[0022] Based on Embodiment 3, the automatic control component 9 comprises, with reference to Fig. 1, Fig. 6 and Fig.7 of the description, a fixed bracket 91. The outer surface of the fixed bracket 91 is firmly connected to the outer surface of the shell 2. The outer surface of the fixed bracket 91 is firmly connected to sliding sleeves 92. The sliding sleeve 92 is made of a pressure-resistant and wear-resistant material. The inside of the sliding sleeve 92 is slidably connected to a folding rod 93. The folding rod 93 is made of a pressure-resistant and wear-resistant material. The outer surface of the folding rod 93 is firmly connected to the outer surface of the air intake pipe 8.

The temperature sensor plate is in contact with the shell 2 and is located at a position close to the nozzle position and is electrically connected to the external control circuit.

The outer surface of the sleeve 95 penetrates and is fixedly connected to the body of the fixed bracket 91. The outer surface of the thermal sensor plate 94 is fixedly connected to a Jinlun gas bag 910. The Jinlun gas bag 910 is made of a material that is resistant to stretching, fatigue, temperature, and wear, and is filled internally with an active gas. The outer surface of the Jinlun gas bag 910 is movably connected to the inside of the sleeve 95.The outer surface of the Jinlun airbag 910 is fixedly connected to a pressure plate 96. The pressure plate 96 is made of a material that is resistant to pressure and wear. The outer surface of the push plate 96 is slidably connected to the inner side of the sleeve 95. The body of the sleeve 95 is provided with a continuous sliding groove 97. The outer surface of the push plate 96 is provided with push rods 98. Two sides of the outer surface of the push rod 98 are each rotatably connected to a rotary bracket 99. The rotary bracket 99 comprises a U-shaped bracket and a fixed shaft.

By providing the automatic control component 9, the temperature at the nozzle position is detected by the thermal sensor plate 94 to control the power of the heater fan 11 to control the wind force, and at the same time, the expansion and contraction of the Jinlun gas bag 910 is controlled, and the distance between one end of the air intake pipe 8 and the nozzle position is controlled to ensure the quality of the spin molding.

[0023] In the meantime, the contents not described in detail in this specification all belong to the state of the art, which is well known to those skilled in the art.

[0024] During operation, the raw material is first heated by the spinning mechanism 1 and sprayed through the spinneret. At the same time, the air near the connecting block 3 is sucked in through the main duct 4 by the heating fan 11, heated, and then pumped into the interior of the shell 2 through the heat pipe 6 and sprayed around the spinning to assist spinning. As the air flows through the main duct 4, the stop plate 710 is sucked closer to the connecting block 3 and seals the outer opening of the main duct 4.At the same time, the stopper plate 710 drives the rack 77 through the connecting plate 79 and the connecting rod 78 to slide it into the inner cavity 74, and by the meshing of the rack 77 and the gear 76, the 8121 sealing plates 72 are driven to rotate via the rotating shafts 73 so that they are not stacked on each other, so that the two sides of the auxiliary duct 5 communicate with each other, so that the auxiliary airflow around the connecting block is taken in by the heater fan 11 through the air intake pipe 8, the heat protection hose 10 and the auxiliary duct 5, and then sprayed out by heating to enable reuse of the auxiliary hot airflow, which reduces heat loss and thus reduces processing costs.

[0025] Meanwhile, the thermal sensor plate 94 monitors the temperature around the spinning. At the same time, the internal resistance of the thermal sensor plate changes, generating an electrical signal through the current change. The thermal conduction plate conducts heat to heat the active gas inside the Jinlun gas bag 910. When the temperature is high, the gas inside the Jinlun gas bag 910 expands. The expansion of the shape of the Jinlun gas bag 910 pushes the pressure plate 96 into the sleeve 95, causing the folding rods 93 to move through the push rods 98 to move one side of the air intake pipe 8 away from the spinning area. At the same time, the power of the heating fan 11 is increased to increase the suction force and ensure the recovery of the hot air flow.When the temperature is low, the Jinlun gas bag 910 contracts, causing the push plate 96 to move, and the folding rods 93 are pulled by the push rods 98 to move, so that one end of the air suction pipe 8 approaches the spinning position, and at the same time, the power of the heating fan 11 is reduced to reduce the wind force and prevent the outside air from quickly flowing near the spinning position, resulting in a rapid drop in temperature and deterioration of the molding quality.

[0026] It should be noted that the materials of the above-mentioned 8121 sealing plate, 8121 filter element, and 8121 rubber ring are all made of 8121 polyimide-based composite material, which has excellent structural performance and durability. The structure of the Jinlun gas bag is also an existing product in this field, so its structural details will not be further described here.

[0027] Although the preferred embodiments of the present application have been described, those skilled in the art may make additional changes and modifications to these embodiments after understanding the basic creative concept. Of course, those skilled in the art may make various modifications and variations to the present application without departing from the spirit and scope of the present application.
