Description

Technical Field

[0001] This utility model relates to the technical field of graphite electrode rod production equipment, and more specifically to a graphite electrode rod straightening device. Background Technology

[0002] Graphite electrodes are high-temperature resistant graphitic conductive materials made from petroleum coke and pitch coke as aggregates and coal tar pitch as binders through processes such as calcination, crushing and grinding, batching, mixing, molding, baking, impregnation, graphitization, and machining. They are called artificial graphite electrodes (or simply graphite electrodes) to distinguish them from natural graphite electrodes made from natural graphite.

[0003] During the processing of graphite electrode raw products, drilling and thread cutting are required. Since graphite electrode raw products are relatively heavy, the traditional method is to use hoisting tools to hoist and fix them and adjust the center position of the raw products. This method has poor positioning effect and requires manual assistance for correction, which increases the difficulty of positioning.

[0004] Therefore, how to provide a device that can straighten graphite electrodes, ensure the alignment of the graphite electrode axis during production, and guarantee the performance and safety of the graphite electrodes, is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides a graphite electrode rod straightening device, which aims to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A graphite electrode rod straightening device, comprising: A receiving plate, which is used to receive the straightened graphite electrode rods; A straightening assembly includes a flap, a first roller, a second roller, and a drive component. The rear end of the flap is hinged to the end of the receiving plate along the conveying direction, and the front end is used to connect to the discharge end of the graphite electrode rod production line. The first roller and the second roller are arranged in parallel and rotatably connected to the front and rear ends of the flap, with a rolling gap between them to receive the newly formed graphite electrode rod. The drive component is driven to rotate the first roller and the second roller to straighten the graphite electrode rod it receives. A pull rope is provided, one end of which is fixed to the end of the flap that is away from the receiving plate, and the other end is connected to a winding device. The winding device can wind up the pull rope to pull the flap to rotate and transport the cooled and straightened graphite electrode rod to the receiving plate.

[0007] The beneficial effects of this utility model are that the newly formed high-temperature graphite electrode rod is placed in the rolling gap between the first roller and the second roller. The rotation of the first roller and the second roller can drive the graphite electrode rod to roll. As the rolling time increases, the temperature of the graphite electrode decreases. At the same time, the rolling makes the axis of the graphite electrode rod more aligned. When the temperature of the graphite electrode rod decreases, the flip plate is lifted a certain distance by pulling the pull rope. At this time, due to the tilt angle, the graphite electrode rod will automatically roll onto the receiving plate, thereby packing and collecting it.

[0008] Preferably, it further includes a support column; the winder is fixed to the top surface of the take-up plate; the lower end of the support column is vertically fixed to the top surface of the take-up plate relative to the winder and the flapper; one end of the pull rope passes over the top of the support column and is fixed to the turntable of the winder. By supporting the pull rope with the support column, the output power of the winder can be reduced, and the pull rope can more easily pull the flapper to raise it.

[0009] Preferably, there are two flaps, which are symmetrically arranged on both sides of the front end of the receiving plate. Using two flaps ensures the stability of the rotation of the first and second roller shafts.

[0010] Preferably, the driving component includes a motor, a driving chain, and a driven chain. A driving gear is fixed to the output shaft of the motor. A rotating shaft is fixed to one end of both the first and second roller shafts, passing through the flap and corresponding to the driving gear. A transmission gear is fixed to the end of the rotating shaft. The driving chain bypasses the driving gear and the transmission gear located on the first roller shaft. The driven chain bypasses the second roller shaft and the transmission gear on the first roller shaft. The motor drives the first and second roller shafts to rotate synchronously via the chain drive.

[0011] Preferably, the first roller shaft has two drive gears. This ensures that the driving chain and the driven chain can be effectively installed.

[0012] Preferably, a receiving groove is provided on one side of the front end of the receiving plate panel, and both the driving chain and the driven chain are located in the receiving groove. This results in a more compact and simple structure that does not affect the collection of the graphite electrode rods.

[0013] Preferably, it also includes a baffle, with both ends of one side panel of the baffle fixed to the front ends of the two flip plates away from the receiving plate. The baffle can prevent the graphite electrode rod from falling out of the rolling gap due to the high rotation speed of the first and second rollers when the flip plates are pulled.

[0014] Preferably, the assembly also includes a transfer plate. The receiving plate has a straightening component mounting area at its front end. The transfer plate is located in front of the straightening component mounting area, and its two ends are fixed to the front ends of the receiving plate. The connection of the transfer plate corresponds to the discharge end of the graphite electrode rod production line. The graphite electrode rods are received by the transfer plate, and they can automatically roll into the rolling gap.

[0015] Preferably, the rear end of the transfer plate has a sloping surface that connects to the rolling gap.

[0016] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a graphite electrode rod straightening device, which straightens and cools the graphite electrode rod by continuously rolling it between the first roller and the second roller. Pulling the pull rope can raise the flip plate to collect the graphite electrode rod. The use of this device effectively ensures the alignment of the axis of the graphite electrode rod during production, thus ensuring the performance and safety of the graphite electrode rod.

[0020] 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.

[0021] This utility model embodiment discloses a graphite electrode rod straightening device, comprising: Receiving plate 1 is used to receive the straightened graphite electrode rods. The straightening assembly includes a flap 11, a first roller 4 and a second roller 5, and a drive component. The rear end of the flap 11 is hinged to the end of the receiving plate 1 along the conveying direction, and the front end is used to connect to the discharge end of the graphite electrode rod production line. The first roller 4 and the second roller 5 are arranged in parallel and rotatably connected to the front and rear ends of the flap 11, and there is a rolling gap between them to receive the newly formed graphite electrode rod. The drive component is connected to the first roller 4 and the second roller 5 to drive them to rotate and straighten the graphite electrode rod they receive. A pull rope 12 is attached to one end of a flap 11 away from the receiving plate 1, and the other end is connected to a winder 14. The winder 14 can wind up the pull rope 12 to pull the flap 11 to rotate and transport the cooled and straightened graphite electrode rod to the receiving plate 1.

[0022] In this embodiment, there are two flip plates 11, which are symmetrically arranged on both sides of the front end of the receiving plate 1.

[0023] like Figure 1 and 2 As shown, the flaps are hinged to the front end of the receiving plate. The two flaps are arranged symmetrically with their panels perpendicular to the receiving plate. A first roller and a second roller are rotatably connected between the two flaps. Through the synchronous rotation of the first roller and the second roller, the graphite electrode rod can continuously roll along the rolling gap between the first roller and the second roller. The continuous rolling of the graphite electrode rod ensures that its axis is aligned under high temperature conditions by using rolling force. On the other hand, the continuous rolling allows it to cool down naturally. After the temperature of the graphite electrode rod drops, the end of the flap relative to the second roller is lifted by pulling the pull rope, allowing the graphite electrode rod to roll onto the receiving plate for collection.

[0024] To further optimize the above technical solution and ensure that the pull rope can effectively pull the flip plate, a support column 13 is also included; the winder 14 is fixed on the top surface of the take-up plate 1; the lower end of the support column 13 is vertically fixed on the top surface of the take-up plate 1 relative to the winder 14 and the flip plate 11; one end of the pull rope 12 passes around the top of the support column 13 and is fixed to the turntable of the winder 14.

[0025] The winder can wind up the pull rope, which is connected to the support column to ensure that the pull rope can pull the flap to lift it up.

[0026] In some other specific embodiments, to ensure the effective operation of the pull rope, the top of the support column is rotatably connected to a roller with a groove, and the pull rope can slide along the groove of the roller.

[0027] In some other specific embodiments, the winding device can be replaced by a hydraulic cylinder, and the end of the pull rope away from the flap can be fixed to the piston rod of the hydraulic cylinder. The extension and retraction of the piston rod of the hydraulic cylinder drives the pull rope to pull the flap.

[0028] To further optimize the above technical solution and ensure the synchronous rotation of the first and second roller shafts, the driving components include a motor 7, a driving chain 8, and a driven chain 9. The output shaft of the motor 7 is fixed with a driving gear. One end of both the first roller shaft 4 and the second roller shaft 5 is fixed with a rotating shaft, which passes through the flap 11 and corresponds to the driving gear. A transmission gear is fixed to the end of the rotating shaft. The driving chain 8 passes around the driving gear and the transmission gear located on the first roller shaft 4. The driven chain 9 passes around the second roller shaft 5 and the transmission gear on the first roller shaft 4. The first roller shaft 4 has two transmission gears.

[0029] like Figure 3 As shown, the motor drives the first roller shaft to rotate through the active chain, and the first roller shaft and the second roller shaft rotate synchronously through the driven chain.

[0030] To further optimize the above technical solution, a servo motor can be used to adjust the rotation speed of the first and second roller shafts.

[0031] To further optimize the above technical solution and ensure the compactness of the device structure, a receiving groove 10 is provided on one side of the front end of the receiving plate 1 panel, and the driving chain 8 and the driven chain 9 are both located in the receiving groove 10.

[0032] In some other specific embodiments, a baffle 6 is also included, with both ends of one side panel of the baffle 6 fixed to the front ends of the two flip plates 11 away from the receiving plate 1.

[0033] The baffle panel corresponds to the side of the receiving plate. The baffle and the flip plate are fixed on the side away from the receiving plate. When the flip plate is lifted, the baffle can be lifted synchronously to prevent the graphite electrode rod from sliding down the side away from the receiving plate due to the high rolling speed.

[0034] To further optimize the above technical solution, a transfer plate 3 is also included. The front end of the receiving plate 1 is provided with a straightening component installation area. The transfer plate 3 is located in front of the straightening component installation area and its two ends are fixed to the front ends of the receiving plate 1. The connection of the transfer plate 3 corresponds to the discharge end of the graphite electrode rod production line.

[0035] The transfer plate receives the produced high-temperature graphite electrode rods, which can then roll along the transfer plate into the rolling gap.

[0036] To further optimize the above technical solution, the high-temperature graphite electrode rod is replaced with a rotating plate 3 with a slope at one end relative to the second roller shaft 5.

[0037] In some other specific embodiments, a pad is fixed below the transfer plate. The size of the pad is larger than that of the transfer plate. The transfer plate is raised by the pad so that the top surface of the pad corresponds to the upper edge of the flip plate.

[0038] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since it corresponds to the method disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
