[0027] In order to make the purpose, scheme and beneficial effects of this application clearer, this application is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0028] Figure 1 and Figure 2 The front cross-sectional view and the three-dimensional exploded view of an embodiment of a grinding device of the present application are shown respectively. Figure 1 and Figure 2 The grinding device includes a barrel 100, which includes a feed port 110 and a discharge port 120. The raw material enters the barrel 100 through the feed port 110 and is discharged through the discharge port 120 after grinding. A screw 200 is provided inside the barrel 100. The screw 200 is arranged along the axial direction of the barrel 100 and is used to transport the raw material in the barrel 100 to the vicinity of the discharge port 120. The grinding assembly 300 is provided at the discharge port 120 and includes a grinding male head 310 and a grinding female head 320. The raw material is ground through the rotation and extrusion of the grinding male head 310 and the grinding female head 320 and is discharged from the grinding gap between the two. The coarseness of the grinding can be controlled by the size of the grinding gap.

[0029] However, after long-term use, the grinding male head 310 and the grinding female head 320 often become clogged or sticky, resulting in an inability to separate the grinding gap between the two, or the size of the grinding gap cannot be adjusted.

[0030] To this end, an elastic member 400 is further provided between the grinding male head 310 and the screw 200. The elastic member 400 is configured to push the grinding male head 310 away from the grinding female head 320. It is understood that the elastic member 400 should be in a compressed state, and the elastic restoring force generated is used to push the grinding male head 310, thereby preventing the grinding male head 310 from adhering to the grinding female head 320 and being unable to move.

[0031] Specifically, if Figure 1 As shown, the end of the screw 200 near the discharge port 120 is provided with a first insertion port 210 for inserting the grinding male head 310; the elastic member 400 is compressed by the grinding male head 310 in the first insertion port 210. This provides a space for accommodating the elastic member 400, which is conducive to maintaining the stability of the structure.

[0032] According to an exemplary embodiment of the present application, the grinding device further includes an adjustment component 500 provided at the discharge port 120, the adjustment component 500 is pressed against the grinding male head 310, and can adjust the size of the grinding gap by adjusting its own position. Figure 1 and Figure 3 As shown, the grinding male head 310 has a first position in which the adjustment assembly 500 is pressed against the grinding female head 320, and as shown in FIG. Figure 4 and Figure 5 A second position is shown where a grinding gap is created between the grinding nut 320 and the grinding nut 320 .

[0033] Furthermore, the elastic member 400 is always in a compressed state when the grinding male head 310 is in the first position and the second position. In this way, the grinding male head 310 is always pressed against the adjustment assembly 500 and moves with the adjustment assembly 500, thereby improving the adjustment sensitivity of the grinding gap size.

[0034] According to an exemplary embodiment of the present application, the adjustment assembly 500 includes a stud 510 and a nut 520 that can realize a screw drive; the nut 520 is rotatably connected to the discharge port 120 and drives the stud 510 to move axially along the barrel 100. Specifically, in this embodiment, the adjustment base 530 is fixedly mounted on the discharge port 120, and the nut 520 is rotatably connected to the adjustment base 530. By rotating the nut 520, the user can convert the rotational motion of the nut 520 into linear motion along the axial direction of the stud 510, thereby more accurately adjusting the size of the grinding gap.

[0035] Furthermore, when the grinding male head 310 is in the first position and the second position, it is squeezed by the stud 510 so that the elastic member 100 is always in a compressed state. In this way, the grinding male head 310 always moves with the adjustment assembly 500 under the push of the elastic restoring force, thereby improving the adjustment sensitivity of the grinding gap size.

[0036] According to an exemplary embodiment of the present application, Figure 1 As shown, the end of the stud 510 near the grinding male head 310 is provided with a second insertion port 511. The grinding male head 310 comprises a male head body 311 and a connecting rod 312 that extends axially through the male head body 311 and is fixedly connected to the male head body 311. The ends of the connecting rod 312 are respectively inserted into the first insertion port 210 and the second insertion port 511. Thus, the screw 200, the grinding male head 310, and the stud 500 are connected sequentially in the axial direction via the connecting rod 312, which helps improve the connection stability in this direction.

[0037] Furthermore, since the connecting rod 312 is fixedly connected to the male body 311, the elastic member 400 pushes the connecting rod 312 to move the male body 311 in a direction away from the grinding female head 320; the stud 510 presses the male body 311 to cause the connecting rod 312 to compress the elastic member 400.

[0038] According to an exemplary embodiment of the present application, Figure 1 and Figure 2 As shown, the grinding device further includes an inner sleeve 600 provided on the inner wall of the barrel 100 for preventing the grinding assembly 300 from shaking. Figure 1 For example, the inner sleeve 600 presses the connecting rod 312 and the grinding head 320 in the radial direction of the discharge port 120 to achieve anti-shake; in addition, the grinding device also includes a fixing ring 700 arranged on the outer wall of the discharge port 120 for pressing the inner sleeve 600 and the adjustment assembly 500, wherein the pressing direction of the fixing ring 700 is along the axial direction of the barrel 100 toward the inside.

[0039] According to an exemplary embodiment of the present application, Figure 6 As shown, the grinding device further includes a main body 800 and a driving assembly (not shown) disposed in the main body 800; the screw 200 and the grinding male head 310 are driven to rotate by the driving assembly.

[0040] Preferably, the screw 200 rotates by rolling balls, which are arranged between the base of the screw 200 and the rear seat of the barrel 100. To avoid wear of the adjacent parts by the balls, high-strength metal parts can be selected and arranged between the balls and the adjacent parts.

[0041] The components of different embodiments can be combined with each other in any feasible manner to achieve the purpose of this application.

[0042] It should be noted that this application should not be construed as limited to the embodiments described above, but rather should be construed as covering all possible implementations determined by the claims of this application in conjunction with the disclosure of the specification. Therefore, any simple modifications, equivalent variations, and modifications to the above embodiments that do not depart from the content of this application and are based on the technical essence of this application are within the scope of protection of this application.
