Description

Technical Field

[0001] The present invention relates to a fireworks production device and method, in particular to a drug adding device and a drug adding method for a multi-group quantitative hole template. Background Art

[0002] In the production of fireworks paper tube powder, the powder is first added to the quantitative hole template, and then the movable bottom plate under the quantitative hole template is pulled to align the corresponding holes of the movable bottom plate with the quantitative holes of the quantitative hole template. The powder flows into the paper tube under the movable bottom plate. Many of these operations are performed manually, which has low production efficiency. The amount of powder added to the quantitative holes cannot be guaranteed to be consistent, and there are safety hazards. Summary of the Invention

[0006] The center line of the long brush is an S-shaped curve composed of one involute and another involute.

[0007] A drug adding method for a drug adding device with multiple groups of quantitative hole templates, comprising the following steps: (1) The conveyor belt delivers the medicine to the medicine hopper. (2) The drug hopper rotates 1-5 times to add the drug to the quantitative holes of the multiple quantitative hole templates. (3) Rotate the medicine hopper in the opposite direction 1-5 times.

[0008] Compared with the prior art, the advantages of the present invention are simple structure, high reliability, greatly improved product quality and quantity, reduced labor intensity of operators, and eliminated safety hazards. BRIEF DESCRIPTION OF THE DRAWINGS
