[0041] It should be noted that both the first driving member and the second driving member adopt existing stepping motors.

[0042] In this embodiment, by cooperating with the provided moving assembly 22 and the flipping assembly 23, on the one hand, the outer cover cloth and the inner cover cloth can be automatically and synchronously folded and covered on the sponge pad, which is convenient for the stapling and forming of the outer cover cloth and the inner cover cloth, and the folding accuracy is high to avoid the sponge pad from being compressed and deformed. The gap between the inner cover cloth and the sponge pad is small, and the sponge pad is more filled in the inner cover cloth; on the other hand, the inner cover cloth can be pressed and limited at the bending part of the outer cover cloth and the inner cover cloth, which is convenient for the outer cover cloth and the inner cover cloth to be folded to the specified position, and at the same time, the inner cover cloth is prevented from separating from the outer cover cloth during the folding process, thereby ensuring the neatness of the stacking of the outer cover cloth and the inner cover cloth.

[0043] In detail, the first driving member drives the first threaded block 222 to move the outer edge frame 223 toward the static support plate 211 through the first bidirectional threaded rod 221, so that the insertion rod 2313 is inserted into the insertion hole 2314 on the side of the dynamic support plate 213, and the third pressure rod 2325 is pressed on the inner cover cloth. The first pressure rod 2321 moves to the hinge of the static support plate 211 and the short-connection plate 212 and presses the inner cover cloth. At the same time, the second pressure rod 2323 moves to the hinge of the dynamic support plate 213 and the short-connection plate 212 and presses the inner cover cloth.

The dynamic support plate 213 folds upward with the short-connection plate 212. When the short-connection plate 212 folds to the side of the sponge pad, the blocking bar 2324 blocks the second pressure rod 2 The second driving member drives the disc 2311 to continue to rotate, so that the second pressure rod 2323 can prevent the short-circuit plate 212 from continuing to fold, thereby ensuring that the short-circuit plate 212 is in a vertical state and close to the side of the sponge pad. Then, the second driving member drives the disc 2311 to continue to rotate, and the second sliding block at the end of the second pressure rod 2323 slides relatively along the arc extension plate 2322, and the turning rod 2312 continues to fold the movable support plate 213 through the insertion rod 2313, and the first sliding block at the end of the turning rod 2312 moves relatively along the turning rod 2312 until the movable support plate 213 is folded to the upper surface of the sponge pad, and the first driving member drives the first threaded block 222 to move back and reset with the outer edge frame 223 through the first bidirectional threaded rod 221, so that the first pressure rod 2321, the second pressure rod 2323 and the insertion rod 2313 move back and reset for the next use.

[0044] Further, if Figure 1 and Figure 6-Figure 8 As shown, the first power assembly 31 includes a first screw rod 311 rotatably arranged on the frame 1, a first mounting frame 312 threadedly arranged on the first screw rod 311, two groups of mounting blocks 313 symmetrically arranged on the first mounting frame 312 and slidingly matched with the frame 1, and a third driving member arranged on the frame 1 and used to drive the first screw rod 311; The smoothing assembly 32 includes two groups of lifting holes 321 symmetrically opened on the mounting block 313, a second bidirectional threaded rod rotatably arranged between the lifting holes 321, two groups of second threaded blocks 322 threadedly arranged on the second bidirectional threaded rod, a smoothing roller 323 rotatably arranged on the second threaded block 322, a fourth driving member embedded in the second threaded block 322 and used to drive the smoothing roller 323, and a fifth driving member arranged on the mounting block 313 and used to drive the second bidirectional threaded rod.

[0045] It should be noted that the third driving element, the fourth driving element and the fifth driving element all adopt existing stepping motors.

[0046] It is worth mentioning that the two smoothing rollers 323 of the same lifting hole 321 smooth the upper and lower sides of the folded inner cloth outwards; the two smoothing rollers 323 of the other lifting hole 321 smooth the upper and lower sides of the folded outer cloth inwards, and the two smoothing rollers 323 are provided with a plurality of groups of suction holes along the axial direction, which are connected to the existing negative pressure machine through a hose.

Then, the fourth driving member drives the smoothing roller 323 to rotate, so that the upper and lower sides of the inner cover cloth are rolled inward, and the smoothing roller 323 continues to advance, thereby smoothing the upper and lower sides of the inner cover cloth inward in turn, until the winding roller 333 at the end of the center rod 331 abuts against the short-circuit plate 212, and the winding roller 333 rolls the short-circuit plate 212 at The inner cloth is rolled up inward, and then, the fifth driving member drives the two smoothing rollers 323 to approach each other through the second bidirectional threaded rod, so that the two smoothing rollers 323 smooth the upper and lower sides of the inner cloth together along the side of the sponge pad until the upper and lower sides of the inner cloth are clamped and connected, and then, the vacuum suction cups 214 on the static support plate 211 and the dynamic support plate 213 stop working, and the winding roller 333 rolls up the outer cloth at the short-circuit plate 212 inward, and the other two smoothing rollers 323 with suction holes suck the upper and lower sides of the outer cloth.

[0052] In this embodiment, the stapling assembly 33 is provided to synchronously stapling the side edges of the outer cover cloth and the side edges of the inner cover cloth.

[0053] In detail, when the two smoothing rollers 323 clamp the upper and lower sides of the inner cover cloth for docking, and the other two smoothing rollers 323 clamp the upper and lower sides of the outer cover cloth for docking, the docking sides of the inner cover cloth and the docking sides of the outer cover cloth are respectively located below the pressing wheel 334, and then, the third driving member drives the first mounting frame 312 through the first screw rod 311 to move the smoothing rollers 323 horizontally away from the short-circuit plate 212. At the same time, the first hydraulic member 335 drives the first stapler 336 to reciprocate and rise and fall, and the first stapler 336 synchronously sews the side edges of the outer cover cloth and the side edges of the inner cover cloth.
