Description

Technical Field

[0001] This utility model relates to the field of cleanroom cloth weaving technology, specifically a device for optimizing the weaving structure of Class 100 ultrafine cleanroom cloth. Background Technology

[0002] Class 100 ultrafine cleanroom wipes are high-performance cleaning materials suitable for Class 100 cleanroom environments. Woven from ultrafine fibers, they have a smooth surface free of excess lint and knots. A special combing process reduces lint impurities and short fibers, minimizing dust generation at the source. The regularly arranged fibers ensure even stress distribution, resulting in strong and consistent dust collection and removal stability. They efficiently remove micro-dust from the surfaces of precision instruments and electronic components, meeting the stringent cleaning requirements of high-cleanliness environments and making them a key cleaning consumable in precision manufacturing.

[0003] The self-adjusting shuttleless loom structure, authorized by announcement number CN117888261B, relates to the technical field of shuttleless looms. It solves the problem that multiple sets of drive components need to operate simultaneously during the weaving process, resulting in high costs and significant vibration and noise that affect fabric quality. This loom structure includes a machine housing, a clamping assembly, two sets of guide rollers, a weaving roller, a self-adjusting weaving mechanism, and a control console. The clamping assembly is installed on the inner side of one end of the machine housing, positioning the unwinding roller. Two sets of guide rollers are arranged on the side of the clamping assembly, installed inside the machine housing, with the weaving roller also positioned on the side of the guide roller. In this invention, while automating the winding of the woven fabric, the raising and lowering of the yarn and the pushing of the yarn can be performed simultaneously, ensuring the woven fabric has a mesh structure and guaranteeing its toughness and quality.

[0004] As shown in the above equipment, the existing Class 100 ultrafine cleanroom cloth weaving structure optimization device can simultaneously realize the lifting and pushing of the yarn when automatically winding the textile fabric, ensuring that the fabric has a mesh structure and toughness and quality. However, due to the lack of a yarn combing structure, it cannot remove impurities, oil stains and loose fibers from the surface of the yarn. These pollutants will be continuously released during weaving, resulting in excessive particle count in the production environment and damage to the Class 100 clean environment. Ultimately, the cleanliness of the woven cleanroom cloth will not meet the standards and cannot meet the requirements of high-precision scenarios such as electronic chip manufacturing.

[0028] See Figures 1-6 This utility model provides the following two technical solutions:

[0029] First implementation: A woven structure optimization device for Class 100 ultrafine cleanroom cloth, including an optimization chamber 1, and further comprising:

[0030] Combing structure 6 is located on the inner wall of optimization chamber 1 and is used to comb and clean the yarn used for Class 100 ultrafine cleanroom fabric weaving, thereby optimizing the woven products.

[0031] The wire drive structure 7 is set on the outer wall of the optimization chamber 1 and is used for conveying and introducing the yarn material during the weaving of Class 100 ultrafine cleanroom cloth.

[0032] The cleaning linkage structure 8 is set on the inner wall of the optimization chamber 1 and is used to clean the dust that falls from the wire material when it is combed by the wire transmission structure 7.

A limit slide groove is opened on the outer wall of the optimization chamber 1. A dust collection box 3 is slidably connected to the outer wall of the limit slide groove.

[0034] The combing structure 6 includes a screw plate 61, which is fixedly installed on the outer wall of the optimization chamber 1 by bolts. One end of the screw plate 61 is fixedly connected to a curved frame 62, one end of the curved frame 62 is fixedly connected to a tension rod 63, one end of the tension rod 63 is fixedly connected to a rotating plate 65, and one end of the rotating plate 65 is provided with a combing and cleaning component 64.

[0035] The grooming and cleaning component 64 includes a grooved plate 641, with connecting screws fixedly connected to both ends of the grooved plate 641. The grooved plate 641 is threadedly connected to the rotating plate 65 via the connecting screws. A material passage groove 642 is formed on the outer wall of the grooved plate 641. A connecting component 643 is provided on the outer wall of the grooved plate 641. A pull slide 644 is provided at the top of the connecting component 643. A retaining plate 645 is fixedly installed at one end of the pull slide 644. A cleaning brush 646 is provided at the bottom of the connecting component 643.

[0036] The connecting component 643 includes a slide plate 6431, which is disposed on the inner wall of the groove plate 641. The outer wall of the slide plate 6431 is slidably connected to the pull slide 644. A limit plate 6432 is fixedly installed on the outer wall of the slide plate 6431.

[0037] The woven structure optimization device of this Class 100 ultrafine cleanroom cloth is equipped with a combing structure 6. In the cleaning component, the cleaning brush 646 can effectively remove impurities and loose fibers from the surface of the yarn. In conjunction with the feed groove 642, the combing is limited, reducing the dust and short fibers carried by the yarn itself.

The combing angle and tension can be adjusted by the tension rod 63 and the rotating plate 65. The connecting component 643 ensures the stable cooperation between the pull carriage 644 and the cleaning brush 646, so that the yarn is evenly stressed and the fibers are arranged in a regular manner, avoiding defects such as fuzz and knots on the fabric surface, improving flatness, and enhancing the stability and consistency of dust collection and cleaning.

[0038] The second embodiment differs from the first embodiment in that the wire transmission structure 7 includes a mounting plate 71, which is fixedly mounted on the outer wall of the optimization chamber 1. One end of the mounting plate 71 is fixedly connected to a drive motor 72, and the output end of the drive motor 72 is fixedly connected to a bidirectional lead screw 73 via a coupling. A wire seat 75 is threadedly connected to the outer wall of the bidirectional lead screw 73. A slide rod 74 is fixedly mounted on the outer wall of the mounting plate 71 for limiting the movement of the wire seat 75. The other end of the slide rod 74 is fixedly connected to an L-shaped plate 79, and the other end of the bidirectional lead screw 73 is fixedly connected to a transmission gear 76. The rotation of the transmission gear 76 is connected to the outer wall of the L-shaped plate 79, and a gear shaft A77 meshes with the outer wall of the transmission gear 76. One end of the gear shaft A77 is fixedly connected to a transmission wheel A78.

[0039] The optimized woven structure device for the Class 100 ultrafine cleanroom cloth is equipped with a wire transmission structure 7. The drive motor 72 drives the bidirectional lead screw 73, which, together with the slide bar 74, allows the wire seat 75 to precisely adjust the position of the wire material feeding, ensuring stable wire material feeding. At the same time, the bidirectional lead screw 73 is linked to the transmission gear 76, gear shaft A77 and transmission wheel A78, providing power to the cleaning linkage structure 8, realizing the coordination of wire material feeding and dust removal, and improving the overall operating efficiency and optimization effect of the device.

[0040] The cleaning linkage structure 8 includes a gear shaft B81, which is rotatably connected to the outer wall of the optimization chamber 1. The outer wall of the gear shaft B81 meshes with a limiting toothed plate 85. The outer wall of the limiting toothed plate 85 is slidably connected to a limiting groove plate 84. The limiting groove plate 84 is fixedly installed on the inner wall of the optimization chamber 1. A cleaning plate 86 is fixedly installed on the outer wall of the limiting toothed plate 85. A transmission wheel B82 is fixedly connected to one end of the gear shaft B81. A transmission belt 83 is sleeved on the outer wall of the transmission wheel B82. The transmission wheel B82 is connected to the transmission wheel A78 through the transmission belt 83.

[0041] The woven structure optimization device for this Class 100 ultrafine cleanroom cloth is equipped with a cleaning linkage structure 8. Powered by the wire transmission structure 7, the dust is driven by the transmission belt 83 and other linkages, gear shaft B81, limit tooth plate 85, etc., to drive the cleaning plate 86 to clean and comb the dust in a timely manner. The dust is guided by the inclined plate 4 and the material drop chute 5 into the dust collection box 3, ensuring the cleanliness of the optimization chamber 1, reducing the burden of manual cleaning, creating a clean environment for weaving, and helping to improve the quality of the cleanroom cloth.

[0042] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0043] When the woven structure optimization device for the Class 100 ultrafine cleanroom cloth is working, the yarn is fed into the optimization chamber 1 via the wire transmission structure 7. Inside the wire transmission structure 7, the drive motor 72 on the mounting plate 71 starts, driving the bidirectional lead screw 73 to rotate, causing the wire seat 75 to move along the slide rod 74 to adapt to the yarn feeding. The rotation of the bidirectional lead screw 73 also causes the transmission gear 76 to rotate, which in turn drives the transmission wheel A78 to rotate via the gear shaft A77. After the yarn enters the optimization chamber 1, the combing structure 6 takes effect. The curved frame 62 fixed by the screw hole plate 61 adjusts the angle of the rotating plate 65 via the tension rod 63. The groove plate 641 of the combing and cleaning component 64 has a feed groove 642 for the yarn to pass through, pulling the slide 644 to slide along the slide plate 6431 of the connecting component 643. With the cooperation of the return spring 6434 and the clamping plate 645, the cleaning brush 646 connected to the slide rail plate 6435 combs the yarn, removing impurities. The dust generated during combing is collected in the feed chute 5 of the inclined panel 4. In the cleaning linkage structure 8, the transmission wheel A78 drives the transmission wheel B82 to rotate via the transmission belt 83, causing the gear shaft B81 to mesh with the limiting tooth plate 85. The limiting tooth plate 85 slides along the limiting groove plate 84, driving the cleaning plate 86 to sweep the dust into the dust collection box 3. Finally, the optimized yarn enters the loom in the loom housing 2, completing the optimization of the woven product.
