Novel rotor type open-end spinning machine

Abstract

The invention discloses a novel rotor type open-end spinning machine which not only can realize spinning at a high speed, but also can weave two different kinds of yarns simultaneously, and has the advantages of low noise, low energy consumption, high yield, good stability, low manufacturing cost, and the like. The novel rotor type open-end spinning machine is formed by connecting a left tail structure, a left middle spinning structure, a central control drive structure, a right middle spinning structure and a right tail structure in sequence, wherein the central control drive structure comprises a rotor motor, a central control drive base and slide block connectors; the slide block connectors are symmetrically fixed to the left end and the right end of the back of the central control drive base; an axis a, an axis b, an axis a' and an axis b' are fixed to the central control drive base; the axis a and the axis a' as well as the axis b and the axis b' are in a mirror symmetry relationship relative to the ridge line of the central control drive base; the axis a, the axis b, the axis a' and the axis b' are respectively provided with a dragon belt pulley and a flat-belt pulley, and the flat-belt pulleys arranged at the left side and the right side of the central control drive base are respectively connected with one rotor motor through a flat belt.

Description

technical field [0001] The invention relates to a novel rotor spinning machine, which belongs to the technical field of spinning machinery. Background technique [0002] The existing rotor spinning machine is composed of three major parts: the head drive structure, the middle spinning structure, and the tail structure. In order to increase output, the prior art all realizes by increasing the number of spindles of the middle section spinning structure to lengthen the complete machine. However, as far as the existing rotor spinning machine is concerned, the more the number of spindles, the higher the requirements for the radial runout of the connecting shafts in the middle section and the coaxiality between the shafts, which greatly increases the manufacturing cost and Difficulty in manufacturing; on the contrary, if the coaxiality is poor, the transmission stability will be poor, the spinning will be unstable, and the yarn drawing speed and feeding speed will be difficult to...

Problems solved by technology

However, as far as the existing rotor spinning machine is concerned, the more the number of spindles, the higher the requirements for the radial runout of the connecting shafts in the middle section and the coaxiality between the shafts, which greatly increases the manufacturing cost and Difficulty in manufacturing; on the contrary, if the coaxiality is poor, the transmission stability will be poor, the spinning will be unstable, and the yarn drawing speed and feeding speed will be difficult to increase, which will affect the increase in output; in addition, in order to ensure normal spinning under multiple spindles, it must be required The process fan maintains sufficient and stable negative pressure, which requires the power of the process fan to be increased, resulting in a lot of noise

The current rotor spinning machine processing technology can only reach a maximum of 320 spindles, and the rotor spinning machine field is facing a bottleneck that is difficult to break through

[0003] Moreover, existing rotor spinning machines can only weave one type of yarn at the same time. If multiple different types of yarns are to be spun, one has to wait for one type to be spun and then replace the next type, which has the disadvantages of long cycle time and tedious workload Defects; or reserve multiple rotor spinning machines, which has the defects of high cost and low utilization rate of equipment
