Description

Technical Field

[0001] This utility model relates to the field of fireworks and firecrackers production, and in particular to an automatic quantitative feeding device for bright beads. Background Technology

[0002] Firework sparklers are gunpowder particles composed of metal salts, oxidizers, reducing agents, and binders. These components collectively determine the sparkler's color and combustion characteristics. The choice of metal salts determines the sparkler's color, while the oxidizers and reducing agents provide the oxygen and combustibles needed for combustion, and the binder shapes and holds the sparkler together. When the firework is ignited, the gunpowder at the base explodes first, launching the effect component into the air. Upon reaching a certain height, the fuse inside the effect component detonates the gunpowder, blasting the sparkler in various directions and causing it to burn—this is the firework we see. The sparkler effects can be adjusted according to different needs, including brightness, color, and duration. By changing the proportions and types of components in the firework's powder, sparkler effects of different colors and brightness can be created.

[0003] Currently, the device for filling sparkling beads into fireworks paper tubes typically places the sparkling beads in a sliding frame. The frame swings to fill a metering block at the bottom with sparkling beads, and then the sparkling beads in the metering block are introduced into the fireworks paper tube, completing one sparkling bead metering operation. However, the metering block in the existing device is usually in a stopped state, while the frame swings in one direction. This causes the sparkling beads to roll in the opposite direction to the frame's swing direction, resulting in a large dead zone in the filling process. This leads to missing sparkling beads, inconsistent quality, and affects the quality of the finished fireworks.

[0004] Therefore, we are now developing an automatic quantitative feeding device for bright beads that can improve the feeding accuracy and eliminate the problem of missing beads, thereby improving the feeding quality and precision of bright beads. Utility Model Content

[0005] In order to overcome the shortcomings of the above-mentioned background technology, the present invention provides an automatic quantitative feeding device for bright beads that can improve the falling accuracy of bright beads and prevent the problem of missing beads, thereby improving the quality and accuracy of bright bead feeding.

[0006] The technical solution of this utility model is as follows: An automatic quantitative feeding device for bright beads includes a mounting box, a swing frame, a first electric push rod, a rotating disk, a quantitative block, and a driver. The top of the mounting box has a feeding port, and the swing frame is slidably connected inside the mounting box. The first electric push rod is connected to both the left and right sides of the mounting box. The telescopic end of the first electric push rod passes through the mounting box and connects to the swing frame. The rotating disk is connected to the bottom of the mounting box. The top of the rotating disk contacts the bottom of the swing frame. A quantitative block is connected to the rotating disk. The driver is connected to the bottom of the mounting box, and the output shaft end of the driver contacts the rotating disk.

[0007] Furthermore, it is particularly preferred that the filling port has a raised structure.

[0008] In addition, it is particularly preferred that the frame also includes guide posts, with multiple guide posts connected to both the left and right sides of the swing frame, and the guide posts passing through the mounting box.

[0009] In addition, it is particularly preferred that the device also includes a mounting plate, a second electric actuator, and a baffle. The mounting plate is connected to both the left and right sides of the lower part of the mounting box. The second electric actuator is connected to the mounting plate, and the baffle is connected to the telescopic end of the second electric actuator. The baffles are in contact with each other.

[0010] Furthermore, it is particularly preferred that the device also includes a cylinder and a placement platform, with the cylinder connected to the rear side of the mounting box and the placement platform connected to the telescopic end of the cylinder.

[0011] Furthermore, it is particularly preferred that the device also includes positioning blocks, with multiple positioning blocks connected to the placement platform.

[0012] The beneficial effects of this utility model are as follows: 1. This utility model controls the left and right reciprocating motion of the swing frame through the first electric push rod. The left and right reciprocating motion of the swing frame controls the rolling of the internal bright beads. At the same time, the driver controls the rotation of the rotating disk. The rotation of the rotating disk drives the quantitative block to rotate. The rotation of the quantitative block, in conjunction with the left and right swing of the swing frame, enables the bright beads to fall accurately into the holes on the quantitative block, without any missing beads, thus improving the quality and accuracy of the bright beads feeding.

[0013] 2. This utility model uses a cylinder to control the placement platform to move downwards, making it easier to place the firework paper tube on the platform. After placement, the cylinder's extension end controls the placement platform to move upwards, so that the top of the firework paper tube contacts the bottom of the baffle, making it easier to receive the bright beads in the metering block, thus improving the accuracy and convenience of bright bead feeding.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0021] An automatic quantitative feeding device for bright beads, such as Figures 1-5 As shown, the assembly includes a mounting box 1, a swing frame 3, a first electric actuator 5, a rotating disk 6, a metering block 7, and a driver 8. The mounting box 1 has a feeding port 2 at its top. The swing frame 3 is slidably connected inside the mounting box 1. First electric actuators 5 are connected to both the left and right sides of the mounting box 1. The telescopic ends of the first electric actuators 5 pass through the mounting box 1 and connect to the swing frame 3. The rotating disk 6 is connected to the bottom of the mounting box 1, with its top contacting the bottom of the swing frame 3. The metering block 7 is connected to the rotating disk 6. The driver 8 is connected to the bottom of the mounting box 1, and the output shaft of the driver 8 connects to the rotating disk 6. The ball is introduced through the feeding port 2 and falls into the enclosure of the swing frame 3. The first electric push rod 5 controls the swing frame 3 to move back and forth. The swing frame 3 controls the internal ball to roll. At the same time, the driver 8 controls the rotating disk 6 to rotate. The rotating disk 6 drives the metering block 7 to rotate. The rotation of the metering block 7, in conjunction with the left and right swing of the swing frame 3, allows the ball to fall accurately into the hole on the metering block 7 until the hole is filled. After the hole is filled, the first electric push rod 5 controls the swing frame 3 to deflect to either side of the left or right, and the bottom no longer contacts the rotating disk 6.

[0022] The feeding port has two raised structures to facilitate connection to the bright bead inlet device;

[0023] It also includes guide posts 4. Multiple guide posts 4 are connected to both the left and right sides of the swing frame 3. The guide posts 4 pass through the mounting box 1. When the swing frame 3 swings back and forth, the guide posts 4 move together. The guide posts 4 can ensure the stability of the swing frame 3 when it swings.

[0024] It also includes a mounting plate 9, a second electric push rod 10, and a baffle 11. The mounting plate 9 is connected to the lower left and right sides of the mounting box 1. The second electric push rod 10 is connected to the mounting plate 9. The baffle 11 is connected to the telescopic end of the second electric push rod 10. The baffles 11 are in contact with each other. After the bright beads fill the quantitative block 7, the telescopic end of the second electric push rod controls the baffles 11 to move away from each other, so that the bottom of the quantitative block 7 is exposed. The bright beads in the quantitative block 7 fall into the filling firework paper tube. After a batch of bright beads is quantitatively discharged, the second electric push rod 10 controls the baffle 11 to reset and cover the bottom of the quantitative block 7 again.

[0025] It also includes a cylinder 12 and a placement platform 13. The cylinder 12 is connected to the rear side of the mounting box 1. The placement platform 13 is connected to the telescopic end of the cylinder 12. The cylinder 12 controls the placement platform 13 to move downward, so that the firework paper tube can be placed on the placement platform 13. After placement, the telescopic end of the cylinder 12 controls the placement platform 13 to move upward, so that the top of the firework paper tube contacts the bottom of the baffle 11, so as to receive the bright beads in the metering block 7.

[0026] It also includes positioning blocks 14. Multiple positioning blocks 14 are connected to the placement platform 13. The positioning blocks 14 facilitate the placement and positioning of the firework paper tubes, improving the accuracy and convenience of feeding the bright beads.

[0027] In use, this invention introduces bright beads through the feeding port 2. The beads fall into the enclosure of the swing frame 3. The first electric push rod 5 controls the swing frame 3 to reciprocate left and right. The reciprocating motion of the swing frame 3 controls the rolling of the bright beads inside. At the same time, the driver 8 controls the rotating disk 6 to rotate. The rotation of the rotating disk 6 drives the metering block 7 to rotate. The rotation of the metering block 7, in conjunction with the left and right swing of the swing frame 3, ensures that the bright beads can accurately fall into the holes on the metering block 7 until the holes are filled. After the holes are filled, the first electric push rod 5 controls the swing frame 3 to deflect to either side, so that the bottom no longer contacts the rotating disk 6. Then, the air... Cylinder 12 controls the placement platform 13 to move downwards, making it easier to place the firework paper tube on the placement platform 13. After placement, the extension end of cylinder 12 controls the placement platform 13 to move upwards, so that the top of the firework paper tube contacts the bottom of the baffle 11, making it easier to receive the bright beads in the metering block 7. After the bright beads fill the metering block 7, the extension end of the second electric push rod controls the baffle 11 to move away from each other, so that the bottom of the metering block 7 is exposed, and the bright beads in the metering block 7 fall into the filled firework paper tube. After a batch of bright beads is metered out, the second electric push rod 10 controls the baffle 11 to reset, and the bottom of the metering block 7 is covered again.

[0028] It should be understood that this embodiment is for illustrative purposes only and is not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
