Description

Technical Field

[0001] The present invention relates to the technical field of machinery and equipment for the production of fireworks and firecrackers, and more specifically to a charging device for circulating medicine receiving, quantitatively dropping and loading fireworks and firecracker medicine. Background Art

[0002] Currently, there is a disclosed patent with publication number CN111811334A and title "A Fireworks and Firecracker Charging Machine". In the charging device, 127 rubber discharge hoses are provided. By ventilating and squeezing the inside of the counterbore to close the rubber discharge hoses, the 127 rubber discharge hoses can be opened and closed simultaneously, thereby realizing synchronous and equal charging of 127 medicine holes of the flower-spraying tube.

[0003] In the specific charging process, the feeding device first adds cold fireworks raw materials into the medicine dividing cylinder, and then drives a scraper through a hydraulic stirring motor to evenly scrape the raw materials into 127 first medicine dividing through holes. Then, the corresponding solenoid valve turns off the high air pressure of the air inlet joint, and the discharge hose opens under the action of its own elasticity. All the gunpowder raw materials in the first medicine dividing through holes fall into the second medicine dividing through holes below, and then fall into the medicine holes of the matching flower-spraying tube.

[0004] However, the above-mentioned charging machine still has some problems to be solved. For example, during charging, it is necessary to fill all 127 first medicine dividing through holes with explosive raw materials before opening the 127 discharge hoses simultaneously to achieve synchronous and equal charging of the 127 medicine holes of the flower-spraying tube, and its charging efficiency is not high. In addition, since high-pressure air needs to be introduced into the counterbore, this poses new challenges to the sealing and safety of the equipment. Moreover, when using this equipment, corresponding high-pressure air equipment must be equipped, resulting in that production enterprises not only need to purchase this charging equipment, but also need to purchase high-pressure air equipment additionally, which obviously also increases the production cost of the enterprise.

[0005] Therefore, how to provide a charging device for circulating medicine receiving, quantitatively dropping and loading fireworks and firecracker medicine with high charging efficiency, without high-pressure gas source and low cost is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0006] In view of this, the present invention provides a charging device for circulating medicine receiving, quantitatively dropping and loading fireworks and firecracker medicine. This device not only has low production cost, but also has high charging efficiency and can be used without a high-pressure gas source, greatly meeting the market demand for high efficiency and low cost in the production of fireworks and firecrackers.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A charging device for circulating medicine receiving, quantitatively dropping and loading fireworks and firecracker medicine, comprising:

[0009] An explosion-proof room, which has a gun barrel shell inlet and a gun barrel shell outlet;

[0010] A conveyor belt is arranged through the inlet and outlet of the barrel shell for conveying the barrel shell, and a plurality of medicine holes are provided on the barrel shell;

[0011] A frame is fixed on the inner wall of the explosion-proof chamber and is located above the conveyor belt, and a feed hopper is fixed on the frame;

[0012] A reduction motor is fixed on the top plate of the frame, and the drive shaft of the reduction motor is arranged downward through the top plate;

[0013] A turntable is located above the conveyor belt. The top end of the turntable is fixedly connected with the drive shaft of the reduction motor through a connecting rod. A plurality of medicine storage trays are embedded on the turntable, and medicine storage holes matching the medicine holes are provided on the medicine storage trays;

[0014] A medicine receiving mechanism is fixed on the bottom end face of the top plate for receiving the explosive raw material of the feed hopper and cyclically filling the medicine storage holes of the plurality of medicine storage trays with the explosive raw material;

[0015] A dropping and loading mechanism is fixed on the frame for cyclically filling the medicine holes of the barrel shells on the conveyor belt with the explosive raw material in the plurality of medicine storage trays filled with the explosive raw material;

[0016] An opening and closing mechanism, which is a plurality of fixed on the bottom end face of the turntable, and the plurality of opening and closing mechanisms are respectively arranged in one-to-one correspondence with the positions of the plurality of medicine storage trays for opening and closing the medicine storage holes, so as to realize charging the medicine holes from the medicine storage holes.

[0017] As can be seen from the above technical solutions, compared with the prior art, the present invention discloses a charging device for circularly receiving medicine and quantitatively dropping and loading fireworks and firecrackers medicine. When working, the reduction motor drives the turntable to rotate, so that the empty medicine storage tray rotates to directly below the medicine receiving mechanism. The quantitative explosive raw materials are put into the medicine receiving mechanism through the feeding hopper. The medicine receiving mechanism fills the explosive raw materials into a plurality of medicine storage holes in the medicine storage tray below. At this time, the opening and closing mechanism located below the medicine storage tray closes the lower orifice of the medicine storage hole to prevent the leakage of the explosive raw materials in the medicine storage hole. Then, the reduction motor drives the turntable to rotate again, and the medicine storage tray filled with explosive raw materials rotates to directly below the dropping and loading mechanism. At this time, the opening and closing mechanism below the medicine storage tray opens the lower orifice of the medicine storage hole, and the next empty medicine storage tray rotates to directly below the medicine receiving mechanism. The quantitative explosive raw materials are put into the medicine receiving mechanism through the feeding hopper again to continue charging the medicine storage tray below it, realizing the charging of the empty medicine storage tray. At the same time, the dropping and loading mechanism fills the explosive raw materials in the medicine storage tray below it into a plurality of medicine holes of the cartridge case conveyed by the conveyor belt through the opened medicine storage holes, realizing the discharging of the full medicine storage tray and the charging of the empty cartridge case. After that, the reduction motor drives the turntable to rotate again, realizing the filling of the empty medicine storage tray, the discharging of the full medicine storage tray, and the filling of the empty cartridge case. This process can be repeated continuously to realize the continuous charging of multiple cartridge cases.

[0018] Therefore, by arranging components such as a conveyor belt, a medicine receiving mechanism, a dropping and loading mechanism, a turntable, a plurality of medicine storage trays and a plurality of opening and closing mechanisms on the charging device, the simultaneous receiving and dropping of explosive raw materials can be realized, and this process realizes rotational cyclic reciprocating work through the turntable, greatly improving the charging efficiency of fireworks and firecrackers medicine. In addition, the above operations are all carried out in the explosion-proof chamber, effectively preventing the secondary explosion or secondary injury caused by accidents during the production of fireworks and firecrackers through the explosion-proof chamber.

[0019] Further, the medicine receiving mechanism includes:

[0020] A scraper motor, which is fixed on the bottom end surface of the top plate, and the drive shaft of the scraper motor is arranged downward;

[0021] A medicine receiving cylinder, which is fixedly connected to the scraper motor through a support rod. The discharge port of the feeding hopper is connected to the upper orifice of the medicine receiving cylinder. The lower orifice of the medicine receiving cylinder contacts the top end surface of the turntable, and the medicine storage tray can be located inside the medicine receiving cylinder;

[0022] A scraper assembly, which is fixed on the drive shaft of the scraper motor and is used to scrape the explosive raw materials in the medicine receiving cylinder into the medicine storage holes on the medicine storage tray.

[0023] The beneficial effects of adopting the above technical solution are as follows: The explosive raw materials are put into the medicine receiving cylinder through the feeding hopper and fall on the medicine storage tray. Then, the scraper motor drives the scraper assembly to rotate, scraping the explosive raw materials into the medicine storage holes, thus realizing the charging of multiple medicine storage holes.

[0024] Furthermore, the scraper assembly includes:

[0025] An installation cylinder, which is sleeved and fixed on the driving shaft of the scraper motor;

[0026] An installation plate, which is fixed on the installation cylinder;

[0027] An arc-shaped scraper, which is detachably installed on the installation plate through screws.

[0028] The beneficial effects of adopting the above technical solution are as follows: Since the scraper is of an arc-shaped structure, when scraping the explosive raw materials, it will not scrape the explosive raw materials away from the outermost medicine storage holes. Furthermore, it can ensure that the explosive raw materials inside the installation cylinder can be evenly and completely scraped into multiple medicine storage holes; and, the severely worn arc-shaped scraper can be replaced at any time.

[0029] Furthermore, the medicine receiving cylinder includes:

[0030] A cylinder body, which is fixedly connected to the scraper motor through the support rod. The discharge port of the feeding hopper is connected to the upper opening of the cylinder body, and the medicine storage tray can be located inside the cylinder body;

[0031] A medicine-blocking friction ring, which is detachably installed on the lower opening of the cylinder body, and the bottom end of the medicine-blocking friction ring contacts the top surface of the turntable.

[0032] The beneficial effects of adopting the above technical solution are as follows: The medicine-blocking friction ring can not only seal the gap between the cylinder body and the turntable, play a role in preventing the explosive raw materials inside the cylinder body from overflowing, always limit the explosive raw materials inside the cylinder body, ensure that the quantitative explosive materials all fall into the medicine storage holes, realize the subsequent quantitative dropping and loading of the medicine holes, but also the medicine-blocking friction ring is a replaceable part. When the medicine-blocking friction ring is severely worn, only the medicine-blocking friction ring needs to be replaced, without replacing the cylinder body, greatly reducing the part maintenance cost.

[0033] Furthermore, the dropping and loading mechanism includes:

[0034] A pressing air cylinder, which is fixed on the frame;

[0035] A pressing plate, the top end of which is fixed on the telescopic end of the pressing air cylinder. A plurality of pressing rods are fixed on the bottom end surface of the pressing plate, and the pressing rods can extend into the medicine storage holes to push out the explosive raw materials inside.

[0036] The beneficial effects of adopting the above technical solution are as follows: After the medicine storage tray fully loaded with explosive raw materials rotates to the lower part of the pressing plate, the opening and closing mechanism operates to open the lower orifice of the medicine storage hole on the medicine storage tray. The pressing cylinder operates to drive the pressing plate to move downward, and the pressing rod on the pressing plate extends into the medicine storage hole to eject the explosive raw materials in the medicine storage hole out of the medicine storage hole, so that the explosive raw materials fall and are loaded into the medicine holes on the lower barrel shell, realizing the charging of the barrel shell.

[0037] Further, each of the opening and closing mechanisms includes:

[0038] An opening and closing blanking tray, which is fixed on the bottom end surface of the turntable and is arranged corresponding to the medicine storage tray for opening and closing the medicine storage hole;

[0039] A material distribution tray, which is fixed on the bottom end surface of the opening and closing blanking tray for receiving the explosive raw materials falling from the medicine storage hole. The material distribution tray is provided with a plurality of medicine distribution holes matching the medicine holes;

[0040] A driving cylinder, which is fixed on the inner wall of the explosion-proof chamber for driving the opening and closing blanking tray to operate so as to realize the opening and closing of the medicine storage hole.

[0041] The beneficial effects of adopting the above technical solution are as follows: During the initial material receiving, the opening and closing blanking tray closes the lower orifice of the medicine storage hole to ensure that when the arc-shaped scraper scrapes the medicine, the medicine storage hole can be charged without external leakage. After the medicine storage tray fully loaded with explosive raw materials rotates to the lower part of the pressing plate, the driving cylinder operates to drive the opening and closing blanking tray to operate, realizing the opening of the lower orifice of the medicine storage hole. The pressing cylinder operates to drive the pressing plate to move downward, and the pressing rod on the pressing plate extends into the medicine storage hole to eject the explosive raw materials in the medicine storage hole out of the medicine storage hole, so that the explosive raw materials fall into the lower medicine distribution holes, and then fall and are loaded into the medicine holes on the lower barrel shell through the medicine distribution holes, realizing the charging of the barrel shell.

[0042] Further, the opening and closing blanking tray includes:

[0043] A frame, which is fixed on the bottom end surface of the turntable and is arranged corresponding to the medicine storage tray. The material distribution tray is fixed on the bottom end surface of the frame;

[0044] Flip-type baffles, which are arranged side by side. The flip-type baffles cover the lower orifices of the corresponding medicine storage holes. The mounting rotating shafts on each flip-type baffle are respectively rotatably installed on the first side beam and the second side beam of the frame, and first rocker arms and second rocker arms are respectively fixed at both ends of each mounting rotating shaft;

[0045] A first connecting rod, which is placed in the first cavity of the first side beam and is hinged to a plurality of the first rocker arms;

[0046] A reset spring, which is placed inside the first cavity. One end of the reset spring is fixedly connected to one side wall of the first cavity, and the other end is fixedly connected to one end of the first connecting rod.

[0047] A second connecting rod, which is placed inside the second cavity of the second side beam. The second connecting rod is hinged to a plurality of the second rocker arms.

[0048] An intermediate connecting rod, which is placed inside the second cavity. One end of the intermediate connecting rod is hinged to the second connecting rod.

[0049] A driving rod, one end of which is hinged to the other end of the intermediate connecting rod. The other end of the driving rod extends out of the second side beam. The telescopic end of the driving cylinder can abut against the other end of the driving rod to drive the flip - type baffle to flip downward, so as to open the medicine storage hole, and then enable the explosive raw material in the medicine storage hole to fall into the medicine hole through the medicine distributing hole.

[0050] The beneficial effects of adopting the above - mentioned technical solution are as follows: When initially receiving materials, the opening - closing blanking plate closes the lower orifice of the medicine storage hole. Specifically, under the action of the reset spring, the flip - type baffle is in a horizontal position and fits to close the lower orifice of the medicine storage hole, ensuring that the medicine storage hole can be charged without leakage when the arc - shaped scraping plate scrapes the medicine. After the medicine storage plate fully loaded with explosive raw materials rotates to below the pressing plate, the driving cylinder acts to push the driving rod. The driving rod drives the second connecting rod to move through the intermediate connecting rod, and then drives the flip - type baffle to flip downward through the second rocker arm, realizing the opening of the lower orifice of the medicine storage hole. The pressing cylinder acts to drive the pressing plate to move downward, and the pressing rod on the pressing plate extends into the medicine storage hole to push out the explosive raw material in the medicine storage hole, so that the explosive raw material falls into the medicine hole on the lower - placed gun barrel shell, realizing the charging of the gun barrel shell. At this time, the first rocker arm drives the first connecting rod to compress or stretch the reset spring under the drive of the installation rotating shaft. After the medicine hole is charged, the driving cylinder no longer pushes the driving rod. Under the action of the reset spring, the flip - type baffle is again in a horizontal position and fits to close the lower orifice of the medicine storage hole for the next charging of the medicine storage hole.

[0051] Further, the medicine distributing hole is a conical hole with a larger upper hole and a smaller lower hole.

[0052] The beneficial effects of adopting the above - mentioned technical solution are: enabling the medicine distributing hole to more easily receive the explosive raw material in the medicine storage hole and realizing the equal charging of multiple medicine holes.

[0053] Further, it further includes: a gun barrel shell lifting mechanism, which includes:

[0054] Lifting cylinders, there are two of them, which are respectively fixed on the frame of the conveyor belt.

[0055] The lifting plate is fixed at the telescopic ends of the two lifting cylinders at both ends. The lifting plate is located between the upper belt and the lower belt of the conveyor belt and is used to lift the cartridge case located on the upper belt so that the cartridge case is docked with the dosing tray.

[0056] The beneficial effects of adopting the above technical solution are as follows: After the cartridge case is transported to the lower part of the dosing tray by the conveyor belt, the lifting cylinder drives the lifting plate to move upward, and then drives the cartridge case to move upward, so that the cartridge case is docked with the dosing tray, thereby reducing the distance between the medicine hole and the dosing hole, facilitating the dropping of medicine, and avoiding the problem that due to the large distance between the medicine hole and the dosing hole, the explosive raw material in the dosing hole is affected by the external wind and cannot all be loaded into the medicine hole.

[0057] Further, the conveyor belt includes:

[0058] The first conveyor belt is used to transport the cartridge case to the lower part of the dosing tray. The first conveyor belt is arranged at the entrance of the cartridge case. The lifting cylinder is fixed on the frame of the first conveyor belt, and the lifting plate is located between the upper belt and the lower belt of the first conveyor belt;

[0059] The second conveyor belt is arranged at the exit of the cartridge case. The starting end of the second conveyor belt is connected to the end of the first conveyor belt;

[0060] The pushing cylinder is fixed at the end of the frame of the first conveyor belt, or the pushing cylinder is fixed on the inner wall of the explosion-proof chamber and is used to push the cartridge case filled with explosive on the first conveyor belt onto the second conveyor belt.

[0061] The beneficial effects of adopting the above technical solution are as follows: The pushing cylinder can push the cartridge case filled with explosive on the first conveyor belt onto the second conveyor belt and move it out of the explosion-proof chamber for processing in the next process.

[0062] Further, it also includes two relatively arranged cartridge case positioning mechanisms, and each cartridge case positioning mechanism includes:

[0063] The positioning cylinder is fixed on the inner wall of the explosion-proof chamber;

[0064] The positioning clamping plate is fixed on the driving end of the positioning cylinder and is used to clamp and position the cartridge case on the first conveyor belt.

[0065] The beneficial effects of adopting the above technical solution are as follows: After the cartridge case is transported to the lower part of the dosing tray by the conveyor belt, the two positioning cylinders act to drive the two positioning clamping plates to clamp and position the cartridge case, so as to make the medicine holes on the cartridge case correspond to the positions of the dosing holes, facilitating the accurate dropping and loading of the explosive raw material in the dosing holes into the medicine holes.
