Description

Technical Field

[0001] The present invention relates to the technical field of high-strength tissue paper processing, and specifically to a method for processing high-strength tissue paper. Background Art

[0002] High-strength tissue paper is a special tissue paper product with high tear resistance, good flexibility and high wet strength. Compared with ordinary tissue paper, high-strength tissue paper can provide higher durability while maintaining a soft touch, and is not easy to break. It is especially suitable for high-end household tissue paper, industrial wiping paper, kitchen tissue paper and other scenarios. Its excellent performance mainly benefits from optimized fiber ratio, enhanced papermaking process, and subsequent calendering and wrinkling treatments. During its production process, the tissue paper goes through multiple key steps such as fiber optimization, staged beating, composite papermaking, vacuum dewatering, crosslinking curing, and gradient drying, and finally forms a product with excellent strength and softness.

[0003] During the forming and winding process of the tissue paper, the doctor blade is one of the key equipment. It clings to the surface of the drying cylinder, shovels up the tissue paper, and forms fine wrinkle structures on the surface of the tissue paper, making it more fluffy and soft; during the process of scraping the tissue paper, the doctor blade continuously rubs against the paper sheet, causing some fibers to break and form paper dust. These paper dusts will gradually accumulate on the surface of the doctor blade. Since the traditional wrinkling doctor blade only has the function of scraping the tissue paper and does not have an automatic cleaning function, as the working time increases, the paper dust will accumulate thicker and thicker, resulting in the doctor blade slipping, making the wrinkling effect uneven. Insufficient wrinkling in some parts of the tissue paper will also cause the hand feeling to become hard, affecting the final quality of the tissue paper.

[0004] Therefore, during the production process, it is necessary to regularly clean the paper dust on the doctor blade, but each time the doctor blade is cleaned, the machine needs to be stopped, which will also affect the continuity and stability of the tissue paper production line. Summary of the Invention

[0005] The present invention provides a method for processing high-strength tissue paper, which solves the technical problems that the traditional wrinkling doctor blade only has a scraping function and lacks automatic cleaning ability. After long-term operation, the paper dust accumulates, causing the doctor blade to slip, the wrinkling to be uneven, making some parts of the tissue paper hard, affecting the final quality, and frequent machine stops are required to clean the paper dust, which destroys the continuity and stability of the production line.

[0006] The method for processing high-strength tissue paper provided by the present invention is as follows:

[0007] S1. Mixing ratio of raw materials: Use long fiber base materials to provide skeleton strength, short fibers to improve softness, add bamboo pulp or flax fiber to increase tear strength, and then add wet strength agents, dry strength agents and softening agents as functional additives to improve the performance of the tissue paper.

[0008] S2. Fiber pretreatment and beating: Use a hydrapulper to fully disperse the fibers, improve fiber separation, and ensure the uniformity of the pulp. Then, successively perform fibrillation of the fibers by low-consistency beating of the raw materials to increase the specific surface area of the fibers, and high-consistency beating to further longitudinally split the fibers, improve fiber bonding force, and enhance the toughness of the tissue paper.

[0009] S3. Multi-layer composite papermaking: During the multi-layer composite papermaking process, the pulp is optimally configured according to the different functional requirements of the outer layer, middle layer, and inner layer. The outer layer uses long fibers and bamboo pulp to make the fibers oriented, thereby enhancing wear resistance and toughness. The middle layer is mainly composed of short fibers and a wet strength agent is added to ensure that the tissue paper has good water absorption and wet strength. The inner layer adds an appropriate amount of long fibers and a dry strength agent to improve the overall structural strength and tear resistance. After papermaking is completed, the tissue paper is dehydrated in stages by a vacuum dewatering process to effectively reduce fiber loss and improve the uniformity and stability of the formed paper.

[0010] S4. Curing and drying: Spray a 0.5% glyoxal solution on the surface of the wet paper sheet to form more covalent bonds between the fibers. Then, first perform hot air drying of the tissue paper at 120 - 140 °C to quickly evaporate the moisture and fix the high-temperature setting of the fiber network. Then, slowly dry it with hot air at 80 - 100 °C to reduce the shrinkage stress, avoid embrittlement of the tissue paper due to rapid drying, and improve the softness.

[0011] S5. Surface treatment: Use a double-roll calender to calender at 60 - 80 °C and a line pressure of 50 - 80 kN / m to make the surface of the tissue paper smoother. Form fine wrinkles in the longitudinal direction of the tissue paper through a wrinkling blade to increase the elongation rate, make the tissue paper fluffy and soft. Finally, spray 0.2% cream to improve the touch, enhance the skin-friendly property, and enhance the moisturizing effect.

[0012] The processing method steps of the high-strength tissue paper in the above S1 - S5 steps need to be completed in cooperation with a tool rest, a wrinkling blade, a self-cleaning mechanism, and a blowing mechanism.

A dust collection mechanism for collecting the cleaned paper dust is jointly arranged between the left part of the outer wall of the tool rest and the two automatic cleaning mechanisms. A dust sweeping mechanism for further cleaning the paper dust attached to the upper surface of the wrinkling scraper is arranged on the upper automatic cleaning mechanism.

[0014] In a possible implementation manner, the dust collection mechanism includes a tube fixedly connected to the tool rest through a connecting rod. A collection cylinder is detachably installed at the lower part of the tube. A fixing plate is fixedly connected to the upper part of the inner cavity of the tube. An electric telescopic rod is fixedly connected to the lower end face of the fixing plate.

[0016] In a possible implementation manner, the blowing mechanism includes a main pipeline fixedly connected to the tool rest through a support rod. The left end of the main pipeline is communicated with two branch pipes corresponding to the tracheas. The left end of the branch pipe is connected to the right end of the trachea.

[0017] In a possible implementation manner, a rectangular fixing frame is fixedly connected to the upper part of the inner cavity of the tube. A dust suppression net is fixedly connected in the rectangular fixing frame. A filter cloth is fixedly connected to the lower end face of the fixing frame.

[0024] In the present invention, through the mutual combination of the self-cleaning mechanism and the dust-sweeping mechanism, the paper dust falling on the surface of the wrinkling blade during the wrinkling process is automatically sucked away and cleaned in real time, ensuring the sharpness of the wrinkling blade, avoiding the situation that the wrinkling blade slips due to paper dust, ensuring that uniform and delicate wrinkles are formed on the surface of the tissue paper, improving the fluffiness and softness, and thus improving the processing quality of the tissue paper.

[0025] In the present invention, the self-cleaning mechanism and the dust-sweeping mechanism are combined and run in real time when operating with the wrinkling blade, avoiding affecting the production progress due to frequent shutdowns for cleaning the blade, and improving the continuity and stability of the production line.

[0026] In the present invention, through the dust collection mechanism, the collected paper dust is concentrated together, preventing the paper dust from spreading in the air, and the loose paper dust can be compressed into blocks, improving the storage density, reducing the occupation of storage space.

[0037] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0038] Please refer to Figure 1 and Figure 2 , the present invention provides a technical solution: a method for processing high-strength paper towels. The specific steps of the method for processing high-strength paper towels are as follows:

[0039] S1. Raw material mixing ratio: Use long fiber substrates to provide skeletal strength, short fibers to enhance softness, add bamboo pulp or linen fibers to increase tear strength, and then add wet strength agents, dry strength agents, and softening agents as functional additives to improve the performance of the paper towels.

[0040] S2. Fiber pretreatment and beating: Use a hydrapulper to fully disperse the fibers, improve fiber separation, and ensure the uniformity of the pulp. Then, perform low-consistency beating on the raw materials in sequence to fibrillationize the fibers, increase the specific surface area of the fibers, and perform high-consistency beating to further longitudinally split the fibers, improve fiber bonding, and enhance the toughness of the paper towels.

[0041] S3. Multi-layer composite papermaking: Optimize the configuration of the pulp according to the different functional requirements of the outer layer, middle layer, and inner layer. The outer layer uses long fibers and bamboo pulp to make the fibers oriented, thereby enhancing wear resistance and toughness. The middle layer is mainly composed of short fibers and adds wet strength agents to ensure that the paper towels have good water absorption and wet strength. The inner layer adds an appropriate amount of long fibers and dry strength agents to improve the overall structural strength and tear resistance. After papermaking is completed, the paper towels are dewatered in stages under pressure through a vacuum dewatering process, effectively reducing fiber loss and improving the uniformity and stability of the formed paper.

[0042] S4. Curing and drying: Spray a 0.5% glyoxal solution on the surface of the wet paper sheet to form more covalent bonds between the fibers. Then, first perform hot air drying on the paper towels at 120 - 140 °C to quickly evaporate the moisture and fix the fiber network through high-temperature shaping. Then, slowly dry with hot air at 80 - 100 °C to reduce the shrinkage stress, avoid embrittlement of the paper towels due to rapid drying, and improve softness.

[0043] S5. Surface treatment: Use a double-roll calender to calender at 60 - 80 °C and a line pressure of 50 - 80 kN / m to make the surface of the paper towels smoother. Form fine wrinkles in the longitudinal direction of the paper towels through a wrinkling knife 2 to increase the elongation rate, make the paper towels fluffy and soft. Finally, spray 0.2% cream glycerol + aloe extract to improve the touch, enhance skin-friendliness, and enhance the moisturizing effect.

[0044] The processing method steps of the high-strength paper towels in the above S1 - S5 steps need to be completed in cooperation with a tool rest 1, a wrinkling knife 2, a self-cleaning mechanism 3, and a blowing mechanism 4.

[0045] The wrinkling knife 2 is detachably installed on the tool rest 1, and a self-cleaning mechanism 3 for timely sucking and cleaning the paper dust generated during the wrinkling process of the paper towels is arranged on the upper part of the tool rest 1 and attached to the outer wall of the wrinkling knife 2.

[0046] Please refer to Figure 2 、 Figure 4 and Figure 5, in this embodiment, the self-cleaning mechanism 3 includes a strip-shaped box 31 fixedly connected to the tool rest 1 through a fixing rod and having an opening fitting on the upper surface of the wrinkling blade 2. A strip-shaped through groove 32 for paper dust to enter is formed on the front wall plate of the strip-shaped box 31 near the side of the wrinkling blade 2. A trachea 33 is fixedly connected to the side of the strip-shaped box 31 away from the wrinkling blade 2. A number of communicating grooves 34 communicating with the trachea 33 are equidistantly formed on the side wall plate of the strip-shaped box 31 away from the wrinkling blade 2. The lower part of the tool rest 1 is also provided with the same self-cleaning mechanism 3. A blowing mechanism 4 is provided on the right part of the tool rest 1 for communicating with the two tracheas 33 to make the strip-shaped box 31 form a negative pressure and then suck the paper dust into the trachea 33. A dust collecting mechanism 5 for collecting the cleaned paper dust is jointly provided on the left part of the outer wall of the tool rest 1 and the two self-cleaning mechanisms 3. The dust collecting mechanism 5 includes a tube 51 fixedly connected to the tool rest 1 through a connecting rod. A receiving plate 9 is fixedly connected to the front end surface of the strip-shaped box 31 at the lower part. The receiving plate 9 is in an inclined state with the side close to the strip-shaped box 31 being lower and the side away from the strip-shaped box 31 being higher. An input pipe 7 is jointly communicated between the strip-shaped box 31 and the tube 51. An input pipe 8 is jointly communicated between the trachea 33 and the tube 51.

[0047] Please refer to Figure 3 , the blowing mechanism 4 includes a main pipe 41 fixedly connected to the tool rest 1 through a support rod. Two branch pipes 42 corresponding to the tracheas 33 are communicated with the left end of the main pipe 41. The left end of the branch pipe 42 is connected to the right end of the trachea 33. An air pump 43 (the motor of the air pump 43 is not shown in the drawings) is communicated with the right part of the main pipe 41.

[0048] The wrinkling blade 2 is attached to the surface of the rolled-out tissue paper. The rolled-out and moving tissue paper generates wrinkles on the blade surface of the wrinkling blade 2. The paper dust generated during the wrinkling process falls on and drops from the surface of the wrinkling blade 2. Specifically, the paper dust located below the wrinkling blade 2 will fall downward onto the receiving plate 9, and then roll into the strip-shaped box 31 through the strip-shaped through groove 32 along the inclined surface of the receiving plate 9, and then enter the lower trachea 33 through the communicating groove 34.

[0049] The paper dust located above the wrinkling blade 2 will adhere to the upper surface of the wrinkling blade 2, and then roll into the strip-shaped box 31 through the strip-shaped through groove 32 under the inclined surface of the wrinkling blade 2. Control the air pump 43 to operate, and the driving motor drives the fan blade to rotate and blow air into the main pipe 41. Then the air flow enters the trachea 33 through the branch pipe 42. The air flow then flows in the trachea 33 from right to left. According to the principle that the pressure is low where the fluid velocity is high, a negative pressure is generated at the communicating groove 34. The communicating groove 34 then sucks air into the interior of the strip-shaped box 31, thereby sucking the paper dust in the strip-shaped through groove 32 into the trachea 33. The paper dust then moves leftward under the action of the air flow in the trachea 33, and finally enters the tube 51 through the input pipe 8. Then the dust collecting mechanism 5 can be controlled to operate to collect and process the paper dust entering itself.

[0050] The airflow in the main pipe 41 also flows into the lower trachea 33 through the branch pipe 42 located at the lower part. Then, following the same steps above, the airflow in the lower trachea 33 drives the paper dust entering the trachea 33 to enter the tube 51 through the second input pipe 8.

[0051] Please refer to Figure 2 and Figure 7 In this embodiment, the dust collection mechanism 5 further includes a collection cylinder 52. The collection cylinder 52 is detachably installed at the lower part of the tube 51. An upper fixing plate is fixedly connected to the upper part of the inner cavity of the tube 51. An electric telescopic rod 53 is fixedly connected to the lower end face of the fixing plate. A pressing plate 54 slidably connected in the tube 51 is fixedly connected to the lower end of the electric telescopic rod 53. Arc-shaped grooves 55 are formed in the front and rear cavity walls of the tube 51. A rectangular fixing frame is fixedly connected to the upper part of the inner cavity of the tube 51. A dust suppression net 56 is fixedly connected in the rectangular fixing frame. A filter cloth is fixedly connected to the lower end face of the fixing frame. Two guiding plates 57 are symmetrically and fixedly connected to the front and rear of the upper end face of the pressing plate 54. Both of the two guiding plates 57 are in an inclined state with the side close to the electric telescopic rod 53 being higher and the side far from the electric telescopic rod 53 being lower.

[0052] The initial position of the pressing plate 54 is located at the middle position of the arc-shaped groove 55. At this time, the area in the inner cavity of the tube 51 and below the pressing plate 54 is connected to the outside through the gap between the pressing plate 54 and the arc-shaped groove 55. The electric telescopic rod 53 is intermittently controlled to extend and contract. The paper dust enters the tube 51 through the trachea 33, and then rolls into the collection cylinder 52. The airflow entering the tube 51 will move upward and finally be discharged upward from the arc-shaped groove 55. At the same time, the airflow passes through the double filtration of the dust suppression net 56 and the filter screen to ensure that the paper dust mixed in the airflow is intercepted. The electric telescopic rod 53 is controlled to extend to drive the pressing plate 54 to move downward. The pressing plate 54 then moves downward into the collection cylinder 52 to compress the paper dust in the collection cylinder 52. After the pressing plate 54 compacts the paper dust, the electric telescopic rod 53 is controlled to contract to drive the pressing plate 54 to move upward. The pressing plate 54 then moves upward into the tube 51 and is higher than the left port height of the upper second input pipe 8, so that the paper dust in the trachea 33 can smoothly enter the tube 51.

[0053] When the pressing plate 54 moves downward to the position inside the collecting cylinder 52, the paper dust in the air pipe 33 will still enter the tube 51. At this time, the paper dust that enters the tube 51 will fall onto the upper end surface of the guiding plate 57. The air flow that enters the tube 51 will flow upward directly, and then be discharged successively through the filter cloth and the dust suppression net 56. The filter cloth and the dust suppression net 56 intercept the paper dust in the air flow. Then, the paper dust rolls along the inclined surface of the guiding plate 57 in the direction opposite to the electric telescopic rod 53 and finally rolls between the guiding plate 57 and the inner cavity of the tube 51. When the pressing plate 54 moves upward, it drives the guiding plate 57 to move at the same time. When the pressing plate 54 moves upward to the position flush with the arc-shaped groove 55, the paper dust accumulated between the guiding plate 57 and the inner wall of the tube 51 falls downward from the arc-shaped groove 55, and then falls into the collecting cylinder 52. After the collecting cylinder 52 has collected paper dust for a period of time, the electric telescopic rod 53 can be controlled again to extend and drive the pressing plate 54 to move downward, repeating the above steps to make the pressing plate 54 compact the paper dust in the collecting cylinder 52 again.

[0054] After the collecting cylinder 52 has collected the paper dust, the collecting cylinder 52 can be removed from the tube 51, and the compressed paper dust can be taken out as a whole for easy disposal.

[0055] Please refer to Figure 2 、 Figure 4 and Figure 6 In this embodiment, on the self-cleaning mechanism 3 located in the upper part, there is a dust sweeping mechanism 6 for further cleaning the paper dust attached to the upper surface of the wrinkling scraper 2. The dust sweeping mechanism 6 includes an electric slider 61 slidably connected to the front end surface of the air pipe 33. The lower end surface of the electric slider 61 is fixedly connected with a T-shaped rod 62. The lower end surface of the transverse section of the T-shaped rod 62 and located inside the strip-shaped box 31 is rotatably connected with a turntable 63. A plurality of cleaning brushes 64 are circumferentially and equidistantly fixedly connected to the lower part of the turntable 63. A transmission component 65 is jointly arranged between the turntable 63 and the strip-shaped box 31. A secondary brush component 66 cooperating with the cleaning brushes 64 is arranged on the transverse section of the T-shaped rod 62. The transmission component 65 includes a rack 651 fixedly connected to the rear cavity wall of the strip-shaped box 31. A gear ring 652 meshing with the rack 651 is fixedly connected to the outside of the turntable 63. The secondary brush component 66 includes a support 661 fixedly connected to the front end surface of the T-shaped rod 62 and with a lower opening. A sliding plate 662 is slidably connected in the support 661. A top spring is jointly fixedly connected between the sliding plate 662 and the support 661. The lower end surface of the sliding plate 662 is fixedly connected with a secondary brush plate 663, and the secondary brush plate 663 is an isosceles trapezoid with a narrow side close to the turntable 63 and a wide side far from the turntable 63.

[0056] Use the top spring to push the slide plate 662 downward. Then, the slide plate 662 pushes the auxiliary brush plate 663 to fit on the surface of the wrinkling scraper 2. While the air pump 43 blows air into the air pipe 33, control the operation of the dust sweeping mechanism 6. Specifically: control the electric slider 61 to reciprocate horizontally. The electric slider 61 then drives the T-shaped rod 62 to move synchronously. The T-shaped rod 62 then drives the turntable 63 to reciprocate horizontally. The turntable 63 then drives the gear ring 652 to move horizontally. During the horizontal movement of the gear ring 652, it interacts with the rack 651 and then rotates. The gear ring 652 then drives the turntable 63 to rotate. The turntable 63 then drives the cleaning brush 64 to rotate. The cleaning brush 64 sweeps the paper dust that is not sucked away by the air pipe 33. The swept paper dust is more convenient to be sucked into the air pipe 33 through the communication groove 34.

[0057] While the T-shaped rod 62 reciprocates horizontally, it also drives the support 661 to move. The support 661 then drives the auxiliary brush plate 663 to move through the slide plate 662. The auxiliary brush plate 663 then sweeps and cleans the surface of the wrinkling scraper 2. The paper dust cleaned is then squeezed and moved towards the rear under the inclined surface of the auxiliary brush plate 663 and pushed into the path where the cleaning brush moves, so that the paper dust generated during the operation of the wrinkling scraper 2 can be completely cleaned.
