Description

Multifunctional miner lamp number stamping machine

Technical Field

The utility model belongs to mining auxiliary assembly, concretely relates to multi-functional miner's lamp scalds number device.

Background

Mine lamps are vividly called eyes of mine enterprise staff, and mine underground operation staff leave the mine lamps, so that the blind people touch the mine lamps in an intricate and complicated underground manner and are at any time in danger of accidents. Therefore, the fourth hundred seventy-five rules of coal mine safety regulations specify: the miner's lamps should be managed in a centralized and unified way. Each miner's lamp must be numbered, and the person who often uses miner's lamps must specialize in the lamp. Within 2h of each shift, the light house personnel must report a list of no light personnel to the mine dispatch room ". In order to realize the management of special lamps for special persons who often use miner's lamps, the current common practice of coal mine enterprises is to number miner's lamps and establish a ledger management mode for the people by the numbers. For our mine, more than three thousand of the existing common mine lamps are used, and most of the existing mine lamps can only be used for about one and a half years under the current charging condition, so that the new mine lamps need to be replaced. In order to avoid the large influence caused by large-area replacement of the miner lamp, a method of replacing miner lamps in batches by stages is generally adopted, and about 2000 miner lamps need to be replaced every year, so that a large number of miner lamps need to be replaced and numbered every year. The numbering methods used previously are: the electric furnace wire heats the character and number and the rubber matrix manually dips the lacquer to print the number. The electric furnace heating type and size stamping method comprises the following steps: the problems of electric shock, scald, fire accident, uncontrollable heating temperature, easy damage to the miner lamp, low working efficiency and the like are easy to occur. The mode of dipping the rubber matrix into the lacquer and printing the number has the following problems: firstly, the preparation time for finding and mixing paint is long; secondly, the paint is mixed with the thick and thin paint, so that the influence on the printing definition is large; thirdly, the printed miner lamp needs a certain drying time, otherwise the miner lamp is easy to wipe off; fourthly, the work site is easy to be polluted; fifthly, the problems that the time for dipping the lacquer printing is long, the lacquer printing is easy to be worn and dirty and cannot be seen clearly, and the like are solved.

In view of the above reasons, the multifunctional miner lamp number ironing machine manufactured by the factory has good effect after use experiments and is deeply praised by the staff.
