Description

Technical Field

[0001] This invention relates to the field of polyester production, specifically to a uniform humidification and setting device for polyester staple fiber production. Background Technology

[0002] Polyester staple fiber, a chemical short fiber material made of polyester, is widely used in textiles, clothing, and industrial manufacturing due to its high strength, wear resistance, and corrosion resistance. With the development of the industry, the requirements for the production quality and efficiency of polyester staple fiber are becoming increasingly stringent. Among them, the uniform humidification and setting process is crucial. During the stretching stage, if the ambient humidity is too low, the fiber will become brittle and easy to break. Proper humidification can improve the fiber's flexibility and reduce the risk of breakage.

[0003] Existing polyester staple fibers lack proper pre-humidification treatment before humidification, resulting in poor humidification during subsequent humidification processes. Furthermore, the humidified water cannot be effectively recycled, leading to water waste and failing to meet actual usage requirements.

[0004] Therefore, there is a need to provide a uniform humidification and setting device for polyester staple fiber production, which aims to solve the above problems. Summary of the Invention

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0034] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0035] See Figures 1-9 A uniform humidification and setting device for polyester staple fiber production includes a humidification chamber 1, on which a conveying roller 3 for conveying and driving polyester raw material 6 is provided. The conveying roller 3 is rotatably mounted on the outside of the humidification chamber 1 via a support frame 4. The device also includes:

[0036] The pre-humidification mechanism is installed on the humidification box 1 and is used to pre-humidify and uniformly humidify the incoming polyester raw material 6. The pre-humidification mechanism includes a first liquid inlet tank 26 for pre-humidification, a pre-humidification nozzle 55, a second liquid inlet tank 38 for uniform humidification, and a spray box 43. The first liquid inlet tank 26 is driven for pre-humidification by the transmission of the conveying roller 3, and the second liquid inlet tank 38 is driven for humidification and water supply by the drive of the first liquid inlet tank 26. A first toothed plate 31 and a second toothed plate 34 for accelerating the lifting of water supply are provided at the connection between the first liquid inlet tank 26 and the second liquid inlet tank 38. A first gear 32 is meshed with one side of the first toothed plate 31, and a second gear 33 is meshed with one side of the second toothed plate 34. The first gear 32 and the second gear 33 are meshed with each other, and the diameter of the first gear 32 is larger than that of the second gear 33.

[0037] Furthermore, the pre-humidification mechanism also includes a first piston plate 25 and a second water pipe 29 for water supply connection. The second water pipe 29 is connected to the pre-humidification nozzle 55 and the first infusion tank 26 respectively. A first transmission roller 7 is provided below the pre-humidification nozzle 55, and the polyester raw material 6 is driven and connected to the first transmission roller 7. The first infusion tank 26 is also connected to the interior of the water storage tank 2 through the first water pipe 27. A second one-way valve 30 is provided on the second water pipe 29, and a first one-way valve 28 is provided on the first water pipe 27. The first piston plate 25 is slidably connected to the interior of the first infusion tank 26 through the first piston rod 24.

[0038] Furthermore, the pre-humidification mechanism also includes a lifting frame 21 and an incomplete gear 20 for driving the first piston plate 25 to reciprocate. The incomplete gear 20 is rotatably connected to the humidification box 1 via a connecting shaft 19. The lifting frame 21 is provided with a number of teeth 22 that mesh with the incomplete gear 20. The lifting frame 21 is fixedly connected to the first piston rod 24 via the first lifting plate 23. The connecting shaft 19 is rotatably connected to the conveying roller 3 via a synchronous belt 18. The conveying roller 3 is fixedly connected to the output shaft of the motor 5. A first toothed plate 31 is fixedly connected to one side of the first lifting plate 23. The first toothed plate 31 is slidably connected to the inside of the protective shell 17. The protective shell 17 is installed on the outside of the humidification box 1.

[0039] Furthermore, the pre-humidification mechanism also includes a second piston plate 37 and a fourth water pipe 41 for water supply connection. The fourth water pipe 41 is connected to the second infusion tank 38 and the spray box 43 respectively. The second infusion tank 38 is also connected to the interior of the water storage tank 2 through a third water pipe 39. A fourth one-way valve 42 is provided on the fourth water pipe 41, and a third one-way valve 40 is provided on the third water pipe 39. The second piston plate 37 is slidably connected to the interior of the second infusion tank 38 through a second piston rod 36.

[0040] Furthermore, the pre-humidification mechanism also includes a second lifting plate 35 for driving the second piston plate 37 to reciprocate. The second piston plate 37 is fixedly connected to the second lifting plate 35 via the second piston rod 36. A second toothed plate 34 is fixedly connected to one side of the second lifting plate 35. The second toothed plate 34 is slidably connected to the inside of the protective shell 17.

[0041] Furthermore, the pre-humidification mechanism also includes a filter screen 45, an activated carbon layer 46, and an ion exchange layer 47 for purification. The filter screen 45, the activated carbon layer 46, and the ion exchange layer 47 are all installed inside the spray box 43. A pump body 44 is connected to the spray box 43 through a pipe. A humidification nozzle is provided at the connection between the pump body 44 and the interior of the humidification box 1.

[0042] Furthermore, a second transmission roller 10 for assisting the transmission of the polyester raw material 6 is also provided on one side of the second adjusting roller 9, and a filter plate 16 for filtration is provided at the bottom of the humidification box 1.

[0043] Preferably, during the humidification treatment of polyester raw material 6, the conveyor roller 3 drives and transports the material sequentially through the first drive roller 7, the first adjusting roller 8, the drive shaft 15, the second adjusting roller 9, and the second drive roller 10 to the lower pressure roller 11 and the upper pressure roller 12 for shaping. A traction roller (not shown in the figure) is correspondingly provided at the end of the polyester raw material 6 for traction transmission, facilitating the release of the conveyor roller 3. To improve subsequent humidification efficiency, while the polyester raw material 6 is being driven, the incomplete gear 20 on the connecting shaft 19 rotates under the synchronous drive of the synchronous belt 18. The incomplete gear 20 meshes with the teeth 22 in the lifting frame 21. Under the combined connection, the first piston plate 25 on the first piston rod 24 is driven to reciprocate inside the first infusion tank 26. Thus, under the one-way action of the second one-way valve 30 on the second water pipe 29 and the first one-way valve 28 on the first water pipe 27, the first infusion tank 26 draws water from the water storage tank 2 and injects it into the pre-humidification nozzle 55 through the second water pipe 29. This achieves the pre-humidification treatment of the polyester raw material 6 driven on the first drive roller 7. The purpose of this step is to allow the dry fiber to absorb a small amount of water first, reduce its surface resistance, and prepare for the subsequent deep and uniform humidification, preventing the phenomenon of "the surface is too wet, but the inside is still dry".

[0044] During the continued transmission of the polyester raw material 6, the first lifting plate 23 drives the first toothed plate 31 to move up and down reciprocally. With the first toothed plate 31, the first gear 32, the second gear 33, and the second toothed plate 34 meshing together, the second piston plate 37 on the second piston rod 36 is driven to move back and forth inside the second infusion tank 38 at a faster speed. Thus, under the one-way action of the fourth one-way valve 42 on the fourth water pipe 41 and the third one-way valve 40 on the third water pipe 39, the second infusion tank 38 is driven to draw water from the water storage tank 2 and inject it into the spray box 43 through the fourth water pipe 41. Since the water injected by the fourth water pipe 41 gradually rises from the bottom of the spray box 43, under the filtration and purification effect of the filter screen 45, the activated carbon layer 46, and the ion exchange layer 47, it is easier for the pump body 44 to draw cleaner water for spraying treatment, thereby improving the efficiency of uniform humidification and shaping of the polyester raw material 6.

[0045] The conveyor roller 3 in the device adopts a release-drive synchronous design, which enables the polyester raw material 6 to form a preliminary and uniform humidity base before entering the formal humidification stage. This effectively avoids the problem of excessive or insufficient local pre-humidification caused by unstable conveying of the polyester raw material 6, laying a solid foundation for subsequent deep and uniform humidification. At the same time, the supporting speed-up water supply structure provides efficient power support for the water pump to pump water and spray. While the water is purified, it can ensure stable operation of the spray, meeting the continuous humidification requirements of the polyester raw material 6 during the production process. In terms of quality, uniform humidification treatment enables the polyester raw material 6 to maintain a stable shrinkage rate during the subsequent setting process, avoiding problems such as uneven fiber thickness and poor elasticity after fiber setting caused by local humidity differences. This significantly improves the product consistency and mechanical properties of polyester staple fiber and reduces the product defect rate. In terms of efficiency, the synchronous drive of the conveyor roller 3 reduces the downtime for adjustment during the raw material conveying process. The synergistic effect of the two significantly improves the production efficiency of the entire humidification and setting process, effectively reducing the company's production costs and energy consumption, and further improving the stability and controllability of the production process.

[0046] like Figures 1 to 8 As shown, this embodiment, based on the above embodiment, also includes a tension adjustment mechanism, which is installed inside the humidification box 1 and is used to adjust the tension of the polyester raw material 6 being humidified. The tension adjustment mechanism includes a first adjustment roller 8 and a second adjustment roller 9 for tension adjustment drive. An adjustment rod 49 for tension drive is provided on the outer side of the first adjustment roller 8 and the second adjustment roller 9. The adjustment rod 49 is rotatably mounted on the humidification box 1 through a transmission shaft 15. The polyester raw material 6 is sequentially connected to the first adjustment roller 8, the transmission shaft 15 and the second adjustment roller 9.

[0047] The shaping mechanism is installed at the end of the humidification box 1 and is used to shape the humidified polyester raw material 6.

[0048] Furthermore, the tension adjustment mechanism also includes an electric push rod 54 for controlling the rotation of the adjustment rod 49. Both ends of the first adjustment roller 8 and the second adjustment roller 9 are slidably connected to the adjustment rod 49 by a slider 48. The adjustment rod 49 has a groove for avoiding the slider 48. A worm gear 50 is fixedly connected to the transmission shaft 15. A worm 51 is meshed on the worm gear 50. The worm 51 is rotatably installed inside the protective shell 17. A third gear 52 is fixedly connected to the worm 51. The third gear 52 is meshed on the third gear plate 53. The third gear plate 53 is fixedly connected to the piston rod of the electric push rod 54. The electric push rod 54 is fixedly installed inside the protective shell 17.

[0049] Furthermore, the shaping mechanism includes a lower pressure roller 11 and an upper pressure roller 12 for shaping connection. The lower pressure roller 11 is movably installed inside the humidification box 1, and the upper pressure roller 12 is movably installed on the pressure roller connecting frame 13. The pressure roller connecting frame 13 is fixedly connected to the piston rod of the lifting cylinder 14, and the lifting cylinder 14 is fixedly installed on the humidification box 1.

[0050] Preferably, in this embodiment, during the transmission of the polyester raw material 6, in order to further improve the humidification efficiency of the polyester raw material 6, corresponding tension adjustment is performed at the first adjusting roller 8 and the second transmission roller 10 connected to the transmission of the polyester raw material 6. Specifically, the piston rod of the electric push rod 54 drives the third toothed plate 53 to move, thereby driving the worm 51 to rotate under the meshing connection between the third toothed plate 53 and the third gear 52, and driving the adjusting rod 49 on the transmission shaft 15 to rotate under the meshing connection between the worm 51 and the worm wheel 50. The angle is rotated and driven. Since the two ends of the first adjusting roller 8 and the second adjusting roller 9 are slidably connected to the inside of the adjusting rod 49 through the slider 48, the first adjusting roller 8 and the second adjusting roller 9 can perform appropriate tension adjustment on the polyester raw material 6 when the adjusting rod 49 rotates, so that the polyester raw material 6 is in a more suitable straightened state for humidification treatment. The polyester raw material 6 reaches the lower pressure roller 11 and the upper pressure roller 12 through the transmission guide of the second transmission roller 10. The lifting cylinder 14 drives the upper pressure roller 12 to perform downward pressing and shaping treatment.

[0051] Both the lower pressure roller 11 and the upper pressure roller 12 are made of elastic material. Their pressure can be adjusted according to the fiber characteristics by the lifting cylinder 14 (pressure range 0.5-2MPa). For high-toughness fibers, the pressure will be appropriately reduced to avoid excessive stretching. For coarser fibers, the pressure will be appropriately increased to enhance the setting effect. During the pre-pressing and setting process, a heating device can be set inside the pressure roller, and the temperature can be controlled at 60-80℃. Gentle heating promotes the stable arrangement of fiber molecules, laying the foundation for subsequent complete setting.

[0052] On the one hand, when the polyester raw material 6 becomes slightly loose due to fluctuations in conveying speed or changes in its own humidity, the tension adjustment mechanism can apply pressure or make fine adjustments in position in real time to quickly restore the flat and relaxed state of the raw material and prevent the raw material from forming local stacking due to wrinkles. On the other hand, moderate tension promotes the deep penetration of the humidifying medium and avoids the "wet outside and dry inside" problem caused by fiber clumping in the traditional loose state, which further improves the overall humidity compliance rate of the raw material and lays the foundation for the stability of shrinkage rate in the subsequent setting process. This automated design of tension adjustment function also reduces manual intervention and avoids the operational errors caused by experience differences when manually adjusting tension in the traditional way, further improving the stability and controllability of the production process.

[0053] It should be noted that the components in this application are all general standard parts or components known to those skilled in the art, which effectively solve the technical problems raised in the background art.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
