Description

Technical Field

[0001] This utility model relates to an assembly machine, and more particularly to a fireworks production paper tube assembly machine. Background Technology

[0002] Fireworks are entertainment items set off on specific occasions such as celebrations, festivals, or special events. They produce colorful and varied flames and bright effects through the combustion of gunpowder. They are typically made of a mixture of various chemical substances, including gunpowder, oxidizers, fuels, and colorants, encapsulated in paper tubes, plastic shells, or other containers, and equipped with a fuse for ignition. During combustion, fireworks release large amounts of heat, light, sound, and gases, creating dazzling visual and auditory effects and bringing joy and a celebratory atmosphere.

[0003] In the production process of fireworks paper tubes, hollow paper tubes need to be combined with paper trays to form containers for holding raw materials such as gunpowder. Traditional assembly machines usually place the paper tubes vertically and transport them by conveyor belt. After the paper tubes are injected with glue, they are assembled by pressing down on the paper trays. However, as the height of the paper tubes increases, their center of gravity also rises. During the transportation process, they are very prone to tipping over due to instability of the center of gravity. This will not only interrupt the production process, but may also damage the paper tubes, reduce production efficiency, and increase production costs.

[0004] Therefore, it is necessary to design a fireworks production paper tube assembly machine. Utility Model Content

[0005] In order to overcome the shortcomings of traditional assembly machines, which are mostly vertically placed and easily tipped over and damaged during transportation, the technical problem to be solved by this utility model is to provide a fireworks production paper tube assembly machine.

Connecting rods are rotatably connected to opposite sides of the two support platforms. The intermittent conveyor seat is rotatably connected to both support platforms via the connecting rods. A support platform is fixedly connected to one side of one support platform. A first motor is installed on the top of the support platform, and the output shaft of the first motor is connected to the connecting rod. A connecting frame is provided in the middle of the support platform. A drive mechanism and a rotating mechanism are provided on the connecting frame.

The second motor is installed on one side of the fixed base, and the output shaft of the second motor is connected to the electric push rod. A vacuum suction cup is provided at the end of the electric push rod away from the fixed base.

[0008] In a preferred embodiment of the present invention, the glue injection mechanism includes a third motor, a cylinder, and a glue injection device. The third motor is installed on one side of the connecting frame, the output shaft of the third motor is connected to the cylinder, and the glue injection device is provided on the piston rod of the cylinder.

[0009] In a preferred embodiment of the present invention, a limiting plate for limiting the paper tube is fixedly connected to one side of the top of the support platform.

[0011] In a preferred embodiment of the present invention, a baffle for limiting the paper tube is fixedly connected to the top of one of the support platforms.

Detailed Implementation

[0020] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0021] Example: A fireworks production paper tube assembly machine, such as Figures 1-4 As shown, the device includes a support platform 1, an intermittent conveyor seat 2, a first motor 4, a support platform 5, a connecting rod 7, a connecting frame 8, a vacuum suction cup 12, a glue injection device 15, a drive mechanism, and a rotating mechanism. The two support platforms 1 are rotatably connected to opposite sides by the connecting rod 7. The two support platforms 1 are rotatably connected to the intermittent conveyor seat 2 via the connecting rod 7. One support platform 1 is fixedly connected to one side of the support platform 5. The first motor 4 is mounted on the top of the support platform 5, and its output shaft is connected to the connecting rod 7. A connecting frame 8 is located in the middle of the support platform 1. The connecting frame 8 is equipped with a drive mechanism and a rotating mechanism. The connecting frame 8 is connected to a vacuum suction cup 12 for gripping the paper tray via the drive mechanism. A glue-injection device 15 for glue injection is connected via a rotating mechanism. Continuous U-shaped grooves are opened on the top of both the intermittent conveyor seat 2 and the support platform 1. Here, the two support platforms 1 are located between the pressing mechanism and the glue-injection mechanism. The first motor 4 is started, and the first motor 4 intermittently drives the output shaft to rotate. The output shaft of the first motor 4 drives the connected connecting rod 7 to rotate clockwise intermittently. The connecting rod 7 drives the connected intermittent conveyor seat 2 to rotate clockwise intermittently. When the intermittent conveyor seat 2 moves above the support platform 1, the intermittent conveyor seat 2 lifts the paper tube. When the intermittent conveyor seat 2 moves below the support platform 1, it pushes the paper tube forward and places it on the support platform 1. Thus, the paper tube is intermittently conveyed by the rotation of the intermittent conveyor seat 2 itself.

[0022] like Figure 4As shown, the tablet pressing mechanism includes a fixed base 9, a second motor 10, an electric push rod 11, and a vacuum suction cup 12. The fixed base 9 is fixedly connected to the connecting frame 8. The electric push rod 11 is rotatably connected to one end of the fixed base 9 away from the connecting frame 8. The second motor 10 is installed on one side of the fixed base 9. The output shaft of the second motor 10 is connected to the electric push rod 11. The vacuum suction cup 12 is provided at one end of the electric push rod 11 away from the fixed base 9. Here, when the electric push rod 11 is started, the telescopic rod of the electric push rod 11 extends outward. The telescopic rod of the electric push rod 11 drives the connected vacuum suction cup 12 to move downward, so that the vacuum suction cup 12 contacts the paper tray conveyed by the conveyor belt 3. Then, the vacuum suction cup 12 removes the air between the suction cup and the paper tray and adsorbs and fixes the paper tray. Subsequently, the telescopic rod of the electric push rod 11 retracts, and the vacuum suction cup 12 drives the paper tray to move upward with the telescopic rod of the electric push rod 11.

[0023] like Figure 4 As shown, the glue injection mechanism includes a third motor 13, a cylinder 14, and a glue injection device 15. The third motor 13 is installed on one side of the connecting frame 8. The output shaft of the third motor 13 is connected to the cylinder 14. The glue injection device 15 is installed on the piston rod of the cylinder 14. Here, when the cylinder 14 is started, the piston rod of the cylinder 14 extends out, and the piston rod of the cylinder 14 drives the glue injection device 15 to move towards the intermittent conveyor seat 2, so that the glue injection device 15 extends into the paper tube. Then, the third motor 13 is started, and the third motor 13 drives the output shaft to rotate. The output shaft of the third motor 13 drives the connected cylinder 14 to rotate, thereby driving the glue injection device 15 connected to the cylinder 14 to rotate and inject glue along the inner wall of the paper tube.

[0024] like Figures 1-2 As shown, a limiting plate 6 for limiting the paper tube is fixedly connected to one side of the top of the support platform 1. Here, the function of the limiting plate 6 is to limit the paper tube when the intermittent conveyor seat 2 conveys the paper tube, prevent the paper tube from deviating during the conveying process, ensure that the paper tube is in the optimal operating position, and improve the working efficiency of the device.

[0025] like Figure 1 As shown, a conveyor belt 3 for conveying the original film is provided on the side of the support platform 1 near the electric push rod 11. Here, the design of the conveyor belt 3 can realize automatic delivery of the paper tray, ensuring that the paper tray moves to the operating position with the paper tube, reducing manual intervention, and ensuring the stability and smoothness of the work.

[0026] like Figure 3 As shown, a baffle 16 for limiting the paper tube is fixedly connected to the top of one of the support platforms 1. Here, the baffle 16 is located on one side of the glue injection device 15. The design of the baffle 16 can provide support for the paper tube when the electric push rod 11 pushes the paper tray, preventing the paper tube from falling or shifting during the process of the paper tray being pushed into the paper tube, and ensuring that the assembly work is carried out smoothly.

[0027] This device is used in the fireworks production process for assembling fireworks paper tubes. When in use, the first motor 4 is started, intermittently driving the output shaft to rotate. The output shaft of the first motor 4 drives the connected connecting rod 7 to rotate intermittently clockwise. The connecting rod 7 drives the connected intermittent conveyor seat 2 to rotate intermittently clockwise. When the intermittent conveyor seat 2 moves above the support platform 1, it lifts the paper tube; when it moves below the support platform 1, it pushes the paper tube forward, placing it on the support platform 1. Thus, the paper tube is intermittently conveyed by the rotation of the intermittent conveyor seat 2 itself. When the paper tube moves to the middle of the device, cylinder 14 is activated, and the piston rod of cylinder 14 extends. The piston rod of cylinder 14 drives the glue injection device 15 to move towards the intermittent conveyor seat 2, so that the glue injection device 15 extends into the paper tube. Then, the third motor 13 is activated, and the third motor 13 drives the output shaft to rotate. The output shaft of the third motor 13 drives the connected cylinder 14 to rotate, which in turn drives the glue injection device 15 connected to cylinder 14 to rotate along the inner wall of the paper tube, so that the glue injection device 15 injects glue into the inner wall of the paper tube. After completion, the piston rod of cylinder 14 returns to the initial position, and then the electric motor is activated. The electric push rod 11 extends outward, causing the connected vacuum suction cup 12 to move downward, making it contact the paper tray conveyed by the conveyor belt 3. The vacuum suction cup 12 then extracts the air between itself and the paper tray, adsorbing and fixing the paper tray. Subsequently, the electric push rod 11 retracts, and the vacuum suction cup 12 moves the paper tray upward with the extension rod 11. Then, the second motor 10 starts, driving its output shaft to rotate. The output shaft of the second motor 10 drives the connected electric push rod 11 to move intermittently... The delivery seat 2 is rotated 90 degrees, causing the electric push rod 11 to align the paper tray adsorbed by the vacuum suction cup 12 with the paper tube. Then, the electric push rod 11 is activated again, and its telescopic rod extends. The telescopic rod of the electric push rod 11 moves the paper tray adsorbed by the vacuum suction cup 12 towards the intermittent delivery seat 2, so that the paper tray enters the paper tube and comes into contact with the glue inside the paper tube. Then, the vacuum suction cup 12 releases the paper tray, the telescopic rod of the electric push rod 11 retracts, and the telescopic rod of the electric push rod 11 drives the vacuum suction cup 12 out of the paper tube, thus completing the assembly of the fireworks paper tube.
