[0021] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In a preferred embodiment, the curling smoothing component 7 includes: a sliding fixed plate 702, a circular hole is opened on the sliding fixed plate 702, and an electric telescopic rod 703 is fixedly connected to the inside of the circular hole; a smoothing roller 706, the outer side of the smoothing roller 706 is in contact with the reverse side of the knitted cloth 6, and both sides of the smoothing roller 706 are movably connected to a fixed frame 705, and one side of the fixed frame 705 is fixedly connected to the front end of the electric telescopic rod 703; an ironing machine 708, and the ironed side of the ironing machine 708 is in contact with the reverse side of the knitted cloth 6.

[0022] In this solution, the curling and smoothing component 7 also includes: a connecting member 701, which is fixedly connected to the inner side of the fixed plate 5, and the bottom end of the connecting member 701 is fixedly connected to the top of the sliding fixed plate 702; two sliding rods 704, which are both fixedly connected to one side of the fixed frame 705, and the sliding fixed plate 702 has two through-holes, and the sliding rods 704 are both slidably connected inside the through-holes; a base frame 707, which is fixedly connected to the inner side of the fixed plate 5, and the top end of the base frame 707 is fixedly connected to the bottom end of the ironing machine 708.

[0023] The curling smoothing component 7 uses the rolling extrusion of the smoothing roller 706 and the ironing of the ironing machine 708 to initially smooth the edge using pressure and friction, and then the ironing machine 708 further smoothes it with the help of heat and pressure. The step-by-step process makes the curling edge go from initial shaping to deep flattening, which can effectively improve the curling condition of the knitted fabric 6 and enhance the flatness and appearance quality.

[0024] Reference Figure 3 and Figure 5In a preferred embodiment, the adaptive anti-curling component 12 includes: a motor frame 1202, a bidirectional motor 1203 is fixedly connected to the inner side of the motor frame 1202, and the two power output shafts of the bidirectional motor 1203 are respectively connected to a threaded rod 1205 through a coupling, and the ends of the two threaded rods 1205 away from the bidirectional motor 1203 are respectively fixedly connected to the two sides of the fixed plate 5; a plurality of anti-curling rollers 1204 are symmetrically distributed on the front and back sides of the knitted cloth 6, the anti-curling rollers 1204 are in contact with the front and back sides of the knitted cloth 6, and the interior of the anti-curling rollers 1204 are movably connected to a fixed rod 1207.

[0025] In this solution, the adaptive anti-curling component 12 also includes: a connecting rod 1201, which is fixedly connected to the inner sides of the fixed plate 5, and the outer side of the connecting rod 1201 is fixedly connected to the inner side of the top of the motor frame 1202; two sliding members 1206, both of which are movably connected to the outer side of the connecting rod 1201; two connecting frames 1208, both of which are fixedly connected to the front end of the sliding member 1206, the outer side of the threaded rod 1205 is movably connected to the rear side of the connecting frame 1208, and both ends of the fixed rod 1207 are fixedly connected to the inner sides of the connecting frame 1208; the multiple anti-curling rollers 1204 of the adaptive anti-curling component 12 are symmetrically distributed on the front and back sides of the knitted cloth 6. The friction and pressure generated by rolling can directly and effectively prevent the knitted cloth 6 from curling on both sides after the cloth is pulled, thereby ensuring that the edges of the knitted cloth 6 are flat and improving product quality.

[0026] Reference Figure 1-Figure 3 In a preferred embodiment, both sides of the top of the cloth-pulling body 1 are fixedly connected to fixed seats 3, and the rotating roller 9 is rotatably connected to the opposite side of the two fixed seats 3. Both sides of the top of the cloth-pulling body 1 are fixedly connected to connecting seats 8, and the opposite sides of the connecting seats 8 are fixedly connected to both sides of the ironing machine 4. An auxiliary roller 11 is also movably connected between the two fixed plates 5. The auxiliary roller 11 is arranged between the cloth-pulling roller 10 and the adaptive anti-curling component 12, and the outer side of the auxiliary roller 11 is in contact with one side of the knitted cloth 6.

[0027] Working principle: When in use, the knitted fabric 6 is wound around the rotating roller 9, which is supported by the fixed seat 3 and is in a state of waiting to be pulled; the knitted fabric 6 is drawn out from the rotating roller 9, and the electric telescopic rod 703 is started. When the electric telescopic rod 703 is extended or shortened, it drives the fixed frame 705 to move. When the fixed frame 705 moves, it drives the smoothing roller 706 to move. The outer side of the smoothing roller 706 contacts the knitted fabric 6. Driven by the fixed frame 705, the smoothing roller 706 rolls repeatedly on the knitted fabric 6, and the knitted fabric 6 is smoothed by the pressure and friction generated by the rolling of the roller. The curling edges on both sides are initially smoothed, and the sliding rod 704 slides in the perforations of the sliding fixed plate 702, guiding and stabilizing the movement of the fixed frame 705, ensuring that the smoothing roller 706 moves smoothly. After the smoothing roller 706 is initially smoothed, the ironing machine 708 irons the reverse side of the knitted fabric 6. The ironing machine 708 further smoothes the knitted fabric 6 through heat and pressure, so that the curling edges preliminarily processed by the smoothing roller 706 are better smoothed, completing the smoothing of the curling edges on both sides of the knitted fabric 6; the knitted fabric 6 that has been smoothed by the curling edges reaches the cloth pulling roller 10, the cloth-pulling roller 10 rotates to pull the knitted fabric 6 from the rotating roller 9 to unfold it. During this process, the auxiliary roller 11 plays the role of auxiliary support and guidance of the knitted fabric 6 to ensure a smooth cloth-pulling process; the bidirectional motor 1203 starts to drive the threaded rod 1205 to rotate, and the rotating threaded rod 1205 causes the connecting frame 1208 to move along the axial direction of the threaded rod 1205. When the connecting frame 1208 moves, the sliding member 1206 slides along the connecting rod 1201 to guide and stabilize the movement of the connecting frame 1208, ensuring its smooth movement. There is no deviation. When the connecting frame 1208 moves, it will drive the fixed rod 1207 and the anti-roll roller 1204 to move, so that the anti-roll roller 1204 is always in contact with the front and back sides of the knitted cloth 6. The anti-roll roller 1204 contacts and rolls with the knitted cloth 6. The friction and pressure generated by the rolling prevent the knitted cloth 6 from curling on both sides, thereby realizing the anti-curling function after the cloth is pulled; the knitted cloth 6 that has been treated with anti-curling reaches the ironing machine 4, and the ironing machine 4 irons the knitted cloth 6 to further improve the flatness and appearance quality of the knitted cloth 6, thereby completing the entire cloth pulling and processing process.

The replacements described may be partial structures, devices, or method steps, or they may be complete technical solutions. Any equivalent replacements or modifications based on the technical solution and the concept of the present invention shall be covered by the scope of protection of the present invention.
