[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] Reference Figure 1-Figure 5 A steel plate straightening machine includes a base 1. A control box 42 is installed on one side of the bottom of the base 1. A controller is provided inside the control box 42. The controller is a PLC logic controller or a mainboard.

[0034] like Figure 1 and Figure 2 As shown, strip fixed plates 43 are symmetrically installed on the top of the base 1, and guide columns 2 are vertically installed at both ends of the top of each strip fixed plate 43. The tops of the two guide columns 2 on the same side are connected by a strip top plate 3, and a strip movable plate 4 is slidably connected between the two guide columns 2 on the same side. The tops of the two strip movable plates 4 are connected to the strip top plate 3 through a first hydraulic rod 5, and the first hydraulic rod 5 is connected to the controller through a wire. In actual use, the first hydraulic rod 5 can drive the strip movable plate 4 to move up and down along the guide column 2, and the distance between the strip movable plate 4 and the strip fixed plate 43 can be adjusted according to the thickness of the steel plate.

[0035] like Figure 1 and Figure 2As shown, several second straightening rollers 27 are rotatably connected between the two strip fixed plates 43, and several first straightening rollers 6 are rotatably connected between each strip movable plate 4, and the first straightening rollers 6 are located above the second straightening rollers 27 and are staggered with the second straightening rollers 27. A second pulley 34 is installed at one end of each second straightening roller 27, and two adjacent second pulleys 34 are connected by a belt, and the other end of one of the second straightening rollers 27 is connected to a first drive motor 28, which is fixed on the base 1 and connected to the controller through a wire. In actual use, when the steel plate moves between the first straightening roller 27 and the second straightening roller 6, the first drive motor 28 drives one of the second straightening rollers 27 to rotate, and under the action of the second pulley 34, all the second straightening rollers 27 can be driven to rotate synchronously to transport the steel plate, and during the transportation process, the first straightening roller 6 cooperates with the second straightening roller 27 to straighten the steel plate.

[0036] like Figure 2 and Figure 3 As shown, an open groove 15 is provided at one end of the top of the base 1, and a pair of strip uprights 22 are symmetrically installed at both ends of the inside of the open groove 15, and the tops of the strip uprights 22 are connected by a U-shaped top plate 33, and a lifting plate 17 is provided between the bottom ends of the two pairs of strip uprights 22, and a first fixed plate 20 is installed on both sides of the lifting plate 17. The top of the first fixed plate 20 is connected to the U-shaped top plate 33 through a third hydraulic rod 21, and the third hydraulic rod 21 is connected to the controller through a wire. In actual use, the lifting plate 17 can be moved to the bottom of the base 1 through the third hydraulic rod 21, and then the staff puts the steel plate on the lifting plate 17, and then lifts the lifting plate 17 to a preset height through the third hydraulic rod 21, which is convenient for loading.

[0037] It should be noted that if Figure 3 As shown, strip mounting plates 19 are installed on both sides of the top of the lifting plate 17, and the adjacent surfaces of the two strip mounting plates 19 are rotatably connected to a plurality of guide wheels 18, so that when placing the steel plate, the steel plate can be placed on the guide wheels 18, which makes it convenient to move the steel plate.

[0038] like Figure 2 and Figure 3As shown, a U-shaped plate 13 is provided between a pair of strip vertical plates 22, and the top of the U-shaped plate 13 is connected to the U-shaped top plate 33 through a second hydraulic rod 11, and the internal rotation of the U-shaped plate 13 is connected to at least one rotating wheel 14, and one end of the rotating wheel 14 is connected to a third drive motor 36, and the third drive motor 36 is fixed on the side of the U-shaped plate 13. The second hydraulic rod 11 and the third drive motor 36 are both connected to the controller through wires. In actual use, when the steel plate placed on the lifting plate 17 is lifted to a preset position, the staff controls the second hydraulic rod 11 to extend through the controller so that the bottom of the rotating wheel 14 contacts the top of the steel plate, and then drives the rotating wheel 14 to rotate through the third drive motor 36, and under the action of the guide wheel 18, the steel plate is transported toward the first straightening roller 6 and the second straightening roller 27, which is convenient for loading.

[0039] like Figure 1 and Figure 4 As shown, a U-shaped frame 7 is installed at one end of the top of the base 1 near the opening groove 15, and two second fixed plates 30 are symmetrically provided inside the U-shaped frame 7. The adjacent surfaces of the two second fixed plates 30 are rotatably connected to at least one cleaning roller 37, and the cleaning roller 37 is a wire brush roller. In this way, when in use, the cleaning roller 37 can scrape and clean the oxide on the steel plate.

[0040] like Figure 4 As shown, a first pulley 29 is installed at one end of each cleaning roller 37, a second drive motor 32 is installed on the side of the two second fixed plates 30 away from each other, and a third pulley 44 is installed at the drive shaft end of the second drive motor 32. The third pulley 44 is connected to the corresponding first pulley 29 through a belt, and the second drive motor 32 is connected to the controller through a wire. In actual use, when the steel plate moves between the two second fixed plates 30, the cleaning roller 37 contacts the surface of the steel plate. The second drive motor 32 can drive the cleaning roller 37 to rotate under the action of the first pulley 29 and the third pulley 44. The cleaning roller 37 will rotate relative to the surface of the steel plate to clean the oxide on the surface of the steel plate.

[0041] like Figure 4 As shown, at least one guide rod 9 is installed on the side away from each other of each second fixing plate 30, and a limiting sleeve 31 is installed on the inner top of the U-shaped frame 7 and the top of the base 1. One end of each guide rod 9 extends into the corresponding limiting sleeve 31. In actual use, the second fixing plate 30 can be limited by the cooperation of the limiting sleeve 31 and the guide rod 9, so that the second fixing plate 30 remains stable.

[0042] It should be noted that if Figure 5As shown, an anti-slip ring is installed at the internal opening of the limiting sleeve 31, and the inner diameter of the anti-slip ring is smaller than the diameter of the end of the guide rod 9 extending into the limiting sleeve 31, so as to prevent the guide rod 9 from slipping out of the limiting sleeve 31.

[0043] like Figure 5 As shown, a spring 41 is provided inside each limit sleeve 31, one end of the spring 41 is against the inside of the limit sleeve 31, and the other end of the limit sleeve 31 is against the end of the guide rod 9. Under the elastic force of the spring 41, the cleaning roller 37 is always in full contact with the surface of the steel plate, and the cleaning will not be affected by the bending of the steel plate.

[0044] like Figure 1 and Figure 4 As shown, the adjacent surfaces of the two second fixed plates 30 are both installed with flat nozzle adsorption heads 38, and the two flat nozzle adsorption heads 38 are symmetrically arranged, and an adsorption tube 26 is installed on one side of each flat nozzle adsorption head 38, and the other ends of the two adsorption tubes 26 are connected to the side of the collection box 25 through a pipe, and the collection box 25 is set on the top of the storage plate 24, and the top edge of the storage plate 24 is fixed to the top of the base 1 through the connecting rod 23. A negative pressure pump 35 is installed on one side of the top of the storage plate 24, and the negative pressure pump 35 is connected to a controller through a wire. The air inlet end of the negative pressure pump 35 is connected, and a negative pressure pipe 39 is installed. The other end of the negative pressure pipe 39 is fixed on the box cover 40, and the box cover 40 covers the top opening of the collection box 25. During actual use, the controller controls the operation of the negative pressure pump 35, and the negative pressure pump 35 sucks out the air in the collection box 25 through the negative pressure pipe 39, so that a negative pressure is generated inside the collection box 25. In this way, the adsorption tube 26 will cause the flat-mouth adsorption head 38 to generate suction, and the oxide debris cleaned by the cleaning roller 37 is adsorbed into the collection box 25 for collection.

[0045] Among them, a filter screen is installed at one end of the negative pressure pipe 39 close to the box cover 40. In this way, during use, the steel plate oxide debris sucked into the collection box 25 will be filtered out by the filter screen and will not be sucked into the negative pressure pump 35 along with the negative pressure pipe 39, thereby avoiding damage to the negative pressure pump 35.

[0046] It should be noted that the rotation direction of the cleaning roller 37 is the same as the moving direction of the steel plate, so that the oxides cleaned by the cleaning roller 37 can be adsorbed cleanly by the flat nozzle adsorption head 38.

[0047] Specifically, when the present invention is in use, the worker places the steel plate with tensioning and straightening on the lifting plate 17 so that both sides of the bottom of the steel plate are located on the guide wheels 18. Then the worker holds the steel plate and controls the third hydraulic rod 21 to retract through the controller. The third hydraulic rod 21 drives the lifting plate 17 to rise and moves the steel plate to a preset height. Then the second hydraulic rod 11 is controlled to extend, and the second hydraulic rod 11 pushes the U-shaped plate 13 downward so that the bottom of the rotating wheel 14 contacts the top of the steel plate. Then the third drive motor 36 is controlled to work, and the third drive motor 36 drives the rotating wheel 14 to rotate and move the plate toward the first tensioning and straightening roller 6 and the second tensioning and straightening roller 27. During the movement, the steel plate passes between the two second fixed plates 30. During the movement of the steel plate, the cleaning roller 37 contacts both sides of the steel plate. At the same time, the controller controls the second drive motor 32 and the negative pressure pump 35 to work. The second drive motor 32 is in the first The pulley 29 and the third pulley 44 drive the cleaning roller 37 to rotate, and clean the oxide debris attached to the surface of the steel plate. At the same time, the negative pressure pump 35 generates negative pressure in the collection box 25 through the negative pressure pipe 39, and the flat-mouth adsorption head 38 generates suction to adsorb the oxide debris cleaned by the cleaning roller 37 into the collection box 25 through the adsorption pipe 26 for collection. Then the steel plate moves between the first straightening roller 6 and the second straightening roller 27. At the same time, the controller controls the first hydraulic rod 5 to extend and move the first straightening roller 6 to a preset position so that the distance between the first straightening roller 6 and the second straightening roller 27 is the same as the thickness of the steel plate. At the same time, the controller also controls the first drive motor 28 to work. The first drive motor 28 drives the second straightening roller 27 to rotate, so that the steel plate can move between the first straightening roller 27 and the second straightening roller 6. During the movement, the first straightening roller 6 and the second straightening roller 27 straighten the steel plate.

[0048] Furthermore, Figure 3 As shown, guide rails 8 are installed on the adjacent surfaces of each strip vertical plate 22, and both ends of the lifting plate 17 are slidably connected to the guide rails 8 through sliders, and both ends of the U-shaped plate 13 are slidably connected to the guide rails 8 through connecting blocks 12. Under the action of the guide rails 8, the lifting plate 17 and the U-shaped plate 13 can be limited so that the lifting plate 17 and the U-shaped plate 13 remain stable.

[0049] Furthermore, the distance between the two strip-shaped mounting plates 19 is greater than the width of the U-shaped plate 13 , so that the U-shaped plate 13 will not collide with the strip-shaped mounting plates 19 when conveying the steel plate.

[0050] Furthermore, the distance between the two flat-nosed adsorption heads 38 is greater than the distance between the corresponding two cleaning rollers 37, so that when the corresponding two cleaning rollers 37 contact the two sides of the steel plate, there is a gap between the flat-nosed adsorption head 38 and the steel plate, so that the flat-nosed adsorption head 38 will not collide with the steel plate.

[0051] Furthermore, each second fixing plate 30 is installed with an arc plate 10 at one end close to the opening groove 15, and the arc plate 10 is bent outward. In this way, during use, the arc plate 10 can guide the steel plate to prevent the steel plate from getting stuck during transportation.

[0052] Furthermore, a plurality of pairs of legs 16 are symmetrically mounted at both ends of the bottom of the base 1 , and the legs 16 can support the base 1 so that the base 1 remains stable.

[0053] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
