For topic so that deburring quality is unstable, the overlap cut off is uneven, it is therefore necessary to which it is improved further.
Utility model content
The purpose of this utility model is to overcome prior art there are the shortcomings that, a kind of simple in structure, user is provided
Just, there can be a kind of blow-molded article overlap dressing mechanism that removal is modified to blow-molded article outer profile overlap.
The utility model aim is realized with the following methods：A kind of blow-molded article overlap dressing mechanism, it is characterised in that：
It includes positioning seat, and plastic products are fixed in positioning seat, further includes three axis servo-drive platforms, is installed on three axis servo-drive platforms
The rack for having cylinder and being driven by it is provided with the gear engaged, the central shaft of gear and three axis servo-drives on rack
Platform and link block connection, rack connect and are driven by it with cylinder, and being drivingly connected block by gear when rack moves swings, described
Link block one end connect with gear, the other end is connect with knife bar, and the top of knife bar is equipped with blade, and blade drives in three axis servos
It is moved under the driving of dynamic platform and rack-and-pinion along the outer profile of plastic products, the overlap on cutting plastic product outer profile.
The link block is in waist type shape, and the central shaft of one end and gear is fixed, and the other end offers guide groove, knife bar
Swingable formula is mounted in the guide groove.
Torsional spring is installed, a support feet of torsional spring is located in guide groove, and another support feet is mounted in the guide groove
In knife bar, torsional spring generates thrust trigger shaft and is swung always to the low direction of the slot of guide groove.
The knife bar top is provided with cutter groove, and blade is removably mounted in the cutter groove.
The beneficial effects of the utility model are：1st, simple in structure, production cost is low, improves the market competitiveness.2nd, using more
Axis servo-drive platform trigger shaft moves so that blade can be moved along the outer profile of blow-molded article, realize that automatic sharpening removes
Deflashing purpose.3rd, it for different angle, can be turned an angle by cylinder trigger shaft so that blade reaches best and scrapes
Top rake degree.4th, knife bar elastic hinge joint is mounted on link block so that blade elasticity is pressed on product surface, so as to ensure cutting force
Stabilization.
Description of the drawings
Fig. 1,2 are the utility model general assembly design sketch.
Fig. 3 is that knife bar assembles using renderings with link block in the utility model.
Fig. 4 is knife bar and link block assembling structure sectional view in the utility model.
Specific embodiment
Make specific further instruction to the utility model below in conjunction with the accompanying drawings.A kind of blow-molded article overlap dressing mechanism,
It is characterized in that：It includes positioning seat, and plastic products 1 are fixed in positioning seat, further includes three axis servo-drive platforms, three axis servos
Cylinder 2 and the rack being driven by it 3 are installed on driving platform, the gear 4 engaged, the center of gear 4 are provided on rack 3
Axis 5 is connect with three axis servo-drive platforms and link block 6, and rack 3 connect and is driven by it with cylinder 2, and rack 3 passes through tooth when moving
4 drive connection block 6 of wheel is swung, and described 6 one end of link block is connect with gear 4, and the other end is connect with knife bar 7, the top of knife bar 7
Blade 8 is installed, blade 8 moves under the driving of three axis servo-drive platforms and rack-and-pinion along the outer profile of plastic products 1,
Overlap on 1 outer profile of cutting plastic product.
The link block 6 is in waist type shape, and one end and the central shaft 5 of gear 4 are fixed, and the other end offers guide groove
61,7 swingable formula of knife bar is mounted in the guide groove 61.
Torsional spring 62 is installed, a support feet of torsional spring 62 is located in guide groove 61, another support in the guide groove 61
Foot is mounted in knife bar 7, and torsional spring 62 generates thrust trigger shaft 7 and swung always to the low direction of the slot of guide groove 61.
7 top of knife bar is provided with cutter groove 71, and blade 8 is removably mounted in the cutter groove 71.
Operation principle：Plastic products in this case are fixed on positioning seat（It is not shown in figure）Interior, cylinder and rack are fixed
Mounted on three axis servo-drive platforms（It is not shown in figure）On.Three axis servo-drive platforms are under the action of control system, trigger shaft
It is moved along the outer profile of plastic products.The blade on knife bar top made carries out scraping along product outer profile, will be on product
Overlap removes.
As shown in Figure 1, 2, there is endoporus for some plastic products（Product handle position in figure）, when needing scraping endoporus
On overlap when, need to convert the angle of blade, adapt it to the contour direction of endoporus.At this point, 2 drive rack 3 of cylinder carries out
Stretching motion, so as to which the gear engaged 4 be driven to rotate, gear 4 is drivingly connected block band moving knife in rotation, by central shaft
Piece deflects so that the cutting angle of blade adapts to scraping track.
Further：In order to enable blade uniform stressed on plastic products and prevent blade from scratching product, knife bar in this case
7 swingable formulas are mounted in the guide groove 61.Torsional spring 62, a support feet of torsional spring 62 are installed in the guide groove 61
In guide groove 61, another support feet is mounted in knife bar 7, and torsional spring 62 generates thrust trigger shaft 7 always to guide groove 61
The low direction of slot swing.Therefore the elastic force that torsional spring generates forces blade uniform stressed in plastic products, ensures the steady of blade scraping
It is qualitative.
Compared with traditional technology, unique blade driving structure in this case may be such that blade can be followed outside product automatically
Contour motion, the scraping of efficient stable are located at the overlap on product, so as to avoid in traditional technology using present in manual cutting
Working efficiency it is low, the drawbacks such as quality is unstable.
The basic principle of the utility model and main feature and the advantages of the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
Only illustrate the principle of the utility model, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
Various changes and modifications are had, these various changes and improvements fall within the scope of the claimed invention.
