Problems solved by technology

[0003] However, in the actual use process, it is found that when the mounting part of the pressure roller is deformed and bent at a certain angle, the adjustment piece will also be deformed, and the adjustment piece will change its original horizontal state, forming a certain angle with the original horizontal state. At this time, torque will be generated on the upper and lower limit structures of the gasket and the bolt, which will affect the normal use of the bolt after a long time of work, and even cause breakage

Embodiment

[0021] Embodiment: a kind of rotor pinch wheel adjustment mechanism applied on air spinning, such as Figure 1-4 As shown, it includes a pressure wheel mounting plate 1, an adjustment piece 2, and an adjusting bolt assembly, wherein the pressure wheel mounting plate 1 is provided with a U-shaped through hole 11 that opens outward (shown to the right in the figure), so that the U-shaped through hole 11. An overhanging pressure roller installation part 12 is formed in the inner cavity, and the pressure roller installation part 12 can be bent and deformed at a certain angle under the action of a certain force.

[0022] In this embodiment, as a preference, both sides of the U-shaped through-hole 11 are extended to the outside with relief openings 15, so that the part of the pressure wheel mounting plate 1 located outside the U-shaped through-hole 11 is more easily deformed under force, reducing the pressure. The amount of force required for small angle adjustments.

Abstract

The invention discloses a rotor pressing wheel adjusting mechanism applied to rotor spinning. The rotor pressing wheel adjusting mechanism comprises a pressing wheel mounting plate, an adjusting pieceand an adjusting bolt assembly, wherein a first adjusting hole is formed in the pressing wheel mounting plate; a second adjusting hole corresponding to the first adjusting hole is formed in the adjusting piece; the adjusting bolt assembly comprises an adjusting bolt, an upper gasket and a lower gasket; a spherical groove and a spherical bulge are correspondingly formed in the upper surface and the lower surface of the adjusting piece correspondingly; and the lower surface of the upper gasket and the upper surface of the lower gasket are spherical surfaces and are matched with the spherical groove and the spherical bulge correspondingly. When an adjusting part of the adjusting piece deviates from an original horizontal position due to deformation, the adjusting piece can be automatically corrected in the transverse direction, and torsion generated by the adjusting piece to a whole bracket and the adjusting bolt is eliminated or reduced, so that the service life of the mechanism is prolonged and normal operation of the mechanism is guaranteed.

Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to a rotor pressure roller adjustment mechanism used in air spinning. Background technique [0002] The rotor pinch wheel is one of the components of the air spinning machine, and its angle usually needs to be adjusted through a specific adjustment mechanism. The current adjustment mechanism, such as a Chinese invention patent previously applied by the applicant: a rotor spinning machine pressure wheel adjustment mechanism (CN205669087U), including a mounting plate and an angle adjustment piece, which is set on the mounting plate in a cantilevered shape The pressure roller installation part of the rotor can be bent at a certain angle under the action of a certain force. When installing, the pressure roller bearing of the rotor pressure roller is installed on the pressure roller installation part and the adjustment piece. By changing the other adjustment piece The distance...
