Seven-axis cotton spinning roving frame

Abstract

The invention discloses a seven-axis cotton spinning roving frame. The seven-axis cotton spinning roving frame comprises four pressing rollers, and further comprises a flyer, a winding unit, a keel, four roller members and seven driving members; the seven driving members comprise the first driving member, the second driving member, the third driving member, the fourth driving member, the fifth driving member, the sixth driving member and the seventh driving member, and the first driving member, the second driving member, the third driving member and the fourth driving member are used for driving the roller members matched with the first driving member, the second driving member, the third driving member and the fourth driving member to move respectively, so that the draft multiple of the seven-axis cotton spinning roving frame is increased; the fifth driving member is used for driving the flyer to move; the sixth driving member is used for driving the winding unit to move; the seventhdriving member is used for driving the keel to lift and fall. According to the seven-axis cotton spinning roving frame, independent shaft drive is adopted, the defect that the draft multiple of a traditional roving machine is limited by the number of teeth of all draft gears and cannot be randomly adjusted is overcome through independent shaft drive, the draft multiple can be adjusted steplessly,and the precision is increased to 0.01.

Description

technical field [0001] The invention relates to the technical field of roving frames, in particular to a seven-axis cotton spinning roving frame. Background technique [0002] A roving frame is a spinning machine that turns fiber strips into rovings. The main function of the roving frame is drafting and twisting, and winding the roving into a certain package to meet the processing requirements of the spinning frame; the existing basic seven-axis cotton spinning roving frame is generally driven by three motors or four motors, and the total draft Both the drafting zone and the post-drafting zone are driven by mechanical gears, and the process wheels need to be changed in real time according to the requirements of the spinning process. The operation is extremely troublesome, resulting in low textile efficiency and seriously affecting the economic benefits of the textile industry. [0003] In order to solve the above problems, it is urgent to invent a new structure of six-axis ...
