Description

Technical Field

[0001] This utility model relates to the field of agricultural product processing equipment technology, and in particular to a prickly pear peeling mechanism. Background Technology

[0002] In the traditional prickly pear processing, the top-shaving process relies on manual operation: after removing the flower part at the top of the prickly pear, some of the pulp also needs to be removed, resulting in waste of raw materials; the depth and angle of the top-shaving depend on manual experience, which easily leads to uneven top-shaving; moreover, manual operation is time-consuming and labor-intensive, with high labor costs and low processing efficiency.

[0003] In existing automated prickly pear slicing equipment, the structural design of the head-cutting mechanism still has shortcomings: some equipment uses a single cutting tool, which is difficult to adapt to the irregular shape of prickly pears; some equipment cuts by rotating a fixed tool, which cannot adjust the cutting depth synchronously, resulting in waste of fruit pulp or incomplete cutting; in addition, the coordination between the head-cutting process and the feeding and slicing processes is poor, which affects the overall processing efficiency.

[0004] Therefore, there is an urgent need for a prickly pear shaving head mechanism that is compact in structure, can accurately control the shaving depth, can operate synchronously with the production line, and can shave evenly, in order to solve the above-mentioned technical problems.

[0011] As a further technical solution of this utility model, the lifting guide seat is slidably connected to the movable table through the upper guide column, and the lifting tube passes through the rotating sleeve and is connected to the needle bar drive plate bearing. Since the needle bar drive plate is slidably installed on the lower guide column, the lower guide column plays a guiding role in the up and down movement of the needle bar drive plate.
