Description
Technical Field
[0001] This utility model relates to the technical field of fireworks and firecrackers production machinery and equipment, and more specifically to a charging device for the continuous and quantitative loading of fireworks and firecrackers. Background Technology
[0002] Currently, there is a publication number CN111811334A, named a fireworks and firecrackers charging machine. The charging device has 127 rubber unloading hoses built in. By venting and squeezing the bottom hole to close the rubber unloading hoses, the 127 rubber unloading hoses can be opened and closed simultaneously, thereby achieving synchronous and equal charging of the 127 gun holes of the firework tube.
[0003] During the actual charging process, the feeding device first adds the cold fireworks raw material into the dispensing tube. Then, the hydraulic stirring motor drives the scraper to evenly scrape the raw material into the 127 first dispensing holes. After that, the corresponding solenoid valve shuts off the high air pressure of the air inlet, and the unloading hose opens under its own elasticity. All the gunpowder raw material in the first dispensing holes falls into the second dispensing holes below, and then into the gunpowder hole of the matching spray tube.
[0004] However, the aforementioned charging machine still has some problems to be solved. For example, during charging, all 127 first-stage discharge holes need to be filled with explosive raw materials before all 127 discharge hoses can be opened simultaneously to achieve synchronous and equal charging of the 127 holes of the spray tube, which results in low charging efficiency. In addition, since high-pressure air needs to be introduced into the counterbore, this poses new challenges to the equipment's sealing and safety. Moreover, the equipment must be equipped with corresponding high-pressure equipment to be used, which means that manufacturers not only need to purchase the charging machine but also need to purchase additional high-pressure equipment, which obviously increases the company's production costs.
[0005] Therefore, how to provide a charging device for loading fireworks and firecrackers with high charging efficiency, no need for high-pressure gas source, and low cost is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0006] In view of this, the present invention provides a loading device for cyclically receiving and quantitatively loading fireworks and firecrackers. This device not only has low production cost and high loading efficiency, but can also be used without a high-pressure gas source, which greatly meets the market demand for high efficiency and low cost in fireworks and firecrackers production.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A charging device for continuously dispensing and metering fireworks and firecrackers explosives includes:
[0009] An explosion-proof chamber, wherein the explosion-proof chamber has a barrel shell inlet and a barrel shell outlet;
[0010] A conveyor belt, which passes through the inlet and outlet of the barrel shell, is used to transport the barrel shell, which has multiple propellant holes.
[0011] A frame is fixed to the inner wall of the explosion-proof chamber and located above the conveyor belt; a feed hopper is fixed on the frame.
[0012] A geared motor is fixed to the top plate of the frame, and the drive shaft of the geared motor is arranged downward through the top plate;
[0013] A turntable is located above the conveyor belt. The top of the turntable is fixedly connected to the drive shaft of the geared motor via a connecting rod. Multiple medicine storage trays are embedded on the turntable, and each medicine storage tray has a medicine storage hole that matches the medicine hole.
[0014] The receiving mechanism is fixed to the bottom surface of the top plate and is used to receive the explosive raw materials from the feed hopper and to cyclically fill the storage holes of the multiple storage trays with explosive raw materials.
[0015] A loading mechanism, fixed on the frame, is used to cyclically fill the explosive raw materials in multiple storage trays filled with explosive raw materials into the propellant holes of the barrel shell on the conveyor belt;
[0016] The opening and closing mechanism consists of multiple mechanisms fixed to the bottom surface of the turntable. Each of the multiple opening and closing mechanisms is arranged in a one-to-one correspondence with the position of the multiple medicine storage trays, and is used to open and close the medicine storage holes, thereby realizing the medicine storage holes are aligned with the medicine holes for medicine loading.
[0017] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a charging device for quantitatively discharging and loading fireworks and firecrackers. During operation, a geared motor drives a turntable to rotate, causing the empty storage tray to rotate directly below the charging mechanism. A fixed amount of explosive material is fed into the charging mechanism through a feeding hopper. The charging mechanism fills the explosive material into multiple storage holes in the lower storage tray. At this time, an opening and closing mechanism located below the storage tray seals the lower opening of the storage holes to prevent leakage of the explosive material. Then, the geared motor drives the turntable to rotate again, rotating the storage tray filled with explosive material directly below the discharging mechanism. At this time, the opening and closing mechanism below the storage tray... The opening and closing mechanism opens the lower opening of the storage hole, and the next empty storage tray rotates to the bottom of the receiving mechanism. A fixed amount of explosive material is fed into the receiving mechanism through the feeding hopper to continue loading the storage tray below, thus loading the empty storage tray. At the same time, the unloading mechanism fills the explosive material in the storage tray below it into multiple holes of the barrel shell conveyed by the conveyor belt through the opened storage hole, thus unloading the full storage tray and loading the empty barrel shell. After that, the geared motor drives the turntable to rotate again, realizing the filling of the empty storage tray, unloading of the full storage tray, and filling of the empty barrel shell. This process is repeated to achieve continuous loading of multiple barrel shells.
[0018] Therefore, this charging device, by incorporating components such as a conveyor belt, a receiving mechanism, a loading mechanism, a turntable with multiple storage trays and opening / closing mechanisms, enables simultaneous receiving and loading of explosive materials. Furthermore, the turntable facilitates a reciprocating rotational process, significantly improving the charging efficiency of fireworks and firecrackers. In addition, all the above operations are conducted within a blast-resistant chamber, effectively preventing secondary explosions or injuries caused by accidents during fireworks and firecracker production.
[0019] Furthermore, the drug receiving mechanism includes:
[0020] A scraper motor is fixed to the bottom end surface of the top plate, and the drive shaft of the scraper motor is arranged downward.
[0021] The receiving cylinder is fixedly connected to the scraper motor via a support rod. The discharge port of the feed hopper is connected to the upper cylinder opening of the receiving cylinder, and the lower cylinder opening of the receiving cylinder is in contact with the top surface of the turntable. The medicine storage tray can be located inside the receiving cylinder.
[0022] A scraper assembly, fixed on the drive shaft of the scraper motor, is used to scrape the explosive raw material in the receiving tube into the storage hole on the storage tray.
[0023] The beneficial effects of adopting the above technical solution are as follows: the explosive raw material is fed into the receiving cylinder through the feeding hopper and falls onto the storage tray. Then, the scraper motor drives the scraper assembly to rotate and scrape the explosive raw material into the storage hole, realizing the loading of explosives into multiple storage holes.
[0024] Furthermore, the scraper assembly includes:
[0025] The mounting sleeve is fixedly mounted on the drive shaft of the scraper motor;
[0026] Mounting plate, the mounting plate being fixed to the mounting cylinder;
[0027] An arc-shaped scraper is detachably mounted on the mounting plate by screws.
[0028] The beneficial effects of adopting the above technical solution are as follows: because the scraper has an arc-shaped structure, when scraping the explosive material, it will not scrape the explosive material away from the outermost storage hole, thus ensuring that the explosive material inside the installation cylinder can be scraped evenly and completely to multiple storage holes; in addition, the severely worn arc-shaped scraper can be replaced at any time.
[0029] Furthermore, the receiving cartridge includes:
[0030] The cylinder is fixedly connected to the scraper motor via the support rod, the discharge port of the feed hopper is connected to the upper cylinder opening of the cylinder, and the medicine storage tray can be located inside the cylinder;
[0031] A deflector friction ring is detachably installed on the lower opening of the cylinder body, and the bottom end of the deflector friction ring contacts the top surface of the turntable.
[0032] The beneficial effects of adopting the above technical solution are as follows: the detonator friction ring can not only seal the gap between the cylinder and the turntable, preventing the explosive material inside the cylinder from overflowing, but also keep the explosive material inside the cylinder at all times, ensuring that the quantitative explosive falls into the storage hole, realizing the quantitative loading of the subsequent explosive holes. Moreover, the detonator friction ring is a replaceable part. When the detonator friction ring is severely worn, only the detonator friction ring needs to be replaced, without replacing the cylinder, which greatly reduces the maintenance cost of parts.
[0033] Furthermore, the unloading mechanism includes:
[0034] The pressing cylinder is fixed on the frame;
[0035] A pressure plate, the top of which is fixed to the telescopic end of the pressing cylinder, and a plurality of pressing rods are fixed on the bottom surface of the pressure plate. The pressing rods can extend into the storage hole to push out the explosive material inside.
[0036] The beneficial effects of adopting the above technical solution are as follows: when the storage tray fully loaded with explosive raw materials rotates to the bottom of the pressure plate, the opening and closing mechanism is activated, opening the lower opening of the storage hole on the storage tray. The pressing cylinder is activated, driving the pressure plate to move down. The pressing rod on the pressure plate extends into the storage hole, pushing the explosive raw materials located in the storage hole out of the storage hole, so that the explosive raw materials fall into the gun barrel shell below, realizing the loading of the gun barrel shell.
[0037] Furthermore, each of the opening and closing mechanisms includes:
[0038] An opening and closing material discharge plate is fixed on the bottom surface of the turntable and is arranged in a position corresponding to the medicine storage plate, and is used to open and close the medicine storage hole.
[0039] The material distribution plate is fixed to the bottom surface of the opening and closing material dropping plate and is used to receive the explosive raw materials falling from the explosive storage hole. The material distribution plate is provided with a plurality of explosive distribution holes that match the explosive hole.
[0040] A drive cylinder is fixed on the inner wall of the explosion-proof chamber and is used to drive the opening and closing feed plate to open and close the drug storage hole.
[0041] The beneficial effects of adopting the above technical solution are as follows: During the initial material receiving, the opening and closing feed plate closes the lower opening of the storage hole, ensuring that the storage hole can be filled with explosives without overflowing when the arc-shaped scraper scrapes the explosives. When the storage plate, which is fully loaded with explosive raw materials, rotates to the bottom of the pressure plate, the driving cylinder drives the opening and closing feed plate to open the lower opening of the storage hole. The pressing cylinder moves the pressure plate downward, and the pressing rod on the pressure plate extends into the storage hole, pushing the explosive raw materials in the storage hole out of the storage hole, so that the explosive raw materials fall into the distribution hole below, and then fall into the explosive hole on the barrel shell below through the distribution hole, thus realizing the loading of explosives into the barrel shell.
[0042] Furthermore, the opening and closing feed tray includes:
[0043] A frame is fixed to the bottom surface of the turntable and is arranged corresponding to the position of the medicine storage tray; the material distribution tray is fixed to the bottom surface of the frame.
[0044] A flip-type baffle, wherein multiple flip-type baffles are arranged side by side, the flip-type baffles cover the lower opening of the corresponding medicine storage hole, and the mounting shaft on each flip-type baffle is rotatably mounted on the first side beam and the second side beam of the frame, and a first rocker arm and a second rocker arm are fixed at both ends of each mounting shaft.
[0045] The first link is placed in the first cavity of the first side beam, and the first link is hinged to the plurality of first rocker arms.
[0046] A reset spring 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] The second link is placed in the second cavity of the second side beam, and the second link is hinged to multiple second rocker arms.
[0048] An intermediate connecting rod is placed inside the second cavity, and one end of the intermediate connecting rod is hinged to the second connecting rod;
[0049] A drive rod, one end of which is hinged to the other end of the intermediate connecting rod, and the other end of which extends outward from the second side beam. The telescopic end of the drive cylinder can abut against the other end of the drive rod to drive the flip-type baffle to flip downward, thereby opening the explosive storage hole and allowing the explosive material in the explosive storage hole to fall into the explosive hole through the explosive distribution hole.
[0050] The beneficial effects of adopting the above technical solution are as follows: When receiving material initially, the opening and closing of the material discharge plate seals the lower opening of the storage hole. Specifically, under the action of the return spring, the flip-type baffle is in a horizontal position and fits against the lower opening of the storage hole to ensure that the storage hole can be filled with medicine without leakage when the arc-shaped scraper scrapes the medicine. When the storage tray filled with explosive material rotates to the bottom of the pressure plate, the drive cylinder pushes the drive rod, which in turn moves the second connecting rod via the intermediate connecting rod. This, in turn, causes the flip-type baffle to flip downwards via the second rocker arm, opening the lower opening of the storage hole. The pressing cylinder then moves the pressure plate downwards, and the pressing rod on the pressure plate extends into the storage hole, pushing the explosive material out of the storage hole and allowing it to fall into the propellant hole on the lower barrel shell, thus loading the barrel shell. At this time, the first rocker arm, driven by the mounting shaft, compresses or stretches the return spring of the first connecting rod. After the propellant hole is loaded, the drive cylinder stops pushing the drive rod, and under the action of the return spring, the flip-type baffle returns to a horizontal position and closes to seal the lower opening of the storage hole for subsequent loading.
[0051] Furthermore, the dispensing hole is a conical hole with a larger upper hole and a smaller lower hole.
[0052] The beneficial effects of adopting the above technical solution are: it makes it easier for the dispensing hole to receive the explosive raw materials in the storage hole, and achieves equal loading of multiple holes.
[0053] Furthermore, it also includes: a barrel shell lifting mechanism, which comprises:
[0054] Lifting cylinders, there are two lifting cylinders, which are respectively fixed on the frame of the conveyor belt;
[0055] A lifting plate, with both ends fixed to the telescopic ends of the two lifting cylinders, is located between the upper and lower belts of the conveyor belt and is used to lift the barrel shell located on the upper belt so that the barrel shell is connected to the material distribution plate.
[0056] The beneficial effects of adopting the above technical solution are as follows: After the barrel shell is transported to the bottom of the dispensing tray by the conveyor belt, the lifting cylinder drives the lifting plate to move up, which in turn drives the barrel shell to move up, so that the barrel shell is connected with the dispensing tray, thereby reducing the distance between the propellant hole and the dispensing hole, which facilitates the dropping of explosives and avoids the problem that the explosive material in the dispensing hole cannot be completely dropped into the propellant hole due to the large distance between the propellant hole and the dispensing hole and the susceptibility of external wind.
[0057] Furthermore, the conveyor belt includes:
[0058] The first conveyor belt is used to transport the barrel shell to the area below the distribution plate. The first conveyor belt passes through the inlet of the barrel shell. The lifting cylinder is fixed on the frame of the first conveyor belt. The lifting plate is located between the upper and lower belts of the first conveyor belt.
[0059] A second conveyor belt is installed at the outlet of the barrel shell, with the beginning of the second conveyor belt connected to the end of the first conveyor belt.
[0060] A push cylinder, which is fixed to the end of the frame of the first conveyor belt or fixed to the inner wall of the blast-resistant chamber, is used to push the barrel shell filled with explosives on the first conveyor belt onto the second conveyor belt.
[0061] The beneficial effect of adopting the above technical solution is that the gun barrel shell filled with explosives on the first conveyor belt can be pushed to the second conveyor belt and moved out of the explosion-proof room to the next process through the push cylinder.
[0062] Furthermore, it also includes two opposing barrel housing positioning mechanisms, each of which includes:
[0063] A positioning cylinder, which is fixed to the inner wall of the explosion-proof chamber;
[0064] A positioning clamp, which is fixed to the drive end of the positioning cylinder, is used to clamp and position the barrel shell on the first conveyor belt.
[0065] The beneficial effects of adopting the above technical solution are as follows: after the barrel shell is transported to the bottom of the dispensing plate by the conveyor belt, the two positioning cylinders are activated to drive the two positioning clamps to clamp and position the barrel shell, so that the propellant hole on the barrel shell can correspond to the position of the dispensing hole, and the explosive material in the dispensing hole can be accurately loaded into the propellant hole.

[0141] The working principle of this utility model is as follows:
[0142] During operation, the geared motor drives the turntable to rotate, positioning the empty explosive storage tray directly below the receiving mechanism. A measured amount of explosive material is fed into the receiving mechanism via the feed hopper. The receiving mechanism then fills the explosive material into multiple storage holes in the lower explosive storage tray. At this point, the opening and closing mechanism located below the storage tray seals the lower opening of the storage hole to prevent leakage of explosive material. Then, the geared motor drives the turntable to rotate again, positioning the explosive-filled storage tray directly below the unloading mechanism. The opening and closing mechanism below this storage tray then opens the lower opening of the storage hole, and the next empty explosive storage tray rotates... Directly below the receiving mechanism, a fixed amount of explosive material is fed into the receiving mechanism again through the feeding hopper to continue loading the storage pan below it, thus loading the empty storage pan. At the same time, the unloading mechanism fills the explosive material in the storage pan below it into multiple propellant holes in the barrel shell conveyed by the conveyor belt through the opened storage holes, thus unloading the full storage pan and loading the empty barrel shell. Afterward, the geared motor drives the turntable to rotate again, realizing the filling of the empty storage pan, unloading of the full storage pan, and filling of the empty barrel shell. This process is repeated to achieve continuous loading of multiple barrel shells.

[0145] (2) The device does not require the introduction of high-pressure gas, has low requirements for the sealing performance of the device, and can be used without purchasing high-pressure equipment. Therefore, the device has a low cost and meets the low-cost production needs of enterprises.
[0146] (3) An opening and closing mechanism is provided to realize the automatic opening and closing of the lower opening of the drug storage hole, thereby realizing the loading and unloading of drugs.
[0147] (4) An explosion-proof room was set up to improve the safety of fireworks and firecrackers production.
