AI Technical Summary
In the production of fireworks charging, the gap between the charging template and the movable base plate causes the charging to leak, affecting the charging accuracy. The friction between the movable base plate and the slide groove may cause combustion and explosion, and the trapped charging dust poses a safety hazard.
A sealed safety unloading device with a charging template is used. A sealing ring and a vacuum pump are set between the movable bottom plate and the slide to suck in drug dust to ensure that the drug does not leak out of the holes. A drug safety processor is used to handle the dust to prevent fire and explosion caused by friction.
It improves the charging accuracy, prevents drug holes and combustion and explosion, eliminates safety hazards and ensures production safety.

Abstract
Description
Technical Field
[0001] The invention relates to fireworks production equipment, in particular to a charge template sealed safety unloading device. Background Art
[0002] In current fireworks production, there's a gap between the charge template and the underlying movable baseplate. This creates the possibility that charge from one metering hole could slip through the gap into an adjacent metering hole, affecting charge accuracy. Furthermore, any charge trapped between the movable baseplate and the charge template, or between the movable baseplate and the chute, can ignite and explode due to frictional heat or static electricity generated by friction when the movable baseplate is pulled to unload. Furthermore, dust from this trapped charge floats in the air, posing a safety hazard. Summary of the Invention
[0003] In order to overcome the deficiencies of the prior art, the present invention provides a charging template sealed safety unloading device with a simple structure.
[0004] The present invention adopts the following technical solutions.
[0005] A charging template sealed safety unloading device comprises a charging template, a movable bottom plate and a medicine hopper. The charging template is installed on a frame, has quantitative holes, is surrounded by panels on the top and bottom of the charging template, has two slide grooves fixed under the charging template, the movable bottom plate slides in the slide grooves, the movable bottom plate is fixed to the piston rod of the unloading cylinder fixed to the frame, the medicine hopper is located above the charging template, brushes are fixed around the bottom of the medicine hopper, the medicine hopper is fixed to the piston rod of the loading cylinder fixed on the panels, and each quantitative hole has an annular groove at the lower end, in which a sealing ring is installed.
[0006] There are two drug dust suction ports respectively installed at one end of the two slides. The drug dust suction ports are connected to the inlet of the drug safety processor through a pipe. The vacuum pump is connected to the outlet of the drug safety processor. The drug safety processor is equipped with a screen, a filter cotton device and a bag device.
[0007] Compared with the prior art, the advantages of the present invention are that the medicine in one quantitative hole of the charging template cannot flow into the adjacent quantitative hole, thereby improving the charging accuracy; it is impossible for medicine to be trapped between the movable bottom plate and the charging template, and between the movable bottom plate and the slide groove, thereby preventing the occurrence of drug combustion and explosion accidents; and the drug dust is handled in time, eliminating safety hazards.

[0011] Figure 4 This is a connection diagram of the drug dust suction port, drug safety processor and vacuum pump. Implementation Method
[0012] The present invention is further described in detail below with reference to the accompanying drawings and examples.
[0013] like Figure 1-4 As shown, a charging template sealed safety unloading device has a charging template 5, a movable bottom plate 2 and a medicine hopper 4. The charging template 5 is installed on the frame 9. The charging template 5 has a quantitative hole 6. The charging template 5 is surrounded by a panel 7. Two slide grooves 13 are fixed under the charging template 5. The movable bottom plate 2 slides in the slide groove 13. The movable bottom plate 2 is fixed to one end of the connecting plate 14. The other end of the connecting plate 14 is fixed to the piston rod of the unloading cylinder 1 fixed to the frame 9. The medicine hopper 4 is located above the charging template 5. Brushes 15 are fixed around the bottom of the medicine hopper 4. The medicine hopper 4 is fixed to the two piston rods of the loading cylinder 3 fixed on the panel 7. Each quantitative hole 6 has an annular groove at the lower end, and a sealing ring 12 is installed in the annular groove. The two drug dust suction ports 8 are respectively installed at one end of the two chutes 13. The drug dust suction ports 8 are connected to the inlet of the drug safety processor through a pipe. The vacuum pump 19 is connected to the outlet of the drug safety processor. The drug safety processor is equipped with a screen 16, a filter cotton device 17 and a bag device 18.
[0014] During loading, the movable base plate 2 seals the bottom of the metering holes 6 in the charging template 5. The drug hopper 4, driven by the loading cylinder 3, fills the metering holes 6 with the drug. During unloading, the unloading cylinder 1 aligns the holes 11 on the movable base plate 2 with the corresponding metering holes 6, allowing the drug to flow into the paper tube cake below the movable base plate 2 (not shown). The sealing ring 12 at the lower end of the metering hole is in close contact with the movable base plate 2, ensuring that all the drug in the metering hole 6 flows into the paper tube cake. The vacuum pump 19 is intermittently operated, and the drug dust suction port 8 draws the drug dust into the drug safety processor.
