Description

TECHNICAL FIELD

[0002] Lettuce is also known as Lactuca sativa, a herbaceous plant of Lactuca sativa var. capitata L. of Lactuca L. of Compositae. It is also known as stem lettuce, lettuce shoot, green shoot, and lettuce. The above-ground stem is edible, the stem skin is white-green, the stem is crisp and tender, the young stem is emerald green, and it turns white-green after maturity. The main edible part is the tender stem, which can be eaten raw, cold, fried, dried or pickled, and the tender leaves can also be eaten. The stems and leaves contain lactucin and lactucin. It tastes bitter and has analgesic effect.

[0003] Traditionally, the operation of peeling lettuce is mostly done manually, which is very low in efficiency. Therefore, automatic peeling mechanical equipment emerges as the times require. In the prior art, the publication (announcement) number CN104188061B discloses a lettuce peeling machine, which adopts two symmetrical V-shaped conveying belts arranged above and below to form a conveying channel, a combined cutter assembly includes a center-opening circular cutter holder seat, six cutter head assemblies are arranged on the circular cutter holder seat at equal intervals, any cutter head assembly includes a gas cylinder, the front end of the piston rod of the gas cylinder is fixed with a Y-shaped three-blade cutter, when the six piston rods are stretched to the center position of the circular cutter holder seat, the six three-blade cutters jointly form a regular dodecagon structure; the discharge assembly includes two elastic wheels arranged symmetrically above and below, a discharge channel is formed between the two elastic wheels; the discharge channel, the center opening of the circular cutter holder seat and the feeding channel are sequentially connected. When peeling, the lettuce is put into the feeding end and transported forward along the V-shaped conveying belt, at this time, the material is pushed open the cutter holder by the guide block on the cutter holder to enter the combined cutter head, the six Y-shaped three-blade cutters simultaneously peel the lettuce, after the photoelectric switch senses, the transmission signal is delayed, when the lettuce completely passes through the combined cutter head, the gas cylinder works to drive the cutter head to retreat, the air blowing pipe blows the cutter head to blow away the lettuce skin residues remaining on the cutter head, and the finished product and the peeled lettuce skin are sent out from the discharge channel by the rotation of the elastic wheel.

[0004] However, the above-mentioned lettuce peeling machine has the following problems in actual use:

Each Y-shaped cutter is separately provided with a gas cylinder, so it is difficult to ensure that all the gas cylinders have the same extension amount at the same time, so that the cutter is difficult to form a regular dodecagon structure, thereby affecting the quality of peeling the lettuce.

[0007] 3. When the lettuce is pushed into the combined cutter head by the guide block, the lettuce rubs against the guide block, so that the scraped-off lettuce skin is easily gathered at the guide block, affecting the peeling quality.

[0008] 4. The blowing pipe has poor cleaning effect on the residual lettuce skin on the cutter head, and manual cleaning of the residual lettuce skin is needed after processing dozens of lettuces at a time, reducing the processing efficiency. SUMMARY
