Dust collecting mechanism for screw filling machine

Abstract

The invention discloses a dust collecting mechanism for a screw filling machine. The dust collecting mechanism for the screw filling machine comprises a dust collecting ring and a draught fan. The dust collecting mechanism for the screw filling machine is characterized in that the dust collecting ring is of an annular structure which can be sleeved on a circular filling mouth of the filling machine, a groove allowing dust to flow is formed between the external diameter and the internal diameter of the annular structure, a first small hole penetrating through the external diameter is formed in the external diameter, the first small hole is connected with the draught fan through a flexible pipe, and the internal diameter is provided with at least two second small holes penetrating through the internal diameter to be connected with the groove. The dust collecting mechanism for the screw filling machine can form directional absorption force to absorb splashing powder materials, the scattered small holes can enable the large absorption force of the draught fan to be scattered into some small even absorption force, and therefore only splashing powder materials in the filling mouth are absorbed, powder materials which are filled in an iron pot cannot be influenced, filling precision is not influenced, and dust collecting effects are good.

Description

technical field [0001] The invention belongs to the technical field of milk powder packaging equipment, and in particular relates to a dust collecting mechanism for a screw filling machine that prevents powder from splashing around during milk powder filling. Background technique [0002] Milk powder is generally packed in iron cans with good sealing performance. However, during the filling process of milk powder, since milk powder is a fine particle, it is easy to splash everywhere, causing pollution to the environment and equipment. The dust collection equipment in the prior art is covered on the filling nozzle of the filling machine through a circular cover. There is suction from the extension in the cover, which can suck away the powder splashed everywhere. However, due to the large space in the cover, the suction of the fan It is also large, and it is easy to suck away the powder that has been filled into the iron can, resulting in a decrease in filling accuracy.

[0002] Milk powder is generally packed in iron cans with good sealing performance, but during the filling process of milk powder, since milk powder is a fine particle, it is easy to splash everywhere, causing pollution to the environment and equipment

The dust collection equipment in the prior art is covered on the filling nozzle of the filling machine through a circular cover. There is suction from the extension in the cover, which can suck away the powder splashed everywhere. However, due to the large space in the cover, the suction of the fan It is also relatively large, and it is easy to suck away the powder that has been filled into the iron can, resulting in a decrease in filling accuracy.
