The twisting mechanism of the quilt production line is mainly composed of the main shaft, the main shaft wing, the chain tube and the chain foot oil cup. 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. 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.
(1) The quilt production line spindle quilt round scribing mast provides high quality made of steel, its diameter is 19 ~ 22 mm, the length of the rod is 700-1000 mm, its schematic diagram 7-11. Its function is to support and cooperate with the flyer to drive the rotation to twist the yarn. The lower end of the awl is supported by the ingot foot oil cup fixed on the lower dragon bar, and the middle part is supported by the plated tube fixed on the upper dragon bar. The support of the mirror enables the awl to rotate continuously and stably.
There is a groove at the top of the chain, and the flyer pin on the flyer is inserted into a groove, so that the flyer can rotate synchronously with the mirror. The mirror and the lower part are fixed with a spindle foot screw processing gear, and the mirror is rotated by analyzing the gear mechanical transmission control system. (2) The quilt production line flyer is typically made of mild steel quality quilt wire flyer, and the new high-speed flyer is made of aluminum Made of alloy material. It extrudes four parts from the sleeve, the solid arm, the arm and the hollow fingers, in the ingot shown in Figures 7-12.
In addition to the yarn effect on it is twisting, but also guiding on spools and rovings. 1. There are small holes (ie top holes) at the top of the spindle casing, and side holes on the front, rear, left, and right sides. The rovings penetrate through the top holes and enter a hollow arm from the side holes. The hollow arm is required and the inner wall surface is smooth, and there are certain inclined slits on the outer side, which is convenient for yarn drawing and can prevent the roving from flying out due to centrifugal force.
Solid arms play a role in balancing development. 2. The palm pressing is made of hollow arms of upper and lower ring sleeves, which can rotate around the hollow arms at a certain angle; the vertical part of the palm pressing rod is slightly heavier than the horizontal part of the palm pressing leaf. The centrifugal force decreases, so as the winding diameter increases, the pressure on the bobbin decreases, so that the inner winding of the bobbin is tight and the outer winding is loose, thereby preventing the two ends of the inner roving from being squeezed.
But at the same time, the inner layer will be more flattened, and the outer layer will be less flattened, which will affect the winding tension. image 3. In Sichuan, the openings at both ends of the chain depend on the diameter of the package.
The high-speed, long-arm, and large-opening main shaft airfoils are subjected to radial deformation caused by centrifugal force, and the two arms extend outward, which may lead to collision of adjacent main shafts. In recent years, with the increase in package size and the rising spindle speed, the conventional ingot end support mode can no longer meet the demand. Now? In the structure of the flyer, it has gradually developed into a suspension (chain) structure.
The suspension spindle is installed on the upper long, so the small chain wing itself vibrates. At the same time, because they are not disconnected from the flyer doffing chain wing itself, it does not affect the operation of the size of the weight, and the cross-sectional size can be appropriately increased to accommodate the high-speed rotation and deceleration of the outer sheet deforming weapon. In addition, since the chain is installed on the lower side rib, blow-by air flow will be suppressed, thereby reducing the rental, floating head.
