[0001] The utility model relates to the technical field of firework tube production, in particular to a firework tube conveying device. Background Art
[0002] Fireworks, made from pyrotechnic powder and used to create sounds, lights, and colors, are entertainment products. First invented by Chinese working people, they are often used in grand ceremonies and performances. Today, my country boasts thousands of fireworks factories, employing millions, and produces 45 million boxes annually, nearly 40% of which is exported, representing half of global fireworks sales.
[0003] In the fireworks production process, the transportation of fireworks tubes is an indispensable part. After the fireworks gunpowder filling is completed, it is usually necessary to put it into the lower hopper and wait to be transported by the conveyor belt. However, when entering the lower hopper, the falling channel at the bottom is too narrow, and there is a risk of the material being blocked here. The fireworks tubes are large in size, and the traditional anti-blocking mechanism is no longer applicable. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a firework tube conveying device, including a conveying mechanism, a pair of support rods are fixedly connected to the outer end of the conveying mechanism, a feed hopper is fixedly connected between the pair of support rods, a material blocking component is arranged in the feed hopper, and the material blocking component includes a pair of material blocking plates. When the pair of material blocking plates are working, one of them will always be tilted upward and the other will be tilted downward, and they will switch back and forth to freely switch the channel for the material to fall.
[0006] As a further description of the above technical solution: the material blocking component includes a pair of rotating drums, both ends of the rotating drums are fixedly connected to rotating rods, the outer end of the feed hopper is fixedly connected to a bearing sleeve, and the rotating rod is rotatably connected to the inside of the bearing sleeve.
[0007] As a further description of the above technical solution: a driving component is provided on the material blocking component, and the driving component includes a bending rod, and the two ends of the bending rod are fixedly connected with a first push rod and a second push rod, and the outer ends of a pair of rotating rods are respectively fixedly connected with a first driving plate and a second driving plate.

[0008] As a further description of the above technical solution: a pushing component is also provided on the material blocking component, and the pushing component includes a pushing plate. A guide hole is provided on the feed hopper, and a pair of sliding rods are fixedly connected to the end of the pushing plate.

[0009] As a further description of the above technical solution: the push plate is arranged at an angle, and an elastic material is provided on the push plate to buffer the material when it is squeezed.
[0010] As a further description of the above technical solution: the guide rod has an arc-shaped structure, and a pair of pins are fixedly connected to the inner wall of the feed hopper, and the pins are rotatably connected to the push plate.
[0011] The utility model provides a fireworks tube conveying device, which has the following beneficial effects:
[0012] 1. By setting a driving component, a pair of material blocking plates can be driven to swing back and forth, so that there is always one material blocking plate tilted upward and the other tilted downward. When the left material blocking plate tilts downward and the right material blocking plate tilts upward, a passable channel will be formed on the left side of the feed hopper, and the material on the left side will fall in sequence. Then switch to the left material blocking plate tilting upward and the right material blocking plate tilting downward.

In this way, orderly material drop can be achieved, and the material accumulation at the bottom of the feed hopper can be effectively avoided.
[0013] 2. By setting a rotatable push plate, the end of the slide rod slides up and down inside the bending plate during its movement, and the push plate swings back and forth with the pin as the axis, further converting the thrust of the material into an upward thrust, effectively avoiding damage to the material during the dredging of the hopper.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0024] Example 1
[0025] Reference Figure 1 A fireworks tube conveying device includes a conveying mechanism 1, which includes a reduction motor and a conveyor belt fixedly connected to the output end of the reduction motor, and a support frame responsible for supporting the conveyor belt. The outer end of the conveying mechanism 1 is fixedly connected to a pair of support rods 2, and a feed hopper 3 is fixedly connected between the pair of support rods 2. The feed hopper 3 includes a material storage part and a material drop part. A material blocking component 4 is arranged in the feed hopper 3. The material blocking component 4 includes a pair of material blocking plates 5. When the pair of material blocking plates 5 are working, one of them will always be tilted upward and the other will be tilted downward, and they will switch back and forth to freely switch the channel for the material to fall.
[0026] When the feed hopper 3 is full of materials (the materials in this case refer to fireworks tubes), the cross-sectional areas of the storage part and the discharge part are too different, resulting in the risk of material being blocked in the discharge part. Therefore, it is necessary to limit a passage allowed to pass through inside. When the left-side material blocking plate 5 tilts downward and the right-side material blocking plate 5 tilts upward, the feed hopper 3 will form a passable passage on the left side, and the materials on the left side will fall in sequence. Then, the left-side material blocking plate 5 will be switched to tilt upward and the right-side material blocking plate 5 will be tilted downward. The subsequent materials that fall on the left side will be blocked by the left-side material blocking plate 5, so that they are all located above the left-side material blocking plate 5, waiting for the next material dropping. In this way, orderly material dropping can be achieved, and the accumulation of materials at the bottom of the feed hopper 3 can be effectively avoided.
[0027] Reference Figure 2-3 As the preferred technical solution of this embodiment, the material blocking component 4 includes a pair of rotating drums 6, both ends of which are fixedly connected to rotating rods 7, and the outer end of the feed hopper 3 is fixedly connected to a bearing sleeve 8 to reduce the friction of rotation. The rotating rod 7 is rotatably connected to the inside of the bearing sleeve 8.
[0028] As the preferred technical solution of this embodiment, a driving component 9 is provided on the material blocking component 4, and the driving component 9 includes a bending rod 10, and the two ends of the bending rod 10 are fixedly connected with a first push rod 11 and a second push rod 12, and the outer ends of a pair of rotating rods 7 are respectively fixedly connected with a first driving plate 13 and a second driving plate 14. During the reciprocating motion of the bending rod 10, the first driving plate 13 and the second driving plate 14 are driven to swing back and forth.
[0029] Specifically, the side end of the bending rod 10 is also fixedly connected to a hydraulic cylinder 20 (the power can also be replaced by manual drive). The hydraulic cylinder 20 is electrically connected to the controller. By setting the hydraulic cylinder 20, the bending rod 10 can be driven to reciprocate, and the movement interval time can be freely adjusted according to the controller.
[0030] In order to achieve the free switching of the above-mentioned material blocking component 4, a driving component 9 can be set up, and the reciprocating motion of the bending rod 10 is used to move the first push rod 11 and the second push rod 12, so that the first drive plate 13 and the second drive plate 14 swing, thereby achieving the left and right material blocking plates 5 to tilt upward alternately (the optimal tilt angle is perpendicular to the inner wall of the feed hopper).
[0031] Reference Figure 4 As the preferred technical solution of this embodiment, a pushing component 15 is also provided on the material blocking component 4, and the pushing component 15 includes a pushing plate 16. A guide hole 17 is provided on the feed hopper 3. The end of the pushing plate 16 is fixedly connected to a pair of sliding rods 18. The sliding rods 18 are slidably connected to the inside of the guide hole 17, and the end of the sliding rod 18 is movable through the inside of the bending rod 10.
[0032] In order to prevent the material on the right from sliding to the left when the left channel is opened, a push plate 16 can be provided as a barrier, which can also expand the space of the left channel and make the falling more smooth.
[0033] As a preferred technical solution of this embodiment, the push plate 16 is arranged at an angle, and elastic material is provided on the push plate 16 to cushion the material when it is squeezed.
[0034] In order to avoid squeezing the material, the push plate 16 can be appropriately tilted, with an inclination angle of 10-80 degrees, so that the push plate 16 exerts an upward thrust in the process of pushing the material to move, and the material will also tend to move upward, effectively avoiding the materials from being squeezed against each other and damaged.
[0035] Example 2
[0036] Reference Figure 5 The difference between this embodiment and the first embodiment is that the following technical features are added: the guide rod has an arc-shaped structure, a pair of pins 19 are fixedly connected to the inner wall of the feed hopper 3, and the pins 19 are rotatably connected to the push plate 16. In this embodiment, the gap between the bending rod 10 and the sliding rod 18 is larger, allowing the sliding rod 18 to slide up and down inside it.
[0037] To further prevent the push plate 16 from pressing the material when it moves, the end of the slide rod 18 slides up and down inside the bending rod 10 during its movement, and the push plate 16 swings back and forth with the pin 19 as the axis, further converting the thrust of the material into an upward thrust, effectively avoiding damage to the material during the process of clearing the feed hopper 3.

Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
