Description

Technical Field

[0001] The utility model relates to the technical field of feeding devices, in particular to a feeding device with good sealing performance. Background Art

[0002] A feeding device with good sealing performance is a vacuum feeding device, which is a dust-free closed pipeline conveying equipment that uses vacuum suction to convey granular and powdered materials. It uses the air pressure difference between the vacuum and the ambient space to form gas flow in the pipeline, drive the movement of powdered materials, and thus complete the transportation of powders. It is usually used in industrial production environments that need to prevent dust leakage, keep materials pure, or handle volatile and toxic substances. The device often combines advanced sealing technology and materials to ensure a high degree of sealing effect during the feeding process to meet the specific industry's requirements for efficient, safe, and environmentally friendly production.

[0003] When the feeding device is in use nowadays, the conveyed material needs to be added and placed in its dedicated hopper, but the hoppers used in traditional feeding devices are mostly wide at the top and narrow at the bottom. As the feeding device absorbs the material in the hopper, some of the material is easy to hang on the wall. The wall hanging phenomenon may cause the material in the hopper to not be effectively and completely absorbed, thereby reducing the capacity of each feeding, increasing the feeding cycle, reducing production efficiency, and may affect the feeding accuracy of the feeding device, thereby affecting the proportion of ingredients or the consistency of product quality in the subsequent processing process.
