[0021] The present invention will now be further described with reference to the accompanying drawings.

[0022] Please see Figures 1-5 The system includes a base plate 1, with two support plates 2 mounted on its upper surface. A rotating column 3 is rotatably connected between the two support plates 2. A motor 4 for driving the rotating column 3 is mounted on one side of one of the support plates 2. A placement groove 5 is formed on the inner wall of the rotating column 3, and a sealing mechanism 6 is provided on the outside of the placement groove 5. A pressing groove 7 is also formed on the inner wall of the rotating column 3, and a pressing mechanism 8 is provided inside the pressing groove 7. The rotating column 3 has pins at both ends for rotating within the support plates 2. The rotating column 3 is supported by the two support plates 2 and can also rotate. The motor 4... The outer casing is bolted to one side of the support plate 2. The output shaft of the motor 4 passes through the middle of the support plate 2 and is connected to the pin on the rotating column 3, thereby driving the rotating column 3 to rotate. The motor 4 is a servo motor, which can control the rotation angle of the output shaft. At the same time, the motor 4 is also equipped with auxiliary components such as brakes and gearboxes to facilitate precise control of the rotating column 3. This is existing technology and will not be described in detail here. There are four placement slots 5. With the center of the rotating column 3 as the center, each pair of adjacent placement slots 5 forms a 90-degree angle. The placement slots 5 are used to place steel bars.

[0023] The blocking mechanism 6 includes a fixed shaft 601, one end of which is fixedly connected to the rotating column 3. A stop rod 602 is rotatably connected to the inner wall of the fixed shaft 601. A drop block 603 is fixedly connected to the lower end of the stop rod 602. The stop rod 602 can rotate around the fixed shaft 601. Under the restriction of the fixed shaft 601, the stop rod 602 can only rotate and cannot tilt away from the rotating column 3. The drop block 603 is a solid iron support with a large weight. Under the action of the drop block 603 and gravity, the drop block 603 points downward toward the ground, thereby driving the stop rod 602 to rotate. When the rotating column 3 drives the stop rod 602 to a position away from the extrusion mechanism 8, it can block the steel rod in the placement groove 5 to prevent the steel rod from sliding out of the placement groove 5. When the rotating column 3 drives the stop rod 602 to move below the extrusion mechanism 8, the stop rod 602 opens, allowing the steel rod in the placement groove 5 to slide down.

[0024] The outer surface of the support plate 2 is fixedly provided with an inclined plate 9, and the middle portion of the rotating column 3 is provided with a processing groove 12, the inclined plate 9 has a certain inclination, when the rotating column 3 drives the steel bar to rotate, it can be separated from the placing groove 5 and fall to the bottom plate 1 under the extrusion of the inclined plate 9, the processing groove 12 is in the shape of a circular ring, so that the middle portion of the rotating column 3 is concave to the inside, and generally cuts or punches the steel bar above for processing.

[0025] The extrusion mechanism 8 comprises a support rod 801, the lower surface of the support rod 801 is fixedly connected with a fixed plate 10, the lower part of the fixed plate 10 is fixedly connected with a fixed rod 11, the lower end of the fixed rod 11 is fixedly connected with the bottom plate 1, the fixed plate 10 is used to support the fixed rod 11, the number of the fixed rod 11 is two, the fixed plate 10 is located between the two fixed rods 11, and a processing tool such as a cutting device can be installed at the position, which is used for processing the steel bar on the top, a storage space is formed between the fixed rod 11 and the support plate 602, the steel bar processed and fallen is dropped in the storage space, so as to collect the steel bar and take it out in a concentrated manner.

[0026] The upper end of the support rod 801 is hingedly connected with a movable plate 802, one end of the movable plate 802 is fixedly provided with an extrusion rod 803, the outer surface of the extrusion rod 803 is slidably connected with the pressing groove 7, when the extrusion rod 803 enters the inside of the pressing groove 7 downward, the upper steel bar is extruded at the same time, so as to be fixed, thereby facilitating production.

[0027] The upper surface of the fixed plate 10 is fixedly provided with a telescopic rod 804, the telescopic end of the telescopic rod 804 is in contact with the movable plate 802, the telescopic rod 804 is electrically telescopic, when the telescopic rod 804 is elongated, the movable plate 802 can be extruded upward, so that the extrusion rod 803 extrudes the steel bar, when the telescopic rod 804 is shortened, the extrusion of the steel bar can be released, and the telescopic end of the telescopic rod 804 can be separated from the movable plate 802.

[0028] The motor 4 and the telescopic rod 804 in the application are common electrical equipment in the prior art, and the model or internal structure thereof will not be described in detail, and they can also be replaced by other power sources.

[0029] In use, this utility model works as follows: Rotating the stop bar 602 away from the fixed rod 11 opens the placement groove 5, allowing the steel rod to be placed inside. Releasing the stop bar 602 causes it to stop the steel rod in the placement groove 5 under gravity, preventing it from falling out. The motor 4 drives the rotating column 3 to rotate 90 degrees, moving the steel rod to the upper end. The pressing mechanism 8 then presses the steel rod from above, fixing it for easier processing. After processing, the rotating column 3 rotates another 90 degrees, moving the processed steel rod closer to the fixed rod 11. Under gravity, the stop bar 2 opens, and the steel rod falls to the bottom of the fixed rod 11 under the combined force of the inclined plate 9 and the steel rod's own weight. This process is repeated for reuse. During the processing of the upper steel rod, unprocessed steel rods are installed on one side, while processed ones automatically detach on the other side, facilitating installation and disassembly and saving time.
