[0017] Attached Figure 3 It is a front view of the warp yarn being led from the warp creel to the yarn collecting mechanism;

[0019] The utility model is further described below in conjunction with the accompanying drawings.
[0020] As attached Figures 1 to 4The staggered distributed warp unwinding mechanism comprises a warp frame 1, on which there are a plurality of yarn reels 2, and yarn drums wound with warp rolls are correspondingly mounted on the yarn reels 2. The warp frame 1 is provided with a plurality of axial base surfaces 3 distributed in a stepped manner, and one end of the yarn reel 2 is mounted on the axial base surface 3. The shapes and lengths of the yarn reels 2 on the warp frame 1 are consistent. When the yarn reels are mounted on the yarn reels 2, the position where the warp yarn is led out on the yarn reel is associated with the yarn reel 2 where it is located, and the position of one end of the yarn reel 2 away from the warp frame 1 will be different due to the different axial base surfaces 3 where it is located. Therefore, the position where the warp yarn is led out on the yarn reel will be associated with the corresponding axial base surface 3, so that the warp yarns led out by the yarn reels on each axial base surface 3 are staggered along the stepped distribution of the axial base surface 3, so that the led-out warp yarns are not easily interfered with each other. The warp frame 1 of the utility model can be used for a prepreg machine, a loom, and a weaving machine for weaving various hollow, multi-layer, 3D and other woven fabrics.
[0021] As attached Figure 1 As shown in FIG. 1 , the multiple axial base surfaces 3 on the warp yarn frame 1 are distributed in a stepped manner along the horizontal direction, so that the warp yarns drawn out from the yarn reels on each axial base surface 3 are staggered in the horizontal direction.
[0022] The installation heights of the yarn reels 2 on the various axial base surfaces 3 are different from each other, so that the warp yarns drawn out from the yarn reels on different axial base surfaces 3 are staggered in the vertical direction.
[0023] A plurality of yarn reels 2 are vertically distributed on the same axial base surface 3, and the warp yarns drawn out from the yarn reels on the same axial base surface 3 are staggered in the vertical direction.
[0024] As attached Figure 1 As shown in the figure, the yarn reels 2 on the warp frame 1 are arranged in rows and columns, with multiple yarn reels 2 on the same axis base 3 arranged in columns, and yarn reels 2 on different axis bases 3 arranged in rows. There is a certain inclination angle between the arrangement direction of the yarn reels 2 arranged in rows and the horizontal direction, so that the warp yarns drawn out from each yarn reel on the yarn reel 2 in the row are staggered in the vertical direction.
[0025] The inclination angles of any two rows of yarn reels 2 are different, so that the warp yarns drawn from the yarn reels 2 in different rows are not likely to interfere with each other.
[0026] One end of the warp frame 1 is a lead-out end 4, and the lead-out end 4 of the warp frame 1 is opposite to the yarn collecting mechanism 6, and the warp yarn of the yarn reel is led out in the direction of the lead-out end 4. Figure 3 and 4In one embodiment shown in , the wire collecting mechanism 6 is a wire collecting plate, and a plurality of wire collecting holes are opened on the wire collecting plate, and the warp yarns drawn out from the warp frame 1 are correspondingly inserted into the wire collecting holes. Along the direction away from the lead-out end 4, the spacing between the yarn reels 2 in the same row on each axial base surface 3 gradually increases. Since the warp yarns need to be gradually gathered in the direction of the lead-out end 4, the yarn reels 2 in the same row close to the lead-out end 4 of the warp frame 1 are more dense, and the yarn reels 2 in the same row away from the lead-out end 4 of the warp frame 1 are more sparse, so that the warp yarns are not easy to interfere with each other in the process of gradual gathering.
[0027] Details are as attached Figure 2 As shown in FIG, in the warp frame 1, the arrangement direction of the yarn reels 2 in the top row is tilted upwards away from the lead-out end 4, and the arrangement direction of the yarn reels 2 in the bottom row is tilted downwards away from the lead-out end 4. That is, from top to bottom, in the direction away from the lead-out end 4, the inclination angles of the yarn reels 2 in each row gradually change, and gradually change from tilting upwards to tilting downwards.
[0028] The axial base surfaces 3 are parallel to each other, and the yarn reel 2 is vertically mounted on the axial base surfaces 3 .
[0029] In practical applications, the warp frame 1 of the utility model is a warp frame 1 that can adapt to the constant tension requirements of warp unwinding and has adjustable tension. Most traditional warp frames 1 control tension through friction, and the tension is imprecise and varies greatly. In the utility model, a transmission hole is provided on the shaft base surface 3, and a motor 5 is installed on the back of the warp frame 1. The motor 5 can be a servo motor or a torque motor. The output shaft of the motor 5 extends out of the transmission hole, and one end of the yarn reel 2 close to the shaft base surface 3 is connected to the output shaft of the motor 5. The rotation of the motor 5 is controlled by a controller such as a PLC or a computer, and the motor 5 drives the yarn reel to rotate. The output torque of the yarn reel 2 is accurately controlled by the cooperation of the controller and the motor 5 to achieve constant tension unwinding of the warp.
[0030] In the utility model, through the stepped distribution of the shaft base surface 3 and the inclined arrangement of the row of yarn reels 2, the warp yarns drawn from the warp rack 1 can be staggered with each other, the warp yarns are not easy to interfere with each other, and the operation of the warp unwinding mechanism is more stable.
[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
