Description

Technical Field

[0001] The utility model relates to the technical field of fireworks production, in particular to a die-pressed combined fireworks string leading dotting device. Background Technique

[0002] The installation of leads plays a crucial role in the fireworks production process. The quality of the installation directly affects the quality of the final product. Installation errors will cause quality problems such as failed ignition and delayed ignition, and even lead to phenomena such as fireworks tipping over and gunpowder leakage, forming serious safety hazards.

[0003] A die-pressed fireworks lead-installing and dotting device with the publication number of CN107218854B bends and deforms the lead through a lead-bending die head and a lead-bending die cavity, then installs the bent and deformed lead into the lead groove of the die-pressed fireworks through a lead-pushing sleeve, and then dots and fixes the lead to achieve automated assembly line production.

[0004] The above patent still has deficiencies. When the lead-bending die head pushes the lead into the lead-bending die cavity, due to the bending of the lead, both ends of the lead will move towards the lead-bending die cavity. However, due to the large resistance at the bending point, directly using all the lead-bending die heads to push the lead easily causes the lead to be subjected to a large tensile force and break, thereby affecting the production quality of die-pressed fireworks.

[0005] In view of the above problems, an improved die-pressed combined fireworks string leading dotting device is now designed. Content of the Utility Model
