It is a fiber-forming high polymer - polyethylene terephthalate prepared from purified terephthalic acid or dimethyl terephthalate and ethylene glycol through esterification or transesterification and polycondensation reactions, and is made into fibers through spinning and post-treatment. During the processing of polyester, texturing operations are required.
[0003] The existing texturing devices use polyester as the main line and perform texturing by winding low-elasticity filaments around the outer circle of polyester. Different distances between the wire holes for transmitting low-elasticity filaments and the polyester filaments will result in different numbers of winding turns, thereby causing different elasticities of the textured polyester filaments. However, the positions of the wire holes are fixedly opened, which limits the types of polyester filaments that the multifilament texturing device can produce. Different multifilament texturing devices are required for polyester filaments with different elasticities, thus increasing the equipment cost for the production and processing of polyester filaments.
[0004] In summary, the utility model provides a multifilament texturing device to solve the above problems. Content of the Utility Model

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0023] See also Figures 1-4 The utility model provides a technical solution: a multifilament elasticizing device, including a base 1 and an electric rotary drum 3, the top of the base 1 is fixedly connected with a load-bearing frame 2, the electric rotary drum 3 penetrates between the front and back of the load-bearing frame 2, a turntable 4 is penetrated between the back of the electric rotary drum 3 and the back of the inner wall, a fixed cylinder 5 is penetrated through the front of the electric rotary drum 3, the back of the fixed cylinder 5 penetrates through the front of the turntable 4 and extends to the inside of the turntable 4, the outer cylinder surface of the fixed cylinder 5 and located on the front of the turntable 4 are uniformly penetrated with three positioning threaders 6, the outer annular surface of the turntable 4 and located on the outside of the electric rotary drum 3 are uniformly fixedly connected with three connecting seats 7 from the top to one side, a fastening bolt 8 is penetrated through the back of a connecting seat 7, one end of the fastening bolt 8 extends to the top of the back of the electric rotary drum 3, the electric rotary drum 3 is a kind of rotating device for rotating The invention relates to a device for rotating and positioning objects, which is usually driven by an electric motor to rotate the cylinder, and can realize precise rotation control, and is convenient for various operations. The electric rotating drum 3 is connected to an external power supply and is provided with a power control switch. The polyester yarn can pass through the front of the fixed cylinder 5 and pass through the back of the turntable 4 to realize stable transportation of the polyester yarn. The electric rotating drum 3 is rotatably connected to the load-bearing frame 2, and the connecting seat 7 is fixedly connected to the back of the electric rotating drum 3 by a fastening bolt 8. The electric rotating drum 3 is fixedly connected to the fixed cylinder 5, and the front of the fixed cylinder 5 is flush with the front of the electric rotating drum 3. An annular through hole is opened between the front and back of the turntable 4, and the inner ring surface of the turntable 4 and the outer cylinder surface of the fixed cylinder 5 are rotatably connected through a bearing. The front and back of the fixed cylinder 5 are both open, and the interior of the fixed cylinder 5 is connected with the interior of the turntable 4.
[0024] See also Figures 2-4, the positioning wire threading device 6 includes a connecting rod 61. The connecting rod 61 is rotatably connected to the front surface of the turntable 4 through a rotating shaft and is located between the inner cylindrical surface of the electric rotating cylinder 3 and the outer cylindrical surface of the fixed cylinder 5. The other end of the connecting rod 61 is hinged with a transmission rod 62 through a pin shaft. One end of the transmission rod 62 penetrates through the outer cylindrical surface of the fixed cylinder 5 and extends into the interior of the fixed cylinder 5. A positioning ring 63 is fixedly connected to one end of the transmission rod 62. A wire hole 64 is formed between the two sides of the positioning ring 63. A soft rubber ring 65 is fixedly sleeved on the inner wall of the wire hole 64. Since the position of the wire hole 64 causes an angle to be formed between the surface of the texturing yarn and the polyester filament, when the wire hole 64 is closer to the surface of the polyester filament, the number of wound thread turns will be relatively dense, making the polyester filament after multifilament texturing have a greater elasticity. On the contrary, when the position of the wire hole 64 is farther from the surface of the polyester filament, the polyester filament after multifilament texturing will have a smaller elasticity. Thus, polyester filaments with different elasticities can be produced according to requirements. The connecting rod 61 is in contact with the fixed cylinder 5, and the included angle between the connecting rod 61 and the transmission rod 62 is 95°. Each wire hole 64 inside the positioning wire threading device 6 can penetrate a texturing yarn for the overall multifilament texturing process of the polyester filament.
[0025] Specific implementation method: The polyester filament is stably conveyed by threading it through the front surface of the fixed cylinder 5 and out through the back surface of the turntable 4. Then, three texturing yarns are respectively penetrated through the wire holes 64 inside the three positioning wire threading devices 6 and out through the back surface of the turntable 4, and are conveyed simultaneously with the polyester filament. The electric rotating cylinder 3 is started simultaneously to drive the fixed cylinder 5 and the turntable 4 to rotate self - sufficiently, thereby driving the three positioning wire threading devices 6 to revolve. Then, the three texturing yarns can be continuously wound around the surface of the conveyed polyester filament, thus realizing the multifilament texturing process of the polyester filament.
[0026] When it is necessary to adjust the elasticity of the polyester filament after texturing, the fastening bolt 8 can be directly rotated and disassembled to release the connection between one connecting seat 7 and the back surface of the electric rotating cylinder 3. The turntable 4 is rotated counterclockwise through one connecting seat 7, thereby driving one end of the connecting rod 61 inside the three positioning wire threading devices 6 to rotate from left to right. Then, the relative ends of the three transmission rods 62 can be pushed to move simultaneously towards the center of the fixed cylinder 5, and then the position of the wire hole 64 can be adjusted. After the adjustment is completed, the other connecting seat 7 is fixedly connected to the electric rotating cylinder 3 through the fastening bolt 8, and the multifilament texturing process of the polyester filament can continue. Since the position of the wire hole 64 causes an angle to be formed between the surface of the texturing yarn and the polyester filament, when the wire hole 64 is closer to the surface of the polyester filament, the number of wound thread turns will be relatively dense, making the polyester filament after multifilament texturing have a greater elasticity. On the contrary, when the position of the wire hole 64 is farther from the surface of the polyester filament, the polyester filament after multifilament texturing will have a smaller elasticity. Thus, polyester filaments with different elasticities can be produced according to requirements, effectively increasing the variety quantity of polyester filaments produced by the multifilament texturing device and saving the equipment cost for polyester filament production and processing.
[0027] Inside each wire hole 64, there is a soft rubber ring 65 sleeved, which effectively avoids the rubbing between the texturing yarn and the positioning ring 63 during the conveying process, prevents the occurrence of wire breakage and the interruption of the multifilament texturing work, and effectively improves the processing efficiency of the polyester filament.
