The juice extracting crank 411 and the peeling crank 404 are driven by a belt 405, the belt 405 is covered by a shell seat 417, and the shell seat 417 is assembled on an installation seat 419 to protect the driving safety of the belt 405, facilitate the installation of the juice extracting crank 411 and the peeling crank 404 and ensure that the whole assembly structure is more compact; the peeling crank 404 is driven by a motor 418, as shown in fig. 17, 19 and 20.

When the incision juice extracting device 4 works, the peeling crank 404 is driven by the motor 418 to rotate, and the peeling crank 404 drives the juice extracting crank 411 to rotate through the belt 405. Wherein, the juice extracting crank 411 drives the extruding plate 409 to move upward relative to the fixed sliding seat 410 so as to avoid the interference between the sliding tool holder 402 and the extruding plate 409. Then, the sliding tool holder 402 is driven to advance by the peeling crank 404 until the peeling tool 403 cuts off a part of the peel of the passion fruit which is clamped and straightened by the straightening device 3. The cut peel enters a peel separation box 605, after being filtered by a sieve tray 603 in a hollow cavity of the peel separation box 605, the juice enters a juice collecting box 606, and the peel enters a peel collecting box 602. When the peeling crank 404 drives the peeling cutter 403 to retreat, the two squeezing plates 409 move towards each other under the action of the driving mechanism to form squeezing action, that is, the juice extracting crank 411 drives the connecting rod frame 406 to move downwards relative to the fixed sliding seat 410 through the juice extracting connecting rod 414, and the movable sliding seat 407 slides outwards relative to the connecting rod frame 406 within the limited range of the strip-shaped groove 406a, so that the two squeezing plates 409 can be driven to approach each other through the upper connecting rod 408 and the lower connecting rod 413 to form squeezing action. In the process that the squeezing plates 409 continuously descend, the bottom of the squeezing plates 409 are gradually inserted into the passion fruit from the position, with the peel cut off, of the passion fruit, meanwhile, the two squeezing plates 409 move oppositely to form squeezing action, juice can be squeezed out through the squeezing plates 409, and the squeezed juice enters the juice collecting box 606 to be collected.

In order to ensure the reliability and stability of the extrusion action of the two extrusion plates 409, the link frame 406 and the guide wheel 415 may form a movable connection structure, the fixed slide 410 is provided with a guide groove 410b, and a limit groove 410a for accommodating the extrusion plates 409 is formed in the hollow cavity of the fixed slide 410, as shown in fig. 17; and, when the link frame 406 linearly moves up and down with respect to the fixed slider 410, the guide wheel 415 linearly moves within a range defined by the guide groove 410 b. In addition, 2 peeling cutters 403 on the sliding cutter frame 402 can be arranged, and 2 peeling cutters 403 are arranged in parallel relatively, as shown in fig. 19, so that the sliding cutter frame 402 can simultaneously cut off the peels of the upper and lower ends of the clamped and aligned passion fruit by using 2 peeling cutters 403 through one action stroke, which is beneficial to improving the juice extracting efficiency of the incision juice extracting device 4.

After the juice extraction operation is performed on the clamped and aligned passion fruit by the incision juice extraction device 4, a large amount of pulp remains in the passion fruit. To avoid waste, a pulp scraping device 5 can be additionally arranged. As shown in fig. 21 and 22, the pulp scraping device 5 mainly includes a left fixed scraper 504, a right fixed scraper 507, a connecting seat 502 and a driving mechanism thereof, the driving mechanism of the connecting seat 502 includes an electric push rod 501, the electric push rod 501 is supported by a fixed support 511, and an action output end of the electric push rod 501 is fixedly connected with the connecting seat 502. The left fixed scraper 504 and the left sliding seat 503 are fixedly connected, a peel channel is formed between the edge part of the left fixed scraper 504 and the left sliding seat 503, the right fixed scraper 507 and the right sliding seat 510 are fixedly connected, and a peel channel is formed between the edge part of the right fixed scraper 507 and the right sliding seat 510. When the pulp scraping device 5 works, the connecting seat 502 drives the left slide carriage 503 and the right slide carriage 510 to synchronously and linearly move in the same direction under the action of the driving mechanism. Specifically, the method comprises the following steps:

after the ring cam 204 rotates a certain angle, the finger cylinder 302 fixedly connected with the ring cam is driven to rotate the same angle, so that the passion fruit clamped and aligned on the aligning device 3 and processed by the incision juice-taking device 4 rotates to the working position of the pulp scraping device 5. The electric push rod 501 drives the connecting base 502 to move linearly downward, and the connecting base 502 drives the left slide carriage 503 and the right slide carriage 510 to move linearly downward synchronously. In the process that the left sliding seat 503 and the right sliding seat 510 synchronously move linearly downwards, the peel on the passion fruit is located in the peel channel, and the left fixed scraper 504 and the right fixed scraper 507 move downwards, so that the passion fruit on the straightening device 3 can be subjected to pulp scraping operation. The pulp and juice fall through the pulp separating box 604, and the pulp is screened out through the sieve tray 603 on the pulp separating box 604 and falls into the pulp collecting box 601, while the juice enters the juice collecting box 606.

In order to ensure the smooth operation of the pulp scraping device 5 and improve the pulp scraping efficiency, a left guide pulley 505 may be disposed on the left sliding seat 503, a movable connection structure that rotates relatively is formed between the left guide pulley 505 and the left sliding seat 503, and a peel channel is formed between the left guide pulley 505 and the cutting edge portion of the left fixed scraper 504; similarly, a right guide pulley 508 may be disposed on the right sliding seat 510, a movable connection structure for relative rotation is formed between the right guide pulley 508 and the right sliding seat 510, and a peel channel is formed between the right guide pulley 508 and the cutting edge portion of the right fixed scraper 507. Therefore, during the operation of the pulp scraping device 5, the peel of the passion fruit is positioned in the peel channel, and the left guide pulley 505 and the right guide pulley 508 can respectively form rolling friction through contact with the outer peel of the passion fruit.

In order to further improve the efficiency of the pulp scraping operation of the pulp scraping device 5 and reduce the residual pulp waste, the connecting seat 502 may be respectively formed with the left slide carriage 503 and the right slide carriage 510 as a sliding fit structure, and a second tension spring 509 is disposed between the left slide carriage 503 and the right slide carriage 510, as shown in fig. 22.

In the process of increasing the distance between the left fixed blade 504 and the right fixed blade 507, the front movable blade 506 and the rear movable blade 513 respectively extend outwards relative to the left fixed blade 504 and the right fixed blade 507; during the process of reducing the distance between the left fixed blade 504 and the right fixed blade 507, the front movable blade 506 and the rear movable blade 513 retract inward relative to the left fixed blade 504 and the right fixed blade 507, respectively. The edge portions of the left fixed blade 504, the front movable blade 506, the right fixed blade 507, and the rear movable blade 513 are formed in a circular arc shape as shown in fig. 23 and 24.
