The function of the card forming research institution is to make the bobbin move up and down with the dragon tendons and shorten the movement of the students to make the roving package in the form of a conical shape. 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. 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. 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.
The main contents of the development of this organization include lifting control device, forming technology device and so on. (1) Lift the device, the upper LONG, balance the counterweight, lift the sleeves, change the composition of the round window and other parts through the chain card lifting device. As shown in Figure 5-20, the speed change system of the lower iron gun is transmitted to 18Z, 29Z, 32Z. 32Z are two electronic reversing control gears, which are connected together by using a sleeve, the looper is on the shaft, and the sleeve arrow is forming Under the action of the fork of the technical device, the two 32Zs are alternately connected with the 32Z umbrella window wheel, so that the vertical uranium and the lifting input are rotated in positive and negative directions, and the alternating is repeated.
The side lying card lift sprockets are fixedly mounted and are moved up and down by a chain driven by a lift rod, Aberdeen. Lift lever P 5-17 as shown. , (A is the fulcrum, the other end of the bracket is long.
The lift motion is completed when the lift lever of the upper LONG is used for forward lift input and reverse rotation. In order to lighten the load and reduce power consumption, suspend the counterweight in the corresponding direction of the lifting rod symbol. When the upper dragon tendon rises, the heavy building descends, and the heavy hammer is used to support the upper dragon tendon and help the upper dragon tendon to rise.
At this time, the hammer rises, the painting surges the weight balance down steadily for a long time, and avoids the result; and the rib is caused by a sharp drop in mechanical vibration and damage. Chain lifting device is used to raise the upper dragon tendon, which can reach the required high level position, and the lower dragon tendon can be easily approached when it is lowered, which creates economic conditions for increasing the development of the highest height of the yarn roll.
