Description

Technical Field

[0001] This utility model relates to the field of lubricating powder processing technology, specifically to a raw material screening device for lubricating powder processing. Background Technology

[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 corrosion, and is particularly suitable for high temperature, high pressure and high speed environments, such as aircraft engines, automobile 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 the device will fall onto the bottom inner wall of the outer shell, making the screening more uniform.

[0004] However, when using existing lubricating powder raw material screening devices, the lubricating powder raw materials are screened through a screen. However, some of the lubricating powder raw materials contain larger-sized materials. When the larger-sized lubricating powder raw materials pass through the screen, they will get stuck inside the screen. Vibrating the screen alone cannot remove the lubricating powder raw materials stuck inside the screen, which can easily cause screen blockage and affect the screening efficiency of the lubricating powder raw materials. Therefore, a raw material screening device for lubricating powder processing is designed. Utility Model Content

[0005] The main purpose of this invention is to provide a raw material screening device for lubricating powder processing. This invention solves the problem of easy clogging of the screen and low screening efficiency of lubricating powder raw materials in existing screening devices by setting a servo motor, rope chain, storage tray, fixing plate, support block, fixing hole and drive rod.

[0006] The technical solution adopted by this utility model to solve its technical problem is a raw material screening device for lubricating powder processing, including a tank. A servo motor for providing power is bolted inside the tank, and a drive rod is keyed 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 drive rod away from the servo motor. A screen mesh for screening the lubricating powder raw materials is fixed to the bottom of the screen frame with screws. A receiving tray is sleeved on the outside of the drive rod, and a rope chain is wound around the outside of the receiving tray. A fixing plate is fixed to the end of the rope chain away from the receiving tray with screws. A support block that enters the screen mesh is welded to the outside of the fixing plate. The surface of the fixing plate has a number of fixing holes for moving the lubricating powder downwards.

[0007] By adopting the above technical solution, when the lubricating powder raw material is put into the screen frame inside the tank, the servo motor inside the tank is converted into mechanical energy by the external controller. The servo motor drives the drive rod to rotate clockwise, and then the drive rod drives the screen frame to rotate, so that the screen at the bottom of the screen frame can screen the lubricating powder raw material.

[0008] When the screen at the bottom of the screen frame screens the lubricating powder raw material, the receiving disc outside the drive rod drives the rope chain to wind up. Then the rope chain drives the fixed plate to move. There are two sets of receiving discs and rope chains outside the drive rod, which makes the fixed plate move upward. Then the support block on the fixed plate enters the screen, which pushes out the lubricating powder raw material stuck in the screen. Then the servo motor, driven by the external controller, drives the drive rod to rotate counterclockwise, which causes the receiving disc outside the drive rod to wind up the rope chain. The rope chain drives the fixed plate to separate from the screen, thereby avoiding the screen for screening lubricating powder raw material from becoming clogged.

[0009] When the support block on the fixed plate enters the screen, the fixed plate comes into contact with the screen surface, causing the fixed plate to vibrate and the lubricating powder material on the fixed plate to fall off. At the same time, several fixing holes on the surface of the fixed plate cause the lubricating powder material that has fallen on the fixed plate to move downwards, thus making it easier to remove the lubricating powder material from the fixed plate.

[0010] Specifically, the tank body is bolted to a bracket that supports the tank body, and the bracket is bolted to a cylinder that provides power. The power output end of the cylinder is screwed to a top cover that contacts the top of the tank body.

[0011] By adopting the above technical solution, when the lubricating powder raw material is to be put into the tank, the cylinder outside the support is driven by the external controller to move the top cover, and then the top cover separates from the tank, which makes it easier to put the lubricating powder raw material into the screen frame inside the tank.

[0012] Specifically, the bottom of the tank is bolted to a bottom tank for collecting the sieved lubricating powder, and the bottom of the bottom tank is threaded to a bottom cover for removing the sieved lubricating powder.

[0013] By adopting the above technical solution, when the screen at the bottom of the screen frame screens the lubricating powder raw material, the screened lubricating powder raw material falls into the bottom tank at the bottom of the tank body, and the bottom of the bottom tank is tilted inward. Then, the bottom cover of the bottom tank is rotated to separate the bottom cover from the bottom tank, so that the screened lubricating powder raw material can be easily taken out.

[0014] Specifically, the tank body is rotatably connected to pulleys A and B, which move the rope chain, with pulley A located on top of pulley B.

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

[0016] Specifically, a connecting block is welded to the outside of the screen frame, and a connecting groove is provided on the inside of the tank to allow the connecting block to slide.

[0017] By adopting the above technical solution, when the drive rod drives the screen frame to rotate, the connecting block welded to the outside of the screen frame slides in the connecting groove opened in the tank, thereby improving the stability of the screen frame rotation.

[0018] Specifically, the input terminals of both the cylinder and the servo motor are electrically connected to the power supply terminal of an external power source.

[0019] By adopting the above technical solution and connecting to an external power source, the electrical equipment can operate normally.

[0020] The beneficial effects of this utility model are:

[0021] (1) The raw material screening device for lubricating powder processing described in this utility model, when the screen at the bottom of the screen frame screens the lubricating powder raw material, the receiving plate outside the drive rod drives the rope chain to wind up, and then the rope chain drives the fixed plate to move. Both the receiving plate and the rope chain outside the drive rod are provided in two sets, so that the fixed plate moves upward. Then the support block on the fixed plate enters the screen, so that the lubricating powder raw material stuck in the screen is pushed out. Then the servo motor is driven by the external controller to drive the drive rod to rotate counterclockwise, so that the receiving plate outside the drive rod drives the rope chain to unwind. The rope chain drives the fixed plate to separate from the screen, thereby avoiding the screen for screening lubricating powder raw material from becoming blocked.

[0022] (2) The raw material screening device for lubricating powder processing described in this utility model, when the support block on the fixed plate enters the screen, the fixed plate contacts the screen surface, causing the vibration generated by the fixed plate to shake off the lubricating powder raw material on the fixed plate. At the same time, several fixing holes opened on the surface of the fixed plate cause 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] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] To prevent clogging of the screen 19 used for screening lubricating powder raw materials, as one embodiment of this utility model, such as Figure 1 , Figure 2 As shown, the present invention discloses a raw material screening device for lubricating powder processing, comprising a tank 2, wherein a servo motor 7 for providing power is bolted inside the tank 2, and a drive rod 15 is keyed to the power output end of the servo motor 7; a screen frame 17 for placing lubricating powder raw materials is welded to the end of the drive rod 15 away from the servo motor 7; a screen 19 for screening lubricating powder raw materials is screwed to the bottom of the screen frame 17; a collection tray 16 is sleeved on the outside of the drive rod 15, and a rope chain 9 is wound around the outside of the collection tray 16; a fixing plate 14 is screwed to the end of the rope chain 9 away from the collection tray 16; a support block 13 for entering the screen 19 is welded to the outside of the fixing plate 14; and a number of fixing holes 18 are provided on the surface of the fixing plate 14 to move the lubricating powder downward.

[0029] When the lubricating powder raw material is put into the screen frame 17 inside the tank 2, the servo motor 7 inside the tank 2 converts the received electrical energy into mechanical energy under the action of the external controller. The servo motor 7 drives the drive rod 15 to rotate clockwise, and then the drive rod 15 drives the screen frame 17 to rotate, so that the screen 19 at the bottom of the screen frame 17 screens the lubricating powder raw material.

[0030] When the screen 19 at the bottom of the screen frame 17 screens the lubricating powder raw material, the receiving plate 16 outside the drive rod 15 drives the rope chain 9 to wind up. Then the rope chain 9 drives the fixed plate 14 to move. Both the receiving plate 16 outside the drive rod 15 and the rope chain 9 are provided in two sets, so that the fixed plate 14 moves upward. Then the support block 13 on the fixed plate 14 enters the screen 19, so that the lubricating powder raw material stuck in the screen 19 is pushed out. Then the servo motor 7 drives the drive rod 15 to rotate counterclockwise under the action of the external controller, so that the receiving plate 16 outside the drive rod 15 drives the rope chain 9 to unwind. The rope chain 9 drives the fixed plate 14 to separate from the screen 19, thereby avoiding the screen 19 for screening lubricating powder raw material from becoming blocked.

[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, causing the fixed plate 14 to vibrate, causing the lubricating powder material on the fixed plate 14 to fall off. At the same time, the several fixing holes 18 opened on the surface of the fixed plate 14 cause the lubricating powder material that falls on the fixed plate 14 to move downward, thereby facilitating the removal of the lubricating powder material on the fixed plate 14.

[0032] To place the lubricating powder raw material into the sieve 17 inside the tank 2, for example, as shown... Figure 1 As shown, the present invention also includes a bracket 5 for supporting the tank body 2, which is bolted to the outside of the tank body 2, and a cylinder 3 for providing power is bolted to the outside of the bracket 5. The power output end of the cylinder 3 is screwed to a top cover 1 that contacts the top of the tank body 2.

[0033] When the lubricating powder is to be placed into the tank 2, the cylinder 3 outside the bracket 5 is driven by the external controller to move the top cover 1. Then the top cover 1 separates from the tank 2, which makes it easier to put the lubricating powder into the screen frame 17 inside the tank 2.

[0034] To remove the sieved lubricating powder raw material, for example, such as Figure 2 As shown, the present invention also includes a bottom tank 6 for collecting the sieved lubricating powder, which is bolted to the bottom of the tank body 2, and a bottom cover 4 for removing the sieved lubricating powder is threaded to the bottom of the bottom tank 6.

[0035] When in use, when the screen 19 at the bottom of the screen frame 17 screens the lubricating powder material, the screened lubricating powder 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. 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, so that the screened lubricating powder material can be easily taken out.

[0036] To improve the stability of the movement of the rope chain 9, for example, such as Figure 2 As shown, the present invention also includes a pulley A8 and a pulley B12 rotatably connected inside the tank body 2 to move the rope chain 9, and the pulley A8 is located on the upper side of the pulley B12.

[0037] When in use, as the rope chain 9 moves the fixed plate 14, the rope chain 9 slides within the pulleys A8 and B12 installed inside the tank body 2, improving the stability of the rope chain 9's movement.

[0038] To improve the stability of the rotation of the screen frame 17, for example, such as Figure 2 As shown, the present invention also includes a connecting block 10 welded to the outside of the screen frame 17, and a connecting groove 11 for sliding the connecting block 10 is provided on the inner side of the tank body 2.

[0039] When in use, when the drive rod 15 drives the screen frame 17 to rotate, the connecting block 10 welded to the outside of the screen frame 17 slides in the connecting groove 11 opened inside the tank body 2, which improves the stability of the rotation of the screen frame 17.

[0040] For electrical equipment to function properly, for example, such as Figure 1 , Figure 2 As shown, the present invention also includes that the input terminals of the cylinder 3 and the servo motor 7 are both electrically connected to the power supply terminal of an external power source.

[0041] When in use, the electrical equipment works normally by connecting to an external power source.

[0042] When this utility model is in use, when the lubricating powder raw material is put into the screen frame 17 inside the tank 2, the servo motor 7 inside the tank 2 converts the received electrical energy into mechanical energy under the action of the external controller. The servo motor 7 drives the drive rod 15 to rotate clockwise, and then the drive rod 15 drives the screen frame 17 to rotate, so that the screen 19 at the bottom of the screen frame 17 screens the lubricating powder raw material.

[0043] When the screen 19 at the bottom of the screen frame 17 screens the lubricating powder raw material, the receiving plate 16 outside the drive rod 15 drives the rope chain 9 to wind up. Then the rope chain 9 drives the fixed plate 14 to move. Both the receiving plate 16 outside the drive rod 15 and the rope chain 9 are provided in two sets, so that the fixed plate 14 moves upward. Then the support block 13 on the fixed plate 14 enters the screen 19, so that the lubricating powder raw material stuck in the screen 19 is pushed out. Then the servo motor 7 drives the drive rod 15 to rotate counterclockwise under the action of the external controller, so that the receiving plate 16 outside the drive rod 15 drives the rope chain 9 to unwind. The rope chain 9 drives the fixed plate 14 to separate from the screen 19, thereby avoiding the screen 19 for screening lubricating powder raw material from becoming blocked.

[0044] 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, causing the fixed plate 14 to vibrate, causing the lubricating powder material on the fixed plate 14 to fall off. At the same time, the several fixing holes 18 opened on the surface of the fixed plate 14 cause the lubricating powder material that falls on the fixed plate 14 to move downward, thereby making it easier to remove the lubricating powder material on the fixed plate 14.

[0045] When the lubricating powder raw material is to be put into the tank 2, the cylinder 3 outside the support 5 is driven by the external controller to move the top cover 1. Then the top cover 1 separates from the tank 2, so that the lubricating powder raw material can be put into the screen frame 17 inside the tank 2.

[0046] 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 tilts inward. 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, so that the screened lubricating powder raw material can be easily taken out.

[0047] When the rope chain 9 moves the fixed plate 14, the rope chain 9 slides in the pulleys A8 and B12 installed inside the tank body 2, which improves the stability of the movement of the rope chain 9.

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

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
