For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0024] See also Figure 1-4 The utility model provides an embodiment: a mixing mechanism for fireworks explosive drug in a tube, comprising a primary conveyor belt 1 and a secondary conveyor belt 2, wherein the primary conveyor belt 1 and the secondary conveyor belt 2 are responsible for feeding and discharging the fireworks tube respectively;

[0025] A fixed seat 3 is provided between the primary conveyor belt 1 and the secondary conveyor belt 2, and a rotating motor 4 is fixedly installed on the upper surface of the fixed seat 3. A primary runner 5 is fixedly installed on the output shaft of the rotating motor 4. A secondary runner 6 is provided on one side of the primary runner 5. The primary runner 5 and the secondary runner 6 are connected by belt transmission. The back of the secondary runner 6 is fixedly connected to the tertiary runner 7 through a connecting shaft. Both ends of the connecting shaft between the secondary runner 6 and the tertiary runner 7 are fixedly sleeved with eccentric wheels 9. A fourth runner 8 is provided on one side of the tertiary runner 7. The third runner 7 and the fourth runner 8 are rotationally connected by a belt. A secondary connecting shaft is fixedly installed on one side of the fourth runner 8. Both ends of the secondary connecting shaft are fixedly sleeved with eccentric wheels 9. A vibration platform 10 is fixedly sleeved between the outsides of the four eccentric wheels 9, and a third conveyor belt 11 is fixedly installed on the vibration platform 10.

[0026] According to the above structure, the rotary motor 4 can be rotated. When the rotary motor 4 rotates, it drives the primary runner 5 to rotate through the output shaft. When the primary runner 5 rotates, it drives the secondary runner 6 to rotate through the belt. When the secondary runner 6 rotates, it drives the tertiary runner 7 at the other end of the shaft body to rotate through the connecting shaft. When the tertiary runner 7 rotates, it drives the quaternary runner 8 on one side to rotate through the belt. In this way, a single rotary motor 4 can simultaneously drive multiple runners to rotate.

[0027] When multiple wheels rotate synchronously, the four eccentric wheels 9 connected to their shafts can rotate synchronously, so that the rotation of the eccentric wheels 9 can drive the vibration platform 10 thereon to move up and down;

[0028] When the rotary motor 4 rotates at high speed, the vibration platform 10 can perform high-frequency vibration up and down through the action of the eccentric wheel 9, so that the high-frequency vibration of the vibration platform 10 can drive the fireworks tube on it to vibrate at high speed, thereby effectively performing high-frequency vibration mixing on the medicine in the fireworks tube through the effect of high-speed vibration, achieving a comprehensive mixing effect of multiple materials and improving the efficiency and uniformity of medicine mixing;

[0029] This can effectively improve the production quality of fireworks and enhance the firing effect. At the same time, machines can replace manual operations. While meeting the above technical effects, it can effectively reduce human resource cost investment, reduce the production cost of fireworks, and enhance the economic benefits of the enterprise, with good use effect.

[0030] In this embodiment, a plurality of clamping cylinders 12 are installed on both sides of the interior of the three-stage conveyor belt 11. The clamping cylinders 12 are arranged opposite to each other in pairs. The output ends of the clamping cylinders 12 are telescopically connected to gas rods, and a movable plate 13 is fixedly installed on the top of the gas rods. The gas rods can be driven to extend and retract by the clamping cylinders 12. When the gas rods are extended and retracted, the movable plate 13 can move forward and backward.

[0031] Furthermore, clamping plates 14 are fixedly installed on both sides of the upper side of the movable plate 13 through a rod body. The clamping plates 14 are provided with two movable grooves, and the two movable grooves are slidably connected with clamping claws 15. The two clamping claws 15 are arranged opposite to each other. When the clamping claws 15 need to be fixed, they can be tightened and fixed by bolts to fix them in the movable grooves of the clamping plates 14.

[0032] This structural design, through the provided clamping cylinder 12, can drive the pneumatic rod to extend and retract. When the pneumatic rods on both sides are retracted, the clamping claws 15 on both sides can move to one side of the three-stage conveyor belt 11. At this time, the distance between the clamping claws 15 on both sides is reduced. The clamping claws 15 provided on both sides can clamp and fix the bundled firework tubes externally, thereby effectively improving the structural stability of the vibration mixer and having a better use effect.

[0033] Moreover, the clamping claws 15 of the present invention can slide left and right, thereby changing the distance between the two clamping claws 15 on the clamping plate 14, thereby completing the external clamping and fixing work of firework paper tubes of different sizes. In actual use, it can be applied to firework paper tubes of different specifications and models for mixing and processing the internal medicine, effectively improving the size application range and reducing the limitation of use.

[0034] In this embodiment, in order to seal and cap the upper end of the firework tube, columns 16 are fixedly installed at the four corners of the outer surface of the three-stage conveyor belt 11, and a fixed crossbar 17 is fixedly installed between the tops of two adjacent columns 16 on the same side;

[0035] Furthermore, a pressing cylinder 18 is fixedly installed at the center position of the outer surface of the fixed crossbar 17, and a movable crossbar 19 is fixedly installed at the fixed bottom end of the output rod of the pressing cylinder 18. Both sides of the movable crossbar 19 are sleeved on the outside of the column 16 and are slidably connected to the column 16. A pressing cover plate 20 is fixedly installed between the two movable crossbars 19;

[0036] According to the above structure, the set pressing cylinder 18 can drive the movable cross bar 19 at the bottom end to descend through its output rod. When the two movable cross bars 19 descend, the pressing cover plate 20 between the two descends synchronously. In this way, the upper end of the firework paper tube can be pressed and sealed by the descending pressing cover plate 20 to avoid drug overflow during vibration mixing, thereby improving the mixing processing effect.

[0037] Working principle: When the utility model is in use, the bundled fireworks paper tubes can be transported through the primary conveyor belt 1, so that the fireworks paper tubes can be transported to the tertiary conveyor belt 11. In actual use, the tertiary conveyor belt 11 is provided with a sensor. When the sensor senses the material, the tertiary conveyor belt 11 stops working.

[0038] Afterwards, the clamping cylinder 12 and the pressing cylinder 18 can work synchronously;

[0039] The clamping cylinder 12 is provided to drive the pneumatic rod to extend and retract. When the pneumatic rods on both sides are retracted, the clamping claws 15 on both sides can move to one side of the three-stage conveyor belt 11. At this time, the distance between the clamping claws 15 on both sides is reduced. The clamping claws 15 provided on both sides can clamp and fix the bundled firework tubes on both sides, thereby effectively improving the structural stability of the subsequent vibration mixing and having a better use effect.

[0040] When the pressing cylinder 18 is working, the movable cross bar 19 at the bottom can be driven to descend by its output rod. When the two movable cross bars 19 descend, the pressing cover plate 20 between them will descend synchronously. In this way, the upper end of the firework paper tube can be pressed and sealed by the descending pressing cover plate 20 to prevent the drug from overflowing during vibration mixing and improve the mixing processing effect.

[0041] After the clamping claws 15 clamp the fireworks paper tube and the pressing cover plate 20 presses and seals the upper end of the paper tube, the rotating motor 4 can now work. When the rotating motor 4 rotates, it drives the first-stage runner 5 to rotate through the output shaft. When the first-stage runner 5 rotates, it drives the second-stage runner 6 to rotate through a belt. When the second-stage runner 6 rotates, it drives the third-stage runner 7 at the other end of the shaft body to rotate through the connecting shaft. When the third-stage runner 7 rotates, it drives the fourth-stage runner 8 on one side to rotate through a belt. In this way, a single rotating motor 4 can simultaneously drive multiple runners to rotate.

[0042] When multiple wheels rotate synchronously, the four eccentric wheels 9 connected to their shafts can rotate synchronously, so that the rotation of the eccentric wheels 9 can drive the vibration platform 10 thereon to move up and down;

[0043] When the rotating motor 4 rotates at high speed, the vibration platform 10 can perform high-frequency vibration up and down through the action of the eccentric wheel 9, so that the high-frequency vibration of the vibration platform 10 can drive the firework paper tube on it to vibrate at high speed, thereby effectively performing high-frequency vibration mixing on the medicine in the firework tube through the effect of high-speed vibration, achieving a comprehensive mixing effect of multiple materials, and improving the efficiency and uniformity of medicine mixing;

[0044] In this way, the production quality of fireworks can be effectively improved, the firing effect can be improved, and at the same time, the machine can replace manual operation. While meeting the above technical effects, it can effectively reduce human resource cost investment, reduce the production cost of fireworks, and improve the economic benefits of the enterprise, with good use effect;

[0045] After the internal medicine of the fireworks paper tube is mixed according to the preset vibration time, the rotating motor 4 stops working, and the clamping cylinder 12 and the pressing cylinder 18 drive the rod body to reset. At this time, the clamping claw 15 releases the paper tube, and the pressing cover 20 moves up;

[0046] The tertiary transfer belt 11 works to deliver the mixed firework paper tubes to the secondary conveyor belt 2, and then delivers them to the next station through the secondary conveyor belt 2 for subsequent processing.

[0047] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
