[0032] It should also be understood that the terms used in this description of the embodiments of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the embodiments of the present invention. As used in the description of the embodiments of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms of "a", "an" and "the" are intended to include plural forms.

[0033] The specific embodiment of the present invention is shown in the accompanying drawings, which is a new type of fully automatic firecracker edge heat shrink packaging integrated forming machine, including a frame 1, on which a reel assembly 2 is provided, and the reel assembly 2 is used to roll long strips of firecrackers into a disc; it also includes a film coating assembly 3, a conveying assembly 4 and a heat shrink molding assembly;

[0034] The film coating assembly 3 is used to coat the disc-shaped fireworks with a thermoforming film;

[0035] The conveying assembly 4 is used to convey the disc-shaped fireworks coated with the thermoforming film to the interior of the thermoforming assembly for thermoforming;

[0036] The thermoforming assembly includes a forming box 5, a preforming mechanism and a post-forming mechanism. The forming box 5 is arranged on the frame 1. The preforming mechanism and the post-forming mechanism are arranged in the forming box 5 in sequence. The preforming mechanism is used to preform the thermoforming film on the disc-shaped firecracker.

[0037] In the above scheme, by setting up a thermoforming component, the preforming mechanism in the thermoforming component can preform the thermoforming film on the disc-shaped firework and can flatten the disc-shaped firework before forming, so that the surface is relatively flat after heat shrinkage is completed.

[0038] The preforming mechanism includes a conveyor belt 24, a hot air component, an axial flattening component and a circumferential flattening component. The axial flattening component is used to flatten the axial direction of the disc-shaped fireworks, the circumferential flattening component is used to flatten the circumferential surface of the disc-shaped fireworks, and the hot air component is used to blow hot air onto the thermoforming film of the disc-shaped fireworks to preform the thermoforming film. Furthermore, the axial flattening component includes a mounting rod 11, a movable rod 12, a flattening disk 17 and a driving member 1. The molding box 5 is provided with a mounting cavity 18 for installing the preforming mechanism. The mounting rod 11 is vertically arranged in the mounting cavity 18. The movable rod 12 is movably arranged at the lower end of the mounting rod 11. The flattening disk 17 is arranged at the lower end of the movable rod 12. The driving member 1 is used to drive the movable rod 12 to move relative to the mounting rod 11.

[0039] In this embodiment, further, the driving member 1 includes a thermo-elastic ring 13 and a spring 14, a limit ring 19 is provided on the movable rod 12, the thermo-elastic ring 13 is sleeved on the movable rod 12 and one end of the thermo-elastic ring 13 abuts against the upper end surface of the limit ring 19, and the other end abuts against the lower end surface of the mounting rod 11, and one end of the spring 14 is fixedly connected to the upper end surface of the limit ring 19, and the other end is fixedly connected to the lower end surface of the mounting rod 11. The thermo-elastic ring 13 is made of titanium alloy memory material. The thermo-elastic ring made of titanium alloy memory material will undergo axial deformation after being heated.

[0040] It should be noted that, in order to enable the thermostrictive ring to deform in time, an air outlet pipe 10 facing the thermostrictive ring 13 is provided on the hot air component.

[0041] In the present embodiment, specifically, the circumferential leveling component includes a plurality of clamping structures, and a plurality of the clamping mechanisms are installed in a circular array on the lower end surface of the leveling disk 17. Furthermore, the clamping structure includes a driving member 23, a clamping rod 18 and a connecting rod 20. The driving member 23 is fixedly installed on the lower end surface of the leveling disk 17. One end of the connecting rod 20 is connected to the clamping rod 18. One end of the clamping rod 18 is hingedly installed on the lower end surface of the leveling disk 17 through a hinge shaft 21. One end of the connecting rod 20 away from the clamping rod 18 is hingedly connected to the driving member 23. The clamping rod 18 is an arc-shaped rod adapted to the shape of the outer circumference of the disc-shaped firecracker. The driving member 23 is a long strip rod supported by a titanium alloy memory material. The state of the clamping rod in a normal state is as follows: Figure 6 As shown, when the driving member 2 is subjected to the hot air, it undergoes axial deformation and drives the clamping rod to rotate to clamp the outer circumference of the disc-shaped firework (such as Figure 5 shown).

[0042] In this embodiment, further, the hot air component includes a hot air main pipe 6, a hot air branch pipe 9 and an annular air outlet pipe 16, one end of the hot air main pipe 6 is connected to the hot air source, one end of the hot air branch pipe 9 is connected to the hot air main pipe 6, and the other end is connected to the annular air outlet pipe 16, and a plurality of air outlets 15 are evenly distributed at the lower end of the annular air outlet pipe 16, and ventilation holes 22 are provided at positions on the leveling rod corresponding to the air outlets 15 and the second driving member 23.

[0043] In the above scheme, when the sensor senses that the coiled disc-shaped fireworks are transported to the bottom of the leveling plate through the conveyor belt 24, the conveyor belt stops working, and then the hot air source starts to provide hot air to the hot air main pipe and the hot air branch pipe. A part of the hot air is first blown out from the air outlet pipe, causing the thermoplastic ring to axially deform, driving the movable rod and the leveling plate to press down on the disc-shaped fireworks, and axially leveling the disc-shaped fireworks. Another part of the hot air is blown out from the air outlet on the annular air outlet pipe, blown onto the driving member 2 through the ventilation hole, causing the driving member 2 to axially deform, driving the clamping rod to rotate around the hinge shaft and then clamping the outer circumference of the disc-shaped fireworks (such as Figure 5 As shown), at the same time, under the action of hot air, the heat shrink film is pre-shrunk. After reaching the specified time (3S), the hot air source stops working. After the hot air loses its effect, the thermo-elastic ring and the second driving member are reset, and the conveyor belt restarts to transport the pre-shrunk disc-shaped fireworks to the post-forming mechanism for the final heat shrinkage treatment. This solution uses a pre-forming mechanism to pre-shrunk the disc-shaped fireworks and the heat shrink film, which can effectively flatten the disc-shaped fireworks before forming, so that the surface is relatively flat after the heat shrinkage is completed. At the same time, the hot air used for pre-shrunk is used to drive the axial flattening component and the circumferential flattening component, and the positioning of the disc-shaped fireworks can be automatically canceled after the pre-shrunk is completed.

[0044] In this embodiment, it should be noted that the post-forming mechanism includes an installation cavity 25 and a heating plate 7. A partition is provided between the installation cavity 2 and the installation cavity 1. The disc-shaped fireworks and the heat shrinkable film after pre-forming and heat shrinking enter the installation cavity 2, and the final heat shrinkage forming is completed under the heating action of the heating plate.

[0045] It should be noted that the reel assembly, film coating assembly and conveying assembly in this embodiment belong to the prior art, and those skilled in the art can select and design them from the prior art, so they will not be described in detail in this embodiment.

[0046] The above description is only for the best embodiment of the present invention, but it should not be understood as limiting the claims. The present invention is not limited to the above embodiments, and its specific structure is allowed to be changed. All changes made within the scope of protection of the independent claims of the present invention are within the scope of protection of the present invention.
