[0002] In the food production and processing industry, a variety of powdered raw materials are used when processing various types of food, such as flour, corn starch, starch, cassava flour, etc. These powdered raw materials are important components for ensuring the taste of food, and the powdered raw materials may contain different impurities, such as iron wire, sand and gravel, roots, stems and leaves, etc. In order to ensure the quality of food, the powdered raw materials must be screened. At the same time, the screening process can also screen out the condensed blocks in the powdered raw materials, which is convenient for subsequent processing; and in the prior art, a vibrating screen frame is usually used to screen powdered raw materials such as flour. During the screening process, huge noise will be generated, which has certain damage to the health of workers, and the screen frame and the collection frame used to receive the screened powdered raw materials are usually installed together, which causes the collection frame to vibrate during screening, thereby causing the collection frame to move on the ground, affecting the normal production.

[0017] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0018] like Figure 1-Figure 4 As shown, this example provides a powdered raw material screening device, including: a support frame 100, a screening component 200, and a shock absorbing component 300.

[0019] A movable collecting frame 101 is provided inside the support frame 100 for collecting powdered raw materials after screening; the screening component 200 includes a bearing frame 201 provided above the support frame 100, the bearing frame 201 is connected to a pneumatic seismic source, and the bearing frame 201 is provided with two screen frames 202 arranged at intervals in the vertical direction and movable along its length direction, which are used for screening powdered raw materials, thereby improving the screening efficiency of powdered raw materials by vibration; the shock absorbing component 300 is installed on the support frame 100, including four brackets 301 respectively installed at the four corners of the support frame 100, and two support blocks 302 movable on a horizontal plane are provided on the brackets 301 in the vertical direction, and two connecting rods 203 are provided on both sides of the bearing frame 201, and the connecting rods 203 are penetrated in the support blocks 302.

[0020] Specifically, two support plates 204 are provided on the inner walls of both sides of the carrier 201, and the screen frame 202 is located on the support plates 204. Two stoppers 205 are also penetrated on both sides of the carrier 201. The side of the stopper 205 away from the center of the carrier 201 is arc-shaped, and the other side abuts against the screen frame 202. A baffle 206 is provided at one end of the stopper 205, and a push rod 207 is provided on the baffle 206. One end of the push rod 207 is penetrated on the side frame 208, and the side frame 208 is installed on the outside of the carrier 201. A first spring 209 is also sleeved on the push rod 207. The first spring The two ends of 209 are respectively abutted against the side frame 208 and the baffle plate 206 and are always in a compressed state. When the screen frame 202 is placed from the support plate 204 into the carrier frame 201, the two side edges of the screen frame 202 will contact the arc surface of the block 205, thereby forcing the block 205 to move to the outside of the carrier frame 201, and the first spring 209 is further compressed until the screen frame 202 is completely moved into the carrier frame 201. Then, the block 205 pops out under the action of the first spring 209, thereby limiting the end of the screen frame 202 and preventing the screen frame 202 from shaking out.

[0021] Specifically, in order to prevent the upper screen frame 202 from popping out during vibration, two symmetrically arranged and inverted L-shaped plates 210 are provided on the top surface of the carrier 201 for abutting against the top surface of the screen frame 202 , thereby limiting the position of the screen frame 202 .

[0022] Specifically, in order to facilitate the support and shock absorption of the support frame 201, two limit frames 303 are provided on the bracket 301 in the vertical direction, and limit grooves 304 are provided on all four sides of the limit frames 303. Slide blocks 305 are slidably fitted in the limit grooves 304. A plurality of cross bars 306 are provided on the peripheral side of the support block 302. The cross bars 306 are inserted into the slide blocks 305. A second spring 307 is also sleeved on the cross bars 306. The two ends of the second spring 307 are respectively abutted against the support block 302 and the slide block 305, and are always in a compressed state. When the support frame 201 vibrates, the second spring 307 will be deformed. Among the second springs 307 located on the same straight line, if one of the second springs 307 is compressed, the other second spring 307 will be stretched, and the forces of the two second springs 307 are offset by each other, thereby absorbing the vibration from the vibration frame 201 and reducing noise.

[0023] Specifically, one end of the connecting rod 203 is installed on the connecting plate 211, and the connecting plate 211 is installed on the side of the supporting frame 201. A third spring 212 is also sleeved on the connecting rod 203. The two ends of the third spring 212 are respectively abutted against the connecting plate 211 and the support block 302, and are always in a compressed state. The two third springs 212 in the vertical direction are used to absorb the vibration of the supporting frame 201 in the vertical direction, thereby further reducing noise.

[0024] Since the above are only preferred embodiments of the present invention and are not intended to limit the present invention, it is obvious that those skilled in the art can make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
