Description

Technical Field

[0001] The present application relates to the technical field of textile machinery and equipment, and in particular to a drying device for polyester staple fibers. Background Art

[0002] In the modern textile industry, polyester is widely used in the manufacture of various textiles due to its excellent properties. Polyester staple fiber production lines typically include multiple processes, including spinning, drawing, and crimping. Drying, among other steps, is crucial for improving fiber quality by removing any solvents or other liquid components from the freshly spun polyester staple fibers.

[0003] Currently, most polyester staple fiber drying devices used in the market use hot air circulation drying. However, in actual use, this traditional drying equipment is prone to increased stickiness on the fiber surface due to sudden high temperatures or low humidity inside the drying equipment. This makes it difficult to avoid the risk of fiber self-adhesion caused by high temperatures. This is especially true when the polyester fiber is conveyed at a slow speed or the fiber bulk density is high. This not only affects the drying efficiency of the drying equipment, but also the quality of the final polyester staple fiber product. Utility Model Content

[0004] In order to reduce the possibility of adhesion of polyester yarn bundles during transportation, the present application provides a drying device for polyester staple fibers.

[0005] The present application provides a drying device for polyester staple fibers using the following technical solutions:

[0006] A drying device for polyester staple fiber, comprising a drying box, wherein the ends of the drying box along its own length direction are respectively provided with a feed port and a discharge port, a plurality of guide rods are distributed in the drying box along the conveying direction of the polyester fiber, and the polyester fiber passes through the plurality of guide rods in sequence during the conveying process, a hot air blower is provided on the top of the drying box, an air distribution plate is provided on the inner top of the drying box, a warm air cavity is provided inside the air distribution plate, a plurality of air outlet holes connected to the warm air cavity are provided on the bottom wall of the air distribution plate, the air outlet of the hot air blower is connected to the warm air cavity, and a thermometer plugged into the warm air cavity is also provided on the air distribution plate, a controller is provided on the outer wall of the drying box, and the thermometer and the hot air blower are electrically connected to the controller.

[0007] By adopting the above technical solution, the drying device for polyester staple fiber can evenly distribute hot air along the length of the drying box, ensuring that the polyester fiber is fully dried during the transportation process. At the same time, the temperature control system can effectively avoid fiber adhesion caused by high temperature, thereby improving the drying efficiency and product quality of polyester staple fiber.

[0008] Optionally, each of the air distribution plates is arranged in an arc shape, the arc center of the air distribution plate is located below itself, and the center line of the arc center of the air distribution plate is arranged parallel to the conveying direction of the polyester fiber, and the distance between the two sides of the air distribution plate parallel to its own length direction exceeds the length dimension of the feed port.

[0009] By adopting this technical solution, the curved design of the air distribution plate not only effectively guides the warm air generated by the hot air blower to evenly cover the polyester fibers, preventing uneven drying, but also guides the moisture rising from the polyester fibers through the curved plate of the air distribution plate to the bottom of the drying chamber. This not only improves the drying efficiency of the drying device, but also prevents moisture from re-entering the polyester fibers.

[0010] Optionally, each guide rod is provided with a rotating sleeve, and the rotating sleeve is rotatably engaged with the corresponding guide rod, and a plurality of comb teeth are distributed on the outer peripheral wall of each rotating sleeve.

[0011] By adopting the above technical solution, the polyester fibers can be evenly distributed during the transportation process and combed by multiple comb teeth, which effectively reduces the possibility of fiber adhesion due to accumulation during the drying process.

[0012] Optionally, the rotating sleeve mounted on the guide rod is slidably engaged with the guide rod, an elastic member is mounted on one end portion of the guide rod for abutting the rotating sleeve and the opposite side wall of the drying box, and a driving component is provided on the other end for driving the rotating sleeve to slide toward the elastic member.

[0013] By adopting the above technical solution, under the coordinated action of the driving assembly and the elastic member, the rotating sleeve can slide back and forth along the central axis of the guide rod, so that the comb teeth on the outer wall of the rotating sleeve can move back and forth. The comb teeth can move the polyester fibers back and forth during the transportation process, so that the polyester fibers are fully in contact with the hot air in the drying box, further improving the drying efficiency of the drying device.

[0014] Optionally, the driving assembly includes an eccentric wheel rotatably set on the guide rod and a driving motor that drives the eccentric wheel to rotate. The rotating shaft of the eccentric wheel is perpendicular to the length direction of the guide rod and is rotatably set on the end of the guide rod away from the elastic member, and the eccentric wheel is always set in contact with the side wall of the rotating sleeve during rotation.

[0015] By adopting the above technical solution, the eccentric wheel rotates under the drive of the drive motor and always contacts the side wall of the rotating sleeve, so that the rotating sleeve slides back and forth along the guide rod, thereby driving the comb teeth to comb the polyester fibers, effectively preventing the fibers from sticking during the drying process, thereby improving the working efficiency of the drying device and product quality.

[0016] Optionally, the rotating shafts of several eccentric wheels are arranged in parallel, and a synchronous wheel is sleeved on the rotating shaft of each eccentric wheel. A synchronous belt is meshed together on several synchronous wheels, and the rotation angles of two adjacent eccentric wheels are inconsistent.

[0017] By adopting the above technical solution, the meshing arrangement of the synchronous wheel and the synchronous belt enables several eccentric wheels to move synchronously. The synchronous movement of the eccentric wheels drives the rotating sleeve to slide evenly along the guide rod. In addition, the rotation angles of two adjacent eccentric wheels are inconsistent, so that the forward and backward movement positions of the two adjacent rotating sleeves are staggered along the water direction, thereby enhancing the degree of contact between the polyester fiber and the hot air in the drying box, and further improving the drying efficiency of the drying device.

[0018] Optionally, two parallel guide rollers are rotatably provided at the feed inlet of the drying box, and the guide rollers are rotatably provided on opposite side walls of the feed inlet along both sides of the polyester fiber conveying direction.

[0019] By adopting the above technical solution, the setting of the guide roller helps to distribute the polyester fibers more evenly when entering the drying box, reduces the degree of disorder of the fibers when entering the drying box, thereby effectively avoiding entanglement and adhesion of the fibers during the drying process, and improving the drying quality and efficiency.

[0020] Optionally, a humidity sensor is provided at the discharge port of the drying box.

[0021] By adopting the above technical solution, the humidity sensor installed at the discharge port of the drying box can monitor the humidity of the polyester staple fiber at the end of the drying process in real time, ensuring that the fiber drying degree meets the process requirements, thereby improving the quality of the final product.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. This polyester staple fiber drying device can evenly distribute hot air along the length of the drying chamber, ensuring that the polyester fibers are fully dried during transportation. At the same time, the temperature control system effectively prevents fiber adhesion caused by high temperatures, thereby improving drying efficiency and polyester staple fiber product quality.

[0024] 2. The curved design of the air distribution plate not only effectively guides the warm air generated by the hot air blower to evenly cover the polyester fibers, preventing uneven drying, but also guides the moisture rising from the polyester fibers through the curved plate of the air distribution plate to the bottom of the drying chamber. This not only improves the drying efficiency of the drying device, but also prevents moisture from re-entering the polyester fibers.

[0025] 3. The polyester fibers can be evenly distributed during the conveying process and combed by multiple comb teeth, which effectively reduces the possibility of fiber adhesion due to accumulation during the drying process. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The embodiment of the present application discloses a drying device for polyester staple fibers.

[0033] Reference Figures 1 to 3 A drying device for polyester staple fibers includes a drying box 1, a heating element 2 disposed in the drying box 1, and a feed port 11 and a discharge port 12 respectively formed at the ends of the drying box 1 along its length. Several guide rods 3 are distributed in the drying box 1 along the conveying direction of the polyester fibers. This embodiment uses three guide rods 3 as an example. Each guide rod 3 is fixedly mounted on the inner side wall of the drying box 1 perpendicular to the conveying direction of the polyester fibers. Each guide rod 3 is provided with a rotating sleeve 31, and a plurality of comb teeth 311 are evenly and fixedly arranged on the outer peripheral wall of the rotating sleeve 31 along the circumferential direction. Each guide rod 3 is also provided with a toggle mechanism 4 that drives the rotating sleeve 31 to slide back and forth along its own central axis.

[0034] Reference Figures 1 to 3The heating element 2 is used to dry the polyester fiber transported in the drying box, and the polyester fiber passes through the three rotating sleeves 31 in sequence during the transportation process, and drives the rotating sleeve 31 to rotate during the transportation process. The rotating sleeve 31 rotates to allow the comb teeth 311 on the outer wall of the rotating sleeve 31 to comb the polyester fiber. In the process of the comb teeth 311 combing the polyester fiber, the toggle mechanism 4 drives the rotating sleeve 31 to slide back and forth along its own central axis, so that the comb teeth 311 can toggle the polyester fiber in the transportation process back and forth, so that the polyester fiber is fully in contact with the hot air in the drying box 1, effectively reducing the possibility of fiber adhesion due to accumulation during the drying process.

[0035] Reference Figure 1 and Figure 2 Two parallel guide rollers 5 are rotatably provided at the feed port 11 of the drying box 1. The guide rollers 5 are rotatably provided on opposite side walls of the feed port 11 along the two sides of the polyester fiber conveying direction. A humidity sensor 6 is fixedly provided on the side wall of the drying box 1 at the discharge port 12.

[0036] Reference Figure 2 and Figure 3 The heating element 2 includes a hot air blower 21 and an air distribution plate 22. The hot air blower 21 is fixedly arranged on the top of the drying box 1. The air distribution plate 22 is arranged in an arc shape, and its arc center is located below itself. The center line of the arc center is arranged parallel to the conveying direction of the polyester fiber. The distance between the two sides of the air distribution plate 22 parallel to its own length direction exceeds the length dimension of the feed port 11.

[0037] Reference Figure 1 and Figure 2 A warm air cavity 221 is defined within the air distribution plate 22. Several air outlet holes 222 are arranged on the bottom wall of the air distribution plate 22, connecting to the warm air cavity 221. The air outlet of the hot air blower 21 is connected to the warm air cavity 221. A thermometer 7 is also fixed to the air distribution plate 22 and plugged into the warm air cavity 221. A controller 8 is fixed to the outer wall of the drying chamber 1. The thermometer 7 and the hot air blower 21 are both electrically connected to the controller 8.

[0038] Reference Figure 3 The rotating sleeve 31 sleeved on the guide rod 3 slides with the guide rod 3, and the toggle mechanism 4 includes an elastic member 41 and a driving assembly 42. The elastic member 41 in this embodiment is a compression spring, which is sleeved on one side end of the guide rod 3 and abuts against the rotating sleeve 31 and the opposite side wall of the drying box 1.

[0039] Reference Figure 2 and Figure 3The drive assembly 42 includes an eccentric 421 and a drive motor 422. The rotating shaft of the eccentric 421 is perpendicular to the length of the guide rod 3 and is rotatably mounted on the end of the guide rod 3 away from the compression spring. During rotation, the eccentric 421 always contacts the side wall of the rotating sleeve 31. The rotating shafts of the three eccentrics 421 are parallel to each other, and a synchronous pulley 9 is fixedly mounted on the rotating shaft of each eccentric 421. The three synchronous pulleys 9 are meshed with a synchronous belt 91, and the rotation angles of adjacent eccentrics 421 are inconsistent. The drive motor 422 is fixedly mounted on the inner side wall of the drying box 1 and is coaxially fixedly connected to the rotating shaft of one of the eccentrics 421.

[0040] The working principle of the drying device for polyester staple fibers in the embodiment of the present application is as follows: under the monitoring of the controller 8 and the thermometer 7, the hot air blower 21 inputs warm air into the air distribution plate 22. The warm air in the air distribution plate 22 is evenly distributed and discharged from the air outlet holes 222 to dry the polyester fibers transported in the drying box.

[0041] The polyester fiber passes through the three rotating sleeves 31 in sequence during the transportation process, and drives the rotating sleeve 31 to rotate during the transportation process. The rotation of the rotating sleeve 31 allows the comb teeth 311 on the outer wall of the rotating sleeve 31 to comb the polyester fiber.

[0042] And in the process of combing the polyester fibers with the comb teeth 311, under the action of the synchronous belt 91, the driving motor 422 drives the eccentric wheels 421 with inconsistent adjacent rotation angles to move synchronously, and under the coordinated action of the elastic member 41, pushes the rotating sleeve 31 to slide back and forth along the guide rod 3, so that the comb teeth 311 can move the polyester fibers in the conveying process back and forth, so that the polyester fibers are fully in contact with the hot air in the drying box 1, effectively reducing the possibility of fibers sticking together due to accumulation during the drying process.

[0043] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
