A firecracker paper tube cutting device

Abstract

The invention provides a cutting device for fireworks paper tubes with the following structure, which includes a frame and a driving mechanism arranged on the frame, a cutting mechanism and a pushing mechanism, and the driving mechanism is used to drive cutting mechanism, the cutting mechanism is used to cut the fireworks paper tube, and the pushing mechanism is used to push out the cut fireworks paper tube; when cutting, first start the driving motor to drive the fireworks paper tube to rotate, and at the same time the low-speed motor starts And drive the half gear to rotate, the half gear drives the driven gear to rotate, the cutting bracket overcomes the elastic force of the torsion spring and rotates with the driven gear, and then the cutting bracket drives the cutter assembly to press down and cut the fireworks paper tube; When the gear rotates, it is disconnected from the driven gear, the driving force on the driven gear disappears, and the cutting bracket resets under the elastic force of the torsion spring; finally, the pushing mechanism pushes out the cut fireworks paper tube on the rotating rod. The device is simple in structure and easy to use, which greatly saves labor.

Description

technical field [0001] The invention belongs to the technical field of fireworks production machinery, and in particular relates to a fireworks paper tube cutting device. Background technique [0002] Fireworks are pyrotechnic entertainment products that use pyrotechnic powder to produce sound, light, color and other effects through combustion or explosion for viewing, and are an important part of Chinese folk customs. At present, my country is the world's largest producer, exporter and consumer of fireworks, accounting for 90% of the world's total. The production process of the firecracker paper tube on the outer layer of the firecracker is relatively complicated. First, glue is used to supply the glue needed for rolling the paper tube, and then the paper is rolled into the firecracker paper tube by machinery. In order to speed up production and save labor, the fireworks paper tubes are usually rolled into a longer size, and then the fireworks paper tubes are cut into suit...

AI Technical Summary

Problems solved by technology

[0003] The existing cutting methods for firecracker paper tubes are divided into manual cutting and mechanical cutting. Manual cutting is time-consuming and labor-intensive, and the cutting accuracy is not enough, and there are many defective products.

Mechanical cutting has accurate precision, high efficiency, and saves time and effort, but the existing fireworks paper tube cutting device has a complex structure and high cost, which is not conducive to popularization

In addition, the blades on the fireworks paper tube cutting device are easy to wear and inconvenient to replace, which increases the maintenance cost
