[0014] Figure 2 yes Figure 1 Enlarged view of the structure at point A in the diagram. Detailed Implementation

[0015] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0016] like Figure 1-2As shown, a pulverizing device for producing composite prebiotic fiber powder includes a housing 1, with a chamber 11 inside the housing 1. A grinding seat 2 is provided on the inner wall of the chamber 11 and fixed to the inner wall of the chamber. A grinding hole 21 is provided in the middle of the grinding seat 2, and a rotatable main shaft 22 is provided at the axis of the grinding hole 21. A grinding blade 220 is provided on the side wall of the main shaft 22, located inside the grinding hole 21. The grinding blade is spirally arranged on the side wall of the main shaft and located inside the grinding hole, which can initially crush the composite prebiotic fiber. A grinding tool 3 is provided at the lower end of the main shaft 22, which can rotate synchronously with the main shaft 22. A first grinding surface 23 and a second grinding surface 31 are respectively provided between the bottom surface of the grinding seat 2 and the side surface of the grinding tool 3. Subsequently, the composite prebiotic fiber falls between the first grinding surface and the second grinding surface, and the grinding tool rotates in conjunction with the grinding seat. The composite prebiotic fibers are subjected to secondary pulverization to achieve the pulverization production of composite prebiotic fibers. The grinding mold can move up and down relative to the grinding seat, which changes the distance between the first grinding surface and the second grinding surface. The lower end of the main shaft 22 is equipped with a drive motor 242. The output shaft of the drive motor 242 is equipped with a screw 25 that is threadedly connected to the grinding mold 3. The drive motor at the lower end of the main shaft can drive the screw to rotate. When the screw rotates, the up and down movement of the grinding mold is controlled through the threaded connection with the grinding mold, thereby adjusting the distance between the first grinding surface and the second grinding surface. The distance adjustment is achieved by the rotation of the drive motor and the screw, which strengthens the control of grinding accuracy, makes the distance adjustment faster and more convenient, reduces the difficulty of adjustment, and at the same time, the adjustment accuracy of the grinding distance is higher and the adjustment is more reliable.

[0017] A grinding motor 12 is installed on the top of the housing 1. The output shaft of the grinding motor 12 is set downward and connected to the main shaft 22. The lower end of the main shaft 22 is connected to the upper end face of the fixed seat 24. The grinding motor is fixed on the top of the housing. The output shaft of the grinding motor extends downward into the cavity and is welded or screwed to the main shaft. A spiral grinding cutter is set on the section of the main shaft that passes through the grinding hole. The grinding motor drives the main shaft, so that the main shaft controls the grinding cutter and the grinding tool to rotate synchronously, and performs multi-step grinding of the composite prebiotic fiber simultaneously, thereby improving grinding efficiency and grinding quality.

[0018] like Figure 1-2As shown, a fixed seat 24 is provided at the lower end of the main spindle 22. A fixed groove 241 is provided at the bottom of the fixed seat 24. A drive motor 242 is embedded in the fixed groove 241. The output shaft of the drive motor 242 is set downward and connected to a screw 25. The screw 25 is threadedly connected to the grinding mold 3. The fixed seat is fixed to the lower end of the main spindle. The drive motor is fixed in the fixed groove with its output shaft facing downward. The screw is located at the center of the grinding mold. The drive motor drives the screw to rotate. The screw can control the up and down movement of the grinding mold through the thread to adjust the grinding spacing. An annular inner protrusion 243 is provided at the opening of the fixed groove 241, which abuts against the edge of the drive motor 242. The annular inner protrusion adds a limiting structure to the opening of the fixed groove to limit the installation of the drive motor and keep the drive motor stable. A limiting protrusion 244 is provided on the outer side of the fixed seat 24. A receiving groove 32 is provided on the top of the grinding mold 3 to accommodate the fixed seat 24. An axially arranged and connected groove 242 is provided on the inner wall of the receiving groove 32. The limiting protrusion 244 is fitted with a strip groove 321. A retaining spring 322 is provided at the top opening of the receiving groove 32, which abuts against the upper end face of the fixed seat 24. An annular groove 245 is provided on the outer wall of the limiting protrusion 244. An O-ring 246 is provided in the annular groove 245, which abuts against the side wall of the strip groove 321. The limiting protrusion is located in the strip groove and can slide along the strip groove. Thus, when the screw rotates, it restricts the rotation of the grinding wheel and realizes the up and down movement of the grinding wheel to complete the adjustment action. At the same time, when the grinding motor is driven, the grinding wheel can be driven to rotate horizontally through the spindle and the fixed seat to realize the grinding action. The annular groove on the outer wall of the limiting protrusion and the O-ring in the annular groove play a damping role, which can reduce the smoothness of the sliding of the limiting protrusion in the strip groove, improve the stability of the up and down movement adjustment of the grinding wheel, and reduce wear. At the same time, the retaining spring 322 provides secondary limiting for the fixed seat 24, ensuring its stability in the receiving groove 32 and facilitating assembly.

[0019] like Figure 1 As shown, the lower end of the screw 25 is provided with an extension section 251. The periphery of the extension section 251 is provided with a positioning groove 33 corresponding to the bottom of the mold 3. An oil-impregnated bearing 331 is provided on the inner wall of the positioning groove 33 and sleeved on the extension section 251. An oil seal 332 is provided at the bottom opening of the positioning groove 33. The lower end of the screw is located in the positioning groove through the extension section. The oil-impregnated bearing is sleeved on the extension section and fixed on the inner wall of the positioning groove, which provides support and fixation for the screw and ensures that the screw can rotate smoothly. The oil-impregnated bearing and the oil seal are existing technologies and will not be described in detail here. The oil seal can form a sealing effect on the positioning groove, ensuring structural stability and facilitating assembly.

[0020] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
