DETAILED DESCRIPTION

[0033] The present invention is further described in detail below in conjunction with specific embodiments:

[0034] like Figure 1 - Figure 5As shown, a bath towel hemming device is used to fold the edge of a bath towel twice and sew it into a hemming. It includes a base 1, the front end of the base 1 is connected to a bath towel cutting device, and the cut bath towel is transported to the working surface 11 of the base 1 through a transfer device.

[0035] The working surface 11 supports the middle of the bath towel. The first folding part 21 and the second folding part 22 on both sides of the bath towel that need to be hemmed are symmetrically arranged along the center line of the bath towel. The first folding part 21 is far away from the center line of the bath towel, and the second folding part 22 is close to the center line of the bath towel. In order to cover the edge of the bath towel after sewing ( Figure 4 The projection of the second folded portion 22 on the horizontal plane is not less than half of the projection of the first folded portion 21 on the same plane.

[0036] A folding assembly is provided on one side of the base 1 corresponding to the edge of the bath towel, and the folding assembly includes a first folding mechanism and a second folding mechanism. The first folding mechanism includes a first folding plate 3 provided corresponding to the first folding portion 21 of the bath towel, and the second folding mechanism includes a second folding plate 4 provided corresponding to the second folding portion 22 of the bath towel. The first folding plate 3 and the second folding plate 4 are both connected to a folding drive device 5, and can be lifted and lowered and moved in the horizontal direction under the drive of the folding drive device 5. In this embodiment, the folding drive device 5 is independently provided as two sets corresponding to the first folding plate 3 and the second folding plate 4, and the two sets of folding drive devices 5 are formed by a combination of multiple cylinders provided in the horizontal and vertical directions.

[0037] A positioning mechanism 6 is also provided above the base 1, and the positioning mechanism 6 includes a positioning pressure plate 61, which is lifted and lowered and moves along a horizontal plane under the drive of a positioning drive device 62, and the positioning drive device 62 is slidably provided on a positioning base 63, and the positioning base 63 is provided as a gantry structure, the bottom of which is connected to the base 1, and the top crossbeam is provided with the positioning drive device 62. In this embodiment, the positioning drive device 62 is composed of a servo motor 621, a screw mechanism 622 and a slide rail 623.

[0038] The end surface of the positioning plate 61 close to the edge of the bath towel is straight. When the positioning plate 61 abuts against the bath towel driven by the positioning drive device 62, the straight end surface abuts against the inner sides of the first folding portion 21 and the second folding portion 22 of the bath towel in turn, and is correspondingly located at the first folding station and the second folding station, thereby providing positioning for the folding of the first folding portion 21 and the second folding portion 22.

[0039] Driven by the folding driving device 5 , the first folding plate 3 and the second folding plate 4 have a first action station, a second action station and a third action station.

[0040] When the first folding plate 3 is in the first action position, that is, the folding driving device 5 is not working, the upper surface of the first folding plate 3 is flush with the working surface 11 of the base 1, and is used to carry the first folded portion 21 of the bath towel. At this time, the positioning plate 61 is in the first folding position, and the spacing between the positioning plate 61 and the adjacent end surface of the first folding plate 3 is not less than the thickness of the bath towel.

[0041] Combination Figure 4 and Figure 5 As shown, when the folding driving device 5 drives the first folding plate 3 to lift upward and enter the second action station, the lower surface of the first folding plate 3 is higher than the upper surface of the positioning plate 61 by a height of the thickness of the bath towel, and the first folding portion 21 of the bath towel is folded along the end surface of the positioning plate 61 close to the first folding plate 3.

[0042] When the folding drive device 5 drives the first folding plate 3 to move horizontally toward the center line of the bath towel and enters the third action station, the lower surface of the first folding plate 3 slides against the bath towel to the top of the positioning plate 61, so that a chamber for shaping the first folding part 21 is formed between the base 1, the positioning plate 61, and the first folding plate 3.

[0043] After the first folding portion 21 is folded and formed, the positioning plate 61 moves toward the inner side of the second folding portion 22 in contact with the surface of the bath towel until the distance between the positioning plate 61 and the adjacent ends of the second folding plate 4 is not less than two layers of bath towels. The positioning plate 61 has a bend, so that the part of the positioning plate 61 away from the positioning drive device 62 is horizontal, and the part close to the positioning drive device 62 is tilted upward with a certain slope, which prevents the positioning plate 61 from wrinkling the bath towel when it moves in contact with the surface of the bath towel.

[0044] When the positioning platen 61 moves to the inner side of the second folding portion 22 and is in the second folding position, the second folding plate 4, driven by the folding drive device 5, lifts the second folding portion 22 of the bath towel together with the folded portion of the first folding portion 21 until the vertical distance between the lower surface of the second folding plate 4 and the upper surface of the positioning platen 61 is not less than the thickness of two layers of bath towels.

[0045] When the folding drive device 5 drives the second folding plate 4 to move horizontally toward the center line of the bath towel and enters the third action station, the lower surface of the second folding plate 4 slides against the bath towel to the top of the positioning plate 61, so that a chamber for the second folding part 22 to be formed is formed between the base 1, the positioning plate 61, and the second folding plate 4.

[0046] When working:

[0047] Step 1: The positioning plate 61 moves to the inner side of the first folding portion 21 of the bath towel driven by the positioning drive device 62, and the first folding plate 3 moves upward under the drive of the folding drive device 5, and enters the second action station from the first action station to lift the first folding portion 21 of the bath towel upward.

[0048] Step 2: The first folding plate 3 moves horizontally toward the middle of the bath towel, and the lower surface slides against the bath towel, so that the first folding portion 21 of the bath towel is folded and placed on the upper surface of the positioning plate 61. The bath towel is in a C-shaped space formed by the working surface 11, the positioning plate 61 and the first folding plate 3.

[0049] Step 3: The positioning plate 61 moves horizontally toward the middle of the bath towel to the inner side of the second folding portion 22 of the bath towel. The second folding plate 4 and the first folding plate 3 move upward under the drive of the folding drive device 5, and enter the second action station from the first action station to lift the second folding portion 22 of the bath towel upward.

[0050] Step 4: The second folding plate 4 moves horizontally toward the middle of the bath towel, and the lower surface slides against the bath towel, so that the second folded portion 22 of the bath towel is folded and placed on the upper surface of the positioning plate 61. The bath towel is in the C-shaped space formed by the working surface 11, the positioning plate 61 and the second folding plate 4. Then, the bath towel as a whole is driven by the transfer device into the sewing machine, and the folded edge is sewn.
