Description

Technical Field

[0001] The invention relates to the technical field of fireworks and firecrackers production machinery and equipment, and more particularly to a charge device for cyclically receiving and quantitatively charging fireworks and firecrackers. Background Art

[0002] At present, the existing publication number is CN111811334A, and the name is a fireworks charging machine. 127 rubber unloading hoses are built into the charging device. By ventilating and squeezing the rubber unloading hoses in the countersunk holes to close the rubber unloading hoses, the 127 rubber unloading hoses can be opened and closed at the same time, thereby realizing synchronous and equal charging of the 127 medicine holes of the spray tube.

[0003] In the specific charging process, the feeding device first adds the cold fireworks raw materials into the powder barrel, and then drives the scraper through the hydraulic stirring motor to evenly scrape the raw materials to the 127 first powder holes. After that, the corresponding solenoid valve turns off the high air pressure of the air inlet joint, and the unloading hose opens under the action of its own elasticity. The gunpowder raw materials in the first powder holes all fall into the second powder holes below, and then fall into the powder holes of the matching spray barrel.

[0004] However, the above-mentioned charging machine still has some problems to be solved. For example, when charging, all 127 first charge holes need to be filled with explosive raw materials before 127 unloading hoses can be opened at the same time to realize synchronous and equal charging of 127 charge holes of the spray tube, and its charging efficiency is not high. In addition, since high-pressure gas needs to be introduced into the countersunk hole, this poses new challenges to the sealing and safety of the equipment. Moreover, when the equipment is used, it must be equipped with corresponding high-pressure equipment. As a result, the production enterprise not only needs to purchase the charging equipment, but also needs to purchase high-pressure equipment additionally, which obviously also increases the production cost of the enterprise.

[0005] Therefore, how to provide a charging device for fireworks and firecrackers with high charging efficiency, no need for a high-pressure gas source, and low cost, which can cyclically receive and quantitatively charge the charging materials, is an urgent problem to be solved by technicians in this field. Summary of the invention

[0006] In view of this, the present invention provides a charging device for fireworks and firecrackers that can be cyclically charged and quantitatively charged. The device has not only low production cost but also high charging efficiency and can be used without a high-pressure gas source, thus greatly meeting the market demand for high-efficiency and low-cost production of fireworks and firecrackers.

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

[0008] The charging device for charging fireworks and firecrackers by circulating and quantitatively charging the charges comprises:

[0009] A conveyor belt, used for conveying a barrel shell, wherein the barrel shell has a plurality of powder holes;

[0010] A frame, the frame is arranged across the conveyor belt, and a feed hopper is fixed on the frame;

[0011] A reduction motor, wherein the reduction motor is fixed on the top plate of the frame, and a driving shaft of the reduction motor passes through the top plate and is arranged downward;

[0012] A turntable, the turntable is located above the conveyor belt, the top of the turntable is fixedly connected to the driving shaft of the reduction motor, a plurality of medicine storage trays are embedded on the turntable, and the medicine storage trays are provided with medicine storage holes matching the medicine holes;

[0013] A charge receiving mechanism, the charge receiving mechanism is fixed on the bottom end surface of the top plate, and is used to receive the explosive raw materials from the feed hopper and cyclically fill the explosive raw materials into the charge storage holes of the plurality of charge storage trays;

[0014] A loading mechanism, which is fixed to the frame and is used to cyclically load the explosive raw materials in the plurality of medicine storage trays filled with explosive raw materials into the medicine holes of the barrel shell on the conveyor belt;

[0015] The opening and closing mechanism is a plurality of opening and closing mechanisms fixed on the bottom surface of the turntable, and the plurality of opening and closing mechanisms are arranged one-to-one corresponding to the positions of the plurality of medicine storage disks, and are used to open and close the medicine storage holes, thereby realizing the medicine storage holes to charge the medicine holes.

[0016] Through the above technical scheme, it can be known that compared with the prior art, the present invention discloses a charging device for fireworks and firecrackers that cyclically receives and quantitatively loads fireworks and firecrackers. When working, the reduction motor drives the turntable to rotate, so that the empty medicine storage tray is rotated to the bottom of the medicine receiving mechanism, and a quantitative amount of explosive raw materials is put into the medicine receiving mechanism through the feed hopper. The medicine receiving mechanism fills the explosive raw materials into multiple medicine storage holes in the medicine storage tray below. At this time, the opening and closing mechanism below the medicine storage tray closes the lower openings of the medicine storage holes to prevent the explosive raw materials in the medicine storage holes from leaking. Then, the reduction motor drives the turntable to rotate again, and the medicine storage tray filled with explosive raw materials is rotated to the bottom of the loading mechanism. At this time, the opening and closing mechanism below the medicine storage tray closes the lower openings of the medicine storage holes. The closing mechanism opens the lower hole of the medicine storage hole, and the next empty medicine storage tray rotates to the bottom of the medicine receiving mechanism, and a certain amount of explosive raw materials are put into the medicine receiving mechanism through the feed hopper again to continue to charge the medicine storage tray below it, thereby realizing the charging of the empty medicine storage tray. At the same time, the loading mechanism fills the explosive raw materials in the medicine storage tray below it through the opened medicine storage holes into the multiple medicine holes of the barrel shell conveyed by the conveyor belt, thereby realizing the unloading of the fully loaded medicine storage tray and the charging of the empty barrel shell. After that, the reduction motor drives the turntable to rotate again, thereby realizing the filling of the empty medicine storage tray, the unloading of the fully loaded medicine storage tray, and the filling of the empty barrel shell. This process is repeated to realize the continuous charging of multiple barrel shells.

[0017] Therefore, the charging device can realize the simultaneous charging and charging of explosive raw materials by arranging components such as a conveyor belt, a charge receiving mechanism, a loading mechanism, a turntable and multiple charge storage trays and multiple opening and closing mechanisms thereon, and the process is realized by the rotating and reciprocating operation of the turntable, which greatly improves the charging efficiency of fireworks and firecrackers.

[0018] Furthermore, the medicine receiving mechanism includes:

[0019] A scraper motor, wherein the scraper motor is fixed on the bottom end surface of the top plate, and a driving shaft of the scraper motor is arranged downward;

[0020] A medicine receiving barrel, wherein the medicine receiving barrel is fixedly connected to the scraper motor through a support rod, the discharge port of the feed hopper is connected to the upper barrel port of the medicine receiving barrel, the lower barrel port of the medicine receiving barrel is in contact with the top surface of the rotating disk, and the medicine storage disk can be located in the medicine receiving barrel;

[0021] A scraper assembly is fixed on the driving shaft of the scraper motor and is used to scrape the explosive raw materials in the medicine receiving barrel into the medicine storage holes on the medicine storage tray.

[0022] The beneficial effect of adopting the above technical solution is that the explosive raw materials are put into the medicine receiving barrel through the feed hopper and fall on the medicine storage plate. Then the scraper motor drives the scraper assembly to rotate and scrape the explosive raw materials into the medicine storage holes, thereby realizing the charging of multiple medicine storage holes.

[0023] Furthermore, the scraper assembly comprises:

[0024] A mounting cylinder, wherein the mounting cylinder is sleeved and fixed on the driving shaft of the scraper motor;

[0025] A mounting plate, the mounting plate being fixed on the mounting tube;

[0026] The arc-shaped scraper is detachably mounted on the mounting plate by screws.

[0027] The beneficial effect of adopting the above technical solution is: because the scraper has an arc-shaped structure, when scraping the explosive raw materials, the explosive raw materials will not be scraped away from the outermost storage holes, thereby ensuring that the explosive raw materials inside the installation tube can be evenly and completely scraped to multiple storage holes; and the arc-shaped scraper that is severely worn can be replaced at any time.

[0028] Furthermore, the medicine receiving cartridge includes:

[0029] The barrel is fixedly connected to the scraper motor through the support rod, the discharge port of the feed hopper is connected to the upper barrel port of the barrel, and the medicine storage tray can be located in the barrel;

[0030] The medicine-blocking friction ring is detachably mounted on the lower barrel opening of the barrel, and the bottom end of the medicine-blocking friction ring contacts the top end surface of the rotating disk.

[0031] The beneficial effects of adopting the above technical scheme are: the medicine-blocking friction ring can not only close the gap between the cylinder and the turntable, and play a role in preventing the explosive raw materials inside the cylinder from overflowing, but also always limit the explosive raw materials inside the cylinder, ensuring that all the quantitative explosives fall into the medicine storage holes, and realizing the subsequent quantitative loading of the medicine holes, and the medicine-blocking friction ring is a replaceable part. When the medicine-blocking friction ring is severely worn, it only needs to be replaced without replacing the cylinder, thereby greatly reducing the maintenance cost of parts.

[0032] Furthermore, the drop-off mechanism comprises:

[0033] A pressing cylinder, the pressing cylinder is fixed on the frame;

[0034] A pressing plate, the top of which is fixed on the telescopic end of the pressing cylinder, and a plurality of pressing rods are fixed on the bottom end surface of the pressing plate, and the pressing rods can be extended into the drug storage hole to push out the explosive raw materials inside it.

[0035] The beneficial effect of adopting the above technical solution is: when the medicine storage tray fully loaded with explosive raw materials is rotated to the bottom of the pressure plate, the opening and closing mechanism is activated to open the lower hole of the medicine storage hole on the medicine storage tray, the pressing cylinder is activated to drive the pressure plate to move downward, and the pressing rod on the pressure plate extends into the medicine storage hole to push the explosive raw materials in the medicine storage hole out of the medicine storage hole, so that the explosive raw materials fall into the medicine hole on the barrel shell below, thereby realizing the loading of the barrel shell.

[0036] Furthermore, each of the opening and closing mechanisms comprises:

[0037] An opening and closing material drop tray, which is fixed to the bottom end surface of the rotating disk and arranged corresponding to the position of the medicine storage tray, and is used to open and close the medicine storage hole;

[0038] A material distribution plate, the material distribution plate is fixed on the bottom end surface of the opening and closing material drop plate, and is used to receive the explosive raw materials dropped from the drug storage holes. The material distribution plate is provided with a plurality of drug distribution holes matching the drug holes;

[0039] A driving cylinder is fixed on the frame and is used to drive the opening and closing of the blanking tray to realize the opening and closing of the medicine storage hole.

[0040] The beneficial effects of adopting the above technical scheme are as follows: when initially receiving the materials, the opening and closing material blanking plate closes the lower hole of the medicine storage hole to ensure that the medicine storage hole can be loaded with medicine when the arc scraper scrapes the medicine; when the medicine storage plate fully loaded with explosive raw materials rotates to the bottom of the pressure plate, the driving cylinder drives the opening and closing material blanking plate to open the lower hole of the medicine storage hole, and the pressing cylinder drives the pressure plate to move downward, and the pressing rod on the pressure plate extends into the medicine storage hole, pushing the explosive raw materials in the medicine storage hole out of the medicine storage hole, so that the explosive raw materials fall into the medicine distribution hole below, and then fall into the medicine hole on the barrel shell below through the medicine distribution hole, so as to realize the loading of the barrel shell.

[0041] Further, the opening and closing of the blanking tray comprises:

[0042] A frame, the frame is fixed on the bottom end surface of the turntable and arranged corresponding to the position of the medicine storage tray, and the material distribution tray is fixed on the bottom end surface of the frame;

[0043] A flip-type baffle, wherein the flip-type baffle is arranged in a plurality in parallel, the flip-type baffle shields the lower opening of the corresponding medicine storage hole, 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 the first rocker arm and the second rocker arm are fixed at both ends of each mounting shaft;

[0044] A first connecting rod, the first connecting rod is disposed in a first cavity of the first side beam, and the first connecting rod is hinged to the first rocker arms;

[0045] A return spring, wherein the return spring is placed in the first cavity, one end of the return spring is fixedly connected to a cavity wall of one side of the first cavity, and the other end of the return spring is fixedly connected to one end of the first connecting rod;

[0046] a second connecting rod, the second connecting rod being disposed in a second cavity of the second side beam, the second connecting rod being hinged to each of the plurality of second rocker arms;

[0047] An intermediate connecting rod, the intermediate connecting rod is disposed in the second cavity, and one end of the intermediate connecting rod is hinged to the second connecting rod;

[0048] A driving rod, one end of which is hinged to the other end of the intermediate connecting rod, and the other end of which extends out of the second side beam arrangement. 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 to realize the opening of the drug storage hole, thereby allowing the explosive raw materials in the drug storage hole to fall into the drug hole through the drug distribution hole.

[0049] The beneficial effect of adopting the above technical solution is: when initially receiving the material, the opening and closing of the blanking plate closes the lower hole of the medicine storage hole. Specifically, under the action of the reset spring, the flip baffle is in a horizontal position and fits the lower hole of the closed medicine storage hole, ensuring that the medicine storage hole can be loaded with medicine without leakage when the arc scraper scrapes the medicine. When the medicine storage tray fully loaded with explosive raw materials rotates to the bottom of the pressure plate, the driving cylinder is actuated to push the driving rod, and the driving rod drives the second connecting rod to move through the middle connecting rod, and then drives the flip-type baffle to flip downward through the second rocker arm, so that the lower hole of the medicine storage hole is opened, and the pressing cylinder is actuated to drive the pressing plate to move downward, and the pressing rod on the pressing plate extends into the medicine storage hole, and the explosive raw materials in the medicine storage hole are pushed out of the medicine storage hole, so that the explosive raw materials fall into the medicine hole on the barrel shell below, so as to load the medicine in the barrel shell. At this time, the first rocker arm, driven by the mounting shaft, compresses or stretches the reset spring of the first connecting rod. After the medicine hole is loaded, the driving cylinder no longer pushes the driving rod. Under the action of the reset spring, the flip-type baffle is in a horizontal position again, and fits the lower hole of the closed medicine storage hole for the next medicine storage hole to be used for loading.

[0050] Furthermore, the medicine dispensing hole is a tapered hole with a larger upper hole and a smaller lower hole.

[0051] The beneficial effect of adopting the above technical solution is that the charge-dividing holes can more easily receive the explosive raw materials in the charge-storage holes, thereby achieving equal charging of multiple charge holes.

[0052] Furthermore, it also includes two relatively arranged barrel casing positioning mechanisms, each of which includes:

[0053] A positioning cylinder, wherein the positioning cylinder is fixed on the frame;

[0054] A positioning clamping plate is fixed on the driving end of the positioning cylinder and is used to clamp and position the barrel shell.

[0055] The beneficial effect of adopting the above technical solution is: after the barrel shell is transported to the bottom of the medicine dispensing plate by the conveyor belt, the two positioning cylinders are actuated to drive the two positioning clamps to clamp and position the barrel shell, so that the medicine holes on the barrel shell can correspond to the positions of the medicine dispensing holes, thereby facilitating the accurate placement of the explosive raw materials in the medicine dispensing holes into the medicine holes.

[0056] Furthermore, it also includes: a barrel shell lifting mechanism, which includes:

[0057] Lifting cylinders, two of which are fixed on both sides of the conveyor belt respectively;

[0058] A lifting plate, both ends of which are fixed on the telescopic ends of the two lifting cylinders, and the lifting plate is located between the upper belt and the lower belt of the conveyor belt, and is used to lift the barrel shell located on the upper belt so that the barrel shell is docked with the material distribution plate.

[0059] The beneficial effect of adopting the above technical scheme is: after the barrel shell is transported to the bottom of the medicine distribution plate by the conveyor belt, the lifting cylinder drives the lifting plate to move up, and then drives the barrel shell to move up, so that the barrel shell and the material distribution plate are docked, thereby shortening the distance between the medicine hole and the medicine distribution hole, making it easier to drop the medicine, and avoiding the problem that the explosive raw materials in the medicine distribution holes cannot be completely dropped into the medicine holes due to the large distance between the medicine holes and the medicine distribution holes being easily affected by the external wind.

[0124] During operation, the reduction motor drives the turntable to rotate, so that the empty medicine storage tray rotates to the bottom of the medicine receiving mechanism, and a certain amount of explosive raw materials are put into the medicine receiving mechanism through the feeding hopper. The medicine receiving mechanism fills the explosive raw materials into the multiple medicine storage holes in the medicine storage tray below.

Then, the reduction motor drives the turntable to rotate again, and the medicine storage tray filled with explosive raw materials rotates to the bottom of the loading mechanism. At this time, the opening and closing mechanism below the medicine storage tray opens the lower openings of the medicine storage holes, and the next empty medicine storage tray rotates. When it reaches the bottom of the medicine receiving mechanism, a certain amount of explosive raw materials is put into the medicine receiving mechanism through the feed hopper again to continue charging the medicine storage tray below it, thereby realizing the charging of the empty medicine storage tray.
