The card level sensing device is directly related to the level of the control system. The structure of the double twisting unit of the double twisting machine mainly includes the spindle braking device, the spindle part of the double twisting machine, the yarn winding device, and the special device of the double twisting unit. 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). 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. In the card sliver linear density sensor as an example, mechanical types of electrical, optical, capacitive, isotopic type, acoustic, inductive, pneumatic, microwave type, and other sensing devices can be used, but for various reasons, mostly mechanical guide. Therefore, the development of new sensors is of great significance.
Orientation sensor is a frequency, digital, integrated, complex and intelligent. When choosing different sensors, the matching with other controllers should be considered. For example, on the carding machine, the online education of the USTER P-type sensor network is used to continuously measure the sliver count variation, sliver unevenness and various Spectrogram, the Uster sliver data processing device matched with the FP sensor technology transmits the above model parameter analysis and data to the Huiji controller, so that the Huiji controller can make continuous corrections in a timely manner. Carding machine guide belt The ring guide belt used for printing is an important part of the screen printing machine.
Plays the role of lotus conveying fabrics and printed pads. It is required to have good elasticity, abrasion resistance, dye resistance, oil resistance, oil resistance, bending resistance, no elongation, no deformation, uniform thickness, stable size, accurate transportation, and ensure printing quality. The yarn guide belt of the carding machine is made of fabric as the core, and Mary is covered with wear-resistant rubber (lin, neoprene).
Foreign companies such as Japan's Maruyama Industries and West Germany have been able to produce K-belts that are 3 meters wide and 80 meters long. In the late 1970s, in order to manufacture dimensionally stable salvage guide belts, the rotary screen printing machine carried out a major transformation of the structure of the guide belt, with two layers of glass fiber filaments (80) embedded between the fabric layers of the guide belt. The stability of the structure is improved to prevent elongation and deformation (see Figure 2-20).
