Fed paper cutting position adjustment and compensation device of packing machine

Abstract

The invention discloses a fed paper cutting position adjustment and compensation device of a packing machine. The device comprises a power input shaft, an input gear fixedly connected with the power input shaft and a power output shaft, wherein the input gear is engaged with a planetary gear mechanism on the power output shaft, and a rotary arm in the planetary gear mechanism is connected with a velocity compensation and locking mechanism to form a differential gear transmission structure. The planetary gear mechanism is used as a compensation device, and a compensation displacement angle is superposed to the power output shaft in a mode of superposing a compensation velocity and a main shaft feeding velocity, so fed paper cutting position adjustment and compensation are realized and can be performed in a main shaft clearance or continuous paper feeding; and the device has the advantages of high precision, high compensation velocity and capability of automatically judging the compensation direction according to the main shaft feeding condition to perform positive or negative compensation, meanwhile, has pre-adjusting function, can track color codes after first startup or packing material change, and has high product qualification rate.

Description

technical field [0001] The invention relates to a position adjustment device, in particular to an adjustment device in a packaging material color mark tracking system of a packaging machine. Background technique [0002] The packaging material cutting position adjustment device in the color mark tracking system of the packaging machine is mainly used to adjust and compensate the error of the packaging machine's cutting position. At present, our company's original tongue depressor packaging machinery is equipped with a color mark tracking system, and its packaging material cutting position The method of adjustment and compensation is generally adopted: detect the color mark on the continuously fed packaging material, and electronically adjust the spindle speed to track the color mark on the packaging material, so as to achieve the purpose of adjusting and compensating the cutting position error of the packaging machine . The disadvantages of this tracking method are: because...

AI Technical Summary

Problems solved by technology

The disadvantages of this tracking method are: because the feeding speed of the main shaft needs to be adjusted to indirectly track the color mark on the packaging material, the cutting position always swings back and forth between the color mark, the tracking accuracy is not high, and the system response speed is not fast, which affects the packaging speed of the whole machine. After starting up or changing packaging materials, it takes a certain period of time to track the color mark, resulting in a certain number of waste products
