Technical Field

[0001] The present application relates to the technical field of screening machines, and in particular to a screening device for producing maltoheptaose. Background Art

[0002] Maltoheptaose is a sugar molecule composed of seven glucose molecules, commonly found in maltose and other plant sources. It is an oligosaccharide, a type of polysaccharide, with specific functional properties, such as providing energy and improving intestinal health. In the food industry, maltoheptaose can be used as a sweetener, stabilizer or food additive to improve the taste and shelf life of food.

[0003] At present, when maltoheptaose is manufactured, the raw materials need to be screened. The raw materials generally need to be dried and crushed before being screened. However, when the existing screening equipment is used for feeding, the raw materials are directly put into the screening box for screening, which will cause the raw materials to be screened slowly due to accumulation. Therefore, a screening device for maltoheptaose production is designed to solve the above-mentioned problems. Utility Model Content

[0021] The following is combined with Figure 1-4 This application is described in further detail.

[0022] The present application embodiment discloses a screening device for producing maltoheptaose. Figure 1-4 A screening device for producing maltoheptaose comprises a screening box 1, a screening net 2 is fixedly connected to the screening box 1, and a screening net 2 is fixedly connected to the screening box 1. Figure 2As shown, the lower end of the screening box 1 is fixedly connected to the support platform 16, the upper end of the screening box 1 is fixedly connected to the feed hopper 3, the feed frame 4 is slidably connected inside the feed hopper 3, one side of the feed frame 4 is fixedly connected to the mounting plate 41, the middle part of the mounting plate 41 is threadedly connected to the screw rod 7, the rear part of the screw rod 7 is rotatably connected to the inner wall of the feed hopper 3, the front part of the screw rod 7 passes through the inner wall of the feed hopper 3 and is fixedly connected to the servo motor 8, and the servo motor 8 is fixedly connected to the side wall of the feed hopper 3;

[0023] The servo motor 8 can be used to drive the screw rod 7 to rotate, so that the screw rod 7 drives the mounting plate 41 to move, and the mounting plate 41 drives the feeding frame 4 to move horizontally in the feed hopper 3. When the raw materials are unloaded and transported into the screening box 1, the continuously moving feeding frame 4 drives the raw materials to be evenly scattered into the screening box 1, thereby avoiding the accumulation of raw materials during screening, resulting in slow screening efficiency.

[0024] By adopting the above technical solution, when the feeding frame 4 moving in the front-back direction continuously and evenly transports the raw materials, in order to further assist the raw materials to descend into the screening box 1, a fixed plate 9 is fixedly connected to the lower end of one side of the feeding frame 4, and both sides of the middle section of the fixed plate 9 are rotatably connected to the rotating rod 10, and one side of the rotating rod 10 is fixedly connected to the threaded rod 13, and the threaded rod 13 is threadedly connected to the moving ring 14, and the moving ring 14 is fixedly connected to the push plate 15 on the side close to each other;

[0025] When the threaded rod 13 rotates, the threaded rod 13 drives the moving ring 14 to move, and the moving ring 14 drives the pushing plate 15 to move. When the feeding frame 4 is transported and originally descends, the pushing plate 15 moves and hits the raw materials in the unloading process, so that the raw materials are broken up, and then they are screened in the screening net 2 that falls into the screening box 1.

[0026] By adopting the above technical solution, a feeding port is provided in the middle of the lower end of the feeding frame 4, and the feeding port is located above the pushing plate 15, so that the pushing plate 15 can accurately break up the fallen raw materials.

[0027] By adopting the above technical solution, in order to facilitate the continuous rotation of the threaded rod 13, the gear 11 is fixedly connected to the side of the rotating rod 10 away from the threaded rod 13, the lower end of the gear 11 is meshed with the gear plate 12, and the gear plate 12 is fixedly connected to the side wall of the feed hopper 3. When the feeding frame 4 moves, it drives the fixed plate 9 to move, and the fixed plate 9 drives the gear 11 to move. The gear 11 moves to mesh with the gear plate 12. Therefore, when the gear 11 moves, it will also rotate around itself as the center and drive the rotating rod 10 on one side to rotate. The rotating rod 10 drives the threaded rod 13 to rotate, so that the moving ring 14 and the push plate 15 can continue to move and break up the falling raw materials.

[0028] By adopting the above technical solution, in order to facilitate the feeding of raw materials into the feeding frame 4, a soft frame 5 is fixedly connected to the upper end of the feeding frame 4, one side of the soft frame 5 is fixedly connected to a support rod 6, and the support rod 6 is fixedly connected to the side wall of the feed hopper 3 away from the soft frame 5.

[0029] The implementation principle of a screening device for producing maltoheptaose in an embodiment of the present application is as follows: the raw material is put into the feeding frame 4 from the soft frame 5, and then the servo motor 8 is started. The servo motor 8 drives the screw rod 7 to rotate, so that the screw rod 7 drives the mounting plate 41 to move, and the mounting plate 41 drives the feeding frame 4 to move horizontally in the feed hopper 3. When the raw material is unloaded and transported into the screening box 1, the feeding frame 4 that has been moving drives the raw material to be evenly scattered into the screening box 1, thereby avoiding the accumulation of raw materials during screening. While the feeding frame 4 moves, the feeding frame 4 will also drive the fixed plate 9 to move, and the fixed plate 9 will drive the gear 11 to move. The gear 11 moves to engage with the gear plate 12. Therefore, when the gear 11 moves, it will also rotate around itself as the center and drive the rotating rod 10 on one side to rotate. The rotating rod 10 drives the threaded rod 13 to rotate, so that the moving ring 14 and the pushing plate 15 can move continuously and break up the falling raw materials, further preventing the accumulation caused by the direct falling of the raw materials.
