Description

Technical Field

[0001] This utility model relates to the field of roller coating equipment technology, and specifically to a roller coating equipment for floor paint. Background Technology

[0002] Applying paint to floor surfaces provides excellent protection and decoration, improving wear resistance, water and moisture resistance, and corrosion resistance. It also enriches the floor's color options and enhances its gloss and aesthetics. One method of painting floor surfaces is using a roller coating device. The coating roller in this device can be raised and lowered as needed to accommodate flooring of different thicknesses. Simultaneously, a steel roller located on one side of the coating roller can also be raised and lowered. However, in existing roller coating devices, the coating roller and steel roller are raised and lowered separately, which can easily lead to height differences, affecting the accuracy of adjusting their spacing. Therefore, this invention provides a floor paint roller coating device. Utility Model Content

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] like Figure 1 and Figure 2As shown, a floor paint roller coating device includes: a frame 1, on which a conveyor belt 2 and two supports 3 are mounted, one on each side of the conveyor belt 2. The conveyor belt 2 is driven by a fourth drive motor 20 mounted on the frame 1, which can move the floor. The supports 3 have a rectangular column structure and are hollow inside.

[0021] A coating roller 4 and a steel roller 5 are arranged parallel to each other between the two supports 3.

[0022] like Figure 3 and Figure 4 As shown, the two ends of the shaft of the coating roller 4 extend into the two brackets 3 and are connected to the sliding block 6 set inside the bracket 3. One end of the shaft of the coating roller 4 is connected to the first drive motor 7 set on the sliding block 6 and is driven to rotate by the first drive motor 7.

[0023] The two ends of the steel roller 5 shaft extend into the two supports 3, and sliders 8 are provided at both ends. The sliders 8 slide in the sliding grooves 9 opened on the sliding blocks 6. A first lead screw 10 is provided in the sliding grooves 9. The first lead screw 10 is threadedly engaged with the slider 8, and one end of the first lead screw 10 is connected to a second drive motor 11 located at the end of the sliding block 6. The second drive motor 11 drives the first lead screw 10 to rotate, and the first lead screw 10 drives the slider 8 to slide in the sliding grooves 9.

[0024] The diameter of the coating roller 4 is larger than that of the steel roller 5. The coating roller 4 is used to apply paint, and its bottom end needs to contact the top surface of the floor. The steel roller 5 is used to keep the paint on the surface of the coating roller 4 flat and uniform. Its bottom does not need to contact the floor, and it is best to keep a distance from the floor to avoid mutual interference.

[0025] The sliding block 6 is slidably fitted at both ends onto the slide rail 12 inside the bracket 3, and the first side of the sliding block 6 is provided with two connecting parts 13 respectively near its two ends. The connecting parts 13 are threadedly engaged with the second lead screw 14 inside the bracket 3, and the top of the second lead screw 14 is connected to the third drive motor 15 located at the top of the bracket 3. The third drive motor 15 drives the second lead screw 14 to rotate, and the second lead screw 14 drives the sliding block 6 to rise and fall along the slide rail 12.

[0026] One of the connecting parts 13 has an extension part 16 connected to its side, extending to the outside of the bracket 3. A dust suction hood 17 is provided between the two extension parts 16. The dust suction hood 17 has an open bottom and a corrugated telescopic tube 18 connected to its top. The top of the corrugated telescopic tube 18 is fixed to a support frame 19 located on the side of the bracket 3, and its top is connected to an external vacuuming device. The dust suction hood 17 is used to suck out dust and other impurities from the floor surface to improve the paint coating effect. At the same time, the dust suction hood 17 can be raised and lowered synchronously with the sliding block 6 to adapt to floor thicknesses. Preferably, the bottom of the dust suction hood 17 has a flared structure to improve the dust suction effect.

[0027] Working process: The floorboards are placed on conveyor belt 2 and conveyed sequentially through dust hood 17 and coating roller 4. Dust hood 17 removes dust from the floorboard surface, while coating roller 4 applies paint to the floorboard surface. The top of coating roller 4 receives the paint, which is then smoothed by steel roller 5 and applied from the bottom. Steel roller 5 can move under the action of the first screw 10 to change the distance between it and coating roller 4, thereby adjusting the paint thickness. Driven by the second screw 14, coating roller 4, steel roller 5, and dust hood 17 can be raised and lowered to accommodate floorboards of different thicknesses.

[0028] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
