[0025] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0026] like Figure 1-4 As shown, a metal sheet cutting device includes a frame 1 and a conveyor belt 2 installed on the frame 1 for conveying metal sheets; one end of the conveyor belt 2 is connected to a cutting table 3, and a first limiting plate 4 and a second limiting plate 5 are respectively provided on the frame 1, and the first limiting plate 4 and the second limiting plate 5 are respectively located on both sides of the conveyor belt 2, and a plurality of evenly distributed rollers 6 are provided on the side where the first limiting plate 4 and the second limiting plate 5 are close to each other. The rollers 6 of the first limiting plate 4 and the second limiting plate 5 respectively limit the two sides of the metal sheet to prevent the metal sheet from being tilted and the metal sheet from being tilted along the directions of the two sides of the conveyor belt 2, thereby preventing the cut end of the metal sheet from being tilted;

[0027] The first limiting plate 4 is fixed on the frame 1, and the limiting block 9 is fixedly connected to the frame 1. The bottom of the limiting block 9 is provided with a sliding hole 10 that passes through and slides with the second limiting plate 5. The four corners of the bottom of the second limiting plate 5 are provided with pulleys 16. The pulleys 16 can facilitate the movement of the second limiting plate 5; the second limiting plate 5 can slide in the direction close to or away from the first limiting plate 4. By changing the distance between the second limiting plate 5 and the first limiting plate 4, metal plates of different widths can be limited, thereby increasing practicality; the limiting block 9 A threaded hole 11 communicating with the sliding hole 10 is provided at the top of the threaded hole 11, and a screw 12 is connected to the inner thread of the threaded hole 11. One end of the screw 12 is provided with a pressure block 13 in contact with the top of the second limiting plate 5, and the other end is provided with a hand wheel 14. The hand wheel 14 drives the screw 12 to rotate, so that the screw 12 is lowered or raised along the length direction of the threaded hole 11, thereby tightening or loosening the second limiting plate 5; a push-pull handle 15 is provided on the side of the second limiting plate 5 away from the first limiting plate 4, which is convenient for moving the second limiting plate 5 by the push-pull handle 15;

[0028] A cutting knife 7 is provided above the cutting table 3. A bracket 18 is provided on the cutting table 3. A cylinder 17 is fixed on the bracket 18. The output end of the cylinder 17 is fixedly connected to a support plate 19. The cutting knife 7 is fixed to the bottom of the support plate 19. Two pressing plates 8 are elastically connected to the bottom of the support plate 19. The two pressing plates 8 are symmetrically arranged about the cutting knife 7. The support plate 19 is driven to rise or fall by the cylinder 17, thereby driving the cutting knife 7 and the pressing plate 8 to rise or fall. The distance between the pressing plate 8 and the cutting table 3 is smaller than the distance between the cutting knife 7 and the cutting table 3, so that the pressing plate 8 can first press the metal sheet before the cutting knife 7 cuts the metal sheet.

[0029] The top of the pressure plate 8 is provided with a number of evenly distributed sliding rods 20, and the support plate 19 is provided with through holes 21 that correspond one to one with the sliding rods 20 and slide in conjunction with the through holes 21. The sliding conjunction between the sliding rods 20 and the through holes 21 can improve the stability of the pressure plate 8 when it descends or ascends. The outer periphery of the sliding rod 20 is sheathed with a spring 22, one end of the spring 22 is connected to the top of the pressure plate 8, and the other end is connected to the bottom of the support plate 19. By utilizing the elastic effect of the spring 22, the pressure plate 8 can be pressed against the metal sheet. The end of the sliding rod 20 away from the pressure plate 8 passes through the through hole 21 and is provided with a support block 23, which supports the sliding rod 20 and the pressure plate 8.

[0030] The cutting table 3 is provided with a slot 24 for the cutting blade 7 to penetrate. The side of the cutting table 3 away from the conveyor belt 2 is provided with an inclined sliding surface 25 so that the cut metal sheet can slide down along the inclined sliding surface 25.

[0031] Working principle:

[0032] like Figure 1-4As shown, before using the metal sheet cutting device, the metal sheet to be cut is first placed on the unopened conveyor belt 2, and then the distance between the second limit plate 5 and the first limit plate 4 is changed according to the width of the metal sheet. The second limit plate 5 is moved by pushing and pulling the handle 15, so that the rollers 6 of the first limit plate 4 and the second limit plate 5 respectively press and limit the two sides of the metal sheet, and then the screw 12 is driven to rotate by the hand wheel 14, so that the screw 12 descends or ascends along the length direction of the threaded hole 11, pressing the second limit plate 5;

[0033] After the adjustment of the second limit plate 5 is completed, the cutting equipment is started, and the conveyor belt 2 will drive the metal sheet to move towards the cutting table 3. When the position where the metal sheet needs to be cut moves to directly below the cutting knife 7, the cylinder 17 drives the support plate 19 to descend, and drives the cutting knife 7 and the pressure plate 8 to descend. Before the cutting knife 7 cuts the metal sheet, the two pressure plates 8 will first press the two sides of the metal sheet to be cut to prevent the metal sheet from jumping during the cutting process, thereby improving the cutting quality.

[0034] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
