Problems solved by technology

The use of such a traction-guiding structure in the hot air drying drum has high requirements for the strength of the lead wire. When cotton paper is used as the lead wire raw material paper, the lead wire often breaks during the movement of the drying drum, resulting in a decrease in the yield of the lead wire, and Once the lead wire is broken, it needs to be reconnected into the drying cylinder, which is time-consuming and laborious, which greatly reduces the drying efficiency; even if the lead wire is not completely broken, after the lead wire is stretched to a certain extent, the overall strength of the lead wire is reduced, and the quality of the lead wire is affected.

Embodiment 1

[0059] Such as figure 1 and 2 As shown, the drying cylinder of the present invention includes a cylinder body 5, an inner ring frame 20, a turbine worm 4, a transport belt 7, a pulley 22, a hot air dispersion pipe 6, and a hot air blower 8; the worm 4a is fixed On the bottom surface 5a of the cylinder, a plurality of turbines 4c surround the outer circumference of the worm 4a, and the gears of the worms 4c mesh with the outer helical wire 4b of the worm; since the worm 4a is fixed, each turbine 4c can rotate At the same time, it revolves around the worm 4a along the outer helical wire 4b of the worm; each worm has a pulley 22a coaxial with it, and the pulley 22a will rotate and revolve with the worm 4a; multiple sets of coaxial pulleys 22a and the turbine 4c are fixed on the bottom surface of the inner ring frame 20; the bottom surface of the inner ring frame 20 is circular, located in the sky above the worm rod 4a and parallel to the cylinder bottom surface 5a, the top surfa...

Embodiment 2

[0061] Such as figure 1 and 2 As shown, the structure of the sizing machine according to the present invention mainly includes the sizing box 2 , the drying cylinder described in Embodiment 1, and the winding machine 26 . In the pulp drawing machine of the present invention, the lead wire semi-finished product that has completed the nitration process is taken as the processing object, and the lead wire moves forward under the traction of the winding machine 26 . The lead wire semi-finished product first enters the sizing box 2, and passes between the upper and lower rollers in the sizing box 2, enters the safety water tank 3 after completing the sizing, and then enters the drying cylinder through the drying cylinder inlet 23. In the drying cylinder, the lead wires are wound around the outer sides of a plurality of transport belts 7 on the outer cylindrical surface of the inner ring frame 20; The rotation will drive the turbine 4c fixed on the bottom surface of the inner ring...

Embodiment 3

[0065] Such as figure 1 As shown, the method for preparing a lead wire using the slurry lead machine of embodiment 2 mainly includes the following steps:

[0066] a. Place the lead wire semi-finished product that has been nitrated on the lead wire semi-finished product mounting frame 1;

[0067] b. Pull the lead semi-finished product into the sizing machine described in embodiment 2, pass through the sizing box 2, safety water tank 3, drying cylinder, humidifier 24, and safety water tank 25 successively, and finally wind on the winding machine 26 ; Use the winding machine 26 to pull the semi-finished lead wire to move forward, so that the semi-finished lead wire can be sizing, dried, and humidified in sequence, and finally the finished lead wire can be obtained;

[0068] c. Pack the lead wire finished product in step b, and store it in the finished product transfer room.

[0069] The process described in embodiment 3 and the traditional slurry drawing, sun-drying and cold-dr...

Abstract

The invention provides a drying drum which is reasonable in structure. The drying drum comprises a drum body, an inner ring support, a turbine worm, a transport belt, a belt wheel, a hot air dispersing pipe and a hot air machine. The invention further provides a starching drying device for leading wires of firework and firecrackers, namely, the starch guiding machine which is safe and reliable in operation, and high in starching and drying efficiency. The starch guiding machine mainly comprises a starching box, the drying drum, and a winding guide machine. The drying drum in the starch guiding machine adopts a turbine worm structure, can provide spiral upward drying routes for the leading wires so that the drying drum is enabled to have a reasonable volume size and provide a proper drying method for the leading wires.

Description

technical field [0001] The invention relates to an electromechanical device for sizing and drying firecracker leads. Background technique [0002] The lead wire is an important component of firecracker products, and the production of the lead wire is also an important link in the entire firecracker industry chain. Due to the flammability of the lead wire, it is also the most dangerous link in the production of firecrackers. In the traditional process, the production of lead wires is mainly made by workers by hand. However, due to low labor efficiency, great safety hazards, and unstable product quality, manual lead wires have been gradually eliminated, and even banned in many places. At present, industrial production is all about mechanical lead production, and the research and development of mechanical equipment for lead wire production has been in the ascendant. There are all-in-one manufacturing and lead machines that integrate various processes, and there are also refined...
