Description

Technical Field

[0001] The utility model belongs to the technical field of fireworks and firecrackers production, in particular to a powder filling mould for firecracker and firecracker medicine cakes. Background Art

[0002] Fireworks and firecrackers refer to arts and crafts made from pyrotechnic powder as raw materials. They can be divided into fireworks and firecrackers. They are entertainment products that burn (explode) through the action of ignition sources and are accompanied by sound, light, color, smoke, fog and other effects. In real life, in the process of making firecrackers and fireworks, a charging mold is usually used to load gunpowder powder into the cartridge of the medicine cake. However, most charging molds are not equipped with auxiliary feeding mechanisms. The gunpowder powder in the mold is only poured into the cartridge through the medicine hole opened at the bottom. This method is not only slow in loading efficiency, but also has a large friction between the gunpowder powder, which easily causes the medicine hole to be blocked and unable to load.

[0003] A Chinese patent document (application publication number CN218764893U) discloses a powder charging mold for firecracker and fireworks medicine cakes, which includes a cylinder body and a partition plate arranged at the bottom of the cylinder body, wherein the partition plate is provided with a plurality of medicine charging holes corresponding to each cylinder in the medicine cake, and the bottom of the cylinder body is provided with a circle of sleeves formed by guide edges and matching the outer shape of the medicine cake.

[0004] It can be seen that the patent document cited above also has the same problem. It does not have an auxiliary feeding mechanism, and only pours the gunpowder powder in the cylinder into the cartridge case through the medicine hole opened at the bottom of the cylinder. This method not only has a slow loading efficiency, but also has a large friction between the gunpowder powder, which can easily cause the medicine hole to be blocked and unable to load.

[0012] As a preferred embodiment, a plurality of medicine charging holes are provided at the inner bottom end of the mold box, and the medicine charging holes are snap-fitted and connected with the medicine cartridge.

[0013] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0014] The charging mold for firecracker and fireworks powder cake benefits from the design of the handle, the connecting plate, the tamping rod and the spring. The handle is held and the connecting plate is driven to move downward, and the connecting plate drives the tamping rod to move downward, thereby pouring the gunpowder powder in the mold box into the powder cake assembly. Then, the powder is reset under the elastic action of the spring, and the powder is loaded again in the same way. This method can assist the charging of the gunpowder powder, not only increasing the charging efficiency, but also preventing the gunpowder powder from clogging the powder hole and making it impossible to load the powder.

[0015] By providing a twisting knob, a screw rod and a scraper, after the charge is loaded, the baffle is opened and the twisting knob is rotated, and the twisting knob drives the scraper to move outwards through the screw rod, so that it is convenient to clean and collect the excess gunpowder powder in the mold box and avoid the waste of gunpowder powder.

The bottom plate 201, the medicine cartridge 202 and the partition plate 203 are all made of paper material.

[0029] The present embodiment provides that a limit block 15 is installed at the bottom end of the connecting rod 4, the top end of the limit block 15 is fixedly connected to the bottom end of the spring 5, the top end of the spring 5 is fixedly connected to the bottom end of the first connecting block 3, both sides of the front of the mold box 1 are equipped with sliders 13, and one side of the two sliders 13 is commonly provided with a baffle 14, the shape of the slider 13 is L-shaped but not limited to the L-shape, and can also be other shapes, as long as it can play a limiting and guiding role for the baffle 14, the front of the mold box 1 is provided with a slide groove adapted to the slider 13, the slider 13 is slidably connected to the slide groove, a plurality of charging holes 101 are provided at the inner bottom end of the mold box 1, and the charging holes 101 are snap-connected with the cartridge 202, the charging holes 101 correspond to the number and position of the cartridge 202 and the tamping rod 9, and the diameter of the tamping rod 9 is smaller than the inner diameter of the cartridge 202.

[0030] How it works

[0031] The medicine cake assembly 2 is engaged with the charging hole 101 at the bottom end of the mold box 1, and the top of the medicine cartridge 202 is located at the same horizontal plane as the inner bottom end of the mold box 1. Then, the handle 8 is held and moved downward. The handle 8 moves downward to drive the connecting plate 7 to move downward. The connecting plate 7 moves downward to stretch the spring 5, and at the same time drives the tamping rod 9 to move downward. The gunpowder powder in the mold box 1 is poured into the medicine cartridge 202 through the tamping rod 9. Then, the force is retracted, and the connecting plate 7 is driven to move in the opposite direction under the elastic action of the spring 5. Similarly, the handle 8 is moved downward again to tamp the material. This cycle is repeated many times. In this way, the gunpowder powder can be assisted in charging, which not only increases the charging efficiency, but also avoids the gunpowder powder from clogging the medicine hole and making it impossible to charge. After the charging is completed, the baffle 14 is moved upward to open it, and then the knob 11 is rotated. The rotation of the knob 11 drives the scraper 12 to move outward through the screw rod 10. In this way, it is convenient to clean and collect the excess gunpowder powder in the mold box 1 to avoid wasting gunpowder powder.
