When the coating wheel becomes stiff after multiple rolling brushing, the device can only be discarded and the bracket cannot be reused. In addition, when rolling brushing, the coating wheel needs to be soaked in paint multiple times, which will cause different thicknesses in adjacent areas. It is impossible to continuously feed automatically and carry out uninterrupted painting over a large area. Utility Model Content

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.
[0022] like Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, a fire retardant paint automatic feeding brushing device includes a brush frame 1, a brush wheel 9 and a pressure plate 15, side frames 2 are provided at both ends of the brush frame 1, a paint box placement frame 4 is fixed at the upper end between the side frames 2, a drainage hole 7 is provided at the center position of the paint box placement frame 4, a paint box 17 is placed inside the paint box placement frame 4, and limiting holes 5 are provided at both ends of the paint box placement frame 4. A detachable roller 8 is installed on the side frame 2, and the brush wheel 9 is installed between two groups of rollers 8. A first cone wheel 11 is fixed on the roller 8. Threaded holes 16 are provided at both ends of the pressure plate 15. The first cone wheel 11 is meshedly connected with a second cone wheel 14, and a screw rod 13 is fixed at the center position of one end of the second cone wheel 14. One end of the screw rod 13 passes through the paint box placement frame 4 and is connected to the pressure plate 15.
[0023] like Figure 2 as well as Figure 3 As shown, a clamping block 12 is installed at the notch of the side frame 2, and the side frame 2 and the clamping block 12 are connected by bolts. The side frame 2 and the clamping block 12 are spliced to form a clamping slot 6, and a roller 8 is installed inside the clamping slot 6. A rectangular groove is opened inside one end of the roller 8, and rectangular connecting shafts 10 are provided at both ends of the brush wheel 9. The connecting shaft 10 is located inside the groove, and the brush wheel 9 and the roller 8 form a clamping structure.
[0024] Exemplarily, the side frame 2 and the block 12 are used as detachable structures, and the block 12 can be disassembled, so that the roller 8 can be removed from the inside of the slot 6, and the brush wheel 9 can be removed from the side frame 2, and the brush wheel 9 can be replaced. Rectangular shapes are provided at both ends of the brush wheel 9, and other shapes can also be used as long as the internal structure of the roller 8 does not rotate relative to each other, so that the roller 8 can be driven synchronously when the brush wheel 9 rolls.
[0025] like Figure 2 as well as Figure 3 As shown, a circle of concave grooves is provided on the screw rod 13, and a snap ring is installed inside the concave groove. The snap ring is located inside the paint box placement rack 4, and the size of the snap ring is larger than the size of the limiting hole 5. The paint box placement rack 4 and the screw rod 13 constitute a rotating structure. The screw rod 13 and the second cone wheel 14 are an integrated structure, and a thread is provided at the position of the upper half of the second cone wheel 14. A limiting groove 3 is provided at the center position of the upper end of the adjacent side of the side frame 2, and protrusions are provided at both ends of the pressure plate 15. The cross section of the protrusion is the same as the cross section of the limiting groove 3, and the side frame 2 and the pressure plate 15 constitute a sliding structure. Threaded holes 16 are provided at both ends of the pressure plate 15, and the screw rod 13 is connected inside the threaded hole 16.
[0026] Exemplarily, by passing the screw rod 13 through the limiting hole 5 and rotating the screw rod 13, the two groups of screw rods 13 are respectively connected to the threaded holes 16 opened on the pressure plate 15. After the screw rod 13 and the pressure plate 15 are initially connected, the retaining ring is installed using the recessed groove opened on the screw rod 13. Here, the size of the retaining ring is larger than the size of the limiting hole 5. Then, under the action of the retaining ring, the screw rod 13 will not fall, so that the height of the second cone wheel 14 fixed at one end of the screw rod 13 is fixed. When the protrusions at both ends of the pressure plate 15 fall into the limiting groove 3, the second cone wheel 14 is rotated to rotate the screw rod 13 fixed at one end of the second cone wheel 14. When the two groups of screw rods 13 rotate synchronously, the pressure plate 15 can only move up and down because the movement trajectory of the pressure plate 15 is limited.
[0027] like Figure 4 As shown, the lower end of the coating box 17 is provided with multiple discharge nozzles, each set of discharge nozzles are installed inside the discharge hole 7, and the upper movable seal of the coating box 17 is connected with a sealing cover 18, and the sealing cover 18 is located at the lower end of the pressure plate 15.
[0028] Exemplarily, the paint box 17 is installed inside the paint box placement rack 4, and the multiple drainage nozzles provided on the paint box 17 are all installed inside the drainage hole 7. When the pressure plate 15 moves downward, it will press the sealing cover 18, so that the paint inside the paint box 17 is sprayed out through the drainage nozzle through the drainage hole 7 and falls onto the brush wheel 9, thereby realizing automatic feeding to the brush wheel 9.
[0029] Working principle: When the device is used to apply fire retardant paint, the brush holder 1 is held and pushed to make the brush wheel 9 roll on the surface of the object to be painted. When the brush wheel 9 rotates, it will drive the roller 8 to rotate inside the slot 6. Since the first cone wheel 11 is fixed to the outside of the roller 8, the first cone wheel 11 will rotate synchronously. The second cone wheel 14 is driven to rotate by the first cone wheel 11. At the same time, the screw 13 fixed at one end of the second cone wheel 14 rotates. When the two sets of screws 13 rotate synchronously, the protrusions at both ends of the pressure plate 15 fall into the inside of the limiting groove 3, and the movement trajectory of the pressure plate 15 is limited, so that the pressure plate 15 can only It can move up and down. When the pressure plate 15 moves downward, it will press the sealing cover 18, so that the paint inside the paint box 17 will be sprayed out through the discharge nozzle and the discharge hole 7 and fall onto the brush wheel 9, thereby realizing automatic feeding to the brush wheel 9 and completing the step of automatic feeding while brushing. When the brush wheel 9 needs to be replaced, the block 12 can be disassembled, so that the roller 8 can be removed from the inside of the slot 6, and then the brush wheel 9 can be removed from the side frame 2, and then the connecting shafts 10 at both ends of the brush wheel 9 are removed from the inside of the roller 8, and a new brush wheel 9 is installed, thereby realizing the replacement of the brush wheel 9.
