Description

Technical Field

[0001] The utility model relates to a fruit feeding mechanism for a multi-station fruit and vegetable peeling machine, which is applied to the field of fruit and vegetable peeling. Background Art

[0002] The working principle of a fruit and vegetable peeling machine is usually based on the principle of mechanical peeling. The peeling knife is driven by a motor to rotate. At the same time, a fixed clamping device fixes the fruit on the peeling knife. During the rotation of the peeling knife, a certain pressure and cutting force are applied to the fruit, so that friction is generated between the peeling knife and the fruit surface, thereby achieving the purpose of peeling.

[0003] Existing fruit and vegetable peeling machines, such as a multi-mango automatic peeling machine with the patent number CN111869896B, place the mango on the base, fix it through the upper guide wheel, then push the fruit feeding mechanism under the top fruit shaft, and then control the top fruit shafts at both upper and lower ends by a cylinder to fix the mango by top fruit, and then remove the fruit feeding mechanism to peel the mango. The fruit seat is not adjustable. If the base of the peeling machine is not adjustable, it may cause the fruit to be placed unstably, which may bring the following problems: If the fruit moves or rolls during peeling, it may lead to uneven peeling. Fruit damage: The unstable fruit may slide or topple during peeling, which will not only affect the peeling effect, but also may cause damage to the fruit inside the peeling machine. The non-adjustable base may only be suitable for fruits of specific sizes and shapes, and may not be able to effectively fix fruits with irregular shapes or different sizes. Therefore, in view of the above problems, the utility model designs a fruit feeding mechanism for a multi-station fruit and vegetable peeling machine. Summary of the Utility Model
