Description

Technical Field

[0001] The invention relates to the field of automation, and in particular to an ultraviolet sterilizer for a square cotton piece machine. Background Art

[0002] At present, ultraviolet rays are light with a wavelength of 10 to 400 nanometers in sunlight, which can be divided into three types: UVA, UVB, and UVC. According to the effects of ultraviolet rays on organisms, ultraviolet rays are divided into different bands in medicine: melasma ultraviolet rays are in the 320-400 nanometer band; erythema ultraviolet rays or health rays are in the 280-320 nanometer band; sterilization ultraviolet rays are in the 200-280 nanometer band; ozone-causing ultraviolet rays are in the 180-200 nanometer band.

[0003] The square cotton machine ultraviolet sterilizer uses the C-band ultraviolet sterilization effect. C-wave ultraviolet rays are extremely destructive to microorganisms. When the ultraviolet rays in this band irradiate the bacteria, the nucleoprotein and deoxyribonucleic acid of the cells strongly absorb the energy of this band, and the chains between them are opened and broken, thus killing the bacteria.

[0004] Ultraviolet light has the following defects in the prior art, especially in the disinfection application of square cotton pad machines:

[0005] In 1982, Canada invented the world's first open channel ultraviolet disinfection system. After that, ultraviolet sterilization was widely used in water treatment, food and space disinfection. Most of these applications require long-term exposure and have low efficiency. The excessive concentration of ozone produced can cause certain harm to the human body. Therefore, in production, although the cost of ultraviolet lamps is low, the cost of personnel protection and equipment setting on the production line is higher, resulting in less use of ultraviolet sterilization equipment on daily necessities production lines.
