The upper Kun faces of Kun 5 are held highly higher than sealing magnetic stripe 4, ensure that supporting Kun 5 can prop sealing steel band 3 so that sealing steel band 3 with
The upper surface separation of bar shaped sliding slot 10, so that slide 2 can slide on bar shaped sliding slot 10, and supporting Kun 5 makes sealing steel band 3
Sliding friction between slide 2 is rolling friction so that the movement of slide 2 is more smoothly, and reduces energy loss, reduces
Abrasion between slide 2 and sealing steel band 3, avoids slide 2 and seals the heat that is produced by friction between steel band 3, it is preferable that
Slide 2 in the present embodiment is equipped with two supporting Kun 5 being arranged side by side.
Further, the linear motor further includes pressure Kun 6, and the slide 2 is respectively provided with least at the both ends of glide direction
The one pressure Kun 6, the sealing steel band 3 are arranged on the pressure Kun 6 close to the side of the slide unit 1；
The lower Kun faces of the pressure Kun 6 are less than the upper Kun faces of the supporting Kun 5.
In the present embodiment, it is the cylinder that own axis can be surrounded on slide 2 to press Kun 6, presses the lower Kun faces of Kun 6
Less than the upper Kun faces of supporting Kun 5, and Kun 6 is pressed to be arranged on the both sides for supporting Kun 5 so as to be arranged in the sealing steel band 3 in slide 2 in cunning
Also have on seat 2 while arch upward a upper surface to bar shaped sliding slot 10 close to trend, further increase sealing steel band 3 with
Sealing area between bar shaped sliding slot 10, enhances sealing effect of the sealing steel band 3 to bar shaped sliding slot 10, while causes sealing steel
For band 3 when being punctured into slide 2, upper and lower surface forms rolling friction with slide 2, its effect has been described above, herein not
Repeat again.
Specifically, height when pressing the lower Kun faces of Kun 6 to be bonded with the upper surface of sealing steel band 3 and bar shaped sliding slot 10 is identical.
Ensure that through pressure Kun 6 sealing steel band 3 be close to the upper surface of bar shaped sliding slot 10, as much as possible increase seal steel band 3 with it is close
The magnetic area between magnetic stripe 4 is sealed, ensures the sealing effect of sealing steel band 3.
Further, the Kun long of Kun 6 is pressed to be greater than or equal to the width of sealing steel band 3 so that pressure Kun 6 is to sealing steel band 3
It is more preferable to roll effect, prevents sealing steel band 3 from deforming.
Further, the width of slide 2 be greater than or equal to sealing steel band 3 width, and the width of slide 2 also greater than or wait
In the length of pressure Kun 6 so that pressure Kun 6 is non-bulging in slide 2 so that the appearance of slide 2 is more complete.
Further, the linear motor further includes slide lid 7, and the slide lid 7 is arranged on the slide 2, by institute
The supporting Kun 5 and pressure Kun 6 is stated to be contained among the slide lid 7.
In the present embodiment, slide lid 7 is the housing of lid, by the way that supporting Kun 5 and pressure Kun 6 are contained in slide lid 7
So that the structure of slide 2 is more complete, while the slide lid 7 added effectively prevent dust and other impurities to supporting Kun 5 and pressure
The influence of Kun 6, plays the role of protection to supporting Kun 5 and pressure Kun 6.
Further, Kun 5 is supported and/or presses the surface of Kun 6 to be equipped with silica gel, in the present embodiment, supporting Kun 5 and pressure Kun 6
Surface be equipped with silica gel, silica gel has soft characteristic, is not easy to be corroded.Using the soft characteristic of silica gel matter, Kun 5 and pressure are supported
Kun 6 reduces supporting Kun 5 and presses Kun 6 and seal the noise produced between steel band 3 by friction when being rolled on sealing steel band 3,
So that the operating noise smaller of the linear motor.Meanwhile the lower Kun faces of Kun 6 are pressed to be slightly less than sealing steel band 3 and bar shaped sliding slot 10
Fitting when height.And since silica gel has elasticity, when pressing Kun 6 to press to sealing steel band 3, there occurs one in the female face of pressure Kun 6
Fixed deformation, so as to generate an elastic-restoring force, sealing steel band 3 is further pressed on sealing magnetic stripe 4 by elastic-restoring force
On, it further enhancing the sealing effect of sealing steel band 3.
Further, the linear motor further includes sealing magnetic stripe 4, and the sealing magnetic stripe 4 is arranged on the bar shaped sliding slot 10
Edge, it is described sealing steel band 3 by it is described sealing magnetic stripe 4 the bar shaped sliding slot 10 is sealed.
In the present embodiment, the magnetic-type connection by sealing magnetic stripe 4 with sealing steel band 3 so that seal steel band 3 by bar shaped
Sliding slot 10 covers, and bar shaped sliding slot 10 is sealed, and due to sealing steel band 3 and seals the magnetic characteristic between magnetic stripe 4 so that be inserted in
Sealing steel band 3 on slide 2 adsorbs in addition to the part propped by slide 2 with sealing magnetic stripe 4, ensures that sealing steel band 3 begins
Bar shaped sliding slot 10 seals at last, while the reciprocating motion without prejudice to slide 2 on bar shaped sliding slot 10 again.
Specifically, the thin plate that steel band 3 is strip is sealed, sealing magnetic stripe 4 is on the both sides of the edge of bar shaped sliding slot 10
Bar magnet, it is more firm to seal the connection between 1 body of magnetic stripe 4 and slide unit, can be in sealing magnetic stripe 4 and slide unit 1
Gluing between body.
It is appreciated that sealing steel band 3 and the size of magnetic area sealed between magnetic stripe 4 determine, sealing steel band 3 with it is close
Seal the size of the magnetic attraction between magnetic stripe 4, the size of magnetic attraction affects the leakproofness of sealing steel band 3 again and slide 2 slides
Smooth degree, therefore suitable magnetic area need to be selected according to various factors.
Further, the both ends of the sealing steel band 3 offer mounting hole 301, will be described close by the mounting hole 301
The both ends of envelope steel band 3 are fixed on the slide unit 1.
Further, mounting hole 301 is waist-shaped hole, and the both ends of sealing steel band 3 are worn by fastening screw hole or other fixing pieces
Waist-shaped hole is crossed to be connected on slide unit 1.Waist-shaped hole is the hole of strip, and the trip bolt being connected on waist-shaped hole can be in waist-shaped hole
Upper movement, so that the length of sealing steel band 3 has certain controlled variable.
Further, the linear motor further includes two fixinig plates 31, which corresponds to waist-shaped hole and offer respectively
Mounting hole, sets the fixinig plate 31, increases the contact area of trip bolt or other fixing pieces and sealing steel band, reduces sealing steel
With suffered pressure, deformation is reduced, is conducive to preferably fixing seal steel band.
The above is only the preferred embodiment of the present invention, and it does not limit the scope of the patent of the present invention,
It is every under the inventive concept of the utility model, equivalent structure made based on the specification and figures of the utility model becomes
Change, or directly/be used in other related technical areas indirectly and be included in the scope of patent protection of the utility model.
