Embodiment 2

(12) Referring to FIG. 1 to FIG. 3 and FIG. 6 to FIG. 7, a water tank 23 is mounted at a top position of a rear end of the water conveying pipe 10. A water inlet 24 communicated with a bottom of the water tank 23 is formed in the top position of the rear end of the water conveying pipe 10. A rear end surface of the water conveying pipe 10 is connected with a pressure plate 26 through an elastic telescopic rod 25. A center of the pressure plate 26 is connected with a piston plate 28 through a transverse rod 27. The piston plate 28 is located in the water conveying pipe 10. A guide plate 29 is arranged at a rear end of the pressure plate 26. The guide plate 29 is connected to the other end of the double-shaft motor 20. A water inlet hole 102 is formed in the inner wall of the water conveying pipe 10 in a penetrating manner, and a water guide cavity 103 is arranged on an outer side of the water inlet hole 102. The water guide cavity 103 is formed in an inner wall of the mounting sleeve 101. The mounting plates 11 on the outer side of the mounting sleeve 101 are internally hollow and are communicated with the water guide cavity 103. Water spraying holes 104 are formed in left side surfaces of the mounting plates 11 at equal intervals and are communicated with the hollow structures inside the mounting plates 11. The water guide cavity 103 is of a cambered structure; an arc length of the water guide cavity 103 is greater than a diameter of the water inlet hole 102. The water inlet hole 102 is arranged at a lower left portion that is at an angle of about 30° of the water conveying pipe 10. A rubber material is paved on the inner wall of the mounting sleeve 101 on the outer side of the water conveying pipe 10 to abut against the water conveying pipe 10. A side section of the piston plate 28 is of an “L”-shaped structural design, and a top of the piston plate 28 abuts against the inner wall of the top of the water conveying pipe 10. The piston plate 28 corresponds to the position of the water inlet 24; and two ends of the water conveying pipe 10 are blocking structures. The guide plate 29 is parallel to the pressure plate 26. Half of the guide plate 29 is designed to be a bulge structure. A movement trajectory of the bulge position of the guide plate 29 is in contact with the pressure plate 26. An end portion of the bulge position of the guide plate 29 is designed to be an inclined structure. The two-shaft motor 20 drives the guide plate 29 to rotate to push the pressure plate 26 to move. The piston plate 28 is driven to move by the transverse rod 27, to extrude the water in the water conveying pipe 10, so that the water is sprayed from the water spraying holes 104 through the water inlet hole 102 and the water guide cavity 103, to wash a pulled-apart fiber bundle.

(13) A working principle is as follows: When this one-step chitosan fiber spinning device is used, as shown in FIG. 1 to FIG. 7, a chitosan raw material is first dissolved, filtered and defoamed in a stock solution tank 2; the metering pump 4 is turned on to spray stock solution into the coagulating bath 201 through the spinning jet 3. After entering the coagulating bath 201, the stock solution is molded into a fiber bundle, and is introduced into the plasticizing stretch bath 5 through the tension rollers 9. Glycerol and aqueous solution in the plasticizing stretch bath 5 cooperate with the tension rollers 9 to perform plasticizing stretch on the fiber bundle, and then the fiber bundle enters the water washing tank 6. The two-shaft motor 20 is turned on. The two-shaft motor 20 is meshed with the gear ring 22 through the gear 21 to drive the mounting sleeve 101 to rotate clockwise on the water conveying pipe 10, and the mounting sleeve 101 drives the mounting plates 11 to rotate. When the tooth rollers 17 on the outer sides of the mounting plates 11 rotate to the position of the lower rack 18, the screws 13 are driven to rotate anticlockwise in the activity slots 12, to drive the control head seats 14 to slide outward. At this time, the control heads 15 on the control head seats 14 are plugged into the fiber bundle. As the control head seats 14 and the control heads 15 slide outward, the fiber bundle is pulled apart outward. In the pulling process, the fiber bundle is further stretched, and a small fiber bundle is stuck between two point-like bulges 16. The point-like bulges 16 and the control heads 15 are made of the rubber materials, which have certain softness. When the fiber bundle is pulled apart to a tensioning position, since the outer sides of the end portions of the control heads 15 are of inclined structures, the upper layer of fiber bundle is stretched farther away than the lower layer of fiber bundle, and the upper layer of fiber bundle is reset first. The upper layer of point-like bulge 16 has a relatively large diameter, so that the upper layer of fiber bindle is directly reset from the outer end of the lower layer of point-like bulge 16, without driving the lower fiber bundle to be reset. By this structure, the fiber bundle that is not pulled apart will not be pulled to its original position. This can achieve short-time uniform pulling of the fiber bundle. As the mounting sleeve 101 continues to rotate, the control heads 15 are disengaged from the fiber bundle, and the fiber bundle is reset, completing a transient pulling operation. When the tooth rollers 17 on the outer sides of the mounting plates 11 rotates to the upper rack 18, the tooth rollers 17 rotate clockwise, which can drive the screws 13 to rotate in a reverse direction and drive the control head seats 14 to be reset, facilitating a next operation.

(14) Next, in the process of pulling apart the fiber bundle by the control heads 15, the two-shaft motor 20 drives the guide plate 29 to rotate. The bulge position of the guide plate 29 is in contact with the pressure plate 26 to extrude the pressure plate 26, so that the pressure plate 26 drives the piston plate 28 to move in the water conveying pipe 10 through the transverse rod 27. A horizontal position on the piston plate 28 blocks the water inlet 24, and the water in the water tank 23 no longer flows into the water conveying pipe 10. The piston plate 28 then extrudes the water in the water conveying pipe 10. At this time, the water guide cavity 103 just rotates to the water inlet hole 102, so that the water in the water conveying pipe 10 enters the water guide cavity 103 through the water inlet hole 102, then enters internal cavities of the mounting plates 11 and is sprayed out through the water spraying holes 104. The water is sprayed to the pulled-apart fiber bundle, to achieve uniform water washing. As the guide plate 29 continues to rotate, the bulge position of the guide plate 29 is separated from the pressure plate 26. Under the action of the elastic telescopic rod 25, the pressure plate 26 is reset, which drives the piston plate 28 to be reset. The water inlet 24 is opened, and the water in the water tank 23 is supplemented into the water conveying pipe 10. Through the reciprocating motion of the piston plate 28, the fiber bundle is continuously pulled apart by the control heads 15, so that the fiber bundle is uniformly washed with water. At the same time, the end portions of the mounting plates 11 and the control heads 15 provide an additional tensile force to the fiber bundle, which improves the molding effect on the fiber bundle. The fiber bundle then enters the drying mechanism 7 for drying, and is wound through the winding mechanism 8.
