Abstract
The utility model provides a grasping slip difference torsion ring of a small-specification paper core, which is used matching with a rolling core. The torsion ring comprises a cylinder body and a bearing seat which is arranged at one end of the cylinder body. The torsion ring is characterized in that the cylinder body is sunken from the outer wall in a radial manner to form a plurality of containing grooves, and convex blocks which are respectively arranged in the containing grooves are connected with the containing grooves by elastic elements. The containing grooves are arranged on the outerwall of the cylinder body, and the convex blocks which are connected with the elastic elements are arranged in the containing grooves, so that the grasping slip difference torsion ring of the small-specification paper core can bear the rolling core with small width.
Description
Technical field
The present invention is about a kind of torsion ring, refers to a kind ofly in the rewinding process especially, firmly grasps slippage torsion ring with the small dimension refill that the volume core is used.
Background technology
The rewinding process generally comprises operations such as charging, coiled strip, discharging and sticking limit, and wherein the coiled strip operation is mainly finished by rewinding mechanism and pressure mechanism, and rewinding mechanism comprises a pair of rewind roll, in order to rotate the volume core.In the winding process, because
The variable thickness of the material of reeling is identical all the time surely, therefore can cause the tension force of Ge Do coiled material not exclusively equal, and then causes coiled material became uneven on each volume core.
The prior art employing is provided with unidirectional torsion ring and solves this problem between volume core and rewind roll.This unidirectional torsion ring is the Baltimore groove structure, and open the Baltimore groove upper end, is provided with flap torsion body in the groove, and this flap torsion body is connected with the Baltimore groove inwall.The Baltimore groove outer wall slips with the volume core.When thicker part contacted with pressure mechanism on the volume core, the pressure that is subjected to was bigger, produces slide relative between rewind roll and the unidirectional torsion ring, made coiled material obtain suitable elasticity.
But the unidirectional torsion ring of this kind has bigger width, therefore can not be applied to the less volume core of width.
Summary of the invention
The utility model provides a kind of width can accomplish that very little small dimension refill firmly grasps slippage torsion ring, with in the rewinding process, is applicable to the volume core that width is less.
The utility model adopts following technical scheme:
A kind of small dimension refill is firmly grasped slippage torsion ring, in order to be used with the volume core, comprise cylindrical shell and bearing, this bearing is arranged at cylindrical shell one end, described cylindrical shell is radially subside from outer wall and is formed several accepting grooves, be provided with projection in each accepting groove, this projection is connected with accepting groove by elastic element.
Described elastic element can be spring.Described projection is formed by base and the column that is formed on this base, and the base of described projection is captiveed joint with elastic element.
Described accepting groove is connected and composed by neck groove and abdomen groove, and section is convex, and the neck groove is in order to the column of ccontaining described projection, and the abdomen groove is in order to the base of ccontaining described projection, and the junction of neck groove and abdomen groove forms convex shoulder, and this convex shoulder is in order to the described base of block.
The utility model is set to convex by accepting groove, utilizes the base of the convex shoulder backstop projection of accepting groove, can make the projection motion steadily.
The utility model is provided with and elastic element bonded assembly projection in accepting groove then by accepting groove is set on cylinder body outer wall, can make the width of torsion ring accomplish very little.
Description of drawings
Fig. 1 shows the structural representation of firmly grasping slippage torsion ring according to small dimension refill of the present utility model.
Fig. 2 shows the embodiment cross-sectional schematic of firmly grasping slippage torsion ring according to small dimension refill of the present utility model.
Main element nomenclature among the figure
10 cylindrical shells, 11 cylinder body outer walls
12 cylinder inboard walls, 13 accepting grooves
131 neck grooves, 132 abdomen grooves
14 projections, 141 bases
142 columns, 15 elastic elements
20 bearings, 30 volume cores
| 40 rewind roll |
The specific embodiment
See also Fig. 1 and Fig. 2, the utility model comprises cylindrical shell 10 and bearing 20, and this bearing 20 is arranged at cylindrical shell one end.Cylindrical shell 10 is cylindric, and cylindrical shell has outer wall 11 and inwall 12.Cylindrical shell 10 is radially subside from outer wall 11 and is formed several accepting grooves 13, is provided with projection 14 in each accepting groove 13, and this projection 14 is connected with accepting groove 13 bottoms by elastic element 15.In this embodiment, elastic element 15 is a spring, also can use other elastic constructions.Projection 14 is formed by base 141 and the column 142 that is formed on this base 141, and base 141 is captiveed joint with elastic element 15.Described accepting groove 13 is connected and composed by neck groove 131 and abdomen groove 132, section is convex, neck groove 131 is in order to the column 142 of ccontaining described projection 14, abdomen groove 132 is in order to the base 141 of ccontaining described projection 14, the junction of neck groove 131 and abdomen groove 132 forms convex shoulder, this convex shoulder moves base 141 and elastic element 15 in order to the described base 141 of block in abdomen groove 132.
During work, the small dimension refill is firmly grasped slippage torsion ring set place volume core 30, this moment, the small dimension refill was firmly grasped the outer wall 11 flexible connection volume cores of the cylindrical shell 10 of slippage torsion ring, and inwall 12 flexibly connects the rewind roll 40 of rewinding mechanisms, projection 14 apical graftings volume core 30 inwalls.Rewinding machine utilizes the small dimension refill to firmly grasp 30 rotations of the moving volume of slippage torsion endless belt core by rewind roll 4, and coiled material is to roll up on the core around the home.When volume core 30 when coiling process is subjected to coiled material and opens (drawing) power more greatly, projection 14 will press volume core 3, make the small dimension refill firmly grasp slippage torsion ring and can not skid with volume core 30, and rewind roll 40 is firmly grasped slippage torsion ring generation relative motion with the small dimension refill, coiled material obtains suitable elasticity.
The utility model is set to convex by accepting groove, utilizes the base of the convex shoulder backstop projection of accepting groove, makes the projection motion steadily.Accepting groove directly forms from cylinder body outer wall, and projection and elastic element directly are arranged in this accepting groove, and the width that can make the small dimension refill firmly grasp slippage torsion ring is accomplished very little.
The above only is preferred embodiment of the present utility model, and those skilled in the art under the situation that does not break away from technology category of the present utility model, still can do multiple variation to it, and these variations all should be considered as scope disclosed in the utility model.
