Description

TECHNICAL FIELD

[0001] The present application relates to the field of fiber processing and carding technology, in particular to a worsted cashmere and copper ammonia blended fiber processing technology and carding equipment. BACKGROUND

[0002] Worsted cashmere and copper ammonia blended fiber is a fabric woven from high-quality cashmere fibers and specially treated copper ammonia additives or another high-performance fiber through precise spinning technology. This fiber combines the softness, warmth, and luster of cashmere, while possibly having additional properties from other fibers or additives, such as wrinkle resistance, wear resistance, or flame resistance. During its production process, process parameters need to be strictly controlled to ensure that the quality and performance of the fiber are at their best.

[0003] During the fiber raising and spinning process, the dense steel needles used in the carding of the fabric surface can easily cause the fibers to raise, resulting in uneven raising. This requires trimming and carding of the pile on the surface of the fabric after raising to ensure uniform pile length. The existing trimming device uses a straight-line drum to individually card one side of the fiber layer, which cannot simultaneously trim and card both sides of the raised fabric, leading to excessively long pile that can easily harbor dirt and dust inside the fiber layer, making cleaning difficult and resulting in low work efficiency. Therefore, we propose a worsted cashmere and copper ammonia blended fiber processing technology and carding equipment. SUMMARY

[0033] Please refer to Figures 1-7 The present application provides a technical solution: a processing technology of worsted cashmere and viscose fiber, comprising the following steps:

[0037] Proportional mixing control: gold ratio of cashmere 70% / viscose 30% is adopted, considering the hand feeling of cashmere and the moisture conducting characteristics of viscose; FA201B type cotton mixing machine is used, 8-bin reciprocating cotton mixing curtain is configured, cotton mixing unevenness ≤1.2%, 0.3% antistatic agent (quaternary ammonium salt) is added, and the specific resistance of the fiber is controlled to be ≤10^8 Ω·cm; worsted core process: use cotton pulling machine to pull the fiber group into strip shape, then send the mixed fiber into the equipment for carding, first pull the mixed fiber to a high point, and let the mixed fiber layer surface be carded in advance, then dry the mixed fiber surface again, and the temperature is controlled at 75℃;

[0038] Excess dispersion filament carding: pull down the fiber layer, card both sides of the fiber layer, expand the looseness of the mixed fiber, and the mixed fiber is attached to the carding equipment on both sides, to improve the uniformity of the filament;

[0039] Dynamic hair removal: high temperature dehumidification around, using electrostatic adsorption to remove the residual fluff on the surface of the mixed fiber, which can effectively improve the texture of the mixed fiber;

[0040] e. Low temperature setting: steam pressure 0.15 MPa, temperature 110℃, setting time 90 seconds, eliminating spinning stress 36; Nano finishing: dipping 0.5% graphene modified finishing agent, improving antibacterial performance (bacteriostatic rate ≥99%).

[0041] The combing device comprises a pair of stands 1, a rope releasing disc 4 is fixedly connected to the top of each stand 1, a height limiting rod 5 is fixedly connected between the two rope releasing discs 4, a gas cylinder 3 is fixedly connected to the middle of each stand 1, a rotating plate 21 is rotatably connected to the common end of the two gas cylinders 3, a plurality of combing plates 22 are fixedly connected to the rotating plate 21 at equal intervals, an installation plate 18 is fixedly connected to the side of the stand 1 near the top of the gas cylinder 3, a profile roller 17 is fixedly connected to the top of the installation plate 18, a dispersion pruning knife 19 is fixedly installed on one side of the installation plate 18, a plurality of grabbing blocks 20 are fixedly installed on one side of the dispersion pruning knife 19 at equal intervals, a connecting frame 2 is fixedly connected to the side of the stand 1 near the bottom of the gas cylinder 3, a first rubber rod 24 is fixedly connected to one end of each connecting frame 2, a second rubber rod 25 is fixedly connected to the side of the stand 1 near each first rubber rod 24, the second rubber rod 25 and the first rubber rod 24 are parallel to each other and have the same height from the ground; an extension pipe 14 is hung at the bottom of the dispersion pruning knife 19, a reciprocating wire rod 23 is rotatably connected between the two connecting frames 2, and a sliding piece 201 is slidably connected between the reciprocating wire rod 23 and the first rubber rod 24.

[0042] Firstly, cashmere and cupro fiber are mixed together for rubbing and twisting, and then the mixed fibers are pretreated after rubbing and forming. The mixed fibers are rinsed in water bath and then dried. Then the mixed fibers and the preliminarily formed mixed fibers are connected with the pull rope 6 at one end, wherein a ready-made clamp or hook is fixedly installed at one end of the pull rope 6. Then the motor 8 is turned on, and when the motor 8 rotates, the pull rope 6 is tightened, and the mixed fibers are pulled by the pull rope 6 at one end, lifted upwards, and laid on the profile roller 17. Then the fixed clamp or hook at one end of the pull rope 6 is removed from the mixed fibers, and the mixed fibers are free-falling. Then the mixed fibers move along the installation plate 18 and the dispersion trimming knife 19. The dispersion trimming knife 19 can trim the relatively long pile, so the dispersion trimming knife 19 needs to be set a little more densely. Then the back of the mixed fibers is contacted with the plurality of grabbing blocks 20, so that the grabbing blocks 20 can trim the back of the mixed fibers. The mixed fibers are first subjected to the grabbing operation. Then the cylinder 3 can be driven to extend, so that the rotating plate 21 can rotate, and the plurality of combing plates 22 can cut into the mixed fibers, disperse the mixed fiber layer, and comb the mixed fibers in layers, which is helpful for subsequent fine and sparse drawing. When the mixed fibers at one end descend along the surface of the extension pipe 14, they pass between the first rubber rod 24 and the second rubber rod 25. A low-power dryer is installed between the first rubber rod 24 and the dispersion trimming knife 19 during installation of the equipment, which dries the surrounding air. Not only can the surface of the mixed fibers be dried, but also when the mixed fibers pass between the first rubber rod 24 and the second rubber rod 25, the first rubber rod 24 and the second rubber rod 25 can generate negative charges, which can easily adsorb the floating pile on the surface of the mixed fibers, thereby improving the smoothness of the surface of the mixed fibers and improving the quality of the finished mixed fibers.

[0043] Further, the two upright columns 1 are fixedly provided with a base on one side, the base is fixedly installed with a pair of first negative pressure pipes 27, each first negative pressure pipe 27 is fixedly connected with a partition plate 28, a plurality of partition plates 28 are sleeved with a wire grabbing roller 12, a plurality of through suction holes 1201 are formed in the wire grabbing roller 12, and a plurality of carding needles 1202 are fixedly installed outside the wire grabbing roller 12, a plurality of negative pressure holes 29 are formed in the first negative pressure pipe 27, and a passage communicated with the outside is formed in the middle of the first negative pressure pipe 27, and each first negative pressure pipe 27 is fixedly connected with an air guide pipe 13 connected with a negative pressure machine at one end; when the mixed fibers descend at one end, they will pass between the two wire grabbing rollers 12, each wire grabbing roller 12 is provided with a carding needle 1202, which is used for fine and sparse treatment of the mixed fibers, after the air guide pipe 13 is connected with the negative pressure machine, the negative pressure machine is started, the air guide pipe 13 is filled with pressure, the first negative pressure pipe 27 is filled with pressure, and the first negative pressure pipe 27 is communicated with the outside through the negative pressure hole 29. Because the wire grabbing roller 12 is provided with a plurality of partition plates 28, the inside of the wire grabbing roller 12 is relatively closed after being separated by the two partition plates 28, the negative pressure hole 29 has greater suction to suck the impurities and velvet debris in the wire grabbing roller 12, and the carding needles 1202 outside the two wire grabbing rollers 12 are in a staggered state, so that the mixed fibers can be carded on both sides, and the silk can be more uniform.

[0044] Further, a plurality of ratchet wheels 30 are installed at equal intervals outside each first negative pressure pipe 27, each ratchet wheel 30 is located between the two partition plates 28 and is fixedly connected with the first negative pressure pipe 27, a fixed cylinder 31 is fixedly installed near each ratchet wheel 30 inside the wire grabbing roller 12, a spring 33 is fixedly connected inside the fixed cylinder 31, a meshing tooth 34 is fixedly connected at one end of the spring 33, and the meshing tooth 34 and the outer circle of the ratchet wheel 30 are in contact; an air vent cover 35 is fixedly connected with a plurality of second negative pressure pipes 32, the second negative pressure pipes 32 extend into the wire grabbing roller 12, and the second negative pressure pipes 32 respectively penetrate the ratchet wheel 30 and the partition plate 28; if the impurities and velvet debris are not completely sucked in the wire grabbing roller 12, the air vent cover 35 can be connected with the negative pressure machine, so that the plurality of second negative pressure pipes 32 can generate negative pressure, expand the cleaning of the inside of the wire grabbing roller 12, and prevent the impurities from accumulating in the wire grabbing roller 12 to form blockage and cause the cleaning function to decrease.

[0045] Further, if the mixed fiber is thick, the suction force generated from the over-absorption hole 1201 may be difficult to easily penetrate the mixed fiber, so the thick mixed fiber drives the two wire grabbing rollers 12 to rotate, and the ratchet disc 30 is in a fixed and stationary state, so that the spring 33 inside the fixed cylinder 31 is always in an extension state, so that the meshing teeth 34 and the ratchet disc 30 are always in a friction gear state, and the carding needle 1202 outside the wire grabbing roller 12 presents multi-section continuous carding to the mixed fiber. Since the distance between the two wire grabbing rollers 12 is in an unchanged state, the wire grabbing roller 12 can make the carding needle 1202 pull the surface of the mixed fiber at a low speed when receiving a mixed fiber with a large thickness, thereby more quickly carding the mixed fiber into a filamentous state, reducing the drawing and carding time.

[0046] When the mixed fiber is carded, it is manually pulled to one end and placed on the drawing roller 10 and the traction roller 11 for drawing and conveying, so that the entire mixed fiber can be processed, and finally the mixed fiber is shaped at low temperature around the smoothing roller 9. After the mixed fiber is shaped, it is conveyed to the rear for next step detection and cutting work.

[0047] Further, the base is rotatably connected with the traction roller 11, one end of the traction roller 11 is sleeved with the second belt 16, the traction roller 11 and the reciprocating wire rod 23 are sleeved with the first belt 15, the first belt 15 and the second belt 16 are coaxially output driven with the end of the traction roller 11, and the base is rotatably connected with the drawing roller 10 near the traction roller 11; both sides of one end of the base are fixedly installed with the motor 8, the output shafts of the motor 8 are connected with the vertical plates 7, the drawing rope 6 is connected between the rope winding disc 4 and the vertical plate 7, and the drawing rope 6 is wound on the output shaft of the motor 8; the base is rotatably connected with the smoothing roller 9 near the motor 8, and a plurality of transition discs 26 are equidistantly fixedly installed at one end of the base. The plurality of transition discs 26 are located between the drawing roller 10 and the smoothing roller 9; the traction roller 11 can be driven by the external motor 8, and the traction roller 11 rotates to drive the first belt 15 and the second belt 16 to rotate, so that the reciprocating wire rod 23 rotates. When the reciprocating wire rod 23 rotates, the sliding sheet 201 reciprocates on the reciprocating wire rod 23, which is used for cleaning the impurities adsorbed by the first rubber rod 24 and the second rubber rod 25, and improving the cleanliness of the first rubber rod 24 and the second rubber rod 25.
