Stirring scraper of ice cream machine

Abstract

The invention discloses a stirring scraper of an ice cream machine. The stirring scraper of an ice cream machine comprises a base rod and at least one scraper piece arranged on the base rod, wherein the scraper pieces are laterally and slidably arranged on the base rod; and an elastic piece is arranged between each scraper piece and the base rod and is used for pushing the scraper piece away from the base rod. When the stirring scraper rotates in a scraping barrel, the elastic pieces can continuously press the scraper pieces on the inner wall of the scraping barrel to prevent missing positions, the scraping effect is guaranteed, therefore, the quality of produced ice cream can be guaranteed effectively, the scraper pieces can also adapt to change of the distance between the base rod and the inner wall of the scraping barrel and swings back and forth, overlarge pressure on the inner wall of the scraping barrel cannot be produced, the circumstance that the stirring scraper and the scraping barrel are damaged due to over-large stress can be avoided, processing and assembling errors can be compensated, rate of breakdown is reduced, and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of ice cream machines, in particular to a stirring scraper for an ice cream machine. Background technique [0002] Ice cream machines are widely used in homes and shopping malls, and can quickly process liquid ice cream raw materials into solid or semi-solid ice cream. The scraping cylinder is refrigerated, so that the ice cream raw materials in the scraping cylinder are solidified rapidly, and then the solidified ice cream raw materials are scraped off and transported out by the stirring scraper in the scraping cylinder to form finished ice cream products. In the current ice cream machine, its stirring scraper usually includes a base rod and a scraper blade fixed on the base rod, and the base rod is driven by a motor to rotate so that the scraper blade can rotate in the scraping cylinder to scrape material. Due to the unavoidable processing and assembly errors in manufacturing, the mixing scraper and scraper cylinde...

Problems solved by technology

In the current ice cream machine, its stirring scraper usually includes a base rod and a scraper blade fixed on the base rod, and the base rod is driven by a motor to rotate so that the scraper blade can rotate in the scraping cylinder to scrape material. Due to the unavoidable processing and assembly errors in manufacturing, the mixing scraper and scraper cylinder are also prone to deformation during use, which makes it difficult for the movement track size of the outer edge of the scraper blade to accurately match the inner diameter of the scraper cylinder, and the scraper cylinder is also prone to deformation. Eccentric deformation occurs, and the stirring scraper is easy to coincide with the central axis of the scraping barrel, and it is easy to deviate. Therefore, when the movement track size of the stirring scraper is larger than the inner diameter of the scraping barrel, it is easy to cause scratch damage to the scraping barrel or damage the stirring Scraper, when the size of the movement track of the stirring scraper is smaller than the inner diameter of the scraper cylinder, ice cream ingredients that cannot be scraped will be left on the scraper cylinder. These ice cream ingredients are prone to excessive hardening after long-term refrigeration and are easy to gradually superimpose and expand. The rotation of the stirring scraper, even if it is finally scraped off by the stirring scraper, is not easy to break due to the hardness angle, which may easily cause blockage of the ice cream machine and other faults and affect the taste and eating of the ice cream product
