Abstract
The utility model relates to a driving mechanism of a computer sewing machine. A coupling shaft is installed at the tail end of a main shaft of the existing computer sewing machine, a disk-shaped connecting cover for an upper shaft belt pulley, a tubular upper shaft belt pulley, etc. are fixed and sheathed on the coupling shaft, and a main shaft of a sewing machine is dragged to rotate by a motor which is vertically connected with the main shaft of the sewing machine and arranged under a bedplate of the sewing machine. The upper shaft belt pulley of the main shaft is tubular, so a photoelectric coder is arranged on the coupling shaft of the main shaft, and the coder which is fixed on a machine head with a T-shaped fixed seat can be rotated simultaneously with the machine. Accordingly, the utility model can be driven by a motor with low cost in a dragging mode, and can achieve the speed regulating accuracy of direct drive. Besides, the utility model has the advantages of convenient turnover and regulation for the whole machine head, etc.
Description
The utility model belongs to the transmission mechanism field of sewing machine.
Computer control high speed sewing machine is the main equipment of rag trade, and its transmission mechanism is made up of monitoring sensor, motor and driving parts.As adopt the direct transmission computer controlled sewing machine of servomotor main shaft, and though structure is simple, specification requirement height, fetch long price.If adopt variable-speed motor to drag machine spindle by general belt composition, then monitoring sensor installation site and belt pulley axial separation, machine volume increase.When regulating, head to remove protector when opening, operation inconvenience, and the complete machine outward appearance is not attractive in appearance yet.
The purpose of this utility model is that the transmission mechanism structure that makes motor drag main shaft reaches the easy to operate requirement of compact conformation by the shape that changes machine components and the method for installation site.
Feature of the present utility model is to load onto coupling spindle at the machine spindle tail end, and puts the connection cover of shaft pulley on the porose disc in center, refills shaft pulley on the tubulose.Motor drags shaft pulley on the above-mentioned tubulose by V belt, makes the Sewing machines rotation work.Detect the purpose that axle transient speed and corner are measured on the Sewing machines in order to reach, put optical electric axial angle encoder on the coupling spindle on tubulose in the shaft pulley hole, encoder is packed in an end of encoder T shape holder by bolt, the other end of holder is by being bolted on the head of sewing machine, encoder both can be obtained signal with the synchronous rotation of machine spindle like this, can upwards overturn with head of sewing machine again and regulate the Sewing machines rotating speed, except that motor, whole device all is contained in the Sewing machines protective cover.
The advantage of this mechanism is that encoder is contained on the coupling spindle of the machine spindle in the tubulose upper belt pulley, can rotate synchronously together, the signal transmission is correct, and motor becomes arrangement up and down with last shaft pulley, above shaft pulley of institute and encoder are all in protective cover, the upset head need not the dismounting protective cover, and is easy to operate, can reach the direct drive specification requirement of servomotor.The utility model is applicable to common computer Sewing machines, computer button attaching machine and computer bar tacking machine etc.
Accompanying drawing 1 is the utility model structural representation, shown in the figure:
1. go up the disc connection cover of shaft pulley; 2. go up shaft pulley; 3. optical electric axial angle encoder; 4. encoder holder; 5. belt; 6. Sewing machines fuselage; 7. platen; 8. motor belt pulley; 9. motor; 10. carriage.
Below be embodiment in conjunction with the accompanying drawings.On the high speed button attaching machine of the computer of GE series control and high speed bar tacking machine main shaft tail end, install a coupling spindle, put shaft pulley connection cover 1 on the porose disc in center at the head end (free end) of coupling spindle, connection cover 1 is fixed by bolts on the coupling spindle, and load onto shaft pulley 2 on the cylindrical tubular by bolt, the trapezoid cross section belt grooves that on belt pulley 2 circumferential surfaces, has a circumference to be provided with.Motor 9 is packed in the below of sewing machine table 7 by frame 10, and motor drives by belt 5 and goes up shaft pulley 2 and make the machine spindle transmission.Optical electric axial angle encoder 3 should become axially to be enclosed within on the coupling spindle in the shaft pulley on the tubulose 2, make encoder can with coupling spindle and machine spindle Synchronous Transmission, and must not collide with last shaft pulley, encoder is packed on the T shape coding holder 6 by bolt, T shape coding holder 6 is processed by metallic plate, the upper lateral position is used for fixing encoder, directly curve the right angle to the position, head end is fixed by bolts on the head of sewing machine, and should not bump, can reach high accuracy speed governing and easy to operate requirement like this with rotatable parts.
Claims (2)
1. the transmission mechanism of computer controlled sewing machine, form by motor, belt and belt pulley etc., it is characterized in that being hinged with a coupling spindle at the machine spindle tail end, be with a disc connection cover 1 that the centre is porose on the coupling spindle, connection cover 1 is fixed by bolts on the coupling spindle, and by shaft pulley 2 on tubulose of bolt tipping, the trapezoid cross section belt grooves that on belt pulley 2 circumferential surfaces, has a circumference to be provided with; Motor 9 is packed in sewing machine table 7 belows by frame 10, and belt 5 passes the belt pulley 8 that platen 7 connects belt pulley 2 and motor 9.
2. transmission mechanism as claimed in claim 1, it is characterized in that on tubulose, axially being with on the coupling spindle in the shaft pulley 2 optical electric axial angle encoder 3, encoder and machine spindle rotate synchronously, encoder 3 is by being bolted to the upper lateral position of T shape encoder holder 6, holder 6 directly then curve the right angle to the position, head end is fixed by bolts on the head of sewing machine.
