Technical Field

[0001] The utility model relates to the technical field of metal wire transmission, in particular to a metal wire transmission tension adjustment device. Background Art

[0002] Metal wire is a thin wire made of metal. When the metal wire needs to be transmitted and wound, a tension adjuster is generally used to ensure that the tension of the metal wire is the same during transmission and winding.

[0003] The servo tensioner with patent number CN205132744U is equipped with a wire-passing mechanism, a tension mechanism, a tension adjustment mechanism and a controller. The wire-passing mechanism includes a wire-passing guide wheel and a servo motor, and the servo motor is connected to the controller; the tension mechanism includes an angle sensor, a tension rod and a tension spring, and the angle sensor is connected to the controller. The lower end of the tension rod is connected to the angle sensor, and the upper end of the tension rod is provided with a wire outlet structure; the tension adjustment mechanism includes an electric adjustment mechanism and a cylinder adjustment mechanism. The electric adjustment mechanism can adjust the tension of the tension mechanism separately to realize segmented tension adjustment.

[0004] However, research has shown that existing tension adjusters still have the following defects:

[0005] The wire pay-off frame on the existing tension adjuster is fixedly connected to the rotating rod. Since the wire pay-off frame has a high working intensity, it is easy to be damaged. When replacing it, the rotating rod and the wire pay-off frame need to be replaced together, which is relatively wasteful. At the same time, the spring on the general tension adjuster is fixedly connected to a position of the rotating rod. When adjusting the tension, the spring needs to be replaced. When swinging, the spring is pulled by the electric push rod. However, the error of the electric push rod in pulling the spring is large, and it is difficult to adjust some subtle changes in tension. Therefore, it is necessary to optimize a metal wire transmission tension adjustment device through technological innovation and design optimization. Utility Model Content

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the present invention to clearly and completely describe the technical solution of the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. The instrument placement rack involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] This embodiment introduces a specific structure of a metal wire transmission tension adjustment device. Figures 1-3 As shown, a metal wire transmission tension adjustment device includes:

[0030] The tension adjuster body 3 has an electric push rod 4 installed on one side of the tension adjuster body 3. A rotating column 7 is passed through one side of the tension adjuster body 3. The rotating column 7 can rotate on the tension adjuster body 3. A rotating rod 2 is fixed on the rotating column 7. A spring 5 is provided between the rotating rod 2 and the output end of the electric push rod 4. A wire-releasing frame 1 is provided at the end of the rotating rod 2.

[0031] The limiting mechanism is located at the end of the rotating rod 2 and is used to limit the wire frame 1;

[0032] The adjusting mechanism is located on the rotating rod 2 and is used to adjust the position where the spring 5 is connected to the rotating rod 2.

[0033] The pay-off frame 1 on the tension adjuster commonly available in the market is fixedly connected to the rotating rod 2. Since the pay-off frame 1 has a high working intensity, it is relatively easy to be damaged. When replacing it, the rotating rod 2 and the pay-off frame 1 need to be replaced together, which is relatively wasteful.

[0034] The limiting mechanism includes a rotating groove 13 opened at the end of the rotating rod 2, and sliding grooves 17 are opened on both sides of the inner wall of the rotating groove 13. A rotating block 12 is provided in the rotating groove 13, and a rotating shaft 16 is passed through the rotating block 12. The rotating shaft 16 is fixedly connected to the rotating block 12, and the two ends of the rotating shaft 16 are respectively located inside the two sliding grooves 17. A threaded groove 15 is opened on the rotating rod 2, and a rotating ring 2 14 is provided on the rotating rod 2. The rotating shaft 16 can slide in the sliding groove 17, and the rotating ring 2 14 is threadedly connected to the threaded groove 15. A sliding hole 18 is opened on the wire frame 1, and the wire frame 1 is rotatably connected to the wire wheel 6 through the rotating shaft. The rotating rod 2 can pass through The sliding hole 18 is provided, and the wire-releasing frame 1 can slide on the rotating rod 2. A notch 19 is provided on the wire-releasing frame 1. Both ends of the rotating block 12 can be inserted into the notch 19, which is convenient for limiting the wire-releasing frame 1 and preventing the wire-releasing frame 1 from rotating on the rotating rod 2. The wire-releasing frame 1 is put onto the rotating rod 2, and the rotating block 12 is rotated so that the rotating block 12 is perpendicular to the rotating rod 2. When sliding the rotating block 12, one side of the rotating block 12 is close to the inside of the rotating groove 13, and the rotating ring 2 14 is rotated so that the rotating ring 2 14 is close to the wire-releasing frame 1. The rotating ring 2 14 cooperates with the rotating block 12 to limit the wire-releasing frame 1. The reverse operation can be performed to remove the wire-releasing frame 1, which is simple and convenient.

[0035] At the same time, the spring 5 on the general tension adjuster is fixedly connected to a position of the rotating rod 2. When adjusting the tension, the spring 5 needs to be replaced. When waving, the spring 5 is pulled by the electric push rod 4. However, the error of the electric push rod 4 in pulling the spring 5 is large, and it is difficult to adjust some subtle changes in tension.

[0036] The adjusting mechanism includes two fixed plates 8 fixed on the rotating rod 2, a screw rod 10 is fixed between the two fixed plates 8, the rotating rod 2 is provided with a sliding block 9 between the two fixed plates 8, the rotating rod 2 passes through the sliding block 9, a circular hole is opened on the sliding block 9, the screw rod 10 passes through the circular hole, and the sliding block 9 can slide on the rotating rod 2 and the screw rod 10. The outside of the screw rod 10 is located on both sides of the sliding block 9 and is sleeved with a rotating ring 11. The two rotating rings 11 are threadedly connected to the screw rod 10 to facilitate the rotation of the rotating ring 11. One end of the spring 5 is fixedly connected to the output end of the electric push rod 4, and the other end of the spring 5 is fixedly connected to the sliding block 9. By rotating the two rotating rings 11, the two rotating rings 11 can drive the sliding block 9 to slide on the screw rod 10 and the rotating rod 2, thereby completing the adjustment of the position of the sliding block 9, thereby finely adjusting the tension of the spring 5 and reducing the error during tension adjustment.

[0037] When the staff needs to disassemble and assemble the wire-laying frame 1, put the wire-laying frame 1 onto the rotating rod 2, rotate the rotating block 12 so that the rotating block 12 is perpendicular to the rotating rod 2, slide the rotating block 12 so that one side of the rotating block 12 is close to the inside of the rotating groove 13, rotate the rotating ring 2 14 so that the rotating ring 2 14 is close to the wire-laying frame 1, and the rotating ring 2 14 cooperates with the rotating block 12 to limit the wire-laying frame 1. The reverse operation can be performed to remove the wire-laying frame 1, which is simple and convenient.

[0038] When fine adjustment of the tension is required, by rotating the two rotating rings 11 in the same direction, the two rotating rings 11 can drive the sliding block 9 to slide on the screw rod 10 and the rotating rod 2, thereby completing the adjustment of the position of the sliding block 9, thereby finely adjusting the tension of the spring 5 and reducing the error during tension adjustment.
