Chipping machine for producing oriented strand boards on basis of plant stems

Abstract

The invention provides a chipping machine for producing oriented strand boards on the basis of plant stems. The chipping machine comprises a chipping knife set, a feeding device and a martial blockingdevice. A material push plate set is fixed to the feeding device. The end portions of all material push plates in the material push plate set are connected with the material blocking device in a clamping manner when moving to the portion below the material blocking device along with the feeding device. When materials move to the chipping knife set, a closed area is formed on the periphery of thematerials through the material push plates and the material blocking device, and therefore the materials are limited both in the vertical direction and the feeding direction and cannot move or fall, and it is ensured that the materials can make contact with the chipping knife set. The chipping machine for producing the oriented strand boards on the basis of the plant stems has the beneficial effects of being uniform in produced segment length, high in discharging speed and high in production efficiency.

Description

technical field [0001] The invention relates to processing equipment suitable for woody plant stems and grass plant stems in the field of oriented strand board production, in particular to a chipper for producing oriented strand boards based on plant stems. Background technique [0002] The chipper used in the field of particleboard production is also called wood chipper. It belongs to one of the series of equipment for particleboard pretreatment process. [0003] The existing particleboard pretreatment process first uses a chipper to cut into irregular blocks, and then flakes through a planer. The raw material of the traditional OSB is wood with a larger diameter, and for plant stems with a smaller diameter, if After entering the chipper using the traditional particleboard process, it will become irregular broken bodies, and then it cannot produce sheet materials suitable for making oriented strand boards after entering the chipper. [0004] At present, for chipping equipm...

Problems solved by technology

[0003] The existing particleboard pretreatment process first uses a chipper to cut into irregular blocks, and then flakes through a planer. The raw material of the traditional OSB is wood with a larger diameter, and for plant stems with a smaller diameter, if Using the traditional particleboard process, it will become irregular broken bodies after entering the chipper, and it will not be able to produce flake materials suitable for making oriented strandboard after entering the chipper

[0004] At present, for chipping equipment for irregular materials, the material is fed radially, and the chips are chipped at the discharge port by means of guillotine, rotary cutting or sawing; due to the irregular length and shape of the stems of plants such as straw, the use of When this kind of equipment is chipping, some plant stems may fall from the discharge port before touching the cutter, the chipping effect is poor, and the segment length is uneven; in addition, the output speed of this kind of chipping equipment is relatively slow , which is far from matching the feeding speed, and because the plant stems have a certain degree of toughness, it often causes the chipping equipment to be stuck, which not only shortens the service life of the equipment, but also further slows down the chipping efficiency
