Detailed Description
The following detailed description of the present invention is given for the purpose of better understanding technical solutions of the present invention by those skilled in the art, and the present description is only exemplary and explanatory and should not be construed as limiting the scope of the present invention in any way.
As shown in fig. 1 and 2, the specific structure of the present invention is: the utility model provides a bridge of nose cuts off structure in gauze mask built-in, includes that the cutter axle 1 of mutually supporting supports and rolls, and the both ends of cutter axle 1 are provided with the step, cutter axle 1 cooperate and have a drive unit, cutter axle 1 on set up the blade holder mouth that two phase differences are 180 degrees, blade holder in install cutter holder 2, cutter holder 2 on install cutter 3, and the most advanced height that surpasss cutter axle 1 of cutter 3 is greater than the height of step, cutter axle 1 the outside parcel in position of installing cutter 3 have a bed hedgehopping sponge 4, the thickness of bed hedgehopping sponge 4 is greater than the height that cutter 3 surpassed cutter axle 1, and bed hedgehopping sponge 4 has seted up the edge of a knife 5 with cutter 3 complex position.
When the mask slicing structure is used specifically, the structure is combined with the mask slicing structure, the length of a nose bridge strip is determined by the diameter of a cutter shaft and a step, under general conditions, the thickness of the step is 2mm, the thickness of sponge of a backing cutter is 3mm, the height of the cutter exceeding the step is 0.5mm, the nose bridge strip is actually driven by the rotation of the compressed sponge of the backing cutter, in order to ensure that the slicing structure is matched with the nose bridge strip, the rotating speed of the cutter shaft is two times of the rotating speed of a hob of the slicing structure, and the material of the rolling and the cutter is consistent; the specific operation is as follows, the end of the nose bridge strip penetrates between the support roller and the sponge backing knife, then the cutter shaft 1 descends, the cutter 3 can cut off the nose bridge strip, the nose bridge strip is driven by the sponge backing knife to carry out the transportation in the same direction as the cloth, and is cut off by the cutter 3 after the cutter shaft rotates for a half circle, the cut nose bridge strip enters between the two layers of cloth, and is transported together with the cloth, so that the profiling and slicing are realized; this cut-off structure can cooperate the transport of cloth piece to realize bridge of the nose strip and cloth piece syntropy feeding, can drive bridge of the nose strip and remove when simultaneously cutting off bridge of the nose strip, compares current cam propelling movement structure, and the relative movement error range between bridge of the nose strip and the cloth submits greatly, and then can carry out high-speed piece of beating, and the per minute reaches more than 80, improves the whole efficiency of beating the piece.
As shown in fig. 2, the cutting knife 3 is a blade with one side inclined, the plane direction is in the diameter direction of the cutting knife shaft 1, and the phase difference between the two cutting knives 3 is 180 degrees.
The cutter blade with one inclined side is adopted, the phase difference of the cutter 3 is ensured to be 180 degrees, the cutter can be ensured to be positioned in the diameter direction of the cutter shaft, and the cutting precision can be improved.
As shown in fig. 1-3, the wrapping method of the padded sponge comprises the following steps: firstly, wrapping a cutter shaft with sponge strips, and then cutting the sponge strips to ensure that the cut sponge strips can just wrap the cutter shaft for one circle; secondly, cutting off the sponge strips after the first cutting from the middle to obtain sponge blocks A and sponge blocks B; thirdly, overlapping the sponge blocks A and B, and then respectively forming a first cut 501 and a second cut 502 on the two side edges; and fourthly, bonding the sponge blocks A and B on a cutter shaft, wherein one cutter edge consists of a first cut of the sponge block A and a second cut of the sponge block B, and the other cutter edge consists of a first cut of the sponge block B and a second cut of the sponge block A.
Adopt the parcel method of above-mentioned bed hedgehopping sponge, can ensure that the size of two incisions is identical completely, and the phase difference also is 180 degrees, so can ensure that the range that its bridge of the nose strip that drives removes is identical completely, ensure the length of bridge of the nose strip unanimous, because the cutter is the unilateral slope, and the plane direction is in the diameter direction of cutter axle 1, the edge of a knife on the cutter seat must not be in the center so, therefore the condition that the artificial dress is turned over appears in the cutter seat easily, through this method, can play the condition of detecting whether the cutter seat adorns to turn over.
As shown in fig. 3, the end face of the sponge block is flush with the plane of the cutter, the inclined side of the cutter is a first notch, and the width of the first notch is the sum of the thickness of the cutter and the width of the second notch.
The end face of the sponge block is flush with the plane of the cutter, the width of the first cut and the width of the second cut are limited, normally, the cutter 3 is necessarily in the center of the cut, if the cutter is not in the center, the condition that the cutter is reversely installed is considered, and the effect of further detecting and feeding back is achieved for the installation of the cutter.
As shown in fig. 3, the contact part of the sponge block and the cutter shaft 1 is bonded by double faced adhesive tape, and the part matched with the cutter seat 2 is not bonded; the contact parts of the two sponge blocks are bonded by a transparent adhesive tape 6, and the bonded parts are positioned at the outer side of the knife edge 4.
Adopt the double faced adhesive tape to bond the sponge piece on cutter shaft 1, and ensure that cutter seat 2 does not have the bonding relation with the sponge piece, realize the bonding of two sponge pieces through scotch tape 6, so can enough realize the effect that the sabot sponge drives the removal of nose bridge strip, can make things convenient for the dismantlement of cutter seat 2 simultaneously, and then made things convenient for the change of cutter 4.
