Description

Technical Field

[0001] The invention relates to the technical field of spraying equipment, in particular to a multi-surface spraying machine for surface treatment of furniture wood boards. Background Art

[0002] Wood boards are commonly used materials in furniture making. Different types of wood boards vary in performance, price and environmental friendliness.

[0003] The processing of furniture wood panels involves multiple steps, from raw material processing to finished product assembly. The processing procedures for different types of wood (such as solid wood, plywood, and MDF) vary. The main processes for furniture wood panel processing include raw material processing, cutting and slitting, planing and sanding, splicing and gluing, edge banding, surface finishing, drilling and grooving, etc. Surface finishing specifically encompasses various processes, including veneer, paint spraying, lamination / UV curing, and more. Paint spraying is crucial for enhancing aesthetics and protecting the material, and is the most commonly used surface treatment.

[0004] However, due to technical defects, traditional furniture wood boards often have the following technical bottlenecks and requirements when undergoing automated spraying production:

[0005] 1. Manual dependence and efficiency bottleneck: Traditional wood panel spraying mostly uses manual segmentation operations or semi-automatic equipment, which has problems such as low manual positioning accuracy, cumbersome flipping process, and inconsistent process connection, resulting in low production efficiency and difficulty in adapting to mass production needs.

[0006] 2. Spraying quality and material waste: Existing equipment lacks accurate positioning for stacked wood boards, which can easily lead to spray obstruction and uneven paint surfaces. Furthermore, the single-board spraying process results in low paint utilization (especially for thin wood boards), high paint consumption costs, and significant drying energy and time costs.

[0007] 3. Limitations of single equipment functions: Most of the equipment on the market is designed for fixed-specification wood boards, lacks multi-degree-of-freedom adjustment capabilities, and is difficult to accommodate the processing needs of wood boards of different thicknesses and sizes. The clamping mechanism and the spray path are prone to interference.

[0008] 4. Production safety and environmental hazards: Manual intervention in handling, flipping and other links poses a risk of mechanical injury; open spraying operations lead to paint mist diffusion and pollution; traditional hot air drying systems have low thermal energy utilization and pose safety hazards.

[0009] 5. Insufficient process coordination: The equipment in each process of the existing production line operates independently, and the flow of materials relies on intermittent operations, resulting in mismatched production rhythms and high equipment vacancy rates, making it difficult to achieve continuous operation of the entire process.

[0010] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Summary of the Invention

[0011] In response to the defects in the existing technology, the present invention provides a multi-surface spray machine for the surface treatment of furniture wood boards, which is used to solve the problems of traditional technology in the process of surface spraying of furniture wood boards, such as manual dependence and low production efficiency, unstable spraying quality and serious material waste, single equipment function and insufficient flexibility, and poor process coordination.

[0039] Compared with the prior art, the present invention has the following beneficial effects:

[0040] 1. Efficient automation and process integration: Through the coordinated control of components such as the lifting and telescopic cylinder, stepper motor, pusher mechanism, and steering disc, the entire process of automatic material connection, positioning, flipping, spraying, and conveying of stacked wood boards is automated, significantly reducing manual intervention and improving production efficiency. The use of multi-degree-of-freedom mechanical structures (such as U-shaped swing arms, L-shaped swing arms, and square flip frames) combined with programmed control completes the multi-task connection of clamping, surface changing, spraying, and drying, ensuring the consistency and efficiency of the production process.

[0041] 2. Precise positioning and optimized spraying quality: The combined action of the telescopic push cylinder and the steering disc enables precise centering and multi-angle positioning of the stacked wood panels, ensuring that the spraying surface is fully exposed and unobstructed, avoiding blind spots. The side spraying seat and the booster spray head spray in stages (side spraying and surface spraying), combined with the hot air drying system, ensure uniform paint coverage and rapid curing, reducing paint dripping or accumulation.

[0042] 3. Resource conservation and cost control: The centralized spraying technology for the ends of stacked wood boards avoids the waste of paint spraying on individual boards piece by piece. It is especially suitable for thin wood boards and significantly reduces the paint consumption per unit product.

[0043] The drying system and the spraying process operate alternately, using hot air circulation to accelerate drying, shorten production cycles and reduce energy consumption.

[0044] 4. Adaptability and flexibility to multiple working conditions: Through the clamping switching of the U-shaped swing arm and the L-shaped swing arm and the 90° rotation of the square flip frame, it can adapt to the clamping requirements of wooden boards of different sizes and thicknesses, avoiding the interference problem between the spraying position and the clamping position, and supports multi-angle spraying (four-sided end faces and double surfaces); the staggered pushing mechanism (the lifting and lowering material support plate rises by the thickness of one wooden board at a time) ensures stable separation and precise positioning of wooden boards during continuous operation, adapting to the needs of mass production.

[0045] 5. Improved safety and stability: Mechanical clamping replaces manual handling, reducing operational risks; hydraulic and electronic drive systems ensure controllable clamping force to avoid damage to the wood boards; spraying and drying processes are completed in a closed environment, reducing paint mist diffusion and heat loss, and improving the working environment.
