Definitions

the present invention relates to a sinker of knitting machines and particularly to a sinker equipped with lubrication oil channeling and separating structure.
a conventional sinker 10 on a knitting machine generally can be moved reciprocally to-and- fro by driving a nub 11 formed thereon.
the sinker 10 is in operation reciprocally for a prolonged period of time, other portions of the sinker 11 such as the push friction end 101, first driving friction end 111, second driving friction end 112 and loading friction end 121 have to be properly cooled and lubricated.
the most common approach at present is applying lubrication oil.
the sinker 10 includes an oil sprinkling zone 14 to receive lubrication oil 71 sprinkled from an oil ejection nozzle 70, and the lubrication oil 71 flows downward after sprinkling to cool and lubricate the push friction end 101, first driving friction end 111, second driving friction end 112 and loading friction end 121.
the design and structure of the conventional sinker 10 often do not take into account of the lubrication oil could flow to the knitting portion 13, yarns in the knitting portion 13 could be smeared by the lubrication oil during knitting operation and result in increasing of quality defects of the knitting fabrics.
Taiwan patent No. M365935 discloses an improvement for a sinker that mainly includes a flank, a nose at an upper side of the rear end of the flank, a nose located at a upper side of a rear end of the flank, a guide portion at a lower side of the rear end, and a notch at the bottom edge of the flank that can be formed in a square, a trapezoid, an arc or other shapes.
the notch also shapes the bottom edge of the flank to form a front bottom edge and a rear bottom edge.
the guide portion and the flank are spaced from each other.
the guide portion is jutting at a length to cover the notch, namely the jutting portion of the guide portion includes a front end formed at a size slightly greater than or equal to the location distance of the front end wall of the notch.
the guide portion is located below the rear end of the flank.
the sinker also includes a guiding nub at the read side. Through the aforesaid structure when the sinker and its corresponding knitting needle are in knitting operation they can be positioned at the notch to fend off lubrication oil.
the primary object of the present invention is to solve the shortcomings and problems of the conventional technique by providing a solution that can fully and effectively separate lubrication oil from in contact with yarns or knitting fabrics thereof to improve fabric quality to meet industry and market requirements.
the present invention provides a sinker equipped with lubrication oil channeling and separating structure.
the sinker is a knitting element used on a knitting machine.
the knitting machine includes at least a dial, a sinker disc, an oil ejection nozzle located above the sinker disc and a yarn feeder located above the dial and the sinker disc.
the dial includes a plurality of needle troughs to hold respectively a knitting needle.
the sinker disc includes a plurality of sinker troughs corresponding to the needle troughs to hold the sinker.
the sinker includes a base slidable in the sinker troughs and generating friction therewith, a driving nub located above the base, a knitting portion located at a front end of the base, an oil sprinkling zone interposed between the base and the knitting portion corresponding to the oil ejection nozzle, and a lubrication oil channeling and separating structure interposed between the knitting portion and the oil sprinkling zone.
the lubrication oil channeling and separating structure includes a separating slot formed upward from a lower side, a flow channeling portion around the separating slot and close to the oil sprinkling zone, and an oil blocking portion around the separating slot and close to the knitting portion.
the lubrication oil channeling and separating structure further includes a jutting debris push portion around the separating slot and below the flow channeling portion.
the flow channeling portion is inclined from a top end thereof downward towards the oil blocking portion.
the oil blocking portion is interposed between the separating slot and the knitting portion, and when the sinker has fully finished withdrawing or push out movement the oil blocking portion is located outside the sinker trough.
the invention through the construction set forth above, compared with the conventional techniques, can provide many advantages, such as: the flow channeling portion, the debris push portion and the oil blocking portion are formed around the separating slot that provide respectively different functions of flow channeling, debris pushing and oil blocking, hence the flow channeling portion and the oil blocking portion not only can fully separate lubrication oil from in contact with yarns or the knitting fabrics thereof, the debris push portion can also push out cotton debris sunk into the sinker troughs during knitting operation to improve sliding smoothness of the sinker in the sinker troughs, thereby can improve the quality of the knitting fabrics to meet industry and market requirements.
the present invention aims to provide a sinker equipped with lubrication oil channeling and separating structure.
the sinker 30 is a knitting element used in a knitting machine 20.
the knitting machine 20 includes at least a dial 40, a sinker disc 60, an oil ejection nozzle 70 located above the sinker disc 60 to sprinkle lubrication oil 71 and a yarn feeder 80 located above the dial 40 and the sinker disc 60.
the dial includes a plurality of needle troughs 41 to hold respectively a knitting needle 50.
the sinker disc 60 has a plurality of sinker troughs 61 corresponding to the needle troughs 41 to hold the sinker 30.
the sinker 30 includes a base 32 slidable in the sinker troughs 61 to generate friction therewith, a driving nub 31 located above the base 32, a knitting portion 33 located at a front end of the base 32, and an oil sprinkling zone 34 interposed between the base 32 and the knitting portion 33 corresponding to the oil ejection nozzle 70. While the sinker 30 is driven mainly four frictional portions are generated, including a push-out friction end 310, a first driving friction end 311, a second driving friction end 312 and a loading friction end 321.
the oil ejection nozzle 70 is directly located above the oil sprinkling zone 34 so that the lubrication oil 71 can enhance lubrication and cooling through the oil sprinkling zone 34 to the push-out friction end 310 , the first driving friction end 311, the second driving friction end 312 and the loading friction end 321. It is to be noted that the invention also includes a lubrication oil channeling and separating structure 300 interposed between the knitting portion 33 and the oil sprinkling zone 34.
the lubrication oil channeling and separating structure 300 includes a separating slot 301 formed upward from a lower side, a flow channeling portion 302 around the separating slot 301 and close to the oil sprinkling zone 34, and an oil blocking portion 304 around the separating slot 301 and close to the knitting portion 33. It is also to be noted that the lubrication oil channeling and separating structure 300 further includes a jutting debris push portion 303 located around the separating slot 301 below the flow channeling portion 302.
the debris push portion 303 When the sinker 30 has fully finished withdrawing movement on the sinker disc 60 the debris push portion 303 is fully withdrawn inside the sinker trough 61, and when the sinker 30 has been fully pushed out from the sinker disc 60 the debris push portion 303 is exposed outside the sinker trough 61. Moreover, the flow channeling portion 302 is inclined from a top end downward towards the oil blocking portion 304. The oil blocking portion 304 is interposed between the separating slot 301 and the knitting portion 33, and when the sinker 30 has fully finished withdrawing or push out movement the oil blocking portion 304 is located outside the sinker trough 61.
the sinker 30 when the invention is in use, the sinker 30 can be driven and swiveled, and the driving nub 31 is driven to allow the sinker 30 to be fully pushed out from the sinker disc 60 beneath the oil ejection nozzle 70, while the oil ejection nozzle 70 continuously sprinkles the lubrication oil 71 the oil sprinkling zone 34 receive sprinkling of the lubrication oil 71 which starts to flow downward to the base 32 as shown in FIG. 4 .
the sinker 30 When the sinker 30 is driven continuously and swivels to start withdrawing movement it also moves away from where the oil ejection nozzle 70 sprinkles the lubrication oil 71, hence although the oil ejection nozzle 70 continuously sprinkles the lubrication oil 71 the oil sprinkling zone 34 of the sinker 30 does not receive sprinkling of the lubrication oil 71, while the lubrication oil 71 received previously flows naturally toward the base 32 and enters the sinker trough 61 as shown in FIG. 6 .
a sinker being equipped with lubrication oil channeling and separating structure and being formed to serve a knitting element of a knitting machine which includes at least a dial 40, a sinker disc 60, an oil ejection nozzle 70 to sprinkle lubrication oil 71 and a yarn feeder 80.
the dial 40 includes a plurality of needle troughs 41 to hold respectively a knitting needle 50.
the sinker disc 60 includes a plurality of sinker troughs 61 corresponding to the needle troughs 41 to hold the sinker 30.
the sinker 30 includes a base 32 located in the sinker troughs 61, a driving nub 31 located above the base 32, a knitting portion 33 located at a front end of the base 32, an oil sprinkling zone 34 interposed between the base 32 and the knitting portion 33 corresponding to the oil ejection nozzle 70, and a lubrication oil channeling and separating structure 300 interposed between the knitting portion 33 and the oil sprinkling zone 34.
the lubrication oil channeling and separating structure 300 includes a separating slot 301, a flow channeling portion 302 and an oil blocking portion 304 that are around the separating slot 301, thus can fully achieve separation effect to improve quality of knitting fabrics to meet industry and market requirements.
the sinker of the invention includes the lubrication oil channeling and separating structure which includes the flow channeling portion, the debris push portion and the oil blocking portion formed around the separating slot, and the flow channeling portion, the debris push portion and the oil blocking portion can provide various functions such as accelerating flow directing and downward of the lubrication oil, push out of the debris dropped into the sinker trough, and also block the lubrication oil from flowing to the knitting portion.
the flow channeling portion and the oil blocking portion not only can fully separate the lubrication oil from in contact with the yarns or their fabrics, the debris push portion also can push the debris dropped into the sinker trough during knitting operation to improve sliding smoothness of the sinker in the sinker trough, thereby enhance fabric quality to better meet industry and market requirements.
