Description
Technical Field
The invention belongs to the field of spinning machines, and particularly relates to a symmetrical electronic drafting device of an ultra-long spinning frame.
Background
The overlength spinning frame is favorable to reducing the recruitment, reduces intensity of labour, and production efficiency improves, reduces area, reduces investment cost, and product quality is stable, and equipment degree of automation is high, the dependable performance. The super-long spinning frame effectively reduces the quality difference of machine tables among batches; meanwhile, due to the increase of the number of the ingots, the yarns with the same number are produced, the number of the used machine tables is reduced, and the quality difference of the machine tables among batches is effectively reduced. The increase of the number of spindles of each spinning frame means the reduction of the cost under the same output; the reduced number of machines reduces capital costs, capital and maintenance costs (space requirements, energy, air conditioning, etc.). Further cost savings can be achieved if the number of machines actually used in the preceding and following steps can also be reduced. The ultra-long spinning frame is provided with the fine spinning connection, so that the potential capability of the bobbin winder is improved, the spindle-by-spindle tracking of spinning quality can be realized, and labor is reduced. Therefore, the ultra-long spinning frame always becomes a development direction of the textile machinery.
The spun yarn overlong vehicle has the main problems that: the roller transmission route, electronic drafting synchronous control and the stress of the drafting components are balanced to ensure the consistency of the spinning conditions between sections and between spindles, thereby ensuring the consistency and stability of the yarn quality.
The traditional spinning frame adopts mechanical drafting, a main motor drives a spindle through a rolling disc on a main shaft, and the other end of the main motor drives a front roller, a middle roller and a rear roller through a series of gear transmissions (including a plurality of drafting conversion gears, twist conversion gears, rear zone drafting conversion gears and the like which are suitable for various spinning processes). When the spinning variety is changed, the machine needs to stop and change various changing gears. Because the roller transmission belongs to a slender shaft and the bearing capacity of the roller transmission is limited by the number of spindles, namely the length of the roller, the transmission mechanism is not suitable for a super-long vehicle, namely a spinning frame with spindles more than 1200.
The roller transmission of the ultra-long spinning frame is the preferred electronic drafting form, and an intermediate driving device is required to be added. Compared with the traditional spinning frame, the roller transmission is not driven by the main shaft any more, so that the transmission route of the whole spinning frame is simplified and more reasonable. The main disadvantage of the electronic drafting mode is high cost and uneconomical when being matched with a short spinning frame, but the disadvantage is weakened when being matched with an ultra-long spinning frame, and the advantages brought by the electronic drafting mode are fully embodied. The electronic drafting mode not only reduces or eliminates the work of manually replacing process gears, but also further expands the spinning range and variety and realizes stepless adjustment and accurate drafting.
The roller transmission route has various choices, and aims to balance the transmission torque and overcome the influence of the torsional vibration of the roller on the drafting. But different transmission routes also determine the overall mechanism layout of the main machine. There are two representative transmission routes currently on the market. It is easy to judge that both of these solutions have a disadvantage that the roller force of each section is not uniform.
