Description
Technical field
The utility model relates to twisting frame technical field, refers to particularly a kind of monofilament unwrapping wire cradle absorbing buffer unit.
Background technology
In twisting frame equipment, monofilament unwrapping wire cradle is main working parts, and it is connected as a single entity by hanger and being rigidly connected of spinning roller axle.During work, by spinning roller axle, rotarily drive Loosen up wire wheel unwrapping wire in monofilament unwrapping wire cradle.In this process, spinning roller axle is to reduce by dynamic balancing the vibration bringing due to self amount of unbalance, but no matter dynamic balance accuracy accomplishes how many, this amount of unbalance exists all the time, the vibration bringing thus also accompanies all the time, particularly, when spinning roller axle High Rotation Speed, the vibration that amount of unbalance now brings is larger.Simultaneously, the also ceaselessly vibration along with the variation of laying tension due to Loosen up wire wheel self in monofilament unwrapping wire cradle, the stack of these two kinds of vibrations has increased the vibration of the rigid connection body of hanger and spinning roller axle, thereby have influence on the stable of the rotation of spinning roller axle and Loosen up wire wheel laying tension, cause the possibility of each parts plastic deformation of monofilament unwrapping wire cradle and unstable product quality to increase.
Summary of the invention
The purpose of this utility model is exactly that a kind of reliable and stable monofilament unwrapping wire cradle absorbing buffer unit of cord product that can cushion absorbing, production will be provided.
For achieving the above object, the monofilament unwrapping wire cradle absorbing buffer unit that the utility model is designed, be included in the cradle soleplate that major axis two ends are arranged with hanger, described cradle soleplate end face center is provided with coaxial unwrapping wire cradle I-shaped wheel shaft and the Loosen up wire wheel arranging from inside to outside, the end face of each hanger both sides is fixed with respectively opening F type hanger Connection Block inwardly, in the middle of the structure that each hanger and two corresponding hanger Connection Blocks surround, be provided with by the fixing bearing block of frame, in the endoporus of described bearing block, be provided with bearing and spinning roller axle that ecto-entad sets gradually, described bearing block top is a plane, this bearing block plane is provided with the flat spring that middle part is fixedly linked with it, described flat spring two ends are connected with hanger Connection Block end face respectively.The vibration that spinning roller axle and Loosen up wire wheel bring that is arranged so that of flat spring slows down greatly.
As preferred version, each hanger crown center is provided with recess, the bearing block bottom corresponding with this hanger stretched in this recess, described bearing block bottom outer rim is provided with one section of boss arranging around bearing block bottom, between the outward flange of described boss and hanger recess inward flange, be provided with gap h1, described boss two ends are respectively the top planes lower than hanger end face, two the hanger Connection Block horizontal base rod end surface corresponding with bearing block inwardly protrude from respectively the inward flange of recess, between each hanger Connection Block horizontal bottom bar bottom surface and the boss top planes corresponding with it, be provided with space h2.Arranging of h1He space, gap h2 guaranteed that strain only occurs flat spring within the scope of this, reaches the object that slows down spinning roller axle and Loosen up wire wheel vibration.
Further, described gap h1=3.5～3.9mm, described space h2=1.3～1.6mm.
Enter again a ground, described gap h1=3.7mm, described space h2=1.5mm.The numerical value of h1He space, gap h2 is that the coefficient of elasticity by computing board spring obtains.
Also further, described bearing block is annular, and described boss is semicircle annular, the recess semicircular in shape of each hanger.
Further, described bearing block end face is provided with the alignment pin through flat spring middle part.Alignment pin is set and is convenient to installing plate spring.
Further, each bearing block top is provided with two flat springs that stack up and down.The setting of upper and lower two flat springs makes the ability of the utility model absorbing buffering stronger.
Further, described hanger is connected with hanger Connection Block by cradle soleplate connecting bolt, and described flat spring is connected with hanger Connection Block with bearing block by a plurality of flat spring connecting bolts respectively.Connected mode of the present utility model is with bolts is that the efficiency of safeguarding compared to being welded to connect is higher for the ease of safeguarding, cost is lower.
Further, described flat spring connecting bolt is connected with flat spring by briquetting.Briquetting can increase the contact-making surface of flat spring connecting bolt and flat spring, reduces pressure, is convenient to fix the probability that reduces to get loose.
Operation principle of the present utility model is such: flexible member---flat spring is arranged on bearing block and hanger Connection Block in the utility model employing, when spinning roller axle rotates, the vibration that the vibration being brought by spinning roller axle self amount of unbalance and unwrapping wire cradle I-shaped wheel shaft laying tension bring is by flat spring snubber.Flat spring is designed to have certain rigidity value, between hanger and bearing block boss and between hanger Connection Block and bearing block boss, also designing respectively h1He space, gap h2, thereby guarantee that strain only occurs flat spring within the scope of this, there is not plastic deformation, shock attenuation result is better, concrete reason is as follows: spinning roller axle rotation during whole device work, drives the unwrapping wire cradle I-shaped wheel shaft on cradle soleplate, and then drive Loosen up wire wheel rotation unwrapping wire; When spinning roller axially above vibrates, flat spring two ends are fixing point, on mid portion, move, and above the amount of moving is the boss top planes at boss two ends and the space h2 of the horizontal bottom bar of hanger Connection Block bottom surface; When spinning roller axially vibrates down, flat spring two ends are fixing point, and mid portion moves down, the gap h1 between the outward flange that the amount of moving down is boss and hanger recess inward flange; And unwrapping wire cradle I-shaped wheel shaft laying tension on cradle soleplate changes and causes when cradle soleplate upwards vibrates, in the middle of flat spring, be fixing point, on two ends, move the gap h1 between the outward flange that above amount of moving is boss and hanger recess inward flange; When cradle soleplate vibrates downwards, in the middle of flat spring, be fixing point, two ends move down, and the amount of moving down is the boss top planes at boss two ends and the space h2 of the horizontal bottom bar of hanger Connection Block bottom surface.No matter up-down vibration or unwrapping wire cradle I-shaped wheel shaft laying tension while being the rotation of spinning roller axle change the up-down vibration causing, all by the synergy of flat spring and h1He space, gap h2, eliminated the mutual transmission of vibration values and influenced each other, reduced the stack of the whirling vibration of spinning roller axle and the vibration of unwrapping wire cradle I-shaped wheel shaft unwrapping wire, greatly eliminate the whirling vibration of spinning roller axle and the impact of unwrapping wire cradle I-shaped wheel shaft unwrapping wire vibration on setting-out work, guaranteed the stable of cord product quality.
The utility model has the advantage of: simple in structure, buffering absorbing, reliable and stable, reduced the stack of the whirling vibration of spinning roller axle and the vibration of unwrapping wire cradle I-shaped wheel shaft unwrapping wire, become the strain that in prior art, each parts plastic deformation of monofilament unwrapping wire cradle is flat spring, guaranteed the stable of cord product quality.
