[0048] The present application will be further described in detail below in combination with specific embodiments:

[0049] As shown in FIGS. 1-13, the present application is applied to the manufacturing of towels or towel-like articles. First, the fabric raw material for manufacturing the towel is transmitted to the distribution mechanism through the feeding frame; then the fabric is dragged for a certain length and cut through the first dragging assembly and the cutting assembly of the distribution mechanism to form the towel blank; the towel blank is transmitted to the hemming mechanism through the second dragging assembly; in the hemming mechanism, the towel blank is transmitted through the second transmission assembly on both sides, and at the same time, the hemming device completes the overlock, and the thread on the towel product is cut off and pressure- maintained through the cutting assembly to form the finished product of the towel product. The hemming mechanism is provided at two places and is respectively arranged on both sides of the distribution mechanism; the distribution mechanism can transmit the cut-off towel blank to the hemming mechanism on both sides.

[0050] Specifically, a superfine warp and weft towel machine comprises a feeding frame 1, as shown in FIG. 1, the feeding frame 1 is provided with a first transmission assembly 11, and the first transmission assembly 11 transmits the fabric to the distribution mechanism 2. The first transmission assembly 11 can be provided with multiple, and multiple fabrics can be transmitted at the same time.

[0051] As shown in FIGS. 1-5, the distribution mechanism 2 comprises a cutting assembly 21 and a distribution assembly 22. The cutting assembly 21 cuts the fabric transmitted by the first transmission assembly 11, and the cut-off fabric forms the towel blank and is transmitted to the hemming mechanism 3 by the distribution assembly 22.

[0052] As shown in FIGS. 4-5, the cutting assembly 21 is provided with a pressing device 23 close to one side of the feeding frame 1. The pressing device 23 comprises an upper pressing rod 231, a lower pressing rod 232 and a sixth driving device 233 for driving the upper pressing rod 231 to move downward. Before cutting, the sixth driving device 233 drives the upper pressing rod 231 to move downward to press the fabric against the lower pressing rod 232 to limit the fabric. It should be noted that the pressing device 23 is further away from the cutting assembly 21 to ensure that the fabric at the cutting assembly 21 remains flat when the pressing device 23 limits the fabric, which facilitates neat cutting.

[0053] The cutting assembly 21 comprises an upper cutter 211, a lower cutter 212 and a third driving device 213 for driving the upper cutter 211 to move downward. When the fabric is cut, the pressing assembly presses the fabric, and the third driving device 213 drives the upper cutter 211 to move downward to cooperate with the lower cutter 212 to cut the fabric.

[0054] The material distribution assembly 22 comprises a first dragging assembly 221 and a second dragging assembly 222. The first dragging assembly 221 is arranged at the lower end of the material conveying direction, and comprises a first clamping device 2211 and a fourth driving device 2212 for driving the first clamping device 2211 to move. The first clamping device 2211 clamps the cloth and drags the cloth to move under the driving of the fourth driving device 2212, so as to facilitate the cutting of the cloth. The first clamping device 2211 can be a clamping jaw, which can be integral and clamp the end of the cloth as a whole. Alternatively, the clamping jaw can be arranged at least at two positions and clamp the two sides of the end of the cloth, so that the cloth remains in a neat state when the first dragging assembly 221 drags the cloth to move.

[0055] The second dragging assembly 222 is arranged at the side of the material conveying direction, and comprises a second clamping device 2221 and a fifth driving device 2222 for driving the second clamping device 2221 to move. The second clamping device 2221 clamps the towel blank and is conveyed to the hemming assembly under the driving of the fifth driving device 2222. The second clamping device 2221 can be a clamping jaw, a suction disc group or other devices capable of picking up the towel blank. The conveying direction of the second dragging assembly 222 to the towel blank is perpendicular to the conveying direction of the first dragging assembly 221 to the cloth.

The ultrasonic generating device 322 and the knife head assembly 323 are arranged on the first bracket 321, and the first bracket 321 is connected with a first driving device 324. The first driving device 324 can drive the first bracket 321 to move synchronously with the conveying of the towel blank.

[0058] The upper end of the ultrasonic generating device 322 is connected with a knife seat 325; the knife head assembly 323 comprises a knife head 326 and a second driving device 327 capable of driving the knife head 326 to move downward to abut against the knife seat 325. During cutting, the second driving device 327 drives the knife head 326 to move downward to abut against the thread end to the knife seat 325 to realize cutting, at the same time, the first driving device 324 drives the ultrasonic generating device 322 and the knife head 326 assembly 323 to move synchronously with the towel blank through the first support 321, and the heat generated by the ultrasonic generating device 322 is transferred to the knife seat 325, and the heat generated by the high-frequency vibration of the knife head 326 assembly 323 is completed to realize the pressure maintaining of the thread end. It should be noted that the ultrasonic generating device 322 is connected with the knife seat 325, and the heat generated by the ultrasonic generating device 322 is transferred to the knife seat 325; during cutting and pressure maintaining, the knife seat 325 is driven by the ultrasonic generating device 322 to generate high-frequency vibration, so that high-frequency vibration also occurs between the knife seat 325 and the knife head 326, and heat is also generated, which is the two main sources of heat during pressure maintaining. The temperature during pressure maintaining is far lower than the melting temperature of the thread end cut by melting, but the cut thread end can be melted to a certain extent through a period of pressure maintaining, so that black spots or hard blocks are not generated, and the cut thread end is more neat, and scattering at the sewing and hemming position is avoided.

[0059] The hemming assembly 31 is provided with two symmetrical groups to realize simultaneous hemming of both sides of the towel blank. The hemming assembly 31 comprises a second transmission assembly 311 and a hemming device (not shown in the figure), and the hemming device completes the hemming sewing while the towel blank is conveyed by the second transmission assembly 311.

[0060] As shown in FIGS. 10-12, the second transmission assembly 311 comprises a carrier plate 3111, a first conveying belt 3112 and a second conveying belt 3113 arranged side by side with the first conveying belt 3112, and the towel blank can move on the carrier plate 3111 under the drive of the first conveying belt 3112 and the second conveying belt 3113. The carrier plate 3111 comprises a first conveying area 3111a and a second conveying area 3111b, and the second conveying area 3111b is provided with a first notch 3111c and a second notch, and the hemming device completes the hemming sewing of the towel blank at the first notch 3111c. The cutting assembly 32 completes the cutting and pressure maintaining of the thread end at the second notch 3111d. The lower end surface of the first conveying belt 3112 is parallel to the carrier plate 3111, and the first conveying belt 3112 is arranged directly above the first conveying area 3111a; the lower end surface of the second conveying belt 3113 is parallel to the carrier plate 3111, the second conveying belt 3113 is arranged directly above the second conveying area 3111b, and the second conveying belt 3113 is arranged between the first notch 3111c and the second notch 3111d.
