Description

 Roller air suspension carding method and special animal fluff combined carding machine

Technical field

 The invention relates to a carding method and equipment for special animal fluff in the textile industry, in particular to a roller airflow suspension carding method and a special animal fluff combined carding machine.

Background technique

 At present, the carding process in the textile industry, especially the traditional roller carding equipment used in cashmere, yak, camel, and other special animal fluff carding processes, can be divided into "three roller Randolph transfer, centrifugal carding principle equipment", "Equipment for three-roller rotor turning, centrifugal carding principle" and "Equipment for centrifugal carding fan exhausting principle of licker-in roller".

 The first tillering device: After the thick combing rollers get the tufts from the front input roller, they are separated by centrifugal force. Then the split tufts are gathered on the card clothing of the roller by the doffer condensation roller, and then transferred to Head to the roller, and enter the next process, two kinds of carding equipment: the thick carding rollers get the tufts from the front input roller and use centrifugal force to separate them, and then the disturbed tufts are gathered by the wind wheel transfer roller On the clothing on the surface of the roller, it is turned to the backward roller and sent to the next process. The carding principle is to use the centrifugal force generated by the dividing roller at a certain process rotation speed, so that when the tuft is in the downward position, the material held on the card clothing of the dividing roller has a separation effect, and its quality is large. Coarse cavity hair, fine bristles, large impurities, and other types of coarse hair with good straightness, weeds, etc., which are not easy to be held by the clothing, are separated from the clothing by centrifugal force and are shredded, and the quality is small , A certain degree of curly hair and other materials are not easy to be separated and continue to be held by the card clothing attached to the card clothing to be transferred. The former is the use of the role of the doffer condensation roller and the coarse comb roller roller The relay is used for the transfer of hairs using the staggered action of the needles between the wind wheel transfer roller and the thick carding roller. The centrifugal carding fan of the licker-in roller is used for carding. The device uses centrifugal carding with the strong impact of licker-in rollers, and then the hairs on the surface of the card clothing are transferred by the fan under negative pressure. This carding device also has the function of strong carding force and repeated multiple channels of machinery. Hit points Comb, the cutting rate is high, and the fiber loss is large. Not only the villi are cut and broken, but also the bisexual hair and fine bristles are also cut and broken. This makes it difficult to separate the thick hairs. A considerable part of the bisexual hair that cannot be separated is mixed with fine bristles to become fine plush and cannot be extracted, which has become a problem of substandard products (short pile, second-class products) and underfoot (fine plush).

 The fluff carding machine of Japan is a typical device of the principle of centrifugal wart fan exhausting and turning. The carding machine is a carding machine with a strong carding mechanism that prepares lint rollers and fan transfer for cashmere. The fiber loss rate is 15%, the finished product contains a crude content of 0.2%, and the impurity content is D.〗% (Provided by the instruction manual);

 The carding machine in the United Kingdom is a carding equipment with a roller carding roller with double feed rollers, licker-in rollers and rotors as its main body. The promotion rate is 93%, and the fiber loss rate (and first-rate rate) is not Considering that the finished product contains a crude content of 0.4% and an impurity content of 0. 〖%;

Replacement page (Article 26) The LFN 1 cashmere combined carding machine in our country is a roller planter with a roller carding roller transferred by a thick roller, and is equipped with a licker-in roller and a cover carding device. Its extraction rate is 85%. The fiber donation rate is 1 Γ /. 2%, the finished product contains a crude rate of I). 2%, the impurity rate is 0.2%;

 Practice has proved that although the above carding machine 上述 cleans the coarse cavity hairs that have a large difference in quality from cashmere in the raw cashmere, the fine hairs with good straightness and large impurities have a better effect, but they contain The fine bristle with a small difference in quality from cashmere, the coarse and fine hairs with a certain degree of curl have a poor separation effect, and the machine is easy to be entangled, the clothing is easy to wear, easy to sink, and the reliability of the equipment process is poor. Defects, great damage to the hair, the overall carding efficiency is also low, and there are certain defects in the velvet method.

 The following further describes the roller airflow carding method and the special animal fluff combined carding machine disclosed by the invention with reference to the accompanying drawings and embodiments.

 Figure 1 shows the process flow of the roller air suspension carding method of the present invention. The tufts are fed by the feeding rollers and are divided by the rollers (the number of the rollers is determined by the process requirements, generally 3 or 5). Root) After holding. First, the centrifugal force generated by the rotation of the carding roller is used for centrifugal carding and card clothing to comb and comb the hair tufts, and the texture of the hair tufts is large, and it is not easy to be held by the card clothing. Coarse hairs, type 2 hairs, fine bristles, thick hairs, large impurities and straightness. Other types of thick hairs are separated into suspensions. Of course, the isolates also include loose single fibers that cannot be held. Fluff, the tufts on the combing roller are then "combed" by the airflow impact force formed between the two adjacent rollers, so that the tufts are loosened and the Miscellaneous, fine bristles, type 2 hairs, coarse and fine hairs with a small degree of curvature, and single fibrous fluff are once again carded out, and fall from the roller to become a suspension isolate. The hair clusters remaining after carding on the tilling roller It will be output by the velvet machine such as the doffer roller or the velvet knife. Due to the rotation of the dry carding roller, a certain mechanical design creates a roller airflow layer in the same direction as the hair clusters (rightward as shown in Figure 7) through a certain mechanical design. This airflow layer will face the self carding roller. The separated carded material is subjected to suspension tillering (secondary carding in which the fluff with a small weight is suspended by the airflow layer and moves to the right with the air layer, and finally collected by the suspended fluff retractor 抅 such as a backward roller or a large exhaust roller. It is mixed and output with the tuft transferred from the licker-in roller, and the thicker coarse cavity hair, large impurities and other coarse hairs, type 2 hair, fine bristles, thick hairs, dander, etc. become air flow separators. Falling to the lower part of the device becomes a falling object, and the airflow of the airflow layer finally enters the hollow exhaust roll (also known as the air vent dust cage) to separate the dust and other dust and lead the air outside the machine.

 Fig. 2 'shows a first embodiment of the method, which is a roller air suspension suspension carding method using a combination of doffer rotor and airflow rotor ^, which can be used in the main process of cashmere carding. The combing section, the process flow is that the tuft is held and rotated by the planting rollers (which can be arranged in sequence or five), and the card is anxious and the centrifugal force is used to make the rough hair ≤hair, large impurities, and single fibrous fluff. After being separated, the carding process is performed again by the impact of the air flow between the two rollers. The tufts on the final carding roller are transferred by the doffer roller of the fluffing mechanism, and then transferred to the lower roller. The separating roller of a process, and the suspended separator is suspended and combed by the air current layer produced by the separating roller. The coarse hairs and large impurities fall into falling objects, and the fluffs move to the right with the airflow, and finally flocculate at The collector 抅 is reversed to the roller, and the airflow entrains the dust from the hole on the surface of the exhaust roller into the inside of the exhaust roller and is discharged outside the machine.

 Fig. 3 shows a second embodiment of the method, which is a roller air suspension suspension carding method using large and small venting rollers as paddle cashmere, which can be used for cashmere carding process. The process, the front part of the process flow is the same as the embodiment, except that the tufts on the final carding roller are switched from the carding by the airflow switching action of the depilation knife and guided by the airflow of the shroud. The fluff suspended in the air flow formed by the opening rollers is driven by the air blower rollers, and is driven by the air flow layer to condense on the surface of the large air blow roller which is collected by the suspended fluff, and then output by the large and small νΙΙΙ wind. The dust-containing positive-pressure airflow is discharged through the mesh of the large and small venting rollers.

 The airflow switching effect of the defluffing knife is based on the last combing roller rotating at a high speed, and the airflow is shaped on the surface of the roller. When the airflow reaches the edge of the defluffing knife, it generates an airflow that flows outside the blade. This airflow makes data. | Ffi

Replacement page (Article 26) .1; The tuft rollers are detached and led to the large and small vents along the diversion green, and the airflow is the same as II †, and this airflow will also lead to the large and small airflow in the floating airflow. The air-extracting roller makes it fluff on it, so this method will not damage i ¾ hair.

 In summary, the roller air suspension carding method provided by Mu invention is mainly based on aerodynamic principles.

: The buoyancy of the airflow surface layer generated by the surface of the 1'J Chuan Roller above the critical speed, and the airflow is suspended and separated. In this method, the floating action of the f-roller ¾ surface airflow overlying layer on the diffuse hairs entering the overlying layer makes the impurities and hairs such as f more settled and separated, thereby achieving the desired carding purpose. This method breaks through the traditional "roller centrifugal carding" theory and technology, and solves the carding failure of the traditional "roller centrifugal carding" technology and equipment (when carding below the critical speed, type 2 wool, fine steel wool, fine Coarse hair is not easy to separate and entangles the car; Bi is combed above the critical speed, and some fluff, impurities, and various coarse hairs fall into falling objects under the action of air flow and high centrifugation. Problems, such as the cashmere, yak, camel, and other special animal fluff The carding technology is improved to a new stage, and the extraction rate can be increased to more than 95%, and the fiber loss rate can be reduced to 10%.

 Fig. 4 shows a structure diagram of a double-cylinder opening loosening carding mechanism.

 Located at the forefront of the whole machine as shown in Fig. 7: Part I, including three hair-feeding rollers 2 which are arranged horizontally and sequentially behind the feeding curtain 1 and with a slight arc around the opening-closing roller 3 Roller roll 3, chest roll 5, roll roll roll 6, roll roll 7, roll 7 also includes a carding plate 4, which is placed on the top left of the chest roll 5 and roll 7 There is a carding blade, which is located on the entrance surface of the carding blade and plays a role of removing impurities.

The working surfaces of the above-mentioned various rollers and carding boards are covered with card clothing. The needle density on the card clothing is different, the front is thin and the back is dense. The middle feed roller rotates clockwise, and the other two rotate counterclockwise. Except for the chest rolls and rolls, the other rolls rotate clockwise.

 FIG. 5 shows a structure diagram of a tillering mechanism (embodiment) combining roller de-roughening, doffer agglomeration, and air flow transfer composed of a seven-roller roller. This embodiment is applicable to the preliminary scrambling process of special animal fluff combing. Located at positions II-1 and Π-2 of the whole machine shown in FIG. 7, its composition includes a three-carding roller roller, that is, a first carding roller roller 11, a carding roller 13, and a third roller. Carding rollers 15 Of course, the number of carding rollers can be very dependent on the work requirements. Female transformers, velvet rollers include a doffer roller, suspended fluff collector 抅 20, including a fluff bearing roller 21, and Including a combing triangle 27 and a ventilating small dust cage 23, except for the combing triangle Π, the other ¾ can be rotatably installed on the frame, and driven by the transmission mechanism to rotate. On the plane of the rack, three carding rollers 11, 13, and 15 are installed horizontally, carding rollers II are in front, card clothing Π, 14, and the carding triangles Π are fixed below the middle of the rollers 13, 15, respectively. The combing triangle Π has an air-flow regulating roller at the bottom right. Roller roller 15 (the last carding roller roller) is provided with a doffer roller 18 at the upper right, and a lower part of the ballast roller U is at the bottom right of the last carding roller 15 with a fluff bearing down roller 21, a roller roller The rollers 18 and t have card clothings 19 and 22 to the outside of the roller 21, and a fluff roller 23 is placed on the lower left side of the roller 21, and a vent roller 23 is provided. The vent roller 23 has a hole 2 communicating with the interior of the towel empty.

 The first carding roller roller 11 is turned counterclockwise, and the inclination direction of the needles on the card clothing Π is directed forward in the direction of rotation. The rotation of the two carding rollers i 3 is clockwise, and the needle on it The oblique direction of the needles of the cloth is facing forward in the direction of rotation, and the last rotation of the roll roller 15 is counterclockwise, and the inclination of the needles of the needles on the cloth is inclined.

8 Replacement page (Article 26) The direction key moves forward in the direction of rotation. The direction of the doffer roller 18 is clockwise, and the direction of inclination of the needle of the card clothing 19 is backward. The direction of the fluff bearing guide roller 21 is clockwise. The inclination direction of the needle of the card clothing Π is forward, and the direction of the ventilating small dust cage 23 is clockwise. The roller is a hollow simplified, and there are holes 24 on the roller wall to communicate the inside and outside of the simplified Chinese. Layers of air and dust are drawn out.

 The working principle of this embodiment is as follows-the hair tufts transferred from the upper-level carding mechanism are under the action of the three carding rollers II, 1 3, 15 and the opening and carding, due to the high centrifugal force and the effect of each roller. The role of the triangular triangular airflow zone is to comb the single-fiber mixed tufts into the airflow surface layer at the lower part of the mechanism. These tuft mixtures are based on the principle of aerodynamics and have a heavier mass and a larger inertial force. This kind of coarse hair and impurities overcome the winding resistance of the surface layer, air buoyancy and other forces move to the outside of the air surface layer until it leaves the air surface layer and falls into a falling object, while the lighter fluff is held on the surface. Inside the layer, the fluff bears the chop rollers and the air venting small dust cage. The airflow leads the dusty mixture out of the machine through the small air venting dust cage. In the process, the fluff clusters that are not opened are passed through three combs. The grip of the roller is not loosened during the process of being turned on the roller until it is condensed and transferred to the fluff by the doffer roller. The chopped rollers are transferred to the roller together with the fluff on the roller through the suspension separation area. Next carding machine Re-carding. Due to the different turning of the carding rollers 1), air vortices will form in the triangular area below the rollers U, 15 and affect the suspension separation effect. The carding triangle will destroy the air vortices formed in the triangular area. State, so that the fiber moves and suspends according to the airflow direction set by the process, and behind the slitting triangle 27, the lower left of the carding roller 15 is the rear of the carding roller, which is clockwise and the next Below the slitting roller, it is better to have a counter-rotating or smoothing (depending on the specific different raw materials). The clockwise rotation of the air-adjusting roller, the outer surface of the roller 25 is also covered with card clothing, its role is to control the opening The size of the airflow layer produced by the roller is to form a suitable suspension airflow belt, which is beneficial to the separation of different raw materials.

When this embodiment is used for carding cashmere, its technical parameters may be

 Carding roller 1 1, outer diameter 25 2 mm

 Speed 230-300 rpm

 Carding roller Π, outer diameter mm

 Revolutions per minute

 Tiller roll 1 5 with 2 mm outer diameter

 Number of revolutions 4 8 β-6 20 rpm

With the above-mentioned diameter and number of revolutions of the opening roller, a roller airflow sufficient to suspend the cashmere can be generated.

 Compared with LFN 24 1 roller roller doffer roller transfer carding machine 抅, this machine has a great change in principle and function. First of all, the form of turning is no longer that the fibers are thrown on the chop-roller in the form of fluff (this kind of fiber is not conducive to carding and easily becomes a falling object). The post gets a normal uniform fiber layer.

 In addition, the machine is transferred to a non-contact rotor, and in the rotor rotor, the needle of the dry rotor must be inserted into the roller needle of the roller, which causes the defect of easy wear of the steel and affects the stability of the operation.

 In addition, the machine's most unique design allows it to form an air suspension suspension separation belt under the carding rollers, so that it has a strong function of removing coarse particles and impurities and reducing the amount of lint in the falling objects. control ability. This principle

 III ί> shows the five parts of the flat rollers to remove the rough, air suspension separation, the wind to the wind out of the pile position 111 shown in Figure 7, its composition includes the first, two, three, four, five total 5 carding rollers, namely carding rollers 29, 31, 3), 5), and corresponding card clothing 30, Π, 34, 36, .19 outside the rollers, carding rollers. 33. The direction of rotation is counterclockwise, and the inclination direction of the needles of the clothing is forward. The carding rollers 31, 35 are turned clockwise, and the direction of inclination of the needles of the clothing is forward. A carding roller roller) There is a fluffing mechanism I fl at the upper right, which includes a depilation knife 40, and there is a certain gap between the depilation knife 40 and the carding roller Π (for example, 0.1-0.5¾ meters), A deflector 40 is connected to a deflector hood 41. A fluff collector for the fluffing process is installed behind the carding roller 37. It includes a large exhaust roller (large dust cage) 2. The large exhaust roller is a Hollow carcass with holes 43 communicating between the inside and the outside, and a small air vent roller (small dust cage) above the large air vent roller 42, which has inner and outer The through hole 45, the gap between the large and small exhaust rollers is 3 to 7 mm, the large exhaust roller rotates clockwise, the small exhaust roller rotates counterclockwise, and it is below the opening roller 31, It is better to have an air-flow control roller. The clearance between the roller and roller 31 is 0.2-fl.4 mm. Below the roller between roller 3! And roller 37, roller 35 and roller A carding triangle 48 is provided below each of the carding rollers 31.

 The working principle of this embodiment is as follows: on the first 4 carding rollers, the fibers are further carded, decomposed, and centrifuged during the transfer of the fibers from the carding rollers to the fibers. At the same time, when the carding rollers carry When the fibers reach the descending position, the tufts in the tufts that are combed into a single fibrous shape are combed between two adjacent rollers by the airflow formed between the two rollers, and are separated from the surface of the clothing and become suspended. The separator enters the roller airflow layer, and under the influence of gravity and flowing airflow layer, through the band suspension of the airflow layer, fine bristles and type 2 hairs are separated and sink, and the villi continue to move along the airflow layer. Under the action of the high-speed centrifugal force of the five carding rollers and the air flow layer formed on the outer surface of the roller, the skin clusters (fiber bundles that coexist with the skin and fibers) and impurities in the hair clusters are quickly removed from the air flow. The layer is detached from the layer and suspended and combed, and the pure fluff after combing by the airflow is flocculated on the surface of the large and small exhaust rollers driven by the airflow layer, and the fleece is transferred out by the exhaust rollers. Airflow through the large and small mesh vent air vent in addition to the roller.

 The tufts held by the combing roller roller Π are removed by the air flow switching action of the de-fluffing blade 40 and are guided into the large and small exhaust rollers along with the air flow under the shroud, together with the fluff condensed on the exhaust rollers. Out of wool.

 When the wood embodiment is used in the cashmere process of cashmere, its parameters can be

 Carding roller Π outer diameter 2ί i 2 mm, revolutions 230 -300 / min

 Carding rollers 29 outer diameter 25 ι2 mm, revolutions 430 70 / min

 Carding rollers 31 outer diameter 2! 2 mm, revolutions 550 -580 / min

 Carding rollers 33 outer diameter 2ί 12 mm, revolutions 680 -750 / min

 Carding roller 35 outer diameter 2: i2 mm, revolutions 1160-1220 / min

 Carding rollers 27 outer diameter 2l i2 mm, revolutions 230 -300 / min

 Small ventilating roller 21 outer diameter 1:! 0 mm revolutions 45-ί points

 Large exhaust roller 39 outer diameter 380 mm revolutions 1. 5-2 minutes

 With the above diameter and number of revolutions, a sufficient suspension airflow can be generated around the carding rollers.

 This part mainly uses the centrifugal de-roughening effect of the flat roller and the suspension and separation effect of the air layer to achieve buckling and removal.

Replacement page (Article 26) Peel and remove miscellaneous objects. The fibers are transferred to the two-stage carding machine by the use of the wind and condensation of the large and small dust cages. This carding mechanism has very little damage to the fibers because there is no combing effect of the needle tip on the needle tip.

 Through proper adjustment of the process parameters, the amount of fluff in the fall is not much. In the design, the combing triangle is set to break the effect of the air vortex formed on the triangular area on the separation of coarse hairs, so as to force the fibers in the moving state to move in an uncertain direction to ensure the process requirements.

 Compared with the traditional doffer chopping knife way, the mechanism has simple crust formation, slight fibrous damage, and good falling objects, and avoids the failure of the doffer turning caused by the sunk needle.

 Fig. 8 shows a schematic diagram of the knots of the double-special wide-feeding carding machine 抅 57, which is located at the position of picture 57 in the whole machine shown in Fig.7. The machine frame includes a carding plate 50 fixed on a frame and a working surface at the end of the carding plate. The upper part of the working plate is provided with a velvet roller 51, which is matched with the carding plate working surface. The working surface of the roller 54, the pile card 51 facing the licker-in roller M has two working areas, a first working area D and a second working area E. The first working area is composed of an inclined plane Π above and a bottom The second working area is composed of the second working area and the inclined plane below the plane 53. An arc is connected between the plane 53 and the plane. The arc forms a groove between the plane 53 and the plane 56. Bad 55, commonly known as the second trench, it separates the first and second work. The planes 52 and 5 are inclined in the same direction with respect to the vertical 52 plane, and the inclination angles with respect to the vertical plane are α, β, θ, respectively. There may be only one plane 52 in the first working area D, and there is a circle between the plane 52 and the plane. The arcs meet and form a groove 55. In the first working area D, the angle α of the plane 52 and the vertical plane is 10-14. , Preferably 11-1 Γ, the vertical length is 22-28 (when there is only one plane 52, the length is 32-3 ffi), the angle between the plane 53 and the vertical plane is 15-20 °, the best It is 16-17. The length in the vertical direction is 10-15nim, and the angle Θ between the plane 56 and the vertical plane is 24-26 °, preferably 5-25 °. The length in the vertical direction is U-22niffi. The length in the vertical direction should vary with the diameter of the licker-in. The values in the above embodiments are those when the diameter of the licker-in is nmi (common value).

 When working, the distance between the plane 52, 53 and the carding roller is 43%. 〃, flat and 56 with points licker-in

The spacing of 54 is 12% -10%. ". In the first working area, the needle group of the lancing roller first combs the fibers first, and smoothes the fibers. When the first working area has two planes, the effect of the puncture carding is greater than that of only one plane. The fiber group enters the second work area, and the tip of the licker-in roller further perturbs the straightened fiber group. At this time, the long fiber bundle is in the second work area under the grip of the velvet roller 51. After being combed and struck, one end of the short fiber bends into the second trench and is held by the fibrous layer, and the other end is combed by the carding roller in the second working area. The distance from the point to the second working area with a small gap is greater than twice the average length of the fed fluff. In theory, the breaking force on the long fibers is very small in the combing blow, and the The breaking force and striking force of the fiber tend to fl, so the damage rate of the fiber is greatly reduced. After testing, the damage rate can be reduced by more than 54% compared with the damage rate of the prior art combing card.

 The machine adopts a double-wide working surface. The carding process is to pierce and comb the fibers through the licker-in card clothing under the real grip of the velvet roller and the virtual grip of the second nasal groove. The combing blow effect completes the whole combing process, which has sufficient treatment, small strike force, small fiber loss, and high impurity removal efficiency.

 Fig. 9 shows the structure diagram of the automatic peeling machine 抅 28 for the cover-scraping vacuum needle-skinning skin. The position of the figure Π in the whole machine is shown in the figure.

 The cover trigger cloth is supported by the cover wheel 60 as shown in FIG. 9 and rotates and travels with the counterclockwise rotation of the cover wheel M.

Replacement page (by-law 26 糸) There is a needle 5 9 on the cover card clothing 5 S. The tilt direction is toward the rear of the walking direction. It also has a 41 "roller 6 1. The needle roller 6 1 also rotates counterclockwise. The needle roller 6 1 is driven by the support of the frame and the conveyor 旋转. The needle roller 6 1 is provided with a needle clothing 6 2. The needle is tilted toward the rear of the direction of rotation. The clothing 6 2 and clothing 58 In contrast to the needle, a funnel-shaped air hood 6 6 is provided on the outer cover of the needle roller, and the lower side wall plate of the air hood becomes the lower deflector. The gap between the end of the lower deflector 6 4 and the cover trigger cloth 5 8 should be It is adjusted according to the amount of air suction, so that the skin that falls by vibration and impact can fall without being drawn into the air hood 66 by the wind. The upper part of the air hood is provided with a retractable upper cover plate 6 7 There is a gap A between the end of the cover plate and the card clothing of the cover plate. The gap must not be too large, so as to prevent the negative pressure in the airflow cover from being too small or not forming a negative pressure. This interval also causes the negative pressure airflow to mainly form on the lower deflector. The gap il: can prevent fluff on the needle-knife roller 61 from being thrown onto the cover card clothing. The gap Λ is generally about 3 ¾ meters. The end of the upper plate is also connected with the needle of the needle-knife roller 61. Inter-fi B having between 62, acting between the gap with Λ P, typically a gap β (| - 2mm) mm.

 A drafting knife is installed at an appropriate position inside the airflow 如 If the air is drawn into the airflow hood 66, the wind is extracted from the lower opening 63 (such as the arrow (: direction) to make a negative pressure inside the airflow hood. The drafting knife 65 is a triangular loading surface The pillar or a flat plate is used to guide the fluff sucked in between the needle copy roller and the lower deflector to the outlet 6 3 without entering the gap between the roller 61 and the cover 66.

 The working principle of the vacuum flower needle and skin-skin separation mechanism of this cover is as follows:

 The miscellaneous hair attached to the cover card clothing 58 meets the card clothing 62 on the needle roller 61 when turned counterclockwise. At this time, the one end containing the miscellaneous hair is held by the cover card clothing and the other end is The high-speed rotating needle-knitting needle cloth 6 combs and blows, causing throbbing to separate the velvet from impurities and the skin. At the same time, under the action of the negative pressure air suction between the lower diversion lever and the needle-knife roller, the skin The fur and grass are separated from the bushes and then fall off the ends of the lower deflector 64 to become a falling object, while the reusable fluff is guided by the needle roller cloth 6 2 The air flow between 64 is moved into the air hood along the surface of the drainage knife 65, and is sucked away by the negative pressure in the air hood from the outlet ϋ and sent to the process feeding point through the pneumatic conveying pipe to participate in the processing of the previous process, and adjust the gap A, The size of B can prevent the fluff on the needle roller from being thrown on the cover clothing at the entrance.

 The water-covered pole vacuum vacuum needle and skin-skin separation mechanism have improved the equipment's ability to comb the skin and the hair removal rate. Because the fleece cutting knife is subtracted, the mechanism has a long life, reliable operation, and reduced Labor intensity.

There is a burr roller under the licker-in roller 0, a bleeder blade 7 1 under the burr roller 7 0, a burr 74 near the burr near the burr, and a dust cage machine in front of the burr 69. The dust distribution cage mechanism is composed of a large dust cage 42 rotating clockwise and a small dust cage rotating counterclockwise above the small dust cage. The small dust cage has a diversion tube 75 connected to a hair cutting knife.

 Under the action of the high-speed reverse air flow formed on the surface of the sanding roller, it changes from passive roughing to active roughing. The thickened fiber layer is condensed on the dust cage with the airflow along the shroud and transferred out of the machine. This kind of unit scouring removes rough hair and thin bristles. The bristles ability is second only to the velvet puller, licker-in roller, hair roller and dust cage transfer machine. However, the unique very low fiber damage rate makes this mechanism. It is very suitable for auxiliary hair removal of fine bristles, type 2 hairs and skins, to achieve the purpose of enhancing the ability of removing hair without increasing the fibrous damage. The fiber donation rate of this machine is generally below 6%, but this
