[0032] A circular knitting machine cloth winding device with a novel cloth pressing assembly comprises a main frame 1, a knitting assembly 2 for knitting cloth located above the main frame 1, a cloth winding machine 3 is arranged below the knitting assembly 2, a plurality of rotating members 30 are circumferentially installed on the upper side of the cloth winding machine 3, a fixing member 31 is hinged at the top of the rotating member 30, and the other end of the fixing member is installed at the lower end of the knitting assembly 2, a replaceable cloth pressing assembly 4 is arranged between the knitting assembly 2 and the cloth winding machine 3, and the replaceable cloth pressing assembly 4 is detachably mounted on a fixing seat 5, and the fixing seat 5 is mounted on the fixing member 31. In some embodiments, the fixing member 31 is arranged as a fixing rod, and a fixing plate for mounting the fixing seat 5 is arranged on the fixing rod.

[0033] A supporting mechanism 20 is installed in the middle of the lower end of the knitting assembly 2, and a plurality of cloth winding drums 21 are arranged along the circumferential direction of the supporting mechanism 20. The cloth winding drums 21 are arranged below the replaceable cloth pressing component 4 and on the upper side of the cloth winding machine 3. The number of cloth winding drums 21 corresponds to the replaceable cloth pressing component 4. The knitted grey cloth 6 woven by the knitting assembly 2 passes through the replaceable cloth pressing component 4 and the cloth winding drums 21 in sequence and then enters the cloth winding machine 3, which helps to reduce the shaking amplitude of the knitted grey cloth 6 and improve the flatness of the cloth surface.

[0034] In some embodiments, the replaceable cloth pressing assembly 4 and the cloth rolling machine 3 are oriented in opposite directions in the horizontal direction, and the distance between the replaceable cloth pressing assembly 4 and the straight line where the center of the knitting assembly 2 is located is smaller than the distance between the cloth rolling drum 21 and the straight line where the center of the knitting assembly 2 is located, so that the knitted grey cloth 6 woven by the knitting assembly 2 is subjected to bidirectional cloth stretching under the action of the replaceable cloth pressing assembly 4 and the cloth rolling drum 21 before entering the cloth rolling machine 3, which is beneficial to reduce the pulling phenomenon of the knitted grey cloth 6 caused by uneven tension, so as to achieve a better cloth stretching effect and improve the flatness of the cloth surface.

[0035] In some embodiments, the fixed seat 5 includes a base 50 and a locking assembly. The base 50 is provided with a long arc groove 51 and a through hole 52. The replaceable cloth pressing assembly 4 is provided with a mounting hole relative to the long arc groove 51 and the through hole 52. The mounting hole locks the replaceable cloth pressing assembly 4 on the long arc groove 51 and the through hole 52 of the fixed seat 5 through the locking assembly. The long arc groove 51 can adjust the inclination angle of the replaceable cloth pressing assembly 4, thereby adjusting the pressing force of the replaceable cloth pressing assembly 4 on the knitted grey cloth 6.

[0036] In some embodiments, the replaceable cloth pressing assembly 4 includes a connecting rod 40, a mounting hole is provided on the connecting rod 40, a cloth pressing device is detachably mounted on the connecting rod 40, and the cloth pressing device is arranged as an outward arc structure, which is formed into an arc shape to increase the contact with the cloth surface, reduce the deformation of the cloth surface caused by excessive squeezing, better protect the cloth surface, make it within the elastic range of the coil, and restore the coil shape, so that the cloth surface is smoother. As an example, see Figure 2 , the cloth pressing device is configured as an arc-shaped curved rod 41 facing outward; as an example, see Figure 3 The cloth pressing device includes a first fixed frame 420, on which an arc-shaped outer arc roller rod 421 facing outward is installed. During the production process of the existing large circular knitting machine, the surface of the knitted grey cloth 6 rotates continuously, and the internal high temperature generates oil mist. Or due to the machine washing and cleaning, the knitting oil may not be partially cleaned up. Or due to improper operation or aging of the machine seal, etc., there are often oil drops hanging on the traditional cloth pressing rod, and oil drops often fall into the grey cloth. After the knitted oil droplets soak the cloth surface, it is difficult to remove them later, which affects the product quality. The outer arc roller rod 421 is used to support the cloth surface. While the arc-shaped structure increases the contact area, the outer arc roller rod 421 rolls with the cloth surface to prevent oil mist from hanging on the outer arc roller rod 421, thereby preventing the knitted grey cloth 6 from being soaked by oil droplets, which is beneficial to ensure product quality. In some other embodiments, see Figure 4 The replaceable cloth pressing assembly 4 includes a connecting rod 40, one end of which is mounted with a second fixing frame 430, and a columnar roller rod 431 is mounted on the second fixing frame 430. The columnar roller rod 431 rolls with the cloth surface to prevent oil mist from dripping on the columnar roller rod 431, thereby preventing the knitted grey cloth 6 from being stained by oil droplets.

[0037] The description of the above specification and embodiments is used to explain the protection scope of the utility model, but does not constitute a limitation on the protection scope of the utility model. Through the enlightenment of the utility model or the above embodiments, ordinary technicians in this field can obtain modifications, equivalent replacements or other improvements to the embodiments of the utility model or part of the technical features thereof through logical analysis, reasoning or limited experiments, which should be included in the protection scope of the utility model.
