Description

Technical Field

[0001] This invention relates to the field of particleboard processing technology, and more particularly to a multi-channel drying device for particleboard. Background Technology

[0002] Particleboard, as a widely used composite board, is widely used in furniture manufacturing, building decoration, and home furnishing materials due to its advantages such as low cost, easy processing, and uniform density. In its production process, thorough drying is an essential and crucial step. This is not only to ensure the quality of the finished product but also to guarantee the structural stability of the particleboard during long-term use. Insufficiently dried particleboard often contains a high moisture content, which can lead to a series of quality problems during use, such as cracking, warping, and deformation, seriously affecting the physical properties and appearance of the board. Especially in high humidity or dry environments, changes in the internal moisture content of the board can cause dimensional changes, thus affecting its stability and lifespan in furniture or construction. Therefore, proper drying during production not only helps improve the strength and stability of particleboard but also effectively reduces the deformation rate during subsequent processing and use.

[0003] In practice, during the drying process, as the moisture in the particleboard gradually decreases and it shrinks, common clamping devices often fail to stably hold the board, causing it to wobble during drying. In addition, traditional clamping devices are prone to leaving indentations on the particleboard surface, affecting the appearance quality of the finished product. In practice, particleboard drying usually adopts single-channel hot air drying or natural air drying methods, but these methods have significant shortcomings in meeting the needs of large-scale production. Single-channel drying methods are prone to uneven drying, especially since the moisture evaporation rates of the inner and outer layers of the particleboard are different, which can easily cause quality problems such as cracking or warping. At the same time, traditional drying methods have high energy consumption and low efficiency, making it difficult to meet the requirements of high-efficiency and energy-saving production.

[0004] Therefore, a multi-channel drying device for particleboard is proposed to solve the above problems. Summary of the Invention

[0016] This invention provides a multi-channel drying device for particleboard. Compared with the prior art, it has the following advantages: In this invention, an auxiliary drying mechanism is provided. When the user uses the auxiliary drying mechanism, multiple particleboard bodies are passed through multiple limiting slots, and the particleboard bodies are respectively attached to the inner sides of multiple limiting frames. Then, the user can pull the transmission rod, and then rotate the transmission rod, which drives the linkage plate to rotate. The linkage plate has multiple protrusions on its side wall. When the protrusions rotate, they squeeze the pressing rod, which in turn squeezes the clamping frame. The clamping frame can cooperate with the limiting frame to clamp the particleboard bodies. With the help of the set return spring, on the one hand, it can prevent the particleboard bodies from loosening due to shrinkage, thus avoiding shaking during subsequent drying. On the other hand, it can prevent excessive clamping force from damaging the surface of the particleboard bodies, keeping their surface intact. Then, the user can start motor one, the hot air blower body, the multi-channel air duct, and motor two. The output end of motor one drives the lead screw to rotate, and the lead screw drives... The movable support moves along the inner wall of the drying duct. The multi-channel duct is designed with different temperature zones, and the temperature settings of each channel are different. This temperature stratification, combined with the synchronous operation of the screw and the movable support, allows the particleboard to be heated gradually during the drying process. Driven by the screw, the movable support moves the particleboard through the multi-channel duct with different temperatures, gradually transitioning it from the low-temperature zone to the high-temperature zone. This gradual drying process, starting with low temperature and then increasing the temperature, avoids the rapid dehydration and drying stress that may result from a sudden temperature rise. It effectively prevents cracking and warping of the particleboard due to uneven internal moisture, thereby improving the integrity and quality of the product. The output of motor two drives the connecting plate to rotate, causing the particleboard on one side to rotate. The hot air blower can cover the inner sides of multiple particleboard bodies with hot air, avoiding drying dead spots.

[0017] 2. In this invention, through the installation mechanism, the user first starts the motor to make the limiting groove on one side of the locking cover and the through groove on the surface of the sliding cover consistent. When the user needs to install the particleboard body into the inner side of the connecting plate, the user can pass the particleboard body through multiple through grooves. Then, the user ensures that all the particleboard bodies are inside the through grooves. The user can rotate the collar, which drives the closing plate to rotate, so that the closing plate covers multiple through grooves. Then, the user can slide the mounting plate so that the bottom end of the mounting plate is inserted into the mounting groove. Then, the user can start the electric push rod, which drives the sliding cover to move through the mounting plate. The closing plate can squeeze multiple particleboard bodies, so that multiple particleboard bodies fit together with the limiting frame, simplifying the process of installing particleboard bodies. The user only needs to push the particleboard bodies into the through grooves in sequence and rotate the closing plate. No additional tools are required, the operation is convenient, and the work efficiency is significantly improved, making it suitable for batch operations. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1 - Figure 8The present invention provides two technical solutions, specifically including the following embodiments: Example

[0022] A multi-channel drying device for particleboard includes a drying device body 1. A multi-channel air duct 2 is installed on the back of the drying device body 1. A drying pipe 6 is fixedly connected to the inner wall of the drying device body 1. The output end of the multi-channel air duct 2 passes through the top of the inner wall of the drying pipe 6, allowing airflows of different temperatures to be distributed to various areas within the drying pipe 6, forming a multi-channel drying effect. This ensures gradual heating of the particleboard body 7 and effectively prevents cracking or warping during the drying process. An auxiliary drying mechanism 3 is provided inside the drying pipe 6. The auxiliary drying mechanism 3 includes a locking cover 301, a lead screw 302, a limiting support 304, a locking groove 305, a transmission rod 306, a locking plate 307, a motor 308, and a movable support 309. The system includes a second motor 310, a limiting frame 311, a fixing frame 312, a connecting plate 313, a clamping frame 314, a return spring 315, a pressing rod 316, a pressing plate 317, and a linkage plate 318. The output end of the first motor 308 passes through the drying pipe 6 and is fixedly connected to a lead screw 302. Driven by the first motor 308, the lead screw 302 moves the movable support 309 along the inner wall of the drying pipe 6, allowing the particleboard body 7 to gradually pass through various temperature zones, achieving a uniform drying effect. The drying pipe 6 contains four particleboard bodies 7. One end of the lead screw 302 is rotatably connected to a limiting plate 303, the bottom end of which is fixedly connected to the inner wall of the drying pipe 6. The middle of the lead screw 302 is threadedly connected to the movable support 309. The movable support 309... The inner wall of the drying pipe 6 is slidably connected. Multiple connecting rods 12 are fixedly connected to the side wall of the movable support 309. One end of each connecting rod 12 is rotatably connected to a connecting plate 313. A second motor 310 is fixedly connected to the inner side of the movable support 309. The output end of the second motor 310 is fixedly connected to the connecting plate 313. A support plate 9 is fixedly connected to the bottom end of the first motor 308. One end of the support plate 9 is fixedly connected to one side wall of the drying device body 1. A hot air blower body 4 is installed inside the connecting plate 313. Four limiting frames 311 are fixedly connected to the inner side of the connecting plate 313. A locking cover 301 is fixedly connected to one end of each of the four limiting frames 311. Four ventilation slots 10 are provided on the side wall of the locking cover 301. Four ventilation slots are also provided on the side wall of the connecting plate 313. The locking cover 301 and the connecting plate 313 both have ventilation grooves 10 and 21 on their side walls to ensure smooth airflow during the drying process, improve drying efficiency, prevent moisture accumulation in the enclosed space, and further ensure drying uniformity. The locking cover 301 has four limiting grooves 8 on its outer side, through which the four particleboard bodies 7 pass. A limiting support 304 is fixedly connected to the outer side of the locking cover 301. A locking groove 305 is provided on the outer side of the limiting support 304. A transmission rod 306 is slidably connected to the middle of the limiting support 304. A locking plate 307 is fixedly connected to one end of the transmission rod 306, and the size of the locking plate 307 matches the locking groove 305. A linkage plate 318 is slidably connected to the other end of the transmission rod 306.The linkage plate 318 is rotatably connected to the inner side of the locking cover 301. Four fixing frames 312 are fixedly connected to the inner side of the locking cover 301. A pressing rod 316 is fixedly connected to one side wall of each of the four fixing frames 312. One end of each of the four fixing frames 312 is fixedly connected to the inner side of the connecting plate 313. A return spring 315 is fixedly connected to the inner side of each of the four fixing frames 312. One end of each of the four return springs 315 is fixedly connected to a clamping frame 314. The clamping frame 314 cooperates with the return spring 315 to achieve flexible clamping of the particleboard body 7. The return spring 315 allows for... A slight elastic adjustment is allowed to accommodate the shrinkage of the particleboard body 7 during the drying process, ensuring it remains tightly fitted to the limiting frame 311 to prevent wobbling and avoid indentations during clamping, thus protecting the surface integrity of the board. The two ends of the four clamping frames 314 are slidably connected to the inner sides of the locking cover 301 and the connecting plate 313, respectively. One end of the extrusion rod 316 is fixedly connected to the extrusion plate 317, which is attached to the side wall of the linkage plate 318. The inner sides of the clamping frames 314 and the limiting frames 311 are respectively attached to the outer and inner sides of the particleboard body 7.

[0023] During operation, when the user uses the auxiliary drying mechanism 3, the user passes multiple particleboard bodies 7 through multiple limiting slots 8, and the multiple particleboard bodies 7 are respectively attached to the inner sides of multiple limiting frames 311. Then, the user can pull the transmission rod 306, and then rotate the transmission rod 306, which drives the linkage plate 318 to rotate. The linkage plate 318 has multiple protrusions on its side wall. When the protrusions rotate, they squeeze the pressing rod 316, and the pressing rod 316 squeezes the clamping frame 314. The clamping frame 314 can cooperate with the limiting frame 311 to clamp the particleboard bodies 7. With the help of the set return spring 315, on the one hand, it can prevent the particleboard bodies 7 from loosening due to shrinkage, thus avoiding shaking during subsequent drying. On the other hand, it can prevent excessive clamping force from damaging the surface of the particleboard bodies 7, keeping its surface intact. Then, the user can start the motor 1 308, the hot air blower body 4, the multi-channel air duct 2, and the motor 2 310. The output end of the motor 1 308 drives the lead screw 302 to rotate. Rod 302 drives the movable support 309 to move along the inner wall of the drying duct 6. The multi-channel air duct 2 is designed with different temperature zones, and the temperature settings of the multi-channel air duct 2 are different. This temperature stratification, combined with the synchronous operation of the screw 302 and the movable support 309, allows the particleboard body 7 to be heated in a gradual manner during the drying process. Driven by the screw 302, the movable support 309 drives the particleboard to gradually pass through the multi-channel air duct 2 with different temperatures, so that it gradually transitions from the low temperature zone to the high temperature zone. Through the gradual drying of low temperature first and then high temperature, the rapid dehydration and drying stress that may be caused by a sudden increase in temperature are avoided, and the cracking and warping problems of the particleboard body 7 due to uneven internal moisture are effectively prevented, thereby improving the integrity and quality of the product. The output end of motor 310 drives the connecting plate 313 to rotate. The connecting plate 313 causes the particleboard body 7 on one side to rotate. The hot air blower body 4 can cover the inner side of multiple particleboard bodies 7 with hot air to avoid drying dead corners. Example

The installation mechanism 5 includes an installation plate 501, a slide rail 502, an electric push rod 503, a slot 504, a through groove 505, a sealing plate 506, a collar 507, a sliding cover 509, and a through groove 508. The bottom end of the electric push rod 503 is fixedly connected to the top end of the drying device body 1. The output end of the electric push rod 503 is vertically slidably connected to the installation plate 501. There is a large damping at the sliding connection between the installation plate 501 and the electric push rod 503, so it will not change unless manually pushed. One end of each of the two slide rails 502 is... A sliding cover 509 is slidably connected between two slide rails 502 and fixedly connected to one end of the drying pipe 6. A through groove 508 is provided on the front side of the sliding cover 509, and four through slots 505 are provided on the front side of the sliding cover 509. The size of the through slots 505 matches the size of the particleboard body 7. Four sealing plates 506 are rotatably connected to the outer wall of the sliding cover 509. A collar 507 is fixedly connected to the outer wall of the four sealing plates 506. The collar 507 is used to drive the four sealing plates to rotate. A slot 504 is provided at the top of the sliding cover 509, and the bottom end of the mounting plate 501 is inserted into the inner wall of the slot 504.

[0025] The user first starts motor 310, aligning the limiting groove 8 on one side of locking cover 301 with the through groove 505 on the surface of sliding cover 509. When the user needs to insert the particleboard body 7 into the inner side of connecting plate 313, the user can pass the particleboard body 7 through multiple through grooves 505. The user then ensures that all particleboard bodies 7 are inside the inner wall of the through grooves 505. The user can then rotate collar 507, which in turn rotates closing plate 506, covering multiple through grooves 505. The user can then slide the device in place. The mounting plate 501 is inserted into the mounting groove. Then, the user can activate the electric push rod 503, which drives the sliding cover 509 to move through the mounting plate 501. The closing plate 506 can squeeze multiple particleboard bodies 7, so that multiple particleboard bodies 7 fit together with the limiting frame 311, which simplifies the process of loading particleboard bodies 7. The user only needs to push the particleboard bodies 7 into the through groove 505 in sequence and rotate the closing plate 506. No additional tools are required, the operation is convenient, and the work efficiency is significantly improved, making it suitable for batch operations.
