Description

Technical Field

[0001] This invention relates to the field of decorative paper printing technology, and more specifically to a decorative paper post-printing collection device and system. Background Technology

[0002] Decorative paper is used to wrap the outer surface of objects. It is produced by printing technology. In existing printing machines, the decorative paper is drawn from the printing section and then glued to a paper tube at one end. This results in a section of decorative paper being discarded during use, which is a waste of resources. When the collection point is full, it needs to be replaced with another collection point. During this process, the decorative paper is cut, creating a new end waiting to be drawn and the previously collected tail light strip being collected. After collection and sealing, the head needs to be cut off. If the head is not fixed, the decorative paper is prone to curling and creases, affecting its use.

[0003] Existing control system technologies are not convenient for identifying the static electricity carried by the decorative paper after it comes out of the printing section, nor for judging the content of static electricity, nor for controlling the fixation of the beginning and end of the decorative paper during collection. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the primary objective of this invention is to provide a decorative paper post-printing collection device. This device uses an electrostatic determination unit to assess the type and amount of static electricity carried by the decorative paper after it exits the printing section of the printing press. It then replenishes or eliminates static electricity on the decorative paper and releases a certain amount of static electricity to the paper winding section. This causes the head of the decorative paper to be attracted to the winding section, reducing waste. Furthermore, a paper winding auxiliary unit collects the static electricity released from the tail of the decorative paper, allowing it to be shaped and fixed onto the rolled-up decorative paper. This utilizes the characteristic of decorative paper easily carrying static electricity, facilitating collection and avoiding head waste and tail curling / creases.

[0005] The second objective of this invention is to provide a collection system for a decorative paper printing collection device. By utilizing an electrostatic quantity detection module to determine the amount of static electricity carried by the decorative paper and the amount of static electricity released on the paper roll section, stability is ensured, while avoiding damage to the machine from excessive static electricity. In conjunction with an electrostatic quantity charging and discharging module, the amount of static electricity in the paper roll section and the paper roll auxiliary section is controlled in a unified manner, facilitating centralized handling of problems. At the same time, the collection of the beginning and end of the decorative paper is more convenient.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a decorative paper printing and collection device, comprising a support frame, a pair of paper-rolling auxiliary parts, at least one paper-rolling part, and an electrostatic determination group; the paper-rolling part is disposed on the support frame for rolling up the decorative paper; the pair of paper-rolling auxiliary parts are disposed on the support frame and located on both sides of the paper-rolling part for assisting in tightening the ends of the decorative paper after it has been cut; the electrostatic determination group is disposed on the support frame to detect whether the decorative paper carries static electricity before it contacts the paper-rolling part, to release static electricity after the decorative paper contacts the paper-rolling part, guiding the initial end of the decorative paper to adhere to the paper-rolling part; and to release static electricity to the end of the decorative paper when the paper-rolling part reaches its limit, guiding the decorative paper to adhere to the paper-rolling part. The end of the paper adheres to the remaining decorative paper. The electrostatic determination group judges the type and amount of static electricity carried by the decorative paper after it comes out of the printing section of the printing press. Then, it replenishes or eliminates the static electricity on the decorative paper. Then, a certain amount of static electricity is released to the paper winding section, so that the head of the decorative paper will act as an adsorbent, and the decorative paper can be adsorbed onto the paper winding section, reducing waste. In addition, the paper winding auxiliary section collects the static electricity released from the tail of the decorative paper, and then the tail can be shaped onto the rolled decorative paper. This utilizes the characteristic that decorative paper easily carries static electricity, making it convenient to collect decorative paper and avoiding head waste and tail curling creases.

When decorative paper needs to be collected, the electrostatic discharge detection module starts and detects the electrostatic discharge of the finished decorative paper, sending out electrostatic discharge data. After receiving the electrostatic discharge data, the data inference module performs data inference and sends out a station demand signal to determine electrostatic charge / discharge. The station conversion module controls the paper roll section to start. After the paper roll section is in place, the station conversion module sends a feedback signal to the data inference module, which sends an electrostatic discharge signal. The electrostatic charge / discharge module provides electrostatic discharge to the paper roll section.
