Description

Technical Field

[0001] The utility model relates to the technical field of filling mechanisms, in particular to an upper weighing type filling mechanism. Background Art

[0002] The most widely used filling method for edible oil filling machines is the flow meter metering method.

[0003] However, this type of flow meter metering filling equipment in the prior art has the following disadvantages:

[0004] 1. All are measured by the volume of oil. As the environment changes (seasonal changes, morning and noon temperature changes), the liquid will be affected by the temperature of the environment, and the principle of thermal expansion and contraction will cause the volume of the liquid to change, thus affecting the filling accuracy.

[0005] According to the application number 201510698408.5, a top weighing filling machine can perform quantitative weighing and filling by using the weighing device at the top. However, during filling, the lower filling head cannot be deeply inserted into the bottle to be filled. Therefore, when filling bottles with larger openings, the filling liquid may splash and be wasted due to the large height difference of the filling.

[0006] Therefore, an upper weighing filling mechanism is needed to improve the above-mentioned problem. Utility Model Content
