Description

Technical Field

[0001] This application relates to the field of fabric conveying, and particularly to a curved roller device for flattening fabrics. Background Art

[0002] In the process of fabric production, after the water washing process of the woven fabric is completed, a drying machine is used to dry and shape the fabric. After the water washing is completed, the fabric is generally conveyed to the drying machine by multiple conveying rollers, and the fabric is in a traction state. Affected by mechanical movement and production operations, the weft yarn of the fabric will be skewed or bent before entering the drying machine. After being dried and shaped by the drying machine, the skewed or bent weft yarn of the fabric will be in a deformed state, affecting the subsequent processing of the fabric and thus the production quality of the fabric. Therefore, before the fabric is dried and shaped, it is usually necessary to straighten the skewed or bent weft yarn.

[0003] In the related art, the fabric is conveyed by multiple conveying rollers, and a bending roller is arranged between two conveying rollers. The fabric passes between the conveying roller and the bending roller, and the arc part of the bending roller abuts against the fabric. The bending roller slides relative to the fabric during the fabric transportation process, thereby trimming the weft yarn of the fabric.

[0004] In view of the above related art, since there are various fabrics made of different materials, such as cotton, linen, silk, woolen and chemical fiber, etc., their characteristics and uses are different, so the requirements for the tension during transportation will also be different, making it difficult for the bending roller to trim the weft yarn of fabrics made of different materials.

Detailed Description of the Invention

[0034] The following will further describe the present application in detail with reference to the attached Figures 1 to 3 drawings.

[0035] An embodiment of the present application discloses a curved roller device for leveling fabric. Refer to Figure 1 The curved roller device for leveling fabric includes a mounting rod 1, a rotating roller 2, an adjusting seat 3, and a curved roller 4. There are two mounting rods 1, and the two mounting rods 1 are arranged in parallel. The two ends of the mounting rod 1 are respectively connected to the fabric conveying device, so as to facilitate the installation of the entire curved roller device.

[0036] Two rotating seats 11 are fixed on each mounting rod 1. There are two rotating rollers 2, and the two ends of the rotating roller 2 are respectively rotatably connected to the rotating seats 11 at corresponding positions on the two mounting rods 1, so as to realize the rotational connection between the rotating roller 2 and the mounting rod 1. The length direction of the rotating roller 2 is perpendicular to the length direction of the mounting rod 1. The adjusting seat 3 is installed on the mounting rod 1. The curved roller 4 is located between the adjusting seats 3 of the two mounting rods 1, and the curved roller 4 is connected to the adjusting seat 3 through a height adjusting component 31. The height adjusting component 31 is used to adjust the position of the curved roller 4, and the adjusting direction of the curved roller 4 is perpendicular to the length direction of the mounting rod 1 and the length direction of the rotating roller 2.

[0037] The fabric passes over the top of one of the rotating rollers 2, passes under the curved roller 4, and then passes over the top of the other rotating roller 2. The conveying device behind the fabric is used to pull the fabric to realize the movement of the fabric. Since the middle part of the curved roller 4 arches towards the advancing direction of the fabric, the skewed weft yarns on the fabric can be rectified. In addition, after replacing fabrics of different materials, according to the tension requirements of the fabrics of corresponding materials, the height of the curved roller 4 is adjusted to adjust the tension of the fabric between the rotating roller 2 and the curved roller 4, so as to adapt to the tension requirements of fabrics of different materials.

[0038] Refer to Figure 1 and Figure 2 Preferably, the height adjusting component 31 includes a limiting cylinder 311 and a height adjusting screw 312. The limiting cylinder 311 is fixedly connected to the end of the curved roller 4. A sliding opening 32 is provided on the adjusting seat 3. The end of the curved roller 4 can extend into the sliding opening 32, so that there is a space for relative sliding between the curved roller 4 and the adjusting seat 3. A limiting circular opening 33 is provided on the adjusting seat 3, and the limiting circular opening 33 communicates with the sliding opening 32. The limiting cylinder 311 can extend into the limiting circular opening 33, so that there is a space for relative sliding between the limiting cylinder 311 and the adjusting seat 3. The height adjusting screw 312 is threadedly disposed on the adjusting seat 3, and the end of the height adjusting screw 312 can abut against the outer side of the limiting cylinder 311. In addition, a knob 3121 is fixed to the end of the height adjusting screw 312, which is convenient for rotating the height adjusting screw 312 through the knob 3121.

[0039] When it is necessary to adjust the height of the curved roller 4, loosen the height adjustment screw 312 so that the end of the height adjustment screw 312 does not tightly abut against the outer side of the limit cylinder 311. Then, adjust the height of the curved roller 4 according to actual needs, so that the limit cylinder 311 can slide within the limit circular opening 33 and the curved roller 4 can slide within the sliding opening 32. After adjusting the height of the curved roller 4, tighten the height adjustment screw 312 so that the end of the height adjustment screw 312 abuts against the outer side of the limit cylinder 311 again, thereby fixing the position of the curved roller 4.

[0040] In addition, both the upper and lower ends of the limit circular opening 33 are open, and both the upper and lower ends of the sliding opening 32 are open. With such a setting, when disassembling and assembling the curved roller 4, the curved roller 4 can be taken out or put in through the opening of the sliding opening 32, and the limit cylinder 311 can be taken out or put in through the opening of the limit circular opening 33, thereby facilitating the disassembly, assembly, and replacement of the curved roller 4.

[0041] Furthermore, a tightening vertical groove 3111 is formed on the outer side of the limit cylinder 311. The length direction of the tightening vertical groove 3111 is parallel to the length direction of the limit cylinder 311, and the height adjustment screw 312 is in contact and cooperation with the tightening vertical groove 3111. With such a setting, the contact area between the end of the height adjustment screw 312 and the limit cylinder 311 can be increased, so that the limit cylinder 311 can be more stably tightened, thereby improving the stability of the curved roller 4.

[0042] Refer to Figure 3 , preferably, both the curved roller 4 and the limit cylinder 311 are hollow. Both opposite ends of the limit cylinder 311 are open, and rubber cylinders 3112 are respectively inserted through both ends of the limit cylinder 311. The cross-section of the rubber cylinder 3112 is in a T shape. The hollow curved roller 4 and limit cylinder 311 can save materials and reduce the weight of the curved roller 4 and the limit cylinder 311. Moreover, setting the rubber cylinders 3112 at the ends of the limit cylinder 311 can seal the ends of the limit cylinder 311, making it difficult for personnel to be cut by the ends of the limit cylinder 311 during operation, thereby improving the safety of operation.

[0043] Refer to Figure 1 and Figure 2 , furthermore, the adjustment seat 3 is specifically a sliding sleeve arranged outside the mounting rod 1. A position adjustment screw 34 is threadedly inserted through the adjustment seat 3, and the position adjustment screw 34 can be in contact and cooperation with the mounting rod 1. Since the adjustment seat 3 and the mounting rod 1 can move relative to each other, the position of the adjustment seat 3 can be adjusted according to actual needs. When it is necessary to adjust the position, first loosen the position adjustment screw 34 so that the end of the position adjustment screw 34 does not tightly abut against the outer side of the mounting rod 1. After the position adjustment is completed, tighten the position adjustment screw 34 so that the end of the position adjustment screw 34 abuts against the outer side of the mounting rod 1 again to fix the position of the adjustment seat 3.

[0044] Preferably, a tightening transverse groove 12 is provided on the outside of the mounting rod 1, the length direction of the tightening transverse groove 12 is parallel to the length direction of the mounting rod 1, and the position adjustment screw 34 is in abutment with the tightening transverse groove 12. Such a configuration can increase the contact area between the end of the position adjustment screw 34 and the mounting rod 1, so that the mounting rod 1 can be tightened more stably to improve stability. In addition, a knob 3121 is also fixed to the end of the position adjustment screw 34, so that the position adjustment screw 34 can be rotated by the knob 3121.

[0045] The implementation principle of a curved roller device for smoothing cloth in an embodiment of the present application is as follows: the cloth passes from the top of one of the rotating rollers 2, passes from the bottom of the curved roller 4, and then passes from the top of the other rotating roller 2, and the conveying device on the rear side of the cloth is used to pull the cloth to realize the movement of the cloth, and because the middle part of the curved roller 4 is arched toward the forward direction of the cloth, the skewed weft yarns on the cloth can be straightened. After replacing cloth of different materials, the height of the curved roller 4 is adjusted according to the tension requirements of the corresponding material cloth, so as to adjust the tension of the cloth between the rotating roller 2 and the curved roller 4, so as to adapt to the tension requirements of cloth of different materials.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
