At the same time, in order to cool the static grinding disc 2 and the dynamic grinding disc 3, a cooling system 6 is also provided;

[0033] Here we will briefly describe the connection and installation method between the existing technical structures, in which the receiving base 5 is fixedly installed on the upper layer of the frame table 4 and the static grinding disc 2 is installed on the top of the receiving base 5, please refer to Figure 1 and Figure 6 The receiving base 5 is constructed in the shape of a cylinder with an open top and a closed bottom. A mounting circular hole 51 for rotatably mounting the movable grinding disc 3 is provided at the bottom of the receiving base 5. An edge ring 52 protrudes upward at the edge of the mounting circular hole 51 of the receiving base 5, and the receiving base 5 is fixed to the frame 4 by bolts, and the bolt-fixed installation has the characteristic of being detachable.

[0034] At the same time, the moving grinding disc 3 passes through the bottom of the receiving base 5 and is rotatably installed therewith. A grinding gap 7 is provided between the moving grinding disc 3 and the static grinding disc 2. Figure 3 The movable grinding disc 3 is rotatably mounted in the edge ring 52 through a bearing, and an outer convex ring 31 is fixed at the outer edge of the movable grinding disc 3. The inner ring of the bearing matches the outer diameter of the movable grinding disc 3, and the outer ring of the bearing matches the inner ring of the edge ring 52 tightly, thereby realizing the axial rotation installation of the movable grinding disc 3. At the same time, the outer convex ring 31 is arranged above the edge ring 52. The outer convex ring 31 is arranged to prevent the grinding objects from falling into the bearing, and combined with the arrangement of the edge ring 52, the ground wolfberry paste just falls into the area between the edge ring 52 and the receiving base 5; please refer to Figure 3 and Figure 5The grinding part of the static grinding disc 2 is truncated cone-shaped and is installed on the receiving base 5 in a height-adjustable manner. The grinding part of the dynamic grinding disc 3 is also truncated cone-shaped and can be fitted with the grinding part of the static grinding disc 2. The distance between the grinding parts of the two is a grinding gap 7. When the height of the static grinding disc 2 to the receiving base 5 is adjusted, the gap between the static grinding disc 2 and the dynamic grinding disc 3, that is, the size of the grinding gap 7 can be adjusted to achieve grinding of wolfberries with different particle sizes.

[0035] In order to facilitate the feeding, the hopper 1 is installed at the top of the static grinding disc 2, and the fixed installation method with the static grinding disc 2 is bolted installation. It is necessary to explain that, please refer to Figure 3 ,lie in Figure 3 The rightmost structure is a circulating feeding structure, which is a design existing in the prior art. Here is a brief description. When the wolfberry grinding liquid falls into the area between the edge ring 52 and the receiving base 5, it can be introduced into the circulating pipe at the bottom, and then the circulating pipe is connected to the micro pump installed at the bottom of the frame 4. The liquid outlet of the micro pump is fixed with a bent pipe, one of the bent pipes is a circulating liquid outlet pipe extending to the hopper 1 and a discharging liquid outlet pipe facing the outside. Valves are provided on both pipes. That is to say, when it is necessary to circulate and grind all the time, open the valves on the micro pump and the circulating liquid outlet pipe, close the valve on the discharging liquid outlet pipe, and extract the wolfberry grinding liquid from the inside and return it to the hopper 1 through the circulating liquid outlet pipe for grinding again. Based on the prior art here, only the above brief description is made;

[0036] In order to adjust the grinding gap 7, a boss 21 is constructed at the edge of the static grinding disc 2, and a plurality of shafts 53 that slide through the boss 21 are vertically fixed at the outer edge of the receiving base 5, wherein two diagonal shafts 53 are screws, and nuts 54 located at the upper and lower sides of the boss 21 are threadedly connected to the screws. Figure 3 When the rotating nut 54 is moved downward along the screw rod, the static grinding disc 2 can be driven downward to adjust the grinding gap 7 to become smaller. When the rotating nut 54 is moved upward along the screw rod, the static grinding disc 2 can be driven upward to adjust the grinding gap 7 to become larger, thereby achieving the function of adjusting the grinding gap 7.

[0037] The main design structure of the present application is: a cooling system 6, which includes a first cooling part 61 arranged on the static grinding disc 2 and a second cooling part 62 arranged on the dynamic grinding disc 3, and the first cooling part 61 and the second cooling part 62 both use circulating water for cooling, specifically: the static grinding disc 2 is located above the boss 21 and is also integrally constructed with a stepped part 22, the first cooling part 61 includes a cooling groove 611 opened on the stepped part 22, the stepped part 22 is located at the edge of the cooling groove 611 and is constructed with a sealing groove 612 and a sealing gasket 613 is arranged in the sealing groove 612, a cover plate 614 is arranged above the cooling groove 611 to press the sealing gasket 613 and is fastened to the stepped part 22 by bolts, and a water inlet nozzle 615 and a water outlet nozzle 616 are connected and installed at the side wall of the cooling groove 611, please refer to Figure 5 When cold water enters from the water inlet nozzle 615 and then goes around the cooling groove 611 and then passes through the water outlet nozzle 616, the static grinding disc 2 can be cooled. It should be noted that the cooling groove 611 between the water inlet nozzle 615 and the water outlet nozzle 616 is closed and not conductive. Figure 5 As can be seen in the figure, the cooling water designed in this way can flow along the cooling groove 611 once and then flow out through the water outlet nozzle 616.

[0038] See also Figure 3The main innovative design structure of the present application lies in the second cooling part 62.

At the same time, after cooling, the water flows back into the water cooling barrel 621 under gravity. It should be noted that in order to prevent the water from being thrown out, the lower end of the movable grinding disc 3 needs to be raised into the water cooling barrel 621. At the same time, in order to connect the first cooling part 61, the hard water spray pipe 623 is also connected to a hard water inlet conduit 625, and the water cooling barrel 621 is also provided with a hard water outlet conduit 626 arranged side by side with the hard water inlet conduit 625. The hard water inlet conduit 625 and the hard water outlet conduit 626 are fixed to the side of the rack 4 through a clamping pipe 627. The hard water inlet conduit 625 is connected to the water inlet nozzle 615 through a hose, and the hard water outlet conduit 626 is connected to the water outlet nozzle 616 through a hose. When the water pump 622 pumps water, in addition to supplying water to the hard water spray pipe 623, it also supplies water to the hard water inlet conduit 625. The cooling water flows from the hard water inlet conduit 625 to the hose, and then passes through the water inlet nozzle 615 and the cooling groove 611 for a circle, and then returns to the water cooling barrel 621 from the water outlet nozzle 616, the hose, and the hard water outlet conduit 626, thereby realizing the cooling of the movable grinding wheel 3 and the static grinding wheel 2.
