Therefore, a filter with an automatically wound filter screen is introduced. Chinese Utility Model Patent CN213492659U discloses a new type of automatic winding filter, which includes a feeding mechanism, a bracket, a material collecting mechanism and a base. The material collecting mechanism includes a reduction motor, a reel structure and two mounting plates. When disassembling the dirty filter material, only one end of the filter material needs to be lifted, and the whole filter material can be directly pulled out to be separated from the inner hollow sleeve, so that the disassembly of the material collecting mechanism becomes very simple and fast, and thus the replacement of the filter material also becomes very fast, saving the maintenance time. However, this technical solution may have problems such as the filter screen being loose, shifted, and not completely attached, which affects the filtering effect. Content of the Utility Model

By setting a pressure component, the surface tension of the filter screen can be adjusted and it has a limiting effect, avoiding the influence of the filter screen on the filtering effect due to problems such as relaxation and displacement.

[0004] Technical Solution: To achieve the above objective, a wound filter screen filter disclosed by the utility model includes a frame body, and a feeding roller, a material collecting roller and a pressure component connected inside the frame body; the feeding roller and the material collecting roller are wound with a filter screen on their surfaces, and the pressure component is connected between the feeding roller and the material collecting roller and is connected to the surface of the filter screen.

[0005] Furthermore, the pressure component includes a first plate body, a second plate body and a locking component; the first plate body and the second plate body form a frame structure and are connected by the locking component.

[0006] Furthermore, the first plate body is distributed along the extension direction of the filter screen, and its bottom surface is in contact with the top surface of the filter screen, and the second plate body is connected to the upper surface of the first plate body and the two are vertically distributed.

[0007] Furthermore, the locking component passes through the second plate body and is connected to the frame body. The locking component is connected to the end of the second plate body and is far from the connection between the first plate body and the second plate body.

[0008] Furthermore, grooves are provided at both ends of the first plate body, and the end of the second plate body is clamped in the grooves.

[0009] Furthermore, a spring is sleeved and connected on the surface of the locking component, and the spring is in pressing connection with the second plate body.

[0010] Furthermore, the filter can be connected to a device with a fan, and the filter screen covers the surface of the air inlet.

[0011] By setting the pressure-applying component, the present utility model can apply an appropriate pressure to the surface of the filter screen, ensuring that the filter screen remains tightly attached during the winding process, reducing air leakage during air flow, and thus improving the filtration efficiency. At the same time, the pressure-applying component can also make the filter screen more stable during the winding process, less likely to shift or loosen, contributing to maintaining the integrity of the overall structure and extending the service life.
