Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. The present invention is further described below in combination with the embodiments.

[0044] See also Figure 1 as well as Figure 2In one embodiment of the present application, a novel annular bellows for mining includes a bellows body 1, a connector 2 and a receiving channel 4, wherein the connector 2 and the receiving channel 4 are respectively arranged at both ends of the bellows body 1, and the connector 2 and the receiving channel 4 are respectively provided with external threads and internal threads that match each other, and the annular bellows also includes:

The partition 28 is arranged in the spiral tube 16 and is located on one side of the through hole 29. A negative pressure area is formed between the partition 28 and the through hole 29.

[0064] In actual application, metal powder and additives are fed into the primary mixing chamber 20 along the feed pipe 19, and the air pump 22 works to feed air into the spiral tube 16 along the drive pipe 21, and the air is finally discharged from the output head 17. Since the spiral tube 16 is provided with a plurality of uniformly arranged air nozzles 26, and according to the attached Figure 5As shown, the direction of the air nozzle 26 is not pointing to the center of the circle, so that negative pressure is generated in the negative pressure area, and the air in the primary mixing chamber 20 can be sucked into the spiral tube 16, so that a vortex airflow is generated in the primary mixing chamber 20. Under the action of gravity, the metal powder and the additive rotate and move downward with the vortex airflow, so that the additive and the metal powder are fully and evenly mixed together. Compared with the traditional method of directly stirring with stirring blades, the present device can disperse the bulk of the incoming material under the action of the vortex airflow and fully mix it with the additive powder, avoiding uneven mixing and affecting the quality of the subsequent production of the annular corrugated pipe.

[0066] In this embodiment, the trigger module includes a trigger box 34, a slide plate 32, a monitoring element, an exhaust hole 35 and a solenoid valve 36;

[0067] The trigger box 34 is arranged on the hot melt box 25 and is connected to the output head 17. The slide plate 32 is movably arranged in the trigger box 34 and the two are elastically connected. The monitoring element is arranged between the slide plate 32 and the trigger box 34 and can monitor the position of the slide plate 32. The exhaust hole 35 is arranged in the trigger box 34. The solenoid valve 36 is arranged in the exhaust hole 35. The control valve box 24 and the solenoid valve 36 are both electrically connected to the monitoring element.

[0068] It should be specifically explained that the monitoring element includes two conductive sheets 33 , and the conductive sheets 33 are disposed on the opposite surfaces of the slide plate 32 and the trigger box 34 .

[0069] It should be noted that the monitoring element is not limited to the above-mentioned mechanical structure, and may also be replaced by an infrared ranging sensor or a laser ranging sensor, which are not listed here one by one.

[0072] There are several sleeves 13 and they are arranged in the middle position of the main stirring blade 12. The rotating shaft 14 is movably arranged in the mixing box 10. The sleeve 13 is movably sleeved on the outer wall of the rotating shaft 14. There are several auxiliary stirring blades 15 and they are evenly arranged on the rotating shaft 14.

The stepper motor 11 can drive the main stirring blade 12 to rotate in the forward direction, and when the air pump 22 works to input air flow into the driving pipe 21, it can drive the rotor 23 to rotate. The rotor 23 drives the rotating shaft 14 and the auxiliary stirring blade 15 to rotate in the opposite direction. The main stirring blade 12 and the auxiliary stirring blade 15 rotate in opposite directions, thereby improving the mixing and stirring effect of the metal powder and the additive in the mixing box 10, so that the two are fully and evenly mixed together, and when the rotating shaft 14 rotates, it can drive the crushing roller 18 to rotate.

The best choice is made based on the actual application situation, and no specific explanation is given here.

[0076] How this application works:

[0077] When installing and connecting multiple annular bellows, the connector 2 of one bellows is inserted into the receiving channel 4 of another bellows and rotated. Under the cooperation between the internal thread and the external thread, the two bellows can be connected and fixed. When the connector 2 enters the receiving channel 4 and meets the contact plate 6, the contact plate 6 can be driven to Figure 2 The piston 7 is moved to the left in the direction shown, thereby driving the piston 7 to move in the cavity through the connecting rod 8, squeezing the air in the cavity into the airbag 9, causing the airbag 9 to expand and extend into the recess 3, thereby improving the sealing degree between the connector 2 and the receiving channel 4.

[0078] The metal powder and additives are fed into the primary mixing chamber 20 along the feed pipe 19, and the air pump 22 works to feed the air flow into the spiral tube 16 along the drive pipe 21, and the air flow is finally discharged from the output head 17. Since the spiral tube 16 is provided with a plurality of uniformly arranged air nozzles 26, and according to the attached Figure 5 As shown, the direction of the air nozzle 26 is not toward the center of the circle, so that negative pressure is generated in the negative pressure area, and the air in the primary mixing chamber 20 can be sucked into the spiral tube 16, so that a vortex airflow is generated in the primary mixing chamber 20. Under the action of gravity, the metal powder and the additive rotate and move downward with the vortex airflow, so that the additive and the metal powder are fully and evenly mixed together. Compared with the traditional method of directly stirring with stirring blades, the present device can disperse the bulk of the incoming materials under the action of the vortex airflow and fully mix them with the additive powder, avoiding uneven mixing and affecting the quality of the annular bellows produced subsequently. Finally, the preliminarily mixed mixed material is discharged into the bottom of the mixing box 10 and is driven by the stepper motor 1 1 can drive the main stirring blade 12 to rotate in the forward direction, and when the air pump 22 is working and inputs airflow into the driving pipe 21, it can drive the rotating blade 23 to rotate, and the rotating blade 23 drives the rotating shaft 14 and the auxiliary stirring blade 15 to rotate in the opposite direction. The main stirring blade 12 and the auxiliary stirring blade 15 rotate in opposite directions, thereby improving the mixing and stirring effect of the metal powder and additives in the mixing box 10, so that the two are fully and evenly mixed together, and when the rotating shaft 14 rotates, it can drive the grinding roller 18 to rotate. Through the cooperation between the grinding roller 18 and the inner wall of the grinding chamber 37, the large-particle material passing through can be ground and crushed, so as to avoid the large-volume material from affecting the quality of the subsequent production of the annular corrugated pipe. The airflow in the spiral tube 16 is input into the trigger box 34 along the output head 17. Under the impetus of the airflow, it can drive the slide plate 32 to Figure 7The conductive sheet 33 is moved rightward in the direction shown until the conductive sheets 33 are in contact with each other. On the one hand, the electromagnetic valve 36 is triggered to be energized and opened, so that the air in the trigger box 34 is discharged. On the other hand, the control valve box 24 can be triggered to work, so that the material in the mixing box 10 is discharged into the hot melt box 25 for melting treatment, thereby realizing intermittent discharge of the mixture in the mixing box 10 without manual control by the staff. Finally, the molten material is discharged into the molding device 31 and extruded into an annular corrugated tube.
