Abstract
Description
Technical Field
[0001] This utility model relates to the field of wood processing, and more specifically, to a large wood shaving sorting device. Background Technology
[0002] In the production of FOSB / OSB particleboard, the distribution of curled and irregularly shaped wood chips in the sub-surface blank has long been a bottleneck restricting product quality improvement. Traditional processes rely on manual picking of large-sized wood chips, but in the high-speed production line environment, manual operation is inefficient and extremely labor-intensive. Continuous operation easily leads to operator fatigue, resulting in increased false inspection rates and safety hazards. According to industry statistics, the surface defect rate caused by such curled wood chips can reach 15%, directly causing quality problems such as substandard board flatness and decreased physical properties, becoming a key technical bottleneck for improving the pass rate of high-end board products.
[0003] Existing production equipment lacks automated rejection capabilities for irregularly shaped wood shavings, resulting in persistent and unresolved issues with the quality fluctuations of the subsurface blanks. Manual intervention not only limits the potential for increased automation in production lines but also leads to insufficient process stability due to human factors. As market demands for higher surface quality in particleboard increase, traditional processes are insufficient to meet the production requirements of high-quality particleboard. The industry urgently needs an automated solution that is compatible with existing equipment and enables precise separation of irregularly shaped wood shavings to bridge the gap between quality improvement and safe production.
[0004] With the rapid development of the wood processing industry, wood shavings, as a major byproduct of wood shaving and sanding processes, have become a focus of industry attention for efficient processing and reuse. Traditional wood shaving processing methods rely on manual sorting or simple mechanical screening, which suffers from low efficiency, poor precision, and high labor intensity. In particular, for large-sized wood shavings (such as flaky wood shavings produced in furniture manufacturing and board processing), traditional equipment struggles to achieve precise separation and collection, leading to resource waste and environmental pollution.
[0005] The existing technology still has the following drawbacks:
[0006] (1) When processing wood boards of different thicknesses, the height of wood shavings may vary. A fixed height may not be able to effectively cover all areas. Wood shavings near the device may be blown away excessively, while wood shavings in the edge areas may not be able to enter the collection box due to insufficient wind, resulting in incomplete cleaning.
[0007] (2) Wood shavings accumulate on the surface of the equipment or in the working area and cannot be removed in time, reducing production efficiency: Wood shavings accumulation will block the gaps in the equipment, affect the subsequent processing flow, and even cause the production line to stop for cleaning, reducing overall production efficiency.
[0008] Therefore, a large wood shavings sorting device is proposed. Utility Model Content
[0009] This large-scale particle sorting device significantly improves the production efficiency and product quality of FOSB / OSB particleboard by automatically removing curled and irregularly shaped particleboard from the subsurface blanks. Traditional manual particleboard picking is not only inefficient but also prone to operator fatigue due to prolonged high-intensity work, increasing the false detection rate and safety risks. This device, utilizing airflow dynamics principles, precisely separates irregularly shaped particleboard, completely eliminating surface defects caused by curled particleboard. This significantly reduces the product defect rate from 15%, and substantially improves the flatness and physical properties of the boards.
[0010] Furthermore, this ingeniously designed device is compatible with existing paving head equipment. Through functions such as fan blade speed control, optimized rigidity of the particleboard collection tray, and automatic lifting adjustment, it achieves precise adaptation to particleboard blanks of different specifications and sizes. This innovation not only solves the problem of quality fluctuations in the subsurface blanks and improves process stability, but also promotes the deepening and improvement of production line automation, meeting the market's growing demand for high-quality particleboard. It provides the particleboard industry with a quality upgrade solution that combines economy and safety, and has significant value for widespread application.
[0011] To achieve the above-mentioned objectives, this utility model provides the following technical solution:
[0012] The present invention is as follows: a large wood shaving sorting device, including a base, a lifting component fixedly installed on the upper part of the base, an automatic rejection function core component fixedly installed inside the lifting component, and a collection component fixedly installed on the lower part of the automatic rejection function core component, the collection component being located at the upper part of the base;
[0013] The lifting assembly includes lifting motors located on both sides of the base. A lifting shaft is fixedly installed at one end of the lifting motor. A limit block is fixedly installed on the upper part of the lifting shaft. A first support rod is installed through the middle of the limit block. A lock is sleeved on the outer side of the first support rod.
[0014] As a preferred technical solution of this utility model, the core component of the automatic rejection function includes a slot plate located at the lower part of the latch. A drive motor is fixedly installed at the lower right side of the slot plate. A rotating shaft is installed at the output end of the drive motor. A baffle is provided on the rotating shaft. A fan blade roller is fixedly connected to the outer side of the rotating shaft. A blade is provided on the outer side of the fan blade roller. The baffle and the rotating shaft are rotatably connected through a bearing seat. The fan blade roller is located inside the baffle.
[0015] As a preferred technical solution of this utility model, the collection component includes a collection box located at the upper part of the base. The upper left and right sides of the collection box are fixedly installed with brackets. The brackets and the collection box are fixedly connected by bolts. A positioning plate is installed through the bracket. The upper part of the positioning plate fits against the inner side of the slot plate. The positioning plate and the slot plate are fixedly connected by bolts. A second support rod is fixedly installed at one end of the bracket. Limiting blocks pass through both ends of the second support rod.
[0016] As a preferred technical solution of this utility model, the upper part of the collection box is provided with a detachable receiving tray, the detachable receiving tray and the collection box are movably connected by a silicone sealing strip, and expansion plates are slidably installed on both the left and right sides of the collection box, the expansion plates and the collection box are connected by a limiting groove on the back of the collection box.
[0017] As a preferred technical solution of this utility model, the blades are evenly distributed in 9 groups on the outer side of the fan blade roller, and the blades are locked to the fan blade roller by bolts.
[0018] As a preferred embodiment of this invention, the collection box is located at the lower part of the blade, and the bracket is located at the rear of the collection box.
[0019] As a preferred technical solution of this utility model, the second support rod is located at the rear of the first support rod, and the second support rod and the first support rod are fixedly connected to the limiting block through a limiting groove.
[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0021] 1. With the lifting assembly in place, when the height of the device needs to be adjusted, the lifting motor drives the internal lifting reducer to move up and down linearly through the lifting shaft. The limit block at the top of the lifting shaft restricts the range of extension and retraction of the lifting shaft and serves as the support point for the first support rod. The first support rod moves up and down under the drive of the lifting shaft, thereby driving the entire automatic rejection function core component to move up and down. The locking buckle fixes the connection between the first support rod and the automatic rejection function core component, ensuring that it automatically adapts to the thickness requirements of different product specifications during the lifting process.
[0022] 2. Through the set automatic rejection function core component, when it is necessary to remove irregular shavings, the drive motor is started. The drive motor drives the rotating shaft to rotate. At the same time, the rotation drives the fan roller and blades to rotate. The rotation generates airflow, which blows the curled irregular shavings towards the collection component, effectively removing irregular shavings from the production line. At the same time, the baffle on the rotating shaft guides the airflow in the correct direction, preventing shavings from splashing outside the equipment or returning to the worktable surface under the action of the airflow.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.
[0030] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0031] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0033] like Figures 1-4As shown, this embodiment proposes a large wood shaving sorting device, including a base 1, a lifting component 2 fixedly installed on the upper part of the base 1, an automatic rejection function core component 3 fixedly installed inside the lifting component 2, and a collection component 4 fixedly installed on the lower part of the automatic rejection function core component 3, with the collection component 4 located at the upper part of the base 1.
[0034] The lifting assembly 2 includes lifting motors 203 located on both sides of the base 1. A lifting shaft 204 is fixedly installed at one end of the lifting motor 203. A limit block 205 is fixedly installed on the upper part of the lifting shaft 204. A first support rod 206 is installed through the middle of the limit block 205. A latch 207 is sleeved on the outer side of the first support rod 206. When the height of the device needs to be adjusted, the lifting motor 203 drives the internal lifting reducer to perform vertical linear telescopic movement through the lifting shaft 204. The limit block 205 on the upper part of the lifting shaft 204 limits the telescopic range of the lifting shaft 204 and serves as the support point for the first support rod 206. The first support rod 206 moves up and down under the drive of the lifting shaft 204, thereby driving the entire automatic rejection function core assembly 3 to move up and down. The latch 207 fixes the connection between the first support rod 206 and the automatic rejection function core assembly 3, ensuring that it automatically adapts to the thickness requirements of different product specifications during the lifting process.
[0035] like Figures 1-3 As shown, in a preferred embodiment, based on the above method, the core component 3 of the automatic rejection function further includes a slot plate 301 located at the lower part of the latch 207. A drive motor 302 is fixedly installed at the lower right side of the slot plate 301. A rotating shaft 303 is installed at the output end of the drive motor 302. A baffle 304 is provided on the rotating shaft 303. A fan blade roller 305 is fixedly connected to the outer side of the rotating shaft 303. A blade 306 is provided on the outer side of the fan blade roller 305. The baffle 304 and the rotating shaft 303 are rotatably connected through a bearing seat. The fan blade roller 305 is located inside the baffle 304. When it is necessary to remove irregularly shaped wood shavings, the drive motor 302 is started. The drive motor 302 drives the rotating shaft 303 to rotate. At the same time, the rotating shaft drives the fan roller 305 and the blades 306 to rotate. The rotation generates airflow, which blows the wood shavings toward the collection component 4, effectively removing irregularly shaped wood shavings from the production line. Meanwhile, the baffle 304 on the rotating shaft 303 guides the airflow in the correct direction, preventing the wood shavings from splashing outside the equipment or returning to the workbench surface under the action of the airflow.
[0036] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, in a preferred embodiment, based on the above method, the collection component 4 further includes a collection box 401 located on the upper part of the base 1. Supports 402 are fixedly installed on both the upper left and right sides of the collection box 401. The supports 402 and the collection box 401 are fixedly connected by bolts. A positioning plate 403 is installed through the support 402, with the upper part of the positioning plate 403 fitting against the inner side of the slot plate 301. The positioning plate 403 and the slot plate 301 are fixedly connected by bolts. A second support rod 404 is fixedly installed at one end of the support 402, and both ends of the second support rod 404 pass through limiting blocks 205. The bolts fixing the collection box 401 and the support 402 ensure the stability of the support 402, preventing the collection box 401 from tilting or shaking, greatly improving work efficiency.
[0037] like Figure 1 , Figure 2 and Figure 5 As shown, in a preferred embodiment, based on the above method, the upper part of the collection box 401 is further provided with a detachable receiving tray 5. The detachable receiving tray 5 is movably connected to the collection box 401 by a silicone sealing strip. The detachable receiving tray 5 is used to filter out small impurities and debris in the wood shavings. The movable connection of the silicone sealing strip facilitates disassembly and cleaning.
[0038] like Figure 3 As shown, in a preferred embodiment, based on the above method, nine groups of blades 306 are evenly distributed on the outer side of the fan blade roller 305, and the blades 306 are locked to the fan blade roller 305 by bolts. The fan blade roller 305 rotates as the shaft 303 rotates, and the blades 306 locked to the fan blade roller 305 rotate accordingly. The bolts are tightened to prevent loosening, making it suitable for high-speed rotation conditions.
[0039] like Figure 3 and Figure 5 As shown, in a preferred embodiment, based on the above method, the collection box 401 is further located at the lower part of the blade 306, and the support 402 is located at the rear of the collection box 401. The collection box 401, located at the lower part of the blade 306, can accurately receive the wood shavings blown from the blade 306, thus improving collection efficiency.
[0040] like Figure 2 , Figure 4 and Figure 5As shown, in a preferred embodiment, based on the above method, the second support rod 404 is further located at the rear of the first support rod 206, and the second support rod 404 and the first support rod 206 are fixedly connected to the limiting block 205 through a limiting groove. The first support rod 206 moves up and down under the drive of the lifting motor 203 and the lifting shaft 204. Since the second support rod 404 is also connected to the limiting block 205 through a limiting groove, it moves up and down synchronously with the first support rod 206, ensuring that the collection box 401 can always remain stable and will not tilt or shake.
[0041] Specifically, when using this wood shaving sorting device: when the device height needs to be adjusted, the lifting motor 203 drives the internal lifting reducer to move vertically and linearly through the lifting shaft 204. The limit block 205 on the upper part of the lifting shaft 204 serves as the support point for the first support rod 206. The first support rod 206 moves up and down under the drive of the lifting shaft 204, thereby driving the entire automatic rejection function core component 3 to move up and down. The locking buckle 207 fixes the connection between the first support rod 206 and the automatic rejection function core component 3, ensuring the stability of the automatic rejection function core component 3 during the lifting process. When shaving, the wood to be shaving is hoisted and placed according to the site height. On the other side of the slot plate 301, wood is shaving. When shaving begins, the drive motor 302 is started. The drive motor 302 drives the rotating shaft 303 to rotate. At the same time, the rotating shaft drives the fan roller 305 and the blades 306 to rotate. The rotation generates airflow, which blows the shavings toward the collection component 4, effectively removing shavings from the workbench or production line. At the same time, the baffle 304 on the rotating shaft 303 guides the airflow in the correct direction, preventing shavings from splashing outside the equipment or returning to the workbench surface under the action of the airflow. The detachable receiving tray 5 is used to filter out small impurities and debris in the shavings. The upper layer stores large shavings, and the small debris falls from the detachable receiving tray 5 into the lower layer for separate storage.
[0042] All technical features in this embodiment can be freely combined according to actual needs.
[0043] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
