Description

Technical Field

[0001] This utility model relates to the field of konjac grinding technology, specifically to the grinding structure of a konjac flour grinding machine. Background Technology

[0002] Konjac powder, as the name suggests, is a powder made from konjac. The production process requires grinding equipment to pulverize the konjac into powder. During this process, konjac powder with inconsistent particle sizes mixes together, causing some powder that has already met the grinding requirements to continue being ground, affecting overall efficiency. Therefore, multi-stage grinding devices have been designed; by using sieves, the konjac powder that meets the requirements at each stage is discharged downwards for the next stage of processing, thus improving production efficiency.

[0003] Utility model patent CN222606557U discloses a multi-stage grinding machine for konjac flour. This utility model includes an open-top and bottom cylindrical shell. A flat U-shaped base is connected to the lower end of the cylindrical shell, and a sliding plate is inclinedly arranged inside the base. Multiple layers of bucket-shaped sieve plates are arranged inside the cylindrical shell, with the aperture of the sieve plates gradually decreasing from top to bottom. A main shaft is rotatably arranged at the center of the cylindrical shell, and at least three grinding rollers are respectively arranged on the main shaft above each layer of sieve plates. This utility model features an open upper part of the cylindrical shell with a large opening for convenient feeding; the sliding plate at the bottom discharges the konjac flour quickly and conveniently; the three grinding rollers have different operating modes and grinding effects, working together to ensure grinding efficiency; triangular supports are arranged around the bottom of the sieve plates, providing reliable support and improving the strength of the sieve plates; reinforcing rings provide circumferential reinforcement, giving the sieve plates better resistance to deformation.

[0004] Although the aforementioned utility model can perform multi-stage grinding of konjac, its fixed internal structure makes disassembly inconvenient after grinding, and it is also inconvenient to replace and clean the grinding device after grinding. Therefore, we propose a grinding structure for a konjac flour grinding machine. Utility Model Content

[0005] This utility model provides a grinding structure for a konjac flour grinder to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The grinding structure of the konjac flour grinding machine includes a grinding shell, a rotating mechanism rotatably connected to the lower surface of the grinding shell, a plurality of grinding mechanisms mounted on the rotating mechanism, and a filter mechanism provided on the lower side of each grinding mechanism;

[0008] The rotating mechanism includes a rotating shaft, a pulley installed at the lower end of the rotating shaft, and several limiting grooves opened on the outer surface of the rotating shaft. A lower support sleeve is fitted on the lower end of the outer surface of the rotating shaft, several limiting grooves are opened on the upper side of the outer surface of the rotating shaft, an external thread is opened on the top end of the outer surface of the rotating shaft, a threaded sleeve is threaded on the external thread, and several upper support sleeves are fitted on the upper end of the outer surface of the rotating shaft.

[0009] As a preferred technical solution, the outer surface of the threaded sleeve is provided with anti-slip texture, and the height of the threaded sleeve is less than the length of the external thread section.

[0010] This feature allows users to easily grip the threaded sleeve and control its rotation.

[0011] As a preferred technical solution, the grinding mechanism includes a grinding connecting block, a plurality of grinding rods welded to the outer surface of the grinding connecting block, and a grinding roller installed on the outside of each of the grinding rods.

[0012] As a preferred technical solution, the upper surface of the grinding connecting block is provided with a grinding insertion hole, and a plurality of grinding limiting blocks are welded to the inner surface of the grinding insertion hole.

[0013] As a preferred technical solution, the cross-section of the grinding insertion hole is n-shaped, and the outer side of the lower surface of the grinding connecting block is beveled.

[0014] These three settings ensure that the grinding mechanism rotates along with the rotating mechanism, thereby grinding the konjac located on the filtering mechanism.

[0015] As a preferred technical solution, the filtration mechanism includes a filter connecting block, a filter screen welded to the lower side of the filter connecting block, and several support frames welded to the lower surface of the filter screen. An auxiliary hole is provided on the filter screen at the upper end of one of the support frames, and an auxiliary groove is provided on the side surface of the support frame. A limit block is provided in the auxiliary groove.

[0016] As a preferred technical solution, the filter connecting block includes an outer connecting sleeve and an inner connecting sleeve rotatably connected to the inner side of the outer connecting sleeve. An inner connecting ring is welded to the middle position of the inner surface of the outer connecting sleeve, and a plurality of filter limiting blocks are welded to the inner surface of the inner connecting sleeve. A connecting groove is formed at the middle position of the outer surface of the inner connecting sleeve.

[0017] As a preferred technical solution, the lower end of the outer surface of the outer connecting sleeve is welded to the filter screen, and the cross-section of the filter screen is an isosceles trapezoidal structure that is wider at the top and narrower at the bottom.

[0018] These three settings ensure that the filtration mechanism can grind alongside the grinding mechanism without rotating with the rotating mechanism, and filter out the konjac powder that has reached the grinding standard for storage.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. After grinding konjac, the grinding and filtering mechanisms can be disassembled for cleaning and maintenance, solving the problem that the internal grinding and filtering mechanisms are not easy to clean after grinding in existing products.

[0021] 2. Both the filtration and grinding mechanisms can be detached from the rotating mechanism, allowing for the selection of appropriate filtration and grinding mechanisms based on different grinding precision requirements. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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] Please see Figures 1-7 This embodiment provides a technical solution:

[0036] The grinding structure of the konjac flour grinder includes a grinding shell 100, a rotating mechanism 200 rotatably connected to the lower surface of the grinding shell 100, a number of grinding mechanisms 300 installed on the rotating mechanism 200, and a filter mechanism 400 provided on the lower side of each grinding mechanism 300.

[0037] The rotating mechanism 200 includes a rotating shaft 201, a pulley 202 installed at the lower end of the rotating shaft 201, and several limiting grooves 204 formed on the outer surface of the rotating shaft 201. A lower support sleeve 203 is fitted on the lower end of the outer surface of the rotating shaft 201. Several limiting grooves 204 are formed on the upper side of the outer surface of the rotating shaft 201. An external thread 206 is formed on the top end of the outer surface of the rotating shaft 201. A threaded sleeve 207 is threaded onto the external thread 206. Several upper support sleeves 205 are fitted on the upper end of the outer surface of the rotating shaft 201. Through the above mechanism, the grinding mechanism 300 and the filtering mechanism 400 can be easily disassembled for cleaning and maintenance.

[0038] It should be added that the limiting block 403 is welded to the inner wall of the grinding shell 100, and the upper support sleeve 205 can separate the grinding area composed of the two grinding mechanisms 300 and the filter mechanism 400 located on the upper side and the middle side.

[0039] Furthermore, such as Figure 2 As shown, the outer surface of the threaded sleeve 207 is provided with anti-slip texture. The height of the threaded sleeve 207 is less than the length of the external thread 206 segment, which increases the friction generated when the user grips the outer surface of the threaded sleeve 207.

[0040] Furthermore, such as Figure 3As shown, the grinding mechanism 300 includes a grinding connecting block 301, a plurality of grinding rods 302 welded to the outer surface of the grinding connecting block 301, and a grinding roller 303 installed on the outside of each grinding rod 302. The three grinding rollers 303 have different grinding patterns on their outer surfaces according to the degree of grinding.

[0041] In this embodiment, as Figure 4 As shown, the upper surface of the grinding connecting block 301 is provided with a grinding insertion hole 3011, and a number of grinding limiting blocks 3012 are welded to the inner surface of the grinding insertion hole 3011. The cross-section of the grinding insertion hole 3011 is n-shaped. The outer side of the lower surface of the grinding connecting block 301 is beveled to increase the fit between the grinding connecting block 301 and the upper surface of the filter screen 405.

[0042] In this embodiment, as Figure 5 As shown, the filter mechanism 400 includes a filter connecting block 401, a filter screen 405 welded to the lower side of the filter connecting block 401, and several support frames 404 welded to the lower surface of the filter screen 405. An auxiliary hole 402 is provided on the filter screen 405 at the upper end of one of the support frames 404. An auxiliary groove is provided on the side surface of the support frame 404. A limiting block 403 is provided in the auxiliary groove. The limiting block 403 is slidably connected in the limiting groove 204.

[0043] In this embodiment, as Figure 5 As shown, the filter connecting block 401 includes an outer connecting sleeve 4011 and an inner connecting sleeve 4013 rotatably connected to the inner side of the outer connecting sleeve 4011. An inner connecting ring 4012 is welded to the middle position of the inner surface of the outer connecting sleeve 4011. Several filter limiting blocks 4015 are welded to the inner surface of the inner connecting sleeve 4013. A connecting groove 4014 is opened at the middle position of the outer surface of the inner connecting sleeve 4013. The inner connecting ring 4012 is rotatably connected in the connecting groove 4014.

[0044] In this embodiment, as Figure 5 As shown, the lower end of the outer surface of the outer connecting sleeve 4011 is welded to the filter screen 405. The cross-section of the filter screen 405 is an isosceles trapezoidal structure that is wider at the top and narrower at the bottom, which makes it easier for the konjac powder located on the periphery of the filter screen 405 to slide down to the middle position of the filter screen 405 under the action of gravity to continue to be ground.

[0045] It is worth noting that the structure and working principle of the grinding shell 100, pulley 202, grinding rod 302, grinding roller 303, and support frame 404 involved in this embodiment are all technologies that have been disclosed in the prior art, and will not be described in detail here.

[0046] In this embodiment of the konjac flour grinder, during specific use, after the grinding action is completed, first, hold the rotating shaft 201 with one hand, and rotate the threaded sleeve 207 with the other hand until it is removed from the external thread 206. Then, the grinding mechanism 300 and the filtering mechanism 400 can be removed layer by layer for cleaning. After cleaning, the grinding limit block 3012 and the filtering limit block 4015 are reinserted into the limiting groove 204. When the pulley 202 starts to rotate due to external influence, the rotating shaft 201 rotates with the pulley 202. During rotation, the grinding connecting block 301 is inserted into the limiting groove 204. In this way, the grinding mechanism 300 rotates together with the rotating shaft 201. Although the filter limiting block 4015 is also in the limiting groove 204, the inner connecting sleeve 4013 and the outer connecting sleeve 4011 in the filter connecting block 401 are rotatably connected. Furthermore, one of the support frames 404 on the lower side of the filter screen 405 is slidably connected to the limiting block 403. The limiting block 403 is welded to the inner wall of the grinding shell 100 and cannot move, thus preventing the filter screen 405 from rotating. This allows the grinding mechanism 300 to rotate smoothly while the filter mechanism 400 does not rotate, enabling the grinding mechanism 300 to grind the konjac smoothly.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
