Description

Technical Field

[0001] This invention relates to the field of fiberboard processing technology, and more specifically to a fiberboard processing production line. Background Technology

[0002] Fiberboard is a type of board made from wood fibers or other plant fibers, primarily used in furniture manufacturing, building decoration, and packaging industries. The following is general background technology for fiberboard processing: Raw Material Processing: Raw materials are typically wood fibers, including wood chips, sawdust, and wood fibrous material. These raw materials require processing, including crushing, screening, and drying, to ensure the quality and stability of the fiberboard. Production Processes: Fiberboard production processes mainly include three common methods: particleboard processing, fiberboard processing, and chipboard processing. Particleboard processing involves mixing wood chips with adhesives and then hot-pressing them; fiberboard processing involves mixing wood fibrous material with adhesives and then hot-pressing it; chipboard processing involves mixing sawdust with adhesives and then hot-pressing it. Each process has its characteristics and applicable scenarios. Equipment Selection: Fiberboard processing requires a series of specialized equipment, including wood crushers, drying equipment, particle machines, fiberboard forming machines, and hot presses. Different processes require different types of equipment, and the selection of equipment directly affects production efficiency and product quality. Processing technology: Fiberboard processing involves technical issues such as the selection and use of adhesives, control of molding processes, and adjustment of hot pressing parameters. During production, each step needs to be strictly controlled to ensure that the final product meets quality requirements.

[0003] Existing fiberboard processing production lines mostly use water cooling to rapidly cool the extruded semi-finished products. While this method can indeed improve work efficiency to some extent, fiberboard is a type of engineered wood product made from wood fibers or other plant fibers and bonded with urea-formaldehyde resin or other suitable adhesives. After absorbing moisture, the difference in expansion force causes the board to warp and deform. The surface of hard fiberboard is hard, making it difficult to nail and it has poor water resistance. Even though rapid drying can reduce the damage to fiberboard caused by direct water cooling, this cooling method still cannot improve the yield rate of fiberboard.

[0004] In view of the above, in order to overcome the above technical problems, the present invention designs a fiberboard processing production line, which solves the above technical problems. Summary of the Invention

[0005] The technical objective of this invention is to improve the traditional water-cooling direct cooling method. By improving the existing production line, a new fiberboard processing production line is proposed, which abandons the traditional cooling method of using water-cooling direct contact to cool semi-finished fiberboard.

[0006] To achieve the above-mentioned technical objectives, the present invention provides the following technical solution:

[0007] A fiberboard processing production line includes a drive roller, a transmission shaft, a circulation mechanism, and a cooling mechanism. The drive roller rotates under the drive of the transmission shaft, driving multiple cooling mechanisms in a cyclical motion. The drive roller is one of the core components of the production line. It is mounted on the transmission shaft and rotates under the drive of an external power source. The rotational motion of the drive roller is the foundation of the entire production line's operation; it transmits power to other components through the transmission shaft, propelling the normal operation of the production line.

[0008] The drive shaft is used to drive the drive roller to rotate under the influence of an external power source. As a medium connecting the drive roller and the external power source, the drive shaft is responsible for transmitting power to the drive roller. Through the rotation of the drive shaft, the energy provided by the external power source is effectively transferred to the drive roller, thereby starting the operation of the entire production line.

[0009] The circulation mechanism is installed on one side of the drive roller. It is used to replace the cooling water in the cooling mechanism. Located on one side of the drive roller, its main function is to circulate and replace the cooling water in the cooling mechanism. Through precise control, the circulation mechanism ensures that the cooling water is effectively recycled within the cooling mechanism, thereby maintaining the stability and durability of the cooling effect.

[0010] The cooling system is a crucial component of the production line. Its primary task is to directly cool the fiberboard during the manufacturing process using cooling water flowing through internal channels. The cooling system is positioned around the drive rollers and circulation mechanism to ensure complete coverage of the fiberboard. Through direct contact between the cooling water and the fiberboard, the temperature of the fiberboard is effectively reduced, promoting rapid forming.

[0011] The circulation mechanism includes a drum shell, an inlet pipe, an outlet pipe, an inlet cavity, an outlet cavity, a baffle, and a first valve assembly. The drum shell serves as the external frame of the circulation mechanism, providing support and protection for the entire structure. Its design aims to support and secure the internal components while possessing sufficient strength and durability to withstand various forces and pressures during processing.

[0012] The inlet pipe and the outlet pipe are located on both sides of the drum shell, and are used for water entry and exit, respectively. The inlet pipe introduces cooling water into the circulation mechanism, while the outlet pipe discharges the processed water to maintain the circulation and renewal of the cooling water, ensuring the continuity and stability of its cooling effect.

[0013] The drum shell has two cavities inside. The one connected to the water inlet pipe is designated as the water inlet cavity, and the one connected to the water outlet pipe is designated as the water outlet cavity. The water inlet cavity, connected to the water inlet pipe, receives and stores the cooling water entering the circulation mechanism. The water outlet cavity, connected to the water outlet pipe, temporarily stores the processed water and discharges it from the system.

[0014] The baffle is positioned between the inlet and outlet chambers. Its main function is to separate the inlet and outlet areas, preventing mixing between them. The baffle ensures that the cooling water maintains its original flow direction and state within the circulation mechanism, thereby effectively completing the cooling task. The first valve assembly is installed on the outside of both the inlet and outlet chambers.

[0015] The first valve assembly includes a first connecting shell, a first connecting cavity, a first fixing plate, a first spring, a first limiting block, a first movable block, a mating groove, and a sealing ring. The first connecting shell is installed on the side of the rolling shell and serves as the outer housing of the first valve assembly. The first connecting cavity is located within the first connecting shell and is a chamber inside the shell used to accommodate the valve's internal components and the medium. This design allows the first valve to be tightly installed on the production line and is easy to maintain and operate.

[0016] Within the first connecting chamber, a first fixing plate is installed. Located in the center of the chamber, it serves to fix and support the internal components of the valve. The lower end of the first spring is engaged with the top of the first fixing plate, using elastic force to maintain the stability and mobility of the first movable block. The first limit block is installed above the first fixing plate to restrict the range of movement of the first movable block, ensuring that the opening and closing actions of the valve are controlled.

[0017] The first movable block, mounted on the upper end of the first spring, is a moving component in the valve assembly responsible for controlling the flow and volume of cooling water. A mating groove is formed on the top of the first movable block for cooperation with other components, enabling normal valve operation and adjustment. Simultaneously, a sealing ring is installed on the top of the first movable block to ensure the valve's sealing performance, prevent media leakage, and guarantee the safety and stability of the production process.

[0018] The No. 1 connecting valve's outer casing is cylindrical, with its upper and lower surfaces designed as trapezoidal tiers, which helps increase the valve's structural stability and strength. The cylindrical design provides uniform support and pressure distribution, allowing the valve to withstand greater internal pressure without easily deforming or being damaged. Simultaneously, the trapezoidal tiers allow for better connection between the valve and other components, ensuring sealing and stability.

[0019] Secondly, the upper part of the first connecting chamber is tapered, which improves fluid flow. The tapered design reduces fluid flow resistance and energy loss, thereby increasing the flow rate and volume of cooling water. This helps to accelerate the flow of cooling water inside the valve, improve cooling efficiency, and reduce energy consumption.

[0020] The trapezoidal cross-sectional shape of the first moving block helps improve the valve's control performance. The trapezoidal cross-section design increases the contact area between the moving block and the sealing surface, improving sealing performance and preventing media leakage. Simultaneously, the trapezoidal cross-section shape reduces the inertia of the moving block, making the valve's opening and closing actions more flexible and rapid, thus improving the valve's response speed and adjustment accuracy.

[0021] The first limiting block is set as a ring, and the inner diameter of the first limiting block is smaller than the bottom diameter of the first movable block. Thus, the first limiting block can limit the range of motion of the first movable block. The sealing convex is arranged around the first movable block and then arranged outward at equal distances, thereby improving the sealing performance during the water circulation process.

[0022] The cooling mechanism includes a cooling plate, connecting hinges, a contact plate, a contact groove, anti-slip balls, and a second valve assembly. The cooling plate is mounted on the outside of the drive roller, the connecting hinges are mounted on both sides of the cooling plate, the contact plate is mounted on the side of the cooling plate, the contact groove is formed on the contact plate, the anti-slip balls are mounted on both sides of the contact plate, and the second valve assembly is mounted on the back of the cooling plate. The contact plate is made of pure copper, and the contact groove is V-shaped to accelerate the cooling rate of the fiberboard. The anti-slip balls are made of rubber and are used to clamp the fiberboard and move it into the next process flow.

[0023] The cooling plate includes an inlet channel, a circulation channel, an outlet channel, and an intercepting block. The inlet channel is located on the axis inside the cooling plate, the circulation channel is located on both sides of the inlet channel, the outlet channel is located above the inlet channel, and the intercepting block is installed in the middle of the inlet and outlet channels. Low-temperature cooling water enters the inlet channel through the second valve assembly, then passes through the circulation channel and finally exits from the second valve assembly installed above the outlet channel, thus completing the water circulation and ensuring that the cooling plate is filled with low-temperature cooling water before contacting the fiberboard, thereby ensuring the cooling effect.

[0024] The second valve assembly includes a second connecting shell, a second connecting cavity, a second fixed plate, a second spring, a second limiting block, a second movable block, a pushing column, a sealing layer, and a sealing concave ring. The second connecting shell is located below the cooling plate, the second connecting cavity is formed within the second connecting shell, the second fixed plate is installed in the middle of the connecting cavity, the lower end of the second spring is engaged with the upper part of the second fixed plate, the second limiting block is installed above the second fixed plate, the second movable block is installed at the upper end of the second spring, the pushing column is installed above the second movable block, the sealing layer is located on the second connecting shell, and the sealing concave ring is formed on the sealing layer. The working principle of the second valve assembly is similar to that of the first valve assembly, except that the pushing column and the mating groove cooperate to move both the first and second movable blocks above the first and second limiting blocks. During this period, the sealing convex ring and the sealing concave ring cooperate to ensure sealing.

[0025] The beneficial effects of this invention are as follows:

[0026] 1. This invention improves upon traditional water-cooling direct cooling methods by incorporating a circulation and cooling mechanism. Through modifications to existing production lines, it proposes a new fiberboard processing line that abandons the traditional method of direct water-cooling of semi-finished fiberboard. Compared to directly using air or other cooling media, water-cooled cooling plates can more effectively absorb and disperse heat. This reduces energy consumption, lowers production costs, and minimizes environmental impact, meeting energy conservation and emission reduction requirements. Furthermore, it achieves uniform cooling of the fiberboard surface, preventing board deformation or quality problems caused by localized overheating. It ensures rapid cooling of the entire fiberboard after the hot-pressing process, resulting in better flatness and surface quality in the product.

[0027] 2. The present invention uses water-cooled cooling plates for indirect cooling, which can accelerate the production speed of fiberboard production lines. Since water-cooled cooling plates can cool down more quickly and do not require air drying or baking processes to remove water mist residue, production efficiency is greatly improved. Furthermore, by directly integrating the cooling process into the production line, the investment cost of fixed equipment is reduced, thus shortening the production cycle, improving production efficiency, and increasing the production line's capacity.

Detailed Implementation

[0038] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0039] like Figure 1-7As shown, a fiberboard processing production line includes a drive roller 1, a transmission shaft 2, a circulation mechanism 3, and a cooling mechanism 4. The drive roller 1 rotates under the drive of the transmission shaft 2, driving multiple cooling mechanisms 4 in a cyclical motion. The drive roller 1 is one of the core components of the production line. It is mounted on the transmission shaft 2 and rotates under the drive of an external power source. The rotational motion of the drive roller 1 is the foundation of the entire production line operation; it transmits power to other components through the transmission shaft 2, propelling the normal operation of the production line.

[0040] The drive shaft 2 is used to drive the drive roller 1 to rotate under the drive of an external power source. As a medium connecting the drive roller 1 and the external power source, the drive shaft 2 is responsible for transmitting power to the drive roller 1. Through the rotation of the drive shaft 2, the energy provided by the external power source is effectively transmitted to the drive roller 1, thereby starting the operation of the entire production line.

[0041] The circulation mechanism 3 is installed on one side of the drive roller 1. The circulation mechanism 3 is used to replace the cooling water in the cooling mechanism 4. Located on one side of the drive roller 1, its main function is to circulate and replace the cooling water in the cooling mechanism 4. Through precise control, the circulation mechanism 3 ensures that the cooling water is effectively recycled in the cooling mechanism 4, thereby maintaining the stability and durability of the cooling effect.

[0042] The cooling mechanism 4 is a crucial component of the production line. Its primary task is to directly cool the fiberboard during the manufacturing process using cooling water within its internal flow channels. The cooling mechanism 4 is positioned around the drive rollers 1 and the circulation mechanism 3 to ensure complete coverage of the fiberboard. Through direct contact between the cooling water in the cooling mechanism 4 and the fiberboard, the temperature of the fiberboard is effectively reduced, promoting rapid forming.

[0043] like Figure 2 As shown, the circulation mechanism 3 includes a drum housing 31, an inlet pipe 32, an outlet pipe 33, an inlet cavity 34, an outlet cavity 35, a baffle 36, and a first valve assembly 37. The drum housing 31 serves as the external frame of the circulation mechanism 3, providing support and protection for the entire structure. Its design aims to support and secure the internal components while possessing sufficient strength and durability to withstand various forces and pressures during processing.

[0044] The inlet pipe 32 and the outlet pipe 33 are located on both sides of the drum shell 31, and are used for water entry and exit, respectively. The inlet pipe 32 introduces cooling water into the circulation mechanism 3, while the outlet pipe 33 discharges the processed water to maintain the circulation and renewal of the cooling water, ensuring the continuity and stability of its cooling effect.

[0045] The drum housing 31 has two cavities inside. The cavity that communicates with the water inlet pipe 32 is designated as the water inlet cavity 34, and the cavity that communicates with the water outlet pipe 33 is designated as the water outlet cavity 35. The water inlet cavity 34 is connected to the water inlet pipe 32 and is used to receive and store the cooling water entering the circulation mechanism 3. The water outlet cavity 35 is connected to the water outlet pipe 33 and is used to temporarily store the processed water and discharge it from the system.

[0046] The baffle 36 is disposed between the inlet cavity 34 and the outlet cavity 35. Its main function is to separate the inlet and outlet areas, preventing mixing. The presence of the baffle 36 ensures that the cooling water maintains its original flow direction and state within the circulation mechanism 3, thereby effectively completing the cooling task. The first valve assembly 37 is installed on the outside of the inlet cavity 34 and the outlet cavity 35.

[0047] like Figure 3 As shown, the first valve assembly 37 includes a first connecting housing 371, a first connecting cavity 372, a first fixing plate 373, a first spring 374, a first limiting block 375, a first movable block 376, a mating groove 377, and a sealing protrusion ring 378. The first connecting housing 371 is installed in the side of the rolling housing 31 and is the outer shell of the first valve assembly 37. The first connecting cavity 372 is formed in the first connecting housing 371 and is a chamber located inside the first connecting housing 371, used to accommodate the internal components of the valve and the medium. This design allows the first valve to be tightly installed on the production line and is easy to maintain and operate.

[0048] Within the first connecting cavity 372, a first fixing plate 373 is installed. Located in the center of the cavity, it serves to fix and support the internal components of the valve. The lower end of a first spring 374 is engaged with the top of the first fixing plate 373, using elastic force to maintain the stability and mobility of the first movable block 376. A first limit block 375 is installed above the first fixing plate 373 to limit the range of movement of the first movable block 376, ensuring that the opening and closing actions of the valve are controlled.

[0049] The first movable block 376 is mounted on the upper end of the first spring 374. It is a moving part in the valve assembly, responsible for controlling the flow and volume of cooling water. A mating groove 377 is formed on the top of the first movable block 376 for cooperation with other components to achieve normal valve operation and adjustment. Simultaneously, a sealing ring 378 is installed on the top of the first movable block 376, its function being to ensure the valve's sealing performance, prevent media leakage, and guarantee the safety and stability of the production process.

[0050] The No. 1 Connector housing 371 is cylindrical with trapezoidal bases on both the top and bottom, which helps increase the valve's structural stability and strength. The cylindrical design provides even support and pressure distribution, allowing the valve to withstand greater internal pressure without easily deforming or being damaged. Simultaneously, the trapezoidal base design allows for better connection between the valve and other components, ensuring sealing and stability.

[0051] Secondly, the upper part of the first connecting cavity 372 is designed in a conical shape, which helps improve fluid flow. The conical design reduces fluid flow resistance and energy loss, thereby increasing the flow rate and volume of cooling water. This helps to accelerate the flow of cooling water inside the valve, improve the cooling effect, and reduce energy consumption.

[0052] The trapezoidal cross-sectional shape of the moving block 376 helps improve the valve's control performance. The trapezoidal cross-section design increases the contact area between the moving block and the sealing surface, improving sealing performance and preventing media leakage. Simultaneously, the trapezoidal cross-section shape reduces the inertia of the moving block, making the valve's opening and closing actions more flexible and rapid, thus improving the valve's response speed and adjustment accuracy.

[0053] The first limiting block 375 is set as a ring, and the inner diameter of the first limiting block 375 is smaller than the bottom diameter of the first movable block 376. Thus, the first limiting block 375 can limit the range of motion of the first movable block 376. The sealing convex ring 378 is set outward at equal distances around the first movable block 376, thereby improving the sealing performance during the water circulation process.

[0054] like Figure 4As shown, the cooling mechanism 4 includes a cooling plate 41, a connecting hinge 42, a contact plate 43, a contact groove 44, an anti-slip ball 45, and a second valve assembly 46. The cooling plate 41 is mounted on the outside of the drive roller 1, the connecting hinge 42 is mounted on both sides of the cooling plate 41, the contact plate 43 is mounted on the side of the cooling plate 41, the contact groove 44 is formed on the contact plate 43, the anti-slip ball 45 is mounted on both sides of the contact plate 43, and the second valve assembly 46 is mounted on the back of the cooling plate 41. The contact plate 43 is made of pure copper, and the contact groove 44 is V-shaped, which can accelerate the cooling rate of the fiberboard. The anti-slip ball 45 is made of rubber and is used to clamp the fiberboard and drive it into the next process flow.

[0055] like Figure 5 As shown, the cooling plate 41 includes an inlet channel 411, a circulation channel 412, an outlet channel 413, and an intercepting block 414. The inlet channel 411 is located on the axis inside the cooling plate 41. The circulation channel 412 is located on both sides of the inlet channel 411. The outlet channel 413 is located above the inlet channel 411. The intercepting block 414 is installed between the inlet channel 411 and the outlet channel 413. Low-temperature cooling water enters the inlet channel 411 through the second valve assembly 46, then passes through the circulation channel 412, and finally exits from the second valve assembly 46 installed above the outlet channel 413, thus completing the water circulation and ensuring that the cooling plate 41 is filled with low-temperature cooling water before contacting the fiberboard, thereby ensuring the cooling effect.

[0056] like Figure 7As shown, the second valve assembly 46 includes a second connecting shell 461, a second connecting cavity 462, a second fixing plate 463, a second spring 464, a second limiting block 465, a second movable block 466, a pushing column 467, a sealing layer 468, and a sealing concave ring 469. The second connecting shell 461 is disposed below the cooling plate 41, the second connecting cavity 462 is formed in the second connecting shell 461, the second fixing plate 463 is installed in the middle of the connecting cavity, the lower end of the second spring 464 is engaged with the upper part of the second fixing plate 463, the second limiting block 465 is installed above the second fixing plate 463, and the second movable block 466... Block 466 is installed on the upper end of spring 464, the push post 467 is installed above movable block 466, the sealing layer 468 is disposed on the upper part of connecting housing 461, and the sealing concave ring 469 is formed on the sealing layer 468. The working principle of valve assembly 46 is similar to that of valve assembly 37, except that the push post 467 and the mating groove 377 cooperate to move movable block 376 and movable block 466 above limit block 375 and limit block 465, respectively. During this period, sealing convex ring 378 and sealing concave ring 469 cooperate to ensure sealing.

[0057] During operation, the transmission shaft 2 rotates under the drive of an external power source, thereby driving the circulation mechanism 3 and the cooling mechanism 4 to rotate. The inlet pipe 32 and outlet pipe 33 of the circulation mechanism 3 are respectively connected to water pumps to ensure the power of the circulating water.

[0058] When the cooling mechanism 4 rotates on the circulation mechanism 3, the pushing column 467 and the mating groove 377 cooperate with each other, thereby driving the first movable block 376 and the second movable block 466 to move downwards until they are stopped by the first limit block 375 and the second limit block 465. At this time, the sealing concave ring 469 and the sealing convex ring 378 cooperate with each other to ensure sealing. Due to the special shape of the pushing column 467, the water can flow quickly. The cooling water flows into the cooling plate 41 from the water inlet cavity 34, and after passing through the water inlet channel 411, the circulation channel 412 and the water outlet channel 413, it flows into the water outlet cavity 35, thereby realizing the replacement of the cooling water and ensuring that the cooling plate 41 contains low temperature cooling water.

[0059] The upper and lower cooling plates 41 clamp the fiberboard and move it forward. The anti-slip ball 45 is used to prevent the cooling plate 41 from moving. The contact plate 43 directly contacts the fiberboard and cools it down. Finally, it is sent to the next process flow to complete the cooling.
