Description

Technical Field

[0001] The invention relates to an internal and external cleaning machine and a cleaning method which can be used for containers with multiple different inner diameters. Background Art

[0002] In order to meet the requirements of healthy and sustainable economic development, enterprises need to recycle and reuse some discarded containers, which can not only reduce environmental pollution, improve the comprehensive utilization rate of resources, but also reduce the production costs of enterprises themselves. However, the recycled containers need to be cleaned before they can be reused. At present, many enterprises rely entirely on manual cleaning, which not only has low cleaning efficiency and high labor costs, but also has difficulty in ensuring the cleaning effect. Common automatic cleaning machines use a simple cleaning brush for rotary cleaning. This type of cleaning machine is mostly used for containers with smaller inner diameters such as beer bottles. It cannot clean large-diameter containers and cannot clean the outer wall of the container synchronously. Some cleaning machines clean based on the ultrasonic principle, but the cleaning time is long and the equipment cost is high. Some cleaning machines use high-pressure water flow for flushing, which has the disadvantages of consuming a lot of water resources, high cost and difficulty in thoroughly cleaning the corners of the bottle mouth. In short, the existing container cleaning machines on the market are either low in applicability, time-consuming and labor-intensive, or complex in structure, high cost, large footprint, and inconvenient to use, and cannot bring greater benefits to enterprises.
