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 the frame 1, and a bobbin 3 is installed on one side of the bobbin 2. When the bobbin 2 rotates, the bobbin 3 is The winding shaft 2 drives the synchronous rotation. A stopper 8 is installed on the other side of the spool 2 .

[0038] The frame 1 is also provided with a pressing roller shaft 6 , one side of the pressing roller shaft 6 is mounted with a pressing roller arm group 5 and a pressing roller handle 13 , and the other side is mounted with an angle sensor 7 . The pressing roller shaft 6 is a circular shaft, one end of the first pressing roller arm 51 and the second pressing roller arm 52 is sleeved on the pressing roller shaft 6, and the first pressing roller arm 51 and the second pressing roller arm 52 are connected with the pressing roller shaft. There is a screw hole matched with the top screw 12, the pressing roller shaft is provid...

Embodiment 2

[0046] The difference between this preferred embodiment and the first preferred embodiment is that this preferred embodiment further includes a set of alignment rollers 10 .

[0047] like Figure 1 to Figure 3As shown, the set 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 shaft group 10 is located on the side of the bobbin 3 away from the pressing roller shaft and is not lower than the upper top surface of the bobbin when the maximum winding is performed. The roller support plate 101 is a rectangular iron plate, which is fixedly connected to the upper corner of the frame 1 . The roller angle iron 102 is fixedly connected with the roller 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 104...

Embodiment 3

[0050] The difference between this preferred embodiment and the first or second preferred embodiment is that the frame 1 can be welded by square steel, channel steel, angle iron or a combination thereof, or can be detachably installed. The positions of the winding shaft 2 and the pressing roller shaft 6 on the frame 1 are not limited, and the number 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 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 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 bobbin 2 . The installation position of the pressing roller handle 13 is not limited, as long as it does not interfere with ...

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 wire pay-off frame, in particular to a constant tension wire pay-off frame. Background technique [0002] In the wire and cable industry, transformers and textile industries, pay-off racks are required. The existing pay-off racks cannot maintain a stable tension, and they are often tight and loose, causing unstable factors to the product quality. Chinese Patent Document No. CN201773697U discloses a coil pay-off frame, in which a brake is arranged beside the wire reel, and a cylinder and a wire passing wheel matched with the wire reel are arranged on the wire pay-off frame. Wire gauges provide different constant tensions. Because its tension is subject to the dual action of the brake and the wire-passing wheel cylinder, and the pressure on the wire is different depending on the degree of expansion and contraction of the cylinder (if the air pressure in the cylinder does not change, the pressure does not change when the cylin...
