Embodiment
Embodiments of the present invention are illustrated by particular specific embodiment below, those skilled in the art can be by this explanation
Content disclosed by book understands other advantages and effect of the present invention easily.
It should be clear that structure, ratio, size etc. that this specification accompanying drawing is painted, only coordinating in disclosed in specification
Hold, so that those skilled in the art understands and reads, be not limited to the enforceable qualifications of the present invention, therefore do not have skill
Essential meaning in art, the modification of any structure, the change of proportionate relationship or the adjustment of size, it can be produced not influenceing the present invention
Under the effect of raw and the purpose that can reach, all should still it fall in the range of disclosed technology contents can be covered.Together
When, the term of cited such as " on ", " under " in this specification, "left", "right", " centre " and " one ", it is merely convenient to chat
State clearly, and be not used to limit the enforceable scope of the present invention, its relativeness is altered or modified, and technology is being changed without essence
Inside hold, when being also considered as the enforceable category of the present invention.
In following examples, all directions are defined as follows：The axial direction of main shaft 1 is defined as left and right directions, and the direction of main shaft 1
One end of head of sewing machine is defined as left direction, and one end of main shaft 1 towards sewing machine tail is defined as right direction；Therefore, such as Fig. 3
Shown, the left side of paper is left direction, and the right side of paper is right direction, and the upside of paper is upper direction, under the downside of paper is
Direction, the positive side of paper are rear to the dorsal part of paper is front direction.
As shown in figure 3, the application provides a kind of cloth feeding mechanism, in the lower section casing 14 of sewing machine.Such as Fig. 4 to figure
Shown in 8, the cloth feeding mechanism includes main shaft 1, feed lifting rock shaft 2, cloth pushing shaft 3, lift tooth eccentric wheel 4, work feed eccentric wheel 5, is connected to lift
Lift tooth gear unit between tooth eccentric wheel 4 and feed lifting rock shaft 2 and the work feed being connected between work feed eccentric wheel 5 and cloth pushing shaft 3
Gear unit, the main shaft 1, feed lifting rock shaft 2 are parallel with the three of cloth pushing shaft 3, all axially extending in left-right direction, and the lift tooth is eccentric
Wheel 4 and work feed eccentric wheel 5 be two separate parts, and tooth eccentric wheel 4 or the work feed eccentric wheel 5 lifted is by along main shaft 1
The screw radially extended is fixed on main shaft 1；Especially, the left end of the lift tooth eccentric wheel 4 is provided with first connecting portion 41, described to send
The right-hand member of cloth eccentric wheel 5 is provided with second connecting portion 51, and the first connecting portion 41 and second connecting portion 51 are mutually socketed；Work as work feed
When mechanism is in work feed state, first connecting portion 41 and second connecting portion 51 geo-stationary so that lift tooth eccentric wheel 4 and send
Cloth eccentric wheel 5 is with the synchronous axial system of main shaft 1.The first connecting portion 41, second connecting portion 51 and main shaft 1 are coaxially disposed, also, institute
State the right-hand member of lift tooth eccentric wheel 4 and have and be eccentric in the lift tooth connecting portion 47 of first connecting portion 41, be used for and lift tooth gear unit phase
Connection, the left end of the work feed eccentric wheel 5, which has, to be eccentric in the work feed connecting portion 55 of second connecting portion 51, is used for and work feed transmission
Unit is connected.
The sewing machine of above-mentioned cloth feeding mechanism is installed in operation process, due to first connecting portion 41 and second connecting portion 51
Geo-stationary so that it is also geo-stationary to lift tooth eccentric wheel 4 and work feed eccentric wheel 5.Therefore, motor drive shaft 1 rotates, main shaft
1 drives lift tooth eccentric wheel 4 and the synchronous axial system of work feed eccentric wheel 5, and lift tooth eccentric wheel 4 drives feed lifting rock shaft 2 by lifting tooth gear unit
Swing, feed lifting rock shaft 2 acts on retainer 9, driving retainer 9 is swung up and down；Meanwhile work feed eccentric wheel 5 is driven by work feed gear unit
Dynamic cloth pushing shaft 3 is swung, and cloth pushing shaft 3 acts on retainer 9, the driving swing of retainer 9；So that retainer 9 and being fixed on retainer 9
The feed dog 10 of upper end does work feed motion, and the movement locus of retainer 9 and feed dog 10 is up and down motion and the conjunction moved forward and backward
Into, therefore be elliptic motion trace, as shown in figure 12.Under normal circumstances, lift the lift tooth connecting portion 47 on tooth eccentric wheel 4 and send
The relative position between work feed connecting portion 55 on cloth eccentric wheel 5 is fixed, therefore work feed eccentric angle is fixed, elliptic motion trace phase
Also fixed for the position of needle plate, the work feed bias time is also fixed；When the thickness change of sewing, for example during sewing thickness material, it is
Make work feed more smooth, it is necessary to will be adjusted after the work feed bias time, now, sewing machine is stopped operating, and make described first to connect
Both socket part 41 and second connecting portion 51 relatively rotate, then lift on the lift tooth connecting portion 47 and work feed eccentric wheel 5 on tooth eccentric wheel 4
Work feed connecting portion 55 between relative position change, namely realize and adjust that work feed is eccentric and lift tooth within the specific limits
Angle between bias so that work feed eccentric angle changes, the work feed time and lift the tooth time between interval also change,
In other words, lift tooth motion and work feed motion start time difference changes, therefore the movement locus of the feed dog 10 in Figure 12 by
Elliptic motion trace K1, which becomes, turns to elliptic motion trace K2, and then will be adjusted after the work feed bias time, finally causes sewing machine
The demand of work feed bias time is adjusted after disclosure satisfy that during thick material sewing, improves the thick material adaptability of sewing machine.In addition, when the first company
When socket part 41 and both relative rotations of second connecting portion 51, lift tooth eccentric throw, work feed between lift tooth connecting portion 47 and main shaft 1 connect
Work feed eccentric throw between socket part 55 and main shaft 1 does not change, therefore needle gage size is constant；In other words, the application realizes
On the premise of not changing needle gage size, the step-less adjustment of work feed bias time can be realized within the specific limits.
It is following exemplified by lifting tooth eccentric wheel 4 and be fixed on main shaft 1, to lift tooth eccentric wheel 4 and the attachment structure of work feed eccentric wheel 5
