Description

Technical Field

[0001] This utility model relates to a device for cleaning floating powder during gunpowder loading, and more particularly to an automatic device for cleaning floating powder using a pressurizing punch during gunpowder loading. Background Technology

[0002] Currently, during the production of pyrotechnic products, a certain amount of floating explosive is generated on the charging punch after each loading and pressing process. Accumulated floating explosive can affect product quality and easily lead to explosions. Therefore, it is required to clean the charging punch after each loading and pressing process. Currently, the charging punch needs to be removed manually, and the punch head is thoroughly cleaned with nitrocellulose cloth soaked in alcohol before being reinstalled. Because the charging punch used in the charging assembly is quite large (50mm in diameter, 162mm in height), and made entirely of solid T10A material, each charging punch weighs approximately 10kg. During the cleaning process, the punch needs to be held in one hand while the other hand holds the nitrocellulose cloth soaked in alcohol. The cloth is used to wrap the charging end of the punch, thoroughly cleaning the bottom and sides of the punch. After cleaning, the charging punch is reinstalled. Throughout the process, if the hand is not properly held, the end of the punch covered in explosive material may fall to the ground, causing a secondary explosion. This manual operation suffers from problems such as large amounts of loose explosive material, high labor intensity, low efficiency, and poor automation. It is also greatly affected by human factors, posing certain safety hazards. Summary of the Invention

[0016] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings.

[0017] This utility model comprises five parts: a pressing and clamping mechanism for the medicine punch, a translation and lifting mechanism, a wiping mechanism for floating medicine, a waste nitrocellulose cloth collection mechanism, and a frame.

[0018] The press-type punch clamping mechanism includes a press-type punch rotary servo motor, a rotary cylinder, a gripper cylinder, and the press-type punch itself.

[0019] The translation and lifting mechanism includes a translation conveying cylinder, a servo motor for the descent depth of the press punch, a connector for the descent depth of the press punch electric cylinder, and the press punch electric cylinder for the descent depth, etc.

[0020] The drug-wiping mechanism includes an alcohol nozzle, a nitrocellulose cloth roller fixing component, nitrocellulose cloth, a drug-pressing punch fixing component, a drug-pressing punch clamping cylinder, a nitrocellulose cloth clamping cylinder, a nitrocellulose cloth clamping plate, and a nitrocellulose cloth positioning roller, etc.

[0021] The waste nitrocellulose fabric collection system includes a waste nitrocellulose fabric moving servo motor and a waste nitrocellulose fabric collection rack.

[0022] The frame includes a fixed back plate, a translation conveyor cylinder support frame, a nitrocellulose cloth support frame, and a nitrocellulose cloth roller support frame, etc.

[0023] The translational conveyor cylinder support frame is mounted on the fixed back plate. The upper left of the fixed back plate is fixed to the nitrocellulose cloth roller support frame, and the lower right is fixed to the nitrocellulose cloth bracket. The fixed back plate, translational conveyor cylinder support frame, nitrocellulose cloth bracket, and nitrocellulose cloth roller support frame constitute the main load-bearing support of the equipment. The punch is gripped by a gripper cylinder, which is fixed to a rotary cylinder. The punch rotation servo motor controls the rotary cylinder's movement. The entire mechanism is fixed to the punch descent depth electric cylinder connector, which is fixed to the translational conveyor cylinder, which is fixed by the translational conveyor cylinder support frame. After the punch is delivered from the previous process to the rightmost end of the translational conveyor cylinder, the cylinder moves the punch gripping mechanism to directly above the punch fixing component. Then, the alcohol nozzle sprays alcohol directly below the punch, thoroughly wetting the nitrocellulose cloth. After the nitrocellulose cloth is wetted, the waste nitrocellulose cloth moving servo motor rotates, moving the nitrocellulose cloth forward until it is directly below the press punch. The press punch descent depth electric cylinder connector is fixed to the press punch descent depth electric cylinder, and the press punch descent depth servo motor is also fixed thereto. The press punch descent depth servo motor controls the press punch descent depth electric cylinder to move downwards. The press punch descent depth electric cylinder drives the press punch descent depth electric cylinder connector and the press punch clamping mechanism to move downwards together. The press punch, along with the wetted nitrocellulose cloth, moves downwards and enters the press punch fixing component. The waste nitrocellulose cloth collection rack is fixed to the upper right of the fixed back plate, the nitrocellulose cloth roller fixing component is fixed to the upper left, the nitrocellulose cloth positioning roller is fixed to the lower left of the nitrocellulose cloth roller fixing component, the press punch fixing component and the press punch clamping cylinder are fixed in the middle, and the nitrocellulose cloth clamping plate clamping cylinder is fixed below the press punch clamping cylinder. After the injection punch moves to the designated position, the injection punch clamping cylinder operates, clamping both ends of the injection punch fixing component, ensuring full contact between the injection punch and the wetted nitrocellulose cloth. Simultaneously, the nitrocellulose cloth clamping cylinder on the left side of the injection punch fixing component operates, clamping the nitrocellulose cloth clamps at both ends. The waste nitrocellulose cloth moving servo motor on the right side of the injection punch fixing component actuates, tightening the nitrocellulose cloth on the right side. At this point, the nitrocellulose cloth inside the injection punch fixing component is in tight contact with the lower end and sides of the injection punch. After the above operations are completed, the injection punch rotation servo motor starts operating, controlling the rotation cylinder to rotate. The rotation cylinder drives the gripper cylinder and the injection punch it holds to rotate together. During the entire rotation process, the floating drug on the lower end and sides of the injection punch will be wiped clean by the wetted nitrocellulose cloth. After wiping clean, the nitrocellulose cloth clamping cylinder and the pressure punch clamping cylinder retract, and the pressure punch descent depth servo motor reverses, driving the pressure punch descent depth electric cylinder to move upward to the initial position. The waste nitrocellulose cloth moving servo motor activates, bringing the used waste nitrocellulose cloth to the waste nitrocellulose cloth collection rack, leaving clean nitrocellulose cloth below the alcohol nozzle.Then, the translational conveyor cylinder sends the cleaned pressing punch back to its initial position, allowing it to proceed to the next process. Example

[0024] like Figure 1As shown, the translational conveying cylinder support frame 15 is mounted on the fixed back plate 20. The nitrocellulose cloth roller support frame 6 is fixed to the upper left of the fixed back plate, and the nitrocellulose cloth bracket 22 is fixed to the lower right. The fixed back plate 20, the translational conveying cylinder support frame 15, the nitrocellulose cloth bracket 22, and the nitrocellulose cloth roller support frame 6 constitute the main load-bearing support of the equipment. The pressing punch 8 is gripped by the gripper cylinder 7, which is fixed to the rotary cylinder 5. The pressing punch rotation servo motor 3 controls the operation of the rotary cylinder 5. The entire mechanism is fixed to the pressing punch descent depth electric cylinder connector 2. The pressing punch descent depth electric cylinder 4 is fixed to the translational conveying cylinder 14, which is fixed by the translational conveying cylinder support frame 15. After the injection punch 8 is delivered from the previous process to the rightmost end of the translation conveyor cylinder 14, the translation conveyor cylinder drives the injection punch clamping mechanism (including the injection punch rotary servo motor 3, rotary cylinder 5, gripper cylinder 7, and injection punch 8) to move directly above the injection punch fixing part 17. Then, the alcohol nozzle 9 sprays alcohol onto the nitrocellulose cloth 21 directly below it, fully wetting the nitrocellulose cloth. After the nitrocellulose cloth is wetted, the waste nitrocellulose cloth moving servo motor 18 rotates, driving the nitrocellulose cloth forward, moving the wetted nitrocellulose cloth 21 directly below the injection punch 8. The injection punch descent depth electric cylinder connector 2 is fixed to the injection punch descent depth electric cylinder 4, and the injection punch descent depth servo motor 1 is fixed together with it. The servo motor controls the electric cylinder 4 of the nitrocellulose 8 to move downwards, and the electric cylinder drives the connecting part 2 and the clamping mechanism of the nitrocellulose 8 to move downwards together. During the downward movement, the nitrocellulose 8 first touches the wetted nitrocellulose cloth 21. The wetted nitrocellulose cloth is subjected to the downward force given by the nitrocellulose 8, and the nitrocellulose 8 will drive the wetted nitrocellulose cloth to move downwards together and enter the nitrocellulose 8 fixing part 17. Due to the movement of the wetted nitrocellulose cloth 21, the nitrocellulose cloth positioning roller 13 will roll. A waste nitrocellulose cloth collection rack 19 is fixed to the upper right of the fixed back plate 20, a nitrocellulose cloth support 22 is fixed to the lower right, a nitrocellulose cloth roller fixing component 10 is fixed to the upper left, and a nitrocellulose cloth positioning roller 13 is fixed to the lower left of the nitrocellulose cloth roller fixing component. A pressing punch fixing component 17 and a matching pressing punch clamping cylinder 16 are fixed at a suitable position in the middle. A nitrocellulose cloth clamping plate clamping cylinder 12 is fixed at a suitable position below the pressing punch clamping cylinder. Then, the nitrocellulose cloth positioning roller 13 is added in the remaining space to allow the nitrocellulose cloth to move smoothly back and forth without jamming. After the pressing punch 8 moves to the designated position, the pressing punch clamping cylinder 16 operates, clamping the left and right ends of the pressing punch fixing component 17, ensuring full contact between the pressing punch 8 and the wetted nitrocellulose cloth 21.Simultaneously, the nitrocellulose cloth clamping cylinder 12, located on the left side of the press punch fixing component 17, operates, clamping the nitrocellulose cloth clamping plates 11 at both ends. Meanwhile, the waste nitrocellulose cloth moving servo motor 18, located on the right side of the press punch fixing component 17, actuates, pulling the nitrocellulose cloth 21 on the right side taut. At this point, the nitrocellulose cloth 21 inside the press punch fixing component 17 will be in tight contact with the lower end and sides of the press punch 8. After the above operations are completed, the press punch rotation servo motor 3 starts operating, controlling the rotation cylinder 5 to rotate. The rotation cylinder drives the gripper cylinder 7 and the press punch 8 it grips to rotate together. During the entire rotation process, the floating medicine on the lower end and sides of the press punch 8 will be wiped clean by the wetted nitrocellulose cloth 21. After wiping clean, the nitrocellulose cloth clamping cylinder 12 and the pressure punch clamping cylinder 16 retract, and the pressure punch descent depth servo motor 1 reverses, driving the pressure punch descent depth electric cylinder 4 to move upward to the initial position. The waste nitrocellulose cloth moving servo motor 18 activates, bringing the used waste nitrocellulose cloth to the waste nitrocellulose cloth collection rack 19, leaving the clean nitrocellulose cloth 21 below the alcohol nozzle 9. Then, the translation conveying cylinder 14 sends the wiped-clean pressure punch 8 back to the initial position, proceeding to the next process.

[0025] Operation of the device and the gunpowder loading assembly:

[0026] This utility model device is located in the middle of the production line. After the product is pressed, the pressing punch 8 is sent from the previous process to the rightmost end of the translation conveyor cylinder 14. The translation conveyor cylinder drives the pressing punch clamping mechanism to move horizontally above the pressing punch fixing part 17. Then, the alcohol nozzle 9 sprays alcohol directly below the nitrocellulose cloth 21, fully wetting the nitrocellulose cloth. After the nitrocellulose cloth 21 is wetted, the waste nitrocellulose cloth moving servo motor 18 rotates, driving the nitrocellulose cloth forward, moving the wetted nitrocellulose cloth directly below the pressing punch. Then, the pressing punch descent depth servo motor 1 controls the pressing punch descent depth electric cylinder 4 to move downward. The pressing punch descent depth electric cylinder 4 drives the pressing punch descent depth electric cylinder connecting part 2 and the pressing punch clamping mechanism to move downward together. During its downward movement, the punch 8 first contacts the wetted nitrocellulose cloth 21. The wetted nitrocellulose cloth 21, subjected to a downward force from the punch 8, moves downwards along with the punch, entering the punch holder 17. Due to the movement of the wetted nitrocellulose cloth 21, the nitrocellulose cloth positioning roller 13 rolls. Once the punch 8 has reached the designated position, the punch clamping cylinder 16 operates, clamping both ends of the punch holder 17, ensuring full contact between the punch 8 and the wetted nitrocellulose cloth. Simultaneously, the nitrocellulose cloth clamping cylinder 12 on the left side of the press punch fixing component 17 operates, clamping the nitrocellulose cloth clamping plates 11 at both ends. The waste nitrocellulose cloth moving servo motor on the right side of the press punch fixing component actuates, tightening the nitrocellulose cloth on the right side. At this point, the nitrocellulose cloth inside the press punch fixing component 17 will be in tight contact with the lower end and sides of the press punch 8. After the above operations are completed, the press punch 8 rotation servo motor starts working, controlling the rotation cylinder 5 to rotate. The rotation cylinder drives the gripper cylinder 7 and the press punch 8 it grips to rotate together. During the entire rotation process, the floating medicine on the lower end and sides of the press punch will be wiped clean by the wetted nitrocellulose cloth 21. After wiping clean, the nitrocellulose cloth clamping cylinder 12 and the press punch clamping cylinder 16 retract, and the press punch descent depth servo motor 1 begins to reverse, driving the press punch descent depth electric cylinder 4 to move upward to the initial position. The waste nitrocellulose cloth moving servo motor 18 moves to bring the used waste nitrocellulose cloth to the waste nitrocellulose cloth collection rack 19, leaving the clean nitrocellulose cloth 21 below the alcohol nozzle 9; then the translational conveying cylinder 14 sends the wiped-cleaned pressing punch 8 back to the initial position, and enters the next process.
