Description

Technical Field

[0001] This invention relates to the field of coating production technology, specifically to a novel crushing and filtering device for coating production. Background Technology

[0002] Paint, traditionally known as varnish in China, is a viscous liquid applied to the surface of an object to be protected or decorated, forming a firmly adhering, continuous film. It is typically composed of resins, oils, or emulsions, with or without pigments and fillers, and may contain appropriate additives, and is formulated with organic solvents or water.

[0003] Patent publication number CN215234662U relates to a novel crushing and filtering device for paint production, including a support leg. A filter box is fixedly connected to the top of the support leg. The filter box has a liquid outlet on its front and a mounting groove on its front. A first filter screen is movably connected to the inner wall of the mounting groove, and a second filter screen is movably connected to the inner wall of the mounting groove. The patent utilizes a crushing box, a feed pipe, a motor mechanism, a fixing cover, a heat dissipation vent, a heat dissipation mesh, a fixing rod, a first motor, a first rotating shaft, a first bearing, a short crushing rod, a connecting rod, and a second electric motor. The coordinated use of the machine, the second rotating shaft, the second bearing, and the long crushing rod achieves the desired crushing effect in this new type of coating production crushing and filtering device. This solves the problem of poor crushing effect in general new coating production crushing and filtering devices. During the production of new coatings, auxiliary materials need to be crushed and filtered. Good crushing effect allows for finer coatings that meet production needs, and also facilitates filtration and mixing. It prevents excessive particle contamination due to poor crushing, thus avoiding waste of raw materials and substandard production, and meets production requirements.

[0004] In the aforementioned patent, when the raw materials are added to the filter box through the feed pipe, if too much raw material is added, it may cause the raw materials to accumulate at the crushing roller, which may cause the feed pipe to become blocked, affecting the subsequent crushing operation. Furthermore, it may cause the coating raw materials to be crushed incompletely, affecting product quality and potentially causing damage to the equipment. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a novel crushing and filtering device for paint production, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a novel crushing and filtering device for paint production, comprising a filter box, a feed hood fixed to the top of the filter box, a drive motor fixed to the left side of the feed hood, a rotating rod fixed to the output end of the drive motor, the rotating rod penetrating the right side of the feed hood, and a crushing roller fixed to the outer wall of the rotating rod. Two sets of drive motors, rotating rods, and crushing rollers are arranged symmetrically about the vertical centerline of the filter box. When the two sets of drive motors are started, the rotating rod drives the two sets of crushing rollers to rotate downwards relative to each other for crushing operations. A discharge pipe is fixed to the bottom of the filter box, and a filter plate is hinged to the inner wall of the filter box, penetrating the right side of the filter box. An intermittent feeding control component is provided on the feed hood, and a discharge component is provided on the filter box to facilitate filtration by the filter plate. The control component includes a rotating block, a cylindrical block, a moving frame, an L-shaped connecting rod, a baffle plate, a transmission plate, and an arc-shaped block. The system includes a transmission rod, a connecting block, a hinge rod, a striking rod, and a return spring. The rotating block is fixed to the end point of the rotating rod. A cylindrical block is fixed to the side of the rotating block away from the rotating rod. A baffle plate extends through the side wall of the feed hood, and two sets of baffle plates are symmetrically arranged about the vertical centerline of the feed hood. A transmission plate is slidably installed on the inner wall of the side wall groove of the feed hood. Multiple sets of linearly arrayed arc-shaped blocks are fixed to the bottom of the transmission plate. An L-shaped connecting rod is fixed to the side wall of the baffle plate. A movable frame is fixed at the end of the connecting rod away from the baffle plate. The inner wall of the movable frame is in contact with the outer wall of the cylindrical block. When the rotating rod rotates, it can drive the rotating block and the cylindrical block to rotate. When the two sets of rotating blocks drive the two sets of cylindrical blocks away from each other, the cylindrical blocks press the two sets of movable frames away from each other. The L-shaped connecting rod can drive the two sets of baffle plates to move out of the feed hood. When the rotating rod drives the two sets of rotating blocks and cylindrical blocks to move closer to each other, it can drive the two sets of movable frames to move closer to each other. Thus, the L-shaped connecting rod can drive the two sets of baffle plates to move closer to each other.

[0007] According to the above technical solution, a return spring is fixed at the bottom of the transmission plate, and the bottom of the return spring is fixed to the inner wall of the slide groove on the side wall of the feed hood.

[0008] According to the above technical solution, a transmission rod passes through the feed hood, and the transmission rod is slidably connected to the feed hood at the through-hole. A striking rod is fixed to the outer wall of the transmission rod, and a connecting block is fixed to the end of the transmission rod. A hinge rod is hinged to the bottom of the connecting block. The end of the hinge rod away from the connecting block is hinged to the top of the transmission plate. When the two sets of moving frames move, the moving frames will press the arc-shaped block at the bottom of the transmission plate. When the arc-shaped block is subjected to the pressing force, the transmission plate will move upward, thereby causing the transmission plate to press the hinge rod, which can cause the hinge rod to press the connecting block and move towards the feed hood, thereby causing the transmission rod to drive the striking rod to move.

[0009] According to the above technical solution, the feeding assembly includes an L-shaped connecting rod, a long plate, a dispersing rod, an auxiliary rod, a connecting seat, a striking ball, a connecting spring, an inclined block, a movable rod, and a triangular block. The L-shaped connecting rod is fixed to the bottom of the moving frame and extends through the top of the filter box. A long plate is fixed to the end of the L-shaped connecting rod away from the moving frame. Multiple sets of dispersing rods arranged in a linear array are fixed to the bottom of the long plate. When the moving frame moves back and forth, it will cause the moving frame to move the L-shaped connecting rod, which in turn will cause the L-shaped connecting rod to move the long plate, and the long plate will cause the dispersing rods to move on the filter plate.

[0010] According to the above technical solution, an auxiliary rod runs through the long board, a connecting seat is fixed at the bottom of the auxiliary rod, a striking ball is provided on the inner side of the bottom of the connecting seat, a connecting spring is fixed at the top of the connecting seat, the top of the connecting spring is fixed to the bottom of the long board, an inclined block is slidably installed on the top of the long board, a movable rod is hinged to the outer wall of the auxiliary rod, and the end of the movable rod away from the auxiliary rod is hinged to the top of the inclined block.

[0011] According to the above technical solution, the inner wall of the filter box is fixed with multiple sets of triangular blocks arranged in a linear array. When the long plate moves, it can drive the inclined block to move. When the inclined block moves on the triangular block, it will be subjected to a squeezing force, causing the inclined block to move towards the auxiliary rod. This will cause the inclined squeezing movable rod to rotate at the hinge, thereby squeezing the auxiliary rod to move upward, causing the connecting seat to drive the striking ball to move upward.

[0012] According to the above technical solution, the discharge assembly includes a connecting column, a push plate, a diagonal rod, a push rod, a transmission spring, a limiting rod, a limiting hole, a disc, a return spring, a spring sheet, and a transmission block. The connecting column penetrates the side wall of the long plate. One end of the connecting column is fixed with a push plate, and the other end of the connecting column is hinged with a diagonal rod. The end of the long plate is penetrated by a push rod, and a diagonal rod is hinged to the push rod. The end of the diagonal rod away from the push rod is hinged to the connecting column. When the push plate is subjected to extrusion force, it will move the push plate closer to the long plate, causing the connecting column to move inward into the long plate. This causes the connecting column to squeeze the diagonal rod at the hinge point and rotate, thereby causing the diagonal rod to squeeze the push rod outward from the long plate.

[0013] According to the above technical solution, a limiting rod passes through the side wall of the filter box, and a limiting hole is opened on the side wall of the filter plate. The outer wall of the limiting rod fits against the inner wall of the limiting hole. A spring plate is fixed to the bottom of the filter plate, and the side of the spring plate away from the filter plate is fixed to the inner wall of the filter box. A disc is fixed to the outer wall of the limiting rod, and a return spring is fixed to the side wall of the disc. The side of the return spring away from the disc is fixed to the side wall of the filter box. A transmission block is fixed to the end of the limiting rod. When the push rod moves outward from the long plate, it will cause the push rod to squeeze the transmission block, causing the transmission block to drive the limiting rod to move out of the limiting hole, thereby releasing the limiting of the filter plate. Through the cooperation of the spring plate, the spring plate causes the filter plate to tilt.

[0014] This invention provides a novel crushing and filtering device for paint production. It has the following beneficial effects:

[0015] (1) In order to facilitate the crushing operation, when the rotating rod rotates, the rotating block can drive the cylindrical block to move in the middle of the moving frame. Thus, through the L-shaped connecting rod, the two sets of baffles can move back and forth to open and close the feed hood, enabling intermittent feeding, which facilitates the crushing operation and prevents too much raw material from being added into the feed hood, causing the feed hood to become blocked. When the moving frame moves, the top of the moving frame will press the arc-shaped block. With the cooperation of the return spring, the transmission plate can move up and down. With the cooperation of the hinge rod, the transmission rod can drive the striking rod to move left and right in the feed hood, which facilitates the breaking up of the paint raw materials that are stuck together and the crushing operation of the crushing roller.

[0016] (2) When the moving frame moves back and forth, it can drive the L-shaped connecting rod to move back and forth, thereby enabling the long plate to drive the dispersing rod to move back and forth on the filter plate, which can disperse the crushed raw materials that have fallen to one position, making it convenient for the filter plate to perform screening operations. When the long plate moves back and forth, the inclined block moves back and forth on the triangular block. Through the cooperation of the movable rod, auxiliary rod, connecting seat and striking ball, the striking ball can strike the filter plate back and forth, improving the screening efficiency and preventing the filter plate from clogging.

[0017] (3) When the long plate moves back and forth, when the raw material piled on the filter plate is too high and exceeds the push plate, the push plate will be subjected to squeezing pressure when it moves. Through the cooperation of the connecting column and the inclined rod, the push rod will squeeze the transmission block, so that the transmission block can drive the limit rod to move out of the limit hole, thereby releasing the limit on the filter plate. Because the spring plate is in a stretched state, the spring plate will drive the filter plate to rotate downward, causing the filter plate to tilt and discharge the raw material on the filter plate from the opening on the right side of the filter box, preventing the raw material piled up in the equipment from causing blockage and damage to the machine.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1-5One embodiment of the present invention is: a novel crushing and filtering device for paint production, comprising a filter box 1, a feed hood 2 fixed to the top of the filter box 1, a drive motor 4 fixed to the left side of the feed hood 2, a rotating rod 5 fixed to the output end of the drive motor 4, the rotating rod 5 passing through the right side of the feed hood 2, and a crushing roller 6 fixed to the outer wall of the rotating rod 5. Two sets of drive motor 4, rotating rod 5, and crushing roller 6 are provided, and the two sets of drive motor 4, rotating rod 5, and crushing roller 6 are symmetrically arranged about the center line in the vertical direction of the filter box 1 as an axis of symmetry. A discharge pipe 3 is fixed at the bottom, and a filter plate 7 is hinged to the inner wall of the filter box 1. The filter plate 7 passes through the right side of the filter box 1. An intermittent feeding control component is provided on the feed hood 2, and a feeding component is provided on the filter box 1 to facilitate filtration by the filter plate 7. It also includes a discharge component. The control component includes a rotating block 8, a cylindrical block 9, a moving frame 10, an L-shaped connecting rod 11, a baffle plate 12, a transmission plate 13, an arc-shaped block 14, a transmission rod 15, a connecting block 16, a hinge rod 17, a striking rod 18, and a return spring 21. The rotating block 8 is fixed to the rotating... At the end of rod 5, a cylindrical block 9 is fixed to the side of rotating block 8 away from rotating rod 5. A baffle plate 12 passes through the side wall of feed hood 2, and is slidably connected at the penetration point. Two sets of baffle plates 12 are provided, and the two sets of baffle plates 12 are symmetrically arranged about the center line in the vertical direction of feed hood 2. A transmission plate 13 is slidably installed on the inner wall of the side wall groove of feed hood 2. Multiple sets of arc-shaped blocks 14 arranged in a linear array are fixed to the bottom of transmission plate 13. An L-shaped connecting rod 11 is fixed to the side wall of baffle plate 12, and an L-shaped connecting rod 11 is fixed to the end away from baffle plate 12. The inner wall of the movable frame 10 is in contact with the outer wall of the cylindrical block 9. A return spring 21 is fixed at the bottom of the transmission plate 13. The bottom of the return spring 21 is fixed to the inner wall of the slide groove on the side wall of the feed hood 2. A transmission rod 15 passes through the feed hood 2 and is slidably connected to the through point of the feed hood 2. A striking rod 18 is fixed to the outer wall of the transmission rod 15. A connecting block 16 is fixed to the end of the transmission rod 15. A hinge rod 17 is hinged to the bottom of the connecting block 16. The end of the hinge rod 17 away from the connecting block 16 is hinged to the top of the transmission plate 13.

[0030] By moving the baffle plate 12 back and forth in the feed hood 2, the crushing roller 6 can be fed intermittently, preventing too much raw material from being added into the feed hood 2 at one time, which would cause blockage at the feed hood 2, affect work efficiency, and result in incomplete crushing of the coating raw material.

[0031] By setting multiple sets of striking rods 18 inside the feed hood 2, when the paint raw material is added into the feed hood 2, the striking rods 18 will strike the inside of the feed hood 2 back and forth, which can break up the paint raw material that is stuck together, making it easier for subsequent crushing operations and preventing the paint raw material from sticking together in lumps due to moisture, which would make subsequent crushing operations inconvenient.

[0032] In this embodiment, during operation: when paint production is required, two sets of drive motors 4 are started, causing the rotating rod 5 to drive two sets of crushing rollers 6 to rotate downwards relative to each other. Paint raw materials are then added into the equipment through the feed hood 2. The crushing is performed by the rotation of the two sets of crushing rollers 6. After crushing, the raw materials fall onto the filter plate 7, which filters the crushed materials. Furthermore, the rotation of the rotating rod 5 drives the rotating block 8 to rotate, causing the rotating block 8 to drive the cylindrical block 9 in a circular motion. When the two sets of cylindrical blocks 9 rotate away from each other, the cylindrical blocks 9 press against the inner side of the moving frame 10. The rotating block 8 presses the two sets of moving frames 10 away from each other, causing the moving frames 10 to move the L-shaped connecting rod 11. This causes the L-shaped connecting rod 11 to move the baffle plate 12 out of the feed hood 2. When the rotating block 8 drives the cylindrical block 9 to rotate closer together, the cylindrical block 9 will cause the two sets of moving frames 10 to move closer together, causing the L-shaped connecting rod 11 to move the two sets of baffle plates 12 into the feed hood 2. Thus, when the two sets of moving frames 10 move back and forth, the L-shaped connecting rod 11 causes the baffle plate 12 to move back and forth within the feed hood 2, opening and closing the baffle plate 12, thereby enabling intermittent feeding. When the two sets of moving frames 10 move back and forth, the top of the moving frame 10 will press against the bottom arc surface of the arc block 14, causing the arc block 14 to move upward under pressure. This causes the transmission plate 13 to move upward, stretching the return spring 21. When the transmission plate 13 moves upward, it will press against the hinge rod 17, causing the hinge rod 17 to rotate at the hinge point. This causes the hinge rod 17 to press the connecting block 16 away from the feed hood 2, thereby causing the connecting block 16 to drive the transmission rod 15 to move within the feed hood 2, and causing the striking rod 18 to move within the feed hood 2. When the moving frame 10 moves to a position where it is not in contact with the feed hood 2... When the arc-shaped block 14 makes contact, the return spring 21 is in a stretched state, which causes the return spring 21 to drive the transmission plate 13 to move. The transmission plate 13 pulls the hinge rod 17, which in turn pulls the connecting block 16 towards the feed hood 2. This causes the transmission rod 15 to drive the striking rod 18 to reset. The striking rod 18 moves back and forth inside the feed hood 2, which causes the striking rod 18 to break up the paint raw materials that are stuck together in blocks. This facilitates the subsequent crushing operation, prevents the raw materials from sticking together, and prevents uneven material distribution, which would affect the crushing efficiency and result in uneven particle size of the crushed material.

[0033] Please see Figures 1-9Based on the above embodiments, in another embodiment of the present invention, the feeding assembly includes an L-shaped connecting rod 1901, a long plate 1902, a dispersing rod 1903, an auxiliary rod 1904, a connecting seat 1905, a striking ball 1906, a connecting spring 1907, an inclined block 1908, a movable rod 1910, and a triangular block 1909; the L-shaped connecting rod 1901 is fixed to the bottom of the movable frame 10, and the L-shaped connecting rod 1901 passes through the top of the filter box 1, and the L-shaped connecting rod 1901 can move left and right at the point through which it passes in the filter box 1; the end of the L-shaped connecting rod 1901 away from the movable frame 10 is fixed with a long plate 1902, and the bottom of the long plate 1902 is fixed with multiple sets of linear arrays. The filter box 1 has a dispersing rod 1903, an auxiliary rod 1904 passing through the long plate 1902 and slidingly connected at the point of penetration, a connecting seat 1905 fixed at the bottom of the auxiliary rod 1904, a striking ball 1906 provided on the inner side of the bottom of the connecting seat 1905, a connecting spring 1907 fixed at the top of the connecting seat 1905, the top of the connecting spring 1907 fixed at the bottom of the long plate 1902, a ramp block 1908 slidably installed at the top of the long plate 1902, a movable rod 1910 hinged to the outer wall of the auxiliary rod 1904, the end of the movable rod 1910 away from the auxiliary rod 1904 hinged to the top of the ramp block 1908, and multiple sets of triangular blocks 1909 arranged in a linear array fixed to the inner wall of the filter box 1.

[0034] By setting the dispersing rod 1903 to move back and forth on the filter plate 7, the dispersing rod 1903 can disperse the raw materials piled up on the top of the filter plate 7, which facilitates the screening operation of the filter plate 7 and prevents the raw materials from piling up and making subsequent screening operations inconvenient.

[0035] By setting the striking ball 1906, when the long plate 1902 moves in the filter box 1, the striking ball 1906 can strike the top of the filter plate 7 back and forth, which can improve the screening efficiency of the filter plate 7. Furthermore, the striking ball 1906 is rolled on the bottom of the connecting seat 1905, thereby reducing the friction when the striking ball 1906 moves on the filter plate 7, making it easier to move smoothly.

[0036] The material discharge assembly includes a connecting column 2001, a push plate 2002, a diagonal bar 2004, a push rod 2003, a transmission spring 2005, a limiting rod 2006, a limiting hole 2011, a disc 2008, a return spring 2007, a spring plate 2009, and a transmission block 2010. The connecting column 2001 penetrates the side wall of the long plate 1902 and is slidably connected at the penetration point. One end of the connecting column 2001 is fixed to the push plate 2002, and the other end of the connecting column 2001 is hinged to the diagonal bar 2004. The end of the long plate 1902 penetrates the push rod 2003 and is slidably connected at the penetration point. The diagonal bar 2004 is hinged to the push rod 2003, and the diagonal bar 2004 is away from the push rod 2003. One end of the filter plate 7 is hinged to the connecting column 2001. The side wall of the filter box 1 is penetrated by the limiting rod 2006, and the penetration is slidably connected. The side wall of the filter plate 7 is provided with a limiting hole 2011. The outer wall of the limiting rod 2006 is in contact with the inner wall of the limiting hole 2011. A spring plate 2009 is fixed at the bottom of the filter plate 7. The side of the spring plate 2009 away from the filter plate 7 is fixed to the inner wall of the filter box 1. A disc 2008 is fixed on the outer wall of the limiting rod 2006. A return spring 2007 is fixed on the side wall of the disc 2008. The side of the return spring 2007 away from the disc 2008 is fixed to the side wall of the filter box 1. A transmission block 2010 is fixed at the end of the limiting rod 2006.

[0037] Furthermore, the original state of the spring sheet 2009 is a stretched and deformed state. When the limiting rod 2006 moves out of the limiting hole 2011, it can release the limiting of the filter plate 7. Through the cooperation of the spring sheet 2009, the spring sheet 2009 can drive the filter plate 7 to rotate downward, thereby causing the filter plate 7 to tilt, which facilitates the discharge operation of the filter plate 7.

[0038] In this embodiment, when the moving frame 10 moves back and forth, it drives the L-shaped connecting rod 1901 to move back and forth on the top of the filter box 1. This causes the L-shaped connecting rod 1901 to move the long plate 1902, thereby causing the dispersing rod 1903 to disperse the paint material accumulated on the filter plate 7, thus facilitating the screening operation of the filter plate 7. When the long plate 1902 moves back and forth, it causes the inclined block 1908 to move. When the inclined block 1908 moves to contact the inclined surface of the triangular block 1909, the inclined block 1908 will be subjected to a squeezing force towards the auxiliary rod 190. 4. The inclined block 1908 is moved to press the movable rod 1910 to rotate at the hinge, thereby causing the movable rod 1910 to press the auxiliary rod 1904 to move upward, causing the connecting seat 1905 to drive the connecting spring 1907 to compress, and causing the striking ball 1906 to move away from the filter plate 7. When the inclined block 1908 moves to a position where it does not contact the triangular block 1909, the connecting spring 1907 is in a compressed state, thereby causing the connecting spring 1907 to drive the connecting seat 1905 to move downward, so that the striking ball 1906 can strike the top of the filter plate 7, improving the screening efficiency and preventing the filter plate 7 from clogging.

[0039] When the filter plate 7 becomes clogged with excessive raw material and the height of the coating material exceeds that of the long plate 1902, and the long plate 1902 moves, the push plate 2002 will come into contact with the coating material. This will cause the push plate 2002 to be subjected to compressive force, moving it closer to the long plate 1902. This will cause the connecting column 2001 to move inward into the long plate 1902, compressing the inclined rod 2004. The inclined rod 2004 will then rotate at the hinge, thereby compressing the push rod 2003. Moving the long plate 1902 outwards stretches the transmission spring 2005. When the push rod 2003 moves out of the long plate 1902, it presses against the transmission block 2010, causing the transmission block 2010 to move the limiting rod 2006 out of the limiting hole 2011. The limiting rod 2006 then moves the disc 2008, causing the disc 2008 to pull the return spring 2007, releasing the limit on the filter plate 7. Because the spring plate 2009 is in a stretched state, it allows the spring to... The reed 2009 drives the filter plate 7 to rotate downwards, causing it to tilt. This allows the raw material on the filter plate 7 to be quickly discharged from the opening on the right side of the filter box 1. After the raw material on the filter plate 7 is discharged, the push plate 2002 is not subjected to pressure, and through the cooperation of the transmission spring 2005, the transmission spring 2005 drives the push rod 2003 to move and reset towards the long plate 1902. This causes the inclined rod 2004 to press the push rod 2003 and the push plate 2002 to reset. When the push rod 2003 resets... Because the push rod 2003 does not compress the transmission block 2010, and because the return spring 2007 is in a stretched state, the limiting rod 2006 will abut against the arc surface of the filter plate 7. By manually moving the filter plate 7 upward, the filter plate 7 pulls the spring plate 2009 to undergo tensile deformation. When the filter plate 7 rotates to the point where the limiting hole 2011 is aligned with the limiting rod 2006, the limiting rod 2006 extends into the limiting hole 2011 through the cooperation of the return spring 2007, thereby positioning the filter plate 7.

The end of the movable rod away from the auxiliary rod is hinged to the top of the inclined block. The inner wall of the filter box is fixed with multiple sets of triangular blocks arranged in a linear array; When the long plate moves back and forth, it causes the inclined block to move as well. When the inclined block moves to contact the inclined surface of the triangular block, it is squeezed and moves towards the auxiliary rod. The inclined block squeezes the movable rod and rotates at the hinge. The movable rod squeezes the auxiliary rod and moves the connecting seat upward, which in turn compresses the connecting spring, causing the striking ball to move away from the filter plate. When the inclined block moves to a position where it is no longer in contact with the triangular block, the connecting spring causes the connecting seat to move downward, and the striking ball strikes the top of the filter plate.

The side of the return spring away from the disc is fixed to the side wall of the filter box. A transmission block is fixed to the end of the limiting rod. When the push rod moves out of the long plate, it presses against the transmission block, causing the transmission block to move the limiting rod out of the limiting hole, and the limiting rod to move the disc. The spring sheet is initially in a stretched and deformed state. When the limiting rod moves out of the limiting hole, it releases the limiting effect on the filter plate. Through the cooperation of the spring sheet, the spring sheet drives the filter plate to rotate downward, thereby causing the filter plate to tilt.
