[0022] Reference Figures 1-4 This embodiment provides a detachable tool grinding machine, including a support device, a drive device, and a grinding device; The driving device and the grinding device are disposed opposite to each other on the supporting device; The grinding device includes an adjustment component 30 and a grinding blade assembly. The adjustment component 30 is disposed on the grinding blade assembly. The grinding blade assembly is detachably connected to the end of the support device away from the driving device via the adjustment component 30, and the grinding blade assembly is detachably connected to the driving device.

[0023] In the above embodiments, the detachable grinder includes a support device, a drive device, and a grinding device. The support device serves as the structural foundation of the entire grinder, supporting and fixing the remaining functional components. The drive device, the core unit providing power, is located at one end of the support device and is responsible for outputting rotational motion. The grinding device is located at the other end of the support device, opposite to the drive device, and performs the material grinding function. The grinding device further includes an adjustment component 30 and a grinding blade assembly: the grinding blade assembly is the working component that performs the actual grinding operation; the adjustment component 30 is fixedly connected to the top of the grinding blade assembly, serving as a connection medium, allowing the grinding blade assembly to be detachably assembled with the support device. The adjustment component 30 engages with the corresponding internal threads on the support device through its outer circumferential threads, and after screwing in, it securely locks the entire grinding blade assembly to the end of the support device away from the drive device; simultaneously, the bottom or axial end of the grinding blade assembly forms a detachable power docking interface with the drive device. When the adjusting component 30 is fully tightened, the grinding blade assembly is axially pressed and synchronously coupled with the drive device, ensuring stable operation. When the adjusting component 30 is screwed out in the reverse direction, the grinding blade assembly is completely released from the constraint of the support device and disconnected from the drive device, allowing it to be completely removed for cleaning or maintenance. The threaded engagement between the adjusting component 30 and the support device enables the grinding blade assembly to be completely disassembled, simplifying disassembly and assembly and effectively solving the pain point of cumbersome disassembly and assembly of existing blade sets. The grinding blade assembly can be removed separately for thorough cleaning, avoiding hygiene problems and reduced grinding accuracy caused by residue; it can also be inspected or replaced individually without disassembling the entire machine, significantly reducing usage and maintenance costs and fully meeting the needs for convenience, hygiene, and precision.

[0024] Reference Figures 1-4 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 driving device and the grinding blade assembly are disposed opposite to each other at both ends of the fixed bracket 11, and the driving device is connected to the grinding blade assembly through the fixed bracket 11.

[0025] In the above embodiment, the support device includes a support base 10 and a fixed bracket 11. The support base 10 is the basic load-bearing structure of the entire device, adopting an L-shaped design, consisting of a vertical part and a horizontal part, providing a stable support platform. The fixed bracket 11 is the core component for connection and conduction, installed on the top of the support base 10, and its extension direction is parallel to the horizontal part of the support base 10, forming a stable installation reference surface. The two ends of the fixed bracket 11 are used to assemble functional modules: the upper end is connected to the drive device, and the lower end is connected to the adjustment component 30 through a threaded engagement, thereby detachably fixing the grinding blade assembly. Thus, the drive device and the grinding blade assembly are arranged vertically opposite each other, located at the two ends of the fixed bracket 11, and the material or power is connected through the internal channel of the fixed bracket 11. The material to be ground is transported from the drive device side to the grinding blade assembly for processing through the internal channel of the fixed bracket 11. In addition, a powder cup 12 is placed on the upper surface of the horizontal part of the support base 10. The powder cup 12 is directly opposite the discharge port of the grinding blade assembly and is used to receive the powder or granular material after grinding. This stabilizes the center of gravity of the machine and ensures a clear material path, making it easy for the powder cup 12 to be aligned and receive powder. At the same time, the fixed bracket 11 effectively integrates the drive and grinding units, improving assembly accuracy and operational reliability.

[0026] Reference Figures 1-4 In one embodiment, the grinding blade assembly includes a blade assembly fixing base 310 and a grinding blade body 311. The grinding blade body 311 is disposed in the blade assembly fixing base 310 and is detachably connected to the driving device. The adjusting component 30 is disposed on the side of the blade assembly fixing base 310 away from the grinding blade body 311 and is detachably connected to the fixing bracket 11.

[0027] In the above embodiment, the grinding blade assembly consists of two parts: a blade assembly mounting base 310 and a grinding blade body 311. The blade assembly mounting base 310 is a hollow shell structure used to house and support the internal working components; its overall shape is cylindrical or cup-shaped. The grinding blade body 311 is entirely housed within the inner space of the blade assembly mounting base 310 and is the functional component directly involved in material cutting and grinding. Its output end is designed as an interface that allows for quick docking with an external drive device, thereby establishing a power transmission relationship. Furthermore, an adjustment component 30 is installed on the side of the blade assembly mounting base 310 away from the grinding blade body 311 (i.e., the outer end face). This component is not embedded inside but is fixedly connected to the outer end of the blade assembly mounting base 310, forming a detachable mechanical connection with the fixed bracket 11 in the machine. Thus, the entire grinding blade assembly can be assembled and disassembled from the external structure through the adjustment component 30, while the grinding blade body 311 achieves power coupling with the drive device through its own structure. The grinding blade body 311 is located in the central area inside the blade assembly fixing seat 310, and the adjustment component 30 is located on the outer side of the blade assembly fixing seat 310. The two do not interfere with each other in space but work together: the blade assembly fixing seat 310 serves as an intermediate carrier, which not only wraps and protects the grinding blade body 311, but also provides an installation reference for the adjustment component 30, ensuring that the overall structure is compact, the force is reasonable, and it supports quick assembly and disassembly.

[0028] Reference Figures 1-4 In one embodiment, the tool assembly fixing seat 310 is provided with a limiting post 312 protruding towards the fixing bracket 11, and the fixing bracket 11 is provided with a limiting hole 13 on the side away from the driving device, and the limiting hole 13 is arranged correspondingly to the limiting post 312.

[0029] In the above embodiment, one or more limiting posts 312 protruding towards the fixing bracket 11 are provided in the top region of the tool assembly fixing seat 310. The limiting post 312 is an axially extending cylindrical or prismatic boss, and its main function is to provide a preliminary positioning reference in the circumferential and axial directions during assembly. Correspondingly, limiting holes 13 are provided on the side of the fixing bracket 11 away from the driving device (i.e., the end face facing the tool assembly fixing seat 310). The position, number and shape of the limiting holes 13 correspond to the limiting posts 312. When the grinding tool assembly is installed close to the fixing bracket 11, the limiting posts 312 at the top of the tool assembly fixing seat 310 are aligned with and inserted into the limiting holes 13 at the bottom of the fixing bracket 11. This arrangement not only prevents the grinding tool assembly from rotating or loosening axially during operation, but also provides accurate initial alignment for subsequent threaded locking by adjusting the component 30.

[0030] Reference Figures 1-4In one embodiment, the grinding blade body 311 includes a blade disc 3110 and a conical blade component 3111. The blade disc 3110 is connected to the blade assembly fixing base 310 via a blade disc fixing member 3112. The conical blade component 3111 is disposed within the blade disc 3110 and is detachably connected to the driving device. A certain gap is formed between the blade disc 3110 and the conical blade component 3111.

[0031] In the above embodiment, the grinding cutter body 311 is jointly composed of a cutter disc 3110 and a conical cutter component 3111. The cutter disc 3110 has an annular or disc-shaped structure with multiple cutting edges and is installed inside the cutter assembly mounting base 310, reliably connected via a cutter disc fixing member 3112. The cutter disc fixing member 3112 is typically a retaining ring, pressure cap, or screw-like fastening structure, used to axially confine the cutter disc 3110 within the inner cavity of the cutter assembly mounting base 310, preventing displacement during high-speed rotation. The conical cutter component 3111 is located inside the central region of the cutter disc 3110, has a conical structure, and its surface is also provided with grinding teeth or cutting edges, forming a surrounding grinding channel with the inner edge of the cutter disc 3110. One end of the conical cutter component 3111 is designed as an interface for docking with an external drive device to achieve power input, and this connection is detachable for easy individual maintenance or replacement. Crucially, a controllable annular "gap" is maintained between the cutter head 3110 and the conical cutter component 3111. The size of this gap directly determines the particle size of the ground material. The entire grinding blade assembly, from the inside out, consists of: the innermost conical cutter component 3111 rotating at the center, surrounded by the stationary or relatively moving cutter head 3110. The cutter head 3110 is constrained by the cutter head fixing component 3112, which is integrally embedded in the inner cavity of the blade assembly fixing seat 310. This nested structure from the inside out ensures precise fit between the components and provides a structural basis for gap adjustment and modular assembly / disassembly.

[0032] Reference Figures 1-4 In one embodiment, the conical cutter component 3111 includes a conical cutter body 3113, a rotating shaft 3114, and a nut 3115. The conical cutter body 3113 is spaced apart within the cutter disc 3110. The rotating shaft 3114 is disposed through the conical cutter body 3113 and connected to the driving device. The nut 3115 is detachably connected to the end of the rotating shaft 3114 away from the driving device.

[0033] In the above embodiment, the conical cutter component 3111 consists of three parts: a conical cutter body 3113, a rotating shaft 3114, and a nut 3115. The conical cutter body 3113 is a metal component with a conical profile, and its outer surface is provided with grinding teeth or cutting edges for cooperating with the cutter disc 3110 to complete the shearing and crushing of materials. The rotating shaft 3114 is a rotating transmission rod that passes through the center of the conical cutter body 3113. One end (top) is designed as a power interface that can be connected to an external drive device to receive rotational power; the other end (bottom) extends beyond the conical cutter body 3113 for connecting fasteners. The nut 3115 is a detachable fastening element, typically with a hexagonal round head structure, screwed onto the end of the rotating shaft 3114 furthest from the drive device (i.e., the bottom), for axially pressing the conical cutter body 3113 to prevent loosening or axial displacement during high-speed rotation. The conical cutter body 3113 is fitted and fixed in the middle area of ​​the rotating shaft 3114, and is entirely placed in the internal cavity of the cutter head 3110, maintaining a certain annular gap with the inner wall of the cutter head 3110. This gap serves as the material grinding channel. The rotating shaft 3114 extends axially through the entire conical cutter body 3113, with its top end facing the drive device and its bottom end exposed below the conical cutter body 3113 for easy installation of the nut 3115. When the nut 3115 is tightened, it applies an axial preload to the conical cutter body 3113, ensuring its stability and preventing wobbling during operation. When maintenance or replacement is required, simply unscrew the nut 3115 to remove the conical cutter body 3113 from the rotating shaft 3114. The entire structural design achieves modularity and detachability of the conical cutter component 3111, while ensuring the reliability of power transmission and the stability of the grinding gap.

[0034] Reference Figures 1-4 In one embodiment, the adjustment assembly 30 includes an adjustment body 301 and an adjustment ring fixing plate 302. The adjustment ring fixing plate 302 is disposed on the blade assembly fixing seat 310. The adjustment body 301 is disposed on the side of the adjustment ring fixing plate 302 away from the blade assembly fixing seat 310 and is detachably connected to the fixing bracket 11.

[0035] In the above embodiment, the adjustment assembly 30 consists of two parts: an adjustment body 301 and an adjustment ring fixing plate 302. The adjustment ring fixing plate 302 is an annular disc-shaped component, fixedly installed on the outer end face of the blade assembly fixing seat 310, serving as a transitional connector between the adjustment assembly 30 and the blade assembly fixing seat 310. Its inner side is firmly connected to the blade assembly fixing seat 310, while its outer side provides an installation reference surface for the adjustment body 301. The adjustment body 301 is a knob or sleeve-shaped structure with external threads, located on the side of the adjustment ring fixing plate 302 away from the blade assembly fixing seat 310, i.e., facing outwards. Its external threads are designed to mate with the internal threaded holes on the fixing bracket 11, forming a detachable threaded connection. During assembly, the adjustment body 301 is screwed into the threaded hole of the fixing bracket 11 by rotation, thereby tightening and fixing the entire blade assembly fixing seat 310 and its internal components in a predetermined position; reverse rotation disengages the connection, allowing the grinding blade assembly to detach completely. The adjusting ring fixing plate 302 not only transmits the axial force of the adjusting body 301, but also ensures the uniform distribution of force during the adjustment process, preventing the tool assembly fixing seat 310 from being subjected to force misalignment. The threaded connection enables quick assembly and disassembly, and the adjusting ring fixing plate 302 ensures smooth force transmission, effectively balancing connection reliability and ease of operation.

[0036] Reference Figures 1-4 In one embodiment, the grinding blade assembly further includes a fixing rod 313 and a rod spring 314. The blade assembly fixing seat 310 is provided with a receiving hole 315. The fixing rod 313 is located in the receiving hole 315 and contacts the blade disc fixing member 3112, and passes through the receiving hole 315. The rod spring 314 is sleeved on the fixing rod 313 and contacts the bottom of the receiving hole 315.

[0037] In the above embodiment, the grinding tool assembly includes a fixing rod 313 and a rod spring 314. The receiving hole 315 is an axial through hole formed inside the tool assembly fixing seat 310, used to accommodate an elastic adjustment mechanism. The fixing rod 313 is a columnar push rod placed within the receiving hole 315 and slidable axially. One end extends out of the receiving hole 315 and directly contacts the tool disc fixing member 3112 to transmit axial pressure; the other end is located at the bottom region of the receiving hole 315. The rod spring 314 is sleeved on the outer periphery of the fixing rod 313, with its lower end abutting against the bottom of the receiving hole 315, and its upper end pressed down by the fixing rod 313, forming a pre-compressed state. When an external axial force is applied (such as by pressing with the adjusting ring fixing plate 302), the fixing member push rod 313 moves downward, further compressing the push rod spring 314; when the external force is released, the push rod spring 314 rebounds, pushing the fixing member push rod 313 back to its original position, thereby causing the cutter head fixing member 3112 and the cutter head 3110 to generate axial displacement, realizing dynamic adjustment of the grinding gap. In addition, the circumferential arrangement of the fixing member push rod 313 and the limiting post 312 are on the same arc line, ensuring symmetrical force and smooth movement. Crucially, after the adjusting ring fixing plate 302 is installed, it covers the receiving hole 315, enclosing the push rod spring 314 and the fixing member push rod 313 inside the cutter set fixing seat 310, preventing them from detaching at will, thus ensuring structural integrity and preventing the loss of parts.

[0038] Reference Figures 1-4 In one embodiment, the driving device includes a machine housing 20, a drive motor 21, and a transmission component 22. The machine housing 20 is disposed on the fixed bracket 11, the drive motor 21 is disposed inside the machine housing 20, and the transmission component 22 is disposed at one end of the drive motor 21 near the grinding blade assembly. The drive motor 21 is connected to the grinding blade assembly through the transmission component 22.

[0039] In the above embodiment, the drive device consists of three parts: a machine housing 20, a drive motor 21, and a transmission component 22. The machine housing 20 is a rigid shell structure, integrally mounted on a fixed bracket 11. The drive motor 21 is completely housed and fixed inside the machine housing 20, serving as the power source, with its output shaft facing the grinding blade assembly. At the end of the drive motor 21 near the grinding blade assembly, a transmission component 22 is connected. This transmission component 22 is typically a coupling, gear, or spline sleeve, used to smoothly transmit the rotational motion of the drive motor 21 to external actuators. Specifically, the output shaft of the drive motor 21 is directly coupled to the transmission component 22, while the other end of the transmission component 22 is designed as an interface that can dock with the rotating shaft 3114 in the grinding blade assembly, thus establishing a complete power transmission chain. The machine housing 20 is centrally fixed to the mounting bracket 11, the drive motor 21 is located at the rear of its inner cavity, and the transmission component 22 protrudes from the front of the machine housing 20, directly facing the entrance of the grinding blade assembly's rotating shaft 3114, ensuring precise coaxial docking of the two after assembly. This modular integration of the entire drive unit achieves enclosed protection and efficient power transmission for the power system, while also facilitating quick assembly and disassembly with the grinding blade assembly.

[0040] Furthermore, the drive unit also includes a storage bin 23, which is a container for temporarily storing materials to be ground (such as coffee beans, spice granules, etc.). Its main structure is mounted on a fixed support 11, typically located at the top or upper side of the equipment. The machine housing 20 and the storage bin 23 are integrally formed or rigidly connected, forming a single structure with no assembly gaps. The fixed support 11 has a material guide channel inside, allowing material communication between the storage bin 23 and the grinding blade assembly below. The bottom opening of the storage bin 23 is aligned with the material guide hole inside the fixed support 11. After flowing out of the storage bin 23, the material directly enters the feed inlet of the grinding blade assembly through the internal channel of the fixed support 11. The storage bin 23 is integrally connected to the machine housing 20 and directly connected to the grinding blade assembly via the fixed support 11, achieving a short feeding path, good sealing, and a stable structure, effectively preventing material leakage and blockage.

[0041] During assembly, first align the grinding device with the installation position of the whole machine, so that the limiting post 312 on the top of the tool assembly fixing seat 310 is precisely aligned with the limiting hole 13 at the bottom of the fixing bracket 11; then slowly rotate the adjusting body 301 so that its external thread gradually screws into the internal thread of the fixing bracket 11. During the tightening process, the entire grinding device moves upward along the axis, and at the same time, the rotating shaft 3114 in the grinding tool assembly is inserted into the transmission component 22 of the drive device to complete the power connection; continue to tighten until the limiting post 312 is fully engaged in the limiting hole 13 to achieve circumferential positioning and axial locking. At this time, the grinding device is firmly fixed on the whole machine. After assembly, the coarseness of the grinding particles can be controlled by fine-tuning the position of the adjusting body 301: when the adjusting body 301 (or the adjusting ring fixing plate 302) is screwed in further, the lower end of the fixing bracket 11 presses the bearing, causing the cutter head 3110 fixing seat to move downward, pressing the fixing member top rod 313, compressing the top rod spring 314, and the cutter head 3110 moves closer to the conical cutter, reducing the gap between them and making the grinding particles finer; conversely, when the adjusting body 301 is screwed out, the top rod spring 314 rebounds, pushing the fixing member top rod 313 upward, causing the cutter head fixing member 3112 and the cutter head 3110 to return to their original position, increasing the gap between the cutter head 3110 and the conical cutter, and making the grinding particles coarser. This assembly method has both quick installation and fine adjustment functions.

[0042] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
