[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 3 This embodiment provides a handheld fireworks semi-finished product conveying device, including at least two conveyor belts 1, and a driving mechanism 2 for driving the conveyor belts 1 to rotate is connected to the conveyor belts 1. Multiple connecting plates 3 are fixed between the conveyor belts 1, and multiple clamps 4 are provided on the connecting plates 3. Two clamps 4 on the connecting plates 3 jointly clamp a handheld fireworks semi-finished product. The clamps 4 include a driving member 41 and two clamping plates 42. The driving member 41 is used to drive the two clamping plates 42 to open and close. The handheld fireworks semi-finished product conveying device also includes an opening and closing mechanism that cooperates with the driving member 41, and the opening and closing mechanism is set at the unloading station. The fixture 4 moves to the unloading station, where the opening and closing mechanism opens the two clamping plates 42 via the driver 41, allowing the semi-finished handheld fireworks to fall between the two clamping plates 42. The fixture 4 then moves away from the unloading station to transport the semi-finished handheld fireworks toward the molding station. The driver 41 recloses the two clamping plates 42 to clamp the semi-finished handheld fireworks. The conveyor belt 1 can transport multiple semi-finished handheld fireworks to the molding station, where the push-up mechanism pushes the semi-finished handheld fireworks from the fixture 4 to the molding mechanism below. The present utility model has a simple structure and, through the cooperation of the conveyor belt 1 and the fixture 4, can transport multiple semi-finished handheld fireworks to the molding station, thereby improving the production efficiency of handheld fireworks. Furthermore, through the cooperation of the opening and closing mechanism and the driver 41, the semi-finished handheld fireworks naturally fall between the clamping plates 42, effectively reducing damage to the semi-finished handheld fireworks. Specifically, the semi-finished handheld fireworks include bamboo sticks, cartridges, and double-sided tape and ignition paper attached to them.

[0024] Specifically, the clamp 4 and the conveyor belt 1 are staggered.

[0025] As another embodiment of the present invention, the clamping plate 42 is hinged on the base 43, the base 43 is fixed on the connecting plate 3, and the driving member 41 is hinged to the two clamping plates 42. The driving member 41 drives the two clamping plates 42 to open and close by the hinge.

[0026] An embodiment of the driving member 41: Figure 4 The driving member 41 includes a connecting arm 411, a first push plate 412, a push rod 413, and a spring 414. The connecting arm 411 is hinged at both ends to the clamping plate 42 and the first push plate 412, respectively. The push rod 413 passes through the spring 414, the connecting plate 3, and the base 43, and is fixedly connected to the first push plate 412. The push rod 413 is slidably connected to the base 43. The elastic force of the spring 414 drives the push rod 413 backward (away from the connecting plate 3), driving the first push plate 412 backward, thereby closing the two clamping plates 42. The opening and closing mechanism pushes the push rod 413 forward, driving the first push plate 412 forward, thereby opening the two clamping plates 42.

[0027] Specifically, the spring 414 passes through the through hole of the connecting plate 3 and is connected to the base 43 . This structural design can provide more installation space for the spring 414 .

[0028] As another embodiment of the present invention, the first push plate 412 is arranged on the side of the connecting arm 411 away from the clamping plate 42. This structural design can effectively prevent the first push plate 412 from interfering with the movement of the clamping plate 42.

[0029] As another embodiment of the present invention: Figure 3 The base 43 includes a bottom plate 431, and a protrusion 432 is provided on the side of the bottom plate 431 facing away from the connecting plate 3. The protrusion 432 is provided with an avoidance groove adapted to the clamping plate 42. The hinge shaft 433 in the avoidance groove passes through the clamping plate 42, and the clamping plate 42 rotates around the hinge shaft 433. The spring 414 passes through the through hole of the connecting plate 3 and is connected to the bottom plate 431.

[0030] An implementation manner of fixing the base 43 to the connecting plate 3: the bottom plate 431 is fixed to the connecting plate 3 by bolts.

[0031] One implementation of the opening and closing mechanism: Figure 2 The opening and closing mechanism includes a lifting cylinder 5. The piston rod of the lifting cylinder 5 is fixed with a second push plate 6 that cooperates with the push rod 413. The second push plate 6 is fixed to the piston rod. The extension of the piston rod of the lifting cylinder 5 drives the second push plate 6 forward, thereby pushing the push rod 413 forward, realizing the opening of the two clamping plates 42.

[0032] As another embodiment of the present invention: a avoidance hole is provided on the connecting plate 3 adjacent to the clamp 4 to facilitate the execution end of the ejection mechanism to pass through the avoidance hole to eject the semi-finished handheld fireworks from the clamp 4.

[0033] An embodiment of the driving mechanism 2: Figure 1 The driving mechanism 2 includes: a driving motor 21, a first synchronous wheel 22 and a synchronous belt 23. The synchronous belt 23 is arranged between the two first synchronous wheels 22, and the conveyor belt 1 is arranged between the two second synchronous wheels 8. The first synchronous wheel 22 is fixed to the second synchronous wheel 8 through the rotating shaft 7. The driving motor 21 drives the first synchronous wheel 22 to rotate, thereby driving the rotating shaft 7 to rotate. The rotation of the rotating shaft 7 drives the second synchronous wheel 8 to rotate, thereby driving the conveyor belt 1 to rotate.

[0034] Specifically, a buffer pad 9 is provided on the opposite side of the two clamping plates 42 to prevent the semi-finished handheld fireworks from being pinched.

[0035] In the present invention, the opening and closing mechanism opens the clamp 4 via the driving member 41, and the semi-finished handheld fireworks fall into the clamp 4. This unloading method is conducive to protecting the semi-finished handheld fireworks. When the clamp 4 leaves the opening and closing mechanism, the driving member 41 causes the two clamping plates 42 to close, thereby clamping the semi-finished handheld fireworks to prevent them from shifting during transportation. The conveyor belt 1 can transport multiple semi-finished handheld fireworks to the molding station, so that multiple semi-finished handheld fireworks can complete the molding process at the same time. The present invention has a simple structure, and the coordination of the clamp 4 and the conveyor belt 1 can effectively improve the transportation efficiency of the semi-finished handheld fireworks, thereby improving the production 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.
