Mainly applicable to a medium (count) and coarse (count) yarn. 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). 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. 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.
Forming process of quilt production line 1. Place the knotted yarn parallel to the separator and skein. figure 2. Pull the joystick to rotate the screw hook about 90 degrees, push the yarn piece forward, and make the left and right winches cross into yarn.
3. The screw hook rotates 270, and the center adopts the blade and scissors linkage mechanism to begin to develop into a knot. 4. Rotate the helical hook 315 nearly two while the yarn is cut by the scissors (slightly advance the center of the blade). 5. Continue to pull the wrench to lift the tight knot hook, tighten the knotted end, and release the fingers to make the various parts system reset. The operation of the quilt production line requires the yarn to be knotted. The triangle speed is about 100mm.
The left-hand yarn holding point is about 30mm away from the left wall, and the right-hand holding point is about 70mm away from the right block. This operation is convenient and the knotting rate is high. The yarn triangle length on the high-speed banyan tube is the same as above, but the distance between the two walls is opposite.
(3) The use and storage of the quilt production line 1. Someone should use the knotting and be responsible for keeping it. 2. Use a small brush and clean the cotton dust inside. 3. Thorough cleaning once a week.
Fula, contact point of push core yarn, A series, inner sleeve (removal of fuel), neck bearing, bearing screw, friction between movable blade and fixed blade, weekly refueling, fuel, bi-tip. 4. Do not fall down in order to avoid damage to the parts during use. 1. Summarize the causes: (1) When the knot is tied, the wrench is used to pull the foot, so that the tight knot hook is not lifted, and the knot is loose; (2) The gap between the left-pushing yarn piece and the twisting piece is related to the number of yarn specials (counts). The ratio is improperly carried out, and it is too loose. (3) The elasticity of the spring blade is not suitable for the number of yarns (counts) made. When the tight hook is lifted up, the yarn structure can be pulled out from the spring blade prematurely, forming a loose (4) The sharp corners of the tight hook are worn, and the hook cannot be lifted during movement, which will also cause loose knots: (5) The spring is embedded with flying flowers through the middle of the blade, and the blade is not rolled tightly, which may easily lead to loose knots.
Maintenance method: Yarn push plate, flick of the piece, three taboos, tight connection between hooks with appropriate elasticity. Flick the loose-leaf, should adjust the flick piece and tighten the hook, the hook should be left for the play tight end piece stud cutter to erase, the play should twist the twist yarn piece and the sheet push the play? The cut off gap of the piece is too large, it should be adjusted . The knot is usually formed by proper drawing, and then a smooth knot is performed, and the two pieces of yarn twisted between the two yarns are elastically fit when the push plate slides.
Knot-shaped transverse detonation, no loose fat, smooth hand skinning. When enough lift hooks are tightly connected, the knots are preferably 2 mm or less tightly positioned on the inside of the hooks.
