Description

A screw juicer mechanism of a freshly squeezed juice vending machine

technical field

The invention relates to the technical field of freshly squeezed juice vending equipment, in particular to a screw juice squeezing mechanism of a freshly squeezed juice vending machine.

Background technique

The freshly squeezed juice vending machine can realize the automatic juicing and selling of fruits, has the advantages of small footprint and low labor cost, and replaces the traditional artificial juice selling method to a certain extent.

The existing fresh juice automatic vending machine can be referred to CN109658614A, which discloses a fruit juice automatic vending machine, including a cabinet, in which a fruit storage device, a fruit transport device, a juice extraction assembly, a juice receiving device, a packing device and cleaning device, etc. After the juice extraction component squeezes the fruit, some juice and pomace will remain in it, which is easy to spoil and deteriorate. Please refer to paragraph 0049 of the instruction manual of this document. device, it can be seen that the cleaning device can only wash the feed inlet of the juice extraction assembly, relying on the flow of water to clean the inside of the juice extraction assembly, and the pomace is more likely to adhere to the downstream of the juice extraction assembly, such as the filter that is blocked at the juice outlet. On the Internet, the cleaning device cannot effectively clean up the pomace remaining in the downstream of the juicing assembly. In practical application, in order to ensure the cleanliness of the juicing components, in addition to the simple cleaning of the cleaning device, it needs to be manually dismantled and cleaned every day, which increases the operating cost of the fruit juice vending machine.

In order to reduce cleaning costs and ensure hygienic requirements, CN208444379U discloses a freshly squeezed fruit juice vending machine, which includes a bag taking device and a squeezing device, which can realize fruit bagging and squeezing, and prevent juice from remaining on the squeezing device. However, in order to prevent the fruit juice from overflowing, the automatic vending machine cannot cut the fruit into slices, and the squeezing device must squeeze the whole fruit, resulting in a larger volume of the squeezing device, which in turn leads to a larger space occupation of the automatic vending machine. In addition, the automatic vending machine must also be equipped with a bag taking and opening device for bag pressing, which increases the failure rate, manufacturing cost, maintenance cost and space occupation of the equipment.

The screw juicer squeezes the fruit in the squeeze tube by driving the screw shaft with the screw blades to rotate, and the helix angle generates thrust to squeeze the fruit in the squeeze tube. It has the advantages of simple structure, large squeezing force, small space occupation, and no blockage. CN2776212Y discloses an electric juice extractor, which includes a juice extractor, a screw squeezer rod, a motor, a screw cover, a slag outlet, etc. Fruits are put in from the feed port at the upper end of the juicer rod, and the screw juicer rod rotates. After being squeezed, the juice flows from the outlet hole at the bottom of the juicer to the juice cup, while the pomace is driven to the screw cap at the front of the juicer and discharged from the outlet. It can be seen that the existing screw juicer must be manually disassembled and cleaned, and cannot be applied to a freshly squeezed juice vending machine.
