[0013] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0014] Reference Figure 1-4 , a screw machine for diaper production, including a compressor box 1, one end of the compressor box 1 is provided with an air inlet 2, the other end is provided with an air outlet pipe, the top of the air inlet 2 is detachably provided with a filter mechanism 3, a filter channel 31 is provided on the filter mechanism 3, a filter screen 32 is installed on the filter channel 31, a snap ring 33 is provided on the top of the filter mechanism 3 and the top edge of the air inlet 2, a slot 34 is provided at the bottom of the filter mechanism 3, the snap ring 33 can be snapped into the slot 34 and slidably connected to the slot 34, a groove 38 is provided on the outer side of the filter mechanism 3 and the air inlet 2, a limiting hole 35 is provided on the top of the groove 38, a limiting column 36 is fixedly provided at the bottom of the filter mechanism 3, and the outer surface of the limiting column 36 is provided with a thread and a nut 37 is screwed on it.

[0015] An air groove 4 is formed on the inner wall of the filter channel 31. A film 41 is disposed at the opening of the air groove 4. A tension test sensor 42 is disposed within the air groove 4. The test end of the tension test sensor 42 is connected to the film 41 via a pull cord 43. A sealing rubber ring is disposed within the clamping groove 34 at the portion in contact with the clamping ring 33.

[0016] When the device is in use, the limiting post 36 at the bottom of the filter mechanism 3 is inserted into the limiting hole 35 on the air inlet 2, and the snap ring 33 at the bottom of the filter mechanism 3 is snapped into the snap groove 34 at the top of the air inlet 2, and the nut 37 is tightened to connect the filter mechanism 3 to the air inlet 2 tightly. Then another filter mechanism 3 is stacked and installed on the previously installed filter mechanism 3. The filter screen on the filter mechanism 3 can be cleaned by using a handheld vacuum cleaner to absorb impurities on the surface of the filter screen (this method is more convenient and quick, but there is a problem of not cleaning thoroughly enough), or by removing it and flushing it (this method cleans more thoroughly but is not convenient and quick enough). The filter screen on the upper filter mechanism of the first layer accumulates impurities at a slower rate and can be cleaned at longer intervals, while the filter screen on the top filter mechanism accumulates impurities faster and requires more frequent cleaning; when the rotor rotates in the compressor box, air enters the air inlet from the filter channel, the gas flow rate in the filter channel is fast and the pressure is low, and the pressure in the air tank 4 is strong, so that the film 41 is squeezed toward the filter channel under the action of pressure, and the tension generated is transmitted to the tension test sensor 42 through the pull rope 43 for detection. When too many impurities accumulate on the filter screen, it will affect the gas passing efficiency, causing the flow rate to slow down, and the tension detected by the tension test sensor 42 will also become smaller. At this time, the filter screen needs to be cleaned.

[0017] The orientations or positional relationships shown in the drawings are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they should not be understood as limiting the present invention.

[0018] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0019] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
