Description

Technical Field

[0001] This application relates to the field of instant noodle processing, and in particular to a flour vibrating screen. Background Technology

[0002] Instant noodles, also known as fast food noodles or ramen, are a type of noodle food that can be cooked quickly by soaking in hot water. With the fast pace of life and the need for travel, instant noodles have long become an indispensable and convenient food in modern life. Flour, as a common powdered material, is a crucial raw material for making instant noodles and other foods, and its selection quality directly affects the quality of the final product.

[0003] In the field of flour screening, traditional screening methods typically include manual screening and simple mechanical vibration screening. Manual screening requires workers to hold the sieve and repeatedly shake it to force the flour through. While this method requires simple equipment and is low-cost, it demands continuous operation and is labor-intensive. Furthermore, due to the manual operation, its efficiency is extremely low, and screening accuracy is difficult to guarantee, easily leading to missed or over-screening. Simple mechanical vibration screening uses a motor to drive the sieve to vibrate, thus screening the flour. Compared to manual screening, this method improves screening efficiency to some extent; however, it lacks effective stirring and sealing measures. During screening, flour tends to accumulate on the sieve, resulting in incomplete screening and affecting the screening effect. Utility Model Content

[0004] To ensure thorough screening and improve screening results, this application provides a flour vibrating screen.

[0005] The flour vibrating screen provided in this application adopts the following technical solution: A flour vibrating sieve includes a support frame and a storage component mounted on the support frame with an opening at the top. A sieving component with an open top surface is installed at the top opening of the storage component. A screen is provided on the bottom surface of the sieving component. A vibrating motor is installed on the outer side wall of the storage component. A cover for sealing the top opening of the sieving component is provided above the sieving component. A lifting mechanism for driving the cover to rise and fall is installed on the support frame. A stirring component is installed at the bottom of the cover. A drive component for driving the stirring component to rotate is connected to the cover.

[0006] By adopting the above technical solution, during the flour sieving process, the flour is placed inside the sieving component, and the cover is lowered and sealed at the upper opening of the sieving component by the lifting mechanism. The driving component drives the stirring component to rotate, stirring the flour inside the sieving component and making the flour fully dispersed. At the same time, the vibration motor on the outer wall of the receiving component is started, causing the sieving component and the screen to vibrate. Under the combined action of stirring and vibration, qualified flour passes through the screen and falls into the receiving component, ensuring more thorough sieving and improving the sieving effect.

[0007] Preferably, the support frame is connected to a support rod located above the screening component, and the lifting mechanism includes a lifting cylinder fixedly connected to the support rod. The piston rod of the lifting cylinder is set downward and fixedly connected to a guide member. The guide member includes two guide rods that penetrate the support rod vertically, and the lower end of each guide rod is fixedly connected to the upper top surface of the cover.

[0008] By adopting the above technical solution, when it is necessary to open the cover, the piston rod of the lifting cylinder retracts upward, driving the guide rod of the guide component to move vertically upward on the support rod, thereby driving the cover to move upward and realizing the opening of the cover; when it is necessary to close the cover, the piston rod of the lifting cylinder extends downward, driving the guide rod of the guide component to move vertically downward on the support rod, thereby driving the cover to move downward and realizing the sealing of the cover to the upper opening of the screening component.

[0009] Preferably, the driving component includes a drive motor mounted on the guide member, and a stirring shaft is fixedly connected to the output shaft of the drive motor. The stirring shaft vertically penetrates the support rod and the cover and is fixedly connected to a horizontally arranged stirring rod.

[0010] By adopting the above technical solution, when the upper opening of the sealing sieve component is sealed, the drive motor is started to drive the stirring shaft to rotate. The stirring shaft vertically downwards passes through the support rod and the sealing cover and enters the interior of the sieve component, so that the horizontal stirring rod fixedly connected to the stirring shaft rotates and stirs inside the sieve component. This can reduce the accumulation of flour on the screen, promote flour sieving, and improve sieving efficiency.

[0011] Preferably, a drive cylinder is fixedly connected to the guide member, and the piston rod of the drive cylinder is vertically arranged and fixedly connected to the drive motor.

[0012] By adopting the above technical solution, the vertical position of the stirring component in the sieving component can be flexibly adjusted to better stir the flour in the sieving component and improve the flour sieving effect.

[0013] Preferably, a rotating shaft is rotatably connected to the support frame, one end of the support rod is fixedly connected to the rotating shaft, and an adjusting motor is fixedly connected to the support frame, with the output shaft of the adjusting motor being coaxially fixed with the rotating shaft.

[0014] By adopting the above technical solution, the motor drives the rotating shaft to rotate, which in turn drives the support rod fixedly connected to the rotating shaft to rotate. This causes the cap and stirring components located above the sieving component to rotate away from the sieving component, making it easier to add the flour to be sifted into the sieving component.

[0015] Preferably, the bottom surface of the screening component is provided with a snap-fit ​​groove, which snaps into the upper end of the storage component.

[0016] By adopting the above technical solution, the screening component is connected to the upper end of the storage component through the snap-fit ​​groove on the bottom surface, thus achieving a stable connection between the screening component and the storage component. This facilitates the installation and disassembly of the screening component and is beneficial for subsequent maintenance and cleaning.

[0017] Preferably, the storage component includes a storage hopper that engages with a snap-fit ​​groove, and a discharge pipe is fixedly connected to the bottom end of the storage hopper.

[0018] By adopting the above technical solution, it is easy for flour to fall from the sieving component into the collection hopper, and the setting of the unloading pipe makes it convenient to discharge the sifted flour in the collection hopper.

[0019] Preferably, the storage component is detachably connected to the support frame.

[0020] By adopting the above technical solution, it is easy to disassemble and install the storage components, and convenient to clean, replace or repair them.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. Ensure thorough screening to improve screening effectiveness; 2. To better mix the flour inside the sieving unit and improve the flour sieving effect; 3. Easy to install and disassemble screening components, facilitating subsequent maintenance and cleaning.

[0025] The following is in conjunction with the appendix Figures 1-2 This application will be described in further detail.

[0026] This application discloses a flour vibrating screen. (Refer to...) Figure 1 and Figure 2 The flour vibrating screen includes a support frame 1, a storage component 2, a screening component 3, a vibrating motor 4, a cover 5, a lifting mechanism 6, a mixing component 7, and a driving component 8. The storage component 2 is mounted on the support frame 1 and includes a storage hopper 21 with an open top. A discharge pipe 22 is fixedly connected to the bottom of the storage hopper 21, and a valve is installed on the discharge pipe 22. The screening component 3 is installed at the upper opening of the storage component 2. The vibrating motor 4 is fastened to the outer wall of the storage component 2 with screws.

[0027] The cover 5 is positioned above the sieving component 3 and can be raised and lowered by the lifting mechanism 6. The stirring component 7 is installed at the bottom of the cover 5, and the driving component 8 is connected to the cover 5 and drives the stirring component 7 to rotate. The vibrating motor 4 causes the screen 31 to vibrate and sieve the flour. The cover 5 seals the receiving component 2 to limit the flour from flying around, and the stirring component 7 stirs to reduce the accumulation of flour. The three components work together to improve the sieving effect.

[0028] The support frame 1 is the supporting structure for the entire flour vibrating screen, usually made of metal, possessing a certain strength and stability. It can be a frame structure, composed of multiple horizontal and vertical bars welded or bolted together. The shape and size of the support frame 1 can be designed according to actual needs to accommodate different specifications of the storage components 2 and screening components 3.

[0029] Reference Figure 1 and Figure 2 The sieving component 3 is a hollow cylinder with an open top surface, and a screen 31 is provided on the bottom surface of the sieving component 3. A locking groove is provided at the bottom of the sieving component 3, which engages with the upper end of the receiving component 2. The screen 31 is a key component for flour sieving; it can be selected with different mesh sizes according to the flour sieving requirements to ensure that flour meeting the particle size requirements is sieving. The screen 31 can be made of metal, such as stainless steel wire mesh, which has high strength and wear resistance. The sieving component 3 can be made of plastic or metal, and its shape can be round or square to adapt to different application scenarios.

[0030] The vibration motor 4 is fastened to the outer wall of the storage component 2 by screws. When the vibration motor 4 is started, it will drive the storage component 2 and the sieving component 3 to vibrate together, thereby causing the flour on the sieve 31 to jump continuously, promoting the flour to pass through the sieve 31. The vibration motor 4 can be selected with appropriate power and model according to the weight and size of the sieving component 3 and the storage component 2 to ensure the vibration effect.

[0031] A support rod 11 is connected to the support frame 1 and is located above the screening component 3. The support rod 11 is arranged horizontally. The lifting mechanism 6 includes a lifting cylinder 61 fixedly connected to the support rod 11. The piston rod of the lifting cylinder 61 is arranged downward and fixedly connected to a guide member 62.

[0032] Reference Figure 1 and Figure 2 The guide member 62 includes two vertically penetrating guide rods 621 through the support rod 11, with a fixed rod 622 fixedly connected between the two guide rods 621. The lower end of each guide rod 621 is fixedly connected to the upper top surface of the cover 5. When the piston rod of the lifting cylinder 61 extends or retracts, it drives the cover 5 to rise or fall through the guide member 62. The function of the guide rods 621 is to ensure the stability of the cover 5 during lifting and falling, preventing the cover 5 from shifting during the lifting process. The guide rods 621 can be cylindrical metal rods with smooth surfaces to reduce friction with the support rod 11.

[0033] The driving component 8 includes a driving cylinder 81 fixedly connected to the fixed rod 622. The piston rod of the driving cylinder 81 is vertically upward and fixedly connected to a driving motor 82. The output shaft of the driving motor 82 is vertically downward. The stirring component 7 includes a stirring shaft 71 coaxially fixedly connected to the output shaft of the driving motor 82. The stirring shaft 71 vertically downward passes through the support rod 11 and the cover 5 and is fixedly connected to two horizontally arranged stirring rods 72.

[0034] When the drive motor 82 starts, the output shaft of the drive motor 82 will drive the stirring shaft 71 and the stirring rod 72 to rotate, thereby realizing the stirring of the flour on the screen 31.

[0035] When it is necessary to adjust the vertical height of the stirring rod 72, the drive motor 82 is started. The drive cylinder 81 can drive the drive motor 82 and the stirring component 7 to move up and down, further adjusting the contact position between the stirring component 7 and the flour on the sieve 31, thereby improving the stirring effect.

[0036] Reference Figure 1 and Figure 2 A rotating shaft 12 is rotatably connected to the support frame 1. The rotating shaft 12 is set vertically upward. One end of the support rod 11 is fixedly connected to the upper end of the rotating shaft 12. An adjusting motor 13 is fixedly connected to the support frame 1. The output shaft of the adjusting motor 13 is coaxially fixed with the lower end of the rotating shaft 12.

[0037] Start the regulating motor 13. The output shaft of the regulating motor 13 can drive the rotating shaft 12 to rotate, thereby causing the support rod 11 and the cover 5 to rotate around the rotating shaft 12. This allows the cover 5 to be removed when it is necessary to clean the sieving component 3 or replace the screen 31, making operation convenient. It also makes it easy to add flour to be sifted into the sieving component 3.

[0038] The implementation principle of a flour vibrating screen according to this application embodiment is as follows: the flour vibrating screen uses a vibrating motor 4 to vibrate the screen 31, the sealing cover 5 seals the screening component 3 to reduce flour flying, and the stirring component 7 rotates and stirs the flour under the drive component 8, limiting flour accumulation and effectively improving the efficiency and accuracy of flour screening. The lifting mechanism 6, the drive cylinder 81, and the adjusting motor 13 allow for flexible adjustment of the positions of the sealing cover 5 and the stirring component 7, facilitating use and maintenance. Compared with traditional flour screening methods...

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
