Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of polyester spinning guide, in particular to a spinning guide for DTY polyester draw texturing yarn processing. BACKGROUND

[0002] Due to the rapid development of the textile industry, the textile machine is required to have the ability to withstand high speed and wear resistance, so the metal guide cannot meet the requirements of modern textile industry, and the ceramic has many excellent properties that the metal does not have. In the early 20th century, ceramic guide was introduced into the textile industry. In the production and processing of fibers and the subsequent textile production, the rotating ceramic guide is one of the most common guides. Its characteristics are that when the yarn passes through the slot on the ceramic guide, the ceramic guide will rotate, thereby reducing the friction resistance generated during the guiding process, reducing the broken ends or large neps of the yarn due to friction, and improving the work efficiency and the qualified rate of the yarn. However, since each yarn is in constant contact with the guide, each contact will generate about 1s of friction, and the high-frequency friction process will cause the yarn to shed flying hair, which will block the rotating shaft when gathered in the inner part of the ceramic guide rotating wheel, thereby reducing the production efficiency or even making it difficult to guide the yarn.

[0003] Patent No. CN202122343554.X discloses a spinning guide for a draw texturing machine that improves the performance of yarn.

The inner side plate is fixed on the installation support through the threaded rod, and the roller is sleeved on the fixed seat. The spinning guide for the draw texturing machine improves the performance of yarn. When the yarn is introduced through the roller, the friction with the roller is reduced, thereby reducing the generation of burrs on the yarn introduced on the outer side of the roller, reducing the tension, and enhancing the service life. However, the device has the following problems: first, the polyester guide cannot realize uniform heating and stretching, and is prone to uneven heat shrinkage; second, the polyester quenching is prone to breakage, and the device has single structure and poor practicability.

[0039] Further, as shown in the figure, Figure 6 The right side center position of the heating block 6 is fixedly connected with the threaded column 65, the right side end of the threaded column 65 is provided with a circular hole 651, the adjusting handle 66 is transversely connected in the circular hole 651, the upper and lower ends of the adjusting handle 66 are provided with limiting spherical balls 661, the adjusting handle 66 is used to rotate the threaded column 65 to adjust the position distance of the heating block 6, the limiting spherical balls 661 are used to prevent the adjusting handle 66 from falling down from the position of the circular hole 651, and the principle of human engineering is met, so that the worker is more convenient to exert force when rotating the adjusting handle 66, the threaded column 65 is threadedly connected with the ventilation pipeline 4, and the hole position is arranged at the threaded connection position of the threaded column 65 and the ventilation pipeline 4, so that the air flow in the ventilation pipeline 4 is turned around the heating block 6, and multiple hole positions are arranged on the hollow column body of the threaded column 65, so that internal heat dissipation and ventilation are ensured.

[0040] Further, the groove 52 and the protrusion 53 are both arranged at an angle of 20 degrees, and the groove 52 can coincide with the guide wire channel 61, and the protrusion 53 can coincide with the installation limiting protrusion 62, the inclination of the groove 52 and the protrusion 53 is limited, so that the polyester yarn can pass through the longer guide wire channel 61 without scratching the polyester yarn due to excessive inclination, and the structure is simple and practical.

[0042] Further, as shown in the figure, Figure 2 The fine adjustment structure 7 includes an abutting block 71, the right side of the abutting block 71 is provided with the adjusting rectangular block 131, and a threaded hole is formed in the center of the abutting block 71. The adjusting column 72 is threadedly connected in the threaded hole, the left side end of the adjusting column 72 is provided with a second handle 73, the abutting block 71 abuts against the adjusting rectangular block 131, the second handle 73 is rotated to drive the adjusting column 72 to rotate, the adjusting column 72 rotates in the threaded hole, and then the abutting block 71 is connected to the inner wall of the protective cover 2. Then the adjusting column 72 extends out of the threaded hole and abuts against the adjusting rectangular block 131, which is used to adjust the position of the disc 1 and the second disc 11, and ensures that the meshing connection of the rotating gear 14 and the second rotating gear 15 is more perfect.

[0043] Working process: first, the rotating handle 141 on the rotating gear 14 is rotated to drive the rotating gear 14 and the second rotating gear 15 to mesh, the position of the blower mechanism 3 connected with the sliding block 21 is adjusted, and then the height of the sliding block 21 is limited. The sliding block 21 slides on the right side of the protective cover 2, and when the position needs to be limited, a screw is placed in the hole on the sliding block 21 to fix the position. Of course, the right side of the protective cover 2 is provided with a connecting circular hole;

[0044] Secondly, the blowing mechanism 3 starts to work, the motor 34 starts to work to drive the fan blade 33 to start rotating, the rotation of the fan blade 33 makes the ventilation pipe 4 start to ventilate, the wind enters the ventilation block 5, and the wind speed of the wind out of the ventilation pipe 4 cannot be too fast through the ventilation of the heat dissipation hole 521 in the baffle 51 and the groove 52, not only the speed of the air flow can be blocked, but also the other side of the ventilation pipe 4 can act on the heating block 6, thereby improving the heating speed of the heating block 6, so that the polyester filament can be uniformly heated when passing through the guide wire channel 61, and is uniformly stretched when passing through the guide wire channel 61;
