It is widely used in the food industry, such as baking, confectionery making, and pasta processing, and helps to improve product quality and production efficiency.
[0004] Existing powdering devices installed on food conveyor belts for sprinkling powder onto the conveyed food have drawbacks. If the powder adheres to the inner wall of the powder bin during the sprinkling process, it is difficult to clean over a long period of time, and the adhered part may deteriorate, affecting food safety. Furthermore, if the sprinkling is inaccurate, it will affect the quality of the food. Therefore, a powdering device for food processing is proposed to address the above problems.

[0027] Please see Figure 1-5 This utility model provides a technical solution:
[0028] A powder-sprinkling device for food processing includes a connecting frame 1, a material box 2, and a feeding roller 8. The material box 2 is welded and fixed to the upper end of the connecting frame 1. The feeding roller 8 for feeding is rotatably connected to the bottom of the material box 2. Both ends of the material box 2 are fixedly connected to connecting shafts 9. The top end of one end of the connecting shaft 9 is fixedly connected to the main shaft of a drive motor 4. A blocking mechanism 6 is fixedly connected to the outside of the connecting shaft 9. The bottom end of the drive motor 4 is fixedly connected to the connecting frame 1 through a motor fixing plate 5. A striking mechanism 7 is installed on the upper end of the blocking mechanism 6. A laser is fixedly connected to the outside of the material box 2. The rangefinder 3; the blocking mechanism 6 includes a circular plate 61, with a first hemispherical block 62 distributed in a ring on one side of the circular plate 61; the striking mechanism 7 includes a rotating rod 71, with a column rod 75 fixedly connected to the bottom end of the rotating rod 71, a limit hole 76 opened in the middle of the rotating rod 71, and a rotating shaft 78 rotatably connected to the inner side of the limit hole 76 through a spring 77 and a bearing 79, with a fixing bracket 74 fixedly connected to both ends of the rotating shaft 78, a fixing block 72 fixedly connected to the top end of the rotating rod 71, and a second hemispherical block 73 fixedly connected to one side of the fixing block 72.
[0029] As a further implementation of this solution, there are two connecting frames 1, which are distributed on both sides of the material box 2 and are parallel to each other. With the above arrangement, it is easy to connect the whole device stably to the conveyor belt support.
[0030] As a further implementation of this solution, the circular plate 61 is on the same axis as the main shaft of the drive motor 4, the feeding roller 8, and the connecting shaft 9. The first hemispherical block 62 at the uppermost end of the circular plate 61 and the column rod 75 are set on the same horizontal plane. Through the above settings, the stability of the circular plate 61 during rotation can be guaranteed.
[0031] As a further implementation of this solution, there are two striking mechanisms 7, which correspond one-to-one with the blocking mechanism 6. The striking mechanisms 7 are set inside the connecting frame 1. By setting two striking mechanisms 7, both sides of the material box 2 can be struck at the same time, which has a better effect.
[0032] As a further implementation of this solution, the included angle between the rotating rod 71 and the fixed block 72 is 90°, and several second hemisphere blocks 73 are provided. The second hemisphere blocks 73 are located on the side of the fixed block 72 close to the material box 2. With the above arrangement, the material box 2 can be stably struck.
[0033] As a further implementation of this solution, each of the striking mechanisms 7 has two fixed frames 74 inside, and the included angle between the fixed frame 74 and the rotating shaft 78 is 90°. The fixed frame 74 is welded to the material box 2. Through the above arrangement, the stability of the striking mechanism 7 during the striking process can be further improved.
[0034] As a further implementation of this solution, two spring springs 77 are provided on the outer side of any rotating shaft 78. The spring springs 77 are located on both sides of the bearing 79. The rotating shaft 78 and the limiting hole 76 are on the same axis. The included angle between the rotating shaft 78 and the rotating rod 71 is 90°. Through the above arrangement, the stability of the rotating shaft rod 71 during rotation can be effectively improved.
[0035] Work process: The equipment is powered by an external power source during operation. In use, the entire device is first installed on the upper end of the conveyor belt frame used for conveying food through the connecting frame 1. After installation, food powder is added to the material box 2. When the conveyor belt conveys food past the lower end of the material box 2, the laser rangefinder 3 monitors the passage of the food and then controls the drive motor 4 to rotate so that when the food passes the lower end of the material box 2, the drive motor 4 drives the feeding roller 8 to rotate, so as to sprinkle the food powder onto the food.
[0036] During this process, when the feeding roller 8 rotates, the connecting shaft 9 drives the circular plate 61 to rotate. When the first hemispherical block 62 fixed on the circular plate 61 contacts the column rod 75, the rotating rod 71 and the side of the material box 2 remain horizontal. When the first hemispherical block 62 and the column rod 75 are misaligned, the rotating rod 71 rotates under the drive of the spring spring 77. At this time, the second hemispherical block 73 fixedly connected to the top fixing block 72 of the rotating rod 71 will strike the material box 2, which can prevent the food powder inside the material box 2 from adhering to the inner wall of the material box 2. At the same time, it can improve the compactness of the food powder entering the feeding groove inside the feeding roller 8, which can effectively prevent the food powder from entering the feeding groove inside the feeding roller 8 from being too loose, resulting in less food being sprinkled, thus effectively improving the quality of the food.
[0037] 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.
