[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0026] The present invention provides a technical solution:

[0027] Please refer to Figures 1 to 4, a shearing machine with adjustable cutting width, including a shearing machine base 1. A chute 2 is provided inside the shearing machine base 1. An adjusting mechanism for adjusting the cutting width of the plate is connected inside the chute 2. A cutting mechanism for cutting the plate is fixed at the upper end of the shearing machine base 1. A conveying mechanism for conveying the plate is fixed on the right side of the shearing machine base 1;

[0028] The adjusting mechanism includes movable rods 3. There are two movable rods 3. Both of the two movable rods 3 are slidably connected inside the chute 2. Limit plates 31 are fixed on the left sides of the two movable rods 3. Scale tables 32 are provided on the side walls of the two movable rods 3. Sliders 33 slidably connected to the chute 2 are fixed on the right sides of the two movable rods 3. A fixing bolt 34 in contact connection with the movable rod 3 is installed on the outer wall of the shearing machine base 1. The cutting mechanism includes a fixing frame 4. The fixing frame 4 is fixed at the upper end of the shearing machine base 1. Two hydraulic cylinders 41 are fixed on the upper surface of the fixing frame 4 by bolts. The telescopic ends of the two hydraulic cylinders 41 penetrate through the fixing frame 4 and are fixed with a mounting member 42. A cutting knife 43 is installed inside the mounting member 42. A fixing screw 44 is installed on the side wall of the mounting member 42. The end of the fixing screw 44 is in contact connection with the side wall of the cutting knife 43.

[0029] By adopting the above technical solution, before using this shearing machine with adjustable cutting width, first place the shearing machine base 1 in a suitable position. When one end of the plate moves to the side wall of the limit plate 31, the conveying motor 51 stops running. The hydraulic cylinder 41 provided on the fixing frame 4 drives the mounting member 42 to move vertically, and then drives the cutting knife 43 to move to cut the plate below. And by unscrewing the fixing screw 44 on the mounting member 42, the fixing of the cutting knife 43 can be released, which is convenient for replacing the cutting knife 43. When it is necessary to cut plates of different widths, the fixing bolt 34 can be loosened so that the end of the fixing bolt 34 is separated from the movable rod 3. With the cooperation of the chute 2, the limit plate 31 can be pulled to move horizontally to adjust the distance between the limit plate 31 and the shearing machine base 1. The provided slider 33 can play a limiting role to prevent the movable rod 3 from being pulled too much, and the scale table 32 is convenient for observing the adjusted length, so as to realize limiting plates of different widths and facilitate cutting plates of different widths without replacing different shearing machines, with strong practicability.

[0030] Specifically, such as Figures 1 - 4As shown in the figure, the conveying mechanism includes mounting plates 5. There are two mounting plates 5, and both of the two mounting plates 5 are fixed to the right side of the shearing machine base 1. A conveying motor 51 is fixed to the side wall of one of the mounting plates 5. A conveying roller 52 is fixed to the power output shaft of the conveying motor 51. An auxiliary roller 53 is arranged above the conveying roller 52. Fixed bearings 54 are sleeved at both ends of the auxiliary roller 53. An outer wall of the fixed bearing 54 is fixed with a movable block 55. A limiting rod 56 penetrates through an inner surface of the movable block 55. An upper end of the movable block 55 is abutted and connected with a spring 57 sleeved on the limiting rod 56.

[0031] By adopting the above technical solution, the plate to be processed is placed between the conveying roller 52 and the auxiliary roller 53. The conveying motor 51 arranged on the mounting plate 5 can drive the conveying roller 52 to rotate, thereby conveying the plate. Through the fixed bearing 54 arranged in the movable block 55, when the plate moves, the auxiliary roller 53 can rotate under the action of friction force, thereby ensuring the conveying of the plate. And through the spring 57 arranged on the limiting rod 56, it can push the movable block 55 to move vertically, thereby adjusting the distance between the auxiliary roller 53 and the conveying roller 52, which is convenient for conveying plates of different thicknesses.

[0032] Working principle: The shearing machine base 1 is placed at a suitable position. The plate to be processed is placed between the conveying roller 52 and the auxiliary roller 53. The conveying motor 51 arranged on the mounting plate 5 can drive the conveying roller 52 to rotate, thereby conveying the plate. Through the fixed bearing 54 arranged in the movable block 55, the conveying of the plate is ensured. And through the spring 57 arranged on the limiting rod 56, it can push the movable block 55 to move vertically, thereby adjusting the distance between the auxiliary roller 53 and the conveying roller 52, which is convenient for conveying plates of different thicknesses. When one end of the plate moves to the side wall of the limiting plate 31, the conveying motor 51 stops operating. The hydraulic cylinder 41 arranged on the fixed frame 4 drives the mounting member 42 to move vertically, thereby driving the cutting knife 43 to move and cutting the lower plate. And by unscrewing the fixing screw 44 on the mounting member 42, the fixing of the cutting knife 43 can be released, thereby facilitating the replacement of the cutting knife 43. When plates of different widths need to be cut, the fixing bolt 34 can be loosened so that the end of the fixing bolt 34 is separated from the movable rod 3. With the cooperation of the sliding groove 2, the limiting plate 31 can be pulled to move horizontally to adjust the distance between the limiting plate 31 and the shearing machine base 1, which is convenient for cutting plates of different widths.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
