In order to meet the high production sliver, and need to ensure the quality of the card are equipped with automatic parking device. 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.
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. 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 FA203 type of card has six automatic stop processing means, i.e., thickness from stop to volume, barbed reel speed to decrease from stop, return to flow from stop, photoelectricity due to stop breaking bars, mechanical breakage from rod coiler station, distance Parking jams.
1. Self-stop for thick rolls In order to prevent the feeding of too thick cotton layer or the mixing of hard debris, etc., there is a penalty for self-stopping of thick rolls at the back of the machine. When the feeding cotton layer is too thick or mixed with hard debris, the cotton feeding roller is raised, and the two ends of the feeding roller are pressed and the screws on the lever make the micro-state switch technology of the self-stop device act to control the doffer and the cotton feeding stop. . 2. The licker-in speed is reduced from the stop deceleration, electronic speed switching operation, signal light.
After processing is complete, return to the licker-in speed setpoint or greater, and the signal light can be doffer driven. The cause of thorn reel deceleration is usually belt slack. 3. Automatic stop at flower When the stripping roller returns to flower, the return flower pushes the rocking plate to move, so that the moving network switch is normally closed, the fault time relay operates, and the doffer brakes.
At this time, the red signal light is on, open a safety cover, take out the back flower, and then open the doffer, the signal light is off. 4. The photoelectric self-stop of the broken bar is arranged on the ring bar, and a set of photoelectric self-stop device is configured. In normal operation, if there is a broken bar, the photoelectric will send a signal from the parking lot to control the driver to stop.
5. In the coiler, the broken bar is automatically stopped by the machine, and the pipe is automatically stopped by the blockage. There is a button switch on the small pressure roller of the coiler to control the cotton swab to automatically stop the inclined tube. There is also a mechanical contact to control the automatic stop of broken bars.
When six or more operations are stopped from the device, a light signal is transmitted on the machine.
