Description

Technical Field

[0001] The invention relates to the technical field of spinning equipment, and more specifically, to a high temperature resistant ultra-high molecular weight polyethylene fiber spinning equipment. Background Art

[0002] Polyethylene fiber (PEF) refers to a fiber material obtained by melt spinning polyethylene, including short fibers and filaments. Polyethylene fiber has the advantages of high strength, low density, and good insulation. Polyethylene fiber is prepared by a wet route, and ultra-high molecular weight polyethylene spinning solution is prepared with low-volatile substances such as mineral oil and white oil as solvent. The spinning solution is extruded from the spinneret and then enters a water bath (or a mixed bath of water and ethylene glycol, etc.) to solidify to obtain a wet gel precursor containing a low-volatile solvent. The wet gel precursor is extracted with an extractant (Freon or other reagents) with high volatility and excellent extraction performance through a continuous extraction device in multiple stages. The extractant replaced in the gel precursor is fully vaporized and escaped through a continuous multi-stage drying device to obtain a dry gel precursor, which is then stretched at a high multiple to obtain a high-performance polyethylene fiber.

[0003] As an important component of the spinning equipment, the spinneret can transform the viscous polymer melt or solution into fine streams through the spinneret holes. These fine streams can be solidified by the coagulation medium to form filament bundles. The spinneret is often used in the production of synthetic fibers. In the production process of synthetic fibers, the molten polyester melt enters the spinning box through the conveying pipe, and then is extruded through the spinneret in the spinning box to form filament bundles. The filament bundles are then cooled by the coagulation medium, and finally the filament bundles are wound into shape, thus completing the production of synthetic fibers.

[0004] However, when spinning for a long time, impurities are easily adhered to the spinneret holes or material residues are likely to appear, which will cause pollution to the subsequently ejected fibers and reduce the quality of the high-performance polyethylene fibers. Summary of the invention

[0053] A water tank 50 is fixed to the side of the cleaning box 2; a piston cylinder 51 is fixed to the side of the cleaning box 2; a water collecting box 52 is fixed to the inner wall of the cleaning box 2; a plurality of water spraying pipes 53 are evenly connected to the side of the water collecting box 52; a water suction pipe is connected to the bottom of the piston cylinder 51 and the clean water tank 50; a drainage pipe 54 is connected between the piston cylinder 51 and the water collecting box 52.

[0054] A piston plate 55 is slidably arranged inside the piston cylinder 51; a piston rod 56 is fixed to the side of the piston plate 55; a side plate 57 is fixedly connected between the piston rod 56 and the slide plate 47; a one-way valve is arranged on the water suction pipe and the drainage pipe 54; a cleaning liquid inlet pipe 58 and a waste water discharge pipe 59 are successively penetrated and connected to the inner wall of the cleaning box 2 near its inner bottom surface; the cleaning liquid inlet pipe 58 and the waste water discharge pipe 59 are both provided with solenoid valves electrically connected to the output end of the controller 24.

[0055] A blower 60 electrically connected to the output end of the controller 24 is fixedly installed on the side of the cleaning box 2; an air collecting box 61 connected to the output end of the blower 60 is fixed on the inner wall of the cleaning box 2; and a plurality of exhaust pipes 62 are evenly connected and arranged on the side of the air collecting box 61.

[0056] A fixing seat 64 is fixed to the side surface of the fixing disk 17; guide holes 65 that slide with the corresponding support rods 15 are symmetrically opened on the surface of the fixing seat 64; a baffle 66 is fixed to the top of the support rod 15; a return spring 67 mounted on the support rod 15 is fixedly connected between the baffle 66 and the fixing seat 64; a number of dredging rods 68 corresponding to the spinneret holes on the corresponding spinneret plates 35 are evenly fixed at the bottom of the fixing disk 17; a number of cleaning sponge blocks 69 are evenly arranged on the side surface of the dredging rods 68 from top to bottom.

[0057] Working principle of the third embodiment:

[0058] Close the first solenoid valve on the discharge pipe 29, and control the start-up servo motor 33 to drive the rotating shaft 32 to rotate 180°, thereby driving the two groups of spinnerets 7 to rotate 180° to complete the replacement, so that the spinneret 7 that needs to be cleaned is rotated out of the disc body 4 and enters the cleaning box 2, and is placed between the two arc-shaped baffles 14. The spinneret 7 that has completed cleaning rotates into the disc body 4, completing the replacement of the two groups of spinnerets 7, which is convenient for subsequent cleaning of the relevant spinnerets 7.

[0059] like Fig.12 As shown in (a)→(b), the ball head 20 is vertically facing upward, and the stepper motor 46 is controlled to start to drive the drive shaft 43 to rotate, and the gear 45 is driven to rotate synchronously, thereby driving the arc gear ring 40 to slide along the arc guide groove 42 toward the direction close to the arc plate 11, thereby driving the connecting part 12 to slide downward, and then driving the spinneret 7 clamped between the two arc baffles 14 to rotate downward.

[0060] like Fig.12 As shown in (b) → (c), when the ball head 20 moves together with the connecting portion 12 until it abuts against the side of the vertical guide plate 22, the connecting portion 12 drives the ball head 20 to continue to move, and the ball head 20 is blocked by the vertical guide plate 22, so that the ball head 20 drives the fixed plate 17 to slide down along the corresponding support rod 15, and the reset spring 67 is compressed, so that the dredging rod 68 is inserted into the spinneret hole corresponding to the spinneret 35, and the cleaning sponge block 69 on the dredging rod 68 dredges the spinneret hole.

[0061] like Fig.12 As shown in (c) → (d), when the ball head 20 moves from the vertical guide plate 22 to the arc guide plate 21, the dredging rod 68 is continuously inserted into the spinneret hole. When the ball head 20 continues to slide down on the arc guide plate 21, the dredging rod 68 slides down. When the ball head 20 slides up on the arc guide plate 21, the elastic reset force of the reset spring 67 drives the dredging part 16 to slide up along the support rod 15, thereby driving the dredging rod 68 to slide up and disengage from the corresponding spinneret hole.

[0062] The stepping motor 46 is controlled to start and drive the driving shaft 43 to rotate in the opposite direction. The specific operation process is the same as described above and will not be repeated here.

[0063] To sum up, by controlling the drive shaft 43 to rotate forward and reverse periodically, the connecting part 12 and the corresponding spinneret disk 7 are driven to perform periodic swing cleaning inside the cleaning box 2. During this process, the reset spring 67 is cooperated to drive the clearing part 16 to perform reciprocating lifting and lowering motion along the support rod 15 on the connecting part 12, thereby realizing the reciprocating clearing operation of the spinneret holes inside the spinneret disk 7.

[0064] By controlling the drive shaft 43 to rotate forward and reverse periodically, the guide ball 49 is driven to slide back and forth along the spiral groove 44, thereby driving the slide plate 47 and the piston rod 56 to slide back and forth synchronously, and then driving the piston plate 55 to slide back and forth periodically along the inside of the piston cylinder 51. By setting a one-way valve on the water suction pipe, the water in the water tank 50 can only be pumped into the piston cylinder 51 through the water suction pipe. By setting a one-way valve on the drain pipe 54, the water inside the piston cylinder 51 can only be sent to the water collecting box 52 through the drain pipe 54 in turn, and sprayed out through each group of water spray pipes 53, so as to flush the spinneret 7 during the swinging process, thereby further improving the cleaning efficiency and effect of the spinneret 7.

[0065] Cleaning liquid is added to the cleaning box 2 through the cleaning liquid inlet pipe 58. The liquid level of the cleaning liquid is lower than the spinneret 7 in the horizontal state and higher than the spinneret 7 in the vertical state. After the cleaning of the spinneret 7 is completed, the waste water is discharged through the waste water discharge pipe 59, and the blower 60 is controlled to start. The air flow is blown to the spinneret 7 through the exhaust pipe 62, thereby improving the drying efficiency of the spinneret 7.
