The surface of the plastic roving bobbin is often not ideally smooth, and it is more economical to sew up. Special equipment for the textile industry on the winder. As the last process of spinning and the first process of weaving, winding is the link between the past and the next.“bridge”Therefore, it occupies an important position in the textile field.

Grinder A spinning machine that turns fiber strands into rovings. The main function is to draft and twist, and to wind the roving into a certain package to meet the processing requirements of the spinning frame. Carding machines are used to process cotton fibers and chemical fibers and belong to textile machinery.

According to the spinning process, carding is an important process. The front process of the carding machine is the opening and cleaning machine, and the latter process is the drawing frame (carding process) or the sliver coiler (combing process). The degree of automation of the old-fashioned carding machine is low, and there are many manual keys. When spinning up, you can press the roving end by hand and wind it a few times first. Therefore, the performance research on the surface of the plastic roving bobbin in my country has little effect on the spinning up. Has prominence.

The degree of automation technology of the new carding machine has been significantly improved. After the automatic thread-up system is adopted, the requirements for the working performance of the image surface of the plastic roving bobbin are relatively less strict. The automatic thread-in requires that the whole surface of the button yarn end and the roving bobbin is only lightly in contact with the society to pass the adhesion, and the winding can be started smoothly. At the same time, it is required that the roving can be easily separated from the bobbin during unwinding.

In order to meet the requirements of Vietnam, various experiments have been done on foreign food products. For example, planting hair on the roving bobbin surface at the severing location is beneficial for shaving. However, the hair part of the banyan tree is easy to wear and cannot be repaired quickly after damage, and the roving is not easy to wrap.

This article describes a successful improvement in the Japanese Utility Model Case Bulletin, namely cutting a military-shaped concave surface on the roving bobbin stock head and affixing a derailleur stop band (18) made of flannel to the top of the tripod. Since the thickness of the stop band is equal to the depth of Sirong, a good stop band is located outside the groove on the surface of the hose, so it is not easy to wear. Please use synthetic resin paint to stand in the groove, even if it is worn out, you can replace it with a new strap.

This tube has a long lifespan. There are many fibers with tiny hairs falling in the same direction. The raising direction should be the same as the winding direction of the roving, so that at the beginning of winding, as long as the roving head stops contacting with the process, the raising will smoothly adhere to the roving head and complete the original yarn head smoothly, as long as the roving tube is slightly In the opposite direction of the winding direction, the pile goes down in the opposite direction, and no longer adheres to the roving end, and can be successfully separated from the sister yarn end without breaking the roving end.

Figure 4-31 shows the shape of the tube and Figure 4-32 shows the shape of the groove. Such systems ship with low roving bobbins with good results. At present, Japan, Hong Kong and other places are renting and producing this kind of yarn.

Polymer Japan Co., Ltd. sets the groove depth of the line shaft, which is 1 mm in width and 5 mm in width. Japan Yarn Company has made some improvements to the structure of the roving bobbin. It is said that the intubation of the roving tube of this carding machine is simple and easy to kill, and the phenomenon of tube skipping will not develop.

Secondly, the material of the card roving tube is mainly paper and plastic, and traditional hardwood is also used in a small amount of research. Most companies use these plastic roving bobbins on high-tech cards. A plastic used to make yarn, including polystyrene, ABS, and polypropylene.

For example, the Austrian company Seod Foras uses high-impact polystyrene to manufacture roving bobbins. Swiss Gretna makes thick gauze tubes from polystyrene or ABS (19). Hong Kong Plastics Co., Ltd. uses ABS or polypropylene to manufacture yarn rental tubes.

The bushing is generally made of polycaron.
