[0029] Towel 3. DETAILED DESCRIPTION

[0030] The present invention is further described in detail below in conjunction with specific embodiments:

[0031] like Figure 1 As shown, the present invention is applied to the folding of towel products, and folding is performed twice. During the first folding, the first limiting plate is used to limit the position, and the first flap drives the towel to fold the two sides of the towel along the first crease end, so that the two sides of the towel are folded inward; during the second folding, it is performed on the basis of the first folding, and the second limiting plate is used to limit the position, and the second flap drives the towel to fold along the second crease end. And through the matching setting of the second flap and the notch on the second limiting plate, after folding, the second flap further presses the towel, making the folded towel more compact and avoiding its deformation in subsequent transportation.

[0032] Specifically, a towel folding mechanism includes a first folding component 1 and a second folding component 2 connected to the first folding component 1, the first folding component 1 includes a first conveying device 11, a first folding device 12 arranged on both sides of the conveying direction of the first conveying device 11 and a first limiting device 13 arranged above the first conveying device 11; the first folding device 12 includes a first flap 121, the first limiting device 13 includes a first limiting plate 131, the first limiting plate 131 limits the towel, and the first flap 121 completes the first folding of the towel.

[0033] like Figure 2 As shown, the first folding device 12 includes a first cylinder 122 connected to the first flap 121 and having a vertical driving direction, and a second cylinder 123 connected to the first cylinder 122 and having a horizontal driving direction; the first cylinder 122 can drive the first flap 121 to move downward and press the towel on the first conveying device 11; the second cylinder 123 can drive the first flap 121 to move toward or away from the first conveying device 11 through the first cylinder 122.

[0034] Two first limiting plates 131 are provided and are symmetrically arranged in the conveying direction of the first conveying device 13 ; the side where the two first limiting plates 131 are close to each other is the first crease end 1311 , and the first flap 121 drives the towel to fold along the first crease end 1311 .

[0035] The two first limit plates 131 are respectively connected to the third cylinder 132 at the upward end close to the conveying direction of the first conveying device 13, and the third cylinder 132 can drive the first limit plates 131 to move in the vertical direction; the third cylinder 132 is connected to the first driving device 133, and the first driving device 133 is connected to the two third cylinders 132 at the same time, and can drive the two first limit plates 131 to move in opposite directions at the same time by driving the two third cylinders 132.

[0036] In this embodiment, the two first limit plates 131 are located between the two first flaps 121 when pressing the towel, and the distance between the side of the first flap 121 close to the first limit plate 131 and the first fold end 1311 should be greater than the thickness of a towel, so as to avoid the first flap 121 from interfering with the first limit plate 131 when performing the folding action. After folding, the towel is actually wrapped around the first limit plate 131, and the third cylinder 132 drives the first limit plate 131 to move slightly upward. At the same time, the first drive device 133 drives the two first limit plates 131 to move slightly closer to each other, so that the towel and the first limit plate 131 are more relaxed, so that the first conveying device 11 can convey the towel and detach from the first limit plate 131. In addition, in order to further improve the conveying capacity of the first conveying device 11 for the towel, the first conveying device 11 can be set as a plurality of parallel and synchronous first conveyor belts 111, and the interval arrangement of the first conveyor belts 111 further increases the friction force on the towel, so that the towel is easier to detach from the first limit plate 131.

[0037] like Figure 3-Figure 5 As shown, the second folding assembly 2 includes a second conveying device 21 , a second folding device 22 arranged below the second conveying device 21 , and second limiting devices 23 symmetrically arranged on both sides of the conveying direction of the second conveying device 21 .

[0038] The second conveying device 21 includes a plurality of second conveyor belts 211 arranged in parallel, with a gap 212 between two adjacent second conveyor belts 211; the second folding device 22 includes a plurality of second flaps 222 connected by a rotating shaft 221 and a flip driving device 223 connected to the rotating shaft 221 and capable of driving the second flaps 222 to rotate by the rotating shaft 221. The second flaps 222 are arranged directly below the gaps 212 and have a width smaller than that of the gaps 212. The plurality of second flaps 222 correspond to the plurality of gaps 212 one by one, and when folded, the second flaps 222 can pass through the gaps 212.

[0039] The second flip plate 222 includes a connecting block 2221 fixedly connected to the rotating shaft 221 and a connecting plate 2222 connected to the connecting block 2221, wherein the connecting block 2221 is arranged below the second conveying device 21; the connecting plate 2222 is arranged horizontally, and is connected to the lower end of the connecting plate 2222 at the downward end in the conveying direction of the second conveying device 21; when flipping, the connecting plate 2222 flips 180° along the rotating shaft 221 and moves to the top of the second conveying device 21.

[0040] The second limiting device 23 includes a fourth cylinder 232 connected to the second limiting plate 231 and capable of driving the second limiting plate 231 to move in the vertical direction, and a fifth cylinder 233 connected to the fourth cylinder 232 and capable of driving the fourth cylinder 232 to move in the horizontal direction; driven by the fifth cylinder 233, the second limiting plates 231 on both sides of the second conveying device 21 can move toward each other at the same time; driven by the fourth cylinder 232, the second limiting plate 231 can move downward and press the towel on the second conveying device 21.

[0041] The second limiting device 23 includes a second limiting plate 231, and a notch 2311 is arranged on the second limiting plate 231; in the conveying direction of the second conveying device 21, the second limiting plate 231 is arranged at the downstream end of the second flap 222, and the second flap 222 can be inserted into the notch 2311 or directly above the notch 2311 after flipping. The second limiting plate 231 is arranged at the second folding end 2312 at the upstream end close to the conveying direction of the second conveying device 21, and the opening of the notch 2311 is arranged at the second folding end 2312; when folding, the second flap 222 drives the towel to fold along the second folding end 2312.

[0042] In this embodiment, the process of folding the towel is as follows: Figure 6 As shown, during the first folding, the towel product is transported to the first conveyor 11 by a robot arm or other means, and the towel is overlapped on the first flaps 121 on both sides of the transmission direction of the first conveyor 11; the first limit plate 131, driven by the first driving device 133 and the third cylinder 132, first moves toward each other and then moves downward, so that the first limit plate 131 presses the towel, and the two first limit plates 131 are between the two first flaps 121; the first cylinder 122 lifts the first flap 121 upward, The two sides of the towel are folded upward along the first crease end 1311; then the second cylinder 123 drives the two first flaps 121 to move toward each other, so that the two sides of the towel are folded inward; after folding, the first flap 121 is reset under the drive of the first cylinder 122 and the second cylinder 123, and the two first limit plates 131 move slightly toward each other and slightly upward at the same time under the drive of the first driving device 133 and the third cylinder 132; then the first conveying device 11 is started to transfer the folded towel to the second conveying device 21.

[0043] like Figure 7 As shown, when the towel is transferred to the second conveying device 21, the second folding starts. When the towel is transported to the bottom of the second limit plate 231 by the second conveying device 21, the second limit plates 231 on both sides, driven by the fourth cylinder 232 and the fifth cylinder 233, first move toward each other, then move downward and press the towel. At this time, the notch 2311 on the second limit plate 231 coincides with the interval 212; the flip driving device 223 drives the second flap 222 to rotate through the rotating shaft 221. During the rotation of the second flap 222, the connecting plate 2222 supports the towel, and the towel is folded along the second fold end 2312 until the second flap 222 is folded. 222 flips 180°, and the towel is folded. At this time, the connecting plate 2222 is above the towel and presses the towel downward, and the connecting plate 2222 is directly above the notch 2311; then the second flap 222 is reset under the drive of the flip driving device 223; the two second limit plates 231 are driven by the fourth cylinder 232 to first move slightly upward to reduce the pressure on the towel, and then move in the opposite direction under the drive of the fifth cylinder 233 and detach from the towel; the towel is transmitted to the next process under the drive of the second conveying device 21.
