Description

Technical Field

[0001] The present application relates to the field of fireworks production, and more particularly, to a labeling machine for fireworks production. Background Art

[0002] Fireworks, also known as flower bombs, fireworks, pyrotechnics, and firecrackers, are defined in the "China Fireworks and Firecrackers Standards - Safety and Quality" as entertainment products made of pyrotechnic compositions for producing light, sound, and color. Invented earlier by the Chinese working people, they are often used in grand ceremonies or performances. In fact, they are similar to firecrackers, and their structures both contain black powder and fuses. After lighting the fireworks, a chemical reaction similar to the above-mentioned one is triggered, and most of the energy released during the explosion is converted into light energy and presented. By adding some luminescent agents and colorants during the production of fireworks, the fireworks can emit colorful lights. Different metal compounds emit different colors of light when burned. Sodium chloride and sodium sulfate both belong to sodium compounds, and they emit golden-yellow flames when burned. Similarly, calcium nitrate and calcium carbonate emit brick-red flames when burned. Chemically, the above results are often used to test the metals contained in substances. This type of experiment is called a flame test. Fireworks are made using this property of metals. The person making the fireworks arranges them skillfully to determine the order of burning. In this way, after the fireworks are detonated, they can bloom bright, colorful patterns in the dark sky.

[0003] The patent document with the publication number CN215554812U discloses a labeling machine for fireworks production, including an L-shaped rod, a take-up reel, a waste reel, and a label reel. When using this labeling machine for fireworks production, the label reel is sleeved on the outside of the L-shaped rod, and one side of the label reel is fitted against the first baffle. Then, the second baffle is taken and sleeved on the L-shaped rod. At the same time, the first threaded block is taken and screwed onto the end of the L-shaped rod, so that the label reel is clamped between the first baffle and the second baffle. During this process, the clamping degree of the label reel is adjusted by adjusting the first threaded block to prevent the label reel from loosening naturally when not in use. Then, the waste reel is sleeved on the take-up reel, and one side of the waste reel is fitted against the outer wall of the third baffle. At the same time, the fourth baffle is taken and sleeved on the take-up reel. Then, the second threaded block is taken and screwed onto the take-up reel, so that the third baffle and the fourth baffle clamp the waste reel, and the waste reel is fixed on the take-up reel. Although in the above-mentioned application document, the second threaded block is taken and screwed onto the take-up reel, so that the third baffle and the fourth baffle clamp the waste reel, and the waste reel is fixed on the take-up reel, the labeling speed using a hydraulic cylinder is too slow, which will directly lead to a reduction in the production volume per unit time and affect the efficiency of the overall production line.

[0022] Embodiment 1

[0023] Referring to Figures 1-4 , this embodiment provides a fireworks production labeling machine, including a fixing plate 1. A labeling device 2 is arranged on the fixing plate 1. The labeling device 2 includes a first rotating rod 21. The first rotating rod 21 is rotatably connected to the front of the fixing plate 1 through a bearing. A turntable 22 is fixedly connected to the front of the first rotating rod 21. A third movable rod 23 is hinged to the front of the turntable 22. An L-shaped rod 24 is hinged to the front of the fixing plate 1. A slider 26 is slidably connected to the outer wall of the L-shaped rod 24. An articulated rod 25 is hinged to the front of the slider 26. A connecting rod is fixedly sleeved on the outer wall of the articulated rod 25. A labeling plate 28 is fixedly connected to the bottom of the connecting rod. A motor 29 is fixedly connected to the back of the fixing plate 1. The first rotating rod 21 movably penetrates through the fixing plate 1 and extends towards the back. The extending end of the first rotating rod 21 is fixedly connected to the output end of the motor 29, which can stably carry various moving parts. The labeling device 2 is the core part of this equipment. Through the rotation of the first rotating rod 21, the labeling action is realized. The turntable 22 provides the basis for supporting the movable rod 23, and the hinged design of the movable rod 23 enables it to flexibly adjust the labeling angle as needed to ensure the accurate attachment of the label. The combined design of the L-shaped rod 24 and the slider 26 not only improves the flexibility of the device but also ensures that during the operation, the labeling plate 28 can effectively follow the movement of the object to ensure the smooth progress of the labeling process. The setting of the motor 29 enables the whole device to operate efficiently and realizes the effective transmission of power through the connection with the first rotating rod 21. A limiting block 27 is fixedly connected to the front of the fixing plate 1. The connecting rod is slidably connected to the outer wall of the limiting block 27. The design of the limiting block 27 provides important stability and accuracy for the labeling machine. By sliding the connecting rod on the outer wall of the limiting block 27, the movement range during the labeling process is controllable, avoiding possible excessive movement or misoperation. At the same time, the limiting block 27 can also prevent the labeling plate 28 from deviating during the labeling process, ensuring that the attachment position of each label is accurate.
