[0044] The embodiment of the present invention first provides a steel strip shearing device, see Figure 1The figure shows the overall structure of the steel strip shearing device of the present invention. The steel strip shearing device mainly consists of three parts: an unwinding device 1, a cleaning device 2, and a shearing device 3; wherein the cleaning device 2 and the shearing device 3 are arranged on the first frame 4, and the unwinding device 1 and the shearing device 3 are located on both sides of the cleaning device 2. The steel strip coil is installed on the unwinding device 1 for unwinding, and the unwinding steel strip is sent to the shearing device 3 for shearing after being cleaned by the cleaning device 2.

[0045] In order to solve the technical problem of cleaning the surface of the steel strip before shearing, the cleaning device 2 provided by the present invention includes a front guide roller 2.1, a rear guide roller 2.2, a lower pressure roller 2.3, and a cleaning tank 2.4. Figure 2 The figure shows the structure of the cleaning device 2 of the present invention. A front guide roller 2.1 and a rear guide roller 2.2 are arranged in parallel on the first frame 4, and a lower pressure roller 2.3 is arranged between the front guide roller 2.1 and the rear guide roller 2.2; the lower pressure roller 2.3 is parallel to the front guide roller 2.1 and the rear guide roller 2.2, and the lower pressure roller 2.3 is arranged at a height lower than the front guide roller 2.1 and the rear guide roller 2.2; the front guide roller 2.1, the rear guide roller 2.2, and the lower pressure roller 2.3 are distributed in a triangular shape. A cleaning tank 2.4 with an opening at the top is arranged below the lower pressure roller 2.3, and a cleaning agent is stored in the cleaning tank 2.4. The cleaning agent can be a commercially available chemical cleaning agent or a water-based cleaning agent, and the present invention does not limit this. The length of the lower pressure roller 2.3 is less than the width of the top opening of the cleaning tank 2.4, so that the lower pressure roller 2.3 can press the steel strip into the cleaning tank 2.4 for cleaning.

[0046] An unwinding device 1 is arranged on one side of the front guide roller 2.1, and a shearing device 3 is arranged on one side of the rear guide roller 2.2. A conveying roller mechanism 5 is arranged between the rear guide roller 2.2 and the shearing device 3; the conveying roller mechanism 5 includes an active conveying roller 5.1 and an auxiliary conveying roller 5.2, and an auxiliary conveying roller 5.2 is arranged above the active conveying roller 5.1 in parallel, and a gap is left between the active conveying roller 5.1 and the auxiliary conveying roller 5.2 to allow the steel belt to pass through. One end of the active conveying roller 5.1 is connected to a first driving motor 5.3, and the first driving motor 5.3 is used to drive the active conveying roller 5.1 to rotate. The steel belt is driven by the conveying roller mechanism 5 to enter the shearing device 3.

[0047] The working principle of the steel strip shearing device of the present invention is as follows: the steel strip unwound from the unwinding device 1 passes through the front guide roller 2.1, the lower pressure roller 2.3, and the rear guide roller 2.2 in sequence; then passes through the gap between the active conveying roller 5.1 and the auxiliary conveying roller 5.2; and finally is sent to the shearing device 3 for shearing. When the steel strip passes under the lower pressure roller 2.3, it is immersed in the cleaning agent in the cleaning tank 2.4.

[0048] In one embodiment of the present invention, the cleaning tank 2.4 is an ultrasonic cleaning tank, and a chamber is provided on the bottom surface of the cleaning tank 2.4, and a transducer is provided in the chamber. The ultrasonic generator 6 generates high frequency and high voltage, which is transmitted to the transducer through the cable connection line, and the transducer and the bottom surface of the cleaning tank generate high frequency resonance together, so that the cleaning agent in the cleaning tank 2.4 is acted upon by the ultrasonic wave to clean the dirt on the steel strip.

[0049] like Figure 3 The figure shows the structure of a cleaning tank 2.4 of the present invention. In one embodiment of the present invention, the cleaning tank 2.4 is installed on a lifting trolley 7, and the lifting trolley 7 includes an upper support frame 7.1, a lower support frame 7.2, a cross-hinged frame 7.3, and a lifting telescopic rod 7.4.
