Deburring beads are introduced into the deburring drum 200, and then the rubber product is placed in the deburring drum 200. The drum cover 300 moves downward to cover the top of the drum housing 100 to block its port. Finally, the deburring drum 200 in the drum housing 100 is lifted and lowered. 00 rotates, driving the deburring balls and rubber products inside it to rotate together, and utilizing the contact between the two to achieve the effect of deburring the outer wall of the rubber product, wherein the bottom end of the deburring drum 200 is rotatably connected by a connecting seat 202, and a driving motor 203 is fixedly connected to the bottom end of the connecting seat 202. The driving end of the driving motor 203 penetrates the connecting seat 202 and is transmission-connected to the bottom end of the deburring drum 200, and the outer wall of the connecting seat 202 is fixedly connected to the inner side of the drum shell 100, and the connecting seat 202 is fixed in the drum shell 100. The dehairing drum 200 is fixed, which supports the dehairing drum 200 and facilitates the dehairing drum 200 to rotate. After the driving motor 203 is powered on, it drives the dehairing drum 200 to rotate and provides a rotational driving force. At the same time, the side wall of the drum cover 300 is fixedly connected to a connecting frame 301, and the end of the bottom end of the connecting frame 301 is fixedly connected to a lifting device 302 for driving the connecting frame 301 to rise and fall. The lifting device 302 can be an electric lifting rod, a hydraulic lifting rod or a pneumatic lifting rod, and its main function is to drive the connecting frame 301 to rise and fall. The frame 301 is lifted and lowered, thereby driving the drum cover 300 to move up and down, and the port of the drum housing 100 is blocked or opened. The bottom of the side wall of the lifting device 302 is fixedly connected with a guide rod 303, and the outer wall of the guide rod 303 is slidably plugged with the connecting frame 301. The setting of the guide rod 303 can guide the connecting frame 301 during the lifting process, thereby keeping the connecting frame 301 and the drum cover 300 vertically lifted, so as to enhance the accuracy of the positioning of the drum cover 300 and the stability of the lifting process;

[0021] The bottom end of the drum cover 300 is provided with a limiting mechanism for limiting the rotation trajectory of the top of the dehairing drum 200. The limiting mechanism extends into the drum housing 100 and is movably mounted on the outer wall of the dehairing drum 200, so as to limit the outer wall of the dehairing drum 200, so that the dehairing drum 200 will not shake during rotation and maintain coaxial rotation. In this way, the shaking and vibration generated during the rotation of the drum housing 100 are reduced, thereby reducing damage to the device due to shaking and enhancing the protection effect. The limiting mechanism includes an annular ball seat 400 fixedly connected to the bottom end of the drum cover 300. The annular ball seat 400 is located directly above the dehairing drum 200 and has an inner diameter larger than the outer diameter of the dehairing drum 200. The annular ball seat 400 is used to mount the outer wall of the dehairing drum 200, so that the dehairing drum 200 is limited and guided in the annular ball seat 400, and cannot shake due to position displacement.

[0022] In a preferred embodiment, the annular ball seat 400 includes an annular seat 402 fixedly connected to the bottom end of the drum cover 300, and a plurality of auxiliary balls 401 are arranged at intervals in an annular array on the inner side of the annular seat 402.

In the process of the dehairing drum 200 rotating, the auxiliary ball 401 will be driven to roll in its own position, so that the friction resistance between the dehairing drum 200 and the dehairing drum 200 can be reduced, thereby reducing energy loss, and also reducing the wear on the outer wall of the dehairing drum 200, with a higher protective effect. In addition, an annular track 201 is provided on the top of the outer wall of the dehairing drum 200, and the annular track 201 is composed of two O-rings arranged vertically at intervals. The two O-rings are respectively fixedly sleeved on the outer wall of the connecting seat 202, and the two O-rings are arranged at intervals up and down to form an annular channel therebetween. When the drum cover 300 moves downward, it drives the annular seat 402 to move, so that the auxiliary ball 401 squeezes the O-ring at the upper position, and then enters the annular channel between the two O-rings, which can guide the auxiliary ball 401, thereby helping to further enhance the limiting and guiding effect on the rotation of the dehairing drum 200.
