Description

Technical Field

[0001] This utility model relates to the field of gunpowder quantity detection, specifically a gunpowder quantity detection device. Background Technology

[0002] Fireworks gunpowder loading machines are typically used to fill the inner tubes of fireworks. During the loading process, gunpowder is inserted into the corresponding feed hole in the inner tube and then pressed into the firework. The gunpowder in the loading box of the fireworks gunpowder loading machine is usually added manually. Adding too much gunpowder will render the scraper unusable, while adding too little requires multiple additions, necessitating the operator to add gunpowder in small amounts frequently. Utility Model Content

[0003] The present invention aims to provide a gunpowder dosage detection device to realize automatic addition of gunpowder based on the detection of the dosage.

[0004] To solve the above technical problems, the specific solution adopted by this utility model is as follows:

[0005] A gunpowder quantity detection device includes a fireworks powder-building machine, a mixing device and a mounting box on the fireworks powder-building machine, a temporary storage cavity for storing gunpowder between the mixing device and the mounting box, a feeding plate controlled by a PLC controller of the fireworks powder-building machine at the bottom of the temporary storage cavity, a rotating rod driven by a first cylinder to slide horizontally on the mounting box, a scraper composed of a first scraper and a second scraper on the circumferential surface of the rotating rod inside the mounting box, a laser sensor on the top of the mounting box, the probe of the laser sensor being located at the top inside the mounting box, a measuring groove for the laser sensor probe to measure on the second scraper, the measuring groove penetrating the second scraper, and the laser sensor being electrically connected to the PLC controller.

[0006] The bottom of the mounting box has an arc-shaped structure on both sides, and the laser sensor is located directly above the scraper when it moves to its limit position.

[0007] The first scraper and the second scraper are L-shaped with the axis of the rotating rod as the junction.

[0008] The included angle between the first scraper and the second scraper is 90°.

[0009] Due to the adoption of the above technical solution, this utility model has the following beneficial effects:

[0010] By installing a laser sensor on the mounting box to detect the remaining amount of gunpowder inside, and by setting a measuring groove on the first scraper for the laser sensor probe to pass through, the remaining gunpowder in the mounting box can be monitored after the gunpowder has been added. This utility model has a simple and reasonable structure, and can effectively detect the gunpowder in the mounting box, thereby replacing the manual gunpowder adding. Attached Figure Description

[0015] like Figure 1 As shown, a gunpowder quantity detection device includes a fireworks powder-building machine 1, the specific structure of which is as follows: Figure 1 As shown, the fireworks gunpowder filling machine 1 is used to fill the inner tube of fireworks with gunpowder. The fireworks gunpowder filling machine 1 is equipped with a mixing device 2 and a mounting box 3. The mixing device 2 is existing technology. Gunpowder is fed into the mixing device 2 through two feed ports on the top of the mixing device 2 for mixing. There is a temporary storage chamber (not shown in the figure) between the mixing device 2 and the mounting box 3 to store gunpowder. The fireworks gunpowder mixed by the mixing device 2 will enter the temporary storage chamber for further use. The bottom of the temporary storage chamber is equipped with a feeding plate controlled by the PLC controller of the fireworks gunpowder filling machine 1. The feeding plate is a flip-plate structure and is controlled by the PLC controller. The mounting box 3 is equipped with a rotating rod 4 that slides horizontally driven by a first cylinder 9. The rotating rod 4 is located on the circumferential surface inside the mounting box 3 and is equipped with a scraper composed of a first scraper 5 and a second scraper 6. Figure 3As shown, a laser sensor 7 is provided on the top of the mounting box 3. The probe of the laser sensor 7 is located at the top inside the mounting box 3. The second scraper 6 is provided with a measuring groove 8 for the probe of the laser sensor 7 to measure. The measuring groove 8 passes through the second scraper 6. The laser sensor 7 is electrically connected to the PLC controller. The specific principle of the laser sensor 7 is to measure the distance between the gunpowder and the probe of the laser sensor 7 located between the first scraper 5 and the second scraper 6, thereby determining whether the amount of gunpowder stored inside is sufficient for loading. When the laser sensor 7 detects that the required amount of gunpowder is insufficient, it transmits a signal to the PLC controller, thereby controlling the feeding plate to flip, so that the gunpowder in the temporary storage cavity enters the mounting box 3 for use. In this invention, the scraper scrapes the gunpowder inside the mounting box into the feeding hole at the bottom of the mounting box. The inner tube of the fireworks is located below the feeding hole, and the positions of the inner tube and the feeding hole correspond to each other. After the gunpowder enters the inner tube, the pressure plate and pressure rod controlled by the upper cylinder press it into the inner tube of the fireworks. The two sides of the bottom of the mounting box 3 are arc-shaped. The laser sensor 7 is located directly above the scraper when it moves to the limit position. The limit position refers to the first scraper 5 and the second scraper 6 being L-shaped with the axis of the rotating rod 4 as the intersection point driven by the first cylinder 9. The included angle between the first scraper 5 and the second scraper 6 is 90°.

[0016] The method of using this utility model is briefly described as follows:

[0017] In use, the gunpowder enters the mixing device 2 and, after mixing, enters the temporary storage chamber for further use. The scraper, driven by the first cylinder 9, scrapes the gunpowder into the feeding hole and into the inner tube of the fireworks for loading. The laser sensor 7 transmits a signal to the PLC controller by measuring the amount of gunpowder remaining after each scraping. If the distance between the probe of the laser sensor 7 and the gunpowder increases, it indicates that the amount of gunpowder has decreased. At this time, the PLC controller controls the feeding plate to flip, so that the gunpowder in the temporary storage chamber enters the mounting box 3 for the scraper to use, thus achieving the purpose of detecting the amount of gunpowder.
