Abstract
The invention relates to the technical field of mechanisms of sewing machines, in particular to a continuous cloth feeding mechanism for a sewing machine. The problems that a soft smooth fabric is easily misplaced and wrinkled and misplacement is severer when the fabric is longer in the prior art are solved. The mechanism comprises a cloth feeding shaft, a lower shaft, a cloth feeding crank, a first tooth lifting connecting rod, a tooth lifting cam, a first tooth frame and a first cloth feeding tooth, and is characterized in that: the tooth lifting cam has a structure that double cams are symmetrically arranged in a straight line; the first tooth lifting connecting rod and a second tooth lifting connecting rod are arranged on the tooth lifting cam; the cloth feeding crank comprises double vertical driving ends which are symmetrically arranged in a straight line; the first tool frame is arranged between one driving end of the cloth feeding crank and the action end of the first tooth lifting connecting rod; a second tool frame is arranged between the other driving end of the cloth feeding crank and the action end of the second tooth lifting connecting rod; and a second cloth feeding tooth is arranged on the second tool frame and parallel to the first cloth feeding cloth.
Description
Technical field:
The present invention relates to Sewing machines mechanism technical field, be specifically related to the continuous cloth feeding mechanism of a kind of use in sewing machine.
Background technology:
Cloth feeding mechanism under being that adopt on traditional single needle lockstitch m/c has also that to have adopted the Needle cloth-feeding mechanism that can prevent the sewing creep on the single needle lockstitch m/c be the Needle cloth-feeding flat seam machine more.The essential structure of following cloth feeding mechanism and Needle cloth-feeding mechanism includes cloth pushing shaft, lower shaft, cloth feeding crank, lifts tooth connecting rod, tooth lifting cam, retainer and feed dog, and retainer is arranged at cloth feeding crank and lifts between the motion end of tooth connecting rod.
The operation principle of following cloth feeding mechanism is: eedle is done and is pumped; Feed dog is done the sub-elliptical motion; Feed dog is at needle plate moved beneath (not work feed) when eedle entering needle plate thorn passes through cloth; When eedle was above needle plate, feed dog (presser feet is pushed down feed dog) beginning work feed action that moves upward realized intermittently work feed; The operation principle of Needle cloth-feeding mechanism is: eedle is done the swing simultaneously that pumps; Feed dog (band pin hole) is done the sub-elliptical motion; Feed dog (presser feet is pushed down feed dog) above needle plate when eedle gets into the needle plate thorn and passes through cloth, eedle are pricked into the feed dog pin hole with the feed dog work feed, when eedle moves to the needle plate top; Feed dog moves downward the action of beginning work feed, realizes intermittently work feed.The problem that the former exists is: the slippage lining is prone to produce dislocation relatively, and lining is long more, and it is many more to misplace; Though the problem that the latter exists is to alleviate relative slippage lining dislocation, feed dog rises and falls greatly in the process but make, and is also wrinkling easily for the soft smooth lining.
Summary of the invention:
The present invention wants the continuous cloth feeding mechanism of a kind of use in sewing machine, is prone to produce dislocation to overcome soft smooth lining that prior art exists, wrinkling problem and lining is long more, and more problems misplace.
For overcoming the problem that prior art exists; The present invention provides a kind of use in sewing machine continuous cloth feeding mechanism; Comprise that cloth pushing shaft, lower shaft, cloth feeding crank, first lift tooth connecting rod, tooth lifting cam, first retainer and first feed dog; It is characterized in that: described tooth lifting cam is to be 180 ° of symmetrically arranged double cam structures, and tooth lifting cam is provided with first and lifts tooth connecting rod and second and lift the tooth connecting rod; Comprise the vertical 180 ° of symmetrically arranged double end drive ends that are on the said cloth feeding crank; First retainer is arranged at drive end and first of cloth feeding crank and lifts between the motion end of tooth connecting rod; Second retainer is arranged at another drive end and second of cloth feeding crank and lifts between the motion end of tooth connecting rod, and second feed dog is arranged on second retainer and with first feed dog and laterally arranges.
Continuous cloth feeding mechanism provided by the present invention is the compound motion of following cloth feeding mechanism and Needle cloth-feeding mechanism, and compared with prior art, advantage of the present invention is:
1, no matter pin upper still pin is the next, feed dog alternately is positioned at the needle plate top, can guarantee mild work feed, improves the work feed quality.
2, feeding is more level and smooth, and thread tension can reduce by 30%, adaptable across various sewings, is more suitable for making of thin material, can realize high-quality sewing.
3, it goes without doing changes for other part of Sewing machines, only needs to enlarge the opening on the needle plate, first feed dog and second feed dog can be arranged in it get final product.
Description of drawings:
Fig. 1 is the structure diagram of following cloth feeding mechanism;
Fig. 2 is the structure diagram of Needle cloth-feeding mechanism;
Fig. 3 is a structure diagram of the present invention;
Fig. 4 is a utilization structure sketch map of the present invention.
1-cloth pushing shaft, 2-lower shaft, 3-cloth feeding crank, 4-lift tooth connecting rod, 5-tooth lifting cam, 6-retainer, 7-feed dog, 8-second and lift tooth connecting rod, 9-second retainer, 10-second feed dog, 11-needle plate, 12-presser feet.
The specific embodiment:
To combine accompanying drawing that the present invention is at length explained below.
Referring to Fig. 1 and Fig. 2; The essential structure of following cloth feeding mechanism and Needle cloth-feeding mechanism includes cloth pushing shaft 1, lower shaft 2, cloth feeding crank 3, lifts tooth connecting rod 4, tooth lifting cam 5, retainer 6 and feed dog 7; Described lower shaft 2 is provided with the cam action assembly of lifting tooth connecting rod 4 and tooth lifting cam 5 formations, and retainer 6 is arranged at cloth feeding crank 3 and lifts between the motion end of tooth connecting rod 4.
Referring to Fig. 3, the continuous cloth feeding mechanism of a kind of use in sewing machine comprises that cloth pushing shaft 1, lower shaft 2, cloth feeding crank 3, first are lifted tooth connecting rod 4, tooth lifting cam 5, first retainer 6, first feed dog 7, second is lifted tooth connecting rod 8, second retainer 9 and second feed dog 10.Described tooth lifting cam 5 is to be 180 ° of symmetrically arranged double cam structures (comprise on the tooth lifting cam 5 and be 180 ° of symmetrically arranged off-centre), and tooth lifting cam 5 is provided with first and lifts tooth connecting rod 4 and second and lift tooth connecting rod 8; Comprise the vertical 180 ° of symmetrically arranged double end drive ends that are on the said cloth feeding crank 3; First retainer 6 is arranged at drive end and first of cloth feeding crank 3 and lifts between the motion end of tooth connecting rod 4; Second retainer 9 is arranged at another drive end and second of cloth feeding crank 3 and lifts between the motion end of tooth connecting rod 8, and second feed dog 10 is arranged on second retainer 9 and with first feed dog 7 and laterally arranges.
Referring to Fig. 4, first feed dog 7 and second feed dog 10 are arranged in the opening of needle plate 11, presser feet 12 be arranged at first feed dog 7 and second feed dog 10 directly over.
The course of work of the present invention is:
Eedle is done the swing simultaneously that pumps; Two feed dogs are done the sub-elliptical motion, are with pin hole feed dog 7 upwards to push down the sewing work feed with presser feet 12 when eedle gets into when the needle plate thorn passes through cloth, when eedle moves to the needle plate top; Outer feed dog 10 moves upward and begins to push down the sewing work feed with presser feet 12; Realize continuous work feed, because work feed does not have fluctuating continuously, sewing quality improves greatly.
