When the first motor 3 is started, the screw 4 begins to rotate according to the principle of threaded transmission. The slider 5, threadedly connected to the screw 4, then moves linearly along the chute, driving the inverted T-shaped feed seat 6 on the slider 5 to move synchronously. A first inclined surface 7 at one end of the feed seat 6 facilitates the placement and initial transfer of the unwinding assembly. When placing the unwinding assembly, the operator can easily push it along the inclined surface to a higher position, initiating the automatic feeding process. The carrying assembly includes a slide 8, a first elastic member 9, a second elastic member 10, a lifting plate 11 and a carrying frame 12. The first elastic member 9 is symmetrically provided on the left and right sides of the upper part of the feed seat 6, and the slide 8 is slidably provided on the top wall of the lower part of the left and right sides of the feed seat 6. The two ends of the first elastic member 9 are respectively connected to the side wall of the upper part of the feed seat 6 and the slide 8. Two groups of second elastic members 10 symmetrically arranged front and back are also provided on the slide 8. The lifting plate 11 is provided above the second elastic member 10. The lifting plate 11 is provided with the carrying frame 12 at one end close to the center of the feed seat 6. The lifting plate 11 is provided with a second inclined surface 13 at one end away from the carrying frame 12. A groove for carrying the docking roller 15 is provided above the carrying frame 12. The upper part of the carrying frame 12 away from the transmission assembly is also provided with a third inclined surface 17 that penetrates the groove; The unwinding assembly slides down the first inclined surface 7 onto the carrier 12, then engages the third inclined surface 17 of the carrier 12. The carrier 12 is positioned on the lifting plate 11 near the center of the feed seat 6. The lifting plate 11 is supported by the second elastic member 10 below and the slides 8 on both sides. The slides 8 are connected to the feed seat 6 via the first elastic member 9. When the unwinding assembly is placed into the groove, the slides 8 can be displaced appropriately. During the subsequent feeding process of the feed seat 6, the carrier 12 remains stable. The first elastic member 9 and the second elastic member 10 are both composed of a spring-mounted damping rod. The unwinding assembly consists of a center roller 14, a docking roller 15, and a protective plate 16. The center roller 14 is used to wind the linen and cotton fabric, and the protective plates 16 on both sides provide protection and auxiliary support. The docking roller 15 is the key part for subsequent connection with the transmission assembly. It extends through the protective plate 16 to facilitate precise docking with the transmission assembly.

A second motor 23 is further provided on one group of the mounting seats 20, and the output end of the second motor 23 passes through the corresponding mounting seat 20 and is connected to the corresponding turntable 21; As the feed seat 6 is fed, when the second inclined surface 13 of the slide plate 8 contacts the guide plate 22, the first elastic member 9 contracts. At this time, the slide plate 8 drives the lifting plate 11 to move toward the unwinding assembly through the second elastic member 10. The load plate completes the center positioning of the unwinding assembly until the slider 5 contacts the chute, completing the feeding of the feed seat 6 and the unwinding assembly is in the specified position. At this time, the pusher 19 feeds under the support of the side plate 18. The mounting seat 20 is in an inverted T shape and has a guide rod 25. The guide rod 25 passes through the side plate 18 to ensure that the mounting seat 20 is stable and does not shake when moving. A plug-in is provided on the turntable 21 at one end of the mounting seat 20. The plug-in includes an insert block 26 and a spline 27. A slot is provided at the corresponding position of the docking roller 15. The slot opening has a first chamfer and the plug-in end has a second chamfer. The pusher 19 works and the mounting seat 20 approaches the unwinding assembly. With the help of the chamfer, the plug-in smoothly inserts into the slot to achieve a stable connection. A second motor 23 on a set of mounting seats 20 is used to drive the turntable 21 to rotate, driving the unwinding assembly to unwind and transport materials for subsequent weaving processes; In the above process, the plug-in first contacts the slot, and the lifting plate 11 is also provided with a fourth inclined surface 28 on the side close to the mounting seat 20. Then the mounting seat 20 cooperates with the fourth inclined surface 28, and the lifting plate 11 drives the supporting frame 12 to move downward until the plug-in is fully plugged into the slot. At this time, the highest end of the supporting frame 12 is lower than the lowest end of the docking roller 15.

[0017] During actual use, a plurality of groups of evenly spaced semi-cylinders 24 are provided in the groove to reduce the contact area between the groove and the docking roller 15 and facilitate the centering displacement of the unwinding assembly.

[0018] In this embodiment, the plug-in includes an insert block 26 and a spline 27. Several groups of splines 27 are provided on the outside of the insert block 26. A first chamfer is provided at the open end of the slot, and a second chamfer is provided at one end of the plug-in close to the slot.
