Description

Technical Field

[0001] This invention relates to the field of emulsion explosives technology, and more particularly to an emulsion explosives loading and production system. Background Technology

[0002] With technological advancements, the production of emulsion explosives has gradually replaced manual labor with highly automated equipment. This change not only reduces the number of personnel operating in hazardous positions but also significantly minimizes safety risks associated with human intervention. Consequently, most packaged emulsion explosive production processes often utilize continuous-production rotary wire clamping loading machines for forming and loading plastic film-packaged explosive rolls. The advantages of this loading machine are: it enables continuous production while ensuring stable weight of the loaded explosive rolls.

[0003] However, this loading method, during the commissioning of the loading machine or at startup, requires adjustments to the quality of the cartridge clipping, the weight of the loaded cartridges, the length of the cartridges, and the quality of the heat-sealing of the plastic film side seal. This results in a large number of cartridges with empty film or those that are substandard in weight, density, or appearance. Furthermore, to sort these substandard cartridges, additional personnel must be assigned to pick them from the stopped conveyor belt, increasing labor costs and reducing work efficiency. Summary of the Invention

[0004] In view of the above-mentioned defects or deficiencies, the purpose of this invention is to provide an emulsion explosive loading production system.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: An emulsion explosive charging production system includes: a charging mechanism, a pressing mechanism for pressing and cutting rolled explosive rolls installed above the output end of the charging mechanism, an explosive roll conveyor belt installed below the pressing mechanism, wherein an openable and closable explosive blocking device is installed at one end of the explosive roll conveyor belt, and an output belt for outputting finished products is provided at the other end of the explosive roll conveyor belt, and an automatic blowing device for blowing the explosive rolls is provided at the output end of the pressing mechanism.

[0006] The medicine-blocking device includes: a mounting frame disposed at the end of the medicine roll conveyor belt, a baffle plate is hingedly mounted on the mounting frame, and a power device for pushing the baffle plate to rotate is mounted on one side of the baffle plate.

[0007] The power unit includes: a medicine-blocking device cylinder, the movable end of which is hinged to a medicine-blocking device connecting rod; a rotating shaft is provided along the length of the baffle, the rotating shaft is mounted on the mounting baffles on both sides, and passes through the mounting baffles to be fixedly connected to the end of the medicine-blocking device connecting rod by a fixing member; the medicine-blocking device cylinder is connected to a compressed air switch for the medicine-blocking device cylinder pipeline; when the movable end of the medicine-blocking device cylinder moves, it drives the medicine-blocking device connecting rod to move back and forth, pushes the rotating shaft to rotate, drives the baffle to rotate and open and close, and collects waste medicine in accordance with the transmission direction of the medicine roll conveyor belt.

[0008] Waste drug collection containers are installed below the baffle to collect waste drugs.

[0009] The automatic purging device includes: a purging nozzle disposed on the output side of the pressing mechanism; the purging nozzle is mounted on one side of the medicine roll conveyor belt via a bracket; the purging nozzle is connected to an automatic purging device air circuit pipe and an air circuit switch; and the compressed air pipeline is connected to a compressed air reservoir to provide compressed air to the purging nozzle.

[0010] The medicine roll conveyor belt is equipped with a transmission mechanism, which is connected to the medicine roll conveyor belt. The transmission mechanism is equipped with a forward and reverse button and a forward and reverse rotation switch. When the machine is first turned on and the medicine rolls are being tested, the medicine roll conveyor belt reverses, closes the compressed air valve in the medicine roll blocking cylinder line, the medicine blocking device cylinder retracts, and drives the medicine blocking device connecting rod to rotate, while simultaneously driving the baffle to rotate counterclockwise, causing the unqualified medicine rolls to flow back into the waste medicine collection container. Once the medicine rolls are tested and found to be qualified, the medicine roll conveyor belt rotates forward. At the same time, the compressed air valve in the medicine roll blocking cylinder line is opened, the cylinder rod extends, and drives the medicine blocking device connecting rod to rotate, while simultaneously driving the baffle to rotate clockwise. Qualified medicine rolls flow into the discharge belt.

[0011] The drug loading mechanism includes: a drug loading machine workbench, a drug delivery pipe on the drug delivery pipe, a hot melt adhesive pipe on the drug delivery pipe, a drug tablet film guide shaft and a drug roll forming device on the hot melt adhesive pipe, a hot melt adhesive pump connected to the hot melt adhesive pipe, and a heat-sealed cylindrical film structure after the hot melt adhesive pipe is loaded.

[0012] A power distribution cabinet is installed above the workbench of the loading machine, and a loading operation screen is installed on the power distribution cabinet.

[0013] The pressing mechanism includes: a rotatable large turntable, on the upper surface of which is provided a wire reel and a wire reversing and punching machine connected to the wire reel; a wire punching machine cutter is provided below the large turntable; and an automatic blowing device is provided on one side of the wire punching machine cutter. After heat sealing, the cylindrical film is driven by the rotation of the large turntable, and the emulsion explosive is packaged into a roll under the action of the wire reversing and punching machine, the card making machine, the wire punching machine cutter, and the kicking roll.

[0014] A base is installed at the center of the large turntable.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention provides an emulsion explosive loading production device. By incorporating a purging tool, the compressed air pipeline valve can be quickly opened simultaneously when the explosive cartridge becomes stuck, allowing the purging equipment to target and eliminate the stuck fault. This reduces material and raw material waste caused by frequent machine restarts and shutdowns, simplifies operation, and reduces the safety hazards of repetitive manual operations. Additionally, a cartridge-blocking device guides cartridges that are empty, have unacceptable weight, density, or appearance, ensuring they automatically flow into the collection container. Once the loading machine is properly adjusted, opening the cylinder operation control valve extends the cylinder rod, causing the connecting rod to lift the baffle and adjust the conveyor belt to rotate forward, preventing the cartridges from scattering and ensuring that qualified cartridges automatically flow into the next conveyor belt or the next process step.

Detailed Implementation

[0019] The present invention will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the protection scope of the present invention.

[0020] like Figure 1 , 2 As shown, the present invention provides an emulsion explosive charging production apparatus, comprising: an emulsion explosive charging production system, including: a charging mechanism, wherein a pressing mechanism for pressing and cutting rolled explosive rolls is installed above the output end of the charging mechanism, and an explosive roll conveyor belt 16 is installed below the pressing mechanism, wherein an openable and closable explosive blocking device is installed at one end of the explosive roll conveyor belt 16, and an output belt 26 for outputting finished products is provided at the other end of the explosive roll conveyor belt 16, and an automatic blowing device for blowing the explosive rolls is provided at the output end of the pressing mechanism.

[0021] like Figure 3-6 As shown, the medicine-blocking device includes: a mounting frame disposed at the end of the medicine roll conveyor belt 16, a baffle 25 hingedly mounted on the mounting frame, and a power device for pushing the baffle 25 to rotate mounted on one side of the baffle 25. Exemplarily, the power device includes: a medicine-blocking device cylinder 19, a medicine-blocking device connecting rod 20 hinged to the movable end of the medicine-blocking device cylinder 19, a rotating shaft 28 disposed along the length of the baffle 25, the rotating shaft 28 being mounted on mounting baffles 29 on both sides, and passing through the mounting baffles 29 and being fixedly connected to the end of the medicine-blocking device connecting rod 20 by a fixing member 30; the medicine-blocking device cylinder 19 is connected to a compressed air switch for the medicine-blocking device cylinder pipeline; when the movable end of the medicine-blocking device cylinder 19 moves, it drives the medicine-blocking device connecting rod 20 to move back and forth, pushing the rotating shaft to rotate, causing the baffle 25 to rotate and open / close, coordinating with the transmission direction of the medicine roll conveyor belt 16 to collect waste medicine.

[0022] Preferably, the automatic purging device includes: a purging nozzle 13 disposed on the output side of the pressing mechanism, the purging nozzle 13 being mounted on one side of the medicine roll conveyor belt 16 via a bracket, the purging nozzle 13 being connected to an automatic purging device air passage pipe 14 and an air passage switch 15, the automatic purging device air passage pipe 14 being connected to a compressed air tank 17 to provide compressed air to the purging nozzle 13.

[0023] In order to collect waste medicine, a transmission mechanism is provided on the medicine roll conveyor belt 16. The transmission mechanism is connected to the medicine roll conveyor belt 16. The transmission mechanism is provided with a forward and reverse button and a forward and reverse rotation switch. When the machine is first turned on and the medicine rolls are being tested, the medicine roll conveyor belt 16 reverses, closes the compressed air valve of the medicine roll blocking cylinder pipeline, the medicine blocking device cylinder 19 retracts, drives the medicine blocking device connecting rod 20 to rotate, and drives the baffle 25 to rotate counterclockwise, causing the unqualified medicine rolls to flow back into the waste medicine collection container 21. After the medicine rolls are tested and found to be qualified, the medicine roll conveyor belt 16 rotates forward. At the same time, the compressed air valve of the medicine roll blocking cylinder pipeline is opened, the cylinder rod extends, and drives the medicine blocking device connecting rod 20 to rotate, while driving the baffle 25 to rotate clockwise. Qualified medicine rolls flow into the discharge belt 26.

[0024] In this invention, the drug loading mechanism includes: a drug loading machine workbench 1, a drug delivery pipe 2 on the workbench 1, a hot melt adhesive pipe 6 on the drug delivery pipe 2, a drug tablet guide shaft 3 and a drug roll forming device 7 on the hot melt adhesive pipe 6, a hot melt adhesive pump 23 connected to the hot melt adhesive pipe 6, and a drug loading switch 22 on the hot melt adhesive pump 23. After the hot melt adhesive pipe 6 is loaded with material, a heat-sealed cylindrical film structure 8 is formed.

[0025] Furthermore, a power distribution cabinet 4 is installed below the loading machine workbench 1, and a loading operation screen 5 is installed above the loading machine workbench 1. This allows for real-time monitoring of the device's operating status.

[0026] The pressing mechanism of this invention includes: a rotatable large turntable 11, on the upper surface of which is a wire reel 9 and a wire reversing and punching machine 10 connected to the wire reel 9; a wire punching machine cutter 12 is located below the large turntable 11; an automatic blowing device is located on one side of the wire punching machine cutter 12; after heat sealing, the cylindrical film 8 is driven by the rotation of the large turntable 11, and the emulsion explosive is packaged into a cartridge under the action of the wire reversing and punching machine 10, the card making machine, the wire punching machine cutter 12, and the kicking tape 27; the wire reversing and punching machine 10, the card making machine, and the wire punching machine cutter 12 are all connected to a power mechanism through a compressed air pipeline 24. A rotatable shaft is installed at the center of the large turntable 11, and the shaft is mounted on a base 18 through bearings; the shaft is connected to a motor, and the rotation of the motor drives the large turntable 11 to rotate.

[0027] The receiving belt, where the medicine rolls first fall, is configured to operate in both forward and reverse directions. Empty rolls (without material) or defective rolls with material, generated before startup or during equipment testing, flow backward along the belt to a dedicated collection container at the end of the belt. Once the filling machine is running normally, the belt direction is set to forward rotation, allowing qualified medicine rolls to flow to the next belt or process. However, this method has a drawback: during machine testing, the reverse rotation of the receiving belt, combined with the force of the rotating filling machine turntable, causes a large number of empty rolls or rolls with substandard weight, density, or appearance to fall haphazardly onto the reverse-rotating belt, lacking order. Simultaneously, the sudden change in belt direction during forward rotation, combined with the inertial force of the high-speed rotating filling machine turntable, can cause some qualified medicine rolls to be thrown off the belt, posing a safety hazard. To address this, we specifically designed a reverse belt automatic medicine roll blocking device 17. When the medicine loading machine is started and tested, the cylinder rod 16 in the device retracts, and the medicine roll blocking baffle in the device guides empty films or medicine rolls that are not up to standard in weight, density, or appearance, allowing them to automatically flow into the collection container. After the medicine loading machine is tested and tested, the cylinder operation control valve is opened, the cylinder rod in the device extends, and the connecting rod drives the baffle to stand up, adjusting the medicine roll conveyor belt to rotate in the forward direction, preventing the medicine rolls from being scattered and allowing qualified medicine rolls to automatically flow into the next belt or the next process.

[0028] Meanwhile, during the operation of rotary wire-clamping and loading machines, issues such as wire feeding jamming and clamping often occur, leading to unsuccessful cartridge clamping. In such cases, it is often necessary for the operator to use a handheld blowing device to target and blow air into the clamped area while the turntable is rotating. To prevent safety hazards during rotating operation, we designed a special blowing support to fix the blowing tool to the side of the receiving belt. A compressed air pipeline switch is installed on the side of the running belt away from the rotating turntable of the loading machine. This allows the operator to quickly open the compressed air pipeline valve while observing the cartridge unclamping situation, enabling the blowing equipment to target and eliminate clamping faults. This reduces material and raw material waste caused by frequent machine starts and stops, simplifies the operation, and reduces the safety hazards of repetitive manual operations.

[0029] Both of these devices significantly improve production efficiency while reducing safety hazards for operators and greatly minimizing waste of materials, packaging film, and clipping wire during production. They also greatly assist in reducing the number of personnel operating in hazardous positions.

[0030] It will be apparent to those skilled in the art that the above specific examples are merely preferred embodiments of the present invention. Therefore, any improvements or modifications that those skilled in the art may make to certain parts of the present invention still embody the principles of the present invention and achieve the objectives of the present invention, and all fall within the scope of protection of the present invention.
