Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and in particular to a pulverizing device for processing corn paste. Background Technology

[0002] Corn porridge, also known as cornmeal porridge, cornmeal soup, or corn stew, is rich in dietary fiber, protein, starch, fat, vitamins, and minerals. These nutrients play an important role in maintaining normal physiological functions, promoting metabolism, and enhancing immunity. It is a popular traditional whole grain food. In the production of corn porridge, efficient grinding of corn is an important processing step.

[0003] Existing crushing devices use a single crushing mechanism for crushing, resulting in excessive crushing intensity, rapid wear, and low crushing quality, which fails to adequately meet people's needs.

[0004] An existing patent (publication number: CN216063670U) discloses a pulverizing device with a sieving structure for processing corn paste. The device includes a frame assembly and pulverizing blades. The frame assembly, used for sound insulation, has a glass window and a frame cover arranged sequentially from top to bottom on its outer front end. The inner wall of the frame assembly is equipped with a motor, a motor, and a spring arranged sequentially from top to bottom. A gear set is located on one side of the motor, and a pulverizing wheel is mounted on the outside of the gear set. A motor cover is located at the front end of the motor, and a bearing is located on the outside of the motor. Compared to existing ordinary pulverizing devices, this pulverizing device with a sieving structure for processing corn paste uses a two-stage pulverizing process. The motor drives the pulverizing wheel to rotate via the gear set, and the two pulverizing wheels mesh to pulverize the product. The motor drives the shaft to rotate, causing the pulverizing blades to rotate and perform secondary pulverization of the product pulverized by the pulverizing wheels, thus improving the pulverizing effect. Because the pulverizing blades perform secondary pulverization, the intensity of use on the pulverizing blades is reduced, effectively slowing down wear.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1 to 5 This utility model provides a technical solution:

[0030] A pulverizing device for processing corn paste includes a frame 1 and a pulverizing box 2. The top and bottom of the pulverizing box 2 are respectively provided with a feed hopper 3 and a discharge hopper 4. Two sets of pulverizing motors 5 are bolted to the side wall of the pulverizing box 2. Two sets of first rotating shafts 6 are respectively fixedly connected to the output end of the pulverizing motors 5 in the middle of the pulverizing box 2. An active pulverizing roller 7 is provided on the side wall of the first rotating shaft 6. An adjustable pulverizing mechanism 8 is provided in the middle of the pulverizing box 2. A rotary screening mechanism 9 is provided at one end of the frame 1.

[0031] The adjustable crushing mechanism 8 includes a drive gear 801, a connecting plate 802, a connecting gear 803, an adjusting groove 804, an adjusting gear 805, a positioning rod 806, an adjusting block 807, a second rotating shaft 808, a driven crushing roller 809, and a driven gear 810. The drive gear 801 is fixedly connected to one end of the first rotating shaft 6. The connecting plate 802 is installed on the side wall of the crushing box 2. The connecting gear 803 is installed on the side wall of the connecting plate 802 and meshes with the drive gear 801. The adjusting groove 804 is formed in... On the side wall of the connecting plate 802, the adjusting gear 805 is installed inside the adjusting groove 804, two sets of positioning rods 806 are respectively bolted to the side wall of the crushing box 2, the adjusting block 807 is fixedly connected to one end of the positioning rod 806, the second rotating shaft 808 is installed in the middle of the two adjusting blocks 807, the driven crushing roller 809 is fixedly connected to the second rotating shaft 808, the driven gear 810 is fixedly connected to one end of the second rotating shaft 808, and the adjusting gear 805 meshes with the connecting gear 803 and the driven gear 810.

[0032] Specifically, such as Figure 2 As shown, the diameters of the two sets of active crushing rollers 7 and driven crushing rollers 809 are different, with the diameter of the active crushing roller 7 gradually decreasing from top to bottom.

[0033] Specifically, such as Figure 2 As shown, the inside of the crushing box 2 is equipped with two sets of guide plates 13, which are symmetrically and inclinedly arranged.

[0034] Specifically, such as Figure 3 As shown, a limit block 16 is installed on the side wall of the crushing box 2, and an adjusting block 807 is located between the limit block 16 and the connecting plate 802.

[0035] Raw materials enter the crushing chamber 2 through the feed hopper 3. Two sets of crushing motors 5 start, driving their respective first rotating shafts 6 and the active crushing rollers 7 on the side walls to rotate. Since the diameters of the two sets of active crushing rollers 7 gradually decrease from top to bottom, the raw materials experience progressively increasing crushing force as they flow downwards, thus achieving a double and uniform crushing effect on the corn. The active gear 801 rotates with the first rotating shaft 6 and meshes with the connecting gear 803 on the side wall of the connecting plate 802, thereby driving the connecting gear 803 to rotate. The connecting gear 803 then meshes with the adjusting gear 805 in the adjusting groove 804. The adjusting gear 805 simultaneously meshes with the driven gear 810, thereby driving the second rotating shaft 808 and the driven crushing roller 809 to rotate. Since the adjusting gear 805 is located in the adjustable adjusting groove 804, the adjusting block 807 is adjusted at the positioning rod 8... The position of the driven crushing roller 809 and the active crushing roller 7 are changed by adjusting the position of the adjusting gear 805 in the adjusting groove 804 to adapt to the needs of different crushing fineness. The crushed material flows evenly to the bottom of the crushing box 2 under the guidance of the guide plate 13. Finally, the material enters the rotary screening mechanism 9 at one end of the frame 1 through the discharge hopper 4 for further screening. The limiting block 16 installed on the side wall of the crushing box 2 works together with the adjusting block 807 to limit the movement range of the adjusting gear 805 in the adjusting groove 804, ensuring the stable operation of the entire adjustable crushing mechanism 8. In this way, the distance between the driven crushing roller 809 and the active crushing roller 7 can be flexibly adjusted, and the corn paste can be double-crushed according to the different standards of corn paste, and the corn flour particles of different diameters can be adjusted to be crushed.

[0036] Specifically, such as Figure 3 As shown, the rotary screening mechanism 9 includes support wheels 901, limiting rings 902, screening cylinder 903, drive motor 904, drive gear 905, gear ring 906, and drive chain 907. Multiple sets of support wheels 901 are installed on the side wall of the frame 1, and multiple sets of limiting rings 902 are respectively set on the side wall of two sets of support wheels 901. The screening cylinder 903 is fixedly connected to the inner wall of the limiting rings 902. The drive motor 904 is bolted to the bottom of the frame 1. The drive gear 905 is fixedly connected to the output end of the drive motor 904. The gear ring 906 is fixedly connected to the side wall of the screening cylinder 903. The drive chain 907 is installed on the gear ring 906 and the drive gear 905.

[0037] Specifically, such as Figure 4 As shown, a horizontal plate 10 is installed on the side wall of the frame 1, and an installation rod 11 is installed in the middle of the horizontal plate 10. Two sets of scrapers 12 are installed on the side wall of the installation rod 11, and the scrapers 12 are in contact with the inner wall of the screening cylinder 903.

[0038] Specifically, such as Figure 4As shown, a hopper 14 is installed at the bottom of the frame 1, and a vibrating motor 15 is bolted to the side wall of the hopper 14.

[0039] Specifically, such as Figure 4 As shown, a receiving hopper 17 is installed at one end of the frame 1, and the receiving hopper 17 is located below the screening cylinder 903.

[0040] After the drive motor 904 starts, the drive gear 905 fixed at its output end begins to rotate. Since the drive gear 905 is connected to the toothed ring 906 on the side wall of the screening cylinder 903 through the drive chain 907, the rotation of the drive gear 905 will drive the toothed ring 906 and the screening cylinder 903 to rotate together. The screening cylinder 903 is supported and limited by multiple sets of support wheels 901 to ensure its stability during rotation. The material that has been initially crushed falls from the crushing box 2 into the screening cylinder 903. As the screening cylinder 903 rotates, the material is subjected to centrifugal force and is thrown against the inner wall of the screening cylinder 903. Particles that meet the particle size requirements will fall into the receiving hopper 17 below through the screening cylinder 903, while particles that do not meet the particle size requirements will continue to remain in the screening cylinder 903 for further screening. To prevent material from getting stuck in the screening cylinder 903... To prevent material buildup or blockage of the screen holes, a mounting rod 11 is installed on the horizontal plate 10 on the side wall of the frame 1. The mounting rod 11 has two sets of scrapers 12, which are in close contact with the inner wall of the screening cylinder 903. As the screening cylinder 903 rotates, the scrapers 12 continuously scrape the inner wall of the screening cylinder 903, ensuring smooth material flow and effectively cleaning the screen holes. A vibrating motor 15 is bolted to the side wall of the feed hopper 14 at the bottom of the frame 1. The start of the vibrating motor 15 will cause the feed hopper 14 to vibrate, further promoting the flow of material in the feed hopper 14 and preventing material blockage or accumulation during the feeding process. The qualified material particles after screening fall into the receiving hopper 17 below through the screen holes of the screening cylinder 903. The setting of the receiving hopper 17 facilitates the collection and processing of the screened material. In this way, efficient screening processing of crushed corn is achieved, improving the accuracy of corn paste processing.

[0041] By adopting the above technical solution, the problem that existing corn paste processing crushing devices cannot adjust the spacing between the crushing rollers to crush corn flour particles of different sizes, and thus cannot meet the requirements for crushing different particles in corn paste, has been solved.

[0042] Working principle: In use, the two sets of crushing motors 5 start, driving their respective first rotating shafts 6 and the active crushing rollers 7 on the side walls to rotate. Since the diameters of the two sets of active crushing rollers 7 gradually decrease from top to bottom, the raw material experiences progressively stronger crushing force as it flows downwards, thus achieving a double crushing and uniform crushing effect on the corn. The active gear 801 rotates with the first rotating shaft 6 and meshes with the connecting gear 803 on the side wall of the connecting plate 802, thereby driving the connecting gear 803 to rotate. The connecting gear 803 then meshes with the adjusting gear 805 in the adjusting groove 804. The adjusting gear 805 simultaneously meshes with the driven gear 810, thereby driving the second rotating shaft 808 and the driven crushing roller 809 to rotate. Since the adjusting gear 805 is located in the adjustable adjusting groove 804, the adjusting block 807 is adjusted relative to the positioning rod 806. The relative position between the driven crushing roller 809 and the active crushing roller 7 is changed by adjusting the position of the adjusting gear 805 in the adjusting groove 804 to adapt to different crushing fineness requirements. After the drive motor 904 starts, the drive gear 905 starts to rotate. The rotation of the drive gear 905 drives the gear ring 906 and the screening cylinder 903 to rotate together. The material that has been initially crushed falls from the crushing box 2 into the screening cylinder 903. As the screening cylinder 903 rotates, the material is subjected to centrifugal force and is thrown against the inner wall of the screening cylinder 903. The material particles that meet the particle size requirements will fall into the receiving hopper 17 below through the screening cylinder 903. In this way, the dual crushing of corn paste raw materials is realized, and the distance between the driven crushing roller 809 and the active crushing roller 7 can be adjusted to meet the crushing requirements of different corn paste raw materials.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
