Node diaphragm scraping and sorting device for bamboo split

A node diaphragm scraping and sorting device comprising a scraping device, a sorting device, and a clamping and conveying device arranged between the scraping device and the sorting device, or in front of the sorting device;

• the scraping device and the sorting device are arranged from front to back along an axis;
• the scraping device comprises a conical cylinder with rear part and a front part, the rear part is smaller than the front part, at least two pressing semi-rings are arranged in a circumferential direction of the conical cylinder and are connected to a pressing power device which drives the pressing semi-rings to move in a radial direction of the conical cylinder, and a scraping ring is arranged on a periphery of the front part of the conical cylinder;
• the pressing semi-rings, under the driving of the pressing power device, are configured to press the bamboo split, which passes through a position between the conical cylinder and the pressing semi-rings, on the scraping ring;
• the sorting device comprises a sleeve and two shifting forks located at ends of the sleeve;
• the sleeve is e-shaped and is provided with an inner cylinder and an outer cylinder to form a double-layer structure;
• a clearance t between the inner cylinder and the outer cylinder satisfies:
• h<t<2h, and h is a thickness of the bamboo split;
• the shifting forks each comprise a plurality of shifting rods extending in a radial direction of the sleeve;
• the shifting forks are configured to be driven to rotate around the axis;
• and a transverse outlet is formed between a side edge of the inner cylinder and a side edge of the outer cylinder which are at a distance from the axis;
• after the bamboo split penetrates through the clearance between the inner cylinder and the outer cylinder in an axial direction, both ends of the bamboo split are located between two adjacent shifting rods of the shifting forks, the shifting forks are rotated to push the bamboo split to move towards the transverse outlet along the clearance in the circumferential direction of the sleeve and to come out from the transverse outlet, and the relative position of the bamboo split is kept unchanged to ensure the implementation of sorting;
• the clamping and conveying device is configured to clamp the bamboo split in a radial direction and convey the bamboo split in an axial direction;
• the clamping and conveying device comprises an inner ring moving on the axis;
• at least two clamping pressing rings are arranged in a circumferential direction of the inner ring and are connected to a clamping power device which drives the clamping pressing rings to move in a radial direction of the inner ring, and the clamping power device is connected to a conveying power device which drives the clamping power device to move in the axial direction;
• the clamping pressing rings, under the driving of the clamping power device, are able to clamp the bamboo split on the inner ring, and the conveying power device is configured to drive the clamping power device and to cause the clamped bamboo split and the inner ring to move in the axial direction.
