[0030] The spreading mechanism 1 further includes a buffer 13 , which is mounted on the frame via a fixing seat 25 .

[0031] like Figure 1 As shown, the strut assembly 4 includes a strut 1 41, a strut 2 42 and a strut 3 43. The strut 1 41 and the strut 2 42 are respectively fixed on the L-shaped mounting plate 5 and connected to the large-diameter open clamp cylinder 3. The strut 2 42 is provided with a strip guide block 421. The guide block 421 has a guiding function and is used for guiding the cloth cover. The strut 3 43 is connected to the large-diameter open clamp cylinder 3 through a connecting plate 431. The strut 1 41, the strut 2 42 and the strut 3 43 are all cylindrical structures, and the center lines of the strut 1 41, the strut 2 42 and the strut 3 43 are in the same plane. The diameter of the strut 3 43 is larger than that of the other struts and is mainly used to support the entire cloth cover.

[0032] like Figure 1 、 Figure 2 and Figure 3 As shown, in this embodiment, the large-diameter open clamp cylinder 3 adopts the HFT large-diameter open clamp cylinder, the rotary cylinder 2 adopts the HRQ rotary cylinder, and the ultra-thin cylinder 8 adopts the SDA ultra-thin cylinder. The HRQ rotary cylinder is installed vertically and is perpendicular to the HFT large-diameter open clamp cylinder. The HRQ rotary cylinder is fixed to the fixed seat assembly 7 through the cylinder mounting plate 16 and is connected to the reinforcing ribs 71 on both sides of the fixed seat assembly 7. A fixed plate 72 is provided at the bottom of the fixed seat assembly 7, and the fixed plate 72 is connected to the top of the arch support plate 17.

[0033] In the specific production process, the suction cup mechanism transports the opened cloth cover to the opening mechanism 1, and the cloth cover is supported by the support rod assembly 4 on the opening mechanism 1. Specifically, the support rod 3 43 supports the middle part of the cloth cover, and the two sides of the cloth cover are supported by the support rod 1 41 and the support rod 2 42 respectively. The support rod 2 42 is provided with a strip guide block 421, and the guide block 421 has a guiding function; the piston rod of the HRQ rotary cylinder rotates 90°, and the HFT large-diameter opening clamp cylinder is driven to rotate 90° through the rotating device 6, and the support rod assembly 4 also rotates 90 °, causing the cloth cover on the support rod to rotate 90°; the first cylinder 19 is opened, and the piston rod of the first cylinder 19 pushes the mounting plate 12 to move linearly. Slide 14 and guide rail 15 are provided below the mounting plate 12. The rack 10 moves linearly with the mounting plate 12, causing the rack 10 to rotate the gear 9 below the fixed seat assembly 7. The gear 9 is mounted in the middle of the door arch support plate 17 via the rotating shaft 18. During the rotation of the gear 9, the entire opening mechanism 1 is rotated 90°, causing the cloth cover to change from horizontal to vertical. The limit screw 11 on the mounting plate 12 has a limiting function when the first cylinder 19 is in operation, ensuring that the mounting plate 12 does not contact the first cylinder 19. At the same time, the SDA ultra-thin cylinder opens and is connected to the base plate 26 through a piston rod, and a slider three 22 and a guide rail three 23 are provided on the side of the base plate 26 close to the SDA ultra-thin cylinder, and a slider two 20 and a guide rail two 21 are provided on the side of the base plate 26 close to the first cylinder 19. The SDA ultra-thin cylinder opens and pushes the base plate 26 to move. The base plate 26 moves on the corresponding guide rails through the slider two 20 and the slider three 22, thereby driving the expansion mechanism 1 to move in a straight line and transporting the cloth cover to the cloth cover device. Buffers 13 are provided on both sides of the base plate 26. The buffers 13 play a buffering role on the movement of the base plate 26 during the opening and closing process of the SDA ultra-thin cylinder. The slider two 20 and the guide rail two 21 and the slider three 22 and the guide rail three 23 ensure the smooth operation of the expansion mechanism 1 when the cylinder is in action. After the clamping claws of the cloth covering device clamp the cloth cover and take it out from the support rod, the HRQ rotary cylinder rotates 90 degrees, closes the first cylinder 19 and drives the rack 10, so that the gear 9 rotates the spreading mechanism 1 and rotates 90 degrees. The SDA ultra-thin cylinder is closed to make the spreading mechanism 1 retract, and the spreading mechanism 1 returns to its initial state. By following this action cycle, automatic cloth covering and automatic cloth covering delivery can be completed.
