Description

Technical Field

[0001] The utility model relates to the field of elastic adjustment and compensation mechanisms for metal card clothing wrapping, in particular to an elastic adjustment and compensation mechanism for metal card clothing wrapping. Background Art

[0002] In the textile industry, before the spinning raw materials enter the combing process, the card clothing is usually tightly wound on the cylinder, doffer, working roller and other rollers. The metal card clothing wrapper is an indispensable device in the process of tightly winding the card clothing. In traditional equipment, the instability force of the card clothing can be buffered and eliminated in the lateral direction, but there is no device to eliminate the instability of the metal card clothing in the longitudinal direction, so as to promote the metal card clothing to be evenly wound on the roller surface, so as to achieve the purpose of improving the quality of the metal card clothing wound on the roller;

[0003] For example, patent CN206089910U discloses a metal card clothing wrapping arm, including a long arm, a short arm, an open linear bearing sleeve, and a wire-clamped elastic pressure plate frame, wherein the wire-clamped elastic pressure plate frame is arranged on the short arm, and an open linear bearing sleeve is arranged on one side of the long arm and the short arm, and the open linear bearing sleeve is movably arranged on a metal cross tube for installing the wrapping arm, and an inlet roller frame and an outlet roller frame are installed on the long arm, and a roller is installed on the roller frame;

[0004] Although the above patent uses a wire-clamped elastic pressure plate frame to flexibly control the tension of the wire-clamped sheet on the metal card clothing when it passes through, it effectively solves the tension balance problem during wrapping, ensures the flatness of the metal card clothing when it is wrapped on the cotton carding machine drum, and does not cause shaking to the wrapping arm when there is too much spacing when moving. However, this patent only buffers the tension in the lateral direction to prevent the metal card clothing from being broken by excessive lateral tension, and cannot solve the situation when the metal card clothing is subjected to longitudinal force. In other words, this patent eliminates the lateral force of the metal card clothing, but if the metal card clothing itself has longitudinal force, this patent cannot eliminate it. When there is longitudinal unstable force caused by the vibration of the metal card clothing itself, the metal card clothing will cause the winding force to be unstable due to the existence of the longitudinal force, and the metal card clothing cannot be tightly wrapped on the roller, resulting in unsatisfactory wrapping effect and quality assurance. Utility Model Content

[0005] The utility model aims to provide an elastic adjustment and compensation mechanism for metal card clothing wrapping, which solves the problem that the metal card clothing in the prior art will have unstable winding force due to the existence of longitudinal force, and the metal card clothing cannot be tightly wound onto the roller, thus resulting in unsatisfactory wrapping effect.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an elastic adjustment and compensation mechanism for metal card clothing wrapping, comprising a support frame, characterized in that a roller is rotatably connected inside the support frame, a slot is provided inside the support frame, a driving motor is fixedly connected to the bottom of the slot, a lead screw is fixedly connected to the output end of the driving motor, and a threaded block is threadedly connected to the lead screw;

[0007] The threaded block is provided with a connecting plate extending outward through the slot, and the upper end of the connecting plate is fixedly connected to a supporting seat.

[0008] As a further description of the above technical solution: a movable frame is arranged at the upper end of the support seat, and a guide wheel is rotatably connected inside the movable frame.

[0009] As a further description of the above technical solution: metal needle clothing is arranged on the guide wheel and the roller, and a first sliding groove is also opened inside the support frame.

[0010] As a further description of the above technical solution: a sliding rod is fixedly connected inside the first sliding groove, a first sliding block is slidably connected to the sliding rod, and an outer end of the first sliding block passes through the first sliding groove and is fixedly connected to the connecting plate.

[0011] As a further description of the above technical solution: a limiting groove is arranged inside the support seat, and a damping spring is fixedly connected to the inner bottom of the limiting groove.

[0012] As a further description of the above technical solution: the other end of the damping spring is fixedly connected to the limiting plate, and the other end of the limiting plate is fixedly connected to the movable frame.

[0013] As a further description of the above technical solution: second sliding grooves are opened at both ends of the inner side of the limiting groove, and second sliding blocks are fixedly connected to both ends of the limiting plate, and the second sliding blocks are slidably connected inside the second sliding grooves.

[0014] The utility model has the following beneficial effects:

[0015] 1. Compared with the prior art, the elastic adjustment and compensation mechanism for wrapping the metal card clothing can drive the connecting plate and the guide roller at the outer end to adjust the height by setting a driving motor, a lead screw and a threaded block. The tightness of the metal card clothing can be adjusted when the metal card clothing is transported, thereby ensuring the stability of the metal card clothing during transportation and effectively preventing it from being too loose or too tight. At the same time, a support seat, a movable frame and a damping spring are set at the lower end of the guide roller to achieve the effect of buffering and shock absorption, thereby eliminating the longitudinal unstable force.
