The principle of the locking mechanism of the quilt production line The locking mechanism of the quilt production line is set up for the pressurization and release of the cradle. 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 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.
According to the requirements of the production management practice of using the quilt production line, the personnel of the locking mechanism must be able to meet the following three points: first, the operation of pressure and release by students is simple, convenient and labor-saving; the second is the positioning of the cradle after the pressure is relieved. From a technical point of view, it is necessary to facilitate self-maintenance and operation. The third is to reduce the size of the cradle shield as much as possible, which is convenient for changing and renting yarn and doing clean development work. Usually we use the four-bar linkage company as the locking mechanism. Now take the SF65-1 cradle (Fig. 3-27) and the TF-18 cradle (Fig. 3-29) as examples to illustrate the principle of this locking mechanism.
(1) SF65-1 spring pressure rocker locking mechanism: SF65-1 rocker is shown in Figure 3-27, and the schematic diagram of the mechanism can be shown in Figure 3-28. The rocker body (a), the handle (seed b), the locking part (rod d) and the rocker seat (represented by A, D chain brackets) respectively constitute three movable rods and one fixed rod of the four linkage mechanisms. Of the three active children, a, b are a shaker that revolves around A, D, and b is a continuous seed that can be flat.
The locking function of the quilt production line is based on the process of the quilt stick from the unloaded state to the pressurized state, after passing through the dead point (b and d become straight), the movement direction of the hand is opposite to the shaking group, they treat each other and lock on the upper surface of the rocker body. After locking, the connecting rods cannot move relative to each other, and the entire rocker body is integrated and kept under pressure. Lift the handle, make the b and d rods go over the dead point in opposite directions, move in the same direction through the handle and the rocker body, and then shake the frame to release the lock and enter the unloading state.
In Figure 3-28, the direction of movement of the group is represented by the cradle-to-spring reaction force, extending line b adjacent to the intersection of AB and DC is the instantaneous heart rate Xuan. Forced to ease when the orientation of the handle is in the same direction. Movement of the following trending seeds: .
