Description

Technical Field

[0001] The present invention relates to the technical field of cashmere paper production, and specifically to a production method of cashmere paper. Background Art

[0002] Cashmere paper is a special kind of paper that imitates the touch of cashmere (also called wool paper), and has the following characteristics: super soft texture, high fiber content, usually containing plant fibers and animal fibers; low-gloss matte surface, similar to the natural texture of cashmere fabric. High ink absorption, suitable for high-end printing, packaging, art paper and other fields.

[0003] For example, a wool paper proposed in the patent with the publication number CN101666055B is formed by co-papermaking after mixing plant fibers and animal fibers. However, although it is clean and flat, it cannot simulate the feel of cashmere. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a production method of cashmere paper, which solves the problem that the feel of cashmere cannot be simulated in the prior art.

[0005] To achieve the above objectives, the present invention is realized through the following technical solutions: A production method of cashmere paper, comprising the following steps:

[0006] Step 1: Mix plant fibers and animal fibers to make a raw material slurry, and use a headbox to send the slurry into a papermaking device for papermaking, and then dry it to obtain cashmere paper;

[0007] Step 2: Send the cashmere paper into a carbon brush device, and use the carbon brush assembly in the carbon brush device to brush the surface of the cashmere paper, so that the fibers on the surface of the cashmere paper stand up to simulate cashmere fluff;

[0008] Step 3: Blow air on the cashmere paper obtained in Step 2 to make the fibers standing on the surface of the cashmere paper fluffy.

[0009] Further, in Step 3, a blower is used to blow air on the cashmere paper twice, and the two blowing directions are opposite.

[0010] Further, during the brushing process in Step 2, the part of the carbon hairs of the carbon brush assembly in contact with the cashmere paper is in a dense state, and the carbon hairs can form an open state after leaving the cashmere paper, and a negative pressure pipe is used to suck the carbon hairs in the open state.

[0011] Further, the carbon brush assembly further includes a head seat that can rotate actively, and a carrier strip for carrying carbon hairs is provided in the area near the outer edge of the head seat. The carrier strip is rotatably installed on the head seat through a carrier shaft, so that the angles of the respective carrier strips relative to the circumferential surface of the head seat can change.

[0012] Further, an end shaft is fixedly provided at the end of the carrier shaft, and an adjustment head is sleeved on the end shaft. The adjustment head includes:

[0013] A first disk, on one side of the first disk close to the center of the end seat, inner fins are provided;

[0014] A second disk, on one side of the second disk far from the center of the end seat, outer fins are provided. The first disk and the second disk are fixedly connected;

[0015] The carbon brush assembly further includes an outer carrier ring and an inner carrier plate located on the side of the end seat far from the carrier strip. On the upper part of the inner side of the outer carrier ring, outer resistance fins are evenly arranged. The radial coincidence length of the outer resistance fins and the outer fins increases in a gradient along the rotation direction of the end seat; on the outer surface of the inner carrier plate, an inner resistance fin is provided, and the adjustment head can be pushed when passing through the inner resistance fin.

[0016] Further, the negative pressure pipe is located outside the circular structure formed by the carbon hairs, and the position of the negative pressure pipe is opposite to the area where the inner resistance fin and the outer resistance fin meet.

[0017] Further, a limiting ridge is arranged on the outer peripheral surface of the end shaft along the axial direction, and a groove adapted to the limiting ridge is provided on the inner wall of the adjustment head, so that the adjustment head can slide on the end shaft without affecting co-rotation.

[0018] Further, one side of the adjustment head close to the end seat is provided as a limiting post, a limiting groove adapted to the limiting post is opened on the end seat, and a spring is installed on one side of the limiting post close to the end seat;

[0019] One side of the adjustment head far from the end seat has a force-receiving cover;

[0020] The carbon brush assembly further includes a pressure ring. The lower part of one side of the pressure ring close to the force-receiving cover is provided as a pressure part, and the upper part is provided as a non-pressure part. When the end seat rotates and drives the adjustment head to pass through the pressure part, the pressure part can push the force-receiving cover, so that the limiting post enters the limiting groove, so as to limit the rotation of the end shaft through the adjustment head.

[0021] Further, the carbon brush assembly further includes a fixing seat, and the pressure ring, the first disk and the second disk are all installed on the fixing seat, so that the pressure ring, the first disk and the second disk are in a static state relative to the end seat.

[0022] Further, a partition board is provided on the outer peripheral surface of the end seat, and the partition board is used to block the wool debris generated when blocking the brush hairs from entering the outer surface of the adjustment head.

[0023] The present invention has the following beneficial effects:

[0024] (1). In the production method of the cashmere paper, by setting, the fibers on the surface of the cashmere paper stand up, simulating cashmere fluff, and due to the blowing effect, the fluffiness of the fibers can be ensured, and the tactile comfort is improved.

[0025] (2) Carbon hairs that can open at a certain angle, enabling the negative pressure tube to align with the opening angle for dust suction, thereby effectively removing the lint hidden inside the dense carbon hairs and avoiding the strong electrostatic situation caused by the accumulation of lint inside the carbon hairs.

[0026] (3) In the production method of this cashmere paper, when the cashmere paper passes from left to right below the carbon hairs, the carbon brush assembly should rotate clockwise. The a area below it is the dense state of the carbon hairs. The extension line of the carrier strip in this area should be located on the diameter of the end seat. The angle and orientation of the carbon hairs in this area are the same as those of the bristles in the prior art. As the carbon brush assembly rotates clockwise, the carrier strip reaching the b area deflects, making the carbon hairs in the b area denser, thereby reserving space for the carbon hairs to open in the c area. There is a certain included angle between the two groups of carbon hairs in the c area, so that the negative pressure tube is used to suck dust in this area, enabling the lint hidden inside the carbon hairs to be cleaned, ensuring the continuous operation of the carbon hairs and reducing the danger brought by static electricity.

[0027] (4) In the production method of this cashmere paper, by setting a locking device, the end shaft can be kept in a non-rotating state when in the a area, thereby avoiding the deflection of the end shaft and carbon hairs in the a area, ensuring the correct angle of the carbon hairs against the bristles of the cashmere paper in the a area, and improving the stability during brushing.

[0028] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0047] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0048] In the description of the present invention, it should be understood that the terms "open hole", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0049] The following is based on Figures 1 - 17 Describe a production method of cashmere paper provided by an embodiment of the present invention.

[0050] Please refer to Figure 1 , an embodiment of the present invention provides a production method of cashmere paper, including the following steps:

[0051] A production method of cashmere paper, including the following steps:

[0052] Step 1: Mix plant fibers and animal fibers to make a raw material slurry, and use a headbox to send the slurry into a paper-making device for papermaking and drying to obtain cashmere paper;

[0053] Step 2: Send the cashmere paper into a carbon brush device, and use the carbon brush assembly 400 in the carbon brush device to brush the surface of the cashmere paper, so that the fibers on the surface of the cashmere paper stand up to simulate cashmere fluff;

[0054] Step 3: Blow air on the cashmere paper obtained in Step 2 to make the fibers standing up on the surface of the cashmere paper fluffy.

[0055] Therefore, the production method of cashmere paper provided by the embodiment of the present invention can make the fibers on the surface of the cashmere paper stand up to simulate cashmere fluff, and due to the blowing effect, the fluffiness of the fibers can be ensured, and the tactile comfort can be improved.

[0056] Preferably, the above-mentioned plant fibers are any one or a mixture of any combination of hemp pulp, cotton pulp, wood pulp or waste paper pulp. The animal fiber is wool fiber, and the wool fiber can be refined wool, raw wool or wool spinning waste. The mixing ratio of plant fiber and animal fiber is: plant fiber accounts for 55-90%, and animal fiber accounts for 10%-45%.

[0057] Preferably, in Step 3, a blower is used to blow air on the cashmere paper twice, and the directions of the two blows are opposite. No matter which direction is perpendicular to the cashmere paper, it only needs to keep the directions of the two blows opposite.

[0058] Preferably, during the brushing process in Step 2, the part of the carbon hair 4 of the carbon brush assembly 400 in contact with the cashmere paper is in a dense state, and the carbon hair 4 can form an open state after leaving the cashmere paper, and a negative pressure pipe 300 is used to suck the carbon hair 4 in the open state.

[0059] Therefore, the method for producing cashmere paper provided by the embodiment of the present invention can effectively remove hair scraps hidden in the dense carbon hair 4, thereby avoiding the situation of strong static electricity caused by the accumulation of hair scraps in the carbon hair 4.

[0060] Combination Figure 2 , the carbon brush equipment mentioned above is as follows Figure 1 As shown, its main components are a feeding roller 100, a guide roller 200, a carbon brush assembly 400 and a combing plate which are arranged in sequence. In step one, the dried cashmere paper is fed into the guide roller 200 through the feeding roller 100, and the cashmere paper guided by the guide roller 200 reaches the bottom of the carbon brush assembly 400. As the carbon brush assembly 400 rotates, its carbon hairs 4 can brush the cashmere paper, so that the fibers on the surface of the cashmere paper stand up, simulating cashmere fluff.

[0061] Preferably, a spreading roller 600 is further provided below the carbon brush assembly 400. The spreading roller 600 is located below the carbon brush assembly 400 and is used to laterally spread the cashmere paper passing through the carbon brush assembly 400, thereby increasing the force on the cashmere paper in the width direction and ensuring the brushing effect.

[0062] Combination Figures 3 - 5 As shown, in order to achieve the above-mentioned purpose of allowing the carbon bristles 4 to form two states, either open or dense, the specific operation is as follows: the carbon brush assembly 400 includes two end seats 3 arranged side by side, and the area near the outer edge of the end seat 3 is provided with a carrier bar 7 for supporting the carbon bristles 4. The multiple carrier bars 7 form an axially hollow cylindrical structure, and the two end seats 3 are formed into an integral structure. The carrier bars 7 here are rotatably mounted on the end seat 3 through a carrier shaft 71, so that each carrier bar 7 has a certain angle of rotational freedom, and then the angle of the carbon bristles 4 on the carrier bar 7 relative to the circumferential surface of the end seat 3 can be changed.

[0063] It should be noted that the density of carbon wool 4 is not Figure 3 and Figure 4 The circles of state presented in the Figure 3 and Figure 4 The carbon hair 4 is partially implanted in the carrier strip 7 to make the picture clearer. In fact, the carbon hair 4 is fully distributed on each carrier strip 7. Figure 6 Status shown.

[0064] Reference Figure 7 As shown, it should be noted that when the cashmere paper passes under the carbon hair 4 from left to right, the carbon brush assembly 400 should rotate clockwise, and the area a below is a dense state of carbon hair 4. The extension line of the carrier strip 7 in this area should be located on the diameter of the end seat 3, and the carbon hair 4 in this area is also the same as the angle and orientation of the bristles in the prior art; as the carbon brush assembly 400 rotates clockwise, the carrier strip 7 that reaches the b area deflects, and the specific deflection direction is as shown in FIG. Figure 7As shown, the carbon hairs 4 in area b are deflected downward, making them denser, thereby reserving space for the carbon hairs 4 in area c to open. There is a certain angle between the two groups of carbon hairs 4 in area c, so that the negative pressure tube 300 is used to vacuum the area, so that the hair debris hidden inside the carbon hairs 4 can be cleaned.

[0065] Specifically, the negative pressure tube 300 is located outside the circular structure formed by the carbon wool 4. Figure 2 .

[0066] Preferably, a connector 31 is provided at the center of the circle on the side opposite to each other of the two end seats 3, and a main shaft 10 is assembled on the connector 31. One of the main shafts 10 should be driven by a motor so that the main shaft 10 drives the connector 31 to rotate, thereby realizing the rotation of the end seat 3, thereby forming a rotating state of the entire carbon brush assembly 400.

[0067] Combination Figures 8 - 10 As shown, in order to achieve the purpose of forming the above-mentioned carbon hair 4 in a dense state in area a, in a more dense state in area b, and in an open state in area c, an end shaft 72 is fixedly provided at the end of the carrier shaft 71, and the carrier shaft 71 is rotatably mounted on the end seat 3. The end shaft 72 is located on the side of the end seat 3 away from the carrier strip 7. An adjustment head 9 is sleeved on the end shaft 72. The adjustment head 9 is used as a force-bearing component to control the angle of the carbon hair 4. When the adjustment head 9 rotates a certain angle, it can drive the carrier shaft 71 to rotate a certain angle, so that the angle of the carrier strip 7 and the carbon hair 4 can be changed. Conversely, when the adjustment head 9 is locked so as not to be able to rotate, the angles of the carrier shaft 71, the carrier strip 7 and the carbon hair 4 cannot be changed.

[0068] Combination Figures 10 - 12 As shown, the specific adjustment head 9 includes a first disk 91 and a second disk 92, which are axially fixed to each other. The first disk 91 is provided with an inner wing 911 on the side close to the center of the end seat 3, and the second disk 92 is provided with an outer wing 921 on the side away from the center of the end seat 3. The above-mentioned carbon brush assembly 400 also includes an outer carrier ring 61 and an inner carrier plate 62 located on the side of the end seat 3 away from the carrier strip 7. The outer carrier ring 61 and the inner carrier plate 62 are not assembled on the end seat 3, and the two are in a relatively static state with the end seat 3. When the carbon brush assembly 400 rotates, the outer carrier ring 61 and the inner carrier plate 62 do not rotate, and the outer resistance wing 611 is evenly arranged on the upper inner side of the outer carrier ring 61; an inner resistance wing 621 is provided on the outer surface of the inner carrier plate 62, and the adjustment head 9 can be pushed when passing through the inner resistance wing 621, and the inner resistance wing 621 is located at the junction of area b and area c.

[0069] In this embodiment, refer to Figure 7 and Figure 10, the first external resistance fin 611 on the external load ring 61 is located at the junction of area a and area b. As the carbon brush assembly 400 rotates, the external fin 921 on the adjusting head 9 reaching the first external resistance fin 611 can be slightly pushed first, causing it to rotate a small angle, making the carbon brush 4 rotate a certain angle. When reaching the second external resistance fin 611, since the previous carbon brush 4 has tilted downward, the carbon brush 4 reaching the second external resistance fin 611 can be pushed a larger angle. As it passes through the remaining multiple external resistance fins 611, the carbon brush 4 rotates a larger angle until it reaches the junction of area b and area c. At this time, the rotation angle of the carbon brush 4 reaches the maximum. When the adjusting head 9 passes through area c and reaches the position of the internal resistance fin 621, the internal fin 911 is pushed to rotate in the reverse direction, restoring the angles of the carrier strip 7 and the carbon brush 4 to the dense state in area a.

[0070] It should be noted that the reason why multiple external resistance fins 611 can gradually push the external fin 921 and the pushing angle gradually increases is that the radial overlapping length between the external resistance fin 611 and the external fin 921 increases in a gradient along the rotation direction of the end seat 3. Planarizing the contact plane between each external resistance fin 611 and the external fin 921, referring to Figure 11 can better illustrate that the leftmost external resistance fin 611 is the first one (the external resistance fin 611 at the junction of area a and area b), and they are arranged horizontally in sequence. The rightmost external resistance fin 611 is the last one (the external resistance fin 611 at the junction of area b and area c). Then, when the external fin 921 passes through the external resistance fin 611, the contact area between the two increases one by one. Therefore, the external resistance fin 611 can gradually increase the angle of pushing the external fin 921, making the angle of the carbon brush 4 gradually increase.

[0071] Preferably, the position of the negative pressure pipe 300 is opposite to the area where the internal resistance fin 621 and the external resistance fin 611 meet.

[0072] Combined with Figure 12 and Figure 13 shown, in order to ensure the synchronous rotation of the end shaft 72 and the adjusting head 9, a limiting ridge 721 is provided axially on the outer peripheral surface of the end shaft 72, and a groove adapted to the limiting ridge 721 is provided on the inner wall of the adjusting head 9, so that the adjusting head 9 can slide on the end shaft 72 without affecting co-rotation.

[0073] The reason for setting the adjusting head 9 to be able to slide on the end shaft 72 is to set a locking device when the end shaft 72 is in area a. This locked state can limit the self-rotation of the adjusting head 9 in area a, thereby preventing the end shaft 72 and the carbon brush 4 from deflecting in area a and ensuring that the carbon brush 4 can brush the cashmere paper normally in area a.

[0074] Combined with Figures 13 - 17As shown in the figure, specifically, the above-mentioned locking device includes the following: One side of the adjusting head 9 close to the end seat 3 is provided with a limiting post 93, and a limiting groove 32 adapted to the limiting post 93 is opened on the end seat 3. A spring 94 is installed on the side of the limiting post 93 close to the end seat 3. When the limiting post 93 is pressed into the inside of the limiting groove 32, under the limiting action of the limiting groove 32, the entire adjusting head 9 is in a state where it cannot rotate, thus ensuring that the brushing angle of the carbon hair 4 on the cashmere paper remains normal.

[0075] Specifically, in order to achieve the purpose of the limiting post 93 entering the limiting groove 32 in area a, on the side of the adjusting head 9 away from the end seat 3, there is a force-receiving cover 8. The carbon brush assembly 400 further includes a pressing ring 5. One side lower part of the pressing ring 5 close to the force-receiving cover 8 is set as a pressure part 51, and the upper part is set as a non-pressure part 52. The axial thickness of the pressure part 51 is greater than the axial thickness of the non-pressure part 52. So when the end seat 3 rotates to drive the adjusting head 9 past the pressure part 51, the pressure part 51 can push the force-receiving cover 8, and thus the force-receiving cover 8 can push the entire adjusting head 9 to move, and the spring 94 is in a compressed state. At this time, the limiting post 93 enters the limiting groove 32, and thus the entire adjusting head 9 can limit the rotation of the end shaft 72; when the adjusting head 9 rotates to area b, the pressure part 51 no longer applies pressure to the force-receiving cover 8. Thus, due to the rebounding action of the spring 94, the limiting post 93 can disengage from the limiting groove 32. At this time, the adjusting head 9 is in a state where it can change the angle, enabling it to cooperate with the internal resistance fin 621 and the external resistance fin 611 subsequently.

[0076] Preferably, a roller 81 is arranged in the area where the force-receiving cover 8 and the pressing ring 5 face each other to reduce the friction between the force-receiving cover 8 and the pressing ring 5.

[0077] Preferably, the above-mentioned carbon brush assembly 400 further includes a fixing seat 2, and the pressing ring 5, the first disc 91, and the second disc 92 are all installed on the fixing seat 2, making the pressing ring 5, the first disc 91, and the second disc 92 in a stationary state relative to the end seat 3.

[0078] In addition, a partition 1 is provided on the outer peripheral surface of the end seat 3, and the partition 1 is used to prevent the wool debris generated when brushing the hair from entering the outer surface of the adjusting head 9.

[0079] During operation, the pulp containing cashmere fibers is sent into the papermaking equipment by a headbox for papermaking and then dried to obtain cashmere paper. The cashmere paper is sent into the carbon brush equipment. The cashmere paper enters the carbon brush equipment through the loading roller 100 and is sent below the carbon brush assembly 400 through the guiding roller 200. The motor drives the end seat 3 to rotate by driving the main shaft 10, and then the carbon hair 4 can brush the cashmere paper. During the brushing process, the spreading roller 600 located below can apply a tensile force to the cashmere paper horizontally to ensure the brushing effect.

[0080] When the carbon brush assembly 400 is working, the carbon hairs 4 in area a are in a state of brushing against the cashmere paper bristles. At this time, the force-bearing cover 8 is squeezed by the pressure part 51, and then the limit post 93 and the limit groove 32 are in a state of restricting the rotation of the adjustment head 9, that is, the carrier strip 7 is in a state where it cannot rotate by itself at this time, so as to ensure that the brushing angle of the carbon hairs 4 is accurate and stable. As the carbon brush assembly 400 rotates, the force-bearing cover 8 entering area b disengages from the pressure part 51, so that the spring 94 is released, pushing the limit post 93 out of the limit groove 32. At this time, the end shaft 72 has rotational freedom. When the adjustment head 9 reaches the first external resistance wing 611, the external wing 921 on the adjustment head 9 can be slightly pushed first, causing it to rotate a small angle, making the carbon hairs 4 rotate a certain angle. When it reaches the second external resistance wing 611, since the previous carbon hairs 4 have tilted downward, the carbon hairs 4 reaching the second external resistance wing 611 can be pushed a larger angle. As it passes through the remaining multiple external resistance wings 611, the carbon hairs 4 rotate a larger angle until it reaches the junction of area b and area c. At this time, the rotation angle of the carbon hairs 4 reaches the maximum. When the adjustment head 9 passes through area c and reaches the position of the internal resistance wing 621, the internal wing 911 is pushed to rotate in the reverse direction by the internal resistance wing 621, making the angles of the carrier strip 7 and the carbon hairs 4 return to the dense state in area a again. Then, in area c, a divergence angle is substantially formed, and the negative pressure tube 300 can absorb the fluff from area c.
