Description

Technical Field

[0001] The utility model relates to the technical field of fireworks production, in particular to an automatic quantitative feeding device for sealing fireworks. Background Art

[0002] The inner tube of a fireworks tube is usually sealed with paper shells. However, the paper shells may not be sealed tightly, which will affect the effect of the fireworks inner tube exploding in the air. The yellow mud seal can ensure that the inner tube is sealed intact and can be fully exploded, thereby improving the viewing experience of the fireworks.

[0003] In the prior art, the patent with authorization publication number CN 220103904 U discloses an inner tube sealing agent machine for combined fireworks production, which places the suction pipe of the pump machine in the sealing agent container to be used, starts the pump machine to suck in the sealing agent, places the fireworks tube to be sealed on the fireworks tube placement plate, and transports the fireworks tube placement plate through a conveyor belt. When it reaches the bottom of the injection plate, the injection plate is manipulated to fall so that the injection port is aligned with the fireworks tube. At this time, the sealing agent passes through the feed pipe and flows into the injection plate and finally enters the fireworks tube through the injection port to complete the sealing work. The pump machine cannot perform quantitative delivery when conveying the sealing agent, and workers need to observe whether the injection is complete, which is time-consuming and labor-intensive. At the same time, due to the inconsistent quality of the injected sealing agent, it is easy to affect the quality of fireworks production. Utility Model Content

[0021] The driving mechanism 3 includes a servo motor 31, a worm 32 and a worm gear 33. The worm 32 is rotatably mounted on the bracket of the frame 1. The servo motor 31 is mounted on the top of the bracket of the frame 1. The output shaft of the servo motor 31 is fixedly connected to the end of the worm 32. The worm gear 33 is sleeved and fixed on the discharge tray 9. The worm 32 is engaged with the worm gear 33. The servo motor 31 is electrically connected to the PLC controller 2. The output shaft of the servo motor 31 drives the worm 32 to rotate. The worm 32 is engaged with the worm gear 33. The worm gear 33 drives the discharge tray 9 to rotate. The discharge tray 9 rotates relative to the barrel 7 through the bearing 8, thereby allowing the sealing agent to enter the inlet position of the pump 11, and then the pump 11 injects the sealing agent into the fireworks tube in a quantitative manner through the injection tube 12. The sealing agent is placed in the injection metering groove 10 in a quantitative manner, and then the sealing agent in the injection metering groove 10 is injected into the fireworks tube by the pump 11. This avoids the trouble of workers observing the injection amount, saving time and effort.

[0022] The push rod driving mechanism 4 includes a mounting seat 44, a slide 45, a connecting frame 46 and a slider 47. The push rod 13 is fixed on the connecting frame 46, and the slider 47 is fixed to the end of the connecting frame 46. The slider 47 is slidably connected to the slide 45. The slide 45 is opened on the mounting seat 44, and the mounting seat 44 is fixed on the inner side of the frame 1. The push rod driving mechanism 4 also includes a connecting seat 43, a first hinge 48, a connecting rod 49 and a second hinge 410. One end of the connecting rod 49 is hinged to the slider 47 through the first hinge 48, and the other end of the connecting rod 49 is hinged to the connecting seat 43 through the second hinge 410. The push rod driving mechanism 4 also includes an electric push rod 41 and a rotary joint 42. The electric push rod 41 is installed on the side of the frame 1. The telescopic end of the electric push rod 41 is rotatably connected to the connecting seat 43 through the rotary joint 42. The electric push rod 41 is electrically connected to the PLC control Device 2, the rotary joint 42 can make the telescopic end of the electric push rod 41 and the connecting seat 43 rotate relative to each other as the unloading tray 9 rotates. When the injection amount of the sealing agent needs to be adjusted, the telescopic end of the electric push rod 41 drives the connecting seat 43 to perform telescopic movement, and the connecting seat 43 drives the slider 47 to slide along the slide groove 45 through the connecting rod 49. At this time, the connecting seat 43 rotates relative to the slider 47 through the first hinge 48, and the connecting seat 43 rotates relative to the connecting seat 43 through the second hinge 410. The slider 47 drives the ejector rod 13 to move through the connecting frame 46, and the ejector rod 13 slides relative to the injection dosage groove 10, thereby adjusting the capacity of the injection dosage groove 10, thereby meeting the corresponding production needs. It is easy to adjust, and the capacity of multiple injection dosage grooves 10 can be adjusted at a time, thereby meeting the corresponding production needs.

[0023] The working principle of the automatic quantitative discharge device for sealing fireworks provided by the present invention is as follows: the hopper 6 is used to hold the sealing agent, and the vibration motor 5 vibrates the hopper 6, so that the sealing agent in the hopper 6 falls into the injection dosage groove 10 on the discharge tray 9. Then, the output shaft of the servo motor 31 drives the worm 32 to rotate, the worm 32 engages with the worm gear 33, and the worm gear 33 drives the discharge tray 9 to rotate. The discharge tray 9 rotates relative to the barrel 7 through the bearing 8, so that the sealing agent enters the inlet position of the pump 11, and then the pump 11 injects the sealing agent into the fireworks tube in a quantitative manner through the injection pipe 12. When the injection amount of the sealing agent needs to be adjusted, the telescopic end of the electric push rod 41 drives the connecting seat 43 to perform telescopic movement, and the connecting seat 43 drives the slider 47 to slide along the slide groove 45 through the connecting rod 49. At this time, the connecting seat 43 rotates relative to the slider 47 through the first hinge 48, and the connecting seat 43 rotates relative to the connecting seat 43 through the second hinge 410. The slider 47 drives the push rod 13 to move through the connecting frame 46, and the push rod 13 slides relative to the injection dosage groove 10, thereby adjusting the capacity of the injection dosage groove 10 to meet the corresponding production needs.
