Description

Technical Field

[0001] The present invention relates to the technical field of wood transportation, and particularly to a wood transportation device and a transportation method. Background Art

[0002] As an important building and industrial basic material, wood is widely used in many fields such as furniture manufacturing, construction engineering, packaging and transportation. With the mechanization and large-scale development of the wood processing industry, higher requirements are put forward for the efficient transportation of wood between storage areas, processing lines and sorting areas. Traditional wood transportation mainly relies on mechanical equipment such as belt conveyors, roller lines, chain plate lines, lifting platforms, etc. for short-distance or long-distance transfer, which is applicable to different forms of wood such as logs, boards and square timbers, and is widely used in sawmills, board factories and laminated wood processing workshops.

[0003] In the actual implementation process, there are still some problems: 1. In the process of wood handling and transfer by traditional transportation devices, there is generally a problem that impurities on the wood surface such as branches, dander, sediment, etc. cannot be cleaned in time. If these impurities are not processed in the transportation link, they are very likely to enter subsequent processing links such as cutting, grinding or pressing, resulting in blockage of processing equipment, increased tool wear and even deterioration of product quality. In the prior art, manual pre-cleaning or centralized treatment of wood surface impurities in an independent impurity removal process is usually adopted. Although it can improve the cleanliness of raw materials to a certain extent, there are obvious disadvantages in terms of efficiency, continuity and labor cost. Especially in a large-volume, assembly-line operation environment, manual impurity removal has low efficiency, poor consistency, and cannot ensure the cleanliness and standardized treatment of wood in subsequent processing, seriously restricting the improvement of production efficiency and automation level.

[0004] 2. The traditional wood transportation devices are mostly designed with transportation as the single goal in terms of structure, lacking effective limit fixing and adaptation mechanisms, resulting in easy deviation, rolling or inclination of wood during movement, especially more obvious when dealing with irregular or slippery-surface wood. Some traditional equipment attempts to use single-point clamps or rigid fixing devices for restraint, but it is often difficult to adapt to woods of different specifications and sizes, and it is easy to cause indentation or damage to the wood surface during the clamping process, affecting the subsequent processing accuracy and aesthetics. Therefore, how to achieve efficient and non-destructive clamping and fixing during transportation, ensure the stable transmission of wood and cooperate with a multi-functional processing structure for collaborative operation has become a technical bottleneck that traditional equipment is difficult to overcome.

[0018] For a better explanation and understanding of the present invention, the following will describe the present invention in detail with reference to the accompanying drawings and through specific embodiments.

[0019] Please refer to Figures 1 to 8 As shown, a wood transportation device and a transportation method of the present invention include a transportation device body 2. A deburring mechanism 4 is provided on the top of the transportation device body 2. The deburring mechanism 4 includes side plates 415, pressing springs 416, scrapers 417, and deburring brushes 418. One end of the pressing spring 416 is fixedly connected to the inner side of the side plate 415, and the other end of the pressing spring 416 is fixedly connected to a base plate 421. The top of the inner side of the base plate 421 is fixedly connected to the inner side of the scraper 417, and the bottom of the inner side of the base plate 421 is fixedly connected to the inner side of the deburring brush 418.

[0020] Optionally, two guide rails 1 are slidably connected to the bottom end of the transportation device body 2. Rack bars 401 are fixedly connected to the outer sides of the two guide rails 1, and two gears 413 are respectively meshed with the outer sides of the two rack bars 401. In the actual implementation process, by setting the guide rails 1 and the matching rack bar-gear 413 meshing structure, the transportation device body 2 can move linearly and stably on the preset track, effectively preventing the occurrence of deviation or jamming during operation, improving the stability and transmission efficiency of the transportation device body 2, and adapting to the precise transportation of wood bodies 3 of different lengths.

[0021] Optionally, drive rods 411 are fixedly connected to the inner sides of the two gears 413. Two drive wheels 406 are respectively provided on both sides of the two drive rods 411. A drive belt 407 is sleeved between the two drive wheels 406, and the inner sides of two of the drive wheels 406 are respectively fixedly connected to one end of the two drive rods 411. In the actual implementation process, the drive rods 411, drive wheels 406, and drive belt 407 form a linkage system, which can efficiently transmit the power generated by the rotation of the gears 413 to the transmission end, forming a stable synchronous rotation structure. This structure can not only improve the power transmission efficiency but also have a certain flexible adjustment ability, making the device run more smoothly and with less impact. The setting of the drive belt 407 can also reduce the direct wear between components, extend the overall service life, and improve the automation and mechanical coordination during transportation.

[0022] Optionally, fixed plates 409 are fixedly connected to both side walls of the main body 2 of the transportation device. Electric telescopic rods 414 are provided at the tops of the two fixed plates 409, and clamping plates 404 are fixedly connected to the free ends of the two electric telescopic rods 414. During actual implementation, the electric telescopic rod 414 drives the clamping plate 404 to move, which can flexibly adjust the position and strength of clamping the wood body 3, adapting to the clamping requirements of wood bodies 3 of different sizes. This structure realizes the clamping and releasing process of the wood body 3 through automatic control, with convenient and efficient operation, greatly reducing the frequency of manual intervention, improving safety and positioning accuracy, and providing stable support for the subsequent rotation or cleaning treatment of the wood body 3.

[0023] Optionally, a base 410 is fixedly connected to the top end of the main body 2 of the transportation device. The wood body 3 is placed inside the base 410. The inner sides of the two clamping plates 404 are respectively attached to both ends of the wood body 3. Two protective support arms 403 are hinged to the outside of the base 410. During actual implementation, the base 410 serves as a placement platform for the wood body 3 to provide load-bearing support, cooperating with the clamping plates 404 to limit and fix both ends of the wood body 3, preventing the wood body 3 from rolling or slipping. The protective support arms 403 are hinged to the outside of the base 410, and the angle can be adjusted according to the shape of the wood body 3 to form a lateral constraint, enhancing the fixing stability, preventing the wood body 3 from tipping over during movement or rotation, and improving the safety and overall operation reliability during transportation.

[0024] Optionally, limiting rods 412 are rotatably connected to the outside of two of the transmission wheels 406, and one ends of the two limiting rods 412 are respectively fixedly connected to the bottom ends of the two fixed plates 409. During actual implementation, the setting of the limiting rods 412 helps to constrain the position of the transmission system during operation, preventing the transmission wheels 406 from shifting or vibrating during high-speed operation. The limiting structure also plays a protective role, avoiding damage to parts or detachment of the transmission belt 407 caused by movement interference, improving the reliability and durability of the entire device operation, and being particularly suitable for continuous operation scenarios.

[0025] Optionally, sleeve rings 405 are fixedly sleeved on the outer walls of the two electric telescopic rods 414. Stable plates 408 are fixedly connected to the bottom ends of the two sleeve rings 405. The inner sides of the other two transmission wheels 406 are respectively fixedly connected to the outer walls of the two electric telescopic rods 414. The bottom ends of the two stable plates 408 are respectively fixedly connected to the top ends of the two fixed plates 409. During actual implementation, by connecting the transmission wheels 406 and the outer walls of the electric telescopic rods 414 through the stable plates 408 and realizing external support and positioning through the sleeve rings 405, the mechanical stability of each component during the transmission process can be effectively enhanced. The stable plates 408 form a stable platform, avoiding the phenomenon of asymmetric power caused by the deflection of the telescopic rod, improving the rigidity and consistency of the overall device operation, and being beneficial to ensuring the synchronism and accuracy of the clamping structure during movement.

[0026] Optionally, two clamps 402 are fixedly connected to the top of the base 410, a roller 419 is rotatably connected to the top of the base 410, a guard plate 422 is hinged to the top of the base 410, an electric push rod 420 is fixedly connected to the middle of the top of the base 410, and the output end of the electric push rod 420 is fixedly connected to the bottom end of the guard plate 422. In the actual implementation process, the clamp 402 is used to initially limit the wood body 3, the roller 419 and the guard plate 422 cooperate to control the rotation and protection operation of the wood body 3, and the electric push rod 420 drives the guard plate 422 to rotate, so that the impurity removal mechanism 4 on the inner side of the guard plate 422 fits with the surface of the wood body 3 to complete the scraping and cleaning functions. This structural design can realize the integrated processing of transportation, positioning, rotation and impurity removal, significantly improve the automation degree and processing efficiency of the device, and meet the needs of continuous production line operations.

[0027] Optionally, a method for transporting wood comprises the following steps: S1: placing the wood body 3 on the base 410 of the transport device body 2, and adjusting the positions of the two clamps 402 to initially limit the wood body 3; S2: operating the protective support arm 403 to hinge it to the outside of the base 410, so as to assist in fixing the wood body 3 to prevent it from tipping over or shifting during transportation; S3: Start the transport device body 2 to make it slide along the guide rail 1. At the same time, the gear 413 meshes and rotates with the rack 401, driving the transmission rod 411, the transmission wheel 406 and the transmission belt 407 to realize the power transmission of the transport device body 2. S4: When the transmission wheel 406 rotates, it can drive the electric telescopic rod 414 to rotate, so that its output end drives the clamping plate 404 to clamp the wood body 3, and the rolling rod 419 can drive the wood body 3 to rotate in place for subsequent processing; S5: Activate the electric push rod 420 to drive the guard plate 422 to rotate, so that the pressure spring 416 pushes the scraper 417 to fit against the outer wall of the wood body 3, scraping off the branches and impurities attached to the surface of the wood body 3. At the same time, the impurity removal brush 418 synchronously cleans the surface of the wood body 3. During the actual implementation process, the fixture 402 and the protective support arm 403 are used to double-limit and assist in fixing the wood body 3, effectively preventing the rolling, deviation or tilting of the wood body 3 during transportation, improving safety and transportation stability. Secondly, through the linkage mechanism composed of the guide rail 1, the gear 413, the rack 401, the transmission rod 411, the transmission wheel 406 and the transmission belt 407, it is ensured that the transportation device body 2 can move smoothly on the horizontal plane and achieve efficient power transmission. At the same time, the transmission system links the electric telescopic rod 414 and the clamping plate 404 to clamp the wood body 3 during transportation. The structure of the roller 419 can drive the wood body 3 to rotate locally, facilitating the pretreatment operation during transportation. Finally, the electric push rod 420 drives the guard plate 422 to rotate. Under the action of the pressure spring 416 inside the guard plate 422, the scraper 417 and the impurity removal brush 418 mechanically scrape and flexibly brush the surface of the wood body 3, significantly improving the surface cleanliness of the wood body 3 and providing good preparation conditions for subsequent processing procedures. This device integrates multiple functions such as transportation, limiting, and cleaning, is easy to operate, has high efficiency, and is suitable for the primary processing of the wood body 3 or the automated processing scenario of the production line.

[0028] Optionally, in S5, the impurity removal brush 418 is arranged below the scraper 417 at a certain angle with the outer wall of the wood body 3. During the actual implementation process, its function is to further improve the thoroughness and efficiency of impurity removal on the surface of the wood body 3. Since the scraper 417 is mainly responsible for initially scraping off the larger impurities or branches attached to the outer wall of the wood body 3, and the impurity removal brush 418 is the subsequent cleaning element, its installation position and angle play an important role. Arranging the impurity removal brush 418 below the scraper 417 and fitting it against the surface of the wood body 3 at a certain angle can make the bristles fully contact the small impurities such as bark fragments and sawdust dust remaining on the wood body 3 after scraping, realizing deep cleaning. This angle design makes the impurity removal brush 418 form an oblique sweeping effect during the movement along with the substrate 421, avoiding scraping damage to the wood body 3 and effectively improving the cleaning coverage and removal efficiency. In addition, since the impurity removal brush 418 itself has a certain flexibility, combined with the rigid effect of the scraper 417, a rigid-flexible combined cleaning structure is formed, which helps to adapt to the surface structures of wood bodies 3 with different shapes or roughnesses.

[0029] Working principle: First, place the wood body 3 to be transported in the base 410 above the device. The two ends of the wood body 3 are respectively attached to the inner sides of the two clamps 402 to achieve preliminary limit positioning. Subsequently, the user can operate the protective support arm 403 hinged on the outside of the device to make it fit the outer wall of the wood body 3, so as to further achieve stable support for the wood body 3 to prevent tilting and deviation on the basis of the clamps 402. After the limit is completed, start the transport device body 2. The transport device body 2 is arranged on the guide rail 1 and can slide along the direction of the guide rail 1. The gear 413 at its bottom meshes with the rack 401 fixedly arranged on the outside of the guide rail 1. During the sliding of the body, the gear 413 is driven to rotate synchronously. The gear 413 transmits the rotational power to the transmission wheel 406 on one side through the connected transmission rod 411, and transmits the power to the other transmission wheel 406 through the transmission belt 407, forming a complete closed-loop power transmission system. The external connection structure of the transmission wheel 406 and the electric telescopic rod 414 drives the telescopic rod to rotate synchronously. The user can further start the electric telescopic rod 414 to make its output end push the connected clamping plate 404 to clamp the wood body 3. Cooperating with the roller 419 structure at the top of the base 410, the axial rotation of the wood body 3 can be realized in the clamped state, which is convenient for subsequent cleaning or processing operations. During the transportation process, the impurity removal mechanism 4 at the top of the transport device body 2 starts to work synchronously. This mechanism is composed of a pressure spring 416, a scraper 417 and an impurity removal brush 418. One end of the pressure spring 416 is fixed to the inner side of the side plate 415, and the other end is connected to the substrate 421, so that it has an elastic telescopic function. The scraper 417 is installed on the inner side of the top of the substrate 421, and the impurity removal brush 418 is arranged on the inner side of the bottom of the substrate 421. When the guard plate 422 rotates to a suitable angle under the drive of the electric push rod 420, the pressure spring 416 releases its elastic force to push the scraper 417 to run along the outer wall of the wood body 3, scraping off impurities such as branches and burrs attached to the surface. At the same time, the impurity removal brush 418 contacts the surface of the wood body 3 to further complete the detailed cleaning. The whole process realizes the multi-functional coordination of the transportation, clamping, rotation and cleaning of the wood body 3, improves the transportation efficiency and automation level, ensures that the surface of the wood body 3 is clean, the position is accurate and the state is stable before entering the next process, and is applicable to the pre-processing scenarios such as sawing and planing.
