[0031] In this embodiment, the third fabric cover body forming device 4 includes a third fabric feeding mechanism 41, a buffer material mechanism 42, a first pulling mechanism 43, a front pressing mechanism 44, a third fabric cover body thermoforming mechanism 45, a rear pressing mechanism 46, a second pulling mechanism 49, a slitting mechanism 47 and a discharge station 48 which are arranged in sequence. The flip loading device 16 is used to flip the third fabric cover body at the discharge station 48 to the overlapping station 12; the first pulling mechanism 43 and the second pulling mechanism 49 synchronously pull the third fabric; specifically, the third fabric feeding mechanism 41, the buffer material mechanism 42, the first pulling mechanism 43, the front pressing mechanism 44, the rear pressing mechanism 46, the second pulling mechanism 49 and the slitting mechanism 47 can all adopt existing mechanisms, which will not be repeated here.

[0032] In actual application, the third fabric supplied by the third fabric feeding mechanism 41 passes through the buffer mechanism 42, the first pulling mechanism 43, the front pressing mechanism 44, the third fabric cover body thermoforming mechanism 45, the rear pressing mechanism 46, the second pulling mechanism 49, and the slitting mechanism 47 in sequence. The third fabric feeding mechanism 41 supplies the third fabric to the buffer mechanism 42, and the buffer mechanism 42 buffers the third fabric for a certain length. When the third fabric cover body thermoforming mechanism 45 thermo-presses the third fabric to form a third fabric cover body, the front pressing mechanism 44 and the rear pressing mechanism 46 are in a state of pressing the third fabric to ensure the quality of the thermo-pressed third fabric cover body. After the third fabric cover body is formed on the third fabric, the front pressing mechanism 44 and the rear pressing mechanism 46 release the third fabric, and the first pulling mechanism 43 and the second pulling mechanism 49 pull the third fabric synchronously to realize the transportation of the third fabric, and the third fabric with the third fabric cover body formed will move to the discharge station 48, and the slitting mechanism 47 cuts the third fabric to form a single third fabric cover body on the discharge station 48, and the flipping feeding device 16 flips the third fabric cover body on the discharge station 48 to the processing and forming carrier 3 at the stacking station 12, and the third fabric cover body flips from the opening facing downward to the opening facing upward, so that the third fabric cover body is overlapped on the second fabric cover body.

[0033] In this embodiment, the third fabric cover body thermoforming mechanism 45 includes a thermoforming frame 451 installed on the machine 1, an upper thermoforming driver 452 installed on the thermoforming frame 451, a thermoforming die 453 installed at the output end of the upper thermoforming driver 452, a thermoforming convex die 454 which is lifted and lowered on the machine 1 and located below the thermoforming die 453, and a lower thermoforming driver 455 which is installed on the machine 1 and used to drive the thermoforming convex die 454 to lift and lower. The thermoforming die 453 is matched with the thermoforming convex die 454 in a concave and convex manner; specifically, the upper thermoforming driver 452 and the lower thermoforming driver 455 can both use cylinders.

[0034] In actual application, the third fabric is located between the thermoforming die 453 and the thermoforming punch 454, the upper thermoforming driver 452 drives the thermoforming die 453 to move downward, and the lower thermoforming driver 455 drives the thermoforming punch 454 to move upward, until the thermoforming die 453 and the thermoforming punch 454 cooperate to perform hot press molding on the third fabric to form a third fabric cover.

[0035] In this embodiment, the third fabric cover body thermoforming mechanism 45 also includes a pressure plate 456 arranged below the thermoforming die 453 and corresponding to the side portion of the thermoforming die 453, a guide rod 457 connected to the bottom surface of the pressure plate 456, and a spring 458 sleeved on the outside of the guide rod 457. The guide rod 457 is slidably connected to the side portion of the thermoforming punch 454, and the two ends of the spring 458 are elastically in contact with the pressure plate 456 and the side portion of the thermoforming punch 454 respectively.

[0036] In actual application, the edge plate 456 supports the edge of the third fabric, and the thermoforming die 453 moves down until the thermoforming die 453 presses the edge of the third fabric on the edge plate 456 to ensure the stability of the third fabric, and the thermoforming convex mold 454 moves up and cooperates with the thermoforming die 453 to perform thermoforming with the third fabric to form a third fabric cover on the third fabric. When the thermoforming die 453 presses the edge of the third fabric on the edge plate 456, the spring 458 will be compressed, and the rebound force of the spring 458 will cause the edge plate 456 to press the third fabric tightly against the edge of the thermoforming die 453, and the spring 458 plays a buffering role on the thermoforming die 453 to prevent the thermoforming die 453 and the thermoforming convex mold 454 from having a hard impact collision.

[0037] In this embodiment, the circulating conveying mechanism 2 includes a circulating conveying sprocket set 21 disposed on the machine 1, an annular guide rail 22 disposed outside the circulating conveying sprocket set 21, a guide wheel 23 disposed on the circulating conveying seat 24, and a plurality of circulating conveying seats 24 respectively connected to a plurality of chain links of the circulating conveying sprocket set 21, the processing and forming carrier 3 is disposed on the circulating conveying seat 24, and the processing and forming carrier 3 is elastically connected to the circulating conveying seat 24 via an elastic buffer component 25; the guide wheel 23 rolls against the annular guide rail 22. Specifically, the elastic buffer component 25 can be a compression spring component, which will not be described in detail here.

[0038] In actual application, the chain on the circulating conveying sprocket set 21 rotates intermittently and drives the multiple processing and forming carriers 3 to rotate intermittently and cyclically, so that the processing and forming carriers 3 pass through each processing mechanism in sequence; during the cyclic movement of the processing and forming carrier 3, the guide wheel 23 rolls along the annular guide rail 22, thereby improving the movement stability of the processing and forming carrier 3. When each processing mechanism processes the fabric on the processing and forming carrier 3, the elastic buffer component 25 plays a buffering role to prevent the processing mechanism from having a hard impact collision with the processing and forming carrier 3.

[0039] In this embodiment, the sponge strip attaching device 7 includes a bracket 71 mounted on the machine 1, a sponge strip peeling mechanism 72 arranged on the bracket 71, a sponge strip receiving and transferring mechanism 73 movably arranged at the peeling end of the sponge strip peeling mechanism 72, a sponge strip attaching mechanism 74 movably arranged at one side of the sponge strip receiving and transferring mechanism 73 and located above the processing and forming carrier 3, and a supporting mechanism 75 movably arranged below the processing and forming carrier 3. The sponge strip receiving and transferring mechanism 73 is used to transfer the sponge strip peeled by the sponge strip peeling mechanism 72 to the sponge strip attaching mechanism 74. Specifically, the sponge strip peeling mechanism 72 can adopt an existing peeling mechanism, which will not be described in detail here.

[0040] In actual application, the sponge strip peeling mechanism 72 peels off the sponge strip on the material strip, and the sponge strip transferring mechanism 73 picks up the peeled sponge strip and transfers it to the sponge strip sticking mechanism 74. The sponge strip sticking mechanism 74 sticks the sponge strip on the inner wall of the overlapping cover body after ultrasonic welding. In the process of sticking the sponge strip, the supporting mechanism 75 supports the outer wall of the overlapping cover body. With the cooperation of the supporting mechanism 75 and the sponge strip sticking mechanism 74, the sponge strip can be stably and firmly stuck.
