Description

Technical Field

[0001] The utility model relates to the field related to firecracker charge production, in particular to an intelligent timing control device for firecracker charge production. Background Art

[0002] Among the main raw materials of firecrackers, potassium sulfate and sulfur have relatively large particles when leaving the factory, and are easy to form lumps when the air is humid. The drug mixing device in the charging machine has relatively high precision, and the risk factor of drug mixing is relatively high. If the drug material is not fine enough, it is easy to cause blockage of the feed port, which is dangerous. In addition, the drug particles are too large to exert their maximum performance. Therefore, the charging workshop generally needs to crush these two materials before loading, and the crushing time directly affects the degree of crushing of the drug material. The crushing time needs to be controlled by an intelligent timing control device. A timing device is set at the drug material crusher. The staff in the crushing room sets the working time of the machine through the regulator. After the setting is completed, the machine is controlled to stop running through the AC contactor. This can avoid the problem of insufficient crushing due to poor control of time by the staff responsible for drug crushing.

[0003] However, the existing intelligent timing control device needs to open or close the door frequently. After the door is opened, the dust in the crushing room will enter it and accumulate at the connection of the wires for a long time. If it is not cleaned in time, a complete power-on circuit may be formed between the two levels of the power supply, thus forming "contaminated conduction". This abnormal "contaminated conduction" will not only lead to poor contact of the wires, but may even cause fire. Utility Model Content
