On the contrary, the embodiments of the present application include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0030] The flour screening device for producing noodles according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0031] like Figures 1 to 8 As shown, the flour screening device for noodle production according to the embodiment of the present application may include a housing 10 , a driving component 20 , a filter screen 30 , a rotating roller 40 and a collecting plate 50 .

[0032] A feed port 11 is disposed at the top of the shell 10 , and a discharge port 12 is disposed at the bottom of the shell 10 .

[0033] It should be noted that a spiral feeding structure may be provided in the discharge port 12 to assist in discharging the material. The spiral feeding structure is a prior art and will not be described in detail herein.

[0034] The rotating roller 40 is horizontally and rotatably disposed inside the housing 10 .

[0035] The rotating roller 40 is located below the feed inlet 11 .

[0036] It should be noted that the rotating roller 40 can be rotatably connected to the inside of the housing 10 via a rotating shaft.

[0037] The driving component 20 is mounted on the outer side wall of the housing 10 , and a driving shaft of the driving component 20 passes through the housing 10 and is coaxially connected to the rotating roller 40 .

[0038] The driving component 20 may be a rotary motor.

[0039] The filter screen 30 is disposed inside the housing 10 and is located below the rotating roller 40 . The cross-sectional shape of the filter screen 30 is U-shaped.

[0040] The lowest point of the filter screen 30 is arranged opposite to the lowest point of the rotating roller 40 .

[0041] It should be noted that the mesh size of the filter holes on the filter 30 is selected according to actual needs and will not be described in detail here; there is a height difference between the rotating roller 40 and the filter 30, and the numerical value of the height difference is selected according to actual needs and will not be described in detail here.

[0042] It should be noted that the outer side of the filter screen 30 is sealedly connected to the inner wall of the housing 10 .

[0043] The collecting plate 50 is tiltedly disposed in the housing 10 , and the collecting plate 50 is located below the filter screen 30 .

[0044] The bottom end of the collecting plate 50 is arranged opposite to the discharge port 12 , so that the flour screened on the collecting plate 50 can be taken out through the discharge port 12 .

[0045] An upper material taking door 13 is provided on the side wall of the housing 10 , and the upper material taking door 13 is arranged opposite to the filter screen 30 .

[0046] It should be noted that relevant personnel can take out the materials on the filter screen 30 through the upper material taking door 13 .

[0047] In one embodiment of the present application, Figure 3 As shown, a vibration component 51 is installed on the bottom surface of the collecting plate 50.

[0048] The vibration component 51 may be a vibration motor.

[0049] It should be noted that the vibration component 51 is used to drive the collecting plate 50 to vibrate, so that the flour on the collecting plate 50 can be gathered near the discharge port 12.

[0050] Specifically, in the actual operation process, the relevant personnel pour the flour to be screened into the shell 10 through the feed port 11, ensure that the driving component 20 is connected and in standby state; start the driving component 20 to make the rotating roller 40 start to rotate, and the flour is evenly dispersed and falls onto the filter screen 30 under the action of the rotating roller 40. Through the screening effect of the filter screen 30, impurities are trapped on the filter screen 30, and pure flour falls onto the collecting plate 50 through the filter screen 30; the flour on the collecting plate 50 is continuously vibrated under the action of the vibrating component 51, and gradually gathers near the discharge port 12. When a certain amount is collected, the flour can be taken out through the discharge port 12; after the screening is completed, the material on the filter screen 30 can be taken out and cleaned by opening the upper material taking door 13.

[0051] Impurities in the flour are removed by the filter 30, thereby improving the purity and quality of the flour; by providing the rotating roller 40, the flour can be dispersed more evenly and fall onto the filter 30, thereby preventing the accumulation of flour and causing the filter 30 to be blocked, thereby improving the filtering efficiency of the flour.

[0052] In one embodiment of the present application, Figure 3 As shown, the interior of the rotating roller 40 is hollow, and the side wall of the rotating roller 40 is densely covered with sieve holes.

[0053] The aperture of the mesh on the rotating roller 40 is larger than the aperture of the filter holes on the filter screen 30 .

[0054] It should be noted that the mesh number and position distribution of the sieve holes on the rotating roller 40 are selected according to actual needs, so they are not shown in the figure. The mesh number and position distribution of the sieve holes are selected according to actual needs and are not described in detail here.

[0055] Further, in one embodiment of the present application, Figure 4 As shown, a plurality of scrapers 60 are disposed on the outer wall of the rotating roller 40 , and the scrapers 60 and the filter screen 30 are staggered.

[0056] The width direction of the scraper 60 is the same as the axial direction of the rotating roller 40 .

[0057] It should be noted that the plurality of scrapers 60 may be 5, 6, 7, 8, 9 scrapers 60, etc. The specific number is selected according to actual needs and will not be described in detail here.

[0058] It should be noted that the length and height of the scraper 60 are selected according to actual needs and will not be described in detail again.

[0059] In order to clearly explain the above embodiment, in one embodiment of the present application, Figure 4 and Figure 5 As shown, the scraper 60 includes an inner plate 61 , an outer plate 62 and a compression spring 63 .

[0060] The outer plate 62 is hollow inside.

[0061] One end of the inner plate 61 is connected to the filter screen 30 , and the other end of the inner plate 61 is slidably inserted into the outer plate 62 .

[0062] The compression spring 63 is located inside the outer plate 62 , and two ends of the compression spring 63 are connected to the inner plate 61 and the outer plate 62 respectively.

[0063] It should be noted that the outer plate 62 and the inner plate 61 are sealed and slidably connected; the number of the compression spring 63 is at least one.

[0064] It should be noted that in the initial state, the scraper 60 is in an extended state. When the scraper 60 contacts the filter 30 , the scraper 60 can adjust its length accordingly, and the shortest length of the scraper 60 is not greater than the shortest distance between the filter 30 and the rotating roller 40 .

[0065] It can be understood that after the flour enters the shell 10 from the feed port 11, it is first preliminarily screened through the sieve holes on the rotating roller 40 to remove some large particle impurities; the flour that has been preliminarily screened falls onto the filter 30, and is further screened by the filter 30 to remove finer impurities; at the same time, some of the flour will enter the rotating roller 40 to prevent all the flour from accumulating on the filter 30 when there is too much flour; as the rotating roller 40 rotates, the scraper 60 continuously scrapes the surface of the filter 30, and the scraper 60 can adjust its length according to the state of the filter 30 during the scraping process, maintain proper contact with the filter 30, prevent flour from accumulating and clogging the filter 30, and assist the flour to pass through the filter 30 better.

[0066] By providing a hollow rotating roller 40, part of the flour enters the rotating roller 40 and will not be completely accumulated on the filter screen 30, thereby reducing the pressure on the filter screen 30 and the degree of flour accumulation; through the preliminary screening of the rotating roller 40 and the continuous scraping of the scraper 60, the flour filtering efficiency is significantly improved; the provision of the scraper 60 effectively prevents the accumulation and blockage of flour on the filter screen 30, ensuring the continuous smoothness of the filter screen 30.

[0067] In one embodiment of the present application, Figure 6 As shown, a vibration column 70 is placed inside the rotating roller 40.

[0068] It should be noted that the length and cross-sectional dimensions of the vibration column 70 are selected according to actual needs and will not be described in detail here.

[0069] Further, in one embodiment of the present application, Figure 6 and Figure 7 As shown, the cross-sectional shape of the vibration column 70 is a polygon.

[0070] The cross-sectional shape of the vibration column 70 may be a pentagon.

[0071] It can be understood that when the rotating roller 40 rotates under the drive of the driving component 20, the internal vibration column 70 produces uneven contact and collision with the inner wall of the rotating roller 40 due to the characteristics of the polygonal cross-section. This uneven contact and collision causes the vibration column 70 to continuously hit the rotating roller 40 during the rotation process, thereby generating vibration; the vibration is transmitted to the filter screen 30 and the scraper 60 through the rotating roller 40, so that the entire screening device is in a slight vibration state.

[0072] The vibration effect promotes the flow and dispersion of flour, reduces the possibility of blockage, and significantly improves the filtering efficiency; the setting of the vibration column 70 and the generation of the vibration effect effectively reduce the risk of flour accumulation and blockage on the rotating roller 40 and the filter screen 30; at the same time, the rolling vibration column 70 can squeeze out part of the flour inside the rotating roller 40, avoiding the flour from staying in the rotating roller 40 for too long, thereby improving the flour screening efficiency.

[0073] In one embodiment of the present application, Figure 6 and Figure 8 As shown, a plurality of air storage bags 80 are disposed inside the rotating roller 40 .

[0074] The material of the air storage bag 80 can be food-grade silicone.

[0075] It should be noted that the plurality of air storage bags 80 may be 5, 10, 15, 20, 25 air storage bags 80, etc. The specific number and position distribution are selected according to actual needs and will not be described in detail here.

[0076] It should be noted that the shape of the air bag 80 in the initial state can be hemispherical or elliptical, and the air bag 80 can return to its original shape under the action of its own elastic force after being squeezed. The specific structure of the air bag 80 is prior art and will not be described in detail here.

[0077] It can be understood that when the rotating roller 40 rotates driven by the driving component 20, the vibration column 70 moves inside the rotating roller 40 and passes through the air bag 80; due to the elasticity and shape characteristics of the air bag 80, when the vibration column 70 passes by, the air bag 80 will be squeezed and deformed; then, under the action of the elastic force of the air bag 80 itself, it will quickly return to its original shape and push the vibration column 70 toward the inner wall of the rotating roller 40; this process will occur repeatedly, causing the vibration column 70 to generate more complex and violent vibrations on the inner wall of the rotating roller 40, and the vibration is transmitted to the filter screen 30 and the scraper 60 through the rotating roller 40, thereby improving the vibration effect and filtration efficiency of the entire screening device.

[0078] The provision of the air bag 80 makes the vibration generated by the vibration column 70 on the inner wall of the rotating roller 40 more complex and intense, which helps to further promote the flow and dispersion of flour; the enhanced vibration effect reduces the risk of flour accumulation and clogging on the filter screen 30, and improves the filtration efficiency and production stability; flour can pass through the filter screen 30 faster, shortening the production cycle and improving production efficiency; the air bag 80 acts as a buffer layer to reduce the noise and wear generated during the vibration process, and extend the service life of the equipment.

[0079] Further, in one embodiment of the present application, Figure 6 As shown, the air storage bag 80 is provided with an air intake check valve 81 .

[0080] One end of the air intake check valve 81 is communicated with the interior of the air storage bag 80 , and the other end of the air intake check valve 81 is communicated with the interior space of the rotating roller 40 .

[0081] The air intake check valve 81 is located at one end of the air storage bag 80 close to the axis of the rotating roller 40 .

[0082] It should be noted that the gas in the internal space of the rotating roller 40 can enter the interior of the air storage bag 80 through the air intake check valve 81 .

[0083] A plurality of gas outlet one-way valves 41 are disposed on the housing 10 , and the number of the gas outlet one-way valves 41 is the same as the number of the air storage bags 80 and they correspond one to one.

[0084] One end of the air outlet check valve 41 is communicated with the interior of the air storage bag 80 , and the other end of the air outlet check valve 41 is communicated with the external space of the rotating roller 40 .

[0085] It should be noted that the gas inside the air storage bag 80 can enter the external space of the rotating roller 40 through the gas outlet one-way valve 41 .

[0086] In one embodiment of the present application, Figure 6 As shown, a return spring 90 is disposed inside the air storage bag 80 .

[0087] One end of the return spring 90 is connected to the rotating roller 40 , and the other end of the return spring 90 is connected to the air storage bag 80 .

[0088] It should be noted that one end of the return spring 90 close to the axis of the rotating roller 40 is connected to the inner wall of one end of the air storage bag 80 close to the axis of the rotating roller 40 .

[0089] It can be understood that when the rotating roller 40 rotates under the drive of the driving component 20, the air bag 80 is squeezed by the vibration column 70 and deformed. At this time, the gas inside the air bag 80 is discharged to the external space of the rotating roller 40 through the air outlet one-way valve 41, and the gas discharged from the air bag 80 can be blown to the filter screen 30, thereby assisting the flour on the filter screen 30 to pass through the filter screen 30, and at the same time avoiding the phenomenon of some flour being compacted and agglomerated; when the air bag 80 needs to be restored to its original state, the air inlet one-way valve 81 opens, allowing the gas in the internal space of the rotating roller 40 to enter the air bag 80. This periodic gas intake and discharge process enables the air bag 80 and the vibration column 70 to produce more complex and intense vibrations, thereby improving the vibration effect and filtration efficiency of the screening device.

[0090] By setting the air inlet check valve 81 and the air outlet check valve 41, the orderly inflow and outflow of gas inside the air storage bag 80 is achieved, resulting in a more complex and intense vibration effect; the enhanced vibration effect promotes the fluidity and dispersion of flour, reduces the risk of clogging, and improves the filtration efficiency and production efficiency; reduces the accumulation and agglomeration of flour inside the equipment, and reduces the difficulty and cost of cleaning and maintenance; the setting of the air inlet check valve 81 and the air outlet check valve 41 enables the air storage bag 80 to maintain a stable shape and elasticity during the vibration process, thereby improving the stability and reliability of the entire equipment; by setting the reset spring 90, the air storage bag 80 can be better assisted in resetting, thereby improving the stability of the equipment operation.

[0091] In summary, the flour screening device for noodle production of the embodiment of the present application promotes the flow and dispersion of flour during the screening process, avoids excessive flour accumulation on the filter mesh 30, reduces the possibility of clogging of the filter mesh 30, and improves the filtering efficiency of flour.
