Description

Technical Field

[0001] This invention belongs to the field of nail gun cartridge production technology, specifically relating to an automatic propellant application machine. Background Technology

[0002] Before the propellant is spun, it needs to be metered to form a measured amount of pellets. Currently, this is done manually by applying it to a metering plate. However, as the base propellant for nail gun cartridges, the propellant is quite sensitive and easily flammable. Although some water is added during application to reduce the risk of spontaneous combustion, the moisture content of the propellant needs to be controlled within a certain range. Therefore, manual application still carries certain risks. Summary of the Invention

[0003] This invention aims to provide an automatic powder application machine for firing, which can automatically apply the powder, thereby reducing the safety threats to workers.

[0004] Therefore, the technical solution adopted by the present invention is as follows: an automatic drug-applying machine for firing propellants, including a worktable and a drug-filling box for holding firing propellants.

Detailed Implementation

[0046] The present invention will be further described below with reference to the embodiments and accompanying drawings: like Figure 1-26As shown, an automatic powder-applying machine is installed in an explosion-proof room to reduce worker injuries. The machine is used to fill the metering plate 1 with powder. A conveyor line is used to move the metering plate 1 inside and outside the explosion-proof room, and the conveyor line A extends to the left and right through the powder-applying machine B.

[0047] The application machine mainly consists of a workbench 2, a support frame 4, an application base plate 6, a medicine box tray moving assembly, an application assembly, and an application lifting assembly. It is also equipped with a medicine box 3, which has a through-type structure for loading the firing powder, and a medicine box base 5. The workbench 2 is positioned above conveyor line A via the support frame 4. The workbench 2 has an application base plate 6 for applying the powder. To facilitate application, an application groove 6a is provided on the rear side of the application base plate 6, exposing the powder loading portion of the metering plate. The application base plate 6 has an application assembly and a medicine box tray moving assembly for moving the medicine box and medicine box base closer to the application groove. For easy handling of the medicine box, the application assembly is located behind the medicine box tray moving assembly. The support frame 4 contains an application lifting assembly for lifting the metering plate located on the conveyor line to the application groove. When the medicine box 3 with the medicine box base 5 is placed on the medicine box tray moving assembly, the bottom of the medicine box 3 is flush with the top of the metering plate 1 after being lifted by the medicine application lifting assembly.

[0048] The medicine box tray moving assembly includes a medicine box base moving frame 8 that can move back and forth under the action of a first moving component 7, and the first moving component 7 is disposed on the medicine application base plate 6. To prevent the medicine box base from moving, a medicine box base positioning pin 8a is provided on the medicine box base moving frame 8, and a medicine box base positioning hole 5a is provided on the medicine box base 5 for inserting the corresponding medicine box base positioning pin 8a, and the medicine box base positioning hole 5a is disposed on the fixed flange 5b at the lower end of the medicine box base 5. When placing a medicine box base containing medicine boxes, the medicine box base positioning hole is aligned with the medicine box base positioning pin for insertion.

[0049] The medication application assembly includes clamping components for clamping the medication box 3, which are arranged opposite each other on the left and right sides. Both clamping components are mounted on the medication application plate 9. A slot 9a is provided on the front side of the medication application plate 9 for the medication box 3 to be inserted into, and the medication application plate 9 can move back and forth under the action of the second moving component 10. In order to fix the medication box so that it can move with the medication application moving component, a positioning flange 3a is provided at the upper end of the medication box 3, and the height of the positioning flange 3a is higher than the height of the medication box base 5. On the medication application plate 9, on the left and right inner sides of the slot 9a, there are lower limit blocks 9b that can be inserted between the positioning flange 3a and the medication box base 5 and are used to prevent the medication box 3 from falling downward after leaving the medication box base 5. The top surface of the lower limit block 9b is flush with the bottom surface of the positioning flange 3a of the medication box 3 placed on the medication box base moving component.

[0050] The clamping assembly includes a positioning cylinder 12 mounted on the medicine application plate 9 via a positioning seat 11. A positioning moving plate 13 is mounted on the output shaft of the positioning cylinder 12, and a medicine box positioning pin 14 is mounted on the positioning moving plate 13. A medicine box positioning hole 3b for inserting the medicine box positioning pin 14 is provided on the corresponding positioning flange 3a. An upper limit block 15 is positioned on the medicine application plate 9, positioned above the lower limit block 9b, and the upper limit block 15 is provided with a positioning through groove 15a for the medicine box positioning pin 14 to pass through. The height between the lower limit block 9b and the upper limit block 15 matches the thickness of the positioning flange 3a. To facilitate the movement of the positioning flange of the medicine box between the upper and lower limit blocks, guide slopes are provided at the front ends of both the lower limit block 9b and the upper limit block 15 to facilitate engagement with the positioning flange 3a. Before applying the medicine, the medicine box is moved to the medicine application preparation position by the medicine box tray moving assembly. At this time, the positioning flange is located between the upper limit block and the lower limit block. Then, the positioning cylinder works to insert the medicine box positioning pin into the corresponding medicine box positioning hole. When applying the medicine, the second moving assembly drives the medicine application plate to move, thereby realizing the separation of the medicine box and the medicine box tray.

[0051] A compression assembly is provided on the smearing plate 9 to ensure that the propellant in the propellant box 3 falls smoothly. The compression assembly includes a compression cylinder 17 mounted on the smearing plate 9 via a compression seat 16. A compression plate 18 is provided at the output end of the compression cylinder 17, which can extend into the propellant box 3. The cross-section of the compression plate 18 matches the cross-section of the propellant-filling part of the propellant box 3, so that the compression plate can extend into the propellant box and push the propellant to move downward.

[0052] The application lifting assembly includes a lifting base plate 20 mounted within the support frame 4 via a third moving component 19. The third moving component 19 can move the lifting base plate 20 back and forth. An application lifting cylinder 21 is mounted on the lifting base plate 20. An application lifting plate 22 is mounted at the output end of the application lifting cylinder 21. A permanent magnet platform 23 is mounted on the application lifting plate 22 to prevent the metering plate 1 from moving. A switching component for switching the magnetism of the permanent magnet platform 23 is equipped on the permanent magnet platform 23. A water-absorbing component is also mounted on the permanent magnet platform 23. Because the entire application machine is located in an explosion-proof chamber, electromagnets cannot be used. The function of the third moving component is to push the application lifting assembly to the front, facilitating the replacement of the water-absorbing component.

[0053] The switching assembly includes a switching cylinder 24 mounted on a permanent magnet platform 23. The output end of the switching cylinder 24 has a left-right extending switching rack 25. The permanent magnet platform 23 includes a permanent magnet housing and a permanent magnet. The permanent magnet is mounted inside the permanent magnet housing via a switching shaft, which can rotate relative to the permanent magnet housing. One end of the switching shaft passes through the permanent magnet housing and has a switching gear 26 that meshes with the switching rack 25. The switching gear 26 and the switching rack 25 are covered by a waterproof protective cover 27. When the switching cylinder operates, the switching rack and the switching gear work together to rotate the switching shaft, thereby changing the direction of the polarity of the permanent magnet, allowing the permanent magnet platform to be attached to the bottom surface of the metering plate as needed.

[0054] The water absorption assembly includes a water absorption belt 28 extending laterally on the permanent magnet platform 23. Support rollers 29 are located on both sides of the permanent magnet platform 23 to maintain the state of the water absorption belt 28. Support roller brackets 30 on the front and rear sides of the support rollers 29 are mounted on the permanent magnet platform 23. To reduce the frequency of water absorption assembly replacement, a mounting plate 32 is installed below the medicine application lifting plate 22 via a connecting column 31. A water absorption belt replacement assembly for automatic replacement of the water absorption belt 28 is installed on the mounting plate 32. A guide rod 33 is installed between the mounting plate 32 and the lifting base plate 20.

[0055] The suction belt replacement assembly includes a suction belt drive roller 34 and a suction belt driven roller 35 spaced apart on the mounting plate 32. The rear sides of both the drive roller 34 and the driven roller 35 are rotatably mounted on a mounting bracket 36. Each of the drive roller 34 and the driven roller 35 has a mounting plate 37 spaced apart for fixing the corresponding suction belt cylinder. The drive roller 34 is equipped with a rotary cylinder 38 for rotation. When replacing the suction belt cylinder, the third moving assembly moves the entire application lifting assembly forward, the front mounting plate is removed, the suction belt cylinder is taken out, a new one is replaced, and the front mounting plate is installed.

[0056] Since the ignition agent used for applying the medicine contains moisture, a groove 2a for collecting the liquid is provided on the workbench 2 to facilitate the collection of water flowing out during application. A water-collecting hole 2b is also provided on the groove 2a, communicating with a movable component located outside the workbench 2. The first, second, and third moving components have similar structures, each including a moving cylinder mounted at a corresponding position via a corresponding moving cylinder bracket and a guide component to ensure linear movement. The first moving component has two moving cylinders spaced apart on the left and right sides, and the moving cylinders of the first and second moving components are mounted on the application base plate via corresponding moving cylinder brackets. The moving cylinder of the third moving component is mounted on a support frame via a corresponding moving cylinder bracket. The guide components of the first, second, and third moving components all use guide rail slider assemblies, and the first and second moving components share a common guide rail.

[0057] A receiving assembly is provided between the drug-applying base plate 6 and the workbench 2 to collect the explosive charge that falls from the drug container 3 as it moves back and forth on the drug container base 5. Correspondingly, a receiving slot 6b is provided at the front end of the drug-applying base plate 6 for easy receiving of the explosive charge. The receiving assembly includes a receiving cylinder 39 located at the front end of the workbench 2 and a receiving base 40 located below the front end of the drug-applying base plate 6. A U-shaped receiving moving block 41 is provided at the output end of the receiving cylinder 39, and a mounting part 40a is provided at the front end of the receiving base 40 to facilitate the insertion of the rear end of the receiving moving block. During receiving, the receiving base is pushed forward, making the receiving base and the receiving moving block detachably mounted.

[0058] To prevent interference between the receiving base and the metering plate after lifting, support protrusions 2c are provided on the left, right and rear sides of the front end of the workbench 2 to support the medicine application base. The support protrusions 2c on the left and right sides are provided with limiting grooves 2d in the middle. Correspondingly, limiting flanges 40b that can move back and forth in the limiting grooves 2d are provided on the left and right sides of the receiving base 40.

[0059] To facilitate the removal of the firing propellant from the receiving tray, a propellant-flipping assembly is provided on the left side of the support frame 4 to rotate the propellant-applying base plate 6 for collecting the floating propellant on the receiving tray. The propellant-flipping assembly includes a propellant-flipping cylinder 43 mounted on the support frame 4 via a propellant-flipping seat 42. The output end of the propellant-flipping cylinder 43 is hinged to the bottom left side of the propellant-applying base plate 6. Both front ends of the left side of the propellant-applying base plate 6 are hinged to the worktable. A detachable fixing assembly is also provided between the propellant-applying base plate and the worktable to prevent accidental operation of the propellant-flipping cylinder.

[0060] At least two detachable fixing components are provided at a distance from front to back on the right side of the application base plate 6. Each detachable fixing component includes a hinge shaft 44 with one end hinged to the worktable. An opening slot 6c is provided on the side of the application base plate 6 corresponding to the hinge shaft 44. The other end of the hinge shaft 44 is rotatably engaged into the opening slot 6c and then pressed by a fixing nut 45. The fixing nut is a wing nut or other nut that is easy to rotate. During application of the medicine, the hinge shaft is fixed by the fixing nut to prevent the application base plate from flipping. When collecting the firing powder in the receiving tray, the fixing nut is removed, and then the application flipping cylinder operates, causing the right side of the application base plate to flip upward, thereby facilitating the removal of the receiving tray.

[0061] To ensure that the metering plate moving on the conveyor line accurately stops on the application machine, an application blocking assembly is installed on conveyor line A for each application machine B to restrict the movement of the metering plate. The application blocking assembly includes an application blocking cylinder 48 installed on the conveyor line and an application blocking block 49 with a U-shaped cross-section installed at the output end of the cylinder 48. Both ends of the application blocking block 49 face the application machine, and both ends of the block have blocking flanges 49a located on the front and rear sides of the absorbent belt. When the cylinder operates, the application blocking block moves upward, causing the blocking flanges to press against the right side of the metering plate, thus stopping the metering plate at the corresponding position on the application machine.

[0062] To ensure the proper front-to-back position of the metering plate and align the metering holes on it with the application groove, front and rear limiting components are installed opposite each other on the conveyor line. These components include front and rear limiting cylinders 71 mounted on the conveyor line, and front and rear limiting blocks 72 mounted on the output ends of the cylinders. When the metering plate stops under the action of the application blocking components, the two front and rear limiting cylinders operate simultaneously, pushing the metering plate back and forth via the limiting blocks, thereby adjusting the front-to-back position of the metering plate.

[0063] The application process is as follows: 1. Loading the explosive. The operator first places the explosive box on the bottom tray, then loads the explosive into the explosive box, and then enters the explosion-proof chamber to place the bottom tray on the bottom tray moving frame, ensuring that the bottom tray positioning pin is inserted into the bottom tray positioning hole, and then leaves the explosion-proof chamber.

[0064] 2. Preparation of the medicine box for firing. The first moving component moves the medicine box base to the medicine preparation position and positions the positioning flange between the upper and lower limit blocks. Then, the positioning cylinder operates to insert the medicine box positioning pin into the corresponding medicine box positioning hole.

[0065] 3. Metering Plate Preparation. The application blocking component stops the metering plate moving on the conveyor line at the application machine position. Then, the front and rear limit components work to adjust the front and rear positions of the metering plate. Next, the switching component puts the permanent magnet platform in a state where it can be attracted to the metering plate. Then, the application lifting cylinder works to drive the permanent magnet platform upward. During the rope lifting process, the metering plate is first attracted to the permanent magnet platform, and then it rises together with the metering plate. After the top surface of the metering plate contacts the ground of the application base plate, the movement stops.

[0066] 4. Applying the powder. The powder-applying cylinder operates, causing the powder container to detach from the base. Once the powder container is separated from the base, the squeezing cylinder operates, causing the squeezing plate to extend into the powder container and push the powder downwards. Through the back-and-forth operation of the powder-applying cylinder and the downward movement of the squeezing plate, the powder is applied into the metering holes of the metering plate.

[0067] 5. Return to Position. After the medication is applied, the squeezing cylinder and the medication application cylinder stop working. Then, the medication application cylinder works to push the medication box to the bottom tray. Simultaneously, the metering plate moves downward under the action of the medication application lifting cylinder. When the metering plate is about to land on the conveyor line, the switching component changes the polarity of the permanent magnet platform, preventing it from adhering to the metering plate. This allows the metering plate to land on the conveyor line and separate from the permanent magnet platform. Then, the medication application blocking cylinder returns to its position, allowing the metering plate to move along the conveyor line. Alternatively, when the metering plate lands on the conveyor line, the medication application lifting cylinder stops working first, then the polarity of the permanent magnet platform is switched, and the medication application lifting cylinder works again to drive the permanent magnet platform back to its original position. After the metering plate separates from the permanent magnet platform, the rotary cylinder works to replace the absorbent belt located on the permanent magnet platform.

[0068] To reduce the amount of powder floating on the metering plate after application, a metering plate flipping device C is installed on the right side of the powder application machine B on conveyor line A to flip the metering plate 1. To ensure the amount of powder fired in each metering hole on the metering plate, powder application machines B and metering plate flipping devices C are also installed on conveyor line A at intervals to the left and right of the metering plate flipping device C.

[0069] The metering plate flipping device includes a fixed collection box 54 set below the conveyor line A via a metering plate flipping seat 53. The bottom of the fixed collection box 54 is set as a collection slope 54a that slopes forward and downward. A collection conduit 54b for communicating with a movable collection box is set at the front end of the collection slope 54a. At the same time, a metering plate flipping assembly for flipping the metering plate 1, a flipping push-in assembly for pushing the metering plate 1 into the metering plate flipping assembly, and a flipping push-out assembly for pushing the metering plate 1 out of the metering plate flipping assembly are also set on the metering plate flipping seat 53.

[0070] The metering plate flipping assembly includes a flipping plate 55 and two support seats 56 spaced apart on a metering plate flipping base 53. A flipping shaft 55a is provided at the rear end of the flipping plate 55 and is rotatably mounted on the support seat 56. Metering plate grooves 55b are provided on the left and right sides of the middle of the flipping plate 55 for the metering plate 1 to be inserted from front to back, and the center of the metering plate grooves 55b is at the same height as the center of the flipping shaft 55a. Floating drug channels 55c are provided at the upper and lower ends of the flipping plate 55 for the floating drug located on the metering plate 1 to fall. Weight-reducing grooves 55d are provided on the front and left and right sides of the flipping plate 55 to reduce weight. To achieve the flipping of the flipping shaft, a flipping gear 57 is sleeved on the flipping shaft 55a. A vertically extending flipping rack 58 is provided on either the left or right side of the flipping gear 57, and the flipping rack 58 is driven to move up and down by a metering plate flipping cylinder 59. Preferably, rollers are provided on both the upper and lower sides of the metering plate groove 55b to facilitate the movement of the metering plate.

[0071] The flip-out assembly includes a flip-out cylinder 60 disposed within the flip shaft 55a, and a flip-out block 61 is disposed at the output end of the flip-out cylinder 60 after passing through the flip plate 55.

[0072] The flip-and-push assembly includes a flip-and-push cylinder 63, which is mounted on conveyor line A via a flip-and-push bracket 62 and extends forward and backward. A metering plate pushing-limiting cylinder 64 is mounted on the output block of the flip-and-push cylinder 63, and a metering pushing-limiting plate 65, capable of extending below the metering plate 1, is mounted on the output end of the metering plate pushing-limiting cylinder 64. To ensure the metering plate accurately enters the metering plate slot, a metering clamping-limiting cylinder 66 is mounted at the rear end of the flip-and-push bracket 62 to prevent the front end of the metering plate 1 from tilting upward during pushing. A metering clamping-limiting block 67, capable of pressing against the metering plate 1, is mounted on the output end of the metering clamping-limiting cylinder 66, and a scraper portion 67a for scraping the floating medicine on the metering plate is mounted at the lower end of the metering clamping-limiting block 67.

[0073] To ensure the metering plate accurately stops on the metering plate flipping device, a flipping blocking assembly is installed on conveyor line A for each metering plate flipping device C to restrict the movement of the metering plate. The flipping blocking assembly includes a flipping blocking cylinder 46 mounted on conveyor line A via a corresponding bracket and an L-shaped flipping blocking block 47 located at the output end of the flipping blocking cylinder 46. The flipping blocking cylinder can stop the metering plate after the medication application is completed at the corresponding position of the metering plate flipping assembly.

[0074] To ensure the metering plate can be flipped within the flipping device, a flipping and lifting assembly is installed on conveyor line A at the position corresponding to the metering plate flipping device to push the metering plate out of the conveyor line. The flipping and lifting assembly includes a flipping and lifting cylinder installed on conveyor line A, a flipping and lifting plate at the output end of the cylinder, and height limiting blocks 52 on both sides of conveyor line A at the positions of the metering plate flipping device C. The height limiting blocks are configured with a "7"-shaped structure, and a guide limiting groove 52a is provided on the side of the height limiting block 52 facing the metering plate flipping device. When the metering plate stops at the corresponding position, the flipping and lifting cylinder operates, pushing the metering plate upwards via the flipping and lifting plate. Due to the presence of the height limiting blocks, not only is the lateral position of the metering plate limited, but also its lifting height.

[0075] In this embodiment, two metering plate flipping devices are located, one at the front of the conveyor line and the other at the rear, as needed, but the movable collection box must be located at the front. Because there are two metering plate flipping devices, each device can flip its corresponding metering plate only once during the flipping process.

[0076] Taking the metering plate flipping device located at the rear of the conveyor line as an example, its flipping process is as follows: 1. Preparation for flipping. Under the action of the flipping blocking component, the metering plate after the medicine has been applied is stopped on the metering plate flipping device. Then the flipping lifting component works to lift the metering plate upward.

[0077] 2. Metering Plate Push-In. The metering plate pushing-in limiting cylinder and the tilting and moving cylinder operate, causing the metering pushing-in limiting plate to extend below the lifted metering plate. Then, the metering plate pushing-in limiting cylinder and the metering pressing limiting cylinder operate simultaneously, positioning the metering pushing-in limiting plate and the metering pressing limiting block on the upper and lower sides of the metering plate, respectively. The tilting and moving cylinder then operates; the metering pressing limiting cylinder can also operate at the rear end of the metering plate, flush with the rear end of the guide limiting groove. During the tilting and moving cylinder operation, the structure of the metering pushing-in limiting plate allows the metering plate to move backward. Since the metering pressing limiting block does not move, the scraper section can scrape the floating medicine on the metering plate. Due to the limitations of the tilting cylinder, when the cup at the front end of the metering plate is pushed in, the metering push-in limit plate needs to be moved forward away from the metering plate first. Then, under the action of the metering plate push-in limit cylinder, the rear end of the metering push-in limit plate is made flush with the metering plate. Then, the tilting cylinder works to push the entire metering plate into the metering plate groove through the rear end of the metering push-in limit plate.

[0078] 3. Flipping. After the entire metering plate is pushed into the metering plate slot, the flipping movement cylinder operates, driving the metering push-in limit plate forward, causing the rear end of the metering push-in limit plate to leave the flipping plate. Then, the metering plate flipping cylinder operates, and through the cooperation of the flipping gear and flipping rack, the flipping shaft is rotated, thereby flipping the metering plate. After the metering plate flips, the uncompacted propellant located in the metering hole will fall out.

[0079] 4. Pushing out. The flipping moving cylinder and the metering plate pushing limit cylinder work to make the rear end of the metering pushing limit plate flush with the front end of the metering plate, and the metering pushing plate is located on the lower side of the metering plate. Then the flipping ejection cylinder works to push the metering plate out of the metering plate slot through the flipping ejection block. When the front end of the metering plate contacts the front end of the metering pushing limit plate, the flipping moving cylinder simultaneously drives the metering pushing limit plate forward. When it moves into position, the flipping ejection cylinder stops moving. At this time, the flipping moving cylinder and the metering plate pushing limit cylinder, along with the metering pushing limit plate, leave the metering plate.

[0080] 5. Return to position. The tilting and lifting cylinder reverses its operation, causing the metering plate to fall onto the conveyor line. Then, the tilting and blocking cylinder returns to its original position, allowing the metering plate to move under the action of the conveyor line.

[0081] To facilitate the input and output of the metering plates within the explosion-proof chamber, conveyor line A includes a medicated conveyor line 68 installed inside the explosion-proof chamber, a medicated input line 69 for conveying un-medicated metering plates from outside the explosion-proof chamber to the medicated conveyor line, and a medicated output line 70 for conveying completed metering plates from the medicated conveyor line to outside the explosion-proof chamber. Both the medicated application machine and the metering plate flipping device are located on the medicated conveyor line. Preferably, the medicated conveyor line extends horizontally from left to right, the medicated input line extends vertically from the left side of the medicated conveyor line from back to front, and the medicated output line extends vertically from the right side of the medicated conveyor line from front to back. To facilitate the movement of the metering plate between the application input line and the application conveyor line, and between the application conveyor line and the application output line, a transfer device is installed at the rear end of the application input line and the application output line, that is, at both ends of the application conveyor line. The transfer device includes a transfer lifting component and a transfer moving component, both of which are implemented using cylinders.

[0082] In this application, to further ensure safety, the motor on the conveyor line is an explosion-proof motor, and the other power mechanisms are powered by cylinders. At the same time, a main switch is installed outside the explosion-proof room. When a worker enters the explosion-proof room, pressing the main switch will shut down all the equipment inside the explosion-proof room. The equipment will only be turned on to apply the medicine after the worker leaves the explosion-proof room.
