Description

Technical Field

[0001] The invention relates to the technical field of composite yarn twisting, in particular to an aramid composite yarn twisting device that prevents wire breakage. Background Art

[0002] Aramid composite twisted yarn is a yarn made by twisting aramid fiber with other fibers or materials. Multiple aramid fibers or aramid fibers with other fibers are combined together and initially twisted through twisting equipment to make the fibers embrace each other to form a primary twisted yarn with certain strength and stability. Multiple primary twisted yarns are twisted again to further improve the strength and compactness of the yarn. The secondary twisting can make the yarn structure more stable and the surface smoother, thereby improving the wear resistance and fatigue resistance of the yarn.

[0003] In the twisting process, tension control is crucial. If the tension control system fails, such as the tension sensor fails or the tension adjustment device does not work properly, the yarn tension may be too large or too small. When the tension is too large, the tensile force on the fiber exceeds its tolerance limit and the thread will break. When the tension is too small, the yarn becomes loose and is prone to entanglement during the twisting process, which in turn causes the fiber to be torn. For this reason, we have proposed an anti-breakage aramid composite yarn twisting equipment. Summary of the invention

[0004] The purpose of the present invention is to provide an aramid composite yarn twisting device that prevents wire breakage, so as to solve the problem raised in the above background technology that tension control is crucial in the twisting process. If the tension control system fails, such as the tension sensor fails or the tension adjustment device cannot work normally, the yarn tension may be too large or too small. When the tension is too large, the tensile force on the fiber exceeds its tolerance limit and the fiber will break. When the tension is too small, the yarn becomes loose and is prone to entanglement during the twisting process, which in turn causes the fiber to be torn. To achieve the above-mentioned purpose, the present invention provides the following technical scheme: an anti-breaking aramid composite yarn twisting equipment, comprising a workbench, a connecting plate is fixedly connected to the top of the workbench, a tension adjustment component is arranged on the top of the connecting plate, the tension adjustment component comprises a connecting frame, the connecting frame is fixedly connected to the top of the connecting plate, sliding grooves are respectively provided on the inner walls on both sides of the connecting frame, the two sliding grooves are symmetrically distributed on the inner walls on both sides of the connecting frame, a sliding block is movably connected to the inside of the two sliding grooves, two connecting blocks are fixedly connected to the top of the sliding block, the two connecting blocks are symmetrically distributed on the top of the sliding block, a take-up wheel is fixedly connected to the opposite sides of the two connecting blocks, an extension plate is fixedly connected to the top of each connecting block, and a fixed plate is fixedly connected to the opposite sides of the two extension plates The two wheels are connected to each other with a plurality of wheels respectively, and the two wheels are connected to the driving wheel by a plurality of wheels respectively.

[0005] Further preferably, a twisted wire assembly is provided on the top of the transmission frame, and the twisted wire assembly includes two fixed brackets, and the two fixed brackets are respectively fixedly connected to the tops of the two transmission frames.

[0006] Further preferably, the two fixing brackets are symmetrically distributed on the top of the transmission frame, and opposite sides of the two fixing brackets are commonly fixedly connected with a clearance frame.

[0007] Further preferably, a groove is provided on one side of the air avoidance frame, and two transfer frames are movably connected inside the groove, and the two transfer frames are symmetrically distributed inside the groove.

[0008] Further preferably, a placement plate is fixedly connected to one opposite side of the two fixed brackets, a wire inlet is provided inside the placement plate, and a rotating ring is fixedly connected inside the wire inlet.

[0009] Further preferably, the top of the rotating ring is fixedly connected to a limiting frame, the side surface of the rotating ring is movably connected to a transmission belt, the interior of the transmission belt is movably connected to a fixed column, and the rotating ring is transmission-connected to the fixed column via the transmission belt.

[0010] Further preferably, a placement plate is fixedly connected to the top of the connecting frame, and a pay-off wheel is fixedly connected to the top of the placement plate.

[0011] Further preferably, four supporting legs are fixedly connected to the bottom of the workbench, and the four supporting legs are symmetrically distributed on the bottom of the workbench. The cable on the pay-off wheel passes through two transfer frames, and then passes through the limit frames through the two transfer frames to pass through the wire inlet, and is finally wound around the side surface of the take-up wheel. The fixed column is driven to rotate by an external motor, and the fixed column drives the transmission belt to rotate, so that when the yarn passes through the wire inlet, two or more yarns can be twisted, thereby completing the twisting work, which makes the equipment have higher stability and practicality.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In the present invention, when adjusting the tension, when it is necessary to reduce the tension, move the sliding block so that the sliding block drives the take-up wheel to move forward, thereby causing the sliding block to drive the connecting columns on both sides to slide in the curved groove. Since the curved groove is gradually from top to bottom and the transmission frame is not connected to the connecting frame, when the connecting column slides in the curved groove, the fixed bracket on the top of the transmission frame will rise or fall, thereby completing the tension adjustment. When the tension needs to be reduced, it is only necessary to move the slider in the opposite direction.

The sliding block 303 drives the take-up wheel 305 to move forward, so that the sliding block 303 drives the connecting columns 308 on both sides to slide in the curved groove 310. Since the curved groove 310 is gradually from top to bottom and the transmission frame 309 is not connected to the connecting frame 301, when the connecting column 308 slides in the curved groove 310, the fixed bracket 401 on the top of the transmission frame 309 will rise or fall, thereby completing the tension adjustment.

When adjusting the tension, if it is necessary to reduce the tension, move the sliding block 303 so that the sliding block 303 drives the take-up wheel 305 to move forward, so that the sliding block 303 drives the connecting columns 308 on both sides to slide in the curved groove 310. Since the curved groove 310 is gradually from top to bottom and transmits The movable frame 309 is not connected to the connecting frame 301. When the connecting column 308 slides in the curved groove 310, the fixed bracket 401 on the top of the transmission frame 309 will rise or fall, thereby completing the tension adjustment. When the tension needs to be reduced, it is only necessary to move the slider in the opposite direction.
