In addition, there is the dealer to release the Sewing machines of adopting direct drive motor recently, when being a kind of dispatching from the factory, it establishes the type that direct-drive motor replaces the conventional belt kind of drive in sewing machine head, but this kind adopting direct drive motor Sewing machines does not have the member of heat radiation aspect, reduce the hot gas that the direct-drive motor running produces but directly brush with the Industrial fan in the work factory building, but this kind mode also can't reach the comprehensive heat radiation of motor, only there is the one side that is blown to by fan to have the effect of cooling heat dissipation, so still desirable not to the utmost on the radiating efficiency.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of high temperature that can be produced at direct-drive motor running and the direct-drive motor heat sink of the industrial sewing machine that dispels the heat at above-mentioned prior art.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: the direct-drive motor heat sink of this industrial sewing machine, it is characterized in that: the corresponding group of rear-end of spindle at the direct-drive motor of sewing machine table power input is established a handwheel, and handwheel one side is provided with plural steam vent, and the inner corresponding assembling one ring limit tool of handwheel is established the radiator fan of flow deflector, be linked to the handwheel place at the outside sheathed shell of direct-drive motor in addition, by forming flow-guiding channel between direct-drive motor surface and shell.
By this, utilize radiator fan that the high temperature that direct-drive motor produced is evacuated via the steam vent of handwheel, allow flow-guiding channel form cross-ventilated pipeline simultaneously, reach better radiating effect, to guarantee the service life of direct-drive motor.
Described handwheel is provided with to distribute on the side of steam vent and is provided with spiral shell and establishes the hole, and then correspondingly in the radiator fan place is provided with the perforation of establishing the hole winding with the handwheel spiral shell.
The corresponding direct-drive motor of described enclosure colludes the groove place and is provided with the convex clip that shell can be installed in the direct-drive motor outside and colludes.
Compared with prior art, the invention has the advantages that:
1, the direct-drive motor heat sink of industrial sewing machine of the present invention owing to be provided with radiator fan at the side of direct-drive motor, looses with the high temperature row who the direct-drive motor running is produced in good time, reaches better radiating effect, to guarantee the service life of direct-drive motor.
2, the direct-drive motor heat sink of industrial sewing machine of the present invention utilizes to organize on main shaft and establishes handwheel, and the mat handwheel comes corresponding assembling radiator fan again, its radiator fan is rotated synchronously with main shaft dispel the heat, and reaches best radiating effect.
3, the direct-drive motor heat sink of industrial sewing machine of the present invention, utilize the lip-deep groove that colludes of direct-drive motor to cooperate the formed space of shell and constitute flow-guiding channel, when allowing direct-drive motor running heat radiation, can suck cold air simultaneously and keep cross-ventilation that hot-air is able to spilling out, allow the effect of heat radiation reach optimum state.
4, the direct-drive motor heat sink of industrial sewing machine of the present invention utilizes the different spindle rotating directions that come corresponding direct-drive motors of the set direction of the flow deflector of radiator fan, but and forms the heat radiation function of a water conservancy diversion.

The specific embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
Embodiment one:
At first, see also Fig. 1～shown in Figure 3, for the solid of the direct-drive motor heat sink embodiment one of industrial sewing machine of the present invention is decomposed, combination and combination cross-sectional schematic, it mainly is to establish a handwheel 2 in the corresponding group in main shaft 11 rear ends of the direct-drive motor 1 of sewing machine table power input, it is mutually sheathed with main shaft 11 that these handwheel 2 centers are provided with a perforation 23, perforation 23 ring peripheries have a screwed hole 231 and establish part 24 spiral shells for a spiral shell and establish, and handwheel 2 one sides are provided with plural steam vent 21 and spiral shell is established hole 22, and encircle the radiator fan 3 that the limit tools are established flow deflector 31 by handwheel 2 inner corresponding assemblings one, and establish hole 22 is corresponding and radiator fan 3 medial surfaces are set perforation 32 mat screw tightenings 33 windings together with the spiral shell of handwheel 2, be linked to handwheel 2 places in direct-drive motor 1 an outside sheathed shell 4 in addition, this shell 4 inner corresponding direct-drive motors 1 surface is colluded groove 12 places and is provided with convex clip and colludes 41, to reach shell 4 is installed in direct-drive motor 1 outside by this.
