The company was founded in 1998, a professional Fabric Recycling Machine Manufacturer in China.
The function of the card doffer is to transfer and collect the separated fibers on the card needle teeth to the doffer needle teeth, and then peel off into a brocade net through the peeling mechanism. 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. 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.
This card doffer cohesion and effect transfer the two surfaces of the fibers so that the mutual positional relationship between the needle doffer teeth cannot be used with the cylinder arrangement relationship to obtain its effect. Otherwise, not only does the doffer cylinder have to be above the surface speed, but also very thin layers of fibers can be transferred, which is less than the carding process required to bring the fibers together into a web with a certain strength. In order to improve the transfer rate of enterprises, the distance between Xinjinlong and Doffer is as small as about 0.125 mm (13 inches), which is the minimum distance for each work management organization of the carding machine.
In fact, the needle on the surface of the carding doffer and the Xinjinlong needle have been“roller”configuration. The utility model adopts deep serrations, the working angle is small, the gripping force and capacity of the doffer saw window to the fibers are improved, and the speed of the doffer is much lower than the speed of the cylinder, so that the doffer is transferred from the drum to the coagulation of the fibers. Production of cotton web craft. Obviously, the fiber layer on the surface of the card Xinjinlong could not have been“all“Transfer to the doffer pin tooth surface.
On a metal clothing carding machine, the measurement method of the amount of free fibers: while stopping the brocade and the flat plate, make a quick color mark on the sliver output from the large bell mouth, and collect the fibers of the output sliver (from The color scale is thinned from the beginning to the end) and the fly emblem, buckle the big bell mouth to the Xinjinlongdorf point length, weigh the remaining sliver fiber, and weigh the free fiber. The transfer rate affects the output of the machine. On the high-yield carding machine, the conveying speed must be increased. In order to output in time, the Xinjinlong is carded on the fiber to ensure the productivity of the carding machine and reduce the Xinjinlong merchant.
Due to the reasonable design of the doffer wire cloth, the doffer transmission rate is from more than 2~3% in the past to the current key level of 15~2O%. When the transfer rate is too high, the chances of fibers receiving knowledge carding and uniform mixing in the carding area of Xinjinlong flat plate will be excessively reduced, which will increase the cloudiness and uneven appearance of the cotton web. Therefore, when we are currently designing a high-yield combing machine, the maximum risk transfer rate between Xinjinlong and Daofu should be limited to less than 20%.
Due to the transfer rate to the cylinder side husband 20%. This means that most of the fibers are put back into the head combing area repeatedly and then mixed evenly with the blended fibers, which function. When the feeding cotton lap has a short segment thickening, the Xinjinlong needles do not immediately complete the transfer to the doffer through the fiber, but store the excess fiber cells in the needle window.
When the short pieces of cotton laps changed again, Xinjinlong released the fibers of their information storage, and transferred the supplementary function to Doffer. Therefore, an appropriate transfer rate can improve the unevenness of the sliver caused by the uneven size of the short segments of the cotton lap, while ensuring high yield. Doffer working diameter for ￠706mm (698mm bare).
On small silicon combs, the working diameter of the diff is correspondingly reduced toφ390mm (bare business isφ382mm).
