[0002] The scientific name of nylon fiber is polyamide fiber. It was originally the trade name of polyhexamethylene adipamide produced by DuPont. It is the first synthetic fiber product commercialized from synthetic polymers, thus opening the first page of synthetic fibers. It is still the representative of polyamide fiber. In the process of nylon fiber production, extrusion equipment is needed to extrude the hot melt produced by the processing and melting of raw materials into strips, and then through subsequent processing, nylon fibers are manufactured.

[0003] Existing hot melt extrusion equipment for nylon fibers mostly uses a horizontally rotating conveying screw to extrude. Due to the influence of the liquid's own gravity, the pressure of the material extruded from the bottom is often greater than the pressure of the material extruded from the upper through hole during the extrusion process. At the same time, after the extrusion is completed, the internal conveying screw is fixed in position, and cleaning and disassembly are not convenient and efficient, which causes the molten liquid to solidify easily inside the equipment, affecting subsequent use.

[0040] A method for operating a hot-melt high-efficiency extrusion device for nylon fibers comprises the following steps:

[0041] S1. Control the rotating disk 4 to drive the extrusion barrel 5 to rotate to a vertical state, so that the two ends of the extrusion barrel 5 are connected to the first through holes 7 on the upper and lower sides respectively, and then continue to drive the conveying screw 6 to rotate, so that the molten raw material in the extrusion barrel 5 can be vertically extruded from the bottom to the conveying mechanism 42;

[0042] S2. The extruded product is transported in the coolant in the cooling box 1 by the conveying mechanism 42 to avoid product accumulation while improving the efficiency of cooling and molding;

[0043] S3. Control the rotating disk 4 to drive the extrusion barrel 5 to rotate to a horizontal state, so that the two ends of the extrusion barrel 5 are respectively connected to the second through holes 8 on both sides, thereby cutting off the conveying state of the molten raw material. At the same time, the cutting knife 10 is linked to cut and separate the raw material and the product extruded from the bottom. At this time, the conveying screw 6 can be pulled out from the second through holes 8 at both ends for cleaning and replacement.

[0044] In this embodiment, in the initial state, the extrusion barrel 5 is in a horizontal state, and both ends are connected to the second through hole 8. Two sets of sleeve barrels 19 and conveying screws 6 are respectively inserted into the extrusion barrel 5 from the second through holes 8 on both sides, so that the sleeve barrel 19 is plugged into the plug-in rod 14, and the required extrusion head 23 is replaced with the threaded tube 22 for connection and fixation, and the required raw materials are injected into the hot melt barrel 21 for melting. After the mixed melting is completed, the drive motor 40 is started to drive the drive shaft 11 to rotate clockwise, and the drive shaft 11 drives the first bevel gear 17 to rotate the second bevel gear 18. At this time, due to the uniform friction between the drive shaft 11 and the inner wall of the rotating disk 4, the rotating disk 4 will preferentially rotate slowly in the fixed barrel 3, and the limit block 29 rotates in the arc groove 28 until it reaches the other end of the arc groove 28. At this time, the rotating disk 4 just rotates 90°, and the extrusion barrel 5 rotates to a vertical state, and both ends are respectively connected to the first through hole 7, so that the molten raw material in the hot melt barrel 21 can be transported downward into the extrusion barrel 5.

[0045] The second bevel gear 18 drives the limit plate 13 and the plug-in rod 14 to rotate together, so that the upper and lower groups of conveying screws 6 rotate. The spiral directions of the two groups of conveying screws 6 are opposite, thereby ensuring that the raw material is always pushed downward to the extrusion head 23 when rotating in opposite directions for extrusion operation. The pressure distribution of the raw material in the threaded tube 22 is relatively uniform. At the same time, when the driving shaft 11 rotates, it will drive the transmission belt 39 so that the driving roller 24 drives the conveyor belt 9 for transmission, so that the rotating rod 25 continuously passes through the bottom of the extrusion head 23, and the strip products extruded into the cooling box 1 are supported, salvaged and conveyed. The products are cooled and conveyed in the coolant to improve the molding efficiency.

[0046] When the conveyor belt 9 is conveying the product in the forward direction, the transmission direction of the conveyor belt 9 is the same as the direction of the inclined surface at the bottom of the bevel tooth block 32. Under the pulling force of the clockwork spring 38, the winding cloth 37 is driven to pull the connecting rod 31 so that the sliding block 30 drives the cutting knife 10 to move to an area away from the extrusion head 23, avoiding blocking the extruded product and also not blocking the transportation of the product in the cooling box 1.

[0047] On the contrary, when the extrusion operation is completed, the driving motor 40 drives the driving shaft 11 to rotate in the opposite direction, so that the rotating disk 4 and the extrusion cylinder 5 rotate in the opposite direction, the limit block 29 rotates to the other end of the arc groove 28, and the extrusion cylinder 5 is released from the connection state with the first through hole 7. The raw material in the hot melt barrel 21 no longer continues to flow downward, and the driving shaft 11 drives the transmission belt 39 to make the driving roller 24 rotate in the opposite direction. The conveyor belt 9 contacts the bottom tip of the bevel gear block 32, driving the bevel gear block 32 and the sliding block 30 to slide together, so that the cutting knife 10 slides toward the bottom of the extrusion head 23, thereby cutting off the strip product at the bottom of the extrusion head 23, and the connecting rod 31 will pull one end of the winding cloth 37 to move, blocking the bottom of the extrusion head 23, and the winding disk drives the connecting shaft 36 to rotate, and the clockwork spring 38 is compressed. When the two ends of the extrusion cylinder 5 are connected with the second through hole 8, the driving shaft 11 stops rotating, and the equipment is reset.

[0048] At this time, the strip products in the cooling box 1 can be fished out and stored, and the conveying screw 6 in the extrusion cylinder 5 can be taken out from the second through holes 8 at both ends. Since the inner diameter of the first through hole 7 is smaller than the outer diameter of the conveying screw 6, the inner diameter of the second through hole 8 is not smaller than the outer diameter of the conveying screw 6, so that when the conveying screw 6 is in a vertical state, the conveying screw 6 will not slide into the first through hole 7, and when the conveying screw 6 is in a horizontal state, the conveying screw 6 can be taken out from the second through hole 8 for cleaning and replacement. At this time, there are only the plug-in rod 14, the device box 12 and the drive shaft 11 inside the extrusion cylinder 5, without too many corners and bends, and it can be directly rinsed, which is more convenient for cleaning the equipment.
