[0002] Sweaters are widely used in daily clothing because of their soft, breathable and comfortable wearing experience. However, due to the structural characteristics of knitted fabrics, the fiber ends are easily broken and form pills due to friction during wearing or washing. The accumulation of pills not only affects the appearance of the clothes, but also may reduce the warmth retention and service life of the fabric.

[0003] After searching, the Chinese patent with the announcement number CN212925467U discloses a pilling removal device for textile apparel. The device does not require manual shearing of fabrics, has a high degree of automation, and is efficient, greatly reducing the time required for shearing fabrics and reducing labor costs. At the same time, the shearing effect is good, which indirectly improves the appearance of the fabrics. However, there are still the following problems: 1. When the device is removing pilling from clothing, the telescopic device is lowered to allow the shearing box to contact the surface of the fabric, thereby removing the pilling from the surface. However, when other parts of the clothing need to be removed, the telescopic device needs to be raised and the position of the clothing needs to be moved by the conveying device before the pilling operation is performed, which is time-consuming and greatly reduces the processing efficiency of the device; 2. When placing the clothing, the device simply places the clothing on the conveyor without fixing it, which is easy to shift during processing, thus affecting the effect of removing hair pills.
