Abstract

The application discloses a cutting and pressing device for processing composite bamboo-wood floor and a use method thereof, and relates to the field of wood floor cutting. The cutting and pressing device comprises a cutting device main body, a connecting frame, a supporting frame, an adjusting frame, a side pushing assembly and a pressure assembly.

Through single-cylinder driving combined with the connecting rod and the adjusting frame linkage mechanism, it is ensured that the two side contact plates can move towards the center and press synchronously at equal distances, so as to adapt to different floor widths, and the downward pressure of the contact rollers is automatically converted into stable lateral partial pressure on the edges of the floor.

Description

Technical Field

[0001] This invention relates to the field of wood flooring cutting, and particularly to a pressure cutting device for processing composite bamboo wood flooring and its usage method. Background Technology

[0002] Composite bamboo flooring is a green building material that combines the high stability of bamboo with the beautiful texture of solid wood.

[0003] In existing technologies, composite bamboo flooring is typically cut using a standard woodworking table saw or a cutting device with a one-way clamping mechanism.

[0004] In existing technologies, during the cutting process, the saw blade generates a vertically upward tearing force and a horizontal shearing force on the material.

[0005] Without effective lateral restraint, the soft surface of solid wood veneer is prone to fiber breakage in front of the blade, which seriously affects the product's appearance and joint sealing.

[0006] Furthermore, conventional clamping devices mostly apply vertical unidirectional pressure or independently control lateral pressure, which cannot form a three-dimensional constraint on the edge of the board during the cutting process. This causes the flooring to easily produce slight interlayer separation or overall warping when subjected to cutting force, resulting in non-perpendicular cuts and reduced dimensional accuracy.

[0007] Therefore, we propose a pressure cutting device and its usage method for processing composite bamboo and wood flooring to solve the above problems. Summary of the Invention

[0008] The purpose of this invention is to provide a pressing and cutting device for processing composite bamboo and wood flooring and its method of use, so as to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a pressure cutting device for processing composite bamboo flooring, comprising: The main body of the cutting device includes a cutting machine for processing composite bamboo and wood flooring. Connecting frame, used for conveying composite bamboo flooring; Two support frames are symmetrically installed on both sides of the connecting frame; An adjustment frame is slidably connected to the two support frames; Two sets of side-push assemblies are symmetrically arranged on both sides of the connecting frame. Each side-push assembly includes a side contact plate and a drive component that drives its movement, used to clamp and position the composite bamboo flooring from both sides. Pressure assembly, mounted on the adjustment frame; The side contact plate and the adjustment frame are rotatably connected by at least one connecting rod; When the driving component drives the side contact plates on both sides to move towards each other to clamp the composite bamboo and wood flooring, the connecting rod pulls the adjusting frame down along the support frame, thereby driving the pressure component to press down synchronously.

[0010] Preferably, the driving component includes a fixed base, which is fixed on the connecting frame. The side contact plate is disposed on one side of the fixed base. A sliding rod is slidably connected to the inner wall of the fixed base. One end of the sliding rod passes through the fixed base and is fixedly connected to the side contact plate. The sliding rod is used to limit the sliding stability of the side contact plate relative to the fixed base.

[0011] Preferably, the driving component further includes a push cylinder, which is installed on one side of one of the fixed seats. The output end of the push cylinder extends outward through the fixed seat. A push seat is installed at the output end of the push cylinder. The push seat is located between the side contact plate and the fixed seat, and the push seat is slidably connected to the outer peripheral wall of the sliding rod. A damper is fixedly connected between the push seat and the side contact plate.

[0012] Preferably, the pressure assembly includes a pressure cylinder mounted on the adjusting frame. The output end of the pressure cylinder is connected to a movable frame. A guide rod is fixedly connected to the bottom end of the movable frame. The guide rod is slidably connected to the inner wall of the adjusting frame. A pressure frame is fixedly connected to one end of the guide rod that passes downward through the adjusting frame. Two adjustable-gap contact rollers are provided below the pressure frame for pressing the surface of the composite bamboo and wood flooring.

[0013] Preferably, a bidirectional lead screw is rotatably connected inside the pressure frame, and two adjusting seats are threaded onto the bidirectional lead screw. The contact roller is rotatably connected to the adjusting seats via a rotating seat and a pressure main rod. A pressure support rod is rotatably connected to the pressure main rod, and an extrusion block is rotatably connected to the other end of the pressure support rod. The extrusion block is slidably connected to the inner wall of the pressure frame and is fixedly connected to a pressure spring. A positioning block is provided on one side of the extrusion block, and the positioning block is used to limit the movement of the extrusion block.

[0014] Preferably, one end of the bidirectional lead screw extends to the outside of the pressure frame and is fitted with a pulley. Adjacent pulleys are connected by a transmission belt to achieve synchronous adjustment of the spacing between the multiple contact rollers.

[0015] Preferably, the support frame has a vertical sliding groove, and the adjusting frame has sliders on both sides that slide in cooperation with the sliding groove.

[0016] Preferably, the main body of the cutting device is provided with a ventilation port, and the ventilation port is connected to an external fan through a pipe for sucking up the debris generated during cutting.

[0017] The method of using the pressure cutting device for processing composite bamboo flooring includes the following steps: S1: Place the composite bamboo flooring on the conveyor rollers of the connecting frame; S2: Start the drive unit to drive the side contact plates on both sides to move towards each other, clamp and push the composite bamboo flooring to the center position. During this process, the side contact plates pull the adjustment frame and pressure component to descend synchronously through the connecting rod. S3: The contact roller of the pressure component contacts the top surface of the composite bamboo and wood flooring, and the downward pressure increases as the adjustment frame continues to descend. At the same time, the contact roller generates a two-way pressure on the floor surface. S4: Start the conveyor rollers to feed the multi-directionally compressed composite bamboo and wood flooring into the main body of the cutting device for cutting.

[0018] Preferably, in step S2, a push cylinder drives one side contact plate, and through the linkage of the connecting rod and the adjusting frame, the two side contact plates move in opposite directions at equal distances and synchronously.

[0019] The technical effects and advantages of this invention are as follows: When the side contact plates on both sides apply a horizontal clamping force to the floor, the connecting rod will force the entire pressure assembly above to descend synchronously. This causes the contact rollers below the pressure frame to be given an expanding tendency to both sides while compacting the floor surface. The multi-directional pressure field applied in advance before cutting locks the finishing layer fibers to the bamboo base layer at the moment of cutting, thereby effectively suppressing tearing forces in the vertical and horizontal directions.

[0020] By using a single cylinder drive combined with a linkage mechanism of connecting rod and adjusting frame, it is ensured that the side contact plates on both sides can move towards the center synchronously and apply pressure at equal distances, automatically aligning the floor precisely. The spacing between the upper contact rollers can be flexibly adjusted through a bidirectional screw mechanism to adapt to different floor widths, automatically converting the downward pressure of the contact rollers into a stable lateral pressure on the edge of the floor, thus improving dimensional accuracy and processing consistency.

[0021] This invention transmits and converts power and motion through purely mechanical connecting rods, sliders, and lead screws. This design reduces the need for multiple independent cylinders and sensors, thereby lowering electrical complexity and failure rate. Attached Figure Description

[0024] The technical solutions of 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.

[0025] This invention provides, for example Figures 1-10 The composite bamboo flooring processing pressure cutting device and its usage method shown include a cutting device body 1, a connecting frame 2, a support frame 3, an adjusting frame 4, a side pushing component, and a pressure component. The main body 1 of the cutting device is equipped with a cutting machine, and support platforms 12 are provided on both sides of the main body 1 of the cutting device. The main body 1 of the cutting device is provided with a ventilation port 11. The ventilation port 11 is connected to an external fan through a pipe to remove the debris generated in the main body 1 of the cutting device from the cutting of composite bamboo and wood flooring. The connecting frame 2 is fixedly connected to the support platform 12 at the inlet of the main body 1 of the cutting device; Two support frames 3 are installed on both sides of the connecting frame 2; Adjustment frame 4 is slidably connected to the inner walls of two support frames 3.

[0026] The support frame 3 has a vertical slide groove 31, and the adjustment frame 4 has sliders 41 on both sides that slide in cooperation with the slide groove 31. The sliders 41 are slidably connected to the inner wall of the slide groove 31 to guide the stability of the adjustment frame 4 sliding on the support frame 3. Two sets of side-push components are symmetrically arranged on both sides of the connecting frame 2. The side-push components include side contact plates 5 and drive components that drive them to move, for clamping and positioning the composite bamboo flooring from both sides. The side-push assembly includes a side contact plate 5 and a fixed seat 51. The fixed seat 51 is fixedly installed on the connecting frame 2. The side contact plate 5 is located on one side of the fixed seat 51. The side contact plate 5 is used to contact the composite bamboo and wood flooring for pushing and positioning. A sliding rod 53 is slidably connected to the inner wall of the fixed base 51. One end of the sliding rod 53 passes through the fixed base 51 and is fixedly connected to the side contact plate 5. The sliding rod 53 is used to limit the sliding stability of the side contact plate 5 relative to the fixed base 51. One of the two sets of side-push components has a push cylinder 6 mounted on the side of a fixed base 51. The output end of the push cylinder 6 extends outward through the fixed base 51. A push seat 52 is mounted on the output end of the push cylinder 6. The push seat 52 is located between the side contact plate 5 and the fixed base 51. The push seat 52 is slidably connected to the outer peripheral wall of the sliding rod 53. Under the action of the sliding rod 53, it is used to limit the stability of the sliding path of the push seat 52 on the sliding rod 53. A damper 54 is fixedly connected between the push seat 52 and the side contact plate 5. The damper 54 is used to apply pressure between the side contact plate 5 and the fixed seat 51. When the composite bamboo flooring is placed on the connecting frame 2, the composite bamboo flooring is conveyed by the conveying roller connected in the connecting frame 2. The push cylinder 6 of the side push assembly drives the push seat 52 to move, pushes the side contact plate 5 on the same side through the damper 54, and drives the side contact plate 5 on the other side to move synchronously towards each other through the linkage of the connecting rod 55 and the adjusting frame 4.

[0027] At this time, the push cylinder 6 controls the push seat 52 to move. Under the action of the damper 54, the side contact plate 5 moves to the side of the composite bamboo flooring and pushes the composite bamboo flooring to move until the two side contact plates 5 contact and press the two sides of the composite bamboo flooring respectively. During the pressing process, the damper 54 extends and retracts and provides a reverse thrust to the side contact plates 5, so that the side contact plates 5 on both sides can be subjected to force to press the composite bamboo flooring and push it towards the center position. Furthermore, at least two connecting rods 55 are rotatably connected between the side contact plate 5 and the adjusting frame 4. When the push seat 52 pushes the side contact plate 5 to move toward the composite bamboo flooring through the damper 54, the side contact plate 5 moves and pulls the connecting rods 55 to rotate. Under the pull of the connecting rods 55, the adjusting frame 4 moves downward. At this time, the adjusting frame 4 slides on the inner wall of the groove 31 opened on the support frame 3 through the slider 41. Furthermore, since the adjusting frame 4 slides on the support frame 3, the adjusting frame 4 can only move vertically along the support frame 3. As the adjusting frame 4 moves, the connecting rod 55, which is rotatably connected to the two side contact plates 5, rotates at the same angle. This ensures that the side contact plates 5 on both sides of the composite bamboo flooring move along the same path, thus providing conditions for pushing the composite bamboo flooring to the center position.

[0028] Example 1: Pressure assembly, installed on adjustment frame 4, the pressure assembly includes pressure cylinder 8.

[0029] The pressure cylinder 8 is installed on the adjusting frame 4. The output end of the pressure cylinder 8 is connected to the movable frame 81. The bottom end of the movable frame 81 is fixedly connected to the guide rod 71. The guide rod 71 is slidably connected to the inner wall of the adjusting frame 4. The end of the guide rod 71 that passes through the adjusting frame 4 downwards is fixedly connected to the pressure frame 7. Two adjustable contact rollers 75 are provided below the pressure frame 7 for pressing the surface of the composite bamboo and wood flooring. The pressure frame 7 is internally rotatably connected to a bidirectional lead screw 72, which has two sets of threaded grooves with opposite directions of rotation. The pressure frame 7 is slidably connected to two sets of adjusting seats 73, which are threadedly connected to the threaded grooves. The pressure main rod 74 is rotatably connected to the lower part of the adjusting seat 73. The bottom end of the pressure main rod 74 is fixedly connected to a rotating seat 741, and a contact roller 75 is rotatably connected to the rotating seat 741. The contact roller 75 is rotatably connected to the adjusting seat 73 via the rotating seat 741 and the pressure main rod 74.

[0030] The pressure frame 7 is provided with a guide groove 711. The adjusting seat 73 and the extrusion block 77 are slidably connected in the guide groove 711 and slide in the pressure frame 7. The guide groove 711 is used to limit the movement path of the adjusting seat 73 and the extrusion block 77. A pressure support rod 76 is rotatably connected to the main pressure rod 74. A pressing block 77 is rotatably connected to the other end of the pressure support rod 76. The pressing block 77 is slidably connected to the inner wall of the pressure frame 7 and is fixedly connected to a pressure spring 78. When the contact roller 75 presses down to contact the composite bamboo and wood flooring and moves upward under force, it drives the pressure main rod 74 to rotate, which in turn compresses the pressure spring 78 through the pressure support rod 76, so that the contact roller 75 obtains partial pressure pointing to both sides of the composite bamboo and wood flooring.

[0031] A pressure spring 78 is fixedly connected to one side of the extrusion block 77, and the other side of the pressure spring 78 is fixedly connected to the pressure frame 7. A positioning block 79 is provided on one side of the extrusion block 77, and the positioning block 79 is used to limit the movement of the extrusion block 77. Example 2: One end of the bidirectional lead screw 72 extends outward through the pressure frame 7. A pulley 9 is sleeved on the outer peripheral wall of the bidirectional lead screw 72. The pulley 9 is rotatably connected to one side of the pressure frame 7 via the bidirectional lead screw 72. A transmission belt 91 is connected between adjacent pulleys 9. The pulleys 9 drive the adjacent pulleys 9 to rotate via the transmission belt 91. Under the rotation of the pulleys 9, the bidirectional lead screw 72 rotates in the pressure frame 7. Under the rotation of the bidirectional lead screw 72, the adjusting seat 73 slides along the inner wall of the pressure frame 7. Under the movement of the adjusting seat 73, the pressure main rod 74 is pulled to rotate, so that the pressure main rod 74 drives the rotating seat 741 and the contact roller 75 to move accordingly, adjusting the distance between the two contact rollers 75. This allows the contact rollers 75 to be adjusted relative to the size of the composite bamboo and wood flooring. When the contact rollers 75 are pressed down, they are pushed by the pressure main rod 74 to a suitable position on the edge of the composite bamboo and wood flooring, pressing the edge position, improving the edge stability of the composite bamboo and wood flooring during cutting, and avoiding the problem of edge chipping. When the composite bamboo and wood flooring is placed between the side contact plates 5, the push cylinder 6 is controlled to push the push seat 52 to move. Under the action of the damper 54 set between the push seat 52 and the side contact plate 5, the side contact plate 5 is pushed to contact and press the wood board, and the wood board is pushed to move towards the center position. Furthermore, the movement of the side contact plate 5 causes the connecting rod 55 to rotate, which in turn pulls the adjusting frame 4 to move. This causes the adjusting frame 4 to slide along the support frame 3, which in turn moves the other side contact plate 5. The other side contact plate 5 then causes the sliding rod 53 to slide along the fixed seat 51, allowing the side contact plate 5 to move closer to the wood board until both side contact plates 5 are in contact with and press against the composite bamboo and wood flooring. Because the two side contact plates 5 move the same distance under the action of the adjusting frame 4 and the connecting rod 55, the composite bamboo and wood flooring is pushed to the center position on the connecting frame 2. At the same time, the damper 54 is compressed, and its rebound force applies pressure to the side contact plate 5. This pressure is the side contact plate 5 pressing force on the side of the composite bamboo and wood flooring. Before centering the composite bamboo flooring, the moving frame 81 is moved by the pressure cylinder 8 fixedly installed on the adjusting frame 4, so that the moving frame 81 drives the guide rod 71 to slide along the adjusting frame 4, so that the guide rod 71 drives the pressure frame 7 to move vertically downward. At this time, the contact roller 75 below the pressure frame 7 moves accordingly until the contact roller 75 contacts the composite bamboo flooring. When the contact roller 75 contacts and presses the composite bamboo flooring, the contact roller 75 moves relative to the pressure frame 7, causing the rotating seat 741 to drive the pressure main rod 74 to move. Since the adjusting seat 73 is threadedly connected to the bidirectional lead screw 72 in the pressure frame 7, the position of the adjusting seat 73 is limited when the bidirectional lead screw 72 is not driving, and thus the pressure main rod 74 moves, causing the pressure main rod 74 to rotate along the adjusting seat 73. Under the rotation of the pressure main rod 74, the pressure support rod 76 is pushed to move accordingly, causing the pressure support rod 76 to push the extrusion block 77 to slide on the inner wall of the pressure frame 7. As the extrusion block 77 moves, it compresses the pressure spring 78. When the pressure spring 78 is compressed, it pushes the pressure support rod 76 in the opposite direction. The force is transmitted to the contact roller 75 through the pressure support rod 76 and the pressure main rod 74. A pressure sensor is set between the pressure frame 7 and the pressure spring 78 to detect the pressure of the contact roller 75 on the composite bamboo flooring, determine whether it is in contact with the composite bamboo flooring and extruding it, and control its initial pressure. The pressure sensor is located between the pressure spring 78 and the pressure frame 7, or in the circuit of the pressure cylinder 8, to detect the pressure under the contact roller 75.

[0032] As the contact roller 75 moves downward, the pressure rod 74 rotates, causing the contact roller 75 to move to both sides. This causes the contact roller 75 to apply a pushing force to the top of the composite bamboo flooring from both sides. When cutting, the force applied to the composite bamboo flooring is divided into lateral force and upward force, thereby preventing the composite bamboo flooring from springing up while also applying lateral pressure to avoid applying force to the composite bamboo flooring during cutting and improving its stability during cutting.

[0033] At this time, the side contact plate 5 is controlled by the cylinder 6 to apply pressure to the side of the composite bamboo flooring. The side contact plate 5 pulls the adjusting frame 4 downward through the connecting rod 55, which in turn causes the adjusting frame 4 to drive the pressure frame 7 downward. At this time, the contact roller 75 further applies pressure to the top surface of the composite bamboo flooring, which prevents the composite bamboo flooring from being squeezed and bent when the side contact plate 5 is pressing on both sides. As the side contact plate 5 moves, the downward movement distance of the pressure frame 7 gradually increases, controlling the contact roller 75 to increase the top pressure of the composite bamboo flooring, further preventing the composite bamboo flooring from bending upward. At the same time, the contact roller 75 applies lateral tension to the composite bamboo flooring, further preventing the composite bamboo flooring from bending and deforming upward, avoiding bending of the composite bamboo flooring during the extrusion process, which would affect the cutting dimensions. When the composite bamboo flooring is conveyed through the output roller on the connecting frame 2, it is fed into the main body 1 of the cutting device. The cutting mechanism in the main body 1 of the cutting device cuts the composite bamboo flooring. After the cutting is completed, it is conveyed out from the support platform 12 on the other side of the main body 1 of the cutting device. The debris generated during the cutting process is sucked out from the ventilation port 11 to avoid affecting the processing environment.

[0034] The method of using the pressure cutting device for processing composite bamboo flooring includes the following steps: S1: Place the composite bamboo flooring on the conveyor roller of the connecting frame 2; S2: Start the drive unit to drive the side contact plates 5 on both sides to move towards each other, clamp and push the composite bamboo flooring to the center position. During this process, the side contact plates 5 pull the adjustment frame 4 and the pressure component down synchronously through the connecting rod 55. S3: The contact roller 75 of the pressure component contacts the top surface of the composite bamboo and wood flooring, and increases the downward pressure as the adjusting frame 4 continues to descend. At the same time, the contact roller 75 generates a partial pressure on the floor surface pointing to both sides. S4: Start the conveyor rollers to send the multi-directionally compressed composite bamboo and wood flooring into the main body 1 of the cutting device for cutting.

[0035] In step S2, a push cylinder 6 drives one side contact plate 5, and through the linkage of the connecting rod 55 and the adjusting frame 4, the two side contact plates 5 move towards each other at equal distances and synchronously.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
