Embodiment 1

[0020] Mix the following ingredients (unit: kg)

[0021]

[0022] The above mixed raw materials are processed by the following steps to obtain the outer cylinder of fireworks formed by mechanized hydraulic mold at high temperature:

[0023] The first step: mixing ingredients: use a mixing machine to mix the raw materials, and then use a mixer to add an appropriate amount of normal temperature boiling water to stir;

[0024] The second step: high-temperature hydraulic mold forming: according to the first step and the prepared raw materials, pour the material into the hydraulic mold cavity of the hydraulic press with the material distribution plate, and the hydraulic press is closed. At the same time, the heat-conducting oil furnace sends the heat-conducting oil into the hydraulic press mold. Circulating heating, so that the temperature inside the mold is 120-320 degrees, until no water vapor emerges from the outside of the mold, and finally the hydraulic press opens the mold...

Abstract

The invention provides a fireworks outer barrel mechanically molded by a hydraulic mold at high temperature. The fireworks outer barrel is characterized in that the fireworks outer barrel is made of materials which include, by weight, 6-30 parts of starch, 4-50 parts of plant fibers, 20-60 parts of filling mixture, 1-12 parts of catalyst and 4-25 parts of stabilizer by the steps of mixing and high-temperature molding by the hydraulic mold. A manufacturing process of the fireworks outer barrel has high production efficiency and can realize flow-line production of the fireworks outer barrels. As compared with conventional paper outer barrels, the fireworks outer barrel need short time for drying, and especially in seasons with rainy days, the advantage in drying time is much more remarkable. In addition, the materials for making the fireworks outer barrel are degradable materials, the outer barrel of fireworks which are set off can be used as fertilizer after being degraded, and safety in setting off is guaranteed.

Description

technical field [0001] The invention belongs to a fireworks and firecracker device, in particular to an outer cylinder of fireworks and firecrackers and a manufacturing process thereof. Background technique [0002] The traditional outer cylinder of fireworks and firecrackers is mainly made of molded paper, which is rolled into a paper cylinder by a reel machine or bonded with multiple pieces of molded paper into a cardboard with a certain thickness, and then pressed by a molding machine to form an outer cylinder. Or manually rolled. This kind of traditional technology and material process is complicated, the production efficiency is low, the environment is polluted, the discharge safety accidents are frequent, the production cannot be produced in rainy days, the easy-to-explode tube is unsafe, the production cycle is long, the manufacturing cost is high, the management is cumbersome, and the demand for labor is large. Contents of the invention [0003] The invention prov...
