Description

Technical Field

[0001] This utility model relates to the field of nylon filament drawing technology, specifically a filament drawing device for the production of nylon plastic granules. Background Technology

[0002] Nylon is a type of polyamide compound based on aliphatic or semi-aromatic compounds. In the production process of nylon filaments, in order to improve the strength and toughness of the material, it is usually necessary to use a drawing device to stretch the nylon filaments.

[0003] A Chinese patent with authorization announcement number CN 209426161 U discloses a wire drawing device based on nylon plastic granules. The device includes a base, a main body fixedly mounted on top of the base, a top box fixedly mounted on top of the main body, a stretching box fixedly mounted on the right side of the main body on top of the base, a drive box fixedly mounted on the right side of the stretching box on top of the base, and a dust treatment box fixedly mounted on the front of the main body. This wire drawing device, by incorporating a top box, an exhaust port, and an exhaust fan, sequentially extracts the wire drawing dust from the nylon plastic granules through a vertical pipe, a connecting pipe, and the exhaust port, then transports it to the interior of the top box. Since the exhaust port faces downwards, the wire drawing dust comes into contact with water inside the top box, thus achieving dust treatment and increasing the practicality of the device.

[0004] Existing drawing devices for nylon filaments often fail to effectively remove impurities from the raw materials, resulting in burrs that are prone to form during the drawing process. This leads to poor impurity removal and affects the quality of the nylon filaments. Therefore, a drawing device for nylon plastic granule production is proposed to address these issues. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems existing in the existing technology, this utility model proposes a drawing device for the production of nylon plastic granules.

[0006] The technical solution adopted by this utility model to solve its technical problem is a drawing device for producing nylon plastic granules, including a base, an extrusion assembly mounted on the base, an extrusion assembly including a fixed platform, an extruder fixedly mounted on the fixed platform, a feeding box mounted on the extruder, a hopper mounted on the top plate of the feeding box, a storage cylinder mounted on the inner wall of the feeding box, multiple discharge slots opened on the bottom of the storage cylinder, a first guide component and a second guide component mounted on the bottom plate of the storage cylinder, a first dust suction component and a second dust suction component mounted on the bottom side of the storage cylinder, the first dust suction component and the second dust suction component are annular structures, the first dust suction component and the second dust suction component have cavities inside, multiple dust suction holes are opened on the inner wall of the first dust suction component and the outer wall of the second dust suction component, a dust suction pipe is connected to the bottom of the first dust suction component and the second dust suction component, and a dust suction box is installed at the other end of the dust suction pipe. The dust collection box contains a dust collection container, with a handle installed on its outer wall and filter holes on its side wall. An exhaust box is installed on the side wall of the dust collection box, and exhaust slots are formed on both side walls of the exhaust box and the side wall of the dust collection box. A drive motor is mounted inside the exhaust box via a base, and a rotor with fan blades is mounted on its output shaft. Nylon plastic granules are poured from the hopper into the feeding box, then enter the storage cylinder. Guided by the first and second guide components, the nylon plastic granules fall sequentially from the discharge chute between the first and second dust collection components. The first and second dust collection components effectively remove impurities from the surface of the nylon plastic granules, preventing impurities from being present in the raw materials, improving the impurity removal effect, and ultimately enhancing the quality of the nylon filaments.

[0007] Preferably, a first motor is mounted on the side wall of the extruder, and a screw is mounted on the output shaft of the first motor. The screw is rotatably mounted on the inner wall of the extruder. A heating plate is installed inside the side wall of the extruder. A spinneret is mounted on the extruder, and the spinneret has multiple micro-holes. A drawing assembly is mounted on the base. The drawing assembly includes a support frame, and multiple second motors are mounted on the support frame via a base. Drawing rollers are mounted on the output shafts of the second motors, and one of the drawing rollers has multiple dividing grooves. A winding assembly is mounted on the base. The winding assembly includes a fixing frame, and multiple guide rollers are rotatably mounted on the fixing frame via a base. There are multiple third motors, and a take-up roller is installed on the output shaft of the third motor. A take-up drum is installed on the take-up roller. Control panels are installed on the fixed frame, support frame, and fixed platform. After the nylon plastic granules are melted by the machine, they are uniformly extruded from the spinneret. The extruded molten filaments are quickly cooled and solidified. Then, the nylon filaments are wound around the drawing rollers in sequence. The multi-stage drawing roller group works together to gradually stretch the nylon filaments. Each nylon filament is located in a dividing groove, which realizes the limiting of the nylon filaments. Then, each nylon filament is wound around a take-up drum, and the take-up drum winds up the nylon filaments. During this process, multiple nylon filaments can be neatly arranged, which helps to improve the uniformity of the nylon filaments.

[0008] The advantages of this utility model are:

[0009] 1. This utility model involves pouring nylon plastic granules from a hopper into a feeding box, and then the nylon plastic granules enter a storage cylinder. Guided by a first and a second guide component, the nylon plastic granules fall sequentially from the discharge trough between a first and a second dust suction component. The first and second dust suction components suction out impurities from the surface of the nylon plastic granules, effectively removing impurities from the surface of the nylon plastic granules, avoiding impurities in the raw materials, improving the impurity removal effect of the raw materials, and improving the quality of nylon filaments.

[0010] 2. In this invention, nylon plastic granules are melted and then uniformly extruded from a spinneret. The extruded molten filaments are rapidly cooled and solidified. The nylon filaments are then wound sequentially onto drawing rollers. A multi-stage drawing roller assembly works together to gradually stretch the nylon filaments. Each nylon filament is located in a separating groove, which limits the position of the nylon filament. Then, each nylon filament is wound onto a take-up drum, which takes the nylon filaments in place. During this process, multiple nylon filaments can be neatly arranged, which helps to improve the uniformity of the nylon filaments. Attached Figure Description

[0018] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figure 1-5As shown, a drawing device for producing nylon plastic granules includes a base 1, on which an extrusion assembly is mounted. The extrusion assembly includes a fixed platform 2, on which an extruder 3 is fixedly mounted. A feeding box 4 is mounted on the extruder 3, and a hopper 5 is mounted on the top plate of the feeding box 4. A storage cylinder 6 is mounted on the inner wall of the feeding box 4. Multiple discharge slots 7 are opened on the bottom of the storage cylinder 6. A first guide component 8 and a second guide component 9 are mounted on the bottom plate of the storage cylinder 6. A first dust suction component 10 and a second dust suction component 11 are mounted on the bottom side of the storage cylinder 6. The first dust suction component 10 and the second dust suction component 11 have annular structures, and cavities are opened inside the first dust suction component 10 and the second dust suction component 11. Multiple suction holes 12 are provided on the outer wall of component 11. A suction pipe 13 is connected to the bottom of the first suction component 10 and the second suction component 11. A suction box 14 is installed at the other end of the suction pipe 13. A suction box 15 is placed inside the suction box 14. A handle is installed on the outer wall of the suction box 15. Filter holes are provided on the side wall of the suction box 15. An exhaust box 16 is installed on the side wall of the suction box 14. Exhaust slots are provided on the two side walls of the exhaust box 16 and the side wall of the suction box 14. A drive motor 17 is installed inside the exhaust box 16 via a base. A rotor is installed on the output shaft of the drive motor 17, and fan blades 18 are installed on the rotor. During operation, existing drawing devices, in the process of drawing nylon filaments, have difficulty removing impurities from the raw materials. To effectively remove impurities, burrs are easily generated during the drawing process, resulting in poor impurity removal of raw materials and affecting the quality of nylon filaments. Nylon plastic granules are poured from hopper 5 into feeding box 4, and then enter storage cylinder 6. Guided by the first guide component 8 and the second guide component 9, the nylon plastic granules fall successively from discharge chute 7 between the first suction component 10 and the second suction component 11. During their passage through the inner wall of the first suction component 10 and the second suction component 11, the drive motor 17 operates, driving the rotor to rotate at high speed. The rotor drives the fan blades 18 to rotate at high speed, causing the air inside the dust collection box 14, suction pipe 13, first suction component 10, and second suction component 11 to instantly escape through the exhaust chute. The dust and impurities on the nylon plastic particles falling between the vacuum box 14, vacuum pipe 13, first vacuum component 10, and second vacuum component 11 are drawn into the vacuum box 14 along with the air due to the pressure difference between them and the outside environment. The impurities are then intercepted by the filter plate on the side wall of the vacuum box 15, and clean air is discharged from the exhaust duct. This process effectively cleans the impurities on the surface of the nylon plastic particles. The cooperation between the first vacuum component 10 and the second vacuum component 11 effectively removes impurities from the surface of the nylon plastic particles, preventing impurities from being present in the raw materials, improving the impurity removal effect, and ultimately enhancing the quality of the nylon filaments.

[0020] Please see Figure 1As shown, a first motor is installed on the side wall of the extruder 3, and a screw is installed on the output shaft of the first motor. The screw is rotatably mounted on the inner wall of the extruder 3. A heating plate is installed inside the side wall of the extruder 3. A spinneret 26 is installed on the extruder 3, and multiple micro-holes are installed on the spinneret 26. A wire drawing assembly is installed on the base 1. The wire drawing assembly includes a support frame 19. Multiple second motors are installed on the support frame 19 via a base. Wire drawing rollers 20 are installed on the output shafts of the second motors. One of the wire drawing rollers 20 has multiple... The base 1 has a base 1 with a groove 21 and a winding assembly. The winding assembly includes a fixed frame 22, on which multiple guide rollers 23 are rotatably mounted. Multiple third motors are mounted on the fixed frame 22 via a machine base. A winding roller 24 is mounted on the output shaft of the third motor, and a winding drum 25 is mounted on the winding roller 24. Control panels are mounted on the fixed frame 22, the support frame 19, and the fixed platform 2, respectively. During operation, existing drawing devices have difficulty arranging multiple nylon filaments neatly during the stretching process, resulting in... The nylon filaments have poor uniformity. Nylon plastic granules enter the extruder 3 from the feed box 4. The extruder 3 melts the nylon plastic granules, while the first motor drives the screw to rotate. The screw evenly extrudes the molten material from the spinneret 26. The extruded molten filaments cool and solidify rapidly. The nylon filaments then wind sequentially around the drawing rollers 20. Multiple third motors operate, driving multiple drawing rollers 20 to rotate. However, the speeds of the multiple third motors are different. The multi-stage drawing rollers 20 work together to gradually stretch the nylon filaments, achieving rapid stretching of the nylon filaments. Rapid stretching allows the nylon filaments to achieve the required diameter and strength. Each nylon filament is positioned within a separator groove 21, which limits its movement and allows multiple nylon filaments to be neatly arranged. Each nylon filament is then wound onto a take-up drum 25. A third motor drives a take-up roller 24 to rotate, which in turn drives the take-up drum 25 to rotate. The take-up drum 25 then winds up the nylon filaments, achieving efficient winding. During this process, multiple nylon filaments can be neatly arranged, which helps improve the uniformity of the nylon filaments.

[0021] Working principle: Existing drawing devices struggle to effectively remove impurities from the raw materials during nylon filament drawing, resulting in burrs and poor impurity removal, thus affecting the quality of the nylon filaments. In this new device, nylon plastic granules are poured from the hopper 5 into the feeding box 4, then into the storage cylinder 6. Guided by the first guide component 8 and the second guide component 9, the nylon plastic granules fall sequentially from the discharge trough 7 between the first suction component 10 and the second suction component 11. As they pass through the inner wall of the first suction component 10 and the second suction component 11, the drive motor 17 operates, causing the rotor to rotate at high speed. The rotor then drives the fan blades. The high-speed rotation of component 18 causes the air inside the dust collection box 14, suction pipe 13, first suction component 10, and second suction component 11 to be instantly discharged from the exhaust channel. A pressure difference exists between the dust collection box 14, suction pipe 13, first suction component 10, and second suction component 11 and the outside environment. Under the action of this pressure difference, dust and impurities on the nylon plastic particles falling between the first and second suction components 10 are sucked into the dust collection box 15 of the dust collection box 14 along with the air. The impurities are then intercepted by the filter plate on the side wall of the dust collection box 15, and clean air is discharged from the exhaust channel, thus cleaning the impurities on the surface of the nylon plastic particles. Due to the cooperation of the first and second suction components 10... This method effectively removes impurities from the surface of nylon plastic granules, preventing impurities from being present in the raw materials, thus improving the impurity removal effect and the quality of nylon filaments. Existing drawing devices struggle to neatly arrange multiple nylon filaments during the stretching process, resulting in poor filament uniformity. Nylon plastic granules enter the extruder 3 from the feeding box 4, where the extruder 3 melts the nylon plastic granules. Simultaneously, the first motor drives the screw to rotate, and the screw evenly extrudes the molten material from the spinneret 26. The extruded molten filaments quickly cool and solidify, then the nylon filaments are sequentially wound onto the drawing rollers 20. Multiple third motors operate, driving multiple drawing rollers... The yarn roller 20 rotates, but the speeds of the multiple third motors are different. The multi-stage drawing rollers 20 work together to gradually stretch the nylon yarn, achieving rapid stretching of the nylon yarn and enabling it to obtain the required yarn diameter and strength. Each nylon yarn is located in a separator groove 21, which limits the movement of the nylon yarn and allows multiple nylon yarns to be arranged neatly. Then, each nylon yarn is wound onto a take-up drum 25. The third motor drives the take-up roller 24 to rotate, and the take-up roller 24 drives the take-up drum 25 to rotate. The take-up drum 25 winds up the nylon yarn, achieving efficient winding of the nylon yarn. During this process, multiple nylon yarns can be arranged neatly, which helps to improve the uniformity of the nylon yarn.
