The crimping machine is a key device on a short fiber production line, and the crimping effect of the crimping machine directly influences the quality of tows. In staple fiber production lines, the primary purpose of the crimping process is to increase the cohesion and spinnability of the fibers. At present, most of fiber is curled in a filling box type, the curling principle is that a tow with a certain thickness is fed into a curling head, the tow is held by a curling roller and pushed into a filling box, the pushing force of the tow sent into the filling box by an upper curling roller comes from a lower curling roller and props against the pressure of the upper curling roller, an upper plate of the filling box extrudes the tow to generate a retarding force in the filling box, the retarding force enables the tow to form a plug in the filling box, and the tow which is continuously input and the plug are reversely wrinkled and mutually extruded to generate the curling. In order to obtain the best crimping performance, the main pressure of the crimping roller and the back pressure of the crimping box can be adjusted to enable the tows to be uniformly crimped, and the quality requirements of the tows are met.
In recent years, the chemical fiber industry is rapidly developed, and various test production devices in the field of special fibers are produced at the same time. The production of specialty fibers is limited by the insufficient process conditions for the specialty fibers. In a short fiber post-treatment production device, a crimping machine is an indispensable unit machine, the working state of the crimping machine is in great relation with the performance of fibers, the crimping machine is generally designed and improved into a short fiber crimping machine special for various special fibers by relying on the original technology of a polyester short fiber crimping machine, but the glass transition temperature of polyester is 67-81 ℃, the polyester short fiber is a low glass transition temperature fiber, the process control is different from that of a high glass transition temperature special fiber (such as aramid fiber 370 ℃) during crimping, and the high glass transition temperature special fiber short fiber production line modified by a traditional polyester short fiber winding machine has the problems of non-uniform crimping, poor crimping degree, poor crimping fastness and the like.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a be applicable to high glass transition temperature short-staple crimping machine to solve the high glass transition temperature special fiber short-staple production line that traditional polyester staple fiber coiling machine was reformed transform and have the inhomogeneous, the degree of crimpling of curling poor, the poor scheduling problem of curling fastness of curling. Thereby leading the filament bundle to obtain uniform crimping, improving the crimping fastness and improving the cohesive force and spinnability of the fiber.
For realizing above-mentioned technological effect, the application discloses a be applicable to high glass transition temperature short-staple crimping machine, including setting up in last curling roller and the last curling sword and the lower curling sword at curling roller rear portion down, go up the curling sword and form the chamber of curling that holds the short-staple down between the curling sword, go up the curling sword and curl the inside steam delivery passageway that is equipped with of sword down, still be equipped with a plurality of gas pocket UNICOMs of curling sword and the inside steam delivery passageway of curling sword down and the chamber of curling down.
Further, the air holes are arranged in at least one row, and the diameter of each air hole is 0.5-0.8 mm.
Further wherein the vapor delivery passage is wedge-shaped in cross-section.
Further, wherein the lower crimping tool is fixed by a side connecting bolt.
Further, the steam delivery channel is communicated with the steam source through a steam pipeline.
Further, wherein the upper crimping cutter is fixed by an upper connecting bolt.
The beneficial effects of the utility model reside in that:
the crimping box comprises an upper crimping roller, a lower crimping roller, an upper crimping knife and a lower crimping knife which are arranged at an upper interval and a lower interval, wherein the upper crimping roller and the lower crimping knife respectively contain a gas conveying channel, air holes are uniformly distributed on the side close to a crimping cavity and used for conveying high-pressure drying steam so as to improve the temperature of fibers in crimping, and fiber tows are crimped when the temperature is close to the glass transition temperature, so that the fiber tows are uniformly crimped, the crimping fastness is improved, and the cohesive force and the spinnability of the fibers are improved. Tiny air holes are uniformly distributed on the inner side of the crimping cutter, the diameter of each air hole is controlled to be 0.5-0.8mm, and the situation that the air holes are blocked by fibers due to crimping pressure is avoided. The curling knife comprises a high-pressure drying steam conveying channel, and the conveying channel is of a wedge-shaped structure, so that the structural strength of the steam conveying channel is ensured.
