[0002] The tensile heat setting machine used in the processing of polyester staple fibers is a key equipment. It is mainly used to perform heat setting treatment on polyester staple fibers to improve the shape stability and physical and mechanical properties of the fibers. The tensile heat setting machine usually uses steam or heat-conducting oil as the heating medium to heat the hot roller. During the heat setting process, the polyester staple fibers are heated and stretched by the hot roller, so that the fiber molecular segments are rearranged and the internal stress is eliminated, thereby improving the dimensional stability and shape stability of the fibers.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides a technical solution:

[0027] See also Figures 1 to 4 A tensile heat setting machine for polyester staple fiber processing comprises a device frame 1, four heating rollers 2 are arranged inside the device frame 1, and adjustment mechanisms for processing polyester with different elasticity are arranged above the four heating rollers 2, a liquid storage tank 5 is arranged on the side wall of the device frame 1, and a conveying mechanism for conveying heating liquid is installed inside the liquid storage tank 5;

[0028] The adjusting mechanism includes an auxiliary roller 3, and four auxiliary rollers 3 are provided. The four auxiliary rollers 3 are respectively arranged above the heating roller 2. One end of the four auxiliary rollers 3 is rotatably connected to an adjusting plate 31 through a bearing. Two guide rods 32 fixed to the device frame 1 are penetrated inside the adjusting plate 31. Two adjusting screws 33 are threadedly connected to the inner wall of the adjusting plate 31. Electric heating wires 34 are installed inside the four auxiliary rollers 3. A protective door 4 is hinged on the outer wall of the device frame 1. A liquid filling port 6 is opened on the upper surface of the liquid storage tank 5. The conveying mechanism includes a conveying pump 7. The conveying pump 7 is fixed to the inside of the liquid storage tank 5 by bolts. The output end of the conveying pump 7 is connected to a conveying pipe 71. The end of the conveying pipe 71 is connected to a connecting piece 72. A fixed bearing 73 is fixed to the inner wall of the connecting piece 72.

[0029] By adopting the above technical scheme, before using the tension heat setting machine for polyester staple fiber processing, the device frame 1 is first placed in a suitable position, the polyester staple fiber to be processed is bypassed around the outer surfaces of the heating roller 2 and the auxiliary roller 3 respectively, and then the polyester staple fiber is connected to the external winding device, and then the protective door 4 is closed to play a protective role. The winding device winds the polyester staple fiber, and the heating oil is conveniently added through the liquid filling port 6 provided on the liquid storage tank 5. At this time, the delivery pump 7 in the liquid storage tank 5 is started to pump the oil out and send it to the delivery pipe 71. A heating device is provided between the delivery pipe 71 and the delivery pump 7, which can assist in heating the oil. By twisting the adjusting screw 33, with the cooperation of the guide rod 32, the adjusting screw 33 is rotated to drive the threaded adjustment plate 31 to move vertically, and then the distance between the auxiliary roller 3 and the heating roller 2 is adjusted, which is convenient for regulating and shaping polyester staple fibers with different elasticities. The provided electric heating wire 34 can heat the auxiliary roller 3 to assist in heat setting and improve practicality.

[0030] Specifically, Figure 1-Figure 4 As shown, a connecting rod 74 is fixed to the inner wall of the fixed bearing 73, and a through hole 75 which is interconnected with the connecting piece 72 is formed on the outer surface of the connecting rod 74. A flow cavity 76 which is interconnected with the connecting rod 74 is formed inside the four heating rollers 2, and one end of the four heating rollers 2 is connected to a connecting pipe 77 which is interconnected with the flow cavity 76, and the end of one heating roller 2 is connected to a reflux pipe 8 which is interconnected with the liquid storage tank 5.

[0031] By adopting the above technical solution, the oil flows into the interior of the connecting piece 72. Since the surface of the connecting rod 74 has a through hole 75, the oil can enter the interior of the connecting rod 74 through the through hole 75, and then flow into the flow cavity 76 to heat the heating roller 2. The polyester staple fiber is heated when passing through the outer surface of the heating roller 2, thereby shaping the polyester staple fiber. When the polyester staple fiber is being transported, the heating roller 2 will be driven to rotate under the action of friction. The rotation of the heating roller 2 drives the connecting rod 74 to rotate. With the cooperation of the fixed bearing 73, the connecting piece 72 will not be driven to rotate, thereby ensuring the normal operation of the shaping machine. Through the connecting piece 72 set at the other end of the heating roller 2, with the cooperation of the connecting pipe 77, the oil can flow into the other heating roller 2, thereby improving the heating and shaping effect of the polyester staple fiber. Through the reflux pipe 8, the oil that continuously flows into the heating roller 2 can enter the liquid storage tank 5 again for circulation.

[0032] Working principle: The polyester staple fibers to be processed are passed around the outer surfaces of the heating roller 2 and the auxiliary roller 3 respectively, the protective door 4 is closed, and the delivery pump 7 in the liquid storage tank 5 is started, and the oil is pumped out and sent to the delivery pipe 71, and flows into the inside of the connecting piece 72. Since the surface of the connecting rod 74 has a through hole 75, the oil can pass through the through hole 75 into the inside of the connecting rod 74, and then flow into the flow cavity 76 to heat the heating roller 2. The polyester staple fibers are heated when passing through the outer surface of the heating roller 2, and then the polyester staple fibers are shaped. When the polyester staple fibers are transported, the heating roller 2 will be driven to rotate under the action of friction, and the rotation of the heating roller 2 drives the connecting rod 74 Rotation, with the cooperation of the fixed bearing 73, will not drive the connecting piece 72 to rotate, thereby ensuring the normal operation of the shaping machine; through the connecting piece 72 set at the other end of the heating roller 2, with the cooperation of the connecting pipe 77, the oil can flow into the other heating roller 2, thereby improving the heating and shaping effect of the polyester staple fiber; by twisting the adjusting screw 33, with the cooperation of the guide rod 32, the adjusting screw 33 is rotated to drive the threaded adjustment plate 31 to move vertically, thereby adjusting the distance between the auxiliary roller 3 and the heating roller 2, so as to facilitate the regulation and shaping of polyester staple fibers with different elasticities; the arranged heating wire 34 can heat the auxiliary roller 3.
