Embodiment 1

[0025] Embodiment 1: see Figure 1-7 , reflecting a specific structure of the present invention, the crimping and bottom sealing device of the combined fireworks outer cylinder includes a turntable 3 driven by a motor 303, a transmission 302, and a rotating shaft 301 to rotate intermittently, and eight positioning positions are evenly distributed along the circumference of the turntable 3. mechanism. Adapt to the working characteristics of the positioning cavity turntable system to achieve both efficiency and operational stability and reduce noise. Each positioning mechanism includes two cylinder positioning cylinder cavities 7 loaded with fireworks outer cylinders 100 arranged side by side. The feeding port 101 of the feeding hopper 1 is provided with a distribution member 102 . It is beneficial to improve the processing rate and the operation coordination of the positioning cavity turntable system.

[0026] During the rotation of the positioning mechanism with the turntab...

Embodiment 2

[0034] Example 2: see Figure 8 , the difference from Embodiment 1 is that the cylinder positioning cavities evenly distributed along the circumference of the turntable 404 adopt positioning grooves 410 .

[0035] It is no longer necessary to install a pusher at the blanking station 403, the notch of the positioning groove 410 corresponds to the discharge port of the discharge hopper 401, and the fireworks outer cylinder 402 at the discharge port corresponds directly to the radial direction of the cylinder according to gravity. Falling into the positioning groove cavity 410. A material roller 408 may be provided at the discharge opening of the discharge hopper 401 to help the fireworks outer cylinder 402 fall smoothly into the groove.

[0036] At the overlapping station 407 for crimping and pre-installation of paper bars, and the reinstallation station 406 for paper bars, a notch cover plate 405 is provided corresponding to the positioning groove cavity 410 to prevent the fire...

Embodiment 3

[0040] Embodiment 3: see Figure 9 , The barrel positioning cavity adopts a positioning groove cavity. The difference from Embodiment 2 is that the turntable adopts a fence structure, and the gaps between the railings form positioning grooves. For example, the gap 80e between the railing 90c and the railing 90b constitutes a positioning groove; or, the gap 80f between the railing 90a and the railing 90b constitutes a positioning groove. Firework paper tubes are clamped in the gaps 80e, 80f, etc.

Abstract

The invention discloses an edge curling and bottom sealing device of a combined firework outer cylinder. The device comprises a turntable intermittently rotated; multiple positioning mechanisms are distributed at the periphery of the turntable; the positioning mechanisms comprise cylinder body positioning cavities of the firework outer cylinder, and pass through an unloading station, an edge curling station and a paperboard punching station fixedly arranged on a frame in the process of rotating along with the turntable; the edge curling station comprises rotary pressure applying molds arranged corresponding to ports of the cylinder body positioning cavities; and the paperboard punching station comprises paperboard cutting mechanisms and paperboard punching mechanisms arranged corresponding to the ports of the cylinder body positioning cavities. As a multi-station and multi-angle working platform formed by combining the positioning cylinders with the turntable is built, the device realizes organic fusion of two procedures of edge curling and paperboard punching, prevents reduction of the mechanism redundancy and the efficiency caused by multiple times of positioned conveying of cylinders, and realizes efficient and reliable edge curling and bottom sealing on the basis of guaranteeing the quality.

Description

technical field [0001] The invention relates to a device for curling the bottom port of a fireworks outer tube and paper backing. Background technique [0002] Combination fireworks are fireworks products composed of multiple single tubes. A single tube is exactly a firework paper tube, because the inner tube filled with the effect medicine is often loaded into the single tube, the industry also calls the single tube an outer tube or a fireworks outer tube. Both ports of the fireworks outer tube made of paper are open. In the traditional craft, the bottom port of the outer cylinder of fireworks is sealed by a pressurized mud layer (commonly known as mud head or mud bottom). In order to avoid the disadvantages such as difficult mud layer construction, limited structural strength, and unfavorable recycling, there is now a new type of fireworks outer cylinder that curls the bottom port of the cylinder body: use a corresponding mold (such as the "firework firework" disclosed i...
