[0026] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] like Figures 1 to 3As shown, this utility model discloses an automatic powder-spreading device, comprising a powder-spreading frame 1, a conveying mechanism 2, a powder-discharging mechanism 3, a powder-receiving mechanism 4, and a powder-spreading mechanism 5. The conveying mechanism 2 is mounted on the powder-spreading frame 1. The powder-discharging mechanism 3 is mounted on the powder-spreading frame 1 and includes a hopper 31. The powder-receiving mechanism 4 includes a receiving and weighing scoop 41 and a connecting bracket 42. The connecting bracket 42 is mounted on the powder-spreading frame 1, and the receiving and weighing scoop 41 is rotatably mounted on the connecting bracket 42, located directly below the discharge port 311 of the hopper 31. The powder-spreading mechanism 5 includes a powder-spreading mounting plate 51, a powder-spreading movable seat 52, and a powder-spreading... The powder cup 53, the cup opening switch assembly 54, the vibrating plate 55, and the vibrating funnel 56 are arranged together. The powder spreading mounting plate 51 is set on the powder spreading frame 1. The powder spreading moving seat 52 is movable along the forward and reverse directions of the conveying mechanism 2 and is set on the powder spreading mounting plate 51. The powder spreading cup 53 is set on the powder spreading moving seat 52 and can be moved to the position directly below the receiving weighing spoon 41. The cup opening switch assembly 54 is set on the powder spreading moving seat 52 and can open or close the lower discharge port of the powder spreading cup 53. The vibrating plate 55 is set on the powder spreading moving seat 52. The vibrating funnel 56 is set on the vibrating plate 55 and is located directly below the powder spreading cup 53.

[0028] Thus, in use, the automatic powder-spreading device of this utility model involves the conveying mechanism 2 conveying multiple core materials. The material in the feeding hopper 31 falls onto the receiving weighing scoop 41 through the feeding port 311. When the material in the receiving weighing scoop 41 reaches the specified weight, the feeding hopper 31 stops discharging. Then, the powder-spreading moving seat 52 moves, causing a powder-spreading cup 53 to move below the receiving weighing scoop 41. The receiving weighing scoop 41 rotates to transfer the material in the receiving weighing scoop 41 into the powder-spreading cup 53. The above steps are repeated until each powder-spreading cup 53 contains a fixed amount of material. Finally, the powder-spreading moving seat 52 moves above the core materials, and the cup opening switch assembly 54 drives the material in the powder-spreading cup 53 to fall onto the vibrating funnel 56. The vibrating funnel 56 vibrates to spread the material relatively evenly onto the core materials. The powder-spreading moving seat 52 moves above different core materials to spread powder on each core material.

[0029] Optionally, the conveying mechanism 2 includes a first belt roller 21, a second belt roller 22, and a conveyor belt 23. The first belt roller 21 is rotatably mounted on one side of the powder spreading frame 1, and the second belt roller 22 is rotatably mounted on the other side of the powder spreading frame 1. The conveyor belt 23 is connected to the first belt roller 21 and the second belt roller 22. The first belt roller 21 can be connected to a motor and driven to rotate by the motor. The first belt roller 21 drives the second belt roller 22 to rotate via the conveyor belt 23, thereby enabling the conveyor belt 23 to transport the core material.

[0030] Furthermore, the powder feeding mechanism 3 also includes a hopper 32, an elevator 33, and a mixer 34. One end of the elevator 33 is connected to the hopper 32, and the other end of the feeding hopper 31 is connected to the elevator 33. The mixer 34 is installed on the powder spreading frame 1 and is connected to the feeding hopper 31 to mix the material in the feeding hopper 31.

[0031] In use, the material is loaded into the hopper 32. The material in the hopper 32 is transferred to the mixer 34 by the elevator 33. The mixer 34 mixes the material evenly. Finally, the material falls onto the receiving weighing scoop 41. When the material on the receiving weighing scoop 41 reaches the predetermined weight value, the control system controls the feeding hopper 31 to stop feeding, and the receiving weighing scoop 41 rotates to transfer the material into the powder spreading cup 53.

[0032] In this embodiment, the connecting bracket 42 includes a vertical plate 421 and a flat plate 422. One end of the vertical plate 421 is fixed to the powder spreading frame 1, and the flat plate 422 is connected to the other end of the vertical plate 421. A rotary cylinder 43 is installed on the flat plate 422. The rotary cylinder 43 is connected to the receiving and weighing scoop 41 and drives the receiving and weighing scoop 41 to rotate. By setting the rotary cylinder 43, the receiving and weighing scoop 41 can be rotated at a certain angle, thereby transferring the material in the receiving and weighing scoop 41 to the powder spreading cup 53.

[0033] The powder receiving mechanism 4 is mounted in the middle of the powder spreading frame 1. The powder spreading mechanism 5 includes a first powder spreading mechanism 5a and a second powder spreading mechanism 5b. The first powder spreading mechanism 5a is located on one side of the powder receiving mechanism 4, and the second powder spreading mechanism 5b is located on the other side of the powder receiving mechanism 4. By setting the first powder spreading mechanism 5a and the second powder spreading mechanism 5b, the first powder spreading mechanism 5a spreads powder onto the core material located on one side of the connecting bracket 42, while the second powder spreading mechanism 5b spreads powder onto the core material located on the other side of the connecting bracket 42. When the first powder spreading mechanism 5a spreads powder onto the core material located on one side of the connecting bracket 42, the second powder spreading mechanism 5b cooperates with the receiving and weighing scoop 41 to collect the powder. When the second powder spreading mechanism 5b spreads powder onto the core material located on the other side of the connecting bracket 42, the first powder spreading mechanism 5a cooperates with the receiving and weighing scoop 41 to collect the powder. In this way, the first powder spreading mechanism 5a and the second powder spreading mechanism 5b alternately cooperate with the receiving and weighing scoop 41, improving the overall powder spreading efficiency.

[0034] Furthermore, a linear rack 511 is provided on the powder-spreading mounting plate 51, and a drive motor 521 is provided on the powder-spreading moving seat 52. The drive motor 521 is connected to a drive wheel, and the drive wheel meshes with the linear rack 511. When the powder-spreading moving seat 52 needs to move, the drive motor 521 drives the drive wheel to rotate. Since the drive wheel meshes with the linear rack 511, the rotation of the drive wheel realizes the movement of the powder-spreading moving seat 52. The powder-spreading mounting plate 51 is provided with a slide rail, and the powder-spreading moving seat 52 is provided with a slider that slides along the slide rail. Thus, when the powder-spreading moving seat 52 moves, the slider slides along the slide rail, making the movement of the powder-spreading moving seat 52 smoother.

[0035] In this embodiment, multiple powder-spreading cups 53 are arranged side-by-side on the powder-spreading moving base 52. The upper end of each powder-spreading cup 53 is an upper feed port 531, and the lower end is a lower discharge port. The cup opening switch assembly 54 includes a drive cylinder 541 and a baffle 542. The drive cylinder 541 is fixed to the powder-spreading moving base 52, and the baffle 542 is connected to and driven by the drive cylinder 541 to reciprocate, thereby blocking or not blocking the lower discharge port of the powder-spreading cup 53. For example, the first powder-sprinkling mechanism 5a can be equipped with three powder-sprinkling cups 53, and the second powder-sprinkling mechanism 5b can also be equipped with three powder-sprinkling cups 53. In the initial state, the baffle 542 blocks the lower discharge port, and the receiving and weighing scoop 41 transfers the material from the upper feed port 531 to the powder-sprinkling cup 53. When it is necessary to sprinkle the material onto the core material, the baffle 542 leaves the lower discharge port under the action of the driving cylinder 541, thereby realizing the sprinkling of the material onto the core material.

[0036] In this embodiment, a pneumatic vibrator is installed at the bottom of the vibrating plate 55, and a filter screen is installed at the bottom of the vibrating funnel 56. The pneumatic vibrator drives the vibrating plate 55 to vibrate, thereby enabling the material in the vibrating funnel 56 to be more evenly distributed from the filter screen onto the core material.

[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
