Embodiment Construction
[0019] The present invention and its embodiments will be further described below in conjunction with the accompanying drawings.
[0020] A method for preparing a three-dimensional concave-convex pattern plate molded with bamboo and wood shavings, the method comprising the following steps:
[0021] A. Paving: the bamboo and wood shavings blanks are evenly spread on the slab conveyor belt running at a constant speed under the paving machine through a fixed paving machine to form a slab with a thickness of 12-24mm;
[0022] B. Trimming When the slab obtained in step A reaches the set length, the paving machine stops paving; at the same time, the slab conveyor belt stops running, and the vertical edge suction machine and the horizontal edge suction machine cut it;
[0023] C. Pre-pressing——The slab conveyor belt continues to run, and the trimmed slab is sent to the bottom of the flat-pressing pre-pressing machine through the slab conveyor belt, and the slab conveyor belt stops run...

The invention provides a method of preparing bamboo wood shaving crushed aggregate mould pressing stereo ridge design sheet and an equipment combination for realizing the method. The process method comprises the following steps of A material spreading, B edge clipping, C preloading, D delivering and E hot press molding. Equipment for realizing the process method comprises a paving machine, a slab transmission zone, a flat pre-press machine and more than one single opening hot press. A trolley is arranged between front end of the single opening hot press and the slab transmission zone. The fixed multi-head paving machine paves intermittently, and the slab transmission zone synchronously works with the paving machine intermittently. The flat pre-press machine pre-presses intermittently, and a crossbar edge absorbing machine synchronously works intermittently with the pre-press machine. The paving and the pre-pressing are matched with each other intermittently. The technical scheme can effectively solve the process hard problem that the slab fracture easily appears during the continuous pre-pressing of the production of thin crushed aggregate pallet boards. Produced products accord with the relative requirements of the national standard and have the advantages of good quality and high qualified rate. Raw materials are saved, and the cost is lowered.
Description
technical field [0001] The invention relates to a new process for producing molded boards, which belongs to the technical field of chipboard (broken material) processing. Specifically, the present invention relates to a method for preparing a board with three-dimensional concave-convex patterns molded from bamboo and wood shavings and a combination of equipment for realizing the method. Background technique [0002] The existing domestic production of particleboard (particle board) or fiberboard (including fiber molded door skin) slab and board making process has the following three methods: [0003] One is to use the continuous paving method of the fixed paving machine with multiple paving heads. The slab conveyor belt moves continuously, and the formed slabs are pre-pressed by counter-rollers or multi-roller endless belts, and the cross-section is accelerated. The pre-pressed slab is fed into a single-layer or multi-layer hot press and then formed into a sheet; the second...
