Description

Fireworks matrix

Technical field

A kind of firework device is the utility model is related to, particularly a kind of fireworks matrix.

Background technology

In fireworks production, one end of paper tube must be closed, and conventional processes are commonly called as " beating mud head ", i.e., be compacted in paper tube one end Soil, form the mud layer of closure isolation.This way needs a large amount of soil, welding, and soil is dirty after firework display Contaminate environment." beating mud head " labor intensity is big by hand, and working environment is poor, low production efficiency.And mechanical " mud pressing head ", floor space Greatly, it is complicated, poor reliability.Recently substitute mud head with the circle scraps of paper, i.e., go out the round scraps of paper first, then it is pressed into paper tube. This method, manual operation waste time and energy, again very high with machine cost, and the circle scraps of paper and paper tube inwall bad sealing, influence Product quality.

Each paper tube must be punched first in addition, then inserted and drawn, must also be inserted per ADF pipe draw it is connected.If manual operation, take When it is laborious, yield poorly, quality is difficult to ensure.If using machinery, equipment acquisition cost is high, floor space is big, operation troubles is more.

The content of the invention

For overcome the deficiencies in the prior art, the utility model provide it is a kind of it is simple in construction, cost is cheap, safe and reliable Fireworks matrix.

The utility model adopts the following technical scheme that.

A kind of fireworks matrix, has string to draw base and cylinder cake, and cylinder cake insertion string draws in base.

It is one block of plate that the string, which draws base, there is round pit above plate, and the inner peripheral surface of circle pit is inner cylinder face, circle pit Center have a boss, have one and the hole communicated below plate above boss, there is groove below plate, the groove below plate Communicated with the hole of all boss；

The cylinder cake is made up of single bobbin, and single bobbin has a body and ttom of pipe, and there is an open-work at the center of ttom of pipe, one Bobbin insertion string draws in a round pit of base.

The string draws the groove of base and communicated with a side of plate or two sides.

The bottom surface for going here and there the circle pit for drawing base is plane or is to curved surface convex below plate or is to above plate Convex curved surface.

It is rotation arc surface that the string, which draws the inner cylinder face of the circle pit of base with the intersection of the bottom surface of circle pit,.

The boss top that the string draws base is round platform, and bottom is cylinder, and one of sulculus is arranged at boss top.

The single bobbin of the cylinder cake is single paper tube, and single paper tube has body and ttom of pipe, and the ttom of pipe is folded by paper, phase Mutually overlap joint forms, and has bonding agent between the folding of paper, mutual overlap, neighboring and the body of ttom of pipe are integral, ttom of pipe All foldings, after the paper spread apart that mutually overlaps, turn into the extension of body, there is an open-work at the center of ttom of pipe.

The ttom of pipe of the single bobbin of the cylinder cake is flat convex or convex inwards.

The ttom of pipe of the single bobbin of the cylinder cake is rotation arc surface with body intersection.

Compared with prior art, the utility model has the advantage of simple in construction, reliability is high, simplifies process, reduces Cost, improve the quality and quantity of product.

Brief description of the drawings

Fig. 1 is the structural representation of the utility model embodiment.

Fig. 2 is the structure schematic top plan view that string draws base.

The structure bottom that Fig. 3 draws base for string regards schematic diagram.

Embodiment

The utility model is described in further detail below in conjunction with drawings and examples.

As shown in Fig. 1-3, a kind of fireworks matrix has string to draw base 6 and cylinder 15, and cylinder 15 inserts string and drawn in base 6. The string, which draws above base 69, round pit 4, and the inner peripheral surface of circle pit 4 be inner cylinder face 8, and inner cylinder face 8 is with justifying pit 4 The intersection of bottom surface 12 is rotation arc surface 11, and there is a boss at the center of circle pit 4, and boss top is round platform 1, round platform 1 There is one to draw 10 hole 2 communicated below base 6 with string above, there be one of sulculus 3 on boss top.Boss bottom is cylinder 5. String, which draws, a groove 7 below base 6, groove 7 communicates with the hole 2 of all boss.The right flank 13 that groove 7 draws base 6 with string communicates. The cylinder 15 is made up of single paper tube 14, and in the insertion circle pit 4 of paper tube 14, single paper tube 14 has body 16 and ttom of pipe 17, institute State ttom of pipe 17 folded by paper, mutually overlap joint form, have bonding agent, the periphery of ttom of pipe 17 between the folding of paper, mutual overlap Side and body 16 are integral.After all foldings of ttom of pipe 17, the paper spread apart mutually overlapped, turn into the extension of body 16 Point.Ttom of pipe 17 is flat, and ttom of pipe 17 has an open-work 3, and ttom of pipe 17 is rotation arc surface with the intersection of body 16.

In the present embodiment, circle pit 4 or the longitudinal quantity often arranged of single paper tube 14 are 4, and circle pit 4 or single paper tube 14 are horizontal Also it is 4 to the quantity of every row.Typically, it is the Arbitrary Digit in 2 to 30 to justify the quantity that pit or single paper tube are longitudinally often arranged, and justifies pit Or the quantity laterally often arranged of single paper tube is the Arbitrary Digit in 2 to 30.
