Description

Technical Field

[0001] The invention relates to the technical field of polyester production, in particular to polyester yarn production and drying equipment. Background Art

[0002] Polyester is an important type of synthetic fiber and is the trade name for polyester fiber in my country. It is a fiber-forming polymer made from purified terephthalic acid or dimethyl terephthalate and ethylene glycol through esterification or ester exchange and polycondensation reactions, namely polyethylene terephthalate. The fiber is made through spinning and post-processing. The characteristics of polyester silk are that it can withstand chemicals and frequent washing, reducing fading and discoloration of clothing. Therefore, hotel uniforms, stone-ground blue denim clothing, sportswear or children's clothing are all made of polyester yarn. Relatively speaking, polyester yarn is tougher than rayon. When embroidery is carried out, the machine runs at high speed, and the high-toughness polyester thread can also withstand greater tension. It is also highly fire-resistant and is not easily ignited even if the clothing is close to the flame.

[0003] At present, when making polyester yarn, the raw materials are first subjected to the melt spinning process, which means that the polyester raw materials are subjected to certain processing, and then enter the screw extruder for heating after pelletizing, wet slicing and other processes to form yarns. The formed polyester yarn needs to be sprayed with water or cooled by water so that the polyester yarn can be quickly shaped. After cooling, the wet polyester yarn needs to be dried. In the existing technology, when drying polyester yarn, the polyester yarn is first extruded to squeeze the moisture in the center to its outer surface, and then before the final winding, the polyester yarn is quickly passed through a drying box for a drying process. However, during drying, since the polyester yarn is composed of multiple groups of filaments, and the polyester yarn is always densely squeezed together, it is easy to cause the filaments in the middle part to be not dried thoroughly, which in turn affects the subsequent processing after winding. For this reason, we propose a polyester yarn production drying equipment. Summary of the Invention

The outer surfaces of the first rubbing roller 14 and the second rubbing roller 15 have certain friction properties, and the first rubbing roller 14 is rotatably connected to the first fixed shaft 16 fixedly connected to the inner wall of the drying box 5; the power assembly 17 is arranged on the support frame 4 and is located below the drying box 5, and the power assembly 17 is connected to the extrusion assembly 7 and the rubbing assembly 13. In order to improve the drying efficiency of the polyester yarn, the feed end of the support frame 4 is provided with a drying box 47 fixedly connected to the drying box 5, and a desiccant is provided in the drying box 47;

[0028] When the polyester strip 49 needs to be dried, it will first pass through the feed rack 3, the squeezing rack 1 and the drying box 5 in sequence. When passing through the squeezing rack 1, the polyester strip 49 will pass between multiple groups of first squeezing rollers 10 and second squeezing rollers 11, and in the drying box 5, the polyester strip 49 will pass between the first rubbing roller 14 and the second rubbing roller 15. During this process, the polyester strip 49 enters from the feed rack 3 and is wound at the discharge end of the drying box 5. Through the operation of the power component 17, the squeezing component 7 and the rubbing component 13 are driven to operate at the same time, which solves the problem that when drying, the polyester yarn is composed of multiple groups of filaments, and the polyester yarns are always densely squeezed together, which easily leads to incomplete drying of the filaments in the middle part, and thus affects the subsequent processing after winding.

[0029] The extrusion assembly 7 includes two groups of sliding seats 18 respectively arranged in the sliding groove 2, the sliding seat 18 is slidably connected to the inner wall of the squeezing frame 1 through the sliding groove 2, and the two groups of sliding seats 18 are respectively rotatably connected to the two ends of the multiple groups of second rotating shafts 12, a lifting block 19 is fixedly connected to the sliding seat 18, and a lifting rod 20 with one end fixedly connected thereto is provided at the bottom end of the lifting block 19, the lifting rod 20 is slidably connected to a bending tube 21, and the outer side of the bending tube 21 is fixedly connected to a fixed block 22 fixedly connected to the support frame 4, and the two groups of bending tubes 21 are fixedly connected to a docking tube 23 at one end away from the lifting rod 20.

[0030] The power assembly 17 operates to push the rubber sleeve 48, and drives the moving block 35 to move through the rubber sleeve 48. The moving block 35 then cooperates to move back and forth in the moving groove 6. Since there is a small distance between the rubber sleeve 48 and the two groups of blocking blocks 42, the frequency of the reciprocating movement of the moving block 35 is low. The moving block 35 also drives the driving rod 34 to move, and the driving rod 34 then drives the two groups of driving blocks to move. The two groups of driving blocks 32 cooperate to drive the sliding sleeve 29 to move on the second fixed shaft 28, and continuously squeeze the second spring 31 through the resistance blocks 30 at both ends. While the sliding sleeve 29 drives the second rubbing shaft to rotate, it also drives the second rubbing shaft to continuously reciprocate and cooperate with the fixed first rubbing shaft to slightly rub the polyester strip 49, so that the middle part of the polyester strip 49 is fully dried in the drying box 5.

[0031] The rubbing assembly 13 includes a second fixed shaft 28 arranged just below the first fixed shaft 16, a sliding sleeve 29 is sleeved on the outer side of the second fixed shaft 28 and fixedly connected to the second rubbing roller 15, and both ends of the sliding sleeve 29 are fixedly connected to interference blocks 30, and both ends of the second fixed shaft 28 are sleeved with second springs 31, and the springs are located between the inner wall of the drying box 5 and the interference blocks 30. Both ends of the second rubbing roller 15 are provided with driving blocks 32 with one end rotatably connected to the sliding sleeve 29, and a swinging mechanism 33 adapted to the moving groove 6 is provided between the bottom ends of the two groups of driving blocks 32. The swinging mechanism 33 includes a driving rod 34 arranged in the drying box 5 and fixedly connected to the bottom ends of the two groups of driving blocks 32, and a moving block 35 with one end fixedly connected thereto is provided on the driving rod 34. The moving block 35 passes through the moving groove 6, and the bottom end of the moving block 35 is located outside the drying box 5;

[0032] When the power assembly 17 is in operation, the connecting pipe 23 is connected to the bending pipe 21, thereby extracting the air in the bending pipe 21. At this time, the lifting rod 20 is pulled downward through the vent hole 27 on the connecting block 26, and the first spring 25 is squeezed and contracted. When the lifting rod 20 moves downward, the sliding seat 18 is driven downward through the lifting block 19. The sliding seat 18 slides downward in the sliding groove 2 at this time. The sliding seat 18 drives the multiple sets of second rotating shafts 12 and the second squeezing rollers 11 to move downward at the same time. At this time, the second squeezing rollers 11 cooperates with the first squeezing roller 10 to squeeze the polyester strip 49, and when the piston block 41 moves into the air storage cylinder 40, the air is pushed into the bending tube 21 again, and finally cooperates with the rebound first spring 25 to move the second squeezing roller 11 upward. The second squeezing roller 11 continuously squeezes the polyester strip 49 onto the first squeezing roller 10 during the continuous lifting process, thereby squeezing water out of the polyester strip 49 and achieving a certain kneading effect, thereby improving the treatment of moisture in the middle part of the polyester strip 49.

[0033] The power assembly 17 includes a storage rack 36 arranged below the drying box 5 and fixedly connected to the support frame 4. An electric telescopic rod 37 is installed on the storage rack 36. The output end of the electric telescopic rod 37 is provided with a mounting block 38 fixedly connected to it at one end. The other end of the mounting block 38 is fixedly connected to a piston rod 39. The outer side of the piston rod 39 is provided with an air storage cylinder 40 fixedly connected to the storage rack 36. The air storage cylinder 40 is provided with a piston block 41 fixedly connected to the piston rod 39. The piston rod 39 is slidably connected to the bottom end of the moving block 35. Both sides of the moving block 35 are provided with a blocking block 42 fixedly connected to the piston rod 39. The end of the air storage cylinder 40 away from the blocking block 42 is provided with A communication mechanism 43 connected to the docking tube 23 includes a communication block 44 disposed on the air reservoir 40 and away from one end of the stop block 42. The communication block 44 is provided with a connecting tube 45 at one end thereof, the other end of the connecting tube 45 being in communication with the interior of the docking tube 23. A lifting block 46 fixedly connected to the storage rack 36 is fixedly connected to the outer side of the connecting tube 45. In addition, to protect the moving block 35 and the stop block 42 during operation, a rubber sleeve 48 sleeved on the piston rod 39 is fixedly connected to the bottom end of the moving block 35. The rubber sleeve 48 is located between the two sets of stop blocks 42, but there is a small distance between the rubber sleeve 48 and the two sets of stop blocks 42.

[0034] The electric telescopic rod 37 on the storage rack 36 operates to make it continuously reciprocate and retract. The output end of the electric telescopic rod 37 drives the mounting block 38 to move back and forth. The mounting block 38 drives the piston rod 39 to move continuously, thereby driving the piston block 41 to slide back and forth continuously in the air storage cylinder 40. During this process, the air in the air storage cylinder 40 is continuously extracted and released. When the piston block 41 moves toward the outside of the air storage cylinder 40, the air in the connecting pipe 45 is extracted through the air storage cylinder 40 and the connecting block 44, thereby driving the extrusion assembly 7 to operate. During the reciprocating movement of the piston rod 39, the blocking block 42 on the piston rod 39 moves simultaneously. When the blocking block 42 contacts the rubber sleeve 48, the rubber sleeve 48 is pushed, and the moving block 35 is driven to move through the rubber sleeve 48. The rubbing assembly 13 also operates at this time.

[0035] When the polyester strip 49 needs to be dried, it will first pass through the feed rack 3, the squeeze rack 1 and the drying box 5 in sequence. When passing through the squeeze rack 1, the polyester strip 49 will pass between the multiple sets of first squeezing rollers 10 and second squeezing rollers 11. In the drying box 5, the polyester strip 49 will pass between the first rubbing roller 14 and the second rubbing roller 15. During this process, the polyester strip 49 enters the feed rack 3 and is wound at the discharge end of the drying box 5. When drying, the electric telescopic rod 37 on the storage rack 36 is first controlled to operate. , so that it can continue to reciprocate and extend, the output end of the electric telescopic rod 37 drives the mounting block 38 to move back and forth, and the mounting block 38 drives the piston rod 39 to move continuously, thereby driving the piston block 41 to slide back and forth continuously in the air storage cylinder 40. During this process, the air in the air storage cylinder 40 is continuously extracted and released. When the piston block 41 moves to the outside of the air storage cylinder 40, the air in the connecting pipe 45 is extracted through the air storage cylinder 40 and the connecting block 44. The connecting pipe 45 is connected to the docking pipe 23, and the docking pipe 2 3 is connected to the bending tube 21, and the air in the bending tube 21 is extracted. At this time, the lifting rod 20 is pulled downward through the vent hole 27 on the connecting block 26, and the first spring 25 is squeezed and contracted. When the lifting rod 20 moves downward, the lifting block 19 drives the sliding seat 18 downward. The sliding seat 18 slides downward in the sliding groove 2 at this time, and the sliding seat 18 drives multiple sets of second rotating shafts 12 and second squeezing rollers 11 to move downward at the same time. At this time, the second squeezing rollers 11 and the first squeezing rollers 1 0 cooperates to squeeze the polyester strip 49, and when the piston block 41 moves into the interior of the air storage cylinder 40, the air is pushed into the bending tube 21 again, and finally cooperates with the rebounding first spring 25 to move the second squeezing roller 11 upward. During the continuous lifting process, the second squeezing roller 11 continuously squeezes the polyester strip 49 onto the first squeezing roller 10, thereby squeezing water out of the polyester strip 49 and achieving a certain kneading effect, thereby improving the treatment of moisture in the middle part of the polyester strip 49;

[0036] When the piston rod 39 is in the reciprocating movement process, the blocking block 42 on the piston rod 39 moves simultaneously. When the blocking block 42 contacts the rubber sleeve 48, the rubber sleeve 48 is pushed, and the moving block 35 is driven to move by the rubber sleeve 48. The moving block 35 is then matched to move back and forth in the moving groove 6. Since there is a small distance between the rubber sleeve 48 and the two groups of blocking blocks 42, the frequency of the reciprocating movement of the moving block 35 is low. The moving block 35 simultaneously drives the driving rod 34 to move, and the driving rod 34 then drives the two groups of driving blocks to move. The two sets of driving blocks 32 cooperate to drive the sliding sleeve 29 to move on the second fixed shaft 28, and continuously squeeze the second spring 31 through the resistance blocks 30 at both ends. While the sliding sleeve 29 drives the second rubbing shaft to rotate, it also drives the second rubbing shaft to move back and forth continuously, cooperating with the fixed first rubbing shaft to slightly rub the polyester strip 49, so that the middle part of the polyester strip 49 is fully dried in the drying box 5, and the overall cooperation improves the drying of the polyester strip 49, which is convenient for the subsequent processing of the polyester strip 49.
