Lead air drying machine

Abstract

The invention discloses a lead air drying machine. The lead air drying machine comprises a rotating roller arranged in a box body; the roller is provided with a synchronous belt; a condenser and a draught fan of an air source heat pump are arranged in a heating cavity of the box body; an air drying cavity is provided with the roller; the heating cavity is divided into an inner cavity body and an outer cavity body; the roller is provided with a lead inlet and a lead outlet; the roller is divided into a shape finalizing area and a swaying area in the axial direction; the side wall of the portion, with the shape finalizing area, of the roller is in a closed state; a plurality of through holes are distributed in the side wall of the portion, with the swaying area, of the roller; the air dryingcavity except the roller communicates with the outer cavity body of the heating cavity through a screen net. According to the lead air drying machine, directing at roller air drying of fireworks leads, a reasonable and effective circulating air duct is constructed, and a safe and reliable lead air drying mode is built; fast and efficient drying of the leads is achieved in two steps of shape finalizing and blowing drying, the continuous and reliable process that the leads are wound on the roller is guaranteed, and the lead drying quality is guaranteed.

Description

technical field [0001] The invention relates to an air-drying device for lead wires for fireworks and firecrackers. Background technique [0002] The Chinese utility model patent document whose notification number is CN206014721U discloses "a kind of wet-process lead wire air-drying unit", which includes a pay-off rack on which several lead wire groups can be suspended; an air-dry box body is provided with a lead wire inlet and a lead wire outlet, and the A drum is arranged in the air-drying box, and a shaft roller is arranged in the center of the drum, and bearing seats are fixed at both ends of the shaft roller on the shell of the air-drying box, so that the drum and the shaft roller can perform concentric rotary motion; Machines for harvesting air-dried leads into finished lead coils. The unit adopts the structure of the gear set acceleration and deceleration machine to realize the air-drying process of the lead wire moving smoothly from one end to the other end in the b...

AI Technical Summary

Problems solved by technology

[0003] However, there is still room for optimization and improvement in the mechanism settings such as the circulating air duct of the equipment, and there are problems such as low air-drying efficiency and high energy consumption.
