Description

Technical Field

[0001] This utility model belongs to the field of polyester POY production technology, and in particular relates to a drying device for polyester POY production. Background Technology

[0002] Polyester POY is a partially oriented synthetic fiber filament supported by a high-speed spinning process. Polyester POY is favored for its good dimensional stability, excellent strength and abrasion resistance, and high color fastness. During the production of polyester POY, the material needs to be cleaned and screened to remove residual oils and impurities from the spinning process, ensuring its performance in subsequent processing. Because moisture adheres to the polyester POY during cleaning and screening, drying equipment is required to reduce its moisture content and prevent air bubbles or filament breakage during production.

[0003] A search revealed a rapid drying device for polyester POY disclosed in patent publication number CN217465268U. The device includes a base plate with side plates fixed to both the front and rear sides of its upper surface. A first guide roller, a second guide roller, and a yarn-separating wheel are rotatably connected between the two side plates. A heater is fixed to the surface of each side plate, and a three-way pipe is fixed to the left end of the heater. A first fan and a second fan are fixed to the other two ends of the three-way pipe, respectively. A first air outlet pipe is fixed to the outlet end of the first fan, and a second air outlet pipe is fixed to the outlet end of the second fan. A pressing mechanism is installed between the two side plates. This pressing mechanism separates the polyester filament bundles, allowing the individual filaments within the bundles to be exposed and dried, thus solving the problem of incomplete drying. The filter tube, with its outer mesh and inner dust-proof cotton, blocks moisture and dust from the air, ensuring the dryness and cleanliness of the polyester filaments.

[0004] However, existing rapid drying equipment for polyester POY still has the following shortcomings in practical use: 1. First, side plates are symmetrically installed on the upper surface of the base plate. Two push shafts are slidably connected between the two side plates. A first extrusion plate is fixed to one push shaft, and a second extrusion plate is fixed to the other push shaft. A rough surface layer is fixed to the first and second extrusion plates. A motor is installed on one side plate. Support rods are fixed to both sides of the motor. A first incomplete turntable and a second incomplete turntable are rotatably connected to the support rods. The output shaft of the motor and the rotating shaft on the support rods are connected by a transmission belt. When the motor is powered on, the first and second incomplete turntables rotate, pushing the two push shafts to slide, causing the first and second extrusion plates to move and separate the polyester POY for efficient drying. However, since the position of the rough surface layer is fixed, the friction between the polyester POY and the rough surface layer increases during the movement, causing wear on the polyester POY and reducing its quality. 2. Secondly, after the polyester POY is separated by the first and second extrusion plates, the separated polyester POY needs to be transported and dried by the same conveyor belt during the subsequent drying process. Since the surface of the conveyor belt is smooth and flat, it is difficult to limit the path of the polyester POY. Some polyester POY transported in the same way will get close to each other and mix, or even get tangled and knotted, which will cause inconvenience to the transportation of the dried polyester POY and may even require machine shutdown for sorting, which will affect the drying efficiency of the polyester POY.

[0005] To address these issues, we provide a drying device for polyester POY production. Utility Model Content

[0006] The purpose of this utility model is to provide a drying device for polyester POY production. By setting up a bundling component, the polyester POY is separated into individual strands, which facilitates efficient and thorough drying of the polyester POY. At the same time, it reduces the friction between the anti-slip cylinder and the polyester POY, reducing wear. Furthermore, by setting up a drying component, the separated polyester POY is dried while avoiding tangling and knotting, making it easier to transport the dried polyester POY to the next station. This solves the technical problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a drying device for polyester POY production, comprising a base plate, support plates symmetrically mounted on the upper surface of the base plate, a bundle-splitting assembly provided on the upper surface of the base plate, the bundle-splitting assembly including a motor mounted on the outer wall of the support plate, a drive shaft and a driven shaft rotatably connected between the two support plates, the output end of the motor being connected to the end of the drive shaft, internally threaded cylinders threadedly connected to the drive shaft and the driven shaft being staggered, and an anti-slip cylinder being rotatably connected to the outer circumference of the internally threaded cylinder; a drying assembly is provided above the base plate, the drying assembly including branch pipes equidistantly connected and fixed to the side wall of the main air pipe, and a drying pipe being horizontally connected and fixed to the lower end of the branch pipe.

[0008] The present invention is further configured such that a rectangular array of support feet are installed on the lower surface of the base plate, a top plate is installed on the upper surface of the two support plates, an inlet groove is provided on the top plate, and the upper end of the main air pipe penetrates through the top plate.

[0009] The present invention is further configured such that guide rollers are provided above both the drive shaft and the driven shaft, both ends of the guide rollers are rotatably connected to the support plate, and threaded bodies are provided in the middle of the outer periphery of both the drive shaft and the driven shaft.

[0010] The present invention is further configured such that a guide rod is installed between the two support plates, and the guide rod passes through the internally threaded cylinder.

[0011] The present invention is further configured such that threaded sleeves are symmetrically threaded at both ends of the internal threaded cylinder, and ball bearings are connected in an annular array at both ends of the anti-slip cylinder, with the ball bearings abutting against the side wall of the threaded sleeve.

[0012] The present invention is further configured such that a driving gear is fixedly connected to the circumference of the driving shaft, a driven gear is fixedly connected to the circumference of the driven shaft, a toothed belt is meshed between the driving gear and the driven gear, and a protective shell sleeved on the outside of the toothed belt is installed on the side wall of the support plate.

[0013] The present invention is further configured such that a rotating shaft is provided below the drive shaft, both ends of the rotating shaft are rotatably connected to the support plate, a sleeve is fixedly connected to the circumference of the rotating shaft, and the sleeve is provided with splitting grooves at equal intervals on the circumference of the sleeve.

[0014] The present invention is further configured such that crossbeams are equidistantly connected to the lower surface of the drying tube, and both ends of the crossbeams are installed on the inner wall of the support plate.

[0015] This utility model has the following beneficial effects: 1. This utility model, by setting up a bundle-splitting assembly, allows polyester POY passing through the inlet groove to be guided by two guide rollers and then through the gap between two anti-slip cylinders. When the motor is energized, the drive shaft rotates, driving the drive gear, toothed belt, driven gear, and driven shaft to rotate. This causes the two internally threaded cylinders to reciprocate and shift under the guidance of the guide rod, which in turn causes the two anti-slip cylinders to reciprocate and shift, thus separating the polyester POY. This facilitates efficient and thorough drying of the polyester POY by the drying assembly, improving the drying effect. At the same time, the moving polyester POY applies an external force to the anti-slip cylinders, causing the anti-slip cylinders to rotate on the internally threaded cylinders, reducing the friction between the anti-slip cylinders and the polyester POY, reducing wear on the polyester POY, and improving the quality of the dried polyester POY.

[0016] 2. This utility model, by setting up a drying component, allows the separated polyester POY to enter the drying tube through a bundling groove. The fan on the main air pipe and the hot air pipe is connected and fixed. When the fan is powered on, hot air enters the drying tube through the main air pipe and the branch air pipe. The polyester POY comes into contact with the hot air and is dried. At the same time, the drying tube limits the path of the polyester POY, preventing the separated polyester POY from mixing again and preventing the polyester POY from tangling and knotting. This facilitates the transportation of the dried polyester POY to the next work station. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1 Please see Figure 1 This utility model is a drying equipment for polyester POY production, including a bottom plate 1, a support plate 102, a top plate 103 and an inlet groove 103a. The support plate 102 is used to support the top plate 103, so that there is space for mounting components between the top plate 103 and the bottom plate 1. The inlet groove 103a is used for polyester POY to pass through the top plate 103. Specifically, support plates 102 are symmetrically installed on the upper surface of the base plate 1, and a top plate 103 is installed on the upper surface of the two support plates 102. An inlet groove 103a is opened on the top plate 103, and the upper end of the main air pipe 301 passes through the top plate 103. Furthermore, a rectangular array of support feet 101 is mounted on the lower surface of the base plate 1; The operation process of this embodiment is as follows: the polyester POY is introduced from above the top plate 103 through the inlet groove 103a and introduced below the top plate 103. The polyester POY is separated by the bundling assembly 2. The separated polyester POY is dried by the drying assembly 3. The dried polyester POY enters the next station.

[0022] Example 2 Please see Figure 1 , Figure 2 , Figure 3 and Figure 4Based on the first specific embodiment, a bundle splitting assembly 2 is provided. The bundle splitting assembly 2 includes a motor 201, a driven shaft 203, a drive shaft 205, an internal threaded cylinder 208, and an anti-slip cylinder 209. When the motor 201 is energized, the driven shaft 203 and the drive shaft 205 rotate, causing the two internal threaded cylinders 208 to move out of position, which in turn drives the two anti-slip cylinders 209 to move back and forth out of position, thus splitting the polyester POY. This facilitates the drying assembly 3 to dry the separated polyester POY efficiently and thoroughly. At the same time, the rotation of the anti-slip cylinder 209 guides the polyester POY, effectively reducing the friction between the protective cylinder 209 and the polyester POY, reducing wear, and improving the quality of the dried polyester POY. Specifically, the motor 201 is mounted on the outer wall of the support plate 102. The two support plates 102 are rotatably connected by a drive shaft 205 and a driven shaft 203. The output end of the motor 201 is connected to the end of the drive shaft 205. The internally threaded cylinders 208 threadedly connected to the drive shaft 205 and the driven shaft 203 are staggered. The outer circumference of the internally threaded cylinders 208 is rotatably connected to an anti-slip cylinder 209. Furthermore, guide rollers 202 are provided above both the drive shaft 205 and the driven shaft 203. Both ends of the guide rollers 202 are rotatably connected to the support plate 102 to guide the polyester POY. Threaded bodies are provided at the center of the outer periphery of both the drive shaft 205 and the driven shaft 203 to drive the internal threaded cylinder 208 to move. A guide rod is installed between the two support plates 102, passing through the internal threaded cylinder 208 to prevent the internal threaded cylinder 208 from rotating with the drive shaft 205 and the driven shaft 203. Threaded sleeves 208a are symmetrically threaded at both ends of the internal threaded cylinder 208 to prevent the anti-slip cylinder 209 from detaching from the internal threaded cylinder 208. The anti-slip cylinder 209 is arranged in a ring array at both ends. A ball bearing 209a is connected and abuts against the side wall of the threaded sleeve 208a to reduce friction. A drive gear 207a is fixed to the circumference of the drive shaft 205, and a driven gear 207b is fixed to the circumference of the driven shaft 203. A toothed belt 207 meshes between the drive gear 207a and the driven gear 207b. A protective shell 206 is fitted on the outside of the toothed belt 207 and installed on the side wall of the support plate 102. A rotating shaft 204 is provided below the drive shaft 205. Both ends of the rotating shaft 204 are rotatably connected to the support plate 102. A sleeve 204a is fixed to the circumference of the rotating shaft 204, and a splitting groove 204b is equidistantly opened on the circumference of the sleeve 204a. The operation process of this embodiment is as follows: the polyester POY passing through the through groove 103a passes downward through the gap between the two guide rollers 202, and then passes through the gap between the two anti-slip cylinders 209. The motor 201 is energized, the drive shaft 205 rotates, the drive gear 207a rotates, causing the toothed belt 207 to drive the driven gear 207b to rotate. Through the guidance and limitation of the guide rod, the two internal threaded cylinders 208 move back and forth in a staggered manner, driving the two anti-slip cylinders 209 to move back and forth in a staggered manner, thus performing thread separation processing on the polyester POY. During the movement, the polyester POY applies external force to the anti-slip cylinder 209, the ball 209a moves on the threaded sleeve 208a, causing the protective cylinder 209 to rotate, guiding the separated polyester POY into the bundling groove 204b. The moving polyester POY applies external force to the sleeve 204a, the driven shaft 203 rotates, and the polyester POY is guided.

[0023] Example 3 Please see Figure 1 and Figure 2 Based on specific embodiments one and two, a drying component 3 is provided. The drying component 3 includes a main air pipe 301, a branch air pipe 302 and a drying pipe 303. Hot air enters the drying pipe 303 through the main air pipe 301 and the branch air pipe 302 to dry the polyester POY inside the drying pipe 303. At the same time, the drying pipe 303 limits the path of the separated polyester POY to prevent the separated polyester POY from mixing together again, which is conducive to the normal transportation of the dried polyester POY. Specifically, the bronchus 302 is equidistantly connected and fixed to the side wall of the main bronchus 301, and the lower end of the bronchus 302 is horizontally connected and fixed to the drying tube 303. Furthermore, the lower surface of the drying tube 303 is equidistantly connected with crossbeams 304. Both ends of the crossbeams 304 are installed on the inner wall of the support plate 102. The crossbeams 304 are used to support the drying tube 303 and improve the stability of the drying tube 303. The operation process of this embodiment is as follows: the upper end of the main air pipe 301 is connected and fixed to the fan on the hot air pipe. The fan is powered on, so that the hot air inside the hot air pipe enters the drying pipe 303 through the main air pipe 301 and the branch air pipe 302. The polyester POY that has passed through the bundled groove 204b enters the drying pipe 303 and comes into contact with the hot air inside the drying pipe 303 to achieve the drying treatment of polyester POY.
