DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0024] Please refer to Figures 1-6 In the embodiments of the utility model, a high-speed stranding machine tension pay-off device comprises:

[0025] The support 100, the fixing mechanism 200 capable of positioning the position of the wire reel, the U-shaped frame 300 and the adjusting mechanism 400 capable of adjusting the pay-off tension, the support 100 is fixedly connected with the connecting plate 110, the fixing mechanism 200 is fixedly sleeved with the connecting plate 110, the U-shaped frame 300 is fixedly connected to the top end of the support 100, the connecting box 320 is fixedly connected between the two opposite inner side walls of the U-shaped frame 300, and the connecting box 320 is internally provided with a tension detector capable of detecting the pay-off tension, the adjusting mechanism 400 is located below the U-shaped frame 300, the adjusting mechanism 400 comprises two round plates 410, a sliding groove is formed in the center of one side of each of the two round plates 410, two slide rods 420 are arranged between the two round plates 410, the two ends of each slide rod 420 are slidably connected to the interiors of the two sliding grooves respectively, two protrusions are fixedly connected to one side of each round plate 410, a bidirectional screw 430 is rotatably connected between the two protrusions on one side of each round plate 410, an internally threaded ring is fixedly connected to the two ends of each slide rod 420, and the two internally threaded rings on each slide rod 420 are respectively screwed with the two bidirectional screws 430.

[0026] Specifically, by connecting the reel to the fixing mechanism 200, the line on the reel is then sequentially passed around the two slide bars 420, as follows: Figure 5 As shown, the wire passes through the center of the two circular plates 410, and the parts of the two sliding rods 420 that contact the wire are arranged diagonally around the circular plates 410. The connecting box 320 has a wire-passing hole. The wire is then passed through the wire-passing hole and then through the traction device to connect to the stranding machine. The two circular plates 410 are rotated, and the two sliding rods 420 are used to control the tension of the wire entering the stranding machine. The tension of the wire entering the stranding machine can be detected by a tension detector. When the wire is being released normally from the reel, the distribution of the wire on the two sliding rods 420 is as shown. Figure 6 As shown, due to the friction between the wire and the slide bar 420, the traction force of the traction device is adjusted to ensure the wire is released normally with appropriate tension. When the wire tension is too low, the two circular plates 410 can be rotated to increase the number of strands of wire on the slide bar 420, making it less likely for the cable to slip on the slide bar 420. When the wire tension is too high, the two circular plates 410 can be rotated in the opposite direction to reduce the contact area between the wire and the slide bar 420, thus facilitating wire movement. This allows for a larger adjustment range, which is useful in situations such as temporary shutdown of the traction device or adjustment of the traction force. When the wire tension is too low and becomes loose, the wire can be temporarily stored by rotating the two circular plates 410 and winding it around the two slide bars 420. After the traction equipment is adjusted and the traction force is normal, the temporarily wound wire can be released by rotating the circular plates 410 in the opposite direction, thereby reducing the situation where the wire drags on the ground when adjusting the traction force. The bidirectional screw 430 is a screw with both positive and negative threads. When rotated, it can drive the two slide bars 420 to move towards or away from each other, thereby making it convenient for the user to adjust the distance between the two slide bars 420.

[0027] Example 1

[0028] like Figures 1-2 As shown, in this embodiment, two connecting rings are fixedly connected to one side of the bracket 100, and a rotating rod 440 is rotatably sleeved inside each of the two connecting rings. A U-shaped plate 411 is fixedly connected to the center of one side of each of the two circular plates 410, and one end of each of the two rotating rods 440 is fixedly connected to one side of the two U-shaped plates 411 respectively. A motor box 130 is fixedly connected to the bracket 100, and a stepper motor is installed inside the motor box 130. The motor shaft of the stepper motor is fixedly connected to the other end of the adjacent rotating rod 440.

[0029] In this embodiment, the stepper motor is equipped with an electromagnetic brake, which prevents the motor shaft from rotating when the stepper motor is not started. The stepper motor is controlled by a controller to start and stop, so that the stepper motor can drive the two circular plates 410 to rotate through the rotating rod 440, which is convenient for the user.

[0030] like Figure 1 and Figures 3-4As shown, in this embodiment, the fixing mechanism 200 includes:

[0031] The device includes a positioning screw 210 and a ball bearing 220 for placing the spool. The ball bearing 220 includes an inner ring and an outer ring. The inner ring is fixedly sleeved to one end of the positioning screw 210. A collar 111 is fixedly connected to one side of the connecting plate 110, and the outer ring is fixedly sleeved inside the collar 111. Two washers 211 are movably sleeved on the positioning screw 210. A slide rail 120 is fixedly connected to the top surface of the connecting plate 110, and the slide rail 120 is located above the positioning screw 210. A slider 121 is slidably engaged inside the slide rail 120, and a circular hole is opened at the top of the slider 121. A guide tube 122 is fixedly sleeved inside the circular hole on the slider 121, and both ends of the guide tube 122 are flared structures.

[0032] In practical implementation, when in use, the reel is inserted onto the positioning screw 210, and then two washers 211 are placed on opposite sides of the reel. Then, the nut is screwed onto the positioning screw 210 to prevent the reel from contacting the ball bearing 220 and the nut. The wire on the reel is then passed through the guide tube 122. When the wire on the reel is pulled, the reel can drive the positioning screw 210 to rotate synchronously by relying on the ball bearing 220. The position where the wire is pulled out from the reel is parallel to the two slide bars 420, which facilitates the movement of the wire. The flared structure at both ends of the guide tube 122 facilitates the guidance of the wire.

[0033] Example 2

[0034] Based on Embodiment 1, the guide wheel 310 and sleeve 421 are provided to facilitate the movement of the wire.

[0035] like Figure 2 and Figure 4 As shown, in this embodiment, two guide wheels 310 are rotatably connected between the opposite sides of the U-shaped frame 300, and the two guide wheels 310 are located on opposite sides of the connecting box 320, and sleeves 421 are rotatably sleeved on the outer walls of the two slide rods 420.

[0036] In practice, when the wire passes around the outer wall of the slide bar 420, it is fitted onto the sleeve 421, so that the wire can slide more smoothly under normal conditions by relying on the sleeve 421. When the wire passes through the wire hole, it should be supported by the two guide wheels 310, so that the wire can be supported flat by the two guide wheels 310 and pass through the wire hole more smoothly.

[0037] It is apparent for a person skilled in the art that the present application is not limited to the details of the above-described exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary and non-limiting, the scope of the present application being defined by the claims appended hereto rather than by the above description, and all the changes which fall within the meaning and the scope of the equivalent elements of the claims are intended to be embraced therein.
