Tobacco tow density adjusting device

Abstract

The invention discloses a cigarette tow density adjusting device, and belongs to the field of cigarette equipment in the cigarette industry. The device comprises a compaction wheel, an adjusting assembly and a fixing support, the adjusting assembly comprises a connecting frame, an adjusting shaft, a spring and an adjusting wheel, the compaction wheel is rotatably mounted at the upper end of the connecting frame, the fixing support comprises a mounting end face and a fixing end face, the fixing end face is fixedly connected with a filament suction beam fixing seat, and a mounting hole is formedin the mounting end face. The adjusting shaft penetrates through the mounting hole, the upper end of the adjusting shaft is fixedly connected to the lower end of the connecting frame, the lower end of the adjusting shaft is connected with the adjusting wheel, and the spring sleeves the adjusting shaft and is supported between the lower end of the connecting frame and the mounting end face. According to the device, the gram weight deviation of a single cigarette is reduced, the empty end rejection rate of the cigarette is reduced, meanwhile, the residual cigarette amount is reduced, the cigarette index stability is improved, and the factory production and manufacturing level is continuously improved.

Description

technical field [0001] The invention belongs to the field of cigarette equipment in the cigarette industry, and in particular relates to a device for adjusting the density of shredded tobacco bundles. Background technique [0002] With the improvement of consumers' requirements for the sensory quality of cigarettes, the simple pursuit of cigarette appearance quality in the past can no longer meet the needs of consumers, and the stability of cigarette weight directly affects the sensory quality of cigarettes. One of the important indicators of consumer sensory quality. [0003] During the cigarette forming process, the VE feeding and forming machine of the ZJ17 cigarette making machine absorbs the cut tobacco that meets the standard on the suction belt through negative pressure suction to form a tobacco bundle, and provides qualified tobacco bundles for the SE cigarette machine. During this process, the uniformity of shredded tobacco conveying, the change of negative pressur...

AI Technical Summary

Problems solved by technology

During this process, the uniformity of shredded tobacco conveying, the change of negative pressure suction, the wear of the suction ribbon and the chopper make the filling capacity of the shredded tobacco bundle change, which affects the stability of the single weight of the cigarette, making the cigarette’s The deviation of single gram weight increases, which reduces the qualified rate of single gram weight deviation of cigarettes, and at the same time, it will produce empty cigarettes

The deviation of a single gram weight of a cigarette reflects the stability of the processing accuracy and internal quality of a cigarette. The increase in the deviation of a single gram weight of a cigarette indicates that a certain degree of waste is caused in the production process of cigarettes, which affects the production of the factory. level of continuous improvement

[0004] In the existing production process, the wear of the suction belt and the chopper can be solved by replacing the accessories. The uniformity of tobacco delivery and the change of negative pressure suction are difficult to solve in the actual production process, but its influence on the forming density of tobacco bundles Larger, resulting in an increase in the up and down fluctuation of the shredded tobacco bundle after being trimmed by a chopper, directly resulting in an increase in the weight deviation of a single cigarette, and an increase in the rejection of overweight and ultralight cigarettes, resulting in waste of shredded tobacco and cigarette materials
