Description

Technical Field

[0001] The utility model relates to the technical field of fireworks production, in particular to a bright bead filling device for a fireworks tube. Background Art

[0002] Filling a firework tube usually involves filling the inside of the tube with bright beads, effect medicine and other materials, mixing the materials in a predetermined proportion and then filling them to achieve different explosion effects. Due to the flammable nature of fireworks themselves, preparations need to be made to prevent smoke and dust from escaping during the filling process.

[0003] In conjunction with announcement number CN220398374U, publication date: 2024-01-26, a combined fireworks tube bright bead filling device is disclosed.

The above technology allows the bottom of the material discharge barrel to enter the upper end of the firework tube, which can prevent the bright beads from spilling out during material discharge. The threaded rod is driven to rotate by the first servo motor, and the rotation of the threaded rod can move the second connecting rod, and the second connecting rod drives the material distribution box to move, so that the material discharge barrel can load another row of firework tubes. However, during the filling process, the dust on the effect medicine and the bright beads will be dissipated along the gap between the material discharge barrel and the firework tube due to the impact force of the filling. If the gap is covered with a baffle, dust will adhere to the baffle, which is difficult to clean. Utility Model Content

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] like Figure 1-4 As shown, a device for filling bright beads into a firework tube includes a machine platform and a loading platform 5 for inserting the firework tube, including:

[0030] A material discharge box 1 driven to move in a vertical direction;

[0031] A discharge barrel 2 is fixedly arranged on the discharge box 1 and movable at the end of the fireworks tube, and a dust shielding component 3 is arranged at the lower end thereof;

[0032] The dust shielding assembly 3 includes a plurality of swing rods 31 that are circumferentially rotatable, and the swing rods 31 rotate to a predetermined angle as the unloading barrel 2 moves downward;

[0033] The dust shield 33 fixedly disposed on the swing rod 31 is used to cover the port of the fireworks tube.

[0034] Specifically, the machine is provided with a cylinder for driving the discharge box 1 to move in the vertical direction, driving the discharge box 1 and the discharge barrel 2 to move vertically downward until the port of the discharge barrel 2 is located in the port of the fireworks tube, and at the same time, the swing arm 31 moves downward with the discharge barrel 2 and abuts against the port of the fireworks tube, and is rotated to a predetermined angle due to the abutment of the port of the fireworks tube, driving the dust shield 33 to cover the port of the fireworks tube to prevent the filling material from escaping. Since the swing arm 31 is provided with a serrated rubber anti-slip pad, it will exert a force on the inner wall of the fireworks tube, so that the filling process will not cause the fireworks tube to deflect, and as the filling is completed, the discharge barrel 2 moves up and drives the swing arm 31 to rotate again, shaking off the dust adhering to the dust shield 33 during the filling process back into the fireworks tube.

[0035] In the above technology, through the design of the rocker arm 31, the rocker arm 31 moves downward with the discharge barrel 2 and abuts against the port of the fireworks tube, and is rotated to a predetermined angle due to the abutment of the port of the fireworks tube, driving the dust shield cloth 33 to cover the port of the fireworks tube to prevent the filling material from escaping, and through the rotation of the rocker arm 31, the dust adhered to the dust shield cloth 33 during the filling process is shaken back into the fireworks tube, which has a certain self-cleaning effect.

[0036] As an embodiment further provided by the present invention, the dust shielding assembly 3 also includes a slide 34 slidably arranged on the lower barrel 2, and a driving assembly 4 is arranged on the machine platform for keeping the slide 34 and the lower barrel 2 in synchronous movement, and a plurality of rubber scrapers 35 are arranged on the inner wall of the port of the slide 34 for scraping the port of the lower barrel 2.

[0037] Specifically, the rubber scraper 35 is easier to deform, and the slide 34 moves downward along with the lower barrel 2 through the driving assembly 4, so that the rubber scraper 35 moves downward to the port of the lower barrel 2. After the filling is completed, the lower barrel 2 moves upward and drives the slide 34 upward. At this time, the rubber scraper 35 is deformed and bent by the pressure at the port of the lower barrel 2, and is tightly attached to the inner wall of the lower barrel 2, while scraping the port of the lower barrel 2 to remove some filling materials that have not been completely emptied.

[0038] As another embodiment further provided by the present invention, a plurality of transmission rods 32 for rotating relative to the rocker rod 31 are rotatably provided on the slide cylinder 34 .

[0039] Specifically, the connection position between the transmission rod 32 and the slide cylinder 34 is the first end, and the other end opposite thereto is the second end. When the slide cylinder 34 moves downward, the first end of the transmission rod 32 is driven to move downward. At this time, the distance between the transmission rod 32 and the swing rod 31 is shortened, and the angle is reduced, thereby driving the swing rod 31 to radially expand along the radial direction of the cross section of the lower barrel 2 until the swing rod 31 stops when it abuts against the inner wall of the firework tube, so that the swing rod 31 can adapt to the specifications of firework tubes with different inner diameters, such as Figure 3 In the state shown, when the slide cylinder 34 moves upward, it drives the first end of the transmission rod 32 to move upward, and the swing rod 31 is pulled and rotated by the transmission rod 32, so that the dust adhered to the dust shielding cloth 33 is shaken off.

[0040] As another embodiment further provided by the present invention, an extension rod 311 is rotatably provided on the swing rod 31 , and an end portion of the transmission rod 32 is slidably provided on the extension rod 311 .

[0041] Specifically, when the slide cylinder 34 moves downward, the first end of the transmission rod 32 moves downward, thereby driving the swing rod 31 to swing, and the second end of the transmission rod 32 rotates upward, thereby driving the extension rod 311 to expand. Figure 3 In the state shown, the dust shielding cloth 33 covers a larger area, thus achieving a better dust isolation effect.

[0042] As another embodiment further provided by the present invention, the driving assembly 4 includes:

[0043] A horizontal plate 6 fixedly mounted on the slide 34 and slidably mounted on the inner wall of the machine, on which a first rack 61 is mounted;

[0044] A second rack 11 is provided on the material box 1 and is slidably provided on the inner wall of the machine platform;

[0045] The first gear 7 arranged on the inner wall of the machine is rotated to mesh with the second rack 11 for transmission;

[0046] The second gear 8 is rotatably disposed on the inner wall of the machine platform and meshes with the first rack 61 for transmission, and a third gear 81 is fixedly disposed on the second gear 8 and meshes with the first gear 7 for transmission.

[0047] Specifically, when the discharge box 1 moves downward, the second rack 11 moves downward to drive the first gear 7 to rotate forward, thereby driving the third gear 81 to rotate reversely through meshing, so that the second gear 8 rotates reversely and drives the first rack 61 to move downward, and because the number of teeth of the third gear 81 is greater than that of the second gear 8, the rotation speed of the first gear 7 is synchronously transmitted to the third gear 81 and then amplified and transmitted to the second gear 8, so that the moving directions of the first rack 61 and the second rack 11 are the same and the moving speed of the first rack 61 is greater, so that after the discharge barrel 2 moves downward into the port of the fireworks tube, the slide 34 will extend a certain distance into the fireworks tube and go deeper into the fireworks tube to prevent smoke and dust from escaping.

[0048] Working principle: The machine is provided with a cylinder for driving the material box 1 to move in the vertical direction, driving the material box 1 and the material barrel 2 to move vertically downward until the port of the material barrel 2 is located in the port of the fireworks tube. When the material box 1 moves downward, the second rack 11 moves downward to drive the first gear 7 to rotate forward, thereby driving the third gear 81 to rotate in the opposite direction through meshing, so that the second gear 8 rotates in the opposite direction and drives the first rack 61 to move downward. Because the number of teeth of the third gear 81 is greater than that of the second gear 8, the rotation speed of the first gear 7 is synchronously transmitted to the third gear 81, and then amplified and transmitted to the second gear 8, so that the first rack 61 and the first gear 81 are connected to each other. The two racks 11 move in the same direction and the first rack 61 moves at a greater speed, so that after the lower barrel 2 moves down into the end of the firework tube, the slide 34 will extend a distance into the firework tube and go deeper into the firework tube, and at the same time, the rubber scraper 35 moves downward to the end of the lower barrel 2. When the slide 34 moves downward, the first end of the transmission rod 32 is driven to move downward. At this time, the distance between the transmission rod 32 and the swing rod 31 is shortened, and the angle is reduced, thereby driving the swing rod 31 to radially expand along the radial direction of the cross section of the lower barrel 2 until the swing rod 31 stops against the inner wall of the firework tube, so that the swing rod 31 can adapt to the specifications of firework tubes with different inner diameters, such as Figure 3The second end of the transmission rod 32 rotates upward, thereby driving the extension rod 311 to unfold, so that the coverage area of ​​the dust shield 33 is larger, which has a better effect of isolating dust; as the filling is completed, the lower barrel 2 moves up and drives the slide cylinder 34 to move up. At this time, the rubber scraper 35 is deformed and bent by the pressure at the port of the lower barrel 2, and is tightly attached to the inner wall of the lower barrel 2. At the same time, the port of the lower barrel 2 is scraped to remove some filling materials that have not been completely emptied. When the slide cylinder 34 moves up, it drives the first end of the transmission rod 32 to move upward, and the swing rod 31 is pulled and rotated by the transmission rod 32, so that the dust adhered to the dust shield 33 is shaken off, which has a certain self-cleaning effect, and drives the extension rod 311 to retract. Figure 2 State shown, saves space.

[0049] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. 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.
