Description

Technical Field

[0001] This utility model relates to a device for producing pyrotechnic products, and more particularly to a split-type sealed negative pressure device for producing detonators. Background Technology

[0002] Delay detonators are one of the important components of pyrotechnics. During the assembly of delay detonators, after the delay tube is pushed into the detonator, a ring-making tool is used to make a ring-making process on the top of the detonator output end. After the ring-making process, shellac paint needs to be manually applied to the ring-making area of ​​the detonator.

[0003] During the ring-binding process, air can enter the detonator body. After the detonator body is manually coated with glue, the presence of air inside the detonator body will cause air bubbles to form on the surface of the glued area. To avoid product quality problems, the air bubbles need to be popped manually, which is very labor-intensive and time-consuming. Summary of the Invention

[0004] The purpose of this utility model is to provide a split-type sealing negative pressure device for the production of pyrotechnic detonators. The device adopts a split-type negative pressure mechanism, and a sealing ring is installed at the bottom of the fixture plate to ensure that the negative pressure chamber inside the mechanism is completely sealed when vacuuming, so as to avoid air leakage; thus ensuring the production quality and assembly efficiency of pyrotechnic detonators.

[0005] The objective of this utility model is achieved through the following technical solution: A split-type sealed negative pressure extraction device for the production of detonators, comprising four split negative pressure extraction mechanisms connected together by a fixed plate. An inlet / outlet valve is installed on the right side of the negative pressure extraction chamber. A fixed plate is installed at the upper end of the negative pressure extraction chamber. Four telescopic rods are installed at the four corners of the top of the fixed plate, secured by fixed sleeves. A connecting plate is installed at the top of every two telescopic rods. A bolt connects to the middle of the top of the fixed plate, connecting to an explosion-proof cylinder. An electronic pressure gauge is mounted on the connecting plate of the negative pressure extraction mechanism. Small bolts are installed on both sides above the fixture plate base. An inlet / outlet cylinder module is installed in the middle of the top of the fixture plate base. A fixture plate placement plate is connected to the fixture plate base by small bolts. A sealing ring is installed around the perimeter of the fixture plate placement plate, and four fixture plate supports are installed inside the sealing rings and on the fixture plate placement plate.

[0006] The aforementioned split-type sealed negative pressure extraction device for the production of pyrotechnic detonators includes an explosion-proof cylinder, a telescopic rod connecting plate, a telescopic rod, a negative pressure extraction mechanism connecting and fixing plate, a negative pressure extraction mechanism connecting and fixing plate bracket, a fixing sleeve, bolts, a negative pressure extraction chamber fixing plate, a negative pressure extraction chamber, a fixture plate placement plate, small bolts, a fixture plate fixing base, and a negative pressure extraction mechanism connecting and fixing plate bracket base.

[0007] The aforementioned split-type sealed negative pressure extraction device for the production of pyrotechnic detonators includes an explosion-proof cylinder that passes through a negative pressure extraction mechanism connecting and fixing plate. The lower end of the explosion-proof cylinder is connected to a bolt, which is connected to the upper end of a connecting sleeve. The lower end of the connecting sleeve and the negative pressure extraction chamber fixing plate are connected by bolts, and a negative pressure extraction chamber is installed below the negative pressure extraction chamber fixing plate.

[0008] The aforementioned split-type sealed negative pressure extraction device for the production of pyrotechnic detonators includes telescopic rods installed at the four corners of the upper end of the fixed plate of the negative pressure extraction chamber. The telescopic rods are fixed by connecting sleeves, pass through the negative pressure extraction mechanism connecting fixed plate, and are connected to the upper end of the telescopic rods by a telescopic rod connecting plate.

[0009] The advantages and effects of this utility model are: 1. This utility model solves the problem of air bubbles forming on the surface after adhesive application due to air in the detonator body. It adopts a split-type negative pressure suction mechanism, with a sealing ring installed at the bottom of the fixture plate to ensure that the negative pressure chamber inside the mechanism is completely sealed during vacuuming, preventing air leakage. An electronic pressure gauge is designed above the negative pressure suction mechanism to display the current pressure in the negative pressure chamber in real time. When the pressure reaches the set standard value, the negative pressure chamber is raised. The four split-type negative pressure suction mechanisms are connected by a negative pressure suction mechanism connecting plate. The four split-type negative pressure suction mechanisms can be lowered sequentially to extract negative pressure for multi-mode products, ensuring production and assembly efficiency.

[0010] 2. In the detonator assembly and production process, this utility model device sequentially and fully extracts the air from the multi-mode detonator and ensures that the pressure in the chamber of the negative pressure extraction mechanism reaches the set value, thus avoiding the problem of air bubbles at the glue application point in the subsequent glue application process. This saves a lot of manpower and time, and improves production efficiency and product yield. Attached Figure Description

[0013] The present invention will now be described in further detail with reference to the accompanying drawings.

[0014] A detonator split-type sealing negative pressure extraction device is designed inside an explosion-proof steel plate. The device consists of four split negative pressure extraction mechanisms connected together by a fixed plate. The mechanisms move downwards in sequence to complete the negative pressure extraction of multi-mode products, ensuring safe production and efficient and high-quality assembly of detonator products.

[0015] Split-type negative pressure extraction mechanism, such as Figure 1 As shown, it consists of an explosion-proof cylinder 1, a telescopic rod connecting plate 2, a telescopic rod 3, a negative pressure suction mechanism connecting and fixing plate 4, a fixing sleeve 6, a bolt 7, a connecting sleeve 8, a negative pressure suction chamber fixing plate 9, a negative pressure suction chamber 10, a fixture tray placement plate 11, a small bolt 12, a fixture tray fixing base 13, an inlet / outlet valve 15, a sealing ring 16, a fixture tray bracket 17, an inlet / outlet cylinder module 18, and an electronic pressure gauge 19.

[0016] An inlet / outlet valve 15 is installed on the right side of the negative pressure chamber 10. A negative pressure chamber fixing plate 9 is installed on the upper end of the negative pressure chamber 10. Four telescopic rods 3 are installed at the four corners of the top of the negative pressure chamber fixing plate 9. All telescopic rods 3 are fixed by fixing sleeves 6. A telescopic rod connecting plate 2 is installed at the top of every two telescopic rods 3. A bolt 7 is connected at the middle of the top of the negative pressure chamber fixing plate 9. The bolt 7 is connected to the explosion-proof cylinder 1. An electronic pressure gauge 19 is installed on the negative pressure mechanism connecting fixing plate 4. Small bolts 12 are installed on both sides above the fixture plate fixing base 13. An inlet / outlet cylinder module 18 is installed at the middle of the top of the fixture plate fixing base 13. The fixture plate placement plate 11 is connected to the fixture plate fixing base 13 by small bolts 12. A sealing ring 16 is installed around the fixture plate placement plate 11. Four fixture plate brackets 17 are installed inside the sealing ring 16 and on the fixture plate placement plate 11.

[0017] Detonator split-type sealed negative pressure device, such as Figure 1 As shown, it consists of an explosion-proof cylinder 1, a telescopic rod connecting plate 2, a telescopic rod 3, a negative pressure extraction mechanism connecting and fixing plate 4, a negative pressure extraction mechanism connecting and fixing plate bracket 5, a fixing sleeve 6, bolts 7, a negative pressure extraction chamber fixing plate 9, a negative pressure extraction chamber 10, a fixture tray placement plate 11, small bolts 12, a fixture tray fixing base 13, and a negative pressure extraction mechanism connecting and fixing plate bracket base 14.

[0018] An explosion-proof cylinder 1 passes through a negative pressure suction mechanism connecting plate 4. A bolt 7 is connected to the lower end of the explosion-proof cylinder 1, and the bolt 7 is connected to the upper end of a connecting sleeve 8. The lower end of the connecting sleeve 8 is connected to a negative pressure suction chamber fixing plate 9 via bolt 7. A negative pressure suction chamber 10 is installed below the negative pressure suction chamber fixing plate 9. Telescopic rods 3 are installed at the four corners of the upper end of the negative pressure suction chamber fixing plate 9. The telescopic rods 3 are fixed by fixing sleeves 6, and pass through the negative pressure suction mechanism connecting plate 4. The upper end of the telescopic rods 3 is connected by a telescopic rod connecting plate 2. Example

[0019] like Figure 1As shown, the explosion-proof cylinder 1 in the split negative pressure suction mechanism passes through the center of the negative pressure suction mechanism connecting plate 4. The lower end of the explosion-proof cylinder 1 is connected to the center of the negative pressure suction chamber fixing plate 9 through bolts 7 and fixing sleeves 8. The negative pressure suction chamber fixing plate 9 is installed on the top of the negative pressure suction chamber 10. To further fix the negative pressure suction chamber 10, telescopic rods 3 are installed at the four corners of the top of the negative pressure suction chamber fixing plate 9. The telescopic rods 3 pass through the negative pressure suction mechanism connecting plate 4. The fixing sleeves 6 are installed below the negative pressure suction mechanism connecting plate 4. At the same time, the fixing sleeves 6 are nested outside the telescopic rods 3 to fix the telescopic rods 3. To further reinforce the telescopic rods 3, every two telescopic rods 3 are connected by a telescopic rod connecting plate 2.

[0020] The jig tray fixing base 13 has an infeed / discharge cylinder module 18 installed in the middle. The jig tray fixing base has small bolts 12 at the dead corners to fix the jig tray placement plate 11. Sealing rings 16 are installed around the jig tray placement plate 11, and a sealing ring 16 is installed at the center of the jig tray placement plate 11. The material tray moves through the feed cylinder module 18 and reaches the fixture tray support 17. After the material tray is in place, the explosion-proof cylinder 1 moves downward. Driven by the explosion-proof cylinder 1, the negative pressure chamber 10 moves downward at the same time. The telescopic rod 3 moves downward at the same time under the action of the negative pressure chamber 10. After the explosion-proof cylinder 1 reaches the lower limit, the explosion-proof cylinder 1 stops moving downward. At the same time, the negative pressure chamber 10 reaches the standard position and stops moving.

[0021] When the negative pressure chamber 10 is in position, it covers the fixture tray placement plate 11. The sealing rings 16 installed around the fixture tray placement plate 11 ensure that the entire chamber is completely sealed after the negative pressure chamber 10 is lowered. After the negative pressure chamber 10 is in position, the inlet / outlet valve 15 starts to evacuate the chamber. An electronic pressure gauge 19 is installed above the negative pressure mechanism connecting fixing plate 4. The electronic pressure gauge 19 displays the pressure reading in the chamber in real time. When the set pressure value is reached, the inlet / outlet valve 15 in the mechanism stops evacuating. The negative pressure chamber 10 is lifted by the explosion-proof cylinder 1, and the telescopic rod 3 is lifted by the action of the negative pressure chamber 10. After the negative pressure chamber 10 is lifted back to its original position, the feed / discharge cylinder module 18 is activated to push out the material tray.

[0022] like Figure 2As shown, the detonator split-type sealed negative pressure device consists of four split negative pressure extraction mechanisms. The explosion-proof cylinders 1 of the four negative pressure extraction mechanisms are installed sequentially from right to left on the negative pressure extraction mechanism connecting and fixing plate 4. A negative pressure extraction mechanism connecting and fixing plate bracket 5 is installed at each of the four corners of the negative pressure extraction mechanism connecting plate 4, and two negative pressure extraction mechanism connecting and fixing plate brackets 5 are installed at the center line of the negative pressure extraction mechanism connecting plate 4, serving to fix the device. The negative pressure extraction mechanism connecting and fixing plate brackets 5 are installed on the negative pressure extraction mechanism connecting and fixing plate bracket base 14. Four electronic pressure gauges 19 are fixed next to the four explosion-proof cylinders 1 on the negative pressure extraction mechanism connecting and fixing plate 4. After the device is started, the four material trays are manually placed at the equipment inlet. The rightmost material tray first enters the fixture tray placement plate 11 through the inlet / outlet cylinder module 18. The negative pressure extraction chamber 10 descends, covering the fixture tray placement plate 11. Then, the inlet / outlet valve 15 begins to extract pressure, and simultaneously, the electronic pressure gauge 19 displays the pressure reading in the chamber in real time. The second negative pressure suction mechanism from right to left starts operating, and its operation mode is the same as that of the rightmost negative pressure suction mechanism. After the inlet / outlet valve 15 of the second negative pressure suction mechanism starts suction, the third negative pressure suction mechanism from right to left starts operating. After the inlet / outlet valve 15 of this mechanism starts suction, the rightmost negative pressure suction mechanism starts operating. The internal pressure of each mechanism is set to 95 MPa. When the electronic pressure gauge 19 reads 95, the inlet / outlet valve 15 stops suction and maintains this position for one minute. Finally, the four explosion-proof cylinders rise sequentially, and the four negative pressure suction chambers 10 are raised sequentially from right to left. After the negative pressure suction chamber 10 is raised to its position, the four feed / discharge cylinder modules 18 sequentially push the material tray to the discharge port.
