[0001] The utility model relates to the technical field of grinding in porcelain preparation, and particularly relates to a ball mill for facilitating feeding in porcelain production. Background Art

[0002] In the process of porcelain production, it is necessary to fully grind the prepared raw materials. In the prior art, a ball mill is usually used to grind the raw materials for wear resistance.

[0003] The existing ball mill is driven to rotate by driving devices such as motors, so that the internal grinding balls and raw materials are fully squeezed and ground to obtain powdery raw materials. The existing ball mill drum is usually provided with a feed inlet on the outer wall of its cylinder to achieve feeding or discharging.

[0004] However, in the actual production process, multiple feedings are required. The existing ball mill needs to stop rotating first and then open the feed inlet to achieve feeding. This not only affects the grinding efficiency, but also affects the rotation driving device of the ball mill and reduces its service life. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a ball mill for facilitating feeding in porcelain production, so as to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0021] Please refer to Figures 1 to 3 , the present utility model provides a technical solution:

[0022] Example 1: A ball mill for porcelain production that facilitates feeding, comprising a ball milling drum 4. The two ends of the ball milling drum 4 are rotatably installed on a first side frame 1 and a second side frame 2. A motor 3 for driving the ball milling drum 4 to rotate is provided on the second side frame 2. The other end of the ball milling drum 4 is rotatably sleeved with a bearing 8 between it and the first side frame 1.

[0023] The motor 3 drives the ball milling drum 4 to rotate, enabling the grinding balls inside it to fully contact the raw materials to achieve the purpose of grinding.

[0024] A plug rod 7 is inserted through the first side frame 1. The end of the plug rod 7 extends into the inner cavity of the ball milling drum 4. A protective cover 6 is provided at the end of the plug rod 7. One side of the protective cover 6 is inserted into the inner wall of the ball milling drum 4. A rotating groove 17 is provided on the inner wall of the ball milling drum 4, and a protective insertion ring 14 inserted into the rotating groove 17 is provided on the protective cover 6.

[0025] Through relative insertion, the protective cover 6 protects the insertion position of the plug rod 7 to prevent leakage.

[0026] The outer end of the plug rod 7 is rotatably installed on the first side frame 1 through a screw 10. A feed port 12 located outside the first side frame 1 is provided on the plug rod 7. A discharge port 13 extending into the inner cavity of the ball milling drum 4 is provided on the plug rod 7. An inclined inner flow channel 11 communicating the feed port 12 and the discharge port 13 is provided in the inner cavity of the plug rod 7.

[0027] Utilizing the connection of the feed port 12, the discharge port 13, and the inclined inner flow channel 11, the raw materials enter the inner cavity of the ball milling drum 4.

[0028] During the actual processing, first, the motor 3 drives the ball milling drum 4 to rotate, enabling the grinding balls inside it to fully contact the raw materials to achieve the purpose of grinding. When feeding is required, the screw 10 on the plug rod 7 rotates to achieve threaded rotation and propulsion, thereby laterally extruding the protective cover 6 to separate it from the inner wall of the ball milling drum 4 to form a gap.

[0031] A T-shaped pull rod 16 is provided on the side wall of the protective cover 6. The pull rod 16 is elastically inserted into the inner cavity of the limit ring 5.

[0032] By setting an elastic connection between the pull rod 16 and the limit ring 5, the purpose of limiting the rotation of the protective cover 6 is achieved, and the rotation and deviation of the protective cover 6 driven by the rotation and advancement of the plug rod 7 are avoided.

[0033] Embodiment 3: On the basis of Embodiment 2, a notch groove 15 is provided at the lower end of the protective insertion ring 14, the upper end of the notch groove 15 faces the discharge port 13, a right-angled extension frame 9 is provided on the outer side of the first side frame 1, a screw hole facing the plug rod 7 is provided on the extension frame 9, a screw 10 at the end of the plug rod 7 is threadedly rotatably installed in the screw hole, a rotating shaft 18 is provided at the end of the plug rod 7, and the plug rod 7 is rotatably installed on the protective cover 6 through the rotating shaft 18.

[0034] By setting the rotating shaft 18, the rotational connection between the plug rod 7 and the protective cover 6 is realized to achieve the purpose of rotational advancement. By setting the notch groove 15, the raw material falls along the notch groove 15 and enters the inner cavity of the ball milling drum 4, and the threaded rotational installation of the screw 10 is realized by using the extension frame 9.
