Figure 2 DETAILED DESCRIPTION In order to make the purpose, technical content, construction features, realized purposes and effects of the utility model clearer, the following will be described in detail in combination with the embodiment and the drawings.

[0023] The embodiment discloses a winding cloth conveying device, which is used in cooperation with a processing platform 1 to gradually release the cloth in the cloth roll onto the processing platform 1 to meet the processing progress of the processing platform 1 on the cloth.

[0024] Figures 1 to 4 The conveying device comprises a base 2 arranged at the feeding end of the processing platform 1, the base 2 is provided with a trough 20 for placing the cloth roll, and the trough 20 is provided with a rolling mechanism, the rolling mechanism is used for driving the cloth roll to rotate to release the cloth on the cloth roll.

[0025] The base 2 and the feeding end of the processing platform 1 are further provided with a tension rod 21 and a guide rod 10, the cloth output from the cloth roll is wound from the bottom of the tension rod 21 to the top of the guide rod 10, and then enters the feeding end of the processing platform 1 downward through the top of the guide rod 10.

[0026] The base 2 and the feeding end of the processing platform 1 are further provided with a tension rod 21 and a guide rod 10, the cloth output from the cloth roll is wound from the bottom of the tension rod 21 to the top of the guide rod 10, and then enters the feeding end of the processing platform 1 downward through the top of the guide rod 10. ​​​

[0027] The tension rod 21 can swing back and forth between the base 2 and the processing platform 1 under the stretching force of the cloth. The guide rod 10 is in an arc structure and arches upward.

[0028] In this embodiment, first, the tension rod 21 can swing back and forth under the stretching force of the cloth, forming a passive tension feedback system. When the cloth release speed does not match the processing platform 1 traction speed, the tension rod 21 automatically compensates for the tension fluctuation by changing the swing amplitude. For example, when the cloth is too loose, the tension rod 21 moves backward to increase the wrap angle and increase the tension. When it is too tight, it moves forward to reduce the wrap angle and relieve the stretch. Through the tension rod 21, without complex sensors or active driving, continuous and flexible tension balance can be achieved, effectively avoiding the problem of cloth tearing or accumulation caused by rigid constraints of traditional fixed guide rollers.

[0029] Secondly, the guide rod 10 adopts an arc structure that arches upward, and the cloth transitions from the bottom of the tension rod 21 to the top of the guide rod 10, forming an "S" shaped bending path. The contact surface between the arc-shaped guide rod 10 and the cloth is gradually expanded, and the lateral friction force is uniform, which can inhibit the cloth from deviating. Moreover, the cloth is subjected to radial tension at the arched top, naturally flattening the wrinkles, especially for elastic or lightweight fabrics (such as chiffon, spandex). In addition, the arc bending replaces the traditional right-angle turning, increases the effective bending radius, reduces the local tensile stress, and avoids material damage.

[0030] Thirdly, the rolling mechanism actively drives the cloth roll to rotate and release, combined with the swing adjustment of the tension rod 21, forming a "active unwinding + passive tension adjustment" double-stage control. The rolling mechanism can dynamically adjust the unwinding speed according to the traction speed of the processing platform 1, reducing manual intervention. The swing of the tension rod 21 can absorb the instantaneous speed difference of the cloth roll due to inertia, preventing the cloth from loosening or breaking when unwinding at high speed.

[0031] On the other hand, as Figure 3 The guide rod 10 is arranged above the feeding end of the processing platform 1 to effectively ensure the flattening effect of the guide rod 10 on the cloth entering the processing platform 1.

[0032] On the other hand, as Figure 2 The trough 20 is in a V-shaped structure that is narrow at the bottom and wide at the top, and can accommodate cloth rolls of different sizes and diameters.

[0033] Further, the rolling mechanism includes a first roller M1 and a second roller M2 arranged on one side of the trough 20, and a third roller M3 and a fourth roller M4 arranged on the other side of the trough 20.

[0034] The first roller M1 and the third roller M3 are located at the bottom of the trough 20, and the second roller M2 and the fourth roller M4 are located at the top of the trough 20.

[0035] The first transmission belt P1 is sleeved between the first roller M1 and the second roller M2, and the second transmission belt P2 is sleeved between the third roller M3 and the fourth roller M4.

[0036] The first transmission belt P1 and the second transmission belt P2 are respectively used to drive the two sides of the cloth roll to rotate. Specifically, the first transmission belt P1 and the second transmission belt P2 provide opposite rotating forces for the opposite sides of the cloth roll, so that the cloth roll rotates to release the cloth.

[0037] Further, a plurality of first transmission belts P1 are sleeved between the first roller M1 and the second roller M2, and a plurality of second transmission belts P2 are sleeved between the third roller M3 and the fourth roller M4. In the embodiment, the transmission belts are arranged in sections, which is convenient for installation and saves materials.

[0038] On the other hand, the second roller M2 is located at one side of the trough 20 close to the processing platform 1, and a fifth roller M5 is further arranged above the second roller M2. The second roller M2 and the fifth roller M5 have a gap J0 therebetween, and the cloth output from the cloth roll passes through the gap J0. In the embodiment, the gap J0 between the second roller M2 and the fifth roller M5 is used as an output port of the cloth. By adjusting the size of the gap J0, the cloth can pass through the gap J0 with interference, thereby achieving the effect of smoothing the cloth.

[0039] On the other hand, the tension rod 21 is arranged below the second roller M2. In this way, the free end of the cloth is guided downward to the tension rod 21 after coming out of the gap J0, and then guided upward from below the tension rod 21 to the guide rod 10, thereby lengthening the running path of the cloth and increasing the control effect on the cloth feeding.

[0040] On the other hand, the trough 20 is provided with a guard plate 22 at each end thereof, and the first roller M1, the second roller M2, the third roller M3, the fourth roller M4 and the fifth roller M5 are respectively pivotally connected to the two guard plates 22. The guard plate 22 in the embodiment has a V-shaped structure.

[0041] In addition, as Figure 2 the two ends of the tension rod 21 are pivotally connected to the guard plate 22 through a rotating support 23, and the guard plate 22 is further provided with an elastic member 24 connected to the rotating support 23. The elastic member 24 is used to provide an elastic restoring force for the rotating support 23 to restore to a vertical position.

[0042] In the embodiment, when the consumption speed of the cloth on the processing platform 1 is greater than the feeding speed of the cloth, the tension of the cloth becomes larger, the cloth pulls the tension rod 21 to swing in the direction of the processing platform 1, the elastic member 24 is elongated, and the elastic restoring force is generated. When the tension of the cloth is restored, the rotating support 23 drives the tension rod 21 to automatically reset under the action of the elastic restoring force.

[0043] On the other hand, the side close to the fourth roller M4 between the two guards 22 is also provided with a support column 25, and the upper two ends of the trough 20 are also provided with two baffles 260, which are slidably connected with the support column 25 through connecting rods 261, so that the baffles 260 can slide horizontally along the trough 20, and the baffles 260 are used to block the horizontal movement of the cloth roll. In this embodiment, during feeding, the two connecting rods 261 are pushed to slide along the support column 25 in opposite directions, so that the two baffles 260 slide out of the feeding area. When the cloth roll is placed in the trough 20, the two connecting rods 261 are pushed to slide along the support column 25 in opposite directions again, so as to block the two ends of the cloth roll, avoiding horizontal movement of the cloth roll during rotation.

[0044] The above only discloses preferred embodiments of the utility model, of course, cannot limit the scope of the utility model right with this, therefore the equivalent change made in the utility model application patent range, still belongs to the range covered by the utility model.
