Description

TECHNICAL FIELD

[0001] The utility model relates to cloth drive conveying technical field more specifically, the utility model relates to a kind of arc driven roller assembly for preventing cloth wrinkle of low gram weight fabric drive conveying. BACKGROUND

[0002] In the drive conveying process of cloth fabric, to improve the stability of conveying fabric, prevent fabric deviation, arc-shaped driven roller is used in prior art, compared with linear driven roller, it provides an outward supporting force for fabric using the arc-shaped structure of its surface, inhibits the deviation of fabric, so that fabric maintains relatively stable state in transmission process, thereby preventing fabric from wrinkling.

[0003] But in actual production, for the fabric of large gram weight, its deviation-preventing effect is obvious, and the conveying is relatively stable, but when transmitting low gram weight fabric, since fabric is light, such as in the process of preparing elastic cloth by using 5g / m 2 Spunbond cloth is prone to sliding to one side, wrinkling, floating and deviation during turning transmission.

[0004] Therefore, the applicant innovatively designs the arc-shaped driven roller assembly for preventing cloth wrinkling. UTILITY MODEL CONTENT

[0005] The utility model aims at providing an arc-shaped driven roller assembly for preventing cloth wrinkling to solve the problems in the background art.

[0006] To achieve the above object, the utility model provides the following technical scheme.

[0007] An arc-shaped driven roller assembly for preventing cloth wrinkling, comprising a center shaft and an arc-shaped driven roller provided on the center shaft, a support is provided on the center shaft at the outer side of both ends of the arc-shaped driven roller, a support rod parallel to the center shaft is provided on the support, a roller is provided on the support rod, and the outer side of the roller abuts against the surface of the arc-shaped driven roller and rotates with the arc-shaped driven roller.

[0008] The roller comprises a plurality of rollers with different outer diameters.

[0009] A roller washer is provided on the inner side of the roller, and the roller washer has the same size of inner diameter and different sizes of outer diameter.

[0010] The support rod is threadedly connected with the support.

[0011] The roller is made of rubber or silicone material with certain flexibility.

[0012] The utility model discloses a support is set up on the central shaft, and the support is set up with the parallel support pole of central shaft, and then the roller is set up on the support pole, and the outer side of the roller is abutted on the surface of arc driven roller and rotates with arc driven roller, so that the double-acting force mechanism effectively restrains the floating and deviation phenomenon of the fabric in the transmission process under the action of the outward supporting force provided by arc driven roller and the pressure provided by both sides rollers, thereby reducing the generation of fabric wrinkle.

[0013] Preferably, by the roller, the roller washer and the threaded connection of the support pole and the support of different outer diameter size, the control distance of the roller can be further changed according to the fabric width, ensuring that the fabric of different width can always move smoothly along the predetermined track in the transmission process, effectively avoiding the lifting phenomenon of the both sides of the cloth caused by uneven stress. Reduce the risk of low grammage fabric slipping, floating and winding in the transmission process, thereby improving the stability and reliability of the whole production process.

[0014] The utility model has the characteristics of simple structure, low cost, convenient use, good use effect and strong practicality, and is worth widely promoting and using. BRIEF DESCRIPTION OF DRAWINGS

[0018] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model. EMBODIMENT

[0019] Referring to Figs. 1-3 A kind of fabric is provided with 5g / m 2An arc-shaped driven roller assembly for preventing wrinkles in spunbond fabric composite spandex yarn elastic fabric includes a central shaft 1 and an arc-shaped driven roller 2 mounted on the central shaft 1. Supports 3 are respectively mounted on the outer sides of both ends of the arc-shaped driven roller 2 on the central shaft 1. Support rods 4 parallel to the central shaft 1 are mounted on the supports 3. The support rods 4 and supports 3 can be fixedly connected. In this embodiment, the support rods 4 are preferably threadedly connected to the supports 3, and locking nuts (not shown in the figure) are provided on both sides of the supports 3 on the support rods 4 to lock and fix them. Through the threaded connection, the extension length of the support rods 4 can be changed according to the fabric width, thereby controlling the pressing control distance of the rollers and ensuring that fabrics of different widths can always move smoothly along the predetermined track during transmission.

[0020] A roller 5 is mounted on the support rod 4 via a bearing 6. The inner side of the bearing 6 is interference-fitted with the support rod 4. In this embodiment, a roller washer 7 is provided between the inner side of the roller 5 and the bearing 6. The roller washer 7 has the same inner diameter and different outer diameters. Thus, when the extension length of the support rod 4 is changed according to the fabric width to control the pressing control distance of the roller, roller washers 7 with different outer diameters can be selected according to the distance between the support rod 4 and the surface of the arc-shaped driven roller 2, and the inner diameter can be matched with the roller. The roller 5 is adapted to the washer 7. At this time, the roller 5 can be a roller with the same difference between its inner and outer diameters but different inner and outer diameters, adapted to the roller washer 7 to adapt to the change in the distance between the support rod 4 and the surface of the arc-shaped driven roller 2. After assembly, the outer side of the roller 5 abuts against the surface of the arc-shaped driven roller 2 and rotates with the arc-shaped driven roller 2. Preferably, the roller is made of rubber or silicone material with a certain degree of flexibility, which can adapt to certain changes in fabric thickness and small adjustments in the extension length of the support rod 4, reducing the frequency of roller replacement.

[0021] In the above embodiments, the roller 5 can also be directly mounted on the bearing 6. The roller 5 includes multiple rollers with the same inner diameter and different outer diameters. By selecting rollers 5 with different outer diameters, the distance between the support rod 4 and the surface of the arc-shaped driven roller 2 can be changed when the extension length of the support rod 4 and the pressing control distance of the roller are changed. This allows the outer side of the roller 5 to abut against the surface of the arc-shaped driven roller 2 after assembly and rotate with the arc-shaped driven roller 2.

[0022] When using, please refer to Fig. 3 As shown, rollers 5 can be installed above, below, or even to the side of the curved driven roller 2. Depending on the contact position between the fabric 8 and the curved driven roller 2, the pressure provided by the rollers 5 on both sides is directed in the opposite direction to the support force provided by the curved driven roller 2. Under this dual force mechanism, the swaying and deviation of the fabric during transmission are effectively suppressed, ensuring that low-weight fabrics maintain good stability and reliability during transmission, thereby reducing fabric wrinkles. The effect is even better when multiple sets of the above-mentioned driven roller mechanisms are used in combination.

[0023] The above are some embodiments of the present application, but not the only ones. Any equivalent changes made according to the structure, shape, principle of the present application should be covered by the protection scope of the present application.
