Description

Technical Field

[0001] The utility model belongs to the technical field of knitting machines, and particularly relates to a presser cam for a knitting machine. Background Technique

[0002] The presser cam is one of the core components of a knitting machine and a key component of the cam system. It is mainly used to control the lifting movement of the knitting needles to ensure the stability of the loop-forming process. Its working principle is to guide the knitting needles to move along a preset trajectory through an inclined plane structure, press the needle hooks during the descending stage, assist in the doffing of the old loops and form new loops;

[0003] After retrieval, a presser cam for a double-sided rib knitting machine disclosed in the publication number CN210237962U includes a cam base. When the above device is in use, although the operation is convenient and simple, it is difficult to detect the displacement of the presser cam during equipment inspection, which is likely to affect the product quality. Therefore, a presser cam for a knitting machine is proposed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a presser cam for a knitting machine, which can magnify the moving distance of a sliding rod through a lever, and then can facilitate the staff to timely detect whether the sliding plate moves during equipment inspection, is convenient to use, and can effectively prevent the screw rod from rotating itself, improving the stability of the sliding plate after adjustment, and solving the existing technical problems.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] A presser cam for a knitting machine, comprising: a cam base and a presser cam arranged on one side of the cam base. Two sliding grooves are opened on one side of the cam base, and sliding rods are slidably connected in both of the two sliding grooves. A sliding plate is fixedly connected between the two sliding rods, and the presser cam is fixed on one side of the sliding plate through bolts;

[0007] A warning mechanism, which is arranged on one side of one of the sliding rods to display the displacement of the presser cam. The warning mechanism includes a lever and an arc-shaped indicator board. The lever is rotatably connected to one side of the cam base. One end of the lever abuts against the top of one of the sliding rods. An elastic member for keeping the lever in contact with the sliding rod is arranged between the lever and the cam base. The arc-shaped indicator board is fixed on one side of the cam base and is used in cooperation with the lever. The rotation point of the lever is close to the sliding rod. Through the cooperation between the lever and the arc-shaped indicator board, the moving distance of the sliding rod can be magnified by the lever, and then it can facilitate the staff to timely detect whether the sliding plate moves during equipment inspection, which is convenient to use;

[0008] An adjusting component, which is arranged between the cam base and the sliding plate to adjust the height of the presser cam.

[0009] As a further solution of the present utility model, one end of the lever close to the arc-shaped indicator board is provided with an inclined surface, and the inclined surface is located on one side of the arc-shaped indicator board.

[0010] As a further solution of the present utility model, the elastic member is a tension spring, and the tension spring is fixed between the triangular seat and the lever.

[0011] As a further solution of the present utility model, the adjusting assembly includes a worm, an avoidance groove and a worm gear. The avoidance groove is opened on one side of the triangular seat close to the sliding plate. Two fixing blocks are slidably connected in the avoidance groove, and both fixing blocks are fixed to the sliding plate. A threaded rod is threaded through between the two fixing blocks and rotatably penetrates through the top of the triangular seat. The worm gear is fixed to the top of the threaded rod. The worm is rotatably connected to the top of the triangular seat and meshes with the worm gear. By using the setting of driving the worm gear to drive the threaded rod to rotate by the worm, the self-locking characteristic of the worm gear and worm can effectively prevent the threaded rod from rotating by itself and improve the stability of the sliding plate after adjustment.

[0012] As a further solution of the present utility model, the adjusting assembly includes a cylinder fixed on one side of the triangular seat, and one end of the piston rod of the cylinder is fixed to the side of the sliding plate away from the press needle triangle.

[0013] As a further solution of the present utility model, a protective shell is fixedly connected to the top of the triangular seat, and the worm rotatably penetrates through the protective shell.

[0014] As a further solution of the present utility model, a scale disk is fixedly connected to one side of the protective shell, and a pointer matched with the scale disk is fixedly connected to the circumference of the worm.

[0015] As a further solution of the present utility model, a handwheel is fixedly connected to one end of the worm.

[0016] In this application, when adjusting the height of the press needle triangle, the worm is rotated by the handwheel. The worm drives the threaded rod to rotate through the worm gear. The threaded rod drives the fixing blocks and the sliding plate to move, thereby adjusting the height of the press needle triangle. At the same time, through the cooperation of the worm gear and the worm, it can effectively prevent the displacement of the sliding plate caused by the self-rotation of the threaded rod and improve the stability of the sliding plate after adjustment. During the movement of the sliding plate, the sliding rod moves synchronously, and then changes the angle of the lever by contacting the lever, and records the position where the lever points to the arc-shaped indicator board. When checking the equipment, it can be found that the position of the lever has changed, avoiding the problem that it is difficult to find after the position of the press needle triangle has changed, which is convenient to use.

[0017] The embodiments of the present utility model have the following beneficial effects:

[0018] In the present utility model, through the combined use between the lever and the arc-shaped indicator board, the moving distance of the slide bar can be amplified by the lever, so that it is convenient for the staff to timely discover whether the slide plate moves during the inspection of the equipment, which is convenient to use;

[0019] In the present utility model, through the setting of using the worm to drive the worm wheel to drive the threaded rod to rotate, the self-locking characteristic of the worm and worm wheel can effectively prevent the threaded rod from rotating by itself, and improve the stability of the slide plate after adjustment;

[0020] In the present utility model, the moving distance of the slide bar can be amplified by the lever, so that it is convenient for the staff to timely discover whether the slide plate moves during the inspection of the equipment, which is convenient to use. At the same time, it can effectively prevent the threaded rod from rotating by itself and improve the stability of the slide plate after adjustment.
