Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of shaving board, in particular to a surface layer paving equipment capable of accurately and uniformly paving materials in transverse direction. BACKGROUND

[0002] At present, in the paving of OSB oriented shaving board, long strip-shaped large shavings are used to realize the paving of upper and lower surface layers, and small shavings (broken shavings) are used to realize the paving of core layer; in this case, the longitudinal material is often more than the transverse material, so that the transverse and longitudinal strength of the board blank has a large difference, therefore, the industry will increase the transverse directional roller paving on the basis of the longitudinal directional arrangement of the surface layer paving to ensure that the transverse and longitudinal strength of the board blank is close to each other. However, at the same time, the transverse directional roller is driven by an independent motor, and the speed of the transverse directional roller has no relationship with the running speed of the board blank, so when the running speed of the board blank changes, it is difficult to adjust the speed of the transverse directional roller to match the running speed of the board blank, resulting in that the belt repeatedly receives materials and stacks materials at some places during the running process, and there are few or even no materials at some places, which produces the phenomenon of gully and hill, so that the transverse paving is not uniform, which affects the quality of the board blank to different degrees, and the existence of curved shavings makes the surface of the finished product prone to appear convex texture, which has been a difficult problem in the industry.

[0030] The working principle and beneficial effects of the present invention are:

[0031] The present application designs a case as the framework of the whole device, which provides a stable support platform to ensure the stable installation and efficient operation of all components, and facilitates the overall movement and maintenance of the device. Pin roller: a plurality of pin rollers arranged in sequence are installed inside the case. These pin rollers can effectively loosen and preliminarily disperse the sent shavings of the particle board when rotating, reducing material accumulation and creating good conditions for subsequent uniform material distribution. The scattering roller is located on one side of the pin roller and is also a group of scattering rollers arranged in sequence. When rotating, it further scatters the shavings processed by the pin roller through physical action, ensuring that the shavings are more evenly dispersed in a larger area, laying the foundation for uniformity of paving. The horizontal directional roller is located below the pin roller. The horizontal directional roller is arranged to accurately guide and arrange the shavings. Through its rotation and surface design, it guides the shavings to be evenly distributed in the horizontal direction, avoiding local accumulation or vacancy and improving the horizontal uniformity of paving. The longitudinal directional roller: arranged on one side of the horizontal directional roller and below the scattering roller, the longitudinal directional roller is responsible for guiding and arranging the shavings in the longitudinal direction, ensuring the uniform paving of the shavings in two dimensions and improving the flatness and structural strength of the final particle board. In summary, the device realizes efficient and accurate paving of the shavings of the particle board through the orderly cooperation of the pin roller, the scattering roller, the horizontal directional roller and the longitudinal directional roller, which is especially suitable for the production of particle board with high precision and uniformity, helps to improve the quality of finished products, reduces material waste and improves production efficiency. A part of the shavings forms a longitudinally arranged board blank under the rotation of the longitudinal directional roller, and the other part of the shavings forms a transversely arranged board blank under the action of the horizontal directional roller. At the same time, the speed of the horizontal directional roller can be adjusted and controlled to match the running speed of the lower belt; at the same time, the horizontal directional rollers are connected by synchronous belts and pulleys, and the angles between the rollers are adjusted to make the falling direction of the material different, so as to achieve the purpose of mutual filling of the material; under the precise coordination of the above three belt speeds, horizontal directional roller speeds and angles between the rollers, the material in a certain position of the board blank will not appear too high or too low. This control method is especially suitable for transverse paving of a small amount of shavings.

[0032] The device also comprises a plurality of screening rollers arranged in series, which constitute a continuous screening system. The arrangement of each screening roller ensures that the material can continuously and uniformly pass through the entire screening process. The screening rollers are driven by chains, and have a simple structure and are not prone to damage. Each screening roller is provided with a plurality of screening pieces arranged along the axial direction of the screening roller, forming a series of ordered screening intervals. The screening pieces on adjacent screening rollers are arranged in a staggered manner, and the screening piece and the corresponding screening piece on the adjacent same screening roller jointly form a screening interval, which is a key screening area. Each screening piece is provided with one or more screening notches. When there are multiple screening notches, they are arranged along the circumferential direction of the screening piece. Such a design is to accurately "capture" and remove the curved or non-size-requirement flake. The principle of removing the curved flake is that, in the working process, the raw flake passes through each screening interval with the rotation of the screening roller. Due to the presence of the screening notch, the curved flake that does not meet the size or shape requirements cannot pass through the notch smoothly when passing through the notch, and is effectively intercepted and removed from the screening process. While the straight and size-requirement flake can pass through smoothly and continue to the next process. At the same time, the arrangement of the screening notch enables the curved flake to be smoothly transferred from the screening notch under the rotation of the screening piece driven by the chain, so that the removed material can be smoothly discharged. In summary, the device realizes efficient screening of the flake through the fine design of the screening piece and the clever arrangement of the screening interval, removes the curved flake that affects the quality of the finished product, and provides raw materials with better quality for the subsequent flake board pressing process, thereby improving the quality and production efficiency of the final product. The screening roller is located above the pin roller and the scattering roller, and the screened material can directly fall onto the pin roller and the scattering roller, so that the finished flake board has better quality.

[0047] Referring to Figures 1-8 For the embodiment of the present application, a surface paving device capable of accurately and uniformly distributing materials in the transverse direction is provided, which comprises a machine box 3, a plurality of nail rollers 4 arranged in sequence and rotatingly arranged in the machine box 3, a plurality of scattering rollers 5 arranged in sequence and rotatingly arranged in the machine box 3 and located on one side of the nail rollers 4, a plurality of transverse directional rollers 6 arranged in sequence and located below the nail rollers 4, a plurality of longitudinal directional rollers 7 arranged in sequence and located on one side of the transverse directional rollers 6 and below the scattering rollers 5, a plurality of screening rollers 1 arranged in sequence and located above the nail rollers 4 and the scattering rollers 5, a plurality of screening pieces 2 arranged in sequence and located on the screening rollers 1, the screening pieces 2 being arranged in sequence along the axial direction of the screening rollers 1, a screening interval 201 being formed between two adjacent screening pieces 2, the screening piece 2 extending into the screening interval 201 on the adjacent screening roller 1, the screening piece 2 having one or more screening gaps 202, and the screening gaps 202 being arranged in a circumferential direction when there are a plurality of screening gaps 202.

[0048] In this embodiment, the case 3 is designed as the framework of the entire device, which provides a stable support platform to ensure the stable installation and efficient operation of all components, and facilitates the overall movement and maintenance of the device. The nail roller 4: a plurality of nail rollers 4 are arranged in sequence inside the case 3, which can effectively loosen and preliminarily disperse the sent flakeboard shavings when rotating, reducing material accumulation and creating good conditions for subsequent uniform material distribution. The scattering roller 5 is located on one side of the nail roller 4, which is also a group of scattering rollers 5 arranged in sequence. When rotating, it further scatters the flakeboard shavings processed by the nail roller 4 through physical action, ensuring that the flakeboard shavings are more evenly dispersed in a larger area, laying the foundation for uniformity of paving. The horizontal directional roller 6 is located below the nail roller 4, and the horizontal directional roller 6 is arranged to accurately guide and arrange the flakeboard shavings, which are guided to be evenly distributed in the horizontal direction through its rotation and surface design, avoiding local accumulation or vacancy and improving the horizontal uniformity of paving. The longitudinal directional roller 7: arranged on one side of the horizontal directional roller 6 and below the scattering roller 5, the longitudinal directional roller 7 is responsible for guiding and arranging the flakeboard shavings in the longitudinal direction, ensuring the uniform paving of the flakeboard shavings in two dimensions and improving the flatness and structural strength of the final flakeboard. In summary, through the orderly cooperation of the nail roller 4, the scattering roller 5, the horizontal directional roller 6 and the longitudinal directional roller 7, the device realizes efficient and accurate paving of flakeboard shavings, especially suitable for flakeboard production that requires high precision and uniformity, which helps to improve product quality, reduce material waste and improve production efficiency. A part of the shavings forms a longitudinally arranged board blank under the rotation of the longitudinal directional roller 7, and the other part of the shavings forms a horizontally arranged board blank under the action of the horizontal directional roller 6. At the same time, the speed of the horizontal directional roller 6 can be adjusted and controlled to match the running speed of the lower belt; at the same time, the horizontal directional rollers 6 are connected by synchronous belts and pulleys, and the angles between the rollers are adjusted to make the falling direction of the material different, so as to achieve the purpose of mutual filling of the material; under the precise coordination of the above three belt speeds, horizontal directional roller 6 speeds and the angles between the rollers, the material in a certain position of the board blank will not appear too high or too low. This control method is especially suitable for horizontal paving of a small amount of shavings.

[0049] The screening roller 1 is also designed, and the bending flake removing core component is a plurality of screening rollers 1 arranged in sequence, which constitute a continuous operation removing system. The arrangement of each screening roller 1 ensures that the material can continuously and uniformly pass through the entire removing process. The screening roller 1 is driven by a chain, which has a simple structure and is not easy to be damaged. A plurality of removing pieces 2 are arranged on each screening roller 1, which are arranged along the axial direction of the screening roller 1 to form a series of ordered removing intervals 201. The removing pieces 2 on adjacent screening rollers 1 are staggered, and the removing piece 2 and the corresponding removing piece 2 on the adjacent same screening roller 1 jointly form a removing interval 201, which is a key screening area. One or more removing gaps 202 are designed on each removing piece 2. When there are a plurality of removing gaps 202, they are arranged along the circumferential direction of the removing piece 2. Such design is to accurately "capture" and remove the bending or non-size-required flake. The principle of removing the bending flake is that, in the working process, the raw flake passes through each removing interval 201 with the rotation of the screening roller 1. Due to the existence of the removing gap 202, the bending flake that does not meet the size or shape requirements cannot pass through the gap smoothly when passing through, so as to be effectively intercepted and removed from the removing process. While the straight and size-suitable flake can pass through smoothly and continue to the next process. At the same time, the arrangement of the removing gap 202 enables the bending flake to be smoothly transferred by the removing gap 202 under the rotation of the removing piece 2 driven by the chain, so that the removed material can be smoothly discharged. In summary, the device realizes efficient screening of the flake through the fine design of the removing piece 2 and the clever arrangement of the removing interval 201, removes the bending flake that affects the quality of the finished product, provides raw materials with better quality for the subsequent flake board pressing process, and improves the quality and production efficiency of the final product. The screening roller 1 is located above the nail roller 4 and the scattering roller 5, and the screened material can directly fall above the nail roller 4 and the scattering roller 5, so that the quality of the finished flake board is better.

[0050] Further, the machine case 3 has a material inlet 301 located above the nail roller 4 and the scattering roller 5.

[0051] In this embodiment, a material inlet is designed. The feed port 301 is cleverly positioned at the top of the chassis 3, precisely above the spike rollers 4 and scatter rollers 5. This layout leverages gravity, allowing wood shavings to fall directly in from above. After initial processing by the spike rollers 4 and scatter rollers 5, they are evenly distributed, improving material distribution efficiency. This design simplifies the material introduction process and reduces the complex guiding steps before the material enters the processing unit, allowing the material to enter the working state more quickly, thereby improving overall production efficiency and material processing speed. Because the material enters freely from above, the coordination between the spike rollers 4 and scatter rollers 5 naturally promotes material dispersion during its descent, facilitating the subsequent precise control of the transverse and longitudinal orientation rollers 7 and further ensuring transverse uniformity of the material distribution. The upper position of the feed port 301 facilitates material addition by operators or automated loading systems, reducing operational difficulty, the time and labor costs of manual intervention, and making the material replenishment process more intuitive and controllable. The design of feed inlet 301 also facilitates equipment maintenance and cleaning. Its elevated position reduces the amount of dust and impurities from the working environment that directly enter the equipment, maintaining internal cleanliness and extending the equipment's service life. In summary, by placing feed inlet 301 above chassis 3, this design not only improves the efficiency and uniformity of material introduction but also enhances the equipment's ease of use and maintenance, laying the foundation for efficient, precise, and uniform horizontal distribution of materials.

[0052] Furthermore, a plurality of spike rollers 4 and a plurality of scattering rollers 5 are arranged obliquely along a straight line.

[0053] In this embodiment, the inclined arrangement of the spike roller 4 and scatter roller 5 ensures that as the material passes through these rollers, it is not only dispersed by the rotation but also experiences a natural downward trend due to the angle of inclination. This design utilizes gravity to assist the downward movement of the material, accelerating its passage while further breaking up the material during its downward movement, improving its uniformity. The inclined arrangement can be further enhanced, with the transverse directional roller 6 having a plurality of circumferentially arranged arcuate blades 601. A transverse trough 602 is formed between adjacent arcuate blades 601, with the length of the transverse trough 602 parallel to the axial direction of the transverse directional roller 6.

[0054] Furthermore, the transverse orientation roller 6 has a plurality of circumferentially arranged arc blades 601 , and a transverse trough 602 is formed between two adjacent arc blades 601 . The length direction of the transverse trough 602 is parallel to the axial direction of the transverse orientation roller 6 .

[0055] In this embodiment, a plurality of arc-shaped blades 601 are arranged circumferentially on the transverse directional roller 6. This design not only increases the surface area in contact with the material, but also effectively guides and disperses the material in the transverse direction through the special shape of the blades. Each blade, when rotating, can exert uniform force on the passing material, promoting uniform movement and distribution of the material in the transverse direction. The transverse material channel 602 formed between two adjacent arc-shaped blades 601 has its length direction parallel to the axial direction of the transverse directional roller 6. Such a design aims to provide a clear transverse movement channel for the material, ensuring that the material can be accurately guided along the channel direction when passing through, avoiding random distribution of the material during transverse movement, thereby improving the transverse uniformity of the material. By adjusting the rotational speed of the transverse directional roller 6 and the shape and spacing of the blades, the flow speed and distribution state of the material in the transverse material channel 602 can be further accurately controlled, which is crucial for achieving a highly uniform material distribution. Especially when dealing with materials like chipboard chips that require fine paving, it can significantly improve the quality and consistency of the paving layer. The design of the transverse material channel 602 helps to reduce the accumulation or blockage of the material during conveying, ensuring the continuity and stability of the material flow, and avoiding uneven distribution of the material caused by local accumulation. In summary, by arranging arc-shaped blades 601 circumferentially on the transverse directional roller 6 and forming a transverse material channel 602, the surface layer paving equipment not only enhances the accurate control and uniform distribution of the material in the transverse direction, but also improves the overall processing efficiency and product quality, which is one of the key designs for achieving high-quality surface layer paving.

[0056] Further, it further comprises a guide plate 12, which is inclinedly arranged below the nailing roller 4 and above the transverse directional roller 6.

[0057] In this embodiment, the guide plate 12 is designed in an inclined state, installed directly below the pin roller 4 and above the transverse orientation roller 6. This inclined layout aims to utilize the principle of physical guidance to more efficiently guide and control the material flow after the preliminary treatment by the pin roller 4, ensuring that the material has smoothly moved along the predetermined path before entering the transverse orientation roller 6. By adjusting the inclination angle of the guide plate 12, the falling path and speed of the material in the vertical direction can be precisely controlled, helping to reduce the rebound and uneven dispersion of the material during the falling process, so that the material maintains a more consistent and concentrated state when entering the next processing unit, the transverse orientation roller 6, thereby improving the uniformity of subsequent paving. The inclined design of the guide plate 12 can also effectively avoid the accumulation of material during the falling process or the blockage at the entrance of the processing unit, ensuring the smoothness of continuous operation, reducing the downtime for cleaning, and improving the overall production efficiency. The presence of the guide plate 12, combined with its inclination angle and position, can preliminarily orient and spread the material, providing a good starting point for the subsequent fine paving of the transverse orientation roller 6, ensuring the lateral uniformity and overall flatness of the final paving layer. In summary, the inclined setting of the guide plate 12 plays a key role in this surface paving equipment, not only optimizing the control of material flow, but also further improving the efficiency of material processing and the uniformity of material distribution, which is one of the key design elements for achieving high-quality surface paving.

[0058] Further, the lower end of the guide plate 12 is directed towards the transverse chute 602.

[0059] In this embodiment, the lower end of the guide plate 12 is directed towards the transverse chute 602. This design ensures that the material processed from the pin roller 4 follows a clear and controlled path towards the transverse orientation roller 6. This direct orientation improves the accuracy of the material flow, reducing unnecessary scattering or deviation, allowing the material to enter the transverse chute 602 more concentrated and orderly. By aligning the lower end of the guide plate 12 with the transverse chute 602, the material can be better distributed evenly along the chute during the sliding process, avoiding accumulation or gaps before entering the transverse orientation roller 6, further ensuring the uniformity of the transverse paving. This is crucial for improving the flatness and structural strength of the final product, flakeboard. The design also promotes smooth flow of material during the guiding process, reducing friction and resistance, allowing the material to maintain good dynamics during flow, which is beneficial for the efficient work of subsequent processing units, improving the overall production efficiency and throughput capacity of the equipment. The precise orientation design of the guide plate 12 simplifies the maintenance and adjustment of the equipment. When adjusting the material flow or processing efficiency, the operator only needs to simply adjust the angle or position of the guide plate 12, which can quickly adapt to different production requirements or material characteristics. In summary, the design of the lower end of the guide plate 12 towards the transverse chute 602 not only strengthens the directional conveying and uniform distribution of the material, but also improves the overall efficiency of the equipment and the flexibility of the operation, which is an important part of achieving high-quality and efficient surface paving.

[0060] Further, it also includes an auxiliary guide plate 8, the upper end of the auxiliary guide plate 8 is connected with the guide plate 12, and the other end leads to the transverse chute 602.

[0061] In this embodiment, the upper end of the auxiliary guide plate 8 is connected to the main guide plate 12, and the other end is aligned with the transverse chute 602, forming a continuous and more rigorous material guide channel. This double-layer guide design ensures that the transition of material from the spike roller 4 to the transverse orientation roller 6 is smoother and more orderly, reducing the deviation or scattering of material during transmission. The presence of the auxiliary guide plate 8 provides an additional guide and constraint for the material, especially when the material flow is large or requires more precise control, effectively avoiding the turbulence or accumulation of material in high-speed motion, maintaining the consistency and uniformity of material flow. Through the connection of the auxiliary guide plate 8 and the main guide plate 12, the stability of the entire guide structure is enhanced. This not only helps to reduce the wear of the equipment during long-time operation, but also can cope with various unexpected situations that may occur during production, such as sudden increase of material or change of material texture, ensuring the continuous operation ability and reliability of the equipment. The design of the auxiliary guide plate 8 makes the adjustment of the entire guide system more flexible. If it is necessary to adjust the material guide path or optimize the uniformity of material distribution, the position or angle of the auxiliary guide plate 8 can be adjusted quickly without significantly changing the main structure, thereby simplifying the daily maintenance and parameter adjustment work. In summary, the addition of the auxiliary guide plate 8 significantly improves the accuracy and control ability of the surface paving equipment in material guiding, is the key design supplement to realize efficient and high-quality transverse uniform material distribution, and further optimizes the stability and efficiency of the entire production process.

[0062] Further, it further comprises a support plate 9, one end of the support plate 9 is arranged at the lower end of the guide plate 12, and the other end is arranged at the lower end of the auxiliary guide plate 8.

[0063] In this embodiment, the design of the support plate 9 is to further stabilize the structure of the guide plate 12 and the auxiliary guide plate 8, ensuring the stability and durability of the material guiding system. One end of the support plate 9 is fixed to the lower end of the guide plate 12, and the other end is fixed to the lower end of the auxiliary guide plate 8, forming a stable triangular support structure. This not only enhances the rigidity of the guide plate 12 and the auxiliary guide plate 8, preventing deformation or displacement under long-term operation or material impact, but also ensures the stable working state of the guiding system during high-speed operation. The addition of the support plate 9 shares the weight of the material and the dynamic load during movement, reducing the stress concentration of the guide plate 12 and the auxiliary guide plate 8, thereby prolonging the service life of the entire guiding system and improving the durability and reliability of the equipment. The structural design of the support plate 9 is convenient for installation and adjustment. When the guiding system needs to be maintained or adjusted, the support plate 9 serves as a unified support platform, simplifying the operation process and making it easier and more accurate to adjust the position or angle of the guide plate 12 and the auxiliary guide plate 8. The presence of the support plate 9 can also guide and regularize the material flow path, ensuring that the material can transition more smoothly into the horizontal chute 602 after passing through the guide plate 12 and the auxiliary guide plate 8, further improving the uniformity and efficiency of material flow. In summary, the addition of the support plate 9 not only stabilizes the physical structure of the guiding system, but also indirectly optimizes the guiding effect and uniformity of the material by improving the overall stability and durability of the equipment, making it an important design supplement to improve the comprehensive performance of the surface paving equipment.

[0064] Further, the longitudinally oriented roller 7 has a longitudinally oriented sheet 701, which is circular.

[0065] In this embodiment, the longitudinal orientation pieces 701 on the longitudinal orientation roller 7 have unique advantages compared to traditional flat or non-circular designs. The circular design means that regardless of the angle at which the material contacts the orientation pieces, a relatively uniform pushing force can be obtained, which helps the material move more smoothly in the longitudinal direction, reduces the resistance difference caused by shape, and ensures uniformity during paving. When the longitudinal orientation pieces rotate, their edges transition smoothly, reducing the likelihood of material being stuck or clamped, helping to continuously push the material forward, avoiding the formation of accumulations and gaps, and ensuring the continuity and stability of the material flow. Since the longitudinal orientation pieces 701 can uniformly contact and guide the material during rotation, this helps to achieve more accurate longitudinal distribution during paving, especially when handling large or small materials, which can ensure the uniformity of the paving layer and improve the quality of the final product. The smooth surface of the longitudinal orientation pieces 701 reduces wear points, which helps to extend the service life of the equipment and reduce maintenance costs. At the same time, its design is easy to clean, reducing the possibility of affecting work efficiency and accuracy due to impurities accumulating during use. In summary, the longitudinal orientation roller 7 design with circular longitudinal orientation pieces 701, through its unique geometry and motion characteristics, not only optimizes the distribution of material in the longitudinal direction, but also improves the efficiency and accuracy of the entire surface paving process, and is one of the key design elements to achieve high-quality material distribution.

[0066] Further, the longitudinal orientation pieces 701 on adjacent two longitudinal orientation rollers 7 are staggered.

[0067] In this embodiment, by staggering the circular orientation pieces on adjacent longitudinal orientation rollers 7, it can be ensured that each piece of material will be alternately acted upon by two adjacent orientation pieces as it passes through, regardless of how the material is distributed, and a uniform push and guide can be obtained. This design reduces the omission or accumulation of material in the longitudinal direction, improving the continuity and uniformity of the material distribution. The staggered orientation pieces can more finely control the flow of material, effectively filling even small gaps, avoiding the occurrence of voids or uneven thickness in the paving layer, and maintaining high-precision material distribution on high-speed production lines. Due to the staggering, each point of the material will be constrained by at least two orientation pieces as it passes through, reducing the slippage of the material in the longitudinal direction and ensuring the stability and controllability of the material during transmission, improving the overall production stability and product quality. The staggered design improves the adaptability of the equipment to different sizes of material, enhancing the versatility and flexibility of the equipment. In summary, the longitudinal orientation pieces 701 on adjacent longitudinal orientation rollers 7 are staggered, which not only optimizes the longitudinal guidance and uniform distribution of the material, but also improves the processing efficiency and accuracy of the equipment, and is one of the key technical innovations to achieve high-quality surface paving.

[0068] Further, the reject roller 1 comprises a rotating roller 101, which is rotatably arranged on the machine box 3, and the outer wall of the rotating roller 101 is provided with a first guide groove 102 extending along the axial direction of the rotating roller 101. A sleeve roller 103 is sleeved on the outer wall of the rotating roller 101, and the inner wall of the sleeve roller 103 is provided with a guide portion 104 which is slidingly arranged in the first guide groove 102. The outer wall of the sleeve roller 103 is provided with the reject piece 2.

[0069] In the embodiment, the rotating roller 101 is designed to be mounted on the machine box 3 and can rotate freely. A plurality of rotating rollers 101 are driven by the same chain and are driven by a driving member. The outer wall of the rotating roller 101 is provided with a first guide groove 102 extending along the axial direction thereof. This design provides a precise sliding track for the sleeve roller 103 sleeved on the outer wall of the rotating roller 101, ensuring the stability and guidance of the sleeve roller 103 during rotation. The sleeve roller 103, as an outer sleeve structure of the rotating roller 101, is sleeved on the outer periphery of the rotating roller 101, and the inner wall thereof is provided with a guide portion 104 matched with the first guide groove 102 of the outer wall of the rotating roller 101. This design enables the sleeve roller 103 to smoothly slide along the first guide groove 102 of the rotating roller 101, ensuring the dynamic adjustment capability of the sleeve roller 103 and the precise control of the position of the reject piece 2 under different working conditions. The outer wall of the sleeve roller 103 is fixedly mounted with a plurality of reject pieces 2, which are arranged along the circumferential direction of the sleeve roller 103, forming the key contact surface for rejecting the curved shaving. Since the sleeve roller 103 can slide along the first guide groove 102 on the rotating roller 101, the depth or position of the gap through which the shaving passes between the reject piece 2 and the sleeve roller 103 can be changed by adjusting the position of the sleeve roller 103, thereby avoiding the curved shaving from falling into the lower part at the reject gap 202. In summary, the combination of the rotating roller 101 and the sleeve roller 103, especially the precise matching of the first guide groove 102 and the guide portion 104, not only realizes the flexible adjustment of the position of the reject piece 2, but also improves the accuracy and adaptability of the entire rejection process, providing an efficient and adjustable mechanical device for rejecting the curved shaving, which is a key technical innovation for improving the production quality of the shaving board.

[0070] Further, the reject piece 2 is provided with a second guide groove 203 extending along the axial direction of the reject piece 2, and further comprises a sliding piece 204 slidingly arranged in the second guide groove 203 and extending into the reject gap 202. The sliding piece 204 is provided with a hook portion, and an elastic member 205 is arranged at one end of the second guide groove 203 and at the other end of the sliding piece 204, providing a force for the sliding piece 204 to approach the bottom of the second guide groove 203.

[0071] In this embodiment, the pick-up piece 2 is designed with a second guide groove 203. The outer edge of each pick-up piece 2 not only has a pick-up notch 202, but also has a second guide groove 203 extending in the axial direction. This design not only provides a track for the installation and adjustment of the slide 204, but also makes the structure of the pick-up piece 2 more complex and functional. The slide 204 is designed to be slidably arranged in the second guide groove 203 of the pick-up piece 2, and one end thereof can extend into the inside of the pick-up notch 202. The presence of the slide 204 enables the device to control the removal process more accurately, especially through the hook on the slide 204, which can further improve the efficiency and accuracy of removing bent shavings. One end of the elastic member 205 is fixed to the bottom of the second guide groove 203, and the other end is connected to the slide 204. Through the tension of the elastic member 205, a pulling force is provided to the slide 204 in the direction close to the bottom of the second guide groove 203. This design ensures that when the slide 204 rotates during the rejection process, after the slide 204 moves away from the bottom of the second guide groove 203 under the action of centrifugal force, the slide 204 can automatically reset. Even when it is impacted or vibrated by the material, it can quickly return to the set position to maintain effective contact between the rejection piece 2 and the material, avoiding the problem of reduced rejection efficiency or incomplete rejection due to looseness. In summary, this innovative design, through the combination of the slide 204 and the elastic member 205, not only achieves dynamic adjustment of the function of the rejection piece 2, but also improves the automation level and adaptability of the rejection process, ensuring the rejection accuracy and stability in continuous operation, and is the key to improving the overall performance of the equipment.

[0072] Furthermore, the outer side wall of the sleeve roller 103 has a material blocking plate 105 , which is located in the material removal interval 201 and is coplanar with the material removal sheet 2 in the same material removal interval 201 .

[0073] In this embodiment, the material blocking plate 105 is designed, and each outer side wall of the sleeve roller 103 is installed with the material blocking plate 105, which is placed inside each material removing interval 201. Such a layout ensures that the material blocking plate 105 is coplanar with the material removing piece 2 in the material removing interval 201, forming a continuous and flat screening interface. The presence of the material blocking plate 105 not only expands the screening contact area of the shaving piece, but also effectively blocks the unqualified curved shavings from passing through by working with the material removing piece 2, ensuring that only flat and qualified shavings can pass smoothly, thereby improving the accuracy and efficiency of screening. The design of the material blocking plate 105 and the sleeve roller 103 makes the whole screening structure more compact, reduces the assembly difficulty of separate components, and also facilitates the overall installation and adjustment, enhancing the stability of the device. Reducing the probability of missed detection, through the design of the coplanar material blocking plate 105 and the material removing piece 2, effectively reducing the missed detection during the removing process, even in high-speed operation state, it can guarantee the continuity and integrity of the screening, avoid the bending shavings mixed into the qualified materials, so as to improve the quality of the final shaving board product. In summary, the addition of the material blocking plate 105 is another innovative design to improve the screening accuracy and efficiency, which together with the material removing piece 2 forms a more rigorous screening barrier, ensuring the efficiency and stability of the production process, and the high-quality performance of the finished shaving board.

[0074] Further, the material blocking plate 105 has a protrusion 106, and the end of the material removing piece 2 in the same material removing interval 201 is located in the protrusion 106.

[0075] In this embodiment, each baffle plate 105 is designed with a specific protrusion 106. This design not only adapts to the structure of the reject piece 2, but also realizes the butt joint of the small gap with the reject piece 2. By extending the end of the reject piece 2 in the same reject interval 201 to the side of the protrusion 106 of the baffle plate 105, the gap between the two is ensured to be small, forming a continuous screening surface. The close fit of the protrusion 106 with the end of the reject piece 2 enhances the overall structural stability of the baffle plate 105 and the reject piece 2, ensuring good positioning even at high speed or under high pressure, avoiding misalignment or falling caused by vibration or impact, and ensuring the continuity and accuracy of the screening process. Through such design, the baffle plate 105 and the reject piece 2 together constitute a more precise screening mechanism, which can more accurately identify and reject curved or unqualified shavings, reducing the phenomenon of false rejection or missed rejection, thereby improving the accuracy and efficiency of screening. Optimizing material flow: The design of the protrusion 106 also takes into account the fluid mechanics of the material passing through, helping to reduce the resistance of the material when passing through the reject interval 201, making the material flow more smoothly, avoiding the problem of 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, and is one of the key designs to achieve high-quality shaving board production.

[0076] Further, the outer wall of the sleeve roller 103 has a reciprocating groove 107, and a guide 108 is arranged on the machine box 3 and slides in the reciprocating groove 107.

[0077] In this embodiment, the outer wall of the sleeve roller 103 is designed with a reciprocating groove 107, and a guide 108 is designed, which further enhances the adjustment flexibility and precise control ability of the device. The reciprocating groove 107 on the outer wall of the sleeve roller 103 provides a precise track for the sliding of the guide 108. This design allows the sleeve roller 103 to be finely adjusted along its axial direction without affecting the overall rotation function, which provides the possibility for the position adjustment of the rejected flake 2. The guide 108 is installed on the machine box 3 and can slide along the reciprocating groove 107 on the outer wall of the sleeve roller 103. The sliding of the guide 108 not only limits the sliding range of the sleeve roller 103, but also can realize the fine adjustment of the distance between the rejected flake 2 and the blocking plate 105 through precise positioning control, thereby reducing the possibility of accidental jamming of the shaving flake. Through the position adjustment of the guide 108, the device can maintain the optimal working state during the process of rejecting the curved shaving flake, reduce the jamming of the shaving flake to reduce the false rejection or missed rejection, improve the accuracy and efficiency of screening, and thus guarantee the material quality in the subsequent shaving board manufacturing process. In summary, by adding the reciprocating groove 107 on the outer wall of the sleeve roller 103 and cooperating with the sliding design of the guide 108, the device greatly improves the adjustment flexibility and control accuracy on the basis of maintaining the original function of rejecting the curved shaving flake, which provides important technical support for the production of high-quality shaving board.

[0078] Further, it further comprises an isolation sleeve 11, the isolation sleeve 11 is arranged on one side of the sleeve roller 103, and the isolation sleeve 11 has an expansion part, and the expansion part is abutted with the machine box 3.

[0079] In this embodiment, a isolation sleeve 11 is designed and installed on one side of the sleeve roller 103. The design of the isolation sleeve 11 aims to provide an additional protective layer to prevent external impurities or foreign matter from entering the working area of the sleeve roller 103 and the rejected piece 2, while also reducing the pollution of dust, debris and other mechanical internals, thereby prolonging the service life of the equipment. The isolation sleeve 11 is designed with an expansion part that can be in abutting arrangement with the machine box 3. The presence of the expansion part allows the isolation sleeve 11 to adapt to the slight displacement of the sleeve roller 103 during work or the dimensional change caused by temperature changes, maintaining good sealing performance, while also facilitating the installation and maintenance of the equipment, ensuring that the isolation sleeve 11 always fits tightly and effectively isolates external interference. Improve work stability: through the use of the isolation sleeve 11, the influence of external factors on the process of removing curved shavings can be reduced, ensuring the stability and screening accuracy of the screening process. The flexibility of the expansion part allows the entire device to maintain good working condition even in the face of changing working conditions during long-term operation, reducing the failure rate and improving the overall work efficiency. The design of the isolation sleeve 11 simplifies the daily cleaning and maintenance of the equipment, as the isolation sleeve 11 can be easily removed for easy inspection and cleaning of internal components, while also protecting core components from damage and reducing maintenance costs. In summary, the isolation sleeve 11 and the expansion part are designed to ensure the internal cleanliness of the device for removing curved shavings, reduce wear and tear, and improve the stability and work efficiency of the equipment, which is an effective design to improve production efficiency and maintenance convenience.
