During rotation, when the discharge hole 3184 moves to the arc plate 3185 area, the upper feeding will stop, and the upper and lower discharge holes 3184 will overlap at the same time, and the meal replacement powder will enter the distribution pipe 319 from the discharge pipe 3191, and enter the two grinding components to perform graded grinding on the meal replacement powder.

[0049] like Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, in one embodiment, the grinding mechanism 300 also includes a cylinder 324 fixedly connected to the shell 200, the inner top wall of the cylinder 324 is fixedly connected to the second spring 325, the bottom end of the second spring 325 is fixedly connected to the piston rod 326, the top end of the piston rod 326 is fixedly connected to the contact plate 327, the other end of the contact plate 327 passes through the second spring 325 and the cylinder 324 in sequence and contacts the cam 323, two second collection frames 3282 are arranged at the material placing plate of the frame 100, a transverse tube 3284 is arranged between the second collection frames 3282, and an air pipe 328 is arranged between the transverse tube 3284 and the cylinder 324.

[0050] A mounting frame 3193 is provided at the top of the distribution tube 319, a three-way tube 3192 is provided between the two mounting frames 3193 and the cylinder 324, a rotating wheel 3194 is rotatably connected in the mounting frame 3193, a return spring is fixedly connected to the inner wall of the distribution tube 319, an extrusion cylinder 3195 is fixedly connected to the top of the return spring, an arc ring 3196 in contact with the rotating wheel 3194 is fixedly connected to the top of the extrusion cylinder 3195, and the bottom end of the extrusion cylinder 3195 passes through the return spring.

[0051] In this embodiment, the fourth motor 322 drives the rotation of the cam 323, driving the sieve plate 320 to move up and down reciprocatingly, and the first connecting rod 3202, the first spring 3203 and the second connecting rod 3204 are used to drive the sieve plate 320 to reciprocate for efficient screening. At the same time, the cam 323 will synchronously squeeze the contact plate 327 when rotating. Under the action of the second spring 325, the piston rod 326 reciprocates in the cylinder 324. Under the action of the two one-way valves 3281, the gas at the bottom of the second collection frame 3282 will be extracted and discharged into the housing 200. An air duct will be formed, and the gas in the upper part of the shell 200 will flow to the lower area to form a predetermined ventilation duct, which will be used to store the meal replacement powder that meets the specifications in the second collection frame 3282. The gas in the cylinder 324 will enter the installation frame 3193 through the three-way pipe 3192, and the gas will blow the rotating wheel 3194 to rotate. The rotation gap of the rotating wheel 3194 will be used to reciprocate the arc ring 3196 up and down, and the extrusion cylinder 3195 will be used to extrude and feed the raw materials in the distribution pipe 319. At the same time, gas will flow out of the circular hole to assist in feeding and improve the efficiency of grinding.

[0052] like Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, a cone 3198 is fixedly connected to the bottom end of the extrusion cylinder 3195 , a circular hole is opened on the extrusion cylinder 3195 , a stopper 3197 is arranged at the lower opening of the circular hole, and air holes are opened on the blades of the rotating wheel 3194 .

The one-way valve 3281 can limit the flow direction of the gas, so that the gas flows from the upper part of the housing 200 to the lower part, passes through the second collection frame 3282 and the cylinder 324, and then enters the material distribution pipe 319, and the guide arc plate 3231 can increase the stability of the operation of the cam 323.

The rotation gap of the rotating wheel 3194 is used to move the arc ring 3196 up and down, and the extrusion cylinder 3195 is used to extrude and feed the raw materials in the distribution pipe 319. At the same time, gas will flow out of the circular hole to assist in feeding and improve the efficiency of grinding. The block 3197 can reduce the reflux of the meal replacement powder, and the air hole can exhaust when there is a lot of gas, thereby ensuring the stability of the rotation of the rotating wheel 3194.

[0056] Working principle: Place the food to be processed in the feeding frame first, and the material will enter between the rotating grinding disc 311 and the fixed grinding disc 310 from the circular tube 312 and the feeding channel, start the first motor 313, and under the action of the two bevel gears 314, the rotating grinding disc 311 rotates, and the meal replacement powder after preliminary grinding will fall onto the sieve plate 320 under the action of gravity, and the larger particles of meal replacement powder will follow the sieve plate 320 to reach the strip frame 210, and the sieved meal replacement powder will pass through the upper sieve 321 to reach the guide plate 3201, and under its guidance, it will be filtered through the lower sieve 321, and the qualified meal replacement powder will pass through the lower sieve 321 to reach the second collection frame 32 82, those that do not meet the specifications will be guided into the first collection frame 3206 through the lower screen 321 and the lower hopper 3205. The meal replacement powder that does not meet the specifications in the first collection frame 3206 will be put into the distribution hopper 318, and the second motor 3181 will drive the rotating distribution plate 3183 to rotate, and the material will automatically enter the upper discharge hole 3184. During rotation, when the discharge hole 3184 moves to the arc plate 3185 area, the upper feeding is stopped, and the upper and lower discharge holes 3184 will overlap at the same time, and the meal replacement powder will enter the distribution pipe 319 from the discharge pipe 3191, and enter the two grinding components to grind the meal replacement powder according to grades. The larger specifications are re-added and ground at the large particle grinding component.

[0057] At the same time, during the above grinding process, it is necessary to start the fourth motor 322, and use the rotation of the cam 323 to drive the screen plate 320 to move up and down reciprocatingly. First, use the first connecting rod 3202, the first spring 3203 and the second connecting rod 3204 to drive the screen plate 320 to reciprocate for efficient screening;

[0058] Second, the cam 323 will synchronously squeeze the contact plate 327 when rotating. Under the action of the second spring 325, the piston rod 326 will reciprocate in the cylinder 324. Under the action of the two one-way valves 3281, the gas at the bottom of the second collection frame 3282 will be extracted, and an air duct will be formed in the shell 200. The gas in the upper part of the shell 200 will flow to the lower area to form a predetermined ventilation duct, and the meal replacement powder that meets the specifications will be stored in the second collection frame 3282 by using the ventilation duct;

[0059] 3. The gas in the cylinder 324 will enter the installation frame 3193 through the three-way pipe 3192. The gas will blow the rotating wheel 3194 to rotate. The rotation gap of the rotating wheel 3194 will be used to reciprocate the arc ring 3196 up and down. The extrusion cylinder 3195 will be used to extrude and feed the raw materials in the distribution pipe 319. At the same time, gas will flow out of the circular hole to assist in feeding and improve the efficiency of grinding.

[0060] It should be noted that the first motor 313, the third motor 315, the second motor 3181, the fourth motor 322, the one-way valve 3281, etc. in the above description are all relatively mature devices in the existing technology. The specific models can be selected according to actual needs. At the same time, the first motor 313, the third motor 315, the second motor 3181, and the fourth motor 322 can be powered by a built-in power supply or by AC power.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
