Description

Technical Field

[0001] The utility model relates to the field of firecracker processing, in particular to a precise feeding device based on firecracker production. Background Art

[0002] Firecrackers are one of the Chinese folk cultures. After being ignited, firecrackers burn or explode to produce light, sound, color, shape, smoke and other effects. They are used for viewing. They are flammable and explosive dangerous items. They are widely welcomed by people due to their high ornamental value. Firecrackers are made of paper tubes, which are made by adding gunpowder to the paper tubes, inserting primers and packaging. At present, filling gunpowder into firecracker paper tubes is still mainly done by manual work. When filling gunpowder, the problem of gunpowder scattering will occur, causing gunpowder to diffuse in the air, affecting the working environment. In addition, the waste of gunpowder and the extra cost of safety assurance also greatly increase the pressure on product cost. Utility Model Content

[0003] In order to overcome the problem of gunpowder scattering when filling gunpowder, causing gunpowder to diffuse in the air and affect the working environment, and the waste of gunpowder and the extra cost of safety assurance also greatly increase the cost pressure of products, the purpose of the utility model is to provide a precise feeding device based on firecracker production.

[0004] The technical solution is: a precise feeding device based on firecracker production, including a shell, a discharge pipe fixedly connected to one side of the shell, a discharge barrel fixedly connected to the other side of the shell, a cover plate rotatably connected to the top of the discharge barrel, a disc rotatably connected inside the shell, the discharge pipe and the bottom of the discharge barrel are in contact with the disc, the disc is provided with discharge ports equidistantly distributed in the circumferential direction, a transmission disc is fixedly connected to the disc, a first motor is fixedly connected to the inside of the shell, a turntable is fixedly connected to the output shaft of the first motor, and bumps are fixedly connected to both ends of the turntable.

[0005] As an improvement of the above solution, a notch corresponding to the discharge port is provided on the transmission disc, and the protrusion is engaged with the notch on the transmission disc.

[0006] As an improvement of the above solution, a tray is also included. The tray is slidably connected to each discharge port. A top rod is fixedly connected to the bottom of each tray, and a guide block is fixedly connected to the center of the top of the turntable.

[0007] As an improvement of the above solution, the push rod is L-shaped, and the bottom of the push rod is in contact with the guide block.

[0008] As an improvement to the above solution, the portion of the guide block that contacts the ejector rod is in the shape of a threaded blade.

[0009] As an improvement of the above scheme, a second motor is also included. The second motor is fixed to the top center of the discharge barrel. The top center of the discharge barrel is rotatably connected to a stirring frame, and the end of the stirring frame is fixed to the output shaft of the second motor.

[0010] The utility model has the following advantages: 1. The circumferential clearance movement of the disc is realized by the contact and cooperation between the protrusion and the transmission disc. When the disc rotates counterclockwise, the discharge port connected with the discharge pipe and the discharge barrel is replaced. When the disc stops, the discharge pipe replenishes the firecracker paper tube in the discharge port, and the discharge barrel fills the gunpowder in the firecracker paper tube in the discharge port, so that continuous and accurate feeding is realized. Since the bottom of the discharge pipe and the discharge barrel is always in contact with the top of the disc, the gunpowder and the firecracker paper tube will not fall out of the discharge port.

[0011] 2. The loaded firecrackers are pushed out through the tray, so that it is convenient for workers to take out the loaded firecrackers;

[0012] 3. Stir the gunpowder in the barrel through the stirring rack to break up the agglomerated gunpowder and avoid blockage. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Embodiment 1: A precise feeding device based on firecracker production, referring to Figure 1 , Figure 2 , Figure 3 and Figure 4, including a shell 1, a discharge pipe 2 is fixedly connected to the right side of the shell 1, a discharge barrel 3 is fixedly connected to the left side of the shell 1, a cover plate 31 is rotatably connected to the top of the discharge barrel 3, a disc 4 is rotatably connected inside the shell 1, the discharge pipe 2 and the bottom of the discharge barrel 3 are in contact with the top of the disc 4, the disc 4 is provided with discharge ports 45 distributed at equal intervals in the circumferential direction, a transmission disk 41 is fixedly connected to the lower part of the disc 4, a first motor 42 is fixedly connected to the inside of the shell 1, a turntable 43 is fixedly connected to the output shaft of the first motor 42, protrusions 44 are fixedly connected to both ends of the turntable 43, a notch corresponding to the discharge port 45 is provided on the transmission disk 41, and the protrusion 44 is fitted with the notch on the transmission disk 41.

[0020] When in use, put the firecracker paper tube into the discharge pipe 2, so that the firecracker paper tube is arranged vertically in the discharge pipe 2, and the firecracker paper tube at the bottom falls into the discharge port communicated with the discharge pipe 2, and the first motor 42 is started. The output shaft of the first motor 42 drives the turntable 43 to rotate clockwise, and the turntable 43 drives the protrusion 44 to rotate clockwise. Since the transmission disk 41 is provided with a notch corresponding to the discharge port 45, and the protrusion 44 is engaged with the notch on the transmission disk 41, when the protrusion 44 is inserted into the notch on the transmission disk 41, the protrusion 44 drives the transmission disk 41 to rotate counterclockwise, and the transmission disk 41 drives the disc 4 to rotate counterclockwise. When the protrusion 44 and the transmission disk 45 are engaged, the protrusion 44 drives the disc 4 to rotate counterclockwise. When the disc 4 is separated, the transmission disc 41 and the disc 4 stop rotating counterclockwise, so that the disc 4 can move in the circumferential gap. When the disc 4 rotates counterclockwise, the discharge port 45 connected with the discharge pipe 2 and the discharge barrel 3 is replaced. When the disc 4 stops rotating counterclockwise, the discharge pipe 2 replenishes the firecracker paper tube in the discharge port 45, and the discharge barrel 3 fills the firecracker paper tube in the discharge port 45 with gunpowder, so that continuous and accurate feeding is achieved. It should be noted that when the discharge port 45 equipped with the firecracker paper tube is connected with the discharge barrel 3, the gunpowder is loaded into the discharge barrel 3, and the cover plate 31 provided on the discharge barrel 3 can prevent the gunpowder in the discharge barrel 3 from flying out.

The push rod 51 is L-shaped, and the bottom of the push rod 51 is in contact with the guide block 52, and the part of the guide block 52 that contacts the push rod 51 is in the shape of a threaded blade.

[0022] When the turntable 43 rotates, the turntable 43 drives the guide block 52 to rotate. When the guide block 52 contacts the bottom of the push rod 51, the guide block 52 pushes the push rod 51 to move upward. The push rod 51 drives the tray 5 to move upward. The tray 5 pushes out the loaded firecrackers, thereby making it convenient for workers to take out the loaded firecrackers. When the guide block 52 is separated from the push rod 51, the push rod 51 and the tray 5 move downward and reset due to their own gravity.
