[0044] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0045] Example 1:

[0046] like Figures 1-2 and Figure 5 As shown, one embodiment of the present invention provides a flexible screen cleaning device, including a drive mechanism and a vibration mechanism 9;

[0047] The vibration mechanism 9 is connected to the drive mechanism, which drives the vibration mechanism 9 to reciprocate to change the amplitude of the flexible screen surface.

[0048] The drive mechanism drives the vibration mechanism 9 to move back and forth, thereby changing the amplitude of the flexible screen surface. This allows the wet and sticky material that is blocked in the screen holes of the flexible screen to be vibrated out. The wet and sticky material on the screen surface is also shaken off due to the different amplitudes, improving the screening effect and efficiency. There is no need for manual cleaning of the flexible screen regularly, saving time and effort.

[0049] According to one embodiment of the present invention, the driving mechanism includes a driving component 1, a connecting plate 3, and a transmission component;

[0050] The transmission assembly includes an eccentric shaft 2;

[0051] One side of the connecting plate 3 abuts against the circumferential surface of the eccentric shaft 2, and the other side is connected to the vibration mechanism 9;

[0052] The output end of the drive component 1 is connected to the eccentric shaft 2, which drives the eccentric shaft 2 to rotate eccentrically, thereby causing the connecting plate 3 to move back and forth alternately along the direction away from the flexible screen and towards the flexible screen, so that the vibration mechanism 9 intermittently abuts against the flexible screen.

[0053] According to one embodiment of the present invention, the transmission assembly further includes an elastic reset member 4 and a guide member 5;

[0054] Connecting plate 3 is slidably connected to guide member 5;

[0055] One end of the elastic reset member 4 is fixed, and the other end is connected to the side of the connecting plate 3 away from the eccentric shaft 2;

[0056] The elastic reset member 4 is initially in a pre-compressed state, applying elastic force to the connecting plate 3 on the side facing the eccentric shaft 2.

[0057] Of course, in this embodiment, the elastic reset member 4 can also be located in other positions. In this case, one end of the elastic reset member 4 is fixed, and the other end is connected to the side of the connecting plate 3 near the eccentric shaft 2. The elastic reset member 4 is initially in a pre-stretched state, applying an elastic force to the connecting plate 3 towards the eccentric shaft 2. This also ensures that the connecting plate 3 always abuts against the eccentric shaft 2. Its purpose does not depart from the design concept of this utility model, therefore, it should fall within the protection scope of this utility model.

[0058] According to one embodiment of the present invention, such as Figure 2 As shown, the guide member 5 is a sliding rod, and the elastic reset member 4 includes a spring 401 and a limiting ring 402;

[0059] Spring 401 is sleeved on the sliding rod, one end of spring 401 is connected to the limiting ring 402, and the other end abuts against the connecting plate 3;

[0060] The limiting ring 402 is fixedly connected to the sliding rod;

[0061] The length of the sliding rod is perpendicular to the screen surface of the flexible screen.

[0062] When the eccentric shaft 2 rotates, the spring 401 always provides the connecting plate 3 with a spring force towards the eccentric shaft 2, so that the connecting plate 3 can always abut against the eccentric shaft 2. Since the connecting plate 3 is slidably connected to the sliding rod, when the eccentric shaft 2 rotates, the connecting plate 3 moves back and forth along the length of the sliding rod, thereby driving the vibration mechanism 9 installed on the connecting plate 3 to move back and forth intermittently to abut against the flexible screen, so that the screen surface of the flexible screen has different amplitudes, so that the screen surface of the flexible screen can generate additional vibration force in addition to the vibration force of the vibration motor of the vibrating screen itself, thereby knocking off the wet and sticky materials on the screen surface of the flexible screen and the wet and sticky materials in the screen holes, cleaning the screen surface and screen holes of the flexible screen, improving working efficiency and screening effect.

[0063] The length direction of spring 401 is the same as the length direction of sliding rod, and the axis of eccentric shaft 2 is parallel to the screen surface of flexible screen.

[0064] The spring 401 serves as a buffer and reset mechanism, while also reducing the noise generated when the flexible screen vibrates.

[0065] Furthermore, one end of the spring 401 abuts against the limiting ring 402, and the other end abuts against the connecting plate 3. The limiting ring 402 includes two symmetrically arranged arc plates. An annular groove is provided on the sliding rod. Both arc plates are located in the annular groove. The two arc plates are fixedly connected by bolts, thereby fixing the limiting ring 402 and the sliding rod. At this time, it is convenient to disassemble and replace the spring 401.

[0066] Furthermore, two sliding rods can be symmetrically arranged, resulting in greater stability when the connecting plate 3 moves.

[0067] Spring 401 is sleeved on sliding rod, and sliding rod can limit spring 401 so that spring 401 can only extend and retract along its length.

[0068] Furthermore, the transmission assembly also includes a first limiting tube and a second limiting tube. The first limiting tube is sleeved on the second limiting tube and slidably connected to the second limiting tube. The spring 401 is disposed inside the second limiting tube. One end of the spring 401 is connected to the first limiting tube, and the other end of the spring 401 is connected to the second limiting tube. The second limiting tube is fixedly connected to the connecting plate 3, and the first limiting tube is fixedly connected to the sliding rod, which can limit the spring 401 so that it only extends or shortens along its length direction.

[0069] Optionally, both ends of the spring 401 can also be connected to the limiting ring 402 and the connecting plate 3 respectively. This does not depart from the design concept of this utility model, and therefore should fall within the protection scope of this utility model.

[0070] According to one embodiment of the present invention, such as Figure 1 As shown, the drive assembly 1 includes a drive motor 101, a first transmission belt 103 and a drive pulley 102, and the transmission assembly also includes a mounting plate 10, a driven pulley 6 and a bearing seat 7.

[0071] The output end of the drive motor 101 is connected to the drive pulley 102. The drive pulley 102 and the driven pulley 6 are connected by the first transmission belt 103. The bearing housing 7 is rotatably connected to the first connecting shaft. One end of the first connecting shaft is connected to the driven pulley 6, and the other end is connected to the eccentric shaft 2.

[0072] The bearing housing 7 is fixedly connected to the mounting plate 10;

[0073] like Figure 4 As shown, the mounting plate 10 is used to connect with the mounting frame for mounting the flexible screen.

[0074] The sliding rod is fixedly connected to the mounting plate 10.

[0075] The eccentric shaft 2 includes a circular plate and a bearing. A first through hole is provided on the circular plate. One end of the first connecting shaft is connected to the first through hole. The axis of the first through hole does not coincide with the axis of the circular plate. The bearing is connected to the side wall of the circular plate. The inner side wall of the bearing inner ring and the side wall of the circular plate are interference-fitted. The connecting plate 3 abuts against the outer side wall of the bearing outer ring, thereby reducing the friction between the connecting plate 3 and the eccentric shaft 2 and improving the stability during operation.

[0076] According to one embodiment of the present invention, a set of transmission components is provided on both sides of the connecting plate 3 along the width direction of the flexible screen surface.

[0077] The two eccentric shafts 2 in the two sets of transmission components are connected by a second connecting shaft.

[0078] By setting a set of transmission components on both sides of the connecting plate 3, the connecting plate 3 can move back and forth more smoothly and stably.

[0079] According to one embodiment of the present invention, the driving mechanism includes a plurality of connecting plates 3, and the plurality of connecting plates 3 correspond one-to-one with the vibration mechanism 9;

[0080] Multiple connecting plates 3 are arranged at intervals along the length of the flexible screen surface;

[0081] The drive mechanism also includes a second transmission belt 8, and the driven pulley 6 is a double-grooved pulley;

[0082] Along the length of the flexible screen surface, each pair of adjacent double-groove pulleys are connected by a second transmission belt 8.

[0083] The second transmission belt 8 can drive each pair of adjacent double-groove pulleys along the length of the flexible screen to rotate around their respective axes, causing the eccentric shaft 2 corresponding to the double-groove pulleys to rotate. The spring 401 and the eccentric shaft 2 work together to make each corresponding connecting plate 3 reciprocate along the length of the sliding rod.

[0084] By using multiple connecting plates 3, multiple locations on the flexible screen surface can be vibrated and struck, enabling better cleaning of the flexible screen.

[0085] When multiple connecting plates 3 are provided, the driven pulley 6 adopts a double groove pulley because it allows each of the two adjacent second transmission belts 8 to be located in the two annular grooves of the double groove pulley, so that they do not contact each other and the running stability is better.

[0086] Of course, in this embodiment, a drive motor 101 can be provided on one side of each connecting plate 3 to drive an eccentric shaft 2 corresponding to the bottom of each connecting plate 3 to rotate. In this case, the rotation speed of the drive motor 101 can be different, thereby making the frequency of the reciprocating movement of the connecting plate 3 along the sliding rod different, and the contact and impact time between the vibration mechanism 9 and the flexible screen different, so that the amplitude of the screen surface of the flexible screen is different at different positions, thereby achieving a better cleaning effect. Its purpose has not departed from the design concept of this utility model, therefore, it should fall within the protection scope of this utility model.

[0087] According to one embodiment of the present invention, such as Figure 6 As shown, the vibration mechanism 9 includes a striking plate 901, which is connected to the connecting plate 3. The striking plate 901 is used to strike the flexible screen.

[0088] The striking plate 901 is located on the underside of the flexible screen.

[0089] The striking plate 901 includes a main board and striking blades. The striking blades are located between the flexible screen and the main board. The main board is connected to the connecting plate 3. The striking blades are made of alloy steel, which has high hardness. The contact surface between the striking blades and the flexible screen is a blunt surface, so the flexible screen will not be damaged even if it collides with the flexible screen continuously.

[0090] The flexible screen has an acute angle between its surface and the horizontal plane. The length of the connecting plate 3 is the same as the width of the flexible screen.

[0091] According to one embodiment of the present invention, the striking plate 901 is provided with a plurality of weight reduction holes 902.

[0092] By setting multiple weight-reducing holes 902, the weight of the impact plate 901 can be reduced, consumables can be reduced, and costs can be saved.

[0093] Specifically, the drive motor 101 rotates, causing the active pulley 102, which is fixedly connected to its output end, to rotate. This drives the driven pulley 6, which is connected to the first transmission belt 103, to rotate. The driven pulley 6 is driven to rotate by multiple second transmission belts 8. In turn, each driven pulley 6 can drive its corresponding eccentric shaft 2 to rotate. As the eccentric shaft 2 rotates, the connecting plate 3 can reciprocate along the length of the sliding rod under the action of the spring 401 and the eccentric shaft 2. This causes the striking plate 901 connected to the connecting plate 3 to vibrate and strike the flexible screen, making the screen surface clean and the screen holes less prone to clogging. This improves the screening efficiency and screening effect, replacing manual cleaning and saving time and effort.

[0094] Example 2:

[0095] like Figures 3-5As shown, a vibrating screen includes a flexible screen cleaning device, and also includes a flexible screen, a mounting frame, a buffer mechanism, a vibrating motor, and a base;

[0096] The top of the mounting frame is connected to a flexible screen, and the bottom of the flexible screen is equipped with a flexible screen cleaning device.

[0097] The vibrating motor is mounted on the mounting frame and is used to drive the flexible screen to vibrate;

[0098] The mounting bracket and the base are connected by multiple sets of buffer mechanisms.

[0099] The base is placed on the ground, and the length of the mounting frame forms an acute angle with the horizontal plane. The mounting frame includes a first frame and a second frame. The first frame is fixedly connected to the top of the second frame by multiple support plates. A flexible screen is connected to the first frame, and a mounting plate 10 is connected to the second frame. The fixed end of the drive motor 101 is connected to the bottom of the second frame. The second frame is connected to the base by multiple sets of buffer mechanisms.

[0100] Because the first mounting bracket includes multiple reinforcing bars, such as Figure 3 and Figure 6 As shown, the length direction of the reinforcing rod is the same as the length direction of the flexible screen. Therefore, multiple clearance grooves 903 are provided on the striking plate 901 so that the reinforcing rod will not interfere with the striking plate 901 striking the flexible screen.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0102] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "connection" should be interpreted broadly.
