Detailed Embodiments
[0033] The following are specific embodiments of the present application. In combination with the accompanying drawings, the technical solutions of the present application will be further described. However, the present application is not limited to these embodiments. In the following description, specific details such as specific configurations and components are provided only to help comprehensively understand the embodiments of the present application. Therefore, those skilled in the art should clearly understand that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. In addition, descriptions of known functions and structures are omitted for clarity and conciseness.
[0034] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
[0035] The present application provides a fireworks raw material filling device, which can be used for filling the raw materials of the inner cylinder of fireworks or the outer cylinder of fireworks. Specifically, when the fireworks raw material filling device is applied to fill the inner cylinder of fireworks, it can be used to fill the bright beads, oxidant, reductant, filler and ignition fixing agent into the inner cylinder of fireworks. When the fireworks raw material filling device is applied to fill the outer cylinder of fireworks, it can be used to fill the military nitrate into the outer cylinder of fireworks.
[0036] Reference Figure 1 and Figure 2 , the fireworks raw material filling device includes a fixed bracket 10, a material box 20, a first driving source 30, and a material blocking assembly 40. Also referring to Figures 3 - 5 , the material box 20 has a storage space 21 inside for accommodating the fireworks raw materials, and a bottom structure 22 of the storage space 21 is formed below the storage space 21; a quantitative hole 23 is arranged in an array on the bottom structure 22; the material box 20 can rotate relative to the fixed bracket 10. The first driving source 30 is used to drive the bottom structure 22 of the storage space 21 to rotate and tilt, so that the raw materials in the storage space 21 move to the area where the quantitative hole 23 is located or leave the area where the quantitative hole 23 is located. The material blocking assembly 40 can seal the quantitative hole 23 from below the quantitative hole 23 or open the quantitative hole 23.
[0037] Specifically, the first driving source 30 can drive the bottom structure 22 of the material box 20 to rotate and tilt, so that the raw materials in the storage space 21 slide, thereby realizing that the raw materials in the storage space 21 move to the area where the quantitative hole 23 is located or leave the area where the quantitative hole 23 is located.
[0038] When the fireworks raw material filling device is working, first, the raw materials in the storage space 21 are poured into the metering hole 23, and then the raw materials in the metering hole 23 are used for corresponding filling. Specifically, first, the material blocking component 40 seals the metering hole 23, and the first driving source 30 drives the bottom structure 22 of the storage space 21 to rotate and tilt so that the raw materials in the storage space 21 move to the area where the metering hole 23 is located. The raw materials in the storage space 21 enter the metering hole 23 and fill the metering hole 23. Then, the first driving source 30 drives the bottom structure 22 of the storage space 21 to rotate and tilt so that the raw materials in the storage space 21 leave the area where the metering hole 23 is located. At this time, when the material blocking component 40 opens the metering hole 23, the raw materials in the metering hole 23 fall into the corresponding outer cylinder or inner cylinder. The above filling process fills the fireworks raw materials into the metering hole by tilting the material box, without using mechanical components for leveling. The friction and extrusion suffered by the fireworks raw materials are small, and it is safer.
[0039] Furthermore, the metering hole 23 is arranged at a position close to the front side edge of the storage space 21; the first driving source 30 can drive the bottom structure 22 of the storage space 21 to tilt forward so that the raw materials in the storage space 21 move to the area where the metering hole 23 is located, or drive the bottom structure 22 of the storage space 21 to tilt backward so that the raw materials in the storage space 21 leave the area where the metering hole 23 is located. The front side and the rear side are the relative two sides in the front-rear direction x of the storage space 21.
[0040] Specifically, in Figure 5 the structure shown, the metering hole 23 is located at the front side edge of the storage space 21. When the first driving source 30 drives the bottom structure 22 of the storage space 21 to tilt forward, the raw materials in the storage space 21 slide forward in the material box 20 and reach the area where the metering hole 23 is located to fill the metering hole 23. When the first driving source 30 drives the bottom structure 22 of the storage space 21 to tilt backward, the raw materials in the storage space 21 slide backward in the material box 20, so as to leave the area where the metering hole 23 is located. At this time, during the process of the metering hole 23 discharging materials, the raw materials in the storage space 21 will not be replenished into the metering hole 23, and the metering hole 23 can perform metered discharging.
[0041] Refer to Figures 1 - 4, in an embodiment of the present application, the fireworks raw material filling device further includes a second driving source 50, and the second driving source 50 is used to drive the material box 20 to reciprocate in the left-right direction y. Specifically, under the drive of the second driving source 50, the material box 20 reciprocates in the left-right direction at a set frequency. The reciprocating movement of the material box 20 in the left-right direction can make the raw materials in the material box more evenly distributed in the left-right direction, so as to facilitate the realization of the material covering and filling all the metering holes. In a specific technical solution, when the first driving source 30 drives the bottom structure 22 of the storage space 21 to tilt forward, the raw materials in the storage space 21 slide forward to the front side of the material box 20 and reach the area where the metering holes 23 are located. At this time, the second driving source 50 drives the material box 20 to reciprocate in the left-right direction, making the raw materials in the material box more evenly distributed in the left-right direction, so as to cover all the material holes.
[0042] In an embodiment of the present application, the fireworks raw material filling device further includes a third driving source 60, and the third driving source 60 is used to drive the material box 20 to move in the front-back direction x. Refer to Figure 9 , the conveyor line 200 is located in front of the fireworks raw material filling device 100. When it is necessary to fill the inner cylinder or outer cylinder of the fireworks on the conveyor line 200, the third driving source 60 can drive the material box 20 forward, so that the metering holes 23 on the front side of the material box enter above the inner cylinder or outer cylinder of the fireworks to be filled for filling. And after the filling is completed, the third driving source 60 can drive the material box 20 to retreat, and the material box 20 exits the position above the conveyor line 200. After exiting the position above the conveyor line 200, the first driving source 30 can drive the material box to rotate again, so that the raw materials in the storage space 21 are poured into the metering holes 23 for the next filling.
[0043] In an embodiment of the present application, refer to Figures 1 - 4 , and Figure 8 , a translation support 70 and a rotation support 80 are provided between the material box 20 and the fixed support 10. The translation support 70 is slidably mounted on the fixed support 10, and the third driving source 60 is used to drive the translation support 70 to slide back and forth relative to the fixed support 10; the rotation support 80 is rotatably mounted on the translation support 70, and the first driving source 30 is used to drive the rotation support 80 to rotate relative to the translation support 70; the material box 20 is slidably mounted on the rotation support 80, and the second driving source 50 is used to drive the material box 20 to slide left and right relative to the rotation support 80.
[0044] Specifically, the translation bracket 70 and the rotating bracket 80 are located between the material box 20 and the fixed bracket 10. The translation bracket 70 is installed on the fixed bracket 10 and can slide forward and backward under the drive of the third driving source 60. The rotating bracket 80 is installed on the translation bracket 70, so it can move forward and backward with the translation bracket 70, and can rotate under the drive of the first driving source 30. The material box 20 is installed on the rotating bracket 80, and can move forward and backward with the translation bracket 70, rotate with the rotating bracket 80, and the material box 20 can slide left and right under the drive of the second driving source 50. Figure 1 , the translation bracket 70 can move in the front-to-back direction x relative to the fixed bracket 10, the rotating bracket 80 can rotate in the front-to-back direction R relative to the translation bracket 70, and the material box 20 can move in the left-to-right direction y relative to the rotating bracket 80. Under this structure, multiple motion superpositions of the material box 20 can be achieved by setting the translation bracket 70 and the rotating bracket 80.
[0045] refer to Figure 6 and Figure 7 In one embodiment of the present application, the material baffle assembly 40 includes a material baffle plate 41 and a fourth driving source 42; the material baffle plate 41 is located below the quantitative hole 23, and the fourth driving source 42 is used to drive the material baffle plate 41 to move, so that the material baffle plate 41 seals the quantitative hole 23 or opens the quantitative hole 23.
[0046] Driven by the fourth driving source 42, the material blocking plate 41 can seal the quantitative hole 23 or open the quantitative hole 23. In one embodiment of the present application, a limiting plate 43 is also fixed on the material box 20, and a material drop hole 431 is processed on the limiting plate 43, and the material drop hole 431 is aligned one by one with the quantitative hole 23. The material blocking plate 41 is located between the limiting plate 43 and the bottom structure 22, and a material passing hole 411 is provided on the material blocking plate 41, and the material passing hole 411 corresponds one by one with the quantitative hole 23. The fourth driving source 42 can drive the material blocking plate 41 to move so that the material passing hole 411 on it is aligned with or staggered with the quantitative hole 23. When the feeding hole 411 is aligned with the quantitative hole 23, the quantitative hole 23, the feeding hole 411 on the material blocking plate 41, and the material drop hole 431 on the limit plate 43 are aligned one by one, and the raw material in the quantitative hole 23 can fall into the corresponding outer cylinder or inner cylinder through the feeding hole 411 on the material blocking plate 41 and the material drop hole 431 on the limit plate 43. When the feeding hole 411 is staggered with the quantitative hole 23, the quantitative hole 23 is sealed by the material blocking plate 41.
[0047] refer to Figure 4, in an embodiment of the present application, a vibrator 110 is further installed on the material box 20. The vibrator 110 is used to drive the material box 20 to vibrate when the material falls through the metering hole 23. Here, the vibrator 110 can specifically be a pneumatic vibrator. When the raw material in the storage space 21 moves to the area where the metering hole 23 is located, the vibrator can make the raw material in the material box more evenly distributed on the bottom structure, promoting the material to cover and fill all the metering holes. In addition, when the material falls through the metering hole, the vibrator can also promote the full discharge of the metering hole and avoid residue.
[0048] Reference Figure 5 , in an embodiment of the present application, a material pushing assembly 90 is provided on the material box 20; the material pushing assembly 90 includes a material pusher 91 and a fifth driving source 92; the fifth driving source 92 can drive the material pusher 91 to act, so that the material pusher 91 penetrates downward into the metering hole 23. When the material falls through the metering hole, the fifth driving source 92 drives the material pusher 91 to penetrate downward into the metering hole 23, so that the raw material in the metering hole slides down fully and residue is avoided.
[0049] The embodiment of the present application also provides a production line, which has the fireworks raw material filling equipment provided in the previous part. Here, the production line can be a fireworks inner tube production line or a production line of combined fireworks. When the production line is a fireworks inner tube production line, the fireworks raw material filling equipment is used to fill the fireworks inner tube, and fill the fireworks inner tube with bright beads, oxidants, reducers, fillers, solid primers, or a mixture of multiple raw materials. When the production line is a production line of combined fireworks, the fireworks raw material filling equipment is used to fill the fireworks outer tube, and fill the fireworks outer tube with military nitrates.
[0050] Specific reference Figure 9 , a conveyor 200 is arranged on the production line. The conveyor 200 is located in front of the fireworks raw material filling equipment 100. When it is necessary to fill the fireworks inner tube or the fireworks outer tube on the conveyor 200, the third driving source 60 can drive the material box 20 to move forward, so that the metering hole 23 on the front side of the material box enters above the fireworks inner tube or the fireworks outer tube to be filled for filling. And after the filling is completed, the third driving source 60 can drive the material box 20 to retreat, and the material box 20 exits the position above the conveyor 200. After exiting the position above the conveyor 200, the first driving source 30 can drive the material box to rotate again, so that the raw material in the storage space 21 is poured into the metering hole 23 for the next filling.
[0051] In the fireworks raw material loading device provided by the embodiments of the present application, the first driving source rotates and tilts the material box to move the raw materials in the storage space to the area where the metering holes are located, so as to achieve the loading of the metering holes.
