Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Considering that the working efficiency of the current drawing-in machine is low, in order to improve the whole working efficiency of the drawing-in machine, the divided yarns can be transferred to the next station at the first time, and in the process of sending the yarns to the arrow hook pre-hooking line and waiting for the arrow hook to hook the line away, the yarn dividing mechanism can perform the next yarn dividing action, so that the yarn dividing mechanism and the yarn hooking mechanism run in parallel, and meanwhile, enough time is reserved for the yarn dividing mechanism to divide the yarns for multiple times.
Specifically, referring to fig. 1 to 5, the yarn transferring device of the drawing-in machine provided by the present invention includes a first grade yarn dividing mechanism 10, an upper and lower yarn dividing mechanism 20, a second grade yarn dividing mechanism 30, an upper yarn dividing mechanism 40, and a guide rail yarn sucking device 50, which are sequentially arranged from bottom to top.
After the yarn is separated from the yarn curtain by the first grade yarn separating mechanism 10, the upper and lower marking mechanisms 20 move to dial the yarn to the yarn hooking position of the second grade yarn separating mechanism 30, the second grade yarn separating mechanism 30 transfers the yarn to the working position of the upper marking mechanism 40, so that the yarn is separated from the running track of the first grade yarn separating mechanism 10, and the guide rail yarn sucking device 50 fixes the yarn at the arrow belt yarn hooking position. Therefore, even if the yarn branching mechanism branches yarns for many times, the yarns cannot be separated from the yarn hooking positions due to vibration or other reasons, and the success rate of arrow belt yarn hooking is ensured.
Further, the up-down scribing mechanism 20 includes a first sliding bar 201 and a second sliding bar 202 which are oppositely arranged, and a transmission gear mechanism 203 for driving the first sliding bar 201 and the second sliding bar 202 to move up and down simultaneously to drive the yarn to be transferred.
The second-level wire dividing mechanism 30 comprises a power mechanism 301, a linkage mechanism 302, and a first wire dividing hook 303 and a second wire dividing hook 304 which are arranged oppositely, the first wire dividing hook 303 and the second wire dividing hook 304 are connected through the linkage mechanism 302, and the power mechanism 301 is used for driving the linkage mechanism 302 to drive the first wire dividing hook 303 and the second wire dividing hook 304 to rotate.
After the first yarn dividing mechanism 10 divides the yarn from the yarn curtain, the first slide bar 201 and the second slide bar 202 are inserted into a gap between the yarn and the yarn curtain and divide the yarn to the first yarn dividing hook 303 and the second yarn dividing hook 304, and the yarn is further divided from the yarn curtain by the rotation of the first yarn dividing hook 303 and the second yarn dividing hook 304, so that the divided yarn is separated from the running track of the first yarn dividing mechanism 10, and the yarn is moved to the upper yarn dividing mechanism 40.
Further, the upper scribing mechanism 40 includes a first scribing hook 401 and a second scribing hook 402 which are oppositely disposed. The first marking hook 401 and the second marking hook 402 are used for bringing the yarn to an arrow belt hook line position, and the yarn is sucked through the guide rail thread suction device 50.
Furthermore, the thread-drawing machine thread-transferring device also comprises a thread-clamping device 60.
Furthermore, the front sections of the first sliding bar 201 and the second sliding bar 202 are provided with bends. The bending of the front sections of the first sliding rod 201 and the second sliding rod 202 can increase the cutting angles of the first sliding rod 201 and the second sliding rod 202, and the branching distance is further increased, so that the stability of the cutting of the first sliding rod 201 and the second sliding rod 202 and the smooth entering of yarns into the station of the secondary branching mechanism 30 are ensured.
The working principle of the yarn transfer device of the drawing-in machine according to the invention is explained in further detail below.
After a yarn is separated from a yarn curtain through the first yarn dividing mechanism 10, the upper and lower line marking mechanisms 20 act, the first sliding rod 201 and the second sliding rod 202 rotate synchronously to dial the yarn to the line hooking position of the second yarn dividing mechanism 30, and the first yarn dividing hook 303 and the second yarn dividing hook 304 in the second yarn dividing mechanism 30 rotate simultaneously through the linkage mechanism 302 to transfer the yarn to the working position of the upper line marking mechanism 40, and simultaneously enable the yarn to be separated from the working track position of the first yarn dividing mechanism. At this time, the first branching mechanism can act to perform branching and judgment operation for the next time. In the upper marking mechanism 40, the first marking hook 401 or the second marking hook 402 moves simultaneously with the thread cutting mechanism, the yarn is brought to the upper arrow belt hook marking position of the device by rotating from bottom to top, the guide thread sucking device 50 on the guide rail at the marking position starts to suck the yarn to prevent the yarn from being separated, and meanwhile, the other marking hook rotates to the pre-marking position to prepare for marking next time. Therefore, the arrow belt and the branching mechanism run simultaneously, and time is reserved for multiple branching of the first branching mechanism. The link mechanism and the synchronous motion mechanism in the up-down scribing mechanism 20 realize that one power drives the first slide bar 201 and the second slide bar 202 to move simultaneously, so that the consistency of the movement is ensured, and the problems of yarn breakage and the like caused by asynchronous up-down movement in two power processes are avoided. Meanwhile, the front sections of the first sliding rod 201 and the second sliding rod 202 are provided with bends, so that the cutting-in angle of the marking bar can be increased, the thread dividing distance is further increased, and the stability of cutting-in of the first sliding rod 201 and the second sliding rod 202 and the smooth entering of yarns into the station of the secondary thread dividing mechanism 30 are ensured.
In summary, the yarn transfer device of the drawing-in machine comprises a first grade of yarn dividing mechanism, an upper and lower yarn dividing mechanism, a second grade of yarn dividing mechanism, an upper yarn dividing mechanism and a guide rail yarn suction device which are sequentially arranged from bottom to top through the technical scheme; after the yarn is separated from the yarn curtain by the first grade yarn separating mechanism, the upper and lower marking mechanisms move to shift the yarn to the yarn hooking position of the second grade yarn separating mechanism, the second grade yarn separating mechanism transfers the yarn to the working position of the upper marking mechanism, the yarn is enabled to be separated from the running track of the first grade yarn separating mechanism, the guide rail yarn sucking device fixes the yarn at the yarn hooking position of the arrow belt, and compared with the prior art, the working efficiency of the drawing-in machine is improved.
