Cam driving structure of linking machine

Abstract

The invention relates to sweater knitting machinery equipment, in particular to a cam driving structure of a linking machine. The cam driving structure comprises a spindle, a support, a first driving cam, a first transmission rocker rod, a second driving cam, a second transmission rocker rod, a third driving cam and a compensation mechanism. One end of the spindle is connected with a table, the first driving cam, the second driving cam and the third driving cam are fixed on the spindle, the second transmission rocker rod is connected with a second pin shaft, and one end of the second pin shaft is fixed on the table. One end of the support is connected with the table while the other end of the same is connected with the spindle, and the first transmission rocker rod is fixed on the support through a first pin shaft. The compensation mechanism comprises a compensation driving cam, a compensation transmission rocker rod and a compensation tension spring, the compensation driving cam is fixed on the spindle, and the compensation transmission rocker rod is fixed on the support through screws for bearings. The first transmission rocker rod is enabled to be in cyclic motion along the peripheral curved surface of the first driving cam under matched joint action of the compensation mechanism and the first driving cam as well as the first transmission rocker rod, and stable running and low resistance are realized. A loose running state of a previous transmission rocker rod roller bearing in a big wheel side face groove is changed, so that the linking machine can run quickly and is lower in fault rate and more convenient to maintain and debug.

Description

technical field [0001] The invention relates to a sweater knitting machine, in particular to a cam driving structure of a disc sewing machine. Background technique [0002] The sewing machine is an important equipment for sweater sewing. At present, there are two main types of disc sewing machines on the market: one is the ordinary connecting rod disc sewing machine, which has the advantages of simple structure and wide application range, but the disadvantage is that the large driving wheel adopts a loose driving method, resulting in unstable performance and slow speed; The other is a high-speed sewing machine, which has the advantages of stable performance and fast speed, but the disadvantage is that the passing hole is too small, and it is difficult for the shirt to pass through when sewing pockets or other accessories in the middle of a large piece, which limits the scope of use. Because most of its parts are concentrated in the oil-proof cover of the machine head, it is...
