Abstract
Description
Technical Field
[0001] The invention relates to the technical field of corn tip cutting, in particular to a device for positioning and cutting the tip of fresh corn. Background Art
[0002] Fresh corn refers to young, tender corn with a unique flavor and quality, also known as fruit corn. During the milky stage of the kernels, fresh corn produces a high concentration of sugar, starch, crude fat, and various vitamins and amino acids, making it extremely nutritionally valuable. For example, sweet corn is rich in vitamins A, B1, B2, and C, as well as minerals and free amino acids. Every 100 grams of edible sweet corn contains 3.2 grams of protein, 1.2 grams of fat, 19 grams of carbohydrates, and 0.7 grams of fiber, among other nutrients. Glutinous corn, on the other hand, contains a significant amount of selenium, which has anti-aging effects on the cardiovascular system. Its rich content of xanthocyanins can also treat dark spots on young women's faces. The fresh corn positioning and tipping device is an automated device specifically designed for tipping fresh corn, designed to improve processing efficiency and product quality. Tipping is a critical step in the fresh corn processing process. Traditional manual tipping methods suffer from low efficiency, high labor costs, and inconsistent tip lengths. With the development of agricultural mechanization, in order to improve production efficiency, reduce labor costs, and meet the market's requirements for consistent quality of fresh corn, it has become particularly important to develop a fresh corn positioning and cutting device.
[0003] After searching, the invention patent with Chinese patent number CN110271044B discloses a device for positioning and cutting the tips of fresh corn ears. The present invention is provided with a visual detection mechanism and a controller. The visual detection mechanism can identify the size and position of the corn to be cut and can classify it according to the size. The controller can automatically adjust the diameter size of the positioning mechanism according to the recognition and size classification of the corn by the visual detection mechanism. In this way, the problem of cutting too large or too small ears of corn of different sizes when cutting and positioning the ears can be avoided, and the problem of waste caused by cutting too large corn can be reduced as much as possible. At the same time, automatic transmission, automatic pushing and cutting can be achieved. The present invention is provided with an ear cutting device. The ear cutting device is driven by a motor to drive the slice to perform an up and down cutting movement, thereby being able to cut the tip of the corn ear, replacing the traditional manual ear cutting process and reducing the labor intensity of the staff.
[0004] However, in actual use of the above device, the circular groove above is moved by the transmission belt. However, when the positioning mechanism fixes the corn, due to the different sizes of the corn, the smaller corn may slide inside the circular groove when fixed, so that the corn may be cut too long or too short when the tip is cut, which reduces the working efficiency of the device. Therefore, a fresh corn positioning and cutting device is proposed. Summary of the Invention
