[0007] Preferably, the feeding mechanism includes a baffle that is slidably fitted on a second support rod, a spring fitted on the second support rod below the baffle, a connecting rod threaded onto the second threaded rod, a guide rod fixedly installed on the top of the base plate, and the connecting rod slidably fitted on the guide rod. An inclined receiving block located above the baffle is fixedly installed on the side wall of the connecting rod, and a shock-absorbing pad is provided on the bottom surface of the receiving block near the storage compartment.

[0008] Preferably, the movable plate and the push rod are integrally formed.

[0009] Preferably, both the base plate and the baffle are "L" shaped.

[0013] Preferably, the bottom surface of the storage compartment is provided with a magnet layer and several ball bearings.

[0014] Preferably, it also includes an intelligent control system, which comprises a sensor module, a controller module, an actuator module, and a fault alarm module.

[0015] Preferably, the sensor module is installed in the discharge port of the storage hopper and in the groove of the auxiliary block to detect the remaining number of steel pipes in the storage hopper and the position of the steel pipes in the groove.

[0016] Preferably, the controller module (preferably a PLC controller) is fixedly installed on the side wall of the base plate and electrically connected to the sensor module, used to receive feedback signals from the sensor module and generate control commands;

It is simple and convenient to operate, provides uniform feeding, saves significant time, and improves the efficiency of the feeding process. The sensor module monitors the quantity and position of the steel pipes in real time, preventing feeding interruptions due to blockage or misalignment. The controller module precisely controls the servo motor's movement, improving the consistency and stability of the feeding interval. The fault alarm module responds promptly to abnormal situations (such as motor overload or sensor failure), preventing equipment damage or safety accidents, and improving the reliability and automation level of the device.

The auxiliary block has a baffle 91 located on one side of the groove, and an elastic plate 101 is arranged inside the groove, located at the bottom of the groove, with an arc-shaped structure, used to provide cushioning when the steel pipe is placed into the groove, reducing the impact on the steel pipe, and preventing the steel pipe from sliding during the pushing process. To further improve the cushioning, a buffer device (such as an airbag or hydraulic buffer) is provided inside the elastic plate to reduce the impact force when the steel pipe falls, extend the equipment life and protect the surface of the steel pipe. The auxiliary block 9 is rotatably connected to a first threaded rod 7. A fixing plate 5 is fixedly installed on the top of the base plate 1.

An inclined receiving block 3 located above the baffle 20 is fixedly mounted on the side wall of the connecting rod 15. A shock-absorbing pad is provided on the bottom surface of the receiving block near the storage bin to reduce the impact on the receiving block when the steel pipe slips.

[0034] As a technical improvement, the movable plate 8 and the push rod 10 are integrally formed, which facilitates the movement of the push rod 10 by the movable plate 8.

[0035] As a technical improvement, both the base plate 1 and the baffle 20 are L-shaped. The L-shaped base plate 1 is used to support the entire device, and the L-shaped baffle 20 is used to prevent the steel pipe from falling, ensuring that the steel pipe can slide smoothly into the groove 21.

[0036] As a technological improvement, the connecting rod 15 and the receiving block 3 are integrally formed.

[0037] As a technical improvement, two first mounting blocks 17 are symmetrically fixedly installed at the bottom of the higher end of the storage compartment 2, and a first support rod 4 is fixedly connected between the first mounting block 17 and the bottom plate 1. Two second mounting blocks 19 are symmetrically fixedly installed at the bottom of the lower end of the storage compartment 2, and a second support rod 16 is fixedly connected between the second mounting block 19 and the bottom plate 1.

[0038] As a technical improvement, the elastic strip is located above the push rod in an outwardly convex arc shape, and mounting blocks 102 are respectively provided on both sides of the arc-shaped elastic plate. The mounting blocks are fixed in the mounting groove 103 on the side wall of the groove to fix the elastic plate.

[0039] As a technical improvement, a magnet layer 22 and several balls 23 are provided on the bottom surface of the storage chamber, and a vibrator 24 is provided in the storage chamber to facilitate the sliding of the steel pipe in the storage chamber. The magnet layer is designed to be a soft magnet to attract debris, and the balls are designed to facilitate the sliding of the steel pipe on the inclined surface of the storage chamber.

[0040] As a technological improvement, it also includes an intelligent control system, which comprises a sensor module, a controller module, an actuator module, and a fault alarm module.

[0041] Preferably, the sensor module is installed in the discharge port of the storage hopper and in the groove of the auxiliary block to detect the remaining number of steel pipes in the storage hopper and the position of the steel pipes in the groove.

[0042] Preferably, the controller module (preferably a PLC controller) is fixedly installed on the side wall of the base plate and electrically connected to the sensor module, used to receive feedback signals from the sensor module and generate control commands;

[0043] Preferably, the actuator module includes a servo motor electrically connected to the controller module for executing commands from the controller module (such as controlling the start, stop, forward and reverse rotation, and speed of the servo motor).

[0044] Preferably, the fault alarm module is electrically connected to the controller module and includes a buzzer and an alarm indicator light, used to issue an audible and visual alarm signal and control the servo motor to stop when a blockage in the steel pipe, motor overload, or sensor malfunction is detected.

[0045] When this utility model is in use, the servo motor 6 is started, and the output shaft of the servo motor 6 drives the first threaded rod 7 to rotate. The rotation of the first threaded rod 7 causes the moving plate 8 to move closer to the servo motor 6. The movement of the moving plate 8 causes the push rod 10 to move closer to the servo motor 6. At the same time, the movement of the moving plate 8 causes the rack 11 to move away from the auxiliary block 9. Through the meshing of the rack 11 and the gear 12, the gear 12 is rotated. The rotation of the gear 12 causes the second threaded rod 13 to rotate. The rotation of the second threaded rod 13 causes the connecting rod 15 to move downward. The downward movement of the connecting rod 15 causes the receiving block 3 to move downward. The downward movement of the receiving block 3 causes the baffle 20 to move downward, and the spring 18 is compressed. In the retracted state, when the push rod 10 moves to the side of the auxiliary block 9 close to the servo motor 6, the receiving block 3 moves until its upper surface is flush with the inner surface of the lower end of the storage bin 2. The steel pipe in the storage bin 2 slides down the upper surface of the receiving block 3 into the groove 21 of the auxiliary block 9. At this time, the servo motor 6 causes the first threaded rod 7 to rotate in the other direction, and the moving plate 8 moves towards the auxiliary block 9. The moving plate 8 drives the push rod 10 to push the steel pipe in the groove 21 onto the conveyor belt or into the straightening machine. At the same time, the moving plate 8 causes the second threaded rod 13 to rotate in the other direction, and the receiving block 3 moves upward. The elastic force generated by the spring 18 causes the baffle 20 to return to its initial position so that the next feeding can be carried out.

[0046] The intelligent control system starts synchronously:

[0047] Sensor detection and feedback: The sensor module at the outlet of the storage hopper 2 detects the falling status of the steel pipe in real time, and the sensor module in the groove 21 detects whether the steel pipe falls into the groove 21 accurately; if the number of steel pipes in the storage hopper 2 is insufficient or the steel pipes in the groove 21 are not placed correctly, the sensor module sends an abnormal signal to the controller module.

[0048] Controller command generation: After receiving a normal signal, the controller module sends a start command to the servo motor 6 of the actuator module; if an abnormal signal is received, the controller module sends a command to the fault alarm module to trigger the buzzer and alarm indicator light, and controls the servo motor 6 to stop.

[0049] Actuator action: The output shaft of the servo motor 6 drives the first threaded rod 7 to rotate according to the controller command. The rotation of the first threaded rod 7 causes the moving plate 8 to move closer to the servo motor 6. The movement of the moving plate 8 causes the push rod 10 to move closer to the servo motor 6. At the same time, the rack 11 and the gear 12 mesh to rotate the second threaded rod 13. The connecting rod 15 drives the receiving block 3 to move downward. The baffle 20 compresses the spring 18. At this time, the steel pipe in the storage chamber 2 slides down the receiving block 3 into the groove 21.

[0050] Cycle control: When the sensor in the groove 21 detects that the steel pipe is in place, the controller module controls the servo motor 6 to reverse, the moving plate 8 drives the push rod 10 to push the steel pipe into the conveyor belt or straightening machine, and at the same time the second threaded rod 13 rotates in the opposite direction to reset the receiving block 3, and the spring 18 pushes the baffle 20 back to the initial position to complete one feeding cycle.

[0051] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
