Description

Technical Field

[0001] This invention relates to the field of eco-board processing technology, and in particular to a high-efficiency eco-board drying machine. Background Technology

[0002] Ecological board is a type of engineered wood product, also known as melamine board or paint-free board. It is typically composed of a substrate and a surface decorative layer, and is formed through high-temperature and high-pressure processing.

[0003] Specifically, the base material of eco-boards is mostly medium-density fiberboard (MDF) or particleboard, and some are made primarily from wood chips, wood fibers, or plywood core materials. The surface is made of melamine resin decorative paper or other decorative materials, formed through a hot-pressing process, which can both mimic the texture of solid wood and achieve diverse design styles.

[0004] Eco-friendly boards are widely used due to their environmental friendliness, rich colors, wear resistance, high temperature resistance, and pollution resistance, making them a common choice for home decoration. In addition, eco-friendly boards also have advantages such as relatively low cost, simple processing, easy cutting and installation, and easy cleaning.

[0005] According to publicly available patent CN218722931 U, a dryer for processing eco-boards includes a shell. A feed inlet is located at the outer end of the shell. A drive motor is fixedly mounted at the outer end of the shell. A sprocket is rotatably connected to the inner wall of the shell. The output shaft of the drive motor is fixedly mounted to the outer end of the sprocket. A chain is meshed with the outer end of the sprocket. A rotating rod is fixedly mounted at the outer end of the sprocket. A heater is fixedly mounted on the inner wall of the shell. In developing this invention, the inventors discovered that at least the following problems remain unsolved in the prior art: The feed inlet draws the eco-boards into the internal parts of the conveying device, squeezing the rotating shaft and causing it to rotate the connecting rod. The rotating shaft, driven by gravity, presses the ecological board against itself, increasing the contact between the board and the outer end of the rotating rod. A drive motor then drives a sprocket, causing the rotating rod to move the ecological board. Heaters and heating plates bake both sides of the ecological board, accelerating the drying process. Traditionally, both the discharge and inlet ports are open, allowing heat to escape easily. This not only increases the time it takes for the temperature inside the shell to rise but also causes uneven temperature distribution within the shell, resulting in uneven heating of the ecological board during drying and affecting its drying effect and efficiency. Therefore, we propose a high-efficiency dryer for processing ecological boards. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-efficiency drying machine for processing eco-friendly boards.

[0007] To achieve the above objectives, the technical solution adopted by this invention is: a high-efficiency drying machine for processing ecological boards, comprising:

[0008] The main body includes a housing with openings at both ends. A one-way exhaust valve is connected to the top of the housing. A drive motor is installed at one outer end of the housing, and a drying mechanism is provided at the end of the housing near the drive motor.

[0009] The conveying mechanism includes two baffles, which are respectively installed on both sides of the inner cavity of the housing. Two drive rollers are rotatably connected between the two baffles. Two sprockets are installed on the outer sides of each of the two drive rollers. A chain is provided on the sprocket between the two drive rollers. Multiple Z-shaped connecting rods are installed on the ends of the two chains near the baffles. Connecting blocks are connected to the multiple Z-shaped connecting rods. Sealing plates are connected between two opposite connecting blocks on the two chains. L-shaped side plates are fixedly connected to both sides of one end of the sealing plate. The width of the sealing plate is adapted to the width of the inner cavity of the housing.

[0010] Preferably, the drying mechanism includes hot air blowers installed at both ends of the housing, and the air outlets of the two hot air blowers are connected to air inlet pipes, and the two air inlet pipes pass through the housing and are placed in the inner cavity of the housing.

[0011] Preferably, the housing is a hollow structure, and multiple air outlets are provided on both sides of the inner cavity of the housing, and the multiple air outlets are connected to the hollow structure of the housing, and the air inlet pipe is connected to the hollow structure of the housing.

[0012] Preferably, the two ends of the housing are respectively provided with a feeding mechanism and a discharging mechanism. The feeding mechanism includes a first belt conveyor provided at the left opening of the housing, and the discharging mechanism includes a second belt conveyor provided at the right opening of the housing.

[0013] Preferably, annular limiting blocks are installed at opposite ends of the two baffles, the connecting block is U-shaped, the connecting block is sleeved on the outside of the annular limiting block, and guide wheels are installed on both sides of the inner cavity of the connecting block, and the guide wheels are in contact with the outside of the annular limiting block.

[0014] Preferably, multiple ball bearings are rotatably connected to the top of the inner cavity of the L-shaped side plate and the opposite sealing plate, and multiple through holes are opened on the side of the L-shaped side plate.

[0015] Preferably, an inverted U-shaped frame is installed between the top two sides of the first belt conveyor, the top of the inverted U-shaped frame slides through a limiting plate, and both ends of the inverted U-shaped frame are provided with top screws, and both top screws are in contact with the surface of the limiting plate.

[0016] Preferably, an anti-slip drop plate is installed between the top two sides of the second belt conveyor, the bottom of the anti-slip drop plate is notched, and a guide plate is inclinedly connected between the two sides of the second belt conveyor below the anti-slip drop plate.

[0017] Preferably, the conveyor belt of the first belt conveyor is on the same horizontal line as the horizontally placed sealing plate.

[0018] Compared with the prior art, the present invention has the following beneficial effects: by setting up a main body mechanism, a conveying mechanism and a drying mechanism, the heat of drying is prevented from being lost from both ends of the shell, thereby shortening the temperature rise time inside the shell and preventing uneven temperature inside the shell caused by heat loss. This ensures that the ecological board is heated evenly during the drying process, further improving the drying effect and efficiency of the ecological board.

[0019] When the eco-board is conveyed into the shell for drying, the drying heat is evenly distributed in the shell through multiple air outlets. Then, the ball bearings prevent the eco-board from completely sticking to the L-shaped side plate and the sealing plate. At the same time, the through holes can blow heat from the side of the L-shaped side plate to the eco-board between the L-shaped side plates, thereby increasing the contact area between the eco-board and the heat, and further improving the drying efficiency and effect of the eco-board.

[0030] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0031] like Figures 1 to 8 The high-efficiency ecological board processing dryer shown includes:

[0032] The main body includes a housing 101, both ends of which are open. The top of the housing 101 is connected to an exhaust one-way valve 102. A drive motor 103 is installed on one side of the housing 101. A drying mechanism is provided on the side of the housing 101 near the drive motor 103.

[0033] The conveying mechanism includes two baffles 301, which are respectively installed on both sides of the inner cavity of the housing 101. Two drive rollers 302 are rotatably connected between the two baffles 301. The drive end of the drive motor 103 rotatably passes through the housing 101 and is connected to the center of one of the drive rollers 302. Two sprockets 309 are installed on the outer sides of each of the two drive rollers 302. A chain 306 is provided on the sprocket 309 between the two drive rollers 302. Multiple Z-shaped connecting rods 308 are installed on the end of each chain 306 near the baffles 301. Connecting blocks 307 are connected to each of the multiple Z-shaped connecting rods 308. A sealing plate 303 is connected between the two opposite connecting blocks 307 on the two chains 306. L-shaped side plates 304 are fixedly connected to both sides of one end of the sealing plate 303. The width of 03 is adapted to the inner cavity width of the housing 101. During operation, the ecological board to be dried is inserted between the two L-shaped side plates 304. Then, the drive motor 103 drives the drive roller 302 to rotate. In conjunction with the sprocket 309 and chain 306, the ecological board placed on the sealing plate 303 rotates and is placed inside the housing 101 for drying by the drying mechanism. When the ecological board is being dried, the sealing plate 303 seals the openings at both ends of the housing 101, thereby drying the ecological board in the sealed space formed by the housing 101 and the sealing plate 303. This prevents the heat from being lost from both ends of the housing 101, thus shortening the temperature rise time inside the housing 101. It also prevents the heat loss inside the housing 101 from causing uneven temperature inside the housing 101, thus ensuring that the ecological board is heated evenly during the drying process, further improving the drying effect and efficiency of the ecological board.

[0034] As a further embodiment of the present invention, the drying mechanism includes hot air blowers 201 installed at both ends of the housing 101. The air outlets of both hot air blowers 201 are connected to air inlet pipes 202. Both air inlet pipes 202 penetrate the housing 101 and are located within the inner cavity of the housing 101. The housing 101 has a hollow structure. Multiple air outlets 104 are provided on both sides of the inner cavity of the housing 101, and all multiple air outlets 104 are connected to the hollow structure of the housing 101. The air inlet pipes 202 are connected to the hollow structure of the housing 101. The top of the inner cavity of the L-shaped side plate 304 and the corresponding dense... Multiple ball bearings 305 are rotatably connected to the sealing plate 303. Multiple through holes 312 are opened on the side of the L-shaped side plate 304. When the ecological board is transported into the housing 101 for drying, the drying heat is evenly distributed in the housing 101 through the multiple air outlets 104. Then, the ball bearings 305 prevent the ecological board from being completely in contact with the L-shaped side plate 304 and the sealing plate 303. At the same time, the through holes 312 can blow heat from the side of the L-shaped side plate 304 to the ecological board between the L-shaped side plates 304, thereby increasing the contact area between the ecological board and the heat, and further improving the drying efficiency and effect of the ecological board.

[0035] As a further embodiment of the present invention, a feeding mechanism and a discharging mechanism are respectively provided at both ends of the housing 101. The feeding mechanism includes a first belt conveyor 401 provided at the left opening of the housing 101. The conveyor belt of the first belt conveyor 401 is on the same horizontal line as the horizontally placed sealing plate 303. The discharging mechanism includes a second belt conveyor 501 provided at the right opening of the housing 101. The first belt conveyor 401 facilitates the conveying of the ecological board to be dried between the two L-shaped side plates 304, and the second belt conveyor 501 facilitates the conveying and unloading of the dried ecological board, thereby eliminating the need for manual feeding and unloading and improving the automation level of the dryer.

[0036] As a further embodiment of the present invention, an annular limiting block 311 is installed at one end of each of the two baffles 301. The connecting block 307 is U-shaped and is sleeved on the outside of the annular limiting block 311. Guide wheels 310 are installed on both sides of the inner cavity of the connecting block 307, and the guide wheels 310 contact the outside of the annular limiting block 311. The annular limiting ring can guide the movement of the connecting block 307, thereby improving the stability of the connecting block 307 when it moves, and thus improving the stability of the sealing plate 303 when it moves. At the same time, the guide wheels 310 reduce the friction between the connecting block 307 and the annular limiting block 311, thereby facilitating the guided movement of the connecting block 307 on the outside of the annular limiting block 311.

[0037] As a further embodiment of the present invention, an inverted U-shaped frame 402 is installed between the top two sides of the first belt conveyor 401. The top of the inverted U-shaped frame 402 slides through a limiting plate 403. Both ends of the inverted U-shaped frame 402 are provided with a set screw 404, and both set screws 404 are in contact with the surface of the limiting plate 403. By turning the set screws 404, the distance between the limiting plate 403 and the conveyor belt of the first belt conveyor 401 is adjusted to be the same as the thickness of the ecological board to be conveyed. Thus, when the ecological boards are stacked and conveyed, the ecological boards at the top of the stack are blocked by the limiting plate 403. When the contact friction between the bottom ecological board and the conveyor belt of the first belt conveyor 401 is greater than the friction between the bottom ecological board and the top ecological board, the bottom ecological board is conveyed between the limiting plate 403 and the conveyor belt of the first belt conveyor 401, thereby enabling the stacked ecological boards to be fed one by one.

[0038] As a further embodiment of the present invention, an anti-slip drop plate 503 is installed between the top two sides of the second belt conveyor 501. The bottom of the anti-slip drop plate 503 is notched. A guide plate 502 is inclinedly connected between the two sides of the second belt conveyor 501 below the anti-slip drop plate 503. With the anti-slip drop plate 503, when the sealing plate 303 rotates and tilts downward, the anti-slip drop plate 503 prevents the dried ecological board from sliding down. When the sealing plate 303 rotates and tilts at the same angle as the guide plate 502, the dried ecological board, in conjunction with the ball bearing 305, reduces the friction between itself and the sealing plate 303. Thus, the dried ecological board automatically slides onto the second belt conveyor 501 for conveying and unloading, thereby ensuring that the dried ecological board can be stably placed on the second belt conveyor 501 for stable unloading.

[0039] Working principle of this invention:

[0040] First, by turning the set screw 404, the distance between the limiting plate 403 and the conveyor belt of the first belt conveyor 401 is adjusted to be the same as the thickness of the ecological board to be conveyed. Thus, when the ecological boards are stacked and conveyed, the ecological boards at the top are blocked by the limiting plate 403. When the friction between the bottom ecological board and the conveyor belt of the first belt conveyor 401 is greater than the friction between the bottom ecological board and the ecological board above it, the bottom ecological board is conveyed from between the limiting plate 403 and the conveyor belt of the first belt conveyor 401 to the two L-shaped side plates 3. Between 04, the drive motor 103 is started to drive the drive roller 302 to rotate, which, together with the sprocket 309 and chain 306, drives the ecological board placed on the sealing plate 303 to rotate and be placed inside the housing 101. Then, the hot air blower 201 is started to distribute the drying heat evenly inside the housing 101 through multiple air outlets 104. Then, the ball bearings 305 prevent the ecological board from completely sticking to the L-shaped side plate 304 and the sealing plate 303. At the same time, the through holes 312 can blow heat from the side of the L-shaped side plate 304 to the ecological board between the L-shaped side plates 304. On the ecological board, the sealing plate 303 seals the openings at both ends of the shell 101 during drying, thereby drying the ecological board within the sealed space formed by the shell 101 and the sealing plate 303. This prevents heat loss from both ends of the shell 101, shortens the temperature rise time inside the shell 101, and avoids uneven temperature distribution inside the shell 101 due to heat loss. This ensures uniform heating of the ecological board during the drying process, further improving its performance. The high-efficiency drying effect of the ecological board is achieved by rotating and tilting the sealing plate 303 downwards when the sealing plate 303 is dried. The anti-slip plate 503 prevents the dried ecological board from sliding down. When the rotation and tilt of the sealing plate 303 are the same as the tilt angle of the guide plate 502, the dried ecological board, together with the ball bearing 305, reduces the friction between itself and the sealing plate 303. As a result, the dried ecological board automatically slides down onto the second belt conveyor 501 for conveying and unloading, thus ensuring that the dried ecological board can be stably placed on the second belt conveyor 501 for stable unloading.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
