1. Phenomenon Due to careless operation, the cylinder head pin is suddenly and severely damaged. Some cylinder heads are crushed or broken by hooks with the tightest rows of pliers. Comb broken, etc. 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. 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. During the spinning process of the spinning frame, the semi-finished roving or sliver is drafted, twisted, and wound into a spinning machine. The combed sliver and the needle-carding machine combine the sliver, the needle row is drafted to improve the sliver structure, and the roving is further spun into spun yarn on the ring spinning frame, which is the main spinning machine. After combing Xinjinlong suddenly and severely blocked, the jaw lip is usually tied with wool, and the clarity of the cotton girl suddenly deteriorates significantly. In severe cases, it will stop automatically, and the signal light will flash by.
2. Analysis of the reasons 1. When changing the roll and reeling the head, the operation technical regulations are not followed, especially for the convenience of the drawing, the roll head and tail do not need to be organized and managed loosely, but to grab and pull hastily, causing small rolls If the foundation is thick and folded seriously, the load of Xinjinlong comb needles will increase, and the most tight rows of comb needles will be crushed. 2. If you do not pay attention to the car after cleaning the card, the latch of the broom chicken brown bucket lid is withdrawn, so that the upper connecting plate winds the semi-circular money falling down, causing the contact between the combed Xinjinlong and the semi-circular cassia chain plate, which greatly Part of the barrel is mechanically jammed. 3. When putting out Xinjinlong intarsia in front of the car or using a Chinese chrysanthemum broom for cleaning management after the car time, accidentally rolling a bamboo basket or chrysanthemum broom into Xinjinlong, forming a long vertical broken needle for Xinjinlong.
Three, preventive measures 1. The plug is required to strictly implement the winding head“even, accurate, even”Operators (that is, the winding tail is pulled and combed smoothly, the lap length conforms to the specification, and the cotton mesh joint is clear and uniform) to ensure the quality of the joint. 2. When you're doing cleaning, you have to concentrate.
Inlay and clean the narrow part of the elbow after the cylinder, be sure to wait until the car is parked. 3. When doing cleaning management work, you must learn and implement the method of light support and frequent wiping, and can be combined at any time for inspection to prevent the loosening of loose and easy parts such as pins and screws. 4. Handling Suggestions 1. For serious damage, it should be used as accident data for construction site management analysis, so as to attract students' attention in the future.
2. The damage of the comb needle cylinder lighter can be repaired by the triangular stone sleeve. When the cylinder is seriously damaged, the jig according to the cylinder should be replaced at the same time to grind the rim flange and recalibrate the table of each quasi cylinder. 3. If the wind semi-circular cover is broken by rolling dumplings, it should be removed again to cover the entire wind bucket, so as not to touch the Xinjinlong comb needle. At the same time, apply emery cloth sanding to the places where the hairs are combed by the needles to prevent the airflow from being affected by the flowers.
4. In order to prevent the bolts of the air bucket cover from loosening and running vibration during cleaning, a safety pin can be installed behind the air bucket bolts.
