[0022] Reference Figures 1-2 This embodiment provides a grinding machine with detachable blade assembly, including a support device, a drive device, and a grinding blade assembly device; The driving device and the grinding blade assembly are respectively mounted on the support device; The grinding tool assembly includes a cutting disc assembly 30 and a conical blade assembly. The cutting disc assembly 30 is detachably connected to the end of the support device away from the drive device. The conical blade assembly is adjustablely disposed within the cutting disc assembly 30 and is detachably connected to the drive device.

[0023] In the above embodiments, the detachable grinder consists of three core components: a support device, a drive device, and a grinding blade assembly. The support device, serving as the basic load-bearing structure, secures and supports the remaining components. The drive device, providing rotational power, is mounted at one end of the support device. The grinding blade assembly is located at the other end of the support device, positioned opposite the drive device, with the two aligned spatially and functionally through the support device. The grinding blade assembly further includes a blade disc assembly 30 and a conical blade assembly. The blade disc assembly 30 is detachably connected to the end of the support device furthest from the drive device. The conical blade assembly is adjustablely positioned inside the blade disc assembly 30 and detachably connected to the drive device, ensuring effective power transmission while supporting flexible assembly and gap adjustment. During operation, a predetermined gap is maintained between the blade disc assembly 30 and the conical blade assembly. This gap is crucial for shearing, compressing, and grinding materials (such as coffee beans) into powder. This grinding machine features a rational layout of the support, drive, and grinding blade assembly, along with a detachable connection between the blade assembly 30 and the support, and a detachable and adjustable design between the conical blade assembly and the drive, significantly simplifying the assembly and disassembly process. Its detachable nature allows for thorough cleaning of the blade assembly, completely removing residue and ensuring food hygiene. It also prevents residue buildup from altering the grinding gap, ensuring stable grinding precision. Furthermore, the blade assembly can be individually inspected and replaced without replacing the entire machine, significantly reducing operating and maintenance costs.

[0024] Reference Figures 1-2 In one embodiment, the support device includes a support base 10 and a fixed bracket 11. The fixed bracket 11 is disposed on the support base 10. The drive device and the cutter head assembly 30 are disposed opposite to each other at both ends of the fixed bracket 11, and the drive device is connected to the cutter head assembly 30 through the fixed bracket 11.

[0025] In the above embodiment, the support device is composed of a support base 10 and a fixed bracket 11. The support base 10 has an L-shaped structure, including a vertical section and a horizontal section. The vertical section provides overall height support and stability, while the horizontal section extends horizontally and serves as a base platform for supporting other components. The fixed bracket 11 is installed on top of the support base 10, and its overall extension direction is parallel to the horizontal section of the support base 10. The drive device and the cutter head assembly 30 are respectively located at both ends of the fixed bracket 11, arranged vertically relative to each other. The drive device is located at the upper end of the fixed bracket 11, while the cutter head assembly 30 is fixed to the lower end of the fixed bracket 11 by a threaded connection. The fixed bracket 11 not only serves as a mechanical connection bridge between the drive device and the cutter head assembly 30 but also connects their internal channels, thus forming a grinding path for the material from top to bottom. A powder cup 12 is placed on the upper surface of the horizontal section of the support base 10. The powder cup 12 is precisely aligned with the discharge port below the cutter head assembly 30 to directly receive the powder or granular material that falls after grinding, preventing spillage and improving efficiency.

[0026] Reference Figures 1-2 In one embodiment, the driving device includes a machine housing 20 and a drive motor 21. The drive motor 21 includes a drive body 210 and a motor shaft 211. The machine housing 20 is disposed on the fixed bracket 11. The drive body 210 is disposed inside the machine housing 20. The motor shaft 211 is disposed at one end of the drive body 210 near the conical cutter assembly. The motor shaft 211 passes through the fixed bracket 11 and is connected to the conical cutter assembly.

[0027] In the above embodiment, the drive device consists of a machine housing 20 and a drive motor 21. The machine housing 20 is a rigid shell structure used to house and protect the internal moving parts. It is mounted on a fixed bracket 11. The drive motor 21 is built into the machine housing 20 and specifically includes two core components: a drive body 210 and a motor shaft 211. The drive body 210 is the power source of the motor, responsible for converting electrical energy into mechanical rotational energy. It is completely housed within the closed cavity formed by the machine housing 20 to isolate external dust and foreign objects. The motor shaft 211 extends from the end of the drive body 210 near the conical cutter assembly. One end is firmly connected to the rotor output end of the drive body 210, and the other end extends outward axially. The motor shaft 211 passes through the fixed bracket 11, that is, after exiting from inside the machine housing 20, it continues to pass through the central through hole of the fixed bracket 11 and finally connects with the conical cutter assembly, thereby directly transmitting the rotational motion to the grinding part, effectively protecting the drive body 210, shortening the transmission path, and improving power transmission efficiency and operational stability.

[0028] Furthermore, the drive unit further includes multiple ball bearings 22, which are spaced apart inside the fixed bracket 11, specifically distributed at different positions within the cavity of the fixed bracket 11 along its axial direction to form a multi-point support structure. The inner ring of each ball bearing 22 is tightly fitted onto the motor shaft 211, while the outer ring is fixed to the inner wall of the fixed bracket 11, thereby stably supporting the motor shaft 211 within the fixed bracket 11. This structure significantly improves the stability and precision of the motor shaft 211's operation, reduces vibration and wear, and ensures consistent grinding.

[0029] Reference Figures 1-2 In one embodiment, the cutter head assembly 30 includes a cutter group fixing seat 301, which includes a fixing body 3010 and a threaded connection part 3011. The threaded connection part 3011 is disposed on the fixing body 3010, and the fixing body 3010 is threadedly connected to the fixing bracket 11 through the threaded connection part 3011.

[0030] In the above embodiment, the cutter head assembly 30 is composed of a cutter set fixing seat 301, which further includes two key parts: a fixing body 3010 and a threaded connection part 3011. The fixing body 3010 is the main structure of the cutter set fixing seat 301, typically cylindrical or annular. The threaded connection part 3011 is located at one end of the fixing body 3010, specifically a connection structure with standard threads machined on its inner circumference. Its function is to achieve a detachable connection between the cutter set fixing seat 301 and the external support structure. The threaded connection part 3011 is designed to form a matching threaded pair with the fixing bracket 11, allowing the fixing body 3010 to be screwed into or out of the fixing bracket 11 via the threaded connection part 3011, thereby completing installation or disassembly. This connection method determines that the cutter head assembly 30 and the fixed bracket 11 have an axial threaded fit: when the threaded connection 3011 is tightened onto the fixed bracket 11, the entire cutter head fixing seat 301 is firmly positioned at the end of the fixed bracket 11, ensuring that there will be no loosening or displacement during the grinding process; conversely, when cleaning or replacement is required, it can be easily separated by simply rotating in the opposite direction. This not only simplifies the assembly process but also gives the cutter head assembly 30 a high degree of independence and interchangeability. At the same time, the self-locking characteristic provided by the threaded connection also ensures the safety and reliability of the equipment during operation.

[0031] Reference Figures 1-2 In one embodiment, the cutter head assembly 30 further includes a cutter head body 302, which is fixedly connected within the fixed body 3010 and forms a certain gap with the conical cutter assembly. The cutter head body 302 is connected to the driving device through the fixed bracket 11.

[0032] In the above embodiments, the cutter head assembly 30 further includes a cutter head body 302. The cutter head body 302 is the core component for realizing the material grinding function. It has a hollow structure and an hourglass shape, consisting of two symmetrical or asymmetrical but interconnected conical cavities connected by a narrow channel. This structure facilitates the uniform passage of material through the grinding area under the action of gravity and rotational shear force. The cutter head body 302 is firmly fixed inside the fixed body 3010, usually through interference fit, snap-fit, welding, or screws to achieve integrated assembly. In terms of spatial layout, a specific annular gap is reserved between the lower part of the cutter head body 302 and the conical cutter assembly. This gap is the actual grinding working area, where the material is crushed into the required particle size by compression, shearing, and friction. Meanwhile, the cutter head body 302 is connected to the drive device via the fixed bracket 11—here, "connected" refers to the structural connection along the material or power transmission path: the material to be ground can enter the cutter head body 302 from top to bottom through the inner cavity of the fixed bracket 11, while the conical cutter assembly is rotated by the drive device, inserted into the cutter head body 302, and cooperates with it. In the entire structure, the hourglass-shaped hollow design of the cutter head body 302 not only optimizes the material flow path but also enhances grinding efficiency and uniformity.

[0033] Reference Figures 1-2 In one embodiment, the conical cutter assembly includes a conical cutter body 310, an elastic member 311, and an adjusting member 312 connected to the motor shaft 211. The conical cutter body 310 is located between the elastic member 311 and the adjusting member 312, and the conical cutter body 310 is spaced apart within the cutter disc body 302.

[0034] In the above embodiment, the conical blade assembly consists of three parts: a conical blade body 310, an elastic component 311, and an adjusting component 312. These three parts are sequentially assembled on the motor shaft 211 along the axial direction. The conical blade body 310 is a rigid component with a conical profile, which gradually narrows from top to bottom and is generally conical or truncated cone-shaped. It is used to cooperate with the blade disc body 302 to form a shearing and grinding surface. The conical blade body 310 is directly connected to the motor shaft 211 and rotates synchronously with the motor shaft 211. During operation, it is inserted into the blade disc body 302, and an annular gap is maintained between its lower part and the lower part of the blade disc body 302. This gap is the key area for material crushing. The elastic component 311 is located on one side (usually the top) of the conical cutter body 310 to provide axial elastic force, allowing the conical cutter body 310 to maintain its initial position without external force intervention. The adjusting component 312 is located on the other side (usually the bottom) of the conical cutter body 310, opposite to the elastic component 311. It applies pressure or releases stress to the elastic component 311 through axial displacement, thereby changing the position of the conical cutter body 310 relative to the cutter head body 302. Specifically, the conical cutter body 310 is sandwiched between the elastic component 311 and the adjusting component 312, and the three are coaxially mounted on the motor shaft 211, forming an axial arrangement of "elastic component 311—conical cutter body 310—adjusting component 312". When the adjusting component 312 is operated, the elastic component 311 can be compressed or relaxed, thereby pushing or releasing the conical cutter body 310, causing it to move slightly along the direction of the motor shaft 211, ultimately achieving continuous adjustment of the gap between the lower part of the conical cutter body 310 and the lower part of the cutter head body 302. The entire structure ensures that the conical cutter assembly can rotate stably and has flexible gap adjustment capabilities to meet different grinding fineness requirements.

[0035] Reference Figures 1-2 In one embodiment, the elastic component 311 includes a washer 3110 and a spring 3111. The washer 3110 is sleeved on the motor shaft 211 and contacts the ball bearing 22. The spring 3111 is sleeved on the motor shaft 211, and both ends of the spring 3111 are in contact with the washer 3110 and the conical cutter body 310, respectively.

[0036] In the above embodiment, the elastic component 311 is composed of a gasket 3110 and a spring 3111, which work together to provide axial elastic support force and are housed as a whole in the cavity formed within the fixed bracket 11. Among them, the shim 3110 is a ring-shaped thin sheet rigid element, the inner hole size of which matches the outer diameter of the motor shaft 211. It can be tightly fitted on the motor shaft 211 and is located on the side close to the ball bearing 22. The spring 3111 is a helical compression spring 3111, which is also fitted on the motor shaft 211 and located on the other side of the shim 3110. Its inner diameter is slightly larger than the outer diameter of the motor shaft 211 to ensure smooth sliding. The two ends of the spring 3111 are in contact with the shim 3110 and the conical cutter body 310, respectively. That is, one end abuts against the shim 3110 and the other end abuts against the conical cutter body 310. When the conical cutter body 310 is subjected to axial displacement due to adjustment or grinding force, the spring 3111 is compressed or stretched. Through elastic deformation, it absorbs or releases energy, so that the conical cutter body 310 can dynamically adjust its position and maintain a stable gap with the cutter disc body 302. This structure effectively buffers axial impact, maintains the stability of the grinding gap, and improves the smoothness of operation and adjustment sensitivity.

[0037] Reference Figures 1-2 In one embodiment, the adjusting component 312 includes a conical cutter disc 3120 and a button 3121. The conical cutter disc 3120 is sleeved on the motor shaft 211 and located at the end of the conical cutter body 310 away from the elastic component 311. The button 3121 is threaded onto the motor shaft 211 and located at the end of the conical cutter disc 3120 away from the conical cutter body 310.

[0038] In the above embodiment, the adjusting component 312 consists of a conical cutter disc 3120 and a button 3121. The conical cutter disc 3120 is an annular or disc-shaped component with a through hole in the center that matches the motor shaft 211. It can be freely fitted onto the motor shaft 211 and slide axially or rotate with the shaft. Its installation position is located at the end of the conical cutter body 310 away from the elastic component 311, that is, below the conical cutter body 310, directly contacting the end face of the conical cutter body 310 or being linked with it through structural limiting. The button 3121 is a tightening component with internal threads. Its internal threads match the external threads at the end of the motor shaft 211, and it can be threadedly connected to the motor shaft 211 by rotation. The button 3121 is located on the side of the conical cutter disc 3120 away from the conical cutter body 310, that is, at the outermost end of the entire adjusting component 312. Its end face or inner shoulder abuts against the corresponding end face of the conical cutter disc 3120. When the knob 3121 is tightened clockwise, it pushes inward along the motor shaft 211, pressing the conical cutter disc 3120 towards the conical cutter body 310. This pushes the conical cutter body 310 upward against the elastic force of the elastic component 311, reducing the gap between the conical cutter body 310 and the cutter disc body 302. Conversely, when the knob 3121 is loosened counterclockwise, the elastic component 311 releases energy, pushing the conical cutter body 310 back, increasing the gap. The entire adjusting component 312 is arranged axially along the motor shaft 211 in the pattern of "conical cutter body 310—conical cutter disc 3120—knob 3121," with all three coaxially mounted on the motor shaft 211, forming a mechanically linked adjusting system. This structure ensures that the user can steplessly and intuitively control the grinding coarseness simply by rotating the knob 3121, and the adjustment process is stable, reliable, and not easily loosened.

[0039] Reference Figures 1-2 In one embodiment, the drive device further includes a storage bin 23, which is disposed on the fixed bracket 11 and integrally connected to the machine housing 20. The storage bin 23 is connected to the cutter head assembly 30 through the fixed bracket 11.

[0040] In the above embodiment, the drive device further includes a storage bin 23, which, together with the machine housing 20, the fixed support 11, and the cutter head assembly 30, constitutes a complete material conveying and grinding pathway. The storage bin 23 is a container structure for temporarily storing materials to be ground (such as coffee beans, spices, etc.). Its interior forms a closed or semi-closed cavity capable of holding a certain amount of raw material, and it achieves orderly feeding under gravity or auxiliary mechanisms. The storage bin 23 and the machine housing 20 are manufactured as a single unit. The storage bin 23 is mounted on the fixed support 11, specifically in the upper region of the fixed support 11. The storage bin 23 is connected to the cutter head assembly 30 through the fixed support 11. The fixed support 11 has a channel running through its upper and lower ends. The upper end of this channel connects to the bottom outlet of the storage bin 23, and the lower end aligns with the feed inlet of the cutter head assembly 30, thus forming a continuous material path from the storage bin 23 → the inner cavity of the fixed support 11 → the cutter head assembly 30. This ensures that materials can enter the grinding area directly and smoothly without the need for external piping or additional guiding structures, achieving automatic material flow, reducing the risk of blockage, and improving the continuity of material supply and the overall integration of the machine.
