Technical Field

[0001] This utility model relates to the field of fireworks production technology, and in particular to a paper tube stacking device. Background Technology

[0002] Fireworks are a traditional type of fireworks, typically used to celebrate festivals, ceremonies, and other special occasions. The production and use of fireworks have a long history. Fireworks are basically composed of components such as paper tubes, fuses, and fuses. After the paper tubes are made, they need to be stacked according to certain rules. The stacking of firework paper tubes is very important for saving storage space, facilitating transportation, and improving production efficiency.

[0003] Currently, when stacking individual firework paper tubes, they are usually placed on racks for storage to maximize storage space utilization. Stacked firework paper tubes are also easy to handle and manage, which helps improve logistics efficiency in the production process. However, the placement surface of existing devices is mostly a flat structure. In the early stages, when placing a small number of firework paper tubes, it is difficult to limit their movement. The firework paper tubes are prone to rolling on the placement surface, causing them to become skewed and affecting the stacking quality.

[0004] Therefore, in order to address the above problems, a paper tube stacking device has been developed that can limit the placement of a small number of firework paper tubes, prevent the paper tubes from rolling and causing skewing, and ensure the stacking quality. Utility Model Content

[0005] To overcome the shortcomings of existing devices that are difficult to limit when placing a small number of firework paper tubes, causing the paper tubes to roll on the placement surface and become skewed, thus affecting the stacking quality, this utility model provides a paper tube stacking device that can limit the placement of a small number of firework paper tubes, prevent the paper tubes from rolling and becoming skewed, and ensure the stacking quality.

[0006] The technical solution is as follows: A paper tube stacking device includes a base, a back plate, an upper plate, a lower plate, a first torsion spring, a rotating component, a second torsion spring, a locking pin, and a spring. The back plate is connected to the base. The upper plate is symmetrically connected to the left and right sides of the upper front side of the back plate. The lower plate is rotatably connected to the lower part of each upper plate. The lower plate is connected to the adjacent upper plate by a first torsion spring. The rotating component is rotatably connected to the lower front side of the lower part of the right lower plate. The rotating component is connected to the right lower plate by a second torsion spring. The rotating component is slidably connected to a locking pin. The locking pin is connected to the rotating component by a spring.

[0007] Optionally, it also includes push rods, with push rods connecting the upper plate to the base on each of the non-adjacent sides.

[0008] Optionally, it also includes a handle, with a handle attached to the front side of the lower plate.

[0009] Optionally, it also includes casters, with multiple casters rotatably connected to the underside of the base.

[0010] Optionally, it also includes a storage box, a rain curtain, a support component, and a limiting component. The storage box is connected to the front of the base, and the rain curtain is rolled up inside the storage box. Support components are connected to both the left and right sides of the base, and the end of the rain curtain is snapped into the support component. Limit components are connected to the upper rear side of the upper plate.

[0011] Optionally, both the support and the limiting components are arc-shaped structures.

[0012] The beneficial effects of this utility model are as follows: 1. This utility model allows the lower plate to rotate on the upper plate by pulling it until both lower plates are tilted and the lower parts of the lower plates are closed. The lower plate is fixed and limited by locking pins that engage with the lower plate on the left. This can limit the placement of a small number of firework paper tubes, prevent the firework paper tubes from rolling and causing tilting, and ensure the stacking quality.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0021] A paper tube stacking device, such as Figures 1-5 As shown, the device includes a base 1, a back plate 2, an upper plate 3, a lower plate 4, a first torsion spring 5, a rotating component 9, a second torsion spring 10, a locking pin 11, and a spring 12. The back plate 2 is connected to the base 1. The upper plate 3 is symmetrically connected to the upper front side of the back plate 2. The lower plate 4 is rotatably connected to the lower part of each upper plate 3. The lower plate 4 is connected to the adjacent upper plate 3 by a first torsion spring 5. The lower front side of the lower plate 4 on the right side is rotatably connected to a rotating component 9. The second torsion spring 10 connects the rotating component 9 to the lower plate 4 on the right side. A locking pin 11 is slidably connected to the rotating component 9. A spring 12 connects the locking pin 11 to the rotating component 9. Under the action of the spring 12, the locking pin 11 is first engaged with the lower plate on the left side. 4. The lower plates 4 are tilted and closed at the bottom. Firework paper tubes are then stacked between the lower plates 4. The tilted lower plates 4 limit the small number of firework paper tubes stacked earlier to prevent them from rolling and tilting. After a certain number of firework paper tubes are stacked between the lower plates 4, the locking pin 11 is pulled forward to disengage it from the lower plate 4 on the left. The spring 12 is stretched and driven to rotate the rotating part 9 clockwise under the action of the second torsion spring 10. Then, the lower plates 4 rotate and open under the action of gravity and the first torsion spring 5, so that the lower plates 4 are in a vertical state. The firework paper tubes between the lower plates 4 automatically roll down to the base 1 for stacking.

[0022] It also includes push rods 6. Push rods 6 are connected to the base 1 on both sides of the upper plate 3, which are not adjacent to each other. Push rods 6 provide a gripping position for the operator, making it easier for the operator to move the stacked firework paper tubes.

[0023] It also includes a handle 7. The front side of the lower plate 4 is connected to a handle 7, which provides a gripping position for the operator to pull the lower plate 4 to rotate.

[0024] It also includes casters 8. Four casters 8 are rotatably connected to the underside of the base 1, making it easy for operators to move the base 1.

[0025] It also includes a storage box 13, a rain curtain 14, a support member 15, and a limiting member 16. The storage box 13 is connected to the front of the base 1, and the rain curtain 14 is rolled up inside the storage box 13. The support members 15 are connected to both the left and right sides of the base 1. The end of the rain curtain 14 is engaged with the support member 15. The upper rear side of the upper plate 3 is connected to the limiting member 16. When the rain curtain 14 is needed, the end of the rain curtain 14 is removed from the support member 15 and pulled to engage with the limiting member 16. Next, the rain curtain 14 covers the stacked firework paper tubes to prevent rainwater from wetting them during transportation. It also limits and blocks the stacked firework paper tubes to prevent them from sliding forward from the base 1 during transportation. When the rain curtain 14 is not needed, the end of the rain curtain 14 is detached from the limiting member 16, and the rain curtain 14 is rolled up by the storage box 13. Finally, the end of the rain curtain 14 is secured and supported by the support member 15.

[0026] In use, this utility model first requires pushing the push rod 6 to move it to the fireworks paper tube stacking area under the action of the universal wheel 8. Then, the operator pulls the lower plate 4 to make it rotate on the upper plate 3. The first torsion spring 5 deforms under force until the lower plate 4 is tilted and the lower part of the lower plate 4 is closed. Next, the locking pin 11 is pulled forward, the spring 12 is stretched, and the rotating part 9 rotates counterclockwise. The second torsion spring 10 deforms under force, and then the locking pin 11 is engaged with the lower plate 4 on the left under the action of the spring 12, thereby fixing and limiting the lower plate 4. Firework paper tubes are then stacked between the lower plates 4. The tilted lower plate 4 limits the small number of fireworks paper tubes stacked in the early stage, preventing the fireworks paper tubes from rolling and causing tilting. After a certain number of fireworks paper tubes are stacked between the lower plates 4, the locking pin 11 is pulled forward again to disengage it from the lower plate 4 on the left. The spring 12 is stretched under force. Under the action of the second torsion spring 10, the rotating part 9 rotates clockwise. At this time, the lower plate 4 rotates and opens under the action of gravity and the first torsion spring 5, so that the lower plate 4 is in a vertical state. The firework paper tubes between the lower plates 4 automatically roll down to the base 1 for stacking. After stacking, the firework paper tubes can be transported and transferred. If the rain curtain 14 is needed during the transport process, the end of the rain curtain 14 can be removed from the support 15 and the end of the rain curtain 14 can be pulled to engage with the limiting part 16. The rain curtain 14 covers the stacked firework paper tubes to prevent rainwater from wetting the firework paper tubes during the transport process. It can also limit and block the stacked firework paper tubes to prevent the stacked firework paper tubes from sliding forward from the base 1 during the transport process. When the rain curtain 14 is not needed, the end of the rain curtain 14 is detached from the limiting part 16 and the rain curtain 14 is rolled up by the storage box 13. Finally, the end of the rain curtain 14 is engaged and supported by the support 15.
