[0037] Reference Figure 1 - Figure 3The interior of the fixed frame 32 is provided with an opening and closing component 36, which includes a movable groove 361. The movable groove 361 is opened on the inner wall of the fixed frame 32. The upper surface of the movable groove 361 is provided with a feed channel 362. The feed channel 362 is in the shape of a long strip, and the distance between the two feed channels 362 is greater than the width of a single feed channel 362. The top of the fixed frame 32 is provided with a triangular prism-shaped protrusion between the two feed channels 362. The setting of the protrusion makes it easier for the oil to enter the interior of the fixed frame 32. The inner wall of the movable groove 361 is slidably connected with a movable plate 363. A cylindrical groove is provided inside the shell 1, and grooves with a longest length slightly larger than the width of the feed channel 362 are provided on the left and right sides of the cylindrical groove of the shell 1. The shape of the groove is set to ensure that when the fixed frame 32 is rotated to a horizontal state, there is movable space for the movable plate 363. The end of the movable plate 363 close to the rotating shaft 315 is elastically connected to the inner wall of the movable groove 361 through a spring four 364. One end of the spring four 364 is fixedly connected to the end of the movable plate 363 close to the rotating shaft 315, and the other end of the spring four 364 is fixedly connected to the inner wall of the movable groove 361.

[0038] Reference Figure 1 - Figure 3 The bottom end of the filter plate 33 is fixedly connected with an insert block 37, which is triangular in shape and matches the shape of the slot 355. A rectangular groove is provided on the inner wall of the shell 1 below the cylindrical groove, and the front-to-back width of the rectangular groove of the shell 1 is smaller than the front-to-back width of the cylindrical groove. A baffle 4 is fixedly connected to the inner wall of the shell 1, which is arranged in the middle of the rectangular groove of the shell 1, and the top of the baffle 4 is arranged to be an arc shape with the same curvature as the cylindrical groove opened in the shell 1. A drawer 5 is slid on the inner wall of the shell 1 on the right side of the baffle 4, and an oil outlet pipe 6 is fixedly connected to the inner wall of the shell 1 on the left side of the baffle 4.

[0039] Working principle: When in use, cutting oil containing debris enters the interior of the housing 1 through the oil inlet pipe 2 and moves downward under the action of gravity, thereby entering the interior of the left fixed frame 32 and passing through the filter plate 33.

[0040] When more debris accumulates on the filter plate 33, the weight of the filter plate 33 increases, so that the filter plate 33 can overcome the elastic force of the second spring 34 and move downward, so that the insert block 37 moves downward and enters the interior of the slot 355, so that the insert block 37 can push the inner wall of the slot 355, thereby driving the clamping block 352 to move in the direction away from the clamping slot 354.

[0041] When the card block 352 leaves the card slot 354, the rotation of the rotating shaft 315 is not limited, so the motor 311 drives the rotating disc 312 to rotate, and when the rotating disc 312 rotates to the point that the driving block 314 is just inside the force receiving groove 317, the driving block 314 extrudes the inside of the force receiving groove 317 to make the force receiving block 316 rotate, thereby making the rotating shaft 315 rotate.

[0042] When the rotating shaft 315 drives the fixed frame 32 originally in the left horizontal position to rotate downward to the slightly wide part of the cylindrical groove above the shell 1, the moving plate 363 is extruded by the inner wall of the shell 1 to enter the inside of the moving groove 361, so that the groove part of the moving plate 363 is in a different position from the inlet channel 362, and therefore the impurities inside the fixed frame 32 cannot fall out at this time.

[0043] When the rotating shaft 315 rotates by 90 degrees, the fixed frame 32 originally in the vertical direction above rotates to the left horizontal position at this time, and when the fixed frame 32 is just in this position, the card block 352 moves outward under the elastic force of the spring three 353, so as to enter the card slot 354, so that the left fixed frame 32 cannot continue to move at this time, and therefore the rotating shaft 315 cannot rotate at this time.

[0044] When the motor 311 drives the rotating disc 312 to rotate again at this time, the spherical surface of the driving block 314 is forced to enter the inside of the movable groove 313, thereby forming idling, so as not to damage the equipment.

[0045] At the same time, the fixed frame 32 in the right horizontal position at this time is rotated to the right slightly wide position, so that the moving plate 363 moves outward under the elastic force of the spring four 364, so that the groove of the moving plate 363 is in the same vertical position as the inlet channel 362, and therefore the impurities inside the fixed frame 32 can fall out at this time, and at the same time, the filter plate 33 moves downward under the elastic force of the spring two 34, so as to better push out the impurities inside the fixed frame 32.

[0046] When the staff needs to clean the debris, the drawer 5 can be taken out to clean the debris.

[0047] Finally, it should be pointed out that the above description is only a preferred embodiment of the present application and is not intended to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, and for those skilled in the art, the technical solutions recorded in the foregoing embodiments can be modified or some technical features can be replaced by equivalents, and any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
