Description

Technical Field

[0001] This utility model relates to the field of paint brushes, and specifically to a paint brush for paint production. Background Technology

[0002] Paint is a coating applied to the surface of an object to be protected or decorated, forming a continuous film that adheres firmly to the object.

[0003] In the production and processing of coatings, the raw materials of coatings are usually mainly resins, oils, or emulsions, which are then formulated into a viscous liquid through a series of different proportions.

[0004] In the process of applying paint, a special paint brush is often used. However, when using the paint brush, it needs to be inserted into the paint bucket multiple times so that the paint can adhere to the brush. This will reduce the efficiency of paint processing.

[0005] Existing technology 202420085773.3 discloses a paint brush with a paint hopper. By setting a hopper above the brush, the paint in the hopper falls onto the brush by gravity. Although this eliminates the need to repeatedly insert the brush into the paint bucket and improves the efficiency of paint processing, this gravity-based automatic paint application structure cannot be used for painting top surfaces. Therefore, it is still necessary to replace the brush with a regular roller brush, which will still affect the processing efficiency. Utility Model Content

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] Appendix Figure 1-5The paint brush for paint production according to this utility model includes an L-shaped mounting plate 1, a telescopic rod 21 assembly 2 with one end fixedly connected to the middle of the bottom surface of the horizontal end of the mounting plate 1 and capable of quick self-locking, a roller brush 3 with one end rotatably connected to the vertical end of the support plate, located directly above the horizontal end of the mounting plate 1 and parallel to the horizontal end of the mounting plate 1, a paint chamber 4 fixed to the horizontal end of the mounting plate 1 by the support plate, located on one side of the roller brush 3 along its length direction, with one side being arc-shaped and in contact with one side of the roller brush 3, and a long strip discharge port located below the side of the paint chamber 4 that is in contact with the roller brush 3. A filling port 6 with a sealing plug is located in the center of the top surface of the paint tank 4; a stirring and guiding component 7 is rotatably arranged inside the paint tank 4 at the elongated discharge port 5 and placed along the length of the paint tank 4 to guide the paint in the paint tank 4 to the elongated discharge port 5; the roller brush 3 can simultaneously drive the stirring and guiding component 7 to rotate when it rotates; the bottom of the paint tank 4 at the elongated discharge port 5 is inclined; one corner of the top surface of the paint tank 4 away from the roller brush 3 is arc-shaped; the stirring and guiding component 7 includes a rotatably arranged inside the paint tank 4 at the elongated discharge port 5 and one end extending outwards. The paint tank 4 has a drive shaft 71 at one end, multiple stirring blades 72 spaced along the circumference of the drive shaft 71, and a drive belt 73 with one end fitted onto the outer end of the drive shaft 71 and the other end fitted onto the rotating end of the roller brush 3. The telescopic rod assembly 2 includes a telescopic rod 21 connected at one end to the middle of the bottom surface of the horizontal end of the mounting plate 1, a rod sleeve 22 fitted onto the telescopic rod 21, and two sliding grooves 23 located on the top surface of the rod sleeve 22 on both sides of the telescopic rod 21, with both ends penetrating the inner cavity and the outside of the rod sleeve 22. Four limiting grooves 24 are located on the inner walls of both sides of the slide groove 23, with one end of each groove communicating with the inner cavity; two limiting plates 25 are slidably disposed in two slide grooves 23, with one end of each plate used for inserting into the two sides of the telescopic rod 21; four long strip limiting blocks 26 are disposed on both sides of the two limiting plates 25 for sliding in the four limiting grooves 24; several slots 27 are spaced from top to bottom on both sides of the telescopic rod 21 for inserting one end of the two limiting plates 25; and an annular plate 28 is threadedly connected to the rod sleeve 22 at one end of the two limiting plates 25 for limiting the two limiting plates 25.

[0023] Furthermore, each of the two limiting plates 25 is provided with a lever 8 on the top surface of the end away from the telescopic rod 21 to facilitate the movement of the limiting plates 25.

[0024] Furthermore, there is a certain gap between the paint tank 4 and the roller brush, and the gap gradually increases from the elongated discharge port 5 upwards and downwards to prevent the paint from rubbing against the outer shell of the paint tank 4.

[0025] In use: First, pour the paint into the paint tank 4 through the feeding port 6. Then, place the roller brush against the wall. In extreme cases, the rod sleeve 22 is parallel to the vertical wall and perpendicular to the horizontal top surface. At this time, the paint tank 4 is also in a vertical state. The paint in the paint tank 4 flows through the inclined surface at the bottom of the paint tank 4 towards the elongated discharge port 5. Then, cover the rod sleeve 22 and push the telescopic rod 21. The telescopic rod 21 drives the mounting plate 1 to move, and the mounting plate 1 drives the roller brush 3 to move. Then, the roller brush 3 moves while rotating against the surface to be coated. At the same time, the rotating end of the roller brush 3 drives the drive shaft 71 inside the paint tank 4 to rotate through the drive belt 73. The drive shaft 71 drives the agitator. The mixing blade 72 rotates, stirring the paint in the paint hopper 4 towards the elongated outlet 5, allowing the paint to flow quickly towards the outlet 5. However, under normal circumstances, the angle between the roller brush 3 and the wall / ceiling surface is 30°~60° when painting, and the paint hopper 4 is also tilted. The paint in the paint hopper 4 then flows towards the elongated outlet 5 due to gravity. Since one side of the roller brush 3 is in contact with the paint hopper 4, the paint flows from the elongated outlet 5 onto the surface of the roller brush 3. Then, the worker holds the sleeve 22 and pushes the telescopic rod 21. The telescopic rod 21 moves the mounting plate 1, which in turn moves the roller brush 3, causing it to adhere to the surface being painted. While rotating and moving, the rotating end of the roller brush 3 drives the drive shaft 71 inside the paint tank 4 to rotate via the drive belt 73. The drive shaft 71 then drives the stirring blade 72 to rotate, which in turn stirs the paint in the paint tank 4 towards the elongated discharge port 5, allowing the paint to flow quickly towards the elongated discharge port 5. The rounded corner of the paint tank 4 is used to prevent contact with the top surface without significantly affecting the volume of paint in the tank. When the length needs to be adjusted, the annular plate 28 is rotated to move away from the roller brush 3. When the annular plate 28 no longer blocks the opening of the chute 23, the rotation of the annular plate 28 is stopped, and then the lever 8 is moved to move the limiting plate 25 away from the telescopic rod 21. The telescopic rod 21 is moved, and one end of the limiting plate 25 disengages from the slot 27 on one side of the telescopic rod 21, so that the telescopic rod 21 is no longer limited. Then, one end of the telescopic rod 21 is pulled out from the sleeve 22 for a certain length. Then, the lever 8 is turned to move the limiting plate 25 toward the telescopic rod 21, so that one end of the limiting plate 25 is inserted into the slot 27 on one side of the telescopic rod 21, and the telescopic rod 21 is limited. At this time, the other end of the limiting plate 25 slides completely into the groove 23. Then, the annular plate 28 is rotated and moved toward the roller brush 3 until the annular plate 28 covers the groove 23 and stops rotating. Then, the limiting plate 25 is limited and cannot slide. Finally, the sleeve 22 is covered and the roller brush 3 is pushed to apply the coating.

[0026] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
