为方便送料，所述静态接料机构14前端设有第一自由辊组3，储料箱7后端依次设有第二自由辊组23、材料稳定箱8和一对牵引辊33。 For the convenience of feeding, the front end of the static receiving mechanism 14 is provided with a first free roller group 3, and the rear end of the storage box 7 is provided with a second free roller group 23, a material stabilization box 8 and a pair of traction rollers 33 in sequence.
材料稳定箱8上设有与抽风装置相连的排风口8-1，且材料稳定箱8的与物料接触的端面上分布有吸气口8-2。 The material stabilizing box 8 is provided with an air exhaust port 8-1 connected with the draft device, and an air suction port 8-2 is distributed on the end surface of the material stabilizing box 8 which is in contact with the material.
使用时，材料稳定箱8始终吸附于设有所述吸气口8-2的端面上，同时采用一对牵引辊33进行牵引，可确保在第二自由辊组23至自由辊组3之间的物料始终具有一定张力，防止物料发生叠合等情况，进而确保了供料的稳定性。 During use, the material stabilizing box 8 is always adsorbed on the end face provided with the suction port 8-2, and a pair of traction rollers 33 are used for traction at the same time, which can ensure that there is a gap between the second free roller group 23 and the free roller group 3. The materials always have a certain tension to prevent the materials from overlapping and so on, thus ensuring the stability of the feeding.
