Technical Field

The invention relates to a combined firework. In particular to a product formed by combining similar or dissimilar products such as ground fireworks display, spraying decoration, spitting bead and the like.

Background

The combined fireworks are usually formed by connecting a plurality of paper tubes into a single-row paper tube (called a tube row for short); then, completing a punching and lead inserting process on the tube row, namely processing fire transfer holes on each paper tube by using punching needles, and inserting leads into the fire transfer holes to enable the paper tubes to be connected in series through the leads to form a fire transfer relation; the tube rows are laminated and assembled to form a shape (also called as a group basin), the shape of the group basin is a rectangular body as shown in figure 1, and the paper tube cavity device emits the medicine and the effect element which are ignited by the lead wires.

The traditional manual pot assembling process has the advantages of low working efficiency, high labor intensity, large amount of labor and high production cost. For this reason, automatic pot assembling equipment has been developed in the industry, and mechanized production equipment for combined fireworks is generally referred to as "pot assembling machine" or "firework assembling machine". Related patent documents in the prior art are 'a firework numerical control assembling machine' disclosed in CN 202158808U; the 'punching and inserting system for firework assembly' disclosed in CN 102213569A; CN102538597B discloses a firework assembling machine; CN106275650B discloses a foam strip imbedding device and an automatic firework assembling machine; the "method and system for assembling fireworks cartridge" disclosed in CN103307932B, etc. has been developed for many years, and the pot assembling device is now a well-established firework machine which is used in a large scale. However, various devices exist in which the blanking of the rows is the same as or similar to that disclosed in the above-exemplified patent documents. Since the number of related patent documents is large and is not listed.

The molded body processed by the existing equipment is shown in fig. 1, each paper tube row is a non-interval paper tube row with the paper tube bodies in close contact, the paper tube bodies forming the paper tube rows can only be closely arranged, and the interval between two paper tubes cannot exist. However, the wall thickness of the rolled paper tube is different; the lap part of the rolled cylinder body is raised, so that the cylinder body is not in a perfect circle shape; therefore, the radial size of the cylinder inevitably has errors with the standard size of the cylinder; the non-spacing cylinder row has no spacing among the cylinders, and the positions of the cylinders are not adjusted spatially, so that errors are accumulated in the cylinder row, and the actual positions of some cylinders have larger deviation with the stations of the equipment, which are preset according to the standard sizes of the cylinders; because the paper tube can not accurately reach the preset station, the accuracy and the reliability of the subsequent processes of punching, inserting and guiding, pressing in the paper-jaw (round paper board) and the like are reduced.

However, in the process of manufacturing the tube row of such a plurality of existing pot assembling machines, before the tube row is glued and fixed, the following operations must be performed by means of the close contact interaction of the tube bodies: firstly, the arrangement of the cylinder rows is kept not to be disordered; and secondly, the cylinder row is pushed to move to complete the streamlined production. Therefore, the conventional pot combining machine cannot process the tube rows with the intervals among the paper tubes (the tube rows with the intervals are called in the invention).

In the present invention, the cartridge before setting comprises the following states: no fixed cylinder rows such as adhesive tapes, double-sided adhesive tapes and the like are used; or the row of cartridges is not glue applied; or the row of cartridges has glue applied but the glue has not cured, etc.

In addition, the above apparatus cannot process the combined fireworks of the sector body.

However, according to the U.S. standard, paper tubes for combined firework products with a charge of 200-500 g must have a spacing of more than half an inch; the sector products have strong ornamental value, but the manual production is slow, a large number of orders can not be completed on time every year, and factories can only receive orders according to the production capacity.

The CN 103528446A discloses an automatic row device for combined fireworks, which can meet the requirement of a row of cylinders with intervals, and can also process combined fireworks of sector bodies. However, the efficiency of the blanking and the tube arranging is low, and the tube row conveying needs to be matched with a special transfer device, such as the transfer device of a combined firework tube row disclosed in CN104913691A, the production efficiency of the transfer device cannot meet the requirement of large-scale production; meanwhile, the problem that the cylinder row is easy to disorder before entering the transfer device and after exiting the transfer device is not solved.

Therefore, in actual production, when a combined firework product formed by the spaced tube rows needs to be processed, only a traditional manual mode can be adopted, and as shown in fig. 2, a manual production flow of a rectangular (paper tube vertical type) combined firework is shown; fig. 3 shows a manual production process of the fan-shaped combined fireworks. Firstly, manually brushing glue on the bottom paper board 2, and manually placing the paper tubes 1 one by one until the paper tubes are fully placed. Because the cylindrical paper tube bodies are easy to roll, particularly after the paper tube bodies are arranged into the tube rows with intervals, the paper tube bodies are not in contact with each other and lack of interaction, and the paper tube bodies are easy to change positions in the moving process before glue is not solidified; therefore, the paper tube 1 must be placed on a workbench to wait for the glue to be cured until the paper tube 1 cannot be displaced, about two hours in summer and about four hours in winter, and generally, the paper tube is placed in the morning and then inserted and laminated in the afternoon. The pots are then assembled, as shown in the rectangular body of FIG. 2, and the fan-shaped body of FIG. 3. For the products, the problems of low working efficiency, high labor intensity, large amount of labor and high production cost are not solved; meanwhile, because of manual operation, the position of each barrel body can have deviation to influence the setting off effect, particularly the sector body shown in figure 3, and after the sector body is launched to the high altitude, the deviation is amplified to seriously influence the setting off effect.

Disclosure of Invention

In order to solve the above drawbacks, the present invention provides a combined firework, which can maintain a stable structure of a spaced row of cylinders before the cylinder row is glued and fixed, and is convenient for realizing automatic production.

Preferably, the method further comprises applying glue to the paper tube and/or the base board. The glue application may be performed during the transport of the paper tube and/or the base board.

The two sides of the bottom paperboard are correspondingly provided with notch positioning holes, and the distance between the notch positioning holes positioned on the same side of the bottom paperboard is called as the hole spacing of the notch positioning holes. Preferably, the hole pitches of the notch positioning holes corresponding to the two sides of the bottom paperboard are the same. The vertical tube row of the rectangular combined fireworks is manufactured. Preferably, the hole pitches of the notch positioning holes corresponding to the two sides of the bottom paper board are different, and the hole pitch of the notch positioning holes close to the top end (emission end) of the paper tube is larger. The manufactured sector cylinder row of the sector combined fireworks.

In the fan-shaped section of thick bamboo row, in order to make the distribution of the breach locating hole that the bottom paperboard both sides correspond more coincide with the fan-shaped distribution position of barrel for the barrel both ends block in two corresponding breach locating holes just, can not stubborn the other cardboard of hole of turning round, thereby effectively improve the structural strength who fixes a position. Preferably, the bottom paper board is composed of a middle straight section and two side inclined sections.
