[0016] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0017] It should be noted that in the description of this specification, the terms "upper", "lower", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] like Figures 1 to 11 As shown, an embodiment of this utility model provides an automatic feeding device for an external grinding mill, including a hopper, a pushing assembly 5, and a bracket 6. The hopper is used to store workpieces to be processed. The hopper includes a storage bin 1, a feeding channel 2, and a discharge bin 3. The feeding channel 2 is inclined. The storage bin 1 and the discharge bin 3 are connected through the feeding channel 2. In the height direction, the storage bin 1 is higher than the discharge bin 3. The storage bin 1 is a box structure with an open top, used to store workpieces to be processed. The workpieces to be processed roll sequentially from the storage bin 1 into the discharge bin 3 through the inclined feeding channel 2 and wait to be pushed out to a set position for processing. In this embodiment, the set position refers to the processing position of the external grinding mill. The feeding assembly 5 includes a cone-shaped tip 501. The tip 501 can be driven to reciprocate in a single degree of freedom to push the workpiece from the hopper and press it against the set position. After the tip 501 is driven to move and press against the end of the workpiece, it pushes the workpiece away from the discharge bin 3 and into the set position until it is fixed and processing begins. After the tip 501 pushes the workpiece to the set position, it will press against the end of the workpiece until the workpiece is processed. This setting not only realizes automatic feeding but also ensures the stability of the workpiece during processing. Whether the workpiece is fixed at the set position by clamping or by pressing against both ends by another tip, the automatic feeding device of this utility model can be matched to realize the processing of the outer surface of the workpiece. The bracket 6 is supported at the bottom of the workpiece and can be driven to reciprocate between the hopper and the set position. In this embodiment, the bracket 6 is mainly used to lift the workpiece during the pushing process, providing support for the workpiece to ensure that the entire feeding and processing process can proceed stably and to prevent the workpiece from falling off during the pushing process by the top 501. In this embodiment, the bracket 6 can be adjusted to its specific support and lifting position according to the actual situation. It can be the front end of the workpiece (the front end here refers to the end near the set position) or the middle of the workpiece. It can be set as a single bracket or multiple brackets according to the actual situation. Multiple brackets can be controlled individually or linked together. The specific setting method can be adjusted and selected by those skilled in the art according to the actual situation, and will not be elaborated here.

[0019] In this embodiment, a limiting component 4 is also provided. The limiting component 4 is integrally installed in the hopper. The limiting component 4 includes a limiting rod 401, which is located at the connection between the feeding channel 2 and the discharge bin 3. The limiting rod 401 can be driven to insert into or remove from the hopper. In this embodiment, the limiting rod 401 is provided at the connection between the feeding channel 2 and the discharge bin 3 to restrict the workpiece from entering the discharge bin 3. This ensures that from the time the workpiece leaves the discharge bin 3 until processing is completed, the discharge bin 3 always contains only the currently processed workpiece, preventing subsequent workpieces to be processed from entering the discharge bin 3 prematurely and affecting the processing of the current workpiece.

[0020] In this embodiment, the feeding assembly 5 further includes a first driving component 502, which is installed in the discharge chamber 3 of the hopper. The first driving component 502 has a driving end, and the tip 501 is mounted on the driving end of the first driving component 502 in a manner that allows it to rotate around its own central axis. The first driving component 502 drives the tip 501 to reciprocate in a single degree of freedom. In this embodiment, the first driving component 502 is mainly used to drive the tip 501. Those skilled in the art can select, according to actual conditions, such as an electric push rod, a pneumatic push rod, or other driving components to drive the tip 501. In this embodiment, the first driving component 502 is an electric push rod, and the driving end refers to the moving end of the electric push rod. The tip 501 is mounted on the driving end by means of bearings, etc., to ensure that the tip 501 can rotate around its own axis so as to cooperate with the rotation of the workpiece for processing.

[0021] In this embodiment, the bracket 6 is equipped with multiple lifting rollers 601. The bracket 6 has an arc-shaped lifting part, and the multiple lifting rollers 601 are installed in a circular array on the lifting part. Each lifting roller 601 is arranged in a manner that allows it to rotate around its own axis. As shown in the figure, in this embodiment, the bracket 6 has an approximately "Y"-shaped structure, and its lifting rollers 601 are distributed in an array along the arc-shaped periphery of the lifting part. Each lifting roller 601 is exposed in the lifting part, and the multiple lifting rollers 601 are tangent to the same circumference. This arrangement ensures that each lifting roller 601 can support the workpiece, ensuring effective and stable support. At the same time, the rotation of the lifting rollers 601 will not affect the processing of the workpiece.

[0022] In this embodiment, the limiting component 4 further includes a second driving member 402 and a linkage plate 403. Multiple limiting rods 401 are provided, and each limiting rod 401 is connected to the second driving member 402 via the linkage plate 403. The linkage plate 403 can be driven by the second driving member 402 to perform a single-degree-of-freedom reciprocating motion. The multiple limiting rods 401 move synchronously to insert into or remove from the hopper. As shown in the figure, the second driving member 402 in this embodiment is also an electric push rod. Two limiting rods 401 are provided in this embodiment, and both limiting rods 401 are simultaneously connected to the second driving member 402 via the linkage plate 403. The second driving member 402 drives the linkage plate 403 to simultaneously move the two limiting rods 401, inserting them into the hopper to prevent subsequent workpieces from entering the discharge chamber 3, or removing them from the hopper to allow subsequent workpieces to enter the discharge chamber 3. In this embodiment, an mounting plate 404 is also provided, and the second driving member 402 is mounted on the outer wall of the hopper via the mounting plate 404. To facilitate the insertion of the limit rod 401, through holes are provided at corresponding positions on the mounting plate 404 and the hopper. During installation, it must be ensured that no matter how the limit rod 401 is moved, at least a part of it is inserted into the mounting plate 404. This will not affect the subsequent entry of the workpiece to be processed into the discharge bin 3, and will also prevent the limit rod 401 from being completely pulled out and affecting its normal operation.

[0023] In this embodiment, the discharge bin 3 is provided with a discharge port 301 for pushing the workpiece away from the discharge bin 3, and the opening direction of the discharge port 301 faces a set position. In this embodiment, a clearance port 302 for the tip 501 to enter is also provided on the opposite side of the discharge port 301 in the lateral direction. The first driving member 502 is detachably mounted on the hopper through the mounting rod corresponding to the position of the clearance port 302, and the tip 501 is located outside the discharge bin 3 when not in operation, while the bracket 6 is set at the position corresponding to the discharge port 301.

[0024] In this embodiment, a third driving component 8 and a driving rod 9 are also included. The third driving component 8 is installed on the bottom surface of the discharge chamber 3 of the hopper. The third driving component 8 is connected to the bracket 6 through the driving rod 9. In this embodiment, the third driving component 8 and the driving rod 9 are integrated electric push rods used to drive the bracket 6 to reciprocate. At the same time, this embodiment also provides a support lug 10. The support lug 10 is located on the bottom surface of the discharge chamber 3 at the position corresponding to the discharge port 301. The driving rod 9 passes through the support lug 10 and is connected to the bracket 6. The support lug 10 is provided with a limit key. The driving rod 9 is provided with a limit groove along its own axial direction. The limit key is inserted into the limit groove to limit the driving rod 9 in the circumferential direction. The limit component and the limit groove are inserted and matched to ensure that the driving rod 9 can only slide in the axial direction with a single degree of freedom, and there will be no circumferential rotational movement, which further improves the support stability of the bracket 6.

[0025] In this embodiment, multiple detachable support legs 7 are also provided on the bottom surface of the hopper to facilitate the installation of this utility model. Those skilled in the art can also choose whether to install the support legs 7 and the specific arrangement of the support legs 7 according to the actual situation. This is understandable to those skilled in the art and will not be elaborated here.
