DETAILED DESCRIPTION

[0022] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Refer to the attached Figure 1 and attached Figure 3This embodiment provides a handheld firework forming device, comprising: a clamp 1, a limiting and pressing mechanism 2, and a slidably mounted paper roll 3. The clamp 1 is connected to a rotating material pushing mechanism 4, which is used to propel the clamp 1 forward and rotate it. The limiting and pressing mechanism 2 includes an upward-facing limiting groove 21 and a pressing assembly 22 for pressing the rotating handheld firework semi-finished product. The limiting groove 21 is located between the clamp 1 and the pressing assembly 22. The paper roll 3 is provided with wrapping paper and also has a notch 31 for a cutter 5 to pass through. The cutter 5 is moved up and down by a lifting mechanism. Specifically, the wrapping paper is provided by a paper supply mechanism. The clamp 1 is an air gripper mounted on a rotary joint. The handheld firework semi-finished product includes a bamboo stick, a cartridge, and double-sided tape and ignition paper attached to the bamboo stick and cartridge. The front end of the semi-finished handheld fireworks falls onto the wrapping paper on the paper reel 3, which is adhered to the double-sided tape. The middle portion of the semi-finished handheld fireworks falls into the limiting groove 21. The clamp 1 clamps the tail of the bamboo stick, and the pressing assembly 22 presses on the top of the semi-finished handheld fireworks. The rotating pushing mechanism 4 drives the semi-finished handheld fireworks to rotate while pushing the semi-finished handheld fireworks forward, thereby wrapping the wrapping paper around the semi-finished handheld fireworks and completing the formation of the handheld fireworks. The present utility model ensures that the semi-finished handheld fireworks move linearly forward during rotation through the cooperation of the limiting groove 21 and the pressing assembly 22. This arrangement ensures the winding quality. Secondly, the limiting groove 21 and the pressing assembly 22 on the semi-finished handheld fireworks also provide a guarantee for increasing the rotation speed and movement speed, thereby improving the forming efficiency of the handheld fireworks.

[0024] One embodiment of the clamping assembly 22 includes a first rotary cylinder 221. The piston rod of the first rotary cylinder 221 is fixed with a first pressure plate 222 that cooperates with the paper reel 3. The lower end of the first pressure plate 222 is provided with a buffer layer. This buffer layer is designed to effectively prevent the crushing of the semi-finished handheld fireworks. When the clamping assembly 22 is in operation, the first pressure plate 222 rotates downward to press down on the semi-finished handheld fireworks. When the clamping assembly 22 is not in operation, the first pressure plate 222 is located outside the paper reel 3, preventing the semi-finished handheld fireworks from falling onto the paper reel 3.

[0025] As another embodiment of the present invention: the pressing assembly 22 also includes a second rotary cylinder 223, the piston rod of which is provided with a second pressing plate 224 that cooperates with the paper reel 3, a spring being provided between the second pressing plate 224 and the second rotary cylinder 223, and a first pressing plate 222 being provided between the second pressing plate 224 and the limiting groove 21. When the second pressing plate 224 rotates and presses on the semi-finished handheld fireworks, the spring can act as a buffer. When the first pressing plate 222 presses on the semi-finished handheld fireworks to complete the packaging of the cartridge, the second rotary cylinder 223 operates, and the second pressing plate 224 rotates and presses on the semi-finished handheld fireworks, cooperating with the first pressing plate 222 to wrap the wrapping paper around the bamboo stick. Compared with wrapping paper wrapped around the cartridge, this structural design enables the wrapping paper to be wrapped more tightly around the bamboo stick.

[0026] One embodiment of spring installation: The piston rod of the second rotary cylinder 223 is fixed to a connecting plate 225, on which a plurality of guide rods 226 are slidably provided. Springs are installed on the guide rods 226 between the connecting plate 225 and the pressure plate. The lower ends of the guide rods 226 are fixed to the pressure plate. The connecting plate 225 is located above the second pressure plate 224. Specifically, the connecting plate 225 is L-shaped.

[0027] As another embodiment of the present invention, the first rotary cylinder 221 and the second rotary cylinder 223 are respectively arranged on both sides of the paper reel 3. This structural design can fully utilize the space at the paper reel 3 and make the overall structure compact.

[0028] An embodiment of the sliding arrangement of the paper roll table 3: Figure 4 A guide rail is provided at the lower end of the paper reel 3, which is fixedly connected to the piston rod of the first cylinder. A paper pressing plate 6 is provided above the paper reel 3, which is fixedly connected to the piston rod of the lifting cylinder 7. When the cutter 5 moves downward to cut the wrapping paper, the paper pressing plate 6, driven by the lifting cylinder 7, presses down the wrapping paper, ensuring that the cutter 5 can cut the wrapping paper smoothly.

[0029] Specifically, the cutter 5 is located between the paper pressing plate 6 and the second pressing plate 224 .

[0030] One embodiment of the rotary pusher mechanism 4 includes a screw slider module 41 and a fixed plate 42. The fixed plate 42 is fixedly connected to the slider of the screw slider module 41. The fixed plate 42 is provided with a rotating assembly, and the fixture 1 is mounted on the rotating assembly. The screw slider module 41 and the fixed plate 42 can simultaneously drive multiple rotating assemblies to move horizontally.

[0031] One embodiment of the rotating assembly: The rotating assembly includes a first drive motor 43, a first rotating shaft 44, and multiple commutators 45. The output shaft of the first drive motor 43 is fixed to the first rotating shaft 44, and the commutator 45 is disposed on the first rotating shaft 44. The fixture 1 is fixed to the commutator 45. The commutator 45 includes a first bevel gear and a second bevel gear. The first bevel gear is fixed to the first rotating shaft 44, and the second bevel gear is fixed to the rotating shaft. The fixture 1 is fixed to the rotating shaft via a rotary joint. In this structural design, the first drive motor 43 can drive the rotation of multiple fixtures 1.

[0032] As another embodiment of the present invention, this embodiment further includes an auxiliary discharge mechanism 8, which is located directly in front of the limiting groove 21. When the rotating push mechanism 4 pushes the bamboo stick cartridge to complete wrapping paper, the clamp 1 releases the bamboo stick, and the auxiliary discharge mechanism 8 continues to push the handheld firework forward until the handheld firework leaves the paper reel 3.

[0033] An embodiment of the auxiliary discharging mechanism 8: Figure 2 The auxiliary discharge mechanism 8 includes a second drive motor 81, a second rotating shaft 82, and multiple pulleys 83. The pulleys 83 are fixed to the second rotating shaft 82, which is in turn fixed to the output shaft of the second drive motor 81. After the handheld firework is wrapped with wrapping paper, the fixture 1 releases the bamboo stick. The front end of the handheld firework is now on the pulleys 83. The rotating pulleys 83 continue to drive the handheld firework forward until it leaves the paper reel 3.

[0034] Specifically, a slide is provided on the paper rolling table 3, and the wrapping paper slides along the slide. The paper pressing plate 6 is arranged above the slide. A limit plate is provided above the slide near the cutter 5, which can effectively prevent the wrapping paper from falling off the slide when feeding paper to the bamboo sticks and the medicine cartridge.

[0035] In the present invention, the paper reel 3 slides forward, and the front end of the semi-finished handheld firework falls onto the wrapping paper on the paper reel 3, while the middle portion falls into the limiting groove 21. The wrapping paper is adhered to the double-sided tape, and the clamp 1 clamps the tail of the bamboo stick. The paper reel 3 slides backward, and the first pressing plate 222 rotates and presses down on the semi-finished handheld firework. The rotary pushing mechanism 4 rotates the semi-finished handheld firework while pushing the semi-finished handheld firework forward, wrapping the wrapping paper around the semi-finished handheld firework. When the cartridge is wrapped, the paper pressing plate 6 presses the wrapping paper, and the cutter 5 cuts the wrapping paper. The second pressing plate 224 rotates and presses down on the semi-finished handheld firework, and together with the first pressing plate 222, presses the bamboo stick, thereby wrapping the wrapping paper more tightly around the stick. When the wrapping paper is completely wrapped, the clamp 1 releases the bamboo stick, completing the handheld firework. The present invention ensures that the semi-finished handheld fireworks product moves linearly forward during rotation through the cooperation of the limiting groove 21 and the pressing assembly 22. This arrangement ensures the winding quality. Secondly, the restriction of the semi-finished handheld fireworks product by the limiting groove 21 and the pressing assembly 22 can also provide a guarantee for the improvement of the rotation speed and the movement speed, thereby helping to improve the molding efficiency of the handheld fireworks.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
