Description

Technical Field

[0001] This invention relates to the field of carbon electrode production equipment technology, specifically to a carbon electrode forming machine. Background Technology

[0002] The production process of carbon electrodes includes multiple steps such as ingredient preparation, mixing, vibration molding, and firing. The vibration molding step typically requires a molding machine. Existing molding machines require manual oiling of the mold box before vibration, which presents the following problems: 1. Uneven manual oiling results in a large contact area between the carbon electrode and the mold box surface after pressing, leading to excessive friction and slow demolding, resulting in poor demolding performance; 2. It easily wastes oil; 3. It creates a harsh working environment. Furthermore, the carbon electrodes need to be sprayed with water during demolding. Current methods involve manual external water spraying, which is superficial and ineffective in cleaning and cooling the carbon electrode surface.

[0003] Chinese patent application number CN201310642938.9 discloses a vibration molding machine for carbon products, belonging to carbon production equipment. This vibration molding machine consists of a vibration platform, amplitude box, amplitude adjustment box, power motor, universal drive shaft, and lubrication station, forming a vibration molding system, a vacuum system, an automatic oil mist spraying system, a hydraulic control system, and an electrical control system. The automatic oil mist spraying system automatically sprays oil mist onto the inner wall of the mold at specific times through oil mist nozzles mounted on the mold box. However, this oil spraying method results in uneven oil distribution and still requires manual water spraying, leading to unsatisfactory cooling and cleaning effects. Summary of the Invention

[0004] In view of this, the present invention provides a carbon electrode forming machine, which aims to solve the technical problems of uneven oil spraying, poor demolding effect, and unsatisfactory cleaning and cooling effect of manual water spraying on the carbon electrode surface in the prior art.

[0005] To solve the above technical problems, the present invention provides a carbon electrode forming machine, including a frame, a pressure head disposed on the frame, an upper mold and a lower mold disposed below the frame, a spraying mechanism disposed inside the upper mold, a water tank disposed below the upper mold, a return box disposed below the lower mold, and a return pipe connected between the water tank and the return box. The spraying mechanism includes a cylinder, an oil spraying assembly and a water spraying assembly disposed on the cylinder. The cylinder includes a reinforcing ring and a plurality of unfolding plates hinged to the reinforcing ring. A pusher plate is provided inside the cylinder. The oil spraying assembly sprays oil into the cylinder, and the water spraying assembly sprays water into the cylinder. The oil spraying and water spraying are performed alternately.

[0006] By adopting the above technical solution, automatic alternating water and oil spraying can be achieved during the molding process of the carbon electrode. Before the ingredients are placed into the cylinder cavity, the push plate is located at the upper part of the cylinder, unfolding the unfolding plate. The oil spraying component sprays oil. As the push plate moves down, it scrapes the oil sprayed on the unfolding plate evenly. When the push plate moves to the lower part of the cylinder, the oil spraying ends, the water spraying component stores water, the ingredients are added into the cylinder, and the press head extrudes and molds the material. Then, the push plate moves up, pushing the carbon electrode out of the cylinder. During this process, the unfolding plate unfolds, and the water spraying component starts spraying water to clean and cool the surface of the carbon electrode. The water tank in the return box is filled with water by a water pump to meet the water spraying volume. This invention has multiple unfolding plates. The push plate evenly scrapes the sprayed oil onto the inner wall of the unfolding plate, which can prevent the material from sticking to the inner wall of the unfolding plate and facilitate demolding. This invention involves spraying oil before adding ingredients and spraying water when ejecting the carbon electrode. The oil and water spraying are performed alternately to meet the requirements of carbon electrode production. At the same time, manual oil and water spraying is not required. The oil spraying is uniform and the water spraying area is large, which has a good cleaning and cooling effect on the surface of the carbon electrode, thus improving production efficiency.

[0007] Specifically, the pusher plate has a frustum-shaped structure, and the unfolding plate is unfolded under the push of the pusher plate.

[0008] The fuel injection assembly includes an oil trough located at the lower part of the unfolding plate, an oil pipe located inside the unfolding plate, a limiting rod located at the upper part of the oil pipe, a pin located on the reinforcing ring, and a spring connecting the pin and the limiting rod. The limiting rod extends into the oil pipe, and a fuel injection port is located in the oil pipe near the limiting rod. The fuel injection port passes through the unfolding plate. An oil pump is located at the lower part of the oil pipe, and the oil pump delivers oil from the oil trough into the oil pipe. When the limiting rod rises, the fuel injection port opens; when the limiting rod falls, the fuel injection port closes.

[0009] The water spray assembly includes a water pipe mounted on the unfolding plate, a second limiting rod mounted on the upper part of the water pipe, and a water tank mounted on one side of the water pipe. The second limiting rod extends into the water pipe. A water outlet is provided on the water pipe near the second limiting rod, and the water outlet is connected to the water tank. A water spray nozzle is provided on the side of the water tank opposite to the water outlet. A water pump is provided below the water pipe. The water pump delivers water from the water tank to the water pipe. When the second limiting rod rises, the water outlet opens; when the second limiting rod falls, the water outlet closes.

[0010] The unfolding plate is equipped with a gear, and both the first and second limiting rods are equipped with gear rings. The gear is located between the first and second limiting rods and meshes with the gear rings to realize the raising and lowering of the first and second limiting rods.

[0011] The water nozzle is located at the edge of the unfolding plate. The water nozzle is provided with a collar. The water nozzles on two adjacent unfolding plates are nested together by the collar. When the unfolding plate is unfolded, the water in the water tank is sprayed out from the water nozzle.

[0012] By adopting the above technical solution, the pusher plate unfolds the unfolding plate from bottom to top. When the pusher plate reaches the top of the unfolding plate, the unfolding plate has its maximum unfolding angle. Spring 1 drives the limit rod 1 to move upward, opening the oil spray nozzle. Under the action of the oil pump, oil is sprayed from the spray nozzle onto the inner wall of the unfolding plate. The pusher plate moves downward, scraping the oil on the inner wall of the unfolding plate evenly. The unfolding plate contracts, spring 1 compresses, pushing the limit rod 1 downward. The limit rod 1 blocks the oil spray nozzle, stopping the oil spray. During the downward movement of the limit rod, the gear rotates, and the gear drives the second limit rod to move upward, opening the water outlet. Under the action of the water pump, oil enters the water tank from the water outlet, storing water in the tank. The water pump controls the water storage volume. When the pusher plate is at the bottom of the unfolding plate, the ingredients are added into the cylinder, and the press head extrudes and forms the material. After forming, the pusher plate pushes the carbon electrode upward. During this process, the unfolding plate opens, and the water spray nozzle between the two unfolding plates opens, spraying water from the nozzle to clean and cool the carbon electrode. After the carbon electrode is pushed out, the pusher plate is positioned at the top of the unfolding plate, and the oil spraying assembly is activated again to spray oil into the unfolding plate. This invention controls the switching between oil and water by opening and closing the unfolding plate. When spraying oil, water is not sprayed, and when spraying water, oil is not sprayed. This ensures even oil distribution while also cleaning and cooling the carbon electrode.

[0013] Preferably, the water tank is provided with a baffle, the baffle is connected to the water tank by a spring, the baffle is provided with a water inlet, and a corrugated pipe is connected between the water inlet and the water outlet.

[0014] By installing a baffle inside the water tank, the baffle moves as the water level in the tank increases, and the amount of water stored can be controlled according to the distance the baffle moves.

[0015] Additionally, a push rod is rotatably connected to one side of the lower mold, which pushes the upper and lower molds flat. The push rod pushes the lower mold, causing the upper mold to be pushed flat as well, making it easier for the push plate to push out the carbon electrode.

[0016] The beneficial effects of the above-described technical solution of the present invention are as follows: 1. This invention features multiple unfolding plates. When the plates unfold, the oil spray nozzles open, and oil is sprayed from the nozzles onto the inner wall of the unfolding plates. This eliminates the need for manual oil spraying, improving production efficiency and reducing labor costs.

[0017] 2. This invention opens or closes the unfolding plate by pushing the push plate. When the push plate is above the unfolding plate, oil is sprayed. When the push plate moves down, the sprayed oil is evenly scraped onto the inner wall of the unfolding plate, which can prevent the material from sticking to the inner wall of the unfolding plate and facilitate demolding.

[0018] 3. When the push plate of this invention moves to the bottom of the unfolding plate, the water inlet opens and water is stored in the water tank. After extrusion molding, the push plate pushes out the carbon electrode while the unfolding plate unfolds, and water is sprayed out from the spray nozzle to clean and cool the carbon electrode. This invention is equipped with multiple unfolding plates and multiple spray nozzles, which can spray water on the carbon electrode at the same time, and has a better cleaning and cooling effect.

[0019] 4. This invention sprays oil before adding ingredients and sprays water when pushing out the carbon electrode. The switching between oil and water is controlled by opening and closing the unfolding plate. When spraying oil, water is not sprayed, and when spraying water, oil is not sprayed. This can evenly distribute oil and clean and cool the carbon electrode, thereby improving the product qualification rate and production efficiency. Attached Figure Description

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of the present invention. Figure 1-7 The technical solutions of the embodiments of the present invention will be clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention are within the scope of protection of the present invention.

[0023] Example like Figures 1-2 As shown, this embodiment provides a carbon electrode forming machine, including a frame 2, a pressure head 1 disposed on the frame 2, an upper mold 3 and a lower mold 5 disposed below the frame 2, a spraying mechanism disposed inside the upper mold 3, a water tank 4 disposed below the upper mold 3, a return box 6 disposed below the lower mold 5, and a return pipe 8 connecting the water tank 4 and the return box 6. The spraying mechanism includes a cylinder, an oil spraying assembly and a water spraying assembly mounted on the cylinder, such as... Figure 3 As shown, the cylinder includes a reinforcing ring 9 and multiple unfolding plates 10 hinged to the reinforcing ring 9. A pusher plate 11 is provided inside the cylinder. An oil spraying assembly sprays oil into the cylinder, and a water spraying assembly sprays water into the cylinder. The oil spraying and water spraying alternate. In this embodiment, the unfolding plates 10 are arc-shaped and are set to three. Of course, other numbers can also be used. The return tank 6 is provided with an outlet. Water is injected into the return tank 6 through the outlet. The water in the return tank 6 stores water in the water tank 4 through the return pipe 8. When the water storage capacity is reached, the water in the return tank 6 flows out through the outlet.

[0024] Specifically, the push plate 11 has a frustum-shaped structure. The unfolding plate 10 is unfolded by the push plate 11. The push plate 11 is raised and lowered by the help of a hydraulic cylinder or other external force.

[0025] like Figure 4 and Figure 7 As shown, the fuel injection assembly includes an oil trough 12 located at the lower part of the unfolding plate 10, an oil pipe 17 located within the unfolding plate 10, a limiting rod 15 located at the upper part of the oil pipe 17, a pin 13 located on the reinforcing ring 9, and a spring 14 connecting the pin 13 and the limiting rod 15. The limiting rod 15 extends into the oil pipe 17, and a fuel injection port is located near the limiting rod 15 within the oil pipe 17. The fuel injection port passes through the unfolding plate 10. An oil pump is located at the lower part of the oil pipe 17, and the oil pump delivers oil from the oil trough 12 into the oil pipe 17. When the limiting rod 15 rises, the fuel injection port opens; when the limiting rod 15 falls, the fuel injection port closes. The reinforcing ring 9 has a round hole, and the end of the pin 13 has a rounded corner, which is engaged in the round hole, allowing it to rotate.

[0026] like Figures 4-6 As shown, the water spray assembly includes a water pipe 18 mounted on the unfolding plate 10, a limiting rod 21 mounted on the upper part of the water pipe 18, and a water tank 23 mounted on one side of the water pipe 18. The limiting rod 21 extends into the water pipe 18. An outlet is located on the water pipe 18 near the limiting rod 21, and the outlet is connected to the water tank 23. A spray nozzle is located on the side of the water tank 23 opposite to the outlet. A water pump is located below the water pipe 18, and the pump delivers water from the water tank 4 to the water pipe 18. When the limiting rod 21 rises, the outlet opens; when the limiting rod 21 falls, the outlet closes. Multiple spray nozzles can be provided, allowing simultaneous water spraying onto the carbon electrode. The water pipe 18, water tank 23, and oil pipe 17 are all located inside the unfolding plate 10.

[0027] like Figure 4 As shown, the unfolding plate 10 is equipped with a gear 16, and both the first limiting rod 15 and the second limiting rod 21 are equipped with gear rings. The gear 16 is located between the first limiting rod 15 and the second limiting rod 21. The gear 16 meshes with the gear rings to realize the lifting and lowering of the first limiting rod 15 and the second limiting rod 21.

[0028] like Figure 4 As shown, the water nozzle is located at the edge of the unfolding plate 10, and a collar 24 is provided on the water nozzle. The water nozzles on two adjacent unfolding plates 10 are nested together by the collar 24. When the unfolding plate 10 is unfolded, the water in the water tank 23 is sprayed out from the water nozzle. When the unfolding plate 10 is closed, the two adjacent water nozzles are nested together by the collar 24, and the water nozzle is closed. When the unfolding plate 10 is unfolded, the collar 24 is no longer nested, and the water in the water tank 23 is sprayed out from the water nozzle.

[0029] By adopting the above technical solution, automatic alternating water and oil spraying can be achieved during the carbon electrode forming process. Before the ingredients are placed into the cylinder cavity, the push plate 11 is located at the upper part of the cylinder, unfolding the unfolding plate 10, raising the limiting rod 15, opening the oil spray nozzle, and spraying oil into the unfolding plate 10. As the push plate 11 moves down, it scrapes the oil sprayed on the unfolding plate 10 evenly. When the push plate 11 moves to the lower part of the cylinder, the unfolding plate 10 closes, the limiting rod 15 descends, sealing the oil spray nozzle, and the oil spraying ends. At the same time, the limiting rod 21 rises, the water outlet opens, and water is stored in the water tank 23. The ingredients are added into the cylinder, and the press head 1 extrudes and forms the carbon electrode. Then, the push plate 11 moves up, pushing the carbon electrode out of the cylinder. During this process, the unfolding plate 10 unfolds, the water spray nozzle opens, and water spraying begins to clean and cool the surface of the carbon electrode. The return box 6 stores water in the water tank 4 through a water pump to meet the water spraying volume. This invention features multiple unfolding plates 10. Push plates 11 evenly scrape the sprayed oil onto the inner wall of the unfolding plates 10, preventing material from sticking to the inner wall and facilitating demolding. This invention performs oil spraying before adding ingredients and water spraying when ejecting the carbon electrode. The alternating oil and water spraying meets the requirements of carbon electrode production. Furthermore, it eliminates the need for manual oil and water spraying, provides uniform oil spraying, and covers a large water spraying area, resulting in excellent cleaning and cooling effects on the carbon electrode surface, thus improving production efficiency.

[0030] As a preferred embodiment of the present invention, such as Figure 4 As shown, a baffle 19 is provided inside the water tank 23. The baffle 19 is connected to the water tank 23 by a spring 20. The baffle 19 is provided with a water inlet, and a corrugated pipe 22 is connected between the water inlet and the water outlet.

[0031] By installing a baffle 19 inside the water tank 23, the baffle 19 is pushed to move as the water volume in the water tank 23 increases. The amount of water stored can be controlled according to the distance the baffle 19 moves.

[0032] As a preferred embodiment of the present invention, such as Figure 1 As shown, a push rod 7 is rotatably connected to one side of the lower mold 5. The push rod 7 pushes the upper mold 3 and the lower mold 5 flat. The push rod 7 pushes the lower mold 5, causing the upper mold 3 to be pushed horizontally together, so that the push plate 11 can push out the carbon electrode.

[0033] How to use this invention: S1: Push the push plate 11 to the upper end of the unfolding plate 10, unfolding the plate 10 unfolds, the spring 14 drives the limit rod 15 to move upward, the oil injection port opens, and under the action of the oil pump, oil is sprayed out from the oil injection port along the oil pipe 17 and sprayed onto the inner wall of the unfolding plate 10. The push plate 11 moves downward to scrape the oil on the inner wall of the unfolding plate 10 evenly. The unfolding plate 10 retracts, the spring 14 is compressed, and the limit rod 15 is pushed downward. The limit rod 15 blocks the oil injection port and stops the oil injection. S2: During the downward movement of limit rod 15, it drives gear 16 to rotate. Gear 16 drives limit rod 21 to move upward, opening the water outlet. Under the action of the water pump, water enters the water tank 23 from the water outlet along the water pipe 18, storing water in the water tank 23. Observe the water storage amount according to the distance the baffle 19 moves. S3: When the push plate 11 is at the bottom of the unfolding plate 10, the ingredients are added into the cylinder and the press head 1 is used to extrude and form the material. After forming, the push rod 7 pushes the lower mold 5 and drives the upper mold 3 to be pushed to the horizontal direction. The push plate 11 pushes out the carbon electrode. During this process, the unfolding plate 10 opens and the water spray nozzle between the two unfolding plates 10 opens. Water sprays out from the water spray nozzle to clean and cool the carbon electrode. S4: After the carbon electrode is pushed out, the push plate 11 is located at the top of the unfolding plate 10. The push rod 7 pushes the lower mold 5, which in turn pushes the upper mold 3 to the vertical direction. The oil spraying assembly is started again to spray oil into the unfolding plate 10 to make the next carbon electrode.

[0034] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0035] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
