Description

Technical Field

[0001] This invention relates to a manufacturing apparatus for producing household paper. Background Technology

[0002] Household paper is widely used in people's daily lives. With the improvement of living standards, people are using more and more household paper products such as kitchen paper. These products usually have a large basis weight and a thicker feel.

[0003] To make tissue paper thicker, tougher, and more comfortable to the touch, technologies such as TAD (hot air penetration drying) have been developed. After years of development, the high energy consumption and other technical drawbacks of this technology have received increasing attention from the industry. Meanwhile, in order to further improve the performance of tissue paper produced by traditional DCT technology, people have combined TAD technology or improved existing DCT technology to develop technologies such as NTT and ATMOS to achieve lower energy consumption and higher paper bulk.

[0004] These devices, such as those shown in CN103890264A and US6743339B1, are used for manufacturing household paper. However, for wiping products like kitchen paper towels, in addition to a thick feel, people also want better wiping effects, that is, a rougher surface. In addition, these types of household paper towels need to have a higher basis weight, such as 30g / m², 40g / m², or even 50g / m² to 70g / m² per layer. However, under such a high basis weight, the dehydration capacity during the pressing process in the existing technology is still insufficient, resulting in greater energy consumption in the later stages. Therefore, an improved technical solution is needed to solve the above technical problems. Summary of the Invention

Detailed Implementation

[0027] Please refer to Figure 1 This invention provides a tissue paper manufacturing apparatus for manufacturing tissue paper webs 404, which have a g / m² content of 10–80 g / m². 2 The basis weight is particularly suitable for manufacturing materials with a basis weight of 30–75 g / m³. 2 For thin paper width 404, a basis weight of 42–55 g / m² is more suitable. 2 Meanwhile, these thin paper webs 404 are creased paper webs formed from cellulose fibers, and these thin paper webs 404 can have a thickness of 100 to 500 μm, or further have a thickness of 150 to 350 μm.

[0028] The aforementioned tissue paper manufacturing equipment includes a forming section 10, a pressing section 20, and a drying section 30.

[0029] The forming section 10 includes a headbox 11, a forming roller 12, a forming net 14, and a first fabric belt 15. The headbox 11 is used to spray the cellulose fiber suspension onto the forming net 14. At least a portion of the forming roller 12 is covered by the first fabric belt 15 and dehydrates the cellulose fiber suspension. The first fabric belt 15 is an endless loop, at least a portion of which covers the forming roller 12 and supports the movement of the wet paper web 401. At least a portion of the forming net 14 is attached to the first fabric belt 15 covering the forming roller 12 to form a clamping area. The partially dehydrated cellulose fiber suspension passes through the clamping area to form the wet paper web 401.

[0030] Understandably, on one side of the clamping area, the forming net 14 and the first fabric belt 15 form a forming area. The headbox 11 includes a plurality of nozzles for spraying cellulose fiber suspension. The nozzles are located in the forming area. The cellulose fiber suspension is sprayed onto the forming net 14. Typically, the position where the cellulose fiber suspension is sprayed onto the forming net 14 is called the landing point. Understandably, the landing point is spaced apart from the clamping area.

[0031] Understandably, the forming net 14 is wound around a plurality of forming rollers and forms an endless loop so that the forming net 14 can circulate. The first fabric belt 15 is wound around a plurality of first rollers and forms an endless loop. The forming rollers include a chest roller 13.

[0032] The pressing section 20 is located downstream of the forming section 10 and includes a pressing assembly 200. The pressing assembly 200 includes a main pressing roller 23, a first pressing roller 21, and a second pressing roller 22. The first pressing roller 21 and the main pressing roller 23 cooperate to form a first pressing zone 210, and the second pressing roller 22 and the main pressing roller 23 cooperate to form a second pressing zone 220. The cooperation allows the first pressing roller 21 and the main pressing roller 23 to apply a first pressure to the wet paper web 401 passing through the first pressing zone 210, and the second pressing roller 22 and the main pressing roller 23 to apply a second pressure to the wet paper web 401 passing through the second pressing zone 220.

[0033] In this embodiment, the first press roller 21, the second press roller 22, and the main press roller 23 are all rollers with a coating layer, which can be a polyurethane coating layer. In other embodiments, the first press roller 21 and the second press roller 22 can also be shoe-type presses. Specifically, the main press roller 23 is a rigid roller or a roller with a coating layer, while the first press roller 21 and the second press roller 22 include a shoe-shaped component, a ring belt sleeved outside the shoe-shaped component, a roller that drives the ring belt, and an application component located inside the shoe-shaped component and applying pressure to the shoe-shaped component.

[0034] The press section 20 also includes a second fabric belt 16 wound around a plurality of idler rollers and a main press roller 23. The second fabric belt 16 passes through the first press zone 210 and the second press zone 220 and transfers the press paper web 402 formed after passing through the first press zone 210 and the second press zone 220 to the downstream direction.

[0035] Understandably, the second fabric strip 16 is also in the form of an endless loop so that it can be circulated.

[0036] Understandably, the first fabric belt 15 also passes through the first press zone 210 and the second press zone 220, and the first fabric belt 15 and the second fabric belt 16 form a clamping shape for the wet paper web 401 in the area between the first press zone 210, the second press zone 220, and the area between the first press zone 210 and the second press zone 220. For ease of description, the area between the first press zone 210 and the second press zone 220, clamped by the first fabric belt 15 and the second fabric belt 16, is referred to as the intermediate press zone 240. Understandably, the wet paper web 401 is subjected to pressure and dewatering in the first press zone 210, the second press zone 220, and the intermediate press zone 240. Specifically, in the first press zone 210, the first press roll 21 applies a first pressure to the main press roll 23, squeezing the water on the wet paper web 401 to form dewatering. In the second press zone 220, the second press roll 22 applies pressure to the main press roll 23. The main press roll 23 applies a second pressure to squeeze the water on the wet paper web 401, resulting in dewatering. In the intermediate press zone 240, pressure is applied by the first fabric belt 15 and the second fabric belt 16 to further dewater the paper. Typically, the second pressure is set higher than the first pressure to achieve a better dewatering effect, especially for high-basic-weight and high-thickness paper sheets, creating a tiered dewatering effect. Studies have found that after passing through the first press zone 210, the fibers are compacted. However, due to the reduced pressure in the intermediate press zone 240, the fibers rebound, increasing the gaps between them. Then, the wet paper web 401 is squeezed again in the second press zone 220 to achieve dewatering. Under this action, the wet paper web 401 forms a squeeze-rebound-squeeze action, which can improve the dewatering efficiency by an average of 5.2% compared to the conventional NTT press method, especially for high-basic-weight paper sheets, such as 42 g / m³. 2 The above-mentioned 404 thin paper width can improve the dehydration efficiency by an average of 7.7%.

[0037] Furthermore, the first pressure can be greater than or equal to 330 KN / m, and the second pressure can be greater than or equal to 450 KN / m. In a preferred embodiment, the first pressure is 350 to 420 KN / m and the second pressure is 500 to 550 KN / m. In this case, compared with the high pressure of more than 600 KN / m used in traditional single pressure application, the above setting method can reduce the occurrence of crushing or dead lines on the paper.

[0038] Furthermore, the dryness of the wet paper web 401 is 15-30%, and the dryness of the press paper web 402 is 45-70%. Furthermore, after passing through the first press zone 210, the dryness of the wet paper web 401 is 25-40%, and after passing through the second press zone 220, the press paper web 402 is formed.

[0039] Furthermore, the upstream of the first press zone 210 includes a front idler roller 151, and the first fabric belt 15 is wound around the front idler roller 151. The first fabric belt 15 includes a first press section between the first press zone 210 and the front idler roller 151. The angle between the first press section and the second fabric belt 16 is 18-32°. At the same time, the downstream of the second press zone 220, the first fabric belt 15 includes a second press section. The angle between the second press section and the second fabric belt is also 18-32°. This allows the wet paper web to easily enter the first press zone 210 and allows the pressed paper web to easily separate from the first fabric belt 15 and move with the second fabric belt 16.

[0040] Furthermore, the main press roller 23 includes a rigid sidewall 230 and an accommodating space 2300 enclosed by the rigid sidewall 230. The rigid sidewall 230 includes a plurality of through holes 231 penetrating the thickness direction of the rigid sidewall 230. At the same time, the rigid sidewall 230 can rotate around its axis under the drive of the driving device. A first adsorption box 233 is provided in the accommodating space 2300. The first adsorption box 233 includes an adsorption chamber. The adsorption chamber includes a first adsorption port 2331. The first adsorption port 2331 is correspondingly provided with the intermediate press zone 240 to make the intermediate press zone 240 a negative pressure state. It can be understood that the adsorption chamber is connected to a negative pressure device. In this case, when the wet paper web 401 is in the intermediate press zone 240, it forms a dewatering effect under the action of negative pressure.

[0041] Furthermore, the accommodating space 2300 also includes a first inner air box 232 corresponding to the first pressing zone 210. The first inner air box 232 is configured to blow airflow toward the first pressing zone 210 to further assist in dehydration during the pressing process.

[0042] Furthermore, the first inner air box 232 blows hot airflow into the first pressing zone 210. At the same time, an adsorption device is provided inside the first pressing roller 21 to allow the extracted water to be discharged from the adsorption device inside the first pressing roller 21 to the outside of the pressing assembly 200.

[0043] Understandably, the airflow blown out by the first inner air box 232 is from the direction of the self-pressing roller 23 to the direction of the first press roller 21. This airflow plays three roles here: firstly, it helps with dewatering; secondly, it enables the wet paper web 401 to remain attached to the first fabric belt 15 in the first press zone 210 and move with the first fabric belt 15; and thirdly, since the first fabric belt 15 usually has a greater thickness and the second fabric belt 16 is provided with small holes 161, the hot airflow can directly act on the wet paper web 401 through the second fabric belt 16, thereby achieving better dewatering and drying effects.

[0044] Please refer to this as well. Figure 3 The second fabric strip 16 includes a base portion 160, on which a plurality of small holes 161 are provided. It can be understood that the small holes 161 serve two purposes in practice: firstly, to allow the airflow blown out by the first inner bellows 232 to directly act on the wet paper web 401.

[0045] Furthermore, the water removed from the wet paper web 401 can enter the first adsorption box 233 through the small hole 161 and be discharged from the first adsorption box 233. Secondly, the small hole 161 makes the wet paper web 401 form a rougher surface.

[0046] Understandably, the aperture of the small hole 161 is less than or equal to 1 mm, so as to avoid crushing in some areas of the surface of the wet paper web 401 during the pressing process.

[0047] Furthermore, the accommodating space 2300 also includes a second adsorption box 234 corresponding to the second pressing zone 220. The second adsorption box 234 includes a second adsorption port, which is correspondingly arranged with the second pressing zone 220, thus creating a negative pressure state in the second pressing zone 220 to aid in dehydration. That is, in the second pressing zone 220, the airflow direction is from the second pressing zone 220 towards the second adsorption box 234, meaning that the airflow direction at this location is the same as the airflow direction at the first pressing zone 210. The opposite direction allows the airflow to serve two purposes: firstly, to help remove moisture from the wet paper web 401; and secondly, to facilitate the transfer of the press paper web 402 from moving with the first fabric belt 15 to moving onto the second fabric belt 16 with the assistance of the airflow. That is, the second fabric belt 16 does not need to be made as smooth as in the prior art. Even with a rough surface on the second fabric belt 16, the press paper web 402 can still separate from the first fabric belt 15 and adhere to the second fabric belt 16, moving with the second fabric belt 16.

[0048] Furthermore, the press assembly 200 also includes an external air box 24 corresponding to the intermediate press zone 240. The external air box 24 includes an air outlet facing the intermediate press zone 240. The air outlet is configured to blow hot air towards the intermediate press zone 240 to further improve the dryness of the pressed paper web 402.

[0049] Furthermore, the second press roll 22 also includes a press air box 221 disposed within the second press roll 22. The press air box 221 includes an air outlet facing the second press zone 220 and is configured to blow airflow into the second press zone 220 to further aid dewatering and to separate the press paper web from the first fabric belt 15.

[0050] Please refer to this as well. Figure 4 In the second embodiment, the pressing assembly includes an intermediate pressing device corresponding to the intermediate pressing zone 540. The intermediate pressing device includes a plurality of third pressing rollers 541 and a pressing belt 542 wound around the plurality of third pressing rollers 541. The pressing belt 542 includes an intermediate region that abuts against the intermediate pressing zone 540. The third pressing rollers 541 are configured to apply a third pressure to the first fabric belt in the intermediate region, thereby making the intermediate pressing zone 540 have a larger pressing area, thus forming a better dehydration effect.

[0051] Furthermore, the pressing belt 542 is a steel belt.

[0052] Furthermore, the pressing belt 542 is provided with several ventilation holes.

[0053] Furthermore, the third pressure is less than the first and second pressures.

[0054] Furthermore, the forming section 10 is also provided with several auxiliary dewatering devices. Typically, the auxiliary dewatering devices can be vacuum dewatering rollers or vacuum dewatering boxes. More specifically, the vacuum dewatering box has an adsorption space connected to a negative pressure device. The adsorption space includes an adsorption port adjacent to and facing the first fabric belt 15. Water in the first fabric belt 15 and the wet paper web 401 is adsorbed, collected, and discharged through the adsorption port, thereby increasing the dryness of the wet paper web 401 before entering the first pressing zone 210.

[0055] Furthermore, a heating device may be provided in the press section 20. The heating device is configured to increase the dryness of the paper web 402 by passing a hot air stream through it. The hot air stream may be a high-temperature steam stream or a hot air stream.

[0056] Furthermore, the heating device includes a hot airflow box and an adsorption box opposite to the hot airflow box. The hot airflow box and the adsorption box are respectively located on the outer side of the press paper web 402 and the inner side of the second fabric belt 16. The hot airflow box includes an airflow opening, and the adsorption box includes an adsorption port. The hot airflow passes through the airflow opening, passes through the press paper web 402 and the second fabric belt 16, and flows to the adsorption port. In this case, on the one hand, the dryness of the press paper web 402 can be further improved, and the energy consumption of the subsequent drying section 30 can be reduced. On the other hand, the press paper web 402 can be kept attached to the second fabric belt 16 and run. It is understood that the heating device is located in the downstream direction of the press assembly 200.

[0057] The drying section 30 includes a drying cylinder 31 for drying the press paper web 402 to form a dry paper web 403 and a scraper 33 for wrinkling the dry paper web 403 to form a thin paper web 404.

[0058] Understandably, the drying cylinder 31 includes an outer drying surface for attaching and drying the pressed paper web 402, and the pressing section 20 includes a transfer roller for attaching the second fabric belt 16 to the outer drying surface. The transfer roller applies pressure to the drying cylinder 31 to form a pressing zone, and the pressed paper web 402 is attached and transferred to the outer drying surface after passing through the pressing zone.

[0059] Understandably, the transfer roller is located inside the second fabric belt 16 so that the outer side of the second fabric belt 16 adheres to the outer drying surface, thereby transferring the press paper web 402 to the outer drying surface.

[0060] Furthermore, in order to facilitate the easy transfer of the press paper web 402 to the outer drying surface, the outer drying surface has a smooth surface. Additionally, an adhesive material such as a roller adhesive can be sprayed onto the outer drying surface.

[0061] The scraper 33 is disposed downstream of the drying process, and at least one part of the scraper 33 remains attached to the outer drying surface, so that the formed dried paper web 403 impacts the scraper 33 to form wrinkles, and finally forms a thin paper web 404 with wrinkles.

[0062] The scraper 33 can be made of steel, cemented carbide or hard ceramic material, and there is no limitation.

[0063] In addition, an air hood 32 is provided outside the drying cylinder 31, and a medium for drying the press paper web 402, such as high-temperature steam or hot air, is introduced into the air hood 32.

[0064] Furthermore, the first fabric belt 15 and the second fabric belt 16 operate at the same speed.

[0065] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
