Referring to fig. 7-8, the cutting device 5 includes two lower pressing plates 57 and two portal frames 51, the two portal frames 51 are provided, the lower ends of the horizontal portions of the two portal frames 51 are fixedly provided with electric telescopic columns 52, the lower ends of the two electric telescopic columns 52 are fixedly provided with a horizontal plate 53 together, the middle part of the lower end of the horizontal plate 53 is fixedly provided with four cutters 55 corresponding to the wind-up roll 27 one by one, the front part and the rear part of the lower end of the horizontal plate 53 are symmetrically and fixedly provided with two buffer assemblies 54, the lower ends of the two buffer assemblies 54 positioned in front and the two buffer assemblies 54 positioned behind are fixedly provided with an upper pressing plate 56 together, the lower pressing plates 57 are provided with two lower pressing plates 56 respectively and positioned under the two upper pressing plates 56, the two lower pressing plates 57 are fixedly arranged at the upper end of the mounting base 4, and the cutting seam 8 is positioned under a gap between the two lower pressing plates 57; the lower ends of the two upper pressing plates 56 are fixedly connected with four pressing blocks 59, the upper ends of the two lower pressing plates 57 are provided with pressing grooves 58 corresponding to the four pressing blocks 59, and the positions of the four pressing grooves 58 and the positions of the four pressing blocks 59 correspond to the positions of the four winding rollers 27 one by one.

It should be noted that the two slits 8 are located right below the gap between the two lower pressing plates 57, the gap between the two upper pressing plates 56 is located right above the gap between the two lower pressing plates 57, and the cutter 55 is located right above the slit 8;

the buffer assembly 54 includes a mounting sleeve 541 and a buffer plate 544, the mounting sleeve 541 is fixedly mounted at the lower end of the horizontal plate 53, a rectangular groove 542 is formed in the middle of the lower end of the mounting sleeve 541, the buffer plate 544 is fixedly mounted at the upper end of the upper press plate 56, and the upper end of the buffer plate 544 extends into the rectangular groove 542 and is fixedly mounted with a plurality of buffer springs 543 together between the top wall thereof.

Therefore, in the actual working process, when needing to cut off the polyester yarns, start the electric telescopic column 52, make the horizontal plate 53 descend, and then make two top boards 56 move down, when the top board 56 hugs closely the holding down plate 57, briquetting 59 embedding indent 58 compresses tightly the polyester yarns this moment, along with the continuation decline of horizontal plate 53, cutter 55 descends thereupon, utilize buffer spring 543's elastic force effect, make two top boards 56 continue respectively to compress tightly two holding down plates 57, then utilize cutter 55 to cut off the polyester yarns, then can avoid cutting off the easy winding of polyester yarns resilience in-process, need not artificial manual carding, and the work efficiency is improved.

It should be noted that, in the present invention, an electric control switch matched with the servo motor 23 and the electric telescopic column 52 is arranged in the electric control box 7, and the electric control box 7 can effectively control the electric control switch, and the electric control box 7 is electrically connected with 220V commercial power to supply power to the whole equipment.

The working principle of the invention is as follows:

before use: the polyester yarn is wound around a roller (not shown in the figure), passes through the pressing groove 58, and is sequentially wound on the lower part of the second guide wheel 63 and the upper part of the first guide wheel 38 and fixedly connected with the winding roller 27;

when rolling is carried out: the servo motor 23 is started, after the servo motor 23 works, the servo motor can be matched with the two shaft rods 24, the two first connecting rods 25, the second connecting rod 26 and the fastening piece 29, and the two winding rollers 27 on the outer surfaces of the two first connecting rods 25 rotate, so that the purpose of winding the polyester yarns is achieved;

when cutting off the polyester yarn: the electric telescopic column 52 is started, the horizontal plate 53 descends, the two upper pressing plates 56 move downwards, when the upper pressing plates 56 cling to the lower pressing plates 57, the pressing blocks 59 are embedded into the pressing grooves 58 to press the polyester yarns tightly, the cutter 55 descends along with the continuous descending of the horizontal plate 53, the two upper pressing plates 56 respectively continue to press the two lower pressing plates 57 tightly by utilizing the elastic force of the buffer springs 543, and then the polyester yarns are cut off by utilizing the cutter 55;

when the wind-up roll 27 is replaced: the two fixing sleeves 291 are pressed towards the middle to contract the first spiral spring 293 and the telescopic rod 292, and then the two fixing sleeves 291 are removed from the joint between the two first connecting rods 25 and the two second connecting rods 26, so that the fastening member 29 and the second connecting rods 26 can be taken out, the wind-up roll 27 and the fixing tube 28 can be taken out in sequence, and the wind-up roll 27 can be replaced conveniently.

The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
