Description

Technical Field

[0001] The utility model relates to the technical field of fabric processing, in particular to a fabric deviation correcting and feeding unit. Background Art

[0002] In the production process of fabrics and fabric products, the fabrics need to be fed, and rollers are needed in the feeding equipment. The fabrics are wound around the rollers and conveyed through the drive rollers of the rear station. Due to the soft nature of the fabrics, the fabrics need to be centered during the conveying process. If the fabrics are offset on both sides, the fabrics will fold during the conveying process, resulting in errors in the subsequent processes. The centering device is also called a deviation correction device. The existing equipment structure drives the fabric on it to correct the deviation to the left and right by the left and right displacement of the rollers, but the fabrics are prone to slip on the rollers, resulting in poor deviation correction accuracy. Utility Model Content

[0003] Based on this, it is necessary to provide a high-precision fabric correction and feeding unit to address the problem of low precision of the existing fabric correction unit.

[0004] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: a fabric deviation correction and feeding unit comprises a fixed base.

[0005] The swing frame can be moved left and right and is arranged on the upper end of the fixed base. The swing frame is provided with a plurality of rollers parallel to each other for conveying fabrics.

[0006] A track arranged along the displacement direction of the swing frame is fixedly provided on the fixed base, the swing frame is slidably installed on the track, a driving member is provided on the fixed base, and the swing frame reciprocates on the track through the driving member.

[0007] The left and right deviation of the fabric can be corrected by the overall displacement of the support frame.

[0008] In a preferred example, the utility model can be further configured as follows: the driving member includes a motor fixed above the fixed base, a base sleeve frame is fixedly provided at the bottom of the swing frame, the output end of the motor is transmission-connected with a screw rod, the screw rod is rotatably connected to the base sleeve frame through the forward and reverse rotation of the motor.

[0009] By adopting the above technical solution, the left-right deviation correction of the fabric can be achieved with a simple structure.

[0010] In a preferred example, the utility model can be further configured as follows: the rails are provided with two and are placed on both sides of the driving member, and a slider is fixedly provided at the bottom of the swing frame and slidably installed on the rails.

[0011] By adopting the above technical solution, the displacement effect of the bracket is improved and the correction accuracy is improved.

[0012] In a preferred example, the utility model can be further configured as follows: the roller shaft includes a rotatable main roller shaft and a fabric roller group, the main roller shaft and the fabric roller group are respectively arranged at the front and rear ends of the swing frame, and the main roller shaft has a larger diameter than the fabric roller.

[0013] By adopting the above technical solution, the main roller is used to store the wound fabric, and the fabric roller group is used to support the passing fabric.

[0014] In a preferred example, the utility model can be further configured as follows: the fabric roller group includes a first fabric roller, a second fabric roller and a third fabric roller, the second fabric roller is placed between the first fabric roller and the third fabric roller, and is positioned lower than the first fabric roller and the third fabric roller.

[0015] By adopting the above technical solution, the fabric passes over the first fabric roller, passes under the second fabric roller, and then passes over the third fabric roller, thereby realizing fabric transportation.

[0016] In a preferred example, the utility model can be further configured as follows: each of the fabric rollers is provided with a limiting ring for limiting the left and right positions of the fabric.

[0017] By adopting the above technical solution, the fabric can be prevented from slipping between the fabric roller and causing deviation during the conveying process.

[0018] In a preferred example, the utility model can be further configured as follows: limit sensors for monitoring the end positions of the two ends of the track are provided on both sides of the bottom of the swing frame.

[0019] By adopting the above technical solution, the swing frame can be prevented from falling off the track during the deviation correction process.

[0020] In summary, the utility model includes the following beneficial technical effects:

[0021] By correcting the deviation of the bracket supporting the fabric roller as a whole, a fabric limiting ring is provided to prevent the fabric from shifting when the fabric roller is corrected. The position of the fabric is fixed relative to the bracket, which prevents the fabric from shifting during the correction process and improves the correction accuracy.
