In addition, in the description of the present invention, unless otherwise stated, the meaning of "a plurality of" is two or more.

[0025] As Figures 1 to 7 shown, the present invention provides an embodiment of a material pipeline commutation device, including a housing 1. A main pipe orifice 2 and three auxiliary pipe orifices 3 are provided on the housing 1. The main pipe orifice 2 penetrates and fixes a core 4. The inner wall of the core 4 is an arc surface. An inner plate 5 is formed by the extension of the inner wall of the core 4. The inner plate 5 is an arc plate. The outer wall of a rotating core 6 fits the inner wall of the core 4 and is slidably connected to the core 4. A first through hole 7 is provided on the rotating core 6. The axis of the first through hole 7 and the axis of the auxiliary pipe orifice 3 are perpendicular to the rotation axis of the rotating core 6. The axis of the first through hole 7 and the axis of the auxiliary pipe orifice 3 intersect with the rotation axis of the rotating core 6. The axis of the first through hole 7 and the axis of the auxiliary pipe orifice 3 are in the same plane, so that after the rotating core 6 rotates, the first through hole 7 can be coaxial with any one of the auxiliary pipe orifices 3. The discharging mechanism includes a discharging pipe 8, and the discharging pipe 8 is slidably installed in the first through hole 7;

[0026] A rotating mechanism is used to drive the rotation of the rotating core 6. The rotating mechanism includes a rotating motor 9 and a support plate 10. The support plate 10 is a circular plate. The rotating core 6 is fixed on the support plate 10. The output shaft of the rotating motor 9 penetrates the housing 1 and then connects to the center of the support plate 10;

[0027] A concave surface 11 is formed by the inward concavity of the side wall of the rotating core 6 on the side facing the main pipe orifice 2. The concave surface 11, the inner wall of the core 4, the upper surface of the support plate 10, and the inner top surface of the housing 1 form a material cavity. The material cavity communicates with the main pipe orifice 2 and the discharging pipe 8. The setting of the material cavity can store part of the material. When the rotation of the rotating core 6 causes the discharging pipe 8 to be unable to discharge, the material can be temporarily stacked in the material cavity and then discharged from the discharging pipe 8 after the rotating core 6 completes the turning, preventing the material from accumulating in the main pipe orifice 2 and blocking the main pipe orifice 2. The turning action of the rotating core 6 can drive the movement of the material in the material cavity, preventing the material from being blocked in the material cavity. A support ring 12 is provided at the bottom of the support plate 10, and the support ring 12 is fixed on the inner wall of the core 4. On the one hand, the support ring 12 can be used to support the support plate 10, and at the same time, it can seal the gap between the support plate 10 and the inner wall of the core 4, increasing the sealing performance of the material cavity and preventing the leakage of the material.

[0028] The discharging mechanism further includes a sealing block 13, a spring 14 and a resisting plate 15. The sealing block 13 is sleeved on the discharging pipe 8, and the sealing block 13 is in sliding seal with the discharging pipe 8. The sealing block 13 is welded to the rotating core 6. A second through hole 16 is formed in the resisting plate 15, and one end of the discharging pipe 8 is fixed in the second through hole 16. The spring 14 is sleeved on the discharging pipe 8, and both ends of the spring 14 abut against the sealing block 13 and the resisting plate 15;

[0029] A plurality of sealing holes 18 are formed in the sealing plate 17 corresponding to the auxiliary pipe orifice 3. The sealing holes 18 communicate with the auxiliary pipe orifice 3. One side of the sealing plate 17 abuts against the inner wall of the housing 1, and the other side of the sealing plate 17 abuts against the resisting plate 15. That is, the resisting plate 15 is pushed by the spring 14 to abut against the sealing plate 17. The axis of the discharging pipe 8, the axis of the sealing hole 18 and the axis of the auxiliary pipe orifice 3 are located in the same plane. After rotating the rotating core 6, the discharging pipe 8 can communicate with any one of the sealing holes 18, facilitating the material to enter the auxiliary pipe orifice 3 from the discharging pipe 8. The resisting plate 15 always abuts against the sealing plate 17 during rotation. That is, during the commutation process, the outlet of the discharging pipe 8 is sealed by the sealing plate 17 to prevent material leakage during the commutation process. A sealing ring 19 is arranged around the second through hole 16, and the sealing ring 19 is used to seal the gap at the abutting portion between the second through hole 16 on the resisting plate 15 and the sealing hole 18;

[0030] The outer wall of the fixed core 4 is an arc surface. An outer plate 20 is formed by extending the outer wall of the fixed core 4. The outer plate 20 is an arc plate. The edge of the outer plate 20 abuts against the edge of the sealing plate 17. The thickness of the outer plate 20 is the same as the thickness of the sealing plate 17, enabling the resisting plate 15 to smoothly slide from the sealing plate 17 to the outer plate 20. A chute is formed between the outer plate 20 and the inner plate 5. Both ends of the resisting plate 15 extend into the chute. The resisting plate 15 is in sliding fit with the outer plate 20. A pressing block 21 is further arranged in the chute. The pressing block 21 is fixed on the inner plate 5 through an elastic piece 22. The pressing block 21 abuts against the resisting plate 15, and the edge of the resisting plate 15 is pressed against the outer plate 20 by the pressing block 21 to increase the sealing performance at the edge of the resisting plate 15 and the sealing plate 17.
