High-speed printer for cables

Abstract

The invention discloses a high-speed printer for cables. The high-speed printer for the cables comprises a frame, an ink supply device, a printing mechanism and an inkjet component, wherein the ink supply device, the printing mechanism and the inkjet component are supported on the frame. The ink supply device is communicated with an ink delivery hole of the inkjet component, an ink nozzle of the inkjet component is adjacent to a printing wheel of the printing mechanism, the printing wheel of the printing mechanism is driven by an adjustable-speed motor, a swing arm pressure regulating device is connected to a pressing wheel support arm of the printing mechanism, and a pressing wheel is in driving connection with an encoder. The ink nozzle of the inkjet component is fixedly connected to a nozzle shaft, the ink delivery hole is formed in the nozzle shaft, a printing wheel support seat is connected to a nozzle shaft support seat, and the ink supply device is provided with an ink viscosity regulating device. The high-speed printer for the cables has the advantages that the high-speed printer is capable of guaranteeing operating synchronism of the printing wheel and the cables and pressure stability of the pressing wheel, controlling ink viscosity difference and improving ink cleanliness; meanwhile, a nozzle component is succinct and compact in structure, so that high-speed printing for the cables can be guaranteed.

[0002] With the advancement of technology, the production speed of cable production equipment has been greatly improved. As one of the links in the cable production process, the cable printer must adapt to it, but the commonly used cable printers are often unable to adapt to high speed. The production requirements are mainly due to the difficulty in guaranteeing the quality of printing under high-speed production conditions, and there are often phenomena such as low clarity of printing content and missing printing. The reasons involve printing pressure, synchronization of printing wheels and cables, and ink supply, etc. On the one hand, the unstable printing pressure will not only lead to heavy or light printing color, and even missing printing, but also cause changes in the friction between the printing wheel and the cable, making the movement between the printing wheel and the cable asynchronous, resulting in The printing is blurred, and the printing wheel relies on the friction between the cable and the operation. Under high speed conditions, especially at the stage of starting and stopping the equipment, due to the inertia of the printing wheel, the surface line speed of the printing wheel is different from that of the cable. The difference between the speeds is particularly obvious, and the printing quality is difficult to guarantee; in terms of ink supply, on the one hand, the solvent in the supplied ink will gradually volatilize during use, making the ink thicker, and the viscosity difference of the ink will lead to poor printing quality. Changes; on the other hand, due to the friction between the printing wheel and related objects such as cables and scrapers during use, there will be powder impurities. These powder impurities are mixed in the ink, which will also affect the printing quality; in addition , the installation structure between the ink nozzle and the ink connection pipeline and the ink nozzle support is relatively complicated, the operation, use and maintenance are very inconvenient, and there are many fault points, and the ink supply pipeline of the ink nozzle is located in the inkjet area of ​​the printing wheel, both It is not beautiful, and it is not convenient to close the inkjet area. It is easy to cause ink leakage and affect the surrounding environment. It needs to be cleaned frequently. It is also one of the factors that cause the cable printer to not adapt to high-speed operation.
