Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and more specifically, to a dustproof feeding device. Background Technology

[0002] Wheat flour is the raw material for spicy snack strips. During the processing of wheat flour, the unexpanded raw flour, if not properly controlled, can cause dust to settle on the already expanded dough, leading to issues such as raw material adhesion and excessive bacterial counts in the product. To address this, manufacturers typically use powerful exhaust systems to minimize dust settling. However, in reality, problems remain with incomplete dust removal or inherent defects in these systems, making it difficult to effectively control substandard products. Therefore, a dust control device for material feeding is needed to solve this problem. Utility Model Content

[0003] The purpose of this invention is to provide a dustproof feeding device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a dust-proof feeding device, including a support leg located at the bottom of the entire device, a support frame fixedly installed at the upper end of the support leg, symmetrically arranged extruder hoppers installed within the support frame, a feeding pipe connected to the top of the extruder hopper, the feeding pipe penetrating the support frame and connected to a support plate, a grinding box installed on the support plate, a second drive motor installed on the grinding box, an extruder powder hopper connected to one side of the grinding box, a powder transfer chamber provided at the upper end of the extruder powder hopper, a bidirectional spiral powder feeder installed within the powder transfer chamber, a sliding frame installed on the powder transfer chamber, and a powder transport trolley sliding on the sliding frame.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] (1) This utility model is a material feeding dust prevention device. The material feeding dust prevention device in this device increases the size of the transfer bin. When the bin on the powder transport hopper is flipped, the bin extends into the surrounding baffles of the powder transfer bin to prevent the raw material from falling directly. It can intuitively show that the powder no longer falls on the extruder table.

[0013] (2) This utility model is a material feeding dust prevention device.

[0020] The utility model will now be further described with reference to the accompanying drawings and specific embodiments:

[0021] Example 1

[0022] refer to Figures 1 to 2 Example 1 describes a device including a support leg 1 located at the bottom of the entire device. A support frame 2 is fixedly installed on the upper end of the support leg 1. Symmetrically arranged extruder hoppers 4 are installed inside the support frame 2. A discharge pipe 7 is connected to the top of the extruder hopper 4. The discharge pipe 7 passes through the support frame 2 and is connected to a support plate 8. A grinding box 22 is installed on the support plate 8. A second drive motor 10 is installed on the grinding box 22. An extruder powder hopper 23 is connected to one side of the grinding box 22. A powder transfer chamber 12 is provided at the upper end of the powder transfer chamber 23. A bidirectional spiral powder feeder 11 is installed inside the powder transfer chamber 12. A sliding frame 15 is installed on the powder transfer chamber 12. A powder transport trolley 14 slides on the sliding frame 15. A controller 6 is fixedly installed on the support frame 2. The controller 6 controls a first drive motor 9, a second drive motor 10, and a third drive motor 18. A heat dissipation hole 3 is opened on the side of the support frame 2. An opening 5 with a diameter larger than the discharge pipe 7 is opened at the upper end of the support frame 2.

[0023] In this embodiment, the grinding roller is driven by the second drive assembly in the grinding box 22 to achieve grinding, and finally enters the extruder hopper 4 through the feeding pipe 7. The speed of the bidirectional spiral powder feeder 11 can be controlled by controlling the speed of the first drive motor 9 to achieve the spiral feeding speed and powder feeding amount.

[0024] Example 2

[0025] refer to Figures 2 to 3 Example 2 is described below. This embodiment further describes Example 1. It includes a bidirectional spiral powder feeder 11 installed at the output end of the first drive motor 9. The openings on both sides of the bottom end of the powder transfer chamber 12 are connected to the powder chamber 23 of the extruder. Baffles 13 are fixedly installed on both sides of the powder transfer chamber 12. The baffles 13 are installed on the side ends of the sliding frame 15. The powder transport hopper 14 has a slot 16. A hopper 17 for placing raw powder is installed at the slot 16. The hopper 17 is connected to the inner walls on both sides of the slot 16 through an output shaft 19. The output end is fixedly installed at the output end of the third drive motor 18.

[0026] In this embodiment, the feeding transfer bin 12 is driven by the third drive motor 18 to rotate the output shaft 19 of the bucket 17 to achieve feeding. The bucket 17 extends into the surrounding baffles 13 of the feeding transfer bin 12 to prevent raw materials from falling directly. This can visually show that the powder is no longer falling onto the extruder table.

[0027] In practical applications, this device slides the raw powder to be fed onto the sliding frame 15 via the powder conveying trolley 14. When it slides onto the powder transfer bin 12, the third drive motor 18 drives the output shaft 19 to rotate the bin 17, thus discharging the raw powder. The dust prevention device is designed to enlarge the transfer bin. When the bin 17 on the powder conveying trolley 14 rotates, the bin 17 extends into the surrounding baffles 13 of the powder transfer bin 12, preventing the raw powder from spilling directly. This clearly demonstrates that the powder no longer spills onto the extruder table. The raw powder entering the powder transfer bin 12 is controlled bidirectionally by the first drive component. The rotation of the spiral feeder 11 allows raw powder to enter the puffing machine powder hoppers 23 at both bottom ends. The raw powder in the puffing machine powder hoppers 23 then enters the grinding box 22 and is ground by the grinding roller driven by the second drive assembly. Finally, it enters the puffing machine hopper 4 through the feeding pipe 7. The speed of the bidirectional spiral feeder 11 can be controlled by controlling the speed of the first drive motor 9 to achieve the spiral feeding speed and powder feeding amount. The raw material no longer spills out of the puffing machine powder hoppers 23, and the feeding pipe 7 extends into the puffing machine hopper 4 to achieve feeding. No raw powder is seen falling during the entire process, ensuring the practicality of the device.
