Description

Technical Field

[0001] This invention relates to the field of raw yarn processing equipment, and in particular to a ring-blowing cooling device for POY raw yarn. Background Technology

[0002] POY precursor yarn refers to pre-oriented yarn. Pre-oriented yarn is an incompletely stretched chemical fiber filament obtained through high-speed spinning, with an orientation degree between that of unoriented and drawn yarn. With the continuous improvement of spinning technology and the development and application of corresponding equipment, chemical fiber spinning cooling equipment has been replaced by ring-blown cooling equipment instead of traditional side-blown cooling equipment. However, the air guides in existing ring-blown cooling equipment are all fixed and cannot be adjusted as needed, resulting in uneven cooling of the POY precursor yarn. Summary of the Invention

[0003] To address the shortcomings of the aforementioned technology, this invention provides a ring-blowing cooling device for POY precursor yarn, which can adjust the opening size of the air guide to accommodate the production of different POY precursor yarns.

[0004] This invention discloses a ring-blowing cooling device for POY precursor yarn, comprising a housing, a cooling pipe fixedly connected inside the housing, the cooling pipe penetrating the housing, and the POY precursor yarn passing through the cooling pipe. An air inlet channel is provided on the housing, communicating with the interior of the housing. Air intake mechanisms are arranged in a spaced array on the side wall of the cooling pipe. Each air intake mechanism consists of a storage slot on the side wall of the cooling pipe, a flexible tube penetrating within the storage slot, and annular airbags sleeved at both ends of the flexible tube inside the cooling pipe. Two piston chambers are provided in the cooling pipe on the side of the corresponding storage slot, and piston columns are provided in the piston chambers, cooperating with the piston chambers. Corresponding drive slots are provided on the side of the piston chambers, and the piston columns extend into the drive slots. A reciprocating mechanism is provided in the drive slots, driving the piston columns to move. The piston chambers and corresponding annular airbags are connected by connecting pipes.

[0005] The reciprocating mechanism has the following structure: a threaded rod is rotatably arranged in the drive groove, the threaded rod is parallel to the piston column, one end of the threaded rod extends to the outside of the cooling pipe, a power mechanism is connected to the threaded rod outside the cooling pipe, and a connecting block is threadedly connected to the threaded rod in the drive groove, the connecting block is fixedly connected to the piston column.

[0006] Storage troughs are formed by recesses on the inner and outer walls of the cooling pipes at both ends of the storage trough. The storage troughs are connected to the storage trough. A flexible hose is installed in the storage trough near one end of the storage trough. One end of the flexible hose is connected to the elastic tube. An air head is installed in the storage trough and is connected to the other end of the flexible hose. A rotating rod is installed in the storage trough and is fixedly connected to the air head. The axis of the rotating rod is perpendicular to the axis of the elastic tube. The end of the rotating rod is connected to the power mechanism for transmission.

[0007] A fixed box is installed inside the cooling pipe on the side of the storage tank. One end of the rotating rod extends into the fixed box. A turbine is installed on the rotating rod inside the fixed box. A worm gear is rotatably installed inside the fixed box. The worm gear and the turbine are connected. A transmission groove is installed inside the cooling pipe above the fixed box. The end of the worm gear extends into the transmission groove. A bevel gear is installed on the worm gear inside the transmission groove. A transmission rod is rotatably installed inside the transmission groove. A bevel gear is installed on the transmission rod inside the transmission groove. The bevel gear on the transmission rod is connected to the bevel gear on the worm gear. One end of the transmission rod extends to the outside of the cooling pipe. The transmission rod outside the cooling pipe is connected to the power mechanism.

[0008] A drive button is provided at the ends of the two threaded rods and two transmission rods outside the cooling pipe. A recessed rectangular groove is provided on the outer wall of the drive button. A receiving cavity is provided on the inner wall of the top of the box outside the cooling pipe. A first electric telescopic rod is provided on the box, and the end of the first electric telescopic rod extends into the receiving cavity. The end of the first electric telescopic rod and the receiving cavity are slidably connected by a sealing ring. A second electric telescopic rod is provided at the end of the first electric telescopic rod inside the receiving cavity. The telescopic end of the second electric telescopic rod faces the outer wall of the cooling pipe. A moving block is provided at the telescopic end of the second electric telescopic rod. Four servo motors are provided on the moving block. A rectangular block that mates with the rectangular groove is provided on the output end of the servo motor. Each rectangular block corresponds to a drive button.

[0009] A baffle plate is installed inside the housing, dividing the housing into upper and lower independent cavities. The cooling pipe passes through the baffle plate. The air inlet mechanism is installed on the cooling pipe above the baffle plate, and the air inlet pipe is installed on the housing below the baffle plate. Several annular inlet slots are evenly spaced on the baffle plate. An annular cavity with a V-shaped cross-section is installed in the baffle plate at the corresponding position of the inlet slot. The bottom of the inlet slot is connected to the bottom of the annular cavity. The upper two sides of the annular cavity are provided with discharge holes. The discharge holes are arranged in a ring and are connected to the upper two sides of the annular cavity.

[0010] The POY precursor cooling device obtained by this invention has the following beneficial effects:

[0011] By using the flexible tube and annular airbag, the diameter of both ends of the flexible tube can be adjusted. At the same time, by adjusting the air head angle at both ends of the flexible tube, the speed and flow rate of the cold air entering the cooling pipe can be changed, resulting in more uniform cooling distribution and minimizing the shaking of the filament path, thus reducing the probability of fuzz formation.

[0012] The design of the guide plate and the V-shaped annular cavity, inlet groove and outlet hole on the guide plate allows the airflow to enter the outer box of the cooling pipe more evenly, so that the process of airflow entering the cooling pipe is more uniform and stable, and the cooling effect on POY filament is more uniform.

[0018] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0019] Example 1:

[0020] like Figures 1-5 As shown, this invention discloses a ring-blowing cooling device for POY precursor yarn, including a housing 1. A cooling pipe 2 is fixedly connected inside the housing 1, and the cooling pipe 2 penetrates the housing 1. The POY precursor yarn passes through the cooling pipe 2. An air inlet channel 4 is provided on the housing 1, and the air inlet channel 4 communicates with the interior of the housing 1. An air inlet mechanism is arranged at intervals on the side wall of the cooling pipe 2. The air inlet mechanism is as follows: a storage groove 5 is opened on the side wall of the cooling pipe 2, and an elastic tube 6 is provided through the storage groove 5. Annular air bags 7 are sleeved at both ends of the elastic tube 6 inside the cooling pipe 2. Two piston chambers 8 are provided in the cooling pipe 2 on the side of the corresponding storage groove 5. A piston column 9 is provided in the piston chamber 8, and the piston column 9 cooperates with the piston chamber 8. A corresponding drive groove 10 is provided on the side of the piston chamber 8, and the piston column 9 extends into the drive groove 10. A reciprocating mechanism is provided in the drive groove 10, and the reciprocating mechanism drives the piston column 9 to move. The piston chamber 8 and the corresponding annular air bag 7 are connected by a connecting pipe.

[0021] During normal spinning, the POY precursor yarn passes through the cooling pipe 2, and cooling air enters through the air inlet channel 4 on the housing 1. Under pressure, the cooling air inside the housing 1 enters the cooling pipe 2 through the elastic tube 6. Since the elastic tubes 6 are evenly spaced on the side wall of the cooling pipe 2, the entry of cooling air into the cooling pipe 2 is relatively uniform. Annular airbags 7 are installed in the storage slots 5 at both ends of the elastic tube 6. Each annular airbag 7 corresponds to a piston chamber 8, and a piston column 9 is installed in the piston chamber 8. The piston chamber 8 and the annular airbag 7 are connected by a pipe. When the piston column 9 moves, it can force the air in the piston chamber 8 into the annular airbag 7, causing the annular airbag 7 to inflate, thereby compressing the elastic tube 6 to control its inner diameter. The two annular airbags 7 work together to adjust the elastic tube 6, forming a variable diameter tube with different diameters at both ends, thus adjusting the airflow speed entering the cooling pipe 2 to adapt to the cooling of different POY precursor yarns and ensure stability during the yarn cooling process.

[0022] The reciprocating mechanism has the following structure: a threaded rod 11 is rotatably mounted within the drive groove 10, parallel to the piston rod 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 within the drive groove 10, and the connecting block 12 is fixedly connected to the piston rod 9. The power mechanism drives the threaded rod 11 to rotate, while the connecting block 12 is threadedly connected to the threaded rod 11 and fixedly connected to the piston rod 9. Therefore, the connecting block 12 cannot rotate. When the threaded rod 11 rotates, the connecting block 12 can only move axially along the threaded rod 11, thereby driving the piston rod 9 to reciprocate. This control method results in a compact structure and simple, efficient control.

[0023] Storage grooves 14 are formed by recesses on the inner and outer walls of the cooling pipes 2 at both ends of the storage groove 5. Storage grooves 14 are connected to the storage groove 5. A flexible hose 16 is installed in the storage groove 14 near one end of the storage groove 5. One end of the flexible hose 16 is connected to the elastic tube 6. An air head 15 is installed in the storage groove 14, and the other end of the air head 15 is connected to the flexible hose 16. A rotating rod 17 is installed in the storage groove 14, and the rotating rod 17 is fixedly connected to the air head 15. The axis of the rotating rod 17 is perpendicular to the axis of the elastic tube 6, and the end of the rotating rod 17 is connected to a power mechanism. The air head 15 is an airflow guide cylinder with an annular structure, used to change the direction of airflow input and output. The end of the air head 15 is connected to the elastic tube 6 via the flexible hose 16 to ensure that it remains connected to the elastic tube 6 during rotation, resulting in more stable airflow delivery. The air head 15 is fixed by the rotating rod 17, so rotating the rod 17 adjusts the angle of the air head 15, changing the angle of air intake and exhaust.

[0024] A fixed box 18 is provided inside 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 provided on the rotating rod 17 inside the fixed box 18. A worm gear 20 is rotatably provided inside the fixed box 18. The worm gear 20 is connected to the turbine 19. A transmission groove 21 is provided inside the cooling pipe 2 above the fixed box 18. The end of the worm gear 20 extends into the transmission groove 21. A bevel gear 23 is provided on the worm gear 20 inside the transmission groove 21. A transmission rod 22 is rotatably provided inside the transmission groove 21. A bevel gear 23 is provided on the transmission rod 22 inside the transmission groove 21. The bevel gear 23 on the transmission rod 22 is connected to the bevel gear 23 on the worm gear 20. One end of the transmission rod 22 extends to the outside of the cooling pipe 2. The transmission rod 22 outside the cooling pipe 2 is connected to the power mechanism. Since the rotating rod 17 is perpendicular to the axis of the elastic tube 6, the worm gear 20 and 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 transmits power to the worm gear 20 through the bevel gear 23, and the worm gear 20 cooperates with the turbine 19 at the end of the rotating rod 17 to realize transmission. At the same time, it has a self-locking ability and can be stably maintained after the angle of the air head 15 is adjusted.

[0025] A drive button 13 is provided at the ends of the two threaded rods 11 and the two transmission rods 22 outside the cooling pipe 2. A recessed rectangular groove 34 is provided on the outer wall of the drive button 13. A receiving cavity 28 is provided on the inner wall of the top of the box 1 outside the cooling pipe 2. A first electric telescopic rod 27 is provided on the box 1. The end of the first electric telescopic rod 27 extends into the receiving cavity 28. The end of the first electric telescopic rod 27 and the receiving cavity 28 are slidably connected by a sealing ring 29. A second electric telescopic rod 30 is provided at the end of the first electric telescopic rod 27 in the receiving cavity 28. The telescopic end of the second electric telescopic rod 30 faces the outer wall of the cooling pipe 2. A moving block 31 is provided at the telescopic end of the second electric telescopic rod 30. Four servo motors 32 are provided on the moving block 31. A rectangular block 33 that cooperates with the rectangular groove 34 is provided on the output end of the servo motor 32. The rectangular block 33 corresponds one-to-one with the drive button 13.

[0026] To improve the rotation adjustment of the threaded rod 11 and the transmission rod 22, drive knobs 13 are installed at the ends of the threaded rod 11 and the transmission rod 22 corresponding to both ends of an elastic tube 6, and the four drive knobs 13 corresponding to each elastic tube 6 are arranged in the same manner. The elastic tubes 6 on the cooling pipe 2 are arranged at intervals along the axial direction. In this way, a first electric telescopic rod 27 drives the raising 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 slots 34 on the corresponding drive knobs 13 to rotate the drive knobs 13. The servo motors 32 drive the drive knobs 13 to rotate, thereby adjusting the rotating rod 17 and the transmission rod 22. This adjustment method has strong versatility.

[0027] A guide plate 3 is provided inside the housing 1, which divides the housing 1 into two independent cavities, upper and lower. The cooling pipe 2 passes through the guide plate 3. The air inlet mechanism is located on the cooling pipe 2 above the guide plate 3, and the air inlet pipe is located on the housing 1 below the guide plate 3. Several annular inlet grooves 24 are evenly arranged on the guide plate 3. An annular cavity 25 with a V-shaped cross section is provided in the guide plate 3 at the corresponding position of the inlet groove 24. The bottom of the inlet groove 24 is connected to the bottom of the annular cavity 25. The upper two sides of the annular cavity 25 are provided with discharge holes 26. The discharge holes 26 are arranged in a ring and are connected to the upper two sides of the annular cavity 25.

[0028] Because an air inlet duct is installed on the housing 1, a guide plate 3 is installed inside the housing 1 below the air inlet mechanism to maintain stable air pressure around the cooling pipe 2. The air inlet duct delivers airflow to the housing 1 below the guide plate 3, and then evenly discharges it upwards into the housing 1 above the guide plate 3 through the inlet groove 24, annular cavity 25, and outlet hole 26 on the guide plate 3, thus keeping the air pressure around the air inlet mechanism stable. The inlet groove 24 and annular cavity 25 allow for more uniform airflow guidance.
