Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of circular knitting machines, and particularly relates to a saddle adjusting mechanism of a circular knitting machine. BACKGROUND

[0002] The saddle of the circular knitting machine is an important component of the circular knitting machine, and the diamond-shaped corner of the circular knitting machine is installed on the saddle, and the position of the diamond-shaped corner can be adjusted by adjusting the slide bar on the saddle.

[0003] The saddle adjusting mechanism of the circular knitting machine has the advantages that when the height position of the sliding block needs to be adjusted, the locking bolt is loosened, the sliding block is no longer in abutment with the wear-resistant block, the sliding block is pushed to slide in the sliding groove, the sliding block drives the spring to compress or elongate, the first positioning block and the second positioning block slide in the first gap and the second gap on the two sides of the sliding block, respectively, so that the position of the sliding block in the sliding groove is stably adjusted, and after the adjustment is completed, the locking bolt is used to pass through the fixed seat and abut against the wear-resistant block in the sliding groove, so that the height of the position of the wear-resistant block, i.e. the sliding block, is adjusted. However, when the saddle needs to be adjusted, the operator must first complete the unlocking operation, i.e. spend time and effort to loosen the locking bolt. After the unlocking step is completed, the adjustment of the sliding block can be carried out, and then the upward adjustment of the saddle is realized. The whole process not only needs multiple operation steps to be carried out in sequence, but also often has a certain time interval between the steps. This not only reduces the adjustment efficiency, but also makes the whole adjustment process not smooth enough, and it is difficult to meet the demand of modern production for efficient and rapid adjustment equipment.

In addition, the terms "first", "second", "third" and the like are only used for distinguishing description, and cannot be understood as indicating or implying relative importance.

[0026] As Figures 1 to 4As shown, the saddle adjusting mechanism provided in the embodiment includes a saddle body 1, a worm 2, a worm wheel 3, a rotating shaft 4, a first bearing seat 5, a fixed pulley 6, a sliding bar 7, a spring 8, a pulling rope 9, a second bearing seat 10, and a winding wheel 11. The inside of the saddle body 1 has a cavity 12 and a receiving groove 13. The first bearing seat 5 is fixed to the right side wall in the cavity 12. The right end of the worm 2 penetrates through the first bearing seat 5 and extends into the receiving groove 13. The second bearing seat 10 is fixed to the back wall in the cavity 12 below the worm 2. The back end of the rotating shaft 4 is inserted into the second bearing seat 10. The worm wheel 3 and the winding wheel 11 are both fixed to the rotating shaft 4. The worm wheel 3 is engaged with the worm 2. The fixed pulley 6 is rotatably connected to the left side wall in the cavity 12. The bottom of the saddle body 1 has a sliding groove 14. The sliding bar 7 is slidably connected in the sliding groove 14. The winding wheel 11 is wound with the pulling rope 9. One end of the pulling rope 9 penetrates through the fixed pulley 6 and is connected to the left end of the sliding bar 7. The left end of the sliding bar 7 is fixed with the spring 8. The left end of the spring 8 is fixedly connected to the left side wall in the sliding groove 14. When it is needed to adjust the position of the sliding bar 7 to the left, the worm 2 is rotated to drive the worm wheel 3 to rotate, so that the rotating shaft 4 is rotated to drive the winding wheel 11 to rotate, thereby winding the pulling rope 9. The sliding bar 7 is pulled to slide to the left through the pulling rope 9. At this time, the spring 8 is compressed. When it is needed to adjust the position of the sliding bar 7 to the right, the worm 2 is rotated in the opposite direction to drive the worm wheel 3 to rotate in the opposite direction, so that the rotating shaft 4 is rotated in the opposite direction to drive the winding wheel 11 to rotate in the opposite direction, thereby unwinding the pulling rope 9. The spring 8 is elongated. Under the action of the spring 8, the sliding bar 7 is pushed to slide to the right. In this way, the position adjustment can be realized only by simply rotating the worm 2 in the opposite direction. Through the self-locking of the worm wheel 3 and the worm 2 (the worm 2 can drive the worm wheel 3 to rotate, but the worm wheel 3 cannot drive the worm 2 to rotate), no additional locking and unlocking actions are needed. The worm 2 can be rotated when it is needed to be adjusted. The worm 2 can be stopped rotating when the adjustment is completed. The operation is convenient, and the adjustment is efficient.

[0027] The right end of the worm 2 has a hexagonal groove 15. The hexagonal wrench is inserted into the hexagonal groove 15, and then the hexagonal wrench is rotated to perform the rotating operation of the worm 2.

[0028] The scale disc 16 and the indicating groove 17 are further included. The scale disc 16 is fixedly sleeved to the right end of the worm 2. The scale disc 16 is located in the receiving groove 13. The right end of the saddle body 1 has the indicating groove 17. The indicating groove 17 is located directly above the scale disc 16. Through the arrangement of the scale disc 16 and the indicating groove 17, the adjustment condition can be more conveniently and directly understood.

[0029] The right end surface of the scale disc 16 is flush with the right end surface of the worm 2. The right end surface of the worm 2 is flush with the right end surface of the saddle body 1. In this way, the worm 2 and the scale disc 16 are avoided from being exposed to the saddle body, thereby avoiding being accidentally touched and improving the safety.

[0030] Two fixed pulleys 6 are arranged in an upper and lower distribution, the top end of the upper fixed pulley 6 is flush with the top end of the winding wheel 11, and the bottom end of the lower fixed pulley 6 is flush with the center line of the sliding bar 7. Through the arrangement of the upper and lower fixed pulleys 6, the upper and lower sections of the pull rope 9 are kept in a horizontal state, which is conducive to the smooth sending of the sliding bar 7.

[0031] The bottom of the sliding bar 7 is equally spaced along its length direction and has several mounting holes 18 for installing the rhombus. The bottom of the sliding bar 7 is equally spaced along its length direction and has several positioning holes 19, which are arranged in an interval with the mounting holes 18. The mounting holes 18 of the embodiment are threaded holes. The positioning holes 19 are first matched with the positioning column to position the rhombus, which is conducive to the alignment of the mounting position on the rhombus and the mounting hole 18, and then the installation of the rhombus is completed by inserting the bolt into the mounting hole 18. In this way, through the cooperation of the positioning hole 19 and the mounting hole 18, the accurate installation of the rhombus and the improvement of the installation stability are facilitated.

[0032] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced equivalently; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
