Description

Technical Field

[0001] The invention relates to the technical field of tobacco industry silk making equipment, and in particular to a novel moisturizing cover plate device for a tobacco belt conveyor. Background Art

[0002] Belt conveyor is a device for continuously transporting tobacco materials on the silk-making line in the tobacco industry. It is suitable for the transportation of tobacco materials such as tobacco leaves and leaf shreds, and is an auxiliary connection device between the main machines. Belt conveyor is mainly composed of head device, tail device, fuselage section, active roller, passive roller, roller, cleaning device, conveyor belt, discharge port, blanking frame and driving device. It is a continuous conveying mechanical equipment with flexible conveyor belt as material carrier and traction part. The belt moves continuously, so that the material can be transported according to the predetermined process, realizing long-distance and large-flow material transportation. The material is transported in an open material trough composed of conveyor belt and two side wall panels. Affected by the season, weather and the production environment, the moisture of the material is easy to be lost during the transportation process. The moisture of the material entering the next drying process is prone to fluctuations and process deviations, which has a certain impact on the feed moisture stability of the next material drying process, thereby increasing the deviation value of the moisture at the material drying outlet. With the improvement of process control and deviation accuracy requirements, the level of moisture deviation control in the material transportation process needs to be improved.

[0003] At present, the width of the belt conveyor for silk thread making is mostly 800-1000mm, and the height of the operating platform from the conveyor belt is about 500mm. At the end of each batch of production, the residual materials on the belt conveyor need to be blown clean. Usually, a conventional hinged cover is set on the body of the belt conveyor, and the opening angle needs to be greater than 90°. Due to the limitation of the operating distance, tools need to be used, or the operator needs to climb onto the body of the belt conveyor to operate the opening and closing of the cover. The operation is time-consuming and labor-intensive, and there are safety hazards. Summary of the invention

[0004] The purpose of the present invention is to overcome the deficiencies in the prior art and to provide a new type of moisturizing cover device for a tobacco belt conveyor. The cover device is designed with the strength, safety and reduction of the labor intensity of operators in mind. It has high safety, focuses on reducing the labor intensity of operators, improves the working efficiency of the equipment, and ensures the safety and stability of the operating site.
