Taking the yueshan 200 as an example, the yueshan 200 is a sphere with two flat ends, and the fruit peeling apparatus 100 of the present embodiment is realized by clamping the yueshan 200 by the pressing rod 41 and the top fork 33 and rotating the yueshan 200 along with the top fork 33 during the peeling process of the yueshan 200. In the clamping process, the stroke of the moving of the top fork 33 towards the press rod 41 is fixed, the press rod 41 is pushed by the pressing driving piece 43 to move downwards to prop against the persimmon 200, the distance of the moving of the press rod 41 towards the top fork 33 floats up and down according to the size of the persimmon 200, and therefore the distance from the lower end of the press rod 41 to the top fork 33 is equal to the diameter D of the persimmon 200. In order to allow the rotation axis 520 of the tool holder 53 to face the equator 210 of the yueshi 200 (fig. 12, in the present embodiment, the equator 210 of the yueshi 200 is a circumferential line having the longest circumference in the locus of the surface of the yueshi 200 along the rotation of the yueshi 200), the perpendicular distance between the rotation axis 520 of the tool holder 53 and the top hairpin 33 is required to be the radius R of the yueshi 200. D/R is always equal to 2 regardless of the size of the persimmon 200, and therefore, the stroke of the pressing lever 41 is required to be 2 times as long as the stroke of the peeling assembly 5 for peeling the persimmon 200. In the embodiment, because the fixing member 46 is connected with the middle position of the linkage rod 62 through the driving rod 63, the stroke of the pressing rod 41 is twice that of the peeling assembly 5, i.e. in the embodiment, the stroke ratio of the peeling assembly 5 to the pressing rod 41 is 1:2, so that the rotation axis 520 of the knife rest 53 in the peeling assembly 5 can always be aligned to the equator 210 of the euyule persimmon 200 no matter the size of the euyule persimmon 200, i.e. the middle position of the pressing rod 41 and the top fork 33, so that the peeling knife 55 can be better attached to the surfaces of the euyule persimmons 200 with different sizes, the fruit peels completely and uniformly, and the waste of the fruit pulp when the fruits with different sizes are peeled is reduced.

In addition, in the present embodiment, the rotation axis 520 of the knife rest 53 of the peeling assembly 5 does not intersect with the rotation axis of the fork 33, but deviates from the rotation axis by a distance S (fig. 13), and the traveling trajectory of the peeling knife 55 after rotating 180 ° around the rotation axis 520 of the knife rest 53 is L1, and this trajectory L1 is more in contact with the appearance of the yueshi 200 with two flat ends, which can further improve the peeling quality, and at the same time, the cutting edge 557 of the peeling knife 55 is parallel to the surface of the yueshi 200 at the two extreme positions (similar to the north and south poles of the earth) of the yueshi 200, thereby avoiding the interference of the peeling knife 55 with the fork 33 and the pressing rod 41. If the rotation axis 520 of the knife rest 53 of the peeling assembly 5 intersects with the rotation axis of the fork 33, the traveling track of the peeling knife 55 after rotating 180 ° around the rotation axis 520 of the knife rest 53 becomes L0, and it is obvious that the track L0 is far from the shape of the yueshan 200, which may reduce the peeling quality, and the peeling knife 55 may interfere with the fork 33 and the pressing rod 41, thereby affecting the peeling operation.

In conclusion, in the fruit peeling apparatus 100, the stroke of the moving of the push fork 33 towards the press rod 41 is not changed, so that the stroke of the moving of the press rod 41 towards the push fork 33 is related to the height of the fruit, and the rotation axis of the knife rest 51 in the peeling assembly 5 can be closer to the equator of the fruit by linking the peeling assembly 5 with the press rod 41, so that the peeling knife 55 can be better attached to the surfaces of the fruits with different sizes, the waste of pulp when the fruits with different sizes are peeled is reduced, the peeling quality of the fruits with different sizes can be improved, the fruits do not need to be classified and screened before being peeled, and the production efficiency is further improved.
