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 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 includes the following steps: 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; 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; 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.

[0006] Further, in Step 3, a blower is used to blow air on the cashmere paper twice, and the directions of the two air blows are opposite.

[0007] 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 dust from the open carbon hairs.

[0008] Further, the carbon brush assembly further includes a headstock that can rotate actively. A carrier strip for carrying carbon hairs is provided in the area near the outer edge of the headstock. The carrier strip is rotatably installed on the headstock through a carrier shaft, so that the angles of the respective carrier strips relative to the circumferential surface of the headstock can change.

[0009] 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: The first disk has inner fins on one side close to the center of the end seat; The second disk has outer fins on one side away from the center of the end seat. The first disk is fixedly connected to the second disk; The carbon brush assembly further includes an outer carrier ring and an inner carrier plate located on the side of the end seat away from the carrier strip. Outer resistance fins are uniformly arranged on the upper part of the inner side of the outer carrier ring, and the radially overlapping length of the outer resistance fins and the outer fins increases in a gradient along the rotation direction of the end seat; an inner resistance fin is provided on the outer surface of the inner carrier plate, and the adjustment head can be pushed when passing through the inner resistance fin.

[0010] 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.

[0011] Further, a limiting ridge is provided 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.

[0012] 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 the side of the limiting post close to the end seat; The side of the adjustment head away from the end seat has a force-receiving cover; The carbon brush assembly further includes a pressing ring. The lower part of one side of the pressing 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.

[0013] Further, the carbon brush assembly further includes a fixing seat, and the pressing ring, the first disk and the second disk are all installed on the fixing seat, so that the pressing ring, the first disk and the second disk are in a static state relative to the end seat.

[0014] Further, a partition is provided on the outer peripheral surface of the end seat, and the partition is used to block the wool debris generated when blocking the brush hairs from entering the outer surface of the adjustment head.

[0015] The present invention has the following beneficial effects: (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 guaranteed, and the tactile comfort can be improved.

[0016] (2). The carbon hairs can be opened at a certain angle, so that the negative pressure pipe can be aligned with the opening angle for dust suction, thereby effectively removing the wool debris hidden in the dense carbon hairs, and thus avoiding the situation of strong static electricity caused by the accumulation of wool debris in the carbon hairs.

[0017] (3). In the production method of this cashmere paper, when the cashmere paper passes under the carbon wool from left to right, the carbon brush assembly should rotate clockwise. In area a below it, the carbon wool is in a dense state. 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 wool 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 area b deflects, making the carbon wool in area b denser, thus reserving space for the carbon wool to open in area c. There is a certain included angle between the two groups of carbon wool in area c. Then, a negative pressure tube is used to suck dust in this area, so that the lint hidden inside the carbon wool can be cleaned, ensuring the continuous operation of the carbon wool and reducing the danger brought by static electricity.

[0018] (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 area a, thus avoiding the deflection of the end shaft and carbon wool in area a, ensuring the correct angle of the carbon wool brushing the cashmere paper in area a, and improving the stability during brushing.

[0019] 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 mode

[0022] 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.

[0023] In the description of the present invention, it should be understood that the terms "opening", "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 referred components or elements must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0024] Next, according to Figures 1 - 17 Describe a production method of cashmere paper provided by an embodiment of the present invention.

[0025] Please refer to Figure 1 , an embodiment of the present invention provides a production method of cashmere paper, including the following steps: A production method of cashmere paper, including the following steps: Step 1: Mix plant fibers and animal fibers to make a raw material slurry, send the slurry into a papermaking device using a headbox for papermaking, and dry it to obtain cashmere paper; 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, simulating cashmere fluff; 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.

[0026] 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, simulating cashmere fluff, and due to the blowing effect, the fluffiness of the fibers can be ensured, improving the tactile comfort.

[0027] 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%.

[0028] Preferably, in Step 3, use a blower to blow air on the cashmere paper twice, and the directions of the two blows are opposite. No matter from which direction perpendicular to the cashmere paper, as long as the directions of the two blows are opposite.

[0029] Preferably, during the brushing process in Step 2, the part of the carbon hairs 4 of the carbon brush assembly 400 in contact with the cashmere paper is in a dense state, and the carbon hairs 4 can form an open state after leaving the cashmere paper, and a negative pressure pipe 300 is used to suck dust from the open carbon hairs 4.

[0030] Therefore, the production method of cashmere paper provided by the embodiment of the present invention can effectively remove the lint hidden in the dense carbon hairs 4, thus avoiding the situation of strong static electricity caused by the accumulation of lint in the carbon hairs 4.

[0031] Combined Figure 2 , the above-mentioned carbon brush device is as Figure 1 shown, and its main components are a feeding roller 100, a guiding roller 200, a carbon brush assembly 400 and a carding plate arranged in sequence. The cashmere paper dried in Step 1 is sent into the guiding roller 200 through the feeding roller 100. The cashmere paper guided by the guiding roller 200 reaches below the carbon brush assembly 400. As the carbon brush assembly 400 rotates, its carbon hairs 4 can brush the cashmere paper, making the fibers on the surface of the cashmere paper stand up, simulating cashmere fluff.

[0032] 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 horizontally 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.

[0033] Combined Figures 3 - 5 As shown, in order to achieve the purpose that the carbon hairs 4 can form two states of being open or dense, the specific operation is as follows. The carbon brush assembly 400 includes two end seats 3 arranged side by side. A carrier strip 7 for carrying the carbon hairs 4 is provided in the area near the outer edge of the end seat 3. A plurality of carrier strips 7 form an axially hollow cylindrical structure, and the two end seats 3 are formed into an integral structure. Here, the carrier strip 7 is rotatably mounted on the end seat 3 through a carrier shaft 71, so that each carrier strip 7 has a certain degree of rotational freedom, and then the angle of the carbon hairs 4 on the carrier strip 7 relative to the circumferential surface of the end seat 3 can change.

[0034] It should be noted that, in fact, the density of the carbon hairs 4 is not Figure 3 and Figure 4 the state of one circle after another presented in Figure 3 and Figure 4 Part of the carbon hairs 4 are implanted in the carrier strip 7, which can make the picture clearer. In fact, the carbon hairs 4 are covered on each carrier strip 7, as shown in Figure 6 the state shown.

[0035] Referring to Figure 7 shown, it should be noted that when the cashmere paper passes from left to right below the carbon hairs 4, the carbon brush assembly 400 should rotate clockwise. The area a below it is the dense state of the carbon hairs 4. The extension line of the carrier strip 7 in this area should be located on the diameter of the end seat 3. The carbon hairs 4 in this area also have the same angle and orientation as the bristles in the prior art; as the carbon brush assembly 400 rotates clockwise, the carrier strip 7 in the b area deflects. The specific deflection direction is as shown in Figure 7 shown as deflecting downward, making the carbon hairs 4 in the b area denser, so as to reserve space for the carbon hairs 4 to open in the c area. There is a certain included angle between the two groups of carbon hairs 4 in the c area, so that the negative pressure tube 300 is used to suck dust in this area, so that the lint hidden inside the carbon hairs 4 can be cleaned.

[0036] Specifically, the negative pressure tube 300 is located outside the circular structure formed by the carbon hairs 4. Refer to Figure 2 .

[0037] Preferably, a connection head 31 is provided at the center of the side of the two end seats 3 facing away from each other. A main shaft 10 is assembled on the connection head 31. One of the main shafts 10 should be driven by a motor to drive the connection head 31 to rotate, and then the rotation of the end seat 3 is realized, forming the rotation state of the entire carbon brush assembly 400.

[0038] 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.

[0039] 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.

[0040] In this embodiment, refer to Figure 7 and Figure 10 , the first outer resistance wing 611 on the outer carrier ring 61 is located at the junction of zone a and zone b. As the carbon brush assembly 400 rotates, the outer wing 921 on the adjustment head 9 that reaches the first outer resistance wing 611 can be first slightly pushed to rotate it at a smaller angle, so that the carbon bristles 4 rotate a certain angle. When it reaches the second outer resistance wing 611, since the previous carbon bristles 4 have been tilted downward, the carbon bristles 4 that reach the second outer resistance wing 611 can be pushed at a larger angle. As it passes through the remaining multiple outer resistance wings 611, the angle of rotation of the carbon bristles 4 is larger until it reaches the junction of zone b and zone c. At this time, the rotation angle of the carbon bristles 4 reaches the maximum. When the adjustment head 9 passes through zone c and reaches the position of the inner resistance wing 621, the inner wing 911 is pushed to rotate in the opposite direction, so that the angle of the carrier strip 7 and the carbon bristles 4 is restored to the dense state of zone a.

[0041] 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 fins 611 and the external fin 921 increases in a gradient along the rotation direction of the end seat 3, making the contact planes of each external resistance fin 611 and the external fin 921 planar. Refer to Figure 11 which 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). When the external fin 921 passes through the external resistance fins 611, the contact area between the two increases one by one. Therefore, the external resistance fins 611 can gradually increase the angle of pushing the external fin 921, and the angle of the carbon wool 4 gradually increases.

[0042] 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.

[0043] Combined with Figure 12 and Figure 13 As shown, in order to ensure the synchronous rotation of the end shaft 72 and the adjustment head 9, a limiting ridge 721 is provided along the axial direction 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 adjustment head 9, so that the adjustment head 9 can slide on the end shaft 72 without affecting the co-rotation.

[0044] The reason for setting the adjustment 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 adjustment head 9 in area a, thereby preventing the end shaft 72 and the carbon wool 4 from deflecting in area a and ensuring that the carbon wool 4 can brush the cashmere paper normally in area a.

[0045] Combined with Figures 13 - 17 As shown, specifically, the above-mentioned locking device includes the following: The side of the adjustment head 9 close to the end seat 3 is set as a limiting column 93, a limiting groove 32 adapted to the limiting column 93 is opened on the end seat 3, and a spring 94 is installed on the side of the limiting column 93 close to the end seat 3. When the limiting column 93 is pressed into the internal part of the limiting groove 32, under the limiting action of the limiting groove 32, the entire adjustment head 9 is in a state where it cannot rotate, thus ensuring that the brushing angle of the carbon wool 4 against the cashmere paper maintains a normal state.

[0046] Specifically, in order to achieve the purpose of the limiting column 93 entering the limiting groove 32 in the a zone, a force-bearing cover 8 is provided on the side of the adjustment head 9 away from the end seat 3, and the carbon brush assembly 400 also includes a pressure ring 5, the lower part of the side of the pressure ring 5 close to the force-bearing cover 8 is set as a pressure part 51, and the upper part is set as a non-pressure part 52, and 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 adjustment head 9 to pass through the pressure part 51, the pressure part 51 can push the force-bearing cover 8, so that the force-bearing cover 8 It can push the entire adjusting head 9 to move, and the spring 94 is in a compressed state. At this time, the limiting column 93 enters the limiting groove 32, so that the entire adjusting head 9 can limit the rotation of the end shaft 72; and when the adjusting head 9 rotates to the b zone, the pressure part 51 no longer applies pressure to the force-bearing cover 8, so that due to the rebound effect of the spring 94, the limiting column 93 can be separated from the limiting groove 32. At this time, the adjusting head 9 is in a state where it can change its angle, so that it can subsequently cooperate with the inner resistance wing 621 and the outer resistance wing 611.

[0047] Preferably, a roller 81 is provided in the area where the force-bearing cover 8 and the pressure ring 5 are opposite to each other, so as to reduce the friction between the force-bearing cover 8 and the pressure ring 5 .

[0048] Preferably, the carbon brush assembly 400 mentioned above also includes a fixing seat 2, and the pressure ring 5, the first plate 91 and the second plate 92 are all installed on the fixing seat 2, so that the pressure ring 5, the first plate 91 and the second plate 92 are stationary relative to the end seat 3.

[0049] In addition, a partition plate 1 is provided on the outer peripheral surface of the end seat 3 , and the partition plate 1 is used to prevent hair scraps generated when brushing the bristles from entering the outer surface of the adjustment head 9 .

[0050] During operation, the pulp containing cashmere fibers is fed into the papermaking equipment using a headbox pulp for papermaking and dried to obtain cashmere paper, which is then fed into the carbon brush equipment. The cashmere paper enters the carbon brush equipment through the feeding roller 100 and is fed to the bottom of the carbon brush assembly 400 through the guide roller 200. The motor drives the end seat 3 to rotate by driving the main shaft 10, so that the carbon hair 4 can brush the cashmere paper. During the brushing process, the spreading roller 600 located below can apply tension to the cashmere paper in the horizontal direction to ensure the brushing effect.

[0051] 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 portion 51. Subsequently, 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 portion 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 a degree of rotational freedom. Thus, when the adjustment head 9 reaches the first external resistance fin 611, the external fin 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 fin 611, since the previous carbon hairs 4 have tilted downward, the carbon hairs 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 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 fin 621, the internal fin 911 is pushed to rotate in the reverse direction by the internal resistance fin 621, making the angles of the carrier strip 7 and the carbon hairs 4 return to the dense state in area a. Subsequently, a divergence angle is substantially formed in area c, and the negative pressure tube 300 can absorb the lint from area c.
