Description

Vertical twisting and winding device for hair fibers

Technical Field

The utility model belongs to the technical field of chemical fiber production machinery, and in particular relates to a vertical twisting and winding device for hair fibers.

Background Art

In the production process of hair fibers, the fibers need to be twisted to increase their strength, or the fibers need to be pre-twisted due to the demand for new wig products. The false twisting process currently used in the textile industry has some shortcomings for hair fibers, such as the twisting speed is too fast, resulting in the breakage of the hair fibers, excessive tension, etc., which affects the quality of the fibers. The new products currently under development require the treatment of 2-6 fibers with different twists, and the twisting and winding are carried out simultaneously to reduce the length and complexity of the process. The current popular twisting methods in the textile industry either fix one end of the tow to rotate forward or reverse, or fix the middle part to form a false twist. These methods are not very suitable for the current production process requirements of hair fibers.

Utility Model Content

In order to solve the deficiencies in the prior art, the utility model provides a vertical twisting and winding device for hair fibers, which has moderate tension, is not easy to break fibers, and ensures the quality of the twisted fiber bundles.

The upper hanger is provided with a guide sleeve located below the guide wheel. The guide sleeve is transparent from top to bottom and is in the shape of a conical cylinder with a thick bottom and a thin top. The lower end of the guide sleeve is folded outward to form a smooth curved guide opening. All fiber yarns on the bobbin pass upward through the guide sleeve and then bypass the guide wheel and are pulled forward horizontally for output.

Both ends of the central axis of the guide wheel are provided with U-shaped limiters through bolts to prevent the fiber bundle from falling off the wheel after twisting and winding.

The horizontal rotating mechanism includes a variable frequency speed regulating motor, a vertical rotating shaft and a pallet. The upper end and the lower end of the vertical rotating shaft are rotatably connected to the lower bracket through pressure bearings respectively. The pallet is arranged horizontally. The pallet and the vertical rotating shaft have the same center line. The lower surface of the pallet is fixedly connected to the upper end of the vertical rotating shaft. A plurality of first reinforcing ribs are arranged between the lower surface of the pallet and the outer circle of the vertical rotating shaft. The variable frequency speed regulating motor is connected to the vertical rotating shaft through a V-belt transmission mechanism.

Six vertical positioning frames are arranged in a circular array along the center line of the pallet, and each vertical positioning frame includes a vertically arranged fixed shaft, the lower end of the fixed shaft is fixedly connected to the pallet, a plurality of second reinforcing ribs are arranged on the outer circle of the lower end of the fixed shaft and the upper surface of the pallet, and a group of rotating positioning components that roll with the inner circle of the bobbin are arranged on the lower and upper parts of the fixed shaft.

The rotary positioning assembly includes four L-shaped wheel frames arranged along the circumference of the fixed shaft. The ends of the horizontal sections of the L-shaped wheel frames are fixedly connected to the outer circle of the fixed shaft. The vertical sections of the L-shaped wheel frames are interference fitted with rolling bearings. A third reinforcing rib is provided between the L-shaped wheel frame and the outer circle of the fixed shaft.

By adopting the above technical scheme, when the utility model is used, the bobbin wrapped with fiber filaments is first sleeved on the vertical positioning frame, supported on the tray through the lower end, and the inner circle of the bobbin and the rolling bearing of the rotating positioning assembly have a small gap (to ensure the convenience of sleeve and take out the bobbin, and at the same time the bobbin will not have a large shake), all the fiber filaments on the bobbin are pulled upward and pass through the guide sleeve and the U-shaped limiter in turn, and then bypass the wire guide wheel to be pulled horizontally, start the variable frequency speed regulating motor, the variable frequency speed regulating motor drives the vertical rotating shaft to rotate through the V-belt transmission mechanism, and the vertical rotating shaft drives the tray to rotate, and all the sleeves rotate with the tray. During the rotation process, the fiber filaments pulled out of the bobbin are twisted, and the twisted multiple fiber filaments are combined (twisted into one strand) inside the guide sleeve, and are pulled upward around the guide wheel and output, and are introduced into the next process by the wire guide wheel to complete the twisting and winding integrated operation. The speed of the variable frequency speed regulating motor can be adjusted according to the speed of the pulling output to meet the different needs of twisting and winding of different numbers of fiber filaments. Different numbers of bobbins are put in according to the requirements of plying.

The guide sleeve guides all the fiber strands to be twisted and wound faster. The U-shaped limiter prevents the fiber bundle from falling off the wheel after plying, ensuring continuous production. The pressure bearing is set to support the vertical pressure on the vertical rotating shaft.

The second reinforcing rib plate plays a role in enhancing the connection strength between the fixed shaft and the pallet. The third reinforcing rib plate plays a role in enhancing the connection strength between the L-shaped wheel frame and the fixed shaft.

As the bobbin rotates with the tray, it will also reciprocate forward or reverse. The setting of the rotary positioning assembly allows the inner circle of the bobbin to be rollingly connected with the rolling bearing, thereby reducing wear and tear, while reducing the pulling force of the fiber on the bobbin to avoid excessive pulling force and breakage. The setting of the L-shaped wheel frame facilitates the installation and removal of the rolling bearing.

To sum up, the utility model is convenient, fast and highly feasible. It will not cause excessive tension in the fiber filaments and will not cause broken filaments in the twisting process, which facilitates the subsequent production of deformed fibers. It solves the problem of simultaneous twisting and winding of fibers, and the product quality is also well controlled, which provides great help for continuous production.
