The cuff panel 10 consists of an integral sword-shaped upper panel 11 and lower panel 12. The dotted line represents the inner folded edge. The cuff folding device's platform 100 is fixedly mounted with a lower panel folding mechanism 200, a second lifting plate 500 located on the same side of the lower panel folding mechanism 200, and an upper panel folding mechanism 300.

[0063] Sheet folding mechanism 200

[0064] like Figure 4 As shown, the lower sheet folding mechanism 200 is provided with a first table 201, and the upper surface of the first table 201 is provided with a lower sheet discharge area 202 (as shown in FIG. Figure 4 The lower sheet discharging area 202 is provided with a plurality of suction holes 203, and a movable lower sheet folding plate 210 is provided on one side of the suction hole 203 for folding the inner fold of the lower sheet.

[0065] The first table 201 is provided with a sheet folding plate mounting groove 204, and the sheet folding plate 210 is embedded in the sheet folding plate mounting groove 204. The sheet folding plate 210 is equipped with a second two-axis driving mechanism 211. The second two-axis driving mechanism 211 includes a second lifting mechanism 212 and a Y-axis sliding mechanism 213. The second lifting mechanism 212 is used to drive the sheet folding plate 210 flush with the first table 201 in the sheet folding plate mounting groove 204 to extend upward, and the Y-axis sliding mechanism 213 is used to drive the extended sheet folding plate 210 to slide towards the sheet discharge area 202 (i.e. Figure 3 The lower sheet 12 is folded in the Y direction) to form an inner fold of the lower sheet.

[0066] Feed sheet folding mechanism 300

[0067] The frame 306 of the upper sheet folding mechanism 300 is provided with a second table 301, and the second table 301 is provided with an upper sheet discharge trough 302. Three movable upper sheet folding plates 310 are installed on the second table 301 and are located around the upper sheet discharge trough 302. Figure 5 As shown, each upper sheet folding plate 310 is connected to the cylinder 311 through a mounting block 312, and the cylinder 311 drives each upper sheet folding plate 310 to perform telescopic movement to fold the sword-shaped upper sheet 11 to form an inner folding edge.

[0068] The second table 301 is provided with a third two-axis driving mechanism 303, such as Figure 7 As shown, the second table 301 is connected to the third two-axis drive mechanism 303 through the mounting plate 307, and the third two-axis drive mechanism 303 is mounted on the frame 306. The third two-axis drive mechanism 303 includes a third lifting mechanism 304 and a third X-axis sliding mechanism 305. The third lifting mechanism 304 is used to drive the second table 301 to move vertically, and the third X-axis sliding mechanism 305 is used to drive the second table 301 to move along the length direction of the upper sheet discharging trough 302 (i.e. Figure 3 The upper sheet folding plates 310 slide in the X direction, and the drag chain 308 provides traction and protection. It should be noted that each upper sheet folding plate 310 is mounted on the second table 301. Therefore, when the third two-axis drive mechanism 303 drives the second table 301 to move, each upper sheet folding plate 310 will also move synchronously.

[0069] like Figure 8As shown, the upper sheet folding mechanism 300 is also provided with a multi-axis movable upper sheet shaping plate 320 that can be embedded in the upper sheet discharge trough 302. The upper sheet shaping plate 320 is installed on the first two-axis driving mechanism 322 through the upper sheet shaping fixing plate 321. The first two-axis driving mechanism 322 is installed on the frame 306 of the upper sheet folding mechanism 300. The first two-axis driving mechanism 322 includes a first lifting mechanism 323 and a first X-axis sliding mechanism 324. The first lifting mechanism 323 is used to drive the upper sheet shaping plate 320 to lift and lower in the height direction of the upper sheet discharge trough 302. The first X-axis sliding mechanism 324 is used to drive the upper sheet shaping plate 320 to slide along the length direction of the upper sheet discharge trough 302.

[0070] The upper sheet discharge trough 302 and the upper sheet shaping plate 320 are both sword-shaped. The thickness of the upper sheet shaping plate 320 is less than the depth of the upper sheet discharge trough 302. The upper sheet discharge trough 302 has an opening at one end in the longitudinal direction for the upper sheet shaping plate 320 to be removed. After the upper sheet shaping plate 320 presses the sword-shaped upper sheet 11 into the upper sheet discharge trough 302, it plays a role in shaping the contour, facilitating the upper sheet folding plate 310 to better fold and form the inner folding edge of the sword-shaped upper sheet 11.

[0071] The upper sheet folding mechanism 300 is equipped with a turning mechanism 330 for driving the upper sheet folding mechanism 300 to turn over as a whole.

The flipping motor 331 is connected to the pulley 333 fixed on the upper sheet folding mechanism 300 through the belt 332. The flipping motor 331 drives the upper sheet folding mechanism 300 to flip as a whole.

[0072] A fan-shaped brake rod block 334 is fixed at the rotating shaft of the pulley 333, and a limit block 335 is provided on the frame 306 of the upper sheet folding mechanism 300. The fan-shaped brake rod block 334 and the limit block 335 cooperate to provide a limit for the flipping of the upper sheet folding mechanism 300, thereby preventing the upper sheet folding mechanism 300 from flipping over.

The large lifting cylinder 501 is connected with a small lifting cylinder 503 through a lifting plate cylinder connecting block 504, and the small lifting cylinder 503 is connected with the second lifting plate 500. Through the large lifting cylinder 501 and the small lifting cylinder 503, multi-stage lifting of the second lifting plate 500 can be realized. In the initial state, the second lifting plate 500 is significantly lower than the table top height, the first stage is lifted to a height slightly lower than the first table top 201 through the large lifting cylinder 501, and then is lifted to be flush with the first table top 201 through the small lifting cylinder 503.
