Description

Technical Field

[0001] The present invention belongs to the technical field of wood product processing, and relates to an arc bending and shaping device for wood product processing. Background Art

[0002] In the field of wood product processing, the process of bending wood into an arc to meet the specific product design requirements is very common, such as the production of arc-shaped chair backs, armrests and other components in furniture manufacturing. With the continuous improvement of people's requirements for the aesthetics and functionality of wood products, higher standards have also been put forward for the arc bending and shaping process and the performance of the corresponding devices.

[0003] Existing devices mostly operate in a single batch, and the connection between each process is not smooth enough. The transfer time of wood between different processes is long, resulting in low overall production efficiency and difficulty in meeting the large-scale production requirements. At the same time, the energy consumption in links such as heating and drying is relatively large, and there is a lack of an effective energy recovery and utilization mechanism, resulting in energy waste and increased production costs.

[0004] After retrieval, for example, a bamboo and wood product arc bending and shaping device is disclosed in Chinese patent literature

Application No.: 202323279912.0; Publication No.: CN221912430U

[0005] Although the bamboo and wood product arc bending and shaping device disclosed in this patent can bend bamboo and wood products at different arc bending angles and cool and dry the bamboos and woods below, this bamboo and wood product arc bending and shaping device operates in a single batch, the process connection is not smooth, the production efficiency is low, and the energy consumption is high.

[0006] Therefore, we propose an arc bending and shaping device for wood product processing, in which each mechanism operates in coordination, and each mechanism conducts continuous processing on the wood products, including conveying and preheating, grasping and transferring, secondary preheating, water bath bending, drying and discharging. It has high efficiency, realizes continuous production, and at the same time has low energy consumption and reduces production costs. Summary of the Invention

[0007] The object of the present invention is to address the above problems existing in the prior art and propose an arc bending and shaping device for wood product processing. The technical problem to be solved by this invention is: how to perform continuous processing on wood products, including conveying and preheating, grasping and transferring, secondary preheating, water bath bending, and drying and discharging. Each mechanism operates in coordination with high efficiency to achieve continuous production, while consuming less energy and reducing production costs.

[0008] The object of the present invention can be achieved by the following technical solutions:

[0009] An arc bending and shaping device for wood product processing includes a conveying mechanism, a water bath bending and shaping mechanism, a rotating mechanism, and two preheating and drying mechanisms. Four circumferentially evenly distributed indexing mechanisms are provided below the rotating mechanism, and six circumferentially evenly distributed clamping mechanisms are provided on each indexing mechanism. The conveying mechanism, the water bath bending and shaping mechanism, and the two preheating and drying mechanisms are circumferentially evenly distributed below the rotating mechanism. The two preheating and drying mechanisms are symmetrically arranged on both sides of the rotating mechanism. The positions of the conveying mechanism and the water bath bending and shaping mechanism are symmetrical with respect to both sides of the rotating mechanism. The conveying mechanism, the water bath bending and shaping mechanism, and the two preheating and drying mechanisms are all located below the corresponding indexing mechanisms.

[0010] The water bath bending and shaping mechanism is connected to a filter, the filter is connected to an exhaust fan, and the air outlet of the exhaust fan is connected to the conveying mechanism and the two preheating and drying mechanisms through pipelines respectively.

[0011] The working principle of the present invention is: according to the size of the wood product, select the specification of the clamping mechanism and adjust the size of the water bath bending and shaping mechanism;

[0012] Place the wood products to be processed on the conveying mechanism in sequence. The conveying mechanism performs a primary preheating treatment on the wood products to be processed and conveys the wood products to be processed to a position corresponding to the indexing mechanism and directly below one of the clamping mechanisms. At this time, the wood products to be processed are placed vertically. The rotating mechanism cooperates with one of the clamping mechanisms to clamp the wood products to be processed downward. After the clamping mechanism clamps the wood products, it rises to its original position. The next clamping mechanism is rotated through the indexing mechanism to repeat the above clamping process until all the clamping mechanisms on the indexing mechanism are fully loaded;

[0013] The rotating mechanism rotates clockwise by [X] degrees, driving the indexing mechanism loaded with workpieces to rotate above one of the preheating and drying mechanisms. The rotating mechanism cooperates with the clamping mechanism to send the wood products into the preheating and drying mechanism, where the wood products are subjected to secondary preheating treatment to facilitate subsequent bending. After the preheating treatment of the wood products, the rotating mechanism rotates clockwise by [X] degrees again, rotating the indexing mechanism loaded with workpieces above the water bath bending and shaping mechanism. The rotating mechanism cooperates with the clamping mechanism to send the wood products into the water bath bending and shaping mechanism. In the water bath environment, the wood is bent into the required arc shape. At the same time, the clamping mechanism of the indexing mechanism located above the conveying mechanism repeats the above clamping process to start clamping the wood products on the conveying mechanism until the clamping mechanism is fully loaded. After the wood products in the water bath bending and shaping mechanism are bent, the rotating mechanism rotates counterclockwise by [X] degrees, turning the fully loaded and bent wood products on the indexing mechanism back to the preheating and drying mechanism, where the wood is dried. Finally, the dried and formed wood products are taken out. Another indexing mechanism loaded with unbent wood products rotates into another preheating and drying mechanism to repeat the above secondary preheating treatment. After the preheating is completed, the rotating mechanism rotates counterclockwise by [X] degrees again, rotating the indexing mechanism above the water bath bending and shaping mechanism to repeat the above process;

[0014] There is a large amount of steam inside the water bath bending and shaping mechanism. The moisture in the steam is removed through a filter to obtain hot air, which is extracted by an exhaust fan and sent to the conveying mechanism and the two preheating and drying mechanisms through the air outlet of the exhaust fan for the above-mentioned primary preheating, secondary preheating and drying treatment of the wood products.

[0015] The rotating mechanism includes a rotating base, a rotating column fixed above the rotating base, a rotating table I rotatably provided above the rotating column, a rotating motor fixed above the rotating column, a rotating frame fixed on the rotating table I, and the driving shaft of the rotating motor is in transmission connection with the rotating table I. Four evenly circumferentially distributed lifting hydraulic cylinders are fixed on the rotating frame.

[0016] With the above structure, the driving shaft of the rotating motor drives the rotating table I to rotate intermittently clockwise or counterclockwise by [X] degrees, and then drives the rotating frame to rotate through the rotating table I. The indexing mechanism on the rotating frame successively reaches the conveying mechanism, the preheating and drying mechanism and the water bath bending and shaping mechanism. At the same time, the lifting hydraulic cylinders drive the indexing mechanism to lift and lower according to different height requirements to adjust the height of the indexing mechanism.

[0017] The indexing mechanism includes a cam divider, which is fixed below the corresponding lifting hydraulic cylinder. A rotating table II is fixed on the driving shaft of the cam divider. A indexing plate is fixed below the rotating table II. The clamping mechanism includes an electric push rod and an electric claw. The electric push rod is fixed on the indexing plate. The telescopic end of the electric push rod passes through the indexing plate, and the electric claw is fixed on the telescopic end of the electric push rod. A detachable claw stopper is provided inside the claw rod of the electric claw.

[0018] With the above structure, according to the size and shape of the wood products, adjust the size and shape of the replacement jaw stoppers; the driving shaft of the cam divider drives the rotary table two and the indexing plate below to rotate intermittently. First, rotate clockwise by degrees in sequence for one week, and then rotate counterclockwise by degrees in the next week for one week. The purpose is to facilitate the layout of wires. The indexing plate drives the six circumferentially evenly distributed clamping mechanisms to rotate, so that the electric jaws correspond to the wood products on the conveying mechanism up and down. The lifting hydraulic cylinder drives the indexing mechanism to move downward, and the electric push rod drives the electric jaws to move downward to make the lifting distance larger. After the electric jaws clamp the wood products, the electric push rod drives the electric jaws to rise to the original position, and the lifting hydraulic cylinder drives the indexing mechanism back to the original position until all the electric jaws are fully loaded;

[0019] The rotating mechanism drives the fully loaded indexing mechanism to move to the preheating and drying mechanism and the water bath bending and shaping mechanism. The lifting hydraulic cylinder and all the electric push rods cooperate to place the wood products into the preheating and drying mechanism and the water bath bending and shaping mechanism for preheating, drying and bending treatment.

[0020] The conveying mechanism includes a sliding roller conveyor. A wind guiding box is fixed at the upper end of the sliding roller conveyor. A hot air connector one is fixed on the outside of the sliding roller conveyor. The hot air connector one is connected to the wind guiding box. A pipeline is connected between the hot air connector one and the air outlet of the exhaust fan. Two guiding plates are arranged at the upper end of the sliding roller conveying frame. The two guiding plates form a channel with a smaller front and a larger rear. The guiding plates are located in front of the wind guiding box. A discharging chute is arranged at the front ends of the two guiding plates.

[0021] With the above structure, place the wood products to be processed on the sliding roller conveyor in sequence. The hot air enters the wind guiding box through the hot air connector one. The wind guiding box conducts a primary preheating treatment on the wood products to be processed. The wood products to be processed are conveyed to the discharging chute through the guiding plates. The wood products to be processed correspond to the position of the indexing mechanism and are directly below one of the clamping mechanisms. At this time, the wood products to be processed are placed vertically.

[0022] The preheating and drying mechanism includes a preheating and drying box. Two symmetric baffle rails are fixed on the outside of the preheating and drying box. An unloading baffle slides on the two baffle rails. An unloading port is opened on the outside of the preheating and drying box. The unloading port is located between the two baffle rails. A hot air connector two is arranged on the outside of the preheating and drying box and is connected to it. A pipeline is connected between the hot air connector two and the air outlet of the exhaust fan. An inclined sliding roller frame is arranged inside the preheating and drying box. The lowermost end of the sliding roller frame is aligned with the lower end face of the unloading port. The hot air connector two is located below the sliding roller frame. An avoidance port one corresponding to the electric jaws is opened at the top of the preheating and drying box.

[0023] With the above structure, the wooden products enter the preheating drying box through the avoidance port 1 at the top, and the hot air enters the preheating drying box through the hot air joint to perform secondary preheating treatment or drying treatment on the wooden products. The electric clamp rises to drive the wooden products that have undergone secondary preheating treatment to leave the preheating drying box through the avoidance port 1, and the dried wooden products are directly placed in the preheating drying box. Under the action of gravity, the wooden products slide down along the inclined sliding roller frame to reach the discharge port, and then the dried wooden products are taken out manually.

[0024] The water bath bending and shaping mechanism includes a heating base, a bending and shaping water tank is fixed above the heating base, a water injection joint, a steam outlet pipe joint and a water drain joint connected to the bending and shaping water tank are arranged on the outside of the bending and shaping water tank, the steam outlet pipe joint and the water injection joint are at the same height, the water drain joint is located at the outside and below of the bending and shaping water tank, a second avoidance port corresponding to the electric clamp is arranged on the top of the bending and shaping water tank, six circumferentially evenly distributed bending and shaping components are arranged inside the bending and shaping water tank, and the steam outlet pipe joint is located above the bending and shaping components; the filter is connected to the steam outlet pipe joint by a pipe, and the filter is connected to the exhaust fan.

[0025] With the above structure, water is first injected into the bending and shaping water tank through the water injection joint until the water covers the bending and shaping component, and then the heating base heats the water in the water tank to make the water reach the set temperature to form a hot water bath environment. The electric clamp clamps the wooden product and enters the water tank through the avoidance port 2 at the top of the bending and shaping water tank. The wooden product is passed through the bending and shaping component at the corresponding position. In the hot water bath environment, the wood softens due to the action of water, making it easier to bend into the desired arc shape under the action of the bending and shaping component. After the processing is completed, the bent and shaped wooden product leaves the bending and shaping water tank through the avoidance port 2.

[0026] During the heating and bending process, there is a large amount of steam inside the water bath bending and shaping mechanism. The steam is discharged through the steam outlet pipe joint and reaches the filter. The filter removes moisture from the steam to obtain hot air, which is then extracted through the exhaust fan.

[0027] The bending and shaping component includes a shaping base plate, which is fixed to the bottom of the bending and shaping water tank, a cylinder and a transmission rod are fixed on the shaping base plate, a rack is provided above the telescopic end of the cylinder, a gear is rotatably provided on the transmission rod, the gear and the rack are meshed, a fixed roller is rotatably provided on the end of the transmission rod, a telescopic sleeve rod is fixed to the side of the gear, a movable screw 2 is screwed on the telescopic sleeve rod, a rotating roller is rotatably provided on the telescopic sleeve rod, a positioning frame is slidably provided on the shaping base plate, a movable screw 1 is screwed on the shaping base plate, and the end of the movable screw 1 abuts against the positioning frame.

[0028] With the above structure, according to the size and shape of the wooden product, the position of the telescopic sleeve rod is adjusted, and the position of the telescopic sleeve rod is locked and fixed by the movable screw two. Furthermore, the position of the rotating roller is determined. According to the size and shape of the wooden product, the position of the positioning frame is slidably adjusted, and then the position of the positioning frame is locked and fixed by the movable screw one;

[0029] The electric gripper clamps the wooden product and moves it downward, enabling the wooden product to pass through between the rotating roller and the fixed roller at the corresponding position. The wooden product is placed between the fixed roller and the rotating roller, and the positioning frame plays a role in positioning the wooden product. At this time, the cylinder two pushes the rack to move, the rack drives the gear to rotate, the gear slowly rotates on the transmission rod, the gear drives the telescopic sleeve rod to rotate, thereby driving the rotating roller to rotate. The rotating roller slowly rotates with the fixed roller as the center of the circle, and further bends the wooden product into the required arc shape.

[0030] Compared with the prior art, the arc bending and shaping device for processing wooden products has the following advantages:

[0031] The conveying mechanism continuously conveys the wooden products and places them vertically;

[0032] The rotating mechanism, indexing mechanism, and clamping mechanism cooperate to quickly grasp and transfer the wooden products. At the same time, in cooperation with the water bath bending and shaping mechanism, the wooden products are bent and formed, and in cooperation with the preheating and drying mechanism, the wooden products are preheated and dried;

[0033] The water bath bending and shaping mechanism, conveying mechanism, and preheating and drying mechanism cooperate. The steam of the water bath bending and shaping mechanism is treated and then conveyed to the conveying mechanism and the preheating and drying mechanism to preheat and dry the wooden products, realizing resource recycling, reducing energy consumption, improving energy utilization rate, and meeting environmental protection requirements;

[0034] The above-mentioned various mechanisms cooperate with each other. During bending, loading is carried out, and preheating and drying are carried out simultaneously, reducing waiting time and realizing continuous production. Brief Description of the Drawings

The positions of the conveying mechanism 1 and the water bath bending and shaping mechanism 3 are symmetrical on both sides of the rotating mechanism 4. The conveying mechanism 1, the water bath bending and shaping mechanism 3 and the two preheating and drying mechanisms 2 are all located below the corresponding indexing mechanisms 5;

The rotating mechanism 4 cooperates with the clamping mechanism 6 to send the wood products into the water bath bending and shaping mechanism 3. In a water bath environment, the wood is bent into the required arc shape. At the same time, the clamping mechanism 6 of the indexing mechanism 5 directly above the conveying mechanism 1 repeats the above clamping process, starting to clamp the wood products on the conveying mechanism 1 until the clamping mechanism 6 is fully loaded.

A movable screw one 42 is screwed on the shaping base plate 39. The end of the movable screw one 42 abuts against the positioning frame 40.

[0063] In this embodiment, according to the size and shape of the wooden product, the position of the telescopic sleeve rod 45 is adjusted, and the position of the telescopic sleeve rod 45 is locked and fixed through the movable screw two 38, thereby determining the position of the rotating roller 39. According to the size and shape of the wooden product, the position of the positioning frame 40 is slidably adjusted, and then the position of the positioning frame 40 is locked and fixed through the movable screw one 42;

[0064] The electric gripper 16 grips the wooden product and moves it downward, causing the wooden product to pass through between the rotating roller 39 and the fixed roller 46 at the corresponding position. The wooden product is placed between the fixed roller 46 and the rotating roller 39, and the positioning frame 40 positions the wooden product. At this time, the second cylinder 38 pushes the rack 41 to move, the rack 41 drives the gear 44 to rotate, the gear 44 slowly rotates on the transmission rod 43, the gear 44 drives the telescopic sleeve rod 45 to rotate, thereby driving the rotating roller 39 to rotate. The rotating roller 39 slowly rotates with the fixed roller 46 as the center, and then bends the wooden product into the required arc shape.

[0065] The working principle of the present invention: According to the size and shape of the wooden product, adjust and replace the size and shape of the gripper stopper 18. According to the size and shape of the wooden product, adjust the position of the telescopic sleeve rod 45, lock and fix the position of the telescopic sleeve rod 45 through the second movable screw 38, and then determine the position of the rotating roller 39. According to the size and shape of the wooden product, slide and adjust the position of the positioning frame 40, and then lock and fix the position of the positioning frame 40 through the first movable screw 42;

[0066] Place the wooden products to be processed on the roller conveyor 19 in sequence. The hot air enters the air guide box 21 through the first hot air connector 22, and the air guide box 21 performs a primary preheating treatment on the wooden products to be processed. The wooden products to be processed are conveyed to the discharge chute 24 through the guide plate 23. The wooden products to be processed correspond to the position of the indexing mechanism 5 and are located directly below one of the clamping mechanisms 6. At this time, the wooden products to be processed are placed vertically. The driving shaft of the cam divider 13 drives the lower rotating table two 17 and the indexing plate 15 to rotate intermittently. First, rotate 60 degrees clockwise in sequence for one week, and rotate counterclockwise 60 degrees in the next week for one week. The purpose is to facilitate the layout of the wires. The indexing plate 15 drives the six circumferentially evenly distributed clamping mechanisms 6 to rotate, so that the electric gripper 16 corresponds to the wooden products on the conveying mechanism 1 up and down. According to different height requirements, the lifting hydraulic cylinder 7 drives the indexing mechanism 5 to move downward, the electric push rod 14 drives the electric gripper 16 to move downward, the electric gripper 16 clamps the wooden products to be processed, and after the clamping mechanism 6 clamps the wooden products, it rises to the original position. Rotate the next clamping mechanism 6 through the indexing mechanism 5 and repeat the above clamping process until all the clamping mechanisms 6 on the indexing mechanism 5 are fully loaded;

[0067] The driving shaft of the rotating motor 11 drives the rotating table 8 to rotate intermittently 90 degrees clockwise, and then drives the rotating frame 12 to rotate through the rotating table 8, driving the fully loaded transfer mechanism 5 to rotate to the top of one of the preheating and drying mechanisms 2, and the rotating mechanism 4 cooperates with the clamping mechanism 6 to send the wood product into the preheating and drying mechanism 2. The wood product after one preheating enters the box through the avoidance port 28 at the top of the preheating and drying box 27, and the hot air enters the preheating and drying box 27 through the hot air joint 26, and the wood product is preheated for the second time to facilitate subsequent bending. After the wood product is preheated, the electric clamp 16 rises and drives the wood product after the second preheating treatment to leave the preheating and drying box 27 through the avoidance port 28. The rotating mechanism 4 rotates clockwise again 90 degrees, and the fully loaded transfer mechanism 5 is rotated to the top of the water bath bending and shaping mechanism 3. The rotating mechanism 4 cooperates with the clamping mechanism 6 to send the wood product into the water bath bending and shaping mechanism 3, and firstly, the water injection joint 31 is used to inject water into the water bath bending and shaping mechanism 3. The bending and shaping water tank 30 is filled with water until the water submerges the bending and shaping component 36, and then the water is stopped. The heating base 29 heats the water in the water tank to make the water reach the set temperature to form a hot water bath environment. The electric clamp 16 clamps the wooden product and enters the water tank through the avoidance port 2 32 at the top of the bending and shaping water tank 30, so that the wooden product passes between the rotating roller 39 and the fixed roller 46 at the corresponding position. The wooden product is placed between the fixed roller 46 and the rotating roller 39. The positioning frame 40 plays a role in positioning the wooden product. At this time, the cylinder 2 38 pushes the rack 41 to move, and the rack 41 drives the gear 44 to rotate. The gear 44 rotates slowly on the transmission rod 43, and the gear 44 drives the telescopic sleeve rod 45 to rotate, thereby driving the rotating roller 39 to rotate. The rotating roller 39 rotates slowly with the fixed roller 46 as the center of the circle, and then the wooden product is bent into the desired arc-shaped wooden product. After the processing is completed, the bent and shaped wooden product is separated from the bending and shaping water tank 30 through the avoidance port 2 32;

[0068] At the same time, the clamping mechanism 6 of the transfer mechanism 5 located directly above the conveying mechanism 1 repeats the above clamping process and starts to clamp the wooden products on the conveying mechanism 1 until the clamping mechanism 6 is fully loaded. After the wooden products in the water bath bending and shaping mechanism 3 are bent, the rotating mechanism 4 rotates 90 degrees counterclockwise to transfer the fully loaded bent wooden products on the transfer mechanism 5 back to the preheating and drying mechanism 2. The bent and shaped wooden products enter the preheating and drying box 27 through the avoidance port 28 at the top of the preheating and drying box 27, and the hot air enters the preheating and drying box 27 through the hot air joint 26. , the wood products are dried, and the dried wood products are directly placed in the preheating drying box 27. The wood products slide down along the inclined sliding roller frame under the action of gravity and reach the discharge port. Finally, the dried shaped wood products are taken out, and another transfer mechanism 5 full of unbent wood products is rotated to another preheating drying mechanism 2, and the above secondary preheating treatment is repeated. After the preheating is completed, the rotating mechanism 4 is rotated counterclockwise by 90 degrees, and the transfer mechanism 5 is rotated to the top of the water bath bending and shaping mechanism 3, and the above process is repeated;

[0069] During the heating and bending processes, there is a large amount of steam inside the water bath bending and shaping mechanism 3. The steam is discharged through the steam outlet pipe joint 33, reaches the filter, and the moisture in the steam is removed through the filter to obtain hot air. The hot air is extracted by the exhaust fan and then conveyed to the first hot air joint 22 and the hot air joint 26 through the air outlet of the exhaust fan to perform the above-mentioned primary preheating, secondary preheating, and drying processes on the wood products.

[0070] In summary, the conveying mechanism 1 continuously conveys the wood products and places them vertically.

[0071] The rotating mechanism 4, the indexing mechanism 5, and the clamping mechanism 6 cooperate to quickly grab and transfer the wood products. At the same time, in cooperation with the water bath bending and shaping mechanism 3, they perform bending and shaping on the wood products, and in cooperation with the preheating and drying mechanism 2, they perform preheating and drying on the wood products.

[0072] The water bath bending and shaping mechanism 3, the conveying mechanism 1, and the preheating and drying mechanism 2 cooperate. The steam of the water bath bending and shaping mechanism 3 is processed and then conveyed to the conveying mechanism 1 and the preheating and drying mechanism 2 to perform preheating and drying on the wood products, realizing the recycling of resources, reducing energy consumption, improving energy utilization efficiency, and meeting the environmental protection requirements.

[0073] The above-mentioned mechanisms operate in coordination. Loading is carried out during bending, and preheating and drying are carried out simultaneously, reducing waiting time and realizing continuous production.
