[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 2The present embodiment provides a double-sided tape binding device for semi-finished handheld fireworks, comprising a turntable 1, a drive motor 2 for starting the rotation of the turntable 1 being connected to the turntable 1, two shafts 3 being fixed to the turntable 1, the two shafts 3 being symmetrically distributed along the axis of the turntable 1, a roller 4 being provided for the rotation of the shaft 3, an anti-sticking layer 5 being provided on the outer side of the roller 4, the distance between the two rollers 4 being no greater than the width of the semi-finished handheld fireworks, generally the diameter of the bamboo stick 12 being smaller than the diameter of the cartridge 13, and therefore the distance between the two rollers 4 being no greater than the diameter of the bamboo stick 12; the roller 4 being made of an elastic material. The semi-finished handheld fireworks comprise a bamboo stick 12, a cartridge 13 and double-sided tape 14 attached to the bamboo stick 12 and the cartridge 13. In the present utility model, with reference to the attached drawings, Figure 4 , the handheld fireworks semi-finished product is transferred between the two rollers 4, and the double-sided tape 14 on the bamboo stick 12 and the medicine cartridge 13 is blocked by the rollers 4, and the two ends of the double-sided tape 14 are located on the outside of the rollers 4; at this time, the handheld fireworks semi-finished product is roughly located on the axis of the turntable 1, and the drive motor 2 drives the turntable 1 to rotate one circle, and the two rollers 4 rotate around the handheld fireworks semi-finished product. During the rotation process, one roller 4 wraps the double-sided tape 14 around the bamboo stick 12 and the medicine cartridge 13 to complete the binding, and the other roller 4 supports the handheld fireworks semi-finished product, so that the posture of the handheld fireworks semi-finished product remains stable when the double-sided tape 14 is wrapped. This structural design can effectively ensure the quality of the double-sided tape 14 wrapping. Secondly, the elastically designed roller 4 will not squeeze the handheld fireworks semi-finished product when rotating around it. The anti-sticking layer 5 design can effectively prevent the double-sided tape 14 from sticking to the roller 4 during the wrapping, thereby avoiding affecting the binding effect.

[0024] As another embodiment of the present invention: Figure 3 This embodiment further includes a positioning mechanism 6 for positioning the two rollers 4. When activated, the positioning mechanism 6 is used to position the rollers 4 so that the two rollers 4 are arranged in an upper and lower position so that the semi-finished handheld fireworks can be transferred between the two rollers 4.

[0025] One embodiment of positioning mechanism 6: Positioning mechanism 6 is a proximity switch. The object to be detected by the proximity switch is aligned with the two shafts 3. When the proximity switch senses the object to be detected, it controls the drive motor 2 to stop. At this point, the object to be detected and the two shafts 3 are aligned with a straight line L, and line L is perpendicular to the horizontal plane.

[0026] One installation method of the object to be detected: a rotating shaft 7 is fixed on the turntable 1, a mounting tube 8 is fixed on the rotating shaft 7, the mounting tube 8 and the shaft 3 are respectively located on both sides of the turntable 1, and the object to be detected is threadedly connected to the mounting tube 8.

[0027] As another embodiment of the present invention: the thickness of the roller 4 is consistent with the width of the double-sided tape 14. This structural design can effectively wrap the double-sided tape 14 around the bamboo stick 12 and the cartridge 13, avoiding being affected by the ignition paper near the double-sided tape 14, thereby ensuring the binding effect.

[0028] As another embodiment of the present invention, a synchronous belt is provided between the output shaft of the driving motor 2 and the rotating shaft 7. This arrangement enables the driving motor 2 and the rotating shaft 7 to be arranged side by side, thereby fully utilizing the space in the length direction of the frame.

[0029] As another implementation of the present invention: this embodiment further includes a protective shell 9, and the synchronous belt is located inside the protective shell 9. This structural design is conducive to improving safety.

[0030] As another embodiment of the present invention, a coupling 10 is provided between the rotating shaft 7 and the synchronous belt.

[0031] As another embodiment of the present invention: a bearing 11 is provided between the drum 4 and the shaft 3 , and the shaft 3 is provided with baffles at both ends of the drum 4 .

[0032] Specifically, the roller 4 is made of sponge.

[0033] The present invention has a simple structure. A semi-finished handheld firework is transferred between two rollers 4. A drive motor 2 then drives the two rollers 4 to rotate around the semi-finished handheld firework. During the rotation of the two rollers 4, the semi-finished handheld firework is positioned. Simultaneously, one roller 4 wraps double-sided tape 14 around a bamboo stick 12 and a cartridge 13, automatically binding the bamboo stick 12 and cartridge 13 with the double-sided tape 14. This process is highly efficient. Furthermore, the design of the elastic material and the anti-sticking layer 5 facilitate the binding effect of the double-sided tape 14.

[0034] 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.
