[0002] Sealing is a key link in the production of fireworks. Its main function is to seal the launching port of the firework tube so as to isolate the propellant and the burning powder in the firework tube from the outside world. The traditional sealing of firework tubes is done manually, and the sealing efficiency is low. When the existing sealing device seals the firework tube, it cannot restrict the firework tube well. When the sealing plate is pushed into the firework tube, the firework tube is prone to deviation, resulting in the firework tube sealing is not accurate enough, and the sealing plate needs to be manually placed at the sealing position of the firework tube, which results in low sealing efficiency of the firework tube.

[0009] Compared with the prior art, the utility model has the following advantages: 1. The rotation of the turntable will drive the firework tube to rotate together. During the rotation of the turntable, the limit plate will squeeze one of the clamping rods on the turntable, so that one of the clamping rods will move toward the center of the turntable, one of the pressure springs will be compressed, and one of the clamping rods will clamp the firework tube, making the firework tube more stably fixed, so that the sealing plate can be pushed into the firework tube more accurately, thereby improving the sealing efficiency.

Since the bottom of one of the perforations is supported by the bottom plate 4, the firework tube will not fall out of the perforation of the turntable 3. Then the operator starts the motor 5. The counterclockwise rotation of the output shaft of the motor 5 will drive the turntable 3 to rotate counterclockwise. The rotation of the turntable 3 will drive the firework tube to rotate together. During the rotation of the turntable 3, the limit plate 8 will squeeze one of the clamping rods 6 on the turntable 3, so that one of the clamping rods 6 will move toward the center of the turntable 3. One of the pressure springs 7 is compressed, and one of the clamping rods 6 will clamp the firework tube. When the turntable 3 drives the firework tube to move to the bottom of the hydraulic cylinder 91, the motor 5 stops rotating. Then the operator The operator places the sealing plate at the sealing position of the firework tube, and then the operator starts the hydraulic cylinder 91, the telescopic rod of the hydraulic cylinder 91 will extend, and the extension of the telescopic rod of the hydraulic cylinder 91 will push the sealing plate into the firework tube, thus completing the sealing process of the firework tube, and then the motor 5 rotates again, and the output shaft of the motor 5 drives the turntable 3 to continue to rotate, so that one of the clamping rods 6 and the limit plate 8 are disengaged, and one of the pressure springs 7 drives one of the clamping rods 6 to reset, and one of the clamping rods 6 no longer clamps the firework tube, and the firework tube will fall out of the perforation of the turntable 3, so that the firework tube can be clamped when sealing the firework tube, so that the firework tube is fixed more stably, so that the sealing plate can be pushed into the firework tube more accurately, thereby improving the sealing efficiency.

[0022] The bottom plate 4 is used to support the firework tube placed in the perforation of the turntable 3 to prevent the firework tube from falling.

[0023] Two of the clamping rods 6 are in contact with the limiting plate 8, and the limiting plate 8 squeezes two of the clamping rods 6, so that the two clamping rods 6 clamp the firework tube.

The next sealing plate in the discharge barrel 10 will fall onto the feeding plate 11. When the push rod 12 and the sealing plate are separated, the sealing plate will stagnate under the hydraulic cylinder 91. In this way, when the telescopic rod of the hydraulic cylinder 91 is extended, the sealing plate will be pushed into the firework tube, and so on. In this way, the sealing plate can be automatically added to the top of the firework tube seal, which is convenient for continuous sealing of the firework tube and further improves the sealing efficiency of the firework tube.
