However, the clean water used for cooling needs to be cooled by an external device, which increases the cost of the device. In addition, too many drive devices will increase the cost and make maintenance more difficult, making it inconvenient to use.

[0060] S2. The raw materials can be fully mixed through the mixing component. After the raw materials at the bottom are used up, the materials at the top can be discharged to the bottom for replenishing the raw materials, and a sound is emitted to remind the staff;

[0061] S3, after the pipeline is formed, it can enter the interior of the cooling box 8, and the pipeline is cooled by the cooling component;

[0062] S4. The cooling water can be stirred by the stirring component and continuously sent into the interior of the cooling component to improve the cooling effect of the device.

[0063] Working principle: When the device works normally, the servo motor 4 is started, the output shaft of the servo motor 4 drives the second rotating shaft 10 to rotate, the second rotating shaft 10 drives the extrusion screw 15 to rotate, the extrusion screw 15 can extrude the mixed raw materials, the heating cylinder 6 is started, the raw materials are heated by the electric heating wire inside the heating cylinder 6, and the extrusion screw 15 and the die head 13 are cooperated to extrude the air pressure pipeline;

[0064] At the same time, when the second rotating shaft 10 rotates, it can drive the third rotating shaft 23 to rotate through the transmission of the first synchronous wheel 20 and the first synchronous belt 21, the third rotating shaft 23 drives the second bevel gear 19 to rotate, the second bevel gear 19 drives the first bevel gear 18 to rotate, the first bevel gear 18 drives the first rotating shaft 9 to rotate, and the first rotating shaft 9 can drive the fourth rotating shaft 26 to rotate through the transmission of the second synchronous wheel 24 and the second synchronous belt 25;

[0065] When the fourth rotating shaft 26 rotates, the first stirring blade 35 and the second stirring blade 38 can be driven to rotate. The second stirring blade 38 and the first stirring blade 35 can fully mix the materials. The fixed circular plate 37 is set to divide the space inside the mixing box 5 into two spaces, the lower part is the mixed material, and the upper part is the material that has not been mixed yet. After the material enters the interior of the fixed outer cylinder 41 through the sliding inner cylinder 43, it is sequentially fed into the interior of the extruder housing 12 through the first feeding port 11 and the second feeding port 16;

[0066] When the material below is slowly discharged, the weight of the material on the sliding circular plate 39 gradually decreases. At this time, the sliding circular plate 39 moves upward under the elastic force of the spring 40, and because the sliding inner cylinder 43 is inside the fixed outer cylinder 41, the material will not leak out at this time. The sliding circular plate 39 can drive the fourth rotating shaft 26 to move upward, and the fourth rotating shaft 26 drives the cylindrical block 46 and the frustum block 47 to move upward. The cylindrical block 46 moves from the inside of the feed port 45 to the outside of the feed port 45. When the frustum block 47 is located inside the feed port 45, the feed port 45 is blocked.

[0067] At this time, the material above the fixed circular plate 37 moves to the bottom of the fixed circular plate 37, completing the automatic feeding process. The weight above the sliding circular plate 39 gradually increases. At this time, the cylindrical block 46 moves down again. The cylindrical block 46 can block the feed port 45 again, and the material will make a sound when it falls quickly, which can remind the staff and facilitate the staff to add materials in time, thereby avoiding the situation where the production process stops.

[0068] At this time, the staff can first move the two U-shaped fixing frames 30 upward to ensure the stability of the two sliding cover plates 28, and then move the sliding cover plates 28 horizontally to open the two sliding cover plates 28, so that the staff can add materials conveniently, and the materials above have been mixed completely, and no longer need time to mix after falling, which can prevent the incompletely mixed materials from entering the interior of the extruder housing 12;

[0069] The extruded pipe will enter the interior of the cooling box 8 through the pipe inlet 60. The plurality of pads 59 can support the pipe. The pipe is finally discharged through the pipe outlet 58. Since the cooling box 8 drains water at a slow speed, the interior of the cooling box 8 is always full, so the pipe can be cooled. The overflowed water will enter the interior of the water storage tank 2.

[0070] When the third rotating shaft 23 rotates, it drives the internal reciprocating screw 63 to rotate. When the reciprocating screw 63 rotates, it can drive the piston plate 66 to reciprocate inside the hollow tube 7, and then the water inside the water storage tank 2 can be pumped into the hollow tube 7 through the water inlet pipe 49. Since a one-way valve is provided inside the water outlet pipe 65, the water will be discharged through the water outlet pipe 65 and the nozzle 64 to cool the pipeline. When the piston plate 66 returns, the remaining water inside can be discharged through the water outlet pipe 65 and the nozzle 64 to cool the pipeline again, thereby improving the cooling effect.

[0071] When the third rotating shaft 23 is rotating, it can drive the elliptical plate 48 to rotate. The short side and the long side of the elliptical plate 48 constantly conflict with the L-shaped rods 56 on both sides, thereby pushing the two L-shaped rods 56 away from each other. The L-shaped rod 56 stretches the tension spring 57 and drives the two racks 55 away from each other. The rack 55 drives the spur gear 54 to swing, the spur gear 54 drives the round rod 51 to swing, and the round rod 51 drives the rectangular rod 52 and the paddle 53 to swing, thereby increasing the contact area between the clean water and the air inside the water tank 2, improving the heat exchange efficiency, and ensuring the cooling effect on the pipeline.

[0072] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
