[0002] The fabric loosening machine is a device used for finishing, rolling, measuring, loosening and folding fabric. After purchasing the rolls of fabric normally, the fabric needs to be loosened before cutting to restore it to its original state. If it is not loosened, the size, quality and production efficiency of the finished garment will be affected.

[0003] The Chinese patent provides a cloth loosening machine, with the publication number CN220578530U, which includes a frame, on which a reeling mechanism and a reeling mechanism are respectively provided, the reeling mechanism includes a mounting seat that slides with the frame, the mounting seat is provided with a mounting rod fixedly connected thereto, the mounting rod is provided with a centering electric eye fixedly mounted thereto for sensing the side edge of the cloth, the mounting seat is provided with a driving assembly that is transmission-connected thereto for driving the mounting seat to slide, and the driving assembly includes an electric cylinder fixedly mounted on the frame.

[0004] The above-mentioned cloth loosening machine has the effect of avoiding indentations and wrinkles on the sides of the cloth rolls when they are stored. However, during the cloth loosening process, since the tightness of the cloth rolls is different, the cloth is easily stretched too tight or too loose during the cloth loosening process, which is not convenient for adaptive stretching of the cloth. At the same time, different cloths are stretched to different tightnesses, which is not convenient for adjusting the tightness. Therefore, it is necessary to provide a cloth loosening machine with adjustable tension. Utility Model Content

[0023] Embodiment 1

[0024] Combined with Figures 1 - 4 , a cloth loosening machine with adjustable tension includes two chassis 1, two rollers 2 are movably installed between the two chassis 1, a support mechanism 3 is installed at the bottom of the two chassis 1, and an adjusting mechanism 4 is installed at the front of the two chassis 1.

[0025] Referring to Figure 2 and Figure 3 , it is further obtained that the support mechanism 3 includes a pressure roller 5 and two fixed seats 6. The pressure roller 5 is movably installed between the two chassis 1 near the front end. The two fixed seats 6 are respectively fixedly installed at the front of the two chassis 1. Two guide rods 7 are fixedly installed inside the fixed seat 6. Shaft blocks 8 are movably installed outside the two guide rods 7. Springs 10 are sleeved around the guide rods 7. A support rod 9 is movably installed between the two shaft blocks 8.

[0026] The two rollers 2 are driven by a motor in the chassis 1, and both ends of the pressure roller 5 are in contact with the roller 2 at the front end.

[0027] The shaft block 8 is sleeved outside the guide rod 7 and is arranged in a sliding manner. The support rod 9 is located between the two shaft blocks 8 and is arranged in a rotatable manner.

[0028] The support rod 9 and the central axis of the roller 2 are located in the same horizontal plane, and the spring 10 is located behind the shaft block 8.

[0029] Specifically, by placing the fabric roll between the two rollers 2, then stretching the fabric roll to the outside of the support rod 9 and threading it between the roller 2 at the front end and the pressure roller 5, the two rollers 2 are driven to rotate by a motor in the chassis 1, and through the reciprocating swing of the guide plate, the fabric is loosened. The shaft blocks 8 at both ends of the support rod 9 slide adaptively under the action of the spring 10 to support the fabric.

[0030] Embodiment 2

[0031] Refer to Figure 4 and on the basis of Embodiment 1, it is further obtained that the adjusting mechanism 4 includes two screw rods 11 and a rotating rod 13. The two screw rods 11 are respectively movably installed inside the two fixed seats 6. A pressing plate 12 is movably installed outside the screw rods 11 and the two guide rods 7. The rotating rod 13 is movably installed between the two fixed seats 6. Bevel gears 14 are installed at both ends of the periphery of the rotating rod 13 and at the front end of the screw rod 11. A rocking disc 15 is installed at one end of the rotating rod 13.

[0032] The pressing plate 12 is arranged in a threaded connection with the screw rod 11. A through groove is provided at the center of the front and rear parts of the through shaft block 8. The cross-sectional diameter of the screw rod 11 is smaller than the inner diameter of the through groove.

[0033] The rotating rod 13 is movably rotated between the two fixed seats 6. The bevel gears 14 at both ends of the periphery of the rotating rod 13 are in meshing connection with the bevel gears 14 at the front end of the screw rod 11.

[0034] Specifically, by shaking the rocking disc 15, through the meshing of the bevel gears 14, the rotating rod 13 drives the two screw rods 11 to rotate, and the screw rods 11 drive the pressing plate 12 to slide, so that the pressing plate 12 slides back and forth, changing the elastic force of the spring 10, which is convenient for adjusting the tightness of the fabric stretched by the support rod 9.

[0035] In the actual operation process, the fabric roll is placed on the two rotating rollers 2. The two rotating rollers 2 are driven by the motor in the chassis 1 to rotate, so that the fabric roll rotates to stretch out the fabric, and the stretched and relaxed fabric is stacked by the reciprocating swing of the guide plate;

[0036] When loosening the fabric, the fabric is stretched onto the support rod 9 and inserted between the front rotating roller 2 and the pressure roller 5. During the rotation of the rotating roller 2, the pressure roller 5 is driven to rotate under the action of friction, thereby enhancing the stretching and conveying of the fabric. The shaft blocks 8 at both ends of the support rod 9 automatically slide forward under the action of the spring 10 to stretch and support the fabric. The support rod 9 slides adaptively through the spring 10, enabling the fabric to be in a stretched state;

[0037] When adjusting the stretching and relaxation degree, by shaking the rocking disc 15, under the meshing action of the bevel gears 14, the two screw rods 11 are driven to rotate simultaneously by the rotating rod 13. The pressing plate 12 slides forward under the thread action of the screw rod 11, causing the spring 10 to contract, increasing the elastic force of the spring 10, and further increasing the stretching of the fabric by the support rod 9, improving the relaxation degree of the fabric.

[0038] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to the embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
