Description

Technical Field

[0001] This invention relates to the field of civilian explosives production equipment technology, and more particularly to explosive loading machines. Background Technology

[0002] In the field of electronic detonator manufacturing, the quantitative filling of explosive powder is one of the core processes that determines the detonator's initiation performance and reliability, and it usually requires the use of a specialized charging machine. However, most existing charging equipment uses a method where the propellant nozzle is directly connected to the detonator tube. This charging structure allows for precise control of the charge amount; deviations in the charge amount not only affect the delay accuracy and initiation power of the electronic detonator, resulting in poor product consistency, but may also cause safety hazards due to overfilling. Summary of the Invention

[0003] The technical problem solved by this invention is to provide a drug loading machine that can accurately control the amount of drug loaded.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: a loading machine, including a machine base, a loading lifting assembly, and a loading assembly. A fixed frame is provided on the machine base, and the fixed frame has a loading position and a receiving position. The loading lifting assembly is located on the machine base and corresponds to the loading position. The loading assembly is located on the fixed frame and includes a first loading drive component, a loading sliding assembly, a powder storage assembly, and a hopper on the powder storage assembly. The loading sliding assembly includes a first filter plate, a second filter plate slidably disposed on the first filter plate, and a loading reset component that contacts the first filter plate and the second filter plate respectively. The first loading drive component is connected to the first filter plate to drive the loading sliding assembly to move between the loading position and the receiving position. The first filter plate has a plurality of drug dispensing holes arranged in an array. The second filter plate is provided with a plurality of first temporary storage holes corresponding one-to-one with the dispensing hole. The loading position is provided with a pressing block for pressing against the second filter plate so that the first temporary storage holes are connected to the dispensing hole. The powder storage assembly is located at the receiving position of the fixed frame. The powder storage assembly includes a second driving component for loading and a third filter plate, a fourth filter plate and a fifth filter plate stacked from bottom to top. The third filter plate is provided with a plurality of second temporary storage holes corresponding one-to-one with the first temporary storage holes. The fourth filter plate is provided with a plurality of third temporary storage holes corresponding one-to-one with the second temporary storage holes. The fifth filter plate is provided with a plurality of fourth temporary storage holes corresponding one-to-one with the third temporary storage holes. The fourth filter plate is slidably disposed relative to the medicine hopper and connected to the second driving component for loading fixed on the fixed frame. The bottom end of the medicine hopper is connected to each of the fourth temporary storage holes.

[0005] The beneficial effects of this invention are as follows: This charging machine, through its unique multi-stage temporary storage and linkage control structure, achieves precise control of the powder filling amount, improving the product consistency and safety of electronic detonators. Specifically, through the cooperation of the charging assembly and the charging lifting assembly, and utilizing the mechanical synergy of the pressure block and the charging reset component, the sliding displacement of the second nozzle plate relative to the first nozzle plate is precisely controlled, thereby achieving precise connection and closure between the first temporary storage hole and the charging hole. This mechanically limited quantitative method effectively overcomes the shortcomings of the traditional gravity flow method, which is greatly affected by the flowability of the powder. At the same time, the powder temporary storage assembly adopts a multi-layer stacking and staggered opening design of the third, fourth, and fifth nozzle plates, which, together with the second charging drive component, drives the fourth nozzle plate to slide, eliminating the phenomenon of instantaneous over-spraying. Thus, while ensuring high-precision charging, it reduces safety hazards and meets the high-standard requirements of large-scale automated production of electronic detonators.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0015] Example 1 Embodiment 1 of the present invention is: a loading machine for filling the detonator shell carried by the transport jig 10 with powder.

[0016] Please refer to Figures 1 to 6The charging machine includes a base 1, a charging lifting assembly 2, and a charging assembly 3. The base 1 is equipped with a fixed frame 4, which can be an integral structure. The fixed frame 4 has a charging position 41 and a receiving position 42. The charging lifting assembly 2 is mounted on the base 1 and corresponds to the charging position 41. The charging lifting assembly 2 is used to lift the transport fixture 10 carrying the detonator casing. The charging lifting assembly 2 can use a cylinder, hydraulic rod, electric push rod, motor, etc., as a power source. The charging assembly 3 is mounted on the fixed frame 4 and includes a first charging drive component 31, a charging sliding assembly 32, a powder storage assembly 33, and a hopper 34 mounted on the powder storage assembly 33. The powder-filling sliding assembly 32 includes a first drain plate 321, a second drain plate 322 slidably disposed on the first drain plate 321, and a powder-filling reset member 323 that contacts the first drain plate 321 and the second drain plate 322 respectively. The powder-filling reset member 323 can be a spring, a spring sheet, a rubber sleeve, etc. A first powder-filling drive member 31 is connected to the first drain plate 321 to drive the powder-filling sliding assembly 32 to move between the powder-filling position 41 and the powder-receiving position 42. The first drain plate 321 has a plurality of powder-dispensing holes 3211 arranged in an array. The second drain plate 322 has a plurality of first temporary storage holes 3221 corresponding one-to-one with the powder-dispensing holes 3211. The powder-filling position 41 is provided with a pressing block 4 for pressing against the second drain plate 322. 3. To ensure communication between the first temporary storage hole 3221 and the drug dispensing hole 3211 at the drug loading position 41, the first drug loading drive 31 can be a cylinder, hydraulic rod, electric push rod, motor belt assembly, motor lead screw assembly, etc.; the powder temporary storage assembly 33 is located at the drug receiving position 42 of the fixed frame 4. The powder temporary storage assembly 33 includes a second drug loading drive 331 and a third drain plate 332, a fourth drain plate 333, and a fifth drain plate 334 stacked sequentially from bottom to top. The third drain plate 332 has a plurality of second temporary storage holes 3321 corresponding one-to-one with the first temporary storage hole 3221, the fourth drain plate 333 has a plurality of third temporary storage holes 3331 corresponding one-to-one with the second temporary storage hole 3321, and the fifth drain plate 334... The sprue plate 334 is provided with a plurality of fourth temporary storage holes 3341 corresponding one-to-one with the third temporary storage hole 3331. The fourth sprue plate 333 is slidably disposed relative to the medicine hopper 34 and connected to the second drug loading drive member 331 fixed on the fixed frame 4. The second drug loading drive member 331 drives the fourth sprue plate 333 to move, thereby switching the third temporary storage hole 3331 between two connected states: connecting to the second temporary storage hole 3321 and connecting to the fourth temporary storage hole 3341. The second drug loading drive member 331 can be a cylinder, hydraulic rod, electric push rod, motor belt assembly, motor lead screw assembly, etc. The bottom end of the medicine hopper 34 is connected to each of the fourth temporary storage holes 3341, thereby filling each of the fourth temporary storage holes 3341 with medicine powder.

[0017] In this embodiment, the first driving component 31 and the second driving component 331 have the same driving direction and are perpendicular to the driving direction of the loading lifting assembly 2.

[0018] Please refer to Figures 1 to 4 In one or more embodiments, the drug loading sliding assembly 32 further includes a sliding frame 324. The first leak plate 321 is movably mounted on the sliding frame 324. The first leak plate 321 is indirectly connected to the first drug loading drive member 31 through the sliding frame 324. The fixed frame 4 is provided with a drug loading lifting assembly 35, which is set corresponding to the drug receiving position 42. The drug loading lifting assembly 35 is used to lift the first leak plate 321 at the drug receiving position 42. When the first leak plate 321 is not at the drug receiving position 42, there is a height difference between the second leak plate 322 and the third leak plate 332. Under the lifting action of the drug loading lifting assembly 35, the second leak plate 322 and the third leak plate 332 can achieve surface contact at the drug receiving position 42, so that the drug powder in the second temporary storage hole 3321 falls completely into the first temporary storage hole 3221. The drug loading lifting assembly 35 can be a cylinder, hydraulic rod, electric push rod, motor belt assembly, motor lead screw assembly, etc. The height difference between the second drain plate 322 and the third drain plate 332 can prevent the second drain plate 322 and the third drain plate 332 from rubbing against each other during the process of the drug loading sliding assembly 32 returning to the drug receiving position 42. This helps to extend the service life of the second drain plate 322 and the third drain plate 332. More importantly, it can prevent the friction between the two from generating heat and igniting the drug powder, which helps to ensure production safety.

[0019] Please refer to Figure 1 and Figure 4 The bottom of the discharge hole 3211 is provided with a guide cone surface 3212 and an extension section 3213 that extends into the casing of the detonator to be loaded. When the loading lifting assembly 2 lifts the detonator casing, the guide cone surface 3212 can finely adjust the position of the casing opening, which helps to improve the alignment accuracy between the discharge hole 3211 and the casing opening. The presence of the extension section 3213 can prevent the powder from falling outside the casing, ensuring that all the powder in the discharge hole 3211 can fall into the casing, further ensuring the powder loading accuracy.

[0020] Please refer to Figures 1 to 3 In some embodiments, the loading position 41 is further provided with a third loading drive 44, which is connected to a pressing block 43 to drive the pressing block 43 to press against the second sprue plate 322. The third loading drive 44 can be a cylinder, hydraulic rod, electric push rod, motor belt assembly, motor lead screw assembly, etc. The third loading drive 44 actively drives the pressing block 43, making the timing of the pressing block 43's movement controllable and able to precisely coordinate with the movement of the loading sliding assembly 32, further improving the coordination and accuracy of the loading action. In this embodiment, the third loading drive 44 has the same driving direction as the first loading drive 31.

[0021] Please refer to Figures 1 to 5In some embodiments, the loading machine further includes a loading rotation drive 5 mounted on the fixed frame 4. The loading rotation drive 5 is connected to the powder storage assembly 33 to drive the hopper 34 to rotate laterally. The fourth sump plate 333 has a connecting part 3332 with a connecting hole 3333 on it. The output end of the second loading drive 331 is connected to a connecting post 3311 that engages with the connecting hole 3333. The loading rotation drive 5 can be a motor, a rotary cylinder, etc. The hopper 34 can be rotated, giving it a self-cleaning or emptying function. When it is necessary to change the type of powder or to stop for maintenance, the hopper 34 can be rotated to empty the residual powder, avoiding cross-contamination. The engagement design of the connecting hole 3333 and the connecting post 3311 is a quick-release structure, which allows the powder storage assembly 33 and the second loading drive 331 to both transmit power and separate quickly.

[0022] Please refer to Figure 1 The loading machine also includes a recovery hopper 6 mounted on the machine base 1. The recovery hopper 6 is located on one side of the medicine hopper 34 in the tilting direction to recover the medicine powder in the medicine hopper 34. The recovery hopper 6 enables the collection and utilization of residual medicine powder. Specifically, during the tilting and discharging process of the medicine hopper 34, the recovery hopper 6 can catch the poured-out medicine powder, avoiding waste and environmental pollution caused by the medicine powder directly spilling onto the machine base 1 or the ground. This helps reduce production costs and also meets the requirements of safe production and environmental protection.

[0023] Please refer to Figures 2 to 3 In a preferred embodiment, the output end of the second driving component 331 for loading is equipped with a push-pull force gauge 3312. The connecting post 3311 is indirectly connected to the output end of the second driving component 331 through the push-pull force gauge 3312. In this embodiment, the push-pull force gauge 3312 is an S-type force sensor. The addition of the push-pull force gauge 3312 enables real-time monitoring of the force during the loading process. Since the powder may be compacted, become damp, or stick together in the temporary storage hole, resulting in changes in sliding resistance, by monitoring the push-pull force data, the control system can determine whether the powder flow is smooth, whether there is a risk of jamming, or adjust the driving speed based on the feedback of resistance changes, thereby achieving intelligent fault warning and process parameter optimization, ensuring the stability of the loading quality.

[0024] Please refer to Figure 1 Optionally, the loading machine also includes a loading quantity visual inspection component 7 located above the loading position 41. The loading quantity visual inspection component 7 can be a CCD camera, etc. The loading quantity visual inspection component 7 provides a non-contact online quality inspection method, which can directly take pictures and analyze the height or amount of drug inside the tube after loading, and detect defective products with unqualified loading quantities (such as insufficient drug or excessive drug) in real time.

[0025] Please refer to Figures 4 to 5 The hopper 34 is equipped with a residual drug level detection sensor 8, which can be a CCD camera or similar device. The residual drug level detection sensor 8 automates material management. When the drug powder in the hopper 34 is insufficient, the sensor promptly sends a signal to the control system, prompting the operator to add more material or triggering the automatic feeding system. This prevents empty loading (i.e., no drug in the hopper) due to depleted powder, avoiding ineffective processing and misjudgments in subsequent processes, thus ensuring the continuity and effectiveness of the production line.

[0026] The working process of this drug loading machine is briefly described as follows: The powder in the medicine hopper 34 falls into the fourth temporary storage hole 3341 of the fifth filter plate 334. Because the third temporary storage hole 3331 and the fourth temporary storage hole 3341 on the fourth filter plate 333 are misaligned, the powder remains in the fourth temporary storage hole 3341. The first driving component 31 drives the charging sliding assembly 32 to move to the receiving position 42. The loading lifting assembly 35 drives the first drain plate 321 to rise, so that the second drain plate 322 approaches the third drain plate 332, and the first temporary storage hole 3221 on the second drain plate 322 aligns with the second temporary storage hole 3321 on the third drain plate 332. The second driving member 331 drives the fourth sprue plate 333 to move, so that the fourth temporary storage hole 3341 is connected to the third temporary storage hole 3331 on the fourth sprue plate 333. The powder in the fourth temporary storage hole 3341 falls into the first temporary storage hole 3221 on the second sprue plate 322 through the third temporary storage hole 3331 on the fourth sprue plate 333 and the second temporary storage hole 3321 on the third sprue plate 332. Under the action of the loading reset member 323, the first temporary storage hole 3221 on the second sprue plate 322 is misaligned with the drug dispensing hole 3211 on the first sprue plate 321, so the powder stays in the first temporary storage hole 3221. The second driving unit 331 drives the fourth leak plate 333 to reset, and the fourth temporary storage hole 3341 on the fifth leak plate 334 reconnects with the third temporary storage hole 3331 on the fourth leak plate 333. The third temporary storage hole 3331 is refilled with powder through the fourth temporary storage hole 3341. The loading lifting assembly 35 descends, and the first sump plate 321 descends; The first driving component 31 drives the charging sliding assembly 32 to move to the charging position 41; The loading lifting assembly 2 lifts the transport jig 10 of the loading tube shell, so that the tube shell opening connects with the loading hole 3211; The third driving component 44 drives the pressing block 43 to press against the second leak plate 322, so that the first temporary storage hole 3221 is connected to the drug discharge hole 3211, and the drug powder in the first temporary storage hole 3221 falls into the tube shell through the drug discharge hole 3211. The visual inspection component 7 detects the filling status of the medicine powder in each tube shell.

[0027] The above are merely optional embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
