Description

Technical Field

[0001] The invention belongs to the technical field of grinding devices and discloses a grinding device for food processing. Background Art

[0002] In the process of producing flour, a grinder is needed to grind wheat into flour. However, in the process of grinding wheat, when the wheat grains are poured into the grinder and the millstone rotates to grind the wheat grains into flour of uniform size and coarseness, the wheat grains are poured into the grinder together, and the sizes of the wheat grains entering the grinder are not the same. Therefore, when the grinder grinds the wheat grains, if the large wheat grains and the small wheat grains are ground at the same time, then when the small wheat grains are ground to the standard, the large wheat grains have not been ground to the standard, which will cause the qualified finished products to be over-grinded. At the same time, since the grinding time required for large wheat grains is longer than that for small wheat grains, the large wheat grains occupy the millstone for a longer time, and since the large wheat grains have been occupying the millstone, the overall grinding time increases, affecting the grinding efficiency of the grinder.

[0031] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0032] Embodiment 1: A grinding device for food processing, such as Figure 1-Figure 5As shown, it includes a support frame 1, a control terminal (not shown in the figure) is arranged on the support frame, a fixed shell 11 is fixedly connected to the left portion of the upper side of the support frame 1, a feed port is arranged at the upper portion of the left side of the fixed shell 11, a discharge port is arranged at the lower portion of the left side of the fixed shell 11, a feed hopper 12 is fixedly connected and communicated with the feed port of the fixed shell 11, a grinding disc 13 is rotatably connected in the fixed shell 11, a first motor 14 electrically connected to the control terminal is installed in the left portion of the lower side of the support frame 1, an output shaft of the first motor 14 is fixedly connected to the grinding disc 13, and the fixed shell 11 is fixedly connected to the grinding disc 13. A material distribution frame 15 is fixedly connected between the grinding disc 13 and the feed port, and discharge ports are arranged on the left and rear sides of the material distribution frame 15. A filter frame 16 is rotatably connected to the upper side of the material distribution frame 15. The aperture of the left filter hole on the filter frame 16 is smaller than the aperture of the right filter hole. The left discharge port on the material distribution frame 15 is located at the lower side of the left filter hole on the filter frame 16, and the rear discharge port on the material distribution frame 15 is located at the lower side of the right filter hole on the filter frame 16. The filter frame 16 is connected to the feed hopper 12. The lower side of the material distribution frame 15 is fixedly connected to a distribution port fixed to the fixed shell 11. The material rack 17 divides the area in which it is located in the fixed shell 11 into three parts, and each part is provided with an arc-shaped fixed block 18 in contact with the inner wall of the fixed shell 11. The inner diameter of the rear arc-shaped fixed block 18 is located between the left front side and the right front side. The distance between the lower side of the three arc-shaped fixed blocks 18 and the outer side of the grinding disc 13 is consistent. The area where the left front arc-shaped fixed block 18 is located on the material rack 17 is connected to the discharge port on the left side of the material rack 15. The area where the rear arc-shaped fixed block 18 is located on the material rack 17 is connected to the discharge port on the left side of the material rack 15. The discharge port on the rear side is connected, and the area where the right front arc-shaped fixed block 18 is located on the dividing frame 17 is connected to the right side of the filter frame 16. The three arc-shaped fixed blocks 18 are all used in conjunction with the grinding disc 13 to grind the raw materials. The lower side of the grinding disc 13 is flush with the lower side of the discharge port of the fixed shell 11. The grinding disc 13 is fixedly connected with a discharge plate 19, and the material plate 19 is flush with the discharge port on the fixed shell 11, thereby pushing the ground raw materials to be discharged through the discharge port on the fixed shell 11. The fixed shell 11 is provided with an anti-blocking cleaning mechanism for preventing the filter frame 16 from being blocked.

[0033] like Figure 6 and Figure 7As shown, the anti-blocking cleaning mechanism includes a second motor 2, which is installed on the upper part of the right side of the fixed shell 11, and the output shaft of the second motor 2 is fixedly connected to a fixed shaft 21, which passes through the fixed shell 11 and is rotatably connected thereto, and a first rotating wheel 22 is fixedly connected to the left side of the fixed shaft 21, and a second rotating wheel 23 that is frictionally driven with the first rotating wheel 22 is fixedly connected to the right side of the filter frame 16, and the fixed shell 11 is rotatably connected to a spiral leaf 24 located in the filter frame 16, and the outer diameter of the spiral leaf 24 is consistent with the inner diameter of the filter frame 16, so that the wheat grains pass through evenly and at a uniform speed, and the spiral leaf 24 and the fixed shaft 21 are connected to each other. The drive is transmitted by a pulley and a belt. Two fixed disks 25 symmetrically distributed on the left and right are fixedly connected to the upper side of the fixed shell 11. The lower sides of the two fixed disks 25 are slidably connected with clearing blocks 26. A plurality of isosceles trapezoidal blocks are arranged on the lower side of the clearing blocks 26. The waists of the isosceles trapezoidal blocks are respectively located on the front and rear sides, and the cross-sectional area of ​​the filter holes on the filter frame 16 is larger than the cross-sectional area of ​​the lower side of the adjacent isosceles trapezoidal blocks, but smaller than the cross-sectional area of ​​the upper side of the adjacent isosceles trapezoidal blocks. The isosceles trapezoidal blocks are used to clean the blockages in the filter holes. An anti-blocking cleaning component for moving the symmetrically distributed clearing blocks 26 is arranged on the fixed shaft 21.

[0034] like Figure 7 As shown, the anti-blocking cleaning component includes two cams 3 symmetrically distributed on the left and right, the two cams 3 symmetrically distributed on the left and right are fixed to the left side of the fixed shaft 21, the two cams 3 symmetrically distributed on the left and right are respectively rotatably connected in adjacent fixed disks 25, the fixed disk 25 is rotatably connected to the fixed shaft 21, the clearing block 26 is fixedly connected to a pressure block 31 located in the adjacent fixed disk 25, the upper end of the pressure block 31 is set to an arc shape, when the arc at the upper end of the pressure block 31 is squeezed by the protrusion of the adjacent cam 3, the pressure block 31 moves downward, and a spring 32 is connected between the pressure block 31 and the adjacent fixed disk 25.

[0035] When the grinder grinds wheat grains, due to the different sizes of wheat grains, large wheat grains and small wheat grains will be ground at the same time. When the small wheat grains are ground to the standard, the large wheat grains have not yet been ground to the standard. This may not only cause the qualified finished products to be over-grinded, but also increase the overall grinding time. Therefore, when the device needs to grind raw materials, the staff starts the first motor 14 through the control terminal, and the output shaft of the first motor 14 drives the grinding disc 13 to rotate. The staff puts the raw materials into the feed hopper 12, and then the wheat grains in the feed hopper 12 enter the filter frame 16. After entering the filter frame 16, the raw materials are first filtered by the filter holes on the left side thereof. At this time, a batch of raw materials with the smallest diameter in the filter frame 16 moves downward through the filter holes on the left side thereof, and passes through the discharge port on the left side of the dividing frame 15 and enters between the arc-shaped fixed block 18 on the left front side and the grinding disc 13. At this time, the rotating grinding disc 13 cooperates with the arc-shaped fixed block 18 on the left front side to grind the raw materials entering therebetween.

[0036] In the process of the wheat grains in the feed hopper 12 entering the filter frame 16, the wheat grains that have not been filtered by the filter holes on the left side of the filter frame 16 continue to move. When these wheat grains move to the filter holes on the right side of the filter frame 16, the wheat grains with a middle diameter move downward through the filter holes on the right side of the filter frame 16, and pass through the discharge port on the rear side of the dividing frame 15 and enter between the rear arc-shaped fixed block 18 and the grinding disc 13, and then repeat the above process to be ground. In this process, the wheat grains that have not been filtered, after passing through the filter frame 16, move downward into between the right front arc-shaped fixed block 18 and the grinding disc 13, and then repeat the above process to grind the wheat grains.

[0037] The different sizes of wheat grains are filtered by utilizing the different apertures of the filter holes on the filter frame 16, and the wheat grains of different sizes are transported to between the corresponding arc-shaped fixed block 18 and the grinding disc 13, so as to accurately grind the raw materials of fixed sizes, thereby avoiding the situation in which the overall grinding time increases due to the long grinding time required for grinding large wheat grains, thereby affecting the grinding efficiency.

[0038] When the staff puts the raw materials into the feed hopper 12, the staff starts the second motor 2 through the control terminal. The output shaft of the second motor 2 drives the fixed shaft 21 to rotate. The fixed shaft 21 rotates through the pulley and belt drive spiral blades 24. The spiral blades 24 cooperate with the filter frame 16 to make the wheat grains pass evenly and at a uniform speed, ensuring that the wheat grains are fully filtered.

[0039] During the rotation of the fixed shaft 21, the fixed shaft 21 drives the first rotating wheel 22 to rotate, and the first rotating wheel 22 drives the filter frame 16 to rotate through the friction transmission of the second rotating wheel 23, so that the wheat grains blocked in the filter holes on the filter frame 16 are scraped off by the clearing block 26, so as to avoid the filter holes on the filter frame 16 being blocked, which affects the efficiency of the filter frame 16 in screening wheat grains.

[0040] During the rotation of the fixed shaft 21, the fixed shaft 21 drives the cam 3 to rotate and squeeze the adjacent pressure block 31. After being squeezed, the pressure block 31 drives the clearing block 26 to move downward and compress the adjacent spring 32. The clearing block 26 moves downward to squeeze the wheat grains blocked in the filter holes on the filter frame 16, and clears the filter holes on the filter frame 16. In this way, the filter holes on the filter frame 16 are protected to avoid the blocked wheat grains squeezing the filter holes when the clearing block 26 scrapes off the blocked wheat grains in the filter holes, causing damage to the filter holes.

[0041] In the above process, the ground wheat grains fall between the fixed shell 11 and the grinding disc 13, and then the wheat grains are discharged through the discharge port on the fixed shell 11. During this process, the grinding disc 13 drives the discharge plate 19 to rotate and push the ground wheat grains, thereby accelerating the discharge speed of the wheat grains between the fixed shell 11 and the grinding disc 13.

[0042] After all the wheat grains are ground and discharged from the fixed shell 11, the staff turns off the first motor 14 and the second motor 2 through the control terminal.

[0043] In this embodiment, the connection relationship between the fixed shell 11 and the material distribution rack 17 and the arc-shaped fixed block 18 is a fixed connection, but this is only used to limit this embodiment. In other embodiments, the connection relationship between the fixed shell 11 and the material distribution rack 17 and the arc-shaped fixed block 18 can be a sliding connection. The specific connection relationship can be seen from the specific description in the embodiment.

[0044] Embodiment 2: Based on embodiment 1, Figure 8-Figure 11 As shown, it also includes a cooling mechanism, which is arranged on the support frame 1, and is used to reduce the temperature of the grinding location. The cooling mechanism includes a cooling box 4, and a cooling device is arranged in the cooling box 4. The cooling box 4 is installed on the upper side of the support frame 1, and a reflux box 41 is installed on the upper side of the support frame 1. The reflux box 41 and the cooling box 4 are connected through a delivery pump. Three groups of evenly distributed cooling pipes 42 are fixedly connected to the outer side of the fixed shell 11, and the three groups of evenly distributed cooling pipes 42 are respectively located on the outer sides of adjacent arc-shaped fixed blocks 18. The distance between the uppermost side and the lowermost side of each group of evenly distributed cooling pipes 42 is consistent with the height of the adjacent arc-shaped fixed blocks 18. Each group of evenly distributed cooling pipes 42 and the cooling box 4 are connected with a liquid inlet pipe 43, and each group of evenly distributed cooling pipes 42 and the reflux box 41 are connected with a liquid return pipe 44. A cooling and cooling regulating component for adjusting the amount of coolant delivered to each group of evenly distributed cooling pipes 42 is provided on the support frame 1.

[0045] like Figure 8-Figure 11 As shown, the cooling and temperature adjustment component includes three first pneumatic telescopic parts 5, and the three first pneumatic telescopic parts 5 are fixedly connected to the upper side of the support frame 1. Three temperature sensing blocks 51 are fixedly connected to the upper side of the grinding disc 13. The three temperature sensing blocks 51 are respectively located at the lower sides of adjacent arc-shaped fixed blocks 18. The telescopic ends of the first pneumatic telescopic parts 5 are sealed and slidably matched with the adjacent temperature sensing blocks 51. A cavity is provided in the temperature sensing block 51. The cavity of the temperature sensing block 51 is divided into two parts by the telescopic ends of the adjacent first pneumatic telescopic parts 5, and the upper side The part is filled with temperature-sensitive gas whose volume changes with temperature. Three second pneumatic telescopic parts 52 are fixedly connected to the upper side of the support frame 1. The fixed parts of the three second pneumatic telescopic parts 52 are connected to the fixed parts of the adjacent first pneumatic telescopic parts 5 via connecting pipes 53. The liquid inlet pipe 43 is fixedly connected and connected to a square shell 54. The telescopic end of the second pneumatic telescopic part 52 is fixedly connected to a blocking block 55. The blocking block 55 is sealingly and slidably connected to the adjacent square shell 54, thereby regulating the flow area of ​​the coolant in the adjacent square shell 54.

[0046] When the staff starts the second motor 2 through the control terminal, the cooling box 4 and the delivery pump are started through the control terminal at the same time. The cooling box 4 cools the coolant therein, and the delivery pump delivers the cooled coolant into three groups of evenly distributed cooling pipes 42 through three liquid inlet pipes 43. Each group of evenly distributed cooling pipes 42 cools the wheat grains ground between the grinding disc 13 and the adjacent arc-shaped fixed block 18.

[0047] In the above process, since the sizes of the wheat grains ground by the three arc-shaped fixed blocks 18 are different, the temperatures of the wheat grains at the three arc-shaped fixed blocks 18 are also different. Therefore, the temperatures of the wheat grains at the three arc-shaped fixed blocks 18 are detected by the temperature-sensitive gases in the three temperature-sensitive blocks 51. When the temperature-sensitive gases in the temperature-sensitive blocks 51 detect that the temperature of the wheat grains at the corresponding arc-shaped fixed blocks 18 has increased, the temperature-sensitive gases in the temperature-sensitive blocks 51 expand and squeeze the telescopic ends of the adjacent first pneumatic telescopic parts 5 to move downward. Subsequently, the gas in the fixed part of the first pneumatic telescopic part 5 enters the fixed part of the adjacent second pneumatic telescopic part 52 through the adjacent connecting pipe 53, so that the telescopic end of the second pneumatic telescopic part 52 drives the adjacent blocking block 55 to move upward, thereby increasing the flow area of ​​the coolant in the square shell 54, thereby accelerating the circulation efficiency of the coolant and accurately cooling the wheat grains at different arc-shaped fixed blocks 18.

[0048] Embodiment 3: Based on embodiment 2, Figure 8 and Fig.12 As shown, it also includes a particle size adjustment mechanism, which is arranged on the fixed shell 11. The particle size adjustment mechanism is used to adjust the size of the wheat grains after grinding. The particle size adjustment mechanism includes a connecting rod 6, and the connecting rod 6 is fixed to the arc-shaped fixed block 18 on the left front side. Two adjacent arc-shaped fixed blocks 18 among the three arc-shaped fixed blocks 18 are fixed to each other through connecting blocks, and the connecting blocks between two adjacent arc-shaped fixed blocks 18 slide on the distribution rack 17. The fixed shell 11 and the distribution rack 17 are both slidably connected to the arc-shaped fixed blocks 18, and the connecting rod 6 is threadedly connected to a threaded rod 61 rotatably connected to the fixed shell 11.

[0049] When it is necessary to adjust the size of the ground wheat grains, the staff rotates the threaded rod 61, and the threaded rod 61 rotates the transmission connecting rod 6 to drive the arc-shaped fixed block 18 on the left front side to move, thereby transmitting the other arc-shaped fixed blocks 18 to move synchronously, thereby adjusting the distance between the arc-shaped fixed block 18 and the grinding disc 13, and thus adjusting the size of the ground wheat grains, thereby improving the applicability of the device.

[0050] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
