sliding rod 205 and the second sliding rod 214 are connected by the second nut 217. The second nut 217 slides on the surface of the first sliding groove 212 of the first sliding rod 205. The cross movement of the first sliding rod 205 causes the second nut 217 to slide, thereby driving the second sliding rod 214 to move, and then moving the second sliding column 209. The second telescopic rod 211 causes the first sliding column 207 and the second sliding column 209 to move sequentially through its telescopic movement, which can effectively adjust the fixation of the rolling shaft 9.

[0067] It can be understood that the movement of the first sliding column 207 and the second sliding column 209 drives the movement of the first restraint block 201 and the second restraint block 215. The first restraint block 201 and the second restraint block 215 can effectively adjust the locking range according to the change of the state of the rolling shaft 9, thereby firmly fixing the rolling shaft 9 to prevent its rotational movement from deviation.

[0068] In some examples of the present application, the sliding mechanism further includes: a limiting block 210 , which is symmetrically distributed on both sides of the first sliding column 207 and the second sliding column 209 .

[0069] It will be appreciated that the symmetrical distribution of the stoppers 210 balances the external forces exerted on the first and second sliding posts 207, 209 during movement, reducing the potential for tilting or shifting of the first and second sliding posts 207, 209 due to asymmetric forces, thereby ensuring smooth sliding. As the first and second sliding posts 207, 209 move along the through-hole 204, the stoppers 210 provide clear displacement boundaries, preventing deviations in the movement of the first and second sliding posts 207, 209. This ensures that the first and second sliding posts 207, 209 slide smoothly along the trajectory of the through-hole 204, preventing lateral swing or shifting.

[0070] In some examples of the present application, the four-side embossing device for drawing paper also includes: a base 14, a first longitudinal beam 4, a second longitudinal beam 5 and a cross beam 13, the bottom of the first longitudinal beam 4 is fixedly connected to the base 14, the bottom of the second longitudinal beam 5 is fixedly connected to the base 14, one end of the cross beam 13 is fixedly connected to the first longitudinal beam 4, the other end of the cross beam 13 is fixedly connected to the second longitudinal beam 5, and the top plate 100 is fixedly connected to the cross beam 13.

[0071] It is understood that the bottoms of the first longitudinal beam 4 and the second longitudinal beam 5 are fixedly connected to the base 14, forming a stable support structure. The crossbeam 13 provides lateral support for the device. The top plate 100 of the compression unit 1 is fixedly mounted on the crossbeam 13, ensuring the stability of the telescopic function of the first telescopic rod 101.

[0072] See Figure 5 As shown, in some examples of the present application, the paper drawing four-side embossing device is further provided with: a distance limiting unit 3, the distance limiting unit 3 includes: a first cylinder 300, a second cylinder 301 and a vertical plate 302, the bottom of the first cylinder 300 is fixedly connected to the first longitudinal beam 4, the bottom of the second cylinder 301 is fixedly connected to the second longitudinal beam 5, the vertical plate 302 is fixedly connected to the top of the first cylinder 300, the vertical plate 302 is fixedly connected to the top of the second cylinder 301, and the vertical plate 302 is attached to the active roller 12.

[0073] It can be understood that the bottom of the first cylinder 300 is fixedly connected to the first longitudinal beam 4, and the bottom of the second cylinder 301 is fixedly connected to the second longitudinal beam 5, which ensures the stability of the operation of the first cylinder 300 and the second cylinder 301. The vertical plate 302 is fixedly connected to the top of the first cylinder 300 and the second cylinder 301 respectively. Through the action of the first cylinder 300 and the second cylinder 301, the vertical plate 302 can flexibly adjust its position and fit the active roller 12. The vertical plate 302 limits the two sides of the paper pulling to prevent the paper towel from offset during transportation, thereby ensuring the accuracy of the paper pulling position during embossing.

[0074] See Figure 6As shown, in some examples of the present application, the four-side embossing device for drawing paper includes: the upper surface of the base 14 is fixedly connected to the motor 15, the upper surface of the motor 15 is fixedly connected to the operating unit 16, the first longitudinal beam 4 has a first groove 6 and a second groove 7, the second longitudinal beam 5 has a positioning groove 8, and the operating unit 16 has an axis groove 19.

[0075] As you can understand, a motor 15 is fixedly mounted on the upper surface of base 14. This motor 15 is the power source for the device, driving various components. It also provides a control interface for operating unit 16, which features a smart screen that allows touch control to adjust the device's operating status. The first groove 6, second groove 7, and positioning groove 8 provide precise positioning. The shaft groove 19 provided in operating unit 16 accommodates the rotating shaft, ensuring stable operation of the device.

[0076] In some examples of the present application, the shaft fixing mechanism includes: a protrusion 202 and a shaft insertion platform 203, the bottom of the shaft insertion platform 203 is fixedly connected to the splint 200, the bottom of the protrusion 202 is fixedly connected to the shaft insertion platform 203, the clamping unit 2 is provided with a third column 20, the third column 20 is fixedly connected to the second longitudinal beam 5, one end of the rolling shaft 9 is connected to the output end of the motor 15, the other end of the rolling shaft 9 is sleeved with the protrusion 202, the rolling shaft 9 is arranged inside the second groove 7, and the active roller 12 is sleeved with the rolling shaft 9.

[0077] Specifically, the shaft inserting platform 203 and the protrusion 202 are used to fix the rolling shaft 9. The shaft inserting platform 203 provides a placement space for the rolling shaft 9. The rolling shaft 9 is sleeved on the surface of the protrusion 202. The protrusion 202 has high wear resistance. The protrusion 202 prevents the rolling shaft 9 from detaching during high-speed rotation. The third column 20 of the clamping unit 2 is fixedly connected to the second longitudinal beam 5, which effectively prevents the clamping unit 2 from falling off. The height of the third column 20 enables the sliding mechanism to slide freely, avoiding the sliding mechanism from getting stuck due to insufficient height.

[0078] It can be understood that the output end of the motor 15 provides power for the rolling shaft 9, and the rolling shaft 9 is precisely installed in the second groove 7 to ensure its stability during rotation. The active roller 12 is sleeved with the rolling shaft 9, and the rolling shaft 9 rotates to drive the active roller 12 to move.

[0079] In some examples of the present application, the four-side embossing device for drawing paper includes: a driven shaft 10 is arranged inside the first groove 6, one end of the driven shaft 10 is inserted into the inside of the shaft groove 19, the other end of the driven shaft 10 is inserted into the inside of the positioning groove 8, and the embossing roller 11 is sleeved on the driven shaft 10.

[0080] It is understood that the driven shaft 10 is precisely mounted in the first groove 6, ensuring smooth rotation. Driven by the driven shaft 10, the embossing roller 11 can rotate smoothly and perform uniform embossing. The shaft groove 19 and the positioning groove 8 ensure that the driven shaft 10 does not move due to the influence of rotation during the embossing operation.

[0081] In some examples of the present application, the four-side embossing device for drawing paper includes: a first gear 17 is provided on the rolling shaft 9, a second gear 18 is provided on the driven shaft 10, and the first gear 17 and the second gear 18 are meshed.

[0082] As can be understood, the meshing of the first gear 17 and the second gear 18 achieves efficient power transmission. Driven by the motor 15, the rolling shaft 9 rotates, driving the first gear 17. The first gear 17, in turn, meshes with the second gear 18, causing the driven shaft 10 to rotate synchronously. This ensures that during the embossing process, the embossing roller 11 and the driving roller 12 work together to maintain a uniform embossing effect and a consistent paper towel conveying rhythm.

[0083] In some examples of the present application, in the four-side embossing device for paper drawing, a zinc layer is provided on the surfaces of the base 14, the first longitudinal beam 4, the second longitudinal beam 5 and the cross beam 13.

[0084] It is understandable that the zinc layer is used to enhance the protective performance of the device. The zinc layer has good anti-corrosion and anti-oxidation properties. The zinc layer can provide additional protection to prevent metal parts from rusting or being damaged, so that the device can maintain good performance after long-term use, ensuring the durability and reliability of the device.

[0085] In summary, the pressure sensing module in the pressing unit can monitor the pressure of the embossing roller in real time, ensure the uniformity of pressure during the embossing process, and avoid poor embossing effect caused by excessive or insufficient pressure. The pressing block can apply appropriate pressure to the embossing roller to ensure the embossing effect on all four sides of the paper towel. The clamping plate, sliding mechanism and fixed shaft mechanism in the clamping unit can stably fix the rolling shaft, improve the stability of the rolling shaft during high-speed rotation, and thus ensure the embossing quality of the paper towel. Through the provision of the first sliding column, the second sliding column and the sliding mechanism, the sliding of the first restraining block and the second restraining block can be flexibly adjusted to further fix the rolling shaft, so that the equipment can adapt to the rolling shaft under the rotation speed, reduce the maintenance process of the device, and improve production efficiency. The coordinated cooperation of the units makes the device take up less space, simple to operate, suitable for various production scenarios, and effectively improves production efficiency and embossing effect.
