Description

Technical Field

[0001] The utility model relates to the technical field of flour processing, and more specifically, to a high-precision flour screening device for flour processing. Background Art

[0002] Flour is the main raw material for making pasta. High-refined flour is needed in the production of some pasta. After the initial grinding, some coarse flour will be mixed in the flour, which generally needs to be screened using a screening device. At present, flour screening is generally done manually with a sieve plate, resulting in low screening efficiency. In addition, flour often leaks during the screening process, and the flour will float in the air, causing certain waste and even certain risks.

[0003] The utility model patent with patent publication number CN220160072U discloses a high-precision flour screening device for flour processing, including a sieve housing, a mounting plate is connected through the top of the sieve housing, the inner side wall of the sieve housing is fixedly connected with the mounting plate and the mounting frame, a driving mechanism is provided on the top of the mounting plate, a transmission mechanism is provided on the inner top of the sieve housing, a rotating mechanism is provided on the inner side wall of the sieve housing, a sliding mechanism is provided in the mounting frame, and a first collecting frame and a second collecting frame are fixedly connected to the inner bottom of the sieve housing. The utility model has a reasonable structural design. By setting a grinding mechanism and a sliding mechanism, when the staff adds flour blocks to the device, the grinding rod rotating in both directions can fully grind and break up the flour blocks. At the same time, through the setting of the sliding device, the staff can drive the rotating mechanism and the sliding mechanism to operate through the transmission of the transmission belt during actual use, and drive the screen to oscillate and slide up and down.

[0004] However, in actual use, since the structure uses an up and down oscillation method to screen the flour, the flour is easy to float during the oscillation process, causing the screened flour to mix with the flying flour again, thereby reducing the flour screening accuracy. Therefore, a high-precision flour screening equipment for flour processing is proposed. Utility Model Content

[0033] In specific implementation, the flour to be sifted is poured into the feed port 2, and then the sealing cover 3 is closed for sealing, and the driving mechanism 5 is started. Under the connection of the connecting rod 8, the screening box 7 is moved back and forth on the two cross rails 6. In the process of the screening box 7 moving back and forth, the flour is sifted. In the screening process, the top of the screening box 7 is sealed to prevent the flour from flying, and the sifted flour can automatically fall along the conical surface to the discharge pipe 4 for discharge, thereby improving the fineness of the flour screening.

[0034] As attached Figure 2 and Figure 3 As shown, the driving mechanism 5 includes a motor 501, and the motor 501 is installed outside the cabin 1;

[0035] A rotating rod 502, one end of which is connected to the output end of the motor 501;

[0036] The rotating disk 503 is coaxially mounted on the other end of the rotating rod 502 .

[0037] The rotating disk 503 is in a disc structure, and a towing rod is installed at the edge of the rotating disk 503 , and the towing rod is movably connected to one end of the connecting rod 8 .

[0038] During specific implementation, the motor 501 is operated to rotate the rotating rod 502, thereby causing the turntable 503 to rotate. During the rotation of the turntable 503, the drag rod cyclically pushes and pulls the connecting rod 8, thereby cyclically pushing and pulling the screening box 7, so that the screening box 7 can always move under the push and pull force.

[0039] Embodiment 2

[0040] As attached Figure 1 , Figure 5 , Figure 6 and Figure 7 A high-precision flour screening equipment for flour processing shown in the figure includes a machine warehouse 1, a feed port 2 is arranged at the top of the machine warehouse 1, a sealing cover 3 is installed on the feed port 2, a discharge pipe 4 is arranged at the bottom of the machine warehouse 1, cross rails 6 are symmetrically installed at the top of the interior of the machine warehouse 1, screening boxes 7 are slidably supported on two of the cross rails 6, slides 10 are installed on both sides of the screening box 7, each of the slides 10 is slidably matched with the corresponding cross rail 6, and a sieve plate 11 is installed at the bottom end of the screening box 7, a driving mechanism 5 is installed in the machine warehouse 1, and the driving mechanism 5 is connected and matched with one end of the screening box 7, the bottom end of the interior of the machine warehouse 1 is a conical structure, and a valve is arranged on the discharge pipe 4.

[0041] During specific implementation, the flour to be screened is poured into the feed port 2, and then the sealing cover 3 is closed for sealing, and the driving mechanism 5 is started. The driving mechanism 5 pushes one side of the screening box 7, and the other side of the screening box 7 squeezes the rebound component 13, so that the elastic sleeve 1304 inside the rebound component 13 accumulates elastic potential energy. When the force of the driving mechanism 5 is reduced, the potential energy is released to push the screening box 7, so that the screening box 7 can move back and forth on the two cross rails 6. In the process of the screening box 7 moving back and forth, the flour is screened, and in the screening process, since the top of the screening box 7 is sealed, the flour can be prevented from flying, and the screened flour can automatically fall along the conical surface to the discharge pipe 4 for discharge, thereby improving the fineness of flour screening.

[0042] As attached Figure 5 , Figure 6 and Figure 7 As shown, the driving mechanism 5 includes a motor 501, and the motor 501 is installed outside the cabin 1;

[0043] A rotating rod 502, one end of which is connected to the output end of the motor 501;

[0044] The rotating disk 503 is coaxially mounted on the other end of the rotating rod 502 .

[0045] The turntable 503 is in a cam structure, and the edge of the turntable 503 is connected to one side of the screening box 7, and the corresponding second connecting frame 14 is symmetrically arranged on the other side of the screening box 7. The two second connecting frames 14 are commonly connected to a rebound component 13, and the bottom end of the rebound component 13 is supported by a support frame 12, and the support frame 12 is installed in the machine room 1.

[0046] During specific implementation, the motor 501 is operated to rotate the rotating rod 502, thereby causing the turntable 503 to rotate. During the rotation of the turntable 503, one side of the screening box 7 is pushed cyclically, so that when the screening box 7 is away from the position of the driving mechanism 5, it is acted upon by the force of the driving mechanism 5. When the screening box 7 moves back, the potential energy accumulated by the rebound assembly 13 is released.

[0047] As attached Figure 6 As shown, the rebound assembly 13 includes a support rod 1301, and the support rod 1301 is installed on the support frame 12;

[0048] Two sliding sleeves 1302, both of which are sleeved on the support rod 1301;

[0049] Two movable rods 1303, one end of each movable rod 1303 is movably connected to the corresponding sliding sleeve 1302, and the other end of each movable rod 1303 is movably connected to the corresponding second connecting frame 14;

[0050] Two elastic sleeves 1304 are respectively sleeved on two ends of the support rod 1301 , and the two elastic sleeves 1304 are respectively pressed and matched with the corresponding sliding sleeves 1302 .

[0051] In specific implementation, when the potential energy accumulated by the two elastic sleeves 1304 is released, the two sliding sleeves 1302 on the support rod 1301 are pushed respectively, so that the two sliding sleeves 1302 are close to each other, and the angle between the two movable rods 1303 is reduced, so that the hungry screening box 7 moves in the direction of the driving mechanism 5, thereby realizing automatic return.

[0052] The difference between the above two embodiments provided by the present invention is that the first embodiment always needs to perform work on the screening box 7, while the second embodiment only needs to perform unidirectional work on the screening box 7.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
