A group of veneers are usually assembled and glued together in the direction of the wood grain of adjacent layers, and the surface board and the inner layer board are usually symmetrically arranged on both sides of the center layer or the core of the board. The inner layer board is also called the wood board substrate. The veneers coated with glue are staggered in the direction of the wood grain to form a slab, which is pressed under heating conditions. The physical and mechanical properties in the vertical and horizontal directions are slightly different. Commonly used are three-ply board and five-ply board. Plywood can improve the utilization rate of wood and is a major way to save wood.

[0023] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0024] like Figure 1 , Figure 2 and Figure 4 As shown, the utility model provides a plastering device for producing a wood board substrate, comprising a conveying roller 100, a detection component 200 and a plastering component 300. The detection component 200 is installed on the conveying roller 100. The detection component 200 has a detection end for detecting defects on the wood board substrate N. The plastering component 300 comprises a plurality of nozzles 310 fixed above the conveying roller 100, a plurality of feed pipes 320 and a plurality of valves 330. The plurality of nozzles 310 are arranged in sequence along a horizontal direction perpendicular to the conveying roller 100. Discharge ports are formed at the bottom of the plurality of nozzles 310. The tops of the plurality of nozzles 310 are respectively connected to external materials via a plurality of feed pipes 320. The plurality of valves 330 are respectively installed on the plurality of feed pipes 320 for adjusting the material flow rate in the feed pipes 320 according to the surface condition of the part directly facing the wood board.

[0025] During implementation, the location of the defect on the wooden board substrate N can be known according to the detection component 200. When the wooden board substrate N passes through the plastering component 300, the multiple nozzles 310 in the plastering component 300 spray putty to the surface of the wooden board substrate N. When the defect on the rice board substrate is facing one of the nozzles 310, the valve 330 can be controlled to increase the material flow in the feed pipe 320 to spray more putty to fill the defect. The surface of the wooden board substrate N is evenly scraped, replacing manual filling, facilitating subsequent plastering work, and improving production efficiency.

[0026] It is understandable that the above defects refer to the scars, holes and gaps left over from the previous process on the wood substrate N, which require more putty to fill than other parts. Therefore, when the wood board passes through the nozzle 310, the nozzle 310 needs to spray more putty on the defective part of the wood substrate N below it to ensure that the surface of the wood substrate N is smooth after subsequent plastering.

[0027] The conveying roller 100 in this embodiment is a structure for conveying the wooden board substrate N, so that the wooden board substrate N to be plastered passes through the detection component 200 and the plastering component 300 .

[0028] In one embodiment, the detection assembly 200 and the plaster scraping assembly 300 are sequentially arranged along the conveying direction of the conveying roller 100 , and the distance between the detection assembly 200 and the plaster scraping assembly 300 is greater than the length of the wood board substrate N.

[0029] The detection component 200 in this embodiment is installed on the conveying roller 100. The detection component 200 has a detection end for detecting defects on the wood substrate N.

[0030] like Figure 3 As shown, in one embodiment, the detection assembly 200 includes a camera 210 and a first fixing frame 220 . The first fixing frame 220 is fixed above the conveying roller 100 , and the camera 210 is installed at the bottom of the first fixing frame 220 .

[0031] The image information captured by the camera 210 can be compared with the information in the database to know the location of the defect on the wood board substrate N. Visual inspection is a conventional method that can be thought of by those skilled in the art.

[0032] The plastering assembly 300 in this embodiment is used for spraying putty onto a wooden board substrate N. Specifically, the plastering assembly 300 includes a plurality of nozzles 310 fixedly disposed above a conveying roller 100, a plurality of feed pipes 320 and a plurality of valves 330. The plurality of nozzles 310 are arranged in sequence along a horizontal direction perpendicular to the conveying roller 100. Discharge ports are formed at the bottom of the plurality of nozzles 310. The tops of the plurality of nozzles 310 are respectively connected to external materials via a plurality of feed pipes 320. A plurality of valves 330 are respectively installed on the plurality of feed pipes 320 to adjust the material flow rate in the feed pipes 320 according to the surface condition of the portion directly facing the wooden board.

[0033] Along the width direction of the wood board substrate N, that is, the horizontal direction perpendicular to the conveying roller 100, multiple nozzles 310 correspond to different areas of the wood board substrate N. According to the defect position detected by the detection component 200 and the transmission speed of the conveying roller 100, it can be known when the defective part moves to the position below the nozzle 310, so as to know when to adjust the valve 330.

[0034] It can be understood that the valve 330 has a first state and a second state. When the flat part of the wooden board is below the nozzle 310, the corresponding valve 330 is in the first state, and the putty flow in the feed pipe 320 is small. When the defective part of the wooden board is below the nozzle 310, the corresponding valve 330 is in the second state, and the putty flow in the feed pipe 320 is large.

[0035] To avoid a blind area for scraping dust, in one embodiment, two adjacent nozzles 310 are arranged close to each other.

[0036] like Figure 5 As shown, in one embodiment, the size of the bottom of the nozzle 310 along the conveying direction of the conveying roller 100 is smaller than the size along the conveying direction perpendicular to the conveying roller 100 to form a duckbill structure.

[0037] In order to provide materials to the feed pipe 320, in one embodiment, the scraper assembly 300 further includes a feeder 340 and a second fixing frame 350, the second fixing frame 350 is fixedly arranged above the conveying roller 100, a plurality of nozzles 310 are connected to the second fixing frame 350, and the feeder 340 is installed on the top of the second fixing frame 350 and communicated with a plurality of feed pipes 320. The feeder 340 includes a material box 351 and a pump 352, and the material box 351 is arranged in communication with the plurality of feed pipes 320 via the pump 352.

[0038] To facilitate the connection between the pump 352 and multiple feed pipes 320, in one embodiment, the feeding piece 340 also includes a transverse tube 353, both ends of which are closed and fixedly connected to the second fixed frame 350, the top of the transverse tube 353 is connected to the pump 352, and the bottom of the transverse tube 353 is connected to multiple feeding pieces 340.

[0039] To facilitate the suspension and fixation of multiple nozzles 310, in one embodiment, the scraping assembly 300 also includes a crossbeam, and the crossbeam has multiple through grooves extending in the vertical direction along its length direction. The multiple nozzles 310 are respectively inserted into the multiple through grooves and fixedly connected to the crossbeam.

[0040] In order to facilitate the control of the opening of the scraper assembly 300 , the present embodiment also includes a sensor, which is installed on the conveying roller 100 and arranged on the side of the scraper assembly 300 close to the detection assembly 200 for detecting the wood board substrate N on the conveying roller 100 .

[0041] It is understandable that the sensor can be implemented by a laser transmitter and a laser receiver. The laser transmitter and the laser receiver are respectively arranged on both sides of the second fixed frame 350. The laser transmitter is set to point to the laser receiver. When the wooden substrate N moves to the position between the laser transmitter and the laser receiver, the laser emitted by the laser transmitter is blocked, and the laser receiver no longer receives the laser signal. At this time, the plaster scraping component 300 can be controlled to work.

[0042] Compared with the prior art: the location of the defect on the wooden board substrate N can be known according to the detection component 200. When the wooden board substrate N passes through the plastering component 300, the multiple nozzles 310 in the plastering component 300 spray putty to the surface of the wooden board substrate N. When the defect on the rice board substrate is facing one of the nozzles 310, the valve 330 can be controlled to increase the material flow in the feed pipe 320 to spray more putty to fill the defect. The surface of the wooden board substrate N is evenly plastered, replacing manual filling, facilitating subsequent plastering work, and improving production efficiency.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
