[0019] The technical solution of the present invention will be further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0020] Embodiment: A tensioning device for a filament winding machine, such as Figure 1-Figure 5 As shown, it includes a frame 1, a plurality of mounting plates 61 are provided on one side of the top of the frame 1, and a forward-bent discharge roller 62 is provided on the top of each mounting plate 61. A middle partition 11 is provided in the middle of the frame 1, and the middle partition 11 separates the interior of the frame 1 into two upper and lower cavities. A plurality of glass fiber materials 2 are provided in the two cavities, and a material tray 14 is provided at the bottom of each glass fiber material 2. A rotating shaft 141 is provided downwardly through the middle of the top of each material tray 14. When the glass fiber material 2 is yarned, the material tray 14 is provided at the bottom to facilitate the rotation of the glass fiber material 2, so that the feeding effect is better. A plurality of yarn guide mechanisms 12 are provided on the top of the two cavities, and a single yarn guide mechanism 12 is provided corresponding to the top setting of a single glass fiber material 2. The glass fiber materials 2 in the cavity are divided into two groups. A sensor 13 is provided in the middle position of the two groups of glass fiber materials 2 corresponding to each glass fiber material 2. The sensor 13 adopts a diffuse reflection sensor 13. A feeding mechanism 5 is provided on the top of each glass fiber material 2. The feeding mechanism 5 located in the top cavity is set on the frame 1, and the feeding mechanism 5 located in the bottom cavity is set at the bottom of the middle partition 11. Glass fiber material 2 is installed inside each feeding mechanism 5. A tension mechanism 3 is provided on the right side of the frame 1. Multiple side frames 31 are provided on the front and back sides of the tension mechanism 3. The tension mechanism 3 is connected to the frame 1 through the side frames 31. A discharging rack 4 is inserted in the right side of the frame 1, and multiple discharging rollers 41 corresponding to the cavity are provided on the top right side of the discharging rack 4.

[0021] The feeding mechanism 5 includes a mounting plate 51, an electric telescopic rod 52, a jacket 53, a positioning pin 54, an articulated arm 55, a material pressing frame 56, a rubber sleeve 562, a fixing rod 57, a mounting frame 58, an auxiliary material roller 59 and a positioning rod 510. The glass fiber material 2 for feeding is placed inside the feeding mechanism 5. The mounting plate 51 is correspondingly arranged on the front side of the frame 1. The electric telescopic rod 52 is arranged on the mounting plate 51, and the output end is arranged toward the inside of the frame 1. The jacket 53 is arranged on the output end of the electric telescopic rod 52. The connection between the jacket 53 and the electric telescopic rod 52 is connected by a positioning pin 54. The articulated arms 55 are respectively arranged on both sides of the jacket 53, and the connection is rotatably connected to each other. The sleeve 53 is correspondingly arranged above the glass fiber material 2, and the pressing frames 56 are respectively correspondingly arranged at the top and bottom on the left and right sides of the glass fiber material 2. The two hinged arms 55 are connected to each other in rotation at one end away from the jacket 53 and the side of the pressing frame 56 corresponding to the same side. A slide groove 561 is provided at both ends of each pressing frame 56. The fixing rod 57 passes through the slide groove 561 and is inserted into the pressing frame 56, and the fixing rod 57 passes through and is arranged between the two pressing frames 56. The rubber sleeve 562 is set at the top and bottom of the connection between the fixing rod 57 and the pressing frame 56. The top of the fixing rod 57 is fixedly installed on the top of the inner wall of the frame 1, and the positioning rod 510 is inserted on the left and right sides of the two upper and lower pressing frames 56.

[0022] The mounting frame 58 is set in the middle of the fixed rod 57, and the auxiliary material roller 59 is set between the mounting frames 58 on the two fixed rods 57 on the same side, and the auxiliary material roller 59 extends outward away from the glass fiber material 2. The setting of the auxiliary material roller 59 is used to prevent the bottom glass fiber material 2 from being affected by the feeding mechanism 5 when the yarn is being put on, thereby preventing the yarn from breaking.

[0023] A base 71 is provided on one side of the mounting plate 51, and a plurality of discharge troughs 72 are provided on the base 71. A positioning block 73 is provided on the top of the base 71, and a pressing block 74 is provided at the bottom of the positioning block 73 corresponding to the discharge trough 72. A plurality of discharge troughs 72 for placing the ends of the glass fiber material 2 are provided on the base 71, and a positioning block 73 corresponding to the discharge trough 72 is provided on the positioning block 73, so that the pulled-out ends can be clamped. After the auxiliary glass fiber material 2 is unloaded, the ends can be quickly picked out, which is convenient for workers to take out the ends for quick installation.

[0024] The principle of the present invention is as follows: when one of the glass fiber materials 2 in the frame 1 is used up, the sensor 13 on one side does not sense the yarn, and transmits a signal to the central control device. The central control device sends a signal to the electric telescopic rod 52, and the electric telescopic rod 52 opens and extends upward, driving the jacket 53 and the articulated arms 55 on both sides to move backward, thereby driving the press frames 56 connected to the outside of the two articulated arms 55 to push to both sides. Since the top press frame 56 and the bottom press frame 56 are synchronously limited by the positioning rod 510, when the top press frame 5 6 is pushed outward, the bottom pressing frame 56 will also open outward, and the top pressing frame 56 and the bottom pressing frame 56 are simultaneously limited by the fixed rod 57 fixed on the frame 1, so that the spare glass fiber material 2 located between the top pressing frame 56 and the bottom pressing frame 56 on both sides loses the clamping and falls downward to the material tray 14 at the bottom. Since the thread end of the auxiliary glass fiber material 2 is clamped between the base 71 and the positioning block 73 in advance, the worker can quickly identify the position of the thread end after it falls, which is convenient for the worker to operate quickly.

[0025] The worker sends the thread end of the auxiliary glass fiber material 2 backward through the top yarn guide mechanism 12 to the right to the tension mechanism 3, and then sends it to the next process through the discharge roller 41. At the same time, the auxiliary glass fiber material 2 is lost in the feeding mechanism 5 at the top. Then the worker takes out the glass fiber material 2 set on the top discharge roller 62 and sends the glass fiber material 2 into the feeding mechanism 5 to facilitate the next loading.

[0026] Finally, it should be noted that the above embodiments are merely representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments and is susceptible to numerous variations. Any simple modifications, equivalent variations, and modifications to the above embodiments based on the technical essence of the present invention are deemed to fall within the scope of protection of the present invention.
