Description

Technical Field

[0001] The utility model relates to the technical field of equipment, in particular to a sizing and dehydrating device for producing polyester filter cloth. Background Art

[0002] In the production process of polyester filter cloth, sizing and dehydration are two key steps. Sizing refers to applying a layer of sizing on the surface of polyester fiber to improve its strength and filtration performance. Dehydration refers to removing excess water generated during the sizing process to ensure the quality and performance of the filter cloth.

[0003] Traditional sizing and dehydration methods usually involve multiple independent processes, which not only increases production costs, but also may affect production efficiency and product quality. Therefore, the development of a device that integrates sizing and dehydration functions is of great significance to improve the production efficiency and quality of polyester filter cloth.

[0004] However, when the sizing and dehydration functions are simply integrated, the side edges of the filter cloth are usually difficult to be sufficiently wetted during the sizing process, and the side edges of the filter cloth are usually easy to fall off from the limiting devices such as the clamping blocks.

DETAILED DESCRIPTION

[0022] The utility model provides a sizing and dehydrating device for producing polyester filter cloth, such as Figure 1-4 As shown, it includes an outer shell 11, an upper pulping cavity 12, a first slot 13, a first rotating shaft 14, a guide roller 15, a second rotating shaft 16, a dewatering roller 17, a second slot 18, a first slider 19, a limiting bottom plate 20, a limiting inner plate 21, a limiting outer plate 22, a third rotating shaft 23, a rotating arm 24, a third slot 27, a limiting block 28, and a spring 29.

[0023] like Figure 1-4 As shown, an upper sizing chamber 12 is opened in the outer shell 11, and first grooves 13 are opened on both end surfaces of the outer shell 11. A first rotating shaft 14 is rotatably connected in the upper sizing chamber 12, and a guide roller 15 is fixedly connected to the outer circumferential surface of the first rotating shaft 14. A sizing assembly and a dehydration assembly are arranged on the upper sizing chamber 12. The sizing assembly includes a limiting bottom plate 20, a third rotating shaft 23 and a rotating arm 24. The third rotating shaft 23 is rotatably connected to a side wall of the upper sizing chamber 12, one end of the rotating arm 24 is fixedly connected to the rotating arm 24, and the other end of the rotating arm 24 is fixedly connected to the limiting bottom plate 20.

[0024] It is worth noting that a winding device is provided on the outside of the outer shell 11, which provides power for the transportation of the polyester filter cloth in the outer shell 11. The third rotating shaft 23 is externally connected to a driving device, which is used to drive the third rotating shaft 23 to rotate periodically reciprocatingly. The driving device is a prior art. The liquid level of the sizing liquid in 12 does not exceed the first slot 13 and the two dewatering rollers 17, and the limiting bottom plate 20 is elliptical.

[0025] The dehydration assembly includes two second rotating shafts 16, a limit block 28 and a spring 29. The outer circumferential surfaces of the two second rotating shafts 16 are fixedly connected to the dehydration rollers 17. Both ends of the second rotating shafts 16 are rotatably connected to the limit blocks 28. A third groove 27 is provided on both side walls of the upper pulping chamber 12. One of the limit blocks 28 on one side of the two second rotating shafts 16 is slidably connected to the third groove 27, and the other limit block 28 is fixedly connected to the third groove 27. Both ends of the spring 29 are fixedly connected to the two limit blocks 28 respectively.

[0026] A limiting inner plate 21 and a limiting outer plate 22 are fixedly connected to the limiting bottom plate 20. The limiting outer plate 22 is semi-elliptical. A limiting seam is set between the limiting inner plate 21 and the limiting outer plate 22. The limiting seam is used to limit the polyester filter cloth. The lengths of the major axis and the minor axis of the limiting inner plate 21 are respectively smaller than the lengths of the major axis and the minor axis of the limiting bottom plate 20, and the lengths of the major axis and the minor axis of the limiting outer plate 22 are respectively equal to the lengths of the major axis and the minor axis of the limiting bottom plate 20.

[0027] A second slot 18 is formed on one side wall of the upper slurry chamber 12, and a first slider 19 is fixedly connected to one end of the limiting bottom plate 20 away from the limiting inner plate 21, and the first slider 19 is slidably connected to the second slot 18. The second slot 18 is an arc-shaped slot.

[0028] When the present scheme is used for sizing and dehydrating the polyester filter cloth, first, the polyester filter cloth is fed from the first slot 13 on one side into between the two first rotating shafts 14 on the side close to the limiting bottom plate 20, and then the edge of the polyester filter cloth is passed through between the limiting inner plate 21 and the limiting outer plate 22, and then the polyester filter cloth is sequentially fed into between the two dehydration rollers 17 and between the two first rotating shafts 14 on the side away from the limiting bottom plate 20, and is fed out from the first slot 13 on the other side.

[0029] Then, the driving device drives the third rotating shaft 23 to rotate, and the third rotating shaft 23 drives the limiting base plate 20 to rotate around the third rotating shaft 23 through the rotating arm 24. The limiting base plate 20 slides along the trajectory of the second slot 18 through the first slider 19, and the limiting inner plate 21 and the limiting outer plate 22 follow the limiting base plate 20 to rotate around the third rotating shaft 23 as the axis core. The limiting inner plate 21 and the limiting outer plate 22 immerse the polyester filter cloth in the sizing liquid.

[0030] Finally, when the polyester filter cloth passes between the two dehydration rollers 17, the polyester filter cloth increases the distance between the two dehydration rollers 17, and the dehydration roller 17 increases the distance between the two limit blocks 28 through the second rotating shaft 16. The spring 29 generates a pulling force on the limit blocks 28 at both ends, so that the limit blocks 28 generate a force on the dehydration roller 17 through the second rotating shaft 16 to bring the two dehydration rollers 17 closer to each other, thereby completing the dehydration of the polyester filter cloth.

[0031] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
