Detailed Implementation

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0027] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 7The diagram shows a structural representation of a fireworks and firecrackers quantitative charging device according to an embodiment of the present invention. It includes a workbench 1, a support plate 2 rotatably mounted on the surface of the workbench 1, and a plurality of equally spaced, annular support holes 21 on the surface of the support plate 2. A fixing plate 31 is fixedly mounted on the surface of the workbench 1, and a material-holding funnel 3 is fixedly mounted in the center of the fixing plate 31. A charging tube 32 is provided at the bottom of the material-holding funnel 3, and a quantitative charging mechanism 4 is provided inside the charging tube 32. The quantitative charging mechanism 4 includes a feeding component 41 and an adjusting component 42. The feeding component 41 consists of a sealing part 411. The system consists of a through section 412 and a sealing section 411 disposed inside the drug delivery tube 32. The sealing section 411 is used to control the drug delivery tube 32 to be in a closed state. The through section 412 is located on the surface of the support plate 2 and is connected to the sealing section 411. The through section 412 is used to control the drug delivery tube 32 to intermittently switch to the through state. The adjusting component 42 is located on the surface of the drug delivery tube 32. The adjusting component 42 is used to adjust the amount of drug delivered by the drug delivery tube 32 in a single operation. The bottom wall of the worktable 1 is provided with a driving component 5, which is connected to the support plate 2. The driving component 5 is used to control the support plate 2 to rotate intermittently on the surface of the worktable 1.

[0029] A batch of pyrotechnic powder is placed in the material funnel 3. Initially, the sealing part 411 controls the guide tube 32 to be in a closed state, and the sealing part 411 stores a certain amount of pyrotechnic powder in the guide tube 32. Multiple firecracker paper tubes are inserted into multiple carrier holes 21 respectively. During use, the drive component 5 controls the carrier plate 2 to rotate at a certain angle on the surface of the workbench 1 at equal intervals (the certain angle is the angle that is divided equally by the number of carrier holes 21 of 360 degrees). When the carrier plate 2 rotates, it drives the firecracker paper tubes in the carrier holes 21 to rotate synchronously. When the firecracker paper tube rotates to the point directly below the guide tube 32, the through part 412 controls the guide tube 32 to switch to the open state, and the certain amount of pyrotechnic powder stored in the guide tube 32 can automatically fall down into the firecracker paper tube. After the pyrotechnic powder falls into the firecracker paper tube, the drive component 5 drives the carrier plate 2 to rotate again at a certain angle. While the carrier plate 2 is rotating, the sealing part 411 controls the guide tube 32 to switch to a closed state again, and a fixed amount of pyrotechnic powder is stored in the guide tube 32. After the carrier plate 2 controls the next firecracker paper tube to move directly below the guide tube 32, a fixed amount of pyrotechnic powder can be added to the firecracker paper tube again. This cycle repeats continuously, allowing for the metered filling of the firecracker paper tubes. While the carrier plate 2 rotates intermittently, workers can continuously insert firecracker paper tubes to be filled into the carrier hole 21 and sequentially remove filled firecracker paper tubes from the carrier hole 21. When it is necessary to adjust the amount of pyrotechnic powder according to different needs, the adjusting component 42 and the sealing part 411 work together to easily adjust the amount of pyrotechnic powder stored in the guide tube 32.

[0030] like Figure 1 , Figure 2 , Figure 3 As shown, in a preferred embodiment of the present invention, the drive assembly 5 includes a rotating column 51 rotatably mounted on the surface of the worktable 1, a bearing plate 2 fixedly mounted on the top of the rotating column 51, the bottom end of the rotating column 51 extending to the bottom of the worktable 1 and fixedly mounted with a positioning gear plate 52, a fixing frame 53 fixedly mounted on the bottom wall of the worktable 1, a motor 54 fixedly mounted on the surface of the fixing frame 53, a transmission plate 55 fixedly mounted on the output shaft of the motor 54, an arc-shaped transmission rack 56 fixedly mounted on the surface of the transmission plate 55, and the transmission rack 56 meshing with the positioning gear plate 52.

[0031] In operation, motor 54 drives transmission disc 55 to rotate, which in turn drives transmission rack 56 to rotate synchronously. When transmission rack 56 meshes with positioning gear disc 52, the meshing transmission between transmission rack 56 and positioning gear disc 52 drives rotating column 51 to rotate around its own axis. Rotating column 51 drives bearing disc 2 to rotate synchronously on the surface of worktable 1. When transmission rack 56 and positioning gear disc 52 separate, bearing disc 2 stops rotating on the surface of worktable 1. Transmission rack 56 continues to rotate, and bearing disc 2 rotates intermittently on the surface of worktable 1 at a certain angle.

[0032] like Figure 3 , Figure 4 , Figure 5 , Figure 7 As shown, in a preferred embodiment of the present invention, the sealing part 411 includes an upper sealing plate 4111 slidably mounted on the surface of the drug guide tube 32, and a lower sealing plate 4112 slidably mounted on the surface of the drug guide tube 32 below the upper sealing plate 4111. A drug storage cavity is formed between the upper sealing plate 4111 and the lower sealing plate 4112. An upper drug guide port 4113 is opened on the surface of the upper sealing plate 4111, and a lower drug guide port 4114 is opened on the surface of the lower sealing plate 4112. One end of the upper sealing plate 4112 extends to the outside of the drug guide tube 32 and is fixedly mounted with a positioning plate 4115. One end of the lower sealing plate 4112 extends to the outside of the drug guide tube 32 and is connected to the positioning plate 4115. A compression spring 4116 is fixedly mounted on the side wall of the drug guide tube 32, and the extension end of the compression spring 4116 is connected to the positioning plate 4115.

[0033] The compression spring 4116 applies a pushing force to the positioning plate 4115, positioning the positioning plate 4115 in a state away from the guide tube 32. The positioning plate 4115 positions the upper sealing plate 4111 and the lower sealing plate 4112 on the surface of the guide tube 32. The upper guide port 4113 on the surface of the upper sealing plate 4111 is aligned with the inner cavity of the guide tube 32, and the lower guide port 4114 on the surface of the lower sealing plate 4112 is offset from the inner cavity of the guide tube 32. At this time, the pyrotechnic powder in the feeding funnel 3 falls through the upper guide port 4113 onto the upper sealing plate 4111 and the lower sealing plate 4112. Inside the storage chamber, when the bearing plate 2 rotates, the through part 412 pushes the positioning plate 4115 to move toward the guide tube 32. The positioning plate 4115 pushes the upper sealing plate 4111 and the lower sealing plate 4112 to move synchronously. At this time, the upper guide port 4113 is first misaligned with the inner cavity of the guide tube 32. After the upper guide port 4113 is misaligned with the inner cavity of the guide tube 32, the lower guide port 4114 is aligned with the inner cavity of the guide tube 32. At this time, the bottom of the storage chamber switches to the through state, and a certain amount of pyrotechnic powder in the storage chamber can fall from the guide tube 32 into the firecracker paper tube directly below. After a single loading, when the carrying plate 2 rotates again, the through section 412 releases the restriction on the positioning plate 4115. The compression spring 4116 pushes the positioning plate 4115 to move away from the guide tube 32 back to its original position. At this time, the upper guide port 4113 is aligned with the inner cavity of the guide tube 32 again, and the lower guide port 4114 is misaligned with the inner cavity of the guide tube 32 again. The measured amount of pyrotechnic powder in the holding funnel 3 passes through the upper guide port 4113 and moves back into the storage cavity. This cycle repeats, allowing measured amounts of pyrotechnic powder to be discharged from the guide tube 32 and placed into the firecracker paper tube in sequence.

[0034] like Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, in a preferred embodiment of the present invention, the through portion 412 includes a crossbar 4121 fixedly installed on the side wall of the positioning plate 4115. A control block 4122 is fixedly installed at the end of the crossbar 4121 away from the positioning plate 4115. The control block 4122 is made of magnetic material. A plurality of equally spaced fixing rods 4123 are fixedly installed on the surface of the bearing plate 2. A magnetic plate 4124 is fixedly installed at the top end of the fixing rods 4123.

[0035] The carrier plate 2 positions the fixing rod 4123 and the magnetic plate 4124. When the carrier plate 2 rotates, it drives the magnetic plate 4124 to rotate synchronously. When the magnetic plate 4124 is in contact with the control block 4122, the magnetic plate 4124 is connected to the control block 4122 as a whole by magnetic attraction. The rotation of the magnetic plate 4124 drives the control block 4122 to move synchronously, and the control block 4122 drives the positioning plate 4115 to move synchronously towards the drug delivery tube 32. When the carrier plate 2 rotates again after a single filling, when the elastic thrust of the compression spring 4116 is greater than the magnetic attraction between the magnetic plate 4124 and the control block 4122, the magnetic plate 4124 and the control block 4122 separate. The compression spring 4116 pushes the control block 4122 to move away from the drug delivery tube 32 back to its original position. This cycle repeats, allowing the positioning plate 4115 to move intermittently back and forth.

[0036] like Figure 3 , Figure 4 , Figure 6 , Figure 7 As shown, in a preferred embodiment of the present invention, the drug delivery tube 32 is composed of an upper drug delivery tube 321 and a lower drug delivery tube 322. The adjusting assembly 42 includes an inner ring 421 fixedly installed at the top end of the lower drug delivery tube 322. The inner ring 421 is slidably connected to the inner sidewall of the upper drug delivery tube 321 in the vertical direction. The sidewall of the inner ring 421 has a plurality of snap-fit ​​holes 422. The inner sidewall of the upper drug delivery tube 321 has a storage hole 423. A snap-fit ​​post 424 is slidably installed inside the hole 423. A return spring 425 is fixedly installed inside the receiving hole 423. The telescopic end of the return spring 425 is connected to the snap-fit ​​post 424. A traction cable 426 is fixedly installed at one end of the snap-fit ​​post 424 located inside the receiving hole 423. The traction cable 426 extends to the outside of the upper drug guide tube 321 and is fixedly connected to a control ring 427. The end of the lower sealing plate 4112 is slidably connected to the positioning plate 4115.

[0037] Initially, the return spring 425 applies a pushing force to the locking post 424, causing the locking post 424 to insert into the locking hole 422 and thus position the inner ring 421. When it is necessary to adjust the amount of pyrotechnic charge, the control ring 427 is pushed to move on the surface of the upper propellant tube 321. The control ring 427 and the traction cable 426 cooperate to pull the locking post 424 towards the receiving hole 423. After the locking post 424 separates from the locking hole 422, the lower propellant tube 322 can be easily pulled to adjust the volume of the propellant storage chamber. When the propellant storage chamber is adjusted to the appropriate volume, the control ring 427 is released, and the return spring 425 pushes the locking post 424 to insert into the corresponding locking hole 422 again, thus easily fixing the position of the lower propellant tube 322.

[0038] like Figure 1 , Figure 3As shown, in a preferred embodiment of the present invention, a clearing component 6 is provided inside the material-holding funnel 3. The clearing component 6 includes a stirring rod 61, a support part 62, and a rotating part 63. The support part 62 is located inside the material-holding funnel 3 and is connected to the stirring rod 61. The support part 62 is used to position the stirring rod 61 in the inner cavity of the material-holding funnel 3 so that the stirring rod 61 is directly above the drug delivery tube 32. The rotating part 63 is connected to the support part 62 and is used to control the stirring rod 61 to rotate intermittently.

[0039] The pyrotechnic powder is placed into the feeding funnel 3. The support part 62 positions the stirring rod 61 directly above the guide tube 32. When the bearing plate 2 rotates, the rotating part 63 controls the stirring rod 61 to stir the pyrotechnic powder directly above the guide tube 32, which can effectively prevent the pyrotechnic powder from failing to move into the guide tube 32 under the action of cohesion.

[0040] like Figure 1 , Figure 3 , Figure 8 As shown, in a preferred embodiment of the present invention, the support part 62 includes a plurality of support rods 621 fixedly installed in the inner cavity of the material funnel 3. The plurality of support rods 621 are fixedly installed together in a vertical cylinder 622. A central shaft 623 is rotatably installed inside the vertical cylinder 622. The bottom end of the central shaft 623 extends to the bottom of the vertical cylinder 622 and is connected to the stirring rod 61.

[0041] The support rod 621 positions the vertical cylinder 622, which in turn positions the central shaft 623. The vertical cylinder 622 protects the central shaft 623, effectively preventing the pyrotechnics from coming into contact with the central shaft 623 from all directions and affecting its rotation. The central shaft 623 positions the stirring rod 61. When the bearing plate 2 rotates, the rotating part 63 controls the central shaft 623 to rotate around its own axis. The central shaft 623 drives the stirring rod 61 to rotate synchronously above the propellant tube 32.

[0042] like Figure 1 , Figure 3 , Figure 8 As shown, in a preferred embodiment of the present invention, the rotating part 63 includes a guide gear disk 631 fixedly mounted on the top end of the central shaft 623, a column 632 fixedly mounted in the middle of the bearing disk 2, and a guide gear ring 633 fixedly mounted on the top end of the column 632 through a bracket, the guide gear ring 633 meshing with the guide gear disk 631.

[0043] The bearing plate 2 positions the column 632 and the guide gear ring 633. When the bearing plate 2 rotates, it drives the guide gear ring 633 to rotate synchronously. The guide gear ring 633 meshes with the guide gear plate 631, which can drive the central shaft 623 to rotate around its own axis.

[0044] like Figure 1 , Figure 2 , Figure 3 As shown, in a preferred embodiment of the present invention, the side wall of the bearing plate 2 is provided with a limiting member 7, the limiting member 7 including a plurality of equally spaced inner magnetic sheets 71 fixedly installed on the side wall of the bearing plate 2, a plurality of support rods 72 are fixedly installed on the surface of the worktable 1, and an outer magnetic sheet 73 is fixedly installed at the top end of the support rods 72.

[0045] When the bearing disk 2 rotates, it drives the inner magnetic sheet 71 to rotate synchronously. When the transmission rack 56 and the positioning rack 52 separate from each other, the inner magnetic sheet 71 and the outer magnetic sheet 73 are connected into a whole by magnetic attraction. At this time, the bearing disk 2 remains stable and stationary, effectively preventing the bearing disk 2 from rotating under inertia.

[0046] like Figure 3 As shown, in a preferred embodiment of the present invention, the side wall of the bearing hole 21 is provided with a plurality of side grooves 8, an extrusion plate 81 is rotatably installed in the side groove 8, and a positioning spring 82 is fixedly installed in the side groove 8, with the extension end of the positioning spring 82 connected to the extrusion plate 81.

[0047] Inserting the firecracker paper tube into the bearing hole 21, multiple extrusion plates 81 extrude and position the firecracker paper tube, which can effectively improve the stability of the firecracker paper tube.

[0048] The working principle of this invention is as follows: A batch of pyrotechnic powder is placed in the feeding funnel 3. Initially, the compression spring 4116 applies a pushing force to the positioning plate 4115, which is in a state away from the guide tube 32. The positioning plate 4115 positions the upper sealing plate 4111 and the lower sealing plate 4112 on the surface of the guide tube 32. The upper guide port 4113 on the surface of the upper sealing plate 4111 is aligned with the inner cavity of the guide tube 32, while the lower guide port 4114 on the surface of the lower sealing plate 4112 is offset from the inner cavity of the guide tube 32. At this time, the pyrotechnic powder in the feeding funnel 3 falls through the upper guide port 4113 into the storage cavity between the upper sealing plate 4111 and the lower sealing plate 4112. Multiple firecracker paper tubes are then inserted into multiple bearing holes 21.

[0049] In operation, motor 54 drives transmission disc 55 to rotate, which in turn drives transmission rack 56 to rotate synchronously. When transmission rack 56 meshes with positioning rack 52, the meshing transmission drives rotating column 51 to rotate around its own axis. Rotating column 51 drives bearing plate 2 to rotate synchronously on the surface of worktable 1. When transmission rack 56 and positioning rack 52 separate, bearing plate 2 stops rotating on the surface of worktable 1. Transmission rack 56 continues to rotate, and bearing plate 2 rotates intermittently on the surface of worktable 1 at a certain angle. When bearing plate 2 rotates, it drives the firecracker paper tube in bearing hole 21 to rotate synchronously. When bearing plate 2 rotates, it drives magnetic plate 4124 to rotate synchronously. When magnetic plate 4124 is in contact with control block 4122, magnetic plate 4124 is connected to control block 4122 as a whole by magnetic attraction. When the magnetic plate 4124 rotates, it drives the control block 4122 to move synchronously. The control block 4122 drives the positioning plate 4115 to move synchronously towards the guide tube 32. The positioning plate 4115 pushes the upper sealing plate 4111 and the lower sealing plate 4112 to move synchronously. At this time, the upper guide port 4113 is first misaligned with the inner cavity of the guide tube 32. After the upper guide port 4113 is misaligned with the inner cavity of the guide tube 32, the lower guide port 4114 is aligned with the inner cavity of the guide tube 32. At this time, the bottom of the storage chamber switches to the through state, and a certain amount of pyrotechnic powder in the storage chamber can fall from the guide tube 32 into the firecracker paper tube directly below. After a single loading, when the carrier plate 2 rotates again, the magnetic plate 4124 releases the restriction on the positioning plate 4115, and the compression spring 4116 pushes the positioning plate 4115 to move away from the guide tube 32 back to its original position. At this time, the upper guide port 4113 is aligned with the inner cavity of the guide tube 32 again, and the lower guide port 4114 is misaligned with the inner cavity of the guide tube 32 again. The measured amount of pyrotechnic powder in the feeding funnel 3 passes through the upper guide port 4113 and moves back into the storage cavity. This cycle repeats, allowing measured amounts of pyrotechnic powder to be discharged from the guide tube 32 and placed into the firecracker paper tube in sequence.

[0050] When it is necessary to adjust the amount of pyrotechnic charge, push the control ring 427 to move on the surface of the upper charge tube 321. The control ring 427 and the traction cable 426 cooperate to pull the locking pin 424 into the receiving hole 423. After the locking pin 424 separates from the locking hole 422, the lower charge tube 322 can be easily pulled to adjust the volume of the charge storage chamber. After the charge storage chamber is adjusted to the appropriate volume, release the control ring 427. The return spring 425 pushes the locking pin 424 to be inserted into the corresponding locking hole 422 again, so that the position of the lower charge tube 322 can be easily fixed.

[0051] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
