[0002] In the production of fireworks, yellow mud is needed to seal the bottom, and the quality of the yellow mud sealing has the most direct impact on the quality of the fireworks. The existing devices all manually place the molded firework shells on a work platform with a vertical limiting rod. Since the molded firework shells are placed manually, some molded firework shells will not be fully in contact with the work platform, and the height of the yellow mud in the molded firework shells after being pressed and formed will be high and low, which will make the yellow mud pressing effect in the molded firework shells not good enough. Moreover, after the pressing is completed, the yellow mud will be in close contact with the limiting rod, making it difficult to easily remove the molded firework shells after the yellow mud is pressed. Utility Model Content

DETAILED DESCRIPTION
[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] Embodiment 1: A fireworks suppression device, such as Figure 1-Figure 6 As shown, it includes a base 1, a fixed block 2, a hydraulic rod 3, a pressure frame 4, an extrusion rod 41, a contact plate 5 and a compression spring 6. A fixed block 2 is welded on both sides of the base 1. Each fixed block 2 is connected to a hydraulic rod 3 by bolts. The upper ends of the telescopic rods of the two hydraulic rods 3 are commonly fixedly connected to the pressure frame 4. A plurality of extrusion rods 41 are welded to the bottom of the pressure frame 4. The plurality of extrusion rods 41 are used to extrude yellow mud. A contact plate 5 is slidably connected to the plurality of extrusion rods 41. Two compression springs 6 are connected between the contact plate 5 and the pressure frame 4.
[0019] It also includes a sliding frame 7, a limiting rod 8, a motor bracket 9, a driving motor 10, a rotating screw 11 and a threaded sleeve 12. One end of the base 1 is slidably connected to the sliding frame 7, and a plurality of limiting rods 8 are rotatably connected to the sliding frame 7. A motor bracket 9 is welded to one side of the base 1. The driving motor 10 is connected to the motor bracket 9 by bolts. The output shaft of the driving motor 10 is fixedly connected to the rotating screw 11. A threaded sleeve 12 is welded to the sliding frame 7. The threaded sleeve 12 is connected to the rotating screw 11 by threads. A molded firework shell 13 is placed on the sliding frame 7. The molded firework shell 13 has a plurality of through holes. The plurality of through holes of the molded firework shell 13 are respectively in contact with a plurality of limiting rods 8.
[0020] At first, the staff puts the molded firework shell 13 on the sliding frame 7, and the through hole of the molded firework shell 13 is sleeved on the limiting rod 8. Then the staff puts yellow mud into the through hole of the molded firework shell 13, and the yellow mud will contact the limiting rod 8. Finally, the staff starts the driving motor 10, and the driving motor 10 will drive the rotating screw rod 11 to rotate. The rotation of the rotating screw rod 11 will squeeze the threaded sleeve 12 through the thread on the rotating screw rod 11 to make the threaded sleeve 12 move. The movement of the threaded sleeve 12 will drive the sliding frame 7, the limiting rod 8, the molded firework shell 13 and the yellow mud to move. After the sliding frame 7 moves to the other end of the base 1, the staff turns off the driving motor 10 and starts the hydraulic rod 3. The downward movement of the hydraulic rod 3 will drive the pressing frame 4, the extrusion rod 41, the contact plate 5 and the compression spring 6 to move downward. The contact plate 5 will first contact the molded firework shell 13, and the pressing frame 4 and the extrusion rod 41 continue to move downward. The pressing frame 4 continues to move downward, so that the compression spring 6 is compressed. The compression of the compression spring 6 causes the contact plate 5 to tightly fit the molded firework shell 13 with the sliding frame 7. The extrusion rod 41 moves downward and contacts the through hole of the molded firework shell 13. The extrusion rod 41 continues to move downward and contacts the yellow mud in the through hole of the molded firework shell 13. Then the extrusion rod 41 squeezes the yellow mud onto the limiting rod 8, so that the yellow mud in the through hole of the molded firework shell 13 is pressed and formed. The pressed yellow mud is fixed in the through hole of the molded firework shell 13. The contact plate 5 makes the molded firework shell 13 fit tightly with the sliding frame 7, so that the height of the pressed yellow mud in the through hole of the molded firework shell 13 is the same, thereby making the molded firework shell 13 3 has a better pressing effect. After the yellow mud in the molded fireworks shell 13 is pressed and formed, the hydraulic rod 3 moves upward to drive the pressing frame 4, the extrusion rod 41, the contact plate 5 and the compression spring 6 to reset. The staff starts the drive motor 10, and the drive motor 10 drives the rotating screw rod 11 to reverse. The rotating screw rod 11 reverses and drives the sliding frame 7, the limiting rod 8 and the molded fireworks shell 13 pressed with yellow mud to reset through the threaded sleeve 12. The staff takes the molded fireworks shell 13 pressed with yellow mud out of the sliding frame 7 and the limiting rod 8.
[0021] Embodiment 2: Based on embodiment 1, Figure 2-Figure 3 As shown, it also includes a rotating gear 14 and a rack 15. A rotating gear 14 is welded to the bottom of each limiting rod 8. The rotating gears 14 in each column are grouped together. There are four groups of rotating gears 14. Two racks 15 are welded to the bottom of the base 1. Each rack 15 will mesh with two adjacent groups of rotating gears 14.
[0022] The movement of the sliding frame 7 will drive the limiting rod 8, the molded fireworks shell 13 and the rotating gear 14 to move. Since the rack 15 is meshed with the rotating gear 14, the movement of the rotating gear 14 will cause the rotating gear 14 to rotate. The rotation of the rotating gear 14 will drive the limiting rod 8 to rotate. After the yellow mud in the through hole of the molded fireworks shell 13 is pressed and formed, the pressed yellow mud will be in close contact with the limiting rod 8, making it difficult for the staff to easily remove the molded fireworks shell 13 with pressed yellow mud from the limiting rod 8. The rotation of the limiting rod 8 will break away from the contact with the yellow mud in the through hole of the molded fireworks shell 13, so that the molded fireworks shell 13 with pressed yellow mud can be easily removed from the limiting rod 8. The sliding frame 7 stops moving, causing the moving gear and the limiting rod 8 to stop rotating.
[0023] Example 3
[0024] On the basis of Example 2, Figure 4-Figure 5 As shown, a pulling frame is also included, and the sliding frame 7 is slidably connected to the pulling frame.
[0025] At first, when the staff places the molded fireworks shell 13 on the sliding rack 7, the molded fireworks shell 13 will contact the pulling rack. After the yellow mud in the through hole of the molded fireworks shell 13 is pressed into shape, the staff lifts the pulling rack so that the molded fireworks shell 13 pressed with yellow mud can be quickly separated from the sliding rack 7, making it convenient for the staff to quickly take out the molded fireworks shell 13 pressed with yellow mud.
[0026] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
