Description
Technical field
The invention belongs to field of mechanical technique, relate to a kind of Sewing machines, particularly a kind of roller car is just stitching and is backstitching switching-driving device.
Background technology
At present, it is that body is provided with switching device shifter mostly that the roller car backstitches driving mechanism, when the Sewing machines desire is implemented to backstitch, can be by the power transmitting elements that starts in the column that the switching device shifter ejection defaults in Sewing machines, interlock lower link and upper connecting rod action, and drive the arrangement of clutch that it presses element pressure holding and last power transmission shaft and lower drive shaft assembly respectively, make and be the state that clip links or discharge idle running between this arrangement of clutch and power transmission shaft, select power transmission shaft and lower drive shaft to the shaft-driven pattern of this transmission respectively, and in the drive or down drawing-inroller is just producing, reverse, the work object of providing is just stitching feeding or is backstitching feeding.Its weak point is: the clutch configuration complexity of the Backsewing unit of above-mentioned industrial sewing machine make trouble and the manufacturing cost height, and stuck phenomenon appears in mechanism easily.
Its publication number of Chinese patent CN1313419A provides a kind of " Backsewing unit of industrial sewing machine ", start the switching device shifter ejection when it need backstitch and be preset in the interior power transmitting elements of Sewing machines column, connecting rod lower link and upper connecting rod action, and control arrangement of clutch, last or the following feed spool of final drive is to the shaft-driven pattern of this transmission, and in the drive or down drawing-inroller is just producing, is reversing, and just the sewing feeding or backstitch feeding of workpiece object is provided.
But, have too much part in the above-mentioned patent, exist baroque problem equally.
Summary of the invention
The objective of the invention is the problems referred to above of existing at prior art, provide a kind of and switch just stitching feeding and backstitch between the feeding flexibly, and make roller car easy to assembly and just stitching and backstitch switching-driving device.
Purpose of the present invention can realize by following technical proposal: a kind of roller car is just stitching and is backstitching switching-driving device, comprise the power transmission shaft that links to each other with feed mechanism, it is characterized in that, this switching-driving device comprises and is connected in the switching shaft that can rotate in the roller car casing, described switching shaft links to each other with an actuator that can drive its translation, have two driving members one on the described switching shaft, have the driving member two between two driving members one on the described power transmission shaft, and driving member two can link with above-mentioned any one driving member one.
Just stitching at this roller car and to backstitch in the switching-driving device, after actuator moves to right switching shaft, driving member one and driving member two engagements that switching shaft keeps left, the switching shaft of rotation drives power transmission shaft just to be changeed, and by power transmission shaft action is passed to feed mechanism again;
After actuator drive switching shaft moved to left, driving member one and driving member two engagements that switching shaft is kept right were rotated switching shaft and are driven the power transmission shaft counter-rotating, by power transmission shaft action are passed to feed mechanism again.Certainly, because power transmission shaft switched in opposite during above-mentioned two states makes the roller car be in respectively and is just stitching and backstitching state.
Just stitching at above-mentioned roller car and to backstitch in the switching-driving device, described switching device shifter actuator is electromagnet, and the iron core of electromagnet and switching shaft link and can drive the switching shaft translation.
Make switching shaft to move stably by stretching out with retraction of iron core.
Just stitching at above-mentioned roller car and to backstitch in the switching-driving device, also be hinged with connecting rod on the casing of described roller car, an end of connecting rod and the iron core of electromagnet are hinged, and the other end of connecting rod is movably connected on the switching shaft.
Make above-mentioned switching shaft translation by connecting rod as driving member in the iron core telescopic process.
Just stitching at above-mentioned roller car and to backstitch in the switching-driving device, described switching shaft end is fixed with bearing, and above-mentioned connecting rod has the draw-in groove that can be connected to bearing outer ring.
The structure of bearing and draw-in groove makes connecting rod can drive switching shaft and moves that simultaneously, what switching shaft can also be stable rotates with respect to connecting rod.
Just stitching at above-mentioned roller car and to backstitch in the switching-driving device, be provided with spring between described connecting rod or switching shaft and the roller car casing, the driving member two on switching shaft under the elastic force effect of spring has the trend that links with one of them driving member one.
The trend that makes switching shaft have under the elastic force effect of spring to move to right makes the driving member one that is positioned at the switching shaft left side link with driving member two like this, rotates thereby the driving member one by the left side drives power transmission shaft.
Just stitching at above-mentioned roller car and to backstitch in the switching-driving device, described driving member one and driving member two are bevel gear.
Obviously, bevel gear on the power transmission shaft can with switching shaft on the engagement of any one bevel gear, because two bevel gear rotation directions on the switching shaft all are consistent, bevel gears different on the bevel gear on the power transmission shaft and the switching shaft mesh the forward or reverse that just can realize power transmission shaft.
Just stitching at above-mentioned roller car and to backstitch in the switching-driving device, described driving member one and driving member two are friction pulley.
The friction pulley that employing has a tapering can be realized the purpose of the positive and negative rotation of feeding equally.
Just stitching at above-mentioned roller car and to backstitch in the switching-driving device, described driving member one is connected on the switching shaft by securing member.
Just stitching at above-mentioned roller car and to backstitch in the switching-driving device, described driving member two is connected on the power transmission shaft by securing member.
Securing member is screw, adopts to make driving member one firm being connected on the switching shaft in such a way, or makes driving member two firm being connected on the power transmission shaft.
Compared with prior art, this roller car is just stitching and is backstitching switching-driving device and only be made up of switching shaft, connecting rod and electromagnet etc., and therefore, it is simple in structure, low cost of manufacture.
Simultaneously, adopt bearing to make switching shaft to rotate with respect to connecting rod smoothly between switching shaft and the connecting rod, therefore, its can flexible conversion forward feeding and reverse feeding and is not easy to occur stuck phenomenon.
