Description

Technical Field

[0001] This utility model relates to the field of graphite preparation technology, and in particular to a vibrating sieve machine for preparing graphite powder. Background Technology

[0002] Graphite powder is a powdery substance made from natural or artificial graphite through processes such as crushing, grinding, and sieving. It is a common form of graphite. The graphite powder preparation vibrating sieve is a key piece of equipment used in the graphite powder production process to classify, separate, and homogenize graphite powder by particle size. Its core function is to screen graphite powder of different particle sizes according to specifications through mechanical vibration or oscillation, while removing impurities to ensure that the particle size distribution of graphite powder meets the application requirements.

[0003] When screening graphite powder, the staff will first start the screening machine, and then slowly pour the graphite powder into the feed inlet of the screening machine in small amounts multiple times to avoid overloading the screen surface due to excessive material feeding at one time. The graphite powder is screened by the vibration of the machine itself.

[0004] The existing technology has the following drawbacks: In some existing equipment, graphite powder is screened manually, which requires operators to repeatedly carry and feed the material, resulting in high labor intensity. At the same time, the open feeding method causes graphite powder to overflow frequently, and the overflowing dust will affect the health of the workers. The device is not practical enough. Therefore, a graphite powder preparation vibrating screening machine is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a vibrating sieving machine for preparing graphite powder, which aims to improve the problem of long-term manual feeding and high labor intensity in the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a graphite powder preparation vibrating sieving machine, comprising a vibrating drum, a motor fixedly connected to the inner wall of the vibrating drum, a rotating rod fixedly connected to the output end of the motor, a slidably connected screening screen to the outer wall of the rotating rod, a long rod fixedly connected to the upper surface of the screening screen, a protrusion fixedly connected to the inner wall of the vibrating drum, a feed inlet fixedly connected to the top of the vibrating drum, a movable mechanism fixedly connected to the inner wall of the feed inlet, a triangular plate fixedly connected to the inner wall of the vibrating drum, a moving rod slidably connected through the inner wall of the triangular plate, and a vibration assembly provided on the inner wall of the vibrating drum; The movable mechanism includes an opening and closing plate, which is slidably connected to the inner wall of the feed inlet. The right side wall of the opening and closing plate is elastically connected to the feed inlet via a movable spring.

[0007] As a further description of the above technical solution: The vibration assembly includes a fixed plate, which is fixedly connected to the inner wall of the vibrating barrel. A striking plate is elastically connected to the inner wall of the left end of the fixed plate via a movable spring, and a pressing block is in contact with the inner wall of the striking plate.

[0008] As a further description of the above technical solution: The rotating rod passes through and is rotatably connected to the inner wall of the vibrating tank, and the rotating rod passes through and is rotatably connected to the inner wall of the fixed plate.

[0009] As a further description of the above technical solution: The top end of the moving rod contacts the lower surface of the opening and closing plate, and the upper surface of the screening screen contacts the bottom end of the moving rod.

[0010] As a further description of the above technical solution: The inner sidewall of the long rod is in contact with the outer wall of the protrusion, and the outer wall of the screening mesh is in contact with the inner wall of the vibrating barrel.

[0011] As a further description of the above technical solution: The movable rod passes through and is slidably connected to the inner wall of the fixed plate.

[0012] As a further description of the above technical solution: The striking plate is slidably connected to the inner wall of the fixed plate, and the side wall of the striking plate is in contact with the inner wall of the vibrating barrel.

[0013] As a further description of the above technical solution: The compression block is fixedly connected to the outer wall of the moving rod.

[0014] This utility model has the following beneficial effects: 1.

[0015] 2. In this utility model, by setting a fixed plate, a striking plate, a movable spring and a squeezing block, the squeezing block squeezes the striking plate, causing the striking plate to strike the vibrating barrel, which in turn causes the vibrating barrel to vibrate and dislodge the graphite powder, thus preventing the graphite powder from adhering to the barrel wall, reducing the tedious steps of manually cleaning the barrel wall and further improving work efficiency.

[0018] 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.

[0019] Reference Figures 1-3This utility model provides an embodiment of a graphite powder preparation vibrating sieving machine, comprising a vibrating drum 1, a motor 3 fixedly connected to the inner wall of the vibrating drum 1, the motor 3 being an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction, a rotating rod 4 fixedly connected to the output end of the motor 3, a rectangular block being provided on the rotating rod 4 so that the sieving screen 5 can rotate with the rotating rod 4 while moving up and down, the sieving screen 5 being slidably connected to the outer wall of the rotating rod 4, a long rod 6 fixedly connected to the upper surface of the sieving screen 5, the long rod 6 being L-shaped, a protrusion 7 fixedly connected to the inner wall of the vibrating drum 1, a feed inlet 2 fixedly connected to the top of the vibrating drum 1, a movable mechanism fixedly connected to the inner wall of the feed inlet 2, and a triangular plate 11 fixedly connected to the inner wall of the vibrating drum 1. Plate 11 is triangular in shape, which allows the falling graphite powder to spread to both sides, preventing the graphite powder from falling onto the fixed plate 12. The inner wall of the triangular plate 11 is slidably connected to a moving rod 10. The triangular plate 11 has a slot corresponding to the moving rod 10, so that the moving rod 10 can move vertically. The inner wall of the vibrating tank 1 is provided with a vibration component. The movable mechanism includes an opening and closing plate 8, which is slidably connected to the inner wall of the feed inlet 2. The feed inlet 2 has a slot corresponding to the opening and closing plate 8, so that the opening and closing plate 8 can move left and right. The right side wall of the opening and closing plate 8 is elastically connected to the feed inlet 2 through a movable spring 9. When the two sets of opening and closing plates 8 are separated, the movable spring 9 is compressed. When resetting, the elastic force of the movable spring 9 brings the two sets of opening and closing plates 8 closer together.

[0020] Reference Figure 1 , Figure 5 and Figure 6 The vibration assembly includes a fixed plate 12, which is fixedly connected to the inner wall of the vibrating barrel 1. The left end of the fixed plate 12 is elastically connected to a striking plate 13 via a moving spring 14. When the striking plate 13 moves to the left, the moving spring 14 is compressed. When resetting, the striking plate 13 is reset by the elastic force of the moving spring 14. The inner wall of the striking plate 13 contacts a pressing block 15. The striking plate 13 has an inclined surface inside. When the pressing block 15 presses the inclined surface, the striking plate 13 moves to the left. The striking plate 13 is slidably connected to the inner wall of the fixed plate 12. The fixed plate 12 has a slot corresponding to the striking plate 13, allowing the striking plate 13 to move left and right. The side wall of the striking plate 13 contacts the inner wall of the vibrating barrel 1. When the striking plate 13 strikes the vibrating barrel 1, it causes the vibrating barrel 1 to vibrate, causing graphite powder to fall off the barrel wall. The pressing block 15 is fixedly connected to the outer wall of the moving rod 10.

[0021] Reference Figures 2-4The rotating rod 4 is rotatably connected to the inner wall of the vibrating tank 1. Both the vibrating tank 1 and the fixed plate 12 have slots corresponding to the rotating rod 4 to facilitate the rotation of the rotating rod 4. The top of the moving rod 10 contacts the lower surface of the opening and closing plate 8. The moving rod 10 will squeeze the opening and closing plate 8, causing the two sets of opening and closing plates 8 to separate from each other. The upper surface of the screening screen 5 contacts the bottom end of the moving rod 10. The screening screen 5 will squeeze the moving rod 10, causing the moving rod 10 to move upward. The inner side wall of the long rod 6 contacts the outer wall of the protrusion 7. The protrusion 7 will squeeze the long rod 6, causing the long rod 6 to move upward. The outer wall of the screening screen 5 contacts the inner wall of the vibrating tank 1. The moving rod 10 is slidably connected to the inner wall of the fixed plate 12. The fixed plate 12 has slots corresponding to the moving rod 10, allowing the moving rod 10 to move vertically.

[0022] Working principle: When graphite powder needs to be sieved, the operator can turn on motor 3. Motor 3 will rotate rotating rod 4 and sieve screen 5. When the long rod 6 on sieve screen 5 contacts the protrusion 7, the protrusion 7 will squeeze the long rod 6, causing sieve screen 5 to move upward. Sieve screen 5 will squeeze moving rod 10 upward. When moving rod 10 squeezes opening and closing plate 8, the two sets of opening and closing plates 8 will separate and squeeze movable spring 9. At this time, graphite powder will fall into vibrating tank 1 from the gap between the two sets of opening and closing plates 8. At the same time, moving rod 10 will move squeezing block 15 upward. When squeezing block 15 squeezes the inclined surface on striking plate 13, striking plate 13 will move to the left and squeeze moving spring 14. As sieve screen 5 rotates, when long rod 6 is no longer in contact with protrusion 7, the graphite powder will fall into the vibrating tank 1. Under its own gravity, the screening screen 5 moves downward along with the long rod 6. As the screening screen 5 moves up and down, it screens the graphite powder. At the same time, the moving rod 10 also moves downward under its own gravity. When the moving rod 10 is no longer in contact with the opening and closing plate 8, the two sets of opening and closing plates 8 move closer together and close under the elastic force of the movable spring 9. At the same time, the squeezing block 15 no longer contacts the inclined surface on the striking plate 13. Under the elastic force of the moving spring 14, the striking plate 13 moves to the right. When the striking plate 13 strikes the vibrating barrel 1, it causes the vibrating barrel 1 to vibrate, preventing the graphite powder from adhering to the barrel wall. When the long rod 6 contacts the protrusion 7 again, the screening screen 5 continues to repeat the above trajectory movement. If it is necessary to screen the graphite powder again, simply repeat the above operation steps.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
