[0017] 1. In the present invention, by placing the steel plate in the working frame, the steel plate is overlapped on the guide assembly and the material guide assembly, the control adjustment assembly is moved downward and drives the shearing and striping assembly to move downward, so that the shearing and striping assembly squeezes the steel plate, and the shearing tool in the shearing and striping assembly can penetrate the steel plate. By controlling the material guide assembly to work, the material guide assembly can drive the steel plate to be transported to the right. Because multiple groups of shearing tools pass through the steel plate, the steel plate can be sheared and striped by multiple groups of shearing tools during the process of being transported to the right. The sheared and striped steel plate is then sent to the abrasive assembly, and the steel plate is located between two adjacent friction wheels.

[0029] A shearing stripping component 4 is installed at the bottom of the adjusting component 3, and the shearing stripping component 4 includes a support shaft 401. Both ends of the support shaft 401 are installed between the two ear plates 303, and the support shaft 401 is located below the partition bar 304.

The shearing tool 403 is installed outside the support shaft 401. Through the mutual cooperation between the spring 305 and the pressure roller 402, the spring 305 can be squeezed through the partition bar 304 during the downward pressing of the pressure roller 402. The partition bar 304 and the ear plate 303 are supported by the elastic force of the spring 305, which plays a role of supporting and buffering the pressure roller 402, preventing the excessive downward pressure of the pressure roller 402 from causing deformation or damage to the steel, and playing a role of protecting the steel plate.

[0030] A material guide assembly 5 is provided below the shearing and slitting assembly 4. The material guide assembly 5 is installed inside the working frame 1, and the two ends of the material guide assembly 5 pass through the front and rear sides of the working frame 1. Specifically, the material guide assembly 5 includes a motor 501, and a fixing block 502 is provided outside the motor 501. The fixing block 502 is fixed to the back of the working frame 1; the output shaft of the motor 501 is fixedly connected with a connecting shaft 503, and the connecting shaft 503 is installed on the working frame 1. The connecting shaft 503 is provided with a plurality of driving rollers 504.

The pressure roller 402 and the driving roller 504 clamp and limit the steel plate, thereby ensuring the stability of the shearing of the steel plate by the shearing tool 403, and preventing the steel plate from warping.

[0031] A guide assembly 6 is installed at one end of the material guide assembly 5. The guide assembly 6 is installed through one side of the work frame 1. The guide assembly 6 includes a guide roller 601. The guide roller 601 is installed on one side of the work frame 1. One end of the guide roller 601 is fixedly connected to a first driving wheel 602. A first belt 603 is connected to the outer surface of the first driving wheel 602. One side of the first belt 603 is connected to a first driven wheel 604. The first driven wheel 604 is fixed to the end of the connecting shaft 503. Due to the guide roller 601, the driving roller 504 drives the first driven wheel 604 to rotate. The first driven wheel 604 drives the first driving wheel 602 and the guide roller 601 to rotate through the first belt 603. During the rotation of the guide roller 601, the steel plate can be transported to the right, thereby improving the stability of the steel plate transportation.

[0032] The end of the material guide assembly 5 is connected to the transmission assembly 7, which includes a second driving wheel 701 and a second driven wheel 702. The second driving wheel 701 and the second driven wheel 702 are outerly connected with a second belt 703. The second driven wheel 702 is fixed to the end of the connecting shaft 503. The second driving wheel 701 is connected to the end of the abrasive assembly 8. The abrasive assembly 8 is installed on one side of the working frame 1, and the abrasive assembly 8 runs through the front and rear sides of the working frame 1. The abrasive assembly 8 and the guide assembly 6 are respectively located on both sides of the shearing and slitting assembly 4. The abrasive component 8 includes a slitting hollow shaft 801, and the two sides of the slitting hollow shaft 801 are respectively installed on the workbench 1 through sleeves. A plurality of friction wheels 802 are arranged outside the slitting hollow shaft 801, and a plurality of air holes 803 are equidistantly provided outside the slitting hollow shaft 801 near the friction wheel 802. One end of the slitting hollow shaft 801 is connected to the extraction component 9. Because of the friction wheel 802, the friction wheel 802 can grind and remove burrs on the cut surface of the steel plate, and cooperate with the air holes 803 to suck air, and the generated dust is absorbed by the air holes 803, thereby improving the cleaning effect on the steel surface.

[0033] An extraction assembly 9 is installed at one end of the abrasive assembly 8 away from the transmission assembly 7, and the extraction assembly 9 includes a fan 901, which is installed on the back of the workbench 1. A filter box 902 is installed at the air inlet end of the fan 901, and a connecting pipe 903 is installed on the filter box 902. A rotating joint 904 is provided at the other end of the connecting pipe 903, and the rotating joint 904 is connected to the end of the slitting hollow shaft 801, and the connecting pipe 903 is connected to the inside of the slitting hollow shaft 801. Because the rotating joint 904 is provided, the connecting pipe 903 is connected to the inside of the slitting hollow shaft 801 through the rotating joint 904. Therefore, during the rotation of the slitting hollow shaft 801, the connecting pipe 903 will not rotate synchronously, thereby ensuring the connection stability between the connecting pipe 903 and the slitting hollow shaft 801.

[0034] The extraction component 9 is fixedly connected to the back of the work frame 1. A plurality of guide rods 12 are installed on the side of the work frame 1 close to the abrasive component 8. A top plate 10 is provided above one of the guide rods 12. The top plate 10 is fixedly connected to the work frame 1. A flexible scraper 11 is provided below the top plate 10. The cross-sectional shape of the flexible scraper 11 is triangular. Due to the provision of the flexible scraper 11, the flexible scraper 11 is in contact with the surface of the steel plate. As the steel plate continues to be conveyed to the right, the flexible scraper 11 can isolate the impurities remaining on the surface of the steel plate on the left side of the top plate 10.

[0035] Operation holes 13 are respectively provided on the front and rear sides of the work frame 1, and a collection box 14 is provided between the two operation holes 13. The collection box 14 is overlapped on the base plate 2, and the front and rear sides of the collection box 14 are respectively fixedly connected with handles 15. Because of the collection box 14, granular impurities generated by grinding fall into the collection box 14 on the base plate 2, and the collection box 14 can be pulled by the handle 15 to move the collection box 14 out of the operation hole 13, so as to facilitate cleaning of impurities in the collection box 14.

[0036] The working principle of the present invention is:

[0037] When in use, the steel plate is placed on the guide roller 601 and the driving roller 504, and the two electric hydraulic rods 302 are controlled to work, so that the electric hydraulic rod 302 extends to drive the cross plate 301 to move downward, and the cross plate 301 drives the support shaft 401, the pressure roller 402 and the shearing tool 403 to move downward through the two ear plates 303, so that the pressure roller 402 contacts the top of the steel plate, and multiple shearing tools 403 penetrate the steel plate to achieve the purpose of shearing the steel plate into strips. The steel plate is clamped and limited by the pressure roller 402 and the driving roller 504. At the same time, the pressure roller 402 can squeeze the spring 305 through the spacer 304 during the downward pressing process, and the spacer 304 and the ear plate 303 are supported by the elastic force of the spring 305, thereby supporting and buffering the pressure roller 402.

[0038] The motor 501 is controlled to drive the driving roller 504 to rotate, and the driving roller 504 drives the first driven wheel 604 to rotate. The first driven wheel 604 drives the first driving wheel 602 and the guide roller 601 to rotate through the first belt 603. During the rotation of the guide roller 601, the steel plate can be transported to the right, and the driving roller 504 cooperates to transport the steel plate. During the process of transporting the steel plate to the right, it can be sheared and divided into strips by multiple sets of shearing tools 403.

[0039] The steel plate after shearing and slitting is fed into the abrasive assembly 8, and the steel plate is located between two adjacent friction wheels 802, and the friction wheel 802 contacts the cut surface of the steel plate. Because the connecting shaft 503 can drive the second driven wheel 702 to rotate, the second driven wheel 702 drives the second driving wheel 701 to rotate through the second belt 703, and the second driving wheel 701 drives the slitting hollow shaft 801 and the friction wheel 802 to rotate, so that the friction wheel 802 can grind and remove the burrs on the cut surface of the steel plate; At the same time, the fan 901 is working, and the connecting pipe 903 is connected to the inside of the slitting hollow shaft 801, so that the air holes 803 inside the slitting hollow shaft 801 can suck air, and the granular impurities generated by grinding fall into the collection box 14 on the bottom plate 2, and the dust generated is adsorbed by the air holes 803. The gas containing dust is filtered by the filter box 902 through the connecting pipe 903. The slitting hollow shaft 801 can rotate continuously, which can play a role in supporting and guiding the steel material and maintain the continuity of the steel plate feeding. The steel plate after grinding is overlapped on the guide rod 12, so that the flexible scraper 11 in the upper top plate 10 contacts the surface of the steel plate. As the steel plate continues to be transported to the right, the flexible scraper 11 can isolate the impurities remaining on the surface of the steel plate on the left side of the top plate 10, and fall into the collection box 14 through the gaps generated by the shearing of the steel plate.
