as shown in fig. 2 and 4, the grapefruit 10 is fixed on the four pins 41 at the outer end of the support rod 4 at the feeding position at the front end of the conveyor line 2, so that the bottom of the grapefruit 10 is supported on the push block 51, then the conveyor line 2 drives the moving seat to intermittently move, after the grapefruit 10 moves to approach the screw 6 and stops along with the support rod 4, the driven gear 42 on the support rod 4 is meshed with the driving gear 63, the push member 25 firstly pushes the cutter bar 8 to move so that the peeling cutter head 83 does not contact with the grapefruit 10, then the second motor 61 is started, the screw 6 rotates, the driving gear 63 rotates, the grapefruit 10 rotates counterclockwise along with the support rod 4, after the nut 7 moves upwards to drive the cutter bar 8 to separate from the push member 25, the torsion spring 82 drives the cutter bar 8 to approach the grapefruit 10 so that the cutter bar 83 contacts with the peel of the grapefruit 10, and the blade 83, the blade 8321 of the upper scraper 832 can scrape the peel of the grapefruit 10, the cutter bar 8 moves upwards along with the nut 7, and the upper scraper 832 and the lower scraper 833 cooperate with each other to peel the grapefruit 10 relatively quickly. After peeling is finished, the cutter bar 8 moves upwards to the grapefruit 10 along with the nut 7 to give way, and the nut 7 stops moving to the upper position;

then, the conveying line 2 drives the moving seat 3 to intermittently move for one position, the second motor 61 rotates reversely, the screw 6 rotates reversely, the nut 7 drives the cutter bar 8 to reset downwards, then the conveying line 2 drives the moving seat 3 to intermittently move for one position, and the other pomelo 10 reaching the peeling station carries out the peeling operation, so that the production line type peeling operation is formed;

after the grapefruit 10 which is peeled at the peeling station reaches the discharge end of the conveyor line 2 along with the support rod 4 and stops, the material pushing cylinder 14 starts a first stroke to drive the push rod 5 to move through the driving piece 15, the push rod 5 drives the grapefruit 10 to move on the inserting needle 41 through the push block 51 to a set position, and then the left cylinder 94 and the right cylinder 95 act to respectively drive the left clamping block 96 and the right clamping block 97 to clamp the grapefruit 10; then, the driving mechanism 17 drives the door-shaped support 91 to move away from the conveying line 2, meanwhile, the material pushing cylinder 14 starts a second stroke to drive the push rod 5 to move through the driving piece 15, the push rod 5 drives the grapefruit 10 to assist the grapefruit 10 to be separated from the inserting needle 41 through the push block 51, then the left clamping block 96 and the right clamping block 97 clamp the grapefruit 10 to enable the grapefruit 10 to be separated from the inserting needle 41, and then the cutting cylinder 92 drives the blade 93 to cut the peel at the bottom of the grapefruit 10 to completely peel the grapefruit 10, as shown in fig. 10;

then, the peel falling from the bottom of the grapefruit 10 is cut by the blade 93 and enters the collecting barrel 20 along the guide plate 19, then the left air cylinder 94 and the right air cylinder 95 respectively drive the left clamping block 96 and the right clamping block 97 to loosen the completely peeled grapefruit 10, and the grapefruit 10 falls into the guide pipe 18, so that the peeling operation of the grapefruit 10 is completed. Then the cutting cylinder 92 drives the blade 93 to reset, and the driving mechanism 17 drives the door-shaped support 91 to move and reset close to the conveying line 2;

the peeled pomelo 10 enters the can body 1a from the pomelo feeding hole 2a along the guide pipe 18. The crushing cutter shaft 4a is driven by a crushing motor 5a arranged outside the tank body 1a to rotate at a high speed, a plurality of crushing cutters 41a on the outer peripheral surface of the crushing cutter shaft 4a cut and crush peeled pomelos 10, crushed materials and a small amount of pomelo juice generated in the crushing process fall to the inner bottom of the tank body, two scraping plates 42a extend outwards from the lower end of the crushing cutter shaft 4a to scrape the crushed materials and the small amount of pomelo juice into a crushed material discharge port 3a, then these broken back material and a small amount of shaddock juice remove rethread broken material feed inlet 2b along transfer line 6a and get into in the casing 1b of juicer 300, extrusion arbor 3b is rotatory under the drive of motor 4b that squeezes juice, and the spiral extrusion sword 31b on the extrusion arbor 3b outer peripheral face squeezes broken material and squeezes juice, and the juice that squeezes out falls into through liquid outlet 5b and holds in the liquid bucket 51b, and the shaddock sediment that forms after the extrusion was squeezed juice falls into through slag notch 6b and holds sediment bucket 61 b.

During the juicing process, the vacuum pump 400 may be intermittently activated to prevent the crushed material from being clogged in the transfer pipe 6a and to accelerate the crushed material to enter the juicing device 300.

The second embodiment, fig. 11 and fig. 12 show that a grapefruit squeezing production system is different from the first embodiment in that: the grapefruit peeling production lines 100 are different, the conveying line 2 is not provided with pushing pieces at positions close to each supporting rod 4, the lower infrared proximity switch 13 moves upwards on the vertical support 11, and the nut moves downwards and upwards, so that the peeling tool bit 83 on the cutter bar 8 can contact the peel of the grapefruit 10 when the nut is in the moving lower position.

The conveying line 2 drives the moving seat 3 to intermittently shift, so that when the grapefruit 10 arrives at a peeling station, the peel of the grapefruit 10 contacts the peeling tool bit 83 to drive the cutter bar 8 to rotate anticlockwise, the torsion spring 82 drives the cutter bar 8 to lean against the grapefruit 10, and the peeling tool bit 83 can always contact the peel of the grapefruit 10 to peel in the peeling process.

While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
