Paper tube sealing method

Abstract

The invention discloses a paper tube sealing method in firecrackers and firework production processes, and aims to solve the problems that loess, gypsum powder and the like are generally adopted for sealing before the firecrackers and the firework production processes are disclosed, and the gypsum powder sealing has the defects of long curing time, interruption of production procedures, incapability of realizing continuous automatic production, serious environmental pollution, high production cost, high transportation cost, high production efficiency and the like. In order to solve the sealing problem in firecracker and firework production, a method of rotationally extruding paper on the inner wall of a paper tube is adopted, so that the paper on the inner wall of the paper tube is tightly extruded towards the center of the paper tube to seal a paper tube opening, and the purpose of sealing the paper tube is achieved.

Description

Technical Field

[0001] The invention relates to a production process of firecrackers and fireworks, and is a sealing method in the production process of firecrackers and fireworks. Background Art

[0002] Prior to the present invention, firecrackers and fireworks were produced by sealing with loess, gypsum powder, etc. Generally, loess is used to seal the bottom of the firecracker tube, and gypsum powder is used to seal the lead end of the firecracker. The gypsum powder needs to absorb moisture in the air to solidify from powder to block. Therefore, it takes two to three days in the southern region with high air humidity. During these two or three days, the production process is interrupted during the production of firecrackers, and automated continuous production cannot be achieved. In addition, such methods also have the problems of great environmental pollution, high production costs and high transportation costs. In order to solve the sealing problem in the production of firecrackers and fireworks, the present invention adopts a method of rotating and squeezing wallpaper sheets in a paper tube, so that the wallpaper sheets in the paper tube are squeezed toward the center of the paper tube to form a closed paper tube mouth. Summary of the invention

[0003] Since the paper tubes used for firecrackers and fireworks are formed by the accumulation of paper circles, the sealing of the paper tube refers to the sealing of the two ends of the paper tube. The purpose of the present invention is to use the paper tube body to seal, without using other materials such as loess and lime. To achieve this purpose, the paper tube is fixed, the extrusion head is rotated and extruded downward, so that the rotating extrusion force squeezes the wallpaper sheets in the paper tube toward the center of the paper tube to form a closed paper tube mouth. It is characterized in that: a rotating extrusion force is applied to the end of the paper tube to squeeze the wallpaper sheets in the paper tube, so that the wallpaper sheets in the paper tube are squeezed toward the center of the paper tube to form a closed paper tube mouth to achieve the sealing purpose.

[0004] The gist of the invention is:

[0005] 1. The rotation speed and downward pressure of the rotating extrusion head should be appropriate.

[0006] 2. The extrusion stroke should be greater than the radius of the outer diameter of the paper tube.

[0007] 3. The outer diameter of the extrusion head is slightly smaller than the outer diameter of the paper tube.

[0008] The present invention has the advantages that:

[0009] 1. It solves the problem that the production process of firecrackers and fireworks is interrupted due to sealing and the automatic production cannot be realized.

[0010] 2. The paper tube body is used for sealing, which reduces the production cost.

[0011] 3. The absence of loess, gypsum powder, etc. reduces the environmental pollution caused by fireworks. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1It is a three-dimensional diagram of a paper tube sealing method, which is also an abstract illustration. In the figure, 1 is a paper tube, which is formed by the accumulation of paper circles, 2 is an extrusion head, 3 is the rotation direction of the extrusion head, and 4 is the extrusion direction. The working principle is: fix the paper tube 1, rotate the extrusion head, and then apply pressure downward so that the downward pressure of the rotating head squeezes the wallpaper in the paper tube toward the center of the paper tube to achieve the purpose of sealing the paper tube.

[0014] 1. The extrusion head grinds the 118-degree cutting angle of the twist drill into a 180-degree flat edge and grinds off the cutting edge.

[0015] 2. The paper tube should be clamped tightly and the concentricity of the rotating head should be good, otherwise the swing of the rotating head will damage the outer layer of the paper tube and affect the appearance of the paper tube.

[0016] 3. The diameter of the extrusion head is smaller than the outer diameter of the paper tube, generally smaller than the thickness of two to three pages of paper, ensuring that the paper tube is beautiful and complete after sealing.

[0017] Conclusion, this embodiment achieves the purpose of the invention.

Claims

1. A paper tube sealing method is a process in the production of firecrackers and fireworks. The present invention adopts a method of rotating a rotating head to rotate and squeeze the wallpaper sheets in the paper tube so that the wallpaper sheets in the paper tube are squeezed toward the center of the paper tube to form a closed paper tube mouth, characterized in that: A rotating extrusion force is applied to the end of the paper tube to squeeze the wallpaper sheets inside the paper tube, so that the wallpaper sheets inside the paper tube are squeezed tightly toward the center of the paper tube, forming a closed mouth of the paper tube to achieve the purpose of sealing.
