[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] A steel plate feeding device for a plate rolling machine, such as Figure 1, including a plate rolling machine body 1, a bottom plate 2, a vertical plate 3, and a pallet 4 for placing steel plates. The bottom plate 2 is located at the front side of the plate rolling machine body 1, the vertical plate 3 is vertically arranged at the top of the bottom plate 2, and one side of the vertical plate 3 is provided with a mounting frame 5 through a transfer member, and a plurality of conveying rollers 6 are rotatably connected above the left and right sides of the mounting frame 5, and each conveying roller 6 is distributed at intervals along the length direction of the mounting frame 5. The pallet 4 is placed on the top of the bottom plate 2 and is located below the mounting frame 5. The transfer member is used to transfer the steel plate on the pallet 4 to the conveying roller 6 in the mounting frame 5. A conveying motor 7 and a chain transmission mechanism 8 are provided on one side of the outer wall of the mounting frame 5, and the conveying rollers 6 are uniformly driven by the conveying motor 7 through the chain transmission mechanism 8.

[0022] like Figure 1 , place the tray 4 with the steel plate on one side of the vertical plate 3 on the bottom plate 2, at which time the tray 4 is located below the mounting frame 5, and then transfer a steel plate on the tray 4 to the conveying roller 6 in the mounting frame 5 through the transfer member, without manually taking the steel plate and placing it on the conveying roller 6, which saves manpower and realizes the purpose of automatically placing the steel plates on the conveying roller 6 piece by piece; After a steel plate on the pallet 4 is transferred to the conveying roller 6 in the installation frame 5, the conveying motor 7 drives the conveying rollers 6 to rotate uniformly through the chain transmission mechanism 8, and the steel plate on the conveying roller 6 is sent to the plate rolling machine body 1 for processing. The plate rolling machine body 1 can be a three-roller plate rolling machine, which is simple and convenient to use.

[0023] like Figure 1 and Figure 2 The transfer member includes a moving frame 9 vertically slidably connected to one side of the vertical plate 3 through a moving member, the mounting frame 5 is rotatably connected between the front and rear sides of the moving frame 9, and the moving frame 9 is provided with a servo motor 10 for driving the mounting frame 5 to rotate, a U-shaped fixing frame 12 is provided at the bottom end of the mounting frame 5, and the fixing frame 12 is provided with a suction member for sucking the steel plate on the pallet 4 from between two adjacent conveying rollers 6, and the servo motor 10 is located on the side of the moving frame 9 away from the plate rolling machine body 1.

[0024] like Figure 1 and Figure 2 When a steel plate on the tray 4 needs to be transferred to the conveying roller 6 in the installation frame 5, the servo motor 10 is turned on, and the rotating shaft of the servo motor 10 drives the installation frame 5 to rotate 180 degrees in the moving frame 9 (such as Figure 6), then the servo motor 10 stops working, the moving part drives the moving frame 9 to move vertically downward, at this time the installation frame 5 moves with the moving frame 9, when the moving frame 9 moves downward to a suitable position, the steel plate on the tray 4 is sucked by the suction part, and then the moving frame 9 moves vertically upward, at this time a steel plate on the tray 4 will follow the installation frame 5 and the moving frame 9 to move upward through the suction part, when the moving frame 9 moves upward back to its original position, the rotating shaft of the servo motor 10 drives the installation frame 5 to rotate 180 degrees in the opposite direction in the moving frame 9 (such as Figure 2 ), completes a reciprocating rotation of the mounting frame 5, at this time the steel plate sucked by the suction member will be located above the conveying roller 6, and then the sucked steel plate is placed on the conveying roller 6 by the suction member. Through the above process, a steel plate on the tray 4 can be transferred to the conveying roller 6 in the mounting frame 5, without the need to manually take the steel plate and place it on the conveying roller 6, thus saving manpower.

[0025] like Figure 2 The movable member includes two first slide grooves 13 vertically opened on one side of the vertical plate 3, and the two first slide grooves 13 are vertically slidably connected with a first slide seat 14, the two first slide seats 14 are fixedly connected to the moving frame 9 on one side close to the moving frame 9, a second slide groove 15 is vertically opened on one side of the vertical plate 3, and the second slide groove 15 is located between the two first slide grooves 13, a second slide seat 16 is vertically slidably connected in the second slide groove 15, and the second slide seat 16 is fixedly connected to the moving frame 9, a first screw rod 17 is rotatably connected between the upper and lower side groove walls of the second slide groove 15, one end of the first screw rod 17 passes through the second slide seat 16 and is threadedly connected to the second slide seat 16, and a first driving motor 18 for driving the first screw rod 17 to rotate is provided at the top of the vertical plate 3.

[0026] like Figure 2 When it is necessary to drive the moving frame 9 to move vertically, it is only necessary to turn on the first driving motor 18, and the rotating shaft of the first driving motor 18 drives the first screw rod 17 to rotate. At this time, because one end of the first screw rod 17 passes through the second slide seat 16 and is threadedly connected with the second slide seat 16, and the second slide seat 16 is connected to the moving frame 9, when the first screw rod 17 rotates, it will drive the second slide seat 16 to move vertically in the second slide groove 15, and the second slide seat 16 will drive the moving frame 9 to move vertically on one side of the vertical plate 3. When the moving frame 9 moves vertically, the moving frame 9 will drive the first slide seat 14 to move in the first slide groove 13. Through the cooperation of the first slide seat 14 and the first slide groove 13, the stability of the moving frame 9 during vertical movement can be improved, and it is simple and convenient to use.

[0027] like Figure 2 and Figure 3The suction device includes a horizontally arranged mounting plate 19 and a plurality of vertical pipes 20 vertically arranged on the top of the mounting plate 19. The mounting plate 19 is located in the mounting frame 5 and below each conveying roller 6. An electric cylinder 21 for pushing the mounting plate 19 to move vertically is provided on the fixed frame 12. A vacuum suction cup 22 is provided on the top of each vertical pipe 20. Each vacuum suction cup 22 is staggered with each conveying roller 6, and the vacuum suction cup 22 is located between two adjacent conveying rollers 6.

[0028] like Figure 2 and Figure 3 , the mounting plate 19 is provided with a hose (not shown in the figure) connected to the vertical pipe 20, and the hose is connected to the vacuum pump (not shown in the figure). When the conveying roller 6 is located above the left and right sides of the mounting frame 5, the vacuum suction cup 22 faces upward. When the rotating shaft of the servo motor 10 drives the mounting frame 5 to rotate 180 degrees in the moving frame 9, the vacuum suction cup 22 faces downward, and the conveying roller 6 is located below the left and right sides of the mounting frame 5 (such as Figure 6 ), when the moving frame 9 moves downward to a suitable position, the piston rod of the electric cylinder 21 pushes the mounting plate 19 close to the conveying roller 6, so that the vacuum suction cup 22 passes between two adjacent conveying rollers 6 and contacts the steel plate on the tray 4, and the steel plate is sucked by the vacuum suction cup 22; Then the moving frame 9 moves vertically upward. When the moving frame 9 moves back to its original position, the rotating shaft of the servo motor 10 drives the installation frame 5 to rotate 180 degrees in the opposite direction in the moving frame 9 to complete a reciprocating rotation of the installation frame 5. At this time, the steel plate sucked by the vacuum suction cup 22 will be located above the conveying roller 6. Then the suction of the steel plate by the vacuum suction cup 22 is released. After the release, the steel plate is still located on the vacuum suction cup 22. Then the piston rod of the electric cylinder 21 pushes the installation plate 19 away from the conveying roller 6, so that the vacuum suction cup 22 passes between two adjacent conveying rollers 6 and moves to the bottom of the conveying roller 6. In this process, the steel plate on the vacuum suction cup 22 will be affected by gravity and follow the vacuum suction cup 22 to approach the conveying roller 6 until the bottom end of the steel plate contacts the conveying roller 6. At this time, the steel plate can be stably placed on the conveying roller 6. Through the above process, a steel plate on the tray 4 can be transferred to the conveying roller 6 in the installation frame 5, without the need to manually take the steel plate and place it on the conveying roller 6, saving manpower.

[0029] like Figure 6When the steel plate on the tray 4 is sucked by the vacuum suction cup 22, a cleaning part for cleaning impurities on the steel plate is provided at the bottom of the moving frame 9, and the cleaning part includes a U-shaped slide 23 horizontally slidably connected to the bottom of the moving frame 9, and the bottom end inside the slide 23 and the bottom end outside the slide are both detachably connected with a cross plate 24, and the two cross plates 24 are provided with bristles 25 on the sides facing away from each other, and the bottom end of the moving frame 9 is provided with two opposite baffles 26, and a second screw rod 27 located on one side below the mounting frame 5 is rotatably connected between the two baffles 26, and one end of the second screw rod 27 passes through the slide 23 and is threadedly connected to the slide 23, and a second drive motor 28 for driving the second screw rod 27 to rotate is provided on one of the baffles 26.

[0030] like Figure 6 , after the moving frame 9 moves downward to a suitable position, the bristles 25 on the outer side horizontal plate 24 of the slide 23 will be located on the left side of the steel plate on the tray 4. At this time, by turning on the second drive motor 28, the rotating shaft of the second drive motor 28 drives the second screw rod 27 to rotate. At this time, because one end of the second screw rod 27 passes through the slide 23 and is threadedly connected to the slide 23, and the slide 23 is horizontally slidably connected to the bottom end of the moving frame 9, when the second screw rod 27 rotates, the slide 23 can be driven to move along the width direction of the moving frame 9. When the slide 23 moves from the left side of the bottom end of the moving frame 9 to the right side, the bristles 25 on the outer side horizontal plate 24 of the slide 23 will contact the upper surface of the steel plate, thereby cleaning the impurities on the upper surface of the steel plate; After cleaning, the steel plate is sucked by the vacuum suction cup 22. After the vacuum suction cup 22 sucks the steel plate, the piston rod of the electric cylinder 21 pushes the mounting plate 19 away from the conveying roller 6, lifts the steel plate and aligns the steel plate sucked by the vacuum suction cup 22 with the slide 23, and then the electric cylinder 21 stops working. At this time, the steel plate and the conveying roller 6 are not in contact, and then the moving frame 9 moves upward back to its original position, and then the rotating shaft of the second drive motor 28 drives the second screw rod 27 to rotate in the opposite direction, so that the slide 23 moves from the right side of the bottom end of the moving frame 9 to the left side. At this time, the steel plate sucked by the vacuum suction cup 22 is aligned with the slide 23. The steel plate will pass through the slide 23, and the bristles 25 on the horizontal plate 24 inside the slide 23 will contact the lower surface of the steel plate, thereby cleaning the impurities on the lower surface of the steel plate. After the impurities on the upper and lower surfaces of the steel plate are cleaned, the rotating shaft of the servo motor 10 drives the mounting frame 5 to rotate 180 degrees in the opposite direction in the moving frame 9, completing a reciprocating rotation of the mounting frame 5. Through the above process, the impurities on the upper and lower surfaces of the steel plate are cleaned, and the impurities adhering to the steel plate are reduced, which affects the processing effect of the plate rolling machine body 1 on the steel plate.

[0031] like Figure 2 and Figure 4 and Figure 5After the steel plate is sucked onto the conveying roller 6 by the vacuum suction cup 22, a limiting member for aligning and limiting the steel plate on the conveying roller 6 is provided on the mounting frame 5. The limiting member includes a first limiting plate 29 and a second limiting plate 30 and a fixing bar 31 arranged on the left side of the top of the mounting frame 5. The first limiting plate 29 is horizontally located above each conveying roller 6 and is fixedly connected to the right side of the fixing bar 31. The second limiting plate 30 is horizontally located in the mounting frame 5 and contacts the right side in the mounting frame 5. A plurality of circular holes 32 are opened on the second limiting plate 30. One end of each conveying roller 6 passes through each circular hole 32 respectively. At this time, the second limit plate 30 is horizontally slidably connected to each conveying roller 6 through the circular hole 32, the second limit plate 30 corresponds to the first limit plate 29, and the second limit plate 30 is flush with the top of the first limit plate 29, and a hanging plate 33 is horizontally provided on the side of the second limit plate 30 close to the first limit plate 29, and the hanging plate 33 is located between two adjacent conveying rollers 6 and on one side of the vacuum suction cup 22. There are two hanging plates 33, and the two hanging plates 33 are arranged opposite to each other on one side of the second limit plate 30, and the bottom end of the second limit plate 30 between two adjacent conveying rollers 6 is flush with the bottom end of the hanging plate 33.

[0032] like Figure 2 and Figure 4 and Figure 5 , the process of the installation frame 5 completing a reciprocating rotation is first clockwise and then counterclockwise. When the installation frame 5 completes a reciprocating rotation, because the second limit plate 30 contacts the right side of the installation frame 5, and the process of the installation frame 5 completing a reciprocating rotation is first clockwise and then counterclockwise, the second limit plate 30 will not slide in the direction close to the first limit plate 29; When the vacuum suction cup 22 places the steel plate on the conveying roller 6, the steel plate on the conveying roller 6 will be located between the second limit plate 30 and the first limit plate 29, and then the rotating shaft of the servo motor 10 drives the installation frame 5 to rotate 45 degrees counterclockwise in the moving frame 9. At this time, the installation frame 5 is tilted, and the second limit plate 30 on the conveying roller 6 and the placed steel plate will be affected by gravity to approach the first limit plate 29 until one side of the steel plate on the conveying roller 6 contacts the first limit plate 29, and the side of the second limit plate 30 close to the first limit plate 29 contacts the steel plate. At this time, the suspension plate 33 is located below the steel plate and above the vacuum suction cup 22. At this time, the steel plate on the conveying roller 6 can be straightened by the first limit plate 29. After alignment, the mounting frame 5 rotates 45 degrees clockwise to make the mounting frame 5 horizontal, and then the piston rod of the electric cylinder 21 pushes the mounting plate 19 close to the conveying roller 6, so that the vacuum suction cup 22 moves upward until the vacuum suction cup 22 and the suspension plate 33 are in contact with and adsorbed with the bottom end of the second limit plate 30. At this time, there is a gap between the vacuum suction cup 22 and the bottom end of the steel plate. At this time, the aligned steel plate can be limited by the second limit plate 30 and the first limit plate 29, and then the steel plate between the second limit plate 30 and the first limit plate 29 is conveyed to the plate rolling machine body 1 for processing through the conveying roller 6. The second limit plate 30 and the first limit plate 29 reduce the tilt of the steel plate when the conveying roller 6 conveys the steel plate, thereby affecting the processing of the steel plate by the plate rolling machine body 1.

[0033] The working process of this device is as follows: In the first step, a pallet 4 with steel plates is placed on one side of the vertical plate 3 on the bottom plate 2 by a forklift from outside, so that the pallet 4 is located below the installation frame 5 .

[0034] In the second step, the servo motor 10 is turned on, and the rotating shaft of the servo motor 10 drives the installation frame 5 to rotate 180 degrees clockwise in the moving frame 9. During the rotation process, because the second limit plate 30 is in contact with the right side of the installation frame 5, when the rotating shaft of the servo motor 10 drives the installation frame 5 to rotate 180 degrees clockwise in the moving frame 9, the second limit plate 30 will not slide in the direction close to the first limit plate 29. After the installation frame 5 rotates 180 degrees clockwise in the moving frame 9, the servo motor 10 stops working (such as Figure 6 ).

[0035] In the third step, the first screw rod 17 is driven to rotate by the rotating shaft of the first drive motor 18, so that the first slide 14, the second slide 16, the movable frame 9 and the installation frame 5 move downward. When the movable frame 9 moves downward to a suitable position, the first drive motor 18 stops working. At this time, the bristles 25 on the outer horizontal plate 24 of the slide 23 will be located on the left side of the steel plate on the tray 4.

[0036] The fourth step is to turn on the second drive motor 28. The rotating shaft of the second drive motor 28 drives the second screw rod 27 to rotate, so that the slide 23 moves from the left side of the bottom end of the moving frame 9 to the right side along the width direction of the moving frame 9. At this time, the bristles 25 on the outer horizontal plate 24 of the slide 23 will contact the upper surface of the steel plate, thereby cleaning the impurities on the upper surface of the steel plate.

[0037] Step 5: The piston rod of the electric cylinder 21 pushes the mounting plate 19 close to the conveying roller 6, so that the vacuum suction cup 22 passes between two adjacent conveying rollers 6 and contacts the steel plate, and then the steel plate is sucked by the vacuum suction cup 22. After the vacuum suction cup 22 sucks the steel plate, the piston rod of the electric cylinder 21 pushes the mounting plate 19 away from the conveying roller 6, lifts the steel plate and aligns the steel plate sucked by the vacuum suction cup 22 with the slide 23, and then the electric cylinder 21 stops working. At this time, the steel plate is not in contact with the conveying roller 6, and then the moving frame 9 moves upward. Return to its original position, and then the rotating shaft of the second drive motor 28 drives the second screw rod 27 to rotate in the opposite direction, so that the slide 23 moves from the right side of the bottom end of the movable frame 9 to the left side. At this time, the steel plate sucked by the vacuum suction cup 22 will pass through the slide 23. At this time, the bristles 25 on the horizontal plate 24 inside the slide 23 will contact the lower surface of the steel plate, thereby cleaning the impurities on the lower surface of the steel plate. When the slide 23 slides, the slide 23, the horizontal plate 24 and the bristles 25 will not contact the first limit plate 29 and the second limit plate 30.

[0038] In the sixth step, the rotating shaft of the servo motor 10 drives the mounting frame 5 to rotate 180 degrees counterclockwise in the moving frame 9. At this time, the steel plate sucked by the vacuum suction cup 22 will be located above the conveying roller 6, and then the vacuum suction cup 22 will release the suction of the steel plate. After the release, the steel plate is still located on the vacuum suction cup 22, and then the piston rod of the electric cylinder 21 pushes the mounting plate 19 away from the conveying roller 6, so that the vacuum suction cup 22 passes between two adjacent conveying rollers 6 and moves to the bottom between the two conveying rollers 6. In this process, the steel plate on the vacuum suction cup 22 will be stably placed on the conveying roller 6 and located between the first limit plate 29 and the second limit plate 30.

[0039] In the seventh step, the rotating shaft of the servo motor 10 drives the horizontal mounting frame 5 to rotate 45 degrees counterclockwise in the moving frame 9, and the mounting frame 5 is tilted. At this time, because the second limit plate 30 is on the right side of the mounting frame 5, when the steel plate is located on the conveying roller 6 and the mounting frame 5 rotates 45 degrees counterclockwise in the moving frame 9, the second limit plate 30 on the conveying roller 6 and the placed steel plate will be affected by gravity to approach the first limit plate 29 until one side of the steel plate on the conveying roller 6 contacts the first limit plate 29, and the side of the second limit plate 30 close to the first limit plate 29 contacts the steel plate. At this time The hanging plate 33 will be located below the steel plate. At this time, the steel plate on the conveying roller 6 can be aligned by the first limit plate 29. After alignment, the mounting frame 5 rotates 45 degrees clockwise in the moving frame 9 to make the mounting frame 5 horizontal. Then the piston rod of the electric cylinder 21 pushes the mounting plate 19 close to the conveying roller 6, so that the vacuum suction cup 22 moves upward until the vacuum suction cup 22 contacts and adsorbs the bottom end of the hanging plate 33. At this time, the aligned steel plate can be limited by the second limit plate 30 and the first limit plate 29 to reduce the tilt of the steel plate when the conveying roller 6 conveys the steel plate.

[0040] In the eighth step, the conveying roller 6 conveys the steel plate between the second limiting plate 30 and the first limiting plate 29 to the plate rolling machine body 1 for processing.

[0041] In the ninth step, after the steel plate between the second limit plate 30 and the first limit plate 29 on the conveying roller 6 is completely conveyed to the plate rolling machine, the vacuum suction cup 22 releases the adsorption of the suspended plate 33, and then the second step, the third step, the fourth step, the fifth step, the sixth step, the seventh step, the eighth step, and the ninth step are repeated in sequence. When repeating the second step, because the installation frame 5 will rotate 180 degrees clockwise in the moving frame 9, the second limit plate 30 will be affected by gravity and move on the conveying roller 6 to the initial position in contact with the right side of the installation frame 5.

[0042] like Figure 7 and Figure 8 The hanging plate 33 can be replaced by a side plate 35 with a connecting hole 34 on the top. At this time, the connecting hole 34 on the side plate 35 corresponds to one of the vertical pipes 20 on the mounting plate 19 up and down. A vertical cylinder 36 is coaxially sleeved on the vertical pipe 20 corresponding to the connecting hole 34, and the vertical cylinder 36 is fixedly connected to the mounting plate 19. The vertical cylinder 36 is located below the vacuum suction cup 22. When the mounting plate 19 is close to the conveying roller 6, the vertical cylinder 36 is inserted into the connecting hole 34. At this time, the vacuum suction cup 22 corresponding to the connecting hole 34 passes through the connecting hole 34.

[0043] like Figure 7 and Figure 8 , the piston rod of the electric cylinder 21 pushes the mounting plate 19 close to the conveying roller 6, so that one end of the vertical cylinder 36 passes through the connecting hole 34. At this time, the vacuum suction cup 22 is located above the two adjacent conveying rollers 6, and then the rotating shaft of the servo motor 10 drives the mounting frame 5 to rotate 180 degrees in the moving frame 9, so that the vacuum suction cup 22 faces downward. At this time, because one end of the vertical cylinder 36 passes through the connecting hole 34, the second limit plate 30 can be limited by the cooperation between the vertical cylinder 36 and the connecting hole 34 on the side plate 35, so that the second limit plate 30 cannot move on the conveying roller 6 due to the rotation of the mounting frame 5. Through the above process, the mounting frame 5 can first rotate 180 degrees counterclockwise in the moving frame 9, and then rotate 180 degrees clockwise to complete a reciprocating rotation, or it can first rotate 180 degrees clockwise and then rotate 180 degrees counterclockwise to complete a reciprocating rotation. It is simple and convenient to use.

[0044] like Figure 2 and Figure 5 A ball 37 is provided on the side where the first limit plate 29 and the second limit plate 30 are close to each other, and each ball 37 is located above the conveying roller 6. The purpose of this arrangement is that the ball 37 can facilitate the steel plate to be conveyed from between the first limit plate 29 and the second limit plate 30 to the plate rolling machine body 1 through the conveying roller 6, which is simple and convenient to use.

[0045] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
