Description

Technical Field

[0001] This invention relates to the field of fireworks production equipment, and more particularly to a fireworks paper filling device, a fireworks production line, and fireworks. Background Technology

[0002] Fireworks are products that create colors, patterns, and sound effects when set off, primarily for their visual impact. Besides the Spring Festival to bid farewell to the old year and welcome the new, people also set off fireworks to celebrate major festivals and joyous occasions such as the Lantern Festival, Dragon Boat Festival, Mid-Autumn Festival, weddings, and housewarmings. Spray-type fireworks have a spray hole in the middle of the clay at the top of the tube. When the gunpowder is ignited, it is ejected from this hole. Because of this spray-type firework's gunpowder spray hole at the clay end, if a thin piece of paper is not used to block the hole, the gunpowder will fall out during the subsequent loading process.

[0003] Currently, the injection of thin paper into fireworks tubes is mostly done manually, one by one. This manual injection method has the following main disadvantages: First, it results in low production speed and efficiency, and high overall production costs. Second, it poses production risks; manual injection can easily lead to omissions in one or more tubes, affecting subsequent work and production safety. Third, it affects production quality; manual injection makes it difficult to control the injection effect, resulting in incomplete sealing and leakage of gunpowder during subsequent loading, thus affecting safe production.

[0078] In some embodiments, the end of the paper feeding rod 621 away from the fourth connecting plate 430 is rounded to prevent excessive force concentration on a certain point of the paper, which could damage the paper. A first spring is sleeved on the paper feeding rod 621. When the tube deviates from the paper feeding rod 621, such as when the tube is incorrectly positioned or severely deformed, the paper feeding rod 621 cannot be inserted into the tube. The first spring is compressed as the fourth connecting plate moves. A detection component is used to detect the compression state of the first spring so that the relative position of the tube and the paper feeding rod 621 can be understood through the degree of compression of the first spring, which facilitates the control of the operation of the second driving member 620.

[0079] Please see Figure 14 and Figure 15In some embodiments, a paper-pressing rod 421 is provided on the third connecting plate 420. The paper-pressing rod 421 is connected to the third connecting plate 420 and is located between the second connecting plate 410 and the third connecting plate 420. The length of the paper-pressing rod 421 is greater than the length of the paper cutter 520, and multiple paper-pressing rods 421 are evenly arranged on the side of the third connecting plate 420 near the second connecting plate 410. A third spring 422 is sleeved on the paper-pressing rod 421. The paper-pressing rod 421 and the spring move with the movement of the third connecting plate 420. When the third connecting plate 420 moves towards the paper-cutting groove 530, the paper-pressing rod 421 and the third spring 422 contact the paper in the paper-cutting groove 530 before the paper cutter 520. As the third connecting plate 420 moves, the paper-pressing rod 421 and the third spring 422 press against the paper, which can prevent the paper from moving and prevent the paper from being pressed into the paper-cutting groove 530 by the paper cutter 520 during the cutting process, thus preventing the paper from being cut. This makes the paper cut more evenly and improves the paper cutting efficiency.

The paper pieces are positioned corresponding to the odd-numbered rows of tubes. The number of paper pieces cut by the first paper cutter 521 is equal to the number of odd-numbered rows of tubes. The second driving component 620, positioned corresponding to the first paper cutting groove 540, drives the first paper-feeding rod to inject the paper pieces through the through hole 531 into the odd-numbered rows of tubes of the firework, thus completing the paper filling of one firework's odd-numbered rows of tubes. Simultaneously, another first driving component 510 drives the second paper cutter 522 to cut paper into pieces on the second paper cutting groove 550. The paper pieces cut by the second paper cutter 522 are positioned corresponding to the even-numbered rows of tubes. The second driving component 620, positioned corresponding to the second paper cutting groove 550, drives the second paper-feeding rod to inject the paper pieces through the through hole 531 into the even-numbered rows of tubes of another firework, thus completing the paper filling of the other firework's even-numbered rows of tubes. Then, the fifth driving member 820 drives the fifth connecting plate 830 to move from the first position toward the direction of the second connecting plate 410 until the fifth connecting plate 830 is in the second position, which is located between the first position and the first connecting plate 311. At the same time, the rotary bearing 810 rotates the fifth connecting plate 830 by 180° so that the fireworks that have completed the filling of the odd-numbered rows of tubes and the fireworks that have completed the filling of the even-numbered rows of tubes exchange positions. Then, the fifth driving member 820 drives the fifth connecting plate 830 to move from the second position to the first position. The first driving member 510, positioned corresponding to the fireworks whose odd-numbered rows of tubes have been filled with paper, drives the second paper cutter 522 to cut the paper into pieces on the second paper cutting groove 550, so that the paper pieces are positioned corresponding to the even-numbered rows of tubes, and the number of paper pieces is equal to the number of even-numbered rows of tubes. The second driving member 620 drives the second paper-filling rod to inject the paper pieces into the even-numbered rows of tubes of the fireworks through the through hole 531, thus completing the filling of all tubes of the fireworks. At the same time, the first driving member 510, positioned corresponding to the fireworks whose even-numbered rows of tubes have been filled with paper, drives the first paper cutter 521 to cut the paper into pieces on the first paper cutting groove 540, so that the paper pieces are positioned corresponding to the odd-numbered rows of tubes, and the number of paper pieces is equal to the number of odd-numbered rows of tubes. The second driving member 620 drives the first paper-filling rod to inject the paper pieces into the odd-numbered rows of tubes of the fireworks through the through hole 531, thus completing the filling of all tubes of another firework.The automatic filling of the firework tube by the first drive component 510, the second drive component 620, the rotary bearing 810, and the fifth drive component 820 reduces labor costs and can fill two firework tubes simultaneously, resulting in high production efficiency. By completing the filling of the entire firework tube in two stages, the area of ​​a single sheet of paper is increased, making it easier to inject the sheet into the firework tube. This also allows for filling of tubes with different apertures, improving filling efficiency. Furthermore, larger sheets of paper are less likely to fall out of the firework tube, reducing the occurrence of paper falling off during subsequent transportation and improving the quality of the firework filling.

[0099] Please see Figure 28 In some embodiments, when there are four fourth driving members 322, the filling of the firework tube and the replacement of the firework tube can be carried out simultaneously, without having to wait for the filling of the firework tube to be completed before the replacement of the firework tube, thus improving the filling efficiency of the firework tube.
