There are two grinders, and both ends of the front rocker arm and the rear rocker arm are rotatably connected to the sides of the two grinders respectively.

[0010] The drive assembly includes a drive cylinder, one end of which is hinged to the end of the front rocker arm, and the other end of which is rotatably connected to the frame.

[0011] Furthermore, the number of the grinding machines is four, and the four grinding machines are distributed in pairs on both sides of the inside of the frame, and are movably connected to the frame through two sets of floating connection components;

[0012] The number of driving cylinders is two. One end of each driving cylinder is hinged to the end of the two front rocker arms, and the other end of each driving cylinder is rotatably connected to the frame.

[0013] Furthermore, both ends of the front rocker arm and the rear rocker arm are provided with a reinforcing rod and a first connecting rod extending toward the grinder. One end of the first connecting rod is rotatably connected to the end of the front rocker arm or the rear rocker arm through a connecting shaft. The other end of the first connecting rod passes through the reinforcing rod and is fixedly connected to the grinder. The end of the reinforcing rod is provided with a supporting shaft, which is sleeved around the periphery of the first connecting rod.

[0014] Furthermore, the loading and unloading mechanism includes a loading and unloading platform, a loading cylinder and a unloading cylinder, the loading cylinder and the unloading cylinder are fixed on the loading and unloading platform, and one end of each extends toward the clamping mechanism.

[0015] The upper and lower material platforms are equipped with upper and lower material guide rails and lower material guide rails;

A discharging plate is slidably mounted on the discharging slide rail, and the driving end of the discharging cylinder is fixedly connected to the bottom surface of the discharging plate.

[0017] Furthermore, the frame is equipped with an electrical control cabinet, the opening of which is flush with the outer side of the frame and is rotatably connected to a cabinet door panel.

[0018] Furthermore, the outer side of the frame is surrounded by a sealing plate, the sealing plate has an inspection opening, and an inspection door is rotatably connected to the inspection opening.

[0042] Example

[0043] Please refer to Figure 1-5As shown, this embodiment provides a grinding system, including a frame 1, a loading / unloading mechanism 2, a clamping mechanism 3, and a grinding machine 4. The frame 1 is equipped with a floating connection assembly 5 and a drive assembly 6. The grinding machine 4 is movably connected to the frame 1 via the floating connection assembly 5. The drive end of the drive assembly 6 is driven by the grinding machine 4, and the drive assembly 6 drives the grinding machine 4 to move. The loading / unloading mechanism 2 and the clamping mechanism 3 are disposed within the frame 1, with the clamping mechanism 3 located between the loading / unloading mechanism 2 and the grinding machine 4.

[0044] The clamping mechanism 3 clamps the material from the loading / unloading mechanism 2 and then grinds it using the grinding machine 4. The grinding machine 4 is movably connected to the frame 1 via a floating connection component 5. The drive end of the drive mechanism is connected to the grinding machine 4, providing support and ensuring close contact between the grinding machine 4 and the material. When the force applied by the clamping mechanism 3 to the material exceeds the support force of the drive mechanism, the grinding machine 4 moves in the opposite direction via the floating connection component 5, reducing friction and thrust on the material and preventing damage to the material and the clamping mechanism 3. The clamping mechanism 3, in conjunction with the loading / unloading mechanism 2, performs loading, grinding, and unloading of materials, effectively improving grinding efficiency.

[0045] Please refer to Figure 3-5 As shown, specifically, the floating connection assembly 5 includes a front rocker arm 51 and a rear rocker arm 52, both of which are rotatably connected to the frame 1 at their midpoints. In this embodiment, there are two grinders 4, arranged vertically at intervals. Both ends of the front rocker arm 51 and the rear rocker arm 52 are rotatably connected to the sides of the two grinders 4. A parallelogram floating structure is formed between the front rocker arm 51, the rear rocker arm 52, and the two grinders 4, controlling the two grinders 4 to move synchronously in opposite directions. When the upper grinder 4 moves backward and descends, the lower grinder 4 moves forward and ascends, or the two move in opposite directions, achieving multi-faceted grinding while reducing the force applied to the material, further improving grinding efficiency. The front rocker arm 51 and the rear rocker arm 52 connect and support the two grinders 4 at their front and rear ends, effectively ensuring the stability of the two grinders 4 during operation and preventing excessive deflection of the grinders 4 under the push of the material, which would affect the grinding effect. In this embodiment, the drive assembly 6 includes a drive cylinder. One end of the drive cylinder is hinged to the end of the front rocker arm 51, and the other end is rotatably connected to the frame 1. The drive cylinder provides a limiting force to the front rocker arm 51, thereby controlling the two grinding machines 4 to maintain stable positions. At the same time, it provides a floating threshold. When the driving force applied to the material by the clamping mechanism 3 is greater than the floating threshold, the grinding machine 4 retracts, reducing the magnitude of the reaction force provided to the material, thereby protecting the material and the clamping mechanism 3.

[0046] Please refer to Figure 2As shown, furthermore, there are four grinding machines 4, distributed in pairs on both sides of the interior of the frame 1, and movably connected to the frame 1 through two sets of floating connection components 5. There are two drive cylinders, one end of which is hinged to the end of each of the two front rocker arms 51, and the other end of each of the two drive cylinders is rotatably connected to the frame 1. This fully utilizes the two sides of the interior of the frame 1, improving the utilization rate of the interior space of the frame 1. At the same time, the grinding grits of the grinding machines 4 are different, and different steps of grinding are completed in one grinding process, further improving grinding efficiency. Similarly, six grinding machines 4 can be set, arranged in threes on both sides of the interior of the frame 1, or in pairs on both sides of the interior of the frame 1 and in the middle of the frame 1 using a hoisting structure, or even more grinding machines 4 can be set.

[0047] In this embodiment, the grinding machine 4 is a belt grinding machine 4. Similarly, a wheel grinding machine 4 or other grinding structures can be provided.

[0048] Please refer to Figure 3 As shown, furthermore, both ends of the front rocker arm 51 and the rear rocker arm 52 are provided with reinforcing rods 512 and first connecting rods 511 extending toward the grinder 4. One end of the first connecting rod 511 is rotatably connected to the end of the front rocker arm 51 or the rear rocker arm 52 via a connecting shaft 513. The other end of the first connecting rod 511 passes through the reinforcing rod 512 and is fixedly connected to the grinder 4. The end of the reinforcing rod 512 is provided with a supporting shaft 514, which is sleeved around the periphery of the first connecting rod 511. The first connecting rod 511 connects to the grinder 4 and is provided with the reinforcing rod 512. The end of the reinforcing rod 512 supports the middle part of the first connecting rod 511, reducing the force on the first connecting rod 511, protecting the first connecting rod 511, and increasing the support force on the grinder 4, ensuring that the grinder 4 has better stability during the grinding process and improving the grinding accuracy.

A loading plate 26 is slidably arranged on the loading slide rail 24, and the driving end of the loading cylinder 22 is fixedly connected to the bottom surface of the loading plate 26. A unloading plate 27 is slidably arranged on the unloading slide rail 25, and the driving end of the unloading cylinder 23 is fixedly connected to the bottom surface of the unloading plate.
