Embodiment Construction

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0019] see Figure 1-4 , reflecting a preferred embodiment of the present invention, the fireworks paper tube includes a cylinder body composed of 7*7 array tubes 1, a base 2 arranged at the lower part of the cylinder body, and lead wires inserted on the base from the bottom 3. The diameter of the lead wire is 2-2.4 mm. The lead wire is inserted to form a lead post 31. One end of the single bobbin is open, and the other end is a bottom seal 11 with a glue layer, which is rotated and extruded by the bobbin itself Forming (firstly put the bottom end of the bobbin into the rubber basin to wet and soften, and then rotate and extrude through the rotary die), an adhesive layer is set between adjacent bobbins, and the bobbins are connected together through the adhesive layer to form ...

Abstract

The invention discloses a fireworks paper tube. The fireworks paper tube comprises a tube body consisting of multiple bobbins, a base arranged at the lower part of the tube body, and a lead inserted into the base from the bottom of the base; the lead is inserted to form a lead column; one end of single bobbin is opened, and the other end is a bottom seal with a glue layer; the bottom seal is formed by extruding the tube body; adhesive layers are arranged between the adjacent bobbins; the bobbins are connected through the adhesive layers to form the tube body; and a first through hole matched with the lead column is formed in the bottom of the tube body. The fireworks paper tube with the structure saves a mud bottom forming procedure, has no mud bottom to achieve cleanness and solve the fireworks transportation weight problem, can preferably prevent the problems of damping of the mud bottom of an inner tube and breakage of the bottom paper tube, and can preferably guarantee the product quality.

Description

technical field [0001] The invention relates to the structure of a firework paper tube, in particular to a firework paper tube structure without bottom mud. Background technique [0002] At present, both ends of the fireworks paper tubes on the market are open. When the firework paper tubes with both ends are open are used to produce fireworks effect tubes, the seal at one end is mainly sealed with yellow mud, and a hole for a lead wire is set in the middle of the yellow mud. The production process of the paper tube is complicated, it takes a lot of time, affects the production efficiency, and the labor cost is high; moreover, it requires a large amount of bottom sludge. If the bottom sludge is not pressed tightly during the production process of the bottom sludge, it will loosen and pollute the packaging and affect the discharge effect. Too tight can easily lead to problems such as paper tube rupture. [0003] Therefore, it is necessary to develop a firework paper tube wit...
