Technical Field
[0001] The utility model relates to the technical field of water-based paint roller applicators, in particular to a drawable water-based paint roller applicator. Background Technique
[0002] Water-based paint is a truly environmentally friendly paint coating that has emerged in recent years and is gradually being popularized in all industries and fields. The most common use of water-based paint is for indoor and outdoor decoration.
[0003] In the existing roller applicator, there is a shielding cover that stores the paint falling from the roller applicator to prevent the paint from falling onto the staff from the roller applicator. However, when using the existing roller applicator to paint the interior wall, the amount of paint carried inside the shielding cover increases, resulting in the entire roller applicator becoming heavier and burdening the staff. Therefore, a drawable water-based paint roller applicator needs to be designed. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose a drawable water-based paint roller applicator.
[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A drawable water-based paint roller applicator includes a box body and a fixing frame. Inside the fixing frame, a hopper is fixedly connected. The lower end of the hopper is fixedly connected with a hollow support cylinder. The bottom end of the hollow support cylinder is fixedly connected with a first connecting pipe. The first connecting pipe extends downward into the box body and is fixedly connected to the box body through a fastener. Inside the fixing frame, two left-right distributed rotating shafts are rotatably connected. A roller is fixedly connected between the two rotating shafts. A plurality of circular holes are formed on the circumferential surface of the roller. A roller coating is fixedly installed on the circumferential surface of the roller. The lower half parts of the roller and the roller coating are both located inside the hopper. The rotating shaft on the right end is a hollow shaft. Inside the box body, a paint pump is fixedly installed. The discharge end of the paint pump is fixedly connected with a second connecting pipe. The second connecting pipe penetrates through the box body to the right and extends into the rotating shaft on the right end, and is rotatably connected with the right rotating shaft. The second connecting pipe is communicated with the roller through the right rotating shaft.
[0006] Further, a support seat is fixedly connected to the right end of the fixing frame. The second connecting pipe penetrates through the support seat and is fixedly connected to the support seat, and the support seat is used to support the second connecting pipe.
[0007] Further, a flexible sleeve is fixedly installed on the circumferential surface of the hollow support cylinder.
[0008] Further, two left-right distributed inclined surfaces are arranged inside the hopper, and the two inclined surfaces are respectively located at the left and right ends of the hollow support cylinder.
[0009] Furthermore, the fastener includes a mounting plate, a threaded rod, and a nut. The circumferential surface of the first connecting pipe is fixedly connected to the mounting plate. The upper end of the box body is fixedly connected to the threaded rod. A through hole for the threaded rod to pass through is provided on the upper end surface of the mounting plate. The circumferential surface of the threaded rod is threadedly connected to the nut, and the nut is located above the mounting plate.
[0010] Furthermore, a feeding pipe is fixedly connected to the upper end of the box body, and a discharging pipe and a valve are fixedly connected to the left side of the box body, and the valve is fixedly connected to the discharging pipe.
[0011] The utility model has the following beneficial effects:
[0012] 1. Compared with the prior art, in the extractable water-based paint roller coater, through the mutual cooperation of the hopper, the hollow support cylinder, and the first connecting pipe, the water-based paint inside the hopper can be discharged outwards along the hollow support cylinder and the first connecting pipe. In this way, a large amount of water-based paint is not likely to accumulate inside the hopper. At this time, the roller coater composed of the roller coating, the roller, the fixing frame, and the hopper is not likely to have the problem of bringing a burden to the staff due to its increasing weight.
[0013] 2. Compared with the prior art, in the extractable water-based paint roller coater, through the function of the hopper, the water-based paint falling from the roller coating can be stored, avoiding the water-based paint from falling from the roller coating onto the staff and causing the staff's clothes to get dirty.

Detailed implementation manners
[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0023] Refer to Figures 1-6 , a draw-type water-based paint roller coater provided by the utility model includes a box body 1 and a fixed frame 8. A hopper 9 is fixedly connected inside the fixed frame 8. The lower end of the hopper 9 is fixedly connected with a hollow support cylinder 7. The bottom end of the hollow support cylinder 7 is fixedly connected with a first connecting pipe 5. The first connecting pipe 5 extends downward into the box body 1 and is fixedly connected with the box body 1 through a fastener. Two rotating shafts 16 distributed left and right are rotatably connected inside the fixed frame 8. A roller 11 is fixedly connected between the two rotating shafts 16. A plurality of circular holes 12 are formed on the circumferential surface of the roller 11. A roller coating 10 is fixedly installed on the circumferential surface of the roller 11. The lower half parts of the roller 11 and the roller coating 10 are both located inside the hopper 9. The rotating shaft 16 at the right end is a hollow shaft. A paint pump 14 is fixedly installed inside the box body 1. The discharge end of the paint pump 14 is fixedly connected with a second connecting pipe 6. The second connecting pipe 6 penetrates through the box body 1 to the right and extends into the rotating shaft 16 at the right end, and is rotatably connected with the right rotating shaft 16. The second connecting pipe 6 is communicated with the roller 11 through the right rotating shaft 16. During operation, the utility model can discharge the water-based paint inside the hopper 9 along the hollow support cylinder 7 and the first connecting pipe 5, so that a large amount of water-based paint is not likely to accumulate inside the hopper 9. At this time, the roller coater composed of the roller coating 10, the roller 11, the fixed frame 8 and the hopper 9 is not likely to have the problem of bringing a burden to the staff due to its increasing weight.
[0024] Furthermore, as Figure 2 shown, a support seat 20 is fixedly connected to the right end of the fixed frame 8. The second connecting pipe 6 penetrates through the support seat 20 and is fixedly connected with the support seat 20, and the support seat 20 is used to support the second connecting pipe 6. During operation, under the action of the support seat 20, the second connecting pipe 6 can be more stably installed in the rotating shaft 16.
[0025] Furthermore, as Figure 1As shown, a flexible sleeve 4 is fixedly installed on the circumferential surface of the hollow support cylinder 7. During operation, the presence of the flexible sleeve 4 facilitates the operator to hold the hollow support cylinder 7 and use the roller coating 10 to decorate the interior wall.
[0026] Furthermore, as Figure 4 shown, two inclined surfaces 13 are arranged inside the hopper 9 and are distributed left and right. The two inclined surfaces 13 are respectively located at the left and right ends of the hollow support cylinder 7. During operation, the presence of the inclined surfaces 13 facilitates the water-based paint inside the hopper 9 to concentrate and enter the hollow support cylinder 7 along the inclined surfaces 13, and finally drain into the box body 1 along the first connecting pipe 5.
[0027] Furthermore, as Figure 4 shown, the fastener includes a mounting plate 17, a threaded rod 18 and a nut 19. The circumferential surface of the first connecting pipe 5 is fixedly connected with the mounting plate 17, the upper end of the box body 1 is fixedly connected with the threaded rod 18, a through hole for the threaded rod 18 to pass through is opened on the upper end surface of the mounting plate 17, the circumferential surface of the threaded rod 18 is threadedly connected with the nut 19, and the nut 19 is located above the mounting plate 17. During operation, under the action of the fastener, the first connecting pipe 5 can be firmly connected to the box body 1 to ensure that the water-based paint inside the hopper 9 can more smoothly enter the box body 1 along the hollow support cylinder 7 and the first connecting pipe 5.
[0028] Furthermore, the heights of the hopper 9 and the hollow support cylinder 7 are higher than the height of the box body 1. When the position of the wall to be painted is lower than the box body 1, the nut 19 should be removed along the threaded rod 18, and then the first connecting pipe 5 should be pulled out of the box body 1 so that the bottom end of the first connecting pipe 5 hangs down naturally. At the same time, the hopper 9 should always be located above the first connecting pipe 5 and the hollow support cylinder 7. In this way, when painting the wall, the water-based paint inside the hopper 9 can smoothly drain out along the hollow support cylinder 7 and the first connecting pipe 5.
[0029] Furthermore, as Figure 4 shown, a feeding pipe 2 is fixedly connected to the upper end of the box body 1, a discharge pipe 15 and a valve 3 are fixedly connected to the left side of the box body 1, and the valve 3 is fixedly connected to the discharge pipe 15. During operation, the presence of the feeding pipe 2 facilitates injecting water-based paint into the box body 1 at any time. When the water-based paint inside the box body 1 is no longer needed and needs to be discharged, the valve 3 can be opened to discharge it from the discharge pipe 15.
[0030] Working principle:
[0031] During use, the paint pump 14 operates to allow the water-based paint inside the box body 1 to enter the drum 11 along the second connecting pipe 6 and the right-side rotating shaft 16, and immerse into the roller coating layer 10 along a plurality of circular holes 12. Then, the staff can hold the hollow support cylinder 7 to paint the indoor wall surface. During the painting process, the water-based paint that falls from the roller coating layer 10 will be received by the hopper 9, flow into the first connecting pipe 5 along the hollow support cylinder 7, and finally enter the box body 1. In this way, a large amount of water-based paint is not likely to accumulate inside the hopper 9. At this time, the roller coater composed of the roller coating layer 10, the drum 11, the fixing frame 8, and the hopper 9 is not likely to cause a problem of increasing burden on the staff due to its increasing weight.
[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
