Description

Technical Field

[0001] The utility model relates to the field of fireworks production, in particular to a labeling device for fireworks production. Background Art

[0002] Fireworks are made of pyrotechnic powder and are entertainment products used to produce sound, light and color. In the production process of fireworks, in order to increase the appearance of fireworks and increase production information, manufacturers will stick notes on the fireworks to facilitate the query of fireworks production information. The labeling process of fireworks is generally completed by manual pasting, which has high labor intensity, long production time, low production efficiency, high production cost, and manual pasted labels are irregular and not firm. The labels are easy to loosen and fall off, and the product quality is difficult to guarantee. The existing labeling device is difficult to limit the fireworks with labels, which easily causes the notes to be pasted crookedly and unevenly, affecting production efficiency. Utility Model Content

[0003] In view of the defects in the prior art, the purpose of the utility model is to provide a labeling device for fireworks production which can limit the position of fireworks when labeling them, improve the labeling accuracy of fireworks, and can scrape the labels on the fireworks to make them smooth.

[0004] The technical implementation scheme of the utility model is: a labeling device for fireworks production, including a base, a bracket fixedly connected to the base, two electric rollers fixedly connected to the bracket, a conveyor belt wound between the two electric rollers, a plurality of placement grooves opened on the conveyor belt, fireworks are placed in the placement grooves of the conveyor belt, a labeling component, a limiting component and a flattening component are provided on the bracket, the labeling component is used to stick a label on the fireworks, the limiting component is used to limit the fireworks to prevent the fireworks from deviating and causing the label to be crooked, and the flattening component is used to scrape the label on the fireworks to make it flat.

[0005] Optionally, the labeling component includes a mounting frame, the mounting frame is fixedly connected to the base, the mounting frame is fixedly connected to an electric hydraulic cylinder, two rotating frames are slidably connected to the bracket, pressure springs are connected between the two rotating frames and the bracket, electric rollers are fixedly connected to the two rotating frames, a labeling roll is wound between the two electric rollers, and a pressing head is fixedly connected to the bottom of the telescopic rod of the electric hydraulic cylinder.

[0006] Optionally, the limiting component includes a limiting rod, the limiting rod is slidably connected to the bracket, a return spring is connected between the limiting rod and the bracket, a push rod is fixedly connected to the telescopic rod of the electric hydraulic cylinder, and the push rod is in contact with the limiting rod.

[0007] Optionally, the scraping component includes a transmission frame, the transmission frame is fixedly connected to the telescopic rod of the electric hydraulic cylinder, two rollers are rotatably connected to the transmission frame, and a torsion spring is connected between the two rollers.

[0008] Optionally, the pressing head is made of silicone.

[0009] Compared with the prior art, the utility model has the following advantages: 1. The extension of the telescopic rod of the electric hydraulic cylinder will drive the pressing head and the push rod to descend, and the descent of the push rod will squeeze the limit rod. The limit rod will be squeezed and move toward the direction close to the fireworks, and the reset spring will be compressed. When the limit rod contacts the fireworks and limits the fireworks, the limit rod will no longer move. In this way, the fireworks can be limited when they are labeled, thereby improving the labeling accuracy of the fireworks.

[0010] 2. When the roller descends, it will come into contact with the fireworks with labels affixed. When the roller continues to descend, it will be squeezed by the fireworks, and the two rollers will rotate away from each other. The torsion spring will be twisted, and the labels affixed to the fireworks will be scraped flat during the rotation of the roller. In this way, the labels affixed to the fireworks can be scraped flat, thereby improving the labeling quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The limiting component includes a limiting rod 11, which is slidably connected to the bracket 2, and a reset spring 12 is connected between the limiting rod 11 and the bracket 2. A push rod 13 is fixedly connected to the telescopic rod of the electric hydraulic cylinder 7, and the push rod 13 is in contact with the limiting rod 11. The push rod 13 squeezes the limiting rod 11, and the limiting rod 11 is squeezed to move in the direction close to the firecracker 5, and the limiting rod 11 is in contact with the firecracker 5 and limits the firecracker 5.

[0022] At first, the operator starts the two electric rollers 3. The rotation of the electric rollers 3 will drive the conveyor belt 4 to move. Then the operator places the fireworks 5 in the placement slot of the conveyor belt 4. When the conveyor belt 4 drives the fireworks 5 to move below the pressing head 14, the two electric rollers 3 stop rotating. Subsequently, the operator starts the extension of the telescopic rod of the electric hydraulic cylinder 7. The extension of the telescopic rod of the electric hydraulic cylinder 7 will drive the pressing head 14 and the push rod 13 to descend. The descent of the pressing head 14 will squeeze the labeling roll 10. The labeling roll 10 is pressurized and will drive the rotating frame 8 and the electric roller 2 91 to descend. The pressure spring 9 is stretched, and the descent of the push rod 13 will squeeze the limiting rod 11. The limiting rod 11 is squeezed and moves toward the direction close to the fireworks 5. The reset spring 12 is compressed. When the limiting rod 11 contacts the fireworks 5 and limits the fireworks 5, the limiting rod 11 no longer moves, and the pressing head 14 continues to move down. The descent will make the labeling roll 10 contact with the fireworks 5, so that the label on the labeling roll 10 will be attached to the fireworks 5, and then the telescopic rod of the electric hydraulic cylinder 7 will be reset, and the telescopic rod of the electric hydraulic cylinder 7 will be reset to drive the pressing head 14 and the push rod 13 to reset, so that the limit rod 11 and the push rod 13 will be disengaged, the reset spring 12 will be reset, and the reset spring 12 will reset and drive the limit rod 11 to reset, so that the limit rod 11 and the fireworks 5 will be disengaged, the pressing head 14 and the labeling roll 10 will be disengaged, the pressure spring 9 will be reset, and the pressure spring 9 will reset and drive the rotating frame 8 to reset, the two electric rollers 2 91 will rotate, so that the labeling roll 10 switches to the next label, and then the electric roller 1 3 will rotate to drive the conveyor belt 4 to rotate, and the conveyor belt 4 will rotate to transmit the next unlabeled firework 5 to the pressing head 14. In this way, the fireworks 5 can be limited when labeling the fireworks 5, thereby improving the labeling accuracy of the fireworks 5.

During the rotation of the rollers 16, the labels affixed to the fireworks 5 will be scraped flat.

[0024] The pressing head 14 is made of silicone.

[0025] When the telescopic rod of the electric hydraulic cylinder 7 is extended, the extension of the telescopic rod of the electric hydraulic cylinder 7 will drive the transmission frame 15 to descend, and the descent of the transmission frame 15 will drive the roller 16 to descend. The descent of the roller 16 will contact the fireworks 5 with the labels affixed, and the roller 16 will continue to descend. The roller 16 will be squeezed by the fireworks 5, and the two rollers 16 will rotate in the directions away from each other. The torsion spring 17 is twisted, and the labels affixed to the fireworks 5 will be scraped flat during the rotation of the roller 16. The resetting of the telescopic rod of the electric hydraulic cylinder 7 will drive the transmission frame 15 and the roller 16 to reset, and the roller 16 and the fireworks 5 will be separated. The resetting of the torsion spring 17 will drive the roller 16 to reset. In this way, the labels affixed to the fireworks 5 can be scraped flat, thereby improving the labeling quality.
