[0033] 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.

[0034] In this embodiment, a glue coating machine for wood-based sheets relates to the technical field of wood board gluing, and uses a glue dispensing unit 320 to control the amount of glue dispensing to prevent too little or too much glue dispensing. At the same time, a glue scraping unit 330 is provided on the glue coating roller 210 to control the thickness of the glue adhering to the glue coating roller 210 and optimize the quality of the plywood.

[0035] See also Figures 1 to 7 In this embodiment, a glue coating machine for a wood-based sheet includes a base body 100, a rolling assembly 200, and a glue coating assembly 300. The base body 100 can provide effective support and fixation for each component of the entire glue coating machine. The rolling assembly 200 includes a glue coating roller 210, which can roll the surface of the wood-based sheet to apply glue to the wood-based sheet. The glue coating assembly 300 can evenly coat the glue coating roller 210 with glue, so that the glue layer on the surface of the glue coating roller 210 is evenly distributed and has a consistent thickness.

[0036] The glue coating component 300 includes a shell 310, a glue discharging unit 320 and a glue scraping unit 330. The shell 310 includes a glue coating hopper 311 and a support sleeve 312. The glue coating hopper 311 is arranged on the top of the glue coating roller 210. The lower part of the glue coating hopper 311 can output glue relative to the glue coating roller 210. The glue discharging unit 320 is arranged at the outlet of the glue coating hopper 311. By accurately adjusting the glue discharging unit 320, it can be ensured that the amount of glue on the glue coating roller 210 is always maintained within the set range to avoid excessive or insufficient situations, thereby maintaining a consistent glue coating thickness.

[0037] The support sleeve 312 is arranged on the side of the glue coating roller 210, and the glue coating bucket 311 is embedded in the protective sleeve. The glue scraping unit 330 includes a scraper 331 and a sensor 332. The scraper 331 is arranged in a gap relative to the glue coating roller 210. The scraper 331 and the support sleeve 312 are detachably connected. The gap between the scraper 331 and the glue coating roller 210 can be manually adjusted so that the glue thickness of the glue coating roller 210 is consistent with the gap. Excess glue can be scraped off by the scraper 331 to ensure that the glue is evenly distributed on the surface of the glue coating roller 210. The design of the scraper 331 ensures that even if the glue output fluctuates slightly, it can be adjusted through the scraper 331 to ensure consistent glue coating thickness.

[0038] A glue accumulation space for storing glue is formed between the scraper 331, the support sleeve 312 and the glue coating roller 210, and the scraped glue is accumulated in the glue accumulation space. The sensor 332 is arranged in the glue accumulation space, and the sensor 332 can detect the volume of the glue in the glue accumulation space in real time. When the volume of the glue exceeds a certain limit, the sensor 332 is triggered, and the sensor 332 is electrically connected to the glue discharging unit 320. The triggered sensor 332 can control the glue discharging unit 320 to cut off the power supply, cut off the glue supply to the glue coating roller 210, and the glue in the glue accumulation space can replenish the glue coating roller 210 passing through the gap until the glue in the glue accumulation space is consumed. The sensor 332 is electrically linked with the glue discharging unit 320, which can ensure that the glue layer on the surface of the glue coating roller 210 is continuously supplied and has a consistent thickness, thereby realizing precise control and uniform coating of the glue coating thickness, so that the glue coating thickness is always kept constant, and the stability and quality of the glue coating are significantly improved.

[0039] In some embodiments, see Figures 1 to 4A heating plate 331a is provided on one side of the scraper 331 relative to the glue accumulation space. The heating plate 331a is an electric heating plate 331a. The heating plate 331a can heat the glue in the glue accumulation space to increase the temperature of the glue. The increased temperature can reduce the viscosity of the glue, making it easier for the glue to flow, ensuring that the glue is evenly distributed on the glue coating roller 210, reducing the resistance during the glue coating process, and improving the uniformity of the glue coating. At the same time, the heating plate 331a can keep the temperature of the glue in the glue accumulation space within an appropriate range, preventing the glue from thickening or solidifying due to too low a temperature, thereby ensuring the continuity and stability of the glue coating process.

[0040] As a further embodiment, the scraper 331 includes a wedge-shaped portion 331b and a connecting portion 331c arranged relative to the glue coating roller 210, and the connecting portion 331c is provided with a waist-shaped hole, and the bolt is connected to the support sleeve 312 through the waist-shaped hole. The waist-shaped hole (also called an elliptical hole) allows the bolt to have a certain range of movement in the hole. When installing or adjusting the scraper 331, the position and angle of the scraper 331 can be accurately adjusted by moving the bolt. The gap between the scraper 331 and the glue coating roller 210 can be adjusted according to actual needs, thereby adjusting the thickness of the glue layer on the surface of the glue coating roller 210, thereby achieving accurate control of the glue coating thickness and uniform coating.

[0041] In addition, the wedge-shaped portion 331b and the glue coating roller 210 are arranged relative to each other to form a gap, and the end of the wedge-shaped portion 331b is relatively sharp, which can better scrape the glue from the glue coating roller 210 to ensure that the glue on the surface of the glue coating roller 210 is relatively uniform. At the same time, when the glue accumulation space is replenished to the glue coating roller 210, the inclined setting of the wedge-shaped portion 331b is conducive to the relative flow of the glue, and the glue coating roller 210 is replenished with glue.

[0042] In some embodiments, see Figure 5 The glue discharging unit 320 includes two rotatable gear columns 321, which are arranged in the glue coating bucket 311. The two ends of the gear column 321 are respectively connected to the glue coating bucket 311 in rotation. The two gear columns 321 are meshed with each other, and the two gear columns 321 form a gear pump type conveying structure. The wheel columns mesh with each other and rotate synchronously, which can accurately control the delivery amount of the glue liquid. By adjusting the speed and direction of the gear, the flow rate of the glue liquid can be accurately controlled to ensure that the amount of glue liquid on the glue coating roller 210 is always consistent, avoiding too much or too little. The gear column 321 forms a uniform transmission mechanism during the meshing process, which can evenly convey the glue liquid to the surface of the glue coating roller 210, ensuring that the glue liquid will not be blocked or uneven during the conveying process, thereby improving the uniformity and consistency of the glue coating.

[0043] As a further implementation, see Figure 1The glue discharging unit 320 also includes a rotating driving member 322, which is specifically a servo motor. The rotating driving member 322 is rotatably connected to the gear column 321, and the sensor 332 is electrically connected to the rotating driving member 322. The sensor 332 can control the start and stop of the rotating driving member 322. The servo motor can provide high-precision speed and position control. By adjusting the rotation speed of the servo motor, the rotation speed of the gear column 321 can be accurately controlled, thereby accurately controlling the delivery amount of the glue liquid to ensure the stability and uniformity of the glue liquid. The sensor 332 monitors the volume of the glue liquid in the glue accumulation space in real time and feeds back the data to the servo motor. The servo motor automatically adjusts the rotation speed or starts and stops according to the feedback information of the sensor 332, thereby realizing real-time adjustment of the glue liquid delivery amount. This closed-loop control system can respond to changes quickly and maintain the stability and consistency of the glue coating process.

[0044] As another embodiment, the glue discharging unit 320 may be a solenoid valve, which is located at the outlet of the glue coating hopper 311 and controls the outflow of the glue liquid through electromagnetic. The solenoid valve control system can quickly respond and accurately adjust the flow rate of the glue liquid to achieve precise glue discharging control. The solenoid valve can achieve closed-loop control through the sensor 332 and the control system to ensure high precision and consistency of the glue coating process.

[0045] In some embodiments, see Figure 2 , Figure 6 and Figure 7 A glue coating machine for wood-based sheets also includes a preheating component 400, which includes a packaging shell 410, a heating unit 420 and a blasting unit 430 arranged relatively far away from the glue scraping unit 330. The packaging shell 410 is fixedly connected to the support sleeve 312, and the heating unit 420 and the blasting unit 430 are respectively arranged in the packaging shell 410. The heating unit 420 can heat the air from the blasting unit 430 to heat the glue coating roller 210, so that the temperature of the surface of the glue coating roller 210 increases. It can prevent the glue from solidifying on the glue coating roller 210 and prevent the glue layer attached to the board from being uneven in thickness. It can also reduce the viscosity of the glue and improve its fluidity, so that the glue can be more evenly coated on the surface of the wood-based sheet, thereby improving the quality of glue coating.

[0046] In some embodiments, see Figure 6 and Figure 7The heating unit 420 includes an electric heating network 421 fixedly connected to the encapsulation shell 410, and the air blowing unit 430 includes a fan 431 fixedly connected to the encapsulation shell 410. The electric heating network 421 is arranged between the fan 431 and the glue coating roller 210. The electric heating network 421 has a large heating area and efficient heat conduction performance, and can quickly heat the air passing through. The cold air blown out by the fan 431 is heated when passing through the electric heating network 421, and the hot air can quickly and evenly cover the surface of the glue coating roller 210, thereby improving the heating efficiency and uniformity.

[0047] In some embodiments, see Figure 1 and Figure 2 The rolling assembly 200 also includes a supporting roller 220. The supporting roller 220 and the glue coating roller 210 are rotatably connected to the base body 100 through bearings. The supporting roller 220 is arranged along the length direction of the glue coating roller 210 and is arranged on the lower side of the glue coating roller 210. A space for rolling the wood substrate board is formed between the glue coating roller 210 and the supporting roller 220. The supporting roller 220 provides stable support on the lower side of the glue coating roller 210, so that the wood substrate sheet can maintain a stable and uniform pressure when passing through the glue coating roller 210, thereby ensuring that the glue is evenly coated on the surface of the board, thereby improving the quality and consistency of the glue coating.

[0048] Two servo motors are provided outside the base 100, and the two servo motors are rotatably connected to the support roller 220 and the glue coating roller 210 respectively. The servo motors can drive the support roller 220 and the glue coating roller 210 to rotate relative to each other to complete the roller gluing of the wood substrate board.

[0049] Workflow: First, start the support roller 220 and the glue roller 210 so that they rotate relative to each other. Then, put in a wood substrate board and start the gear column 321. The gear column 321 rotates relative to each other, and glue is added to the wood substrate board. The glue adheres to the surface of the glue roller 210 to form a glue layer. The excessively thick glue layer is scraped off by the scraper 331, so that the glue layer on the surface of the glue roller 210 is evenly distributed and has a uniform thickness.

[0050] The above description is only a preferred specific implementation 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 covered by the present invention.
