[0003] At present, the main method for measuring the charge during initiating explosive production is constant volume measurement. The accuracy of constant volume measurement is mainly determined by the uniformity of the particle size of the medicament in the charging device and the apparent density.

However, due to different granulation and screening of the medicament, the size of the medicament particles is not necessarily uniform, and there are mixed medicaments (such as needle-sticking medicaments and excitation medicaments).

[0028] In order to more clearly illustrate the technical solutions in the embodiments of the present application or the prior art, the drawings needed in the embodiments will be briefly introduced below. Obviously, the drawings in the following description are only some embodiments of the present application, and other drawings can be obtained by those skilled in the art without creative effort on the basis of these drawings.

[0030] Figure 2 is a top view of the charging device for the production of the initiating explosive provided by the embodiments of the present application.

DETAILED DESCRIPTION

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0033] See Figure 1 , Figure 2 This invention provides a charging device for producing pyrotechnic products, such as... Figure 1 , Figure 2 As shown, the device may include:

[0034] Frame 1, which is used to support various components;

[0035] A loading unit is connected to the frame 1; the loading unit includes a loading device 2 and a rotary drive assembly 3; the loading device 2 is connected to the rotary drive assembly 3; the rotary drive assembly 3 is used to drive the loading device 2 to swing when the drug accumulates in the loading device 2.

[0036] The medicine collection unit 4 is connected to the frame 1 and located below the side of the medicine loading device 2; the rotary drive assembly 3 is also used to drive the medicine loading device 2 to rotate after the medicine loading is completed, so as to pour the remaining medicine in the medicine loading device 2 into the medicine collection unit 4.

[0037] The metering method for loading explosives in the production of pyrotechnics is mainly constant volume metering. The accuracy of constant volume metering is directly determined by the particle size uniformity and pseudo density of the explosive in the loading device 2. During the production of pyrotechnics, the explosive in the loading device 2 will gradually decrease. For example, the most common constant volume spoon-shaped loading device 2 will generate pits at the scooping point, and the constant volume metering plate loading device 2 will generate pits near the leakage hole. The change in explosive accumulation will affect the pseudo density of the explosive, thus affecting the loading accuracy.

[0038] The pyrotechnics production charging device provided in this application embodiment allows the charging device 2 to rotate under the drive of the rotary drive assembly 3. When the agent inside the charging device 2 accumulates, the rotary drive assembly 3 can drive the charging device 2 to swing appropriately, causing the agent in the charging machine to flow relatively, smoothing out the accumulation angle caused by the charging, improving the charging accuracy during pyrotechnics production, and improving product quality.

[0039] Meanwhile, the rotating driving assembly 3 provided by the embodiment of the present application can also determine a larger rotating angle of the charging device 2 after one-time charging is completed, so that the remaining charge in the charging device 2 can be poured into the charge pouring collecting unit 4. Compared with the manual remaining charge removing mode (such as a quick-release design of the charging device and manual taking and placing) and the knocking and vibrating charging device, the device has a simple structure and can effectively complete the mixing and pouring of the initiating explosive in the charging device 2. The device can effectively avoid the stratification of the charge, significantly improve the precision in the constant-volume charging process, and improve the product quality. The safety in the production process of the initiating explosive is effectively improved.

[0040] The charging device 2 provided by the embodiment of the present application can rotate under the driving of the rotating driving assembly 3. In order to enable the charging device 2 to rotate smoothly, the embodiment of the present application can provide that the rack 1 is provided with a rotating support 5, the rotating support 5 is hinged with a rotating shaft 6, the rotating shaft 6 is connected with a mounting plate 7, and the charging device 2 is fixedly connected with the mounting plate 7.

[0041] In order to prevent sparks from being generated in the use process of the rotating driving assembly 3 and causing safety hazards, the embodiment of the present application can provide that the rotating driving assembly 3 comprises an explosion-proof servo motor 31 and a speed reducer 32, the speed reducer 32 is connected with the rack 1 through a motor support 8, the explosion-proof servo motor 31 is connected with the speed reducer 32, and the speed reducer 32 is connected with the rotating shaft 6 through a shaft coupling 33.

[0042] The charge pouring collecting unit 4 provided by the embodiment of the present application is used for collecting the remaining charge poured out of the charging device 2. Specifically, the charge pouring collecting unit 4 comprises a charge pouring funnel 41 connected with the rack 1. The charge pouring funnel 41 can prevent the charge from overflowing during the pouring process.

[0043] In order to further collect the charge in the charge pouring funnel 41, the embodiment of the present application can also provide that the charge pouring collecting unit 4 further comprises a collecting cup 42 and a tray 43, the collecting cup 42 is arranged on the tray 43 in a free state, and the opening of the collecting cup 42 is opposite to the lower end of the charge pouring funnel 41. The remaining charge can enter the collecting cup 42 through the charge pouring funnel 41, and the collecting cup 42 placed on the tray 43 in a free state can be timely transferred after the charge is collected and the empty collecting cup 42 is replaced.

[0044] In order to further improve the collection efficiency and prevent the charge from overflowing, and at the same time not to affect the normal taking and placing of the collecting cup 42, the embodiment of the present application can also provide that the charge pouring collecting unit 4 further comprises a jacking cylinder 44, and the tray 43 is connected with the piston rod of the jacking cylinder 44.

[0045] When the device stops producing during use, the jacking cylinder 44 extends to make the collection medicine cup 42 close to the medicine pouring funnel 41, the explosion-proof servo motor 31 drives the rotating shaft 6 to make the medicine loading device 2 rotate at a large angle towards the medicine pouring funnel 41, so that the remaining medicine of the medicine loading device 2 flows into the collection medicine cup 42 on the tray 43 through the medicine pouring funnel 41, and after the medicine pouring is completed, the explosion-proof servo motor 31 drives the rotating shaft 6 to reset the medicine loading device 2, and the jacking cylinder 44 descends to make the collection medicine cup 42 away from the medicine pouring funnel 41, and the medicine pouring process is completed.

[0046] It can be understood that the height of the medicine loading device 2 is higher than the height of the medicine surface, and the internal medicine will not flow out when swinging back and forth. Because the swing amplitude of the medicine loading device 2 required to eliminate the accumulation of different medicines is different when the accumulation is generated, in order to improve the universality of the device provided by the present application, the embodiment of the present application can also provide that the rotating drive assembly 3 is used to drive the medicine loading device 2 to swing within a target swing angle range when the medicine in the medicine loading device 2 generates accumulation; the target swing angle is determined according to the rheological property of the medicine. The rotation angle during the swing mixing can be adjusted according to the rheological property of the medicine.

[0047] In order to further improve the intelligence of the device provided by the embodiment of the present application, and to further free the hands of personnel and reduce the labor intensity of workers, the controller can also be provided in the embodiment of the present application, the controller is communicatively connected with the rotating drive assembly 3, and the controller is used to control the swing trigger time and / or swing rate and / or swing angle of the rotating drive assembly 3. The swing trigger time when the rotating drive assembly 3 starts to swing and ends to swing can be controlled by the pre-stored program of the controller, the swing rate of the rotating drive assembly 3 can also be controlled, and the angle of the swing of the rotating drive assembly 3 can also be controlled. The pre-stored program can be determined according to the rheological property of different medicines during loading.

[0048] Because in actual use, due to different temperatures and humidities of the on-site processing environment, the medicine may not completely install the corresponding accumulation generated by its own rheological property, and some unpredictable accumulation states may occur. In order to timely discover the accumulation of the medicine and timely eliminate the accumulation by driving the medicine loading device 2 to swing, the image acquisition assembly can be provided in the embodiment of the present application, the image acquisition assembly is communicatively connected with the controller, and the image acquisition assembly is used to acquire a target image in the medicine loading device 2, so that the controller determines the swing trigger time and / or the swing rate and / or the swing angle according to the target image.

[0049] Specifically, the controller determines the swing trigger time and / or the swing rate and / or the swing angle according to the target image, which includes:

[0050] The target image is compared with a plurality of case images to determine a target case image with the highest similarity to the target image; the plurality of case images are stored in a case image library, and each case image corresponds to a stacking angle of a medicament;

[0051] The stacking angle corresponding to the target case image is determined as a target stacking angle;

[0052] The target stacking angle is used to determine the swing triggering time and / or the swing rate and / or the swing angle.

[0053] In the implementation of the above functions, a large number of case images can be obtained in the actual generation process. For example, after a certain medicament is stacked during the charging process, the image after stacking can be obtained as a case image. Then, the stacking angle formed by stacking can be obtained by measurement, and the swing rate and / or swing angle required to eliminate the stacking angle can be determined by experiment. Finally, the stacking angle and the required swing rate and / or swing angle are stored as part of the case image properties. In a similar way, a plurality of case images corresponding to different stacking angles of each medicament can be obtained, and a plurality of case images of different types of medicaments and their corresponding stacking angles can also be obtained. All case images and corresponding stacking angles are stored in a case image library.

[0054] In actual use, the controller can first determine the type of the medicament being charged. After the image acquisition component obtains the target image, the target image can be compared with each case image corresponding to the type in the case image library. After the target case image with the highest similarity is determined, the stacking angle corresponding to the target case image can be obtained. The controller can determine the swing triggering time and / or the swing rate and / or the swing angle according to the value of the stacking angle.

[0055] In summary, the charging device for initiating explosive production provided in the present application can effectively improve the precision and quality of charging by eliminating medicament stacking through swinging, which only causes relative flow of the medicament and does not cause stratification. The device can be applied to medicaments with different flow properties by adjusting the rotation angle during mixing, and has strong versatility. The device can automatically complete the medicament pouring operation after production by using an explosion-proof servo motor, which solves the safety problem of manual medicament pouring and improves the safety of the initiating explosive production process. At the same time, the device has a simple structure, and only one servo motor is used to simultaneously satisfy the medicament shaking and pouring operations during initiating explosive production. The device is worth popularizing and using on a large scale.
