Description

Technical Field

[0001] This invention relates to the field of pyrotechnic filling production technology, and more specifically, to a production equipment and method for filling pyrotechnics. Background Technology

[0002] The content in this section only provides background information related to this invention and may not constitute prior art.

[0003] Pyrotechnic filling production refers to the process of precisely injecting sensitive energetic materials, such as detonators and propellants, into a shell. It is widely used in aerospace, weaponry, and civilian blasting fields. Because the agents are extremely sensitive to friction, static electricity, and impact, the production environment requires high safety and high precision. Under the traditional technological background, the filling process relies on manual or semi-automatic equipment, which has problems such as low efficiency and poor consistency. With the development of pyrotechnics towards miniaturization and integration, higher requirements are placed on the automation, reliability, and protection capabilities of filling equipment.

[0004] Existing pyrotechnic filling production equipment typically includes a feeding system, a metering dispensing mechanism, a filling head, and a shell conveying line. Specifically, it uses a screw to rotate and push the agent to the metering chamber, and a pneumatic piston to push the propellant into the shell, or uses an inclined slide to achieve gravity feeding. The filling amount is controlled by a metering plate. The operation is mostly a step-by-step process: first, the empty shell is positioned, then the agent is metered and dispensed, and finally, it is inserted into the shell to complete the filling.

[0005] However, the above-mentioned technologies have the following drawbacks: in existing pyrotechnic filling equipment, the positioning and clamping of the shell are mostly completed by manual assistance or semi-automatic clamps. After the operator places the shell on the simple positioning seat, it is fixed by manually tightening or pressing. This relies heavily on the operator's skill level, and the positioning accuracy and stability are insufficient, which seriously restricts the consistency and production efficiency of pyrotechnic agent filling. Summary of the Invention

[0006] In order to solve the above-mentioned technical problems, the purpose of this invention is to provide a production equipment and method for filling pyrotechnic materials, which can improve the consistency of pyrotechnic material filling and production efficiency.

[0012] In some possible embodiments, the transmission device includes a first rack, a second rack, and a transmission gear. The transmission gear is rotatably disposed within the mounting cavity. Two first racks are provided, with the two first racks respectively disposed on the two side walls of the drive block. The second rack is disposed on the side wall of the transmission frame. Both the first rack and the second rack mesh with the transmission gear.

[0014] In some possible embodiments, the drive source is configured as a drive motor, the output end of the drive source is connected to a drive rod, the drive rod has a threaded groove along its length, the drive block has a connecting hole threaded to the drive rod, the inner wall of the mounting cavity has a guide groove along the conveying direction of the housing, a guide block is fixedly mounted on the drive block, and the guide block is slidably connected to the guide groove.

[0015] In some possible embodiments, an annular groove is provided on the mounting platform, and an annular block is rotatably disposed in the annular groove. The top of the annular block is fixedly connected to the bottom of the clamping part, and the rotating assembly is used to drive the annular block to move in the annular groove.

[0016] In some possible embodiments, the rotating assembly includes a rotating motor and a drive disk. The mounting portion has a receiving cavity, the rotating motor is disposed in the receiving cavity, the drive disk is rotatably disposed in the receiving cavity and is connected to the output shaft of the rotating motor. The inner wall of the annular groove has a strip-shaped hole communicating with the receiving cavity.

[0017] In some possible embodiments, the drive disk has a mounting hole, and a mounting block is slidably disposed in the mounting hole along the radial direction of the drive disk. The side of the mounting block away from the mounting hole is fixedly connected to the drive tooth. A spring is disposed in the mounting hole, with one end of the spring fixedly connected to the drive tooth and the other end fixedly connected to the inner wall of the mounting hole.

[0018] On the other hand, the present invention also provides a production method for filling pyrotechnic items.

[0019] A method for producing pyrotechnic items, using the above-mentioned pyrotechnic item filling equipment, includes the following steps:

[0020] S1. Loading: The shell to be filled is conveyed to the mounting platform by the conveying mechanism and the shell is put into the clamping groove of the clamping part.

[0021] S2. Clamping: Start the drive assembly. The drive assembly drives the two clamping parts to move closer to each other, so that the arc-shaped clamping plate clamps the shell.

[0022] S3. Shift to the filling station, start the rotating assembly. The rotating assembly drives the clamping part and the clamped housing to rotate on the mounting table, so that the housing moves directly below the filling mechanism.

[0023] S4. Filling: Start the filling mechanism to fill the shell.

[0024] S5. Unloading: After loading is completed, start the drive assembly. The drive assembly drives the two clamping parts to move away from each other, causing the arc-shaped clamping plate to release the housing. The housing is then unloaded at the unloading mechanism.

[0025] In summary, the technical solutions of the embodiments of the present invention have at least the following advantages and beneficial effects:

[0026] 1. By setting a rotating component to drive the clamping part to rotate on the mounting table, the clamping part can sequentially rotate the shell from the loading position to directly below the filling mechanism, and then to the unloading mechanism, realizing the automatic flow of the shell between different work positions, reducing manual handling and positioning operations, and improving the continuity of filling operations and production efficiency.

[0027] 2. Two clamping components are slidably arranged in the clamping groove, and the ends of the clamping components are fixed with arc-shaped clamping plates with opposite concave surfaces. Under the drive of the drive component, the two arc-shaped clamping plates move closer to each other, which can achieve self-centering clamping of shells of different diameters, ensuring that the shell axis is aligned and stable with the filling mechanism, avoiding the filling off-center load problem caused by manual placement or simple positioning seat, and improving filling consistency.

[0028] 3. The drive assembly adopts a rack and pinion meshing structure of drive block, transmission gear and transmission frame, which converts the linear motion of drive block along the conveying direction into the opposite motion of two transmission frames perpendicular to the conveying direction. With the cooperation of the first elastic element in the abutment groove and the second elastic element on the transmission frame, the flexible transmission of clamping force and overload buffering are realized. It can reliably clamp the shell and avoid damage to the shell or accidental impact due to rigid clamping.

[0029] 4. During the filling process, the rotating component continues to start, and the slight vibrations generated by the spring contraction and release are transmitted to the clamping parts, thereby causing slight vibrations to the clamped shell. This effectively reduces the small gaps generated during the filling process and improves the quality and effect of the pyrotechnic agent filling. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0038] The following is for reference Figures 1 to 6 The present invention will be described in further detail below.

[0039] On the one hand, the present invention provides a production equipment and method for filling pyrotechnic items.

[0040] Reference Figure 1 , Figure 2 and Figure 3 A production equipment for filling pyrotechnic items includes a frame 1, a conveying mechanism 11 mounted on the frame 1, a mounting platform 2 fixedly mounted on the unloading end of the conveying mechanism 11, a clamping part 21 mounted on the mounting platform 2, a clamping groove 22 formed on the clamping part 21 for the shell to be filled to enter, a clamping member 23 slidably mounted in the clamping groove 22 for clamping the shell, the clamping part 21 being rotatably mounted on the mounting platform 2, and a rotating assembly 3 (such as...) mounted on the mounting platform 2. Figure 4As shown), the rotating assembly 3 is used to drive the clamping part 21 to rotate on the mounting platform 2. A filling mechanism 12 is provided on the frame 1, which is located above the mounting platform 2. A feeding mechanism 13 is provided on the frame 1, which is located on one side of the mounting platform 2. The rotating assembly 3 is used to drive the housing to move from the conveying mechanism 11 to the feeding mechanism 13.

[0041] like Figure 1 As shown, two mounting platforms 2 are provided on the frame 1, and two conveying mechanisms 11 are provided accordingly. The conveying directions of the two conveying mechanisms 11 are opposite to each other, so that the shell of the pyrotechnic item to be loaded can be conveyed from two different directions.

[0042] The shell is automatically fed into the clamping groove 22 by the conveying mechanism 11, and then the clamping part 21 is driven to rotate by the rotating component 3, so that the shell passes through the loading station, the filling station and the unloading station in sequence, realizing the automatic flow of the shell between different stations without manual handling and repeated positioning, thereby improving the continuity and production efficiency of pyrotechnic filling operations. At the same time, the filling mechanism 12 is fixed above the frame 1 to ensure the stability of the filling position.

[0043] Reference Figure 2 and Figure 3 An installation cavity 4 is provided on the inner wall of the clamping groove 22. Two clamping members 23 are provided in the clamping groove 22. The ends of the two clamping members 23 that are far apart from each other are slidably disposed in the installation cavity 4 perpendicular to the conveying direction. The ends of the clamping members 23 that are close to each other are fixedly provided with an arc-shaped clamping plate 24. The concave surfaces of the arc-shaped clamping plate 24 are arranged opposite each other. A driving assembly 5 is provided on the clamping part 21. The driving assembly 5 is used to drive the two clamping members 23 to move in a direction that is close to or far apart from each other.

[0044] The two arc-shaped clamping plates 24 can move synchronously towards each other under the drive of the drive component 5, and achieve self-centering clamping of shells of different diameters. This ensures that the axial position of the shell is stable during the filling process and avoids the filling mechanism 12 from being unable to accurately inject the agent due to shell displacement. The concave surface of the arc-shaped clamping plate 24 has a large contact area with the outer wall of the shell, and the clamping force is evenly distributed, reducing the risk of local pressure deformation of the shell.

[0045] like Figure 2 and Figure 3 As shown, in one embodiment of the present invention, the drive assembly 5 includes a drive source 51, a drive block 52, a transmission device 53, and a transmission frame 54.

[0046] Among them, reference Figure 3The drive source 51 is disposed on the clamping part 21. The drive block 52 is slidably disposed in the mounting cavity 4 along the conveying direction of the housing. The drive source 51 acts on the drive block 52 to move the drive block 52 in the mounting cavity 4. The transmission frame 54 is slidably disposed in the mounting cavity 4 along the conveying direction perpendicular to the housing. There are two transmission frames 54. The transmission frame 54 is connected to the clamping part 23 in a one-to-one correspondence. One end of the transmission device 53 is connected to the drive block 52, and the other end is connected to the transmission frame 54.

[0047] The drive source 51, through the drive block 52 and the transmission device 53, converts the linear motion along the conveying direction into the opposing motion of the two transmission frames 54 perpendicular to the conveying direction, thereby driving the clamping member 23 to open and close. This makes the arrangement direction of the drive source 51 perpendicular to the clamping motion direction, which is conducive to achieving a compact layout in a limited space, while avoiding structural interference caused by the drive source 51 being directly arranged behind the clamping member 23.

[0048] like Figure 3 As shown, the transmission device 53 includes a first rack 531, a second rack 532, and a transmission gear 533. The transmission gear 533 is rotatably disposed in the mounting cavity 4. Two first racks 531 are provided, which are respectively disposed on the two side walls of the drive block 52. The second rack 532 is disposed on the side wall of the transmission frame 54. Both the first rack 531 and the second rack 532 mesh with the transmission gear 533.

[0049] When the drive block 52 moves along the conveying direction, the two first racks 531 drive the transmission gear 533 to rotate, and the transmission gear 533 then drives the second racks 532 on the two transmission frames 54 to move in the opposite direction, thereby realizing that the two transmission frames 54 and the clamping parts 23 connected to them move synchronously towards or away from each other. The gear and rack meshing transmission has high motion synchronization and position repeatability, which can ensure that the clamping and releasing actions of the two arc-shaped clamps 24 on the shell are coordinated and consistent, avoiding the shell tilting caused by the lag of the action of the clamping part 23 on one side.

[0050] Reference Figure 3 The drive block 52 has an abutment groove 6 on its side wall. An abutment piece 61 is slidably disposed in the abutment groove 6. A first elastic member 62 is disposed in the abutment groove 6. The first elastic member 62 acts on the abutment piece 61. The side of the abutment piece 61 away from the first elastic member 62 is used to abut against the transmission frame 54. The clamping member 23 is slidably connected to the transmission frame 54 along the conveying direction perpendicular to the housing. A second elastic member 63 is disposed on the transmission frame 54. The second elastic member 63 acts on the clamping member 23 so that the two clamping members 23 have a tendency to move towards each other.

[0051] As one embodiment of the present invention, refer to Figure 3A buffer groove 64 is provided at the end of the transmission frame 54. A buffer block 65 is slidably disposed in the buffer groove 64. The buffer block 65 is fixedly connected to the clamping member 23. A second elastic member 63 is disposed in the buffer groove 64. The second elastic member 63 is configured as a compression spring. One end of the second elastic member 63 is fixedly connected to the buffer block 65, and the other end is fixedly connected to the inner wall of the buffer groove 64.

[0052] During the movement of the transmission frame 54, a continuous elastic force is first applied to the housing through the second elastic element 63. During the continuous movement, the first elastic element 62 is compressed by the transmission frame 54, and the pressure is further transmitted to the clamping member 23 through the transmission frame 54, which can further improve the clamping stability of the clamping member 23. At the same time, when encountering abnormal housing size or foreign objects, the first elastic element 62 and the second elastic element 63 allow the clamping member 23 to retract appropriately, which plays the role of overload buffer and improves the equipment's adaptability to housing tolerances.

[0053] As one embodiment of the present invention, refer to Figure 1 , Figure 2 and Figure 3 The drive source 51 is configured as a drive motor. The output end of the drive source 51 is connected to a drive rod 55. A threaded groove is provided on the drive rod 55 along its length. A connecting hole 56 is provided on the drive block 52 to be threadedly connected to the drive rod 55. A guide groove 57 is provided on the inner wall of the mounting cavity 4 along the conveying direction of the housing. A guide block 58 is fixedly provided on the drive block 52. The guide block 58 is slidably connected to the guide groove 57.

[0054] The drive motor drives the drive rod 55 to rotate, which in turn drives the drive block 52 to move linearly along the guide groove 57 through a threaded engagement. The threaded drive has a self-locking characteristic, so when the motor stops, the drive block 52 can maintain its position, thereby maintaining the clamping state of the clamping member 23 without continuous power supply. The engagement between the guide groove 57 and the guide block 58 restricts the rotational freedom of the drive block 52, ensuring the linearity and smoothness of the movement of the drive block 52, and thus ensuring the precise engagement of the transmission device 53.

[0055] In a preferred embodiment of the present invention, a pressure sensor may be provided on the side wall of the drive block 52 near the clamping member 23. When the housing to be filled comes into contact with the drive block 52, the pressure signal is sensed by the sensor, and then the pressure signal is converted into an electrical signal by the controller to control the subsequent drive source 51 to start.

[0056] Reference Figure 2 and Figure 4 An annular groove 7 is provided on the mounting platform 2. An annular block 71 is rotatably disposed in the annular groove 7. The top of the annular block 71 is fixedly connected to the bottom of the clamping part 21. The rotating component 3 is used to drive the annular block 71 to move in the annular groove 7.

[0057] The annular block 71 rotates within the annular groove 7, providing stable rotational support for the clamping part 21. The annular fit has a large contact area, which can withstand the weight of the clamping part 21 and the housing, as well as the lateral force that may be generated during loading, ensuring that the clamping part 21 does not tilt or shake during rotation, thus improving the positional repeatability accuracy of the housing after rotation.

[0058] As one embodiment of the present invention, refer to Figure 4 and Figure 5 The rotating assembly 3 includes a rotating motor 31 and a drive disk 32. A receiving cavity 8 is provided in the mounting part. The rotating motor 31 is disposed in the receiving cavity 8. The drive disk 32 is rotatably disposed in the receiving cavity 8 and is connected to the output shaft of the rotating motor 31. A strip hole 81 communicating with the receiving cavity 8 is provided on the inner wall of the annular groove 7. A drive gear ring 82 is provided on the side wall of the annular block 71. A plurality of drive teeth 83 are provided on the peripheral wall of the drive disk 32. The drive teeth 83 are used to mesh with the drive gear ring 82.

[0059] The rotating motor 31 drives the drive disk 32 to rotate. The drive teeth 83 on the drive disk 32 mesh with the drive ring 82 on the annular block 71 through the strip hole 81, thereby transmitting the rotational power of the motor to the clamping part 21. The gear meshing transmission can achieve precise angle control, so that the clamping part 21 has a certain position each time it rotates to the preset work position, avoiding slippage or angle deviation that may occur with belt drive.

[0060] Among them, reference Figure 5 The drive disk 32 has a mounting hole 84. A mounting block 85 is slidably disposed in the drive disk 32 along the radial direction of the mounting hole 84. The side of the mounting block 85 away from the mounting hole 84 is fixedly connected to the drive tooth 83. A spring is disposed in the mounting hole 84. One end of the spring is fixedly connected to the drive tooth 83, and the other end is fixedly connected to the inner wall of the mounting hole 84.

[0061] During normal rotation, the spring keeps the drive tooth 83 stably engaged with the drive tooth ring 82, ensuring the continuity of power transmission. During the filling operation, the rotating component 3 is continuously started. The periodic contraction and release of the spring due to the rotation of the drive disc 32 will generate a small vibration. This vibration is transmitted to the clamping member 23 through the ring block 71 and the clamping part 21, which in turn causes the clamped shell to vibrate slightly. The vibration can cause the agent particles injected by the filling mechanism 12 to rearrange, reduce the accumulation of voids between particles, improve the filling density, and thus improve the quality and effect of pyrotechnic filling.

[0062] On the other hand, the present invention also provides a production method for filling pyrotechnic items.

[0063] A method for producing pyrotechnic items, using the above-mentioned pyrotechnic item filling equipment, includes the following steps:

[0064] S1. Loading: The shell to be filled is conveyed to the mounting platform 2 by the conveying mechanism 11 and the shell is put into the clamping groove 22 of the clamping part 21.

[0065] S2. Clamping, start the drive assembly 5. The drive assembly 5 drives the two clamping pieces 23 to move closer to each other, so that the arc-shaped clamping plate 24 clamps the shell.

[0066] S3. Shift to the filling station and start the rotating assembly 3. The rotating assembly 3 drives the clamping part 21 and the clamped housing to rotate on the mounting platform 2, so that the housing moves directly below the filling mechanism 12.

[0067] S4. Filling: Start the filling mechanism 12 to fill the shell.

[0068] S5. After loading is completed, start the drive assembly 5. The drive assembly 5 drives the two clamping parts 23 to move away from each other, so that the arc-shaped clamping plate 24 releases the housing and the housing is unloaded at the unloading mechanism 13.

[0069] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
