[0018] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0019] Embodiment 1:

[0020] like Figure 1-Figure 5 As shown, the present invention discloses a ring-blowing cooling device for POY precursor, comprising a box body 1, a cooling pipe 2 is fixedly connected in the box body 1, the cooling pipe 2 runs through the box body 1, the POY precursor passes through the cooling pipe 2, an air inlet channel 4 is arranged on the box body 1, and the air inlet channel 4 is communicated with the inside of the box body 1; an air inlet mechanism is arranged in an array on the side wall of the cooling pipe 2, and the air inlet mechanism is as follows: a storage groove 5 is opened on the side wall of the cooling pipe 2, an elastic tube 6 is arranged through the storage groove 5, an annular airbag 7 is sleeved at both ends of the elastic tube 6 inside the cooling pipe 2, two piston cavities 8 are arranged in the cooling pipe 2 on the side of the corresponding storage groove 5, a piston column 9 is arranged in the piston cavity 8, the piston column 9 cooperates with the piston cavity 8, a corresponding driving groove 10 is arranged on the side of the piston cavity 8, the piston column 9 extends into the driving groove 10, a reciprocating mechanism is arranged in the driving groove 10, the reciprocating mechanism drives the piston column 9 to move, and the piston cavity 8 is communicated with the corresponding annular airbag 7 through a connecting pipe.

[0021] During normal spinning, the POY precursor passes through the cooling tube 2, and the cooling air enters the air inlet channel 4 on the box 1. The cooling air in the box 1 enters the cooling tube 2 from the elastic tube 6 under pressure. Since the elastic tube 6 is evenly arranged on the side wall of the cooling tube 2, the cooling air in the cooling tube 2 can enter more evenly. Annular airbags 7 are arranged in the storage grooves 5 at both ends of the elastic tube 6. The annular airbags 7 are sleeved on the elastic tube 6. Each annular airbag 7 corresponds to a piston cavity 8. A piston rod 9 is arranged in the piston cavity 8. The piston cavity 8 is connected to the annular airbag 7 through a pipeline. When the piston rod 9 moves, the air in the piston cavity 8 can be pressed into the annular airbag 7, so that the annular airbag 7 bulges, thereby compressing the elastic tube 6 to control the inner diameter of the elastic tube 6. The two annular airbags 7 cooperate to adjust the elastic tube 6 to form a reducer with different diameters at both ends, and adjust the wind speed entering the cooling tube 2 to adapt to the cooling of different POY precursors and ensure the stability of the precursor cooling process.

[0022] The structure of the reciprocating mechanism is as follows: a threaded rod 11 is rotatably arranged in the driving groove 10, the threaded rod 11 is parallel to the piston column 9, one end of the threaded rod 11 extends to the outside of the cooling pipe 2, a power mechanism is connected to the threaded rod 11 outside the cooling pipe 2, a connecting block 12 is threadedly connected to the threaded rod 11 in the driving groove 10, and the connecting block 12 is fixedly connected to the piston column 9. The power mechanism is used to drive the threaded rod 11 to rotate, and the connecting block 12 on the threaded rod 11 is threadedly connected to the threaded rod 11, and the connecting block 12 is fixedly connected to the piston column 9, so the connecting block 12 cannot rotate. When the threaded rod 11 rotates, the connecting block 12 can only move axially on the threaded rod 11, thereby driving the piston column 9 to reciprocate. Through this form of control, the structure is compact, and the control is simple and efficient.

[0023] The inner wall and outer wall of the cooling tube 2 at both ends of the storage tank 5 are concave to form a storage tank 14, which is connected to the storage tank 5.

An air head 15 is arranged in the storage tank 14, and the air head 15 is docked with the other end of the hose 16. A rotating rod 17 is arranged in the storage tank 14, and the rotating rod 17 is fixedly connected with the air head 15. The axial direction of the rotating rod 17 is perpendicular to the axial direction of the elastic tube 6, and the end of the rotating rod 17 is connected to the power mechanism. The air head 15 is a guide cylinder for air flow, which is an annular structure and is used to change the direction of input and output of air flow. The end of the air head 15 is connected to the elastic tube 6 through the hose 16 to ensure that the air head 15 can be docked with the elastic tube 6 during the rotation process, and the air flow delivery is more stable. The air head 15 is fixed by the rotating rod 17, so when the rotating rod 17 rotates, the angle of the air head 15 can be adjusted to change the angle of air intake and air outlet.

[0024] A fixed box 18 is arranged in the cooling pipe 2 on the side of the storage tank 14, one end of the rotating rod 17 extends into the fixed box 18, a turbine 19 is arranged on the rotating rod 17 in the fixed box 18, a worm 20 is rotatably arranged in the fixed box 18, and the worm 20 is cooperatively connected with the turbine 19, a transmission groove 21 is arranged in the cooling pipe 2 above the fixed box 18, the end of the worm 20 extends into the transmission groove 21, a bevel gear 23 is arranged on the worm 20 in the transmission groove 21, a transmission rod 22 is rotatably arranged in the transmission groove 21, a bevel gear 23 is arranged on the transmission rod 22 in the transmission groove 21, the bevel gear 23 on the transmission rod 22 is cooperatively connected with the bevel gear 23 on the worm 20, one end of the transmission rod 22 extends to the outside of the cooling pipe 2, and the transmission rod 22 outside the cooling pipe 2 is transmission-connected with the power mechanism. Since the rotating rod 17 is perpendicular to the axial direction of the elastic tube 6, the worm 20 and the transmission rod 22 in the fixed box 18 are used to extend its power input end to the outside of the cooling tube 2. The transmission rod 22 is transmitted to the worm 20 through the bevel gear 23, and the worm 20 cooperates with the turbine 19 at the end of the rotating rod 17 to realize transmission. At the same time, it has self-locking ability and can be stably maintained after the angle of the air head 15 is adjusted.

The elastic tubes 6 on the cooling tube 2 are arranged at intervals along the axial direction. In this way, a first electric telescopic rod 27 is used to drive the lifting and lowering of the second electric telescopic rod 30, and the rectangular blocks 33 of the four servo motors 32 on the moving block 31 can always cooperate with the rectangular grooves 34 on the corresponding drive button 13 to rotate the drive button 13. The servo motor 32 drives the drive button 13 to rotate, thereby adjusting the rotating rod 17 and the transmission rod 22. This adjustment has strong versatility.

[0027] A guide plate 3 is arranged in the box body 1, and the guide plate 3 divides the box body 1 into two independent cavities, the upper and lower cavities.
