Description

Technical Field

[0001] This utility model relates to the field of short fiber manufacturing technology, and in particular to a crimping mechanism for PET hollow short fibers. Background Technology

[0002] The crimping mechanism for PET hollow staple fibers is a key piece of equipment in the fiber processing. Its core function is to crimp the fibers through mechanical or thermal action, thereby improving the fiber's cohesion, elasticity, and bulkiness to meet the performance requirements of textiles, filling materials, and other fields. The crimping of PET hollow staple fibers is mainly achieved through a crimping box type crimping machine. Preheated fibers are fed into the crimping box, which contains a movable plate and a fixed blade. Inside the box, the fibers are compressed and packed, simultaneously subjected to the thrust of the crimping rollers and the resistance of the movable plate, forcing the fibers to bend and deform.

[0003] The conventional PET hollow short fiber crimping mechanism has the following drawbacks: 1. It is not convenient to continuously and uniformly feed the short fibers into the main body of the crimping box, and it cannot achieve uniform preheating to improve its plasticity and crimpability. Therefore, those skilled in the art have provided a PET hollow short fiber crimping mechanism to solve the problems mentioned in the background art. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] The PET hollow short fiber crimping mechanism includes a stuffing box type crimping machine body, a rectangular feed port, and a heat exchange shell;

[0007] A rectangular feeding port is provided at one end of the top of the main body of the packing box type crimping machine. A servo motor is mounted on one end of the rectangular feeding port via a mounting base, and the output shaft of the servo motor is connected to a feeding roller via screws. Feeding plates are installed at equal intervals around the periphery of the feeding roller via screws. A heat exchange sleeve is mounted on the top of the main body of the packing box type crimping machine at one end of the rectangular feeding port via a mounting bracket and bolts. A serpentine heat exchange copper tube is fitted inside the heat exchange sleeve. An electric heating ceramic is installed on one side of the heat exchange sleeve via a mounting hole, and a temperature controller is installed on one end of the electric heating ceramic via screws. A small blower is mounted on the top of the heat exchange sleeve via a mounting base. The bottom outlet of the serpentine heat exchange copper tube passes through the heat exchange sleeve and connects to a hot air delivery pipe, and the other end of the hot air delivery pipe is connected to the bottom end of the rectangular feeding port.

[0008] As a further embodiment of this utility model: the heating end of the electric heating ceramic and the detection end of the temperature controller are both located inside the heat exchange shell. The output end of the temperature controller and the input end of the electric heating ceramic are electrically connected through a wire. The temperature controller automatically controls the electric heating ceramic to heat the heat exchange shell at a constant temperature, thereby increasing the temperature of the serpentine heat exchange copper tube.

[0009] As a further embodiment of this utility model: a servo motor controller is mounted on one end of the servo motor by screws, and the output end of the servo motor controller is electrically connected to the input end of the servo motor by wires.

[0010] As a further improvement of this utility model, a fiber feeding hopper is provided at the top of the rectangular feeding port by means of bolts.

[0011] As a further improvement of this utility model: the output port of the small blower is connected to the input port of the serpentine heat exchange copper pipe through the air inlet pipe.

[0012] As a further improvement of this utility model: a control valve is provided on the hot air conveying pipe, and a discharge port is provided at one end of the main body of the filling box crimping machine. Opening the control valve facilitates the conveying of hot air in the serpentine heat exchange copper pipe to the rectangular discharge port, and the discharge port facilitates the output of processed fibers for use.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Add PET hollow short fibers into the fiber feeding hopper, and use a servo motor to drive the material feeding plate on the outside of the feeding roller to rotate, so as to continuously and evenly feed the short fibers in the fiber feeding hopper into the main body of the filling box crimping machine.

[0015] 2. The electric heating ceramic is automatically controlled by a thermostat to maintain a constant temperature inside the heat exchange jacket, thereby increasing the temperature of the serpentine heat exchange copper tube. Then, a small blower blows outside air into the serpentine heat exchange copper tube to achieve heat exchange. The heated gas is then transported to the bottom of the rectangular discharge port through a hot air conveying pipe, which facilitates uniform heating of the short fibers during transport and improves their plasticity and crimpability.
