Description
The utility model relates to Sewing machines.
Existing industrial sewing machines, as shown in Figure 1, 2: it backstitches the rotation aspect of two drawing-inrollers up and down of its working substance travel direction of relevant controlling in the operation, and the suture needle whereabouts and the lifting time of cooperating thing moving direction, controlled by three tool electromagnetic valve A, B, C respectively, three electromagnetic valve A, B, C are parallel to same release knob; Be provided with clutch gear group D between the wheel shaft of last drawing-inroller and axle bed, be subjected to electromagnetic valve A effect and separate drawing-inroller is dallied; The following drawing-inroller wheel shaft other end is provided with travelling gear, this travelling gear and the unification of two relative positive and negative two umbrella shapes wheels of coaxial rotation, clutch gear group E be subjected to electromagnetic valve C to do that the time spent travelling gear separates with positive bevel gear and with anti-bevel gear interlock, drawing-inroller is reversed;
Though it may be used, have following disappearance:
(1) needs to act on simultaneously, begin to such an extent that startup backstitches system, except that the electromagnetic valve manufacturing cost is higher by three electromagnetic valve A, B, C, the work that continues of its circuit is also complicated, and in addition, this electromagnetic valve belongs to electronic product, tool certain service life, it is easy to generate fault in inhaling, put action for a long time repeatedly, again in this mechanism, if any arbitrary solenoid valve failure, then can't implement to backstitch, when use on the historical facts or anecdotes border, often need guarantee regularly to safeguard that its fault rate is also higher.
(2) after this electromagnetic valve A, C start, drive clutch gear group D, E respectively and produce disengaging or engagement, so that producing, the work object advances or the direction of retreat variation, because tool certain distance between clutch gear group D, each tooth row of E, and the Sewing machines running speed is fast, and engagement rapidly in a short period of time makes between its gear train tooth row and can begin to such an extent that engage after the generation severe impact, so in use for some time, often there is the tooth row breakdown to cause that engagement is bad maybe can't mesh.
(3) as described in the preceding paragraph, engagement rapidly in a short period of time between this tooth row because its strength of impacting engaging is big, can often produce acute big vibrations and noise, and the operating personnel is manipulated down for a long time, can produce discomfort, even employment injuries.
The purpose of this utility model provides a kind of transmission engagement better, and fault is few, wearing and tearing and the less industrial sewing machine Backsewing unit of noise.
The purpose of this utility model is achieved in that the industrial sewing machine Backsewing unit, the body of this Sewing machines is provided with a switching device shifter, and the power transmitting elements in the Sewing machines column in ejection, and interlock lower link and upper connecting rod drive it again respectively and press the arrangement of clutch top that element and pressure arm pressure holding and following feed spool and last feed spool group are put; It is characterized in that: should comprise with the arrangement of clutch that the lower link group is put: power transmission shaft, first driver element and second driver element, power transmission shaft is positioned the body bottom surface, and cover is organized first and second driver element in regular turn, and its top protrudes out and exceeds arrangement of clutch, and it is subjected to lower link to press the binding first or second driver element of passing and selecting to switch; This first and second driver element is connected with first, second connection rod set respectively and is connected with following feed spool, and between first, second connection rod set, have 180 the degree passing differ; Power transmission shaft is installed with and drives the bevel gear that drawing-inroller is just producing, reversing under the travelling gear interlock; This upper connecting rod group is equipped with another arrangement of clutch, this arrangement of clutch is made up of power transmission shaft and driver element, this power transmission shaft is positioned head of sewing machine portion, and cover is organized in driver element, its top is to protrude out to exceed arrangement of clutch, and pressed down by upper connecting rod start interlock pressure arm to pass and make itself and driver element break away from clip.
Above-mentioned design is used according to test, has reached and has meshed, and fault is few, the good result that noise is little.
