DETAILED DESCRIPTION

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] Referring to Figures (1-3), a knitted fabric straightening device includes a support frame 1 and two support columns 6, the support frame 1 is in the shape of a rectangular frame, and first slide grooves 11 are symmetrically provided on the front and rear sides of the frame, a movable plate 2 is slidably arranged between the two first slide grooves 11, one side of the movable plate 2 is provided with two grooves, and a first spring 21 is provided in the groove, a support rod 3 is slidably arranged in the groove, one end of the support rod 3 extends into the groove and is connected to one end of the first spring 21, and the other end is slidably connected to a support groove 12 provided on the support frame 1, one end of the first spring 21 is connected to the support rod 3, and the other end is connected to a pressure sensor provided at the bottom of the groove, a first roller 31 and a second roller 32 are rotatably arranged between the two support rods 3, and a placement groove 61 for placing the material rod 5 is provided on the top of the two support columns 6.

[0016] A screw 13 and a slide bar 14 are respectively provided on the two first slide grooves 11. The screw 13 is rotatably set in the first slide groove 11, passes through one end of the movable plate 2 and is screwed to the movable plate 2. The slide bar 14 passes through one end of the movable plate 2 and is slidably connected to the movable plate 2. A motor for driving the screw 13 to rotate is provided on the support frame 1.

[0017] The second roller shaft 32 is rotatably provided with connecting blocks at both ends, and the connecting blocks are penetrated by the support rod 3 and slidably connected with the support rod 3. The support rod 3 is sleeved with a second spring 33, and one end of the second spring 33 is connected to the connecting block, and the other end is connected to the outer wall of the support rod 3.

[0018] Two limiting rings 4 are slidably arranged on the material rod 5, and pressure plates 41 are slidably arranged on the two limiting rings 4. One end of the pressure plate 41 passes through the limiting ring 4, and the other end is rotatably connected to the top with an adjusting bolt 42. One end of the adjusting bolt 42 is connected to the pressure plate 41, and the other end passes through a fixing plate fixed on the limiting ring 4, and is screwed to the fixing plate. A fixing bolt 43 is screwed on the side of the limiting ring 4.

[0019] Rectangular slots 51 are provided at both ends of the material rod 5 , and a rotating rod 62 is slidably provided on one of the support columns 6 . One end of the rotating rod 62 can penetrate the support column 6 and can be inserted into the slot 51 of the material rod 5 placed on the placement slot 61 .

[0020] When the device is in use, the cloth passes through between the first roller 31 and the second roller 32. The second roller 32 squeezes the cloth passing through under the action of the second spring 33, and brings one end of the cloth to the material rod 5 to fit the outer wall of the material rod 5. The adjusting bolt 42 is rotated to drive the pressing plate 41 to press down and squeeze one end of the cloth. Then, the rotating rod 62 is inserted into the slot 51 of the material rod 5 to drive the material rod to rotate to reel in the cloth. When reeling in the cloth, the tension of the cloth will push the support rod 3 to move and squeeze the first spring 21 due to the tension being pulled. The first spring 21 transmits the squeezing force to the pressure sensor at the other end. The pressure sensor detects the squeezed force received to determine the tension of the cloth. According to the detected pressure, the motor connected to the screw 13 is controlled to drive the screw 13 to rotate, thereby driving the moving plate to move along the first slide groove 11 to adjust the tension received by the cloth. Tightening the fixing bolt 43 to squeeze it against the outer wall of the material rod can limit the movement of the limit ring on the material rod.
