Description

Technical Field

[0001] This utility model belongs to the technical field of wood processing equipment, specifically a wood processing anti-warping device. Background Technology

[0002] In the modern architectural decoration and furniture manufacturing industry, wood panels, with their natural texture, excellent processing performance, and wide applicability, have become an indispensable basic material. From the interior decoration of high-end residences to the production of various furniture, the processing quality of wood panels directly determines the aesthetic appearance and performance of the final product. Taking custom furniture as an example, high-quality wood panels ensure the stability of the cabinet structure and the smoothness of the surface, thereby enhancing the user experience and the product's market competitiveness.

[0003] However, edge warping has always been a technical challenge hindering the development of the wood panel industry. Edge warping refers to the upward or downward bending deformation of the edges of a wood panel after processing steps such as drying, cutting, and sanding. This phenomenon is closely related to the natural characteristics of wood, processing parameters, and environmental factors. As a porous and anisotropic material, improper handling during processing can exacerbate internal stress, leading to edge warping. Edge warping reduces processing precision, making it difficult to meet design requirements during splicing and assembly, and increasing assembly difficulty and manual adjustment costs.

[0004] In traditional wood processing, pressure is applied to the wood during processing. This can cause the front of the wood to warp due to localized stress when the pressure is suddenly released. Existing technology addresses this by manually moving the warped wood to a location and pressing it for a period of time to relieve the localized stress before moving it to the next processing step. This reduces processing efficiency. Therefore, a wood processing anti-warping device has been invented to address this defect. Utility Model Content

[0005] To address the technical problem of reduced processing efficiency caused by the need to remove and process wooden boards during stress relief, this utility model provides a device for preventing warping during wooden board processing.

[0006] This utility model is achieved through the following technical solution.

[0007] A device for preventing warping of wood panels includes a mounting frame, an anti-warping mechanism, and a conveying mechanism. The anti-warping mechanism includes an upper frame, which is fixedly mounted on the mounting frame. A pressure frame is fixedly mounted on the side of the upper frame, which is located above the mounting frame. The side of the pressure frame facing the conveying mechanism is inclined, and the height of the inclined surface of the pressure frame gradually increases along the direction away from the upper frame.

[0008] The conveying mechanism is mounted on the mounting frame and located between the mounting frame and the pressure frame. The conveying mechanism is able to transport the planks to the bottom of the pressure frame.

[0009] This device is installed at the rear of the wood cutting machine. The conveying mechanism transports the wood boards processed in the previous step (such as the cutting machine) backward. When the warped edge of the wood board comes into contact with the guide slope of the pressure frame, the wood board slides down the slope of the pressure frame. The conveying mechanism continues to drive the wood board to slide along the lower part of the pressure frame, thereby pressing the wood board with the pressure frame. This effectively prevents the wood board from warping. The wood board can eliminate local stress during transportation. The wood board is output from the rear of this device, which can realize continuous processing of wood boards, avoid the need to carry and shape (press) the wood boards back and forth, save manpower, and effectively improve work efficiency.

[0010] A further improvement of this utility model is that four mounting rods are symmetrically fixedly installed on the lower side of the upper frame, and the four mounting rods are fixedly installed on both sides of the mounting frame.

[0011] A further improvement of this utility model is that there are two pressure frames, which are symmetrically fixedly installed on one side of the upper frame, and a connecting rod is fixedly installed between the two pressure frames.

[0012] A further improvement of this utility model is that the overall cross-section of the side frame is a right trapezoid. The side frame includes a long rod, a diagonal rod, and a short rod connected in sequence. The long rod is located above the short rod and its length is greater than that of the short rod. The long rod and the short rod are connected by the diagonal rod. The ends of the long rod and the short rod away from the diagonal rod are level and are both fixedly installed on the side of the upper frame facing the conveying mechanism. The connection between the diagonal rod and the long rod and the short rod is provided with rounded corners. The lower side of the diagonal rod and the connection with the long rod and the short rod form a guide slope.

[0013] A further improvement of this utility model is that the conveying mechanism includes a belt and a transmission assembly, the transmission assembly is mounted on the mounting frame, the transmission assembly is connected to the belt, and the belt is located between the mounting frame and the upper frame.

[0014] A further improvement of this utility model is that the transmission assembly includes four bearing seats, which are symmetrically fixedly mounted on the mounting frame. A transmission rod is rotatably mounted between two bearing seats, and a pulley is fixedly mounted at both ends of each transmission rod. The two pulleys are connected by a belt to form a belt drive.

[0015] A further improvement of this utility model is that a motor is fixedly mounted on the mounting bracket, the motor is located below the pulley, a sprocket is fixedly mounted on the output end of the motor, and a sprocket is also fixedly mounted on the outer surface of a transmission rod. The two sprockets are connected by a chain.

[0016] A further improvement of this utility model includes a discharge mechanism. Two sets of discharge mechanisms are symmetrically installed on both sides of the mounting frame. Each discharge mechanism includes a tilting plate and a tilting assembly. The tilting plate is rotatably mounted on the mounting frame and located on the side of the belt. The tilting assembly is mounted on the side of the mounting frame and connected to the tilting plate. The tilting plate is located below the upper frame. The tilting assembly includes a first fixed seat, which is fixedly mounted on the side of the mounting frame. An electric cylinder is rotatably mounted on the first fixed seat. A transmission rod is fixedly mounted on the telescopic end of the electric cylinder. A second fixed seat is rotatably mounted on the transmission rod and fixedly mounted on the lower side of the tilting plate.

[0017] The advantages of this invention compared to the prior art are as follows: This invention uses a belt to transport the pre-processed wooden board to the pressing frame. When the front part of the wooden board with warped edges contacts the inclined surface of the pressing frame, the front part of the wooden board slides down along the inclined surface of the pressing frame. When the front part of the wooden board slides to the bottom of the pressing frame, the belt continues to drive the wooden board to slide along the lower part of the pressing frame. The pressing frame presses down on the wooden board, thereby eliminating the local stress of the wooden board during transportation, thus saving the manual handling process, saving working time and effectively improving work efficiency.

[0028] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0029] As attached Figure 1 and attached Figure 2 As shown, this utility model discloses a device for preventing warping of wood panels, including a mounting frame 1, an anti-warping mechanism 2 connected and mounted on the mounting frame 1, and a conveying mechanism 3 capable of supporting and conveying the wood panels; the anti-warping mechanism 2 includes an upper frame 201 fixedly connected and mounted to the upper part of the mounting frame 1, and a pressing frame 202 fixedly connected and mounted on the lower side of the upper frame 201, which corresponds vertically to the conveying mechanism 3 and is capable of pressing and shaping the wood panels, and the lower edge of the front end of the pressing frame 202 is provided with a guide slope.

[0030] This device is installed at the rear of the wood cutting machine. The conveying mechanism 3 transports the wood boards processed in the previous step (such as the cutting machine) backward. When the warped edge of the wood board comes into contact with the guide slope of the pressure frame 202, the wood board slides down the guide slope of the pressure frame 202. The conveying mechanism 3 continues to drive the wood board to slide along the lower part of the pressure frame 202, thereby pressing the wood board through the pressure frame 202, effectively preventing the wood board from warping. The wood board can eliminate local stress during transportation. The wood board is output from the rear of this device, which can realize continuous processing of wood boards, avoid the need to carry and shape (press) the wood boards back and forth, save manpower, and effectively improve work efficiency.

[0031] As attached Figure 3 - Appendix Figure 8 As shown, this utility model discloses an unloading mechanism 4, which includes a tilting plate 401 and a first fixed seat 402. The tilting plate 401 is rotatably mounted on the mounting frame 1 and is located on the side of the belt 302 and below the upper frame 201. The first fixed seat 402 is fixedly mounted on the side of the mounting frame 1. An electric cylinder 405 is rotatably mounted on the first fixed seat 402. A transmission rod 403 is fixedly mounted on the telescopic end of the electric cylinder 405. A second fixed seat 404 is rotatably mounted on the transmission rod 403 and is fixedly mounted on the lower side of the tilting plate 401. When the motor and the electric cylinder 405 are started, the electric cylinder 405 drives the second fixed seat 404 to move through the transmission rod 403. The second fixed seat 404 drives the tilting plate 401 to rotate. When the acute angle between the upper end face of the tilting plate 401 and the upper end face of the mounting frame 1 is 30 degrees, the electric cylinder 405 stops working, and the waste material cut off in the previous processing step falls through the tilting plate 401.

[0032] As attached Figure 1 - Appendix Figure 6 As shown, this utility model discloses an anti-warping mechanism 2, which includes an upper frame 201. A pressure frame 202 is fixedly installed on the side of the upper frame 201. The upper frame 201 is fixedly connected to the mounting frame 1. The pressure frame 202 is located above the mounting frame 1. The distance between the pressure frame and the conveying mechanism is slightly greater than the thickness of the wooden board. The lower surface (pressing surface) of the pressure frame is a smooth surface to ensure low friction. Four mounting rods 203 are symmetrically fixedly installed on the lower side of the upper frame 201. The four mounting rods 203 are fixedly installed on both sides of the mounting frame 1.

[0033] As attached Figure 1 - Appendix Figure 5 As shown, this utility model discloses a pressing frame 202, which includes two side frames symmetrically fixedly installed on the lower side of the upper frame 201. A connecting rod 204 is fixedly installed between the two side frames. The overall cross-section of the side frame is a right trapezoid. The side frame includes a long rod, a diagonal rod, and a short rod connected in sequence. The long rod is located above the short rod and its length is greater than that of the short rod. The long rod and the short rod are connected by the diagonal rod. The ends of the long rod and the short rod away from the diagonal rod are level and fixedly installed on the side of the upper frame 201 facing the conveying mechanism 3. The diagonal rod is provided with rounded corners at the connection points with the long rod and the short rod. The lower side of the diagonal rod and the connection points with the long rod and the short rod form a guide slope. The surface of the guide slope is smooth to ensure that the front end of the warped wooden board can slide along the guide slope to the pressing surface. The acute angle between the lower side of the diagonal rod and the upper surface of the upper frame 201 is 30 degrees to 60 degrees. The distance between the opposite ends of the two side frames is equal to the width of the wooden board.

[0034] As attached Figure 2 - Appendix Figure 6As shown, this utility model discloses a conveying mechanism 3, which includes a belt 302 and four bearing seats 303. The belt 302 is located between the mounting frame 1 and the upper frame 201. The four bearing seats 303 are symmetrically fixedly installed on the mounting frame 1. A transmission rod 304 is rotatably installed between two bearing seats 303. A pulley 301 is fixedly installed at both ends of each transmission rod 304. The two pulleys 301 are connected by a belt 302 to form a belt drive. Multiple support rods 306 are fixedly installed on the mounting frame 1. The upper surface of all support rods 306 is slidably connected to the upper part of the belt 302. The support rods 306 support the belt 302. The support rods 306 are located between the pressure frame 202 and the mounting frame 1.

[0035] A motor is fixedly mounted on the mounting bracket 1, located below the pulley 301. A sprocket 305 is fixedly mounted on the motor's output end, and another sprocket 305 is fixedly mounted on the outer surface of a transmission rod 304. The two sprockets 305 are connected by a chain. The motor drives the sprockets 305 to rotate via the chain, and the sprockets 305 drive the pulley 301 to rotate via the transmission rod 304. The pulley 301 drives the belt 302 to move, which in turn moves the cut wooden boards. The processed wooden boards are moved by the belt 302, and the wood is transported by the belt 301. The board is fed to the pressure frame 202. When the front part of the board, which has warped, contacts the inclined surface of the pressure frame 202, the front part of the board slides down along the inclined surface of the pressure frame 202. When the front part of the board slides to the bottom of the pressure frame 202, the belt 302 continues to drive the board to slide along the lower part of the pressure frame 202. The lower part of the pressure frame 202 presses down on the board, thereby eliminating the local stress of the board during transportation. This saves manual handling, saves working time and improves work efficiency. After the board leaves the pressure frame 202, the belt 302 continues to transport the board to the next process.

[0036] The working principle of this utility model is as follows.

[0037] (i) The motor and electric cylinder 405 start. The electric cylinder 405 drives the second fixed seat 404 to move through the transmission rod 403. The second fixed seat 404 drives the flip plate 401 to rotate. When the acute angle between the upper end face of the flip plate 401 and the upper end face of the mounting frame 1 is 30 degrees, the electric cylinder 405 stops working. The motor drives the sprocket 305 to rotate through the chain. The sprocket 305 drives the pulley 301 to rotate through the transmission rod 304. The pulley 301 drives the belt 302 to move. The belt 302 drives the cut wooden board to be transported. The waste material cut from the previous process falls through the flip plate 401.

[0038] (ii) The processed wooden board is sent to the pressing frame 202. When the front part of the wooden board with warped edges comes into contact with the inclined surface of the pressing frame 202, the front part of the wooden board slides down along the inclined surface of the pressing frame 202. When the front part of the wooden board slides to the bottom of the pressing frame 202, the belt 302 continues to drive the wooden board to slide along the lower part of the pressing frame 202. The lower part of the pressing frame 202 presses the wooden board, thereby eliminating the local stress of the wooden board during transportation, thus saving the manual handling process, saving working time and improving work efficiency. After the wooden board is removed from the pressing frame 202, the belt 302 continues to transport the wooden board to the next process.
