Description

Technical Field

[0001] This invention belongs to the field of automated equipment, specifically an automated filling device for energetic solid granules. Background Technology

[0002] Increasing the loading density of an energetic solid propellant and using high-energy energetic propellant have similar effects on increasing the muzzle velocity of artillery. However, increasing the loading density of an energetic propellant is easier to implement and less costly. Therefore, increasing the loading density of an energetic propellant to improve the power and muzzle velocity of barrel weapons is more feasible.

[0003] Currently, the filling of energetic solid drug particles is mainly achieved manually. The process is as follows: The energetic solid drug particles are weighed according to a prescribed ratio in a weighing pharmacy and placed in a corresponding hopper; the weighed particles are transferred to the filling room; other items to be placed in the drug box are placed inside; the energetic solid drug particles are filled from the hopper into the drug box through a funnel; after filling, the particles are shaken well; the drug shell cap is installed; and the filled drug box is placed on a tray in preparation for subsequent packaging.

[0004] Based on the above process, the current method of manually filling energetic solid drug particles has the following disadvantages: 1. Manual operation is labor-intensive and has a high risk factor; furthermore, the volatile gases emitted by the energetic solid drug particles are harmful to the human body. 2. The posture of the energetic solid drug particles in the medicine box is inconsistent and highly random when filled manually through a funnel, resulting in uneven particle density and low accuracy. 3. The manual filling process involves many repetitive steps, making it cumbersome and inefficient. Summary of the Invention

[0005] The purpose of this invention is to provide an automated filling device for energetic solid drug particles, so as to realize the automated filling process of energetic solid drug particles.

[0006] The technical solution for achieving the objective of this invention is: an automated filling device for energetic solid drug particles, comprising:

[0007] The granule feeding mechanism, mounted on the frame, is used to convey energetic solid granules by vibration.

[0008] The granule feeding mechanism includes:

[0009] The vibrating feed pan, connected to the feed inlet, is fixed on the table of the frame and is used to hold energetic solid granules and convey them to the linear vibrating feeding mechanism.

[0010] A linear vibrating feeding mechanism, connecting a vibrating feed pan and a track-changing mechanism, is used to convey energetic solid drug particles by vibration.

[0011] The filling mechanism is located on both sides of the linear vibrating feeding mechanism and is used to fill the granules into the granule holes of the closely packed mold.

[0012] The track-changing mechanism, located in front of the closely spaced mold, switches the position of the channel to perform vibration feeding and cylinder push rod feeding in different channels respectively, so as to realize the alternating filling of the granules and improve the filling efficiency.

[0013] The significant advantages of this invention compared to existing technologies are:

[0014] (1) The automated filling equipment for energetic solid granules of the present invention adopts a fully automated structural system to realize the automated filling of energetic solid granules, which solves the problems of high risk and dense operation personnel in the filling of energetic materials. At the same time, it is combined with safety designs such as electrostatic detection system and dust removal system to improve the overall safety of equipment and personnel in the production process.

[0015] (2) The automated dense packing equipment for energetic solid drug particles of the present invention can realize the automated packing of two different specifications of energetic drug columns, thereby improving the packing efficiency; and the dense packing mold adopts a hexagonal hole design with two sizes, which effectively reduces the gap between drug particles, making the packing of drug particles more compact and uniform in density.

[0016] (3) In this invention, the filling of energetic solid drug particles is quantitatively controlled by the design of a weighing sensor, so as to ensure the accurate filling of drug particle weight.

[0017] (4) In this invention, the position of channel A and channel B is switched by the design of the track changing mechanism. Vibration feeding and cylinder push rod feeding are carried out in channels A and B respectively, so as to realize the alternating filling of the granules and improve the filling efficiency.

[0024] The terminology used in this invention is for illustrative purposes only and is not intended to limit the invention. The following description, in conjunction with the appendix, further clarifies this concept. Figure 1-5 The following is a detailed description of some embodiments of the present invention.

[0025] The automated filling equipment for energetic solid granules includes a granule feeding mechanism 1, a mold transfer assembly 2, a densely packed mold 3, a frame 4, a profile outer cover 5, a dust collector 6, and an electrostatic detector 7. The granule feeding mechanism 1 and the mold transfer assembly 2 are mounted on the frame 4. The densely packed mold 3 is mounted on the mold transfer assembly 2 and is used to achieve horizontal and vertical movement. The profile outer cover 5 is used to isolate and protect important components, while preventing dust diffusion during the vibratory feeding process. The dust collector 6 removes dust from the profile outer cover 5, reducing the impact of granule dust on the environment and the health of operators. The electrostatic detector 7 detects static electricity generated by friction during the vibratory feeding process. When the static electricity value reaches a warning threshold, an alarm is triggered, reminding the user to immediately perform static electricity removal. Furthermore, as... Figure 1 As shown, in order to improve the filling amount and production capacity of the drug granules, this set of equipment is designed with two sets of closely spaced molds 3, and the filling and feeding are carried out by the feeding mechanism 1.

[0026] Since each set of closely spaced molds 3 needs to be filled with two sizes of granules, each set of closely spaced molds 3 is designed with two sets of feeding mechanisms 1 and mold transfer components 2; these are adapted to the feeding of two sizes of granules, achieving directional and orderly conveying of granules. The two sets of feeding mechanisms and the two sets of mold transfer components 2 are completely identical in structure and function, the difference being that the dimensions differ when adapting to different sizes of granules. For example Figure 2 As shown, the granule feeding mechanism 1 mainly includes a vibrating feeder 11, a linear vibrating feeding mechanism 12, a track changing mechanism 14, and a filling mechanism 13.

[0027] The vibrating feeder 11 is fixed on the platform of the frame 4 and is used to hold energetic solid drug particles and convey them to the linear vibrating feeder 12 via vibration. The linear vibrating feeder 12 uses high-frequency micro-amplitude vibration to move and convey the drug particles in a specific direction, and the conveying speed can be adjusted by changing the amplitude and frequency of the vibration device.

[0028] The linear vibrating feeding mechanism 12 connects the vibrating material tray 11 and the track changing mechanism 14. The linear vibrating feeding mechanism 12 mainly includes a linear track 121, a linear vibrator 122, a vibrator mounting plate 123, and a mounting base 124.

[0029] The linear track 121 is fixed above the linear vibrator 122 for conveying energetic solid particles. The linear vibrator 122 is used to provide the power source for vibration. The mounting base 124 is fixed on the table of the frame 4. The vibrator mounting plate 123 is fixed on the mounting base 124. The linear vibrator 122 is mounted on the vibrator mounting plate 123.

[0030] The filling mechanism 13 mainly includes a cylinder bracket 131, a cylinder 132 fixed on the cylinder bracket 131, and the cylinder bracket 131 installed on the table of the frame 4. In each feeding mechanism 1, a filling mechanism 13 is set on both sides of the linear track 121 of the linear vibration feeding mechanism 12, which is used to fill the granules into the granule holes of the close-packed mold 3 through the telescopic movement of the cylinder 132.

[0031] The track-changing mechanism 14 mainly includes a dual-channel platform 141, a photoelectric sensor 142, a sliding cylinder 143, a baffle 144, and a cylinder support 145. The photoelectric sensor 142 is used to detect the operating position of the cylinder 132, meaning that the granules can only be fully filled into the densely packed mold 3 when the cylinder 132 reaches the designated position. The track-changing mechanism 14 switches the positions of channel A and channel B, performing vibration feeding and cylinder push rod feeding in channels A and B respectively, realizing alternating filling of granules and improving filling efficiency.

[0032] The cylinder bracket 145 is fixed on the table surface of the frame 4, the slide cylinder 143 is fixedly installed on the cylinder bracket 145, and the dual-channel platform 141 is fixedly connected to the slide mechanism of the slide cylinder 143, thereby moving the dual-channel platform 141 by moving the slide.

[0033] The baffle 144 is fixed on the cylinder bracket 145 and is on the same straight line as the linear track 121 in the linear vibration feeding mechanism 12. It is used to block the medicine particles on the linear track 121 to prevent the medicine particles from falling off in the non-filling position.

[0034] The dual-channel platform 141 has two parallel linear channels, namely channel A and channel B. The dual-channel platform 141 is moved by the extension and retraction of the slide cylinder 142, thereby changing the alignment of the channel with the linear track 121. When the slide cylinder 142 is extended, channel A of the dual-channel platform aligns with the linear track 121 for feeding, and the cylinder 132 on the B side of the linear track 121 is aligned with channel B of the dual-channel platform. When channel A of the dual-channel platform 141 is full of granules, the slide cylinder 142 retracts, and the dual-channel platform 141 translates. At this time, the cylinder 132 on the A side of the linear track 121 is aligned with the center of channel A in the dual-channel platform 141. Simultaneously, channel B of the dual-channel platform 141 aligns with the linear track 121 of the linear vibrating feeding mechanism 12, and feeding can continue on channel B.

[0035] like Figure 4 As shown, the mold transfer assembly 2 includes a servo linear module 21, an electric cylinder 22, a weighing sensor 23, and a close-packed mold mounting and clamping mechanism 24. The servo linear module 21 is mounted on the table of the frame 4. The electric cylinder 22 is fixedly mounted on the slider of the servo linear module 21. The servo linear module 21 is used to achieve horizontal linear movement of the close-packed mold 3, thereby allowing the close-packed mold 3 to move horizontally between the two sets of granule feeding mechanisms 1. The electric cylinder 22 is used to achieve vertical linear movement of the close-packed mold 3. The bottom of the weighing sensor 23 is fixed to the slide of the electric cylinder 22, and the top of the weighing sensor 23 is fixed to the close-packed mold mounting and clamping mechanism 24, used to measure the filling mass of energetic solid granules in the close-packed mold 3. The close-packed mold mounting and clamping mechanism 24 is used to mount the close-packed mold 3.

[0036] The close-packed mold 3 is positioned by three positioning pins 26 in the close-packed mold installation clamping mechanism 24 and fixed by two quick presses 25.

[0037] The close-packed mold 3 contains two sizes of hexagonal granule holes. Larger holes are evenly distributed on the outer ring, and smaller holes are evenly distributed on the inner ring. Each of these two sizes of holes needs to be filled with granules of matching size, ensuring that the granules are evenly filled into the close-packed mold 3.

[0038] The dense packing mold 3 uses hexagonal granule holes to maximize the space utilization of the mold and increase the density of the loaded granules.

[0039] The mold transfer component 2 moves the closely spaced mold 3 to align each loading hole with the corresponding filling channel, thus achieving automated filling of the drug particles. The visual inspection system 8 performs positioning calibration to ensure filling accuracy.

[0040] When the densely packed mold 3 passes through the mold transfer mechanism 2 and transfers a certain granule hole to the designated position, at this time, channel A of the dual-channel platform 141, the granule hole of the mold, and the cylinder 132 on side A of the linear track 121 are aligned, and the cylinder push rod extends, realizing the filling of granules into the granule hole of the densely packed mold 3. While the granules are being loaded onto the loading channel A through which the cylinder extends, the B channel is being loaded normally, and the two are carried out in parallel, reducing the loading waiting time.

[0041] The profile cover 5 is set around the mold transfer assembly 2, the closely spaced mold 3, and the frame 4. The profile cover 5 includes a profile frame and a transparent plate. The profile frame is fixedly connected by profiles, and the transparent plate is fixed on the profile frame. The profile cover 5 is used to isolate and protect important components, and at the same time prevent dust from spreading during the vibration feeding process of the granules.

[0042] Dust collector 6 is an explosion-proof baghouse dust collector system, consisting of a dust collection hood, a duct system, and the dust collector itself. The dust collection hood captures dust-laden gas generated during the vibrating conveying of the pharmaceutical particles, ensuring efficient dust collection. The duct system transports the dust-laden gas to the dust collection equipment. The dust collector uses filter bags to intercept dust and employs pulse jet cleaning or mechanical vibration for dust removal. The entire dust collector is explosion-proof, the filter bags use anti-static fibers, and all metal components, including the dust collector housing and ductwork, are grounded throughout. The dust collection hood of the dust collection system connects to the internal space of the profile outer cover 5, and is used to remove pharmaceutical particle dust from the profile outer cover 5, reducing the impact of pharmaceutical particle dust on the environment and the health of operators.

[0043] The electrostatic detector 7 is an explosion-proof non-contact electrostatic detector. Based on the principle of electrostatic induction, it senses the electric field on the surface of the granules and powder through an explosion-proof probe and converts it into a potential value. The electrostatic detector integrates an electrostatic potentiometer, a charge sensor, and a data acquisition module to monitor the electrostatic parameters of objects on the production line in real time and trigger an alarm. The electrostatic detector 7 is installed inside the profile outer cover 5 and is used to detect the static electricity generated by friction during the vibrating feeding process of the granules. When the static electricity value reaches the warning value, it triggers an alarm and reminds that immediate static electricity removal is required.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention.
