Paper feeding device convenient to quickly switch and used for carton production

Abstract

The invention discloses a carton production paper supply device convenient for fast switching, which comprises a base and a U-shaped frame arranged above the base, a rotating plate is rotatably arranged in the middle of the U-shaped frame, and the two ends of the rotating plate are respectively provided with a driving shaft for mounting a winding roller; the driving shaft is provided with a positioning assembly used for fixing the winding roller. The middle position of the rotating plate is connected with a switching fixing shaft, the switching fixing shaft is connected with a switching driving part used for driving the switching fixing shaft to turn over so as to achieve switching of the standby winding roller, and a conveying part used for transferring the winding roller is arranged above the base. According to the paper conveying device, winding rollers for providing paper can be rapidly switched, the machining efficiency is improved, meanwhile, when the paper is preliminarily conveyed, through negative pressure traction, the head of the paper can be rapidly found and connected in a butt joint mode, manual intervention is not needed, and safety and practicability are high.

Description

technical field [0001] The invention relates to the technical field of carton processing equipment, in particular to a paper supply device for carton production that is convenient for quick switching. Background technique [0002] Carton is a low-cost, high-quality disposable or reusable packaging product. The cardboard used to make cartons can be divided into corrugated cardboard, composite cardboard, single-layer cardboard, etc. according to the difference in structure and material. The hard material packaging represented by boxes has outstanding advantages such as low material cost, easy production, and convenient storage / transportation. [0003] During paper processing, it is necessary to continuously fold and thicken the base paper, so that the paper has a certain rigidity. Under the action of the paper supply roller, the paper is continuously supplied from the winding roller. When the paper on a single winding roller is used up, It is necessary to replace a new windin...

AI Technical Summary

Problems solved by technology

[0003] During paper processing, it is necessary to continuously fold and thicken the base paper, so that the paper has a certain rigidity. Under the action of the paper supply roller, the paper is continuously supplied from the winding roller. When the paper on a single winding roller is used up, It is necessary to replace a new winding roller for feeding, which will cause the feeding to stop. Based on this, a paper feeding device for carton production that is convenient for quick switching is now provided
