Description

Technical Field

[0001] This utility model belongs to the field of board production technology, and specifically refers to a tape application mechanism for a wood board bending equipment. Background Technology

[0002] Wood board bending equipment is used to bend and shape wood boards. It is a key piece of equipment for realizing complex curved surface shapes. For example, the utility model patent with application number 201621160467.3 discloses a bending and forming machine, which has the following components arranged from front to back on its base: a grooving mechanism, a first gluing mechanism, a feeding mechanism and a forming mechanism.

[0003] The aforementioned bending forming machine does not treat the board material before grooving. During subsequent forming and bending, the bending point is prone to cracking due to bending deformation, affecting the quality of the bent board and even causing the board material to jam during transportation, thus affecting the overall production efficiency of the board bending equipment. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a tape application mechanism for a wood board bending equipment that can avoid cracking at the bending point during the bending process and improve the bending effect and production efficiency.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A tape-applying mechanism for a wood bending machine is characterized by: a working box, the upper side of which is a worktable for the wood board to pass through laterally, an operating window for tape to extend from the worktable, a winding roller, a front roller, a rear roller, and scissors inside the working box, the axial directions of the winding roller, the front roller, and the rear roller are all longitudinal, the front roller is located above the tape winding roller, the upper end of the rear roller is higher than the worktable, the tape wound on the winding roller first passes through the front roller and then through the rear roller to press and fix the tape to the wood board, and the scissors are located between the front roller and the rear roller and can cut the tape.

[0007] The tape in this tape application mechanism comprises a substrate layer and an adhesive layer. This invention uses a rear roller to precisely press and fix the tape onto the area of ​​the wood board to be bent before bending. The substrate layer of the tape effectively enhances the tensile strength of the wood board at the bending point, while the adhesive layer fills the gaps between the wood fibers, significantly dispersing bending stress. This structure directly solves the problem of cracking caused by bending deformation of the wood board, greatly improving the yield rate and product strength of bending and forming. Simultaneously, it avoids the situation where cracked debris obstructs the equipment, ensuring smooth transport of the wood board in subsequent processing steps, thereby significantly improving overall production efficiency.

[0008] In the tape application mechanism of the aforementioned wood bending equipment, a movable roller is provided between the front roller and the scissors, and the movable roller can move back and forth vertically.

[0009] This tape-applying mechanism features a movable roller that can reciprocate vertically. After tape is applied to a wooden board and the tape is cut, the broken tape end hangs on the movable roller. When the next wooden board moves above the movable roller, it is driven to move upward so that the tape adheres to the area of ​​the wooden board to be bent, thus achieving automatic tape application for each wooden board.

[0010] In the tape-applying mechanism of the aforementioned wood bending equipment, a first scissor drive component is provided inside the working box to drive the scissors to move longitudinally.

[0011] The first scissor drive component is set to move the scissors longitudinally to avoid interference between the scissors and the tape during the tape application process. When cutting is required, the scissors move to the cutting position to perform the cutting action. The structure is simple and highly stable.

[0012] In the tape-applying mechanism of the aforementioned wood bending equipment, the scissors include a fixed blade and a movable blade. The fixed blade is located above the movable blade. The fixed blade and the scissor body are fixedly connected to the scissor bracket. A second scissor drive is provided below the movable blade to drive the movable blade to move upward and achieve the cutting action.

[0013] This tape-applying mechanism employs a scissor structure with the fixed blade on top and the moving blade on the bottom. A second scissor drive pushes the moving blade upwards to achieve the cut, resulting in a downward clamping force on the tape at the moment of cutting. This design effectively prevents the tape from lifting or sticking to the blades during cutting, ensuring a clean and crisp cut, improving the success rate of cutting and the quality of tape adhesion at the ends, and reducing downtime caused by cutting malfunctions.

[0014] In the tape application mechanism of the aforementioned wood bending equipment, both the scissors and the second scissor drive are mounted on the mounting plate. The first scissor drive is connected to the mounting plate and drives the mounting plate to reciprocate longitudinally.

[0015] The scissors and the second scissor drive are integrated on a longitudinally movable mounting plate and driven by the first scissor drive. This integrated design simplifies the motion mechanism, ensures the synchronization and stability of the scissor assembly movement, reduces the complexity of equipment debugging and maintenance, extends the life of key components, and helps maintain the long-term efficient operation of the equipment.

[0016] In the tape application mechanism of the aforementioned wood bending equipment, the movable roller is rotatably connected to the movable support via a movable shaft, and the lower end of the movable support is provided with a movable roller drive component that drives the movable support to move vertically; the winding roller is rotatably connected to the winding support via a winding shaft, and the lower end of the winding support is provided with a winding roller drive component that drives the winding support to move vertically.

[0017] This tape-applying mechanism, through independent drive components for the movable roller and the winding roller, allows for precise control of the height adjustment stroke of the movable roller and the tape feeding height of the winding roller. This structure enables modular and independent adjustment of the tape conveying and control system, optimizes the coordination of tape release and continuous application, ensures automatic tape application, and improves system adaptability and stability.

[0018] In the tape application mechanism of the aforementioned wood bending equipment, there are a base plate and a horizontal support plate. The horizontal support plate is fixed vertically to the base plate. The movable roller drive is located on the right side of the horizontal support plate, and the winding roller drive is located on the left side of the horizontal support plate. The front roller is rotatably mounted on the left side of the front part of the horizontal support plate. The horizontal support plate is provided with a movable window through which a movable rotating shaft can pass and move vertically.

[0019] The tape application mechanism uses mutually perpendicular base plates and horizontal support plates to provide a stable mounting foundation for the movable roller drive and winding roller drive. The movable window design ensures smooth lifting and lowering of the movable shaft. This layout optimizes load distribution, enhances the overall rigidity and vibration stability of the mechanism, provides a reliable mechanical platform for high-precision roller movement and tape application, and extends the service life of the equipment.

[0020] In the tape application mechanism of the aforementioned wood bending equipment, a longitudinal support plate perpendicular to the base plate is provided. The longitudinal support plate is located behind the transverse support plate and is perpendicular to the transverse support plate. The longitudinal support plate is provided with a plurality of strip holes, the length direction of which is vertical. A connector is connected to the right side of the rear roller. The connector is adjustablely connected to the strip holes on the main support plate by fasteners.

[0021] In this tape-applying mechanism, the longitudinal support plate, together with the base plate and the transverse support plate, forms a rigid frame, which optimizes load distribution and enhances the overall rigidity and vibration stability of the mechanism. By setting vertical strip holes on the longitudinal support plate, and adjusting the installation height of the rear roller with connectors and fasteners, the pressing position of the rear roller can be adapted to wood boards of different thicknesses. This structure greatly improves the versatility of the equipment, ensuring that all types of wood boards can obtain a uniform and sufficient tape pressing effect, guaranteeing crack prevention performance from the source, and reducing equipment adjustment downtime caused by changes in wood board specifications.

[0022] In the tape application mechanism of the aforementioned wood bending equipment, a slider is provided on the lower side of the base plate, and a slide rail that cooperates with the slider is provided at the bottom of the working box. The slide rail is arranged longitudinally, and the slider can drive the base plate to move back and forth longitudinally.

[0023] A slider is installed on the underside of the base plate, which works in conjunction with the longitudinal slide rail of the base. This allows the various components on the base plate to adjust the position of the tape according to the actual bending requirements, ensuring that the tape can adhere to the position of the wooden board to be bent, thereby improving the yield rate.

[0024] Compared with the prior art, the technical effects of this utility model are as follows:

[0025] This invention utilizes a rear roller to precisely press and fix adhesive tape onto the area of ​​the wood board to be bent before bending. The base layer of the tape effectively enhances the tensile strength of the wood board at the bending point, while the adhesive layer fills the gaps between the wood fibers, significantly dispersing bending stress. This structure directly solves the problem of cracking caused by bending deformation of the wood board, greatly improving the yield rate and product strength of bending and forming. Simultaneously, it avoids the situation where cracked debris obstructs the equipment, ensuring smooth conveyance of the wood board in subsequent processing steps, thereby significantly improving overall production efficiency.

[0033] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0034] The tape-applying mechanism of this wood board bending equipment includes a work box 1. The upper side of the work box 1 is a worktable 11 for the wood board to pass through laterally. An operating window 111 for the tape to extend is provided on the worktable 11. Inside the work box 1 are a winding roller 2, a front roller 3, a rear roller 4, and a shear 5. The axial directions of the winding roller 2, the front roller 3, and the rear roller 4 are all longitudinal. The front roller 3 is located above the tape winding roller 2, and the upper end of the rear roller 4 is higher than the worktable 11. The tape wound on the winding roller 2 first passes through the front roller, then through the rear roller 4, pressing the tape firmly to the wood board. The shear 5 is located between the front roller 3 and the rear roller 4 and can cut the tape. The tape in this tape-applying mechanism includes a substrate layer and an adhesive layer. This invention utilizes a rear roller 4 to precisely press and fix adhesive tape onto the area of ​​the wood board to be bent before bending. The base layer of the tape effectively enhances the tensile strength of the wood board at the bending point, while the adhesive layer fills the gaps between the wood fibers, significantly dispersing bending stress. This structure directly solves the problem of cracking caused by bending deformation of the wood board, greatly improving the yield rate and product strength of bending and forming. At the same time, it avoids the situation of cracked debris blocking the equipment, ensuring the smooth transport of the wood board in subsequent processing steps, thereby significantly improving overall production efficiency.

[0035] like Figure 2-5As shown, a movable roller 6 is provided between the front roller 3 and the scissors 5, and the movable roller 6 can move back and forth vertically; a first scissor drive member 54 is provided in the working box 1 to drive the scissors 5 to move longitudinally; the scissors 5 includes a fixed blade 51 and a movable blade 52, the fixed blade 51 is located above the movable blade 52, the fixed blade 51 and the main body of the scissors 5 are fixedly connected to the scissors 5 bracket, and a second scissor drive member 55 is provided below the movable blade 52 to drive the movable blade 52 to move upward to realize the cutting action; the scissors 5 and the second scissor drive member 55 are both mounted on the mounting plate 53, and the first scissor drive member 54 is connected to the mounting plate 53 and drives the mounting plate 53 to move back and forth longitudinally.

[0036] This tape-applying mechanism features a movable roller 6 that can reciprocate vertically. After tape is applied to a wooden board and the tape is cut, the broken tape end hangs on the movable roller 6. When the next wooden board moves above the movable roller 6, the roller 6 is driven upward to adhere the tape to the area of ​​the board to be bent, thus achieving automatic tape application for each wooden board. A first scissor drive 54 is provided to drive the scissors 5 to move longitudinally, preventing interference between the scissors 5 and the tape during the tape application process. When cutting is required, the scissors 5 move to the cutting position to perform the cutting action. The structure is simple and highly stable. This tape-applying mechanism uses a scissors 5 structure with the fixed blade 51 on top and the movable blade 52 on the bottom. With the help of the second scissor drive 55, the movable blade 52 is pushed upward to achieve cutting, so that the tape is subjected to downward pressure at the moment of cutting. This design effectively prevents the tape from lifting or sticking to the blade during cutting, ensuring clean and crisp cutting, improving the success rate of cutting and the adhesion quality of the tape ends, and reducing downtime caused by cutting failures. The scissors 5 and the second scissor drive 55 are integrated onto a longitudinally movable mounting plate 53, driven uniformly by the first scissor drive 54. This integrated design simplifies the motion mechanism, ensures the synchronization and stability of the scissors 5 assembly movement, reduces the complexity of equipment debugging and maintenance, extends the lifespan of key components, and helps maintain long-term efficient operation of the equipment. The first scissor drive 54 and the second scissor drive 55 are either cylinders or drive motors.

[0037] like Figure 2-5As shown, the movable roller 6 is rotatably connected to the movable support 62 via a movable shaft 61. A movable roller drive component 63, which drives the movable support 62 to move vertically, is located at the lower end of the movable support 62. The winding roller 2 is rotatably connected to the winding support 22 via a winding shaft 21. A winding roller drive component 23, which drives the winding support 22 to move vertically, is located at the lower end of the winding support 22. This tape-applying mechanism, through independent movable roller drive components 63 and winding roller drive components 23, can precisely control the height adjustment stroke of the movable roller 6 and the tape feeding height of the winding roller 2, respectively. This structure achieves modular independent adjustment of the tape conveying and control system, optimizes the coordination of tape release and continuous application, ensures automatic tape application, and improves system adaptability and stability. The aforementioned movable roller drive component 63 and winding roller drive component 23 are either cylinders or drive motors.

[0038] like Figure 1-6 As shown, the mechanism includes a base plate 7 and a horizontal support plate 8. The horizontal support plate 8 is fixed perpendicularly to the base plate 7. The movable roller drive 63 is located on the right side of the horizontal support plate 8, and the winding roller drive 23 is located on the left side of the horizontal support plate 8. The front roller 3 is rotatably mounted on the left side of the front part of the horizontal support plate 8. The horizontal support plate 8 has a movable window 81 for the movable shaft 61 to pass through and move vertically. This tape-applying mechanism uses the mutually perpendicular base plate 7 and horizontal support plate 8 to provide a stable mounting base for the movable roller drive 63 and the winding roller drive 23. The movable window 81 design ensures the smooth lifting and lowering of the movable shaft 61. This layout optimizes load distribution, enhances the overall rigidity and vibration stability of the mechanism, provides a reliable mechanical platform for high-precision roller movement and tape application, and extends the service life of the equipment.

[0039] Furthermore, a vertical longitudinal support plate 9 is provided on the base plate 7, located behind and perpendicular to the transverse support plate 8. The longitudinal support plate 9 has several strip-shaped holes 91, with the length of the holes 91 running vertically. A connector 41 is connected to the right side of the rear roller 4, and the connector 41 is adjustablely connected to the strip-shaped holes 91 on the main support plate via fasteners. In this tape-applying mechanism, the longitudinal support plate 9, together with the base plate 7 and the transverse support plate 8, forms a rigid frame, optimizing load distribution and enhancing the overall rigidity and vibration stability of the mechanism. By providing vertical strip-shaped holes 91 on the longitudinal support plate 9, and adjusting the installation height of the rear roller 4 with the connector 41 and fasteners, the pressing position of the rear roller 4 can be adapted to wood boards of different thicknesses. This structure significantly improves the versatility of the equipment, ensuring that all types of wood boards can achieve uniform and sufficient tape pressing, guaranteeing crack prevention performance from the source, and reducing equipment downtime due to changes in wood board specifications.

[0040] Furthermore, a slider 71 is provided on the lower side of the base plate 7, and a slide rail 12 that cooperates with the slider 71 is provided on the bottom of the work box 1. The slide rail 12 is arranged longitudinally, and the slider 71 can drive the base plate 7 to move back and forth longitudinally. The slider 71 on the lower side of the base plate 7, which cooperates with the longitudinal slide rail 12 of the base, allows the various components on the base plate 7 to adjust the position of the adhesive tape according to the actual bending requirements, ensuring that the adhesive tape can be adhered to the position of the wooden board to be bent, thereby improving the yield rate.

[0041] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection defined by the claims of the present utility model.
