[0025] During operation, when the twin-screw extruder starts to run, the material is melted and mixed and extruded and transmitted toward the output end. At this time, some black matter will evaporate from the molten material. The black matter first moves from the twin-screw extruder to the inside of the second connecting tube 12, and further enters the inside of the first connecting tube 7 through the second connecting tube 12. At this time, the black matter will be blocked by the guide hat 21 and condensed into liquid under the action of the guide hat 21. At the same time, it slides downward along the inclined surface of the guide hat 21 to the lower edge of the guide hat 21, and drips into the annular receiving groove 16 under the action of its own gravity, and is collected by the annular receiving groove 16 to prevent the black matter from dripping into the material after condensation, polluting the color of the material and affecting the final quality of the finished product.

[0026] Further, such as Figure 3 and Figure 4As shown, the cleaning assembly includes a driven gear 18, which is fixedly connected to the second connecting pipe 12, a motor connecting bracket 17 is fixedly connected to the middle part of the outer side of the support tube 2, a driving motor 19 is fixedly connected to the other side of the motor connecting bracket 17, a driving gear 20 is fixedly connected to the output end of the driving motor 19, and the driving gear 20 is meshingly connected to the driven gear 18, and two cleaning scrapers 22 are fixedly connected to the lower part of the outer side of the guide hat 21, and the cleaning scrapers 22 correspond to the annular receiving groove 16.

[0027] During operation, when the black matter stored and collected inside the annular receiving groove 16 accumulates to a certain amount, the driving motor 19 is started, and the driving motor 19 drives the driving gear 20, and further transmits power through the driven gear 18 to drive the guiding hat 21 to rotate, and the cleaning scrapers 22 on both sides are driven to rotate by the guiding hat 21, so as to clean and push the black matter collected inside the annular receiving groove 16, and accelerate its discharge rate through the sewage pipe 15.

[0028] Further, such as Figure 1 As shown, an alarm 10 is fixedly connected to the top of the vacuum monitoring module 11 , and a flash light 9 is fixedly connected to the top of the alarm 10 .

[0029] During operation, the vacuum tightness inside the first connecting tube 7 is detected through the vacuum monitoring module 11. When the tightness inside the first connecting tube 7 is reduced, the alarm 10 is activated through the vacuum monitoring module 11, and an alarm is further sounded through the alarm 10. At the same time, the flash light 9 emits a bright red light to remind the staff to handle it.

[0030] Further, such as Figure 2 As shown, a first sealing O-ring 13 is sleeved on the inner upper part of the sealing cover plate 3 , a sealing groove 5 is fixedly connected to the outer upper part of the first connecting pipe 7 , and a second sealing O-ring 14 is arranged inside the sealing groove 5 .

[0031] During operation, in the process of fixing the sealing cover plate 3, the upper end of the first connecting tube 7 will squeeze the first sealing O-ring 13, and the lower end of the sealing cover plate 3 will squeeze the second sealing O-ring 14. The deformation of the first sealing O-ring 13 and the second sealing O-ring 14 further reduces the gap between the first connecting tube 7 and the sealing cover plate 3, thereby improving the overall airtightness of the equipment.

[0032] Further, such as Figure 1 As shown, the outer side of the sealing cover plate 3 is fixedly connected with equally distributed hooks 4, the outer side of the first connecting pipe 7 is fixedly connected with equally distributed buckles 6, and the equally distributed buckles 6 correspond to the equally distributed hooks 4.

[0033] During operation, the other end of the connector 1 is connected to the connecting hose 8, and the supporting tube 2 and the structure directly or indirectly connected to the supporting tube 2 are further placed into the first connecting tube 7. Then, the sealing cover plate 3 is fixed on the first connecting tube 7 by moving the buckle 6 and cooperating with the hook 4, so that the sealing cover plate 3 and the first connecting tube 7 are tightly matched.

[0034] Further, such as Figure 5 As shown, a sewage pipe 15 is connected to the lower part of the first connecting pipe 7 away from the connecting hose 8 , and the sewage pipe 15 corresponds to the annular receiving groove 16 .

[0035] During operation, the black matter stored in the annular receiving groove 16 is discharged through the drain pipe 15 to prevent the black matter in the annular receiving groove 16 from excessively flowing back and being mixed into the material.

[0036] Working principle: During the preparation process, first, connect the other end of the connector 1 to the hose 8, and then further put the support tube 2 together with the structure directly or indirectly connected to the support tube 2 into the first connecting tube 7, and then fix the sealing cover plate 3 on the first connecting tube 7 by turning the buckle 6 and cooperating with the hook 4, so that the sealing cover plate 3 and the first connecting tube 7 are tightly matched. At the same time, in the process of fixing the sealing cover plate 3, the first sealing O-ring 13 will be squeezed at the upper end of the first connecting tube 7, and the second sealing O-ring 14 will be squeezed at the lower end of the sealing cover plate 3, so as to improve the airtightness of the equipment. When the twin-screw extruder starts to run, the materials are melted and mixed and extruded and transmitted toward the output end. At this time, some black substances will evaporate from the molten material. The black substances first move from the twin-screw extruder to the inside of the second connecting tube 12, and further enter the first connecting tube 7 through the second connecting tube 12. At this time, the black substances will be blocked by the guide hat 21, and condensed into liquid under the action of the guide hat 21, and at the same time slide downward along the inclined surface of the guide hat 21 to the guide At the lower edge of the bamboo hat 21, it drips into the annular receiving groove 16 under the action of its own gravity and is collected by the annular receiving groove 16 to prevent the black matter from condensing and dripping into the material, polluting the color of the material and affecting the quality of the final product. When the black matter stored and collected in the annular receiving groove 16 accumulates to a certain amount, the driving motor 19 is started, and the driving gear 20 is driven by the driving motor 19, and the driving gear 18 is further transmitted through the driven gear 18 to drive the guiding bamboo hat 21 to rotate, and the cleaning scrapers 22 on both sides are driven to rotate by the guiding bamboo hat 21 to clean and push the black matter collected in the annular receiving groove 16, and accelerate the discharge rate through the sewage pipe 15. The other end of the connecting hose 8 is connected to the vacuum monitoring module 11, and the vacuum tightness inside the first connecting pipe 7 is detected by the vacuum monitoring module 11. When the airtightness inside the first connecting pipe 7 is reduced, the alarm 10 is started by the vacuum monitoring module 11, and an alarm is further sounded by the alarm 10. At the same time, the flashlight 9 emits a bright red light to remind the staff to handle it.

[0037] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods.
