Detailed implementation method:
[0022] The following are specific embodiments of this utility model, and the technical solution of this application will be further described in a complete and clear manner with reference to the accompanying drawings. Figure 1 In the overall structural diagram of the Zhongben Fireworks Bright Bead Granulator, the labels 1 (bright bead raw material supply device), 2 (bright bead raw material conveying device), 3 (bright bead granulation device), 4 (bright bead conveying device), 5 (bright bead screening device), and 6 (powder recovery device) only indicate the location of each device, not the location of any specific component within each device. Figure 2 , Figure 3 The labels in the text may have overlapping locations.
[0023] Reference Figure 1-4 A fireworks sparkling bead granulator includes, in sequence, a sparkling bead raw material supply device 1, a sparkling bead raw material conveying device 2, a sparkling bead granulation device 3, a sparkling bead conveying device 4, a sparkling bead screening device 5, and a powder recovery device 6, all mounted on a frame. The feed pipe 10 of the sparkling bead raw material conveying device 2 extends into the sparkling bead granulation tank 12 of the sparkling bead granulation device 3.
[0024] The powder recovery device 6 includes a first hopper 7, a first conveyor belt 8, and a drive mechanism for driving the first conveyor belt 8, all located below the bright bead screening device 5. The drive mechanism includes a first motor 9, a drive roller, and a driven roller (not shown in the figure) fixed on the frame. The first conveyor belt 8 is located at the bottom of the first hopper 7 and is mounted on the frame from bottom to top via rollers. The first motor 9, drive roller, and driven roller are located on the frame on the side of the second hopper 11. The bright bead raw material conveying device 4 includes a feed pipe 10 and a second hopper 11 mounted on the feed pipe 10.
[0025] After the bright beads are made, they need to be screened by the bright bead screening device 5 according to particle size. Powder on the surface of the bright bead particles will fall off during the screening process. The first hopper 7 is located at the bottom of the bright bead screening device 5 to collect all the dust. This dust can be recycled and used as raw material for bright beads to be granulated again.
[0026] Driven by the first motor 9, the first conveyor belt 8 transports the powder collected in the first hopper 7 to the second hopper 11 opened on the feed pipe 10 of the bright pearl raw material conveying device 4. The first motor 9 is a servo motor, and the stable operation and efficient transmission of the first conveyor belt 8 are ensured by adjusting the center distance between the driving roller and the driven roller.
[0027] The bright bead raw material supply device 1 includes an automatic lifting and unloading mechanism and a quantitative unloading mechanism.
[0028] The automatic lifting and unloading mechanism includes a drive wheel 14 and a driven wheel 15 mounted at the upper and lower ends of the first support 13, a synchronous belt 16 connecting the drive wheel 14 and the driven wheel 15, a third hopper 20, a pair of guide grooves 17 on both sides of the synchronous belt 16, and a second motor 18 for driving the drive wheel 15 to rotate. The synchronous belt 16 has toothed surfaces on its inner side, meshing with the drive wheel 14 and the driven wheel 15; the drive wheel 14 and the driven wheel 15 are mounted on bearing seats via bearings; the bearing seats are fixedly connected to the first support 13 (neither the bearings nor the bearing seats are shown in the figure). The bottom of the third hopper 20 is fixedly connected to the synchronous belt 16 by bolts. Rollers (not shown in the figure) are provided on both sides of the third hopper 20. The rollers roll within the guide grooves 17 to ensure smooth movement of the third hopper 20 without tilting. For ease of equipment installation and overall design, a cornering device 21 connects the drive wheel 14 and the second motor 18.
[0029] The quantitative feeding mechanism includes a fourth hopper 23 fixed on the second support 22 and a conveying assembly located at the bottom of the fourth hopper 23. The fourth hopper 23 has only four walls, with the upper and lower parts being open. The conveying assembly includes a drive shaft 27, a driven shaft 28, and a second conveyor belt 29 fixedly connected to the second support 22. The drive shaft 27 is connected to the driven shaft 28 via the second conveyor belt 29. The drive shaft 27 is connected to a third motor (not shown in the figure). The second conveyor belt 29 closes the bottom of the fourth hopper 23, forming the bottom wall of the fourth hopper 23. A weighing sensor 24 is installed at the bottom of the second conveyor belt 29. To accurately measure the mass of the bright bead raw material mixture, three weighing sensors 24 are used, and the connecting lines of the three weighing sensors 24 form a triangle. The discharge end of the fourth hopper 23 is equipped with a valve 25; a drive cylinder 26 is installed on the outer wall of the discharge end of the fourth hopper 23 to control the opening and closing of the valve 25; if the drive cylinder 26 does not have a built-in magnetic switch, the side plate of the drive cylinder 26 is fixed with a fixing ring to fix the magnetic switch (not shown in the figure) to receive the signal sent by the weighing sensor 24.
[0030] At least one support plate (not shown in the figure) is fixedly connected to the second bracket 22 on the outer wall of the fourth hopper 23. The support plate is provided to make the fourth hopper 23 more stable, so as not to tilt during production and prevent safety accidents. A dust cover is provided on the upper part of the fourth hopper 23 to prevent dust from overflowing when receiving bright bead raw materials.
[0031] The loosening component of the quantitative feeding mechanism includes a fourth motor 31 fixed on the outer wall of the fourth hopper 23 and a loosening rotating shaft (not shown in the figure); the loosening rotating shaft passes through the outer wall of the fourth hopper 23, one end of the loosening rotating shaft is connected to the output shaft of the fourth motor 31, and the other end is fixed inside the fourth hopper 23 through a bearing seat (not shown in the figure), and the bearing seat is installed on the inner wall of the fourth hopper 23.
[0032] The discharge end of the fourth hopper 23 is equipped with a fifth hopper 32, and the discharge end of the fifth hopper 32 is connected to the discharge pipe 33.
[0033] During the production of bright beads granulation, the mixture of bright bead raw materials is transported from the discharge pipe 33 of the bright bead raw material supply device 1 to the feed pipe 10 in the bright bead raw material conveying device 2, and then transported to the bright bead granulation tank 12 in the bright bead granulation device 3 for bright bead granulation.
[0034] The mixture of bright bead granules is poured into the third hopper 20 of the automatic lifting and unloading mechanism of the bright bead raw material supply device 1. The second motor 18 is a servo motor. The output shaft of the second motor 18 is connected to one end of the transmission shaft 19, and the other end of the transmission shaft 19 is connected to the input shaft of the angler 20. The output shaft of the angler 20 is connected to the bearing of the drive wheel 14. When the second motor 18 starts, it transmits power to the bearing of the drive wheel 14 through the transmission shaft 19 and the angler 20, causing the drive wheel 14 to rotate. Correspondingly, the driven wheel 15, which is connected to the drive wheel 14 through the synchronous belt 16, rotates. The third hopper 20, which is fixed on the synchronous belt 16, moves upward within the position defined by a pair of guide grooves 17, and is lifted to the predetermined top position. The synchronous belt 16 continues to rotate. As the third hopper 20 continues to move downward with the synchronous belt 16, it flips over, pouring the mixture of bright bead granules into the fourth hopper 23. The mixture of bright bead granules falls onto the second conveyor belt 29 at the bottom of the fourth hopper 23. The third motor starts, and the drive shaft 27 connected to the output shaft of the third motor rotates. The driven shaft 28 and the second conveyor belt 29 rotate accordingly. The bright bead granule raw material mixture moves towards the discharge end of the fourth hopper 23 along the rotation direction of the second conveyor belt 29. The weighing sensor 24 senses the mass of the bright bead granule raw material mixture in the fourth hopper 23 and transmits the signal to the magnetic switch on the drive cylinder 26 according to the preset mass data. The drive cylinder 26 starts, and the piston rod of the drive cylinder 26 is connected to the valve 25, pushing the valve 25 away from the discharge end of the fourth hopper 23, opening the discharge end. The bright bead granule raw material mixture enters the fifth hopper 32, and is then transported to the feed pipe 10 through the discharge pipe 33 connected to the fifth hopper 32, and then transported to the bright bead granulation tank 12 to complete granulation.
[0035] During the conveying process of the bright bead granule raw material mixture, after the bright bead granule raw material mixture in the fourth hopper 23 is discharged, the piston rod of the drive cylinder 26 retracts, and the valve 25 closes the discharge end of the fourth hopper 23, waiting for the next working process.
[0036] After the bright beads are granulated, the bright bead conveying device 4 conveys the bright beads to the bright bead screening device 5 for screening according to the size of the bright bead particles. During the screening process, the powder on the surface of the bright bead particles falls into the first hopper 7 at the bottom of the bright bead screening device 5. The first motor 9 is started under the control of the main controller. The first conveyor belt 8, driven by the first motor 9, conveys the powder collected in the first hopper 7 to the second hopper 11 and then into the feed pipe 10. The powder is then conveyed to the bright bead granulation tank 12 through the feed pipe 10 for bright bead granulation.
