Description

Technical Field

[0001] This utility model relates to the field of carpet yarn processing technology, specifically a carpet yarn stretching and swelling device. Background Technology

[0002] In the production of recycled polyester BCF expanded filament, the industrial frequency hot roller, as the core component of the drafter, works in conjunction with the airflow rotary disc expander to achieve a one-step spinning process. By precisely controlling the temperature of the hot roller (usually 180-220℃) and the stretch ratio, the melt fiber can form a stable three-dimensional crimp structure during the expansion process, thereby improving the bulk and elasticity of carpet yarn.

[0003] However, during the stretching and swelling process of carpet yarn, the lack of surrounding sound insulation and protection structures leads to the superposition of airflow noise generated by the high-speed fan, motor vibration noise, and yarn impact noise inside the swelling chamber, which are transmitted to the surrounding environment, causing noise pollution. Long-term exposure can easily cause hearing damage to workers and cannot meet the needs of personnel. Utility Model Content

[0004] The purpose of this utility model is to provide a carpet yarn stretching and swelling device with a sound insulation and protection structure, which effectively reduces the probability of noise diffusion during operation and is convenient for personnel to use.

At the same time, the setting of the pin 15, support spring 8, slot 14, push rod 10, adjusting plate 13 and fixing frame 4 facilitates the opening of the L-shaped movable cover 9 and the soundproof cover 6. During the opening process, the L-shaped movable cover 9 is supported, which facilitates the inspection and maintenance of the power frequency hot roller 20 and the airflow rotary disc expander 19, making it convenient for personnel to use.

[0025] Example 2:

[0026] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, a first sound-insulating cotton board 17 is fixedly connected to the middle of the soundproof cover 6, a second sound-insulating cotton board 21 is fixedly connected to the middle of the L-shaped movable cover 9, a hollow glass plate 2 is fixedly connected to the front surface of the L-shaped movable cover 9, a reinforcing rib 11 is fixedly connected to the middle of the push rod 10, support guide wheels 5 are movably connected to the lower ends of both sides of the outer surface of the soundproof cover 6 via bearings, and support plates 7 are fixedly connected to the upper ends of both sides of the outer surface of the soundproof cover 6. The upper ends of the support plates 7 are movably connected to the L-shaped movable cover 9 via bearings. At the upper end of the cover 9, a guide slide rod 12 is fixedly connected to the front surface of the fixed frame 4. The surface of the adjusting plate 13 is movably connected to the lower end of the guide slide rod 12. Both ends of the pin 15 are movably connected to the limiting slide rod 22. The surface of the limiting slide rod 22 is fixedly connected to the surface of the receiving hole 18. A pressure rod 16 is fixedly connected to the middle end of the pin 15. A pressure plate is fixedly connected to the surface of the pressure rod 16. Support columns 3 are fixedly connected to the four sides of the bottom of the support platform 1. A support base plate is fixedly connected between the bottoms of the two support columns 3.

[0027] In this technical solution, the sound insulation effect of the soundproof cover 6 and the L-shaped movable cover 9 is effectively improved by setting the first soundproof cotton board 17 and the second soundproof cotton board 21. The hollow glass plate 2 facilitates the observation of the working status inside the soundproof cover 6 and the L-shaped movable cover 9 by personnel.

The limiting slide rod 22 limits the pin 15 to the receiving hole 18 to prevent the pin 15 from detaching from the surface of the receiving hole 18. The pressure rod 16 and the pressure plate facilitate personnel to press and push the pin 15. The support column 3 and the support base plate support the bottom of the support platform 1.

[0028] The working principle of this utility model is as follows: By setting up the soundproof cover 6 and the L-shaped movable cover 9, sound insulation protection can be provided at the top of the support platform 1 and around the industrial frequency hot roller 20 and the airflow rotating disk expander 19 during the stretching and expansion of the carpet yarn. This effectively reduces the probability of noise spreading into the environment during operation and improves the noise reduction effect during processing. Furthermore, when personnel need to perform internal inspection and maintenance work, the support spring 8 can be compressed by pressing the pin 15 until the pin 15 can move out of the slot 14. After the lower end detaches, personnel can pull the L-shaped movable cover 9 to rotate and open it. At the same time, the L-shaped movable cover 9 can drive the push rod 10, the adjusting plate 13 and the pin 15 to move upward until the pin 15 can be inserted into the upper end of the slot 14 under the tension of the support spring 8. This limits the position between the adjusting plate 13 and the fixed frame 4, and allows the push rod 10 to support the L-shaped movable cover 9. This makes it convenient for personnel to carry out maintenance and repair work on the power frequency hot roller 20 and the airflow rotary disc expander 19, and is easy for personnel to use.
