Description

Technical Field

[0001] The utility model relates to an integrated machine for manufacturing and screening fireworks pellets. Background Art

[0002] CN 204897774 U, an automatic granulator for fireworks pellets, and CN 105066792 B, an automatic production line and process for forming fireworks pellets, disclose automatic granulating devices for fireworks pellets. However, in the granulating process of the automatic granulator for pellets, the granulating disc of the granulator is driven by a robotic arm to rotate vertically, so as to switch between the feeding station, the granulating station and the discharging station, and a belt is used to transport raw materials and pellets. In the actual operation process, since the granulating disc is open, with a large volume and heavy mass, it is inaccurate to transfer the granulated pellets to the discharging transport belt by dumping the disc with a robotic arm, and accidents are likely to occur. Therefore, in the actual production process, the granulated pellets are still manually transported from the disc; in addition, the screening plates or screening boxes of the pellet screening equipment are arranged in multiple layers from top to bottom. Since the pellets are flammable and explosive, there are safety hazards when the pellets fall layer by layer from top to bottom. The discharge ports provided in each layer are connected to the transport belt, the discharging is inaccurate, and the screening effect is not ideal. The screening plates or screening boxes are arranged vertically in multiple layers, and it is inconvenient to disassemble and clean the sieve meshes. Content of the Utility Model

[0028] Next, the technical solutions in Embodiment 1 of the present utility model will be clearly and completely described in conjunction with the attached drawings in Embodiment 1 of the present utility model. Figures 1-5 Specifically, a screening and integrating machine for manufacturing fireworks bright beads according to the present utility model includes a feeding device 200, a granulating device 300, and a bright bead screening device 400.

[0029] Refer to Figure 1 Specifically, a screening and integrating machine for manufacturing fireworks bright beads according to the present utility model includes a feeding device 200, a granulating device 300, and a bright bead screening device 400.

[0030] Refer to Figure 1 , Figure 2 , the feeding device 200 includes a first hopper 201, a second hopper 202, and a feeding assembly installed on the frame 100; the feeding assembly includes a base 203, a lifting guide rail 204, a moving frame 205 movably connected to the lifting guide rail 204, and a third driving member motor 206 drives the moving frame 205 to move in the vertical direction of the lifting guide rail. Two support rods 207 of the base 203 are hinged and fixed to the upper part of the moving frame 205; a cross bar 208 is provided between the two support rods 207, the cross bar 208 is vertically connected to the two support rods 207, a fourth driving device cylinder 209 is fixed on the moving frame 205, and the piston rod of the cylinder 209 is connected to the cross bar 208, and the rotation of the base 203 is realized by the telescopic movement of the piston rod. The piston rod of the cylinder 209 can also be directly connected to other positions of the base 203.

[0031] The base 203 is provided with a gripper and a gripper driving cylinder. The barrel 210 is placed on the base 203, and the gripper clamps the barrel 210 under the action of the gripper driving cylinder to prevent the barrel 210 from shifting.

[0032] The head of the second hopper 202 is fixed on the lifting guide rail 204, and the tail is connected to the first hopper 201; a feeding valve is opened at the feeding port of the first hopper 201, and a nozzle, a nozzle driving cylinder, a scraper, and a scraper driving cylinder are provided at the feeding end of the first hopper 201.

[0033] Refer to Figure 1 , Figure 3, the granulating device 300 includes a rotating shaft 301 of a first driving device movably fixed on the frame 100 through a bearing block and a first driving member motor 303. One end of the rotating shaft 301 is connected to the granulating tank 302 through a bolt-fixed bracket 304, and the other end of the rotating shaft 301 is connected to the output shaft of the first driving member motor 303. The motor 303 drives the rotating shaft 301 to rotate, thereby driving the granulating tank 302 to rotate.

[0034] A material discharge port 305 is formed on the outer wall of the granulating tank 302. A valve and a valve locking assembly are arranged at the material discharge port 305. The valve locking assembly includes a movable plate 307, a spring 308, and a fifth driving device cylinder 309. The valve door panel 306 is fixed to one side of the material discharge port 305 through a door shaft. The door panel 306 is used to close or open the material discharge port. A movable plate 307 is arranged on the other side of the material discharge port 305. One end of the movable plate 307 is fixed to the outer wall of the granulating tank 302 through a spring 308. The movable plate 307 contacts the door panel 306. A fifth driving device cylinder 309 is arranged below the movable plate 307. The fifth driving device cylinder 309 is electrically connected to the main controller of the fireworks bright bead manufacturing and screening integrated machine. The fifth driving device cylinder 309 disconnects from the valve to open the valve.

[0035] As another specific embodiment, the valve of the material discharge port 305 can also be a flap valve or a butterfly valve, etc. The locking assembly of the valve can be a buckle, an electromagnet, or other structures that can realize the function of closing or opening the material discharge port 305 of the valve. In the embodiment, the valve of the material discharge port 305 is a hinge door panel 306. As other embodiments, it can also be set as a track-type door panel. The track-type door panel is installed on the granulating tank 302 through a track. A driving device for driving the door panel to move on the track needs to be correspondingly set. The driving device can be electromagnetic movement or mechanical movement. At the same time, a locking assembly for locking the door panel when it closes the material discharge port 305 should also be set. The locking assembly of the door panel can be a buckle, an electromagnet, or other structures that can realize the function of closing or opening the material discharge port 305 of the valve.

[0036] When the granulating tank 302 does not start discharging materials, the door panel 306 of the material discharge port 305 is tightly closed to close the material discharge port 305. Specifically in this embodiment, since the granulating tank 302 is circular, both the material discharge port 305 and the door panel 306 for closing the material discharge port 305 have a curvature. Since one end of the movable plate 307 is fixed to the outer wall of the granulating tank 302 through a spring 308, the movable plate 307 is closely attached to the door panel 306. A triangle is formed among the movable plate 307, the spring 308, and the granulating tank 302. The triangular supporting force causes the movable plate 307 to have a supporting force on the door panel 306 to close the material discharge port 305.

[0037] When starting the material feeding, the cylinder 309 of the fifth driving device drives the connection point of the movable plate 307 and the spring 308 to move towards the direction of the granulation tank 302. The spring 308 contracts, and the movable plate 307 pops out as a whole in the direction away from the granulation tank 302 with the connection point with the spring 308 as the fulcrum, disconnecting the contact with the door plate 306, and the door plate 306 is opened to complete the material feeding.

[0038] An induction sheet (not shown in the figure) is provided on the outer wall of the granulation tank 302, and a proximity switch (not shown in the figure) is arranged at a position of the frame 100 close to the granulation tank 302. The induction sheet is a metal sheet, specifically an induction iron. The installation position of the induction sheet on the granulation tank 302 is specifically determined according to the installation position of the proximity switch, that is, the induction sheet should be installed within the induction area of the proximity switch. When the induction sheet rotates with the outer wall of the granulation tank 302 to the electromagnetic induction area of the proximity switch, the proximity switch provides the position and stroke of the granulation tank 302 to the main controller, and the main controller issues an instruction to stop the rotation of the granulation tank 302.

[0039] The granulation tank 302 is installed below the first hopper 201 of the feeding device 200, and the feeding end of the first hopper 201 extends into the opening of the granulation tank 302.

[0040] Refer to Figure 1 、 Figure 4 , the bright bead screening device 400 includes a vibrating screen 401 composed of a screen plate 402 and a housing 403. The housing 403 is separated into a plurality of cavities 405 by a partition plate 404. The number of cavities can be set to 2, 3, 4, or more according to the requirements of the bright beads. In this embodiment, the number of cavities is four. Support bars (not shown in the figure) are provided on the inner wall of each cavity 405, and the four screen plates 402 are respectively placed in each cavity 405 through the support bars, separating the cavity 405 into upper and lower layers, and the upper layer of the cavity 405 contains bright beads. The screen hole diameters of the screen plates 402 in the four cavities are different, and the cavity 405 is sequentially separated into a fine particle area 51, a small particle area 52, a standard particle area 53, and a large particle area 54 from small to large. One side of the fine particle area 51 is connected to a feeding tray 406, and the feeding tray 406 is arranged below the granulation tank 302 of the granulation device 300.

[0041] The regulating door 407 is fixed to the connection between the feeding tray 406 and the fine particle area 51 through a door hinge. The regulating door 407 is connected to a swinging cylinder (not shown in the figure), and the swinging cylinder is connected to the main controller. The regulating door 407 is opened and closed through the swinging cylinder to control the feeding. A discharge port 408 is provided at the lower layer position of the housing 403 corresponding to each cavity 405. The sieve plate 402 can also be set as an integral sieve plate. Correspondingly, the sieve holes of the integral sieve plate are set according to different requirements for the particle sizes of each particle area. The vibrating sieve 401 can also be not provided with the feeding tray 406. After the granulation is completed, the bright beads directly fall from the discharge port of the granulation tank 302 onto the sieve plate 402 of the cavity and sequentially complete the screening of the bright beads.

[0042] Refer to Figure 5 , support rods are respectively arranged at the four top corner positions of the bottom of the housing 403 and are hinged to the frame 100 through bolts to form movable points 409. The number of movable points 409 is set to 2, 3 or more. A fixed shaft 410 is arranged at the bottom of the housing 403. One end of the connecting rod 411 is connected to the fixed shaft 410, and the other end is connected to the eccentric shaft 412. The eccentric shaft 412 is fixed to the frame 100 and is connected to the drive shaft of the second driving member, the hydraulic motor 413. The hydraulic motor 413 is connected to the main controller. When the hydraulic motor 413 is started, the eccentric shaft 412 makes a reciprocating motion driven by the hydraulic motor 413, and the housing 403 vibrates following the reciprocating motion of the eccentric shaft 412 under the traction of the connecting rod 411.

[0043] When the integrated machine for manufacturing and screening fireworks bright beads is started, the operator puts the materials required for manufacturing bright beads into the material cylinder 210. The third driving member, the motor 206, drives the moving frame 205 to move upward in the vertical direction along the lifting guide rail 204. When the base 203 rises with the moving frame 205 to a predetermined position, the fourth driving device, the cylinder 209, is started. The piston rod of the cylinder 209 pushes the cross bar 208 upward. Since the two support rods 207 of the base 203 are hinged and fixed to the upper part of the moving frame 205, the base 203 rotates upward as a whole under the push of the cylinder 209. When the moving frame 205 moves to the top end of the lifting guide rail 204, the base 203 continues to move towards the second hopper 202, and the materials in the material cylinder 210 are injected into the second hopper 202. The grippers on the base 203 clamp the material cylinder 210 under the drive of the gripper driving cylinder to prevent the material cylinder 210 from shifting during the process of pouring materials. The materials are injected into the first hopper 201 through the second hopper 202 and are injected into the granulation tank 302 through the discharge port of the first hopper 201. The discharge valve opened at the discharge port of the first hopper 201 is opened and closed according to the instruction to control the discharging.

[0044] The first driving motor 303 drives the rotating shaft 301 to rotate, and then drives the granulating tank 302 to rotate. The material is granulated during the rotation of the granulating tank 302. The discharge end of the first hopper 201 is provided with a nozzle, and the nozzle driving cylinder opens the nozzle according to the instruction to spray the alcohol or other preparations required for granulation; the scraper and the scraper driving cylinder open the scraper according to the instruction to scrape off the material attached to the granulating tank 302 to prevent material deposition.

[0045] After granulation is completed, the main controller issues a command, the rotation speed of the granulation tank 302 is reduced, and the proximity switch is activated. When the proximity switch senses the inductive iron on the outer wall of the granulation tank 302, the proximity switch transmits the movement position of the granulation tank 302 to the main controller, and the main controller issues a command, the granulation tank 302 stops rotating, and the discharge port 305 stops above the feed tray 406 of the vibrating screen 401. The fifth drive device cylinder 309 is activated, and the piston rod of the cylinder 309 moves upward to support the connection between the movable plate 307 and the spring 308. The spring 308 is compressed to drive one end of the movable plate 307 to move upward. The movable plate 307 moves as a whole away from the granulation tank 302 with the connection between the movable plate 307 and the spring 308 as the fulcrum, and breaks the contact with the door plate 306. After the door plate 306 leaves the support of the movable plate 307, it opens itself and the beads in the granulation tank 302 are bright. The bright beads fall freely from the feed port 305 into the feed tray 406 of the bright bead screening device 400 below under the action of gravity. The second driving member hydraulic motor 413 is started, and the housing 403 and the feed tray 406 vibrate in a wave-like manner under the action of the eccentric shaft 412 and the connecting rod 411. At the same time, the main controller controls the swing cylinder to open the regulating door 407, and the opening and closing of the regulating door 407 controls the number of bright beads sent from the feed tray 406 to the sieve plate 402. The bright beads roll from the feed tray 406 onto the sieve plate 402, and the bright beads pass through the fine particle area 51, small particle area 52, standard particle area 53 and large particle area 54 of the sieve plate 402 in sequence with the vibration of the housing 403.

[0046] The sieve hole particle size of the sieve plate 402 on the fine particle area 51 is the smallest, and the bright beads with a particle size less than or equal to the particle size of the sieve hole of the fine particle area 51 fall from the sieve hole into the lower layer of the cavity 405, and the bright beads with a particle size greater than the particle size of the sieve hole of the fine particle area 51 move to the small particle area 52 with the vibration of the shell 403, and so on, the bright beads of different particle sizes pass through the sieve holes on the sieve plate 402 in sequence and fall into the cavities 5 of the small particle area 52, the standard particle area 53 and the large particle area 54. Because the lower material cavity of each particle area is independently separated, the bright beads of different particle sizes fall into the lower material cavity and are output through each discharge port 408, and the bright beads of different particle sizes are transported through the barrel set below each discharge port 408.

[0047] It should be noted that all directional indications (such as horizontal direction, vertical direction, parallel setting, perpendicular setting, up, down, left, right, front, back...) in the embodiments of the present utility model are only used to explain the relative positional relationship, movement conditions, etc. between components in a certain specific posture (as shown in the attached drawings). If this specific posture changes, then the directional indication also changes accordingly.

For example, "connection" can be a fixed connection, a detachable connection or an integral one, can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and can be the communication inside two elements or the interaction relationship between two elements. The driving device is not limited to a motor, a hydraulic motor, a pneumatic motor, etc. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
