Electric centralized selection of electrical control cabinet centralized control cabinet can effectively be cleared flower, carding and dust partially organically combined into a system, which is characterized by: centralized control circuit is simple, using a programmable controller PLC extension technology , automatic control technology and variable frequency technology, fully embodies the modern high-tech applications in the Blowroom machine, centralized control cabinet compact, structured, panel indicates visual image, easy to operate. Open carding machine must be configured with the development of carding machine carding machine is one of the key components of blowing-carding machine, in the digestion and absorption of the German company DK715 Trützschler type, DK740 carding machine on order and supporting our existing Autoleveller, while absorbing the Rieter C4 carding machine roller ladder testing organization, to design the FA221 type carding machine, in April 1994 through the ministerial level in Guangdong Kaiping produce identification, the machine has the following characteristics: ① design high output, each actual output of up to 35 ~ 50Kg / h, the maximum design speed of Article 300m / min, 25 m overall unevenness (CV value) of 1.86%, total draft multiples of 60 to 130, hooking speed 10 ~ 50m / min. ② processing and installation of high accuracy. The frame is welded steel structure, a relatively high degree of parallel of the components, smooth operation and good, long-term operation without distortion. The whole machine cylinder class all parts are made of high speed steel roll Park welding, high precision, tin Lyngdorf imported special boring, turning, grinding machining, beating about 0.01mm, rigid, and is conducive to strong tight gauge carding. ③ feed roller diameter increased and the use of coated blade structure, strengthening the cotton portion of the cotton layer gripping ability to improve the opening, carding and cleaning effect licker area. ④ cylinder cover and reverse movement activities make fibers and clean the cylinder outlet cover contacts conducive to the discharge fuzz, cover with small heel-toe poor, improve carding effect. ⑤ package has bent pins on a large cloth roll continuous cleaning brush cover flowers, floral cover down after the admission of high-speed rotating cleaning roller peeling sucked by a continuous ventilation, better cleaning results. ⑥ adding auxiliary carding elements, such as pre-carding plate, dust knife, fixed cover, etc., for the liquidation of the cylinder area continuously, especially for removal of residual impurities and dust debris seeds have a significant effect. High quality metal clothing, metal card clothing is the heart of the Swiss Graf Cheng Textile plant using the company's R2525X0.5 and 0-4030X0.9 clothing and ST45 of flat clothing, such clothing have material quality, high precision punching teeth, heat treatment, long service life, tooth short, shallow, sharp, thin, dense and working angle and other characteristics, carding effect, can significantly improve the webs and sliver quality. ⑦ automatic suction noil, this device is one of the key means carding, FA221 carding machine has 11 suction points, continuous pumping, the car belly flowers and flower cover all collected both before and after the dust box On the machine wind turbine capacity 2500m3 / h or more, get off belly has intermittent blowing device, blowing smoke combined, vacuuming and miscellaneous noil good effect. The whole process card noil intermittent suction device, in order to take away all of the dust box sets card noil. ⑧ with complete safety device including: a, cylinder, licker speed can not be set lower than the cotton. b, fed cotton layer is too thick from the stop. c, thick cotton net output from the stop. d, carding cotton cotton box for failure from the stop. e, decapitated photoelectric since stopped. f, open security Achilles Heel from the stop. ⑨ with advanced electric control system aircraft electrical system can be connected to a variety of cotton tank electrical system, the whole machine is multi-motor drive system, in which the cotton layer feed, Astoria are DC motor speed control system, the rest of the transmission are AC induction motor, complete control in the programmable controller PIC Feeding, grooming, out of the production process. Run the delivery speed, draft ratio, can be quantified in front of the machine through a multi-turn potentiometer to adjust according to process requirements, the machine comes with a long clip ya Autoleveller by the microcontroller as the core of the computer processing system may be in control on the operation panel and display of process parameters, as well as the shift output counting down the cause of the malfunction and to be displayed on the panel. Development on the card at the same time has been improved in the electrical, mechanical, design a new hopper and FA221A FA177A new card, further improves the stability of the equipment and processes, making the process more reasonable effect. Which adapts more clear flower machine also made improvements and modifications.
