Description

Technical Field

[0001] This invention relates to the field of wood processing equipment technology, specifically to a material bending device for processing wooden structure furniture. Background Technology

[0002] Wooden furniture refers to furniture primarily made from wood. Its various components are assembled using mortise and tenon joints, nails, glue, or other connectors to form furniture products with specific functions and aesthetic appeal. With the continuous improvement of people's living standards, the demand for wooden furniture is increasing. Whether in homes or offices, wooden furniture is highly favored for its beauty, environmental friendliness, and good texture. In the manufacturing process of wooden furniture, the bending and processing of the wood is a crucial step, and its quality directly affects the quality and performance of the final furniture product.

[0003] Currently, common bending devices for processing wooden furniture typically include basic heating, bending, and fixing functions. For example, they may include heating devices to soften the wood. To fix the wood, various clamping structures are used, such as screw-driven clamps or fixing devices with elastic washers, to ensure the relative stability of the wood during bending. Then, a power device, such as a hydraulic cylinder, drives the bending components to perform the bending operation.

[0004] However, in the existing technology, the wood lacks guidance and effective limiting during the process of entering the bending mechanism from the conveying stage. As a result, the wood is easily affected by external factors during the movement, such as slight collisions, vibrations or uneven pushing force during the conveying process. This can cause the wood to deviate from the predetermined entry path, making it impossible for the wood to be accurately aligned with the bending mechanism, thus affecting the bending accuracy. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a material bending device for processing wooden furniture structures. This device solves the problem in existing technologies where the wood lacks guidance and effective limiting during the process of moving from the conveying stage into the bending mechanism. This results in the wood being easily affected by external factors during movement, causing it to malfunction and fail to accurately align with the bending mechanism, thus affecting the bending accuracy.

[0012] Preferably, the storage box has multiple air inlets on its outer side, and the multiple air inlets are distributed on one side of the storage box.

[0013] Preferably, the heating mechanism includes two conveying pipes, which are respectively arranged on both sides of the interior of the heating box.

[0017] This invention provides a material bending device for processing wooden furniture. It has the following beneficial effects:

[0018] 1. This invention uses a sliding roller to initially guide the wood, effectively reducing frictional resistance and allowing for smoother wood movement, thus improving processing efficiency. The combination of springs and contact plates provides horizontal restraint, preventing damage to the wood surface and ensuring accurate entry into the bending mechanism. This significantly improves the positioning accuracy of wood bending, enhancing the quality stability of furniture material bending, reducing material scrap due to positioning deviations, lowering production costs, and ensuring high-efficiency and high-quality furniture production. When the two contact plates move towards each other via a cylinder, they can adaptively adjust according to the wood's dimensions.

[0019] 2. This invention generates low-temperature water using a semiconductor cooling box. Compared to traditional natural cooling or large-scale refrigeration equipment, it consumes less energy and provides a more stable cooling effect, efficiently cooling the serpentine tubes. Combined with a duct fan, it accelerates cold air circulation, allowing the bent wood to cool and set quickly and evenly. This not only improves production efficiency and shortens the processing cycle but also better maintains the accuracy of the bent wood shape, reducing shape deviations caused by uneven cooling, and improving the processing quality and finished product qualification rate of wooden furniture.

[0020] 3. This invention effectively reduces energy waste and dependence on external energy by recovering waste heat and steam heat from the heating box and transferring it to water in the water tank. This reduces production costs and makes the device more economical and efficient. In the wood processing process, the recovered heat can be used to preheat the wood or maintain a stable temperature and humidity environment in the heating box, ensuring that the wood is heated and softened evenly, which helps to improve the overall quality and efficiency of furniture processing.

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1-10This invention provides a material bending device for processing wooden furniture, including a support base 1 and a heating box 6. The support base 1 serves as the basic structure of the entire device, providing a stable and reliable installation platform for numerous components such as the bending mechanism 2, fixing mechanism 4, guide and limiting mechanism 3, cooling mechanism 5, and heating box 6. The heating box 6 provides a relatively enclosed space environment for heating and softening the wood. The bending mechanism 2 is located on the top of the support base 1, bending the wood into the desired shape. Fixing mechanisms 4 are located on both sides of the outer side of the bending mechanism 2, and are positioned on the top of the support base 1. The fixing mechanisms 4 can clamp and fix the wood, firmly securing it in the appropriate position. Compared with no fixing or insecure fixing, this effectively prevents the wood from moving or shifting during the bending process, ensuring that the bending operation is carried out accurately according to the predetermined direction and angle, improving the bending quality, and reducing bending errors caused by loose wood. One of the fixing mechanisms 4 has a guide and limiting mechanism 3 on the side away from the bending mechanism 2. The guide and limiting mechanism 3 can adaptively adjust according to the size of the wood, accurately position the wood, and avoid damaging the wood surface, ensuring that the wood accurately enters the bending mechanism 2. The other fixing mechanism 4 has a cooling mechanism 5 on the side away from the bending mechanism 2. Both the guide and limiting mechanism 3 and the cooling mechanism 5 are located on the top of the support base 1, accelerating the circulation of cold air and allowing the bent wood to cool and set quickly and evenly. Compared with natural cooling or poor cooling methods, this method can better maintain the accuracy of the bent wood shape, shorten the processing cycle, and improve production efficiency. The heating box 6 has a heating mechanism 7 inside, which can make the wood heat evenly. The heating box 6 has a recovery mechanism 8 on the outside. The recovery mechanism 8 can absorb the residual heat and steam in the heating box 6 and transfer them to the water in the water tank 801. On the one hand, it can effectively reduce energy waste, reduce dependence on external energy, save production costs, and make the device more economical and efficient; on the other hand, the recovered heat can be used to preheat the wood or maintain a stable temperature and humidity environment inside the heating box 6, ensuring that the wood is heated and softened evenly. Multiple placement plates 9 are fixedly connected to the inner wall of the heating box 6. The placement plates 9 can reasonably place the wood in layers, making the wood more orderly placed in the heating box 6.

[0034] The guide limiting mechanism 3 includes a connecting seat 301, which is fixedly connected to the top of the support seat 1. As the core load-bearing component of the guide limiting mechanism 3, the connecting seat 301 is securely connected to the support seat 1, providing a solid and reliable installation foundation for the entire guide limiting mechanism 3. Cylinders 305 are installed on both sides of the top of the connecting seat 301, with their telescopic ends facing each other. The cylinders 305 enable the guide limiting mechanism 3 to have flexible adjustment capabilities. By controlling the telescopic movement of the cylinders 305, the distance between the two contact plates 304 can be precisely adjusted according to the size of timber of different widths, achieving adaptive clamping of the timber. A connecting block 306 is fixedly connected to the telescopic end of the cylinder 305, effectively transmitting the telescopic force of the cylinder 305 to the contact plate 304. Connecting plates 302 are fixedly connected to opposite sides of the two connecting blocks 306. Springs 303 are fixedly connected to opposite sides of the two connecting plates 302. Contact plates 304 are fixedly connected to the proximal ends of the two springs 303. The combination of springs 303 and contact plates 304 achieves flexible limiting of the wood. When the contact plate 304 contacts the wood, the spring 303 provides a certain buffering force, which can make the contact plate 304 fit tightly against the wood surface, ensuring effective limiting of the wood and preventing it from shifting in the horizontal direction, while avoiding excessive rigid pressure on the wood and causing damage to the wood surface. Multiple sliding rollers 3011 are rotatably connected to the inner side of the connecting seat 301. The wood can be smoothly pushed along the rolling direction of the sliding rollers 3011, reducing energy consumption during the wood pushing process and improving feeding speed and efficiency.

[0035] Please see Figure 1 , Figure 2 and Figure 4Both connecting blocks 306 have stabilizing components on their outer sides. These components stabilize the connecting blocks 306 during movement. The connecting blocks 306 need to accurately move the contact plate 304 according to the drive of the cylinder 305. The stabilizing components prevent unnecessary shaking, offset, or twisting of the connecting blocks 306, allowing the contact plate 304 to precisely limit the movement of the wood, thus ensuring accurate horizontal positioning and improving the positioning accuracy when the wood enters the bending mechanism 2. The stabilizing components include connecting blocks 307, which are fixedly connected to the outer side of the connecting blocks 306. As the connecting part between the stabilizing components and the connecting blocks 306, the connecting blocks 307 provide a stable and reliable connection, ensuring effective force transmission and laying the foundation for the smooth movement of the connecting blocks 306. A connecting rod 308 is rotatably connected to the inner side of the connecting blocks 307, allowing the direction of force to be flexibly transmitted and converted during the movement of the connecting blocks 306. It can adapt to the force conditions of the connecting block 306 at different positions and different stages of movement, and also play a certain role in constraining the movement trajectory of the connecting block 306. The end of the connecting rod 308 away from the connecting block 307 is rotatably connected to the slider 309. When the connecting block 306 moves, the connecting rod 308 drives the slider 309 to move synchronously. The movement state of the slider 309, in turn, provides feedback adjustment to the movement of the connecting block 306 through the connecting rod 308, ensuring the stability of the connecting block 306 from multiple angles. A positioning frame 3010 is fixedly connected to one side of the top of the connecting seat 301. The internal through hole of the slider 309 is slidably connected to the outside of the positioning frame 3010. The positioning frame 3010 provides a fixed sliding track for the slider 309, so that the slider 309 can only slide along the direction defined by the positioning frame 3010.

[0036] Please see Figure 1 , Figure 2 and Figure 4 The fixing mechanism 4 includes two fixing frames 401, which are fixedly connected to the top of the support base 1. The two fixing frames 401 and the support base 1 are fixedly connected, forming a stable and reliable frame structure. A bidirectional threaded rod 402 is rotatably connected to the inner side of each fixing frame 401. Rotation of the bidirectional threaded rod 402 effectively and conveniently controls the distance between the two clamping plates 404, achieving adaptive clamping for timber of different widths. A handle 403 is fixedly connected to one end of the bidirectional threaded rod 402, providing the operator with a convenient and intuitive means to control the rotation of the bidirectional threaded rod 402. Two clamping plates 404 are threadedly connected to the outer side of the bidirectional threaded rod 402, enabling relative or opposite movement when the threaded rod rotates. When the bidirectional threaded rod 402 rotates, the two clamping plates 404 smoothly move closer or further away along the threaded trajectory of the threaded rod, thus tightly clamping the timber.

[0037] Please see Figure 1 , Figure 2 and Figure 4 A roller 406 is rotatably connected between the two fixing frames 401. The roller 406 penetrates the interior of the clamping plate 404. The rotational characteristics of the roller 406 create rolling friction between the wood and the fixing frames 401 and the clamping plate 404. When the wood needs to move slightly during the fixing process or before and after bending, rolling friction greatly reduces the friction force compared to traditional sliding friction. This allows the wood to move more smoothly within the fixing mechanism 4, reducing scratches and damage to the wood surface caused by friction and protecting the appearance quality of the wood. Rubber plates 405 are provided on adjacent sides of the two clamping plates 404. The rubber plates 405 have a certain degree of elasticity and friction; their elasticity provides a certain cushioning when clamping the wood.

[0038] Please see Figure 1 , Figure 2 , Figure 6 and Figure 7The cooling mechanism 5 includes a connecting frame 501, which is fixedly connected to the top of the support base 1. The connecting frame 501 and the support base 1 are fixed together, providing a stable installation platform for the numerous components of the entire cooling mechanism 5. A semiconductor cooling box 502 is mounted on the top of the connecting frame 501. Compared to traditional large-scale refrigeration units, the semiconductor cooling box 502 is small in size, compact in structure, and occupies less space, making it easy to install in furniture processing equipment. Moreover, it has high cooling efficiency and can quickly generate low-temperature water to provide a cold source for subsequent cooling processes. At the same time, semiconductor refrigeration technology is relatively energy-efficient, reducing energy costs while meeting cooling requirements, which meets the requirements of green production and energy conservation. A serpentine tube 506 is fixedly connected to the water inlet of the semiconductor cooling box 502. The special shape design of the serpentine tube 506 greatly increases the surface area for heat exchange with the outside environment, helping to quickly reduce the ambient air temperature. A water pump 503 is installed on the top of the connecting frame 501. The outlet of the water pump 503 is connected to the serpentine tube 506, and the inlet of the water pump 503 is connected to the outlet of the semiconductor cooling box 502 through the water supply pipe 504. The water pump 503 plays a key role in power transmission. It can stably and continuously deliver the low-temperature water generated by the semiconductor cooling box 502 to the serpentine tube 506, forming a closed water circulation loop. Driven by the water pump 503, the circulation of low-temperature water in the entire cooling system is ensured, so that low-temperature water always flows through the serpentine tube 506, maintaining a stable low-temperature environment and continuously providing cooling capacity for subsequent heat exchange and wood cooling. This improves the utilization rate of refrigeration resources, ensures the continuity and stability of the cooling process, and thus better achieves rapid cooling and shaping of the bent wood. A storage box 507 is fixedly connected to the top of the connecting frame 501. The serpentine tube 506 is set inside the storage box 507. The storage box 507 provides a relatively closed space for the serpentine tube 506, so that the cold energy emitted by the serpentine tube 506 can be concentrated in the storage box 507, avoiding the cold energy from being lost to the surrounding environment too quickly, and improving the utilization efficiency of the cold energy. A duct fan 508 is installed on the top of the connecting frame 501. The air inlet of the duct fan 508 is connected to the storage box 507 through the connecting pipe 509. The air outlet of the duct fan 508 is connected to the connecting pipe 5011 through the air supply pipe 5010. Multiple air outlet pipes 5012 are fixedly connected to the bottom of the connecting pipe 5011. The duct fan 508 can generate strong airflow power, which blows the cooled air in the storage box 507 through the air duct system composed of the connecting pipe 509, the air supply pipe 5010, the connecting pipe 5011 and the multiple air outlet pipes 5012 quickly and evenly onto the bent wood. Compared with natural convection cooling, this air circulation method greatly accelerates the heat exchange speed between the cold air and the wood, so that all parts of the wood can come into contact with the low temperature air in time, achieving a rapid and uniform cooling effect, effectively improving the quality of wood cooling and shaping, and ensuring that the shape of the bent wood can be maintained.

[0039] Please see Figure 7 The storage box 507 has multiple air inlets 505 on its outer side, which are distributed on one side of the storage box 507. The presence of the air inlets 505 allows outside air to enter the storage box 507, replenishing fresh air for the heat exchange process inside the storage box 507. On the one hand, this ensures the circulation and renewal of air inside the storage box 507, avoiding a decrease in cooling effect due to poor air circulation. On the other hand, the newly entered air can fully exchange heat with the serpentine tube 506, further improving the utilization efficiency of cooling capacity and helping to continuously maintain the low temperature environment inside the storage box 507.

[0040] Please see Figures 8-10 The heating mechanism 7 includes two delivery pipes 701, which are respectively located on both sides of the interior of the heating chamber 6. The distribution of the two delivery pipes 701 on both sides of the interior of the heating chamber 6 allows the heat medium to evenly cover the entire space of the heating chamber 6 from both sides towards the center. The delivery pipes 701 are fixedly connected to the inside of the heating chamber 6 by clamps 702. The clamps 702 securely fix the delivery pipes 701 to the inside of the heating chamber 6, and can withstand the pressure and temperature changes of the heat medium during heating, maintaining the stability of the delivery pipes 701 and preventing displacement or loosening due to vibration, thermal expansion and contraction, etc. Multiple nozzles 703 are fixedly connected to adjacent sides of the two delivery pipes 701. The multiple nozzles 703 can spray the heat medium onto the wood surface in a dispersed form. Compared to the heat medium flowing directly from the pipe opening, the nozzles 703 make the heat medium distribution finer and more uniform, increasing the contact area between the heat medium and the wood, improving heat transfer efficiency, accelerating the heating speed of the wood, and shortening the heating time. Two conveying pipes 701 are fixedly connected to a connecting pipe 704 on the side away from each other. The connecting pipe 704 provides a channel for the conveying pipe 701 to connect with an external heat medium source, so as to facilitate the introduction of steam medium into the conveying pipe 701.

[0041] Please see Figures 9-10The heat recovery mechanism 8 includes a water tank 801, which is fixedly connected to the outside of the heating box 6. As a key component of the heat recovery mechanism 8, the water tank 801 is rationally positioned to collect the waste heat and steam emitted by the heating box 6, creating favorable conditions for heat recovery and reuse. A heat exchange tube 802 is installed inside the water tank 801. One end of the heat exchange tube 802 penetrates the inner wall of the heating box 6 and extends into the interior of the heating box 6, while the other end penetrates the top of the water tank 801 and extends to the outside of the water tank 801. The heat exchange tube 802 forms a bridge for heat transfer between the heating box 6 and the water tank 801. One end of the heat exchanger tube 802 is inside the heating chamber 6, where it can fully absorb residual heat and steam heat. The other end extends to the outside of the water tank 801, where it can transfer the absorbed heat to the water inside the water tank 801. This allows heat to be efficiently transferred from the high-temperature heating chamber 6 to the water tank 801, achieving heat recovery and transfer. Compared to direct natural heat dissipation, this greatly improves the heat recovery and utilization rate and also raises the temperature of the water in the water tank 801 for subsequent preheating of the heating chamber 6. A valve 803 is installed on the outside of the heat exchanger tube 802. Operators can flexibly control the flow rate or on / off state of the fluid inside the heat exchanger tube 802 by opening or closing the valve 803 according to actual production conditions, such as the temperature inside the heating chamber 6, the water temperature requirements of the water tank 801, and the overall operating status of the device.

[0042] Please see Figures 9-10 A water inlet pipe 804 is fixedly connected to the outside of the water tank 801. The presence of the water inlet pipe 804 facilitates the replenishment of water into the water tank 801. During the heat recovery process, the water in the water tank 801 may be consumed or evaporated due to heat absorption. The water inlet pipe 804 ensures timely replenishment of water into the water tank 801, maintaining sufficient water volume in the water tank 801 for continuous heat absorption and storage. A water outlet pipe 805 is fixedly connected to the bottom of the water tank 801. The water outlet pipe 805 provides a channel for accessing the heated hot water in the water tank 801. The hot water can be led out for preheating inside the heating box 6 or for other production processes that require hot water, realizing the effective utilization of hot water and further expanding the application scope of heat recovery. An observation window 806 is provided on the side of the water tank 801 away from the heating box 6, allowing operators to directly observe the water level in the water tank 801.

[0043] Please see Figures 1-3The bending mechanism 2 includes a mounting frame 201, which is fixedly connected to the top of the support base 1. The mounting frame 201 and the support base 1 are fixed together, forming a stable foundation frame for the entire bending mechanism 2. A hydraulic cylinder 202 is mounted on the top of the mounting frame 201. During the bending process, the hydraulic cylinder 202 provides sufficient and stable thrust as needed, driving the bending head 203 to apply pressure to the wood, thus achieving the bending operation. The extension end of the hydraulic cylinder 202 is fixedly connected to the bending head 203. As the component that directly contacts the wood and applies bending force, the bending head 203 effectively transmits the thrust generated by the hydraulic cylinder 202 to the wood. A fixing plate 204 is provided directly below the bending head 203. The fixing plate 204 is fixedly connected to the top of the support base 1. The fixing plate 204 is fixed to the top of the support base 1 and located directly below the bending head 203. It plays a crucial auxiliary role in the bending operation of wood. It provides a stable support surface for the wood. In conjunction with the bending head 203, it ensures that the wood has a clear bending reference position during the bending process.

[0044] Working principle: First, an external steam source enters the delivery pipe 701 through the connecting pipe 704, and then is sprayed out from multiple nozzles 703 to heat the wood placed on the placement plate 9 inside the heating box 6. During the heating process, the steam or hot medium softens the wood, making it easier to bend later.

[0045] By opening valve 803, the waste heat and steam in heating box 6 are absorbed by heat exchange tube 802. The heat is transferred to the water in water tank 801 through heat exchange tube 802, so that the water in water tank 801 has a certain temperature, which can provide heat to the interior of heating box 6. The hot water in water tank 801 can be taken out through water outlet pipe 805, realizing the recovery and utilization of waste heat, thereby improving energy utilization efficiency and reducing energy consumption.

[0046] When the wood is pushed to the guide limiting mechanism 3, multiple sliding rollers 3011 on the inner side of the connecting seat 301 first contact the wood. The sliding rollers 3011 can rotate freely under the push of the wood, providing initial guidance and ensuring the wood moves in the predetermined direction. Next, the cylinder 305 is activated, and its telescopic end extends, pushing the connecting block 306 towards the wood. As the connecting block 306 moves, it drives the spring 303 and contact plate 304 towards the wood via the connecting plate 302. After the contact plate 304 contacts the wood, the spring 303 is gradually compressed as the cylinder 305 continues to push the connecting block 306. The compression of the spring 303 provides a certain buffering force, ensuring that the contact plate 304 fits tightly against the wood surface while avoiding excessive rigid pressure that could damage the wood surface. Through the cooperation of the spring 303 and the contact plate 304, the wood is limited from both sides, preventing horizontal displacement and ensuring that the wood accurately enters the bending mechanism 2 during subsequent bending operations. During the movement of the connecting block 306, the connecting block 307 on its outer side will drive the connecting rod 308 to rotate, so that the slider 309 slides outside the positioning frame 3010, so that the connecting block 306 is constrained by the stabilizing component when it moves, and can only move smoothly along the direction defined by the positioning frame 3010.

[0047] The front and rear ends of the timber are then moved between the corresponding two fixed frames 401. By rotating the handle 403, the double-threaded rod 402 is rotated. The two clamping plates 404 on the double-threaded rod 402 move relative to or away from each other under the action of the threads, and work with the rubber plate 405 to clamp and fix the timber. At the same time, the roller 406 can play an auxiliary rolling support role during the pushing or bending of the timber, reducing the frictional resistance between the timber and the fixed frame 401, and facilitating the smooth movement and bending operation of the timber.

[0048] When the wood is fixed, the hydraulic cylinder 202 is activated, and the extension end of the hydraulic cylinder 202 pushes the bending head 203 downward, pressing the wood onto the fixed plate 204 to perform a bending operation. The bending head 203 bends the wood into the required shape according to the preset shape and angle.

[0049] Once the wood is bent, the fixing mechanism 4 releases the wood and moves it into the cooling mechanism 5. The semiconductor cooling box 502 generates low-temperature water, and the water pump 503 transports the low-temperature water from the semiconductor cooling box 502 to the serpentine tube 506 through the water pipe 504. The serpentine tube 506 is located inside the storage box 507. Outside air enters the storage box 507 through the air inlet 505 on the outside of the storage box 507. After heat exchange with the serpentine tube 506, the temperature decreases, and the duct fan 508 starts, blowing the cold air inside the storage box 507 out through the connecting pipe 509, the air supply pipe 5010, and the connecting pipe 5011 from multiple air outlet pipes 5012 to cool the bent wood, allowing it to cool and set quickly, maintaining its bent shape.

[0050] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
