Description

Technical Field

[0001] This application relates to the technical field of floor coating equipment, and in particular to a floor beveling and coating equipment. Background Technology

[0002] The surface and sides of the wooden floorboards are transitioned by a chamfer, which has an angle of 30-60° compared to the surface. The chamfer is achieved through milling during the tongue-and-groove machining process.

[0003] Traditionally, after tongue and groove processing of the flooring, the surface is coated. However, this process often causes paint to accumulate at the edges (beveled corners) of the flooring, commonly known as the "frame effect".

[0004] Therefore, existing technology uses a process of first applying surface coating and then machining the tongue and groove. However, in this process, the paint at the edges is milled away during the chamfering process, requiring manual application of paint to the chamfered areas, which is labor-intensive and has low production efficiency. Utility Model Content

[0005] The first technical objective of this application is to provide a floor beveling and painting device that can perform online painting of floor beveling areas. The assembly line production reduces the workload of workers and improves production efficiency. The specific technical solution adopted is as follows:

Detailed Implementation

[0026] The technical solutions in this application are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] Example

[0028] Reference Figure 1 The floor beveling and painting equipment shown includes a conveying mechanism 10, a roller coating mechanism 20, and a movable support 30.

[0029] The conveying mechanism 10 is capable of conveying along the x-axis direction and can be any type of existing technology. Preferably, the conveying mechanism 10 is a narrow belt conveyor with anti-slip grooves on the belt surface and is equipped with an upper pressure roller unit to ensure smooth floor conveying and reduce the impact of the processing of the roller coating mechanism 20 on the floor conveying.

[0030] The roller coating mechanism 20 includes a bracket 21 mounted on the frame of the conveying mechanism 10, a roller 22 mounted on the bracket 21, and a paint supply unit 23 capable of supplying paint to the roller 22. In this embodiment, the bracket 21 is mounted on the frame of the conveying mechanism 10 via an adjustment unit 24.

[0031] The bracket 21 is a metal frame that provides support and space for the installation of the roller 22. In this embodiment, the bracket 21 is a roller seat, on which the roller 22 is rotatably mounted via an axle. After installation, the axle of the roller 22 is perpendicular to the x-axis and has an inclination angle of 30-60° with the conveying surface of the conveying mechanism 10. The inclination angle between the axle of the roller 22 and the conveying surface of the conveying mechanism 10 depends on the chamfer angle of the floor to be painted. Generally, the angle between the chamfer and the floor surface is 45°. In this case, the axle of the roller 22 forms a 45° inclination angle with the conveying surface of the conveying mechanism 10, so that the outer rim surface of the roller 22 can adhere to the chamfer surface to complete the roller coating process. Similarly, if the angle between the chamfer and the floor surface is 30°, then the axle of the roller 22 should form a 30° inclination angle with the conveying surface of the conveying mechanism 10.

[0032] Preferably, the roller coating mechanism 20 further includes an adjustment unit 24, which is used to adjust the setting position of the roller 22 in the y-axis direction and z-axis direction, as well as its tilt angle relative to the conveying surface.

[0033] The adjustment unit 24 can be of the prior art, such as a combination of a cylinder that can extend and retract along the z-axis and a cylinder that can extend and retract along the y-axis, and the setting position of the roller 22 is adjusted by the bracket 21.

[0034] In this embodiment, the adjustment unit 24 includes a cylinder 241 and an adjustment rod 242 pivotally connected to the telescopic end of the cylinder 241. The adjustment rod 242 is a hollow rod with an adjustment groove 243 at its end. A movable rod 244 extends into the adjustment rod 242. A bolt passes through the adjustment groove 243 and the screw hole on the movable rod 244, and fixes the position of the movable rod 244 by cooperating with a nut. Meanwhile, the other end of the movable rod 244 is welded and fixed to the bracket 21.

[0035] The adjusting rod 242 is perpendicular to the axle of the roller 22, so that the tilt angle of the roller 22 can be adjusted by changing the angle between the adjusting rod 242 and the column 241. The column 241 and the adjusting rod 242 are pivotally connected by bolts. The angle can be adjusted by loosening the nut and fixed by tightening the nut.

[0036] To avoid obstructing the location of the paint recycling tank 40, the adjusting rod 242 is fixedly connected to the telescopic end of the cylinder 241 via a connecting rod 245 arranged along the x-axis. Specifically, one end of the connecting rod 245 is connected to the adjusting rod 242 via a pivot seat 246, and the other end is fixedly connected to the telescopic end of the cylinder 241 via a mounting seat 247. Alternatively, it can be directly welded or screwed to the telescopic end of the cylinder 241. Through this structural adjustment, the roller 22 is located to the side of the adjusting unit 24 along the x-axis.

[0037] The paint supply unit 23 includes an oil nozzle mounted via a bracket 21. The oil nozzle is located above the roller 22 and faces the outer rim surface of the roller 22, and is connected to an external paint source. Preferably, the oil nozzle is a tube of sufficient strength, such as a metal tube, extending into the bracket 21 through an opening with its opening positioned above the roller 22, and is fixed to the bracket 21 by screws or other means. The oil nozzle is connected to a paint bucket via an oil pipe, valve, and pump, thereby enabling the supply of paint to the outer rim surface of the roller 22. Paint is applied to the chamfered surface of the floor as the outer rim surface of the roller 22 rolls into contact with it.

[0038] Preferably, the painting equipment also includes a paint recovery tank 40 disposed below the roller 22. Excess paint flows into the paint recovery tank 40, and when it is full, it is poured into a paint bucket for reuse. Specifically, an oil guiding slope is provided below the roller 22, and the end of the oil guiding slope is connected to the recovery tank (not shown in the figure).

[0039] The movable support 30 includes a fixed base 31, a telescopic unit 32, and a support 33. The fixed base 31 is screwed onto the frame of the conveying mechanism 10, located on the conveying surface of the conveying mechanism 10 opposite to the roller coating mechanism 20. The telescopic unit 32 can be any of the prior art, such as a telescopic cylinder. A simpler structure includes a pair of grooves along the y-axis formed on the fixed base 31, a connecting rod with a threaded hole at one end, a screw, and a nut assembly. The screw passes through the threaded hole and the grooves, and the relative position of the telescopic unit 32 and the fixed base 31 can be fixed by tightening the nut. The support 33 is arranged along the x-axis, and its back is screwed or welded to the other end of the telescopic unit 32, so that the movable support 30 can move closer to or further away from the roller coating mechanism 20 along the y-axis.

[0040] With the above structure, by adjusting the position of the movable support 30 in the y-axis direction, when the floor is conveyed to the roller coating mechanism 20 by the conveyor mechanism 10 under the limitation of the movable support 30, the chamfer of the floor contacts the surface of the outer rim of the roller 22, and the paint is applied to the chamfer as the outer rim of the roller 22 rolls against the chamfer surface of the floor. This allows for online painting of the floor chamfer, and assembly line production can reduce the workload of workers and improve production efficiency.

[0041] Preferably, the roller 22 is a steel roller with a cylindrical shape. This gives the roller 22 a certain rigidity, thereby ensuring the amount of paint applied and preventing the formation of a rimmed effect.

[0042] In addition, the outer rim surface of roller 22 has raised textures, such as diagonal lines, with an arbitrary tilt angle, but the height of the raised textures should not exceed 0.1 mm. This allows the outer rim surface of roller 22 to carry an appropriate amount of paint, ensuring full paint coverage at the chamfer while avoiding the occurrence of a rimming effect.

[0043] More importantly, the painting equipment also includes an air blowing mechanism 50 located after the roller coating mechanism 20. Specifically, the air blowing mechanism 50 includes an air pipe 51 connected to an external air source and an air nozzle 52 connected to the air pipe 51. The air nozzle 52 blows air from the movable support 30 side toward the side where the roller coating mechanism 20 is located, and the axial direction of the air nozzle 52 has an inclination angle of 30 to 60° with the conveying surface. In this embodiment, the air pipe 51 is fixed to the front of the roller 22 in the x-axis direction by a mounting base 246.

[0044] The air tube 51 can be a flexible tube, and the position and tilt angle of the air nozzle 52 can be fixed by a bracket or other structure. For the sake of structural simplicity, a metal corrugated tube is preferred as the air tube 51, so that the position and tilt angle of the air nozzle 52 can be adjusted by bending the air tube 51.

[0045] The tilt angle of the air nozzle 52 does not need to be consistent with the chamfer of the floor or the tilt angle of the roller 22; it only needs to be approximately within the range of 30 to 60 degrees.

[0046] An external air source can be an air compressor.

[0047] By using the air blowing mechanism 50, the paint on the chamfered surface can be evenly leveled and dried quickly through air blowing. Blowing air from the side of the movable support 30 towards the side where the roller coating mechanism 20 is located avoids paint contamination of the floor surface at the chamfered edge and facilitates the recovery of excess paint.

[0048] The above describes the form of a single-sided roller coating mechanism 20. By simply repeating the above structure on the opposite side, the process requirements for chamfering and painting on both sides can be met.

[0049] The painting equipment in this embodiment can be controlled by a PLC control system, or connected to the production line and controlled by the PLC control cabinet of the main production line.

[0050] In this embodiment, the x-axis, y-axis, and z-axis are perpendicular to each other.

[0051] The method of using the floor beveling and painting equipment provided in this embodiment is as follows:

[0052] The chamfered surface is coated with paint using a steel roller 22 with its rim parallel to the chamfered surface, and the paint is leveled and dried by blowing air.

[0053] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this application.
