Description

Technical Field

[0001] This utility model belongs to the field of timber transportation technology, and specifically relates to a veneer grading and conveying device. Background Technology

[0002] Wood veneer is a commonly used material in furniture manufacturing and interior decoration, and its quality grading has a significant impact on the final product quality. Accurate and efficient grading and conveying of wood veneer not only improves production efficiency but also ensures consistent product quality. Currently, the common method in wood veneer grading and conveying is to use a lifting conveyor belt to achieve grading and transfer. However, this method has significant drawbacks. Lifting the entire conveyor belt places a huge load, increasing energy consumption and accelerating wear on equipment components due to prolonged heavy loads, shortening equipment lifespan. It also leads to misalignment and accumulation of wood veneer during grading and conveying, further affecting grading effectiveness and production efficiency. Utility Model Content

The rear part of the grading transition plate 28 can be operated to flip to the lower conveying channel 27 and the lower side of the second conveying roller 22, ensuring that the veneer can fall accurately into the designated position. The operation is stable and maintenance is convenient. After the grading adjustment drive device 29 drives the grading transition plate 28 to flip to the lower side of the second conveying roller 22, the veneer moves backward and downward and falls. After the grading adjustment drive device 29 drives the grading transition plate 28 to flip to the lower conveying channel 27, the veneer is clamped to the lower conveying channel 27 and continues to be clamped backward, completing the automatic grading and transfer process. The overall load is low and the operation is efficient.

[0017] Specifically, the graded adjustment drive device 29 includes a graded drive motor, a first swing transmission rod 210, and a second swing transmission rod 211. The output end of the graded adjustment drive device 29 is fixedly connected to the first swing transmission rod 210, the first swing transmission rod 210 is hinged to the second swing transmission rod 211, and the lower end of the second swing transmission rod 211 is hinged to the middle of the graded transition plate 28, providing stable power transmission and precise control. It has a compact structure and is easy to maintain. Adjusting the conveying speed and the position of the graded transition plate can achieve two transition methods: the graded transition plate can be supported by its upper end face or limited and guided by its lower end face.

[0018] Specifically, high-pixel cameras can be installed on the upper front and lower front sides of the grading transition plate 28 on the frame. Defect identification and grading are performed in conjunction with existing mature vision systems. The grading drive motor is driven and controlled according to the grading results. Actual grading processing is carried out through the grading adjustment drive device 29. The present invention aims to provide a grading conveying mechanical structure. The identification process is not the focus of this solution, and the vision solution is a conventional technology, so it will not be described in detail.

[0019] Specifically, a grading collection component 3 for collecting graded veneer is provided on the lower side of the grading component 2. The grading collection component 3 includes a first flip plate 31 and a second flip plate 32 arranged symmetrically on the left and right, and a grading collection drive device 33 for driving the first flip plate 31 and the second flip plate 32 to rotate. The rotation axes of the first flip plate 31 and the second flip plate 32 are parallel to the front and back directions, realizing symmetrical collection and stable stacking of veneer. The design is simple and highly reliable.

[0020] Specifically, the cross-sections of the first flip plate 31 and the second flip plate 32 are cross-shaped, which enhances the structural rigidity and improves the flipping efficiency, with lower load and stronger durability.

[0021] Specifically, the graded collection drive device 33 includes a graded collection motor, and a collection transmission rod 34, a first flipping rod 36, and a second flipping rod 37 rotatably connected to the mounting base 1. The graded collection motor is driven and connected to the collection transmission rod 34 through a spur gear pair 35. The first flipping plate 31 is fixed on the first flipping rod 36, and the second flipping plate 32 is fixed on the second flipping rod 37.

The slapping device 4 includes a slapping cylinder 41 and a slapping plate 42. The output end of the slapping cylinder 41 faces the first flip plate 31 and the second flip plate 32 and is connected to the slapping plate 42. It automatically sorts the edges of the wood veneer, ensuring that the stacking is neat. The structure is simple and the load is low.

[0023] Specifically, the mounting base 1 has three graded components 2 arranged at intervals, supporting four-level classification to meet different quality requirements, with strong expandability and convenient maintenance.

[0024] Specifically, a grading guide plate 6 is installed on the rear side of the last grading component 2 via a side bracket 5. The grading guide plate 6 is located on the rear side of its lower conveying channel 27 and is inclined to the rear and lower side to guide the veneer to slide smoothly, reduce jamming, ensure high reliability, and is easy to install.

[0025] Specifically, a graded collection component 3 is provided on the lower side of the graded guide plate 6, which facilitates centralized processing of the final product, optimizes the structure, and reduces the load.

[0026] Specifically, the lower side of the grading and collection component 3 is provided with a side conveyor belt 7 for moving the graded veneer to the left or right. A aligning device 4 is also provided on one side of the side conveyor belt 7, which facilitates the rapid transfer and subsequent processing of the veneer, and is efficient in operation and easy to maintain.

[0027] Working process description: Wood veneer enters from the front of the device and is conveyed by the first belt 25 and the second belt 26. The grading adjustment drive device 29 controls the grading transition plate 28 to flip according to the grading requirements. The whole process is simple in structure and highly reliable. When the grading transition plate 28 turns to the underside of the second conveyor roller 22, the wood veneer falls downward to the grading collection component 3, achieving primary classification. The load is low and maintenance is convenient. When the grading transition plate 28 turns to the lower conveying channel 27, the wood veneer is continued to be conveyed to the second grading component 2 for secondary grading, and then enters the third grading component 2 for tertiary grading. Finally, after being guided down by the grading guide plate 6, it can be graded into four levels. The device operates smoothly. The graded wood veneer is collected by the flipping plate, and the aligning device 4 makes the wood veneer stacked neatly. Finally, it is removed by the side conveyor belt 7, completing the entire grading and conveying process. The overall design is optimized, easy to maintain, and highly efficient.
