Description

Technical Field

[0001] The invention relates to the technical field of noodle paper production, in particular to a method for producing noodle paper. Background Art

[0002] Liner paper is a high-strength industrial paper used to make cardboard or corrugated board. Due to its tough texture and high burst resistance, it is often used as the middle or bottom layer of multi-layer cardboard. It is primarily used in the packaging industry, especially for transport packaging of heavy products such as home appliances, electronics, and machinery. The production process of liner paper mainly involves the crushing, purification, pulping, papermaking, pressing, drying, and winding of waste paper or virgin wood pulp. It is then formed using a Fourdrinier or rotary paper machine and subjected to high-temperature hot pressing to enhance its strength and stability. Pressing, in the papermaking process, refers to the process of passing the pulp between a series of pressing rollers to mechanically remove moisture from the wet paper sheets.

[0003] However, there are still the following problems in the pulp squeezing and dehydration process:

[0004] 1. The traditional pulp dewatering process mainly relies on the circumferential rolling action of a single pressure roller. The limitation of this method is that it is difficult to effectively deal with the complex moisture distribution inside the pulp, resulting in a slow and uneven dewatering process. In addition, the distribution uniformity of pulp fibers in the width direction of the conveyor belt is poor, the bonding strength between fibers is insufficient, and the pressure distribution in the pressing area is not optimized. This not only easily causes damage to the pulp fibers, but also causes a large amount of residual moisture inside the pulp, resulting in low dewatering efficiency, which in turn affects the dryness and molding quality of the final product.

[0005] 2. In addition, the local water film structure in the pulp is difficult to destroy, and the dehydration channel is blocked, which further limits the improvement of the dehydration effect. At the same time, traditional methods are prone to material deposition or uneven distribution when processing pulp, which not only affects the uniformity and forming effect of the pulp, but may also cause internal blockage of the equipment and increase the maintenance frequency. These problems together lead to low production efficiency and unstable product quality. Summary of the Invention

[0017] The present invention has the following beneficial effects:

[0018] (1) The production method of noodle paper is to set an axial squeezing assembly that can move back and forth along the axial direction of the pressing roller, and apply multi-directional and continuous squeezing force to the pulp along the transmission direction of the pulp on the pulp conveyor belt and in the direction perpendicular to the transmission direction, so as to achieve efficient squeezing and dewatering. This squeezing method is different from the traditional dewatering form that only relies on the circumferential rolling of the pressing roller. On the basis of maintaining the original dewatering effect, it can further improve the distribution uniformity of pulp fibers in the width direction of the conveyor belt, enhance the bonding strength between fibers, and improve the dewatering efficiency and molding quality. By introducing the axial force, it not only optimizes the pressure distribution in the pressing area, but also helps to reduce the residual moisture inside the pulp.

[0019] (2) The production method of noodle paper is to set a knocking rod and a knocking ball to knock the inner wall of the pressing roller at a high frequency, so as to cleverly transfer the vibration energy generated during the knocking process to the pulp conveyor belt through the pressing roller, and further act on the forming pulp between the inner and outer pulp conveyor belts. This structure not only effectively intervenes in the pulp deposition or uneven distribution problems that may exist inside the pressing roller, but also promotes the uniform dispersion of fibers through vibration, improves the spreading uniformity of the pulp in the width direction of the conveyor belt, and at the same time, the vibration force helps to destroy the local water film structure in the pulp, improve the dehydration channel, and thus enhance the dehydration efficiency and forming density.

[0020] (3) In the production method of the noodle paper, pressure rollers are evenly arranged on the outside of the fixed cylinder. This arrangement not only effectively reduces the overall footprint of the device and makes the structure more compact, but also provides a more uniform and dense pressure action area during the pulp dewatering process, thereby improving the dewatering efficiency of the pulp. In addition, under the action of the inverted V-shaped guide plate and the pressure plate, the dewatered water is uniformly guided into the fixed cylinder, which not only improves the dewatering efficiency, but also effectively avoids problems such as water retention and secondary pollution.

[0021] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The following is based on Figures 1-15 The present invention describes a method for producing noodle paper provided by an embodiment of the present invention.

[0039] Embodiment one:

[0040] See also Figure 1 The production method of the noodle paper comprises the following steps:

[0041] Step 1: The fiber raw material that has been cooked and lignin and hemicellulose removed is mechanically treated and dispersed into pulp to form the raw pulp of noodle paper.

[0042] Step 2: Spray the raw pulp in step 1 onto the pulp conveyor belt 5, and use a pressing device to squeeze and remove water from it to form pressed-dried paper.

[0043] Step 3: Dry the squeezed paper after dehydration to form noodle paper.

[0044] In step 2, extrusion and dehydration are performed by applying extrusion forces in at least two directions, wherein the extrusion forces in the two directions are along the conveying direction of the pulp on the pulp conveyor belt 5 and in a direction perpendicular to the conveying direction.

[0045] Also, see Figures 1-6 The pressing device in step 2 includes a fixed cylinder 1, which is installed on a fixed platform 2. A plurality of pressing rollers 3 are evenly arranged on the outside of the fixed cylinder 1. The pressing rollers 3 can rotate around their own axes. When the pressing rollers 3 rotate, they can cooperate with the stationary fixed cylinder 1 to apply uniform pressure to the pulp passing between the two, thereby achieving effective squeezing and dehydration of the pulp in the transmission direction of the pulp conveyor belt 5. This arrangement not only effectively reduces the overall footprint of the device and makes the structure more compact, but also provides a more uniform and intensive pressure action area during the pulp dehydration process, thereby improving the dehydration efficiency of the pulp.

[0046] The outer sides of adjacent pressing rollers 3 are provided with rotating rollers 4, and the pressing rollers 3 and rotating rollers 4 are rotatably mounted on the fixed platform 2. A slurry conveying belt 5 is wound around the pressing roller 3 and the rotating roller 4, and the rotating roller 4 can actively rotate to support, guide and transmit the slurry conveying belt 5. The slurry conveying belt 5 adopts an inner and outer double-layer structure design, wherein the slurry conveying belt 5 located on the outer side is made of rubber material, which is elastic and waterproof. A supporting roller for supporting the outer slurry conveying belt 5 is rotatably mounted on the fixed platform 2, and the outer slurry conveying belt 5 can be circulated around the pressing roller 3, the rotating roller 4 and the supporting roller; the slurry conveying belt 5 located on the inner side is made of polyester fiber mesh, which is conducive to pulp dehydration and forming. The inner slurry conveying belt 5 is driven and guided by the existing conveying unit. The original slurry in step one can be sprayed onto the inner conveying belt and, driven by the conveying unit, is conveyed to the forming area formed by the inner and outer slurry conveying belts 5, and the dehydration and forming operation is carried out under the cooperation of the pressing roller 3 and the fixed cylinder 1.

[0047] See also Figure 4 、 Figure 8 and Figure 10In order to squeeze the pulp in a direction perpendicular to the transmission direction of the pulp conveyor belt 5, an axial squeezing assembly is also provided on the inner side of the pressing roller 3. The axial squeezing assembly includes squeezing balls 31 evenly distributed along the axial direction of the pressing roller 3. The squeezing balls 31 are rotatably mounted on the mounting frame 312 via the rotating shaft 311. The mounting frame 312 can drive the squeezing balls 31 to move back and forth along the axial direction of the pressing roller 3. The squeezing balls 31 can rotate around the rotating shaft 311. At the same time, balls are rolled on the outer side of the squeezing balls 31. The balls are in rolling contact with the inner wall of the pressing roller 3. When the squeezing balls 31 move back and forth along the axial direction of the rotating pressing roller 3, the balls can effectively reduce the friction resistance between the two.

[0048] It should be noted that the pressing roller 3 is made of a flexible material with certain elasticity and deformation ability, and can produce controllable local compression deformation when it is acted upon by the squeezing ball 31. When the squeezing ball 31 moves back and forth axially along the pressing roller 3, the pressing roller 3 can transmit the axial pressure it receives to the pulp conveyor belt 5, and perform uniform axial squeezing on the pulp located between the inner and outer pulp conveyor belts 5. This axial squeezing method is different from the traditional dewatering method that only relies on the circumferential rolling of the pressing roller. On the basis of maintaining the original dewatering effect, it can further improve the uniformity of the distribution of pulp fibers in the width direction of the conveyor belt, enhance the bonding strength between fibers, and improve the dewatering efficiency and molding quality. By introducing the axial force, it not only optimizes the pressure distribution in the pressing area, but also helps to reduce the residual moisture inside the pulp.

[0049] Also, see Figure 4 、 Figure 8 and Figure 10When the cam 314 is in the closed position, the cam 316 is in the closed position, and the cam 317 is in the closed position, so the cam 316 is in the closed position, and the cam 317 is in the closed position, so the cam 316 is in the closed position, and the cam 317 is in the closed position, so the cam 317 is in the closed position, and the cam 317 is in the closed position, so the cam 317 is in the closed position, and the cam 317 is in the closed position, so the cam 317 is in the closed position, and the cam 317 is in the closed position, so the cam 317 is in the closed position, and the cam 317 is in the closed position, so the cam 317 is in the closed position, and the cam 317 is in the closed position, so the cam 317 is in the closed position, The rod 313 moves synchronously therewith, and the knocking ball 314 slides back and forth in the annular groove 315 and continuously knocks the inner wall of the pressing roller 3. Through this high-frequency knocking, the vibration generated can be transmitted to the pulp conveyor belt 5 via the pressing roller 3, and further act on the forming pulp between the inner and outer pulp conveyor belts 5. This structure not only effectively intervenes in the pulp deposition or uneven distribution problems that may exist inside the pressing roller 3, but also promotes the uniform dispersion of fibers through vibration, and improves the spreading uniformity of the pulp in the width direction of the conveyor belt. At the same time, the vibration force helps to destroy the local water film structure in the pulp, improve the dehydration channel, and thus enhance the dehydration efficiency and forming density.

[0050] The elastic telescopic rod 316 is hinged between the left and right opposite knocking rods 313, and the elastic telescopic rod 316 is used to enhance the linkage and overall stability of the knocking rod 313 during movement. When the knocking ball 314 slides back and forth in the annular groove 315 on the inner wall of the pressure roller 3, the knocking rod 313 may produce a slight swing due to structural gap or uneven force. At this time, the elastic telescopic rod 316 can be appropriately stretched or compressed according to the actual displacement, thereby absorbing the offset and improving the stability of the knocking rod 313 during movement. At the same time, an elastic telescopic column 317 is installed on the fixed section of the elastic telescopic rod 316, and its telescopic end extends toward the inner wall of the pressure roller 3 and maintains a contact state. As the knocking rod 313 drives the elastic telescopic rod 316 along the axial direction of the pressure roller 3 During the reciprocating motion, the elastic telescopic column 317 also moves synchronously, and its telescopic end continuously slides through the annular groove 315. Since the elastic telescopic column 317 has a certain elastic deformation ability, it can adaptively adjust the contact depth according to the contour of the annular groove 315, thereby enhancing the vibration transmission effect and making the vibration force generated inside the pressing roller 3 more uniform and continuous. In addition, the squeezing ball 31, the knocking ball 314 and the elastic telescopic column 317 together form a multi-point contact support structure with the inner wall of the pressing roller 3, which not only improves the structural rigidity and dynamic stability of the axial extrusion component during operation, but also helps to more effectively transmit mechanical vibration to the pulp conveyor belt 5 and the pulp material in the forming area, thereby further optimizing the fiber distribution, improving the dehydration efficiency and the forming quality.

[0051] Also, see Figures 8-10 When the cam 312 is in the closed position, the cam 312 is in the closed position, and the cam 312 is in the open position, so that the cam 312 can slide smoothly along the cam 312 axis when the cam 312 is in the closed position.

[0052] See also Figure 2 、 Figure 5 、 Figure 6 、 Figure 8 and Figure 11 In order to make the axial extrusion assembly move back and forth along the axial direction of the pressure roller 3, connecting columns 321 are installed at the front and rear ends of the mounting frame 312, and rotating columns 322 are installed at the front and rear ends of the pressure roller 3. An annular wedge-shaped groove 323 is provided in the rotating column 322 to slide with the connecting column 321. When the pressure roller 3 rotates, the rotating column 322 rotates synchronously therewith. The annular wedge groove 323 continuously slides relative to the connecting column 321 during its rotation. Since the profile of the annular wedge groove changes periodically, the connecting column 321 will produce axial displacement as the groove shape changes when sliding in the groove, thereby driving the mounting frame 312 and the axial extrusion assembly as a whole to reciprocate along the axial direction of the pressure roller 3.

[0053] Also, see Figure 2 、 Figure 5-Figure 9 and Figure 12The cam 324 is connected to the support frame 312 by the spring 326, and the spring 327 is connected to the support frame 312 by the spring 327. The cam 326 is connected to the support frame 312 by the spring 326. The sliding guiding function of the rectangular rod 326 and the extension rod 324 provides a stable moving path for the mounting bracket 312, thereby improving the accuracy and stability of the overall operation. A reset spring 327 is connected between the other end of the extension rod 324 and the rotating column 322, which is sleeved on its outer side to form an elastic reset structure. When the mounting bracket 312 reciprocates in the axial direction of the pressure roller 3 with the axial extrusion assembly, the extension rod 324 moves synchronously along the rotating column 322 and compresses or releases the reset spring 327 according to the movement state, thereby enhancing the automatic reset ability of the axial extrusion assembly after each reciprocating stroke.

[0054] Also, see Figure 8 and Figure 9 The cam 328 is a kind of cam which is used to move the roller 314 in the direction of the rotation of the roller 3 so that the roller 314 can move relative to the roller 314 when the roller 314 is in the direction of rotation.

[0055] See also Figure 2 、 Figure 5 、 Figure 6 and Figure 8In order to achieve the synchronous driving of the axial extrusion assembly in the mounting sleeve 328, a rotating column 2 329 is rotatably installed at the front and rear ends of the mounting sleeve 328. The rotating column 1 322 and the rotating column 2 329 are connected by a belt 1 330. When the rotating column 1 322 and the pressure roller 3 rotate, the power is transmitted to the rotating column 2 329 via the belt 1 330, driving them to rotate synchronously. Since the mounting sleeve 328 itself is fixed, the rotation of the rotating column 2 329 is only used to drive the axial extrusion assembly inside it to reciprocate along the axis direction of the mounting sleeve 328. In addition, through reasonable structural design, the axial extrusion assembly in the mounting sleeve 328 and the axial extrusion assembly in the pressure roller 3 maintain synchronous but opposite reciprocating motions during the movement, thereby achieving staggered pressure and improving the uniformity of pulp fiber distribution and dehydration efficiency.

[0056] See also Figure 3 、 Figure 5 、 Figure 13 and Figure 14 The dewatering plate 332 is provided on the outer side of the inverted V-shaped deflector 331, and the dewatering plate 332 is connected to the cavity of the inverted V-shaped deflector 331. The dewatering plate 332 is in contact with the bottom of the inner pulp conveyor belt 5, exerting a certain pressure on it, so that the water in the pulp is further squeezed out under the pressure.

[0057] See also Figure 1 、 Figure 2 、 Figure 13 and Figure 14 The water squeezed out from the slurry conveyor belt 5 flows into the interior of the fixed cylinder 1 after passing through the cavity of the pressure plate 332 and the cavity of the inverted V-shaped guide plate 331 in turn. An upwardly protruding arc structure is provided in the middle of the bottom inner wall of the fixed cylinder 1, and the front and rear sides are inclined downward to form a drainage area, which is convenient for the water to flow forward and backward along the protrusions. The front and rear ends of the fixed cylinder 1 are respectively connected with a pumping pipe 6, and the other end of the pumping pipe 6 is connected to the water collecting box 7, thereby realizing the continuous extraction and centralized collection of the dewatered water. This water collection method not only realizes the reasonable guidance of the dehydration path and improves the dehydration efficiency, but also effectively avoids problems such as water retention and secondary pollution.

[0058] Also, see Figure 6and Figure 7 The adjusting block 412 can slide along the fixed platform 2 through the spring rod 413, so that the rotating roller 4 can move in a small range to adaptively support the slurry conveyor belt 5, thereby avoiding excessive or insufficient force on the slurry conveyor belt 5 and affecting the pulp forming effect.

[0059] Please refer to Figure 2 、 Figure 5 and Figure 6 In order to achieve synchronous rotation of the pressure roller 3 and the rotating roller 4, pulleys 334 are installed at the front end of the transmission shaft 411 and the rotating column 1 322. The pulleys 334 are connected to each other through the belt 2 335. One of the pulleys 334 is connected to the output shaft of the driving motor 336 as the active pulley 334. The position of the pulley 334 is fixed and does not have the adaptive movement function. When in use, the driving motor 336 can be started first, the active pulley 334 rotates and drives the remaining pulleys 334 to operate synchronously through the belt 2 335. The transmission shaft 411, the rotating column 1 322 and the rotating column 2 329 respectively drive the rotating roller 4 and the pressure roller 3 to rotate synchronously. At the same time, the pressure roller 3 and the axial extrusion assembly in the mounting sleeve 328 also enter a reciprocating motion state, realizing continuous axial pressure dehydration of the pulp.

[0060] Example 2:

[0061] See also Figure 15 The difference between this embodiment and the first embodiment is that a fixing block 337 is installed on the mounting frame 312 here, and the squeezing ball 31 is rollingly mounted on the fixing block 337. When the mounting frame 312 drives the squeezing ball 31 to move back and forth along the axial direction of the pressure roller 3, since the squeezing ball 31 has universal rotation ability, it can roll synchronously with the rotation of the pressure roller 3, thereby effectively avoiding sliding friction between the two and reducing operating resistance. This not only reduces the wear between the squeezing ball 31 and the pressure roller 3, and ensures the smooth operation of the axial squeezing component, but also helps to maintain the uniformity and stability of the pressure applied to the pressure roller 3, further improving the pulp dehydration and forming quality.
