Description

Technical Field

[0001] This utility model belongs to the technical field of fireworks production equipment, specifically relating to a sealing agent filling device. Background Technology

[0002] Fireworks, as a product with aesthetic and cultural value, involve multiple precise processes in their production. Among these, the sealing process of the inner tube is a crucial step, directly affecting the product's airtightness, ignition effect, and safety. Sealing agents typically use granular perlite powder with high compressibility and good flowability. However, traditional manual sealing methods have several drawbacks: First, manual operation makes it difficult to ensure consistent sealing quality, resulting in low product yield and inconsistent performance. Second, manual filling is inefficient and cannot meet the needs of large-scale production; furthermore, long-term exposure to the chemicals in the sealing agent increases the risk of occupational diseases for workers. While existing mechanized sealing technology partially solves the efficiency problem, the sealing agent filling equipment has a complex structure, poor adaptability, high maintenance costs, and poor adaptability to various sealing agents. Therefore, to address the key problems of existing fireworks inner tube sealing technologies, there is an urgent need for an efficient, stable, and economical sealing agent filling device that balances quality, efficiency, and safety. Utility Model Content

[0003] In view of the problems mentioned above in the background art, the purpose of this utility model is to provide a sealing agent filling device.

[0004] To achieve the above technical objectives, the technical solution adopted by this utility model is as follows:

[0005] A sealing agent filling device includes a frame, a filling hopper is installed on the top of the frame, a metering plate is installed at the bottom output end of the filling hopper, a conveying lifting line is provided on the lower side of the frame, and a tooling tray is slidably installed on the conveying lifting line.

[0006] The filling hopper includes a hopper with a material inlet at the top center. A position sensor is installed on one side of the top of the hopper, with the sensing end of the position sensor located inside the hopper. Fixed brackets are installed on both sides of the bottom of the hopper, and the fixed brackets are fixedly installed on the top of the frame.

[0007] The quantitative medicine plate includes an assembly plate mounted on a frame. A telescopic cylinder is installed at the bottom of the assembly plate. A locking cylinder is connected to the power output end of the telescopic cylinder. A pneumatic gripper is connected to the power output end of the locking cylinder. An intermediate drawer plate is connected to the output end of the pneumatic gripper. An upper medicine loading plate and a lower medicine delivery plate are provided on the upper and lower sides of the intermediate drawer plate. Both the upper medicine loading plate and the lower medicine delivery plate are installed inside the fixed bracket and located directly below the output end of the medicine hopper. Both the upper medicine loading plate and the lower medicine delivery plate are provided with corresponding through holes. Several corresponding holes are provided on the intermediate drawer plate.

[0008] Furthermore, linear sliders are installed on both sides of the bottom of the assembly plate, and the locking cylinder is fixedly mounted on the linear sliders. This structural design ensures that the locking cylinder moves smoothly along the linear sliders.

[0009] Furthermore, the intermediate drawer plate has a fixing groove on one side corresponding to the pneumatic gripper, and the pneumatic gripper clamps itself within the fixing groove. This structural design facilitates the pneumatic gripper clamping the fixing groove of the intermediate drawer plate, allowing the intermediate drawer plate to move.

[0010] Furthermore, the conveying and lifting line includes a conveyor line located inside the lower side of the frame, with a lifting device installed directly below the metering tablet on the conveyor line, and a blocking device installed on one side of the lifting device on the conveyor line. This structural design ensures stable conveying of the tooling pallet and facilitates the lifting and loading of the medication.

[0011] Further specifying, the tooling tray includes a tooling plate slidably disposed within the conveyor line, a limiting tray mounted on the top of the tooling plate, and a plurality of cartridges installed within the limiting tray. This structural design facilitates the layout and installation of the cartridges, thereby enabling subsequent loading.

[0012] The beneficial effects of this utility model are as follows: By setting up a filling hopper, this utility model can monitor the remaining amount of sealing agent in the hopper in real time and accurately control the total feeding amount. Through the closed hopper and automated filling process, it reduces the direct contact between workers and the chemicals in the sealing agent, thereby reducing the risk of occupational diseases from the source. The quantitative medicine plate adopts a hole matching structure of upper filling plate, middle drawing plate and lower feeding plate. The hole positions are staggered and aligned by the sliding of the drawing plate driven by the cylinder, which strictly controls the dosage of each filling and solves the problem of "uneven dosage and inconsistent product performance" in manual operation, which greatly improves the product yield. The whole set of equipment integrates the conveying and lifting line, tooling tray and quantitative filling mechanism. From the addition of sealing agent, the conveying of medicine cylinder, positioning and lifting, to quantitative filling and finished product conveying, the whole process is completed automatically without human intervention. Compared with the inefficiency of manual filling and the intermittent operation mode of some mechanized equipment, this equipment can realize large-scale continuous production, significantly improve the unit time capacity, and meet the needs of batch production.

[0026] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] Example 1, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a sealing agent filling device has a filling hopper 1 installed on the top of the frame 5, a metering plate 2 installed at the bottom output end of the filling hopper 1, a conveying lifting line 3 provided on the lower side of the frame 5, and a tooling tray 4 slidably installed on the conveying lifting line 3.

[0028] The filling hopper 1 includes a hopper 11. The top center of the hopper 11 is provided with a material inlet 14. A position sensor 12 is installed on one side of the top of the hopper 11. The sensing end of the position sensor 12 is located inside the hopper 11. Fixed brackets 13 are installed on both sides of the bottom of the hopper 11. The fixed brackets 13 are fixedly installed on the top of the frame 5.

[0029] The quantitative medicine plate 2 includes an assembly plate 27 mounted on the frame 5. A telescopic cylinder 24 is installed at the bottom of the assembly plate 27. A locking cylinder 25 is connected to the power output end of the telescopic cylinder 24. A pneumatic gripper 26 is connected to the power output end of the locking cylinder 25. An intermediate draw plate 22 is connected to the output end of the pneumatic gripper 26. An upper medicine loading plate 21 and a lower medicine delivery plate 23 are provided on the upper and lower sides of the intermediate draw plate 22. Both the upper medicine loading plate 21 and the lower medicine delivery plate 23 are installed inside the fixed bracket 13 and located directly below the output end of the medicine hopper 11. Both the upper medicine loading plate 21 and the lower medicine delivery plate 23 are provided with corresponding through holes 28. Several corresponding holes 29 are provided on the intermediate draw plate 22.

[0030] In this embodiment, during use, the filling hopper 1 is first filled with material. Sealing agent is added to the hopper 11 through the material inlet 14. The position sensor 12 is used to detect the amount of sealing agent fed. Once the specified dosage is reached, the sealing agent feeding stops. Then, the conveying lifting line 3 moves the tooling tray 4 to the lower side of the quantitative medicine plate 2. The conveying lifting line 3 pushes the tooling tray 4 upward so that it mates with the through hole 28 of the lower medicine plate 23. Then, the telescopic cylinder 24 is activated. The telescopic cylinder 24 moves the locking cylinder 25, and the locking cylinder 25 moves the pneumatic gripper 26 to clamp the intermediate drawer. When plate 22 moves, in the initial position, the corresponding hole 29 in the middle of the middle drawer plate 22 is misaligned with the through hole 28 of the upper medicine loading plate 21 and the lower medicine delivery plate 23. After the medicine hopper 11 is filled, the locking cylinder 25 clamps the drawer plate 22. When the telescopic cylinder 24 pushes the upper medicine loading plate 21, the lower medicine delivery plate 23 and the middle drawer plate 22, the through hole 28 is aligned with the corresponding hole 29, the sealing agent falls into the tooling tray 4. After the medicine is filled, the conveying lifting line 3 drives the tooling tray 4 to descend. The tooling tray 4 carries the medicine cartridge that has been filled along the conveying lifting line 3 to the subsequent work station.

[0031] Example 2, as Figure 3 and Figure 4 As shown, this embodiment adds the following structure to the embodiment 1: linear sliders 210 are installed on both sides of the bottom of the assembly plate 27, and locking cylinders 25 are fixedly installed on the linear sliders 210.

[0032] In this embodiment, during use, by setting a linear slider 210, the telescopic cylinder 24 drives the locking cylinder 25 to move along the linear slider 210 for guidance.

[0033] Example 3, as Figure 3 and Figure 4 As shown, this embodiment adds the following structure based on embodiment 1: the intermediate draw plate 22 is provided with a fixing groove 211 on one side of the corresponding pneumatic gripper 26, and the pneumatic gripper 26 is clamped in the fixing groove 211.

[0034] In this embodiment, by setting a fixing groove 211, the locking cylinder 25 drives the pneumatic gripper 26 to clamp the fixing groove 211 of the intermediate drawer plate 22, so that the intermediate drawer plate 22 can move.

[0035] Example 4, as Figure 1 and Figure 5 As shown, this embodiment adds the following structure to embodiment 1: the conveying lifting line 3 includes a conveying line 31 located inside the lower side of the frame 5, a lifting device 33 installed directly below the metering plate 2 on the conveying line 31, and a blocking device 32 installed on one side of the lifting device 33 on the conveying line 31. This structural design provides stable conveying of the tooling tray 4 and facilitates the lifting and loading of the medicine.

[0036] In this embodiment, during use, the tooling tray 4 carries the inner cylinder to be filled along the conveyor line 31. During operation, the blocking device 32 is installed at a specific position on the conveyor line 31, limiting the tooling tray 4 to the hole alignment position directly below the quantitative medicine plate 2. The lifting device 33 is installed at a fixed position below the conveyor line 31. During operation, it lifts the tooling tray 4 so that it matches the corresponding hole of the lower medicine plate 23 to achieve precise positioning. After the medicine is filled, the lifting device 33 descends, the blocking device 32 retracts, and the tooling tray 4 carries the filled medicine cylinder along the conveyor line 31 to the subsequent work station.

[0037] Example 5, as Figure 1 and Figure 6 As shown, this embodiment adds the following structure based on embodiment 1: the tooling tray 4 includes a tooling plate 43 that is slidably disposed in the conveyor line 31, a limiting tray 42 is installed on the top of the tooling plate 43, and a plurality of cartridges 41 are installed in the limiting tray 42.

[0038] In this embodiment, during installation, the cartridge 41 is placed vertically above the limiting tray 42, the limiting tray 42 is installed on the tooling plate 43, and the tooling plate 43 moves along the conveyor line 31.

[0039] The tooling plate 43 has pin holes around its perimeter, which are used to limit the movement of the tooling plate 43 by engaging with the pins of the lifting device 33.
