The content of the invention
The purpose of the present invention is in view of the above-mentioned problems existing in the prior art, it is proposed that a kind of compression whirler of sewing machine
Structure, the technical problem of solution is the stable operation for how making mechanism ensure mechanism while realizing and compressing and rotate.
The purpose of the present invention can be realized by following technical proposal：
Rotary shaft, the rotation are equipped with the compression rotating mechanism of sewing machine, including mounting seat and template, the mounting seat
The lower end of rotating shaft is fixedly connected with template, and motor is fixed with the mounting seat, phase is provided between the motor and rotary shaft
The driving wheel and driven pulley mutually engaged, the rotating shaft of the motor is fixedly connected with driving wheel, it is characterised in that the follower shaft
To being fixed in mounting seat, the center of the driven pulley is axially through there is mounting hole, and the rotary shaft is located in mounting hole
It is interior and circumferentially fixed with driven pulley, actuator is connected with the rotary shaft, the actuator drives rotary shaft in mounting hole
Slide up and down.
The lower end of rotary shaft is fixed with template, can make template that the sewing on platen is pressed on into platform when rotary shaft declines
On plate, rotary shaft can be rotated when rotating with template and sewing on platen.Rotary shaft is driven to install when actuator works
Slided up and down in hole, realize the lifting of rotary shaft, mechanism is realized compression；Driving wheel is driven to rotate so as to band when motor works
Dynamic driven pulley is rotated, and driven pulley, which is rotated, drives rotary shaft to rotate, and mechanism is realized rotation.Rotary shaft and driven pulley are circumference
Fixed, rotary shaft can axially be slided in mounting hole.Because actuator only drives rotary shaft in the mounting hole of driven pulley
Inside slide up and down, it is not necessary to load motor, driven pulley and driving wheel so that cylinder operation is stable and is imitated with higher work
Rate, so as to ensure the stable operation of mechanism.
In the compression rotating mechanism of above-mentioned sewing machine, the actuator include being fixed on cylinder in mounting seat and
The spring between mounting seat and rotary shaft is arranged on, the cylinder drives rotary shaft upward sliding in mounting hole, the spring
Rotary shaft slide downward in mounting hole is driven, the piston rod of the cylinder is fixedly connected with the upper end of rotary shaft, the cylinder
Piston rod and rotating shaft coaxle set.
During cylinder charge, motion lifts template to the piston rod of cylinder upwards；After cylinder is deflated, work of the rotary shaft in spring
Moved downward under and the sewing on platen is pressed on platen.Cylinder coordinates spring works to can be realized as compressing rotating mechanism
Automatic impaction, make the operating efficiency of mechanism high.When in platen motion up-down vibration occurs for template, because spring can be automatic
Absorb or release vibrational energy, be difficult mechanism affected by vibration, make mechanism stable.The piston rod of cylinder and rotary shaft are same
Axle is set, it is possible to reduce friction when rotary shaft rotates between piston rod and cylinder block, so as to ensure the performance of cylinder
And service life, it is ensured that the stable operation of mechanism.
In the compression rotating mechanism of above-mentioned sewing machine, the spring is set in rotary shaft, in the rotary shaft also
Back-up ring one and back-up ring two are arranged with, the back-up ring two is fixed on the rotary shaft, and the top and bottom of the spring are born against
On back-up ring one and back-up ring two, the back-up ring one is resisted against in mounting seat, and the back-up ring one can be slided up and down on the rotary shaft.

Wheel 5 and driving wheel 4 so that the working stability of spring 13, so as to ensure the stable operation of mechanism.Above and below template occurs on platen
During vibration, due to spring 13 can automatic absorption or release vibrational energy, up-down vibration will not destroy the performance of spring 13, make machine
Structure is difficult affected by vibration, makes mechanism stable.This compression rotating mechanism is by motor 3, cylinder 6 and spring 13 to same
Axle is that rotary shaft 2 is rotated and oscilaltion so that compression rotating mechanism is simple in construction, and stability during work is good.This pressure
Tight rotating mechanism ensure that the stable operation of mechanism while realizing and compressing and rotate.
Embodiment two
As shown in Figure 7 and Figure 8, actuator includes cylinder 6, and the driving of cylinder 6 rotary shaft 4 is slided up and down in mounting hole 5a.
It is arranged with back-up ring 1, spring 13 and back-up ring 2 14, back-up ring 1, spring 13 and back-up ring two in rotary shaft 2 successively from top to bottom
14 are respectively positioned in cavity of resorption 1a2, and the top and bottom of spring 13 are born against on back-up ring 1 and back-up ring 2 14, and back-up ring 1 is consolidated
Be scheduled in rotary shaft 2, the lower surface of back-up ring 2 14 be resisted against three 1d of perforation on along upper, back-up ring 2 14 can be in rotary shaft 2
Slide up and down.When rotary shaft 2 declines, the lower surface of back-up ring 2 14 be resisted against three 1d of perforation on along upper, back-up ring 2 14 relative to
Rotary shaft 2 is moved upwards, and spring 13 is compressed.When rotary shaft 2 declines, spring 13 has cushioning effect, can make under rotary shaft 2
Template be smoothly pressed on sewing, make mechanism stable.Other structures are identical with embodiment one.
The piston rod of cylinder 6, which moves up and down, drives rotary shaft 2 to be slided up and down in the mounting hole 5a of driven pulley 5, works as rotation
Axle 2 can make template that the sewing on platen is pressed on platen when declining.The axis of rotation of motor 3 drives driving wheel 4 to rotate,
Driving wheel 4 is engaged with driven pulley 5, and driven pulley 5 rotates to drive rotary shaft 2 to rotate, and rotary shaft 2 can be with template when rotating
Rotated with sewing on platen.Because 6 driving rotary shafts 2 of cylinder are slided up and down in the mounting hole 5a of driven pulley 5, it is not necessary to
Load motor 3, driven pulley 5 and driving wheel 4 so that the working stability of cylinder 6 and with higher operating efficiency, thus make mechanism
The stable operation of mechanism is ensure that while realizing and compressing and rotate.Pass through the sliding groove 5b of driven pulley 5, the cunning of rotary shaft 2
Dynamic bar 2a is set, and reduces the influence that motor 3 works to cylinder 6；By the setting of axle sleeve 1, end face bearing 8 and support set 9,
The rotation for being stablized driven pulley 5；By setting axle sleeve 2 10 and axle sleeve 3 11, make the stable rotation of rotary shaft 2；Spring is set
13 make being pressed on sewing of form stable；These settings make mechanism working stability, it is ensured that the stable operation of mechanism.This compression is revolved
Rotation mechanism is that rotary shaft 2 is rotated and oscilaltion to same axis by motor 3 and cylinder 6 so that compress rotating mechanism
Simple in construction, stability during work is good.This compression rotating mechanism is that rotary shaft 2 is entered to same axis by motor 3 and cylinder 6
Row rotation and oscilaltion so that compression rotating mechanism is simple in construction, and stability during work is good.
Specific embodiment described herein is only to spirit explanation for example of the invention.Technology neck belonging to of the invention
The technical staff in domain can be made various modifications or supplement to described specific embodiment or be replaced using similar mode
Generation, but without departing from the spiritual of the present invention or surmount scope defined in appended claims.
