Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of knitting machines, and in particular to a belt adjustment frame of a circular knitting machine. Background Art
[0002] Circular knitting machines, scientifically known as circular weft knitting machines, have developed rapidly due to their multiple loop forming systems, high rotation speed, high output, fast pattern change, good fabric quality, fewer processes, and strong product adaptability. However, the pulley stability of existing knitting machines is poor during use, and the position of the pulley needs to be adjusted through a positioning mechanism composed of a draw rod, a nut, a spring, and a gear wheel. The pulley position is adjusted during the process of pulling the draw rod, and it is not easy to control the force for precise positioning during the process of pulling the draw rod. Utility Model Content
[0003] The utility model aims to solve the above problems and provide a belt adjusting frame for a circular knitting machine.
[0004] The technical solution of the present disclosure is achieved as follows:
[0005] The present invention discloses a belt adjustment frame of a circular knitting machine, comprising a fixed seat, an adjustment rod, a pulley movable part, a pulley, and a pulley fixing part, wherein the adjustment rod is fixedly mounted on a side of the fixed seat, a groove is provided on the adjustment rod, the pulley movable part is mounted on the adjustment rod, a pulley is mounted on the pulley movable part, and the pulley fixing part is fixedly mounted on the adjustment rod;
[0006] The pulley movable part includes a mounting seat, an adjusting screw, a guide rod and a limit block. The adjusting screw is movably mounted on the mounting seat, and the guide rod is fixedly mounted on the mounting seat. The limit block is provided with a threaded hole and an opening corresponding to the positions of the adjusting screw and the guide rod, and the threaded hole and the opening are respectively adapted to the adjusting screw and the guide rod. The limit block enables the limit block to move along the guide rod by cooperating with the thread of the adjusting screw. At the same time, the limit block and the mounting seat are respectively arranged at the upper and lower ends of the adjusting rod, and the adjusting screw and the guide rod are connected with the threaded hole and the opening through the groove body.
[0007] In the above technical solution, by rotating the adjusting screw, the limit block threadably connected to the adjusting screw will move up and down along the guide rod. When the limit block is separated from the mounting seat, it can move left and right along the groove body to adjust the position. The limit block and the mounting seat clamp the adjusting rod, thereby fixing the mounting seat and the pulley installed thereon.
[0008] In one embodiment, the pulley fixing member is fixedly mounted on the adjusting rod via a screw rod, and a pulley is mounted on the pulley fixing member.
[0009] In one embodiment, the diameter of the adjusting screw and the width of the guide rod are both smaller than the width of the groove body. When the limit block and the mounting seat are loosened by rotating the adjusting screw, they can move along the length direction of the groove body. In this technical solution, the movable part of the pulley can move along the length direction of the adjusting rod, which is convenient for adjusting the fixed pulley.
[0010] In one embodiment, the limit block and the mounting seat are respectively fitted with rubber gaskets on the upper and lower contact surfaces of the adjusting rod, which increases the friction when the limit block and the mounting seat are rotated by the adjusting screw to clamp the adjusting rod. At the same time, at least two holes are provided on the rubber gasket, which are adapted to the threaded hole and the opening for the adjusting screw and the guide rod to pass through. In this technical solution, the friction of the pulley movable part fixed on the adjusting rod is increased by adding rubber gaskets to the limit block and the mounting seat, thereby increasing the stability of the fixation and preventing loosening during long-term use.
[0011] In one embodiment, the adjusting screw is provided with an integrated limit plate, which is movably installed in the mounting seat to limit the position of the adjusting screw and rotate with the adjusting screw. In this technical solution, the adjusting screw is restricted in the mounting seat by the limit plate so that it can only rotate along the mounting seat to prevent it from falling off during the adjustment process.
[0012] In one embodiment, a pulley is installed on the mounting seat. In this technical solution, the pulley can move with the mounting seat to facilitate adjustment of the belt tension.
[0013] The advantages or beneficial effects of the above technical solution include at least:
[0014] The present invention discloses a belt adjustment frame of a circular knitting machine. By rotating the adjusting screw, a limit block threadably connected to the adjusting screw moves up and down along the guide rod. When the limit block is separated from the mounting seat, the limit block can be moved left and right along the groove body to adjust the position. The limit block and the mounting seat clamp the adjusting rod, thereby fixing the mounting seat and the belt pulley installed thereon, so as to facilitate the adjustment of the belt pulley position and thus adjust the tension of the belt.
[0015] At the same time, in the pulley movable part, rubber gaskets are respectively attached to the limit block and the mounting seat to increase the friction when the pulley movable part is fixed to prevent loosening during use. BRIEF DESCRIPTION OF THE DRAWINGS
