Automatic buffering anti-jamming oil pressing device of domestic oil press

Abstract

The invention relates to the technical field of oil presses, in particular to an automatic buffering anti-jamming oil pressing device of a domestic oil press. The automatic buffering anti-jamming oil pressing device comprises a motor, a gear mechanism, a pressing barrel and a pressing bar, a feeding opening and an oil outlet are formed in the pressing barrel, threads and a connecting end are arranged on the pressing bar, a buffering area used for buffering oil pressing raw materials is arranged between the inner wall of the pressing barrel and the pressing bar, and the buffering area is located between the rear end of the oil outlet of the pressing barrel and the rear end of the feeding opening of the pressing barrel. When a user chooses a wrong oil pressing mode to press oil, and too many small-diameter oil pressing raw materials enter the pressing barrel, the oil pressing raw materials can be buffered and circulated in the buffering area, jamming cannot occur, therefore, jamming generated when the user chooses the wrong oil pressing mode is avoided, the pressing bar, the gear mechanism, the motor and other parts are prevented from being damaged or scrapped, the repair rate of the domestic oil press is reduced, and the service life of the domestic oil press is guaranteed. Therefore, the device well solves the problem that jamming easily occurs when the user chooses the wrong oil pressing mode.

Description

technical field [0001] The invention relates to the technical field of oil presses, in particular to an automatic buffering and anti-jamming oil press device for household oil presses. Background technique [0002] The household oil press mainly includes a feeding device and an oil pressing device. The feeding device is used to feed the oil pressing device, and the oil pressing device is used to press peanuts and other oil pressing raw materials, and then separate the oil residue. For example: Chinese patent application numbers are 201320504502.9, 201420045189.1, 201420044011.5 and other patent applications. [0003] The oil press device of the household oil press in the prior art includes a motor, a gear mechanism, a press chamber, and a press bar. The top of the pressing chamber close to one end of the gear mechanism is provided with a discharge opening, which is used to receive the oil pressing raw materials dropped from the discharge opening of the feeding device, and t...

AI Technical Summary

Problems solved by technology

However, when the rapeseed (raw material for oil extraction with a smaller diameter) is put in for oil extraction, the peanut (raw material for oil extraction with a larger diameter) is selected for oil extraction. Because the feeding speed is too fast, too much rapeseed It enters the press chamber through the feed opening, and the power of the motor of the household oil press machine is not large, which can easily cause the press rod to be stuck in the press chamber and cannot rotate (that is, the machine is stuck). When the machine is jammed, due to the motor Continue to drive the gear mechanism to work, which will cause the connecting end of the press rod to be screwed (for example: twisted into a twist) and the press rod will be scrapped or the gear mechanism and motor will be damaged and scrapped. damaged severely

In addition, due to the different hardness of some oil-extracting raw materials, there will be jams

[0006] Therefore, how to prevent the machine from jamming when the user chooses the wrong oil extraction mode or the hardness of the oil extraction raw materials is different is a problem that cannot be solved in the household oil press industry so far.

However, the current manufacturers can only specially mark to remind the user to choose the correct oil extraction mode. When the user chooses the wrong oil extraction mode, the machine will still be stuck.
