Guide transversing mechanism in the existing textile machine comprises a traverse bar and the some thread-carriers that are loaded on this traverse bar, and each thread-carrier is corresponding to a spinning passage and work ingot position.Owing to be connected in corresponding two the spinning passages of feeding roller on the same reel cage, the guide rod that traverses is back and forth horizontal when mobile, be positioned at two feeding slivers of reel cage both sides, a sliver is close to the pressurized cradle center line, another root sliver then deviates from the center line of pressurized cradle, also just make the feeding jaw grasping force of pressurized cradle one side become big gradually, and the grasping force of opposite side jaw diminishes gradually, form both sides jaw grasping force cyclically-varying, it is more outstanding especially to seem under the situation that high draft heavily pressurizes.The unbalanced extremely of this jaw grasping force is unfavorable for the optimization of resultant yarn strip dry CV value and fibrous index, directly influences the raising of yarn quality level; The variation of jaw grasping force simultaneously also can cause the nonparallelism of upper leather roller counter extensioin roller to increase, and order further worsens the uniformity that the stretched yarn rule is done again.
The utility model content
At the above-mentioned deficiency of existing in prior technology, technical problem to be solved in the utility model provides a kind of spinning transversing mechanism with balanced feeding jaw grasping force, it can not only avoid feeding the formation of roller wearing and tearing groove, and respectively feeds jaw grasping force uniformity.
In order to solve the problems of the technologies described above, a kind of spinning transversing mechanism of the present utility model with balanced feeding jaw grasping force, comprise thread-carrier and the guide rod that traverses that thread-carrier is installed, the described guide rod that traverses has two and be arranged in parallel, be installed on respectively on two different guide rods that traverse with corresponding two thread-carriers of same epithelium posterius roller, these two guide rods that traverse are driven the reciprocal translation of direction of action by the drive unit that traverses.
After adopting said structure, owing to be installed on respectively on two different guide rods that traverse with corresponding two thread-carriers of same upper leather roller, and two guide rods that traverse are done the opposite reciprocal translation of direction.Two of same upper leather roller correspondence thread-carriers and sliver are in the effect of two different guide rods that traverse during spinning, respectively simultaneously near or deviate from the position of center line of pressurized cradle simultaneously, also be two feeding jaw grasping force application points of reel cage both sides remain equal length to the reel cage center line acting force arm.This just makes its feeding jaw of feeding sliver what position in office all keep the fixed grasping force that weighs.Roller is stable to the plus-pressure of sliver, has both very helped the raising of resultant yarn strip dry CV value, can effectively reduce resultant yarn filoplume again.Also owing to adopt said structure, the plus-pressure equilibrium of roller both sides avoids producing roller not parallel to roller, has guaranteed the correct position of roller nip, has also further stablized sliver bar evenness after the drawing-off.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is made further detailed explanation.
