Abstract
Description
Technical Field
[0001] This utility model relates to the field of pastry food processing machinery, specifically to a pastry making sieving machine. Background Technology
[0002] In pastry processing, sieving raw materials ensures a finer and more uniform texture. Ingredients such as flour, powdered sugar, and cocoa powder may become damp and clump together during storage, or become contaminated with foreign matter. Sifting ensures the ingredients are fine and uniform, preventing lumps or a coarse texture in the finished product. When powdered ingredients are sifted, air is incorporated, improving the fluffiness during subsequent mixing. For example, when making sponge cake, sifted cake flour blends more easily with the egg mixture, reducing deflation caused by stirring. In high humidity, ingredients such as flour, powdered sugar, starch, and almond flour (containing natural oils) are prone to dampness and clumping, causing particles to stick together and clog the sieve mesh. Therefore, regular cleaning of the sieve is necessary to ensure the mesh remains clear, allowing the ingredients to pass through smoothly, guaranteeing efficient and high-quality sieving, and achieving the required fineness and uniformity for the pastry ingredients.
[0003] According to the patent authorization announcement number (CN221847811U), a flour sieving device for Camellia chrysantha pastry production includes an electric push rod, sieve frame A, sieve frame B, sieve mesh A, sieve mesh B, slide rod, slide sleeve, vibration motor, servo motor, and drive plate. Cleaning the sieve mesh requires opening the box door of the frame, then opening the frame door of the sieve frame to expose the sieve mesh, and finally, the operator must go inside the sieve mesh for cleaning. The structure disclosed in this patent has defects in practical application, specifically: the sieve mesh cleaning process is cumbersome and requires a lot of time and manpower, especially in large pastry processing equipment where the sieve mesh is large and the installation position is complex, making disassembly and installation more difficult and time-consuming. Utility Model Content
[0004] The purpose of this utility model is to provide a pastry making sieving machine, which can solve the problem that the existing screen cleaning process is cumbersome and requires a lot of time and manpower.

Detailed Implementation
[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.
[0022] Example
[0023] Please refer to Figure 1 and Figure 2In some embodiments of this application, the frame 1 is mounted on a base surface and consists of four support columns, with reinforcing ribs installed between adjacent support columns. The elastic element 2 can be a spring, with four springs mounted on the four support columns, and the other ends of the four springs connected to the same screen box 4. The springs can be made of carbon steel, possessing high strength, good elasticity, and fatigue resistance, and can maintain stable elastic deformation under prolonged vibration, ensuring the vibration effect of the screen box 4. The side wall of the screen box 4 has a feed inlet, allowing raw materials to be added into the screen box 4. The overall structure of the screen box 4 is relatively enclosed; when the raw material vibrates and tumbles within the screen box 4, any tendency to fly outwards is prevented by the physical barrier of the screen box 4, thus preventing it from splashing outside the screen box 4. A screen 6 is installed inside the screen box 4, and the screen 6 has multiple screen holes 16. The raw material added to the screen box 4 falls onto the screen 6. Particles smaller than the size of the screen holes 16 can pass through the screen holes 16 and fall to the bottom of the screen box 4 for collection; particles larger than the size of the screen holes 16 are trapped on the screen 6, thus achieving preliminary separation of raw materials of different particle sizes. The discharge port on the side wall of the screen box 4 can be opened to discharge the trapped material inside the screen box 4. Two vibrating motors 3 are installed at the bottom of the screen box 4, which provide vibration sources to the screen box 4. When the two vibrating motors 3 rotate synchronously and in opposite directions, the excitation forces generated by the eccentric blocks in the two vibrating motors cancel each other out in the direction parallel to the motor shaft and are superimposed into a resultant force in the direction perpendicular to the motor shaft. Under the combined action of the excitation force and the weight of the raw material itself, the raw material is thrown up on the screen 6, thereby achieving the purpose of screening. The pressure-type drive plate 8 is installed inside the screen box 4. Multiple anti-clogging components are installed at the bottom of the pressure-type drive plate 8, and the multiple anti-clogging components correspond one-to-one with the multiple screen holes 16.
[0024] Working Principle: The sieving machine can remove lumps and foreign objects from raw materials such as flour, powdered sugar, and cocoa powder that have become damp, thus preventing granules or a rough texture in the finished product. After prolonged use, the sieve 6 may accumulate damp, lumpy flour, powdered sugar, and almond powder (containing natural oils), causing blockage of the sieve holes 16. This necessitates frequent pauses to clean the sieve 6, extending operating time. The operator can control the downward-pressing drive plate 8 to move towards the sieve 6, and multiple unblocking components will move towards the multiple sieve holes 16. After moving a preset distance, the unblocking components can pass through the multiple sieve holes 16, thereby squeezing and pushing away the lumps attached to the sieve holes 16, restoring the sieve holes to their unobstructed state and enabling them to sieve again. Then, the operator can control the downward-pressing drive plate 8 to move away from the sieve 6, and the sieving process can resume. The unclogging component can quickly locate and clean the clogged screen holes 16, greatly saving operation time and labor costs; when cleaning the screen 6, it is not necessary to disassemble the screen 6, avoiding the problem of wear or damage to the connection parts of the equipment caused by frequent disassembly and installation of the screen 6.
[0025] Please refer to Figure 1 and Figure 2 In some embodiments of this application, push rod 5 is installed at the top of screen box 4. After passing through the top of screen box 4, push rod 5 is connected to a downward-pressing drive plate 8. A first return spring 7 is sleeved on the outside of push rod 5. One end of the first return spring 7 is connected to the inner wall of screen box 4, and the other end of the first return spring 7 is connected to the outer wall of downward-pressing drive plate 8. When cleaning screen 6, the operator pushes push rod 5, push rod 5 presses down on downward-pressing drive plate 8, downward-pressing drive plate 8 moves toward screen 6, and first return spring 7 is in a stretched state. Until multiple unblocking components at the bottom of downward-pressing drive plate 8 pass through multiple screen holes 16 of screen 6, squeezing and pushing away the clumps attached to screen holes 16, the operator removes the pushing force applied to push rod 5. During the recovery deformation process, first return spring 7 can pull downward-pressing drive plate 8 upward, so that downward-pressing drive plate 8 is away from screen 6, ensuring that screening can continue in screen box 4.
[0026] Please refer to Figure 2 and Figure 3 In some embodiments of this application, the bottom end of the downward-pressing drive plate 8 is provided with multiple mounting slots 9, each corresponding to a different unblocking component. The unblocking components are mounted in the mounting slots 9 via a second return spring 10. When the downward-pressing drive plate 8 moves downward to clean the screen 6, if some unblocking components fail to accurately align with the screen holes 16 of the screen 6, the unblocking components will be subjected to a reverse force from the surface of the screen 6. This reverse force causes the second return spring 10 to compress and deform, while the unblocking components move into the mounting slots 9, thereby preventing damage to the unblocking components due to hard impact.
[0027] Please refer to Figure 2 and Figure 3In some embodiments of this application, the unblocking assembly consists of an unblocking probe 15, a base sleeve 11, and a rotating sleeve 12. The front end of the unblocking probe 15 is rounded, allowing for smoother cleaning when it contacts the screen 6 during the unblocking process, avoiding the risk of scratching or puncturing the screen 6 as with a sharp end. The outer diameter of the unblocking probe 15 is slightly smaller than the aperture of the screen hole 16, so that after the unblocking probe 15 enters the screen hole 16, it can push out all the residue inside the screen hole 16. One end of the base sleeve 11 is connected to a second return spring 10, and the other end of the base sleeve 11 is provided with a spherical cavity 13. One end of the rotating sleeve 12 has a spherical part 14 located inside the spherical cavity 13, and the other end of the rotating sleeve 12 is connected to the unblocking probe 15. The rotating sleeve 12 can rotate relative to the base sleeve 11. When the unblocking probe 15 is not aligned with the corresponding screen hole 16 during the unblocking operation, the reaction force generated by the screen 6 on the unblocking probe 15 is ultimately transferred to the second return spring 10. The second return spring 10 undergoes elastic deformation under the reaction force, and the rotating sleeve 12 rotates under the constraint of the base sleeve 11 to adjust the position of the unblocking probe 15. The elastic buffering of the second return spring 10 and the flexible rotation of the rotating sleeve 12 allow the unblocking probe 15 to adaptively adjust its position when subjected to the reaction force, avoiding damage caused by hard impacts. This also increases the probability of the unblocking probe 15 accurately aligning with the screen hole 16, improving the efficiency and reliability of the unblocking operation.
[0028] Please refer to Figures 2 to 4 In some embodiments of this application, the funnel-shaped mounting groove 9 has a gradually tapering shape, with a larger inner diameter at the opening and a smaller inner diameter towards the inside of the groove. This provides natural guidance for the unblocking probe 15, reducing the difficulty of insertion due to deviation, and allowing the unblocking probe 15 to enter the mounting groove 9 more accurately.
[0029] The auxiliary function of the rotating sleeve 12: When the unblocking probe 15 enters the mounting groove 9 under the guidance of the funnel-shaped groove, if there is a certain angular deviation, the inclined surface of the funnel-shaped groove will generate a lateral force on the unblocking probe 15, which will be transmitted to the rotating sleeve 12. The spherical part 14 at one end of the rotating sleeve 12 can be rotated and adjusted accordingly in the spherical cavity 13 of the base sleeve 11 according to this lateral force, so that the unblocking probe 15 can better adapt to the direction of the mounting groove 9, and can enter the mounting groove 9 more accurately, increasing the linkage between the components during the position adjustment process.
[0030] The coordination of the second return spring 10: When the unblocking probe 15 is obstructed from aligning with the sieve hole 16, firstly, the rotating sleeve 12 will rotate relative to the base sleeve 11 due to the force; secondly, the reaction force will be transmitted to the second return spring 10, causing the second return spring 10 to undergo elastic deformation. The funnel-shaped groove makes the force situation of the unblocking probe 15 when it enters more conducive to the coordinated function of the second return spring 10 and the rotating sleeve 12. Because the guiding effect of the funnel-shaped groove can make the force direction of the unblocking probe 15 more concentrated on the second return spring 10 and the rotating sleeve 12, the second return spring 10 can better assist the rotating sleeve 12 in adjusting the position of the unblocking probe 15 through the elastic force, achieving more efficient position adjustment and enhancing the linkage between the three.
[0031] In some embodiments of this application, the sliders at both ends of the pressure drive plate 8 are respectively installed in the linear guide rails on both sides of the screen box 4, thereby providing precise guidance for the pressure drive plate 8. The pressure drive plate 8 can move along a preset path in the screen box 4, which is beneficial to improving the accuracy and stability of the cooperation with the screen 6, and improving the cleaning efficiency and quality of the screen 6.
[0032] In summary, the embodiments of this utility model provide a pastry making sieving machine. The operator can control the downward-pressing drive plate 8 to move towards the screen 6, and multiple unblocking components to move towards multiple screen holes 16 of the screen 6. After moving a preset distance, the unblocking components can pass through the multiple screen holes 16, thereby squeezing and pushing away the clumps attached to the screen holes 16, restoring the screen holes 16 to their unobstructed state and enabling them to sieve again. Then, the downward-pressing drive plate 8 can be moved away from the screen 6, and sieving can be performed again. The unblocking components can quickly locate and clean the clogged screen holes 16, greatly saving operating time and labor costs. When cleaning the screen 6, it is not necessary to disassemble the screen 6, avoiding the problem of wear or damage to the connecting parts of the equipment caused by frequent disassembly and installation of the screen 6.
