Description

Technical Field

[0001] This invention relates to the field of spinning equipment, and more particularly to a spinning apparatus for producing polyester filament. Background Technology

[0002] Polyester filament is made from polyester fibers. Polyester is an important type of synthetic fiber and is the commercial name for polyester fiber in my country. It is a fiber-forming polymer—polyethylene terephthalate—obtained from purified terephthalic acid or dimethyl terephthalate and ethylene glycol through esterification or transesterification and polycondensation reactions. The fiber is then produced through spinning and post-treatment. Polyester filament refers to yarns with a length of over one kilometer. The filaments are wound into a bundle. In polyester-nylon composite spinning, the yarn needs to be wound up during the spinning process, and heat dissipation is required during this winding.

[0003] To address the aforementioned issues, patent publication number CN213447409U discloses a polyester-nylon composite spinning device, comprising a fixed outer shell, a side plate fixedly installed on the inner wall of the fixed outer shell, a connecting rod disposed inside the fixed outer shell, and the connecting rod being connected to the fixed outer shell and the side plate respectively via bearings, a driven wheel fixedly installed on the outer wall of the connecting rod, a connecting plate welded to one end of the connecting rod, and the connecting plate being located on the side of the side plate away from the driven wheel, a take-up roller assembly disposed inside the fixed outer shell, the take-up roller assembly being connected to the connecting plate via bolts, a support base welded to one side outer wall of the bottom end of the fixed outer shell, a motor fixedly installed on the top outer wall of the support base, a rotating shaft fixedly connected to the output end of the motor, and the rotating shaft being inserted into the interior of the fixed outer shell, a driving wheel fixedly installed on the outer wall of the rotating shaft, and the driving wheel being located directly below the driven wheel, the driving wheel being connected to the driven wheel via a transmission belt, and a suction fan fixedly installed on one side wall of the fixed outer shell.

[0004] While the above-mentioned solutions accelerate airflow and heat dissipation through suction fans, the high temperature of polyester filaments at the time of ejection makes the heat dissipation effect insufficient. Furthermore, most polyester filament spinning devices are exposed, making them susceptible to contamination from airflow when there is a lot of dust in the environment. Additionally, since polyester filaments must be wound into packages of a specific shape and capacity according to a certain pattern, and with the continuous expansion of the market, most spinning devices simultaneously wind multiple rows of filaments. Due to the long winding time of polyester filaments and the inability to independently adjust the tension of each row when multiple rows are wound simultaneously, if a row of filaments is wound too loosely or breaks, it not only results in idle spinning and wasted filaments but also easily becomes entangled with other finished filaments, leading to further waste during the spinning process. Summary of the Invention

[0009] Furthermore, the No. 1 positioning roller and the No. 2 positioning roller are fitted with several rollers; the guide rollers correspond to the gaps between the two rollers on the No. 2 positioning roller; the thread groove of the oil tank body corresponds to the gap between the two rollers on the No. 1 positioning roller.

[0010] Furthermore, the sensing device includes a fixed roller, the upper surface of which is provided with a movable groove corresponding to the gap between the two rollers on the No. 2 positioning roller, a pressure sensor is provided in the movable groove, a support frame is provided in the pressure sensor, and a movable roller is provided in the support frame; a pressing spring is provided between the support frame and the pressure sensor, and the upper side of the movable roller is higher than the upper surface of the fixed roller.

This prevents the polyester filament from flying and tangling due to wind. At the same time, it realizes automatic protection in polyester filament production, reduces the probability of polyester filament breakage or tangling, and avoids waste of polyester filament in production.

[0023] Example 1:

[0024] like Figures 1-7 As shown, this invention discloses a polyester filament spinning apparatus, including a spinning machine body 1, with a human figure facing the cavity of the spinning machine body 1 defining left and right. A feeding device 3 is provided at the top of the spinning machine body 1, through which the filament enters the spinning machine body 1. To facilitate monitoring and control of the production process, in this embodiment, a control panel 2 is provided on the outer side of the right side plate of the spinning machine body 1. A heat dissipation device 4 is provided on the back plate of the spinning machine body 1 below the feeding device 3. The filament passes directly through the heat dissipation device after exiting the feeding device 3, increasing the airflow area and enhancing the heat dissipation effect. An oiling device 71 is provided on the back plate of the spinning machine body 1 below the heat dissipation device 4. 4. A No. 1 positioning roller 04 is provided on the back plate of the spinning machine body 1 on the right side. A No. 2 positioning roller 10 is provided on the back plate of the spinning machine body 1 below the oiling device 71. Several take-up rollers 9 are provided on the back plate of the spinning machine body 1 on the lower right side of the spinning machine body 1. After cooling and oiling, the yarn is wound on the take-up rollers 9. Each of the back plates of the spinning machine body 1 above the take-up rollers 9 is provided with a corresponding adjustment and limiting device 03. A corresponding guide roller 02 is provided on the back plate of the spinning machine body 1 above the adjustment and limiting device 03. An auxiliary roller 01 is provided on the back plate of the spinning machine body 1 above the guide roller 02. A sensing device 8 is provided on the back plate of the spinning machine body 1 above the No. 1 positioning roller 04.

[0025] like Figure 2 As shown, the heat dissipation device 4 includes a base plate 41, a filter screen plate 42 is provided on one side of the base plate 41, a plurality of cooling plates 43 are provided on the side of the filter screen plate 42 near the base plate 41, a fan assembly 44 is provided on the end face of the cooling plate 43, a refrigeration unit is provided on the base plate 41, and the filter screen plate 42 is installed on the back plate of the spinning machine body 1 with the base plate 41 side of the filter screen plate 42 facing outward. During operation, the refrigeration device 45 cools the cooling plates 43, and the cooled cooling plates 43 exchange heat with the air. The fan assembly 44 blows the cooled air after heat exchange into the spinning machine body 1, and the filter screen plate 42 is used to reduce the entry of dust.

[0026] like Figure 6 , Figure 7 As shown, the oiling device 71 includes an oil tank 711. A connecting frame 72 is provided on the lower side of the oil tank 711. A telescopic rod 74 is provided at one end of the connecting frame 72, and a pressing plate 75 is provided at one end of the telescopic rod 74. A locking block 76 is provided on the side of the pressing plate 75 near the connecting frame 72, and a locking groove 73 is provided on the side of the connecting frame 72 near the pressing plate 75. When the sensing device 8 detects a decrease or disappearance of pressure, the telescopic rod 74 retracts, causing the locking block 76 to lock the thread into the locking groove 73, preventing the thread from breaking and becoming entangled. A thread groove 718 is provided on the side of the oil tank 711 near the pressing plate 75. The thread groove 718 is shaped like a semi-inverted frustum, and a ball bearing 712 is rotatably mounted on the upper end of the thread groove 718. An oil cavity 713 is provided at the upper end of the oil tank 711, and the ball bearing 712 is embedded in the oil cavity 713 on the side near the thread groove 718. An oil supply pipe 715 is provided on one side of the oil tank body 711. One end of the oil supply pipe 715 is connected to the oil cavity 713 inside the oil tank body 711, and the other end is provided with an oil storage tank 717. An oil pump 716 is provided on one side of the oil storage tank 717. A liquid full stop valve 714 is provided in the oil cavity 713. In order to ensure that the ball bearing 712 can continuously carry out oil, the liquid full stop valve 714 is located at a height higher than the lower side of the ball bearing 712 in the oil cavity 713. During normal operation, the wire passes through the wire groove 718, driving the ball bearing 712. Because one side of the ball bearing 712 is embedded in the oil chamber 713, the rotation of the ball bearing 712 carries out the oil in the oil chamber 713, completing the oiling of the wire. When the oil level in the oil chamber 713 is lower than the full stop valve 714, the full stop valve 714 sends an electrical signal to control the operation of the oil pump 716 so that the oil level in the oil chamber 713 is higher than the ball bearing 712, ensuring that the rotation of the ball bearing 712 can continuously carry out oil.

[0027] like Figure 1 , Figure 3 As shown, the No. 1 positioning roller 04 and the No. 2 positioning roller 10 are fitted with several rollers; the guide roller 02 corresponds to the gap between the two rollers on the No. 2 positioning roller 10; the wire groove 718 of the oil tank body 711 corresponds to the gap between the two rollers on the No. 1 positioning roller 04; the rollers are used to limit the position of the wire on the No. 1 positioning roller 04 and the No. 2 positioning roller 10 to prevent the wire from deviating and becoming entangled.

[0028] like Figure 4As shown, the sensing device 8 includes a fixed roller 81. The upper surface of the fixed roller 81 is provided with a movable groove 82 corresponding to the gap between the two rollers on the No. 2 positioning roller 10. A pressure sensor 83 is provided in the movable groove 82. A support frame 84 is provided in the pressure sensor 83. A movable roller 86 is provided in the support frame 84. To reduce vibration and protect the parts and the wire, a pressing spring 85 is provided between the support frame 84 and the pressure sensor 83. The upper side of the movable roller 86 is higher than the upper surface of the fixed roller 81. The wire is wound on the movable roller 86. When the wire is normal, it will apply a force to the movable roller 86. The movable roller 86 is pressed down by the force, which applies force to the pressure sensor 83. When the wire breaks, the force on the pressure sensor 83 will decrease or disappear, thereby sending a signal to press the locking block 73 of the pressing plate 75 into the locking groove 76.

[0029] like Figure 5 As shown, the adjusting and limiting device 03 includes a fixed sleeve 031. An adjusting screw 032 is threaded onto one end of the fixed sleeve 031, and an adjusting head 033 is provided at the other end of the adjusting screw 032. A guide hook 034 is rotatably installed at the other end of the adjusting head 033. The wire passes through the guide hook 034. When a row of wires is too loose or too tight, the length of the adjusting and limiting device 03 can be controlled by adjusting the adjusting screw 032 to adjust the tension of the wire, so that the wire is kept at a certain tension and to prevent the wires from becoming tangled due to slack.

[0030] To reduce the impact of the external environment, a switch door 5 is provided. The switch door 5 is hinged to one side plate of the spinning machine body 1. Because the temperature inside the spinning machine body 1 changes greatly during operation, the switch door 5 can be made of explosion-proof glass while ensuring the visibility inside the spinning machine body 1.

[0031] The spinning machine body 1 has heat dissipation holes 6 on one side plate to increase air circulation inside the spinning machine body 1, increase heat exchange efficiency, and enhance heat dissipation effect.
