[0022] like Figure 1-3 As shown, a raw material extrusion device for yarn production includes a hot melt extrusion mechanism 1. A feeding funnel 2 is mounted above the hot melt extrusion mechanism. The lower end of the feeding funnel is connected to the input end of the hot melt extrusion mechanism via a feeding pipeline system 3. Several distributors 5 are connected to the output end of the hot melt extrusion mechanism via a discharge pipeline system 4. Several discharge ports are provided on the distributors. In use, granular material is fed into the feeding funnel, fed into the hot melt extrusion mechanism for hot melting and mixing through the feeding pipeline system, and then extruded into the discharge pipeline system through the hot melt extrusion mechanism. Finally, it is sent into the distributors and then into the next-level production equipment through the distributors.

[0023] In this embodiment, for ease of loading, the feeding funnel and the hot-melt extrusion mechanism are located on different adjacent floors for convenient feeding. Simultaneously, symmetrical flip-top plates 6 are arranged on the left and right sides of the feeding funnel to close the upper end of the funnel. Flip-top driving mechanisms 7 are arranged on the left and right sides of the feeding funnel to drive the flip-top plates to flip. One edge of each flip-top plate is hinged to the edge of the feeding funnel. The flip-top driving mechanism includes a flip-top fixing bracket 8, under which a flip-top driving cylinder 9 is hinged. The telescopic end of the flip-top driving cylinder is hinged to the flip-top plate. By extending or retracting the telescopic end of the flip-top driving cylinder, the two flip-top plates can be opened or closed, facilitating the closing of the feeding funnel when not in use and preventing safety accidents.

[0024] In this embodiment, to achieve the hot melting and conveying of granular materials, the hot melting extrusion mechanism includes an auger device 10. The auger device includes a base 11, on which an auger conveying pipe 12 is mounted. An auger shaft 13 is rotatably connected inside the auger conveying pipe, and auger blades 14 are arranged outside the auger shaft to drive the material movement. An auger motor 15 for driving the auger shaft to rotate is mounted on one end of the auger conveying pipe on the base. The other end of the auger conveying pipe is connected to a distributor. The end of the auger conveying pipe where the auger motor is mounted is closed, and one end of the auger shaft extends through the closed end and is connected to the auger motor. The auger shaft is driven to rotate by the auger motor to transport the granular material. The auger conveying pipe has a feed port on the outer wall near the auger motor. The feed port is connected to the lower end of the feeding funnel through the feeding pipeline system. The hot melt extrusion mechanism also includes a hot melt device 16. The hot melt device includes a hot melt shell 17, which is used to isolate the hot melt pipe from the outside to avoid safety accidents. A hot melt pipe 18 is horizontally placed inside the hot melt shell. The hot melt pipe is sleeved on the auger conveying pipe. An existing electric heating tube 19 is wound inside the hot melt pipe and outside the auger conveying pipe. The electric heating tube heats the auger conveying pipe to achieve the hot melt of the granular material.

[0025] In this embodiment, in order to realize the material transportation between the feeding hopper and the auger conveying pipe, the discharge pipeline system includes a discharge pipe 21 with a switch valve 20. The inlet of the discharge pipe is screwed to the lower end of the feeding hopper via a flange. That is, both the inlet of the discharge pipe and the lower end of the feeding hopper are provided with flanges, and the two flanges are connected by bolts. The outlet of the discharge pipe is connected to the inlet of the auger conveying pipe. In use, the switch valve is opened, and the material in the feeding hopper falls to the auger conveying pipe by gravity, thus realizing the material transportation between the feeding hopper and the auger conveying pipe.

[0026] In this embodiment, to prevent material blockage at the interface between the outlet of the feed pipe and the inlet of the auger conveyor pipe due to accumulation, a horn pipe 22 is provided between the outlet of the feed pipe and the inlet of the auger conveyor pipe. The small opening of the horn pipe is screwed to the lower end of the feed funnel via a flange, and the large opening of the horn pipe is screwed to the inlet of the auger conveyor pipe via a flange. That is, flanges are provided at the small opening of the horn pipe, the lower end of the feed funnel, the large opening of the horn pipe, and the inlet of the auger conveyor pipe, and the two flanges are connected by bolts.

[0027] In this embodiment, in order to observe whether there is material blockage at the interface between the outlet of the feed pipe and the inlet of the auger conveying pipe, a transparent observation tube 23 is sandwiched between the outlet of the feed pipe and the small opening of the auger pipe. Annular grooves 24 are respectively provided on the outlet of the feed pipe and the small opening of the auger pipe corresponding to the upper and lower ports of the transparent observation tube. That is, the transparent observation tube is clamped between the two annular grooves. The flanges of the outlet of the feed pipe and the small opening of the auger pipe are connected by long bolts.

[0028] In this embodiment, in order to open and close the feed pipe, the switch valve includes an upper valve body plate 25 and a lower valve body plate 26 spaced apart vertically. The three sides of the upper and lower valve body plates are sealed by a connecting plate. An insert plate 27 is slidably connected between the unsealed sides of the upper and lower valve body plates. The insert plate is slidably connected to the upper and lower valve body plates. The upper and lower valve body plates are respectively provided with valve ports for connecting the feed pipe. The valve ports on the upper and lower valve body plates are separated by the insert plate. When it is necessary to open, the insert plate can be slid out.

[0029] In this embodiment, to reduce the need for manual approach to the equipment and minimize the possibility of safety hazards, a sliding cylinder 28 for driving the slide plate is provided on the upper valve body plate. The cylinder sleeve of the sliding cylinder is fixed to the upper valve body plate, and a sliding rod 29 is provided at the middle of the outer end of the slide plate. The telescopic end of the sliding cylinder and the end of the sliding rod are connected by a connecting block 30. The sliding of the slide plate is achieved by extending and retracting the telescopic end of the sliding cylinder, eliminating the need for manual approach to the equipment and reducing the possibility of safety hazards.

[0030] In this embodiment, to achieve the conveying between the hot-melt extrusion mechanism and the distributor, the discharge pipeline system includes a discharge pipe 31. The input end of the discharge pipe is connected to the output end of the auger conveyor pipe. A pipe connector 32 is connected to the output end of the auger conveyor pipe. The input end of the discharge pipe is connected to the output end of the auger conveyor pipe through the pipe connector. A temperature sensor can be installed on the pipe connector to monitor whether the temperature of the hot-melted material meets the standard. The distributor is a housing with a storage cavity. The distributor has a melt inlet 33 connected to the output end of the discharge pipe. The distributor has several melt outlets 34. The melt outlets are equipped with electromagnetic switch valves 35. As the auger shaft rotates in the auger conveyor pipe, the hot-melted material is continuously extruded and then fed into the discharge pipe and finally into the distributor. The opening and closing of the melt outlets is achieved by the electromagnetic switch valves, thereby realizing the feeding of materials to the downstream equipment.

[0031] In this embodiment, in order to reduce heat dissipation during the conveying process and cause the melted material to cool and solidify, an insulation layer is applied to the outer wall of the discharge pipe and the distributor. The insulation layer is formed by applying existing insulation coating to the outer wall of the discharge pipe and the distributor.
