CN2223186Y - Domestic micro-screw oil press - Google Patents

Abstract

The utility model relates to a domestic micro oil press, comprising a machine frame, a body case, a screw shaft in the body case, a thread adjusting handle, a speed reducer and an electric motor. Compared with a conventional oil press, the domestic micro-screw oil press has different parts that a discharging end of a spiral gap adjusting device replaces a traditional feeding end, thereby, the stress structure of each part is altered, and the binding force is more reasonable. In addition, a reducer output shaft and the screw shaft adopt a flat and square connection mode. The utility model has the advantages of simple structure, small size, light weight, low cost, easy machining, and convenient assembly and disassembly. The utility model is a micro oil press and suitable for squeezing oil materials such as rapeseed, cotton seed, soy bean, peanut kernel, sesame, etc. at homes.

Description

The domestic miniature screw oil expeller

The utility model belongs to the domestic miniature screw oil expeller of oil crops such as a kind of expressed oil vegetable seed, cottonseed benevolence, soybean, shelled peanut, sesame.

Existing small-sized oil press has two types: a kind of is hydraulic oil press, and a kind of is spiral oil press.Spiral oil press is lighter than fluid pressure type oil press.Now its transmission principle of spiral oil press, version are almost completely identical on the market.Oil press when work stressing conditions is as follows: one, screw bearing compression chord, because helical axis is slender axles, thereby axle is little can produce after to a certain degree crookedly, has limited the miniaturization of axle like this; Three, shell is subjected to tension, shell is cylinder iron made often, and the tensile strength of cast iron is far smaller than compression strength, and it is stressed not ideal enough, need take to increase shell sizes for this reason and add measures such as bearing a part of pulling force with two steel axles to remedy the not defective of tension of cast iron.Make this oil press complex structure like this, the manufacturing cost height.Thereby this product will enter just comparison difficulty of huge numbers of families.

The purpose of this utility model provide a kind of simple in structure, volume is little, in light weight, domestic miniature screw oil expeller that cost is low.

The purpose of this utility model is achieved in that and is fixed with cylinder blanket (4) on frame (11), design has charging aperture (6) on an end surfaces of shell (4), be fixed with decelerator (8) by screw on an end face of shell (4), this decelerator is connected with the motor (12) that is fixed on frame (11) bottom by belt (9); Design has a hole on another end face of shell (4), lay discharging circle (3) in the hole, the slit that one taper is arranged between the interior annular distance face of this discharging circle (3) and helical axis (5) surface, when discharging circle (3) weares and teares, can change, have an end of adjusting support (18) to connect by bolting on this end face, be provided with regulating handle (2) in the other end of support (18), design has ball bearing (17) in the regulating handle (2), and regulating handle (2) is gone up design set lever (1); Design has a helical axis (5) in the cavity of shell (4), and an end of this helical axis is connected by the flat square key of flat square groove with decelerator (8) output shaft; Fixed cover (20) point is welded in the flat square groove outside of helical axis, can make helical axis (5) produce axial displacement under the effect of regulating handle (2), and loading and unloading are convenient in the not transmission of influence power.The other end of helical axis (5) is fixed on the bearing (17) of regulating bracket end face after passing the discharging circle (3) that is placed in shell (4) the one end face shrinkage pools and regulating support (18); By screw (16) pad (15) regulating handle (2) is connected with helical axis (5) end face, be equipped with 1～2 blade on the helical axis (5) in regulating support (18), get into the dregs of fat of regulating in support (18) chamber in order to chopping, make it outside support (18) outlet at bottom is fallen into discharge bucket (13) output machine, there are many to press bars (19) in design on shell (4) cavity wall and between the helical axis (5), make the fluid that is squeezed out outside fuel-displaced bucket (10) outflow machine is bled in the slit of pressing bar (19).

The utility model has the advantages that: 1, because this machine changes screw thread adjusting means into discharge port end by traditional feed inlet end, this machine of making shell is by being subjected to tension to change compression chord into, helical axis is changed into by compression be subjected to tension, again because this machine adopts compression strength to manufacture shell greater than the cast iron of tensile strength, adopt the elongated helical axis of tensile strength greater than bending strength, thereby can reduced volume, weight reduction, reduce cost, be convenient to microminiaturization.

2, because helical axis and reducer output shaft adopt flat square groove key and fixed cover connected mode, be convenient to processing and loading, unloading, help family and use.

Introduce an embodiment below in conjunction with accompanying drawing:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the A-A profile among Fig. 1.

With reference to accompanying drawing: welding one charging aperture (6) on an end surfaces of cylinder blanket (4), in the cavity of shell (4), be screwed many and press bar (19), and lay a helical axis (5), one end of helical axis (5) is by flat square groove, the key mode is fixed on the output shaft of decelerator (8), the other end of helical axis (5) is fixed on two bearings (17) of slack adjuster after passing the discharging circle (3) that is placed on the shell (1) and regulating support (18), this gap adjustment dress bag is put regulating handle (2) set lever of drawing together on support (18) outer face (1), two bearings (17) and pad (15) and screw (16), be fixed with motor (12) in the bottom of frame (11), the main shaft of motor is connected with decelerator (8) by belt (9), at the end of frame (11) near adjusting support (18), be fixed with discharge bucket (13), frame (11) is fixed with fuel-displaced bucket (10) near an end of shell (4) bottom.During work, material enters in the housing chamber from feed hopper (6), and motor drives the helical axis rotation through decelerator, and the fluid that squeezes out flows out from fuel-displaced bucket (10), and the dregs of fat flow out from discharge bucket (13).

Claims (1)

1, a kind of domestic miniature screw oil expeller, comprise the shell (4) that is fixed on the frame (11), motor (12), discharge bucket (13), fuel-displaced bucket (10), the feed hopper (6) on shell (4) surface, the decelerator (8) of shell (4) one ends, the adjusting support (18) of the other end, many in shell (4) cavity are pressed bar (19) and helical axis (5), it is characterized in that: slack adjuster is installed in the discharge end of this machine, it comprises the discharging circle (3) that is placed in shell (4) end-face hole, be fixed on the adjustment support (18) on this shell end face, adjust the regulating handle (2) of support (18) other end by being threaded, two bearings (17) of fixing in the regulating handle (2), fixing an end of helical axis (5) in the bearing (17), this end face is by screw (16), pad (15) is connected with regulating handle (2); The other end of helical axis (5) preferably is connected with the flat square key of decelerator (8) output shaft by flat square groove, and helical axis (5) can be given birth to axial displacement under the effect of regulating handle (2).
