Tube coiling machine for quick-dry firework paper tube

Abstract

The invention discloses a tube coiling machine for a quick-dry firework paper tube. A softening mechanism is arranged between a raw paper coil and a gluing mechanism. The softening mechanism comprises two paper positioning parts which are arranged in a front-back manner in the paper feeding direction. A softening part is arranged between the two paper positioning parts. The softening mechanism further comprises a paper relieving part between the raw paper coil and a paper V-shaped folding part. The softening mechanism positions paper for V-shaped folding, and the paper redundancy is preset for compensating for dragging of the paper during state switching of the softening part. The tube coiling machine can complete softening treatment on sealing paper on the outer ring of the firework paper tube in the tube coiling working process, the sealing effect can be ensured without wetting the paper through water dipping, and the paper tube can be prevented from being baked and basked and is rapidly dried; meanwhile, the phenomenon of paper snapping is avoided, and running is reliable and stable; the tube coiling machine is particularly suitable for work of tube coiling borers with paper inserting gaps; and the production efficiency can be effectively improved, and the quality of finished paper tube products is better improved.

Description

Technical field [0001] The invention relates to a rolling device for a firework paper tube. Background technique [0002] The firework paper tube (tube) is an important part in the production of fireworks. The firework paper tube is generally rolled by a fully automatic machine. [0003] Patent document CN203666021U discloses "a small-diameter firework tube automatic rolling machine", which is used to moisten the edges of the paper to facilitate the roll by setting a water pump. This process of using sticky wet paper softens the paper at the outer ring seal of the cylinder to ensure the sealing effect. However, the produced paper tube has a high water content, which must be dried or sun-dried afterwards, which is time-consuming and labor-intensive. In addition, the water content at the seal of the cylinder is higher than other parts of the cylinder. During the process of the cylinder from wet to dry, the shrinkage of each part of the cylinder is different, which causes the cylind...

AI Technical Summary

Problems solved by technology

[0005] 1. During the operation of the equipment, when the extrusion part squeezes and shapes the paper downward, the paper must be in a straightened state. The paper is very easy to break under the simultaneous action of tension and extrusion force, and the machine needs to be stopped for cleaning. paper, and then re-load the paper and start the machine, the stability and practicability are not high;

[0006] 2. The equipment does not have a good softening effect on the paper, and the outer ring seal of the paper tube is still prone to degumming and cracking;

There is no paper insertion gap on the reel brazing, and the winding of the reel brazing depends on vacuum adsorption, which not only complicates the mechanism, but also makes the paper softening effect difficult to meet the reel requirements of the reel equipment using the paper insertion gap reel brazing
