[0022] With the assembly gap of waste chute 2, it is generally lower shear frame. Wherein, the above-mentioned assembly gap is generally in the range of 20~50mm, usually about 30mm.

[0023] A slot width direction of waste chute 2 is defined, which is matched with the width direction of strip steel, so the slot width direction is parallel to the length direction of shear blade in shearing machine 1. Wherein, the axial direction of press roll 3 is parallel to the above-mentioned slot width direction.

[0024] The press roll 3 is preferably installed on the waste chute 2, which is convenient to install and easy to close the above-mentioned assembly gap.

[0025] In one embodiment, the press roll 3 is rubber-coated roll, which can improve the service life of press roll 3, and the rubber layer has certain elasticity and compressibility, which can eliminate the cumulative error of parts manufacturing and assembly, so as to better close the above-mentioned assembly gap.

[0026] In the embodiment, by setting the press roll 3 to close the assembly gap between the waste chute 2 and the shear frame 12, the waste material cut off can be prevented from falling from the assembly gap, so as to improve the production reliability of the shear device and improve the production safety; the rotatable press roll 3 not only does not affect the assembly of waste chute 2, but also can better withstand the impact of waste material, while ensuring the smoothness of strip steel blanking.

[0027] In one embodiment, the end bearing seat of the press roll 3 is provided with adjusting gasket, which is configured to make the press roll 3 cross the assembly gap to just contact with the structure on the other side, that is, the safety height of end bearing seat can be adjusted by increasing or decreasing gasket or replacing gasket with different thickness, so that the press roll 3 can better close the above-mentioned assembly gap, while ensuring its rotatability.

[0028] In one embodiment, as Figures 1-3The waste chute 2 is provided with a flap mechanism, which includes a movable flap 41 hingedly mounted on the chute bottom plate 21 and a flap driving unit 42 for driving the movable flap 41 to rotate about the hinge shaft 43. The hinged end of the movable flap 41 is the end away from the mounting end. By driving the movable flap 41 to rotate, the waste on the chute bottom plate 21 is lifted at an angle. Under the impact of the movable flap 41 and the weight of the waste, the waste can slide down, thereby reducing / eliminating the waste jamming and retention.

[0029] Optionally, the chute bottom plate 21 is provided with a notch, and the movable flap 41 is arranged at the notch. The flap driving unit 42 is located below the waste chute 2 and connected with the lower plate surface of the movable flap 41.
