The output end of the third electric push rod 51 is fixedly connected to the bottom end of the limit plate 5.

[0028] In the prior art, although the towel can be hemmed, it is not convenient to adjust the width of the hem. Since towels have different thicknesses, for thick towels, the width of the hem may be too small, resulting in the hem coming apart. For thin towels, the width of the hem may be too large, resulting in an unbeautiful hem. During work, different hemming widths are set according to different towel thicknesses, and the parameters are uploaded to the computer program. The computer program controls the third electric push rod 51. The output end of the third electric push rod 51 drives the limit plate 5 to move to a suitable position. Then, one end of the towel is aligned with the limit plate 5, and the first electric push rod 23 can be started. The first electric push rod 23 drives the rack 22 to move. The rack 22 drives the gear 21 to rotate. The gear 21 drives the rotating shaft and the flipping plate 2 to rotate. The flipping plate 2 flips the towel, realizing the function of pressing the edges of towels with different thicknesses with different widths.

[0029] Further, as Figure 1 and Figure 3 shown, a first slide rail 3 is fixedly connected to the top of the workbench 1. A moving frame 31 is slidably connected to the first slide rail 3. A second electric push rod 32 is fixedly connected to the top of the moving frame 31. The output end of the second electric push rod 32 extends to the bottom of the moving frame 31 and is fixedly connected to a lifting plate 33. A plurality of connecting rods 34 are uniformly fixedly connected to the bottom of the lifting plate 33. The connecting rods 34 are respectively matched with the rectangular openings. The bottoms of the connecting rods 34 are all rotatably connected with rollers 35 through mounting seats.

[0030] During operation, during the hemming process, the moving frame 31 is at one end of the first slide rail 3 close to the sewing equipment main body 43. For the towel after flipping and hemming, by driving the first slide rail 3 to drive the moving frame 31 to move, the moving frame 31 drives the second electric push rod 32, the lifting plate 33, the connecting rods 34 and the rollers 35 to move. Move to one end of the towel hemming. Turn on the second electric push rod 32. Drive the lifting plate 33 to move through the second electric push rod 32. Drive the connecting rods 34 and the rollers 35 to move through the lifting plate 33 until the rollers 35 compact the towel hemming. Turn on the first electric push rod 23. Through the cooperation of the rack 22 and the gear 21, flip the flip plate 2 onto the workbench 1 to realize the function of compacting the hemmed towel.

[0031] Further, as Figure 1 and Figure 2 shown, a second slide rail 4 is fixedly connected to one end of the workbench 1 close to the flip plate 2. A slider 41 is slidably connected to the top of the second slide rail 4. The top of the slider 41 is rotatably connected with a rotating seat 42 through a bearing. A driving mechanism is arranged in the slider 41. The output end of the driving mechanism is fixedly connected to the bottom of the rotating seat 42. The top of the rotating seat 42 is fixedly connected with a sewing equipment main body 43.

[0032] During operation, the sewing equipment main body 43 is initially located on the second slide rail 4. After hemming and compacting are completed, the rotating seat 42 and the sewing equipment main body 43 are rotated to a position perpendicular to the second slide rail 4 through the driving mechanism. By adjusting the sewing equipment main body 43, determine the position of the sewing needle on the sewing equipment main body 43. Then drive the sewing equipment main body 43 to perform sewing. During the sewing process, the slider 41 drives the rotating seat 42 and the sewing equipment main body 43 to slide on the second slide rail 4. After sewing is completed, rotate the sewing equipment main body 43 parallel to the second slide rail 4 again.

[0033] Further, as Figure 1 , Figure 2 and Figure 6As shown in the figure, two fixed plates 61 are fixedly connected to the bottom of one end of the workbench 1 away from the flipping plate 2. A bidirectional ball screw 63 is rotatably connected to the fixed plates 61 through bearings. Two positioning plates 6 are symmetrically and threadedly connected to the bidirectional ball screw 63. One of the fixed plates 61 is fixedly connected with a motor 64, and the output shaft of the motor 64 is fixedly connected to one end of the bidirectional ball screw 63.

[0034] During operation, when the towel is placed on the workbench 1, in order to prevent the towel from tilting and affecting the quality of hemming and sewing, it is necessary to turn on the motor 64. The motor 64 drives the bidirectional ball screw 63 to rotate. A ball nut seat is provided at the connection between the bidirectional ball screw 63 and the positioning plate 6. Through the ball nut seat, the radial movement of the positioning plate 6 is ensured, and the towel is limited to a flat state by the positioning plate 6.

[0035] Furthermore, as Figure 6 shown, two guide rods 62 are fixedly connected between the two fixed plates 61, and the positioning plates 6 are all slidably connected to the guide rods 62.

[0036] During operation, when the positioning plate 6 is moving, the positioning plate 6 slides on the guide rod 62, and the guide rod 62 limits the positioning plate 6 in the horizontal direction.

[0037] Furthermore, as Figure 4 shown, a limit block 24 is fixedly connected to the side wall of the rack 22 close to the workbench 1, and the limit block 24 slides on the workbench 1.

[0038] During operation, when the rack 22 is moving, the rack 22 drives the limit block 24 to slide on the workbench 1, and the limit block 24 limits the rack 22 in the horizontal direction.

[0039] Working principle: During operation, different hemming widths are set according to the thickness of different towels, and the parameters are uploaded to the computer program. The computer program controls the third electric push rod 51. The output end of the third electric push rod 51 drives the limiting plate 5 to move to a suitable position. Then, one end of the towel is aligned with the limiting plate 5, and the first electric push rod 23 can be started. The first electric push rod 23 drives the rack 22 to move. The rack 22 drives the gear 21 to rotate. The gear 21 drives the rotating shaft and the turning plate 2 to rotate. The turning plate 2 turns the towel, realizing the function of hemming towels with different thicknesses with different widths; during the hemming process, the moving frame 31 is at one end of the first slide rail 3 close to the sewing equipment main body 43. For the towel after turning and hemming, the first slide rail 3 is driven to drive the moving frame 31 to move. The moving frame 31 drives the second electric push rod 32, the lifting plate 33, the connecting rod 34 and the roller 35 to move to one end of the towel hemming. The second electric push rod 32 is started. The second electric push rod 32 drives the lifting plate 33 to move. The lifting plate 33 drives the connecting rod 34 and the roller 35 to move until the roller 35 compacts the towel hemming. The first electric push rod 23 is started. Through the cooperation of the rack 22 and the gear 21, the turning plate 2 is turned to the workbench 1, realizing the function of compacting the hemmed towel; the sewing equipment main body 43 is initially located on the second slide rail 4. After the hemming and compacting are completed, the rotating seat 42 and the sewing equipment main body 43 are turned to a position perpendicular to the second slide rail 4 through the driving mechanism. By adjusting the sewing equipment main body 43, the position of the sewing needle on the sewing equipment main body 43 is determined, and then the sewing equipment main body 43 is driven to sew. During the sewing process, the slider 41 drives the rotating seat 42 and the sewing equipment main body 43 to slide on the second slide rail 4. After the sewing is completed, the sewing equipment main body 43 is rotated parallel to the second slide rail 4 again; when the towel is placed on the workbench 1, in order to prevent the towel from tilting and affecting the quality of hemming and sewing, the motor 64 needs to be started. The motor 64 drives the bidirectional ball screw 63 to rotate. A ball nut seat is provided at the connection between the bidirectional ball screw 63 and the positioning plate 6. The positioning plate 6 is ensured to move radially through the ball nut seat. The towel is limited to a straight state through the positioning plate 6.
