Description

Technical Field

[0001] This utility model relates to the field of flame-retardant polypropylene filament production technology, specifically a flame-retardant polypropylene filament winding device. Background Technology

[0002] In the production of flame-retardant polypropylene filament, the winding device is a crucial component. Traditional winding devices often suffer from problems such as complex structure, inconvenient operation, low winding efficiency, and easy breakage of the filaments during winding. Especially when processing special materials like flame-retardant polypropylene filament, due to the material's inherent characteristics, such as reduced flammability but potentially increased brittleness, the requirements for the winding device are even more stringent. Traditional winding devices struggle to meet the demands for efficient, stable, and safe winding, easily leading to low production efficiency and inconsistent product quality.

[0003] Therefore, developing a high-efficiency winding device specifically for flame-retardant polypropylene filaments has become key to improving production efficiency and product quality. Utility Model Content

[0004] The purpose of this invention is to provide a flame-retardant polypropylene filament winding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flame-retardant polypropylene filament winding device, comprising a bottom fixing plate, a working box at the bottom of the bottom fixing plate, a rotating shaft at the center of the top of the bottom fixing plate, a winding cylinder at the top of the bottom fixing plate, a connecting hole through the center of the winding cylinder, the connecting hole being inserted into the rotating shaft, a support column fixedly connected to the top of the bottom fixing plate on one side of the winding cylinder, a stepper linear motor movably mounted on the side wall of one end of the support column, a wire block fixedly connected to the end of the stepper linear motor away from the support column, and a wire hole through the side wall of the wire block near the end of the winding cylinder.

[0006] As a further embodiment of this utility model: a seated bearing is fixedly connected to the bottom of the rotating shaft, and the seated bearing is embedded and fixedly connected to the center position of the bottom fixed plate.

[0007] As a further improvement of this utility model: the inner wall of the working box is provided with an internal working cavity, and a rotary motor is fixedly connected to the inner wall of the internal working cavity.

[0008] As a further embodiment of this utility model: the output end of the rotary motor is oriented towards the bottom, and a drive shaft is fixedly connected to the output end of the rotary motor.

[0009] As a further embodiment of this utility model: a through bearing is fixedly connected to the outer wall of the top end of the drive shaft, the drive shaft is rotatably connected to the top of the work box through the through bearing, and the top of the drive shaft is fixedly connected to the bottom of the rotating shaft.

[0010] As a further improvement of this utility model: the bottom outer wall of the work box is fixedly connected with a fixing ear, and the top of the fixing ear is evenly fixedly connected with multiple fixing bolts.

[0011] Compared with existing technologies, the advantages of this invention are as follows: In this invention, a rotating shaft is driven by a rotary motor, which in turn drives the winding drum to rotate rapidly, achieving efficient winding of polypropylene filaments and significantly improving production efficiency. The rotating shaft is securely connected to the bottom fixed plate via a bearing with a mounting seat, ensuring stability during the winding process and reducing the risk of filament breakage.

[0012] A stepper linear motor drives the lead block to move linearly, precisely guiding the polypropylene filament through the lead hole, ensuring the neatness and tightness of the winding. The device has a simple structure and is easy to operate, reducing the difficulty and labor intensity for workers and improving production safety and comfort. This device is not only suitable for winding flame-retardant polypropylene filament, but its parameters can also be adjusted as needed to adapt to the winding requirements of filaments of different specifications and materials.

Therefore, they should not be construed as limitations on this utility model.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0019] like Figures 1 to 5 As shown, a flame-retardant polypropylene filament winding device includes a bottom fixing plate 1, with a work box 2 at its bottom. The work box 2 is securely installed on the worktable by fixing ears 3 and fixing bolts 12.

[0020] A rotating shaft 5 is provided at the center of the top of the bottom fixed plate 1. The bottom of the rotating shaft 5 is embedded and fixedly connected to the center of the bottom fixed plate 1 through a bearing 11 to ensure the stability of rotation.

[0021] A winding cylinder 6 is inserted into the rotating shaft 5. The winding cylinder 6 is used to wind flame-retardant polypropylene filaments.

[0022] A support column 4 is fixedly connected to the top of the bottom fixing plate 1 located on one side of the winding cylinder 6. A stepper linear motor 8 is movably installed on the side wall of one end of the support column 4. A wire block 9 is fixedly connected to the end of the stepper linear motor 8 away from the support column 4. A wire hole 10 is opened through the side wall of the wire block 9 near the end of the winding cylinder 6 to guide the winding path of the polypropylene filament.

[0023] The inner wall of the working box 2 has an internal working cavity 15. A rotary motor 16 is fixedly connected to the inner wall of the internal working cavity 15. The output end of the rotary motor 16 is set facing the bottom and is fixedly connected to a drive shaft 14.

[0024] A through bearing 13 is fixedly connected to the top outer wall of the drive shaft 14. The through bearing 13 is rotatably connected to the top of the work box 2. The top of the drive shaft 14 is fixedly connected to the bottom of the rotating shaft 5, thereby realizing the drive of the rotating shaft 5 by the rotating motor 16. Example

[0025] In actual production applications, the rotation speed of the rotary motor 16 and the moving speed of the stepper linear motor 8 can be adjusted according to the specifications of the polypropylene filament and the winding requirements.

[0026] For example, for finer polypropylene filaments, the rotation speed of the rotary motor 16 can be appropriately reduced, while the moving speed of the stepper linear motor 8 can be slowed down to ensure the tightness and uniformity of the winding; while for thicker polypropylene filaments, the rotation speed and moving speed can be increased accordingly to improve production efficiency.

[0027] The working principle of this utility model is as follows: the winding cylinder 6 is inserted into the rotating shaft 5 to ensure a stable connection. One end of the flame-retardant polypropylene filament is passed through the wire hole 10 on the wire block 9 and fixed to the winding cylinder 6.

[0028] The rotary motor 16 is started, which drives the rotary shaft 5 to rotate via the drive shaft 14, thereby driving the winding drum 6 to rotate at high speed. At the same time, the stepper linear motor 8 is started, which drives the lead block 9 to move linearly back and forth, so that the polypropylene filament is wound evenly and neatly on the winding drum 6.

[0029] During the winding process, the rotational speed of the rotary motor 16 and the moving speed of the stepper linear motor 8 can be adjusted according to the actual situation to adapt to the winding requirements of polypropylene filaments of different specifications and materials. At the same time, the winding process is closely monitored to ensure winding stability and product quality.

[0030] When the winding reaches the predetermined length or weight, turn off the rotary motor 16 and the stepper linear motor 8, remove the wound winding cylinder 6, and complete one winding process.
