Description
Technical Field
[0001] The invention relates to the technical field of fiber processing and combing, in particular to a worsted cashmere copper-ammonia blended fiber processing technology and combing equipment. Background Art
[0002] Worsted cashmere cuprammonium blended fiber is a fabric that is woven from high-quality cashmere fiber and specially treated cuprammonium auxiliaries or another high-performance fiber through precision spinning technology. This fiber combines the softness, warmth and luster of cashmere, and may have additional properties brought by other fibers or auxiliaries, such as wrinkle resistance, abrasion resistance or flame retardancy. Its production process requires strict control of process parameters to ensure the best quality and performance of the fiber.
[0003] In the process of fiber napping and wire drawing, the dense steel needles are prone to cause fiber fluffing when combing the surface of the fabric, resulting in uneven fluffing, which requires trimming and combing the fluff on the surface of the fabric after fluffing to ensure the consistency of the fluff length. At the same time, the existing polishing device uses a straight-line roller type to comb one side of the fiber layer alone, and cannot polish and comb both sides of the napped cloth at the same time, which causes the fluff to be too long and the inside of the fiber layer to be easy to accumulate dirt and grime, which is more troublesome to clean, leading to low work efficiency. For this reason, we propose a worsted cashmere copper-ammonia blended fiber processing technology and combing equipment. Summary of the invention

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0018] See also Figure 1-7 The present invention provides a technical solution: a worsted cashmere copper-ammonia blended fiber processing technology, comprising the following steps: First, the cashmere is cleaned to remove surface dirt and impurities, and then the cashmere is pretreated: select high-quality cashmere raw materials with fiber length (≥30mm) and fineness ≤15.5μm, and require the roughness rate to be less than 0.3% and the impurity rate to be less than 0.1%.

First, pull the mixed fiber to a high point to pre-comb the surface of the mixed fiber layer, pre-comb the fiber layer, and then dry the surface of the mixed fiber again, and the temperature is controlled at 75℃; Redundant dispersed filament combing: pull the fiber layer down, comb both sides of the fiber layer, expand the looseness of the mixed fiber, and fit both sides of the mixed fiber to the combing equipment to improve the uniformity of the filament; Dynamic hair removal: high temperature dehumidifies the surrounding area, and uses static electricity to absorb the remaining fluff on the surface of the mixed fiber, which can effectively improve the texture of the mixed fiber; e. Low temperature setting: steam pressure 0.15MPa, temperature 110℃, setting time 90 seconds, eliminating spinning stress 36; Nano finishing: impregnating 0.5% graphene modified finishing agent to improve antibacterial performance (antibacterial rate ≥ 99%).
[0019] The combing device comprises a pair of columns 1, each column 1 is fixedly connected to a rope-releasing drum 4 at the top, a limited height rod 5 is fixedly connected between the two rope-releasing drums 4, a cylinder 3 is fixedly connected to the middle of each column 1, a rotating plate 21 is rotatably connected to a common end of the two cylinders 3, a plurality of combing plates 22 are equidistantly fixedly connected to the rotating plate 21, a mounting plate 18 is fixedly connected to the column 1 near the top of the cylinder 3, a profile roller 17 is fixedly connected to the top of the mounting plate 18, a dispersion trimming knife 19 is fixedly installed on one side of the mounting plate 18, and a dispersion trimming knife 19 is fixedly installed on one side of the dispersion trimming knife 19 A plurality of grab blocks 20 are fixedly installed, each column 1 is fixedly connected to a connecting frame 2 near the bottom of the cylinder 3, one end of the two connecting frames 2 is fixedly connected to a first rubber rod 24, and the column 1 is fixedly connected to a second rubber rod 25 near each first rubber rod 24, and the second rubber rod 25 and the first rubber rod 24 are at the same height from the ground and are parallel to each other; an extension tube 14 is suspended at the bottom of the dispersion pruning knife 19, a reciprocating screw rod 23 is rotatably connected between the two connecting frames 2, and a slide 201 is slidably connected between the reciprocating screw rod 23 and the first rubber rod 24.
[0020] First, the cashmere and cuprammonium fiber are mixed together and twisted. After the twisting is formed, the mixed fiber is pretreated, the mixed fiber is rinsed in a water bath, and then dried. Then, one end of the initially formed mixed fiber is connected to the draw rope 6, wherein a ready-made clamp or hook lock is fixedly installed at one end of the draw rope 6, and then the motor 8 is turned on. When the motor 8 rotates, the rope drum 4 can be rotated. After the rope drum 4 rotates, the draw rope 6 is tightened, and one end of the mixed fiber is pulled by the draw rope 6 and lifted to a higher place, so that the mixed fiber is laid on the molding roller 17. Then, the clamp or hook lock fixed at one end of the draw rope 6 is removed from the mixed fiber, and one end of the mixed fiber falls freely. Then, the mixed fiber moves between the mounting plate 18 and the dispersing trimming knife 19. The dispersing trimming knife 19 can trim relatively long fluff, so the dispersing trimming knife 19 needs to be set more densely. Then, the back of the mixed fiber is contacted with multiple grab blocks 20 to make the grab blocks 20 Block 20 can trim the back of the mixed fiber, first perform a fleece operation on the mixed fiber, and then drive the cylinder 3 to extend so that the rotating plate 21 can rotate, allowing multiple combing plates 22 to cut into the mixed fiber, disperse the mixed fiber layer, and comb and layer the mixed fiber, which is helpful for subsequent fine drawing. Then, when one end of the mixed fiber descends along the surface of the extension tube 14, it passes between the two first rubber rods 24 and the second rubber rod 25. When the equipment is installed, a low-power dryer is installed between the first rubber rod 24 and the dispersing and trimming knife 19 to dry the surrounding air. Not only can the surface of the mixed fiber be dried, but also when the mixed fiber passes between the first rubber rod 24 and the second rubber rod 25, the first rubber rod 24 and the second rubber rod 25 generate negative charges, which makes it easy to absorb the floating velvet on the surface of the mixed fiber, thereby improving the smoothness of the surface of the mixed fiber and improving the quality of the finished product of the mixed fiber.
[0021] Furthermore, a base is fixedly provided on one side of the two uprights 1, and a pair of first negative pressure tubes 27 are fixedly installed on the base, and each first negative pressure tube 27 is fixedly connected to an isolation plate 28, and a plurality of isolation plates 28 are sleeved with a wire grabbing roller 12, and a plurality of suction holes 1201 are provided on the wire grabbing roller 12, and a plurality of combing needles 1202 are fixedly installed on the outside of the wire grabbing roller 12, and a plurality of negative pressure holes 29 are provided on the first negative pressure tube 27 and communicate with the middle thereof to form a passage for circulation with the outside, and one end of each first negative pressure tube 27 is fixedly connected to an air guide tube 13 connected to a negative pressure machine; when one end of the mixed fiber descends, it will pass between the two wire grabbing rollers 12, and each wire grabbing roller 12 is provided with a combing needle 1202 for finely sparsely treating the mixed fiber, When the mixed fiber passes through the two wire grabbing rollers 12, after the air duct 13 and the negative pressure machine are connected and the negative pressure machine is turned on, the inside of the air duct 13 is filled with pressure, so that the inside of the first negative pressure tube 27 is filled with pressure. After the first negative pressure tube 27 is filled with pressure, the first negative pressure tube 27 is connected to the outside through the negative pressure hole 29. Since a plurality of isolation plates 28 are provided inside the wire grabbing roller 12, the inside of the wire grabbing roller 12 is isolated by two isolation plates 28 and each section is relatively closed. The negative pressure hole 29 has a greater suction force to absorb impurities and velvet debris inside the wire grabbing roller 12, and the combing needles 1202 outside the two wire grabbing rollers 12 are in a staggered state, so the front and back sides of the mixed fiber can be combed, and the silk formation can be more uniform.
[0022] Furthermore, a plurality of ratchet discs 30 are equidistantly installed on the outer ring of each first negative pressure tube 27, each ratchet disc 30 is located between two isolation plates 28 and is fixedly connected to the first negative pressure tube 27, and a fixed cylinder 31 is fixedly installed on the inner ring of the wire grabbing roller 12 near each ratchet disc 30, and a spring 33 is fixedly connected to the inner ring of the fixed cylinder 31, and one end of the spring 33 is fixedly connected to a meshing tooth 34, and the meshing tooth 34 and the outer ring of the ratchet disc 30 are in contact with each other; a ventilation cover is fixedly connected to one end of the wire grabbing roller 12 35. A plurality of second negative pressure tubes 32 are fixedly connected to the ventilation cover 35. The second negative pressure tubes 32 extend into the interior of the wire grabbing roller 12, and the second negative pressure tubes 32 respectively penetrate the ratchet disk 30 and the isolation plate 28. If the impurities and velvet debris are not completely absorbed inside the wire grabbing roller 12, the ventilation cover 35 can be connected to a negative pressure machine so that the plurality of second negative pressure tubes 32 can generate negative pressure, thereby expanding the cleaning of the interior of the wire grabbing roller 12 and preventing impurities from accumulating inside the wire grabbing roller 12 to form a blockage and reduce the cleaning function.
[0023] Furthermore, if the thickness of the mixed fiber is relatively large, the suction force generated by the suction hole 1201 may not be able to penetrate the mixed fiber easily. Therefore, the thick mixed fiber will drive the two wire grabbing rollers 12 to rotate, and the ratchet disk 30 is in a fixed static state, so that the spring 33 inside the fixed cylinder 31 is always in an extended and retracted state, so that the meshing teeth 34 and the ratchet disk 30 are always in a friction and toothing state, so that the combing needles 1202 outside the wire grabbing roller 12 can perform multiple sections of continuous combing on the mixed fiber. Since the distance between the two wire grabbing rollers 12 is in a constant state, the wire grabbing roller 12 can receive the thick mixed fiber, so that the combing needles 1202 pull the surface of the mixed fiber when rotating at a low speed, thereby combing the mixed fiber at a faster speed to make it appear in a filamentary state, thereby reducing the wire drawing and combing time.
[0024] After the mixed fiber is combed, one end of the mixed fiber is manually pulled and placed on the pulling roller 10 and the pulling roller 11 for pulling and conveying, so that the mixed fiber can be processed as a whole. Finally, the mixed fiber is low-temperature shaped around the smoothing roller 9. After the mixed fiber is shaped, it is conveyed to the rear for the next step of inspection and cutting.
[0025] Furthermore, a traction roller 11 is rotatably connected to the middle of the base, a second belt 16 is sleeved on one end of the traction roller 11, a first belt 15 is sleeved between the traction roller 11 and the reciprocating screw rod 23, the first belt 15 and the second belt 16 are coaxially outputted with the ends of the traction roller 11, and a pulling roller 10 is rotatably connected to the base near the traction roller 11; a motor 8 is fixedly installed on both sides of one end of the base, and the output shaft of the motor 8 is connected to a vertical plate 7, a pull rope 6 is connected between the rope drum 4 and the vertical plate 7, and the pull rope 6 is wound around the output shaft of the motor 8; the base is rotatably connected near the motor 8 There is a smoothing roller 9, and a plurality of transition plates 26 are equidistantly fixedly installed at one end of the base, and the plurality of transition plates 26 are all located between the pulling roller 10 and the smoothing roller 9; the traction roller 11 can be driven by an external motor 8, and when the traction roller 11 rotates, it also drives the first belt 15 and the second belt 16 to rotate, so that the reciprocating screw rod 23 rotates. When the reciprocating screw rod 23 rotates, the slide 201 reciprocates on the reciprocating screw rod 23, so as to clean the impurities adsorbed by the first rubber rod 24 and the second rubber rod 25, and improve the cleanliness of the first rubber rod 24 and the second rubber rod 25.
