DETAILED DESCRIPTION

[0021] The following is combined with Figures 1 to 5 The utility model is described in detail.

[0022] The utility model discloses a three-roller grinding machine with a double-layer grinding structure, comprising a base 1, which can be fixed to the ground. A fixing frame 2 is provided on the base 1, a first grinding machine 3 is provided in the fixing frame 2, a feeder 4 is provided above the first grinding machine 3, and the first grinding machine 3 is provided with a grinding roller a31, a grinding roller b32, and a grinding roller c33 in sequence to form a three-roller grinding structure, wherein the grinding roller a31 is a slow roller, the grinding roller b32 is a medium-speed roller, and the grinding roller c33 is a fast roller. A fixed platen 34 is provided below the first grinder 3 and is fixedly connected to the fixed frame 2. This platen 34 prevents material from dripping from the first grinder 3 onto the bottom of the fixed frame 2. A first scraper 35 is provided at the edge of the fixed platen 34, which cooperates with the grinding roller c33. The first scraper 35 is equipped with a first guide plate 36 extending diagonally downward. The first scraper 35 scrapes material adhering to the grinding roller c33 and transports the material diagonally downward via the first guide plate 36. A second grinding mechanism 5 is also provided within the fixed frame 2, located below the first grinder 3. This second grinding mechanism 5 is sequentially equipped with grinding rollers d51, e52, and f53, forming a three-roller grinding structure. Grinding roller d51 is a slow-speed roller, grinding roller e52 is a medium-speed roller, and grinding roller f53 is a fast-speed roller. A follower platen 54 is located below the second grinding mechanism 5. This platen 54 prevents material from dripping from the second grinding mechanism 5 onto the bottom of the fixed frame 2. A second scraper 55 is located at one end of the follower platen 54 to scrape material off the grinding roller f53. The fixed frame 2 is provided with a chute 21, within which a slider 56 is located. The first grinding mechanism 3, the follower platen 54, and the slider 56 are connected. A drive motor 6 is provided on the fixed frame 2 to drive the slider 56. This structure allows the second grinding mechanism 5 to be moved and adjusted. When the second grinding mechanism 5 is moved to a designated position, the gap between the grinding rollers d51 and e52 is directly below the bottom end of the first guide plate 36. At this point, the first grinding mechanism 3 and the second grinding mechanism 5 form a double-layer grinding structure. After grinding in the first grinding mechanism 3, the material falls into the second grinding mechanism 5 for a second three-roller grinding operation, resulting in multiple grinding operations and high-quality grinding. Similarly, the second grinding mechanism 5 can be adjusted so that it no longer receives material directed off the first guide plate 36, transforming the double-layer grinding structure into a single-layer grinding structure, enabling diverse grinding methods. The system also includes a material transport plate 11. The base 1 is provided with guide rails 12, and the bottom of the material transport plate 11 is provided with guide grooves 13, allowing the material transport plate 11 to move on the base. The material transport plate 11 is used to place containers such as barrels. The material transport plate 11 moves the container to a designated position, allowing the user to select whether to receive material ground by the first grinding mechanism 3 or the second grinding mechanism 5, providing convenient operation.

[0023] The fixed frame 2 includes a first frame plate 22 and a second frame plate 23, and the first grinding machine 3 and the second grinding mechanism 5 are arranged between the first frame plate 22 and the second frame plate 23. The first frame plate 22 and the second frame plate 23 are closed, and the first frame plate 22 and the second frame plate 23 are equipped with a control device for controlling the drive motor 6, the first grinding machine 3, the second grinding mechanism 5, and the feeder 4.

[0024] The first frame 22 and the second frame 23 are both provided with a slide groove 21 at the same level. A cavity 24 is provided in the first frame 22. A driving device is provided in the cavity 24 for driving the slide 56. The two slides 56 form a bracket structure to maintain the balance of the second grinding mechanism 5 and the follower plate 54, and to provide high stability.

[0025] The drive device is sequentially provided with a transmission wheel 25 connected to the drive motor 6, a synchronous wheel 26 movably connected to the first frame 22, a transmission belt 27 is provided between the synchronous wheel 26 and the transmission wheel 25, and a slider 56 is provided with a connecting block 57 fixedly connected to the transmission belt 27. The drive motor 6 drives the drive device, causing the slider 56 to move linearly within the slide 21, thereby adjusting the position of the second grinding mechanism 5.

[0026] The two ends of the chute 21 are provided with first limit plates 28 for limiting the movable position of the slider 56. The first limit plates 28 can prevent the slider 56 from sliding out of the chute 21, and the safety is high.

[0027] Second limit plates 14 are provided at both ends of the base plate to limit the movable position of the transport plate 11. The transport plate 11 needs to have a high load-bearing capacity. In this solution, the transport plate 11 is usually made of steel and is relatively heavy. If the transport plate 11 detaches from the guide rail 12, it will be very difficult for the staff to return the transport plate 11 to the guide rail 12. Therefore, second limiters are provided at both ends of the base plate to prevent the transport plate 11 from detaching from the base plate.

[0028] A feed pipe 41 is provided above the feeder 4, and a discharge port 42 is provided below the feeder 4. Discharge port 42 is located above the gap between grinding rollers a31 and b32. Liquid silicone and other materials enter the feeder 4 through the feed pipe 41 and then fall into the first grinding mill 3 through the discharge port 42. This eliminates the need for manual mechanical operation to pour materials, saving manpower.

[0029] The feeder 4 is provided with a controller 43 outside, and the controller 43 is provided with a sensor 44 extending into the feeder 4. The sensor 44 can monitor the flow data of the material in the feeder 4, and transmit the signal through the controller 43, so that the feeder 4 can feed quantitatively, which is easy to use.

[0030] The second scraper 55 is provided with a second guide plate 58 extending obliquely downward. The material transport plate 11 is operated to move the container below the second guide plate 58. The material ground by the second grinding mechanism 5 falls into the container through the second guide plate 58, eliminating the need to manually scrape the material attached to the grinding roller f53, thereby improving grinding efficiency.

[0031] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
