It should be understood that the specific implementation described herein is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0014] See also Figure 1 A protective cover 33 device for a steel strip processing line includes an unwinding mechanism 10 and a straightening mechanism 20 arranged on one side of the unwinding mechanism 10, wherein the unwinding mechanism 10 includes a reel 11, and the reel 11 is used to unwind the steel coil into a steel strip, and the straightening mechanism 20 includes a frame 21 and a pinch roller group 22, and the pinch roller group 22 is installed on the frame 21 for clamping and conveying the steel strip.

[0015] A protective cover mechanism 30 is provided on the frame 21, and the protective cover mechanism 30 includes a first cylinder 31, a connecting member 32, a protective cover 33 and a rotating shaft 34. One end of the first cylinder 31 is hinged on the frame 21, and the other end is hinged to one end of the connecting member 32, and the other end of the connecting member 32 is fixed on the rotating shaft 34. One end of the protective cover 33 is fixed on the rotating shaft 34. In this embodiment, the protective cover 33 is arranged below the pinch roller group 22. When the steel coil is unwinding, the first cylinder 31 pushes the connecting member 32 to rotate together with the rotating shaft 34, and the rotating shaft 34 drives the protective cover 33 to swing to the side end of the frame 21 to receive the tail of the steel strip.

[0016] Specifically, the protection cover 33 includes a swinging portion 331 and an anti-collision portion 332 connected to the swinging portion 331, and one end of the swinging portion 331 is fixed on the rotating shaft 34. Figure 2 The first cylinder 31 pushes the swinging part 331 and the anti-collision part 332 to swing upward, and the end surface of the anti-collision part 332 is used to receive the tail of the steel belt.

[0017] See also Figure 1 , a belt connecting mechanism 40 is provided on the frame 21, and the belt connecting mechanism 40 includes a support frame 41, a belt connecting plate 42 and a second cylinder 43. The support frame 41 is arranged on the frame 21, one end of the belt connecting plate 42 is hinged to the side end of the support frame 41, one end of the second cylinder 43 is hinged to the side end of the support frame 41, and the other end is hinged to the belt connecting plate 42. When the steel coil on the reel 11 is unwound, the second cylinder 43 pushes the belt connecting plate 42 to swing around the side end of the support frame 41 to receive the steel belt head after the steel coil is unwound.

[0018] The support frame 41 is provided with a clamping mechanism 50, which includes a first clamping seat 51, a second clamping seat 52 and a third cylinder 53. The first clamping seat 51 is movably arranged at the top of the support frame 41, the second clamping seat 52 is fixedly arranged on the support frame 41 and located below the first clamping seat 51, and one end of the third cylinder 53 is fixedly arranged on the support frame 41, and the other end is connected to and supported at the bottom end of the first clamping seat 51 to support the lifting of the first clamping seat 51.

[0019] After the strip connecting plate 42 receives the head of the steel strip, it guides the steel strip to between the first clamping seat 51 and the second clamping seat 52. The third cylinder 53 pulls the first clamping seat 51 downward and close to the second clamping seat 52. The first clamping seat 51 and the second clamping seat 52 cooperate to clamp the steel strip so as to guide the steel strip to extend into the pinch roller group 22. The pinch roller group 22 rotates to transmit the steel strip.

[0020] Furthermore, one end of the anti-collision portion 332 extends laterally to form a guide portion 333 , and a groove is formed between the guide portion 333 and the anti-collision portion 332 , so that when the guide portion 333 swings to the position of the belt connecting plate 42 , the belt connecting plate 42 is accommodated in the groove.

[0021] Furthermore, the end surfaces of the anti-collision portion 332 and the guide portion 333 are covered with a protective layer to reduce the impact of the tail of the steel belt.

[0022] The method of using the present invention is as follows: Please refer to Figure 1When the steel strip unwound from the reel 11 of the unwinding mechanism 10 is guided to the strip connecting mechanism 40, the second cylinder 43 pushes the strip connecting plate 42 to swing upward around the side end of the support frame 41, so that the end face of the strip connecting plate 42 is parallel to the surface of the steel strip; after the strip connecting plate 42 receives the head of the steel strip, the steel strip is further guided by the strip connecting plate 42 to between the first clamping seat 51 and the second clamping seat 52; the third cylinder 53 pulls the second clamping seat 52 closer to the first clamping seat 51, so as to clamp the steel strip and transmit it to the pinch roller group 22. When the steel strip enters the pinch roller group 22, the third cylinder 53 pushes the first clamping seat 51 to slide upward back to its original position.

[0023] When the steel coil on the reel 11 is unwound, please refer to Figure 2 The first cylinder 31 pushes the connecting shaft 34 to rotate, and the shaft 34 drives the protective cover 33 to swing toward the side end of the frame 21. The tail of the steel belt swings toward the anti-collision part 332 of the protective cover 33 due to the action of gravity, and finally hits the surface of the anti-collision part 332. The anti-collision part 332 cooperates with the guide part 333 to accurately receive the tail of the steel belt. At this time, the connecting plate 42 is accommodated in the groove between the anti-collision part 332 and the guide part 333 to prevent the tail of the steel belt from hitting the connecting plate 42, and then the clamping roller group 22 continues to transport the steel belt forward for processing.

[0024] In summary, the present invention accurately receives the steel strip by providing a strip connecting plate 42; and receives the tail of the steel strip and withstands the impact of the tail of the steel strip by providing a protective cover 33, so as to prevent the tail of the steel strip from hitting the frame 21 of the straightening machine after the steel coil is unwound, thereby causing damage to the frame 21 and the steel strip. The present invention plays a good protective role and has the function of guiding the steel strip.
