Detailed description of the invention
For making those skilled in the art better understand the technical solution of the utility model, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 2 and Fig. 3 is respectively left view and the top view of embodiment scraping teeth device.Can find out from Fig. 2 and Fig. 3 that scraping teeth device comprises device body 1, scraping teeth is turned the 2, first axis 3 and spring 4.
Fig. 4 is the axonometric drawing of embodiment scraping teeth device.As can be seen from Figure 3, device body 1 has groove 14, groove 14 is rectangular recess, and scraping teeth is turned and 2 can be inserted in groove 14.
Scraping teeth 2 first ends comprising the first arm 22 and the second arm 21, first arm 22 of turning are fixedly connected with the first end of the second arm 21.In the present embodiment, the first arm 22 and the second arm 21 angle are 90 °.The angle of certain first arm 22 and the second arm 21 also can be other angles, but considers from practical application angle, and its angle is preferably and is more than or equal to 90 °.
Device body 1 have two coaxial the first through holes 11, turn first arm 22 of 2 and the connecting portion of the second arm 21 of scraping teeth has the second through hole 25 (the second through hole cannot embody in the diagram, can find out in Fig. 5), first axis 3 turns 2 through the first through hole 11 and the second through hole 25 connectable unit body 1 and scraping teeth, scraping teeth is turned and 2 to rotate relative to the first axis 3.
Scraping teeth turn 2 the end of the first arm 22 there is scraping teeth head 24, as can be seen from Figure 2 scraping teeth head 24 scrape the bottom surface that increment can spill device body 1, play the effect that clamping remains tooth.
In the present embodiment, device body 1 has fourth hole 15, fourth hole 15 can connect the 3rd axis; Second end of the second arm 21 has third through-hole 23, third through-hole 23 can connect the second axis, second axis and the 3rd axis linking springs 4, make spring can make scraping teeth turn 2 and device body 1 there is certain pulling force, what ensure to scrape scraping teeth head 24 on dentate body scrapes increment exposing device body, the residual tooth on slide fastener can be struck off; And at normal zipper segment, because spring force quantity not sufficient is to take up slide fastener tooth, therefore scraping teeth rotary head 2 rotates, make to scrape increment 24 and streak at normal slide fastener surface.
In other embodiments, other elastic component also can be adopted to connect the second arm 21 and the device body 1 of scraping teeth rotary head 2.From principle angle consider, arrange third through-hole 23, fourth hole 15, second axis, the 3rd axis object be facilitate spring to connect, the structure that certainly also can be set to other plays connection function.
On device body 1, also have fifth hole 13 as can be seen from Figure 4, fifth hole has penetrated first through hole 11 on device body.On the first axis 3, the position corresponding with fifth hole 13 has screwed hole, through the screwed hole on fifth hole and the first axis 3, first axis 3 is fixed on device body 1 by screw, ensure that the first axis 3 can not rotate relative to device body, guarantee the normal rotation of scraping teeth rotary head 2.
Certainly, other fixed form also can be adopted to fix the first axis 3, or make the first axis 3 for the form of interference fit, relative rotation can not occur with the first through hole 11.
From Fig. 4, also can find out also have bolt hole 12 on device body 1, scraping teeth device can be fixed on head penetrating machine by bolt passing through bolt hole.Certainly, from practical standpoint, before scraping teeth device must be installed on head penetrating machine body of work part.And the lower surface of head penetrating machine and scraping teeth device should have certain space can ensure that scraping teeth head 24 can rotate, make slide fastener by corresponding space.
Fig. 5 is the A-A face sectional view in Fig. 3.As can be seen from Figure 5, scraping teeth is turned and is had the second through hole 25, first axis 3 on 2 and can pass the first through hole 25.It should be noted that in the present embodiment, the first axis 3 and the second through hole 25 are matched in clearance, ensure that scraping teeth is turned and 2 can to rotate relative to the first axis 3.Certainly in other embodiments, if the first axis 3 and the second through hole 25 are interference fit, then should ensure that the first axis 3 and the first through hole 11 are matched in clearance.
As can be seen from Figure 5, the increment of scraping of the scraping teeth head 24 in the present embodiment is acute angle.Consider from the angle used, as long as scrape increment can fasten corresponding residual tooth, acute angle is not the architectural feature of necessity, but acuter angles can save space, and what can arrange multiple scraping teeth head 24 at respective regions scrapes increment.Shall also be noted that as can be seen from Figure 2, there are in the present embodiment two scraping teeth heads 24; Certainly, the speed of service of the quantity of the scraping teeth head situation and zipper strip that also can remain tooth according to reality is determined.
Also can find out that scraping teeth head 24 has through hole, scraping teeth turn 2 the first arm 22 end also there is screwed hole, scraping teeth head 24 is connected by screw turns on 2 at scraping teeth.Certainly, scraping teeth head 24 and scraping teeth are turned and 2 also be can be integrated structure.
Fig. 6 is the schematic diagram of embodiment scraping teeth device scraping teeth.When using this scraping teeth device as shown in Figure 6, slide fastener moves to the right on the left of Fig. 6, and scraping teeth head 24 clamping remains tooth, because the adhesion of residual tooth and zipper strip is less, the pulling force being not enough to overcome spring 4 makes scraping teeth turn 2 rotations, and therefore residual tooth is eliminated; And the adhesion of the dental part of normal condensation is comparatively large, can overcome the pulling force of spring 4, therefore scraping teeth is turned 2 generation rotating cylinders, and scraping teeth head 24 is streaked at normal slide fastener surface.
Fig. 7 is the situation of practical this scraping teeth device rear zipper band muscle, can find out tooth residual after adopting this device can remove surely very little mill teeth, facilitate follow-up penetrator to operate.
Scraping teeth device in above the utility model embodiment is described in detail.Apply specific case herein to set forth principle of the present utility model and embodiment; the explanation of above embodiment just understands core concept of the present utility model for helping; when not departing from the utility model principle; also can carry out some improvement and modification to the utility model, these improve and modify and also fall in protection domain of the present utility model.
