Description

Technical Field

[0001] The invention relates to a production line for pineapple stem removal, automatic petal separation, petal separation guidance, and flesh digging, belonging to the technical field of food processing. Background Art

[0002] Pineapple is a tropical fruit well-suited for deep processing, boasting high water content, rich nutrition, and a delicious flavor. However, its appearance and structure are more complex than typical fruits, with hard leaves covering its entire body and black spots dotting its flesh. Therefore, pineapple pre-processing is typically done manually. This involves manually removing the head and tail, separating the pineapples into segments, arranging the segments in a certain direction, peeling them, and finally, scooping out the flesh. This entire process is essentially manual. Even where production equipment exists, it only operates on a few simple steps, resulting in a minimal degree of mechanization. Current processing machines have yet to fully replace manual labor. Besides being inefficient and yielding low yields, manual processing also suffers from poor hygiene and a high risk of workplace accidents. Summary of the Invention

[0075] The fruit is transported to the present invention and falls on the front conveyor belt 11, is positioned between the two conveying baffles 10, the conveying baffle 10 moves forward, and the front conveyor belt 11 moves to the left, and under the combined force of the two, the fruit constantly moves forward to the left, and the fruit moves to the leftmost end on the front conveyor belt 11 and is blocked by the left edge baffle 26, so that it does not fall out from the leftmost end of the left conveyor belt, and the fruit continues to move forward to the front pad 12, and is cut off by the left cutter 16. The fruit stem or the bottom is thus completed. The conveying baffle 10 drives the fruit to continue to move forward on the rear conveyor belt 13, and the conveying baffle 10 moves forward, and the rear conveyor belt 13 moves to the right, and under the combined force of the two, the fruit constantly moves forward to the right, and the fruit moves to the rightmost end on the rear conveyor belt 13 and is blocked by the right edge baffle 27, so that it does not fall out from the rightmost end of the right conveyor belt, and the fruit continues to move forward to the rear pad 14, and is cut off by the right cutter 18. The operation of removing the stem of the fruit and removing the bottom is completed so far. The fruit then moves on to the space between the left and right conveyor belts.

[0076] Before the fruit moves between the left and right conveyor belts, the system is debugged by turning the knob 10, which rotates the forward and reverse threaded shaft 48. The two threaded sleeves 49 engage the forward and reverse threads of the forward and reverse threaded shaft 48, respectively, driving the conveyor belt connecting plate 50 to move toward or away from the forward and reverse threaded shaft 48. The left and right conveyor belt guide rails 55 and 56 are fixed to the conveyor belt connecting plate 50, respectively. The distance between the left and right conveyor belt guide rails 55 and 56 also decreases or increases as the conveyor belt connecting plate 50 moves, thereby transporting fruit of different sizes. After the fruit enters between the left and right conveyor belts 57 and 58, the conveyor belt motor 63 is activated, and the conveyor belt begins to operate, transporting the fruit from the inlet end to the outlet end. The cutting motor 59 is then activated, and the segmentation cutter 60 rotates, and the fruit passes through the segmentation cutter 60, and is cut into two segments, thus achieving the purpose of fruit segmentation.

The pressure roller gear 80 drives the first rear pressure roller gear 84 and the second rear pressure roller gear 89 to rotate through the meat digging chain 99. The first rear pressure roller gear 84 drives the first rear pressure roller to rotate. The first rear pressure roller 83 drives the first front pressure roller 82 and the first upper pressure roller 9 to rotate through a rough surface conveyor belt 85. The second rear pressure roller gear 89 drives the second rear pressure roller 88 to rotate. The second rear pressure roller 88 drives the second front pressure roller 87 and the second upper pressure roller 86 to rotate through the second rough surface conveyor belt 90.

[0079] The spherical digging blade motor 96 is started, and the spherical digging blade motor 96 drives the spherical digging blade gear to rotate, thereby driving the spherical digging blade assembly 92 to rotate. The rotation direction of the spherical digging blade assembly 92 is opposite to the forward direction of the pulp.

[0080] After the fruit is conveyed from the flat conveyor belt 67 to the flat plate 78, it is driven forward by a rough surface conveyor belt 85. The distance between the rough surface conveyor belt 85 and the flat plate 78 becomes smaller and smaller, and the fruit is compacted. When it passes through the spherical digging knife assembly 92, it is dug out by the spherical digging knife 95 and flows out from the first meat outlet grille 97; the fruit continues to move forward and is driven forward by the second rough surface conveyor belt 90. The distance between the second rough surface conveyor belt 90 and the flat plate 78 becomes smaller and smaller. The fruit is compacted and passed through the fixed meat digging knife 98. The remaining flesh continues to be scraped out and flows out from the second meat outlet grille 97, thus completing the fruit fleshing process.
