Description of the Invention: [Technical Field] The present invention relates to a structural improvement of a knitting machine Sinker, in particular to an improvement of the partial thickness of a raw sheet of a knitting machine, which reduces friction and increases lubrication. The function, in turn, can increase the speed of the machine and reduce the effect of wear and increase the service life. [Prior Art] According to the knitting needle of the knitting machine, the process of regular lifting, the rewinding of the yarn, the ferrule, the loop, the unwinding, the looping, etc. are all made by the knitting machine. (Sinker) control, only when the raw gram film is kept in a stable and regular movement process, can realize the functions of the wire unwinding and rewinding. As shown in the first figure, the slab is in a planar geometry, and since only the front end is provided with a concave surface, the concave end is not formed at the trailing end. However, such a structure easily leads to a very tight space between the slab (10') and the annular groove, and as the number of needle slots per inch increases, the slab (10,) and the annular groove Q The space between them will become closer and closer, which will easily cause the end of the gram (1 〇,) to rub against the ring groove and reduce its service life (this type of patent can be found in Announcement No. 258216). Therefore, the present inventors have been able to improve the above-mentioned defects in order to reduce the friction and increase the service life. SUMMARY OF THE INVENTION The main object of the present invention is to provide a Sinker structure improvement of a knitting machine, which has a longitudinal direction of a thickness of the sheet 2010 437 437 437 437 437 437 437 437 437 437 437 437 437 437 437 437 437 437 437 437 437 437 437 437 437 437 The area of friction between the ring grooves promotes smoother machine movements and increases the usefulness of the service life. In order to achieve the above object, the technical means adopted by the present invention comprises: the base system is geometrically planar, and is composed of a combination of a nose, a throat, a tablet and a sheet clock; wherein the nose, the throat, and the tablet The lanthanoid system is disposed at the front end of the sheet, and the sides of the sheet nose, the throat, and the sheet are recessed in the thickness direction to form a concave groove having a middle low and a symmetrical recess on both sides; the feature is: the back end of the base In the vicinity of the sheet, at least one of the sides is provided with a longitudinal concave surface such that the thickness (t2) at the longitudinal concave surface is smaller than the thickness (tO) of the crucible. Thus, the present invention utilizes a modified Sinker portion. The thickness is used to reduce the friction and increase the lubrication function, and at the same time, because the function of the lubricating oil (〇) in the weaving operation is fully exerted, the life of the slab and the annular groove which itself is the wearing part is longer. First of all, 'see the second figure' is a perspective view of the invention, the base system is geometrically planar, and consists of a nose (11), a throat (12), a sheet (13) and a sheet (14). ) combined; The piece of nose (11), the throat (12), and the piece (13) are disposed at the front end of the seed (14); the piece of nose (11), the throat (12), and the piece (13) The two sides of the thickness direction are recessed to form a recess (15) having a centrally low, two-sided high-symmetric recess; wherein the base has a rear end adjacent to the sheet bundle (14), and at least one of the sides is provided with a longitudinal concave surface (16). The thickness of the longitudinal concave surface (16) is smaller than the thickness (t!) of the sheet bundle (14). 201043742 In addition, the longitudinal concave surface (16) is provided on the left and right sides and is symmetrical. The shape is not limited thereto, and may be included on one side of the base body. Further, referring to the third to fifth figures, the present invention utilizes the improvement of the thickness (t2) of the longitudinal concave surface (16) to be smaller than The thickness of the sheet (14) (tO structure, according to the formation of the longitudinal concave surface (16) can increase the gap space between the raw sheet (10) and the annular groove (21), thereby allowing the space to be included More lubricant (0), which increases lubrication and reduces friction to achieve either a smear (10) or a ring groove (2) 1) It can be used to extend the usefulness of the service life. Therefore, the technical features of the present invention have the advantages of improving performance and productivity, and reducing the loss rate of consumables, which is in fact economical and cost-effective. The technical means disclosed are indeed the invention patents such as "novelty", "progressiveness" and "available for industrial use", and pray that the bureau will grant a patent to encourage invention and no sense of morality. The drawings and descriptions of the present invention are merely preferred embodiments of the present invention, and modifications or equivalent changes made by those skilled in the art according to the spirit of the present invention should still be included in the scope of the patent application of the present application. ❹ -5- 201043742 [Simple description of the drawings] The first picture is a perspective view of a conventional knitting machine.
