[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figures 1-12 The present invention provides a dust-filtering microfiber leather softening drying machine, comprising a drying body 1, wherein a high-pressure fan with a heater is provided in the drying body 1, and a horizontal wind box and an air duct 2 are connected above the high-pressure fan. The microfiber leather moves back and forth with the air flow in the horizontal wind box. Regarding the arrangement of the horizontal wind box, the air duct 2 and the high-pressure fan, reference is made to a strong airflow continuous open-width softening drying machine with prior art publication number CN202648330U.

[0033] The working principle of the dryer is as follows: the strong airflow generated by the high-pressure fan causes the microfiber leather to be rubbed and dried in the horizontal air box. The fine fiber dust generated in the process enters multiple filter components 3 (the filter components 3 are located in the air duct 2) with the airflow. The bottom plate 301 and the blocking plate 302 in the filter components 3 rotate in coordination to gradually reduce the filter aperture, effectively capturing and filtering dust of different sizes. The rotating wheel 4 and the rotating rod 7 drive the filter components 3 to switch cyclically, ensuring that the filtering effect is adjusted in real time with changes in the amount of dust.

[0034] During the rotation switching, the cooperation of the sliding column 18 and the sliding groove 15 accurately controls the rotation angle of the filter component 3 to avoid the existence of gaps at the joints between the three filter plates 303 in the front after the switching is completed, causing dust to pass through the gaps without being filtered. That is, through the cooperation of the movable disk 14 and the rotating plate 13, it is ensured that the filter component 3 rotates 120 degrees each time to maintain no gaps between the filter plates 303. The squeezing and suction actions of the plug-in tube 21 and the blocking block effectively remove the dust accumulated inside the filter component 3, ensuring the continuous high efficiency of the filtration system and preventing microfiber leather pollution. Finally, the filtered airflow is discharged to achieve the goal of protecting the environment and improving the drying quality and efficiency.

[0035] In the present application, a plurality of filter assemblies 3 are provided in the air duct 2, and the filter assembly 3 specifically includes a base plate 301 and a sealing plate 302. The base plate 301 is a polygonal plate (for example, a triangular plate), and filter plates 303 are fixedly mounted on the three sides of the base plate 301. The adjacent sides of the three filter plates 303 are fitted together, and the sealing plate 302 (the sealing plate 302 is also a polygonal plate) sliding in the three filter plates 303 forms a closed filtering environment.

[0036] After the dust enters the filter plate 303 located in the front, it enters the three filter plates 303. Since the mesh aperture sizes of the multiple filter plates 303 assembled to each other are in a decreasing relationship, the dust enters the three filter plates 303. Due to mechanical activity and thermal stress, small fiber particles fall off to form dust. At the beginning, the dust that is separated is relatively large. Gradually, as the mechanical activity and thermal stress of the microfiber leather increase, the dust gradually becomes finer. In this application, by rotating the filter assembly 3, the filter plates 303 with smaller filtering meshes are switched to the front one by one, so that the filter plates 303 are adaptively switched as the dust changes during the actual drying process, ensuring that the filtered and collected dust enters the bottom plate 301.

[0037] Among them, in this application, the dust that is too fine (fine dust below the mesh size of the filter plate 303) is not filtered, and this part is filtered by the liquid filtration method outside the drying body 1 (the gas passes through the liquid to filter the dust). This application does not make any improvements to this and will not elaborate on it.

[0038] When the filter assembly 3 is switched by rotating the rotating wheel 4, the filter assembly 3 rotates 120 degrees each time, driving the filter plate 303 to switch, and the three filter plates 303 of the three filter assemblies 3 cooperate with each other. There is no gap between each adjacent two filter plates 303 of the three filter plates 303 located in the front, preventing dust from passing through the gap between the two filter plates 303.

[0039] Description of switching filter assembly 3: The bottom of the base plate 301 is fixedly connected to a rotating wheel 4 that passes through the air duct 2, and the outer surface of the air duct 2 is connected and fixed to a fixing frame 8. The rotating rod 7 is rotatably connected to the fixing frame 8, and the rotating rod 7 rotates, driving the meshing wheel 10 fixed to the rotating rod 7 to rotate in its original position, and a limiting ring 9 is fixedly connected to the fixing frame 8. The rotating wheel 4 rotates in its original position within the limiting ring 9, and the rotating meshing wheel 10 causes the rotating wheel 4 to rotate. The central axis of the rotating wheel 4 passes through the air duct 2 and is connected and fixed to the base plate 301, thereby rotating the filter assembly 3.

[0040] The meshing wheel 10 and the rotating wheel 4 are preferably bevel gears meshing with each other.

[0041] Regarding how to ensure that the angles of switching the filter assembly 3 are consistent so that no gaps appear between the filter plates 303 located in the front of the filter assembly 3.

[0042] A base 12 is fixedly installed at the end of the air duct 2, and a rotating plate 13 and a movable disk 14 are rotatably connected to the base 12. The rotating rod 7 at the end passes through the base 12 and is fixedly connected to the middle part of the rotating plate 13. The central axis of the movable disk 14 is rotatably connected to the base 12. The movable disk 14 is rotated manually or by setting a control motor. A connecting plate 17 is fixedly connected to the middle part of the movable disk 14, and a sliding column 18 is provided at the end of the rotating plate. It is worth noting that a movable groove 16 is opened on the movable disk 14, and the sliding column 18 is located in the position of the movable groove 16.

[0043] A sliding groove 15 is provided on the rotating plate 13, and the edge of the rotating plate 13 is in an arc-shaped structure. The movable disk 14 drives the connecting plate 17 to rotate, thereby causing the sliding column 18 to perform a circular motion. When the sliding column 18 is close to the sliding groove 15, the movable groove 16 corresponds to the position of the sliding groove 15, and the movable groove 16 corresponds to the position of the arc-shaped edge of the rotating plate 13.

[0044] When the slide post 18 enters the sliding groove 15, it drives the rotating plate 13 to rotate, and the rotating plate 13 drives the rotating rod 7 and the meshing wheel 10 to rotate. Then the slide post 18 moves out of the sliding groove 15. At the same time, the edge of the movable disk 14 is adaptively pressed against the arc structure of the rotating plate 13, thereby ensuring that the rotating plate 13 maintains the angle after rotating to a certain angle.

[0045] The diameter of the sliding post 18 is smaller than the width of the sliding groove 15 , which facilitates the entry of the sliding post 18 .

[0046] It is worth noting that: the end of the sliding column 18 is self-rotating with a movable plate 19, and the edge of the end of the sliding column 18 is fixedly connected to a baffle 20. The baffle 20 and one side of the movable plate 19 are made of magnetically attractive materials. Through the magnetic effect, the movable plate 19 is pressed against the baffle 20. When the sliding column 18 enters the sliding groove 15 in a clockwise circumferential direction, the movable plate 19 moves away from the baffle 20 and rotates adaptively in the sliding groove 15 without affecting the interval rotation of the rotating plate 13.

[0047] When the slide post 18 moves toward the sliding groove 15 in a counterclockwise circumferential direction, the position of the rotating plate 13 near the end of the sliding groove 15 presses the movable plate 19, causing the movable plate 19 to rotate toward the baffle 20. Due to the restriction of the baffle 20, the movable plate 19 cannot rotate, so that the slide post 18 cannot enter the sliding groove 15, ensuring that the filter plate 303 rotates in a regular manner with a decreasing mesh aperture size, that is, the filter plate 303 located in the front is switched by rotation, and the mesh aperture of the switched filter plate 303 becomes smaller and smaller. Among them, an anti-collision layer is also provided on one side of the movable plate 19, and the anti-collision layer is located between the movable plate 19 and the baffle 20 to avoid direct collision between the movable plate 19 and the baffle 20.

[0048] The top surface of the bottom plate 301 is a concave structure and is connected to the dust exhaust hole 5. A dust exhaust hole 5 is opened in the middle of the rotating wheel 4, and a sealing plug 6 is installed on the dust exhaust hole 5. When too much dust accumulates in the filter assembly 3 and needs to be cleaned, the sealing plug 6 is opened to facilitate the dust to fall from the bottom plate 301 and the dust exhaust hole 5 of the rotating wheel 4; wherein, a U-shaped rod 11 is fixedly connected between two adjacent rotating rods 7, and the U-shaped rod 11 is located below the rotating wheel 4. The U-shaped rod 11 ensures the synchronization of rotation between multiple rotating rods 7 on the one hand, and avoids space on the other hand, which facilitates cleaning of dust from the dust exhaust hole 5.

[0049] The U-shaped rod 11 performing circular motion will not touch the rotating wheel 4, thus avoiding motion interference.

[0050] A plug-in tube 21 is fixedly connected to the middle of the blocking plate 302, and the plug-in tube 21 passes through the air duct 2. Multiple plug-in tubes 21 are fixedly connected to each other, and a blocking block is plugged into the top of the plug-in tube 21. The plug-in tube 21 corresponds to the position of the dust exhaust hole 5. The blocking plate 302 is driven to move along the inside of the filter component 3 through the upper and lower movable plug-in tubes 21. The reciprocating movable blocking plate 302 squeezes the dust inside the filter component 3, and the plug-in tube 21 is movably plugged into the dust inside the filter component 3, so that the dust can fall from the dust exhaust hole 5.

[0051] The end of the plug-in tube 21 can be connected to a blowing device, which supplies air to move the inside of the filter assembly 3 through the plug-in tube 21, thereby helping dust to pass through the dust exhaust hole 5; or the dust can be sucked out of the plug-in tube 21 through the suction device. The blowing device or the suction device can be selected according to actual conditions.
