Description

Grease filling device

Technical Field

The utility model relates to the technical field of filling devices, in particular to an oil filling device.

Background

The grease in the normal state is in a viscous state of semi-liquid. An important characteristic of this is the high viscosity, which facilitates lubrication, insulation and sealing. However, because of the difficulty in taking grease, special pneumatic butter machine is needed to suck the grease, the commonly purchased grease is filled in the grease plastic barrel, the conventional butter machine cannot be suitable for direct installation and use on original plastic grease barrels with different sizes due to the specification and the size of the plastic barrel, and the grease in the grease barrel can only be poured into the barrel of the pneumatic butter machine for sucking and use when the grease machine is used, but the operation has a plurality of inconveniences, and the grease is difficult to directly pour into the barrel of the pneumatic butter machine from the grease barrel due to high viscosity of the grease, so that the grease needs to be scraped manually, time and labor are wasted, and certain waste exists. And this operation not only deteriorates the quality of the original butter, but also causes the suction of the oil pump and even damages the oil pump.

In addition, the problem that the follow-up plate is difficult to separate from the grease barrel (grease filling equipment is difficult to separate) due to the large adsorption force between the follow-up plate and residual grease exists in the conventional grease machine (the conventional grease machine forcedly separates from the grease barrel through large destructive force).

Prior art, such as chinese patent ZL201811197942.8, discloses a butter machine comprising: the pressing plate comprises an oil outlet, and the oil outlet penetrates through the upper surface and the lower surface of the pressing plate; one end of the oil outlet is connected with an oil pump. This patent specification discloses: the grease is sticky solid grease, or the opening area of the grease barrel is slightly larger than the plate surface area of the pressing plate in a common oil barrel, and the grease protrudes into the oil outlet hole in the process of pressing the pressing plate 1 into the oil barrel due to the solid property of the grease, and the oil pump 2 simultaneously pumps the grease in the oil outlet 11, so that the instant use is realized. "the opening area of the grease bucket that this patent selected for use must be slightly greater than the face area of clamp plate, and it has restricted the use of grease bucket, simultaneously because the opening area of grease bucket is greater than the face area of clamp plate, when the clamp plate pushes down, necessarily there is a large amount of air between clamp plate and the grease, need extrude through the cylinder and have the not clean problem of grease extrusion in the extrusion process in the grease bucket.
