As shown in fig. 2, 4 and 8, the outer side wall of the taper rod 22 opposite to the oil outlet a6 is a cylindrical surface a27, and the outer side wall of the taper rod 22 opposite to the oil outlet B5 is a cylindrical surface B28; the spiral plate 42 is divided into two sections at a certain axial distance at the cylindrical surface A27; the four sliding chutes C30 are circumferentially and uniformly distributed on the cylindrical surface B28; as shown in fig. 4 and 6, the pressing rod 39 slides along the tapered rod 22 in the sliding slot D31 at the bottom of the corresponding sliding slot C30; one end of the return spring 41 is connected with the end surface of the corresponding slide block 40, and the other end is connected with the inner wall of the corresponding slide groove C30.

As shown in fig. 5 and 10, four cleaning blocks 17 are uniformly distributed in the circumferential direction and mounted on the upper end of the sliding column 16, and the four cleaning blocks 17 are matched with a four-hole strainer 19 mounted on the corresponding oil outlet a 6. The filter screen 19 blocks large oil, and prevents the block oil from entering the oil outlet A6 to seriously block the block oil.

The electric drive module a21 and the electric drive module B33 of the present invention are both of the prior art and both are comprised of a speed reducer, a motor and a control unit.

The working process of the invention is as follows: in the initial state, the outer edge surface of the cam 38 abuts against the ends of the four abutting rods 39, and the outer edge surface of the spiral plate 42 is in clearance fit with the inner wall of the cylinder 3. One spool 16 is open to the corresponding oil drain groove 15, and the other spool 16 is closed to the corresponding oil drain groove 15. The four cleaning blocks 17 of the spool 16 in the closed state of the corresponding oil drain groove 15 are inserted into the four holes of the strainer 19 in the corresponding oil outlet a6, respectively. The pressing rod 39, which abuts against the outer edge surface of the minimum radius on the cam 38, drives the corresponding slide block 40 to retract into the corresponding slide groove C30, and the slide block 40 retracted into the corresponding slide groove C30 is opposite to the oil outlet B5 on the wall of the cylinder 3. Both return springs 41 that return the slider 40 are in a stretched state.

When the oil press is used for pressing oil, the electric drive module B33 is started to operate, the electric drive module A21 is started to alternately operate in a positive and negative mode at certain time intervals, the electric drive module B33 drives the taper rod 22 and the spiral plate 42 on the taper rod 22 to rotate around the central axis of the taper rod 22 relative to the cylinder 3 through the gear B34 and the gear ring 35, and the taper rod 22 drives the four sliding blocks 40 to synchronously rotate. Meanwhile, the electric drive module a21 drives the two sliding columns 16 to alternately slide in the corresponding sliding grooves a13 through the gear a20 and the two racks 18, and the two sliding columns 16 which alternately slide alternately close and communicate the two oil outlets a6 and the corresponding oil leakage grooves 15 and alternately push the oil blocked in the four holes of the filter screen 19 in the two oil outlets a6 into the cylinder 3.

Meanwhile, the cam 38 fixedly connected with the cylinder 3 through the fixed shaft 37 is in sliding fit with the four pressing rods 39, the tail ends of the four pressing rods 39 sequentially interact with the outer edge surface with the smallest radius on the cam 38, and the four pressing rods 39 respectively drive the corresponding sliding blocks 40 to slide in the corresponding sliding grooves C30 in a reciprocating mode under the circumferential sliding action of the outer edge surface of the cam 38. When the slide block 40 is opposite to the oil outlet B5, the abutting rod 39 on the slide block 40 is just abutted against the outer edge surface with the smallest radius on the cam 38, and the slide block 40 opposite to the oil outlet B5 is contracted in the corresponding slide groove C30 under the action of the corresponding two return springs 41.

The fried oil is added into the space between the cylinder 3 and the spiral plate 42 from the funnel 11, the oil is moved by the spiral plate 42 rotating with the taper rod 22 from the conical surface A26 to the conical surface B29, because the pitch of the spiral plate 42 is gradually reduced along the axial movement direction of the oil, the oil is gradually squeezed because the space between the spiral plate 42 is reduced while the oil is moved axially towards the ring sleeve A44 under the driving of the spiral plate 42, the oil in the squeezed oil is gradually squeezed out, and the squeezed oil is firstly leached out by the two oil outlet holes A6 which are alternately switched under the action of gravity and flows into a corresponding container through the oil receiving hopper A43.

As the oil is drained from the two oil outlet holes a6, the dregs flowing along with the oil may block four holes of the corresponding filter screens 19 in the oil outlet holes a6, and if the filter screens 19 blocked by the dregs are not cleaned in time, the oil is drained, and the oil extraction efficiency is further reduced. Two travelers 16 of alternate motion drive corresponding four clearance pieces 17 respectively with certain time interval pass in and out corresponding filter screen 19's four holes fast and will block up in the dregs top income drum 3 in filter screen 19 four holes to the realization carries out quick effective clearance to the dregs that block up in filter screen 19 four holes, thereby guarantees oil outlet A6's the efficiency of producing oil. Meanwhile, the oil drained through the oil outlet A6 is guaranteed not to carry dregs, and the quality of the oil drained at the oil outlet A6 is improved.

As the oil continues to move axially under the action of the screw plate 42, when the oil reaches the space in the cylinder 3 at the oil outlet B5, the oil is further squeezed to further leach more oil, and the oil enters the corresponding container through the oil outlet B5 and the oil receiving hopper a43 under the action of gravity. Since any one of the sliders 40 on the taper rod 22 is rapidly retracted into the corresponding slide groove C30 by the corresponding two return springs 41 and the cam 38 when being opposite to the oil outlet B5, the space of the oil outlet B5 in the cylinder 3 is rapidly increased to a certain extent, so that the extrusion force received by the oil at the oil outlet B5 is rapidly reduced, the oil at the oil outlet B5 is ensured not to be pressed into the oil outlet B5 due to the overlarge extrusion force, the efficiency of the oil outlet B5 is prevented from being reduced due to the blockage of the oil outlet B5 by dregs, and meanwhile, because the oil is further compressed by the conical surface A26 and the spiral plate 42, the oil is tightly pressed and bonded together, the pressed and bonded oil basically does not generate scattered loose dregs, so that the oil outlet B5 is not blocked and the oil drained from the oil outlet B5 is not carried with dregs, thereby ensuring the quality of the oil drained from the oil outlet B5.

As the oil continues to move axially by the screw plate 42, the oil is further pressed and bonded together, and the oil is pressed more tightly. When the pressed oil is pressed tightly from the conical surface A26 of the conical rod 22 into the range of the cylindrical surface B28, the oil is further pressed again along with the further movement of the oil, and final oil residue is formed and discharged through the annular space between the ring sleeve A44 and the conical rod 22.

When the oil is driven by the spiral plate 42 to move in the conical surface B29, the oil is further extruded by the spiral plate 42 with the further reduced pitch, the oil remained in the oil is fully extruded out of the oil, and the extracted oil is drained out through the oil outlet C49 on the inner wall of the conical part 45 of the ring sleeve A44, the oil cavity 48 and the oil outlet D50 densely distributed at the lowest end of the outer wall of the cylindrical part 56 of the ring sleeve A44 and enters the container through the oil receiving hopper B54.

The oil content in the oil residues from the ring sleeve A44 is a little remained, thereby ensuring that the oil residues do not influence the oil yield of the oil due to the oil content.

After the oil residue comes out of the ring sleeve A44, the size of the gap between the cylindrical part 56 of the ring sleeve A44 and the conical surface B29 of the taper rod 22 can be adjusted according to the amount of residual oil in the oil residue, if the oil residue contains more oil, the internal thread sleeve 53 rotates the ring sleeve B52 relative to the ring sleeve A44 by screwing the internal thread sleeve 53, the internal thread sleeve 53 moves axially relative to the cylinder 3, the internal thread sleeve 53 drives the ring sleeve A44 to move axially relative to the cylinder 3 through the ring sleeve B52, the conical part 45 of the ring sleeve A44 is close to the conical surface B29 of the taper rod 22, so that the clearance between the conical surface B29 and the conical part 45 of the ring sleeve A44 is gradually reduced, thereby ensuring that the oil can be subjected to larger extrusion force in the process of space movement between the ring sleeve A44 and the conical surface B29, the residual oil in the oil is squeezed out, so that the oil residue formed by the oil is ensured not to carry the oil basically when coming out from the ring sleeve A44, and the oil yield of the oil is improved. If oil is difficult to come out from the ring sleeve A44, the internal thread sleeve 53 is reversely rotated, the conical part 45 of the ring sleeve A44 is far away from the conical surface B29 of the taper rod 22 through a series of transmission belts to drive the internal thread sleeve 53, so that the space between the conical part 45 of the ring sleeve A44 and the conical surface B29 of the taper rod 22 is enlarged, the gap between the conical surface B29 and the conical part 45 of the ring sleeve A44 is gradually enlarged to a proper size, the oil is guaranteed to smoothly come out from the ring sleeve A44, the oil is not carried, and the oil extraction efficiency of equipment and the oil extraction rate of the oil are improved.

In conclusion, the beneficial effects of the invention are as follows: according to the invention, the pressure of the cylindrical surface A27 and the cylindrical surface B28 on the taper rod 22 is kept unchanged through the oil to the oil outlet A and the oil outlet B, so that the oil in the cylinder 3 is prevented from entering the oil outlet A6 and the oil outlet B5 under the driving of the spiral plate 42 due to the continuous extrusion effect of the conical surface A26, and the oil outlet A6 and the oil outlet B5 are prevented from being blocked. When the filter screen 19 in the oil outlet A6 is blocked, the two sliding columns 16 which slide alternately clean the dregs blocked by the filter screen 19 in the two oil outlets A6 alternately, so that the two oil outlets A6 are kept to be continuously unblocked, and the initial oil yield of the oil in the cylinder 3 is improved.

When the sliding block 40 is opposite to the oil outlet B5, the sliding block 40 contracts into the corresponding sliding groove C30 under the action of the cam 38 and does not extrude oil located at the oil outlet B5, so that the oil is prevented from entering the oil outlet B5 to block the oil outlet B5 under the action of internal extrusion, the oil outlet B5 is ensured to be continuously unblocked, and the oil outlet rate of the oil outlet B5 is improved.

In addition, the axial movement distance of the adjusting ring sleeve A44 on the cylinder 3 enables the distance between the ring sleeve A44 and the cylindrical surface B28 of the taper rod 22, so that the space volume of the slag outlet is adjusted, and the oil residue is kept to be properly extruded. Meanwhile, the oil residue moving on the conical surface B29 of the conical rod 22 is further drained outwards through the oil outlet C49 and the oil outlet D50 on the ring sleeve A44 under the extrusion of oil at the front end, so that the oil residue coming out of the ring sleeve A44 is not carried with oil, and the oil pressing efficiency and the oil discharging quality are further improved.
