Figure 1、 2 The blocking material mechanism 3 (see FIGS. 1, 2, 3, and 4) is composed of a blocking material mechanism front plate and a blocking material mechanism back plate (both not marked), which are in the shape of a "V", with their upper and lower portions clamping a lining tube (not marked, forming a double-layer structure) and being fixed by screws (both not marked) at the back of the rack plate 1 on the right side of the material trough 2.

[0028] The sliding material mechanism 4 (see FIGS. 1, 2, 3, and 4) is composed of a sliding material mechanism front plate and a sliding material mechanism back plate (both not marked), which are in the shape of a "(", with their upper and lower portions clamping a lining tube (not marked, forming a double-layer structure) and being fixed by a sliding material mechanism upper fixing screw and a sliding material mechanism lower fixing screw (both not marked) at the back of the rack plate 1 on the right side of the material trough 2. Figure 1 2

[0029] The blocking material mechanism 3 and the sliding material mechanism 4 enclose the material trough 2 of the rack plate 1 into a long and narrow cavity that is large at the top and small at the bottom.

[0030] The matched pushing material correction device (not shown in the figure) is arranged at the lower portion of the pushing material emptying plate 5.

[0031] The pushing material emptying plate 5 is a rectangular plate with variations: the left side is a straight line, the left end of the lower side to the middle right portion is a straight line, the upper side is an upper curve 20 from the left end to the middle upper portion of the right side, the right side is a middle curve 21 from the middle upper portion to the middle portion of the right side, and the right portion of the lower side is a lower curve 22 from the middle portion of the right side to the middle right portion of the lower side. The intersections of the upper curve 20, the middle curve 21, and the lower curve 22 (the line type can be a circular arc curve, a hyperbolic curve, or other types of curves, and in this example, a circular arc curve is adopted) are smoothly transitioned.

[0032] The pushing material emptying shaft mechanism is composed of a pushing material emptying shaft tube 12, a pushing material emptying shaft 6, a pushing material emptying shaft front bearing 16, a pushing material emptying shaft rear bearing 14, a pushing material emptying shaft hole lining tube 19, a pushing material emptying shaft axis lining tube 17, an axis end cover 11, and an axis tube stop screw 18.

[0033] ​​​The push material emptying rotating shaft 6 is a stepped shaft, the large end of which is fixed to the front of the machine frame plate 1 at the middle left side of the lower material groove 2. A through hole is formed in the middle of the push material emptying rotating shaft cylinder 12. The push material emptying rotating shaft rear bearing 14, the push material emptying rotating shaft hole lining cylinder 19, the push material emptying rotating shaft shaft lining cylinder 17 and the push material emptying rotating shaft front bearing 16 are sequentially arranged in the through hole of the push material emptying rotating shaft cylinder 12 and are sleeved into the middle front part of the push material emptying rotating shaft 6 from back to front. The step of the push material emptying rotating shaft 6 abuts against the inner ring of the push material emptying rotating shaft rear bearing 14. The push material emptying rotating shaft hole lining cylinder 19 and the push material emptying rotating shaft shaft lining cylinder 17 abut against the outer ring and the inner ring of the push material emptying rotating shaft rear bearing 14 and the push material emptying rotating shaft front bearing 16 respectively. The shaft end cover 11 with a fixing screw is additionally arranged at the front end face of the push material emptying rotating shaft cylinder 12 and is used for blocking the inner ring of the front end face of the push material emptying rotating shaft front bearing 16. The shaft cylinder stop screw 18 radially penetrates the cylinder wall of the push material emptying rotating shaft cylinder 12, abuts against the outer wall of the push material emptying rotating shaft hole lining cylinder 19 and prevents the axial movement of the push material emptying rotating shaft cylinder 12. The power input arm 10 and the push material emptying plate connecting arm 13 are respectively arranged at the left and right sides of the cylinder wall of the push material emptying rotating shaft cylinder 12 and are respectively used for connecting the push material emptying power mechanism and the left side of the push material emptying plate 5.

[0034] The push material emptying power mechanism is composed of the power connection pin shaft 15, the power connection head 9 and the push material emptying power cam connecting rod 8. The power connection pin shaft 15 penetrates the left end of the power input arm 10 at the left side of the push material emptying rotating shaft cylinder 12. The front end of the power connection pin shaft 15 penetrates the power connection head 9 (a fish eye joint, i.e. a self-lubricating rod end joint bearing). The upper end of the push material emptying power cam connecting rod 8 is connected to the lower end of the power connection head 9. The lower end of the push material emptying power cam connecting rod 8 is connected to the cam mechanism (not shown in the figure) on the main shaft of the full-automatic braiding machine.

[0035] The push material emptying device of the full-automatic braiding machine is used in cooperation with the full-automatic braiding machine.

[0036] Before use, the push material emptying plate 5 is in the inclined state of left up and right down under the drive of the cam mechanism on the main shaft of the full-automatic braiding machine. At this time, the lower material groove 2 of the machine frame plate 1 is surrounded by the material blocking mechanism 3 and the material sliding mechanism 4 to form a long and narrow cavity with large upper part and small lower part in the unobstructed state (see the attached drawing 2). Figure 4The weaving material silk falls into the long and narrow cavity from the upper end of the discharging groove 2 in a disordered and irregular arrangement. Then, the cam mechanism on the main shaft of the automatic weaving machine drives the pushing emptying plate 5 to swing counterclockwise around the pushing emptying rotating shaft 6 into a horizontal state through the pushing emptying power cam connecting rod 8, the power connecting head 9, the power input arm 10, the pushing emptying rotating shaft cylinder 12 and the pushing emptying plate connecting arm 13. During the swinging process, the upper curve 20 of the pushing emptying plate 5 pushes the weaving material silk on the right upper part upward and scatters, only leaving a small amount of weaving material silk at the lower part of the upper curve 20 (i.e. the lower part of the long and narrow cavity), and at the same time, the lower part of the long and narrow cavity is closed to form a closed cavity with only a small amount of weaving material silk, and the closed state is maintained for a proper time to allow the pushing and correcting device sufficient time to push and correct the small amount of weaving material silk in the long and narrow cavity. After the pushing and correcting is completed, the pushing emptying plate 5 is driven by the cam mechanism on the main shaft of the automatic weaving machine to swing clockwise around the pushing emptying rotating shaft 6 into an inclined state of left upper right lower, so that the weaving material silk in the upper part of the discharging groove 2 falls into the long and narrow cavity again to repeat the previous action.

[0037] The pushing emptying device for the automatic weaving machine is matched with the automatic weaving machine, and can weave various mats, curtains and decorative fabrics.
