Description

Technical Field

[0001] This utility model relates to the field of spinning processing technology, and in particular to a double-spindle winding device. Background Technology

[0002] The fully automatic spinning and winding equipment with dual extruders is the core device for realizing continuous and intelligent fiber production in the textile industry. By integrating functions such as melt extrusion, yarn guiding and shaping, high-speed winding and automatic bobbin changing, the winding device is the key equipment for realizing the transformation from raw materials to finished yarn cakes.

[0003] The winding device mainly consists of an active reel that provides winding power, a tension control system that maintains stable material tension, a guide mechanism that guides the material to be evenly distributed, a drive and control system that regulates the overall operation, and a roll diameter detection module that monitors the roll diameter in real time. Through the rotation of the reel, it realizes the continuous winding or unwinding of long strip materials such as cables, fibers, films, and metal strips. Traditional reel devices only contain one reel, and the machine must be stopped when the reel is fully wound. When the reel is wound to the preset full roll state, the machine must be stopped to complete the process of cutting the material, unloading the full roll, installing the empty reel, and fixing the material end. The winding process is subject to forced interruption, the degree of automation is low, and key steps rely on manual intervention, which indirectly increases operating costs and greatly reduces production efficiency. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a dual-spindle winding device, which aims to improve the problem that the existing single-spindle winding device has a low degree of automation, relies on manual intervention to complete key steps, indirectly increases operating costs, and greatly reduces production efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a dual-spindle winding device, comprising a housing, wherein a dual-spindle switching mechanism is provided inside the housing, the dual-spindle switching mechanism being used to switch the take-up roller; the dual-spindle switching mechanism includes a turntable, the turntable being rotatably connected to the front middle of the housing, a rotating shaft being fixedly connected to the front side of the outer wall of the turntable, a gear ring being fixedly connected to the front side of the outer wall of the turntable, a switching motor being installed in the middle of the rear side of the inner wall of the housing, a spur gear being fixedly connected to the output end of the switching motor, the outer wall of the spur gear meshing with the outer wall of the gear ring, and rotating components being provided at both the upper and lower ends of the turntable.

[0006] As a further description of the above technical solution:

[0007] The rotating assembly at the upper end includes a fixed plate, which is threadedly connected to the upper inner end of the turntable. A rotating motor is threadedly connected to the rear side of the fixed plate, and a take-up roller is fixedly connected to the output end of the rotating motor.

[0008] As a further description of the above technical solution:

[0009] A support platform is installed on the outer side of the outer shell, and a spinning unit is installed in the middle of the top wall of the support platform.

[0010] As a further description of the above technical solution:

[0011] A partition is fixedly connected to the center of the front side of the turntable.

[0012] As a further description of the above technical solution:

[0013] Support tubes are fixedly connected to the front and rear sides of the bottom of the outer shell. Multiple connecting plates are fixedly connected to adjacent sides of the support tubes. A roller is rotatably connected to the right end of the inner wall of the support tube. Multiple bolts are threadedly connected to the inner bottom wall of the support tube.

[0014] As a further description of the above technical solution:

[0015] A fixing rod is threadedly connected to the middle right side of the inner wall of the outer casing, and a conductive slip ring assembly is fixedly connected to the left end of the fixing rod.

[0016] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the end of the filament bundle is connected to the take-up roller. The upper rotating motor is started to make the take-up roller rotate. When the take-up roller rotates, it winds the fiber bundle into a finished filament cake. When the take-up roller is fully wound, the switching motor is started to make the spur gear rotate, which drives the gear ring to rotate. The gear ring drives the turntable to rotate inside the rotating shaft, switching the upper fully wound take-up roller to the lower one, and the lower empty take-up roller to the upper one to continue winding the fiber bundle. This solves the problem that the single roll device needs to stop to change rolls when in use, and improves production efficiency.

[0022] 2. In this utility model, the raw material is poured into the hopper, and the raw material is melted and extruded by the screw through the extruder and pushed to the metering pump in the spinning unit. At the same time, the reducer is turned on to control the melt flow rate in the metering pump. The melt passes through the composite spinning cup-shaped component and the multi-hole spinneret to form the nascent fiber bundle. Then, the fiber bundle is guided and shaped by the guide plate, making the production of fiber bundles faster and greatly improving production efficiency. Attached Figure Description

[0032] 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 protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a dual-spindle winding device, comprising a housing 1, inside which a dual-spindle switching mechanism 2 is provided for switching take-up rollers 2063; the dual-spindle switching mechanism 2 includes a turntable 201, which is rotatably connected to the front center of the housing 1, a rotating shaft 202 is fixedly connected to the front side of the outer wall of the turntable 201, and a gear ring 203 is fixedly connected to the front side of the outer wall of the turntable 201 to drive the turntable 201 to rotate; a switching motor 204 is installed in the middle of the rear side of the inner wall of the housing 1, the switching motor 204 is a NEMA34 model, which, through input electrical pulse signals, causes the stator winding to be energized in a specific sequence to generate a rotating magnetic field, driving the rotor to rotate at a fixed angle, and by controlling the pulse sequence and frequency, forward and reverse rotation, speed adjustment and precise positioning are achieved; a spur gear is fixedly connected to the output end of the switching motor 204. 205, the outer wall of the spur gear 205 meshes with the outer wall of the gear ring 203. The upper and lower ends of the turntable 201 are provided with rotating components 206. The upper rotating component 206 includes a fixing plate 2061, which is threaded to the upper end of the turntable 201. The rear side of the fixing plate 2061 is threaded with a rotating motor 2062. The rotating motor 2062 is a 1FT7 model. After receiving the control signal through the servo system, the rotor rotates and the position and speed are fed back in real time through the encoder. The controller compares the command and the feedback, and adjusts the output signal to make the rotor accurately follow the command to achieve high-precision speed regulation and positioning, which drives the take-up roller 2063 to rotate. The output end of the rotating motor 2062 is fixedly connected to the take-up roller 2063 for winding fiber bundles. A partition 5 is fixedly connected to the middle of the front side of the turntable 201 to prevent dust and impurities from entering the interior of the outer shell 1.

[0034] Specifically, the fiber bundle ends to be processed are first connected to the upper take-up roller 2063 to ensure that the fiber bundle ends will not fall off during the take-up process. Then, the upper rotary motor 2062 is started, which drives the connected take-up roller 2063 to rotate at a constant speed. During the rotation, the take-up roller 2063 slowly winds the fiber bundle, gradually winding the fiber bundle into a finished filament cake as the number of winding turns increases. When the fiber bundle wound by the take-up roller 2063 reaches a full roll, the rotary motor 204 is started. The rotary motor 204 operates, causing the connected spur gears to... When wheel 205 rotates, since spur gear 205 and gear ring 203 are in a meshing state, the rotation of spur gear 205 will drive gear ring 203 to rotate synchronously. Gear ring 203 drives the turntable 201 connected to it to rotate inside the rotating shaft 202. When turntable 201 rotates, it will switch the upper winding roller 2063 to the lower position and at the same time switch the lower winding roller 2063 to the upper position. The upper winding roller 2063 continues to wind the fiber bundle. The whole process realizes the unmanned operation of the entire process from raw material to finished yarn cake, avoids the interruption of fiber bundle processing, and greatly improves production efficiency.

[0035] Reference Figure 5 and Figure 6 Support tubes 6 are fixedly connected to the bottom front and rear sides of the outer casing 1 to support the device. Multiple connecting plates 9 are fixedly connected to adjacent sides of the support tubes 6. Rollers 7 are rotatably connected to the right end of the inner wall of the support tubes 6 to facilitate the movement of the device. Multiple bolts 8 are threadedly connected to the inner bottom wall of the support tubes 6 to adjust the level of the device. A fixing rod 10 is threadedly connected to the middle right side of the inner wall of the outer casing 1. A conductive slip ring group 11 is fixedly connected to the left end of the fixing rod 10 to control the power of the switching motor 204.

[0036] Specifically, the support tube 6 at the bottom of the outer casing 1 provides stable support for the device, preventing it from tilting or shaking during operation. The roller 7 on the rear side of the support tube 6 facilitates the movement of the device. Rotating the bolt 8 at the bottom of the support tube 6 can change the height of the support tube 6 from the ground, thereby adjusting the overall level of the device and ensuring stable operation of the device in a horizontal state. This prevents differences in the collection progress of the front and rear yarn cakes on the take-up roller 2063. The conductive slip ring group 11 is used to control the power of the switching motor 204.

[0037] Reference Figure 1 , Figure 2 and Figure 7 A support platform 3 is installed on the outer side of the outer casing 1. A spinning unit 4 is installed in the middle of the top wall of the support platform 3 for guiding and shaping the yarn. Two metering pumps 12 are installed inside the spinning unit 4. The metering pumps 12 are model TDJLG. They are driven by a motor through a worm gear mechanism to reduce speed, which drives an eccentric wheel to make the plunger reciprocate in the pump chamber, thereby changing the volume of the pump chamber and realizing the suction and discharge of liquid. The flow rate can be precisely controlled by adjusting the plunger stroke. A reducer 13 is installed on the top of each of the two metering pumps 12. The reducer 13 is model PRF120. Through an internal gear pair The meshing transmission converts the high-speed rotation of the input shaft into the low-speed, high-torque rotation of the output shaft, thereby providing stable power to the metering pump 12 and accurately controlling the flow rate of the melt. The extruder 14 is installed on both the left and right sides of the spinning unit 4. The model of the extruder 14 is XDC-90. Through the rotation of the screw, the material is pushed forward from the feed port, and it is gradually transformed from solid to melt in the barrel by heating and friction. The material is used to extrude the melt. The right side of the outer wall of the right extruder 14 is connected to the hopper 15 for storing raw materials.

[0038] Specifically, the solid raw materials required for fiber production are first evenly poured into the hopper 15. After the raw materials enter the extruder 14 from the hopper 15, the extruder 14 starts and heats and melts the raw materials by rotating the internal screw, turning the raw materials into a melt. At the same time, the screw continues to rotate, pushing the molten raw materials into the metering pump 12 in the spinning unit 4. During this process, the reducer 13 is turned on simultaneously. The reducer 13 controls the operating speed of the metering pump 12, thereby controlling the flow rate of the melt output by the metering pump 12. Then, the melt is mixed and distributed through the composite spinning cup component in the spinning unit 4, and then extruded through the spinneret holes of the multi-hole spinneret to form a fiber bundle. The fiber bundle is then guided and stretched by the guide plate to prepare for subsequent processing steps.

[0039] Working principle: First, move the device directly under the support platform 3, rotate the bolt 8 to adjust the device to a horizontal state, pour the raw material into the hopper 15, and use the extruder 14 to melt and extrude the raw material through the screw and push it to the metering pump 12 in the spinning unit 4. At the same time, turn on the reducer 13 to control the melt flow rate in the metering pump 12, and use the melt to form the nascent fiber bundle through the composite spinning cup-shaped component and the multi-hole spinneret. Then, guide and shape the fiber bundle through the guide plate.

[0040] Then, the end of the filament bundle is connected to the take-up roller 2063, and the upper rotating motor 2062 is started to make the connected take-up roller 2063 rotate at a constant speed. During the rotation, the take-up roller 2063 will slowly wind the fiber bundle and roll it into a finished filament cake. When the take-up roller 2063 is wound to the preset full-wound state, the switching motor 204 is started to make the spur gear 205 rotate. Since the spur gear 205 and the toothed ring 203 are in a meshing state, the spur gear 205 will drive the toothed ring 203 to rotate synchronously. The toothed ring 203 drives the turntable 201 connected to it to rotate inside the rotating shaft 202, so that the upper full-wound take-up roller 2063 is switched to the lower, and the lower empty take-up roller 2063 is switched to the upper to continue winding the fiber bundle. This realizes the unmanned operation of the whole process from raw materials to finished filament cake, avoids the interruption of the processing, and improves production efficiency.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
