Background technology
At present; In the prior art; The relative rest point place that double twisting device is twisted with the fingers thigh in the second time is that the outlet only relies on one " Octoid gear " forming between traction wheel and guide wheel to turn round; This do not having under other any safeguard measure situation, and when in a single day admission machine or steel cord broke down, traction wheel was bound under inertia, proceed rotation; The steel cord on " yet Octoid gear " the admission machine failover stop or can becoming during fracture of wire very loose, twist with the fingers a burst effect second time that has lost relative rest point like this.The situation that causes whole dish steel cord to be scrapped because of this situation in process of production is innumerable; Obviously; Not only wasted cost in the prior art greatly; And " Octoid gear " and the loose meeting of steel cord of twisting with the fingers in strand main frame increase the manipulation strength of coiling again greatly, thereby increased workman's burden.
The utility model content
The purpose of the utility model is exactly the defective that exists to prior art; Provide a kind of simple in structure; Easy to use, it is unaffected to occur at admission machine can both guaranteeing under the situation of any fault that the steel cord is twisted with the fingers burst parameter, prevents that the steel cord is loose; Thereby the minimizing percent defective, the double twisting device that alleviates workman's burden draws cord grip.
Its technical scheme is: double twisting device traction cord grip; Comprise guide wheel and traction wheel; Steel cord coiling between said traction wheel and guide wheel forms one " 8 character wheel ", and a side of said traction wheel is provided with bearing, and said bearing is provided with rotating shaft; Said rotating shaft is provided with the pressing wheel device that rotates around it and be used to compress the steel cord, and said pressing wheel device is meshed with said traction wheel.
Said pressing wheel device comprises the lever that is rotationally connected with rotating shaft; The extension spring that the pinch roller that is arranged on lever end and is meshed with traction wheel and two ends are fixedly connected with lever with said bearing respectively, said bearing is provided with and is used for the caging bolt that said pinch roller is spacing.
Said traction wheel is provided with the groove with vertebra limit, and said pinch roller outer surface is provided with and the identical fin of said groove tapering.
Said lever is provided with first bolt away from an end of pinch roller, and said bearing is provided with second bolt, and the two ends of said extension spring are separately positioned on first bolt and second bolt.
The end that said lever is positioned at pinch roller is provided with the 3rd bolt, and said pinch roller is arranged on an end of the 3rd bolt and is meshed with traction wheel, and the other end of said the 3rd bolt is provided with handle.
The both sides that are positioned at said pinch roller on said the 3rd bolt are respectively equipped with elastic device.
After having adopted technique scheme, the beneficial effect that the utility model is obtained is: simple in structure, easy to use; It is unaffected to occur at admission machine can both guaranteeing under the situation of any fault that the steel cord is twisted with the fingers burst parameter; Prevent that the steel cord is loose, thereby reduce percent defective, alleviated workman's burden.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the structure principle chart of the utility model embodiment.
The specific embodiment
As depicted in figs. 1 and 2; Double twisting device traction cord grip comprises guide wheel 1 and traction wheel 2, forms one " 8 character wheel " in steel cord 14 coilings of 1 on said traction wheel 2 and guide wheel; One side of said traction wheel 2 is provided with bearing 3; Said bearing 3 is provided with rotating shaft 4, and said rotating shaft 4 is provided with the pressing wheel device that rotates around it and be used to compress steel cord 14, and said pressing wheel device is meshed with said traction wheel 2.
Said pressing wheel device comprises the lever 5 that is rotationally connected with rotating shaft 4; The extension spring 7 that the pinch roller 6 that is arranged on lever 5 ends and is meshed with traction wheel 2 and two ends are fixedly connected with lever 5 with said bearing 3 respectively, said bearing 3 are provided with and are used for the caging bolt 8 that said pinch roller 6 is spacing.
Said traction wheel 2 is provided with the groove 21 with vertebra limit, and said pinch roller 6 outer surfaces are provided with and the identical fin 61 of said groove 21 taperings.
Said lever 5 is provided with first bolt 9 away from an end of pinch roller 6, and said bearing 3 is provided with second bolt 10, and the two ends of said extension spring 7 are separately positioned on first bolt 9 and second bolt 10.
The end that said lever 5 is positioned at pinch roller 6 is provided with the 3rd bolt 11, and said pinch roller 6 is arranged on an end of the 3rd bolt 11 and is meshed with traction wheel 2, and the other end of said the 3rd bolt 11 is provided with handle 12.
The both sides that are positioned at said pinch roller 6 on said the 3rd bolt 11 are respectively equipped with elastic device 13.Elastic device 13 can be arranged on the spring of pinch roller 6 both sides; Can guarantee that through this structure pinch roller 6 is all with resilience on both direction; Make pinch roller 6 can go here and there in the axial direction; Eliminated can not be relative because of processing or the alignment error awl limit that causes pinch roller 6 to be meshed with traction wheel 2 drawback, guarantee that fin 61 and groove 21 can compress the steel cord very easily.In the inside of pinch roller 6 bearing is housed during use, can guarantees the high speed rotation of pinch roller 6.
The utilization principle of moments is arranged on two limit directions with lever 5 cleverly in the utility model; When the operative employee winds the line before machine run; Only need hold handle 12 firmly rotates downwards; Lever 5 just can move downward around rotating shaft 4 under the pulling force moment loading of extension spring 7, until arriving at caging bolt 8. Pinch roller 6 and 2 of traction wheels just can form a bigger space and be convenient to manually-operated this moment.When threading accomplish the back promptly " 8 character wheel " accomplish, only need handle 12 is firmly upwards rotated, lever 5 equally in extension spring 7 effects down around rotating shaft 4 rotation that makes progress, until the fin 61 of pinch roller 6 be meshed with the groove 21 of traction wheel 2 tightly push down steel cord 14 till.
The utility model pinch roller 6 and relative extruding of 2 pairs of steel cords 14 of traction wheel when machine run guarantee that steel cord 14 can not jump out traction wheel 2 awl limits.The most important thing is that when admission machine breaks down no matter there is much inertia in main frame, pinch roller 6 all can guarantee the tension force of Octoid gear, just guaranteed to greatest extent that also traction wheel 6 as second effect of twisting with the fingers the system rest point of double twisting device, has significantly reduced percent defective.In addition, when this device guarantees that take-up has fault " 8 character wheels can normal presence ", significantly reduce the amount of labour that winds the line again because of sleave, alleviated operator's burden.
The utility model is simple in structure, and is easy to use, and it is unaffected to occur at admission machine can both guaranteeing under the situation of any fault that the steel cord is twisted with the fingers burst parameter, prevents that the steel cord is loose, thereby reduces percent defective, has alleviated workman's burden.
