[0034] In summary, the working principle of a paint roller with a paint collecting device for decoration in an embodiment of the present utility model: When the device needs to be used, first install the roller body 106 on the rotating shaft 105, and then install the installation cover plate 104. When using the roller body 106 to paint the wall surface, the paint dripping from the roller body 106 is caught by the collecting cover 101, effectively preventing the paint from dripping on the ground or other corresponding objects. When the roller body 106 is painting, the roller body 106 drives the rotating shaft 105 and the driving gear 202 to rotate, and the driving gear 202 drives the driven gear 205 and the ratchet disc 204 to rotate. When the driven gear 205 rotates in the reverse direction, the driven gear 205 drives the ratchet disc 204 to push the pawl 21 to descend, and the pawl 21 retracts into the limiting U-shaped frame 23. When the driven gear 205 rotates in the forward direction, the pawl 21 is reset by the return spring 22 and is stuck on the ratchet disc 204, so that the ratchet disc 204 drives the rotating disc 24 to rotate through the pawl 21. Such a setting can only make the rotating disc 24 rotate in the forward direction. When the rotating disc 24 rotates, the rotating disc 24 drives the rotating rod 301 and the reciprocating threaded rod 302 to rotate, and the reciprocating threaded rod 302 can drive the moving column 303 and the arc-shaped scraping blade 306 to move reciprocally. The arc-shaped scraping blade 306 scrapes the excess paint on the surface of the roller body 106 into the collecting cover 101, without worrying about the paint splashing due to too fast rotation, greatly reducing the waste of paint and saving the decoration cost;

[0035] The rotating disk 24 drives the conveyor belt 401 to move. The conveyor belt 401 drives the rotating rod 402 to rotate. The rotating rod 402 drives the turntable 403 and the extrusion rod 404 to rotate. The extrusion rod 404 extrudes the hose 406, causing a negative pressure at one end of the hose 406 located at the collection baffle 405. The paint is sucked in through the negative pressure generated by the hose 406. The extrusion rod 404 continuously extrudes the hose 406, and the paint can be squeezed into the collection drawer 408, preventing the paint from dripping due to excessive accumulation in the collection hood 101. At the same time, the paint is collected and reused, further reducing the waste of paint.

[0036] The above is only the preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
