[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-4 A fabric turning mechanism for producing curtain fabric includes a processing table 1, on which a motor 2 is fixedly installed, and the output end of the motor 2 is fixedly connected to a rotating shaft 3. A fixed frame 4 is fixedly installed on the rotating shaft 3, and a movable frame 5 for unfolding the fabric is connected to the fixed frame 4 through a lifting component. The rotating shaft 3 is vertically arranged, and the fixed frame 4 and the movable frame 5 have a concave structure.

[0023] The lifting component includes a second motor 6 fixedly installed in a fixed frame 4, and a double-acting lead screw 7 fixedly connected to the output end of the second motor 6. A second double-acting lead screw 8, which is driven by the first double-acting lead screw 7, is rotatably installed in the fixed frame 4. Matching nuts 9 are slidably sleeved on the first double-acting lead screw 7 and the second double-acting lead screw 8. The nuts 9 are mounted on a movable frame 5. The first double-acting lead screw 7 and the second double-acting lead screw 8 are vertically arranged, and a transmission belt 23 is connected between the first double-acting lead screw 7 and the second double-acting lead screw 8 through a coupling. The transmission belt 23 is preferably a synchronous belt, which has the advantages of compact structure and non-slippage, so that the first double-acting lead screw 7 and the second double-acting lead screw 8 can be driven at the same speed.

[0024] When the curtain fabric needs to be unfolded, the second motor 6 is powered on, and the double-acting screw 7 and the second double-acting screw 8 are rotated through the transmission belt 23. When the nut 9 moves upward, it drives the moving frame 5 to move upward. After the moving frame 5 moves upward, it can adjust the distance between the fixed frame 4 and the moving frame 5, thereby unfolding the curtain fabric so that the fabric will not wrinkle when unfolded.

[0025] The fixed frame 4 and the movable frame 5 are equipped with clamping structures for clamping the fabric.

[0026] The clamping structure includes a frame 10 placed within a fixed frame 4 and a movable frame 5, with a support plate 11 movably installed inside the frame 10. A clamping plate 12 for clamping the fabric is installed on the support plate 11. A spring 13 is welded between the frame 10 and the support plate 11. By adjusting the distance between the two frames 10, the two frames 10 can clamp fabrics of different widths. Under the action of the spring 13, the clamping plate 12 can clamp the four corners of the fabric. A vertical plate 20 is fixedly installed on the frame 10, and a pressing plate 21 for pressing the fabric is slidably fitted inside the vertical plate 20. A spring 22 is welded between the pressing plate 21 and the vertical plate 20. Under the action of the spring 22, the pressing plate 21 can clamp the side wall of the fabric, so that the fabric will not wrinkle after unfolding.

[0027] A movable rod 14 is slidably sleeved inside the fixed frame 4 and the movable frame 5. A support block 15 and a pressure plate 16 for clamping the middle of the fabric are fixedly installed on the movable rod 14. A spring 17 that cooperates with the movable rod 14 is welded between the pressure plate 16 and the fixed frame 4 and the movable frame 5. The fixed frame 4 and the movable frame 5 guide the movable rod 14 so that the movable rod 14 can smoothly pull the support block 15 and the pressure plate 16 when it moves. Under the action of the spring 17, the pressure plate 16 can clamp the middle of the fabric.

[0028] The frame 10 and the upright plate 20 are concave structures. The frame 10 is fixedly installed with connecting ears, and the connecting ears are threaded with fixing bolts that are connected to the frame 10. The moving rod 14 is horizontally set on both sides of the fixed frame 4 and the moving frame 5. The support block 15 and the moving rod 14 extend to one side outside the fixed frame 4 and the moving frame 5.

[0029] Spring 17 is sleeved on the moving rod 14. A support plate 18 is placed inside the fixed frame 4 and the moving frame 5. A self-locking shaft is fixedly installed on the fixed frame 4 and the moving frame 5, and an intercepting plate 19 is provided on the self-locking shaft to clamp the support plate 18. The support plate 18 is vertically set outside the pressure plate 16. By placing the support plate 18 between the fixed frame 4 and the pressure plate 16, and between the moving frame 5 and the pressure plate 16, and by limiting the support plate 18 through the intercepting plate 19, the stability of the support plate 18 and the pressure plate 16 can be ensured.

[0030] The functional principle of this utility model can be explained through the following operation methods:

[0031] Extend the lower end of the fabric to the fixing frame 4, adjust the spacing between the two frames 10 according to the width of the fabric, and use fixing bolts to connect the connecting ears to the frames 10.

[0032] The two ends of the fabric extend into the frame 10 inside the fixed frame 4, and the support block 15 is pulled out, so that the support block 15 drives the moving rod 14 to slide in the fixed frame 4 and the moving frame 5, the spring 3 17 is stressed, and the middle end of the fabric is placed between the two pressure plates 16.

[0033] Press the pressing plate 21 and place the fabric between the two pressing plates 21. The spring 22 is stressed and releases the pressure on the pressing plate 21. The pressing plate 21 clamps the fabric from both sides.

[0034] Through the above steps, the fixed frame 4 can clamp the lower end of the fabric, and the movable frame 5 can clamp the upper end of the fabric.

[0035] The output end of motor 26 drives the bidirectional lead screw 1 7 to rotate. When bidirectional lead screw 1 7 rotates, it drives bidirectional lead screw 2 8 to rotate through transmission belt 23. When bidirectional lead screw 1 7 and bidirectional lead screw 2 8 rotate, they drive nut 9 to move upward. When nut 9 moves upward, it drives moving frame 5 to move upward. When moving frame 5 moves upward, it unfolds the fabric.

[0036] The output of motor 2 drives the rotating shaft 3 to rotate. When the fixed frame 4 and the movable frame 5 rotate, they drive the fabric to rotate, thereby adjusting the processing surface of the fabric.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
