[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses an eMMC chip production waste processing device, including a grinding tube 1 and a grinding roller 13. The grinding roller 13 is vertically arranged inside the grinding tube 1. One end of the grinding roller 13 is threadedly connected to a first grinding cylinder 2, and the other end is threadedly connected to a second grinding cylinder 14. Multiple cutting blocks 3 are installed in a ring structure on the outer wall of the first grinding cylinder 2. Shafts 4 are installed at both ends of the grinding roller 13. Multiple positioning channels 17 are provided at one end of the grinding tube 1. Support frames 8 are provided on both sides of the grinding tube 1. One end of each support frame 8 extends through the positioning channel 17 into the grinding tube 1 and protrudes to form a positioning seat. The positioning seats are combined to form a positioning cylinder 15. The shaft 4 at one end is inserted into the positioning cylinder 15. The other end of each support frame 8 protrudes to form an arc-shaped part 11. The arc-shaped parts 11 are combined to form a central ring. The shaft 4 at the other end is set through the central ring. Multiple balls are movably installed on the bottom surface and inner wall surface of the positioning cylinder cavity, which reduces the friction between the ball and the shaft, allowing the shaft to rotate smoothly.

[0023] In this embodiment, a first grinding channel is formed between the first grinding cylinder 2 and the grinding tube 1, and a second grinding channel is formed between the second grinding cylinder 14 and the grinding tube 1. The opening at the upper end of the first grinding channel is the largest, and it is gradually reduced downward until it matches the width of the second grinding channel. Grinding patterns are provided on the outer ring of the second grinding cylinder 14 and the inner wall of the grinding tube 1, which are directly opposite the second grinding cylinder 14.

[0024] In this embodiment, a first gear 5 is installed on the shaft 4 near one end of the central ring. A second gear 7 is provided on one side of the first gear 5 and meshes with it. A motor 6 that drives the second gear 7 to rotate is installed on the second gear 7. A fixed frame that is connected to a support frame 8 on one side is installed on the outside of the motor 6.

[0025] In this embodiment, the positioning channel 17 is provided with sliding grooves 16 on both sides, and the support frame 8 is provided with sliding strips 9 on both sides opposite to the sliding grooves 16. The sliding strips 9 are slidably disposed in the sliding grooves 16.

[0026] In this embodiment, the first grinding cylinder 2 is arranged in a conical shape, and the end of the second grinding channel away from the first grinding cylinder 2 is connected to the outside.

[0027] In this embodiment, a base 12 is installed at one end of the grinding tube 1.

[0028] In this embodiment, cylinders 10 are installed on both sides of the grinding tube 1 facing the support frame 8. The piston rod of the cylinder 10 is fixedly connected to the support frame 8. The cylinder is connected to a power source, an air source and a controller.

[0029] Working principle:

[0030] Waste material is fed from the top of the grinding tube 1 and falls into the first grinding channel between the first grinding cylinder 2 and the inner wall of the grinding tube 1. Because the first grinding channel has a conical structure that is wider at the top and narrower at the bottom, the waste material moves downwards under gravity and is gradually compressed. At this time, the motor 6 drives the first gear 5 to rotate via the second gear 7, which in turn drives the shaft 4 and the grinding roller 13 to rotate as a whole. The first grinding cylinder 2, fixed to the upper end of the grinding roller 13, rotates accordingly, and the cutting blocks 3 on its outer wall cut and initially crush the waste material.

[0031] The initially crushed waste material continues to flow downwards into the second grinding channel (i.e., the gap between the second grinding cylinder 14 and the inner wall of the grinding tube 1). The second grinding cylinder 14 is fixed to the lower end of the grinding roller 13 by a threaded connection, and its outer wall has grinding patterns corresponding to the inner wall of the grinding tube 1. In the second grinding channel, the waste material is subjected to compression and shearing action between the rotating second grinding cylinder 14 and the stationary inner wall of the grinding tube 1, and is further ground into fine powder. Finally, the pulverized waste material is discharged from the outlet at the bottom of the second grinding channel, completing the processing.

[0032] Disassembly process: When the first grinding cylinder 2 or the second grinding cylinder 14 needs to be replaced due to wear, activate the cylinders 10 on both sides of the grinding tube 1 to push the support frame 8 outward along the positioning channel 17 (through the sliding engagement of the slide bar 9 and the slide groove 16). After the support frame 8 is disengaged, the positioning cylinder 15 and the centering ring no longer constrain the shaft 4, and the entire grinding roller 13 can be removed from the grinding tube 1.

[0033] Replacement of parts: After the grinding roller 13 is independent, the first grinding cylinder 2 and the second grinding cylinder 14 can be removed from the grinding roller 13 by twisting, without replacing the entire grinding roller, which reduces maintenance costs and improves disassembly and assembly efficiency.

[0034] Support structure: The support frame 8 positions the shafts 4 at both ends through the positioning cylinder 15 and the central ring, respectively, to ensure the stability of the grinding roller 13 when it rotates at high speed.

[0035] Power system: The motor 6 is fixed on the fixed frame on the side of the support frame 8. The power is transmitted to the shaft 4 through the gear set (the first gear 5 and the second gear 7 mesh) to drive the grinding roller 13 to rotate smoothly.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
