[0033] like Figures 1 to 4 As shown, a drying device for spandex fabric before winding includes a drying rack 1, and the drying device for spandex fabric before winding also includes:

[0034] Drying component 2 is installed on drying rack 1 and is used to convey and dry spandex fabric.

[0035] The flattening part 4 is arranged on the drying rack 1 and is used to flatten the spandex fabric before drying. The spandex fabric is first passed through the inside of the flattening part 4 and then wound on the drying piece 2. In this way, the spandex fabric is first flattened and then dried.

[0036] The flattening part 4 comprises a support frame 41 fixedly arranged on the drying rack 1.

[0037] The horizontal support frame 42 is vertically slidably arranged in the inside of the support frame 41.

[0038] The two fabric pulling rollers 44 are oppositely rotatably arranged on the horizontal support frame 42.

[0039] The support plate 46 is transversely fixedly arranged in the inside of the support frame 41, and the two fabric pulling rollers 44 press the spandex fabric on the support plate 46.

[0040] The servo motors 45 are used to drive the rotation of the fabric pulling rollers 44. The rotation directions of the opposite surfaces of the two fabric pulling rollers 44 are both from top to bottom, and the spacing between the two fabric pulling rollers 44 is smaller than the width of the spandex fabric. The two servo motors 45 drive the opposite rotation of the two fabric pulling rollers 44 and flatten the spandex fabric passing through the bottom of the fabric pulling rollers 44. In this way, the spandex fabric is subjected to two opposite friction forces in the width direction, and the two friction forces are both in the direction away from each other.

[0041] As shown in Figure 3 and Figure 4 The flattening part 4 further comprises the elastic member 43 arranged between the horizontal support frame 42 and the support frame 41, and the elastic member 43 is used to provide a vertical movement space for the fabric pulling rollers 44.

[0042] The elastic member 43 comprises the guide rod 431 oppositely fixedly arranged on the top of the horizontal support frame 42 and the spring 432 slidably sleeved on the outside of the guide rod 431, and the top end of the guide rod 431 is slidably sleeved on the top of the support frame 41.

[0043] The two ends of the spring 432 respectively abut against the top inside the support frame 41 and the top of the horizontal support frame 42.

[0044] When the wrinkle of the spandex fabric enters between the fabric pulling rollers 44 and the support plate 46, the fabric pulling rollers 44 are moved upward under the action of the wrinkle and are always subjected to sufficient pressure between the fabric pulling rollers 44 and the surface of the spandex fabric under the action of the elastic force of the spring 432, so that sufficient friction force in the horizontal direction between the fabric pulling rollers 44 and the spandex fabric is provided to flatten the spandex fabric.

[0045] As shown in Figure 2 and Figure 3As shown, the drying piece 2 includes a drying roller 21 rotatably arranged inside the drying frame 1, the spandex cloth is wound outside the drying roller 21, and the spandex cloth is completely attached to three-quarters of the area outside the drying roller 21. The outside of the drying roller 21 is uniformly provided with a plurality of air holes 23.

[0046] A driving motor 22 is used to drive the low-speed rotation of the drying roller 21. By driving the drying roller 21 to rotate at a low speed, the spandex cloth has enough time to be dried, and the cloth pulling roller 44 has enough time to pull the spandex cloth flat, avoiding missing and affecting the appearance and quality of the spandex cloth, and conveying to the next winding process after drying.

[0047] A heating rod 24 is arranged axially inside the drying roller 21. The heating rod 24 is used to heat the air inside the drying roller 21. The heated air exchanges heat with the spandex cloth through the air holes 23 between the spandex cloth, and the heat evaporates the moisture on the spandex cloth, and the high-temperature air dries the spandex cloth wound outside the drying roller 21.

[0048] As shown in Figure 1 and Figure 3 As shown, the drying equipment before the spandex cloth is wound also includes a guide roller 3 fixedly arranged at the top of the drying frame 1. The guide roller 3 is used to tighten and flatten the spandex cloth between the flattening part 4 and the drying roller 21.

[0049] The top of the guide roller 3 is flush with the top of the support plate 46, and the bottom of the guide roller 3 is higher than the top of the drying roller 21. The conveying direction of the spandex cloth can be changed by the guide roller 3, so that the spandex cloth passes through the top of the guide roller 3 and the drying roller 21 horizontally, then winds down to the bottom of the drying roller 21, and finally passes from the horizontal radial direction of the drying roller 21 to the next process, and the conveying direction is parallel and opposite to the direction into the bottom of the cloth pulling roller 44. The contact area of the spandex cloth with the drying roller 21 is maximized, the spandex cloth is subjected to two opposite friction forces in the width direction, and the two friction forces are in the direction away from each other. In this way, the spandex cloth can be pulled flat to avoid wrinkles when the spandex cloth contacts the drying roller 21.

[0050] Working principle: first, the spandex cloth is passed between the bottom of the cloth pulling roller 44 and the top of the supporting plate 46, and then the conveying direction of the spandex cloth is changed through the guide roller 3, so that the spandex cloth passes horizontally through the top of the guide roller 3 and the drying roller 21, and then winds downward to the bottom of the drying roller 21, and finally passes horizontally from the drying roller 21 to the next process, and the conveying direction is parallel and opposite to the direction into the bottom of the cloth pulling roller 44, which maximizes the contact area of the spandex cloth with the drying roller 21, and the servo motor 45 is started before the spandex cloth is conveyed, so that the two cloth pulling rollers 44 rotate in opposite directions, so that the rotating direction of the opposite surfaces of the two cloth pulling rollers 44 is from top to bottom, so that the spandex cloth can be pulled flat, and finally the drying roller 21 is driven to rotate at low speed, so that the spandex cloth has enough time to be dried, and the cloth pulling roller 44 has enough time to pull the spandex cloth flat, avoiding missing and affecting the appearance and quality of the spandex cloth, and conveying to the next winding process after drying, avoiding wrinkles during drying and winding, affecting the appearance and quality of the spandex cloth.
