Shaving board manufacturing raw material pretreatment process

Abstract

The invention relates to a shaving board manufacturing raw material pretreatment process. Equipment included in the shaving board manufacturing raw material pretreatment process comprises supporting legs, an upper table top, an external driving device, an outer stirring ring, a vibration agitation base and a chopping device, wherein the upper table top is fixedly mounted at the top ends of the supporting legs. According to the shaving board manufacturing raw material pretreatment process, inner stirring blocks are fixedly arranged in the outer stirring ring at intervals, each inner stirring block is provided with an inclined surface structure, the inclined surfaces between every two adjacent inner stirring blocks are in a shape of a tip which is concave inwards in the rotating direction, and the whole outer stirring ring can be driven by the external driving device to rotate, so that the stirring effect of internal raw materials is guaranteed, the situation that a cutter only crushes raw materials on the layer where the cutter is located is avoided, meanwhile, the stirring effect of the raw materials can be further improved through overall rotation of the outer stirring ring, and moreover, the cutter is further provided with a flapping plate capable of flapping for flapping and mixing the raw materials, so that the crushing uniformity is improved.

Description

technical field [0001] The invention relates to the technical field of particleboard production, in particular to a pretreatment process for particleboard manufacturing raw materials. Background technique [0002] Particleboard is also called particle board, which cuts various branches, small-diameter wood, fast-growing wood, sawdust, etc. A kind of wood-based panel, the particles are arranged unevenly, and the wood chips, shavings, wood wool, sawdust, etc. processed into flakes, strips, needles, and granules are called scraps, and these scraps are produced through The original larger raw materials are obtained by crushing. For example, the shavings and scraps are all long and wide shavings produced by the previous equipment after being crushed to form shavings and scraps. There are some problems: [0003] For the crushing of raw materials, the existing equipment puts the raw materials directly into a large rotary crushing equipment, and the blades that are simply set insi...

Problems solved by technology

[0003] For the crushing of raw materials, the existing equipment puts the raw materials directly into a large rotary crushing equipment, and the blades that are simply set inside are driven by the motor to rotate and crush. Simply rotate the chopping blade, and the inside of the equipment is filled to process a large amount of raw materials at one time, so it is difficult for the internal raw materials to be evenly mixed and rotated under the rotation of the chopping blade, which will cause the chopping blade to always be where the cutting blade is The raw material of the layer, and for the layer without the blade, it cannot be broken well no matter how long it is rotated, because it cannot be in good contact with the blade, thereby reducing the crushing effect of the raw material, and if the blade is used for stirring while chopping, It will also greatly reduce the cutting efficiency of the blade. On the other hand, most of the existing equipment uses a large amount of raw materials as a whole to be crushed for a period of time, and then check the crushing situation before deciding whether to continue crushing or take out the crushed materials for later use. This method is not only inconvenient to improve work efficiency, but also cannot accurately control the crushing degree of the collected scraps. The overall chopping effect can only be evaluated based on the crushing effect of a large number of raw materials, and it is impossible to collect every point. Control of the crushing effect of the crushed material
