Detailed description of the invention

Describe the technical solution of the utility model in detail below with reference to drawings and the specific embodiments, so as clearer, understand invention essence of the present utility model intuitively.

Shown in Fig. 1, the present embodiment provides a kind of cutter wheel device 100, transmits cutter band 200 for sponge cutting machine, so that sponge is cut. this cutter wheel device 100 comprises three fixing break bars 11, 13, 14, two mobile break bars 12, 15 and two guide rails that be arranged in parallel 16, on these five break bars, be wound with an endless knife band 200, three fixing break bars 11, 13, 14 are respectively in by wherein three end points of two guide rails 16, two mobile break bars 12, 15 lay respectively on two guide rails 16, cutter band 200 is sent to mobile break bar 12 from fixing break bar 11 successively, arrive again mobile break bar 15, then arrive fixing break bar 14, arrive again fixing break bar 13, finally get back to fixing break bar 11, whole cutter band 200 structure ringwise, by this five break bar tensionings and transmission.

Shown in Fig. 1 and Fig. 2, two mobile break bars 12,15 are all arranged on the moving plate 17 of a title, claim moving plate 17 to be suitable for sliding on guide rail 16, and drive mobile break bar 12 and 15 to move, claim that on moving plate 17, being respectively provided with one turns round blade insert 18, turning round blade insert 18 for these two is oppositely arranged, cutter band 200 is wrapped on mobile break bar 12 and 15 through after turning round blade insert 18, turn round blade insert 18 be suitable for the cutter band 200 to rotate to change along an axis of length direction that is parallel to cutter band 200 cutter band 200 blade towards, to change cut direction.

The above-mentioned blade insert 18 of turning round is fixed on a movable plate 171, between the moving plate 17 of movable plate 171 and title, is provided with slide rail 172 and slide block 173, between the moving plate 17 of movable plate 171 and title, produces relative motion by slide block 173 in the interior slip of slide rail 172. One end of movable plate 171 is also connected on the output shaft of a cylinder 174, is driven by this cylinder 174, movable plate 171 is driven and turn round blade insert 18 with respect to claiming that moving plate 17 makes stretching motion, with the length that regulates two to turn round the cutter band 200 between blade insert 18. Like this, can be adapted to the sponge cutting of different in width, in the time that sponge is wider, can utilize cylinder 174 to pull movable plate 171, make to turn round blade insert 18 and retract, thereby increase two length of turning round the cutter band 200 between blade insert 18, otherwise, promote movable plate 171 and make to turn round blade insert 18 and stretch out, thereby reduce two length of turning round the cutter band 200 between blade insert 18. The length of this section of cutter band 200 is less, and cutter band 200 is more stable is difficult for waving, thereby can increase the cutting speed of cutter band 200, is conducive to improve cutting efficiency.

Between slide rail 172 and slide block 173, adopt engagement connection mode, make slide rail 172 and the slide block 173 only can relative sliding, and can not throw off while sliding, thereby without extra fixed connection structure or position limiting structure, thereby make structure more simple and reliable.

Shown in Fig. 3 and Fig. 4, in the present embodiment, turn round blade insert 18 and comprise CD-ROM drive motor 181, gear reduction unit 182, bearing 183 and folder cutter stone 184, wherein, CD-ROM drive motor 181 is fixed on movable plate 171 by a fixed head 185, and drives folder cutter stone 184 to rotate by gear reduction unit 182. Bearing 183 is arranged between described folder cutter stone 184 and movable plate 171, with holding clamp cutter stone 184. Be specially, bearing 183 has bearing holder (housing, cover), bearing holder (housing, cover) is fixed on movable plate 171 by a fixed head 185, one end of bearing 183 is provided with gear wheel, pinion composition said gear decelerator 182 on gear wheel and CD-ROM drive motor 181, the other end connects folder cutter stone 184, and drives folder cutter stone 184 to rotate.

Be preferably, above-mentioned CD-ROM drive motor 181 is servo motor, can input as required corresponding control signal, to control the rotational angle of CD-ROM drive motor 181, according to the gearratio of gear reduction unit 182, can draw the rotational angle of folder cutter stone 184 again, be also the rotational angle of cutter band 200. Conversely, if need make cutter band 200 rotate predetermined angular, can instead push away the angle of CD-ROM drive motor 181 required rotations, thereby input controls signal to CD-ROM drive motor 181 accordingly.

Bearing 183 comprises bearing holder (housing, cover) (not shown), and this bearing holder (housing, cover) is fixedly connected with folder cutter stone 184, and drives folder cutter stone 184 to rotate.

Said gear decelerator 182 is spur gear two stage reducer. This gear reduction unit 182 comprises gear wheel and pinion, and pinion is connected with the output shaft of CD-ROM drive motor 181, and gear wheel is arranged at the outer surface of bearing holder (housing, cover).

In addition, on above-mentioned folder cutter stone 184, be also provided with the vernier knob 186 for adjustable clamp cutter stone 184 internal clearances, this gap is the path of passing for cutter band 200, by regulating this gap, can make cutter band 200 reduce to greatest extent to wave, and reduce wear. For example, in the time that the speed of cutter band 200 is higher, can suitably increase this gap, otherwise, this gap can suitably be reduced, effectively to protect cutter band 200.

In sum, the utility model adopts three fixing break bars, two mobile break bars transmit cutter band, than four cutter wheel devices that break bar moves in prior art simultaneously, cutter band is more stable in cutting process, is difficult for waving, thereby has reduced the wearing and tearing of cutter band, avoid cutter band surprisingly to fracture, thereby improved the service life of cutter band. In addition, mobile break bar is arranged at and is claimed on moving plate, and claiming that on moving plate, blade insert is turned round in setting, with change cutter band blade towards, thereby can cut the sponge of various density and various shapes, only need a cutting machine just can realize different cutting demands, greatly facilitate consumer, also reduced consumer's use cost.

The foregoing is only preferred embodiment of the present utility model; not thereby limit its scope of the claims; every equivalent structure transformation that utilizes the utility model description and accompanying drawing content to do; directly or indirectly be used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
