[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1 to 4This utility model provides a technical solution: a raw material screening screen for food processing, including a screen assembly 1, which is composed of an upper screen frame 2, a lower screen frame 3, and a screen plate 4;
[0023] The four bottom corners of the lower screen frame 3 are connected to the spring 6. With the help of the spring 6, the lower screen frame 3 is installed in the inner cavity of the side supports 5 at both ends. The upper screen frame 2 is mounted on the lower screen frame 3. The upper screen frame 2, the lower screen frame 3 and the spring 6 are inserted into the side supports 5 on both sides in the vertical direction through the pin 51, so as to achieve a stable connection between the three and the side supports 5.
[0024] The upper screen frame 2 is securely connected to the lower screen frame 3 via the fixing rod 22.
[0025] In use, first install the spring 6 at the four bottom corners of the lower screen frame 3. Then, place the lower screen frame 3 with the spring 6 inside the inner cavity of the side supports 5 at both ends. Next, place the upper screen frame 2 on top of the lower screen frame 3. Use the pin 51 to insert vertically into the side supports 5 on both sides to achieve a stable connection between the upper screen frame 2, the lower screen frame 3, the spring 6, and the side supports 5. At the same time, use the fixing rod 22 to firmly connect the upper screen frame 2 and the lower screen frame 3. Pour the food raw materials to be screened into the upper screen frame 2. Since the screen plate 4 is installed on the upper screen frame 2 and the lower screen frame 3, the upper screen frame 2 and the lower screen frame 3 will be stable. Between the screen frames 3, the raw material falls onto the screen plate 4. An initial external force is applied to the screen assembly 1 by manual pushing. At this time, the lower screen frame 3, due to its connection with the spring 6, will vibrate after being subjected to the external force. The elasticity of the spring 6 enables the lower screen frame 3 to vibrate up and down continuously. The spring 6 is made of spring steel, and its good elasticity ensures that the screen works stably during long-term vibration screening. During the vibration, the raw material on the screen plate 4 will jump and move on the screen plate 4. Raw material particles smaller than the mesh of the screen plate 4 will fall through the screen holes, achieving screening and separation.
[0026] Please see Figures 1 to 4 Both ends of the spring 6 are connected to the positioning block 61. The lower screen frame 3 is connected to the upper screen frame 2 and the side support 5 through the positioning blocks 61 at the upper and lower ends of the spring 6. In use, the spring 6 and the screen frame can be quickly connected and separated through the positioning block 61, making the replacement, maintenance or repair of the spring 6 and the screen frame more convenient.
[0027] Please see Figures 1 to 4 The connection part of the fixing rod 22 adopts a threaded structure design. The upper screen frame 2 is installed in the screw cavity 31 of the lower screen frame 3 by means of a screw connection through the fixing rod 22. In use, the upper and lower screen frames are tightly fixed by the screw connection to ensure that there is no relative displacement between the screen frames under high frequency vibration conditions. At the same time, it facilitates the subsequent disassembly work.
[0028] Please see Figures 1 to 4 The upper screen frame 2 and the lower screen frame 3 are provided with slots 41 inside, and the screen plate 4 is installed on the slots 41 inside the upper screen frame 2 and the lower screen frame 3 respectively in a snap-fit manner.
[0029] The slot 41 facilitates the subsequent disassembly and cleaning of the sieve plate 4.
[0030] Please see Figures 1 to 4 The screen plates 4 in the upper screen frame 2 and the lower screen frame 3 have different diameters. The diameter of the screen plate 4 in the upper screen frame 2 is larger than that in the lower screen frame 3. This is to achieve the classification and screening of raw materials of different particle sizes.
[0031] Please see Figures 1 to 4 A detachable auxiliary grip 21 is installed above the upper screen frame 2, which allows the staff to apply external force to the upper screen frame 2.
[0032] Please see Figures 1 to 4 The bottom of the side support 5 has a placement area 52, which can be used to place the collection box.
[0033] In use, the food raw materials to be screened are poured into the upper screen frame 2, and the raw materials will fall onto the screen plate 4. The operator applies an initial external force to the upper screen frame 2 by manually pushing it through the auxiliary grip 21. The lower screen frame 3, which is connected to the spring 6, vibrates after being subjected to the external force. Under the elastic action of the spring 6, the lower screen frame 3 continues to vibrate up and down, driving the entire screen assembly 1 to vibrate. During the vibration, the raw materials on the screen plate 4 jump. Raw material particles smaller than the mesh of the screen plate 4 in the upper screen frame 2 fall through the screen plate 4 first and continue to fall onto the screen plate 4 in the lower screen frame 3. Raw material particles smaller than the mesh of the screen plate 4 in the lower screen frame 3 fall through the screen plate 4 into the collection frame below, thus realizing the grading and screening of raw materials of different particle sizes.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
