Through operation observation, the operation is stable, and the expected yield and benefit target is achieved.

[0032] In a preferred scheme of the embodiment, the box type groove 2 further includes a first support plate 4, a first nut 5, a second support plate 6 and a second nut 7, the top of the first support plate 4 is provided with a first mounting groove 8, the top of the second support plate 6 is provided with a second mounting groove, the first support plate 4 and the second support plate 6 are arranged in parallel, the first end of the rotating shaft of the carrier roller 3 is threadedly connected with the first nut 5 through the first mounting groove 8, and the second end of the rotating shaft of the carrier roller 3 is threadedly connected with the second nut 7 through the second mounting groove.

[0033] In a preferred scheme of the embodiment, the carrier roller 3 is a rubber carrier roller 3, which has good flexibility and elasticity. On the one hand, this makes the rubber carrier roller 3 better fit the surface of the steel plate when in contact with the steel plate, increases the friction, and ensures the stability of the steel plate during conveying, so that the steel plate is not easy to slip. On the other hand, the rubber carrier roller 3 is relatively soft, which can provide a certain buffering protection for the steel plate, avoid causing scratches and other damages to the surface of the steel plate due to hard contact, and improve the quality of the product; on the other hand, it has elastic buffering, which effectively reduces the height adjustment precision requirement of the carrier roller 3.

[0034] In a preferred scheme of the embodiment, the top surface of the carrier roller 3 is 5-10mm higher than the top surface of the guard plate 1, which limits the top surface of the carrier roller 3 to be 5-10mm higher than the top surface of the guard plate 1, so as to ensure that the carrier roller 3 is in full contact with the steel plate and provides sufficient supporting force, and to ensure the stable conveying of the steel plate during the cutting process. This height range avoids the interference problem with the surrounding equipment caused by the carrier roller 3 being too high, and ensures that the carrier roller 3 can effectively undertake the functions of replacing the disc roller 9 to support and transport the steel plate, and optimizes the working performance of the entire device.

[0035] In a preferred scheme of the embodiment, a plurality of first pads and a plurality of second pads are further included, and the first pads and the second pads are respectively used to be placed in the first installation groove and the second installation groove to adjust the relative position between the top section of the carrier roller 3 and the top surface of the guard plate, and the first pads and the second pads provide a means for accurately adjusting the height of the carrier roller 3. Pads of different thicknesses can be combined according to actual needs to adjust the relative position between the top section of the carrier roller 3 and the top surface of the guard plate 1, so that the height of the carrier roller 3 can better adapt to the processing requirements of steel plates of different specifications. This accurate adjustment can ensure that the steel plate maintains good flatness during conveying and improve the processing accuracy and product quality of the cut-to-size shear.

[0036] In a preferred scheme of the embodiment, the number of box grooves 2 is four, and the four box grooves 2 are evenly arranged in the length direction of the guard plate 1. Arranging the number of box grooves 2 to be four and evenly distributing them in the length direction of the guard plate 1 can provide uniform support for the steel plate in the width direction. This can avoid problems such as warping or deviation of the steel plate during conveying due to uneven support, ensure that the steel plate is always in a stable state, and is especially suitable for cut-to-size shear operation of long-size steel plates, thereby improving the stability and accuracy of the entire processing process.

[0037] In a preferred scheme of the embodiment, the axis lines of the carrier rollers 3 are arranged in a line. Arranging the axis lines of the carrier rollers 3 in a line ensures the stability and consistency of the entire device in supporting and conveying the steel plate. This makes the force on the steel plate uniform on the plurality of carrier rollers 3, enabling the steel plate to be conveyed in a straight and stable manner, and preventing the steel plate from shaking or deviating due to inconsistent axis lines of the carrier rollers 3, thereby ensuring the smooth operation of the cut-to-size shear, improving the processing accuracy, and being conducive to improving product quality and production efficiency.
