The existing wool spraying machine or the existing fluff machine has two problems in the use process. The first problem is: the roving breaks up into low-density single fiber fluff and is sprayed into the bundling device, and a small part of the fluff inevitably passes through the through holes on the side wall of the bundling device and floats in the air, so that other devices of the fluff spraying machine are influenced, and even serious safety accidents such as fire disaster and the like can be caused. In addition, since the binder is a cylindrical structure, as shown in fig. 6, the core wire passes through the binder and is not tightly attached to the inner wall of the binder, resulting in poor binding effect. The second problem is: the hollow spindle structure is used for fixing the pressing wire on the fiber bundle, specifically, the driving device drives the pressing wire pipe to rotate, and the pressing wire on the pressing wire pipe can be wound on the fiber bundle, namely twisting, but is limited by mechanical parts of the driving device, compared with the limitation of motor power, the highest rotating speed of a bearing and the like, the rotating speed of the pressing wire pipe cannot be infinitely increased, so that the yarn with larger twisting degree is required to be produced, and the larger twisting degree is realized by reducing the winding speed of the winding structure at the bottom of the velvet spraying machine, so that the production efficiency of the velvet spraying machine is greatly reduced.
