[0029] Material blocking mechanism 10 (see appendix) Figure 1 The material blocking mechanism (as shown) consists of a front plate (not marked) and a rear plate (not drawn) of the material blocking mechanism. The front plate and the rear plate of the material blocking mechanism are arranged in a... The upper and lower parts are respectively fitted with liner cylinders (not shown, forming a double-layer structure) and are respectively fixed to the left side of the feed chute 3 in front of the frame plate 15 by screws.

[0030] Material sliding mechanism 1 (see attachment) Figure 1 The slide mechanism consists of a front plate and a rear plate (both unmarked). The front and rear plates are shaped like "(". The upper and lower parts are respectively fitted with bushings (not shown, forming a double-layer structure) and are fixed to the right side of the feed chute 3 in front of the frame plate 1 by upper fixing screw 2 and lower fixing screw 12 of the slide mechanism.

[0031] Material pushing and dispersing mechanism (see attachment) Figure 1 The material (shown) is composed of a front plate 13 of the material pushing mechanism, a rear plate 7 of the material pushing mechanism, and a material pushing power mechanism (none of which are marked).

[0032] The front plate 13 and the rear plate 7 of the material pushing mechanism are in the same position. The upper part is respectively set in front of the front plate of the sliding mechanism and behind the rear plate of the sliding mechanism in the lower part of the sliding mechanism 1, forming a clamping shape; the material pushing and dispersing power mechanism is set in the lower right part behind the frame plate 15, and it passes through the mounting groove 14 to connect the lower ends of the front plate 13 and the rear plate 7 of the material pushing and dispersing mechanism.

[0033] The matching material rolling device and material clamping device (not shown in the figure) are respectively set in the cavity of the double-layer structure at the bottom of the material blocking mechanism 10 and the material sliding mechanism 1.

[0034] The matching receiving device and feeding device (not shown in the figure) are respectively installed in the feeding trough 11.

[0035] The material feeding limiting plate 6 is shaped like a "(". A support with a hole protrudes to the right at the lower part for connecting the rear end of the material feeding limiting rotating shaft mechanism. At the lower part, there is also a material feeding limiting crank 21 that protrudes to the left and is recessed to the back, and the lower end also turns to the right (to limit the falling of the braided material yarn). At the same time, the upper end is also tilted forward and has a spring hook hole 16 for easy hooking of the spring.

[0036] The left side of the material limiting crank 21 abuts against the lower right side of the material blocking mechanism 10 (the front plate of the material blocking mechanism) (located at the lower port of the material feeding trough 3 and the upper end of the feeding trough 11), and its rear side is placed in front of the lower part of the front plate of the material sliding mechanism 1.

[0037] The material feeding limiting shaft mechanism consists of a material feeding limiting shaft 22, a material feeding limiting shaft cylinder 8, a material feeding limiting rear bearing 23, a material feeding limiting front bearing 17, a material feeding limiting bearing hole liner 24, a material feeding limiting shaft liner 25, a material feeding limiting bearing cover 19, a material feeding limiting bearing cover screw 18, and a material feeding limiting bearing hole liner stop screw 20.

[0038] The material feeding limiting shaft cylinder 8 is a cylinder with a through hole in the middle. Its rear end is inserted into the support hole protruding to the right in the lower part of the material feeding limiting plate 6. The rear part of the material feeding limiting shaft 22 has a step. The rear bearing 23 and the front bearing 17 of the material feeding limiting shaft are installed in sequence from back to front. Between the rear bearing 23 and the front bearing 17, there is also a material feeding limiting bearing hole liner 24 and a material feeding limiting shaft liner 25. Then, it is inserted into the inner hole of the material feeding limiting shaft cylinder 8. A material feeding limiting bearing cover 19 (blocking the inner ring of the front bearing 17) is installed at its end and fixed with a material feeding limiting bearing cover screw 18. At the same time, the material feeding limiting bearing hole liner fixing screw 20 is radially passed through the cylinder wall of the material feeding limiting shaft cylinder 8 and abuts against the outer wall of the material feeding limiting bearing hole liner 24 to prevent the material feeding limiting shaft cylinder 8 from moving axially.

[0039] The material feeding limiting bridge mechanism consists of a material feeding limiting bridge plate 9, a material feeding limiting rotating shaft 22, and a lower fixing screw 12 for the sliding mechanism. The material feeding limiting bridge plate 9 is shaped like a "<", with pin holes at both its upper and lower ends. The rear end of the material feeding limiting rotating shaft 22 (which is integrated into one piece) passes through the pin hole at its upper end, and the pin hole at its lower end is fixed to the lower right front end of the sliding mechanism front plate of the sliding mechanism 1 by the lower fixing screw 12.

[0040] The blanking limiting and retaining mechanism is composed of a blanking limiting and retaining spring 4 and a blanking limiting and retaining spring hooking column 5, and the blanking limiting and retaining spring hooking column 5 is arranged at the upper right part of the rack plate 15; the left end of the blanking limiting and retaining spring 4 is hooked in the spring hooking hole 16 at the upper end of the blanking limiting and retaining plate 6, and the right end is hooked at the front end of the blanking limiting and retaining spring hooking column 5.

[0041] The blanking limiting and retaining device for the full-automatic braiding machine is used in cooperation with the full-automatic braiding machine.

[0042] Before use, the blanking limiting and retaining plate 6 swings clockwise around the blanking limiting and retaining pivot 22 under the pulling force of the blanking limiting and retaining spring 4 at the upper end, so that the left side of the blanking limiting and retaining crank 21 at the lower end always abuts against the right side of the lower end of the blocking mechanism front plate of the blocking mechanism 10 (at the lower end of the blanking groove 3 and the upper end of the feeding groove 11).

[0043] In use, the end of the braiding material falls from the blanking groove 3 of the rack plate 15 downward and accumulates in the long and narrow cavity with the upper part being large and the lower part being small, which is formed by the right side of the blocking mechanism and the left side of the sliding material mechanism, at this time, the gap at the lower part of the long and narrow cavity is basically slightly larger than the thickness of a braiding material, but since the thickness of the braiding material itself is not large, generally, the accumulation is formed, that is, in most cases, 2-3 or even more than 3 braiding materials are stacked, which causes mutual crowding, and further causes the braiding material to be unable to naturally pass through the long and narrow cavity and enter the feeding groove 11 at the lower end of the blanking groove 3.

[0044] At this time, the matched rubbing device rubs the accumulated braiding material at the lower part and forms a one-by-one arrangement, then the clamping device clamps and moves downward the arranged braiding material, when the lowermost end of the clamped braiding material breaks through the limitation of the blanking limiting and retaining crank 21 and reaches the preset position at the lower part, then the clamping device is released, the lowermost end of the braiding material immediately falls to the receiving device at the lower part and is received by the receiving device, then the clamping device swings to the left and downward direction and is clamped by the pushing device, and then the pushing device pushes the braiding material to the left middle part of the feeding groove 11, and then the feeding device of the full-automatic braiding machine feeds the braiding material into the braiding.

[0045] At the same time, when the clamping device is released, the second braiding material arranged at the lowermost end is immediately limited by the blanking limiting and retaining crank 21 at the lowermost end of the long and narrow cavity and waits for the next clamping period.

[0046] The blanking limiting and retaining device for the full-automatic braiding machine is used in cooperation with the full-automatic braiding machine, and can be used for braiding various mats, various curtains and various decorative fabrics.
