Description

Technical Field

[0001] This utility model relates to the field of furniture production technology, specifically to a wood veneer paint roller coating device. Background Technology

[0002] Wood veneer is a common decorative material, mainly used in the production of furniture, decorative panels, wooden doors, flooring, etc. Existing wood veneer is formed by combining wood veneer with non-woven fabric. In order to avoid cracking and breakage of the wood veneer during the covering and gluing process, paint needs to be sprayed on the surface of the wood veneer. However, wood veneer itself is a thin sheet material, and when continuous spraying or roller coating is carried out, the wood veneer will warp and affect the surface paint quality. Utility Model Content

[0003] Technical objective: To address the shortcomings of existing wood veneer paint roller coating methods, this utility model discloses a wood veneer paint roller coating device.

[0004] Technical solution: To achieve the above technical objectives, the present invention adopts the following technical solution:

[0005] A wood veneer paint roller coating device includes a wood veneer conveyor line, a paint roller coating mechanism and a UV curing mechanism arranged along the wood veneer conveyor line. The wood veneer conveyor line includes two parallel conveyor belts. An adsorption and fixing mechanism for fixing the wood veneer is arranged below the conveyor belts. Air holes are opened on the conveyor belts to cooperate with the adsorption and fixing end.

[0006] Preferably, the adsorption and fixing mechanism of this utility model includes a vacuum adsorption plate that is lifted and lowered. The vacuum adsorption plate has a hollow structure and is attached to the bottom of the conveyor belt when fixing the wood veneer.

[0007] Preferably, the wood veneer conveying line of this utility model has adjustment components on both sides of the area where the vacuum adsorption plate is located for adjusting the position of the wood veneer. The adjustment components are equipped with push plates that cooperate with the side of the wood veneer. The position of the wood veneer is adjusted by pushing the wood veneer to move through the push plates.

[0008] Preferably, the wood veneer conveying line of this utility model is further provided with a flattening mechanism that slides parallel to the conveying line. The flattening mechanism includes a pressure plate that cooperates with the vacuum adsorption plate. The pressure plate is raised and lowered above the vacuum adsorption plate. A mobile device is connected to the pressure plate to drive the pressure plate to move along the conveying line.

[0009] Preferably, the paint roller coating mechanism of this utility model includes a roller coating roller, which moves on the surface of the wood veneer to apply paint.

[0010] Preferably, the UV curing mechanism of this utility model includes a UV drying chamber and a UV curing lamp. The wood veneer after being painted is fed into the UV drying chamber through the wood veneer conveyor line for irradiation and curing.

[0011] Beneficial effects: The wood veneer paint roller coating device disclosed in this utility model has the following beneficial effects:

[0012] 1. This utility model provides an adsorption and fixing mechanism below the conveyor belt, which can keep the wood veneer adhered to the surface of the conveyor belt during roller coating, thereby ensuring the uniformity of the paint on the surface of the wood veneer and reducing the impact of wood veneer warping.

[0013] 2. This utility model has adjustment components on the left and right sides of the wood veneer conveyor line. By pushing the side of the wood veneer with a push plate, the wood veneer can be kept in the same position on the conveyor line when the paint is rolled, which reduces the difficulty of the rolling operation.

[0014] 3. This utility model sets a pressure plate above the conveyor line. When the wood veneer is adsorbed and fixed, the pressure plate can ensure that the wood veneer is flat, and then increase the vacuum adsorption force to further ensure the flatness of the wood veneer surface.

[0020] Reference will now be made in detail to embodiments of the present disclosure, one or more of which are set forth herein. Each embodiment and example is provided by way of explanation of the apparatus, composition, and materials of the present disclosure, and not by way of limitation. Rather, the following description provides convenient illustrations for implementing exemplary embodiments of the present disclosure. Indeed, it will be apparent to those skilled in the art that various modifications and variations can be made to the teachings of the present disclosure without departing from the scope or spirit of the present disclosure.

[0021] like Figures 1-3 As shown, this utility model discloses a wood veneer paint roller coating device, including a wood veneer conveyor line 1, and a paint roller coating mechanism 2 and a UV curing mechanism 3 arranged along the wood veneer conveyor line 1. The paint roller coating mechanism includes a roller coating roller 7, which moves on the surface of the wood veneer to apply paint. The UV curing mechanism includes a UV drying chamber 8 and a UV curing lamp 9. The wood veneer after being coated with paint is sent into the UV drying chamber 8 through the wood veneer conveyor line for irradiation and curing. Both the paint roller coating mechanism and the UV curing mechanism can directly utilize existing mature roller coating and curing equipment without affecting the implementation of this utility model. The wood veneer conveyor line 1 includes two parallel conveyor belts 4. An adsorption and fixing mechanism for fixing the wood veneer is provided below the conveyor belts 4. Air holes 10 are opened on the conveyor belts 4 to cooperate with the adsorption and fixing end.

[0022] This invention utilizes an adsorption and fixing mechanism to adsorb and fix the wood veneer through the air holes on the conveyor belt 4, thereby ensuring the stability of the wood veneer during the paint roller coating process and keeping it tightly attached to the conveyor belt 4. In this embodiment, the adsorption and fixing mechanism includes a vacuum adsorption plate 5 with a lifting mechanism, which is driven to lift and lower via a lifting cylinder or similar device. The vacuum adsorption plate 5 has a hollow structure and is positioned below the conveyor belt 4 during wood veneer fixing. The vacuum adsorption plate 5 has openings corresponding to the areas of the air holes on the conveyor belt 4, allowing the vacuum adsorption plate 5 to be connected to a vacuum adsorption device, such as a vacuum pump, via a flexible hose. The suction generated at the openings on the vacuum adsorption plate 5 can adsorb and fix the wood veneer onto the conveyor belt 4. Preferably, the length of the vacuum adsorption plate 5 is matched to the length of the roller coating. During the paint roller coating process, the vacuum adsorption plate 5 provides support, ensuring the paint coating effect.

[0023] Furthermore, the wood veneer conveying line 1 of this utility model is equipped with adjustment components on both sides of the area where the vacuum adsorption plate 5 is located for adjusting the position of the wood veneer. The adjustment components are equipped with push plates 11 that cooperate with the side of the wood veneer. The position of the wood veneer is adjusted by pushing the wood veneer to move by the push plates 11. The push plates 11 are driven to move by pushing devices such as electric push rods or cylinders that are perpendicular to the plate surface, so that the push plates 11 move in a direction perpendicular to the conveying line, thereby adjusting the position of the wood veneer on the conveying line. This ensures that the position of the wood veneer is uniform each time it is coated, reduces the operation difficulty of the paint coating mechanism, and avoids frequent adjustments.

[0024] In the case of roll coating, the wood veneer may warp due to the previous winding on the roll, making it impossible for a single adsorption and fixing mechanism to guarantee the adhesion of each area. Therefore, the wood veneer conveyor line 1 of this utility model is also equipped with a flattening mechanism that slides parallel to the conveyor line. The flattening mechanism includes a pressure plate 6 that cooperates with the vacuum adsorption plate 5. The pressure plate 6 is raised and lowered above the vacuum adsorption plate 5. A mobile device is connected to the pressure plate 6 to drive the pressure plate 6 to move along the conveyor line. The mobile device can be a robotic arm or other multi-degree-of-freedom mechanism that can drive the pressure plate to move downward and horizontally.

[0025] In use, the wood veneer can be placed on the wood veneer conveyor line 1 of this invention by manual feeding or roll feeding, depending on the specific production scenario requirements. The wood veneer is transported by the conveyor belt 4. When the wood veneer moves to the area of ​​the paint roller coating mechanism, the vacuum adsorption plate 5 moves up to below the conveyor belt 4 to fix the wood veneer by vacuum adsorption. The pressure plate 6 flattens and smooths the surface of the wood veneer, so that the wood veneer can be flatly attached to the surface of the conveyor belt 4. Then, the paint roller coating is performed on the surface of the wood veneer. After the paint roller coating is completed, the vacuum adsorption is canceled, and the wood veneer is transported to the UV curing mechanism 3 by the conveyor belt 4 for curing, finally forming the finished painted wood veneer product.
