[0038] The technical solution of the present disclosure will be described below by taking the firework outer tube 300 and the frame laminating and film pressing device for laminating the upper and lower packaging films of the firework outer tube 300 as an example.

[0039] According to an example of the present disclosure, by the assembly diagram Figure 2-Figure 7 As can be seen from the upper frame pasting structure, the upper frame pasting film pressing device can include an upper film pressing seat 100, which is roughly consistent with the upper end surface shape of the firework outer tube 300 and is used to press and seal during the film pasting process. Figure 1 The upper film 400 is shown.

[0040] Furthermore, an upper floating plate 101 is connected to the upper end of the upper film pressing seat 100, and the upper floating plate 101 is provided with a plurality of lugs toward the front, rear, left and right sides of the firework outer tube, and each lug is provided with a hole for accommodating the upper film pressing shaft 102 to pass through, so that both ends of the upper film pressing shaft 102 pass through the hole to form a connecting portion for connecting an upper frame pasting assembly 103, and the upper frame pasting assembly 103 includes an upper frame pasting rack 1030 composed of three profiles and an upper roller 1031 installed on the upper frame pasting rack 1030, wherein the connecting portions on both sides of the upper film pressing shaft 102 are connected to the middle of the two profiles, so that the upper frame pasting rack 1030 is movably hinged to the upper film pressing shaft 102, and the number of the upper frame pasting assembly 103 is four groups, corresponding to the four sides of the firework outer tube 300 respectively, and during use, it can rotate around the upper film pressing shaft 102 to be unfolded before or after pressing.

[0041] like Figure 3 As shown, a first driving module 107 is provided on the upper surface of the upper floating plate 101. In the present embodiment, the first driving module 107 and the following driving modules can all be driving cylinders. The upper support plate 105 is connected to the output end of the first driving module 107. When the number of upper frame sticker components 103 is four, the upper support plate 105 extends toward the corresponding four end faces, and an upper connecting rod 106 is hinged at the extended end. An upper pivot member 104 is pivoted on the other side of the upper connecting rod 106. The other side of the upper pivot member 104 is fixedly connected to the third profile of the upper frame sticker frame 1030, and the connecting portion is away from one side of the upper roller 1031.

[0042] In the specific working process of the above embodiment, first, the upper film pressing seat 100 is used to press the upper film 400 onto the upper end surface of the firework outer tube 300, and then, the first driving module 107 is started, and the upper support plate 105 is pushed or pulled by the output end, and the four upper frame pasting components 103 are rotated around the above-mentioned upper film pressing shaft 102 through a multi-hinged connecting rod mechanism, and the four upper frame pasting components 103 are unfolded, and finally, the upper support plate 105 is pressed down to make the upper floating plate 101 descend. During the descending process, the four groups of upper film pressing shafts 102 drive the four upper frame pasting components 103 to descend, and then the upper rollers 1031 are folded to press the four sides of the upper film 400, so that it is tightly attached to the four sides of the firework outer tube 300 to complete the frame pasting and film pressing.

[0043] In order to guide the upper floating plate 101 to close or separate relative to the upper film pressing seat 100, the upper film pressing seat 100 is provided with a guide rod 108, which passes through the upper floating plate 101, and a buffer spring 109 is provided on the outer sleeve of the guide rod 108 between the upper film pressing seat 100 and the upper floating plate 101. After the external force is removed, the upper floating plate 101 can be reset by the buffer spring 109.

[0044] In the public examples, such as Figure 7 As shown, a sliding shaft 114 is fixed to the upper surface of the upper floating plate 101, a top fixing plate 115 is arranged at the upper end of the upper support plate 105, the sliding shaft 114 passes through the top fixing plate 115 and is slidably connected to the top fixing plate 115, a floating joint 116 is arranged between the top fixing plate 115 and the upper support plate 105, the floating joint 116 is connected to the upper floating plate 101 through a guide column 117, a third driving module 118 is installed on the top fixing plate 115, the output end of the third driving module 118 is used to resist the floating joint 116, and the third driving module 118 provides a downward thrust to the upper floating plate 101 and the upper frame assembly 103.

[0045] Preferably, a damping member 119 is provided between the upper support plate 105 and the floating joint 116 to absorb the impact force and reduce the vibration caused by the impact.

[0046] Please refer to Figure 4 , Figure 5 A tension spring fixing part 110 is arranged on the upper floating plate 101 toward the upper film pressing seat 100, and a hanging hole for hooking a tension spring 111 is arranged on the tension spring fixing part 110 toward the upper frame holder 1030, and a tension spring 111 is hooked on the hanging hole, and another hanging mouth of the tension spring 111 is connected to the upper frame holder 1030. When the upper roller 1031 rotates outward around the upper film pressing shaft 102 as the axis, the tension spring 111 has an elastic force to rotate the upper roller 1031 inward, that is, the pressure during film pressing is provided by the tension of the tension spring 111 on the upper frame holder 1030. The tension spring 111 is used to realize adaptive force adjustment in the film pressing process, so as to avoid excessive or insufficient pressure affecting the quality of the outer tube of the fireworks.

[0047] like Figure 6 As shown, the upper film pressing seat 100 is provided with a through receiving hole 1001, and a mounting seat 120 is installed on the upper surface of the upper film pressing seat 100. A second driving module 112 is arranged on the mounting seat 120. The output end of the second driving module 112 is connected to a suction cup seat 113. The suction cup seat 113 is located at the upper end of the upper film pressing seat 100 and forms a floating space for accommodating the suction cup seat 113 with the upper film pressing seat 100. The bottom of the suction cup seat 113 is provided with a vacuum suction cup 120 corresponding to the receiving hole 1001. 1. When the second driving module 112 drives the suction cup seat 113 to float, the vacuum suction cup 121 can be extended into or stored in the storage hole 1001. It can be understood that during use, the vacuum suction cup 121 can be extended into the storage hole 1001 to suck the upper film 400, and the upper film 400 can be placed in the frame position. During the film pressing process, the vacuum suction cup 121 can be hidden and retracted into the storage hole 1001, and the upper film 400 is fixed by the lower end surface of the upper film pressing seat 100.
