Compressing device for tobacco stem compressing machine scrapers

Abstract

The invention discloses a compressing device for tobacco stem compressing machine scrapers. A tobacco stem compressing machine comprises a movable roller and a fixed roller and is characterized in that a scraper component is arranged below each of the movable roller and the fixed roller, each scraper component comprises a scraper, a scraper mounting plate and a lever arm, each lever arm is connected to lower end of the corresponding scraper mounting plate, a corresponding counter weight is arranged at the outer end of each lever arm, each counter weight comprises an air cylinder, the body of each air cylinder is hinged to a frame, the piston rod of each air cylinder extends out upwardly and is connected with a flexible hanging rope, the upper end of each hanging rope is connected to the outer end of the corresponding lever arm, each air cylinder is connected with a compressed air source through an air channel, each air channel is provided with a filtering reducing valve and a manual reversing valve, and the telescoping of the piston rods of the air cylinders is controlled through the manual reversing valves to compress and release corresponding scrapers; the air supply pressure of the air cylinders is automatically adjusted through the filtering reducing valves to regulate the compressing force of the scrapers. The compressing device is simple and convenient to operate and capable of optionally adjusting the compressing force of the scrapers in a certain range.

Description

technical field [0001] The invention relates to the technical field of tobacco material processing equipment, in particular to a scraper pressing device for a stem pressing machine. Background technique [0002] Existing stem pressing machines include a frame on which horizontal moving rollers and fixed rollers are arranged side by side. A tobacco stem rolling channel for the passage of tobacco stems is formed between the moving rollers and the fixed rollers. It is provided with its own scraper assembly, each scraper assembly includes a scraper and a lever arm, and the outer end of the lever arm is provided with a weight group as a counterweight, see figure 1 , each weight group is composed of two weights of different sizes, the larger weight is the first weight 19, and the smaller weight is the second weight 20, the scraper is pressed towards the Roller. By loosening the screw 21, the second, smaller weight 20 can be removed, whereby a different pressing force can be prod...

AI Technical Summary

Problems solved by technology

According to maintenance requirements, the counterweight needs to be removed, and the weight of the first weight 19 is 12.5Kg, the weight of the second weight 20 is 3Kg, and the total weight of the two weights is 15.5Kg. The installation location is not conducive to manual removal of weights, the operation is very inconvenient, time-consuming and laborious
