Abstract

The invention relates to a heat dissipation structure for a hidden direct-drive motor of a sewing machine. The structure mainly comprises a body, a main shaft of the body, a compartment, an air inlet and an air outlet, wherein a lower body of the body is provided with the compartment capable of receiving a transmission structure, while the bottom is provided with a bottom board of the air inlet; the rear part of the main shaft of the body is directly and serially provided with the drive motor; a heat dissipation vane wheel is arranged between the drive motor and the main shaft of the body; the compartment is arranged behind the lower body of the body, and is provided with an opening so as to ensure that the front segment of the drive motor can be driven and the heat dissipation vane wheel can extend into the compartment for assembly; the air inlet is arranged on the side wall of the compartment of the body; and the air outlet is arranged on the periphery of the opening of the compartment. Therefore, the drive motor can be directly connected and hidden in the compartment arranged behind the lower body of the body so as to reduce the assembly space; and the heat dissipation vane wheel can be linked in operation, and excellent heat dissipation can be achieved by sucking air by the air inlet and blowing air by the air outlet so as to protect the motor from damage due to overheat.

Description

Heat dissipation structure for hidden direct-drive motor of sewing machine

Technical field

The present invention is about a kind of heat dissipation structure for hidden direct-drive motor of sewing machine, espespecially utilize simplify draw the concealed driving member, reach the purpose that reduces production costs, make the Sewing machines assembling more easy, during the CD-ROM drive motor running, body is more firm, simultaneously have again good radiating effect, it is more durable that can effectively increase product service life.

Background technology

Sewing machines is the indispensable capital equipment of rag trade, early stage traditional Sewing machines needs to trample by manpower the normal operation that can keep machine, with the epoch progressive at present no matter industrial or seam You machine household small-size all to have adopted automatic motor be its power, not only more convenient in manufacturing operation, and machine is advanced also more smooth and easy stable, and the sewing quality is obviously significantly promoted.

In addition, for meeting the demand on various clothing sewings, traditional Sewing machines is also by original simple structural design, and derive the machining machine and tool of various different specific functions, under its Related product is is in the industry cycle constantly actively researched and developed, always existing many improvement, and application gets permission to obtain patent.

Although each functional structure of Sewing machines of the formula of habit improves progress always, but its drive motor be still be configured under machine table top in the majority, because motor configurations below, so must add on machine table top and cut open the hole, can be connected for wearing with transmission main shaft on belt, structure is walked distance and is taken up space, and whole transmission mechanism cost is higher, links configuration also comparatively complicated.And drive motor when running be easily because of stressed improper generation heating, but and do not have good heat dissipation design on it, therefore Chang Yinwei excess Temperature and breaking down.

Summary of the invention

Be the above-mentioned existing disappearance of Sewing machines of commonly using of forgoing, the invention provides a kind of heat dissipation structure for hidden direct-drive motor of sewing machine, by the driving member of simplifying, make the Sewing machines assembling more easy, reach the purpose that reduces production costs, and make CD-ROM drive motor when running more firm, have again good radiating effect simultaneously, it is more durable that can effectively increase product service life, is the technology emphasis place that institute of the present invention wish solves.

For reaching aforementioned purpose, a kind of heat dissipation structure for hidden direct-drive motor of sewing machine that the present invention is designed, it mainly comprises: a body, its lower body be provided with can accommodating drive mechanism compartment, the bottom is provided with the base plate of air inlet; One body main shaft, its rear directly string are established a CD-ROM drive motor, and are provided with heat-dissipating impeller between CD-ROM drive motor and body main shaft; One compartment is located at the rear of body, and it has an opening and stretches into assembling for CD-ROM drive motor leading portion and heat-dissipating impeller; One air inlet is located on the base plate of body compartment, and; One air outlet is located at the periphery of compartment opening.

Wherein, be connected in series by an axle sleeve between this motor drive shaft and body main shaft fixing; Being provided with prominent hole sheet in compartment fixes for the CD-ROM drive motor interlocking.

Wherein, this air inlet is the transom window of a porous; And this air outlet is consisted of by the porosity chart that a spacer ring is located at compartment opening periphery.

By this, CD-ROM drive motor can directly be connected be configured on body, dwindling interblock space, and heat-dissipating impeller can interlock during running, is blown out by air inlet is air-breathing the heat radiation that reaches good by air outlet, avoids cause thermal damage with the protection CD-ROM drive motor.

For enabling further to understand constitution content of the present invention and other characteristics, hereby lift the present invention than specific embodiment, and coordinate the embodiment of accompanying drawing to describe in detail as described below.

Fig. 2: be three-dimensional exploded view of the present invention.

Fig. 3: be the rearview of body of the present invention.

Fig. 4: be application illustration of the present invention.

The specific embodiment

See also Fig. 1～shown in Figure 4, a kind of heat dissipation structure for hidden direct-drive motor of sewing machine that the present invention is designed, it mainly comprises:

One body 10, its lower body rear be provided with can accommodating drive mechanism compartment 40, the bottom is provided with the base plate 42 of air inlet 50;

One body main shaft 20, its rear directly string are established a CD-ROM drive motor 30, and motor drive shaft 31 is connected in series by an axle sleeve 21 with 20, body main shaft and fixes, and is provided with heat-dissipating impeller 32 between CD-ROM drive motor 30 and body main shaft 20;

One compartment 40 is located at the lower body rear of body 10, and it has an opening 41 and stretches into assembling for CD-ROM drive motor 30 leading portions and heat-dissipating impeller 32;

One air inlet 50 is located on the base plate 42 of the corresponding compartment 40 of organism bottom; And,

One air outlet 60 is located at the periphery of compartment opening 41;

During enforcement, be provided with prominent hole sheet 43 in its compartment 40 and fix for CD-ROM drive motor 30 interlockings, this air inlet 50 is the transom window of a porous; And this air outlet 60 is consisted of by the porosity chart that a spacer ring is located at compartment 40 opening 41 peripheries.

by this, see also Fig. 3, shown in Figure 4, CD-ROM drive motor 30 configuration that can directly be connected is hidden in the compartment 40 at lower body rear of body 10 to dwindle interblock space, it is more easy that overall structure is comparatively simplified assembling, can effectively reach and reduce production costs, and more firm can make CD-ROM drive motor 30 running the time, and because the direct string of CD-ROM drive motor 30 is located at the rear of body main shaft 20, during running firm and stressed evenly and can obviously reduce heating, but and then rotation of interlock heat-dissipating impeller 32 again simultaneously, blow out by air outlet 60 radiating effect that reaches good again by air inlet 50 is air-breathing, avoid overheated damage with protection CD-ROM drive motor 30, it is more durable that can effectively increase product service life.
