Description

Technical Field

[0001] The invention relates to the technical field of starch grinding devices, in particular to refined grinding equipment for corn starch production. Background Art

[0002] Corn starch has strong water absorption and certain antioxidant properties. It can adjust the viscosity of food, improve the taste of food, and delay the decomposition and deterioration of food. It is widely used in food, sugar making, fermentation, medicine, chemical industry and other fields.

[0003] Corn starch grinding mostly refers to the grinding of corn slurry, which is the endosperm that has been broken and separated, and is composed of starch granules, gluten, seed coat, and endosperm particles containing a large amount of starch. The grinding of the slurry needs to go through a fine grinding process, the purpose of which is to make the endosperm particle size finer, while releasing the starch associated with protein and cellulose to a certain extent, creating conditions for the separation of the next process. Existing corn starch grinding devices mostly use a single method or a single action for grinding, and the corn starch slurry cannot be added slowly and evenly during the grinding action, resulting in uneven grinding and poor grinding quality. Summary of the invention

[0004] The purpose of the present invention is to provide a refined grinding equipment for corn starch production, which utilizes a fine grinding component and a primary grinding component arranged in a main shell, in conjunction with an automatically opened and closed top cover body and a safety transmission component, to form a dual and different grinding action.

[0005] The object of the present invention is achieved through such a technical solution, a refined grinding device for corn starch production, comprising a chassis component, a top cover component, a fine grinding component, a primary grinding component and a safety transmission component;

[0006] The chassis component includes a main shell, the top cover assembly includes a top cover body, the fine grinding assembly includes fine grinding teeth, the primary grinding assembly includes a primary grinding solid cover, a material drop funnel and a reset slide column, and the safety transmission component includes a transmission gear, a transmission connection toothed belt wheel and a transmission connection toothed belt;

[0007] The top cover body is screwed to the top opening of the main housing, the two outer sides of the main housing are fixed with electric cylinder fixed seats, the two outer sides of the top cover body are fixed with electric cylinder movable seats, the bottom body of the telescopic electric cylinder is rotatably connected to the electric cylinder fixed seat, and the top end of the telescopic rod of the telescopic electric cylinder is rotatably connected to the electric cylinder movable seat;

[0008] The inner lower end of the main body of the main shell is laterally screwed with a fine grinding shaft, the fine grinding teeth are arranged and fixed on the outside of the fine grinding shaft, the primary grinding solid cover is fixed to the inner upper end of the main shell, the blanking funnel is laterally screwed in the primary grinding solid cover, the inner bottom surface of the primary grinding solid cover is arranged and fixed with a solid grinding seat, the outer bottom surface of the blanking funnel is arranged and fixed with a dynamic grinding seat, the middle part of the outer side surface of the main shell is screwed with a central gear, the outer end of the rotating shaft of the blanking funnel is fixed with a blanking swing connecting rod, the eccentric end of the central gear is slidably connected with the blanking swing connecting rod, and the outer side surface of the main shell is also obliquely elastically slid with a reset slide rod, and the reset slide rod is slidably connected with the blanking swing connecting rod through a reset slide column;

[0009] The transmission gear is screwed on one end of the outer side surface of the main shell and is connected to the precision grinding shaft. An electric cylinder seat is fixed to the bottom end of the main body of one group of telescopic electric cylinders, and transmission connecting shafts are screwed on both sides of the main body of the electric cylinder seat. A transmission connecting gear is fixed to the inner end of each group of transmission connecting shafts. The transmission connecting toothed belt pulley is plugged and fixed on the outer end of the transmission connecting shaft, and the transmission connecting toothed belt is sleeved and installed between the transmission connecting toothed belt pulleys.

[0010] The use process of the technical solution of the present invention is as follows:

[0011] The blanking funnel is a funnel-shaped structure. When the top cover is opened, the central gear cannot form an effective transmission connection with the transmission gear. Under the action of the elastic support of the reset slide rod itself, the sliding connection formed by the reset slide column and the blanking swing link can drive the top opening of the blanking funnel to tilt toward the top side of the main shell, thereby facilitating the addition of corn starch slurry into the blanking funnel.

[0012] During the process of adding starch slurry, a small amount of starch slurry is allowed to enter the inner cavity of the main shell through the narrow passage in the middle of the feeding funnel and the through hole of the primary grinding solid cover. At this time, the fine grinding teeth are in a high-speed rotating state and can be ground.

[0013] After the starch slurry is added, the top cover body is automatically closed. As the top cover body is closed in place, the fixed rotating seat and the initial grinding solid cover can form a closed inner cavity, and in the process of the telescopic electric cylinder driving the top cover body to close, the telescopic electric cylinder body itself can be rotated, thereby driving the rotation of the electric cylinder seat. After the top cover body is closed in place, one set of transmission connecting gears can be meshed with the transmission gear, and synchronously, the other set of transmission connecting gears can be meshed with the center gear, so that only after the top cover body is closed in place, the transmission gear can form an effective transmission connection with the center gear. At this time, the fine grinding shaft can drive the rotation of the fine grinding teeth on the one hand to perform fine grinding, and on the other hand to drive the rotation of the transmission gear. The transmission gear can drive the rotation of another set of transmission connecting gears through the cooperation formed by the transmission connection toothed belt wheel and the transmission connection toothed belt, so that the center gear forms a slowly rotating state, thereby providing power for the sliding cooperation formed by the eccentric column and the blanking swing connecting rod;

[0014] The transmission mechanism can drive the rotation of the central gear. The sliding connection formed by the eccentric end of the central gear and the blanking swing connecting rod can make the blanking swing connecting rod overcome the elastic thrust of the reset slide rod and swing back and forth within a certain range, thereby driving the blanking funnel to swing back and forth.

[0015] The reciprocating swing of the blanking funnel can not only make the starch slurry contained in the blanking funnel leak out from the through hole at the bottom of the blanking funnel at a uniform and slow speed, but also make the dynamic grinding seat and the fixed grinding seat fixed on the inner bottom surface of the primary grinding solid cover form a primary grinding action;

[0016] After primary grinding, the starch slurry can enter the coverage area of ​​the fine grinding teeth in the inner cavity of the main shell through the through hole on the bottom surface of the primary grinding solid cover, and is finely crushed and ground by the fine grinding teeth.

[0017] By adopting the above technical solution, the present invention can achieve the following beneficial effects:

[0018] (1) The present invention is based on the primary grinding solid cover fixed at the upper end of the main shell body, and divides the inner cavity of the main shell body into two parts: a primary grinding cavity and a fine grinding cavity. A blanking funnel is horizontally screwed inside the primary grinding solid cover for holding the corn starch slurry to be ground, and a blanking swing connecting rod is fixed to the outer end of the rotating shaft of the blanking funnel. Not only the eccentric end of the central gear is slidably connected to the blanking swing connecting rod, but also the reset slide column fixed on the inner side of the reset slide rod in the elastic sliding support state is also slidably connected to the blanking swing connecting rod. The purpose is to enable the upper end opening of the blanking funnel to be tilted toward the side of the top opening of the main shell body when the central gear is in a free rotation state, so as to facilitate and safely add corn starch slurry into the blanking funnel;

[0019] (2) The opening and closing action of the top cover body itself is not only to cooperate with the main shell body to form a closed cavity, but also to enable the transmission gear and the center gear to form an effective transmission connection after the top cover body is closed in place. Since the transmission gear is connected to the fine grinding shaft, the fine grinding shaft can rotate and drive the fine grinding teeth to rotate at the same time, and synchronously drive the rotation of the center gear, so that the eccentric end of the center gear forms a sliding fit with the blanking swing connecting rod, driving the blanking swing connecting rod to swing back and forth. The reciprocating swinging action formed by the blanking swing connecting rod to drive the blanking funnel can not only make the corn starch slurry in the blanking funnel enter the inner cavity of the primary grinding solid cover at a uniform speed, but also drive the dynamic grinding seat and the solid grinding seat to form a grinding action, so that the purpose of fine grinding of corn starch can be achieved through the synchronous double grinding action.

[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0038] like Figure 1-Figure 13 A refined grinding device for corn starch production is shown; the top cover 201 is screwed to the top opening of the main housing 102, the two outer side surfaces of the main housing 102 are fixed with electric cylinder fixed seats 204, the two outer side surfaces of the top cover 201 are fixed with electric cylinder movable seats 205, the bottom body of the telescopic electric cylinder 206 is rotatably connected to the electric cylinder fixed seat 204, and the top end of the telescopic rod of the telescopic electric cylinder 206 is rotatably connected to the electric cylinder movable seat 205;

[0039] Driven by the two sets of telescopic electric cylinders 206, the top cover body 201 can be opened and closed stably;

[0040] The inner lower end of the main body of the main shell 102 is laterally screwed with a fine grinding shaft 302, and the fine grinding teeth 303 are arranged and fixed on the outside of the fine grinding shaft 302. The primary grinding cover 401 is fixed to the inner upper end of the main shell 102. The blanking funnel 406 is laterally screwed in the primary grinding cover 401. The inner bottom surface of the primary grinding cover 401 is arranged and fixed with a solid grinding seat 403. The outer bottom surface of the blanking funnel 406 is arranged and fixed with a dynamic grinding seat 419. The adjacent dynamic grinding seat 419 can form a grinding action with the solid grinding seat 403. The central gear 409 is screwed in the middle of the outer side surface of the main shell 102. The blanking funnel 406 A blanking swing link 411 is fixed to the outer end of the rotating shaft, and the eccentric end of the central gear 409 is in sliding connection with the blanking swing link 411. The outer side surface of the main housing 102 is also obliquely elastically slid with a reset slide 414, and the reset slide 414 is in sliding connection with the blanking swing link 411 through a reset slide column 417. Under the elastic thrust of the reset slide 414 itself, when there is no external force pushing, the top end of the blanking funnel 406 can be obliquely directed toward one side of the main housing 102, so that it is convenient to add the corn starch slurry to be ground into the blanking funnel 406 when the top cover 201 is opened;

[0041] The transmission gear 607 is screwed on one end of the outer side surface of the main shell 102 and is connected to the grinding shaft 302 in transmission. An electric cylinder seat 608 is fixed to the bottom end of the main body of one group of telescopic electric cylinders 206. Transmission connecting shafts 609 are screwed on both sides of the main body of the electric cylinder seat 608. A transmission connecting gear 610 is fixed to the inner end of each group of transmission connecting shafts 609. A transmission connecting toothed belt pulley 611 is plugged and fixed on the outer end of the transmission connecting shaft 609. A transmission connecting toothed belt 612 is sleeved and installed between the transmission connecting toothed belt pulleys 611.

[0042] Here’s how it works:

[0043] Before the equipment starts grinding, the top cover 201 needs to be opened first, and the rotary drive mechanism connected to the lapping shaft 302 needs to be started, so that the lapping teeth 303 are in a high-speed working state;

[0044] The blanking funnel 406 is a funnel-shaped structure. When the top cover 201 is opened, the central gear 409 cannot form an effective transmission connection with the transmission gear 607. Under the elastic support of the reset slide rod 414 itself, the sliding connection formed by the reset slide column 417 and the blanking swing link 411 can drive the top opening of the blanking funnel 406 to tilt toward the top side of the main shell 102, so as to facilitate the addition of corn starch slurry into the blanking funnel 406.

[0045] And because the middle part of the material dropping funnel 406 is a narrow passage, the added corn starch slurry can be accumulated in the upper part of the material dropping funnel 406;

[0046] During the process of adding starch slurry, a small amount of starch slurry is allowed to enter the inner cavity of the main housing 102 through the narrow passage in the middle of the feeding funnel 406 and the through hole of the primary grinding solid cover 401. At this time, the fine grinding teeth 303 are in a high-speed rotating state, and can be ground.

[0047] After the starch slurry is added, the top cover 201 is automatically closed. As the top cover 201 is closed, the fixed rotating seat 202 and the initial grinding fixed cover 401 form a closed inner cavity. In the process of the telescopic electric cylinder 206 driving the top cover 201 to close, the main body of the telescopic electric cylinder 206 can rotate, thereby driving the rotation of the electric cylinder connecting seat 608. After the top cover 201 is closed, one set of transmission connecting gears 610 can be meshed with the transmission gear 607, and synchronously, the other set of transmission connecting gears 610 can be meshed with the central gear 409, so that only when the top cover 201 is closed, the transmission connecting gear 610 can be meshed with the central gear 409. After being fully closed, the transmission gear 607 can form an effective transmission connection with the center gear 409. At this time, the lapping shaft 302 can drive the lapping teeth 303 to rotate on the one hand to perform fine grinding, and on the other hand drive the transmission gear 607 to rotate. The transmission gear 607 can drive another set of transmission connection gears 610 to rotate through the cooperation formed by the transmission connection toothed belt wheel 611 and the transmission connection toothed belt 612, so that the center gear 409 forms a slow rotation state, thereby providing power for the sliding cooperation formed by the eccentric column 410 and the blanking swing connecting rod 411;

[0048] The transmission mechanism can drive the rotation of the central gear 409. The sliding connection formed between the eccentric end of the central gear 409 and the blanking swing link 411 can make the blanking swing link 411 overcome the elastic thrust of the reset slide bar 414 and swing back and forth within a certain range, thereby driving the blanking funnel 406 to swing back and forth.

[0049] The reciprocating swing of the blanking funnel 406 can not only make the starch slurry contained in the blanking funnel 406 leak out from the through hole at the bottom of the blanking funnel 406 at a uniform and slow speed, but also make the dynamic grinding seat 419 and the fixed grinding seat 403 fixed on the inner bottom surface of the primary grinding solid cover 401 form a primary grinding action;

[0050] The starch slurry after primary grinding can enter the coverage area of ​​the fine grinding teeth 303 in the inner cavity of the main shell 102 through the through hole on the bottom surface of the primary grinding solid cover 401, and is finely crushed and ground by the fine grinding teeth 303.

[0051] The specific structure of the chassis component 1 and the top cover component 2 is as follows Figure 2 and Figure 3As shown, the main housing 102 is fixedly connected to one side of the bottom frame 101, and the discharge hopper 103 is connected to the bottom end of the main housing 102 and communicated with the inner cavity of the main housing 102;

[0052] The discharge hopper 103 is a corner tilted structure, which facilitates the corn starch to be discharged at a uniform and slow speed after the grinding work is completed;

[0053] The top cover 201 is screwed to the fixed screw seat 202 at one side of the outer end of the main housing 102 through the movable screw seat 203 at one side of the outer end;

[0054] The specific structure of the fine grinding component 3 is as follows Figure 4 As shown, the lapping rotary seat 301 is coaxially symmetrically fixedly installed at the bottom ends of the two side surfaces of the main housing 102, the two ends of the lapping shaft 302 are respectively rotatably connected in the lapping rotary seat 301, the lapping pulley 305 is plugged and fixed on the outer side of one end of the lapping shaft 302, and a driving motor 306 is fixedly installed on the top of the other side of the bottom frame 101, a driving pulley 307 is plugged and fixed in the rotating shaft of the driving motor 306, and a transmission belt 308 is sleeved and installed between the driving pulley 307 and the lapping pulley 305;

[0055] After the driving motor 306 is started, the driving pulley 307 can be driven to rotate, so that the driving pulley 307 drives the lapping pulley 305 to rotate through the transmission belt 308, thereby driving the lapping shaft 302 and the lapping teeth 303 to rotate at high speed;

[0056] In order to improve the stability and safety of the rotation of the lapping teeth 303 , a plurality of hollow cross-connecting columns 304 are evenly fixed between the plurality of lapping teeth 303 with the lapping shaft 302 as the center.

[0057] The specific structure of the primary grinding assembly 4 is as follows Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the bottom surface of the primary grinding solid cover 401 is arranged with primary grinding sieve holes 402, and each row of primary grinding sieve holes 402 and the solid grinding seat 403 are sequentially cross-distributed;

[0058] A side clamping seat 404 is also fixedly connected to one side of the inner top of the primary grinding cover 401, so that when the central gear 409 is in a free rotation state, under the elastic support of the reset slide bar 414 itself, when the top opening of the blanking funnel 406 is tilted toward the top side of the main shell 102, it can form an overlap with the side clamping seat 404, so that the corn starch slurry to be ground can be added to the blanking funnel 406 more safely;

[0059] The funnel swivel seat 405 is symmetrically fixedly installed on the outer side of the top of the main shell 102, and a funnel swivel shaft 407 is transversely fixed on the outer side of the blanking funnel 406. The two ends of the funnel swivel shaft 407 are respectively rotatably connected to the funnel swivel seat 405, and the blanking swing connecting rod 411 is fixedly connected to the outer side of one end of the funnel swivel shaft 407;

[0061] A first reset slide 412 and a second reset slide 413 are also fixed to the outer side of the main housing 102, and the first reset slide 412 and the second reset slide 413 are arranged in pairs, one end of the reset slide rod 414 is slidably connected to the first reset slide 412, and the other end is slidably connected to the second reset slide 413;

[0062] Furthermore, the first reset slide 412 will not interfere with the rotation of the electric cylinder connection seat 608 and its related mechanisms;

[0063] The clamping sleeve 415 is sleeved and fixed on the middle part of the outer side of the reset slide 414. The outer side of the reset slide 414 is also sleeved and installed with a compression spring 416. One end of the compression spring 416 is clamped on one side of the clamping sleeve 415, and the other end is clamped on one side of the second reset slide 413.

[0064] Under the action of the elastic force of the compression spring 416 on the ferrule 415, the reset slide rod 414 can have an elastic thrust in the direction of the first reset slide seat 412, so that the reset slide column 417 can form a sliding connection with the blanking swing link 411, driving the blanking swing link 411 to rotate to a position where the top opening of the blanking funnel 406 is naturally inclined toward the top side of the main shell 102;

[0065] The bottom surface of the material dropping funnel 406 is provided with material dropping holes 418, and the material dropping holes 418 and the dynamic grinding seat 419 are cross-distributed in sequence;

[0066] The cross section of the fixed grinding seat 403 is a trapezoidal structure with a small top and a large bottom, and the cross section of the dynamic grinding seat 419 is a trapezoidal structure with a large top and a small bottom. The sides of the fixed grinding seat 403 and the dynamic grinding seat 419 that grind against each other are both rough surfaces, which facilitates mutual grinding.

[0067] A material shaking assembly 5 is also provided at the position where the main housing 102 and the discharge hopper 103 meet, which can improve the fine grinding quality of the fine grinding teeth 303, so that the fine grinding teeth 303 can fully grind the corn starch slurry entering between the outer bottom surface of the primary grinding solid cover 401 and the inner bottom surface of the main housing 102; the specific structure of the material shaking assembly 5 is as follows: Fig. 9 and Fig.10 As shown, side seats 502 are fixed on both sides of the top of the shaking plate 501, and side rotating seats 503 are fixed on both sides of the inner cavity of the main shell 102, and the side rotating seats 503 are coaxial with the lapping rotating seat 301. The lapping shaft 302 passes through the side rotating seat 503 and forms a rotation connection with the lapping rotating seat 301, and the top of the side seat 502 is rotatably connected to the outside of the side rotating seat 503;

[0068] A material shaking swing arm 504 is fixed to one side of one set of side seats 502, a material shaking swing seat 505 is fixedly installed on an outer side surface of the main housing 102, a swing shaft 506 is rotatably connected in the material shaking swing seat 505, an externally connected large gear 507 is plugged and fixed to the outer end of the swing shaft 506, the center of the cam 509 is fixed to the inner end of the swing shaft 506, and a rotating small gear 508 is also fixed to one end of the lapping shaft 302, and the rotating small gear 508 is meshed with the externally connected large gear 507;

[0069] The inner side surface of the cam 509 is eccentrically fixed with a material shaking eccentric column 510, and the material shaking eccentric column 510 is slidably connected in the material shaking swing arm 504;

[0070] When the grinding shaft 302 rotates at a high speed, the rotation of the swing shaft 506 can be driven by the transmission cooperation formed by the rotating small gear 508 and the externally connected large gear 507, thereby driving the rotation of the cam 509, so that the shaking eccentric column 510 and the shaking swing arm 504 form an eccentric sliding cooperation, driving the side seat 502 and the shaking plate 501 to swing back and forth within a first range, and the sieve holes in the shaking plate 501 can be used to make the corn starch particles that meet its aperture size fall downward, and the corn starch particles that do not meet the aperture size of the sieve holes will continue to stay in the inner cavity of the main shell 102 in the vortex state formed by the high-speed rotation of the grinding teeth 303, until they are ground and crushed into a position that meets the aperture size of the sieve holes of the shaking plate 501, and the reciprocating swinging action of the shaking plate 501 itself will shake all the corn starch particles that have passed the grinding into the discharge hopper 103.

[0071] The specific structure of the safety transmission component 6 is as follows: Fig.11 and Fig.12 As shown, the outer support seat 601 is fixedly connected to the top of the bottom frame body 101, and the swing shaft 506 is rotatably connected in the outer support seat 601.

[0072] The outer end of the swing shaft 506 is also plugged and fixed with a rotating toothed belt wheel 602, one end of the outer side surface of the main housing 102 is fixed with a transmission shaft seat 603, a transmission shaft 604 is rotatably connected in the transmission shaft seat 603, a transmission gear 607 is plugged and fixed at the outer end of the transmission shaft 604, a transmission toothed belt wheel 605 is also fixed in the transmission shaft 604, and a toothed belt 606 is sleeved and installed between the transmission toothed belt wheel 605 and the rotating toothed belt wheel 602;

[0073] While the rotating small gear 508 and the externally connected large gear 507 form a coordinated transmission, the externally connected large gear 507 can also coaxially drive the rotating toothed belt wheel 602 to rotate through the swing shaft 506, the rotating toothed belt wheel 602 drives the transmission toothed belt wheel 605 to rotate through the toothed belt 606, and the transmission toothed belt wheel 605 drives the transmission gear 607 to rotate through the transmission shaft 604.

[0074] In addition, considering that the corn starch particles shaken off by the shaking plate 501 may form a pile inside the discharge hopper 103, the device also installs a pushing component 7 on the outer bottom surface of the shaking plate 501, and the pushing component 7 includes a pushing side seat 701 and a light rod 702. The pushing side seats 701 are fixedly connected to the outer bottom surface of the shaking plate 501 in pairs, and the light rod 702 is arranged and fixed between the two groups of pushing side seats 701. Through the reciprocating swinging action of the shaking plate 501, the pushing side seats 701 and the light rod 702 can form a reciprocating swinging action inside the discharge hopper 103, and the swinging range will not exceed the discharge hopper 103, thereby eliminating the problem of corn starch particles shaken off by the shaking plate 501 piling up inside the discharge hopper 103.
