Device and method for adjusting angle of upper row chain of tobacco cutting machine

Abstract

The invention provides a device for adjusting an angle of an upper row chain of a tobacco cutting machine. Row chains are arranged on a wall plate, an upper row chain is arranged on a front shaft anda rear shaft, a limiting groove is formed in the wall plate, and a cylinder is arranged at a shaft end of the front shaft; and two ends of the rear shaft are separately connected with swing arms, theother end of the left swing arm is connected with an adjusting arm via a pin, the other end of the adjusting arm is connected with an indexing device, the other end of the right swing arm is connectedwith a driven adjusting arm, the other end of the driven adjusting arm is connected with a fulcrum shaft, the other end of the fulcrum shaft is connected to a fulcrum shaft seat, and the fulcrum shaft seat is connected with a right wall plate. The adjusting method comprises the following steps: forming three crank and rocker mechanisms via the upper row chain, the swing arms, the adjusting arm, the wall plate and the limiting groove, rotating a motor according to commands, driving the adjusting arm to move, driving the rear shaft to move by the swing arms, and changing an included angle formed between the upper row chain and the horizontal plane. The device is reasonable in design, simple in structure, safe and reliable, convenient to adjust and easy to manufacture; the included angle between the upper row chain and the horizontal plane can be adjusted conveniently and rapidly; and various using requirements are met.

Description

technical field [0001] The invention relates to a device and a method for adjusting the upper chain of a tobacco cutting machine, in particular to a device and a method for adjusting the angle of the upper chain of a tobacco cutting machine. Background technique [0002] The shredding machine is the shredding equipment on the shred production line of the tobacco factory. Its function is to gradually compact the processed tobacco leaves into a certain density of "smoke cake" under the linkage of the upper and lower chains and transport them to the knife door. The tobacco cake layer is cut into shredded tobacco that meets the technical standards by the blades on the cutter roll. Due to the different organization and structure of materials, different compression ratios are required, which determines that the wedge angles of the upper and lower chains are different. Under normal circumstances, according to the different materials to be cut, the shredding machine is divided into...

AI Technical Summary

Problems solved by technology

The structure of the upper chain has developed from the early parallel four-bar linkage mechanism to today's crank rocker mechanism. The upper chain in the form of a parallel four-bar linkage mechanism maintains a fixed angle with the horizontal plane in real time during the action process. Constant compression ratio and transmission speed, but its structure is complex, difficult to manufacture and maintain, and high cost. The upper chain structure in the form of a single crank rocker mechanism is different from the horizontal plane during the action due to the different positions of the swing rod in the working state. Forming a changing angle, due to the existence of this changing angle, the transmission speed and compression ratio of the upper chain will change, thus affecting the quality of silk production

The shredding machine requires different chain transmission speeds and different compaction ratios in the process of equipment experimentation, debugging, and use. Especially in the new machine experiment and debugging stages, for the accumulation of errors in parts manufacturing, assembly, etc., existing equipment It is difficult to adjust the mechanical structure of the upper chain, even if it can be adjusted, the adjustable range is very limited
