[0020] The utility model is described in detail below in conjunction with the accompanying drawings.

[0021] Reference Figure 1-Figure 3 A warp knitting machine for producing decorative fabrics, comprising a yarn guide frame 1, a plurality of material guide rollers 2 are rotatably connected to the yarn guide frame 1, a material winding assembly is arranged on one side of the yarn guide frame 1, and the material winding assembly comprises a U-shaped frame 3, a first mounting frame 4 and a driving assembly for driving two first mounting frames 4 to move closer to or away from each other are symmetrically arranged on the inner side of the U-shaped frame 3;

[0022] The driving assembly includes a telescopic part 8 symmetrically arranged on the U-shaped frame 3, and the telescopic ends of the two telescopic parts 8 are respectively fixedly connected to the two first mounting frames 4. The U-shaped frame 3 is also fixedly provided with a first cylinder 9 for driving the first mounting frame 4 to move. The telescopic part 8 can adapt to the movement of the first mounting frame 4 and maintain the support for the first mounting frame 4, thereby reducing the load of the first cylinder 9, improving the stability of the first mounting frame 4, and further improving the stability of the reel driven by the air shaft 6 during the winding process;

[0023] The telescopic portion 8 includes a fixing rod 81 fixedly arranged on the inner wall of the U-shaped frame 3 , a sliding sleeve 82 is provided on the fixing rod 81 , and an end of the sliding sleeve 82 is fixedly connected to the first mounting frame 4 .

[0024] A limiting column 83 is fixed on the inner wall of the sliding sleeve 82, and a limiting groove 84 is opened on the fixed rod 81 for the limiting column 83 to slide. When the first cylinder 9 pushes the first mounting frame 4 to move, the sliding sleeve 82 slides along the fixed rod 81. At the same time, the limiting column 83 slides in the limiting groove 84. The limiting groove 84 contacts the limiting column 83, thereby limiting the moving distance of the first mounting frame 4 to prevent the sliding sleeve 82 from separating from the fixed rod 81.

[0025] A first motor 5 is fixedly provided on the first mounting frame 4, and an inflatable shaft 6 is transmission-connected to the output shaft of the first motor 5. A support frame 7 for placing a reel is provided on the side of the U-shaped frame 3 away from the yarn guide frame 1. The support frame 7 has at least two positions for placing the reel, and also includes a moving component. The moving component is used to drive the U-shaped frame 3 to move so that the inflatable shaft 6 loads the reel on the support frame 7 and moves to the yarn guide frame 1 to reel up the fabric.

[0026] The moving assembly includes mounting seats 10 symmetrically arranged on both sides of the support frame 7, and the two mounting seats 10 are rotatably connected with a screw rod 11, and the screw rod 11 is connected to a second motor 12 that drives it to rotate, and a screw nut 13 is threadedly sleeved on the screw rod 11, and a second mounting frame 14 is fixedly connected to the screw nut 13, and a second cylinder 15 is fixedly provided on the second mounting frame 14, and the output ends of the two second cylinders 15 are respectively fixedly connected to the bottom of the two U-shaped frames 3.

[0027] A bearing seat 16 is fixedly mounted on the first mounting frame 4, and the inflatable shaft 6 is fixedly mounted on the inner ring of the bearing seat 16. The bearing seat 16 improves the stability of the installation of the inflatable shaft 6 and improves the operating stability of the inflatable shaft 6 when rotating and winding.

[0028] Working principle: When the warp knitting machine is in use, the first motor 5 is first used to rotate to drive the air shaft 6 to rotate, thereby driving the reel fixed by the air shaft 6 to rotate to reel the warp-knitted fabric. After the reeling is completed, the second motor 12 is used to drive the screw 11 to rotate, so that the screw nut 13 moves toward the direction close to the support frame 7 under the action of the thread, thereby driving the U-shaped frame 3 to move as a whole. When the reel moves to the top of the support frame 7, the second cylinder 15 retracts to drive the U-shaped frame 3 to descend, thereby placing the reel on the support frame 7, and the air shaft 6 releases the fixation of the reel, and the first cylinder 9 retracts to drive the air shaft 6 to withdraw from the inside of the reel;

[0029] Then, under the control of the screw rod 11, the two inflatable shafts 6 move horizontally to the two sides of the empty reel, the first cylinder 9 extends to drive the inflatable shaft 6 to extend into the interior of the reel and press against its inner wall, then the second cylinder 15 extends to drive the U-shaped frame 3 to rise, the screw rod 11 continues to control the U-shaped frame 3 to move horizontally to the winding position to continue to wind the fabric, thereby quickly completing the automatic replacement of the reel.

[0030] The first cylinder 9, the second cylinder 15, the first motor 5 and the second motor 12 of the utility model are all controlled and coordinated by being electrically connected to the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0031] The utility model drives the two air shafts 6 to press against and detach from the reels through the driving assembly, and drives the reels to move to the support frame 7 through the moving assembly for quick replacement of the reels, so that no manual intervention is required after the reels are wound up, thereby improving the overall work efficiency of warp knitting.

[0032] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
