Description

Technical Field

[0001] The utility model belongs to the technical field of fireworks production and manufacturing, in particular to a fireworks inner tube filling structure and fireworks inner tube filling equipment. Background Art

[0002] In the current assembly process of molded fireworks, the work of inserting effect parts (also called inner tubes) into the launch holes (also called outer tubes) of combined fireworks is still done manually. The inner tubes are manually assembled into the launch holes one by one, which has the following disadvantages: first, the inner tubes are filled with flammable and explosive effect pyrotechnic powder. If an accident occurs during manual operation, the life safety of the operators will be endangered; second, manual operation is prone to problems such as missing or wrong installation of the inner tubes, resulting in uneven quality of the combined fireworks and failure to achieve the preset firing effect; third, the production efficiency is extremely low.

[0003] In order to solve the above problems, the inventor applied for a combined automatic filling device for fireworks inner tubes (application number: CN202321458145.7). The utility model includes a workbench and a filling device. The filling device includes a frame and a feeding mechanism, a material dividing mechanism, a material pushing mechanism and a loading mechanism installed on the frame. The feeding mechanism includes a feeding hopper and a swinging mechanism. The fireworks inner tubes are stacked in the feeding hopper; the material dividing mechanism includes a material dividing plate vertically arranged below the feeding hopper, and a plurality of material dividing guide grooves are arranged on the material dividing plate; the material pushing mechanism includes a pushing cylinder and a pushing plate, and the pushing plate is located below the material dividing guide groove; the loading mechanism includes a blanking plate and a hanging device, and a blanking groove is arranged on the blanking plate. The hanging device includes a hanging plate and a lifting cylinder located at both ends of the hanging plate, and a hanging block is arranged on the hanging device. Through the feeding mechanism, the material dividing mechanism, the material pushing mechanism and the loading mechanism, the automatic filling of the fireworks inner tube is completed, the production efficiency is improved, the safety hazards are reduced, and manpower and material resources are saved.

[0004] When the equipment is in use, since the inner tube of the fireworks falls directly along the drop chute into the outer tube of the fireworks located on the workbench, the inner tube of the fireworks may be affected by the vibration generated by the operation of the machine when falling, causing it to move in the horizontal direction, making it difficult to control the falling path of the inner tube of the fireworks. Often, the inner tube of the fireworks cannot fall accurately into the outer tube of the fireworks, and the inner tube of the fireworks that falls outside the outer tube of the fireworks needs to be manually reloaded. Utility Model Content

[0005] In view of this, the purpose of the utility model is to overcome the deficiencies in the prior art and provide a firework inner tube filling structure. The present application provides the following technical solutions:

[0006] It includes a placing platform and a material receiving plate. The material receiving plate is installed on a material receiving slide rail frame above the placing platform. A material receiving through hole is arranged on the material receiving plate. The upper end of the material receiving through hole is bucket-shaped and the lower end is column-shaped. A discharge plate is slidably arranged at the bottom of the material receiving plate. The discharge plate is provided with a discharge hole corresponding to the material receiving through hole.

[0007] The material receiving plate is also provided with a discharge cylinder, the telescopic end of which is connected to the discharge plate, and the discharge cylinder is used for driving the discharge plate to slide relative to the material receiving plate.

[0008] The material receiving slide frame includes a support frame, on which a material receiving slide and a transmission belt group are arranged, a mounting plate is arranged on the material receiving slide, the mounting plate can slide along the material receiving slide, the material receiving plate is bolted to the mounting plate, one end of the mounting plate is fixed to the transmission belt group, the transmission belt group is connected to a driving motor, and the driving motor drives the transmission belt group to move.

[0009] The placement platform is provided with a fireworks outer tube positioning structure, and the placement platform is slidably mounted on a platform guide rail provided below the placement platform.

[0010] The fireworks outer tube positioning structure includes an abutment bar fixed on the placement platform and a guide bar and a limit bar located outside the placement platform. The abutment bar is L-shaped, and an inclined guide portion is provided at the front end of the guide bar. The guide bar is located on the side of the placement platform, and the limit bar is located at the end direction of the platform guide rail.

[0011] By providing abutment strips, guide strips and limit strips, when the outer tube of the fireworks is placed on the placing platform, as the placing platform slides on the platform guide rail, the side of the outer tube of the fireworks contacts the guide strip, and the guide strip squeezes and pushes the outer tube of the fireworks close to the abutment strip. After the placing platform slides into place, the outer tube of the fireworks contacts the limit strip. At this time, the abutment strips, guide strips and limit strips contact the four sides of the outer tube of the fireworks to position and clamp the outer tube of the fireworks.

[0012] A limiter and an induction switch are provided at the end of the platform guide rail, wherein the limiter is used for limiting the sliding of the placement platform on the platform guide rail, and the induction switch is used for sensing the position of the placement platform, and the induction switch is electrically connected to the unloading cylinder.

[0013] The placement platform is provided with a plurality of mounting holes for bolt mounting the pad.

[0014] By adding a pad, the outer tube of the fireworks is raised so that the tube mouth of the outer tube of the fireworks is close to the bottom of the receiving plate, so that the inner tube of the fireworks can fall directly from the receiving plate into the outer tube of the fireworks. In addition, pads of different heights can be arranged to adapt to the height of the outer tube of fireworks of different models.

[0015] On the second aspect, the present application also provides a firework inner tube filling device, including the above-mentioned firework inner tube filling structure, and also including a body and a feeding mechanism, a material dividing mechanism, a material pushing mechanism, and a loading mechanism installed on the body from top to bottom, and the receiving plate is arranged under the loading mechanism to receive the firework inner tube falling from the loading mechanism.

[0016] The loading mechanism includes an inverted L-shaped blanking plate, and the corner of the blanking plate is arc-shaped; a blanking trough is arranged on the blanking plate; the material distribution mechanism is located above the blanking trough, and is used to distribute the inner tubes of fireworks into the blanking trough; the material pushing mechanism is located at one end of the upper part of the blanking trough, and is used to push the inner tubes of fireworks in the blanking trough to the corner of the blanking trough.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0018] The upper end of the material receiving through hole is bucket-shaped with a large hole, so the inner tube of the firework can easily fall into the material receiving through hole. When the discharge hole on the discharge plate is staggered with the material receiving through hole, the inner tube of the firework cannot fall and is located in the columnar part of the material receiving through hole. After the material receiving through hole is close to the tube mouth of the firework outer tube and aligned, the discharge hole is aligned with the material receiving through hole, and the inner tube of the firework falls directly into the outer tube of the firework through the discharge hole, so as to realize the loading of the inner tube of the firework. The inner tube of the firework falling from the loading mechanism is collected and sorted by the material receiving plate, and then directly passed into the outer tube of the firework. The transportation path of the inner tube of the firework will not be deviated due to the vibration of the machine, and the loading is more accurate with a low error rate.
