Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a roller coating machine for interior and exterior wall paint. Background Art

[0002] During home renovations, wall painting typically requires the use of a roller brush. When using a traditional roller brush for wall painting, workers must first move the paint bucket to the wall to be painted, then dip the roller brush into the bucket to pick up the paint, and then lift the roller brush to apply the paint. This entire process requires workers to constantly move the paint bucket, frequently bend over to dip the roller brush into the bucket, and then lift the roller brush to the wall. This can even require workers to climb indoors or work outdoors from hanging baskets and ropes. This construction method is labor-intensive and inefficient. Furthermore, the constant dipping and unloading of the roller brush can lead to paint dripping, resulting in wasteful material. Furthermore, once the roller brush picks up a large amount of paint and comes into contact with the wall, the fluidity of the paint causes the paint to flow downwards, preventing the roller brush from evenly distributing the paint, impacting the quality of the wall painting. To address this issue, we have developed a roller coating machine for interior and exterior wall paint. Utility Model Content

[0003] The utility model provides an internal and external wall paint roller coating machine, which solves the problems raised by the above background technology.

[0010] The utility model has the following beneficial effects:

[0011] 1. The interior and exterior wall paint roller coating machine can ensure that a part of the paint on the bristles of the brush can enter the roller part under the action of the squeezing force during painting, and then penetrate into the bristles of the brush again through the roller part, so that the paint can be filled into the bristles of the brush again for painting, avoiding the excess paint on the bristles from flowing directly down, thereby ensuring the uniformity of painting and the effective use of paint.

[0012] 2. The interior and exterior wall paint roller coating machine can rotate the linkage wheel through the transmission of the connecting block, and the drive wheel can rotate through the transmission of the transmission belt.

[0019] 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.

[0020] See also Figures 1 to 4 The roller coating machine for interior and exterior wall paint comprises a roller brush 1, a handle 2 and a bracket 3. The roller brush 1 is mounted on the bracket 3, and a handle 2 is fixedly connected to the bottom of the bracket 3. The bracket 3 is used to drive the roller brush 1 to move and paint. The roller brush 1 comprises a bristle portion 5 and a roller portion 6. The bristle portion 5 is wrapped around the outside of the roller portion 6, and the roller portion 6 is hollow. A plurality of through holes are opened on the roller portion 6. The bristle portion 5 can be dipped in paint and then the wall is painted. When painting, as the bracket 3 pushes, the bristle portion 5 can rotate, thereby enabling the roller portion 6 to rotate. When painting, the bristle portion 5 generates an extrusion force, and the bristle portion 5 is pressed against the paint. A portion of the paint enters the roller portion 6 through the through hole on the roller portion 6 and penetrates the bottom of the brush portion 5, so that the paint does not flow down directly, thereby improving the utilization rate of the paint. A cavity 8 opposite to the outer side of the brush portion 5 is opened inside the top of the bracket 3, so that the paint in the cavity 8 can fill the brush portion 5, and the brush portion 5 is supplied with paint in time. The handle 2 and the interior of the bracket 3 are commonly connected with a connecting pipe 4, one end of the connecting pipe 4 is connected to the cavity 8, and the end of the connecting pipe 4 that extends out is connected to a water pump. Under the action of the water pump, the paint in the paint bucket can be transported to the cavity 8 through the connecting pipe 4 for temporary storage, thereby making the addition of paint more convenient.

[0021] See also Figures 1 to 5 The two sides of the bracket 3 are movably covered with linkage wheels 12, and the linkage wheels 12 can rotate at a fixed position on the bracket 3. The inner side of the roller part 6 is fixedly connected with a connecting rod 7, and the connecting rod 7 can rotate together with the roller part 6. The two ends of the connecting rod 7 are movably connected with a cross-shaped connecting block 11, and the connecting block 11 can move along the fixed track on the connecting rod 7.

[0022] See also Figures 1 to 4One end of the connecting block 11 extends out and penetrates and connects with the linkage wheel 12, so that the connecting block 11 can smoothly drive the linkage wheel 12 to rotate when plugged in, and the connecting block 11 can be moved into the connecting rod 7 to facilitate the disassembly and assembly of the roller brush 1. The other end of the connecting block 11 is fixedly connected to the first spring 9, and one end of the first spring 9 is fixed to the connecting rod 7. Under the action of the elastic force of the first spring 9, the connecting block 11 can be smoothly connected with the linkage wheel 12.

[0023] See also Figures 1 to 5 The bracket 3 is connected to a driving wheel 14 through an axle pin, forming a hinge structure with the axle pin as the rotating axis, so that the driving wheel 14 can rotate at a fixed position on the bracket 3, and the middle of the driving wheel 14 and the middle of the linkage wheel 12 are jointly connected with a transmission belt 13. Under the transmission of the transmission belt 13, the linkage wheel 12 can drive the driving wheel 14 to rotate.

[0024] See also Figures 1 to 5 A baffle 10 is movably connected to the bracket 3, and the baffle 10 can move along a fixed track in the bracket 3. The middle of the baffle 10 can close the cavity 8, and two outlets are provided on both sides of the baffle 10. When the outlet on the baffle 10 moves to be relatively aligned with the cavity 8, the paint in the cavity 8 can be smoothly added to the bristle part 5, and the bottom of both ends of the baffle 10 is provided with a convex portion, and the outer side of the driving wheel 14 is provided with a plurality of spaced driving parts, which can contact the convex portion, and then the driving part can intermittently push the convex portion, so that the baffle 10 can intermittently open the cavity 8, so that it can evenly discharge the material.

[0025] See also Figures 1 to 5 A second spring 15 is fixedly connected to both sides of one end of the baffle 10, and one end of the second spring 15 is fixedly connected to the bracket 3. Under the action of the elastic force of the second spring 15, the baffle 10 can automatically return to its original position to close the cavity 8.

[0026] In summary, when the interior and exterior wall paint roller coating machine is used, the connecting block 11 is pressed to move it into the connecting rod 7, and then the roller brush 1 is installed on the bracket 3. Under the action of the elastic force of the first spring 9, the connecting block 11 is plugged into the linkage wheel 12, so that the roller brush 1 can be stably installed, and then under the action of the water pump, the paint can be transported to the cavity 8 through the connecting pipe 4. When painting, the bristle part 5 contacts the wall, the bristle part 5 paints the wall, and the bristle part 5 can rotate when painting, and then drives the linkage through the connecting block 11. The wheel 12 rotates and is driven by the transmission belt 13, so that the driving wheel 14 can rotate. The driving part on the driving wheel 14 can intermittently contact and push the convex part, thereby enabling the baffle 10 to move, so that the outlet on the baffle 10 can be aligned with the cavity 8, so that the paint in the cavity 8 can be discharged and added to the bristle part 5. At the same time, the bristle part 5 is squeezed when painting, and a part of the paint on the bristle part 5 enters the roller part 6 through the through hole on the roller part 6 and penetrates the bottom of the bristle part 5, so that the paint can be reused.
