Pressing mechanism of oil press

Abstract

The invention discloses a pressing mechanism of an oil press. The pressing mechanism comprises a pressing screw and a pressing barrel matched with the pressing screw. An oil outflow groove is arranged on a side wall of the pressing barrel, a residue outlet is arranged at the tail end of the pressing barrel, the pressing barrel is divided into a front section of conveying cavity and a rear section of pressing cavity, and the diameter of the pressing cavity is smaller than that of the conveying cavity. The pressing screw is divided into a front conveying section corresponding to the conveying cavity of the pressing barrel and a rear pressing section corresponding to the pressing cavity of the pressing barrel, the thread external diameter of the pressing screw becomes small gradually from front to back on the conveying section and is kept constant after entering the pressing section, and the thread internal diameter of the pressing screw becomes large gradually from front to back. The thread pitch of the pressing screw, which is the thread pitch of the pressing section, is smaller than the thread pitch of the conveying section. The conveying cavity of the pressing barrel is a regular polygonal cavity with a taper, and the taper variation of the conveying cavity corresponds to the conveying section of the pressing screw. The pressing mechanism is reasonable in structural design, improves pressing efficiency, is small in size, reduces production cost and can be widely suitable for oil presses of various types.

Description

technical field [0001] The invention relates to an oil press, in particular to a pressing mechanism of the oil press. Background technique [0002] As oil presses are widely used in various household places, people continue to perfect and improve the pressing mechanism of oil presses. The squeezing mechanism of the oil press in the prior art is to accommodate the material particles such as peanuts in the thread pitch of the squeezing screw, and as the screw rotates, the material particles such as peanuts are squeezed in the squeezing cylinder, thereby squeezing out the oil. This kind of squeezing principle makes the screw tooth height and thread spacing of the squeezing screw must be large enough to accommodate material particles such as peanuts. In this way, the squeezing screw and the matching squeezing barrel must be relatively large in volume and must be long enough to The material particles such as peanuts are fully squeezed, and finally the size of the squeezing mecha...

Problems solved by technology

This kind of squeezing principle makes the screw tooth height and thread spacing of the squeezing screw must be large enough to accommodate material particles such as peanuts. In this way, the squeezing screw and the matching squeezing barrel must be relatively large in volume and must be long enough to So that peanuts and other material particles can be fully squeezed, resulting in a large size of the squeezing mechanism
