Description

Technical Field

[0001] This utility model relates to the technical field of fiber yarn production equipment, specifically a glass fiber yarn twisting device. Background Technology

[0002] As a high-performance reinforcing material, glass fiber yarn is widely used in aerospace, automobile manufacturing, wind turbine blades and other fields. However, the production process of glass fiber yarn often requires a twisting process.

[0003] A Chinese patent (publication number CN218754132U) discloses a yarn plying device, including a base box. A vertical plate is welded to the top of the base box, and a transmission motor for driving a take-up roller to rotate is fixedly connected to the right side of the surface of the vertical plate. A bearing for rotating a shaft is provided on one side of the take-up roller. A handle for rotating the shaft is welded to the back of the shaft. A bidirectional symmetrical screw is welded to the surface of the shaft, with both sides of the outer wall threaded to the screw sleeve. A guide rail for sliding a slider is welded to the top of the inside of the take-up roller. The top of the slider is fixedly connected to the bottom of the screw sleeve. A limit rod is welded to the top of each screw sleeve. A through groove for the limit rod to pass through is provided at the top of the take-up roller.

[0004] During use, the aforementioned plying device collects the plyed yarn by passing it through the threading hole on the connecting block and then winding it onto the winding roller. However, the inner diameter of the threading hole is not easy to adjust. When a large number of yarns need to be plyed at one time, it is often inconvenient to pass them through the threading hole with a small diameter, which affects the subsequent winding work.

[0005] To address this problem, we designed a glass fiber yarn twisting device. Utility Model Content

[0006] The purpose of this invention is to provide a glass fiber yarn twisting device to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides a glass fiber yarn twisting device, including a mounting base and a connecting shaft, a winding frame, and a winding roller sequentially connected to the top of the mounting base along the feeding direction. A connecting ring is provided on the top of the mounting base, and the connecting ring can slide horizontally along the width direction of the mounting base. A gear ring is rotatably connected inside the connecting ring, and multiple transmission gears with equally spaced points in a circular array centered on the center of the connecting ring are rotatably connected inside the connecting ring. The transmission gears mesh with the gear ring, and a driven rack is meshed on the transmission gear. One end of the driven rack is connected to a limit clamping ring, and an elastic binding band is connected between every two limit clamping rings. A mounting motor that drives one of the transmission gears to rotate is connected to one side of the connecting ring. When the gear ring rotates, it can cause the transmission gear to drive the driven rack to slide closer to or away from the center of the connecting ring. A drive assembly for driving the connecting ring to slide horizontally is provided inside the mounting base.

[0008] Furthermore, the drive assembly includes a reciprocating lead screw rotatably connected to the top of the mounting base, a transmission nut connected to the bottom of the connecting ring, the transmission nut being threaded onto the reciprocating lead screw, and a servo motor for driving the reciprocating lead screw to rotate connected to one side of the mounting base.

[0009] Furthermore, a guide rod is connected inside the mounting base, and the transmission nut is slidably connected to the guide rod. The transmission nut has a sliding opening that matches the guide rod.

[0010] Furthermore, the winding frame includes a fixed plate connected to the top of the mounting base, a turntable rotatably connected to the fixed plate, the turntable having multiple mounting holes, and a drive motor for driving the turntable to rotate connected to one side of the fixed plate.

[0011] Furthermore, the plurality of mounting holes are distributed in a circular array with equal spacing around the center of the turntable, and the number of mounting holes is the same as that of the connecting shaft.

[0012] Furthermore, the connecting ring has a connecting port adapted to the driven rack, and the connecting port is rectangular in shape.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Install the motor and start it, driving the connected transmission gear to rotate. This transmission gear meshes with the gear ring, causing the gear ring to rotate. Since multiple transmission gears mesh with the gear ring, the rotation of the gear ring synchronously drives the transmission gears to rotate. The transmission gear drives the driven rack meshing with it to slide towards or away from the center of the connecting ring, thereby moving the limiting clamping ring. The elastic restraint band connecting every two limiting clamping rings stretches or contracts accordingly, adjusting to the required size of the threading hole. This setting allows for adjustment of the threading hole size as needed, improving the twisting adaptation range.

[0015] 2. The servo motor drives the reciprocating lead screw to rotate, and the transmission nut connects to the connecting ring, causing the connecting ring to slide in the width direction of the mounting base, so that the twisted yarn can be evenly wound on the winding roller. This setting makes it easy to make the yarn evenly wound on the winding roller. Attached Figure Description

[0021] 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.

[0022] Please see Figure 1-4This utility model provides a technical solution: a glass fiber yarn twisting device, including a mounting base 1 and a connecting shaft 2, a winding frame 15, and a winding roller 3 sequentially connected to the top of the mounting base 1 along the feeding direction. A connecting ring 4 is provided on the top of the mounting base 1. The connecting ring 4 can slide horizontally along the width direction of the mounting base 1. A gear ring 5 is rotatably connected inside the connecting ring 4. Multiple transmission gears 6 are rotatably connected inside the connecting ring 4, with points evenly distributed in a circular array centered on the center of the connecting ring 4. The transmission gears 6 mesh with the gear ring 5. A driven rack 7 is meshed on the transmission gear 6. One end of the driven rack 7 is connected to a limiting clamping ring 8. An elastic binding band 9 is connected between every two limiting clamping rings 8. A mounting motor 14 is connected to one side of the connecting ring 4 to drive one of the transmission gears 6 to rotate. When the gear ring 5 rotates, the transmission gear 6 can drive the driven rack 7 to slide closer to or away from the center of the connecting ring 4. A driving assembly for driving the connecting ring 4 to slide horizontally is provided inside the mounting base 1.

[0023] In practice, the motor 14 drives one of the transmission gears 6 to rotate. The transmission gear 6 meshes with the gear ring 5, causing the gear ring 5 to rotate. Since multiple transmission gears 6 mesh with the gear ring 5, the rotation of the gear ring 5 synchronously drives the transmission gears 6 to rotate, thereby causing the driven rack 7 to slide towards or away from the center of the connecting ring 4, thus moving the limiting clamping ring 8. The elastic restraint band 9 connects the adjacent limiting clamping rings 8. When the limiting clamping ring 8 moves, the elastic restraint band 9 stretches or contracts, thereby adjusting the perforation size.

[0024] See Figure 1-4 The drive assembly includes a reciprocating screw 10 rotatably connected to the top of the mounting base 1, a transmission nut 11 connected to the bottom of the connecting ring 4, the transmission nut 11 being threaded onto the reciprocating screw 10, and a servo motor 12 for driving the reciprocating screw 10 to rotate connected to one side of the mounting base 1.

[0025] In practice, the servo motor 12 drives the reciprocating lead screw 10 to rotate, and the transmission nut 11, which is threadedly connected to the reciprocating lead screw 10, moves horizontally along the lead screw axis when the lead screw rotates. The transmission nut 11 is connected to the connecting ring 4, thereby causing the connecting ring 4 to slide horizontally in the width direction of the mounting base 1. This setting facilitates the collection of the twisted yarn and makes it evenly wound on the winding roller 3.

[0026] See Figure 1-4 The mounting base 1 is connected to a guide rod 13, and the transmission nut 11 is slidably connected to the guide rod 13. The transmission nut 11 has a sliding opening that matches the guide rod 13.

[0027] In practice, the guide rod 13 can limit the movement of the transmission nut 11, preventing it from rotating during operation and improving the stability of the transmission nut 11 during use.

[0028] See Figure 1-4 The winding bracket 15 includes a fixed plate connected to the top of the mounting base 1. A turntable is rotatably connected to the fixed plate. The turntable has multiple mounting holes. A drive motor for driving the turntable to rotate is connected to one side of the fixed plate.

[0029] In practice, during the twisting process, the yarn wound on the connecting shaft 2 can pass through the mounting holes opened on the turntable. Then, the drive motor drives the turntable to rotate, and the turntable drives the mounting holes to rotate, thus twisting the yarn.

[0030] See Figure 1-4 Multiple mounting holes are arranged in a circular array with equal spacing around the center of the turntable, and the number of mounting holes is the same as that of the connecting shaft 2.

[0031] In practice, multiple mounting holes are connected to the rotating shaft 2, which can simultaneously splice multiple strands of yarn after they have been twisted together, thus expanding the adaptability of the device.

[0032] See Figure 1-4 The connecting ring 4 has a connecting port that is adapted to the driven rack 7, and the shape of the connecting port is rectangular.

[0033] In practice, the connection port ensures that the driven rack 7 can move towards or away from the center of the connecting ring 4 under the drive of the transmission gear 6, and at the same time, it plays a certain limiting role for the driven rack 7 to prevent it from deviating during the movement.

[0034] Working principle: Starting from the feed end, the glass fiber yarn is first wound onto the connecting shaft 2, and then passes through the mounting holes on the winding frame 15 turntable.

[0035] Then, the motor 14 is started, driving the connected transmission gear 6 to rotate. This transmission gear 6 meshes with the gear ring 5, causing the gear ring 5 to rotate. Since multiple transmission gears 6 mesh with the gear ring 5, the rotation of the gear ring 5 synchronously drives the transmission gears 6 to rotate. The transmission gear 6 drives the driven rack 7, which meshes with it, to slide towards or away from the center of the connecting ring 4, thereby moving the limiting clamping ring 8. The elastic restraint band 9 connecting every two limiting clamping rings 8 stretches or contracts accordingly, adjusting to the required size of the threading hole.

[0036] Servo motor 12 drives reciprocating screw 10 to rotate, and transmission nut 11 connects to connecting ring 4, causing connecting ring 4 to slide in the width direction of mounting base 1, so that the twisted yarn can be evenly wound on winding roller 3.
