[0040] An operating method of a high-efficiency hot melting extrusion device for nylon fibers, comprising the following steps:

[0041] S1. Control the rotating disc 4 to drive the extrusion cylinder 5 to rotate to the vertical state, so that the two ends of the extrusion cylinder 5 are respectively communicated with the first through holes 7 on the upper and lower sides, at this time, continue to drive the conveying screw 6 to rotate, so that the molten raw material in the extrusion cylinder 5 is vertically extruded from the bottom to the conveying mechanism 42;

[0042] S2. The extruded product is conveyed in the cooling liquid in the cooling box 1 through the conveying mechanism 42, which avoids product accumulation and improves the efficiency of cooling and forming;

[0043] S3. Control the rotating disc 4 to drive the extrusion cylinder 5 to rotate to the horizontal state, so that the two ends of the extrusion cylinder 5 are respectively communicated with the second through holes 8 on the two sides, so as to cut off the conveying state of the molten raw material, and at the same time, the cutting knife 10 is linked to cut and separate the bottom extruded raw material and product, at this time, the conveying screw 6 is pulled out from the second through holes 8 on the two ends, so as to be cleaned and replaced.

[0044] In this embodiment, in the initial state, the extrusion cylinder 5 is in a horizontal state, and the two ends are connected with the second through hole 8. The two sets of sleeve sleeves 19 and the conveying screw 6 are inserted into the extrusion cylinder 5 from the second through hole 8 on both sides, so that the sleeve sleeve 19 is inserted with the plug-in rod 14, and the required extrusion head 23 is connected and fixed with the threaded pipe 22. After the required raw materials are injected into the hot melting barrel 21 for melting, after the mixing and melting are completed, the driving motor 40 is started to drive the driving shaft 11 to rotate clockwise, the driving shaft 11 drives the first bevel gear 17 to make the second bevel gear 18 rotate. At this time, due to the uniform friction between the driving shaft 11 and the inner wall of the rotating disc 4, the rotating disc 4 will preferentially rotate slowly in the fixed cylinder 3. The limiting block 29 rotates in the arc-shaped groove 28 until it reaches the other end of the arc-shaped groove 28. At this time, the rotating disc 4 is just rotated by 90°, and the extrusion cylinder 5 is rotated to the vertical state, and the two ends are respectively connected with the first through hole 7. The molten raw materials in the hot melting barrel 21 can be conveyed downward into the extrusion cylinder 5.

[0045] The second bevel gear 18 drives the limiting disc 13 and the plug-in rod 14 to rotate, so that the upper and lower two sets of conveying screws 6 rotate. The screw directions of the two sets of conveying screws 6 are opposite, so as to ensure that the raw materials are always pushed downward to the extrusion head 23 during opposite direction rotation, and the extrusion operation is performed. The pressure distribution of the raw materials in the threaded pipe 22 is relatively uniform, and at the same time, the driving shaft 11 rotates to drive the transmission belt 39 to drive the driving roller 24 to drive the conveying belt 9 to transmit, so that the rotating rod 25 continuously passes through the bottom of the extrusion head 23, supports and salvages the strip-shaped products extruded into the cooling box 1, and the products are cooled and conveyed in the cooling liquid, thereby improving the molding efficiency.

[0046] When the conveying belt 9 performs forward product conveying, the transmission direction of the conveying belt 9 is the same as the direction of the inclined surface at the bottom of the inclined tooth block 32. The conveying belt 9 is driven by the tension of the clock spring 38 to drive the winding cloth 37 to pull the connecting rod 31, so that the sliding block 30 drives the cutting knife 10 to move away from the area of the extrusion head 23, avoiding blocking the extruded products, and also avoiding blocking the conveying of the products in the cooling box 1.

[0047] Conversely, when the extrusion operation is completed, the driving motor 40 drives the driving shaft 11 to rotate reversely, so that the rotating disc 4 and the extrusion cylinder 5 rotate reversely, the limiting block 29 rotates to the other end of the arc-shaped groove 28, the extrusion cylinder 5 is out of the communication state with the first through hole 7, the raw material in the hot melt bucket 21 no longer continues to flow downward, at the same time, the driving shaft 11 drives the transmission belt 39 to drive the driving roller 24 to rotate reversely, the conveying belt 9 is in contact with the bottom tip of the bevel tooth block 32, drives the bevel tooth block 32 to slide together with the sliding block 30, so that the cutting knife 10 slides to the bottom of the extrusion head 23, thereby cutting the strip-shaped product at the bottom of the extrusion head 23, and the connecting rod 31 moves one end of the winding cloth 37 to block the bottom of the extrusion head 23, the winding disc drives the connecting shaft 36 to rotate, and the clockwork spring 38 is compressed, when the two ends of the extrusion cylinder 5 are communicated with the second through hole 8, the driving shaft 11 stops rotating, and the equipment is reset.

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

[0049] It should be noted that, in the present document, relational terms such as first and second and the like can be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.
