Description

Technical Field

[0001] This utility model relates to the technical field of bamboo board processing equipment, and in particular to an integrated machine for cutting, removing yellowing, and flattening bamboo boards. Background Technology

[0002] Bamboo boards, as a new type of all-natural and environmentally friendly material, have a wide range of applications. Due to their high hardness, wear resistance, and mildew resistance, bamboo boards are now widely used in furniture manufacturing, furniture decoration, handicrafts, and building materials. However, current bamboo processing methods have several shortcomings. First, the equipment used for cutting, removing yellowing, and flattening bamboo is not integrated into a single system. This means that different equipment is needed for different processing operations, increasing complexity and requiring time for transfer and connection between different devices, significantly reducing production efficiency. Second, bamboo is usually processed manually using simple equipment, which is only suitable for small-scale manual production and cannot be used for large-scale mass production. Furthermore, it is time-consuming, labor-intensive, and increases production costs. Utility Model Content

[0003] In view of the problems of existing bamboo board processing equipment, which lacks integrated design and relies on manual operation, resulting in complicated, time-consuming, and labor-intensive processing and significantly reduced production efficiency, this utility model provides an integrated machine for cutting, removing yellowing, and flattening bamboo boards.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A bamboo board cutting, yellowing removal, and flattening integrated machine includes a support frame, a cutting component, a yellowing removal component, and a flattening component. The cutting, yellowing removal, and flattening components are located on top of the support frame. The cutting component includes a saw blade and a conveying mechanism. The saw blade is positioned above the conveying mechanism and moves relative to the conveying mechanism under the drive of a first lead screw mechanism. The yellowing removal component includes several yellowing removal rollers and friction wheels arranged vertically opposite each other. The upper yellowing removal rollers and friction wheels are equipped with a tensioning mechanism. The flattening component includes an upper pressing plate and a lower pressing plate. The upper pressing plate moves relative to the lower pressing plate via several second lead screw mechanisms and several third lead screw mechanisms. Heating wires are provided inside both the upper and lower pressing plates.

[0006] Furthermore, the shearing assembly also includes a gantry frame, a pressure plate, a support plate, a first motor, a length sensor, and a controller. The first lead screw mechanism, pressure plate, saw blade, support plate, and first motor are mounted on the gantry frame. The conveying mechanism includes a conveyor belt, rollers, and a second motor. The conveyor belt is located below the gantry frame, and the second motor drives the conveyor belt to move via the rollers. The controller is connected to the length sensor, the first lead screw mechanism, and the second motor.

[0007] Furthermore, the first lead screw mechanism includes two vertically arranged first screws, a first nut disposed on each of the first screws, and a third motor. The ends of the pressure plate are all fixedly connected to the first nuts. The third motor is disposed at the ends of the first screws and connected to the controller. The saw blade, the first motor, and the top of the pressure plate are fixedly connected. The pressure plate has a first slot, and the saw blade is adapted to protrude from the first slot and rotates under the drive of the first motor.

[0008] Furthermore, a first spring is sleeved on the second lead screw, and the first spring is located between the first nut and the gantry frame.

[0009] Furthermore, the cross-section of the material support plate is approximately trapezoidal, and the top has a second slot adapted to the saw blade.

[0010] Furthermore, the yellowing removal assembly includes four sets of yellowing removal rollers, namely the first set, the second set, the third set, and the fourth set. The first set and the fourth set each have two yellowing removal rollers. In the second set, the upper side is the friction wheel and the lower side is the yellowing removal roller. In the third set, the upper side is the yellowing removal roller and the lower side is the friction wheel.

[0011] Furthermore, each of the friction wheels includes a housing, a first friction wheel, and a second friction wheel. The first friction wheel and the second friction wheel are disposed inside the housing and rotate in the opposite direction to the yellowing removal roller under the action of the fourth motor.

[0012] Furthermore, the tensioning mechanism includes a tensioning frame, a slider, a slide rod, and a second spring. The inner wall of the tensioning frame is provided with sliding grooves on both sides, and the slide rod is fixed in the middle. The slider is disposed in the tensioning frame and moves up and down along the sliding grooves and the slide rod. The second spring is sleeved on the slide rod.

[0013] Furthermore, the flattening assembly also includes a lower moving frame and an upper moving frame. The lower pressing plate is disposed in the lower moving frame, and the upper moving frame is connected to the lower moving frame through a plurality of second lead screw mechanisms.

[0015] The beneficial effects of this utility model are as follows: This utility model integrates the shearing component, the yellowing removal component, and the flattening component into a single structure, enabling sequential fixed-length shearing, double-sided yellowing removal, and high-temperature pressure flattening of bamboo boards. Furthermore, the controller enables automated operation, avoiding the problem of reduced production efficiency caused by manual operation. In this utility model, the upper and lower extrusion plates utilize a non-marking flattening and continuous pressure flattening method to produce bamboo boards. This allows the bamboo boards to be fed along the tangential direction of the arc while being flattened under pressure, achieving continuous bamboo board production and significantly improving production efficiency while ensuring product quality.

Detailed Implementation

[0021] This utility model discloses an integrated machine for cutting, removing yellowing, and flattening bamboo boards. The following describes one embodiment of this utility model in detail with reference to the accompanying drawings.

[0022] Combination Figure 1 and Figure 2 As shown, a bamboo board shearing, yellowing removal, and flattening integrated machine includes a support frame 1, a shearing assembly, a yellowing removal assembly, and a flattening assembly, all mounted on top of the support frame 1.

The first lead screw mechanism includes two vertically arranged first screws 6, a first nut disposed on each of the first screws 6, and a third motor 5. The third motor 5 is located at the end of the first screws 6 and fixed to the top of the gantry frame 4. The controller is connected to the third motor 5. Both ends of the pressure plate 8 are fixedly connected to the first nuts. The saw blade 7 and the second motor 2 are fixedly connected to the top of the pressure plate 8. The pressure plate 8 has a first slot, and the lower part of the saw blade 7 is adapted to fit into the first slot and protrudes from the first slot.

The cross-section of the material support plate 9 is approximately trapezoidal, and the top has a second slot adapted to fit the saw blade 7.

[0023] Combination Figure 3 and Figure 4As shown, the yellowing removal assembly includes several yellowing removal rollers 10 and several friction wheels 14. The yellowing removal rollers 10 and friction wheels 14 form four groups of yellowing removal wheels, namely the first group, the second group, the third group, and the fourth group, arranged sequentially. The first and fourth groups each have a pair of yellowing removal rollers 10 arranged vertically opposite each other. In the second group, the upper side is the friction wheel 14, and the lower side is the yellowing removal roller 10; in the third group, the upper side is the yellowing removal roller 10, and the lower side is the friction wheel 14. In the first and fourth groups, the upper yellowing removal rollers 10 are connected to the support 1 via a tensioning mechanism; in the second group, the upper friction wheels 14 are connected to the support 1 via a tensioning mechanism; and in the third group, the upper yellowing removal rollers 10 are connected to the support 1 via a tensioning mechanism. Each friction wheel 14 includes a housing, a first friction wheel, and a second friction wheel. The first and second friction wheels are disposed inside the housing and rotate in the opposite direction to the rotation of the yellowing removal roller 10 under the action of the fourth motor. Each tensioning mechanism includes a tensioning frame 11, a slider 13, a sliding rod 12, and a second spring. Sliding grooves are provided on both sides of the inner wall of the tensioning frame 11. The sliding rod 12 is vertically fixed at the middle position inside the tensioning frame 11. The upper outer wall of the sliding rod 12 has threads and is threadedly connected to the upper part of the tensioning frame 11. The sliding rod 12 passes through the slider 13, and a second spring is sleeved on the sliding rod 12, located between the slider 13 and the tensioning frame 11.

[0024] The flattening assembly includes a lower extrusion plate 17, an upper extrusion plate 18, a lower moving frame 15, and an upper moving frame 16. The lower extrusion plate 17 is disposed within the lower moving frame 15. The upper moving frame 16 is connected to the lower moving frame 15 via four second lead screw mechanisms, each located near a corner of the upper and lower moving frames 15. Each second lead screw mechanism includes a fifth motor 19, a second screw 20, and a second nut. The fifth motor 19 is fixed to the outer wall of the upper moving frame and is driven by the second screw 20. The second nut is fixed to the outer wall of the lower moving frame 15, and the second screw 20 is vertically disposed within the second nut. Under the action of the fifth motor 19, the upper moving frame 16 and the lower moving frame 15 move vertically relative to each other through the cooperation of the second screw 20 and the second nut. The upper extrusion plate 18 is disposed within the upper moving frame 16 and is connected to the upper moving frame 16 via two third lead screw mechanisms. The third lead screw structure includes a sixth motor 21, a third screw 22, and a third nut. The sixth motor 21 is fixedly connected to the upper moving frame 16 and is drivenly connected to the third screw 22. The third nut is fixed on the upper extrusion plate 18. The third screw 22 is arranged laterally inside the third nut. Under the action of the sixth motor 21, the upper extrusion plate 18 moves left and right relative to each other along the upper moving frame 16 through the cooperation of the third screw 22 and the third nut.

[0025] Workers pre-process the bamboo to form several bamboo boards. Each bamboo board passes through a shearing assembly, a yellowing removal assembly, and a flattening assembly in sequence. The bamboo boards are placed on conveyor belt 3, and the second motor 2 drives the conveyor rollers to rotate, thereby moving each bamboo board towards the gantry frame 4. The cross-section of the support plate 9 is approximately trapezoidal, with both sides inclined, which facilitates the bamboo board sliding along the inclined surface of the support plate 9 under the action of the conveyor belt 3 and into the top of the support plate 9. The pressure plate 8 cooperates with the support plate 9 to fix the bamboo board and ensure the normal operation of the saw blade 7. The controller has a preset cutting length for the bamboo board. The controller detects the length of the bamboo board through a length sensor. When the length of the bamboo board reaches the preset cutting length, the controller controls the second motor 2 to stop rotating, thereby stopping the conveyor belt 3 and the bamboo board. Then, the controller controls the first motor 23 and the third motor 5 to start. The first motor 23 drives the saw blade 7 to rotate, and the third motor 5 drives the first screw 6 to rotate, thereby moving the pressure plate 8 and the saw blade 7 gradually downward. The saw blade 7 protrudes from the pressure plate 8 and engages with the second groove of the support plate 9 to smoothly cut the bamboo board according to the cutting length. After cutting, the first lead screw drives the pressure plate 8 and saw blade 7 to reset, and the second motor 2 starts to drive the cut bamboo board to continue moving. In the de-yellowing assembly, the operator can rotate the slide rod 12 to move the de-yellowing roller 10 and friction wheel 14 located on the upper side, which is used to adjust the distance between the de-yellowing roller 10 and between the de-yellowing roller 10 and the friction wheel 14 in the vertical direction. This distance depends on the thickness and mechanical properties of the selected bamboo material. The distance between the upper and lower wheels is adjusted by the tensioning mechanism to better clamp bamboo boards of different thicknesses, moisture contents, and fiber materials, thereby improving the applicability of the bamboo boards. The de-yellowing assembly has a seventh motor, which drives each de-yellowing roller 10 to rotate through a belt and pulley. In the first group, the de-yellowing rollers 10, arranged vertically opposite each other, are used to clamp the bamboo board and convey it inward. The surfaces of the de-yellowing rollers 10 and the friction wheels 14 have several grooves. The friction wheels 14 remove the yellowing and greening from the bamboo board by rotating in the opposite direction to the de-yellowing rollers 10. In the second and third groups, the friction wheels 14 are used to achieve the effect of double-sided de-yellowing and de-greening, ensuring that the surface of the bamboo board is smooth.

[0026] The controller is connected to the heating wire, the fourth motor, and the fifth motor 19. In the fourth group, the upper and lower opposing de-yellowing rollers 10 transport the bamboo board between the upper pressing plate 18 and the lower pressing plate 17. Heating wires are installed inside the upper and lower pressing plates 18 and 17, heating the bottom surface of the upper pressing plate 18 and the top surface of the lower pressing plate 17. The upper pressing plate 18 is connected to the upper moving frame 16 via a third screw mechanism. The fifth motor 19 drives the third screw 22 to rotate. The third screw 22, in conjunction with the third nut, moves the upper pressing plate 18 back and forth along the upper moving frame 16 to adjust it to a suitable position, ensuring more even heating and pressure. Then, the fourth motor drives the second screw 20 to rotate. The second screw 20, in conjunction with the second nut, moves the upper moving frame 16 and the upper pressing plate 18 downwards, pressing the bamboo board under the support of the lower pressing plate 17, thus flattening the bamboo board.

[0027] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
