Description
Technical Field
The utility model relates to the field of negative pressure filling, in particular to a cut-off type negative pressure filling head.
Background
The filling modes of powdery dairy products on the market are divided into two types: screw metering and negative pressure volume filling.
In screw metering filling, the weight of the filling is controlled by controlling the number of revolutions or time of screw rotation. When the screw stops rotating, the powder material forms a bridge at the outlet and does not fall. The filling mode has high weight precision, but the screw rod and the stirring mechanism in the hopper can damage the granularity of the materials to a certain extent, so that the quality of the materials can be influenced.
In contrast, negative pressure positive displacement filling first draws air into a packaging container to form a negative pressure, and then utilizes a pressure differential to drain the material in the hopper into the container. By controlling the degree of negative pressure, the filling time and the container volume, the filling weight can be controlled. After filling, the container is restored to normal pressure, and the powder material forms a bridge at the outlet and does not fall. Because the materials in the hopper are not stirred, the granularity damage to the materials is small.
After the two filling modes are finished, powder materials are utilized to form a bridge at the outlet. According to the characteristics of different materials, the meshes with different pore sizes are selected for interception. When the fluidity of the material is higher, bridging is not easy to form, and vibration during the running of the equipment can cause the material to drop and fly upwards, which is not beneficial to the cleaning of the production environment.
