Description

Automatic assembling system for combined fireworks

Technical Field

The invention relates to an automatic assembly line production system for assembling combined fireworks.

Background

The combined firework assembly production relates to the processes of propellant powder dispensing, propellant powder feeding and explosive charging, bottom paper sheet punching and filling, effect piece assembly, surface paper sheet punching and filling and the like. Wherein, the propellant powder charging is directly carried out by the producer against each combined firework emission hole. The traditional manual medicine charging has two problems which are difficult to be solved thoroughly: firstly, the explosive charging workers directly contact with the pyrotechnic composition, and once an accident occurs, the tragedy that the factory destroys the death of the people is often caused, and the consequence is unimaginable. The working conditions and environment, open fire, cable fire, fire source contact, friction, impact, static electricity and other factors can cause pyrotechnic compositions accidents; secondly, the production quality and the efficiency are low.

The assembly of the effect piece is the work of pointing to the combined firework launching hole (also called outer cylinder) and embedding the effect piece (also called inner cylinder), at present, the manual work is adopted, the inner cylinders are manually assembled into the launching hole one by one, and the defect of the assembly is that the assembly is carried out in the following ways: firstly, the inner cylinder is filled with inflammable and explosive effect pyrotechnic compositions, and a manual operation method is adopted, so that the life safety of operators is endangered once accidents occur; secondly, the manual operation easily causes the problems of neglected loading, wrong loading and the like of the inner cylinder, so that the quality of the combined fireworks is uneven and the preset setting-off effect cannot be achieved; thirdly, the production efficiency is extremely low; and fourthly, based on the combination characteristics of the combined fireworks, various inner cylinders with different effects can be arranged in each combined fireworks, for example, one row of launching holes are arranged in the inner cylinder A, and the other row of launching holes are arranged in the inner cylinder B. At present, no mechanical equipment capable of achieving the selective mixing loading exists.

The round paper pieces (commonly called paper bars in the industry) which are used for layered isolation are required to be arranged in the emission holes of the combined fireworks, the paper pieces are divided into bottom paper pieces and surface paper pieces, the center of each bottom paper piece is provided with a fire transfer hole, and each surface paper piece is not provided with a fire transfer hole. The traditional manufacturing process is that a machine is used for punching a yellow paper board into circular paper sheets with the shape corresponding to the inner cavity of the emission hole, workers place the paper sheets one by one and press the paper sheets into the emission hole by a wood stick, a flashlight is used for checking whether the paper sheets are flat one by one, and if the paper sheets are not flat, the paper sheets are taken out by a hook needle and pressed again. The manual filling process has the defects of large labor load, extremely low production efficiency and serious influence on the firework production progress.

The time of the safety accident of the fireworks and crackers is usually only three hundred thousandths of a second, and according to the current technical level, any technical means cannot immediately stop the bad results caused by the safety accident, so the technology for preventing the production safety accident is particularly outstanding. By adopting mechanical equipment in the production of fireworks and crackers, an automatic assembly line production system comprising main production processes of combined fireworks, particularly dangerous processes is established, so that accidents are prevented as much as possible; in case of accident, it can ensure no casualties. Is an extremely urgent and difficult task faced by the industry.

When unloading calandria 106 is in vertical state, location driving lever 131 descends and passes location upper hole 129 and insert transfer charging tray 2's locating hole 202, and its effect lies in:

one is as follows: when the positioning deflector rod 131 passes through the positioning upper hole 129 downwards, the wedge-shaped body 132 at the lower end of the positioning deflector rod is used as a guide to insert and deflect the deflector wheel 130, the deflector wheel 130 drives the door body 138 of the automatic door to move transversely through the connecting rod 137, after the door body 138 moves transversely in place, the arc-shaped part 135 of the positioning deflector rod is positioned at the gap 128, the arc-shaped part 135 is matched with the inner wall surface of the tube cavity, the inner tube of the firework cannot be prevented from falling, and the inner tube of the firework in the; after the positioning shift lever 131 moves upwards to reset, the door body 138 moves transversely reversely to reset, and the protrusion 127 of the door body extends out of the gap 128 (as shown in fig. 7) to prevent the firework outer barrel from falling.

Secondly, the transfer tray 2 of the pre-distribution station is accurately positioned, and the through hole 201 is aligned with the lower port 125 of the pipe cavity.

The inner cylinder filling device is provided with an infrared recognition system for detecting the in-place state of the transfer tray 2 and the combined fireworks 6.

By adopting the technical scheme, in the first inner cylinder pre-distribution mechanism 1 of the inner cylinder pre-distribution unit, the firework inner cylinder in the blanking hopper 101 falls into the inner cylinder distribution clamping groove due to the gravity and the shaking action, the push rod 114 pushes the firework inner cylinder at the bottom of the groove cavity into the tube cavity of the blanking exhaust pipe 106 in the horizontal state, the blanking exhaust pipe 106 is horizontally rotated to the vertical state, the automatic door is opened, and five firework inner cylinders enter one through hole line of the transfer plate 2. Then, the transfer tray 2 is conveyed to the next inner cylinder pre-distribution mechanism 1 by the first conveying mechanism 3, and the pre-assembly of the firework inner cylinder in the second through hole row is continued until the inner cylinder pre-distribution mechanism 1 of the whole inner cylinder pre-distribution unit finishes working. Each inner cylinder pre-distribution mechanism 1 can load firework inner cylinders with different effects. The transfer tray 2 filled with the firework inner barrel is conveyed to a filling station 503 of the inner barrel filling unit by the first conveying mechanism 3; meanwhile, the combined firework outer barrel conveying mechanism 7 drives the combined firework 6 to enter the filling station 503 from the lower part of the transfer tray 2; the lower pressing rod set is pressed downwards to press the firework inner barrel clamped in the through hole 201 of the transfer tray 2 into the emission hole of the combined firework 6. Thus completing the filling work of the inner firework cylinder of the combined firework 6. After the filling, the first conveying mechanism 3 drives the transfer tray 2 to leave. The operation is circulated in such a way. The combined firework outer barrel conveying mechanism 7 conveys the combined fireworks 6 which are filled with the propellant powder, the bottom paper sheets and the firework inner barrel to the surface paper sheet punching and filling subsystem.

The structure of the facial tissue filling subsystem is similar to that of the bottom tissue punching filling subsystem. Except that the tissue sheets need not be pressed with pinholes. The knife base plate can be provided with no needle assembly, and the tissue base plate can be provided with no corresponding needle through hole. The knife base plate is pressed downwards, the surface paper tube type cutter head punches circular paper sheets, then the surface paper punch stem base plate is pressed downwards, and the surface paper punch stem presses the circular paper sheets into the emission holes of the combined fireworks. The rest of the system is the same as the bottom paper sheet punching filling subsystem, and the description is omitted.

And finishing the combined fireworks filled with the surface paper sheets, namely the working finished product of the system.
