Description

Technical Field

[0001] This utility model relates to the field of whole wheat flour production, processing and grinding, and in particular to a fine grinding device for whole wheat flour. Background Technology

[0002] As is well known, in the whole wheat flour production and processing process, grinding and screening are the core processes that determine the particle size accuracy and quality of the finished product. In order to achieve fine processing of whole wheat flour, the industry generally adopts a combination of "grinding + sieve filtration". The sieve blocks the substandard coarse particles and returns them to the grinding device for further grinding, thereby improving the fineness and uniformity of the whole wheat flour.

[0003] Currently, in related technologies, a search reveals that a utility model with patent publication number CN217093712U discloses a fine grinding device for whole wheat flour production and processing. This device uses a base plate to support a fixed block, thereby connecting a large grinding jar and a small grinding jar to form a double-layer grinding structure. Furthermore, screens are installed on the inner walls of the discharge ports on the four sides of the lower surface of the large and small grinding jars, realizing the simultaneous grinding and screening, and solving the problem of insufficient precision in traditional single-stage grinding.

[0004] Regarding the aforementioned technologies, the inventors of this utility model have discovered that in actual production, bran and fine powder in whole wheat raw materials easily adhere to the mesh of the screen. After long-term operation, this can easily cause screen blockage, which not only slows down the discharge speed but may even cause raw materials to accumulate and stagnate in the grinding tank, forcing the production line to stop for cleaning. However, cleaning the blocked screen requires manual disassembly of the entire discharge port structure, which is cumbersome and time-consuming, increasing the labor intensity of operators and making it impractical.

[0005] Therefore, it is necessary to propose a fine grinding device for whole wheat flour. Utility Model Content

[0006] The purpose of this invention is to provide a fine grinding device for whole wheat flour to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0011] The feed pipe is disposed on the second grinding disc, and one end of the feed pipe is connected to the inner cavity of the second grinding disc;

[0012] The unloading bin is located at one end of the grinding device body through a unloading hole, and a strip-shaped hole is opened at the bottom of the unloading bin, and a filter screen is installed inside the strip-shaped hole;

[0013] The hopper cover is hinged to the unloading hopper via two hinges, and a limit assembly is provided between the hopper cover and the unloading hopper;

[0014] A support assembly disposed within a base for supporting the base in its place of use.

[0015] As a further improvement of this utility model: the limiting component includes a safety lock and a safety buckle, both of which are symmetrically arranged on the unloading hopper and the hopper cover, and the safety lock and the safety buckle are compatible with each other.

[0016] As a further improvement of this utility model: a strip handle is fixedly connected to the cover, and an anti-slip rubber sleeve is provided on the outside of the strip handle.

[0017] As a further embodiment of this utility model: the support assembly includes multiple support columns, each of which is fixedly connected to the base through a mounting groove, and the other end of each support column is fixedly connected to a support seat.

[0018] As a further improvement of this utility model, the bottom of each of the multiple support seats is provided with an anti-slip rubber pad.

[0019] As a further improvement of this utility model, a feed hopper is connected to the feed pipe.

[0027] 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.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Please see Figures 1-4 In this embodiment of the invention, a whole wheat flour fine grinding device includes:

[0030] Base 1;

[0031] The grinding device body 2 is fixedly installed on the base 1, and a grinding disc 3 is provided on the grinding device body 2, and a grinding disc 4 is provided inside the grinding disc 3.

[0032] Feed pipe 5 is provided on grinding disc 2 4, and one end of feed pipe 5 is connected to the inner cavity of grinding disc 2 4.

[0033] The unloading bin 6 is located at one end of the grinding device body 2 through the unloading hole, and the bottom of the unloading bin 6 is provided with a strip hole, and a filter screen 7 is provided in the strip hole;

[0034] The bin cover 8 is hinged to the unloading bin 6 via two hinges 9, and a limit assembly is provided between the bin cover 8 and the unloading bin 6;

[0035] A support assembly is disposed within the base 1 and is used to support the base 1 in the position of use.

[0036] In this whole wheat flour fine grinding device, multiple support columns 14 are securely connected to the base 1 via mounting slots. The anti-slip rubber pads 16 at the bottom of the support base 15 are undamaged and free of debris, ensuring that the device does not slip or tilt when placed at the production station, providing a stable foundation for subsequent grinding operations. Simultaneously, the safety locks 10 and 11 confirm that the hopper cover 8 is tightly closed. Then, the feeding and grinding operations are performed. The whole wheat raw material to be ground is poured into the feed hopper 17 connected to the feed pipe 5. The raw material smoothly enters the inner cavity of the second grinding disc 4 through the feed pipe 5. The main body 2 of the grinding device is started, and the first grinding disc 3 and the second grinding disc 4 cooperate to perform double-layer fine grinding of the raw material. The ground powder... The material enters the discharge bin 6 through the discharge hole and is filtered by the bottom filter screen 7 under gravity. Fine powder that meets the standards passes through the filter screen and is discharged, while coarse particles that do not meet the standards remain in the bin for subsequent re-grinding. When the discharge speed slows down or the filter screen shows signs of clogging, the operator can pause the device, unlock the symmetrically set safety locks 10 and safety buckles 11, and lift the bin cover 8 upwards through the hinge 9. Without disassembling the entire discharge bin 6 or the discharge port structure, the filter screen 7 can be directly removed from the strip hole. The bran, fine powder impurities attached to the mesh can be cleaned, or the worn filter screen can be replaced. After cleaning, the filter screen is reset, the bin cover 8 is closed, and the safety lock 10 is locked to quickly resume production.

[0037] exist Figures 1-3 The limiting components include a safety lock 10 and a safety buckle 11. The safety lock 10 and the safety buckle 11 are symmetrically arranged on the unloading hopper 6 and the hopper cover 8, and the safety lock 10 and the safety buckle 11 are compatible. A strip handle 12 is fixedly connected to the hopper cover 8, and an anti-slip rubber sleeve 13 is fixedly fitted on the outside of the strip handle 12.

[0038] This whole wheat flour fine grinding device, through its structure, ensures that the safety lock 10 and safety buckle 11 fit together to ensure that the lid 8 fits tightly against the unloading chamber 6 when closed, preventing whole wheat flour from leaking out of the gaps during the grinding process. When the filter screen 7 is clogged by bran or fine powder, simply unlock the safety lock 10 and safety buckle 11 without disassembling the entire unloading chamber 6 or the discharge port structure. The operation is convenient. The anti-slip rubber sleeve 13 on the outside of the strip handle 12 increases the friction coefficient between the hand and the handle, improving the safety and effortlessness when opening and closing the lid 8.

[0039] exist Figures 1-4 In the middle: the support assembly includes multiple support columns 14, all of which are fixedly connected to the base 1 through mounting slots, and the other end of the support column 14 is fixedly connected to a support seat 15, and the bottom of the multiple support seats 15 is provided with anti-slip rubber pads 16.

[0040] This whole wheat flour fine grinding device, through its structure, has a support column 14 that is rigidly connected to the base 1 via the mounting groove. The even distribution of multiple support columns 14 can distribute the overall weight of the device to the support base 15, preventing the base 1 from tilting due to uneven force. This ensures the accurate relative position of the first grinding disc 3 and the second grinding disc 4. The support base 15 increases the contact area with the workstation floor, preventing local sinking of the device and improving overall support stability. The anti-slip rubber pad 16 at the bottom can effectively resist the vibration generated during the operation of the grinding device, preventing the base 1 from shifting as a whole. This ensures that the powder in the unloading bin 6 can stably pass through the filter screen 7 for screening, reducing screening deviations caused by vibration.

[0041] exist Figures 1-4 In the middle: The feed pipe 5 is connected to the feed hopper 17, which significantly increases the feed inlet diameter of the raw materials. When the operator feeds the materials, there is no need to accurately align the feed pipe 5 opening, which effectively reduces the spillage of whole wheat raw materials.

[0042] In this embodiment, the grinding device body 2 is a commercially available device known to those skilled in the art. It can be customized or selected according to actual needs. Here we are only using it without making any structural or functional improvements. We will not go into details here. The grinding device body 2 is equipped with a matching control switch. The installation position of the control switch is selected according to actual usage needs to facilitate operation and control by the operator. The technology is already very mature and can be implemented.

[0043] The implementation principle of the whole wheat flour fine grinding device of this utility model embodiment is as follows: First, the base 1 is supported and placed in the use position by the mutual cooperation of multiple support columns 14 and support base 15. Then, the feeding structure is used to achieve efficient feeding. The feeding hopper 17 connected to the feeding pipe 5 increases the feeding diameter. When the operator feeds the material, there is no need to accurately align the pipe opening. The raw material is smoothly introduced into the feeding pipe 5 through the feeding hopper 17 and then enters the inner cavity of the second grinding disc 4. The core grinding function achieves fine processing through the double-layer structure. After the grinding device body 2 is started, the first grinding disc 3 and the second grinding disc 4 cooperate to perform double-layer grinding on the raw material. Compared with the traditional single-stage grinding, it can more fully crush the whole wheat particles and significantly improve the fineness of the finished product. The ground powder enters the discharge chamber 6 through the discharge hole. Under the action of gravity, it is screened by the bottom filter screen 7. The fine powder that meets the standard is discharged through the screen, and the coarse particles that do not meet the standard are retained in the chamber for re-grinding to ensure that the particle size of the finished product is uniform.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
