Abstract

The invention discloses a device for manufacturing a safe fireworks fuse, which comprises a powder hopper arranged on a rack, a weaving mechanism, a coiling mechanism and a driving and transmitting mechanism. The device is characterized in that the discharging hole of the power hopper is connected with a powder applying pressure tank via a screw rod powder-extruding cylinder, the upper end surface of the powder applying pressure tank is provided with at least one line hole, the corresponding position at the lower end surface is provided with at least one line hole, and a screw rod of the screw rod powder-extruding cylinder is connected with the driving and transmitting mechanism. According to the device, the requirements on a wet processing technology for manufacturing the fuse can be satisfied, the consistent specification of a product is realized, the powder density of the fuse is substantially strengthened, higher uniformity and stable burning rate are realized, and the occurrence of a cutoff phenomenon can be completely stopped. The device has the advantages of high automation degree, coordination in system operation and higher production efficiency. Moreover, all performance data of the fuse product meet or exceed the requirements on the national standard, and the storage time of the fuse product is prolonged by more than four years compared with the original product.

Description

technical field [0001] The invention relates to a fuse for fireworks and firecrackers, in particular to a production device for a safety fuse for fireworks. Background technique [0002] Firework fuse is a pyrotechnic product used to ignite, spread fire, and control time. According to the material of the outer wrapping layer, it can be divided into yarn paper fuse, safety fuse and kraft paper quick fuse. There are big differences in the production methods of various fuses. In the present fireworks production, the use of safety fuse is more and more, and safety fuse is to take pyrotechnic powder as medicine core, makes wrapping thing with cotton thread, is woven into outer weaving layer, is coated with the fuse of moisture-proof material. It is characterized by good moisture-proof and mildew-proof performance, high tensile strength, firmness and toughness, can burn in water, and is difficult to ignite from the side of the fuse. [0003] The traditional production method of ...
