A kind of up cut resin teeth zipper special cutter seat
Technical field
The present invention relates to slide fastener process units technical field, mainly refer to a kind of up cut resin teeth zipper special cutter seat.
Background technology
During resin teeth zipper row miaow is produced, need carry out cutting and separating to miaow tooth and the clout of slide fastener through the Cutter apron device, thereby obtain satisfactory miaow tooth confession subsequent production.
Chinese patent CN200620125405.9 discloses " slide fastener production is with resin row miaow machine Cutter apron device "; Comprise rectangle cutting knife pedestal, cutting knife; Two parallel cutting knife pedestal upper cutter grooves that place of plane lamina cutting knife; The cutting tip of plane lamina cutting knife stretches out at Cutter apron external, and the plane lamina cutting knife in the pedestal is embedded by L shaped cushion block and is fixed in (with reference to accompanying drawing 1) in the cutting knife groove.The advantage of this structure is to pass through the position, the left and right sides of two blades of thickness adjusted of increase and decrease pad, can satisfy the demand of different shrinkage factor slide fasteners.Shortcoming one is that adjusting is cumbersome, can leave tiny burr or slight miaow tooth head cut wound on the slide fastener miaow tooth after the separation; Shortcoming two is that blade exchange is more frequent, and the blade angle of blade is uncontrollable.
Summary of the invention
The present invention is just in order to overcome above-mentioned deficiency; A kind of up cut resin teeth zipper special cutter seat is provided, overcome the problem that leaves burr or miaow tooth cut wound behind cutting miaow tooth and the clout, easy and simple to handle with this special cutter seat production slide fastener; The aesthetics of slide fastener miaow tooth is better, more stable quality.
Concrete enforcement like this: a kind of up cut resin teeth zipper special cutter seat comprises the cutting knife pedestal, cutting knife; The centre that it is characterized in that the cutting knife base plate is equipped with protruding core, and the core both sides connect the cutting knife pedestal respectively, and cutting knife is installed in the detent of cutting knife pedestal; In the groove of the cutting edge insert type wicking surface of cutting knife; The front end of cutting knife pedestal is equipped with wheel stand, on the end face of wheel stand guide wheel is installed, and leaves guide chain groove between described guide wheel and cutting knife base plate.
For the miaow tooth surface that guarantees to cut is bright and clean, the present invention selects L shaped cutting knife, and the inboard angle of the point of a knife of L shaped cutting knife is identical with the die joint angle of miaow tooth end face.
Be provided with set screw between the afterbody of cutting knife and cutting knife pedestal,, can let the cutting knife edge of a knife be controlled at accurately on the cutting position, make that blade is inboard tightly fits with the miaow tooth through set screw.
The top of cutting knife pedestal and cutting knife is equipped with the adjustment cover plate, and described adjustment cover plate is fixed on the cutting knife pedestal, is provided with the cutting knife holding screw in addition on the adjustment cover plate.After cutting knife is adjusted to accurate position, can limit seesawing up and down of cutting knife through the cutting knife holding screw on the adjustment cover plate.

The specific embodiment
A kind of up cut resin teeth zipper special cutter seat, the centre of cutting knife base plate 5 are equipped with protruding core 6, and core 6 both sides connect cutting knife pedestal 4 respectively; L shaped cutting knife 3 is installed in the detent of cutting knife pedestal 4; The inboard angle of the point of a knife of L shaped cutting knife is identical with the die joint angle of miaow tooth end face, and the cutting edge of cutting knife 3 inserts in the groove on core 6 surfaces, and the front end of cutting knife pedestal 4 is equipped with wheel stand 2; Guide wheel 7 is installed on the end face of wheel stand 2, and 5 of guide wheel 7 and cutting knife base plates leave guide chain groove.
4 of the afterbody of cutting knife 3 and cutting knife pedestals are provided with set screw 12, and the top of cutting knife pedestal 4 and cutting knife 3 is equipped with adjustment cover plate 1, and adjustment cover plate 1 is fixed on the cutting knife pedestal 4, are provided with cutting knife holding screw 13 in addition on the adjustment cover plate 1.
During work, with reference to accompanying drawing 2, resin row miaow prow carries out injection mo(u)lding to zipper cloth belt 11 earlier, and the miaow tooth 9 after the injection moulding is connected by the sprue gate 10 of material bar 8.Have the slide fastener of expecting bar 8 and under the drive of row's miaow machine drive, begin to get into Cutter apron; Bottom surface and core 6 at the guide effect blanking bar 8 of guide wheel 7 are tightly fitted; In motion process, miaow tooth, sprue gate are separated by the cutting edge of cutting knife, and miaow tooth 9 moves along guide chain groove simultaneously; Under the continuous effect of pulling force, miaow tooth 9 has been realized separating fully with sprue gate 10.
