Printing machine for cable markers

Abstract

The invention discloses a printing machine for cable makers. Two code-spraying heads of two code-spraying machines which are oppositely arranged are arranged on the upper side and the lower side of the conveying path of the cable markers. When the cable markers are conveyed along with a conveying mechanism, the code-spraying heads which are arranged on the two sides spray and print numbers on the upper surface and the lower surface of the cable markers simultaneously, thus conveniently realizing the double-surface synchronous printing for the cable markers; the code-spraying and printing process can be thoroughly automatically and mechanically completed, thus having simple operation, convenience, high spraying and printing speed and high efficiency; simultaneously, the printing machine is especially designed for the most common and cheap PVC tubular products, thus greatly reducing the cost of consumptive material on the basis of guaranteeing the printing efficiency, and having obvious economic benefit.

Description

technical field [0001] The invention relates to a device for printing numbers on pipe materials, in particular to a printing machine for cable number pipes. technical background [0002] The cables that need to be used on ships have many specifications and large quantities, and the number of core wires used on a ship usually reaches tens of thousands. In order to facilitate the connection and maintenance of such a huge number of cables, the cables on the ship need to be uniquely numbered, and the cable number tubes are placed on the outer sheath of the cable and each terminal for identification and distinction. Moreover, several core wires of each cable have two sets of identification numbers, the cable number and the terminal number. Therefore, usually the cable numbers on board need to be made in a single way, and the core wire number tubes need to be printed on both sides. [0003] At present, there are two main ways for shipyards to print cable number tubes. One way is...

Problems solved by technology

One way is to print with a manual character code printer, which is more flexible and can be printed on the most common and low-cost PVC pipes as needed. The number tube of this material can be put back to the cable connection for protection; but The method of printing on both sides of the cable number tube by adjusting the manual character code printer one by one by the workers, the printing efficiency is extremely low

For a 300,000-ton oil tanker, there are about 50,000 number tubes, which require two workers to print continuously for about two months. The efficiency is low and the cycle is long, and it will also affect the eyesight of the printing workers.

[0004] Another way is to use a computer-controlled line number thermal automatic printing machine to print, which is easy to operate and fast in printing speed, but it cannot print on both sides at the same time

Usually, after printing a group of numbers of multiple number tubes on one side continuously, then turn over and reprint another group of numbers. In order to ensure that the front and back sides of the numbers are in the same position, it is necessary to set up and control the equipment specially, which is troublesome.

In addition, it usually prints in the way that the print head is in contact with the number tube, so flat tubes are required for printing number tubes, and tubular and low-cost tubes cannot be used

Usually, it is necessary to use heat shrinkable tubes, stickers and other special numbered pipes from manufacturers. These pipes are expensive, and a pipe usually costs a few yuan. For a ship, sometimes the numbered pipes cost tens of thousands to hundreds of thousands. , very expensive
