Description

Technical Field

[0001] This utility model relates to the field of material handling equipment technology, and in particular to automated equipment for material feeding. Background Technology

[0002] In modern industrial production, automated feeding equipment is widely used in various fields such as chemical, food, and pharmaceutical industries to reliably transport bulk materials such as powders and granules from storage units to subsequent process equipment such as reaction vessels and mixers. The core of these automated devices typically includes silos for temporary material storage and conveying mechanisms.

[0003] However, existing automated feeding equipment often faces significant problems when handling materials with poor flowability, easy moisture absorption and clumping, or easy adhesion. When such materials are compacted in the silo due to gravity or environmental factors, they are prone to forming stable arch bridges near the conical outlet of the silo, or the material may adhere to the inner wall of the silo, preventing it from falling smoothly and causing blockages.

[0004] Once a blockage occurs, the entire automated feeding process will be interrupted, severely impacting production continuity and efficiency. Furthermore, untimely or uneven feeding may lead to fluctuations in final product quality. Currently, some equipment relies on external vibrators to assist feeding, but for highly viscous or firmly clumped materials, the vibration effect is limited and may even exacerbate compaction. Relying on manual intervention through periodic tapping or poking completely contradicts the original intention of automated production, creating safety hazards and additional labor costs.

[0005] Therefore, this utility model proposes an automated device for material feeding to address the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides an automated feeding device for materials, which aims to improve the problems in the prior art where materials are easily blocked in the silo, resulting in poor feeding, and the feeding amount is difficult to control accurately.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1-5This utility model provides an embodiment of an automated material feeding device, including a workbench 2 and a feeding machine body 1 installed on the workbench 2. A hopper 4 is fixed inside the feeding machine body 1. The hopper 4 has an inverted conical structure, and a first conveying pipe 7 is connected to the lower end of the hopper 4. A door 3 is rotatably connected to the side wall of the feeding machine body 1. The device also includes an anti-clogging component 5, which includes a fixed box 506, a placement shell 502, a first motor 501, a rotating shaft 503, a gear 504, a gear ring 505, a rotating ring 507, and a scraper 508. Specifically, the fixed box 506 is fixed to the inner wall of the hopper 4, and the placement shell 502 is fixed to the side of the fixed box 506. The device includes a wall, a first motor 501 fixed on a housing 502, a rotating shaft 503 with one end fixedly connected to the output end of the first motor 501 and rotatably connected to a fixed box 506, a gear 504 fixedly connected to the other end of the rotating shaft 503, a gear ring 505 rotatably disposed inside the fixed box 506 and meshing with the gear 504. More specifically, the gear 504 meshes with the inner ring teeth of the gear ring 505, a rotating ring 507 fixedly connected to the gear ring 505, and a scraper 508 fixedly connected to the rotating ring 507 and extending into the hopper 4. The device also includes a dust removal fan 6, whose air inlet is connected to the upper space of the hopper 4 through a dedicated air duct.

[0028] The feeding assembly 8 includes a dome valve 805 and an electric push rod 802 for driving the dome valve 805 to deflect. The feeding assembly 8 also includes a support plate 801, a rotating rod 803, and a rotating shaft 804. The support plate 801 is fixedly connected to the outer wall of the first feeding pipe 7. The electric push rod 802 is fixed to the support plate 801. One end of the rotating rod 803 is rotatably connected to the push rod end of the electric push rod 802. The rotating shaft 804 is fixedly connected to the other end of the rotating rod 803 and rotatably penetrates the pipe wall of the first feeding pipe 7. The dome valve 805 is fixedly connected to the rotating shaft 804 that extends into the first conveying pipe 7. In the assembled state, the linear motion of the electric push rod 802 is transmitted through the rotating rod 803 and the rotating shaft 804, and finally converted into the deflection motion of the dome valve 805. This can accurately convert the linear motion of the electric push rod 802 into the angular displacement of the dome valve 805. By changing the deflection angle of the dome valve 805, the flow cross-sectional area of ​​the first conveying pipe 7 can be changed, thereby achieving precise control of the material flow rate.

[0029] To transport materials from the equipment, the equipment also includes a second conveying pipe 10, a second motor 9, and an auger 11. The second conveying pipe 10 is connected to the lower outlet of the first conveying pipe 7. The auger 11 is rotatably installed inside the second conveying pipe 10. The second motor 9 is fixed to the top of the second conveying pipe 10 and is connected to the auger 11 for transmission. The gear 504 meshes with the inner ring teeth of the gear ring 505, making the transmission more stable and compact. The side wall of the feeding machine body 1 is rotatably connected to a box door 3. In order to keep the working environment clean, the equipment also includes a dust removal fan 6. The air inlet of the dust removal fan 6 is connected to the upper space of the hopper 4 through a dedicated air duct. The hopper 4 has an inverted cone-shaped structure, which helps the material to naturally converge towards the central outlet under the action of gravity.

[0030] Working principle: When feeding is required, the material is added into the hopper 4 by opening the box door 3 on the feeding machine body 1. At the same time, the dust removal fan 6 is started to suck away the dust generated during feeding through the air duct. When the material in the hopper 4 accumulates or clumps, the anti-blocking component 5 is activated. The first motor 501 drives the rotating shaft 503 to rotate. The rotating shaft 503 drives the gear 504 to rotate. Since the gear 504 is meshed with the gear ring 505, the rotation of the gear 504 will drive the gear ring 505 to rotate inside the fixed box 506. The rotating ring 507 fixed on the gear ring 505 will rotate accordingly, and finally drive the scraper 508 to make a circular motion in the hopper 4 to break up the accumulated material and ensure that the material can flow smoothly downward.

[0031] The dispersed material falls towards the inlet of the first conveying pipe 7 under the action of gravity. At this time, the feeding assembly 8 is activated to control the feeding amount. The push rod end of the electric push rod 802 extends or retracts, causing the rotating rod 803 connected to it to deflect. The rotating shaft 804 fixed to the rotating rod 803 rotates accordingly. Since the dome valve 805 is fixed on the rotating shaft 804, the rotation of the rotating shaft 804 causes the dome valve 805 to deflect at a corresponding angle inside the first conveying pipe 7, thereby changing the flow cross-sectional area of ​​the first conveying pipe 7 and realizing precise control of the material falling flow rate. After the material with controlled flow rate enters the second conveying pipe 10 through the first conveying pipe 7, the second motor 9 is activated. The second motor 9 drives the auger 11 set inside the second conveying pipe 10 to rotate. The rotating blades of the auger 11 smoothly convey the material forward along the axial direction and finally deliver it to the designated equipment to complete the feeding.
