Description

TECHNICAL FIELD

[0001] The utility model relates to the field of food production screening, specifically to a screening device for food production. BACKGROUND

[0002] Food production is a complete process of converting various food materials or raw materials into food that can meet people's eating needs through a series of meticulous and orderly processing procedures. This process covers many key links such as careful selection of raw materials, professional processing procedures, proper packaging of products, and finally storage and transportation. Each link is closely linked and influences each other, and together ensures the safety and high quality of food from the source to the table.

[0003] In the field of food production, screening devices are very common and indispensable equipment. A common screening device for food production on the market usually consists of a feed inlet, a screen, a vibrating component, a collection tank, and a driving device. It plays a significant role in precise material separation, product quality improvement, and smooth and efficient production process, effectively promoting the orderly development and high-quality completion of food production operations.

[0004] However, the current common screening device for food production on the market has some problems in actual use. Different types of food raw materials often require different specifications of screen to perform screening operations. The existing screen is mostly fixed on the device body by multiple bolts. When replacing the screen, the entire operation process is extremely tedious, complex, and inconvenient, which seriously affects the overall efficiency of the screening operation. Therefore, further improvement is needed. SUMMARY

[0005] Therefore, the utility model aims to provide a screening device for food production to solve the technical problems mentioned in the background.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a screening device for food production, comprising a device body, a screen, and a screen frame, a rotating sleeve is rotatably installed inside the device body, a worm wheel is fixedly installed at the end of the rotating sleeve, an installation column is rotatably installed inside the device body and threadedly connected with the worm wheel, a limiting block is fixedly installed at the end of the installation column, an installation groove and a limiting groove corresponding to the limiting block are formed in the outer wall of the screen frame, a worm is rotatably installed inside the device body and corresponds to the worm wheel, a first bevel gear is fixedly installed on the outer wall of the end of the worm, a transmission rod is rotatably installed inside the device body, a second bevel gear corresponding to the first bevel gear is fixedly installed on the outer wall of the end of the transmission rod, and a rotating disc is fixedly installed at the end of the worm.

[0007] By adopting the above technical solution, the screen replacement process becomes extremely convenient and efficient. Operators only need to rotate the turntable to cause the mounting column to drive the limiting block to rotate and lift precisely, thereby quickly and easily releasing the screen from its fixed constraints and completing the replacement operation smoothly. This greatly saves the time and labor costs required for screen replacement, significantly improving production efficiency. At the same time, it ensures that the screen is firmly pressed by the limiting block after installation, providing excellent stability and effectively preventing loosening or displacement of the screen during operation. This ensures the accuracy and stability of the screening operation, thereby improving the screening quality of the product.

[0008] Furthermore, multiple sets of mounting columns are installed at equal intervals at both ends of the screen frame, and one end of the mounting column with the limit block is located outside the main body of the device, and the outer wall of the mounting column is provided with external threads.

[0009] By adopting the above technical solution, the limiting block can be fixed to the screen frame by rotating the mounting column.

[0010] Furthermore, the limiting blocks are symmetrically arranged at the top of the mounting column, and the limiting blocks are rectangular in shape with beveled corners.

[0011] By adopting the above technical solution, the limiting block can be more easily inserted into the installation slot and the limiting slot.

[0012] Furthermore, the worm gear is designed to correspond to the mounting block, and a threaded hole corresponding to the outer wall of the mounting column is provided at the center of the worm gear.

[0013] By adopting the above technical solution, the worm gear rotates, causing the mounting block to rotate and rise and fall, thereby fixing the screen.

[0014] Furthermore, the rotating sleeve is provided correspondingly to the mounting post, and the outer diameter of the rotating sleeve is smaller than the outer diameter of the worm gear, and the inner diameter of the rotating sleeve corresponds to the outer diameter of the mounting post.

[0015] By adopting the above technical solution, the rotating sleeve restricts the position of the worm gear without hindering the lifting and rotation of the mounting column.

[0016] Furthermore, the mounting groove is designed with an opening on the side close to the main body of the device, and the top of the mounting groove is connected to the end of the limiting groove, and the depth of the limiting groove is greater than the thickness of the limiting block.

[0017] By adopting the above technical solution, the limiting block enters the limiting groove through the installation groove to fix the screen.

[0018] Furthermore, the worm gears are symmetrically arranged inside the main body of the device, and the transmission rod is located between the two sets of worm gears, and the second bevel gear is symmetrically arranged at both ends of the transmission rod.

[0019] By adopting the above technical solution, rotating one set of worm gears can achieve the simultaneous rotation of two sets of worm gears.

[0020] In summary, the present invention has the following main advantages:

[0021] This invention, by incorporating an installation groove, a limiting groove, an installation column, a limiting block, a worm gear, a rotating sleeve, a worm, a first bevel gear, a transmission rod, a second bevel gear, and a rotating disk, makes the screen replacement process extremely convenient and efficient. Operators only need to rotate the rotating disk to cause the installation column to precisely rotate and raise the limiting block, thus quickly and easily releasing the screen from its fixed position and smoothly completing the replacement operation. This significantly saves time and labor costs associated with screen replacement, substantially improving production efficiency. Simultaneously, it ensures that the screen is firmly pressed down by the limiting block after installation, providing excellent stability and effectively preventing loosening or displacement during operation. This guarantees the accuracy and stability of the screening operation, thereby improving the screening quality of the product. Attached Figure Description

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The embodiments of this utility model will be described below based on its overall structure.

[0034] A screening device for food production, such as Figure 1 - Figure 9 As shown, the device includes a main body 1, a screen 2, and a screen frame 3. A rotating sleeve 51 is rotatably mounted inside the main body 1, and a worm gear 5 is fixedly mounted at the end of the rotating sleeve 51. A mounting post 4, threadedly connected to the worm gear 5, is rotatably mounted inside the main body 1, and a limiting block 41 is fixedly mounted at the end of the mounting post 4. The outer wall of the screen frame 3 has a mounting groove 31 and a limiting groove 32 corresponding to the limiting block 41. A worm 6, corresponding to the worm gear 5, is rotatably mounted inside the main body 1, and a first bevel gear 61 is fixedly mounted on the outer wall of the end of the worm 6. A transmission rod 7 is rotatably mounted inside the main body 1, and a second bevel gear, corresponding to the first bevel gear 61, is fixedly mounted on the outer wall of the end of the transmission rod 7. 71. A rotating disk 8 is fixedly installed at the end of the worm gear 6, making the replacement process of the screen 2 extremely convenient and efficient. The operator only needs to operate the rotating disk 8 to cause the mounting column 4 to drive the limiting block 41 to rotate and lift precisely, thereby quickly and conveniently releasing the fixed restraint of the screen 2 and successfully completing the replacement operation. This greatly saves the time and labor costs required to replace the screen 2, significantly improving production efficiency. At the same time, it ensures that the screen 2 is firmly pressed by the limiting block 41 after installation, with excellent stability, effectively preventing the screen 2 from loosening or shifting during operation, ensuring the accuracy and stability of the screening operation, and thus improving the screening quality of the product.

[0035] Please see Figure 2 - Figure 9 Multiple sets of mounting columns 4 are installed at equal intervals at both ends of the screen frame 3. One end of the mounting column 4 with the limiting block 41 is located outside the main body 1 of the device. The outer wall of the mounting column 4 is provided with external threads, so that the limiting block 41 can be fixed to the screen frame 3 by rotating the mounting column 4.

[0036] Please seeFigure 2 - Figure 9 The limiting block 41 is symmetrically arranged at the top of the mounting column 4, and the limiting block 41 is rectangular in shape. The corners of the limiting block 41 are beveled, which makes it easier for the limiting block 41 to enter the mounting groove 31 and the limiting groove 32.

[0037] Please see Figure 2 - Figure 9 The worm gear 5 is designed to correspond to the mounting block, and the center of the worm gear 5 has a threaded hole corresponding to the outer wall of the mounting column 4, so that the rotation of the worm gear 5 drives the mounting block to rotate and rise and fall, thereby fixing the screen 2.

[0038] Please see Figure 2 - Figure 9 The rotating sleeve 51 is correspondingly provided with the mounting column 4, and the outer diameter of the rotating sleeve 51 is smaller than the outer diameter of the worm gear 5, and the inner diameter of the rotating sleeve 51 corresponds to the outer diameter of the mounting column 4, so that the rotating sleeve 51 restricts the position of the worm gear 5 and does not hinder the lifting and rotation of the mounting column 4.

[0039] Please see Figure 6 - Figure 8 The mounting groove 31 is designed to be open on one side close to the main body 1 of the device, and the top of the mounting groove 31 is connected to the end of the limiting groove 32. The depth of the limiting groove 32 is greater than the thickness of the limiting block 41, so that the limiting block 41 enters the limiting groove 32 through the mounting groove 31 to fix the screen 2.

[0040] Please see Figure 2 - Figure 5 The worm gears 6 are symmetrically arranged inside the main body 1 of the device, and the transmission rod 7 is located between the two sets of worm gears 6. The second bevel gear 71 is symmetrically arranged at both ends of the transmission rod 7, so that rotating one set of worm gears 6 can realize the simultaneous rotation of the two sets of worm gears 6.

[0041] The working principle of this utility model is as follows: When changing the screen 2, the rotating disk 8 needs to be manually rotated initially. This operation will drive the worm gear 6 to start rotating. With the help of the ingenious cooperation between the first bevel gear 61 and the second bevel gear 71, the power is smoothly transmitted to the transmission rod 7, causing it to rotate. This, in turn, drives the two sets of worm gears 6 to rotate synchronously. The rotation of the worm gear 6 will drive the multiple sets of worm wheels 5 that mesh with it to start rotating. Since the inner wall of the worm wheel 5 is threaded, during its rotation, the mounting column 4 will rise relative to the threaded direction. As the mounting column 4 rises, the limiting block 41 that originally applied pressure to the screen frame 3 will gradually move away from the bottom of the limiting groove 32. When the mounting column 4 rises to a certain extent, the pressure of the limiting block 41 on the screen frame 3 is completely released. At this time, the screen frame 3 can rotate freely until the limiting block 41 rotates into the mounting groove 31, and the restriction on the screen frame 3 is completely released. Then the screen 2 can be manually removed.

[0042] After removing the old screen 2, manually place the new screen 2 into the corresponding position inside the main body 1 of the device, aligning the mounting groove 31 with the mounting block and the limiting block 41. Then, rotate the rotating disk 8 in the reverse direction. This operation will cause the worm gear 6 to drive the worm wheel 5 to rotate in the reverse direction, thereby causing the mounting column 4 to rotate in the reverse direction and descend. During this process, the limiting block 41 will gradually rotate from the mounting groove 31 to the limiting groove 32, continuing to rotate until the limiting block 41 tightly presses the screen frame 3. In this way, the screen 2 can be easily replaced, and the stability of the screen 2 after installation can be ensured. This effectively improves the efficiency and reliability of the screen 2 replacement operation, laying a good foundation for the efficient operation of the entire food production screening process.
