Description

Technical Field

[0001] The invention belongs to the technical field of material slitting, and in particular relates to a slitting machine for producing bamboo composite materials. Background Art

[0002] Bamboo composite material is a composite material made of wood and bamboo as the main raw materials, in accordance with the assembly method of wood veneer laminated lumber, and processed with adhesives. During the processing, the bamboo composite material coil to be cut is placed in the specified position of the equipment, and the tension is adjusted to ensure that the material remains stable during the cutting process. The cutting width of the slitting machine is set according to production requirements. This usually involves adjusting the position of the tool or replacing tools of different widths. According to the characteristics of the material and production requirements, the running speed of the slitting machine is set. Ensure that the speed can meet the production efficiency without causing damage to the material.

[0003] For the slitting of strip bamboo composite materials, especially for the slitting of sound insulation boards, the bamboo strips need to be cut into specific shapes to improve their sound insulation effect. Advanced special cutting equipment, such as laser cutting machines with arc cutting function, have more advanced control systems and more flexible cutting path planning capabilities, which can more easily achieve arc cutting, but the cost is too high and is not suitable for small and medium-sized enterprises. The traditional cutting disc cutting process can only achieve vertical cutting, which cannot ensure that the sound insulation board is uneven, thus failing to increase the reflection and absorption of sound in the material, thereby reducing the sound insulation effect; on the other hand, when the traditional slitting machine is used to slitting the sound insulation board of bamboo composite materials, although multiple sets of circular blades can complete the cutting, the traditional device cannot perforate the bamboo composite materials in the production process, so after slitting and winding, the unwinding machine is still needed to unwind the bamboo composite board, and then uniformly perforate the surface of the board. This process undoubtedly increases the workload and production cost.

[0004] For this reason, a kind of bamboo composite material production slitting machine is designed to solve the above problems. Summary of the invention

[0025] A sliding block 24 and a sliding groove 25 with sizes matching each other are also provided at the connection between the positioning plate 18 and the lifting plate 17 .

[0031] Working principle: When the device is in use, the bamboo composite board can be piled up at the feed of the board conveyor 1, and then one end is pulled through the slitting frame 2. After being cut by the hollow slitting slice 3, the cut end surface is pulled to the bottom of the short bracket 28, and passes through the bottom of the guide roller 29. Then it is lifted to the top of the high bracket 30, passes through the guide roller 2 31 and passes through its upper surface. Then the slitting end is fixed on the coiling roller, and multiple groups of equally divided bamboo composite boards are isolated at equal intervals by the isolation sheet 23, and the winding after slitting is completed. During the specific operation, the driving motor 8 on the outside of the slitting frame 2 can be started, and the driving 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 pushing cylinder 11 on the limiting plate 14 is started, and its output end pushes the guide rod 12, and the guide rod 12 flexibly pushes and pulls the hollow slitting slice 3 along the central axis of the hinge seat 13. At this time, the upper and lower groups of pushing cylinders 11 are kept in reverse synchronization. When the pushing cylinder 11 is started, multiple groups of hollow slitting slices 3 complete left and right swings in the middle of the anti-dropping sleeve 10. The outer side of the anti-dropping sleeve 10 is raised to prevent the hollow slice 3 from falling off; and the outermost guide rod 12 can be flexibly extended and retracted in the hollow sleeve rod 32 to cooperate with the streamline 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 with the same thickness on a unified path. By accurately 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 within a specific frequency range. When the board after slicing passes through the perforated bracket 4, the upper power cylinder 15 is started, and the lifting plate 17 is pushed by the push rod 16. The lifting plate 17 cooperates with the slide groove 25 of the positioning plate 18 through the outer slider 24, so that the lifting plate 17 drives the punching needle 19 below to press down steadily, and the punching needle 19 passes through the bamboo board and extends into the pinhole 27, thereby achieving a punching effect, so that small holes are evenly distributed on the material, which can increase the propagation path of sound and make the sound reflected and absorbed multiple times inside the bamboo board. Finally, the DC motor 21 on the mounting plate 20 is started to drive the coiling roller to complete the unified collection of the slit materials.
