Abstract
The utility model aims at providing a dustproof structure of a sewing machine motor encoder. The dustproof structure of the sewing machine motor encoder comprises a motor arranged on an upper shaft of a machine head of the sewing machine and a dustproof rear cover. The motor is arranged on the upper shaft of the right side of the machine head, and the dustproof rear cover is arranged on a rear end cover of the motor. A maze structure is arranged on the dustproof rear cover and forms a sealing dustproof space with the rear end cover of the motor. The dustproof structure of the sewing machine motor encoder has the advantages that a cavity capable of preventing dust from entering into is formed by the dustproof rear cover with the maze structure and the rear end cover of the motor, a dustproof effect is good, therefore, the service life of an electronic element is prolonged, and in addition reliability of operation of a system is improved.
Description
Technical field
The utility model relates to the sewing machine technique field, relates in particular to a kind of electrical motor of sewing machine encoder dustproof construction.
Background technology
Sewing machines is to use one or more sewing thread, forms one or more stitchings, the machine that makes one or more layers sewing interweave or unite by a seam at sewing.The application of Sewing machines is very extensive, and the motor that arranges on the existing sewing machine head, dustproof bonnet internal diameter opening is bigger, and there is bigger space between the back end cover for motor, Sewing machines work under dirty environment, dustproof weak effect, dust enters easily, reduce components and parts service life, reliability of system operation reduces.
In sum, existing sewing machine motor encoder dustproof also existence can further improved place; Therefore, need a kind of electrical motor of sewing machine encoder dustproof construction especially, to solve the above-mentioned existing problem that exists.
The utility model content
The purpose of this utility model is to provide a kind of electrical motor of sewing machine encoder dustproof construction, and at the defective that present technology exists, dustproof bonnet is provided with labyrinth structure, forms the good cavity that prevents dust with back end cover for motor.To solve above-mentioned problems of the prior art.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of electrical motor of sewing machine encoder dustproof construction is characterized in that, it comprises motor and the dustproof bonnet that is arranged on axle on the head of sewing machine; Described motor is installed in axle on the head right side, and described dustproof bonnet is installed in motor rear end and covers;
In a preferred embodiment of the present utility model, described sewing machine head motor is provided with rear end cap, and described dustproof bonnet is provided with labyrinth structure, forms the good cavity that prevents dust with back end cover for motor.
A kind of electrical motor of sewing machine encoder dustproof construction of the present utility model has following advantage:
(1) dustproof bonnet is provided with labyrinth structure, forms the good cavity that prevents dust with back end cover for motor.Has well dustproof effect.
(2) prolong electronic devices and components service life, and then improve reliability of system operation.
A kind of electrical motor of sewing machine encoder dustproof construction of the present utility model is compared with present product, has changed the design of dustproof bonnet, forms the good cavity that prevents dust with the motor bonnet, realizes the purpose of this utility model.
Characteristics of the present utility model can be consulted the detailed description of the graphic and following better embodiment of this case and be obtained to be well understood to.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is a kind of electrical motor of sewing machine encoder dustproof construction partial sectional view of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, further set forth the utility model below in conjunction with specific embodiment.
Referring to Fig. 1, a kind of electrical motor of sewing machine encoder dustproof construction of the present utility model, it comprises the motor that is arranged on axle on the head of sewing machine, motor is provided with rear end cap 1, is installed in the dustproof bonnet 2 on the back end cover for motor 1.
Back end cover for motor 1 is fixed on the motor shaft 3.
Be provided with handwheel 5, packing ring 4, dustproof bonnet 2, encoder circuit plate 6 above the back end cover for motor 1; Handwheel 5, packing ring 4 are fixed on the motor shaft 3 by screw; Dustproof bonnet 2 is fixed on the back end cover for motor 1 by screw, forms a dustproof good cavity; Encoder circuit plate 6 is fixed in this inside cavity by screw.Thereby realize the good dust-proof effect.
In a preferred embodiment of the present utility model, described sewing machine head motor is provided with rear end cap, and described dustproof bonnet is provided with labyrinth structure, forms the good cavity that prevents dust with back end cover for motor.Make the dustproof effect of motor encoder improve, thereby prolong components and parts service life, improve reliability of system operation.
