[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0024] Please refer to FIGS. 1-4. A fireworks tube gunpowder filling device includes: a base 1, a movable plate 2 is horizontally slidably arranged on the base 1, two limit sliders 6 moving in opposite directions are horizontally slidably arranged on the movable plate 2 perpendicular to the sliding direction of the movable plate 2, the two limit sliders 6 approach or move away from each other, a feed pipe 5 is arranged directly above the middle position of the base 1, a support plate 11 is fixedly connected to the movable plate 2, and an insert piece 4 passing through the feed pipe 5 is fixedly connected to the support plate 11. When the tube held by the movable plate 2 driving the limit sliders 6 is located below the feed pipe 5, filling starts, and when the movable plate 2 drives the limit sliders 6 to reset, the insert piece 4 closes the feed port of the feed pipe 5.

[0025] Specifically, in the present utility model, the tube held by the movable plate 2 driving the limit sliders 6 is horizontally moved a certain distance, and the tube closest to the feed pipe 5 is located below the feed pipe 5. As the movable plate 2 moves, the discharge port of the feed pipe 5 is opened and filling into the tube starts. Immediately afterwards, the two limit sliders 6 slide away from each other. Then, the movable plate 2 drives the limit slider 6 not holding the tube to reset, and the discharge port of the feed pipe 5 is closed by the insert piece 4. Finally, the two limit sliders 6 approach each other to clamp the tube, and the previous movement trajectory is repeated to achieve continuous filling production of the fireworks tube, greatly improving the production efficiency of fireworks.

[0026] Further, a material passing hole 41 is formed in the insert piece 4, and the cross-sectional area of the material passing hole 41 is 0.3-0.6 times the cross-sectional area of the tube feed port.

[0027] Specifically, refer to Figure 4, the cross-sectional area of the material passing hole 41 is set to be 0.3 times that of the cross-sectional area of the tube inlet, so that when the tube clamped by the movable plate 2 driving the limit slider 6 moves to the lower part of the outlet of the feed pipe 5, and then when the tube clamped by the movable plate 2 driving the limit slider 6 continues to move directly below the feed pipe 5, the insertion piece 4 also gradually opens the outlet of the feed pipe 5 until the axes of the feed pipe 5 and the tube coincide and then stops moving. Such a setting avoids the outflow of fireworks gunpowder from the tube, improves the cleanliness of the equipment table, and at the same time reduces the loss of gunpowder during the production of fireworks.

[0028] Furthermore, a guide frame 3 is fixedly connected to the base 1, and a guide groove 31 for placing the tube is opened at the top of the guide frame 3.

[0029] Specifically, referring to Figure 1 and Figure 2 , the guide frame 3 is provided to provide a feeding platform for the tube, and the guide groove 31 opened at the top of the guide frame 3 is to enable multiple tubes to move neatly in the guide groove 31.

[0030] Furthermore, a second guide rail 21 is fixedly connected to the top of the movable plate 2, two limit sliders 6 are slidably arranged on the second guide rail 21, a first slide rail 12 is fixedly connected to the top of the base 1, the movable plate 2 is slidably arranged on the first slide rail 12, a driving slider 91 is horizontally slidably arranged on the top of the movable plate 2, and two connecting rods 92 are rotatably arranged on the driving slider 91. The other ends of the two connecting rods 92 are rotatably arranged on their respective corresponding limit sliders 6.

[0031] Specifically, referring to Figure 1 and Figure 2 , the arrangement directions of the first slide rail 12 and the second guide rail 21 are perpendicular to each other. The first slide rail 12 serves the movable plate 2, and a first air cylinder 7 is fixedly installed on the base 1. The movable end of the first air cylinder 7 is fixedly connected to the movable plate 2, and the reciprocating movement of the movable plate 2 is realized through the first air cylinder 7. The second guide rail 21 serves the two limit sliders 6, and a second air cylinder 8 is fixedly connected to the top of the movable plate 2. The movable end of the second air cylinder 8 is fixedly connected to the driving slider 91, and the reciprocating movement of the driving slider 91 is realized through the second air cylinder 8, so that the connecting rods 92 rotate and the two limit sliders 6 approach or move away from each other.

[0032] Furthermore, a plurality of semi-circular grooves 61 are opened on the limit slider 6.

[0033] Specifically, referring to Figure 1 , when the two limit sliders 6 are in contact with each other, the two semi-circular grooves 61 form a circle and clamp the tube therein.

[0034] In the present utility model, referring to Figure 1, first, place multiple bobbin tubes into the guiding groove 31, and drive the driving slider 91 to move leftward through the second cylinder 8, so that the two connecting rods 92 pull the two limiting sliders 6, making the two limiting sliders 6 approach each other until a bobbin tube is clamped within the circle formed by the two semi-circular grooves 61. Immediately afterwards, the first cylinder 7 pushes the movable plate 2 to move leftward. The movable plate 2 drives the bobbin tube clamped by the limiting slider 6 to horizontally move a certain distance, and makes the bobbin tube closest to the feed pipe 5 be located below the feed pipe 5. As the movable plate 2 moves, the insertion piece 4 moves, the discharge port of the feed pipe 5 is opened and starts to fill the bobbin tube with material. Immediately afterwards, the second cylinder 8 drives the driving slider 91 to slide rightward, so that the two limiting sliders 6 slide away from each other. Finally, the first cylinder 7 drives the movable plate 2 to drive the limiting slider 6 that does not clamp the bobbin tube to reset, and the discharge port of the feed pipe 5 is closed by the insertion piece 4, completing the filling process of one bobbin tube. Repeat the previous movement trajectory to realize the continuous filling production of the fireworks bobbin tube.

[0035] Only some exemplary embodiments of the present invention have been described above by way of illustration. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
