Description

Technical Field

[0001] This invention relates to the field of pyrotechnics processing, and more specifically to a pyrotechnics dosing device. Background Technology

[0002] To improve the production efficiency of pyrotechnic products, various gunpowder filling equipment has emerged.

[0003] Existing gunpowder filling equipment, as described in patent application number CN202210008190.6, comprises several gunpowder metering cylinders and several pressing rods that work together. The pressing rods push the gunpowder into the metering cylinders, thus completing the quantitative weighing of the gunpowder. The gunpowder in the metering cylinders can then be dispensed into the pyrotechnic device. However, during the quantitative weighing process, the gunpowder is compacted. If this compacted gunpowder is directly dispensed into the pyrotechnic device, the gunpowder inside will still clump together, making it difficult to distribute the gunpowder evenly at the bottom of the device and affecting the filling effect.

[0004] Therefore, how to evenly distribute gunpowder at the bottom of pyrotechnic devices is a technical problem that urgently needs to be solved. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a pyrotechnic charging device to solve the technical problem that it is difficult to evenly distribute gunpowder at the bottom of the pyrotechnic in the prior art.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: This invention provides a pyrotechnic charging device, comprising: The weighing assembly includes a buffer tray, a weighing tray, and a first driving member. The buffer tray has a buffer through hole. The weighing tray is rotatably mounted on the upper surface of the buffer tray, and the weighing tray has a plurality of weighing through holes along its circumference. The first driving member is connected to the weighing tray and drives the weighing tray to rotate so that the plurality of weighing through holes are aligned with the buffer through hole one by one. The feeding assembly injects gunpowder into each of the weighing through holes; and The conveying assembly includes a carrying tray and a second driving member. The carrying tray is movably disposed on the lower surface of the buffer tray and has several fixed positions for placing cartridges. The second driving member is connected to the carrying tray and drives the carrying tray to move relative to the buffer tray so that the cartridges in the several fixed positions are aligned with the buffer through holes one by one.

[0007] In some embodiments, a plurality of the mounting positions are arranged circumferentially along the tray, and the second drive member is tractively connected to the tray, thereby driving the tray to rotate.

[0008] In some embodiments, a plurality of slots are provided in a one-to-one correspondence among the plurality of mounting positions, and the conveying assembly further includes a plurality of sleeves, each sleeve corresponding to a plurality of slots, and the sleeves are detachably embedded in the slots.

[0009] In some embodiments, the conveying assembly further includes a guide disk, the guide disk cylinder shaft is mounted to the loading disk, and the guide disk has a plurality of guide openings on its outer periphery, and the plurality of guide openings correspond one-to-one with the plurality of slots.

[0010] In some embodiments, the feeding assembly includes a feeding element and a scraping frame, the scraping frame being disposed on the upper surface of the weighing pan and aligning with a plurality of weighing through holes one by one during the rotation of the weighing pan.

[0011] In some embodiments, the feeding device includes a hopper, a flow pump, and a conduit. The hopper is used to store gunpowder. The inlet end of the flow pump is connected to the hopper, and its outlet end is connected to one end of the conduit. The other end of the conduit is aligned with the scraper frame.

[0012] In some embodiments, the weighing tray includes a tray body and a plurality of mounting bases. The tray body is rotatably mounted on the upper surface of the buffer tray, and the plurality of mounting bases are circumferentially mounted to the tray body. A plurality of weighing through holes are correspondingly formed on the plurality of mounting bases.

[0013] In some embodiments, a plurality of mounting grooves are formed on the outer periphery of the disc, and a plurality of mounting seats are embedded in the plurality of mounting grooves in a corresponding manner.

[0014] In some embodiments, the first drive unit includes a motor and a drive shaft, wherein the output shaft of the motor is connected to one end of the drive shaft and the other end of the drive shaft is connected to the disc body.

[0015] In some embodiments, the diameter of the buffer through-hole is 2 to 3 times the diameter of the weighing through-hole.

[0016] Compared with the prior art, the pyrotechnic dosing device provided by the present invention has the following advantages: First, gunpowder is poured into the weighing holes one by one using the feeding assembly. Then, the first driving component drives the weighing pan to rotate. Whenever the weighing hole aligns with the buffer hole, the gunpowder in the weighing hole falls into the buffer hole. The second driving component moves the carrying pan, and whenever the cartridge case in the fixed position aligns with the buffer hole, the gunpowder in the buffer hole falls into the cartridge case, thus completing the gunpowder filling. Because the gunpowder weighed in the weighing holes is first fed into the buffer holes, the gunpowder becomes more loose. Then, the looser gunpowder is fed into the cartridge case, allowing the gunpowder to be evenly distributed at the bottom of the cartridge case, improving the filling quality of the pyrotechnic gunpowder.

Detailed Implementation To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0018] To address the technical problem of gunpowder being difficult to distribute evenly at the bottom of pyrotechnics, this invention provides a gunpowder adding device that can make the gunpowder looser before filling, allowing it to be distributed more evenly at the bottom of the pyrotechnics.

[0019] It should be noted that the pyrotechnic dosing device of the present invention is used for the filling of pyrotechnic propellants. For ease of explanation, in this invention, only the application of the pyrotechnic dosing device to the filling of pyrotechnic propellants will be described.

[0020] Please see Figure 1 , Figure 1This is a schematic diagram of a pyrotechnic charging device according to an embodiment of the present invention. The pyrotechnic charging device includes a weighing assembly 100, a charging assembly 200, and a conveying assembly 300. The weighing assembly 100 includes a buffer tray 110, a weighing tray 120, and a first driving member 130. The buffer tray 110 has a buffer through hole 111. The weighing tray 120 is rotatably mounted on the upper surface of the buffer tray 110, and the weighing tray 120 has a plurality of weighing through holes 1221 along its circumference. The first driving member 130 is connected to the weighing tray 120 and drives the weighing tray 120 to rotate so that the plurality of weighing through holes 1221 are aligned one by one with the buffer through hole 111. The charging assembly 200 pours gunpowder into the plurality of weighing through holes 1221 one by one. The conveying assembly 300 includes a tray 310 and a second drive member (not shown in the figure). The tray 310 is movably disposed on the lower surface of the buffer tray 110 and has several fixed positions for placing cartridges. The second drive member (not shown in the figure) is connected to the tray 310 and drives the tray 310 to move relative to the buffer tray 110 so that the cartridges in the several fixed positions are aligned with the buffer through holes 111 one by one.

[0021] In this embodiment, gunpowder is first poured into the weighing through-hole 1221 one by one using the feeding component 200. Then, the weighing pan 120 is rotated by the first driving component 130. Whenever the weighing through-hole 1221 aligns with the buffer through-hole 111, the gunpowder in the weighing through-hole 1221 falls into the buffer through-hole 111. The second driving component (not shown in the figure) moves the carrying pan 310. Whenever the cartridge in the fixed position aligns with the buffer through-hole 111, the gunpowder in the buffer through-hole 111 falls into the cartridge, thus completing the gunpowder filling. Since the gunpowder weighed in the weighing through-hole 1221 is first fed into the buffer through-hole 111, the gunpowder becomes relatively loose. Then, the relatively loose gunpowder is fed into the cartridge, so that the gunpowder can be evenly distributed at the bottom of the cartridge.

[0022] In some embodiments, a plurality of mounting positions are arranged circumferentially along the tray 310, and a second driving member (not shown in the figure) is connected to the tray 310 and drives the tray 310 to rotate. Since each mounting position is arranged circumferentially along the tray 310, by having the second driving member (not shown in the figure) drive the tray 310 to rotate, the cartridges on each mounting position can be aligned one by one with the buffer through hole 111.

[0023] Based on the above embodiments, in some embodiments, a plurality of mounting positions are provided with a plurality of slots 311 corresponding to each other, and the conveying assembly 300 also includes a plurality of sleeves 320, which correspond one-to-one with the plurality of slots 311, and the sleeves 320 are detachably embedded in the slots 311. The sleeves 320 are used to support the cartridge case, and different sizes of cartridge cases can be adapted by replacing the sleeves 320 with different inner diameters.

[0024] In some embodiments, the conveying assembly 300 further includes a guide disk 330, the guide disk 330 being mounted on a cylindrical shaft to the loading disk 310, and the guide disk 330 having a plurality of guide openings 331 on its outer periphery, with each of the guide openings 331 corresponding to a plurality of slots 311. After the cartridge case is filled with gunpowder, the end cap and the cartridge case can be aligned with each other under the guidance of the guide openings 331.

[0025] In some embodiments, the feeding assembly 200 includes a feeding component 210 and a scraping frame 220. The scraping frame 220 is mounted on the upper surface of the weighing pan 120 and aligns with several weighing through holes 1221 one by one during the rotation of the weighing pan 120. The feeding component 210 feeds gunpowder into the scraping frame 220. Whenever a weighing through hole 1221 aligns with the scraping frame 220, the gunpowder in the scraping frame 220 falls into the weighing through hole 1221, while any excess gunpowder at the top of the scraping through hole is carried away by the scraping frame 220, thereby ensuring the accuracy of gunpowder weighing.

[0026] Based on the above embodiments, in some embodiments, the feeding component 210 includes a hopper 211, a flow pump 212 and a conduit 213. The hopper 211 is used to store gunpowder. The feed end of the flow pump 212 is connected to the hopper 211, and its discharge end is connected to one end of the conduit 213. The other end of the conduit 213 is aligned with the scraper frame 220.

[0027] In some embodiments, the weighing tray 120 includes a tray body 121 and a plurality of mounting seats 122. The tray body 121 is rotatably mounted on the upper surface of the buffer tray 110. The plurality of mounting seats 122 are circumferentially mounted to the tray body 121, and a plurality of weighing through holes 1221 are correspondingly formed on the plurality of mounting seats 122. The tray body 121 drives each mounting seat 122 to rotate, thereby aligning each weighing through hole 1221 with the buffer through hole 111 one by one.

[0028] Based on the above embodiments, in some embodiments, a plurality of mounting grooves 1211 are formed on the outer periphery of the disk body 121, and a plurality of mounting seats 122 are correspondingly embedded in the plurality of mounting grooves 1211. The mounting grooves 1211 serve as limiting positions, so that the mounting seats 122 are fixed on the disk body 121.

[0029] In some embodiments, the first driving element 130 includes a motor 131 and a drive shaft 132. The output shaft of the motor 131 is connected to one end of the drive shaft 132, and the other end of the drive shaft 132 is connected to the disc body 121. The motor 131 drives the drive shaft 132 to rotate, which in turn drives the disc body 121 to rotate.

[0030] In some embodiments, the diameter of the buffer through-hole 111 is 2 to 3 times the diameter of the weighing through-hole 1221. Because the diameter of the buffer through-hole 111 is larger than that of the weighing through-hole 1221, the gunpowder falling from the weighing through-hole 1221 into the buffer through-hole 111 will diffuse radially, making the material inside the buffer through-hole 111 more loose.

[0031] To better understand this invention, the following is combined with... Figures 1 to 4 The technical solution of the present invention will be described in detail below: The feeding component 210 delivers gunpowder into the scraper frame 220. Whenever the weighing through-hole 1221 aligns with the scraper frame 220, the gunpowder in the scraper frame 220 falls into the weighing through-hole 1221, while excess gunpowder at the top of the scraper frame 220 is carried away by the scraper frame 220, thus ensuring the accuracy of gunpowder weighing. Whenever the weighing through-hole 1221 aligns with the buffer through-hole 111, the gunpowder in the weighing through-hole 1221 falls into the buffer through-hole 111. Because the diameter of the buffer through-hole 111 is larger than the diameter of the weighing through-hole 1221, the gunpowder falling from the weighing through-hole 1221 into the buffer through-hole 111 diffuses radially, making the material in the buffer through-hole 111 more loose. The second driving component (not shown in the figure) moves the carrier plate 310. Each time the cartridges in the fixed position are aligned with the buffer through-hole 111, the gunpowder in the buffer through-hole 111 falls into the cartridge, thus completing the filling of the gunpowder. Since the gunpowder weighed in the weighing through-hole 1221 is first fed into the buffer through-hole 111, the gunpowder becomes more loose. Then, the looser gunpowder is fed into the cartridge, so that the gunpowder can be evenly distributed at the bottom of the cartridge.
