The front end of the slider 82 is threadedly connected with a bolt 83. By rotating the bolt 83, the front end of the slider 82 no longer clamps the outside of the slide groove 81. At this time, the slider 82 can be slid to adjust the amplitude of the reciprocating vibration. The further outward the adjustment is made, the greater the amplitude of the reciprocating vibration is. After the adjustment is completed, it is fixed by tightening the bolt 83. The front end of the bolt 83 is rotatably provided with a hinge plate 84, and one end of the hinge plate 84 is provided with a No. 1 slide rod 85, and one end of the No. 1 slide rod 85 extends to the inside of the housing 1 through the sliding hole.
[0049] Example 2, the filtering device of the water-based UV light-curing floor coating provided in Example 1 is further optimized, specifically, as follows Figure 2 , Figure 5 and Figure 6 As shown, the clamping assembly includes a lower frame 61 located inside the shell 1, an upper frame 62 is provided at the top of the lower frame 61, elastic slots 63 are fixedly provided at the four corners of the top of the lower frame 61, and clamping balls 64 are fixedly provided at the four corners of the bottom of the upper frame 62.

When disassembly is required, the upper frame 62 is pulled to separate it from the lower frame 61.
[0050] Further, such as Figure 2 , Figure 5 and Figure 6 As shown, the clamping assembly also includes four No. 1 springs 65, which are fixed at the four corners of the upper frame 62 and staggered with the position of the clamping ball 64.

[0051] Example 3, the filtering device of the water-based UV light-curing floor coating provided in Example 1 or 2 is further optimized, specifically, as follows Figure 2-3As shown, the auxiliary assembly includes two No. 1 slide cylinders 91 fixedly connected to the inside of the housing 1, the No. 1 slide cylinder 91 is located on the other side of the slide hole, the No. 1 slide rod 85 slides inside the No. 1 slide cylinder 91, and one end of the No. 1 slide rod 85 is fixedly connected to the lower frame 61.

When the motor 73 is started, the adjustment assembly and the clamping assembly are driven to operate, so that the No. 2 slide bar 94 slides back and forth inside the No. 2 slide cylinder 92. When the No. 2 slide bar 94 slides into the No. 2 slide cylinder 92, the elastic force of the No. 2 spring 93 repels it outward until the No. 2 slide bar 94 slides in the opposite direction, and the No. 2 spring 93 assists it in pushing outward, relying on this inertia to assist the motor 73 in running.
[0053] Further, such as Figure 1 As shown, the connecting component includes four No. 2 protrusions 42, and the four No. 2 protrusions 42 are fixed on both sides of the top shell 2.

[0054] The use process of the filtering device for water-based UV light-curing floor coating provided by the utility model is as follows:
[0055] When the filter needs to be disassembled, the filter is placed on the No. 2 anti-skid pad 67 in the lower frame 61 during installation. The upper frame 62 and the lower frame 61 are merged by inserting the card ball 64 in the upper frame 62 into the elastic card groove 63. The No. 1 anti-skid pad 66 and the No. 2 anti-skid pad 67 are in contact, and the filter in the middle is fixed by the spring. When disassembling, the upper frame 62 is pulled apart from the lower frame 61. When the vibration amplitude needs to be adjusted, the bolt 83 is turned so that its front end no longer clamps the outside of the slide groove 81. At this time, the slider 82 can be slid to adjust the amplitude of the reciprocating vibration. The degree of reciprocating vibration is adjusted further outward, and the amplitude of the reciprocating vibration is larger. After the adjustment is completed, it is fixed by tightening the bolt 83; when it is necessary to start the device to filter the paint, a collection bucket for collecting the paint is placed at the lower end of the discharge port 3, and the motor 73 is started by the switch to make the No. 1 gear 71 drive the No. 2 gear 72 to rotate, so that the filter net in the clamping assembly can be reciprocated through the adjustment component, and the paint is poured from the funnel to pass through the two layers of filter nets for filtering to achieve a better filtering effect, and then flows out through the discharge port 3 and enters the collection bucket for collection.
