[0021] Through the buffer mechanism 5 arranged between the fixed end of the cloth cylinder 4 and the rack body 1, the elastic support bottom plate 51, the elastic top plate 52 and the buffer pad 53, and the air bag 54 embedded in the buffer pad 53, the impact force intensity on the upper swing arm 2 caused by inertia during cloth feeding is reduced, and the frequency of deformation or fatigue fracture of the upper swing arm 2 caused by impact is reduced.

[0022] Moreover, in the embodiment, the elastic top plate 52 is provided with a first magnet 521 at the middle position of the side surface close to the elastic support bottom plate 51, the first magnet 521 is fixedly connected with the elastic top plate 52, the elastic support bottom plate 51 is provided with a second magnet 511 corresponding to the first magnet 521 at the middle position of the side surface close to the elastic top plate 52, and the first magnet 521 and the second magnet 511 repel each other, the second magnet 511 is fixedly connected with the elastic support bottom plate 51, and the first magnet 521 and the second magnet 511 are both neodymium iron boron magnets.

[0023] The first magnet 521 and the second magnet 511 are both neodymium iron boron magnets, the magnetic poles of the opposite faces of the first magnet 521 and the second magnet 511 are the same, and the same poles repel each other, so the first magnet 521 and the second magnet 511 repel each other, thereby consuming part of the kinetic energy transmitted by the elastic supporting bottom plate 51 and the elastic top plate 52, and making the buffering effect of the buffering mechanism 5 better.

[0024] Meanwhile, in the embodiment, the buffering pad 53 is a rubber pad, and a limiting spring 531 is embedded in the buffering pad 53 and at one side of the air bag 54.

[0025] The limiting spring 531 not only bears the external force and buffers the external force to a certain extent when the air bag 54 is deformed, but also supports the elastic top plate 52 when the air bag 54 is damaged, thereby preventing the elastic top plate 52 from tilting due to the damage of the air bag 54.

[0026] In addition, in the embodiment, a first hinge shaft 522 is arranged in the middle of the side of the elastic top plate 52 away from the elastic supporting bottom plate 51, the fixed end of the cloth oil cylinder 4 is provided with a first lug 41, the first lug 41 is sleeved on the first hinge shaft 522, the top of the frame body 1 is fixed with two bearing seat bodies 71, the swing arm rotating shaft 7 is arranged on the two bearing seat bodies 71, the second hinge shaft 21 is arranged on the side of the upper swing arm 2 close to the cloth oil cylinder 4, the free end of the cylinder rod of the cloth oil cylinder 4 is provided with a second lug, the second lug is sleeved on the second hinge shaft 21, a third hinge shaft 61 is arranged on the side of the cloth car 6, and the third lug 31 is fixed at the bottom end of the lower swing arm 3 and sleeved on the third hinge shaft 61.

When the cloth car 6 moves to the target position, the cylinder rod of the cloth oil cylinder 4 stops moving, so that the cloth car 6 stops moving. During the process from high-speed operation to sudden stop of the cylinder rod of the cloth oil cylinder 4, the upper swing arm 2 generates impact due to inertia, the impact is transmitted to the buffering mechanism 5 through the cloth oil cylinder 4, and the impact strength generated by the inertia of the upper swing arm 2 during the cloth distribution is reduced through the buffering effect of the buffering mechanism 5, and the frequency of deformation or fatigue fracture of the upper swing arm 2 due to the impact is reduced.

[0028] In addition, in the embodiment, the upper swing arm 2 is an arc-shaped rotating arm, the second hinge shaft 21 divides the upper swing arm 2 into a rotating arm upper end 22 and a rotating arm lower end 23, and the length of the rotating arm upper end is less than the length of the upper swing arm 2.

[0029] Through the arrangement, the arc-shaped rotating arm is more in line with the mechanical principle in structure design, has a good stress point and better structural strength, and can improve the appearance of the mechanical structure.

[0030] In use, the cylinder rod of the distributing oil cylinder 4 is extended to drive the upper swing arm 2 to rotate clockwise, the lower swing arm 3 is driven to rotate by the upper swing arm 2, and the distributing vehicle 6 is driven to move forward along the guide rail 8 by the lower swing arm 3. When the distributing vehicle 6 moves to the target position, the cylinder rod of the distributing oil cylinder 4 stops moving, so that the distributing vehicle 6 stops moving. In the process from high-speed operation to sudden stop of the cylinder rod of the distributing oil cylinder 4, the upper swing arm 2 generates an impact due to inertia, and the impact is transmitted to the buffer mechanism 5 through the distributing oil cylinder 4.
