Description

Technical Field

[0001] The invention relates to a fireworks production device, in particular to a fireworks powder bead manufacturing machine. Background Art

[0002] At present, there are some problems with the pyrotechnic bead making machine. First, the drug is directly poured into the bead tank. Due to the agglomeration of the drug itself, the bead formation time is long and the size of the beads is different. Secondly, the droplets flowing out of the humidification device are large, and the humidification device is always above the bead tank when it is not working. The humidification device works for a long time and it is inevitable to leak, which causes uneven humidity of the beads. Thirdly, the feeding device of the pyrotechnic bead making machine generally uses a belt conveyor, which occupies a large space, pollutes the environment, and has safety hazards. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the present invention provides a pyrotechnic powder bead manufacturing machine which has a simple structure and is safe and reliable.

[0004] The present invention adopts the following technical scheme.

[0005] A pyrotechnic powder bead manufacturing machine comprises a frame, a powder bead tank and a transmission device, as well as a feeder, a feeding device and a humidifying device. The feeder is located above the powder bead tank, and has a shell with an opening at the lower end. The shell has a material throwing disc, and the material throwing disc has at least one protrusion. The side of the protrusion is a plane or a curved surface. The material throwing disc is connected to a rotating mechanism or a swinging mechanism. The side or top of the shell is connected to the feeding device. The feeder is connected to a reciprocating mechanism or a swinging mechanism. The feeding device has a shell, and the upper end of the shell is connected to a vacuum pump or a vacuum generator. The shell has a filter. The side of the shell below the filter has a feed port connected to a pipe, and the pipe is inserted into a material holding barrel. The humidifying device has a spray head, and the spray head is connected to a gas pressure tank filled with water or alcohol through a pipe and a humidifying valve, and the spray head is connected to the reciprocating mechanism or the swinging mechanism.

[0006] The number of the protrusions is a number between 2 and 6.

[0007] The side surface of the protrusion is a hyperbolic paraboloid.

[0008] Compared with the prior art, the invention has the advantages of uniform feeding dispersion, improved product quality and quantity, reduced equipment volume, and eliminated some potential safety hazards. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 2 This is a schematic structural diagram of the material-removing disc and the protrusions in Example 1 of the present invention.

[0011] Figure 3 It is a schematic structural diagram of the material-removing disc and the protrusions in Example 2 of the present invention. DETAILED DESCRIPTION

[0012] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0013] Embodiment 1, as Figure 1-2 As shown, a pyrotechnic powder bead manufacturing machine has a bead pot 12, which is connected to a transmission device (not shown in the figure), which is fixed on a frame (not shown in the figure), and a feeder is arranged above the bead pot 12, and the feeder has a shell 3 with an opening at the lower end, and a material throwing disc 11 is arranged in the shell 3, and there are four protrusions 10 on the material throwing disc 11, and the side 9 of the protrusion 10 is flat, and the material throwing disc 11 is connected to the shaft of a rotating cylinder 8 fixed on the shell 3, and the upper side of the shell 3 is connected to the feeding device. The feeding device has a shell 7, and the upper end of the shell 7 is connected to a vacuum pump (not shown in the figure) through a connecting pipe 6, and a filter 5 is arranged in the shell 7, and a feed port is arranged on the side of the shell 7 below the filter 5, and the feed port is connected to a feed pipe 4, and the feed pipe 4 is inserted into a material storage barrel (not shown in the figure), and the lower end of the shell 7 is connected to the feeder. The feeder is fixed to the piston rod of the feed cylinder 13, and the cylinder body of the feed cylinder 13 is fixed on the frame (not shown in the figure). The humidifying device has a spray head 2, which is connected to a gas pressure tank containing alcohol (not shown in the figure) through a pipeline and a humidifying valve. The spray head 2 is fixed to the piston rod of the humidifying cylinder 1, and the cylinder body of the humidifying cylinder 1 is fixed on the frame (not shown in the figure). When the pyrotechnic bead manufacturing machine starts working, the transmission device rotates the pharmaceutical bead tank 12, and the controller (not shown in the figure) extends the piston rod of the feed cylinder 13. The feeder is located above the pharmaceutical bead tank 12, and the rotating cylinder 8 drives the material throwing disc 11 to rotate 180 degrees alternately, and then rotates 180 degrees in the opposite direction. The vacuum pump is started, and the medicine in the material barrel is sucked into the feeding device housing 7 through the feed pipe 4. The air enters the vacuum pump through the filter 5, and the medicine is blocked by the filter 5 and falls onto the material throwing disc 11. , and then thrown onto the inner wall of the shell 3 by the throwing disc 11 and the protrusion 10 to be broken up, and fall into the pharmaceutical bead tank 12 from the gap between the throwing disc 11 and the inner wall of the shell 3. At the same time, the piston rod of the humidifying cylinder 1 is extended, and the spray head 2 is located above the pharmaceutical bead tank 12. The humidifying valve is opened to spray and humidify the medicine in the pharmaceutical bead tank 12. After the feeding and humidifying process is completed, the piston rod of the feeding cylinder 13 and the piston rod of the humidifying cylinder 1 are retracted, and the feeder and the spray head 2 leave the top of the pharmaceutical bead tank 12.

[0014] In Example 2, except that the side surface of the projection 10 is a hyperbolic paraboloid (such as Figure 3The other parts are the same as those in Example 1. Experiments show that when the side surface 14 of the projection 10 is a hyperbolic paraboloid, the time for making the pyrotechnic powder beads can be shortened by about 5%, and the uniformity of the size of the powder beads can be improved by about 3%.
