Description

Technical Field

[0001] The utility model relates to the technical field of miscellaneous grain flour mills, and specifically relates to a grain flour processor. Background Art

[0002] A miscellaneous grain flour mill is a machine that grinds various grains, Chinese herbal medicines and other foods into uniform powders with a mesh size of 50 - 200. The miscellaneous grain flour mill relies on two grinding disks covered with tooth grooves to rotate against each other to grind the materials into powders.

[0003] Two grinding disks are arranged in the miscellaneous grain flour mill. One grinding disk is fixedly connected to the equipment shell, and the other grinding disk is sleeved on the output shaft of the driving motor with a limit. When the miscellaneous grain flour mill is running, the position of the grinding disk sleeved on the output shaft of the driving motor can be adjusted to realize the adjustment of the gap distance between the two grinding disks, so as to achieve the adjustment of the particle size of the ground powder.

[0004] In actual operation, if you want to grind the materials to a finer state, you need to first grind the materials into smaller particles, and then further grind them finer. Repeating this process, the materials need to be ground multiple times to complete the full grinding of the materials. In order to simplify this operation, a grain flour processor is provided. Content of the Utility Model

[0005] The purpose of the utility model is to provide a grain flour processor to solve the problems in the above background.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A grain flour processor, including a flour mill composed of a machine case main body, a grinding chamber, a feeding hopper, and a chamber door. The grinding chamber is fixed to the front end of the machine case main body through a connecting pipe. The feeding hopper is fixed to the top of the connecting pipe of the grinding chamber. The chamber door is connected to one side of the grinding chamber through a rotating connecting piece. A fixed grinding disk is fixedly installed inside the grinding chamber. A rotating grinding component with a rotating grinding disk is also arranged inside the grinding chamber. The rotating grinding disk and the fixed grinding disk are symmetrically distributed. The grinding operation of the grains is realized by the relative rotation of the rotating grinding disk and the fixed grinding disk.

[0007] On the end faces of the fixed grinding disk and the rotating grinding disk close to each other, a plurality of annular grooves with gradually increasing diameters are formed. The plurality of annular grooves are distributed in sequence from the inside to the outside and the depths decrease in sequence. Grinding protrusions are formed on the end faces of the plurality of annular grooves.

[0008] The gap between the rotating grinding disk and the fixed grinding disk is limited to gradually decrease from the inside, so as to realize the step-by-step grinding of the grains.

[0009] As a further scheme of the utility model: The rotating grinding component further includes a rotating disk, a polygonal hole groove, and a spiral feeding cylinder column.

[0010] The rotating grinding disc is fixedly installed at one end of the outer wall of the rotating disc. The spiral feeding cylinder is fixed at one end of the rotating disc and passes through the center of the rotating grinding disc. The polygonal hole groove is opened at the center position of one end of the rotating disc, penetrates through the other end of the rotating disc, and is communicated with the inner cavity of the spiral feeding cylinder.

[0011] The output end of the driving motor inside the chassis main body is connected with a polygonal rotating shaft extending into the inner cavity of the grinding chamber. The rotating disc is sleeved outside the polygonal rotating shaft through the polygonal hole groove.

[0012] A compression spring is sleeved outside the polygonal rotating shaft. The compression springs are distributed in the inner cavity of the spiral feeding cylinder, and the two ends of the compression spring are respectively attached to the end face of the rotating disc and the outer wall protrusion of the polygonal rotating shaft.

[0014] As a further scheme of the present utility model: A spiral adjusting assembly extending to the inside of the grinding chamber is arranged outside the door of the chamber. The spiral adjusting assembly is attached to the end face of the rotating disc, and the spiral adjusting assembly is used to push the rotating disc to realize the adjustment of the distance between the rotating grinding disc and the fixed grinding disc.

[0015] As a further scheme of the present utility model: The annular grooves and grinding protrusions on the fixed grinding disc and the rotating grinding disc are integrally formed by a casting process and then finely processed by a numerical control lathe.

[0016] Compared with the prior art, the beneficial effects of the present utility model are:

[0017] By providing a fixed grinding disc and a rotating grinding disc provided with annular grooves, sufficient grinding of grains can be realized. Compared with the structure of a traditional flour mill that can only grind to a single specification of particle size at a time, through the structural setting of multiple annular grooves, multi-stage grinding of grains can be achieved in a single grinding.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 to 3 , in the embodiment of the present utility model, a grain flour processor includes a flour mill 1 composed of a main body of the chassis 101, a grinding chamber 102, a feeding hopper 103, and a bin door 104. The grinding chamber 102 is fixed to the front end of the main body of the chassis 101 through a connecting pipe. The feeding hopper 103 is fixed to the top of the connecting pipe of the grinding chamber 102. The bin door 104 is connected to one side of the grinding chamber 102 through a rotating connecting piece. A fixed grinding disc 2 is fixedly installed inside the grinding chamber 102. A rotating grinding assembly 5 with a rotating grinding disc 504 is also provided inside the grinding chamber 102. The rotating grinding disc 504 and the fixed grinding disc 2 are symmetrically distributed. The grinding operation of the grain is realized by the relative rotation of the rotating grinding disc 504 and the fixed grinding disc 2;

[0024] On the end faces of the fixed grinding disc 2 and the rotating grinding disc 504 close to each other, a plurality of annular grooves 6 with gradually increasing diameters are formed. The plurality of annular grooves 6 are sequentially distributed from the inside to the outside and the depths are sequentially decreasing. Grinding projections 7 are formed on the end faces of the plurality of annular grooves 6;

[0025] The gap between the rotating grinding disc 504 and the fixed grinding disc 2 is limited in sequence from the inside with decreasing self-limitation through a plurality of annular grooves 6, so as to realize the step-by-step grinding of the grain;

[0026] The rotating grinding assembly 5 further includes a rotating disc 501, a polygonal hole groove 502, and a spiral feeding cylinder column 503;

[0027] The rotating grinding disc 504 is installed and fixed at one end of the outer wall of the rotating disc 501. The spiral feeding cylinder column 503 is fixed at one end of the rotating disc 501 and passes through the center of the rotating grinding disc 504. The polygonal hole groove 502 is opened at the center position of one end of the rotating disc 501, penetrates through the other end of the rotating disc 501, and is communicated with the inner cavity of the spiral feeding cylinder column 503.

[0028] The output end of the drive motor inside the chassis main body 101 is connected with a polygonal rotating shaft 3 extending into the inner cavity of the grinding chamber 102. The rotating disc 501 is sleeved outside the polygonal rotating shaft 3 through the polygonal hole groove 502.

[0029] A compression spring 4 is sleeved outside the polygonal rotating shaft 3. The compression springs 4 are distributed in the inner cavity of the spiral feeding cylinder column 503, and the two end heads of the compression spring 4 are respectively in contact with the end face of the rotating disc 501 and the convex part of the outer wall of the polygonal rotating shaft 3. The compression spring 4 is used to provide an outward thrust for the rotating disc 501.

[0030] The rotating grinding assembly 5 further includes scraping blades 505. There are multiple scraping blades 505. The multiple scraping blades 505 are fixed at one end of the rotating disc 501 away from the spiral feeding cylinder column 503 and extend to the outside of the rotating disc 501. The outer diameter of the distribution track of the multiple scraping blades 505 matches the inner wall diameter of the grinding chamber 102.

[0031] In this embodiment: When grinding grains into powder, first start the drive motor inside the chassis main body 101. The drive motor drives the whole rotating grinding assembly 5 to rotate through the polygonal rotating shaft 3. Then pour the grains into the feeding hopper 103. The grains will fall along the feeding hopper 103 into the connecting pipe and be driven by the rotating spiral feeding cylinder column 503 to be conveyed into the grinding chamber 102.

[0032] At this time, the grains are located at the middle gap between the fixed grinding disc 2 and the rotating grinding disc 504. The grinding of the grains can be realized through the relative rotation of the rotating grinding disc 504 and the fixed grinding disc 2.

[0033] At the same time, due to the structural setting of the multiple annular grooves 6, the grains are ground step by step. That is, the grains located inside the inner annular groove 6 are ground into small granular shapes. The small granular grains fall into the middle of the second group of annular grooves 6 and are ground again into smaller grains. This process is repeated. Finally, the grains are ground into fine powder. Compared with the structure of the traditional flour mill that can only grind to one specification of particle size at a time, through the structural setting of the multiple annular grooves 6, multi-stage grinding of the grains can be realized in a single grinding. While ensuring smooth grinding, the grains can be ground to the required mesh number at one time, further improving the grinding efficiency.

[0034] Please refer to Figure 1, an external part of the bin door 104 is provided with a spiral adjusting assembly 8 extending to the inner side of the grinding bin 102. The spiral adjusting assembly 8 is in contact with the end face of the rotating disk 501. The spiral adjusting assembly 8 is used to push the rotating disk 501 to realize the adjustment of the distance between the rotating grinding disk 504 and the fixed grinding disk 2.

[0035] In this embodiment: the cooperation between the spiral adjusting assembly 8 and the compression spring 4 is used to realize the adjustment of the distance between the rotating grinding disk 504 and the fixed grinding disk 2, so as to realize the grinding operation of different mesh numbers of flour;

[0036] It should be supplemented and explained that: the spiral adjusting assembly 8 is a structure in existing equipment, and only the structure of the grinding disk is improved in this solution, and the structure improvement of the spiral adjusting assembly 8 is not involved. Therefore, the internal structure of the spiral adjusting assembly 8 is not elaborated.

[0037] Please refer specifically to Figures 1 to 3 , the annular grooves 6 and the grinding bumps 7 on the fixed grinding disk 2 and the rotating grinding disk 504 are integrally formed by a casting process, and then are finely processed and formed by a CNC lathe.

[0038] In this embodiment: this structure makes the overall processing technology of the fixed grinding disk 2 and the rotating grinding disk 504 simple, which is convenient for improvement and production on the basis of the original equipment, and is convenient for popularization and production.

[0039] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
