Description

Technical Field

[0001] This invention relates to the field of particleboard technology, and more specifically, to a particleboard laying device capable of removing bent wood chips. Background Technology

[0002] During the operation of a particleboard production line, material enters the feeding device from the metering device. The material falls onto the screen roller below via the throwing roller, and then passes through the screen roller into the cage roller below to complete the feeding process. However, during feeding, some bent particleboard shavings cannot be discharged and enter the cage roller below, causing warping of the board surface and affecting the surface flatness of the board. Currently, there is no effective solution to this problem in the industry. Summary of the Invention

[0003] This invention proposes a particleboard laying device that can remove bent wood shavings, solving the problem in related technologies where bent wood shavings cannot be discharged during the particleboard production process, affecting the quality of the finished product.

[0004] The technical solution of the present invention is as follows:

[0005] A particleboard installation device capable of removing bent wood chips, including

[0006] Screening rollers, wherein several screening rollers are arranged sequentially.

[0007] A rejection disc is disposed on the rejection screen roller. Several rejection discs are arranged sequentially along the axial direction of the rejection screen roller, forming a rejection gap between two adjacent rejection discs. Each rejection disc extends into the rejection gap on another adjacent rejection screen roller. Each rejection disc has one or more rejection notches, which are arranged circumferentially on the circumference of the rejection disc when there are multiple notches.

[0008] The rejection roller includes:

[0009] A rotating roller is rotatably mounted on a frame, and the outer wall of the rotating roller has a first guide groove along the axial direction of the rotating roller.

[0017] A fine screening roller is rotatably mounted on the frame. Several fine screening rollers are arranged in a row. The fine screening rollers and the waste discharge component are respectively located on both sides of the rejection roller. The throwing roller is located above the fine screening roller and the rejection roller.

[0018] As a further technical solution, the surface of the throwing roller has throwing blades, which are plate-shaped or cylindrical and arranged in several circles. When the throwing roller rotates, the throwing blades on two throwing rollers abut against each other or cancel the abutment. The surface of the fine screening roller is evenly distributed with several prismatic protrusions, which are used for the falling of wood shavings between two adjacent fine screening rollers.

[0019] As a further technical solution, it also includes

[0020] A squirrel cage roller is rotatably mounted on the frame. Several squirrel cage rollers are arranged in an array, and the squirrel cage rollers are located below the fine screening roller and the rejecting screening roller.

[0021] A conveyor belt, positioned below the squirrel cage roller, is used to collect the wood shavings falling from the squirrel cage roller.

[0022] A material feeding box is mounted on the frame and has a material discharge port at its bottom. The material throwing rollers are arranged in a series of inclined sections at the material discharge port.

[0023] The hood body, the sieve roller, the waste discharge component, the guide plate, the throwing roller, the fine sieve roller, the squirrel cage roller and the paving box are all arranged inside the hood body.

[0024] As a further technical solution, the cover has a feed inlet located above the paving box.

[0025] As a further technical solution, the material rejection notches on two adjacent rejection rollers are symmetrically arranged.

[0026] As a further technical solution, the rejecting plate has a second guide groove along the circumference of the rejecting plate, and also includes...

[0027] A sliding piece is slidably disposed within the second guide groove and extends into the material rejection notch; the sliding piece has a hook portion.

[0028] An elastic element, one end of which acts on the bottom of the second guide groove and the other end of which acts on the slider, provides a force to the slider as it approaches the bottom of the second guide groove.

[0029] As a further technical solution, the outer wall of the roller has a baffle plate, the baffle plate is located within the rejection interval and is coplanar with the rejection piece within the same rejection interval, the baffle plate has a protrusion, and the end of the rejection piece within the same rejection interval is located within the protrusion.

[0030] As a further technical solution, the outer wall of the roller has a reciprocating groove, and also includes...

[0031] A guide member is mounted on the frame and slides within the reciprocating groove.

[0032] An isolation sleeve is disposed on one side of the roller, and the isolation sleeve has a telescopic part that abuts against the frame.

[0033] The working principle and beneficial effects of this invention are as follows:

[0034] This invention incorporates a sieving roller system. The core component for removing bent wood shavings consists of several sequentially arranged sieving rollers, forming a continuous removal system. The arrangement of each sieving roller ensures that material passes continuously and evenly through the entire removal process. The sieving rollers are driven by chains, resulting in a simple structure that is not easily damaged. Each sieving roller has several scraping blades arranged axially along its axis, forming a series of orderly scraping intervals. The scraping blades on adjacent sieving rollers are staggered, and together with corresponding scraping blades on adjacent rollers, they form scraping intervals—a crucial screening area. Each scraping blade has one or more scraping notches. When there are multiple notches, they are arranged circumferentially along the blade. This design precisely "captures" and removes bent or non-compliant wood shavings. The principle of removing bent wood shavings is that, during operation, the raw material wood shavings pass through the scraping intervals as the sieving rollers rotate. Because of the notches, bent shavings that do not meet the size or shape requirements cannot pass through smoothly and are effectively intercepted and removed from the rejecting process. Straight, appropriately sized shavings, however, can pass through smoothly and continue to the next stage. Simultaneously, the notches allow bent shavings to be smoothly passed through sequentially by the rotating rejecting blades driven by the chain, ensuring the smooth discharge of rejected material. In summary, this device, through its precise rejecting blade design and ingenious arrangement of the rejecting intervals, achieves highly efficient screening of shavings, removing bent shavings that affect the quality of the finished product. This provides higher-quality raw materials for subsequent particleboard pressing processes, thereby improving the quality of the final product and production efficiency.

[0035] The screen rollers consist of rotating rollers and sleeve rollers. The rotating rollers are designed to be mounted on the frame and rotate freely. Multiple rotating rollers are driven by the same chain and a single drive unit. The outer wall of the rotating roller has a first guide groove extending axially. This design provides a precise sliding track for the sleeve roller, which is fitted over the rotating roller, ensuring its stability and guidance during rotation. The sleeve roller, acting as an outer casing for the rotating roller, is fitted around its perimeter, and its inner wall is equipped with guide sections that match the first guide groove on the outer wall of the rotating roller. This design allows the sleeve roller to slide smoothly along the first guide groove of the rotating roller, ensuring both dynamic adjustment capability and precise control of the chipper position under different operating conditions. Several chippers are fixedly mounted on the outer wall of the sleeve roller, arranged circumferentially along the sleeve roller, forming a crucial contact surface for removing bent shavings. Because the sleeve roller can slide along the first guide groove on the rotating roller, the depth or position of the shavings passing through the gap between the scraper and the sleeve roller can be changed by adjusting the position of the sleeve roller, thereby preventing bent shavings from falling below the scraper notch. In summary, this design, through the combination of the rotating roller and the sleeve roller, and especially the precise fit between the first guide groove and the guide section, not only achieves flexible adjustment of the scraper position but also improves the accuracy and adaptability of the entire scraping process. It provides an efficient and adjustable mechanical device for scraping bent shavings, making the scraping of bent shavings more accurate and efficient. Attached Figure Description

[0048] Reference Figures 1-6 As an embodiment of the present invention, a particleboard laying device capable of removing bent wood shavings is proposed, comprising:

[0049] Screening roller 1, and several screening rollers 1 are arranged sequentially.

[0050] The material removal plates 2 are disposed on the material removal roller 1. There are several material removal plates 2 arranged sequentially along the axial direction of the material removal roller 1. A material removal interval 201 is formed between two adjacent material removal plates 2. The material removal plates 2 extend into the material removal interval 201 on another adjacent material removal roller 1. The material removal plates 2 have one or more material removal notches 202. When there are multiple notches 202, they are arranged circumferentially around the circumference of the material removal plates 2.

[0051] The screening roller 1 includes a rotating roller 101, which is rotatably mounted on the frame 3. The outer wall of the rotating roller 101 has a first guide groove 102 along the axial direction of the rotating roller 101.

[0052] A sleeve roller 103 is sleeved around the rotating roller 101. The inner wall of the sleeve roller 103 has a guide portion 104, which is slidably disposed within a first guide groove 102. The outer wall of the sleeve roller 103 has a scraper 2.

[0053] This embodiment features a rejection roller 1. The core component for removing bent wood shavings consists of several sequentially arranged rejection rollers 1, forming a continuous rejection system. The arrangement of each rejection roller 1 ensures that the material passes through the entire rejection process continuously and evenly. The rejection roller 1 is driven by a chain, resulting in a simple structure that is not easily damaged. Each rejection roller 1 has several rejection blades 2, arranged axially along the roller 1 to form a series of ordered rejection intervals 201. The rejection blades 2 on adjacent rejection rollers 1 are staggered, and together with their corresponding counterparts on the same adjacent rejection roller 1, they form the rejection interval 201, a crucial screening area. Each rejection blade 2 has one or more rejection notches 202. When there are multiple notches, they are arranged circumferentially along the blade 2. This design is intended to precisely "capture" and reject bent or non-compliant wood shavings. The principle behind removing bent wood shavings is as follows: During operation, raw wood shavings rotate with the screening roller 1, passing through various screening intervals 201. Due to the presence of screening gaps 202, bent wood shavings that do not meet the size or shape requirements cannot pass smoothly through these gaps and are thus effectively intercepted and removed from the screening process. Straight wood shavings of the appropriate size can pass smoothly and continue to the next process. Simultaneously, the design of the screening gaps 202 allows bent wood shavings to be smoothly passed sequentially through the screening gaps 202 under the rotation of the screening blades 2 driven by the chain, ensuring that the rejected material is discharged smoothly. In summary, this device, through the precise design of the screening blades 2 and the ingenious layout of the screening intervals 201, achieves efficient screening of wood shavings, removes bent wood shavings that affect the quality of the finished product, provides higher-quality raw materials for the subsequent particleboard pressing process, and thus improves the quality of the final product and production efficiency.

[0054] The screening roller 1 includes a rotating roller 101 and a sleeve roller 103. The rotating roller 101 is designed to be mounted on the frame 3 and can rotate freely. Multiple rotating rollers 101 are driven by the same chain and a single drive unit. A first guide groove 102 extending axially is provided on the outer wall of the rotating roller 101. This design provides a precise sliding track for the sleeve roller 103, which is fitted over the rotating roller 101, ensuring the stability and guidance of the sleeve roller 103 during rotation. The sleeve roller 103, as the outer casing of the rotating roller 101, is fitted around the rotating roller 101, and its inner wall is equipped with a guide portion 104 that matches the first guide groove 102 on the outer wall of the rotating roller 101. This design allows the sleeve roller 103 to slide smoothly along the first guide groove 102 of the rotating roller 101, ensuring both the dynamic adjustment capability of the sleeve roller 103 and the precise control of the position of the screening disc 2 under different working conditions. A number of scraping blades 2 are fixedly mounted on the outer wall of the sleeve roller 103. These scraping blades 2 are arranged circumferentially along the sleeve roller 103, forming a key contact surface for removing bent shavings. Since the sleeve roller 103 can slide along the first guide groove 102 on the rotating roller 101, the depth or position of the shavings passing through the gap between the scraping blades 2 and the sleeve roller 103 can be changed by adjusting the position of the sleeve roller 103, thereby preventing bent shavings from falling below the scraping notch 202. In summary, this design, through the combination of the rotating roller 101 and the sleeve roller 103, especially the precise cooperation between the first guide groove 102 and the guide part 104, not only achieves flexible adjustment of the position of the scraping blades 2, but also improves the accuracy and adaptability of the entire scraping process, providing an efficient and adjustable mechanical device for removing bent shavings, making the removal of bent shavings more accurate and efficient.

[0055] Furthermore, the frame 3, the screen roller 1 is rotatably mounted on the frame 3, the waste discharge component 4 is mounted on the frame 3 and located on one side of the screen roller 1, one end of the guide plate 5 is mounted on the waste discharge component 4, and the other end extends into the material removal interval 201 and gradually rises to approach the screen roller 1.

[0056] In this embodiment, a frame 3 is designed, and the entire rejection device is mounted on a stable frame 3. The frame 3 provides a reliable support platform for the rejection roller 1, ensuring the stability and precise alignment of all components during continuous operation. The waste discharge component 4 is located on the frame 3, adjacent to one side of the rejection roller 1. Its main function is to collect and discharge defective wood shavings, such as bent or non-standard sized shavings, rejected from the rejection interval 201, ensuring the continuity of the production process and a clean working environment. The guide plate 5 is an important auxiliary component in the device. One end is fixed to the waste discharge component 4, and the other end extends into the rejection interval 201, designed to gradually slope upwards towards the rejection roller 1. The ingenuity of this design lies in the fact that the guide plate 5 not only helps guide the wood shavings smoothly through the rejection interval 201, but also, through its gradually rising structure, further promotes the natural sliding of defective wood shavings into the waste discharge component 4, improving rejection efficiency and accuracy. The angle and position of the guide plate 5 are rationally designed to effectively prevent qualified wood shavings from being mistakenly rejected, while ensuring a highly efficient and smooth rejection process. Through these designs, the device not only achieves effective rejection of bent wood shavings, but also further optimizes the rejection process through the ingenious layout of the guide plate 5, reducing material waste and improving production efficiency and product quality. It is an indispensable and highly efficient rejection device on modern particleboard production lines.

[0057] Furthermore, it also includes a throwing roller 6, which is rotatably mounted on the frame 3 and consists of several rollers arranged in a series of inclined positions. A fine screening roller 7 is also rotatably mounted on the frame 3 and consists of several rollers arranged in a series. The fine screening roller 7 and the waste discharge component 4 are respectively located on both sides of the rejection roller 1. The throwing roller 6 is located above the fine screening roller 7 and the rejection roller 1.

[0058] In this embodiment, several throwing rollers 6 are arranged at an angle in sequence. These throwing rollers 6 are also mounted on the frame 3 and located above the rejecting roller 1 and the fine screening roller 7. The angled arrangement of the throwing rollers 6 helps to evenly disperse and transfer materials at different stages, improving processing efficiency. The fine screening rollers 7 are also arranged in several rows on the frame 3, and are positioned on both sides of the rejecting roller 1, along with the waste discharge component 4. The function of the fine screening rollers 7 is to perform more detailed grading and screening of the wood shavings after the initial screening, separating the smaller, finer wood shavings and sending them to the conveyor belt as the surface layer of the particleboard, ensuring the surface quality of the wood shavings. In summary, the addition of the throwing rollers 6 and the fine screening rollers 7 not only optimizes the flow path of the material in the rejecting device for bent wood shavings, but also further refines the screening and grading process. The throwing rollers 6, with their inclined arrangement, effectively promote the flow and distribution of materials, while the fine screening rollers 7 perform secondary processing on the materials screened by the rejecting rollers 1, ensuring the purity and dimensional consistency of the wood chips that finally enter the production process. This is crucial for improving the quality of the finished particleboard. This series of designs together create an efficient and precise wood chip processing system, which is more suitable for large-scale, high-requirement particleboard production environments.

[0059] Furthermore, the surface of the throwing roller 6 has throwing plates 601, which are plate-shaped or cylindrical and arranged in several circles. When the throwing roller 6 rotates, the throwing plates 601 on the two throwing rollers 6 abut against each other or cancel the abutment. The surface of the fine screening roller 7 has several prismatic protrusions evenly distributed, which are used for the falling of wood shavings between two adjacent fine screening rollers 7.

[0060] In this embodiment, the surface of the throwing roller 6 is equipped with several plate-shaped throwing blades 601, which are evenly arranged along the circumference of the throwing roller 6. When the throwing roller 6 rotates, the throwing blades 601 on adjacent throwing rollers 6 abut against each other or separate. This design can effectively stir and disperse the fed wood shavings, ensuring uniform material distribution, avoiding stacking and clogging, and improving the uniformity and efficiency of subsequent screening. The plate-shaped throwing blades 601 of the throwing roller 6 can also be cylindrical to achieve material dispersion. The surface of the fine screening roller 7 is specially designed with several prismatic protrusions, which are evenly distributed on the surface of the fine screening roller 7. The prismatic protrusions not only increase the contact area with the material, helping to more thoroughly screen and separate smaller wood shavings, but also form a channel in the gap between two adjacent fine screening rollers 7, allowing qualified wood shavings to fall smoothly, while fine wood shavings are further screened out in this process, thereby improving the quality of the surface and core layers of the particleboard. In summary, the addition of these design details enables the entire device for removing bent wood chips to more precisely control the material flow during the processing, improve the screening accuracy, and ensure that the wood chips can pass through layers of screening and enter the next stage of the production process. This is of great significance for improving the final quality and production efficiency of particleboard.

[0061] Furthermore, it also includes a squirrel cage roller 8, which is rotatably mounted on the frame 3. Several squirrel cage rollers 8 are arranged in a row, and the squirrel cage rollers 8 are located below the fine screen roller 7 and the rejection screen roller 1.

[0062] In this embodiment, a squirrel-cage roller 8 is designed. Several squirrel-cage rollers 8 are added to the device, and these rollers 8 are also designed to rotate on the frame 3, but they are located below the fine screening roller 7 and the rejection screening roller 1. This layout indicates that the squirrel-cage rollers 8 undertake the subsequent sorting and conveying tasks in the material handling process. The name "squirrel-cage roller 8" comes from its structural characteristics. Typically, these rollers have a grid or protrusion structure similar to a cage on their surface, which can perform final sorting and guiding of the wood shavings after being screened by the fine screening roller 7. During rotation, the squirrel-cage roller 8 can effectively further comb and even out the qualified wood shavings below the fine screening roller 7, while removing any small impurities that may remain, ensuring the quality of the wood shavings entering the next process. The addition of the squirrel-cage roller 8 makes the entire process of removing bent wood shavings more complete and efficient. From the initial rejection of bent wood shavings by the rejection screening roller 1, to the further screening by the fine screening roller 7, and then to the final sorting by the squirrel-cage roller 8, each step is designed to improve the accuracy and efficiency of material handling, reduce waste, and ensure a high-quality supply of raw materials in the particleboard production process. In summary, the introduction of the squirrel cage roller 8 not only complements the function of the device for removing bent shavings, but also improves the automation level and production efficiency of the entire production line, making it one of the key links in ensuring the quality of finished particleboard products.

[0063] Furthermore, it also includes a conveyor belt, which is located below the squirrel cage roller 8 to catch the wood shavings falling from the squirrel cage roller 8.

[0064] In this embodiment, a conveyor belt is designed and installed below the device, positioned directly beneath the cage roller 8. The purpose of this design is to efficiently and smoothly receive the qualified wood shavings falling from the cage roller 8, ensuring a continuous flow of material to subsequent processing stages. The use of the conveyor belt makes the entire process of removing bent wood shavings more automated and continuous. After multiple processes including sieving, screening, and cage sorting, the qualified wood shavings fall naturally onto the conveyor belt by gravity. The conveyor belt then starts, transporting these wood shavings to the next process, such as drying, mixing, and hot pressing, without manual intervention, greatly improving production efficiency and reducing labor intensity. The addition of the conveyor belt, together with the previous sieving roller 1, fine sieving roller 7, and cage roller 8, forms a tightly connected work chain. Each link is closely connected, not only optimizing the smoothness of material flow but also ensuring the efficiency and accuracy of removing bent wood shavings, laying a solid foundation for the production of high-quality particleboard. In summary, the integration of the conveyor belt not only improves the material transport system of the entire device for removing bent shavings, but also promotes the overall automation level of the production line, ensuring the continuity and efficiency of the production process.

[0065] Furthermore, it also includes a paving box 9, which is set on the frame 3 and has a material discharge port 901 at the bottom. The throwing rollers 6 are arranged in sequence at the material discharge port 901.

[0066] In this embodiment, a piling box 9 is designed and installed on the frame 3, with a material discharge port 901 at its bottom. The function of the piling box 9 is to collect the raw materials discharged from the screening process. The design of the piling box 9 improves the environment during the particleboard piling process, which is beneficial to improving the working environment for workers and protecting their health.

[0067] Furthermore, it also includes a cover 10, and the screening roller 1, waste discharge component 4, guide plate 5, throwing roller 6, fine screening roller 7, squirrel cage roller 8 and laying box 9 are all set inside the cover 10.

[0068] In this embodiment, a cover 10 is designed to make the entire particleboard laying device capable of removing bent wood shavings more enclosed, safer, and easier to maintain. Specific features are as follows: Cover 10 enclosure: As a closed structure, cover 10 encloses all key components, including the sieving roller 1, waste discharge component 4, guide plate 5, throwing roller 6, fine sieving roller 7, squirrel cage roller 8, and laying box 9. This design has several important functions: Safety protection: The presence of cover 10 effectively isolates the high-speed rotating mechanical parts from the external environment, preventing operators from coming into contact with rotating parts during production, reducing safety hazards, and ensuring production safety. Dust control: During the wood shavings processing, a certain amount of wood chips and dust are generated. Cover 10 can significantly reduce the diffusion of these particulate matter, helping to maintain a clean workshop environment. Combined with a dust removal system that may be installed, it further improves the quality of the working environment. Noise suppression: The enclosed cover 10 also helps reduce the noise generated by the equipment operation, providing workers with a relatively quiet working environment, meeting the environmental protection and employee health requirements of modern factories. Ease of maintenance: The enclosure 10 is typically designed with easy opening and closing, facilitating regular equipment inspection, cleaning, and maintenance, thus ensuring production efficiency and long-term stable equipment operation. In summary, the integration of the enclosure 10 not only enhances the safety and environmental friendliness of production operations but also facilitates equipment maintenance and management. It is an indispensable part of modern production lines, ensuring the efficient, safe, and sustainable operation of particleboard laying devices that can remove bent wood chips.

[0069] Furthermore, the cover 10 has a feed inlet 1001, which is located above the paving box 9.

[0070] In this embodiment, the cover 10 is provided with a feed inlet 1001, and this feed inlet 1001 is deliberately arranged directly above the spreading box 9. This design ensures that the raw material wood shavings can be directly fed into the feed inlet 1001 and smoothly enter the entire processing system.

[0071] Furthermore, the material rejection notches 202 on the two adjacent rejection rollers 1 are symmetrically arranged.

[0072] In this embodiment, the symmetrically arranged rejection gaps 202 ensure that the shavings are treated with a consistent screening standard regardless of the angle from which they pass through the rejection roller 1. This symmetrical design reduces uneven screening caused by positional deviations, ensuring the accuracy and consistency of rejecting bent shavings. The symmetrical layout allows the shavings passing through the rejection gap 201 to be evenly stressed, avoiding material damage or screening errors caused by uneven stress, thereby improving the efficiency and effectiveness of the rejection process. The symmetrical design enhances the stability of the entire rejection system mechanically, reduces vibration and noise during operation, extends the service life of the equipment, and improves the comfort of the production environment. When adjustments or maintenance of the rejection gap are required, the symmetrical layout simplifies the operation process, as only one rejection gap 202 needs to be adjusted to ensure the consistency of the overall screening standard, reducing maintenance costs and complexity. In summary, the symmetrical arrangement of the material removal notches 202 on two adjacent material removal rollers 1 not only optimizes the efficiency and accuracy of removing bent wood chips, but also improves the overall stability and ease of operation of the equipment. It is one of the key elements for achieving efficient and high-quality particleboard production.

[0073] Furthermore, the scraper 2 has a second guide groove 203 along the circumference of the scraper 2, and also includes a slider 204. The slider 204 is slidably disposed in the second guide groove 203 and extends into the scraper notch 202. The slider 204 has a hook portion. One end of the elastic member 205 acts on the bottom of the second guide groove 203, and the other end acts on the slider 204, providing a force for the slider 204 to approach the bottom of the second guide groove 203.

[0074] In this embodiment, the scraper 2 is designed with a second guide groove 203. Each scraper 2 has not only a scraping notch 202 on its outer edge, but also an additional second guide groove 203 extending circumferentially. This design not only provides a track for the installation and adjustment of the slider 204, but also makes the structure of the scraper 2 more complex and functionally richer. The slider 204 is designed to be slidably disposed within the second guide groove 203 of the scraper 2, and one end of it can extend into the scraping notch 202. The presence of the slider 204 allows the device to control the scraping process more precisely, especially through the hook on the slider 204, which can further improve the efficiency and accuracy of scraping bent shavings. One end of the elastic element 205 is fixed to the bottom of the second guide groove 203, and the other end is connected to the slider 204. The tension of the elastic element 205 provides a pulling force to the slider 204 towards the bottom of the second guide groove 203. This design ensures that when the rejecting disc 2 rotates during the rejection process, the slider 204 automatically resets after moving away from the bottom of the second guide groove 203 under centrifugal force. Even when subjected to material impact or vibration, it quickly returns to the set position, maintaining effective contact between the rejecting disc 2 and the material. This avoids problems such as decreased rejection efficiency or incomplete rejection caused by loosening. In summary, this innovative design, through the combination of the slider 204 and the elastic element 205, not only achieves dynamic adjustment of the rejecting disc 2's function but also improves the automation level and adaptability of the rejection process, ensuring rejection accuracy and stability in continuous operation. It is key to improving the overall equipment performance.

[0075] Furthermore, the outer wall of the roller 103 has a baffle plate 105, which is located within the rejection interval 201 and is coplanar with the rejection piece 2 within the same rejection interval 201.

[0076] In this embodiment, baffle plates 105 are designed, with a baffle plate 105 installed on the outer wall of each roller 103. These baffle plates 105 are placed inside each rejection interval 201. This layout ensures that the baffle plate 105 and the rejection blade 2 within the rejection interval 201 remain coplanar, forming a continuous and flat screening interface. The presence of the baffle plate 105 not only expands the screening contact area for the wood shavings but also, through its cooperative work with the rejection blade 2, effectively blocks unqualified curved wood shavings from passing through, ensuring that only straight, compliant wood shavings can pass smoothly, thereby improving the accuracy and efficiency of screening. The design of the baffle plate 105 and roller 103 makes the entire rejection screening structure more compact, reduces the assembly difficulty of individual components, and also facilitates overall installation and adjustment, enhancing the stability of the device. To reduce the probability of missed detections, the coplanar design of the baffle plate 105 and the rejecting blade 2 effectively reduces missed detections during the rejection process. Even at high speeds, it ensures the continuity and integrity of the screening process, preventing bent particleboard from mixing with qualified materials, thereby improving the quality of the final particleboard product. In summary, the addition of the baffle plate 105 is another innovative design aimed at improving screening accuracy and efficiency. Together with the rejecting blade 2, it forms a more robust screening barrier, ensuring efficient and stable production and the superior performance of the finished particleboard.

[0077] Furthermore, the baffle plate 105 has a protrusion 106, and the end of the scraper 2 within the same scraper interval 201 is located within the protrusion 106.

[0078] In this embodiment, each baffle plate 105 is designed with a specific protrusion 106. This design is not only to accommodate the structure of the rejecting blade 2, but also to achieve a small gap between the blade and the rejecting blade 2. By extending the end of the rejecting blade 2 within the same rejecting interval 201 to the protrusion 106 side of the baffle plate 105, a small gap between the two is ensured, forming a continuous screening surface. The tight fit between the protrusion 106 and the end of the rejecting blade 2 enhances the overall structural stability of the baffle plate 105 and the rejecting blade 2. Even under high-speed operation or high pressure, it can maintain good positioning, avoiding misalignment or detachment caused by vibration or impact, and ensuring the continuity and accuracy of the screening process. Through this design, the baffle plate 105 and the rejecting blade 2 together form a more precise screening mechanism, which can more accurately identify and remove bent or unqualified shavings, reduce false rejection or missed rejection, and thus improve the accuracy and efficiency of screening. Optimized material flow: The design of protrusion 106 also considers the hydrodynamic characteristics of the material during passage, helping to reduce the resistance of the material when passing through the rejection interval 201, making the material flow smoother and avoiding accumulation or blockage caused by excessive resistance. In summary, the protrusion 106 design of the baffle plate 105 not only enhances the structural stability of the device, but also significantly improves the accuracy and efficiency of screening, making it one of the key designs for achieving high-quality particleboard production.

[0079] Furthermore, the outer wall of the roller 103 has a reciprocating groove 107 and also includes a guide 108, which is disposed on the frame 3 and slides within the reciprocating groove 107.

[0080] In this embodiment, the outer wall of the roller 103 is designed with a reciprocating groove 107 and a guide member 108, further enhancing the adjustment flexibility and precise control capability of the device. The reciprocating groove 107 on the outer wall of the roller 103 provides a precise track for the sliding of the guide member 108. This design allows the roller 103 to be finely adjusted along its axial direction without affecting the overall rotation function, making it possible to adjust the position of the scraper 2. The guide member 108 is mounted on the frame 3 and can slide along the reciprocating groove 107 on the outer wall of the roller 103. The sliding of the guide member 108 not only limits the sliding range of the roller 103, but also, through precise positioning control, allows for fine adjustment of the distance between the scraper 2 and the baffle plate 105, thereby reducing the possibility of the shavings getting stuck due to accidental obstruction. By adjusting the position of the guide component 108, the equipment can maintain optimal working condition during the removal of bent wood shavings by the scraper blade 2. This reduces the obstruction of the wood shavings, minimizing accidental or missed removal and improving screening accuracy and efficiency, thus ensuring material quality in subsequent particleboard manufacturing processes. In summary, by adding a reciprocating groove 107 to the outer wall of the roller 103 and coordinating with the sliding design of the guide component 108, this device significantly improves adjustment flexibility and control precision while maintaining its original function of removing bent wood shavings, providing crucial technical support for achieving high-quality particleboard production.

[0081] Furthermore, it also includes an isolation sleeve 11, which is disposed on one side of the roller 103. The isolation sleeve 11 has a telescopic part, which is abutted against the frame 3.

[0082] In this embodiment, an isolation sleeve 11 is designed and installed on one side of the roller 103. The isolation sleeve 11 is designed to provide an additional protective layer to prevent external impurities or foreign objects from entering the working area of ​​the roller 103 and the rejecting blade 2. It can also reduce the contamination of the machine's interior by dust, debris, etc., thereby extending the service life of the equipment. The isolation sleeve 11 is designed with a telescopic part that can abut against the frame 3. The existence of the telescopic part allows the isolation sleeve 11 to adapt to the slight displacement of the roller 103 during operation or the dimensional changes caused by temperature changes, maintaining good sealing performance. It also facilitates the installation and maintenance of the equipment, ensuring that the isolation sleeve 11 always fits tightly and effectively isolates external interference. Improved working stability: The use of the isolation sleeve 11 can reduce the impact of external factors on the process of rejecting bent shavings, ensuring the stability and screening accuracy of the rejection process. The flexibility of the telescopic part allows the entire device to maintain a good working condition even in the face of changing working conditions during long-term operation, reducing the failure rate and improving the overall operating efficiency. The design of the isolation sleeve 11 simplifies the daily cleaning and maintenance of the equipment because it can be easily disassembled, facilitating the inspection and cleaning of internal components. It also protects core components from damage, reducing maintenance costs. In summary, the isolation sleeve 11 and the telescopic section ensure the internal cleanliness of the bending shavings removal device, reduce wear, and improve the stability and operational efficiency of the equipment. This is an effective design for enhancing production efficiency and ease of maintenance.
