A cutting device for fireworks paper tube

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 positioning mechanism, and the positioning mechanism is used to cut the fireworks paper tube Positioned on the cutting mechanism, the cutting mechanism is used to cut the fireworks paper tube, and the driving mechanism is used to drive the cutting mechanism; when cutting, first start the drive 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, and then drives the cutting bracket to rotate, the cutting bracket drives the roller and the cutter assembly to press down, while the roller is tightening the fireworks paper tube, the cutter assembly is pressed against the fireworks paper. With the rotation of the half gear, it is disconnected from the driven gear, and the cutting bracket is reset under the elastic force of the torsion spring; this device can precisely position the fireworks paper tube, and has a simple structure, easy to use, and extremely Great labor savings.

Description

technical field [0001] The invention belongs to the technical field of fireworks production machinery, and in particular relates to a cutting device for fireworks paper tubes. 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...

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
