Description

Technical Field

[0001] The utility model relates to the technical field of tobacco leaf redrying machinery, in particular to an adjustable automatic spray cleaning device for a tobacco leaf redrying machine. Background Art

[0002] The tobacco slice redrying machine is mainly used for the redrying process of drying, cooling and rehumidifying tobacco slices. Its side chain is a mesh belt drive transmission component of the tobacco slice redrying machine, which is composed of rollers, fixed pins, latches, left plates and right plates. During the operation of the side chain, impurities such as tobacco oil and dust will adhere to the surface of the side chain side plates, and some impurities will also enter the gap between the side chain rollers and the fixed pins, and the gap between the side plates. The lubricating oil cannot fully lubricate the rotating contact surface, causing the rollers and the fixed pins to wear more severely and the side plate rotation joints to be inflexible. At the same time, after the side chain runs from the rehumidification zone to the tail cooling zone, it exchanges heat with the outside world to produce condensed water, which causes the lubricating oil to be diluted, further weakening the lubrication effect. Traditional manual cleaning of the side chain cannot remove impurities and condensed water in the gaps. After long-term operation, the inner diameter of the side chain roller is enlarged, the outer diameter of the fixed pin is reduced, and the service life of the side chain is reduced.

[0003] Announcement No. CN 214441465 U discloses an automatic spray cleaning device for the side chain of a tobacco slice redrying machine, which can realize regular automatic cleaning of the side chain, eliminate the safety hazards of manual cleaning, save labor costs, effectively remove impurities and condensed water on the surface and in the gaps of the side chain, ensure good cleanliness of the side chain, and make full use of the lubricating oil to avoid multiple lubrication due to insufficient lubrication, saving the amount of lubricating oil. The air source used for spraying comes from the workshop air compressor, which is relatively low in cost. However, the patent still has the following problems in actual use:

[0004] The automatic spray cleaning device for the side chain of the tobacco redrying machine sprays through the two spray holes at the bottom of the first nozzle and the second nozzle, but since the size of the spray holes is fixed, the spray range cannot be adjusted, resulting in limited spray effect. When the number of tobacco slices transported by the side chain of the tobacco redrying machine is large, impurities such as tobacco oil and dust will also increase. When the spray range is certain, some dust and tobacco oil will enter the gap between the side chain roller and the fixed pin shaft, and the gap at the junction of the side plate, thereby causing increased wear of the roller and the fixed pin shaft and inflexible rotation joints of the side plates.

[0005] An adjustable automatic blowing and cleaning device for a tobacco strip redrying machine is proposed to solve the above-mentioned problems. Utility Model Content
