Description

Technical Field

[0001] This utility model relates to textile stretching devices, specifically to an automatic uniform oiling device for DTY fiber production. Background Technology

[0002] DTY fiber is a type of textured yarn, which is a finished yarn that is continuously or simultaneously stretched on a texturing machine and then textured by a twister. During the production of DTY fiber, the polyester filaments need to be oiled to improve the coefficient of friction of the fiber, making the fiber smooth, soft and antistatic.

[0003] Chinese Patent Publication No. CN220812933U, published on October 11, 2023, discloses a polyester DTY yarn oiling device, relating to the field of polyester technology. This invention includes a workbench, with a support column fixedly connected to the top of the workbench. A yarn rod is rotatably connected to the side of the support column. An oiling device is installed on the top of the workbench, comprising a movable plate. The bottom of the movable plate is slidably connected to the top of the workbench, and a bracket is fixedly connected to the top of the movable plate. A timer motor is fixedly connected to the side of the bracket, and a threaded rod is fixedly connected to the output shaft of the timer motor. This invention, through the cooperation of the movable plate, threaded rod, timer motor, and rotating disk within the oiling device, achieves the effect of uniformly oiling the DTY stretch deformable yarn by reciprocating left and right movement, reducing friction and minimizing static electricity and uneven strength caused by uneven oil application.

[0004] However, its working principle involves applying oil to the static yarn winding on the yarn bar, and the oiling location is at the winding mechanism, which easily leads to oil waste. At the same time, since the winding process is already at the end of the DTY fiber yarn production process, static electricity and lint are easily generated in the section from before winding to the winding shaft, which can cause problems during winding. Applying oil at this time can only ensure that the yarn used later is as normal as possible, but cannot ensure that the winding is normal. Summary of the Invention

[0005] This invention addresses the shortcomings of existing DTY yarn oiling devices, which often fail to reduce yarn shifting and lint dispersion during winding due to static electricity. Therefore, an automatic and uniform oiling device for DTY fiber production has been designed. The automatic and uniform oiling device for DTY fiber production includes: an inlet roller, a primary impregnation device, a second oiling device, and an outlet roller group arranged sequentially.

[0006] The second oiling device includes a lint collection component;

[0007] Oil is directly supplied to the second oiling device from the oil drum, and the recovered oil collected by the lint collection component is then introduced into the primary soaking device.

[0008] DTY fibers require additional oiling before winding. Therefore, the yarns are arranged at equal intervals from the inlet roller according to the output quantity during production and simultaneously fed into the primary immersion device for the first absorption in oil. They are then fed into the second oiling device for a second absorption. Since the second oiling device includes a concave roller, burrs on the yarn may remain inside. Therefore, a lint collection component is designed to collect lint and oil, and the recovered oil is guided back into the primary immersion device, which also facilitates oil recycling.

[0009] To address the potential issue of insufficient oil absorption by the yarn, additional oiling devices can be added, such as a third oiling device. This device has the same structure as the second oiling device and is arranged with an equal spacing between the initial soaking device and the second oiling device.

[0010] The lint collection component effectively scrapes off any lint-containing oil, minimizing lint interference in the oil tank during secondary absorption and reducing uneven oiling. Simultaneously, due to the concave wheel design, the oil is adsorbed within it and rotates along with the wheel, driven by the threads or a servo motor. In extreme cases, the oil can be completely submerged to the upper horizontal section of the concave wheel to ensure effective oil adsorption.

[0011] Preferably, the primary immersion device includes: an oil tank, with a guide roller installed at the top opening of the oil tank, the lower part of the guide roller cutting into the oil liquid;

[0012] An overflow port is provided on the side of the oil tank;

[0013] The second oiling device includes: an oil tank, with a concave guide roller at the top opening of the oil tank, and a number of concave rollers arranged at equal intervals on the roller body of the concave guide roller;

[0014] The lower horizontal section of the inner ring of the concave guide roller is the oil level;

[0015] A lint collection component is provided in the output direction;

[0016] The guide rollers of the primary immersion device and the concave wheel guide rollers of the second oiling device are on the same horizontal line.

[0017] The oil tanks of the initial soaking device and the second oiling device have the same structure. The oil tank of the second oiling device is directly supplied with oil from the oil tank to the specified liquid level.

[0018] Preferably, the lint collection assembly includes: a tongue plate disposed in front of the filter block, the size of which matches the groove of a single concave wheel of the concave wheel guide roller;

[0019] The tongue plate is positioned between the upper and lower horizontal sections of the concave guide roller;

[0020] The filter block is filled with a lint filter screen and is connected to a recovery pipeline. The recovery pipeline includes a pump body that pumps the oil into the oil tank of the primary soaking device.

[0021] The tongue plate extends deep into the groove formed by the concave wheel, scraping away the oil and removing the lint carried by the oil during lubrication. The oil is then guided along the tongue plate into the filter block area. Under the action of gravity, the oil is filtered by the filter screen, collected, and pumped into the oil tank of the primary soaking device.

[0022] Preferably, the tongue plate is covered with a layer of silicone, the distance between the edge of the silicone and the edge of the tongue plate is greater than or equal to 3mm, and the thickness of the silicone layer is greater than or equal to 1mm.

[0023] Preferably, a heating rod and a temperature sensor are installed on the inner bottom surface of the oil tank.

[0024] Preferably, a servo motor is also provided at the end of the concave guide roller, and the power output end of the servo motor is transmitted to the roller body of the concave guide roller.

[0025] Preferably, a third oiling device is also included between the second oiling device and the output roller group, and the structure of the third oiling device is the same as that of the second oiling device.

[0026] The beneficial effect of this utility model is that by scraping away the lint and fibers in the oil, it allows... Attached Figure Description

Detailed Implementation

[0031] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. Example

[0032] like Figure 1 and Figure 2 As shown, the automatic uniform oiling device for DTY fiber production includes: an inlet roller group 1, a primary impregnation device, a second oiling device, and an outlet roller group 7 arranged in sequence.

[0033] The second oiling device includes a lint collection component;

[0034] Oil is directly supplied to the second oiling device from the oil drum, and the recovered oil collected by the lint collection component is then introduced into the primary soaking device.

[0035] DTY fibers require re-oiling before winding. Therefore, the yarns are arranged at equal intervals from the inlet roller according to the production output quantity and simultaneously fed into the primary impregnation device for the first absorption in oil. They are then fed into the second oiling device for a second absorption. Since the second oiling device includes a concave roller, burrs from the yarn may remain inside. To address this, a lint collection component is designed to collect lint and oil, guiding the recovered oil back into the primary impregnation device, which also facilitates oil recycling. Scraping off any lint-containing oil from the lint collection component effectively reduces interference from lint in the oil tank during the second absorption, minimizing uneven oiling. Simultaneously, due to the concave roller, the oil is adsorbed within it and rotates along the roller, driven by the yarn or a servo motor. In extreme cases, the oil can be completely submerged to the upper horizontal section of the concave roller to ensure effective oil adsorption.

[0036] The primary immersion device includes: an oil tank 3 for the primary immersion device, and a guide roller 2 with an opening at the top of the oil tank, the lower part of the guide roller cutting into the oil liquid;

[0037] An overflow port is provided on the side of the oil tank;

[0038] The second oiling device includes: an oil tank 5 of the second oiling device, a concave guide roller 4 with an opening at the top of the oil tank, and a number of concave rollers arranged at equal intervals on the roller body of the concave guide roller.

[0039] The lower horizontal section of the inner ring of the concave guide roller is the oil level;

[0040] A lint collection component is provided in the output direction;

[0041] The guide rollers of the primary immersion device and the concave wheel guide rollers of the second oiling device are on the same horizontal line.

[0042] The second oiling device supplies oil directly from the oil tank to the designated liquid level.

[0043] The lint collection assembly includes: a tongue plate disposed in front of the filter block 6, the size of which matches the groove of a single concave wheel of the concave wheel guide roller;

[0044] The tongue plate is positioned between the upper and lower horizontal sections of the concave guide roller;

[0045] The filter block is filled with a lint filter screen and is connected to a recovery pipeline. The recovery pipeline includes a pump body that pumps the oil into the oil tank of the primary soaking device.

[0046] The tongue plate extends deep into the groove formed by the concave wheel, scraping away the oil and removing the lint carried by the oil during lubrication. The oil is then guided along the tongue plate into the filter block area. Under the action of gravity, the oil is filtered by the filter screen, collected, and pumped into the oil tank of the primary soaking device.

[0047] Each concave wheel is equipped with a separate lint collection component, so the filter blocks 6 are also arranged in multiple parallel rows and are fixed to the edge of the oil tank 5 of the second oiling device.

[0048] The tongue plate 10 is covered with a layer of silicone 9. The distance between the edge of the silicone and the edge of the tongue plate is 3mm, and the thickness of the silicone layer is 1mm.

[0049] Heating rods and temperature sensors are installed on the inner bottom surface of the oil tank.

[0050] A servo motor is also installed at the end of the concave guide roller, and the power output of the servo motor is transmitted to the roller body of the concave guide roller. Example

[0051] To address the potential issue of insufficient oil absorption by the yarn, additional oiling devices can be added, such as a third oiling device 8. Its structure is identical to the second oiling device, and it is arranged with an equal spacing to that between the initial soaking device and the second oiling device.

[0052] When a third oiling device is present, the oil tank simultaneously supplies oil to the second and third oiling devices. At the same time, the recovered oil from the second and third oiling devices is simultaneously input to the primary immersion device, while the overflow oil from the primary immersion device is then subjected to the normal recovery process.

[0053] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
