Description

Technical Field

[0001] This utility model relates to the field of zinc alloy smelting technology, specifically to a quantitative feeding device for zinc alloy smelting equipment. Background Technology

[0002] Zinc alloys are alloys composed of zinc as the base and alloying elements such as aluminum, copper, magnesium, cadmium, lead, and titanium. Their performance and quality vary significantly depending on the element ratio and smelting process. During the smelting process, the alloy material needs to be melted into a liquid state using melting equipment and then injected into a specific mold cavity for subsequent processing. The precise quantitative input of metal raw materials plays an important role in product quality and production efficiency. In traditional processes, metal ingots of fixed mass are often used as raw materials, and quantitative input is achieved by controlling the number of metal ingots put into the melting furnace. This method is relatively simple to operate, but it has its drawbacks.

[0003] During the handling and loading / unloading of metal ingots, they are prone to collisions with surrounding equipment and other metal ingots, causing metal fragments to fall off. This not only changes the quality of the metal ingots, but also makes it less accurate to judge the quality of the metal to be smelted based on the number of metal ingots, resulting in deviations in the amount of material fed in and an imbalance in the proportion of zinc alloy components, which in turn affects the quality of the final product and causes an increase in the product defect rate.

[0004] To address the aforementioned problems, the inventors have proposed a quantitative feeding device for zinc alloy smelting equipment. Utility Model Content

[0005] To address the problem that existing methods for quantitatively controlling the quality of metal raw materials by judging the number of metal ingots can easily lead to deviations in the amount of material fed, the purpose of this utility model is to provide a quantitative feeding device for zinc alloy smelting equipment.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: a quantitative feeding device for zinc alloy smelting equipment, including a casting furnace, a feeding rack on one side of the casting furnace, the feeding rack being installed at the feeding port of the casting furnace by fastening bolts, a placement platform on the upper part of the feeding rack, a weighing scale installed at the bottom of the placement platform, gears fixedly installed on the middle of both sides of the weighing scale, two gears rotatably installed on the middle of the feeding rack on both sides, toothed plates on the lower part of the two gears, both toothed plates meshing with the gears, a push plate fixedly installed on one side of the two toothed plates, a drive assembly on one side of the push plate, a scraper on one side of the placement platform, a screw rotatably installed on one side of the placement platform, a moving block threaded on the outer surface of the screw, a scraper rotatably installed on the middle of one side of the moving block, a first micro motor fixedly installed on one side of the placement platform, and one end of the screw fixedly installed on the drive end of the first micro motor.

[0007] Preferably, the other side of the scraper is provided with a housing, a second micro motor is fixedly installed on one side of the bottom end of the housing, a worm gear is rotatably installed on one side of the lower part of the housing, one end of the worm gear is fixedly installed on the drive end of the second micro motor, a worm wheel is rotatably installed on the upper part of the housing, one end of the scraper is fixedly installed on the middle of one side of the worm wheel, and two symmetrically distributed slots are opened on the upper part of the placement platform, and the housing and the moving block are slidably locked inside the slots.

[0008] Preferably, the driving assembly includes an electric push rod, which is fixedly installed on one side of the top of the feeding rack. A push plate is fixedly installed on the driving end of the electric push rod at the middle of one side. Sliders are fixedly installed at the bottom ends of the two toothed plates. Two symmetrically distributed grooves are opened at the top of the feeding rack. The two sliders are slidably engaged inside the grooves. Two symmetrically distributed baffles are detachably installed at the top of the placement platform. Two symmetrically distributed grooves are opened at the top of the placement platform. The lower sides of the scraper are slidably engaged inside the grooves.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. This application uses a weighing scale to measure the weight of zinc alloy raw materials on the platform in real time, and uses an electric push rod, gears and toothed plates to put the measured raw materials into the melting and casting furnace. This allows for precise control of the amount of raw materials entering the melting and casting furnace each time, effectively avoiding deviations in the amount of material fed due to metal ingot collisions, which could lead to unstable product quality.

[0011] 2. This application automatically cleans the placement platform by setting a scraper after each metal ingot feeding. The scraper is driven by a first micro motor and a screw, and the scraper angle is adjusted by a second micro motor in conjunction with a worm gear and worm wheel.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Figure 1-5 As shown, this utility model provides a quantitative feeding device for zinc alloy smelting equipment, including a melting furnace 1. The melting furnace 1 is used for smelting zinc alloy. A feeding rack 2 is provided on one side of the melting furnace 1. A placement platform 26 is provided on the upper part of the feeding rack 2. The placement platform 26 is used to place the metal ingot raw material to be smelted. A weighing scale 25 is installed at the bottom of the placement platform 26. The weighing scale 25 can accurately measure the weight of the zinc alloy raw material on the placement platform 26 in real time, thereby providing data support for quantitative feeding. Gears 24 are fixedly installed in the middle of both sides of the weighing scale 25. Both sides of the two gears 24 are rotatably installed in the middle of the feeding rack 2. Tooth plates 23 are provided at the lower part of the two gears 24. Both tooth plates 23 are meshed with the gears 24. When the tooth plates 23 move, they will drive the meshing gears 24 to rotate. A push plate 22 is fixedly installed on one side of the two tooth plates 23. A drive assembly is provided on one side of the push plate 22.

[0021] A scraper 3 is provided on one side of the placement platform 26. The scraper 3 is used to clean the residual zinc alloy raw materials on the placement platform 26 to ensure the accuracy of the feeding amount. A screw 33 is rotatably installed on one side of the placement platform 26. A moving block 34 is threaded on the outer surface of the screw 33. The scraper 3 is rotatably installed on one side of the moving block 34 in the middle. A first micro motor 32 is fixedly installed on one side of the placement platform 26. One end of the screw 33 is fixedly installed on the drive end of the first micro motor 32. When the first micro motor 32 is started, it will drive the screw 33 to rotate. Since the moving block 34 is threadedly engaged with the screw 33, the rotation of the screw 33 will cause the moving block 34 to move along the axial direction of the screw 33, thereby driving the scraper 3 to move.

[0022] On the other side of the scraper 3, there is a housing 35. A second micro motor 36 is fixedly installed on one side of the bottom of the housing 35. A worm gear 37 is rotatably installed on the lower side of the housing 35. One end of the worm gear 37 is fixedly installed on the drive end of the second micro motor 36. A worm wheel 38 is rotatably installed on the upper part of the housing 35. One end of the scraper 3 is fixedly installed on the middle of one side of the worm wheel 38. Through the cooperation of the second micro motor 36, the worm gear 37, and the worm wheel 38, the angle of the scraper 3 can be adjusted. When the scraper 3 is working, it can be made to be perpendicular to the placement platform 26, which facilitates the removal of the garbage stuck on the placement platform 26. When the scraper 3 is not working, its side is at the same level as the upper surface of the placement platform 26, thereby ensuring that the metal ingot is placed on the upper part of the placement platform 26 without interference.

[0023] The drive assembly includes an electric push rod 21, which is fixedly installed on one side of the top of the feeding rack 2. The middle of one side of the push plate 22 is fixedly installed on the drive end of the electric push rod 21. The electric push rod 21 is the drive source and can provide a stable linear thrust. When the electric push rod 21 is started, its drive end will push the push plate 22 to move, thereby driving the toothed plate 23 to move.

[0024] To ensure the stability of the movement of the toothed plate 23, a slider 231 is fixedly installed at the bottom of each of the two toothed plates 23. Two symmetrically distributed slide grooves are opened on the upper part of the feeding rack 2. The two sliders 231 are slidably locked inside the slide grooves. The cooperation between the sliders 231 and the slide grooves can effectively prevent the toothed plate 23 from shifting during the movement.

[0025] The top of the placement platform 26 is detachably equipped with two symmetrically distributed baffles 27. The baffles 27 can prevent zinc alloy raw materials from falling from the edge of the placement platform 26, and the detachable design facilitates cleaning and maintenance of the placement platform 26.

[0026] The upper part of the placement platform 26 has two symmetrically distributed grooves 31. The lower sides of the scraper 3 are slidably locked inside the grooves 31. The grooves 31 provide guidance for the movement of the scraper 3, ensuring that the scraper 3 can accurately clean the placement platform 26.

[0027] The upper part of the placement platform 26 has two symmetrically distributed slots. The housing 35 and the moving block 34 are slidably locked inside the slots. The slots can limit the housing 35 and the moving block 34, preventing the housing 35 from rotating with the rotation of the screw 33, and making the sliding of the moving block 34 more stable.

[0028] The feeding rack 2 is installed at the feeding port of the melting and casting furnace equipment 1 by fastening bolts. The bolt installation method not only ensures the stability of the connection between the feeding rack 2 and the melting and casting furnace equipment 1, but also facilitates subsequent disassembly and maintenance.

[0029] Working principle: When the casting furnace equipment 1 is working, after the operator sets the weight of the metal ingot to be put into the weighing scale 25, the operator will transfer the metal ingot to be put into the casting furnace equipment 1 to the upper part of the placement platform 26 by means of forklift or other means. At this time, the weighing scale 25 at the lower part of the placement platform 26 will work to weigh and record the weight of the metal ingot on the placement platform 26. After the recording is completed, the push plate 22 will be moved by the electric push rod 21, which will drive the two toothed plates 23 to move to one side synchronously, thereby driving the gear 24 meshing with it to rotate, which will cause the placement platform 26 to deflect at an angle, causing the metal ingot placed on the placement platform 26 to slide to one side and enter the interior of the casting furnace equipment 1. The process of weighing and putting the metal ingot into the casting furnace equipment 1 is repeated in this way. When the weight reaches the standard, the weighing scale 25 will sound an alarm to remind the operator that the required weight has been reached, thereby stopping the feeding operation.

[0030] Meanwhile, whenever the placement platform 26 tilts so that the metal ingot slides completely into the melting furnace equipment 1, if there are metal ingot debris generated by the impact remaining on the placement platform, the second micro motor 36 can be started to drive its worm gear 37 to rotate, which in turn drives the meshing worm wheel 38 to rotate, thereby driving the scraper 3 to rotate and adjust its angle so that it is perpendicular to the placement platform 26. At this time, the lower part of the scraper 3 is in contact with the upper surface of the placement platform 26. The first micro motor 32 is started to drive the screw 33 to rotate, which drives the moving block 34 with the thread installed on it to move, thereby driving the scraper 3 to move on the upper surface of the placement platform 26 and scraping out the remaining debris.

[0031] After scraping is completed, the scraper 3 can be reset to one side of the placement platform 26 by the reverse rotation of the first micro motor 32. Under the reverse rotation of the second micro motor 36, the scraper 3 is reset to be on the same horizontal plane as the placement platform 26. At this time, under the reverse drive of the electric push rod 21, the placement platform 26 is rotated and reset to a horizontal state so that it can continue to be used for feeding.

[0032] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
