Technical Field
After the silkworms grow to be mature, the silkworms need to be provided with tufting tools for spinning and cocooning, and cocoons produced by the silkworms are poor in quality and eliminated by using a grass cage self-made by farmers in the past. Later, plastic cocooning frame is popularized, because the plastic material does not absorb silkworm urine, liquid excrement in the silkworm cocooning process is easy to stick to the silkworm cocoons, although the cocoon quality of the silkworm cocoons formed by the plastic cocooning frame is improved, the plastic cocooning frame is not beneficial to silk reeling. Paper cocooning frames are commonly used at present, and cocooning quality and silk quality of the cocooning frame knots are good. The paper cocooning frame structure comprises a frame body located on the periphery, wherein a plurality of transverse sheets and longitudinal sheets are arranged in the frame body in parallel, and the transverse sheets and the longitudinal sheets are arranged in a crossed mode in a cross shape. When the check cluster is prepared, half openings are respectively cut at corresponding positions of the transverse sheet and the longitudinal sheet, then the openings on the transverse sheet and the longitudinal sheet are spliced together through manual splicing, and then the frame is bonded on the periphery of the transverse sheet and the longitudinal sheet, so that the preparation labor intensity of the check cluster is high. The paper is easy to deform, so that the paper easily falls off and droops at the intersection position of the transverse sheet and the longitudinal sheet when the paper is used for the second time, and the service life of the paper cocooning frame is short. In addition, the silkworm cocoons can be picked only by manual operation and cannot be picked at one time by adopting mechanical whole-piece paper cocooning frames.
At present, on one hand, silkworm breeding personnel are aged, and the key point for promoting labor-saving silkworm breeding is to develop silkworm breeding mechanization, and on the other hand, proper large-scale silkworm breeding is realized by silkworm breeding mechanization. The cocoon picking machine has been developed successfully, and matched cluster tools need to be kept up urgently. At present, a wood square cluster is made, although the strength is enough and the wood square cluster is not deformed, the structural principle of the paper square cluster is still used, half edges of wood chips are cut into gaps, the wood grains are easy to break after being cut, and the service life is short; the wooden paper cocooning frame has high cost and no investment for farmers. Therefore, it is necessary to invent a paper cocooning frame which has high strength, does not deform and is suitable for mechanical cocoon picking.
