[0002] The three-in-one feeding machine is an automated device optimized by integrating three functions of uncoiling, leveling, and feeding into one machine, and is used for automatically feeding metal coil materials, leveling to remove internal stress, and then servo-feeding them into processing equipment such as punching presses for automatic stamping processing.

[0003] In the Chinese patent with the publication number CN204892776U, a thick plate type three-in-one feeding machine is disclosed. Its technical solution is as follows: It includes a chassis, a loading cart, a feeding mechanism, and a leveling and feeding mechanism. The feeding mechanism is arranged on the chassis through a bracket, the leveling and feeding mechanism is arranged on the chassis at a position corresponding to one side of the feeding mechanism, and the loading trolley is arranged on the chassis at a position corresponding to the lower part of the feeding mechanism. The feeding mechanism includes an unwinding motor, a reducer, a supporting roller, and a braking device. The supporting roller is horizontally arranged on the bracket through a bearing assembly, the braking device is arranged at one end position of the supporting roller on one side wall of the bracket, the unwinding motor is located at the top of the bracket and is connected to the input end of the reducer, and the output end of the reducer is connected to the supporting roller through a transmission component. A supporting arm is arranged on the bracket at a position corresponding to the lower part of the supporting roller. However, there are still the following disadvantages: When using the loading cart to place the steel coil on the feeding mechanism, the supporting arm needs to be lifted to prevent the steel coil from colliding with it. However, this feeding machine is not provided with a device for lifting the supporting arm, so it needs to be lifted manually, which is time-consuming and laborious and affects work efficiency.

[0004] In the Chinese patent with the publication number CN213728983U, a numerical control three-in-one feeding machine is disclosed. Its technical solution is as follows: It includes a base, a material loop control mechanism, a feeding mechanism, and a leveling and feeding mechanism. The material loop control mechanism includes a pressure arm and a supporting arm. The pressure arm and the supporting arm are respectively installed above and below the material loop control mechanism. The feeding mechanism includes a telescopic drum, a coil, a hydraulic device, a motor 1, a stop arm, and a loading trolley. A support seat is arranged above the loading trolley. The front telescopic end of the hydraulic device is connected to the back of the motor 1, and the front output end of the motor 1 is connected to the stop arm. However, there are still the following disadvantages: The pressure arm and the supporting arm of this feeding machine cannot move. Therefore, when processing a steel coil with a larger diameter, the steel coil may collide with the pressure arm and the supporting arm. Therefore, the processing of the steel coil has limitations.

[0039] The second limiting component includes two limiting rods 3. A first connecting block 2 is rotatably connected to the housing 1.

The output shaft of the first motor 4 passes through the first connecting block 2 and is fixedly connected to a bidirectional screw 39. Both ends of the bidirectional screw 39 are threadedly connected with sliders 20, and both sliders 20 are slidably connected to the first connecting block 2. One end of the first connecting block 2 is fixedly connected to a square shaft 40. The square shaft 40 passes through the two sliders 20 and is slidably connected to the sliders 20.

[0040] Fixedly connected to the inner wall of the housing 1 are a fourth motor 22 and a fifth motor 30. The output shaft of the fourth motor 22 passes through the housing 1 and is fixedly connected to a third connecting shaft 52. The third connecting shaft 52 passes through two connecting rods 5 and is fixedly connected to the connecting rods 5. The output shaft of the fifth motor 30 passes through the housing 1 and is fixedly connected to a first connecting block 2.

[0041] Working principle: In summary, in the initial state, the trolley 10 is located on the side of the base 19 away from the housing 1.

[0042] When using this device, the operator first places the steel coil on the top surface of the V-groove frame 7, and then starts the hydraulic rod 45. The telescopic shaft of the hydraulic rod 45 extends and pushes the V-groove frame 7 to move upward. The V-groove frame 7 drives the steel coil to move upward. When the center of the steel coil coincides with the central axis of the main shaft 41, the operator turns off the hydraulic rod 45.

[0043] The operator starts the fifth motor 30. The output shaft of the fifth motor 30 drives the first connecting block 2 to rotate clockwise. The first connecting block 2 drives the corresponding limiting rods 3 to rotate around the central axis of the output shaft of the fifth motor 30 through two sliders 20. When both limiting rods 3 rotate to face upward, the operator turns off the fifth motor 30.

[0044] Then the operator starts the second motor 15. The output shaft of the second motor 15 drives the third pulley 46 to rotate. The third pulley 46 drives the first pulley 13 to rotate through the first transmission belt 14. The first pulley 13 drives the corresponding rotating shaft to rotate. The rotating shaft drives the corresponding two wheels 12 to roll along the guide rail 18, thereby driving the trolley 10 to move towards the housing 1, and the trolley 10 transports the steel coil to the feeding mechanism.

[0045] During the movement of the trolley 10, one end of the ejector rod 23 cooperates with the rack 38 and pushes the rack 38 to move. During the movement of the rack 38, it pushes the sliding shaft 33 to slide in the third connecting block 26 and compresses the spring 27. At the same time, the rack 38 drives the gear 28 to rotate, the gear 28 drives the worm 32 to rotate, the worm 32 drives the worm wheel 35 to rotate, the worm wheel 35 drives the second pulley 36 to rotate through the first rotating rod, the second pulley 36 drives the fifth pulley 53 to rotate through the second transmission belt 37, the fifth pulley 53 drives the first connecting shaft 9 to rotate, the first connecting shaft 9 rotates clockwise, and drives the supporting arm 8 to rotate clockwise around the central axis of the first connecting shaft 9. The rotation of the supporting arm 8 can prevent the steel coil from colliding with the supporting arm 8.

[0046] When the trolley 10 transports the steel coil onto the unwinding mechanism, the operator turns off the second motor 15. Then the operator starts the fifth motor 30, causing the output shaft of the fifth motor 30 to rotate in the reverse direction. The output shaft of the fifth motor 30 drives the first connecting block 2 to rotate counterclockwise. The first connecting block 2 drives the corresponding limiting rods 3 to rotate counterclockwise around the central axis of the output shaft of the fifth motor 30 through two sliders 20. When the two limiting rods 3 rotate to the horizontal direction, the operator turns off the fifth motor 30. At this time, the steel coil is located between the two limiting rods 3.

[0047] Then the operator starts the first motor 4. The output shaft of the first motor 4 drives the bidirectional screw 39 to rotate. The bidirectional screw 39 drives the two sliders 20 to move closer to each other, and at the same time drives the two limiting rods 3 to move closer to each other. After the two limiting rods 3 limit the width of the steel coil, the operator turns off the first motor 4.

[0048] Then the operator starts four electric push rods 43. The four electric push rods 43 push the corresponding top blocks 42 to move, so that the arc surfaces on the outside of the top blocks 42 are fitted with the inner wall of the steel coil.

[0049] Then the operator starts the second motor 15, causing the output shaft of the second motor 15 to rotate in the reverse direction, and driving the third pulley 46 to rotate in the reverse direction. The third pulley 46 drives the first pulley 13 to rotate in the reverse direction through the first transmission belt 14. The first pulley 13 drives the corresponding two wheels 12 to roll in the reverse direction along the guide rail 18 through the rotating shaft. The trolley 10 moves away from the housing 1 along the guide rail 18 and finally moves to one end of the base 19.

[0050] During the movement of the trolley 10, the ejector rod 23 gradually disengages from the rack 38. The spring 27 releases the stored elastic potential energy, pushing the sliding shaft 33 and the rack 38 towards the trolley 10, and finally resetting the spring 27.

[0051] During the movement of the rack 38, the rack 38 drives the gear 28 to rotate in the reverse direction. The gear 28 drives the worm 32 to rotate in the reverse direction. The worm 32 drives the worm gear 35 to rotate in the reverse direction. The worm gear 35 drives the second pulley 36 to rotate in the reverse direction through the first rotating rod. The second pulley 36 drives the fifth pulley 53 to rotate in the reverse direction through the second transmission belt 37. The fifth pulley 53 drives the first connecting shaft 9 to rotate in the reverse direction. The first connecting shaft 9 drives the supporting arm 8 to rotate in the reverse direction around the central axis of the first connecting shaft 9.

[0052] Then the operator starts the fourth motor 22. The output shaft of the fourth motor 22 drives the third connecting shaft 52 to rotate clockwise, and drives the pressure wheel 6 to rotate clockwise around the central axis of the third connecting shaft 52 through the connecting rod 5, so that the pressure wheel 6 is fitted with the steel coil. Then the operator turns off the fourth motor 22.

[0053] Subsequently, the personnel start the third motor 21. The output shaft of the third motor 21 drives the connecting rod 29 to rotate counterclockwise, and the connecting rod 29 drives the main shaft 41 to rotate counterclockwise. The main shaft 41 drives the corresponding top block 42 to rotate counterclockwise around the central axis of the main shaft 41 through four electric push rods 43, and the top block 42 drives the steel coil to rotate counterclockwise.

[0054] While the steel coil rotates counterclockwise, it starts to discharge materials layer by layer. The pressing wheel 6 rolls on the surface of the steel coil, pressing the steel coil to prevent it from being overly loose. The discharged coil material cooperates with the rollers on the material supporting arm 8, and the rollers roll on one side of the coil material. Finally, the coil material enters the flattening machine main body 17, and the flattening machine main body 17 flattens the coil material. Embodiment 2

[0055] This embodiment only introduces the structure different from that of Embodiment 1.

[0056] As Figures 9 - 10 shown, a second rotating rod is rotatably connected to the inner wall of the housing 1. One end of the second rotating rod passes through the housing 1 and is fixedly connected to the first connecting block 2. A fourth belt pulley 51 is sleeved on the second rotating rod, and a third transmission belt 50 is sleeved on the fourth belt pulley 51 and the fifth belt pulley 53. A fixing block is fixedly connected between the ends of the two connecting rods 5 far from the pressing wheel 6. One end of the fixing block is fixedly connected to a third rotating rod. The third rotating rod passes through the housing 1 and is rotatably connected to the housing 1. A torsion spring 49 is sleeved on the third rotating rod. One end of the torsion spring 49 is fixedly connected to the third rotating rod, and the other end is fixedly connected to the inner wall of the housing 1. A fixing plate 48 is fixedly connected to one side of the housing 1. A limiting pin 47 is slidably connected in the fixing plate 48, and a limiting hole matching with the limiting pin 47 is formed in the fixing block.

[0057] Working principle: In summary, in the initial state, the limiting pin 47 cooperates with the limiting hole.

[0058] During the process of the trolley 10 approaching the housing 1, one end of the ejector rod 23 will cooperate with the rack 38 and push the rack 38 to move. During the movement of the rack 38, it pushes the sliding shaft 33 to slide in the third connecting block 26 and compresses the spring 27. At the same time, the rack 38 drives the gear 28 to rotate, the gear 28 drives the worm 32 to rotate, the worm 32 drives the worm wheel 35 to rotate, the worm wheel 35 drives the second belt pulley 36 to rotate through the first rotating rod, the second belt pulley 36 drives the fifth belt pulley 53 to rotate through the second transmission belt 37, the fifth belt pulley 53 drives the first connecting shaft 9 to rotate, the first connecting shaft 9 rotates clockwise, and drives the material supporting arm 8 to rotate clockwise around the central axis of the first connecting shaft 9.

[0059] While the fifth pulley 53 rotates, it drives the fourth pulley 51 to rotate through the third transmission belt 50. The fourth pulley 51 drives the second rotating rod to rotate clockwise, and the second rotating rod drives the first connecting block 2 to rotate clockwise. The first connecting block 2 drives the corresponding limiting rod 3 to rotate clockwise around the central axis of the second rotating rod through two sliders 20. After the trolley 10 stops moving, the fourth pulley 51 and the fifth pulley 53 also stop rotating.

[0060] When the trolley 10 moves away from the housing 1, the ejector rod 23 gradually disengages from the rack 38. The spring 27 releases the stored elastic potential energy, pushes the sliding shaft 33 and the rack 38 towards the trolley 10, and finally resets the spring 27.

[0061] During the movement of the rack 38, the rack 38 drives the gear 28 to rotate in the reverse direction, the gear 28 drives the worm 32 to rotate in the reverse direction, and the worm 32 drives the worm gear 35 to rotate in the reverse direction. The worm gear 35 drives the second pulley 36 to rotate in the reverse direction through the first rotating rod, and the second pulley 36 drives the fifth pulley 53 to rotate in the reverse direction through the second transmission belt 37. The fifth pulley 53 drives the first connecting shaft 9 to rotate in the reverse direction, and the first connecting shaft 9 drives the material supporting arm 8 to rotate in the reverse direction around the central axis of the first connecting shaft 9.

[0062] The fifth pulley 53 drives the fourth pulley 51 to rotate in the reverse direction through the third transmission belt 50. The fourth pulley 51 drives the second rotating rod to rotate counterclockwise, the second rotating rod drives the first connecting block 2 to rotate counterclockwise, and the first connecting block 2 drives the corresponding limiting rod 3 to rotate counterclockwise around the central axis of the second rotating rod through two sliders 20. After the ejector rod 23 is completely disengaged from the rack 38, the fourth pulley 51 and the fifth pulley 53 stop rotating. At this time, the steel coil is located between the two limiting rods 3.

[0063] When starting to feed the material, the operator pulls out the limiting pin 47 to disengage the limiting pin 47 from the limiting hole on the rectangular block. The torsion spring 49 releases the stored elastic potential energy and drives the rectangular block to rotate clockwise. The rectangular block drives the pressure wheel 6 to rotate clockwise around the central axis of the rectangular block through two connecting rods 5, so that the pressure wheel 6 cooperates with the steel coil to prevent the steel coil from being too loose.

[0064] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
