Problems solved by technology

This scheme has a complex structure, is equipped with a motor, and consumes electric energy, and because the speed of the variable frequency motor is controlled by the feedback device after the yarn tension changes, the system lags a lot, and the tension is actually in a small real-time change state.
The above-mentioned devices are all used for tension control of thinner and softer wires. Since winding cables such as transformers and reactors are much thicker and relatively hard, the above-mentioned pay-off devices are not suitable for conductive cables such as transformers and reactors. Constant tension pay-off not applicable

Embodiment 1

[0037] like Figure 1 to Figure 3 As shown, a constant tension pay-off frame of the present invention includes a bobbin 2 arranged on a frame 1, a bobbin 3 is installed on one side of the bobbin 2, and when the bobbin 2 rotates, the bobbin 3 is The bobbin 2 drives synchronous rotation. The other side of bobbin 2 is installed brake 8.

[0038] A pressure roller shaft 6 is also arranged on the frame 1, a pressure roller arm group 5 and a pressure roller handle 13 are installed on one side of the pressure roller shaft 6, and an angle sensor 7 is installed on the other side. The pressure roller shaft 6 is a round shaft, one end of the first pressure roller arm 51 and the second pressure roller arm 52 is sleeved on the pressure roller shaft 6, and the connection between the first pressure roller arm 51 and the second pressure roller arm 52 and the pressure roller shaft is set There is a screw hole matching with the top wire 12, and a positioning groove for matching the top wire i...

Embodiment 2

[0046] The difference between this preferred embodiment and the first preferred embodiment is that this preferred embodiment also includes an alignment roller set 10 .

[0047] like Figure 1 to Figure 3As shown, the group of alignment rollers 10 includes a roller support plate 101 , a roller angle iron 102 , a roller support plate 103 and a roller shaft 104 . The roller set 10 is located on the side of the bobbin 3 away from the pressure roller shaft and not lower than the upper top surface of the bobbin when the winding is at its maximum winding. The roller support plate 101 is a rectangular iron plate, which is fixedly connected with the upper corner of the frame 1 . The roller shaft angle iron 102 is fixedly connected to the roller shaft support plate 101 at 90 degrees, and is parallel to the ground. One end of the roller angle iron 102 is connected to the roller support plate 101 , and the other end is fixedly connected to the roller support plate 103 . A roller shaft ...

Embodiment 3

[0050] The difference between this preferred embodiment and preferred embodiment 1 or preferred embodiment 2 is that the frame 1 can be welded by square steel, channel steel, angle iron or their combination, and can also be other detachable installations. The positions of the bobbin 2 and the roller shaft 6 on the frame 1 are not limited, and the quantity is not limited. The installation position of the angle sensor 7 is not limited, as long as it can receive the angle change signal when the pressure roller arm group 5 rotates. The installation position of the controller 9 is not limited, as long as it can receive the signal output by the angle sensor 7 and can transmit the output signal of the controller 9 to the brake 8 . The installation position of the brake 8 is not limited, as long as it can receive the output signal of the controller 9 and control the torque of the winding shaft 2 . The installation position of the pressure roller handle 13 is not limited, as long as i...

Abstract

The invention discloses a constant-tension pay-off rack, and relates to the field of cable production equipment. The constant-tension pay-off rack comprises a machine frame, a winding shaft, a winding reel pressing roller, a pressing roller arm set, a pressing roller shaft, an angle sensor, a brake and a controller, wherein the winding shaft is installed on the machine frame and is provided with the brake, a winding reel is fixedly connected with the winding shaft, the pressing roller shaft is installed on the machine frame, the pressing roller shaft is provided with the angle sensor, one end of the pressing roller arm set is connected with the pressing roller shaft, the other end of the pressing roller arm set is connected with the pressing roller, the pressing roller is pressed above a wire winding portion on the winding reel, the signal output end of the angle sensor is connected with the signal input end of the controller, and the signal output end of the controller is connected with the signal input end of the brake. The constant-tension pay-off rack is simple in structure, low in manufacturing cost, needless of a motor, environmentally friendly, convenient to operate, and capable of controlling pay-off tension constancy.

Description

technical field [0001] The invention relates to a pay-off frame, in particular to a constant tension pay-off frame. Background technique [0002] In the wire and cable industry, transformer and textile industry, pay-off racks are required. None of the existing pay-off racks can maintain a stable tension, often tightening and loosening suddenly, causing unstable factors to product quality. Chinese Patent Document No. CN201773697U discloses a coil pay-off frame, which is provided with a brake next to the wire reel. The wire reel is provided with a cylinder and a wire passing wheel matched with the wire reel. The brake connected to the precision regulating valve is controlled according to different Wire gauges provide different constant tensions. Because its tension is affected by the dual action of the brake and the cylinder of the wire passing wheel, and the pressure generated by the cylinder is different with different degrees of expansion and contraction (if the air press...
