Description

Technical Field

[0001] This utility model belongs to the field of glass fiber production technology, and specifically relates to a glass fiber drawing device. Background Technology

[0002] The glass fiber production process includes steps such as raw material mixing, melting, drawing, and coating. First, the glass raw materials are mixed and melted at high temperature, then drawn into extremely fine fibers through micropores. Subsequently, a coating process is applied to enhance performance, and finally, various products are manufactured according to requirements.

[0003] During the production of glass fiber, the drawn glass fiber needs to be wound and stored. However, existing drawing equipment typically requires stopping the machine after a roll is fully wound with glass fiber, removing the roll, and then installing a new roll, which is time-consuming, labor-intensive, and inefficient. Therefore, a new type of glass fiber drawing equipment is needed. Utility Model Content

[0004] To address the aforementioned problems, this utility model discloses a glass fiber drawing device.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A glass fiber drawing device includes a mounting plate consisting of a bottom plate and side plates perpendicular to each other. The side plates of the mounting plate have V-shaped grooves. Electric telescopic rods with free ends inclined downwards and extending in the same direction as the V-shaped grooves are installed on both sides of the grooves. A slider is fixedly connected to the free end of each electric telescopic rod, and each slider is slidably installed in the V-shaped groove. Each slider is rotatably connected to a horizontally arranged clamping assembly adapted to clamp a roll. A second friction wheel is coaxially fixedly sleeved on each clamping assembly. A drive motor is installed directly below the bend of the V-shaped groove, and the output end of the drive motor is coaxially fixedly connected to a first friction wheel adapted to the second friction wheel. A guide assembly parallel to the roll is installed on the top of the side plates of the mounting plate.

[0007] As a preferred technical solution of this utility model, each clamping assembly includes a clamping cylinder rotatably connected to the slider. The clamping cylinder is provided with a number of straight grooves parallel to its own axis. A clamping strip is slidably installed in each straight groove, and the clamping strip and the clamping cylinder are elastically connected by a number of springs. The drum shaft is provided with a through hole adapted to the insertion of the clamping cylinder and the clamping strip.

[0008] In a preferred embodiment of this invention, the clamping cylinder and the slider are rotatably connected by a bearing.

[0009] As a preferred embodiment of this utility model, both the clamping cylinder and the clamping bar are provided with rounded corners adapted to be inserted into the drum.

[0010] As a preferred technical solution of this utility model, the guide assembly includes a plug-in seat fixedly connected to the side plate of the mounting plate, a guide strip is inserted into the plug-in seat laterally, the guide strip has several linearly evenly distributed notches with upward openings, and a rotating wheel is installed in each notch, the plug-in seat is vertically inserted with a pin, and the pin is simultaneously inserted into the guide strip; the drum is provided with several annular grooves of a number adapted to the guide strip.

[0011] As a preferred embodiment of this utility model, the rotating wheel is provided with an annular groove coaxial with the rotation axis.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This application is equipped with an alternating drive clamping assembly, and the clamping assembly and the roll are quick-release fixed, so that when one roll is fully wound with glass fiber bundle, it quickly disengages from the drive of the first friction wheel for easy removal, while the other empty roll is quickly braked to the position driven by the first friction wheel to wind the glass fiber bundle, thereby reducing the downtime of the glass fiber drawing equipment due to roll replacement and improving production efficiency.

[0014] Second, the annular grooves of the roll in this application correspond one-to-one with the rotating wheels, which isolates and stores the glass fiber bundles, reduces the entanglement between the glass fiber bundles, and facilitates the direct use of the glass fiber bundles for weaving production in the future.

[0025] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0026] Please see Figure 1-5 A glass fiber drawing device includes a mounting plate 1, which is composed of a bottom plate and side plates perpendicular to each other. Through holes for mounting and fixing are provided at the corners of the mounting plate 1. V-shaped grooves are formed on the side plates of the mounting plate 1, and electric telescopic rods 4 with their free ends inclined downwards are installed on both sides of the V-shaped grooves, extending in the same direction as the grooves. A slider 5 is fixedly connected to the free end of each electric telescopic rod 4, and each slider 5 is slidably installed in the V-shaped groove. Each slider 5 is rotatably connected to a horizontally arranged clamping assembly 8, which is adapted to clamp a roll 10. A second friction wheel 7 is coaxially fixedly sleeved on each clamping assembly 8. A drive motor 2 is installed directly below the bend of the V-shaped groove, and the output end of the drive motor 2 is coaxially fixedly connected to a first friction wheel 3 adapted to the second friction wheel 7. The diameter of the first friction wheel 3 is smaller than that of the second friction wheel 7, so as to drive the roll 10 to rotate at a low speed to wind the glass fiber. Both the first friction wheel 3 and the second friction wheel 7 are rubber wheels, and they can transmit power through friction. The top of the side plate of the mounting plate 1 is equipped with a guide assembly 9 that is parallel to the drum 10.

[0027] Each clamping assembly 8 includes a clamping cylinder 801 rotatably connected to the slider 5. The clamping cylinder 801 and the slider 5 are rotatably connected via a bearing 6. The clamping cylinder 801 is provided with several straight grooves parallel to its own axis, and a clamping strip 803 is slidably installed in each straight groove. The clamping strip 803 is elastically connected to the clamping cylinder 801 via several springs 802. The drum 10 has a through hole on its shaft to accommodate the insertion of the clamping cylinder 801 and the clamping strip 803. After the drum 10 is inserted into the clamping cylinder 801, the clamping strip 803 partially retracts towards the axis of the clamping cylinder 801 (the clamping strip 803 always extends out of the straight groove), and the retracted clamping strip 803 presses against the inner wall of the drum 10 under the elastic force of the springs 802.

[0028] Both the clamping cylinder 801 and the clamping bar 803 are provided with rounded corners to accommodate the insertion of the drum 10, so that the through hole of the drum 10 can be coaxially inserted into the clamping cylinder 801.

[0029] The guide assembly 9 includes a connector 901 fixedly connected to the side plate of the mounting plate 1, with a guide strip 902 horizontally inserted into the connector 901. The guide strip 902 has several linearly evenly distributed, upward-facing notches, and a rotating wheel 903 is installed in each notch. A pin 904 is vertically inserted into the connector 901, and the pin 904 is simultaneously inserted into the guide strip 902. The drum 10 has several annular grooves, the number of which matches the guide strip 902. A bundle of glass fibers, composed of several glass fibers, enters the annular grooves of the same drum 10 after being guided by the same rotating wheel 903, facilitating the isolated storage of the glass fiber bundles.

[0030] The rotating wheel 903 is provided with an annular groove coaxial with the rotation axis. The annular groove of the rotating wheel 903 is used to constrain the guided glass fiber bundle. The top of the pin 904 is provided with a ring for easy lifting. The number and size of the rotating wheels 903 are determined by the glass fiber bundles produced, and the annular grooves of the spool 10 correspond one-to-one with the rotating wheels 903.

[0031] Working principle:

[0032] During production, coaxial drums 10 are inserted into the clamping assemblies 8 on both sides. Then, the electric telescopic rod 4 on one side pushes the slider 5 to the turning point of the V-shaped groove, causing the first friction wheel 3 and the second friction wheel 7 to come into frictional contact. Then, the drive motor 2 drives the second friction wheel 7 to rotate through the first friction wheel 3, causing the second friction wheel 7 to drive the clamping assembly 8 and the drum 10 to rotate together. Then, the glass fiber bundle pulled by the guide assembly 9 is wound into the annular groove of the drum 10. When the drum 10 is fully wound with the glass fiber bundle, the drive motor 2 briefly stops to cut the glass fiber bundle. Then, the electric telescopic rod 4 retracts to move the drum 10 fully wound with the glass fiber bundle away from the first friction wheel 3, making it easier to remove the drum 10 fully wound with the glass fiber bundle. At the same time, the electric telescopic rod 4 on the other side pushes the slider 5 to the turning point of the V-shaped groove, causing another drum 10 to wind the glass fiber bundle. In this way, the two sides alternate to minimize the downtime of the drawing equipment caused by installing and removing the drum 10.

[0033] It should be noted that the above content merely illustrates the technical concept of this utility model and cannot be used to limit the scope of protection of this utility model. For those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and all such improvements and modifications fall within the scope of protection of the claims of this utility model.
