[0002] Hot-rolled narrow strip steel, a key raw material in the steel processing industry, is experiencing growing market demand.

[0082] A tightening plate 306 is provided between the detection slide 304 and the detection linear motion component. A guide hole is provided on the tightening plate 306, and a tightening guide rod 310 is provided in the guide hole. The tightening guide rod 310 passes through the guide hole and is fixedly connected to the detection slide 304 with threads.

[0086] Working process:

[0087] The strapping operation process and the preparatory work before strapping are only performed before the first packaging or after the strapping tape 6 rolls are replaced. The outermost ring of the strapping tape 6 roll is manually fed into the strapping tape 6 feeding device. The strapping tape 6 head passes through the tensioning component 2, the tape length detection component 3, and the pinching component 4 in sequence until the strapping tape 6 head reaches the cutting position of the cutting component 5. Turn the handle in the tensioning component 2 to move the movable tensioning roller 202 toward the fixed tensioning roller 201, adjust the gap between the two, and tighten the strapping tape 6. Turn the handle in the tape length detection component 3 to move the tensioning roller 302 toward the detection roller 301 until the tensioning roller 302 presses the strapping tape 6 against the detection roller 301. The output shaft of the cylinder in the pinching component 4 is in a retracted state. A certain opening is maintained between the active pinching roller 402 and the driven pinching roller 401 to allow the strapping tape 6 to pass through. The output shaft of the hydraulic cylinder in the strap cutting assembly 5 is in a retracted state, and a certain gap is maintained between the movable cutting blade 502 and the fixed cutting blade 501 for the strapping strap 6 to pass through.

[0088] Tape feeding process:

[0089] The output shaft of the cylinder in the pinch assembly 4 extends, pushing the pinch slide 405 to move, causing the driven pinch roller 401 on the pinch slide 405 to press the strap 6 against the active pinch roller 402. The servo motor then drives the active pinch roller 402 to rotate, driving the strap 6 forward and conveying it through the shear assembly 5 toward the steel coil. Due to the clamping of the strap 6 by the tensioning assembly 2, a certain tension is generated in the strap 6 between the pinch assembly 4 and the tensioning assembly 2. Under the action of this tension, the strap 6 is straightened, facilitating subsequent conveying. During the conveying of the strap 6, the detection roller 301 of the strap length detection assembly 3 rotates passively, and the encoder 303 connected to it detects the conveyed length of the strap 6 in real time. When the encoder 303 detects that the conveyed length of the strap 6 reaches the set value, the pinch assembly 4 stops conveying the strap, and the output shaft of the hydraulic cylinder in the shear assembly 5 extends, rapidly pushing the movable shear blade 502 toward the fixed shear blade 501, cutting the strap 6.

[0090] The machine can automatically feed thick strapping tape 6 continuously during the packaging process, automatically control the length of the strapping tape, and automatically cut the strapping tape, thus realizing the automation of the strapping process and greatly improving the efficiency of steel coil packaging. The equipment is compact, simple and easy to maintain, reducing the labor intensity of workers.
