Efficient paper conveying device used for bag package mechanical production equipment

Abstract

The invention discloses an efficient paper conveying device used for bag package mechanical production equipment. The efficient paper conveying device comprises a paper film changing mechanism and a swing shaft roller tensioning and alarming mechanism, wherein the paper film changing mechanism is arranged at the bottom of a paper supporting frame, and the swing shaft roller tensioning and alarmingmechanism is arranged in the middle of the paper supporting frame. Two horizontal plates are fixed to the top of the paper supporting frame. A coding position adjustment mechanism is arranged betweenthe two horizontal plates. Tracking optoelectronic switch position adjustment mechanisms are arranged on the two horizontal plates. A film damping mechanism is arranged at the rear end of the top ofthe paper supporting frame. A paper film deviation rectifying mechanism is also arranged on the paper supporting frame. In the paper conveying process, a roll paper film driving motor continuously operates in small-fluctuation and speed-variation modes, so that a swing arm of a swing shaft roller of the paper conveying device is kept swinging by a small angle within a small range, and the rotatingspeed of the roll paper film driving motor is automatically matched with the paper consuming speed of a packaging machine in the continuous operating process; and when the movement range is too largeand exceeds a set value, an encoder feeds a signal back to a control system to achieve automatic halts, an alarm is given when no film is available or when film supply is abnormal, and thus, continuous and stable tension is provided for a paper supply system.

Description

technical field [0001] The invention relates to a packaging machine, and more specifically, the invention relates to an efficient and intelligent paper feeding mechanism used in equipment for bagged food or medicine packaging machinery production. Background technique [0002] In the existing packaging production machinery and equipment, the paper feed motor that drives the paper roll rotation in the paper feed mechanism is in use. The motor runs when the paper is fed, and when the paper roll stops, the motor stops. This paper roll drive The intermittent working mode of the motor, due to the interference of various factors such as inertial buffering effect, paper film material and plastic deformation, different surface roughness of the paper film, and different pretension force of the paper film, also means that the speed of the motor must be consistent with the mechanism. The running speed should be highly matched at all times. Otherwise, the tension of the paper feeding me...

Problems solved by technology

After the paper film passes through each roller shaft, the transmission distance is longer, and each component is limited by processing accuracy, assembly accuracy and other processing factors. If you want to improve the accuracy to correct the problem of deviation, it will undoubtedly cause a huge increase in manufacturing costs. greater expenditure

At present, the paper feeding mechanism of most packaging machines in the market is widely used to correct the deviation of the paper film by adjusting the position of the paper roll. This correction method will not only cause too much waste of the packaging paper film, but also time-consuming and laborious to operate.

On the other hand, when replacing the paper film and continuing to connect the paper film, the operation process is complicated, and it is necessary to reset and adjust the tension of the system. It takes too much time to adjust the coding position of the coding machine and the position of the photoelectric sensor. It also caused great inconvenience to production and maintenance
