DETAILED DESCRIPTION

[0017] The present invention will be further described below in conjunction with the accompanying drawings: The directional nouns involved in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application according to the visual orientation shown in the accompanying drawings. Unless otherwise clearly specified and limited, the terms "setting", "installation", "connection", etc. should be understood in a broad sense. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0018] like Figure 1 and Figure 2As shown, a multi-stage grinding device for processing corn starch includes a box body 100, a driving mechanism 200, a primary grinding mechanism 300, a secondary grinding mechanism 400, a tertiary grinding mechanism 500, and a material spreading mechanism 600. The primary grinding mechanism 300, the secondary grinding mechanism 400, and the tertiary grinding mechanism 500 are sequentially installed in the box body 100 from top to bottom, and the three are connected in sequence; the material spreading mechanism 600 is installed above the primary grinding mechanism 300, and the side facing away from the primary grinding mechanism 300 is connected to the outside of the box body 100; the driving mechanism 200 is composed of a swing plate 220 and a shaft rod 230, and is installed on one side of the secondary grinding mechanism 400, and one end of the swing plate 220 is movably connected to the primary grinding mechanism 300, and the other end is movably connected to the tertiary grinding mechanism 500; the shaft rod 230 is installed at one end of the swing plate 220, and the end facing away from the swing plate 220 passes through the secondary grinding mechanism 400 and is connected to the material spreading mechanism 600. In this way, driven by the driving mechanism 200, the first-stage grinding mechanism 300, the second-stage grinding mechanism 400, the third-stage grinding mechanism 500 and the spreading mechanism 600 can be driven to operate simultaneously. Compared with the traditional working mode of multiple grinding equipment in series, it not only effectively reduces the occupied space of the grinding equipment, but also enables a set of driving mechanism 200 in a set of equipment to complete the multi-stage grinding of corn starch. While improving work efficiency, it also reduces production costs.

[0019] Optionally, the driving mechanism 200 further includes a driving motor 210 installed at one end of the wobble plate 220 away from the shaft 230 , and configured to drive the wobble plate 220 to rotate.

[0020] Optionally, a feed hopper 101 is provided on the top of the box body 100, and a discharge hopper is provided on the adjacent side wall.

[0021] like Figure 3 and Figure 4As shown, the wobble plate 220 includes a wobble plate body 221, a sleeve 225, and a swing connection block 226. One end of the wobble plate body 221 is provided with a chamfered surface 222, and an oil storage tube column 224 is provided at the center of the chamfered surface 222, and a sliding groove 223 surrounding the oil storage tube column 224 and the chamfered surface 222 is provided at the connection point thereof; the sleeve 225 is sleeved on the end of the oil storage tube column 224 away from the wobble plate body 221, and the end of the sleeve 225 facing the wobble plate body 221 is provided with a chamfered surface 222 and a sliding groove 223 identical to those of the wobble plate body 221; a plurality of swing connection blocks 226 are provided, which are symmetrically embedded in the sliding groove 223 provided between the wobble plate body 221 and the sleeve 225, and one side of the swing connection block 226 is in contact with the oil storage tube column 224, and the other side is provided with a connecting column 227 for connecting the primary grinding mechanism 300 or the tertiary grinding mechanism 500. In this way, the chamfered surface 222 provided on the wobble plate body 221 cooperates with the chamfered surface 222 provided on the sleeve 225, so that the gap between the two chamfered surfaces 222 forms an oblique annular groove 240 surrounding the oil storage pipe column 224. When the swing connection block 226 is inserted into the oblique annular groove 240, both ends of the swing connection block 226 are simultaneously inserted into the sliding grooves 223 provided on the wobble plate body 221 and the sleeve 225, which plays a limiting role on the swing connection block 226. At the same time, the swing connection block 226 is connected to the primary grinding mechanism 300 or the tertiary grinding mechanism 500 through the provided connecting column 227, so that the swing connection block 226 and the wobble plate 220 are relatively fixed. When the driving motor 210 drives the swing plate 220 to rotate, the swing connecting block 226 is limited by the primary grinding mechanism 300 or the tertiary grinding mechanism 500 and the sliding groove 223, so that the swing connecting block 226 can swing along the oblique annular groove 240 between the swing plate body 221 and the sleeve 225, and at the same time drive some components of the primary grinding mechanism 300 and / or the secondary grinding mechanism 400 connected thereto to make reciprocating motion, thereby achieving the purpose of grinding corn starch.

[0022] like Figure 5As shown, the inside of the swing plate body 221 and the oil storage column 224 are provided with a cavity 2241 that is connected to each other, and the cavity 2241 is provided with an opening at one end facing the swing plate body 221, and a sealing plate 2211 connected to the swing plate body 221 is installed at the edge of the opening; an oil injection hole 2244 that is connected to the cavity 2241 is drilled on the outer wall of the swing plate body 221, and a sealing plug 2243 is installed in the oil injection hole 2244; an oil brush 2242 is embedded on the side wall of the oil storage column 224, and one side of the oil brush 2242 is intermittently in contact with one side of the swing connection block 226, and the other side is connected to the cavity 2241. In this way, because the oblique annular groove 240 between the swing plate body 221 and the sleeve 225 is an open structure, and under the action of centrifugal force, the lubricating grease cannot be stored well. In order to prevent the swing connection block 226 from dry grinding when it moves in the oblique annular groove 240, lubricating grease is filled into the cavity 2241 between the oil storage column 224 and the swing plate body 221. Under the action of centrifugal force, the lubricating grease is absorbed by the oil brushing cotton 2242 and penetrates to the side facing the swing connection block 226. When the swing connection block 226 contacts the oil brushing cotton 2242, the oil brushing cotton 2242 can evenly brush the absorbed lubricating grease on the side in contact with the swing connection block 226, so that the swing connection block 226 and the side wall of the oil storage column 224, the side wall of the sliding groove 223 provided in the swing plate body 221, and the side wall of the sliding groove 223 provided in the sleeve 225 are lubricated, and dry grinding is avoided, thereby improving the overall service life of the swing connection block 226, the swing plate body 221 and the sleeve 225. At the same time, when the lubricating grease needs to be replaced, the lubricating grease in the cavity 2241 can be quickly replaced by removing the sealing plate 2211. In addition, in daily maintenance, the lubricating grease can be added to the cavity 2241 through the oil filling hole 2244 by removing the sealing plug 2243, thereby effectively improving the work efficiency of the maintenance of the lubricating grease.

[0023] like Figure 6As shown, the secondary grinding mechanism 400 includes a cylinder 401, a support frame 404, a grinding sleeve 410, and a grinding roller 420. The side wall of the cylinder 401 is provided with a first connecting groove 402 and a second connecting groove 403, and the first connecting groove 402 and the second connecting groove 403 are arranged opposite to each other; the grinding sleeve 410 is embedded in the cylinder 401, and a plurality of supporting plates 411 are installed between the inner wall of the cylinder 401 and the outer wall of the grinding sleeve 410; the grinding roller 420 is rotatably installed in the grinding sleeve 410, and the grinding roller 420 is connected to the shaft 230. In this way, the cylinder 401 is located between the primary grinding mechanism 300 and the tertiary grinding mechanism 500, and can provide stable support to the primary grinding mechanism 300 and the tertiary grinding mechanism 500 through the support frame 404 arranged on its side wall, so that the grinding roller 420 can remain stable when performing grinding work with the grinding sleeve 410 driven by the shaft 230, and is not easy to be displaced or separated from the primary grinding mechanism 300 and / or the tertiary grinding mechanism 500 due to vibration.

[0024] Optionally, a plurality of positioning blocks 4021 are provided on the side walls of the first communicating groove 402 and the second communicating groove 403. In this way, the positioning blocks 4021 can accurately dock with the primary grinding mechanism 300 and the secondary grinding mechanism 400.

[0025] Optionally, a detachable inspection plate 405 is installed at one end of the cylinder 401 .

[0026] like Figure 7 As shown, the grinding roller 420 is composed of an axis tube 421, a support rod 422, and a grinding strip 423. There are a plurality of grinding strips 423, which are arranged around the axis tube 421 in an equidistant manner, and a plurality of support rods 422 are installed between the grinding strips 423 and the axis tube 421. In this way, the grinding strips 423 are connected to the axis tube 421 through the support rods 422, so that there is a gap between the grinding strips 423 and the axis tube 421. When the grinding strips 423 rotate with the axis tube 421, the grinding strips 423 can achieve the effect of grinding and stirring at the same time, so that the raw materials in the grinding sleeve 410 are not easy to agglomerate, and can easily enter between the grinding sleeve 410 and the grinding roller 420 for grinding.

[0027] like Figure 8As shown, the primary grinding mechanism 300 includes a first frame 301, a first static grinding plate 307, a first dynamic grinding assembly 310, and a first linkage bridge rod 313. The first frame 301 is provided with a mounting groove 302 extending from one side to the other side, and a strip-shaped discharge groove 305 is provided at an adjacent position of the mounting groove 302; a slide groove 308 is further provided at the opposite edge of one side of the first frame 301, and is located on both sides of the mounting groove 302; the first dynamic grinding assembly 310 is movably mounted on the first frame 301 On one side, a slide rail 311 adapted to the slide slot 308 is provided on the side wall of the first dynamic grinding assembly 310; the first dynamic grinding assembly 310 is also provided with a plurality of collecting hoppers 312 connected to the first frame 301, and a grinding block 3122 is installed at the bottom of each collecting hopper 312; the first static grinding plate 307 is embedded in the installation slot 302 from one side of the first frame 301; one end of the first linkage bridge rod 313 is fixedly connected to the first dynamic grinding assembly 310, and the other end is connected to the connecting column 227. In this way, the first dynamic grinding assembly 310 cooperates with the slide slot 308 through the slide rail 311, so that the first dynamic grinding assembly 310 can stably reciprocate between the first frame 301. After the first linkage bridge rod 313 cooperates with the connecting column 227 and is connected to the swing connecting block 226, the first dynamic grinding assembly 310 can quickly reciprocate on one side of the first frame 301 under the drive of the driving motor 210. As a result, the raw materials are evenly scattered from the collecting hopper 312 between the first dynamic grinding component 310 and the first static grinding plate 307. Under the reciprocating motion of the first dynamic grinding component 310, the raw materials can be continuously kneaded and ground until the diameter of the raw materials is equal to or less than the gap distance between the first dynamic grinding component 310 and the first static grinding plate 307, and then discharged from the strip discharge trough 305 and enter the secondary grinding mechanism 400 for the next stage of grinding.

[0028] Optionally, a plurality of brackets 303 are installed at the edge of the mounting groove 302 provided in the first frame 301 to support the first static grinding plate 307. In this way, with the support of the brackets 303, the first static grinding plate 307 can be stably maintained at a specified height during the grinding operation, so that the gap between the first static grinding plate 307 and the first dynamic grinding assembly 310 is not easy to change, thereby improving the grinding accuracy of the raw material.

[0029] Optionally, a plurality of oppositely mounted collecting plates 304 are further provided below the bracket 303, and a discharge slot 306 adapted to the first connecting slot 402 is reserved between the collecting plates 304. In this way, the raw materials ground by the primary grinding mechanism 300 can accurately enter the first connecting slot 402 through the discharge slot 306.

[0030] like Fig. 9 As shown, a transverse plate 3121 is fixed to the side of the collecting hopper 312 facing the first static grinding plate 307, and a grinding block 3122 is installed on the side of the transverse plate 3121 facing the first static grinding plate 307; a longitudinal fixing rod 3123 is installed between the transverse plate 3121 and the grinding block 3122. In this way, the grinding block 3122 can be stably fixed to the side of the collecting hopper 312 facing the first static grinding plate 307 under the cooperation of the longitudinal fixing rod 3123 and the transverse plate 3121. At the same time, a triangular structure is formed between the grinding block 3122 and the collecting hopper 312, which effectively improves the structural strength of the first dynamic grinding assembly 310, making it less likely to deform under the action of external force during the grinding process, which not only improves the grinding fineness of the raw materials, but also improves the overall service life of the primary grinding mechanism 300.

[0031] like Fig.10As shown, the three-stage grinding mechanism 500 includes a second frame 510, a second static grinding plate 520, a second dynamic grinding assembly 530, a discharge bottom plate 540, and a second linkage bridge rod 531. The second frame 510 is arranged below the secondary grinding mechanism 400, and the two are connected to each other. The discharge bottom plate 540 is fixed on the side of the second frame 510 facing away from the secondary grinding mechanism 400. The second dynamic grinding assembly 530 is movably connected with the second frame 510 and arranged between the second frame 510 and the discharge bottom plate 540, and a plurality of strip grooves 532 are arranged on the second dynamic grinding assembly 530. The second static grinding plate 520 is embedded in the second frame 510 from one side of the second frame 510, and is located between the second frame 510 and the second dynamic grinding assembly 530. One end of the second linkage bridge rod 531 is fixedly connected with the second dynamic grinding assembly 530, and the other end is movably connected with the connecting column 227. In this way, the structure and operation mode of the three-stage grinding mechanism 500 are basically the same as those of the first-stage grinding mechanism 300. The raw material ground by the secondary grinding mechanism 400 enters between the second static grinding plate 520 and the second dynamic grinding assembly 530 through the second frame 510 connected to the second connecting groove 403. The second dynamic grinding assembly 530 is connected to the connecting column 227 through the second linkage bridge rod 531, and reciprocates in the second frame 510 driven by the driving motor 210. The raw material between the second static grinding plate 520 and the second dynamic grinding assembly 530 is kneaded and ground to further reduce the volume of the raw material. When the raw material is ground to a preset volume, it is scattered onto the surface of the discharge bottom plate 540 through the strip groove 532. Under the vibration of the operation of the tertiary grinding mechanism 500, the discharge bottom plate 540 gradually discharges the processed raw materials out of the equipment. Compared with the primary grinding mechanism 300, the distance between the second static grinding plate 520 and the second dynamic grinding assembly 530 of the tertiary grinding mechanism 500 and the grinding particles on their surfaces are smaller than the distance between the first static grinding plate 307 and the first dynamic grinding assembly 310 and the grinding particles therebetween.

[0032] Optionally, a feeding groove 511 adapted to the second connecting groove 403 is provided on a side of the second frame 510 facing the secondary grinding mechanism 400 .

[0033] Optionally, a plurality of material passages 521 are provided on one side of the second static grinding plate 520 and extend to the other side. In this way, the raw materials entering the feed slot 511 will not be blocked by the second static grinding plate 520 through the material passages 521, so that the raw materials can smoothly enter between the second static grinding plate 520 and the second dynamic grinding assembly 530.

[0034] Optionally, a plurality of fixing plates 512 for connecting to a discharge bottom plate 540 are installed on the side wall of the second frame 510 .

[0035] like Fig.11 and Fig.12 As shown, the material spreading mechanism 600 includes a fixed side plate 611, a vibration plate 612, a spring rod 615, a cam 617, a rolling wheel 620, a partition plate 630, a suspension rod 631, and a swing bucket 640. The fixed side plate 611 is fixedly connected to the inner wall of the box body 100, and the vibration plate 612 is movably connected to the fixed side plate 611. The two are perpendicular to each other, and a plurality of coil springs 613 are installed at the connection between the two. The spring rod 615 is provided with a plurality of spring rods, one end of which is fixedly connected to the vibration plate 612, and the other end is fixedly connected to the inner wall of the box body 100. The partition plate 630 is arranged at one end of the vibration plate 612 away from the fixed side plate 611; and the partition plate 630 is arranged at one end of the vibration plate 612 away from the fixed side plate 611. A plurality of suspension rods 631 are provided on one side of the partition plate 630, one end of which is fixedly connected to the partition plate 630 and the other end is fixedly connected to the inner wall of the box body 100; the rolling wheel 620 is provided on one side of the vibration plate 612, and rollers 616 connected to the box body 100 are protruded from both ends of the rolling wheel 620; the cam 617 is installed at both ends of the rolling wheel 620 and is fixedly connected to the rollers 616, and the cam 617 is in intermittent contact with the vibration plate 612; the swing bucket 640 is movably installed on one side of the partition plate 630, and the swing bucket 640 is connected to the other side of the partition plate 630; and protruding rods 641 are also provided at both ends of the swing bucket 640. In this way, the cam 617 and the rolling wheel are connected to the driving mechanism 200 through the rollers 616, and rotate at a uniform speed under the drive of the driving mechanism 200. During the rotation of the cam 617, the outer side wall of the cam 617 intermittently contacts the vibration plate 612. When the cam 617 contacts the vibration plate 612, the vibration plate 612 is offset in the direction away from the rolling wheel 620. When the cam 617 is separated from the vibration plate 612, the vibration plate 612 rebounds rapidly under the action of the coil spring 613 and the spring rod 615. Therefore, under the influence of the cam 617, the vibration plate 612 is always in a regular up and down vibration. On the one hand, the raw material can be moved toward the partition plate 630 by the vibration force. On the other hand, the cutting force of the rolling wheel 620 on the raw material can be increased by relying on the rebound force of the vibration plate 612, thereby improving the effective cutting ability of the rolling wheel 620 on the raw material. The cut raw material falls into the swing bucket 640 installed under the partition plate 630 by the vibration force. The swing bucket 640 is connected to the driving mechanism 200 via a protruding rod 641. Driven by the driving mechanism 200, the swing bucket 640 swings regularly, thereby evenly scattering the raw materials in the swing bucket 640 onto the surface of the primary grinding mechanism 300, so that the primary grinding mechanism 300 can evenly grind the raw materials.

[0036] Optionally, a raised side strip 614 is provided at the edge of the vibration plate 612. Thus, the side strip 614 can increase the contact distance between the vibration plate 612 and the cam 617, thereby increasing the amplitude of the vibration plate 612. At the same time, the side strip 614 can also guide the moving direction of the raw material.

[0037] like Fig.13 As shown, the side wall of the wheel body 6171 of the cam 617 is provided with synapses 6172 arranged around it and at equal intervals, and the synapses 6172 are embedded with rollers 6173. In this way, the synapses 6172 arranged at equal intervals can intermittently contact with the edge strip 614 as the cam 617 rotates, so as to provide vibration force to the vibration plate 612. At the same time, the friction between the synapses 6172 and the edge strip 614 can be reduced by the provided rollers 6173, and the impact force of intermittent contact can also be reduced, so that the service life of the cam 617 and the edge strip 614 can be effectively improved.

[0038] Optionally, a material laying slot 632 communicating with the swing bucket 640 is provided on one side of the partition plate 630 facing the vibration plate 612. In this way, the raw materials can enter the swing bucket 640 without being hindered by the partition plate 630.

[0039] like Fig.14 As shown, rotating frames 642 are further provided at both ends of the swing bucket 640, and the rotating frames 642 are fixedly connected to the partition plate 630. In this way, the swing bucket 640 is limited by the rotating frames 642, so that the swing bucket 640 can swing with the rotating frames 642 as the axis, so that the swing bucket 640 is not easy to deviate or fall off during the swinging process. Therefore, the operation stability of the swing bucket 640 is improved.

[0040] like Fig.15 As shown, the side wall of the rolling wheel 620 is provided with elastic steel sheets 621 and cutters 622 arranged at intervals. In this way, the length of the elastic steel sheet 621 is greater than the interval between the elastic steel sheet 621 and the vibration plate 612, so that the elastic steel sheet 621 will deform when in contact with the vibration plate 612, and recover when separated from the vibration plate 612. Through the deformation of the elastic steel sheet 621, on the one hand, it can squeeze the raw material, and on the other hand, it can fix the raw material, so that the cutter 622 can cut the raw material, so that the raw material is not easy to splash when cutting.

[0041] like Fig.16As shown, it also includes a linkage wheel group 700, which consists of a driving wheel 710, a swing bearing 712, a linkage rod 713, a linkage wheel 714, and a linkage belt 715. The driving wheel 710 is connected to one end of the shaft 230 and is located on one side of the secondary grinding mechanism 400, and an eccentric shaft 711 is provided on the side of the driving wheel 710 that is away from the shaft 230; the linkage wheel 714 is installed at the end of one of the rollers 616 and is on the same horizontal plane as the driving wheel 710, and a linkage belt 715 is sleeved between the driving wheel 710 and the linkage wheel 714; the swing bearing 712 is installed at one end of the protruding rod 641; one end of the linkage rod 713 is rotatably connected to the eccentric shaft 711, and the other end is rotatably connected to the swing bearing 712. In this way, while the driving wheel 710 drives the rolling wheel 620 and the cam 617 to operate through the cooperation of the linkage belt 715 and the linkage wheel 714, it also drives the swing bucket 640 to swing regularly through the cooperation of the eccentric shaft 711 and the linkage rod 713. Thus, the purpose of driving multiple mechanisms to be linked by one set of driving mechanisms 200 is achieved through the linkage wheel set 700, which not only improves the working efficiency of the equipment, but also improves the working efficiency of the driving mechanism 200.

[0042] Finally, although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
