Abstract
The utility model discloses an improved structure of a compression molding composite firework. A plurality of tubular cavity bodies are evenly distributed on a composite firework body in parallel. Upper end openings of the tubular cavity bodies are opened, and lower end openings of the tubular cavity bodies are closed and provided with fire transmitting holes. Firework launching powder and effect components are arranged in the tubular cavity bodies, and the upper end openings of the tubular cavity bodies are big-end-down taper-shaped end openings. When round paper enters into the tubular cavity bodies, the big-end-down taper-shaped end openings act to guide so that the round paper can be naturally transited to be in a concentric state with the tubular cavity bodies along the inner walls of the taper-shaped end openings in a descending process. Thus, when the round paper is pressed to go deep into the tubular cavity bodies, the round paper can be kept horizontal, and the problems of rollover and the like do not exist. The improved structure of the compression molding composite firework has the advantages of being simple in scheme, clever, easy to operate and low in cost.
Description
Technical field
The utility model relates to a kind of amusement pyrotechnics product, especially a kind of combined firework.
Background technology
According to the definition of State Standard of the People's Republic of China GB10631-2004 " fireworks and crackers safety and quality " and GB19593-2004 standardization files such as " fireworks and firecrackers combined fireworks ", combined firework is the firework product that is combined by a plurality of monotubulars.A monotubular is called one.The conventional combination fireworks are assembled by a plurality of paper bobbins, have that operation is various, production efficiency is low, not high an etc. drawback of the standardization of product or standard.
My company has developed a kind of combined firework of overall time moulding in recent years, with slurry by compression molding.The shape of its formed body and structure and conventional combination fireworks are similar, and the overall appearance shape of the body of formed body is generally rounded edges cylinder or cylinder etc.The some tubular housings of parallel even distribution on the body, the monotubular of the structure of tubular housing and effect and conventional combination fireworks is similar, and the tubular housing upper port is open, and the lower port sealing also arranges flash hole, the built-in launching fireworks medicine of tubular housing and effect part.
Mainly adopt home built technology different with tradition, the combined firework of this overall time compression molding is to adopt the production of mechanized equipment streamline, but following problems appearring easily in this large-scale production process: (is commonly called as paper bar bar at the circular paper of packing into simultaneously to a plurality of circular cylindrical cavities, its effect is that launching fireworks medicine and the effect part that tubular housing is built-in carries out the layering isolation) time, the part circular scraps of paper are prone to phenomenons such as rollover in the tubular housing content, need hand inspection correction one by one; Caused production efficient to reduce, production cost increases.Simultaneously, also there are problems such as technical difficulty is big, equipment manufacturing cost is high in the generation of stopping the problems referred to above by improved production equipment.Especially it should be noted that these problems may occur in any one monotubular (1 or a tubular housing), and the product of a streamline every workday production is easily with tens thousand of calculating, so the control production cost also is the problem that must consider.
Summary of the invention
In order to solve above-mentioned drawback, technical problem to be solved in the utility model is, a kind of structural improvement of combined firework of overall time compression molding is provided, and can guarantee the quality of packing into of circular paper at lower cost.In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of structure-improved of compression molding combined firework, the some tubular housings of parallel even distribution on the described combined firework body, the tubular housing upper port is open, and the lower port sealing also arranges flash hole, the built-in launching fireworks medicine of tubular housing and effect part, it is characterized in that described tubular housing upper port is up big and down small taper port.
The beneficial effects of the utility model are, when circular paper enters tubular housing, up big and down small taper port has played guide effect, make circular paper in descending process, carry out the transition to naturally and the body concentric state of tubular cavity along the taper port inner wall, so can keep level in the time of in pressurized gos deep into tubular housing, problems such as rollover can not occur.Adopt technique scheme to have simple, the ingenious easy row of scheme, advantage with low cost.
In order to finish described guide effect better, and take into account the launching effect that guarantees tubular housing.Preferably, the height of described taper port is 3-30mm, and the diameter difference is between 0.2-6mm between the bottom surface circle that described taper port is bigger and the less bottom surface circle.
With improvement, the tubular housing that is connected with described taper port bottom surface is up big and down small cone-shaped cavity.In the process of circular paper in pressurized gos deep into tubular housing, the cavity inner wall of inclination gives circular paper circumference stable and that increase gradually and supports, and stops the possibility of circular paper rollover fully; And when cancelling, downforce accurately rests on the precalculated position; Cavity inner wall fully contacts with the circular paper periphery, fully realizes the layering buffer action.
Further preferably, cross-sectional diameter and the circular paper equal diameters of the neck of described taper port bottom surface (being described less bottom surface circle) and cone-shaped cavity joining place.The effect of this neck is to establish the location datum level of a circular paper, guarantees that circle scraps of paper level is descending.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is the utility model specific embodiment whole interior structural profile schematic diagram;
Fig. 2 is A shown in Figure 1 portion structure for amplifying schematic diagram.
The specific embodiment
Referring to accompanying drawing, reflect a kind of concrete structure-improved of the present utility model, the some tubular housings 1 of parallel even distribution on the described combined firework body, the upper port 2 of tubular housing 1 is open, lower port 3 sealings also arrange flash hole 4, tubular housing 1 built-in launching fireworks medicine and effect part, the upper port 2 of described tubular housing 1 is up big and down small taper port, highly be 3-30mm, the diameter difference is between 0.2-6mm between the bottom surface circle 7 that described taper port is bigger and the less bottom surface circle, and bottom surface circle less in this example overlaps with neck 5.The tubular housing that is connected with described taper port bottom surface (being neck 5 places) is up big and down small cone-shaped cavity 6.The cross-sectional diameter of described neck 5 and circular paper equal diameters.
The above-mentioned embodiment that the utility model is described only is for the technical solution of the utility model clearly is described, and can not be interpreted as the utility model is made any restriction.The utlity model has known multiple alternative and distortion, under the prerequisite that does not break away from the utility model essential meaning, all fall into protection domain of the present utility model.
