Description

Technical Field

[0001] The present invention relates to the technical field of paper tube drying, and particularly to a paper tube drying device for combined fireworks production. Background Art

[0002] Fireworks, also known as flower bombs, fireworks, pyrotechnics, and firecrackers, are defined in the "Chinese Standard for Fireworks and Firecrackers - Safety and Quality" as entertainment products made of pyrotechnic compositions for producing sound, light, and color. Invented earlier by the Chinese working people, they are often used in grand ceremonies or performances. In fact, the structure of fireworks is similar to that of firecrackers, both of which contain black powder and fuses. To achieve good performance effects, a large amount of gunpowder for launching and exploding is filled in fireworks and salute shells. For example, after a salute shell with a diameter of 20 cm is launched, it will rise to an altitude of about 200 m before exploding, and the radius covered by these scattered points can be about 80 m.

[0003] During the production process of the paper tubes of fireworks, they contain a relatively large amount of moisture and need to be dried using a drying device. During the drying process, water vapor is generated. Most of the existing drying devices directly discharge the water vapor into the air. However, during the discharge process, the water vapor will carry away some heat, resulting in a large amount of heat loss and waste.

[0004] In view of the above problems, we propose a paper tube drying device for combined fireworks production. Summary of the Invention

[0005] The purpose of the present invention is to solve the defect in the prior art that "most of the existing drying devices directly discharge the water vapor into the air. However, during the discharge process, the water vapor will carry away some heat, resulting in a large amount of heat loss and waste", and thus propose a paper tube drying device for combined fireworks production.

[0006] To achieve the above purpose, the present invention adopts the following technical solutions: A drying device for paper tubes used in the production of combined fireworks, comprising a working box and a rolling mechanism. A reduction motor is fixedly connected to the left side of the working box.

Two large gears are symmetrically and fixedly sleeved on the reciprocating lead screw. A small gear is meshed with each large gear. A cross bar is horizontally and fixedly inserted through the centers of the two small gears. Two first helical gears are symmetrically and fixedly connected to the cross bar. A second helical gear is meshed with each first helical gear. A vertical rod is fixedly connected to the upper end of each second helical gear. A transfer box and two fixed boxes are fixedly connected to the upper end of the working box. The upper end of each vertical rod penetrates through the side walls of the working box and the fixed box and is fixedly connected to a first bevel gear. A second bevel gear is meshed with each first bevel gear. A connecting rod is horizontally and fixedly inserted through the center of each second bevel gear. One-way blades are fixedly connected to the opposite ends of the two connecting rods. Connecting pipes are fixedly connected to the opposite sides of the two fixed boxes. The opposite ends of the two connecting pipes are both communicated with the transfer box. A plurality of metal plates and heating wires are respectively and fixedly connected to the inner walls of the two connecting pipes. A liquid storage tank is fixedly connected to the lower end of the left connecting pipe. Each fixed box is communicated with the inside of the working box through a nozzle.

A paper tube is arranged in each groove. A cavity is formed in the fixing block. An electric heating plate is fixedly connected to the inner wall of the cavity.

[0009] Preferably, a plurality of heat dissipation fins are fixedly installed at equal intervals on the inner wall of the connecting pipe. The upper ends of the plurality of metal plates are fixedly connected to the heat dissipation fins. The liquid storage tank is communicated with the connecting pipe through a plurality of through holes.

[0010] Preferably, an electric heater is fixedly connected to the upper end of the right connecting pipe. A plurality of heating wires are electrically connected to the electric heater.

When the air passes through the metal plate, the water vapor in the air is liquefied and drips into the liquid storage tank. When the air passes through the heating wire, it is heated and then blown into the working box to increase the temperature in the working box, thereby improving the drying effect on the paper tube. Moreover, the water vapor is not directly discharged to the outside, which can reduce heat loss and avoid wasting a large amount of heat. Description of the Drawings
