DETAILED DESCRIPTION

[0022] The technical scheme in the embodiments of the device will be clearly and completely described below with reference to the drawings in the embodiments of the device, so as to have a further understanding of the concept of the device, the solved technical problems, the technical features of the technical scheme and the brought technical effects.

[0023] As shown in Figures 1-3 A kind of open-tooth steel strip precision straightening device, including first U-shaped support frame 1, first guide wheel 2, second guide wheel 3, second U-shaped support frame 4, connecting rod 5, I-shaped wheel 6, collection rod 7, collection barrel 8 and collection disc 9;

[0024] First guide wheel 2, rotatably connected to the upper portion of first U-shaped support frame 1;

[0025] Second guide wheel 3, rotatably connected to the upper portion of first U-shaped support frame 1, and second guide wheel 3 is below first guide wheel 2, and gap for open-tooth steel strip is provided between second guide wheel 3 and first guide wheel 2;

[0026] Connecting rod 5, one end is hinged to the upper portion of second U-shaped support frame 4;

[0027] I-shaped wheel 6, rotatably disposed at the other end of connecting rod 5;

[0028] Collection barrel 8, disposed at the right side of second U-shaped support frame 4;

[0029] Collection rod 7, upper end is connected to the lower side of second guide wheel 3, and lower end extends to the upper side of collection barrel 8;

[0030] Collection disc 9, disposed at the right side of collection barrel 8, for collecting open-tooth steel strip.

[0031] When using the device, first, open-tooth steel strip is passed through the gap between first guide wheel 2 and second guide wheel 3, and first guide wheel 2 and second guide wheel 3 clamp open-tooth steel strip, so that open-tooth steel strip receives horizontal restraint stress during the collection process, and position correction is achieved on open-tooth steel strip; at the same time, saponification liquid attached to open-tooth steel strip flows along collection rod 7 to collection barrel 8 under the action of first guide wheel 2, second guide wheel 3 and gravity. Open-tooth steel strip is wound and stored by the rotation of collection disc 9, and because the unevenness of tightening force (the tightening force is generated by motor, and the force arm is different on the side close to motor and the side away from motor), the radius difference of two open-tooth steel strip collection discs is too large, so that the horizontal tension received by open-tooth steel strip of the collection disc with smaller radius is smaller, and at this time, I-shaped wheel 6 is lowered to press open-tooth steel strip with smaller horizontal tension, so that open-tooth steel strip is tightened to the same tension received by two open-tooth steel strips.

[0032] As shown in Figure 2 As a preferred embodiment, first stabilizing rod 10 is horizontally disposed between first U-shaped support frame 1 and second U-shaped support frame 4. In the embodiment, first stabilizing rod 10 connects first U-shaped support frame 1 and second U-shaped support frame 4, and plays a reinforcing role.

[0033] As shown in Figure 2As shown, in a preferred embodiment, a second stabilizing rod 11 is also included, vertically disposed on the side wall of the first U-shaped support frame 1, and fixedly connected to the middle of the collecting rod 7. In this embodiment, since the collecting rod 7 is inclined, the second stabilizing rod 11 is provided to strengthen the connection and ensure the stability of the device in order to better maintain its angle.

[0034] like Figure 2 As shown, in a preferred embodiment, a support base 12 is also included, disposed on the top of the second U-shaped support frame 4, for supporting the I-beam wheel 6. In this embodiment, the I-beam wheel 6 is hinged to the second U-shaped support frame 4. When the I-beam wheel 6 is not in operation, it can be flipped upwards and rested against the support base 12 for temporary rest. When in operation, it can also be flipped downwards directly, which is simple and convenient.

[0035] like Figure 3 As shown, in a preferred embodiment, it also includes two square supports 13, which are respectively disposed on both sides of the inside of the first U-shaped support frame 1; the first guide wheel 2 and the second guide wheel 3 are connected to the square supports 13 through bearings; after the toothed steel strip passes through the gap between the first guide wheel 2 and the second guide wheel 3, it is tapped with a manual tap 14 to adjust the gap between the first guide wheel 2 and the second guide wheel 3, so that the first guide wheel 2 presses the toothed steel strip tightly. In this embodiment, the first guide wheel 2 and the second guide wheel 3 are connected to the first U-shaped support frame 1 through bearings and square supports 13. During installation, the rollers are relatively loose before the tap, with a range of 0-5mm. After the toothed steel strip passes through, it is fixed by tapping with a manual tap 14, thus providing a certain adjustment range to adapt to toothed steel strips of different widths.
