Detailed ways

Referring to accompanying drawings 1-2: the reed automatic straightening device includes a quenching furnace 1 and a workbench 2 on one side of the quenching furnace 1 . The reed conveying device and the reed straightening device are installed side by side on the upper plane of the workbench 2, and a support frame 3 is supported and fixed above the reed conveying device and the reed straightening device, and a control device is installed on the support frame 3. The power unit 9 on one side of the sheet extrusion device is connected. The power unit 9 is a hydraulic oil cylinder, and identical two sets are arranged side by side, and two sets of hydraulic oil cylinders work simultaneously.

The reed straightening device includes a support block 4 and a straightening block 5, the support block 4 is fixed on the upper plane of the workbench 2, and the straightening block 5 is slidably arranged above the support block 4, which is an iron block with a smooth surface on one side, and the other side Connect the power unit. The straightening block 5 squeezes and straightens the reed after outputting power through the power unit.

Reed conveying device comprises conveying roller 6 and block 7, and a plurality of conveying rollers 6 are placed side by side on the side of support block 4 on workbench 2, and the outer end of conveying roller 6 is provided with sprocket chain mechanism 8, and chain The wheel chain mechanism 8 drives a plurality of conveying rollers 6 to rotate to convey the reed. Block 7 is fixed between conveying roller 6 and sprocket chain mechanism 8 along conveying roller 6 transmission directions, and block 7 adapts to the length of straightening block 5, and the side surface toward straightening block 5 is smooth. The block 7 cooperates with the straightening block 5 to jointly extrude the straightening reed.

The control device includes a swing arm 10, a cross bar 11 and a proximity switch 12. The cross bar 11 is suspended horizontally on the support frame 3.
