Description

Technical Field

[0001] The invention relates to the technical field of paper towel processing, and more specifically, to an embossing device and an embossing process for paper towel processing. Background Art

[0002] Paper towels need to be embossed during the processing. On the one hand, embossing can make the paper more compact. The multiple layers of paper are formed into a structure similar to mortise and tenon joints through embossing. The concave and convex surfaces are nested with each other and are not easy to separate naturally. On the other hand, it can enhance water absorption. Embossing makes the surface of paper towels uneven, forming multiple small spaces, which are more conducive to absorbing and storing water. Embossing can also increase friction and fluffiness. The embossed paper surface is rougher, which can increase friction and adhesion and enhance the cleaning effect. At the same time, air will gather in the unpressed areas to form small bubbles, which increases the fluffiness and makes it softer and more comfortable to use. In addition, embossing can also make paper towels have a sense of relief, enhance the three-dimensional sense and artistry, and better highlight the brand characteristics.

[0003] As market demand changes, the number of layers of each paper towel increases. Paper towels with more layers have stronger water absorption and durability, can absorb liquid quickly and are not easy to break. At the same time, they are softer and more comfortable, and are gentler on the skin when used. The thick feel and high-end feel also enhance the quality of the product. In addition, multi-layer paper towels have excellent cleaning ability, can effectively remove stains and reduce paper scraps. At the same time, they may reduce usage due to better performance, and have environmental benefits.

[0004] Paper towel embossing is mainly achieved through a metal roller with a pattern. A flat paper is placed on the metal roller and the pattern on the roller is transferred to the paper by squeezing the paper surface. However, most existing embossing devices are only suitable for embossing conventional three-layer or four-layer paper towels. When embossing more layers of paper towels, the thickness and hardness of the paper towels increase, which will first accelerate the wear of the embossing roller. Secondly, the equipment will be in a high-load operation state for a long time, resulting in accelerated wear of other key components and shortened service life. Summary of the invention

[0036] Referring to Figures 1 to 6 , in an embodiment of the present application, an embossing device for paper towel processing includes a base 1 and an embossing mechanism;

[0037] A first raw material roller 2 and a second raw material roller 3 are rotatably connected to the base 1. A first paper tape 201 is wound around the first raw material roller 2, and a second paper tape 301 is wound around the second raw material roller 3. A first support roller 4, a turning roller 5, and a second support roller 6 are rotatably connected to the base 1. A bridge 7 is fixedly connected to the base 1, and a pressure roller 8 is rotatably connected to the bridge 7;

[0038] Two embossing mechanisms are symmetrically provided. Both of the two embossing mechanisms are arranged on the bridge 7. The two embossing mechanisms are respectively arranged on both sides of the pressure roller 8, and the two embossing mechanisms are used for embossing the first paper tape 201 and the second paper tape 301;

[0039] One end of the first paper tape 201 away from the first raw material roller 2 sequentially bypasses the first support roller 4 and the turning roller 5. The first support roller 4 supports the first paper tape 201. One end of the second paper tape 301 away from the second raw material roller 3 bypasses the second support roller 6. The second support roller 6 supports the second paper tape 301. The first paper tape 201 passes through between an embossing mechanism and the pressure roller 8. The first paper tape 201 and the second paper tape 301 pass through between another embossing mechanism and the pressure roller 8;

[0040] As Figure 1 and Figure 2 , the first paper tape 201 passes through between the pressure roller 8 and the embossing mechanism below. The embossing mechanism applies pressure towards the pressure roller 8, thereby embossing the first paper tape 201 for the first time. The second paper tape 301 and the first paper tape 201 after the first embossing jointly pass through between the pressure roller 8 and the embossing mechanism above. The second paper tape 301 is located above the first paper tape 201. The second paper tape 301 contacts the embossing mechanism above, thereby embossing the first paper tape 201 and the second paper tape 301 for the second time;

[0041] When both the first paper tape 201 and the second paper tape 301 are three-layer, the embossing mechanism below embosses the three-layer first paper tape 201. The embossing mechanism above only needs to apply the pressure for embossing four-layer paper towels, and it can emboss three layers in the second paper tape 301 and one layer in the first paper tape 201, thereby completing the embossing of six-layer paper towels and the first paper tape 201 and the second paper tape 301 becoming an integral whole. Since the two embossing mechanisms only need to emboss three-layer or four-layer paper towels respectively, the wear of each component can be effectively reduced and the service life can be extended.

[0042] As a preferred embodiment of the present application, each embossing mechanism includes an embossing roller 9, a movable seat 10, a fixed seat 11, an electric cylinder 12, and a motor 13. The embossing roller 9 is arranged on one side of the pressure roller 8. Both ends of the embossing roller 9 are respectively rotatably connected to the movable seat 10. The embossing roller 9 is supported by the two movable seats 10. One side of each of the two movable seats 10 is respectively provided with a fixed seat 11. Both of the two fixed seats 11 are fixedly connected to the bridge 7. Electric cylinders 12 are respectively installed on the two fixed seats 11. The piston rods of the two electric cylinders 12 are respectively fixedly connected to the two movable seats 10. One end of the embossing roller 9 is connected to the output shaft of the motor 13 through a coupling. The motor 13 is installed on the adjacent movable seat 10;

[0043] As Figure 4 , by simultaneously driving the two movable seats 10 to move through the two electric cylinders 12, the two movable seats 10 can drive the embossing roller 9 to move towards the pressure roller 8. Then, by driving the embossing roller 9 to rotate through the motor 13, embossing can be performed;

[0044] In practical applications, the electric cylinder 12 can also be replaced by other linear driving members, which is not limited in this embodiment.

[0045] As a preferred embodiment of the present application, guide rods 14 are respectively and fixedly connected to the two movable seats 10, and the two guide rods 14 are respectively slidably connected to the two fixed seats 11;

[0046] Such as Figure 4 , the guide rod 14 can make the movable seat 10 more stable during the movement process.

[0047] As a preferred embodiment of the present application, a plurality of sliding grooves 15 are formed in the embossing roller 9, a plurality of embossing sleeves 16 are sleeved on the embossing roller 9, a plurality of clamping strips 17 are fixedly connected to each embossing sleeve 16, and the plurality of clamping strips 17 are respectively slidably connected to the plurality of sliding grooves 15. A T-shaped groove 18 is formed in the embossing roller 9, a plurality of T-shaped plates 19 are slidably connected in the T-shaped groove 18, and the plurality of T-shaped plates 19 are respectively fixedly connected to the plurality of embossing sleeves 16. Two ends of each T-shaped plate 19 are respectively fixedly connected with a screw rod 20, and a nut 21 is threadedly connected to each screw rod 20;

[0048] Such as Figure 6 , the plurality of clamping strips 17 on the embossing sleeve 16 are respectively slidably connected to the plurality of sliding grooves 15, and the embossing roller 9 drives the embossing sleeve 16 to rotate through the plurality of clamping strips 17; loosen the nut 21, and the embossing sleeve 16 can move on the embossing roller 9, so as to adjust the position of the embossing sleeve 16, and further adjust the embossing position. Then tighten the nut 21, and the position of the embossing sleeve 16 can be fixed;

[0049] When a certain embossing sleeve 16 is worn, it can be replaced separately without replacing the entire embossing roller 9, which is beneficial to cost saving.

[0050] As a preferred embodiment of the present application, each embossing mechanism further includes a cleaning cover 22, a brush roller 23 and a transmission assembly. Two ends of the cleaning cover 22 are respectively fixedly connected to the two movable seats 10, a brush roller 23 is rotatably connected to the cleaning cover 22, and the brush roller 23 is in frictional contact with the plurality of embossing sleeves 16;

[0051] The transmission assembly is connected to one end of the brush roller 23, and the transmission assembly is used to drive the brush roller 23 to rotate. Such as Figure 4 , the rotating brush roller 23 can clean the plurality of embossing sleeves 16, so as to ensure the embossing effect.

[0052] As a preferred embodiment of the present application, the transmission assembly includes a first synchronous pulley 24, a synchronous belt 25, and a second synchronous pulley 26. The first synchronous pulley 24 is fixedly connected to one end of the brush roller 23. The first synchronous pulley 24 is drivingly connected to the second synchronous pulley 26 through the synchronous belt 25. The second synchronous pulley 26 is fixedly connected to one end of the embossing roller 9.

[0053] As Figure 5 , the embossing roller 9 can drive the second synchronous pulley 26 to rotate. The second synchronous pulley 26 drives the first synchronous pulley 24 to rotate through the synchronous belt 25. The first synchronous pulley 24 can then drive the brush roller 23 to rotate. Moreover, the diameter of the second synchronous pulley 26 is larger than that of the first synchronous pulley 24, so that the rotational speed of the brush roller 23 is faster than that of the embossing roller 9, and the cleaning effect is better.

[0054] As a preferred embodiment of the present application, a dust suction cover 27 is communicated with the cleaning cover 22. A dust suction pipe 28 is communicated with the dust suction cover 27. One end of the dust suction pipe 28 away from the dust suction cover 27 is communicated with the air inlet of a blower 29. A filter screen is installed at the air inlet of the blower 29. The blower 29 is installed on a fixed seat 11.

[0055] As Figure 4 , the blower 29 can extract the impurities cleaned by the brush roller 23 in the cleaning cover 22 through the dust suction pipe 28 and the dust suction cover 27, and these impurities will be filtered and intercepted by the filter screen at the air inlet of the blower 29, so as to collect these impurities.

[0056] In another embodiment of the present application, an embossing process for tissue paper processing is also proposed, including the following steps:

[0057] S1: One end of the first paper tape 201 away from the first raw material roller 2 bypasses the first support roller 4 and then passes through between an embossing mechanism and the pressure roller 8 to perform the first embossing on the first paper tape 201.

[0058] S2: After the first embossing, the first paper tape 201 bypasses the turning roller 5 and then passes through between another embossing mechanism and the pressure roller 8.

[0059] S3: One end of the second paper tape 301 away from the second raw material roller 3 bypasses the second support roller 6 and then passes through between another embossing mechanism and the pressure roller 8 together with the first paper tape 201 to perform the second embossing on the first paper tape 201 and the second paper tape 301.

[0060] Working principle: The first paper tape 201 passes through between the pressure roller 8 and the embossing mechanism below. The embossing mechanism applies pressure towards the pressure roller 8, thereby performing the first embossing on the first paper tape 201. The second paper tape 301 and the first paper tape 201 after the first embossing jointly pass through between the pressure roller 8 and the embossing mechanism above. The second paper tape 301 is located above the first paper tape 201 and contacts the embossing mechanism above, thereby performing the second embossing on the first paper tape 201 and the second paper tape 301;

[0061] When both the first paper tape 201 and the second paper tape 301 are three - layer, the embossing mechanism below embosses the three - layer first paper tape 201. The embossing mechanism above only needs to apply the pressure for embossing four - layer paper towels, and then it can emboss three layers in the second paper tape 301 and one layer in the first paper tape 201, thereby completing the embossing of six - layer paper towels and the first paper tape 201 and the second paper tape 301 become an integral whole.

[0062] The above - mentioned is only the preferred implementation mode of the present invention. The protection scope of the present invention is not limited to the above - mentioned embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.

[0063] In addition, it should be understood that although this specification is described according to the implementation modes, not every implementation mode only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
