[0020] This utility model provides a stepping mill feeder suitable for centerless grinding machines: it includes a frame 1 and a feeding assembly 22. The feeding assembly 22 includes an electrical control box 2, a stepping synchronous belt feeder 3, a circular belt take-up machine 4, a circular belt take-up support 5, a circular belt drive motor 6, a synchronous belt drive motor 7, a synchronous belt with baffles 8, a synchronous belt feed sensor 9, a synchronous belt pulley positioning key 10, a synchronous belt speed controller 11, a circular belt left / right adjustment handwheel 12, a circular belt height adjustment seat 13, a circular belt front / back adjustment handwheel 14, a circular belt 15, a support mounting plate 16, a feeding transition plate 17, an anti-overshoot baffle plate 18, a circular belt feed sensor 19, a circular belt speed controller 20, and a mounting base 21.

[0021] In this embodiment, the stepping synchronous feeder 3 is connected to the frame 1 and located at the top of the frame 1. The circular strip receiving support 5 is disposed on one side of the frame 1. The support mounting plate 16 is fixedly connected to the circular strip receiving support 5 and located on one side of the circular strip receiving support 5.

The top of the frame 1 is equipped with a water receiving plate and a water return port. The internal electrical control cabinet has an independent waterproof partition to ensure that electrical components and the environment are not affected by water ingress during use. The stepping synchronous belt feeder 3 and the circular belt take-up machine 4 are combined at a 90-degree angle to achieve stepping feeding. The stepping synchronous feeder 3 separates and conveys parts, which are then fed into the circular belt take-up machine 4 for further stable transmission. This achieves uniform feeding of one workpiece per unit time, with cyclic feeding, adaptable to diameters... Workpieces with a length between 20-300mm are automatically fed into a centerless grinder for grinding, solving the problem of unstable automated feeding of short workpieces that need grinding by existing stepper feeders.

[0022] The stepping synchronous feeder 3 includes a synchronous belt drive motor 7, a synchronous belt with baffles 8, a synchronous shaft, and synchronous belt positioning wheels. Two synchronous shafts are mounted at both ends of the top of the frame 1. The synchronous belt drive motor 7 is mounted on the frame 1, and its output end is fixedly connected to the synchronous shafts. The synchronous belt positioning wheels are mounted on the synchronous shafts, and the synchronous belt with baffles 8 is located outside the positioning wheels. The synchronous shaft is driven to rotate by the synchronous belt drive motor 7, causing the synchronous belt with baffles 8 to move. A workpiece can be placed between each of the two baffles of the synchronous belt with baffles 8, thus separating the workpieces and preventing them from entering during transport. The device uses a T10 type 30mm wide synchronous belt 8 with baffles as the conveying medium. The double-row synchronous belt and the synchronous belt positioning wheel are both processed by double-row one-time forming and two-stage cutting to ensure that the synchronous belt and synchronous wheel can run synchronously. The synchronous belt positioning wheel is installed on the synchronous shaft by positioning key. When using the device, the workpiece is first placed manually from one end near the circular belt take-up machine 4 into the baffles of the stepping synchronous belt feeder 3 between the baffles of the synchronous belt 8. One workpiece is placed between every two baffles until the machine is full. The device is then started. After the synchronous belt material sensor 9 detects the presence of material, the synchronous belt drive motor 7 starts.

[0023] Secondly, the circular belt take-up machine 4 includes an adjusting component, a mounting base 21, a circular belt drive motor 6, a feeding transition plate 17, an anti-overshoot baffle plate 18, and a circular belt 15. The adjusting component is disposed on the top of the circular belt take-up support 5, and the mounting base 21 is mounted on the adjusting component. The circular belt 15 is rotatably connected to the mounting base 21 and located inside the mounting base 21. The output end of the circular belt drive motor 6 is connected to the circular belt 15 via a shaft and is connected to the circular belt take-up support 5, and is located on the top of the circular belt take-up support 5. The feeding transition plate 17 and the anti-overshoot baffle plate 18 are both mounted on the top of the mounting base 21, using a diameter... The circular belt 15 is the conveying medium. The circular belt 15 is mounted on the mounting base 21 via a circular belt pulley. The circular belt pulley uses a separate double-row sprocket to control the distance between the two circular belts 15 to accommodate workpieces of different sizes. The circular belt drive motor 6 is used as the output power to drive the circular belt 15. The workpiece entering the circular belt take-up machine 4 falls above the feeding transition plate 17 and continues to roll down until it hits the anti-overshoot blocking plate 18. Under the action of gravity, the workpiece falls between the two circular belts 15 of the circular belt take-up machine 4, sending the workpiece into the grinding area. When the workpiece passes the circular belt material sensor 19, the synchronous belt drive motor 7 cannot run. When the circular belt material sensor 19 has no signal and the synchronous belt material sensor 9 has a signal, the synchronous belt drive motor 7 can run normally.

[0024] Furthermore, the adjustment components include a left-right adjustment handwheel 12 mechanism, a round belt height adjustment seat 13, and a front-back adjustment handwheel 14 mechanism. The left-right adjustment handwheel 12 mechanism is connected to the round belt take-up support 5 and is located on top of the round belt take-up support 5. The round belt height adjustment seat 13 is located on top of the left-right adjustment handwheel 12 mechanism, and the front-back adjustment handwheel 14 mechanism is located on top of the round belt height adjustment seat 13. The mounting base 21 is located on the front-back adjustment handwheel 14 mechanism. The left-right adjustment handwheel 12 mechanism uses a double-layer plate superposition and handwheel cooperation to achieve left-right adjustment. The round belt height adjustment seat 13 uses two sets of M80×1.5 trapezoidal threaded adjustment rods to support the line body simultaneously, achieving adjustable height and adjustable tilt. The front-back adjustment handwheel 14 uses a gear and rack cooperation handwheel adjustment to achieve front-back adjustment of the line body, meeting the requirement that the line body can move back and forth.

[0025] Finally, the feeding assembly 22 also includes a circular belt speed regulator 20 and a synchronous belt speed regulator 11. The synchronous belt speed regulator 11 is located at the connection between the synchronous shaft and the synchronous belt drive motor 7. The circular belt speed regulator 20 is located between the circular belt drive motor 6 and the circular belt 15. The circular belt speed regulator 20 is configured to adjust the conveying speed of the circular belt 15 to match the grinding speed as needed. The synchronous belt speed regulator 11 is configured to adjust the speed of the baffle synchronous belt 8 to match the speed of the circular belt 15 as needed.

[0026] In a walking beam feeder for a centerless grinder according to this utility model, the circular belt receiving support 5 is matched with the front mounting position of the centerless grinder. The dimensions of the support mounting plate 16 can be modified according to actual needs for different centerless grinders. The frame 1 is assembled from 50×50 aluminum profiles and corner brackets, making it easy to process and install, aesthetically pleasing, and easy to clean and maintain. The electrical control box 2 is installed below it, and the electrical control box 2 is equipped with a circuit control device for controlling the operation of the device. A [missing information - likely a device or component] is installed on the top of the frame 1. The system includes a water receiving plate and return port, and an internal electrical control cabinet with an independent waterproof partition to ensure that electrical components and the environment are not affected by water ingress during use.
