Description

Technical Field

[0001] This invention belongs to the field of material slitting technology, specifically relating to a slitting machine for bamboo composite material production. Background Technology

[0002] Bamboo composite material is a composite material made primarily from wood and bamboo, assembled using a laminated veneer lumber method and bonded together. During processing, the bamboo composite roll to be slit is placed in the designated position on the equipment, and tension is adjusted to ensure the material remains stable during slitting. The slitting width of the slitting machine is set according to production needs. This typically involves adjusting the blade position or replacing blades with different widths. The operating speed of the slitting machine is set based on the material characteristics and production requirements, ensuring that the speed meets production efficiency without damaging the material.

[0003] For the slitting of bamboo composite materials, especially when used in the manufacture of sound insulation boards, bamboo strips need to be cut into specific shapes to improve their sound insulation effect. Advanced specialized cutting equipment, such as laser cutting machines with arc cutting capabilities, has a more advanced control system and more flexible cutting path planning capabilities, making it easier to achieve arc cutting. However, the cost is too high, making it unsuitable for small and medium-sized enterprises. Traditional cutting disc cutting technology can only achieve vertical cutting, which cannot guarantee the texture of the sound insulation board, thus failing to increase the reflection and absorption of sound in the material, thereby reducing the sound insulation effect. On the other hand, when using traditional slitting machines to slit bamboo composite sound insulation boards, although multiple sets of circular blades can complete the cutting, the traditional device cannot perforate the bamboo composite material during the production process. This means that after slitting and winding, an unwinding machine is still needed to unwind the bamboo composite board and then perforate the surface of the board. This process undoubtedly increases the workload and production cost.

[0004] Therefore, a slitting machine for bamboo composite material production is designed to solve the above problems. Summary of the Invention

[0005] To address the problems mentioned in the background section, this invention provides a slitting machine for bamboo composite material production. Traditional cutting disc processes can only achieve vertical cutting, failing to ensure the sound insulation board has a distinct texture, thus failing to increase sound reflection and absorption within the material, thereby reducing the sound insulation effect. Furthermore, while multiple sets of circular blades can complete the cutting process when using traditional slitting machines to cut bamboo composite sound insulation boards, the inability of traditional devices to perforate the bamboo composite material during production necessitates the use of an unwinding machine to unroll the bamboo composite board after slitting and winding, followed by unified perforation of the board surface. This process undoubtedly increases workload and production costs.

The winding assembly is used to wind the slit bamboo board. The hollow slitting slice is used to cut the bamboo board laid flat on the board conveying platform into equal intervals. The streamlined push-pull assembly is used to push the hollow slitting slice back and forth and cut the bamboo board into a streamlined concave-convex structure of uniform thickness.

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.

[0033] like Figure 1-8 The slitting machine for bamboo composite material production shown includes a board conveying table 1, a slitting frame 2, hollow slitting slices 3, a perforation bracket 4, a streamlined push-pull assembly 5, a perforation assembly 6, and a winding assembly 7.

[0034] The streamlined push-pull assembly 5 includes a drive motor 8, a connecting shaft 9, an anti-detachment bushing 10, a push cylinder 11, a guide rod 12, a hinge seat 13, and a limiting plate 14.

[0035] The board conveying table 1, together with the slitting frame 2, is used to support the bamboo composite board and convey it to the winding assembly 7. The winding assembly 7 is used to wind the slit bamboo board. The hollow slitting slice 3 is used to cut the bamboo board laid flat on the board conveying table 1 at equal intervals. The streamlined push-pull assembly 5 is used to push the hollow slitting slice 3 back and forth and cut the bamboo board into a streamlined concave-convex structure of the same thickness.

When the pushing cylinders 11 are activated, the multiple hollow slicing slices 3 swing left and right in the middle of the anti-detachment bushing 10. The guide rods 12 cooperate with the telescopic function of the hollow sleeve rod 32 to complete displacement compensation, so that the porous hollow slicing slices 3 can cut the bamboo composite board into a streamlined concave-convex structure of uniform thickness along a unified path, and improve the sound insulation effect of the bamboo composite board. After slicing, the bamboo board is pierced by multiple sets of perforating needles 19, so that small holes are evenly distributed on the material, which can increase the sound propagation path and make the sound reflect and absorb multiple times inside the bamboo board. The separator 23 can separate the slit bamboo boards into segments. The short support 28 is used to guide the bamboo boards and make holes smoothly. The high support 30 lifts the bamboo boards, so that the bamboo boards are lifted to the upper end of the winding roller and kept in a high position.

The punch 19 is fixedly connected to the bottom surface of the lifting plate 17, and the surface of the punch 19 is slidably connected to the inner wall surface of the plate conveying table 1.

[0038] The winding assembly 7 includes a mounting plate 20, a DC motor 21, a winding shaft 22, and a separator 23. The mounting plate 20 is fixedly connected to the surface of the board conveying table 1. The DC motor 21 is threadedly connected to the inner side of the mounting plate 20. One end of the winding shaft 22 is fixedly connected to the motor shaft of the DC motor 21 through a coupling. The separator 23 is sleeved on the outer side of the winding shaft 22, and one side surface of the separator 23 is slidably connected to the cut of the bamboo composite board.

[0039] The connection between the positioning plate 18 and the lifting plate 17 is also provided with a slider 24 and a groove 25 that are adapted to each other in size.

[0040] The hollow slab 3 has a through hole 26 inside, and the diameter of the through hole 26 is larger than the middle diameter of the anti-detachment bushing 10.

[0041] The inside of the sheet material conveying table 1 near the lifting plate 17 is also provided with a pinhole 27 that matches the size of the punch 19.

[0042] The board conveying table 1 is provided with a short support 28 and a guide roller 29 on both sides of the perforated bracket 4. The short support 28 is fixedly connected to the surface of the board conveying table 1, and the guide roller 29 is rotatably connected to the inner side of the short support 28, and the bottom of the guide roller 29 is in contact with the surface of the bamboo composite board.

[0043] A high support 30 and a guide roller 31 are also provided on the side of the board conveying table 1 near the isolation plate 23. The high support 30 is fixedly connected to the surface of the board conveying table 1, and the guide roller 31 is rotatably connected to the inner side of the high support 30, and the top surface of the guide roller 31 is in contact with the surface of the bamboo composite board.

[0044] A hollow sleeve rod 32 is also fixedly connected to the side of the slitting frame 2 away from the limiting plate 14. The inner wall of the hollow sleeve rod 32 is slidably connected to the surface of the guide rod 12.

[0045] Working principle: When using this device, bamboo composite boards can be piled up at the feeding point of the board conveyor table 1. Then, one end is pulled through the slitting frame 2, cut by the hollow slitting slice 3, and the cut end is pulled to the bottom of the low support 28 and passes through the bottom of the guide roller 29. Then, it is lifted to the top of the high support 30, passes through the guide roller 31 and passes through its upper surface. Then, the slitting end is fixed on the roll roller. Multiple groups of bamboo composite boards that are equally divided are separated by the isolation plate 23 to complete the winding after slitting. In specific operation, the drive motor 8 on the outside of the slitting frame 2 can be started. The drive motor 8 drives the connecting shaft 9 to rotate, and the connecting shaft 9 drives the limiting plate 14 sleeved on the outside to rotate. At the same time, the push cylinder 11 on the limiting plate 14 is started, and its output end pushes the guide rod 12. The guide rod 12 flexibly pushes and pulls the hollow slitting slices 3 along the central axis of the hinge seat 13. At this time, the upper and lower sets of push cylinders 11 are kept in opposite directions and synchronized. When the push cylinder 11 is started, multiple sets of hollow slitting slices 3 complete left and right swings in the middle of the anti-drop bushing 10. The action of the anti-detachment bushing 10 is to raise the outer side to prevent the hollow slice 3 from falling off; while the outermost guide rod 12 can flexibly extend and retract within the hollow sleeve rod 32 to cooperate with the streamlined movement of the hollow slice 3 for displacement compensation, so that the porous hollow slice 3 can cut the bamboo composite board into a streamlined concave-convex structure of the same thickness on a unified path. By precisely designing the shape and distribution of the concave-convex structure, it can be optimized for sound waves of different frequencies, so that the sound insulation board made of bamboo composite board has better sound insulation performance in a specific frequency range. When the board after slicing passes through the perforated bracket 4, the upper power cylinder 15 is activated, and the lifting plate 17 is pushed by the push rod 16. The lifting plate 17 cooperates with the sliding groove 25 of the positioning plate 18 through the outer slider 24, so that the lifting plate 17 drives the lower perforating needle 19 to press down smoothly. The perforating needle 19 passes through the bamboo board and extends into the needle hole 27, thereby achieving the perforation effect, so that small holes are evenly distributed on the material, which can increase the sound propagation path and make the sound reflect and absorb multiple times inside the bamboo board. Finally, the DC motor 21 on the mounting plate 20 is started to drive the roll rollers, thereby completing the unified collection of the slit materials.
