Description

TECHNICAL FIELD

[0001] The utility model belongs to textile equipment technical field especially, it is a kind of electronic forming device for rotor spinning machine. BACKGROUND

[0002] In the operation process of rotor spinning machine, electronic forming device plays a key role. It is mainly applied to rotor spinning machine, the purpose is to guide yarn to reciprocate in specific area, to realize the effective control to yarn winding. Its working principle is to control the reciprocating speed of guide bar and the rotating speed of winding roller accurately, then different winding angles and densities can be obtained. Different winding angles and densities have important influence on the quality and performance of yarn, for example, suitable winding angle can make yarn distribute more evenly in winding process, avoid uneven situation, and suitable density can guarantee the compactness of yarn winding, improve the overall stability and subsequent processing performance of yarn.

[0003] However, the same action device commonly used on rotor spinning machine at present has many problems. Many devices adopt cam mechanism to drive guide bar to move transversely. Cam mechanism is relatively common in mechanical transmission, but in this application scenario, its structure is often extremely complex. The contour curve design of cam needs accurate calculation to meet the specific motion trajectory requirements of guide bar, which increases the difficulty of design. Moreover, in the manufacturing process, the machining precision of cam is high, and the manufacturing process is complex, which needs high-precision machining equipment and professional technical personnel, which not only leads to great manufacturing difficulty, but also makes the manufacturing cost high.

[0004] In addition, part of the device lacks guide rail. In the reciprocating movement of guide bar, guide rail plays a key stabilizing role. Without guide rail, guide bar is easily disturbed by various external forces when moving, such as yarn tension change, mechanical vibration, etc., so that jumping phenomenon occurs. The jumping of guide bar not only affects the normal guidance of yarn, causes yarn to appear winding, knotting and other problems, reduces yarn quality, but also easily causes device failure, increases equipment maintenance frequency and maintenance cost.

[0005] Some devices have large overall size, and the space of rotor spinning machine head is relatively limited. Larger device size makes its installation and disassembly process on rotor spinning machine extremely difficult. When installing, a lot of time and effort is needed to adjust the position of device to ensure the cooperation accuracy with other parts; when disassembling, due to space limitation, the operation space is small, and tools are difficult to use, which increases the difficulty of disassembly. In addition, this inconvenient installation and disassembly process also seriously affects the subsequent maintenance work. When repairing, maintenance personnel are difficult to quickly and conveniently check and replace parts of device, which prolongs the downtime of equipment and reduces production efficiency.

[0006] In view of the above, in order to solve the problems existing in the same action device of the existing rotor spinning machine, it is particularly urgent to develop a new electronic forming device for the rotor spinning machine. Content of the utility model
