Description

Technical Field

[0001] The utility model relates to the technical field of food processing, in particular to a raw material vibrating screen for food processing. Background Art

[0002] The rough processing in the food raw material processing flow includes steps such as cleaning, screening and impurity removal, and drying. Its purpose is to process the food raw materials into a clean state that is convenient for subsequent fine processing. During the screening and impurity removal process, a vibrating screen can be used to vibrate and screen the food raw materials.

[0003] However, when using a vibrating screen to screen materials, the mixture of materials and impurities will move from the inside to the outside of the vibrating screen during the vibration process. The screened impurities remain on the screen and move to the outermost side of the screen before being discharged from the output port. Therefore, during the impurity screening process of food raw materials, if a large amount of food raw materials are directly poured onto the vibrating screen at one time, the materials on the outside due to material accumulation will move to the outside of the screen during the vibration process and be quickly discharged, resulting in the food raw materials being mixed with impurities and discharged before they have time to pass through the screen. In order to address this problem, a food processing raw material vibrating screen machine is proposed to solve this problem. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 A raw material vibration screen for food processing includes a vibration screen assembly 1, a base 2 and a hopper 3. The base 2 supports the vibration screen assembly 1. The vibration screen assembly 1 mainly consists of a screen and a vibration motor and other components. For details, please refer to the prior art. The prior art products are not described in detail in this solution.

[0022] A support frame 4 connected to the hopper 3 is installed on the base 2, and a groove is provided on the side wall of the support frame 4. A rotating shaft 16 is provided in the groove through the driving motor 15 to rotate, and a turntable 6 is provided on the support frame 4 through the support plate 5 to rotate, and an opening corresponding to the turntable 6 is provided at the position of the drop pipe of the hopper 3, and a drop port 7 is provided on the turntable 6, and the turntable 6 is connected to the rotating shaft 16 through a rotating mechanism, and a fixed block 13 is fixedly installed on the side wall of the support frame 4, and a slide rod 12 is slidably penetrated through the fixed block 13 through an elastic mechanism, and a rack 10 is installed on the end of the slide rod 12, and the rack 10 is connected to the rotating shaft 16 through a transmission mechanism, and an impact block 11 corresponding to the hopper 3 is installed on the end of the rack 10.

[0023] The rotating mechanism includes a first pulley 8 rotatably mounted on the upper end surface of the support plate 5 and fixedly connected to the turntable 6, a second pulley is fixedly mounted on the outer wall of the rotating shaft 16, the first pulley 8 and the second pulley are connected by a belt, and the first pulley 8 cooperates with the second pulley and the belt to realize power transmission of the drive motor 15. After the drive motor 15 is started, the turntable 6 can rotate synchronously.

[0024] The elasticity includes a spring 14 sleeved on the outside of the slide rod 12, and an anti-slip block is fixedly installed on the end of the slide rod 12. The two ends of the spring 14 are elastically connected to the outer wall of the fixed block 13 and the outer wall of the anti-slip block respectively. The elastic potential energy provided by the spring 14 can drive the impact block 11 and other components to move and reset and impact the hopper 3 when the rack 10 and the slide rod 12 are driven to move by the incomplete gear 9 and the incomplete gear 9 loses engagement with the rack 10.

[0025] The transmission mechanism includes an incomplete gear 9 which is rotatably mounted on the upper end surface of the support frame 4 and fixedly connected to the rotating shaft 16. The incomplete gear 9 cooperates with the rack 10. By setting the incomplete gear 9, when the part without teeth corresponds to the rack 10, the rack 10 loses the meshing drive. Conversely, when the part with teeth of the incomplete gear 9 corresponds to the rack 10, the rack 10 can be driven to move horizontally by rotating the incomplete gear 9.

[0026] The hopper 3 and the impact block 11 are both made of metal. The metal material design ensures the service life. The vertical cross-section of the hopper 3 is conical in design, and this shape design makes it easier for materials to fall into the vibrating screen assembly 1.

[0027] The surface of the base 2 that contacts the ground is provided with a rubber pad, and the surface of the rubber pad that contacts the ground is provided with anti-skid patterns. When the device as a whole is working, vibration will be generated, and the rubber pad is used to reduce vibration and noise. The anti-skid patterns ensure anti-skid properties and thus ensure the stability of the device as a whole.

[0028] When the utility model is used, the material is placed in the hopper 3, the vibrating screen assembly 1 is started, and the material falls into it to complete the screening operation. In this process, the driving motor 15 is in the starting state and the speed is uniform and slow, which drives the rotating shaft 16 to rotate. The rotation of the rotating shaft 16 drives the second pulley and the incomplete gear 9 to rotate synchronously. The second pulley cooperates with the belt to drive the first pulley 8 to rotate. The rotation of the first pulley 8 can drive the turntable 6 to rotate relative to the hopper 3. When the drop opening 7 on it corresponds to the discharge pipe part of the hopper 3, the drop operation is realized, otherwise it will not fall. The material can be prevented from being accumulated too much in the vibration screen assembly 1 and affecting the screening effect. Secondly, the rotation of the incomplete gear 9 can drive the impact block 11 to move and away from the hopper 3 with the help of the rack 10. In the away state, the spring 14 is in a compressed state. When the part without teeth on the incomplete gear 9 corresponds to the rack 10, the rack 10 loses the meshing restraint. At this time, the spring 14 is reset and drives the rack 10 and the impact block 11 to move and reset with the help of the slide bar 12, and the impact hopper 3 generates vibration. The vibration is transmitted to the material in the hopper 3 to ensure the smoothness of its falling.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
