Description

Technical Field

[0001] The present invention relates to the technical field of lubricating powder processing, and specifically relates to a lubricating powder screening device that can prevent screen blockage. Background Art

[0002] Lubricating powder is a solid lubricating material, usually made of graphite, quartz, talc, metal powder, etc. Its main function is to reduce friction and wear between machine parts, prevent jamming and rust, and is especially suitable for high-temperature, high-pressure and high-speed environments, such as aeroengines, automotive engines, oil drilling rigs, metal processing equipment, etc.

[0003] Patent No. 202020725190.4 discloses a screening device for lubricating powder raw materials. The lubricating powder raw materials on the screen of this device will fall onto the inner wall of the bottom of the housing through the screen, making the screening more uniform.

[0004] However, when the existing screening device for lubricating powder raw materials is in use, the lubricating powder raw materials are screened through the screen. However, some of the lubricating powder raw materials have larger specifications. When the lubricating powder raw materials with larger specifications pass through the screen, they will get stuck inside the screen. Only driving the screen to vibrate cannot take out the lubricating powder raw materials stuck inside the screen, which easily causes blockage of the screen for screening lubricating powder raw materials and has a certain impact on the screening efficiency of the lubricating powder raw materials. Therefore, a lubricating powder screening device that can prevent screen blockage is provided. Summary of the Invention

[0005] The main purpose of the present invention is to provide a lubricating powder screening device that can prevent screen blockage. The present invention solves the problems that the screen of the existing screening device for lubricating powder raw materials is prone to blockage and the screening efficiency of the lubricating powder raw materials is low by setting a servo motor, a rope chain, a storage tray, a fixing plate, a support block, a fixing hole and a driving rod.

[0006] The technical solution adopted by the present invention to solve its technical problems is a lubricating powder screening device that can prevent screen blockage, including a tank body. A servo motor that provides power is bolted inside the tank body, and a driving rod is key-connected to the power output end of the servo motor. A screen frame for placing lubricating powder raw materials is welded to the end of the driving rod away from the servo motor. A screen for screening lubricating powder raw materials is screwed to the bottom of the screen frame. A storage tray is sleeved outside the driving rod, and a rope chain is wound around the outside of the storage tray. One end of the rope chain away from the storage tray is screwed to a fixing plate. A support block that enters the screen is welded to the outside of the fixing plate. Fixing holes for allowing the lubricating powder to move downward are formed on the surface of the fixing plate, and the number of the fixing holes is several.

[0007] By adopting the above technical solution, when the lubricating powder raw material is placed in the sieve frame inside the tank, the servo motor inside the tank converts the received electric energy into mechanical energy under the action of an external controller. The servo motor drives the driving rod to rotate clockwise, and then the driving rod drives the sieve frame to rotate, so that the sieve mesh at the bottom of the sieve frame screens the lubricating powder raw material;

[0008] When the sieve mesh at the bottom of the sieve frame screens the lubricating powder raw material, the receiving disc outside the driving rod drives the rope chain to wind up. Subsequently, the rope chain drives the fixed plate to move, and there are two groups of receiving discs and rope chains outside the driving rod, so that the fixed plate moves upward. Then, the supporting block on the fixed plate enters the inside of the sieve mesh, so that the lubricating powder raw material stuck in the sieve mesh is pushed out. Subsequently, the servo motor drives the driving rod to rotate counterclockwise under the action of the external controller, so that the receiving disc outside the driving rod drives the rope chain to unwind, and the rope chain drives the fixed plate to separate from the sieve mesh, thus preventing the sieve mesh for screening the lubricating powder raw material from being blocked;

[0009] When the supporting block on the fixed plate enters the sieve mesh, the fixed plate contacts the surface of the sieve mesh, causing vibration of the fixed plate, so that the lubricating powder raw material on the fixed plate falls off. At the same time, several fixing holes opened on the surface of the fixed plate enable the lubricating powder raw material falling on the fixed plate to move downward, thus facilitating the removal of the lubricating powder raw material on the fixed plate.

[0010] Specifically, a bracket for supporting the tank is bolted to the outside of the tank, and a cylinder for providing power is bolted to the outside of the bracket. The power output end of the cylinder is screwed and fixed with a top cover that contacts the top of the tank.

[0011] By adopting the above technical solution, when the lubricating powder raw material needs to be put into the tank, the cylinder outside the bracket drives the top cover to move under the action of the external controller. Subsequently, the top cover separates from the tank, thus facilitating the putting of the lubricating powder raw material into the sieve frame inside the tank.

[0012] Specifically, a bottom tank for collecting the screened lubricating powder is bolted to the bottom of the tank, and a bottom cover for taking out the screened lubricating powder is threadedly connected to the bottom of the bottom tank.

[0013] By adopting the above technical solution, when the sieve mesh at the bottom of the sieve frame screens the lubricating powder raw material, the screened lubricating powder raw material falls into the bottom tank at the bottom of the tank, and the bottom of the bottom tank is inclined inward. Then, the bottom cover at the bottom of the bottom tank is rotated, so that the bottom cover separates from the bottom tank, thus facilitating the taking out of the screened lubricating powder raw material.

[0014] Specifically, a pulley A and a pulley B for moving the rope chain are rotatably connected inside the tank, and pulley A is located above pulley B.

[0015] By adopting the above technical solution, when the rope chain drives the fixed plate to move, the rope chain slides inside pulley A and pulley B installed in the tank, improving the stability of the movement of the rope chain.

[0016] Specifically, connection blocks are welded to the outside of the sieve frame, and connection grooves for the sliding of the connection blocks are provided on the inner side of the tank body.

[0017] By adopting the above technical solution, when the driving rod drives the sieve frame to rotate, the connection blocks welded to the outside of the sieve frame slide in the connection grooves provided in the tank body, improving the stability of the rotation of the sieve frame.

[0018] Specifically, the input ends of the air cylinder and the servo motor are both electrically connected to the power supply end of an external power supply.

[0019] By adopting the above technical solution, by connecting to an external power supply, the electrical equipment works normally.

[0020] Advantages of the present invention:

[0021] (1) For the lubricating powder screening equipment capable of preventing sieve mesh blockage according to the present invention, when the sieve mesh at the bottom of the sieve frame screens the lubricating powder raw material, the storage disc outside the driving rod drives the rope chain to wind up. Subsequently, the rope chain drives the fixed plate to move, and there are two groups of the storage disc and the rope chain outside the driving rod, so that the fixed plate moves upward. Then, the support blocks on the fixed plate enter the inside of the sieve mesh, so that the lubricating powder raw material stuck in the sieve mesh is pushed out. Subsequently, the servo motor drives the driving rod to rotate counterclockwise under the action of an external controller, so that the storage disc outside the driving rod drives the rope chain to unwind, and the rope chain drives the fixed plate to separate from the sieve mesh, thereby preventing the sieve mesh for screening the lubricating powder raw material from being blocked.

[0022] (2) For the lubricating powder screening equipment capable of preventing sieve mesh blockage according to the present invention, when the support blocks on the fixed plate enter the sieve mesh, the fixed plate contacts the surface of the sieve mesh, causing vibration of the fixed plate, so that the lubricating powder raw material on the fixed plate vibrates and falls off. At the same time, several fixing holes provided on the surface of the fixed plate enable the lubricating powder raw material falling on the fixed plate to move downward, thereby facilitating the removal of the lubricating powder raw material on the fixed plate.

[0027] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0028] In order to avoid clogging of the sieve mesh 19 for screening lubricating powder raw materials, as an embodiment of the present invention, as Figure 1 、 Figure 2 shown, a lubricating powder screening device capable of preventing sieve mesh clogging according to the present invention includes a tank body 2, a servo motor 7 providing power is bolted inside the tank body 2, and a driving rod 15 is key-connected to the power output end of the servo motor 7. A sieve frame 17 for placing lubricating powder raw materials is welded to the end of the driving rod 15 away from the servo motor 7. A sieve mesh 19 for screening lubricating powder raw materials is screwed to the bottom of the sieve frame 17. A storage tray 16 is sleeved outside the driving rod 15, and a rope chain 9 is wound around the outside of the storage tray 16. One end of the rope chain 9 away from the storage tray 16 is screwed to a fixed plate 14. A support block 13 entering the sieve mesh 19 is welded to the outside of the fixed plate 14. A fixed hole 18 for allowing the lubricating powder to move downward is formed on the surface of the fixed plate 14, and the number of the fixed holes 18 is several.

[0029] During use, when the lubricating powder raw materials are placed in the sieve frame 17 inside the tank body 2, the servo motor 7 inside the tank body 2 converts the received electric energy into mechanical energy under the action of an external controller. The servo motor 7 drives the driving rod 15 to rotate clockwise, and then the driving rod 15 drives the sieve frame 17 to rotate, so that the sieve mesh 19 at the bottom of the sieve frame 17 screens the lubricating powder raw materials;

[0030] When the sieve mesh 19 at the bottom of the sieve frame 17 screens the lubricating powder raw materials, the storage tray 16 outside the driving rod 15 drives the rope chain 9 to wind up. Subsequently, the rope chain 9 drives the fixed plate 14 to move. Both the storage tray 16 outside the driving rod 15 and the rope chain 9 are provided with two groups, so that the fixed plate 14 moves upward. Then the support block 13 on the fixed plate 14 enters the inside of the sieve mesh 19, so that the lubricating powder raw materials stuck in the sieve mesh 19 are ejected. Subsequently, the servo motor 7 drives the driving rod 15 to rotate counterclockwise under the action of an external controller, so that the storage tray 16 outside the driving rod 15 drives the rope chain 9 to unwind, and the rope chain 9 drives the fixed plate 14 to separate from the sieve mesh 19, thereby avoiding clogging of the sieve mesh 19 for screening lubricating powder raw materials;

[0031] When the support block 13 on the fixed plate 14 enters the screen 19, the fixed plate 14 contacts the surface of the screen 19, so that the vibration generated by the fixed plate 14 causes the lubricating powder raw material on the fixed plate 14 to fall off, and at the same time, a plurality of fixed holes 18 opened on the surface of the fixed plate 14 cause the lubricating powder raw material fallen on the fixed plate 14 to move downward, thereby facilitating the removal of the lubricating powder raw material on the fixed plate 14.

[0032] In order to put the lubricating powder raw material into the screen frame 17 in the tank body 2, illustratively, as Figure 1 As shown, the present invention also includes that the tank body 2 is externally bolted to a bracket 5 for supporting the tank body 2, and the bracket 5 is externally bolted to a cylinder 3 for providing power, and the power output end of the cylinder 3 is screwed to fix a top cover 1 in contact with the top of the tank body 2.

[0033] During use, when the lubricating powder raw material is to be placed in the tank body 2, the cylinder 3 outside the bracket 5 is driven by the external controller to move the top cover 1, and then the top cover 1 is separated from the tank body 2, so as to facilitate the placement of the lubricating powder raw material into the screen frame 17 in the tank body 2.

[0034] In order to take out the sieved lubricating powder raw material, exemplary, as Figure 2 As shown, the present invention also includes that the bottom of the tank body 2 is bolted to a bottom tank 6 for collecting the sieved lubricating powder, and the bottom of the bottom tank 6 is threadedly connected to a bottom cover 4 for taking out the sieved lubricating powder.

[0035] When in use, when the screen 19 at the bottom of the screen frame 17 screens the lubricating powder raw material, the screened lubricating powder raw material falls into the bottom tank 6 at the bottom of the tank body 2, and the bottom of the bottom tank 6 is tilted inward, and then the bottom cover 4 at the bottom of the bottom tank 6 is rotated to separate the bottom cover 4 from the bottom tank 6, thereby facilitating the removal of the screened lubricating powder raw material.

[0036] In order to improve the stability of the movement of the rope chain 9, for example, Figure 2 As shown, the present invention also includes that the tank body 2 is rotatably connected with a pulley A8 and a pulley B12 for moving the rope chain 9, and the pulley A8 is located on the upper side of the pulley B12.

[0037] When in use, when the rope chain 9 drives the fixed plate 14 to move, the rope chain 9 slides in the pulley A8 and the pulley B12 installed in the tank body 2, thereby improving the stability of the movement of the rope chain 9.

[0038] In order to improve the stability of the rotation of the screen frame 17, exemplary, as Figure 2 As shown, the present invention further includes that a connection block 10 is welded to the outside of the sieve frame 17, and a connection groove 11 for sliding the connection block 10 is opened on the inside of the tank body 2.

[0039] During use, when the driving rod 15 drives the sieve frame 17 to rotate, the connecting block 10 welded outside the sieve frame 17 slides in the connecting groove 11 opened in the tank body 2, improving the stability of the rotation of the sieve frame 17.

[0040] For the electrical equipment to work properly, by way of example, such as Figure 1 、 Figure 2 As shown, the present invention further includes that the input ends of the cylinder 3 and the servo motor 7 are both electrically connected to the power supply end of an external power source.

[0041] During use, by connecting to an external power source, the electrical equipment works properly.

[0042] When the lubricating powder raw material is put into the sieve frame 17 in the tank body 2 during use of the present invention, the servo motor 7 in the tank body 2 converts the received electrical energy into mechanical energy under the action of an external controller. The servo motor 7 drives the driving rod 15 to rotate clockwise, and then the driving rod 15 drives the sieve frame 17 to rotate, so that the sieve mesh 19 at the bottom of the sieve frame 17 screens the lubricating powder raw material;

[0043] When the sieve mesh 19 at the bottom of the sieve frame 17 screens the lubricating powder raw material, the receiving disc 16 outside the driving rod 15 drives the rope chain 9 to wind up. Subsequently, the rope chain 9 drives the fixed plate 14 to move. And there are two groups of the receiving disc 16 outside the driving rod 15 and the rope chain 9, so that the fixed plate 14 moves upward. Then the supporting block 13 on the fixed plate 14 enters the inside of the sieve mesh 19, so that the lubricating powder raw material stuck in the sieve mesh 19 is pushed out. Subsequently, the servo motor 7 drives the driving rod 15 to rotate counterclockwise under the action of an external controller, so that the receiving disc 16 outside the driving rod 15 drives the rope chain 9 to unwind, and the rope chain 9 drives the fixed plate 14 to separate from the sieve mesh 19, thus preventing the sieve mesh 19 for screening the lubricating powder raw material from being blocked;

[0044] When the supporting block 13 on the fixed plate 14 enters the sieve mesh 19, the fixed plate 14 contacts the surface of the sieve mesh 19, causing vibration of the fixed plate 14, so that the lubricating powder raw material on the fixed plate 14 shakes off. At the same time, several fixing holes 18 opened on the surface of the fixed plate 14 enable the lubricating powder raw material falling on the fixed plate 14 to move downward, thus facilitating the removal of the lubricating powder raw material on the fixed plate 14;

[0045] When the lubricating powder raw material is to be put into the tank body 2, the cylinder 3 outside the bracket 5 drives the top cover 1 to move under the action of an external controller. Subsequently, the top cover 1 separates from the tank body 2, thus facilitating the putting of the lubricating powder raw material into the sieve frame 17 in the tank body 2;

[0046] When the sieve mesh 19 at the bottom of the sieve frame 17 screens the lubricating powder raw material, the screened lubricating powder raw material falls into the bottom tank 6 at the bottom of the tank body 2, and the bottom of the bottom tank 6 inclines inward. Then rotate the bottom cover 4 at the bottom of the bottom tank 6, so that the bottom cover 4 separates from the bottom tank 6, thus facilitating the taking out of the screened lubricating powder raw material;

[0047] When the rope chain 9 drives the fixed plate 14 to move, the rope chain 9 slides within the pulley A8 and pulley B12 installed in the tank body 2, improving the stability of the movement of the rope chain 9;

[0048] When the drive rod 15 drives the sieve frame 17 to rotate, the connecting block 10 welded outside the sieve frame 17 slides within the connecting groove 11 opened in the tank body 2, improving the stability of the rotation of the sieve frame 17.

[0049] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments.
