A kind of preparation method and production equipment of fireworks barrel

Abstract

The invention discloses a firework cylinder manufacturing method and production equipment. The firework cylinder manufacturing method is characterized by including the following steps that a, raw materials are manufactured, wherein the raw materials include plant fibers, padding and a setting and hardening material, and the setting and hardening material is an air hardening cementing material or a water hardening cementing material or a mixture of the air hardening cementing material and the water hardening cementing material; b, the raw materials are put into a forming mould; c, high-frequency vibration is applied to the raw materials in the forming mould through 20KHZ-50KHZ ultrasonic waves, at the same time, an upper mould body and a lower mould body of the forming mould are matched and exert 2t-8t pressure to extrude the raw materials, and the raw materials are extruded into a firework cylinder basic finished product; d, the firework cylinder basic finished product is taken out from the forming mould. The firework cylinder manufacturing method shortens the forming time of the raw materials in the mould, improves demoulding quality, reduces the content of moisture, shortens later drying time, shortens a production cycle of the product, and improves production efficiency of the product.

Description

technical field [0001] The invention relates to a preparation method and production equipment of a fireworks cylinder. Background technique [0002] Traditional fireworks outer cylinders are mainly made by hand, and the main raw material is paper. Its production method is: paper cutting, gluing, roller, trimming, drying, bundling, sealing, drilling, inserting lead wires, etc. At present, this traditional production method is still the most important production method of the outer tube of fireworks. The disadvantages of the above methods are that there are many processes, low processing efficiency, long production time, and a large amount of paper and glue are consumed. [0003] In order to overcome the inefficiency of traditional fireworks outer tubes, many new manufacturing methods have been developed by people in the industry: [0004] The application number is: 200710034745.X, and the patent name is: A Chinese patent application for a shell of fireworks, which disclose...

AI Technical Summary

Problems solved by technology

However, in the process of using this equipment for production, since the vibrating plate is used to drive the core fixing frame to vibrate, thereby realizing the vibration of the raw materials in the core fixing frame, frequent mechanical vibrations have a great impact on the accuracy of the equipment, and the wear of the mold is relatively large. Severe, affecting the demoulding of the mold and the service life of the mold

Due to the mixed moisture in the raw materials, it takes a long time for extrusion and setting before the fireworks cylinder is released from the mold, so as to ensure the firmness before the mold, so as to ensure the successful demoulding of the product, and it takes a long time to dry the product after the mold is released , so the whole production process takes a long time
