Description

Technical Field

[0001] This utility model relates to the field of stone mill flour processing technology, and in particular to a stone mill flour grading and sieving device. Background Technology

[0002] Stone-ground flour grading and sieving refers to the process of classifying the particle size of stone-ground flour using a stone-ground flour grading and sieving device. This process usually involves the coordinated operation of rotating parts in the device, which allows the flour to pass through sieves of different sizes in a dynamic environment, achieving the separation of coarse and fine particles, ensuring sieving efficiency, and ultimately classifying the flour into different grades according to particle size to meet the requirements of different food processing for the fineness of flour.

[0003] A search revealed Chinese patent CN222490993U, which discloses a stone-milled flour grading and sieving device. The device includes a sieving box with no cover on the top and right sidewalls. The front and rear inner walls of the sieving box have opposing horizontal slots, arranged in multiple sets evenly along the vertical direction. The right end of each slot extends out of the sieving box, and a sieve is inserted into the front of each opposing slot. A telescopic rod with a spring inside is located at the bottom of the sieving box. A vibration motor is mounted on the sidewall of the sieving box, and a removable baffle is provided on the right side. This invention facilitates material discharge and cleaning.

[0004] The above-mentioned technology uses a static sieve to sieve flour. Flour tends to accumulate on the sieve mesh, causing the sieve holes to become clogged and the sieving efficiency to drop significantly. Once clogged, the sieve mesh needs to be disassembled frequently for cleaning, which not only consumes a lot of manpower and time, but may also damage the sieve mesh or other parts of the device due to repeated disassembly, shortening the service life of the device. In addition, frequent disassembly and cleaning will interrupt the flour sieving process, affect the continuity of production, increase the cost of flour production and processing, and make it difficult to meet the needs of large-scale, high-efficiency modern production. Utility Model Content

[0005] The purpose of this invention is to provide a stone mill flour grading and sieving device that can solve the problems of the above-mentioned technology that uses static sieves to sieve flour, which easily causes flour to accumulate on the sieve mesh, resulting in sieve hole blockage and a significant reduction in sieving efficiency. Once blocked, the sieve mesh needs to be disassembled frequently for cleaning, which not only consumes a lot of manpower and time, but may also damage the sieve mesh or other parts of the device due to repeated disassembly, shortening the service life of the device. In addition, frequent disassembly and cleaning will also interrupt the flour sieving process, affect the continuity of production, increase the cost of flour production and processing, and make it difficult to meet the needs of large-scale, high-efficiency modern production.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a stone mill flour grading and sieving device, including a mounting base, and further comprising:

[0007] A driving component is disposed on one side of the mounting base;

[0008] A sieving bucket, located on the top outer side of the mounting base, is used to sift flour.

[0009] A feeding component is located on one side of the mounting base;

[0010] A receiving box is located on one side of the mounting base.

[0011] In a preferred embodiment, the driving component includes:

[0012] A connecting bracket is fixedly installed on the outer top of the mounting base;

[0013] The first bevel gear is rotatably mounted on the inner side of one end of the connecting frame;

[0014] A connecting shaft is fixedly mounted on one side of the first bevel gear;

[0015] The second bevel gear is rotatably mounted on the inner side of the other end of the connecting frame, and the outer side of one end of the second bevel gear is connected to one side of the screening barrel;

[0016] The third bevel gear is rotatably mounted on the inner side of the bottom end of the connecting frame, and the third bevel gear is connected to the first bevel gear and the second bevel gear respectively.

[0017] In a preferred embodiment, a motor is mounted on the outer top of the mounting base, and the outer side of the motor's main shaft is connected to one side of the first bevel gear.

[0018] In a preferred embodiment, a connecting plate is fixedly provided on the outer side of one end of the connecting shaft, and a plurality of scrapers are fixedly provided on the outer side of the connecting plate, the scrapers being in contact with the outer surface of the screening barrel.

[0019] In a preferred embodiment, a plurality of cleaning plates are fixedly provided on the outer side of the connecting shaft, and a cleaning head is provided on the outer side of the end of the cleaning plate, the cleaning head being in contact with the inner wall surface of the screening barrel.

[0020] In a preferred embodiment, the feeding component includes:

[0021] The first pulley is rotatably mounted on one side of the receiving box;

[0022] The second pulley is rotatably mounted on one side of the receiving box, and the first pulley and the second pulley are connected by a belt;

[0023] The spiral fan blades are fixedly mounted on one side of the first pulley.

[0024] In a preferred embodiment, the bottom outer side of the receiving box is provided with sieve holes.

[0025] In a preferred embodiment, a partition is fixedly provided on the inner side of the mounting base, the partition being used to separate the flour.

[0026] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0027] In operation, this utility model, when the stone mill flour grading and sieving device starts its motor, drives the first bevel gear to rotate, which in turn drives the second bevel gear to rotate via the third bevel gear. This relative rotation of the first and second bevel gears, in turn, causes the connecting plate at the end of the rotating shaft and the sieving barrel to rotate relative to each other. This allows the flour inside the sieving barrel to continuously roll and be sieved. Simultaneously, a scraper on the outside of the connecting plate scrapes the outside of the sieving barrel to prevent flour accumulation. A cleaning plate and cleaning head fixed to the outside of the rotating shaft scrape away flour from the inner wall of the sieving barrel to prevent clogging. The grooved surface of the cleaning plate allows it to deform, preventing damage to the inner wall of the sieving barrel. The advantages are that the relative rotation of the connecting plate and the sieving barrel enables continuous rolling and sieving of the flour, significantly improving sieving efficiency and ensuring flour grading accuracy. Simultaneously, the continuous scraping of the inner and outer walls of the sieving barrel by the scraper, cleaning plate, and cleaning head effectively removes accumulated flour, preventing internal and external blockages. The deformable design of the cleaning plate also protects the screen during cleaning. Through the coordinated operation of sieving and cleaning, this device ensures both sieving efficiency and unobstructed operation, improving the continuity of stone mill flour processing and the quality of the finished product.

Detailed Implementation

[0034] 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.

[0035] Example 1:

[0036] Please see Figures 1-4 This embodiment provides a stone mill flour grading and sieving device that prevents clogging and is easy to clean. The specific idea is as follows:

[0037] The stone mill flour grading and sieving device includes a mounting base 1. In addition, the stone mill flour grading and sieving device also includes a sieving barrel 2 disposed on the outer side of the top of the mounting base 1. The sieving barrel 2 is used to sieve the flour. Through the continuous rotation of the sieving barrel 2, the flour can fall naturally under the action of gravity, preventing the sieving barrel 2 from clogging.

[0038] In order to achieve the rotation function of the screening barrel 2, this embodiment provides a driving component that can drive the screening barrel 2 to rotate, while continuously cleaning the inner wall and outer side of the screening barrel 2, further preventing the screening barrel 2 from clogging.

[0039] The driving component in this embodiment includes: a connecting frame 202 fixedly connected to the outer top of the mounting base 1; a first bevel gear 203 rotatably connected to the inner side of one end of the connecting frame 202; a connecting shaft 204 fixedly connected to one side of the first bevel gear 203; a second bevel gear 205 rotatably connected to the inner side of the other end of the connecting frame 202; the outer side of the connecting shaft 204 rotatably connected to the inner side of the second bevel gear 205; the outer side of one end of the second bevel gear 205 fixedly connected to one side of the screening barrel 2; and a third bevel gear 206 rotatably connected to the inner bottom of the connecting frame 202. The third bevel gear 206 meshes with the first bevel gear 203 and the second bevel gear 205 respectively, and is used to drive the first bevel gear 203. The wheel 203 and the second bevel gear 205 rotate relative to each other. A motor 201 is installed on the outer side of the top of the mounting base 1. The outer side of the main shaft of the motor 201 is fixedly connected to one side of the first bevel gear 203 to drive the first bevel gear 203 to rotate. A connecting plate 207 is fixedly connected to the outer side of one end of the connecting shaft 204. Multiple scrapers 210 that contact the outer surface of the screening barrel 2 are fixedly connected to the outer side of the connecting plate 207 to scrape and clean the outer side of the screening barrel 2. Multiple cleaning plates 208 are fixedly connected to the outer side of the connecting shaft 204. A cleaning head 209 that contacts the inner wall surface of the screening barrel 2 is connected to the outer side of the end of the cleaning plate 208 to clean the inner wall surface of the screening barrel 2.

[0040] In the specific implementation process: When using the device, the user can start the motor 201. The motor 201 drives the first bevel gear 203 to rotate. At the same time, the rotation of the first bevel gear 203 will drive the second bevel gear 205 to rotate through the third bevel gear 206. This causes the first bevel gear 203 and the second bevel gear 205 to rotate relative to each other, which in turn drives the connecting plate 207 at the end of the connecting shaft 204 and the sieving barrel 2 to rotate relative to each other. At this time, the flour inside the sieving barrel 2 is continuously sifted. Meanwhile, the scraper 210 on the outside of the connecting plate 207 can continuously scrape the outside of the sieving barrel 2 to prevent the flour from accumulating on the outside of the sieving barrel 2. At the same time, the cleaning plate 208 and the cleaning head 209 fixed on the outside of the connecting shaft 204 can continuously scrape the inner wall of the sieving barrel 2 to prevent the flour from accumulating and clogging inside the sieving barrel 2. At the same time, the through groove on the surface of the cleaning plate 208 can deform the cleaning plate 208 to a certain extent to prevent damage to the inner wall of the sieving barrel 2.

[0041] Example 2:

[0042] Please see Figures 1-4 This embodiment provides a stone mill flour grading and sieving device that facilitates the collection of sieved flour. The specific concept is as follows:

[0043] The stone mill flour grading and sieving device includes a mounting base 1. In addition, the stone mill flour grading and sieving device also includes a sieving bucket 2 set on the outer side of the top of the mounting base 1. The sieving bucket 2 is used to sieve the flour. Through the continuous rotation of the sieving bucket 2, the flour can fall naturally under the action of gravity, preventing the sieving bucket 2 from clogging. A receiving box 3 is fixedly connected to one side of the mounting base 1 for collecting the sieved flour.

[0044] In order to realize the collection function of receiving box 3, this embodiment provides a feeding component that can drive receiving box 3 to convey the sieved flour, and at the same time, can further sieve the flour.

[0045] The feeding component in this embodiment includes: a first pulley 301 rotatably connected to one side of the receiving box 3, and a second pulley 302 rotatably connected to one side of the receiving box 3. The first pulley 301 and the second pulley 302 are connected by a belt. At the same time, the second pulley 302 is fixedly connected to the connection between the second bevel gear 205 and the sieving barrel 2. The second bevel gear 205 can drive the second pulley 302 to rotate. A spiral fan blade 303 is fixedly connected to one side of the first pulley 301. The spiral fan blade 303 is placed inside the bottom end of the receiving box 3. The first pulley 301 can drive the spiral fan blade 303 to rotate. A sieve hole 305 is opened on the outer side of the bottom end of the receiving box 3 for further sieving of the flour. A partition 304 for separating the flour is fixedly connected to the inner side of the mounting base 1.

[0046] In the specific implementation process: when the second bevel gear 205 rotates, it will drive the first pulley 301 to rotate through the second pulley 302 and the belt. At the same time, the rotation of the first pulley 301 will drive the spiral fan blade 303 on the inner side of the bottom of the receiving box 3 to rotate. The flour sieved by the screening barrel 2 will enter the interior of the receiving box 3 and be conveyed by the spiral fan blade 303. At the same time as conveying, some flour will be sieved by the second bevel gear 205. Large particles of flour that are not sieved will flow into the other side of the partition 304 to facilitate the sieving of flour.

[0047] Working principle:

[0048] Based on Example 1, after the stone mill flour grading and sieving device starts the motor 201, the motor 201 drives the first bevel gear 203 to rotate, and drives the second bevel gear 205 to rotate through the third bevel gear 206, so that the first bevel gear 203 and the second bevel gear 205 rotate relative to each other, thereby driving the connecting plate 207 at the end of the connecting shaft 204 and the sieving barrel 2 to rotate relative to each other, so that the flour on the inner side of the sieving barrel 2 continues to roll and sieve. At the same time, the scraper 210 on the outside of the connecting plate 207 scrapes the outside of the sieving barrel 2 to prevent flour from accumulating. The cleaning plate 208 and the cleaning head 209 fixed on the outside of the connecting shaft 204 scrape the flour on the inner wall of the sieving barrel 2 to avoid blockage, and the groove on the surface of the cleaning plate 208 deforms it to prevent damage to the inner wall of the sieving barrel 2. Its advantages are that the relative rotation between the connecting plate 207 and the screening barrel 2 enables continuous sieving of flour, which greatly improves the sieving efficiency and ensures the accuracy of flour grading. At the same time, the scraper 210, cleaning plate 208 and cleaning head 209 continuously scrape the inner and outer walls of the screening barrel 2, effectively removing accumulated flour and avoiding internal and external blockage. The deformation design of the cleaning plate 208 can also protect the screen during cleaning. Through the coordinated operation of sieving and cleaning, this device ensures both sieving efficiency and smooth operation of the device, improving the continuity of stone mill flour processing and the quality of finished products.

[0049] Based on Example 2, in this stone mill flour grading and sieving device, when the second bevel gear 205 rotates, it drives the first pulley 301 to rotate via the second pulley 302 and the belt. The first pulley 301 further drives the spiral fan blade 303 on the inner side of the bottom of the receiving box 3 to rotate. The flour sieved by the screening barrel 2 enters the receiving box 3 and is conveyed by the spiral fan blade 303. During the conveying process, some flour is screened a second time by the second bevel gear 205, and the large particles of flour that are not screened flow to the other side of the partition 304. The advantage of this design is that by linking the conveying of the spiral fan blade 303 with the secondary screening of the second bevel gear 205, the flour can be graded and screened multiple times during the conveying process, effectively improving the flour screening efficiency and accuracy. At the same time, the design of automatically flowing large particles of flour to the other side of the partition 304 facilitates the classification and collection of flour of different particle sizes, ensuring the continuity and efficiency of flour grading and sieving, and meeting the processing needs of different flour products.

[0050] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
