An intelligent take-up device for ultra-thin fabrics on a fine-gauge circular knitting machine

Abstract

The invention discloses an intelligent coiling device for fine-needle-pitch circular knitting machine ultrathin fabric. The intelligent coiling device comprises a servo motor, a main chain wheel, a first fabric clamping chain wheel, a second fabric clamping chain wheel, a fabric coiling chain wheel, a first fabric clamping rubber roller, a second fabric clamping rubber roller, a fabric coiling rubber roller, a fabric bolt roll size sensor and a controller. The main chain wheel drives the fabric coiling chain wheel to rotate through a second chain, an overload adjusting mechanism is arranged between the fabric coiling chain wheel and the fabric coiling rubber roller, and the fabric coiling rubber roller is parallel to the first fabric clamping rubber roller and the second fabric clamping rubber roller. The fabric bolt roll size sensor collects the sizes of fabric bolt rolls on the fabric coiling rubber roller and transmits size values to the controller, and then the controller adjusts the rotating speed of the servo motor. The coiling speed S of the fabric coiling rubber roller is equal to (the servo motor rotating speed N*the fabric bolt roll size change coefficient L)*(the main chain wheel tooth number T1 / the fabric coiling chain wheel tooth number T2)*the resistance coefficient 0.95. According to the intelligent coiling device, water ripples can be prevented from being generated on the fabric, and the selling quality of the fabric can be improved.

Description

technical field [0001] The invention relates to the field of circular knitting machines, in particular to an intelligent winding device for ultra-thin fabrics of fine-gauge circular knitting machines. Background technique [0002] The bottom of the circular knitting machine is usually equipped with a take-up device, which is used to wind the woven fabric to form a winding cloth. [0003] However, when the traditional winding device is suitable for ultra-thin fabrics formed with a fine gauge of more than 36 needles, such as fabrics formed of chemical fiber yarns such as 20D-30D nylon, the fabrics are relatively thin. Due to the problem of the winding force, the winding tension of the cloth surface is inconsistent, and it is easy to form water ripples, commonly known as chicken paw prints, which greatly reduces the quality of fabrics sold abroad and affects the market performance of the factory. [0004] After analysis, the main reasons for water ripples in high-quality fabri...

[0006] 2. At present, the cloth rolling rubber rollers are directly connected to the cloth rolling sprocket, that is, a direct rigid connection is adopted, and the cloth rolling sprocket is connected to the main sprocket through a chain, and the main sprocket is made of disc knitting. machine, while the circular knitting machine is driven by the motor to rotate, and then due to some instability of the power supply, there are some slight peak changes in the motor, these changes will eventually cause some unstable rotation of the cloth sprocket, and eventually cause damage to the sprocket. The pulling of the fabric, and then the water ripples on the fabric are formed by the uneven tension
