A quadruple twist spindle tension adjustment device

Abstract

The present invention discloses a tension adjustment device for a four-for-one twisting spindle, belonging to the technical field of textile machinery components. The device comprises a tensioner fixing tube, a spindle flyer, a capsule tensioner, a core shaft, a tension adjustment tube, a tension spring, an upper tension bowl, and a lower tension bowl. Compared with existing tension adjustment devices for four-for-one twisting spindles, the present device has a simpler structure. The device replaces the traditional two-for-one twisting spindle's balloon tension adjustment component, which is located inside the yarn supply bobbin (in the middle of the spindle), with a balloon tension adjustment component located outside the yarn supply bobbin (on the top of the spindle), adapting to the yarn path. This results in a wider tension adjustment range.

Description

Technical Field

[0001] The invention belongs to the technical field of textile machinery component devices, and in particular relates to a quadruple twist spindle tension regulating device. Background Art

[0002] From the single twist of traditional twisting machines to the double twist of the currently widely used two-for-one twisting machines, although there has been a great improvement in production efficiency, it still does not meet people's expectations. Therefore, technicians have continuously carried out the research and development of four-for-one twisting machines. The key to the research and development of four-for-one twisting machines is the research and development of four-twist spindles. In the past, many technicians have also carried out the research and development of four-for-one twisting spindles, but so far it has not been industrialized. During the specific use or operation of the four-for-one twisting spindle, its balloon tension must be adjusted and controlled, otherwise normal production cannot be carried out. Since the structure and yarn path of the four-for-one twisting spindle are quite different from those of the traditional two-for-one twisting spindle, its tension adjustment device must be able to adapt to the particularity of this structure and yarn path. The tension adjustment device of the four-for-one twisting spindle and the four-for-one twisting spindle can be fully combined into a four-for-one twisting machine. Summary of the Invention

The bottom of the tensioner fixing tube is inserted into the center hole of the yarn supply drum; the core shaft is supported in the inner hole at the top of the tensioner fixing tube by stacking and passing through the first bearing 3 and the second bearing 4. The top of the core shaft is in the shape of an open bowl, and the lower tension bowl is arranged on the top of the core shaft. A yarn guide port is provided on the side of the core shaft, and the flyer is supported below the yarn guide port. The top of the lower tension bowl is in the shape of an open bowl, and the side of the lower tension bowl is provided A yarn guide hole connected to the yarn guide port, and the yarn guide hole is connected to the open top of the core shaft; the capsule tensioner is arranged at the top opening of the core shaft, and the upper tension bowl is arranged on the top of the capsule tensioner, and the bottom of the upper tension bowl is in the shape of an open bowl that matches the top of the capsule tensioner, and the bottom of the tension adjustment tube is a trumpet-shaped opening and has a step surface, the top surface of the upper tension bowl is fixed on the step surface, and the top outlet of the tension adjustment tube serves as the yarn outlet 17, and the bottom of the tension spring is abutted against the abutment portion on the outer side of the lower section of the tension adjustment tube, and the tension spring is supported by a tension tube for fixing the tension adjustment tube.

[0017] Preferably, the tension tube includes an upper tension tube 15, a middle tension tube 14, and a lower tension tube 12. The bottom of the upper tension tube is a trumpet-shaped opening, the lower section of the tension adjustment tube is accommodated in the trumpet-shaped opening, the top of the middle tension tube is embedded and fixed between the tension adjustment tube and the inner wall of the upper tension tube, the capsule tensioner is accommodated in the middle tension tube, the lower tension tube is fixedly sleeved on the lower section of the middle tension tube, the side of the lower tension tube is provided with a yarn inlet 11 connected to the yarn guide port, and the bottom of the lower tension tube is fitted and sleeved on the top of the core shaft. The core shaft is made of alumina. The flyer is fixedly mounted on the core shaft through the flyer seat 5, and the top of the upper tension tube is provided with a tension ring seat 16.

[0018] When working, the fixed tube is connected to the bobbin of the yarn supply bobbin and is stationary during the working process.

The flyer seat is fixedly connected to the core shaft, and the core shaft is fixedly connected to the tension lower tube. The yarn inlet is set on the tension lower tube. Due to the need for yarn guiding, the yarn inlet must be facing the flyer. During the yarn unwinding process, the tension adjustment part installed on the core shaft, including the flyer, yarn inlet, etc., will rotate synchronously along the yarn unwinding direction to achieve yarn unwinding. There are two specific aspects of tension adjustment: one is the thickness of the spring wire diameter inside the capsule tensioner, which has a total of four specifications. Springs of different specifications have different elastic forces, thereby applying different forces to the yarn. The second is to adjust the compression amount of the tension adjustment spring by adjusting the different positional relationships of the tension adjustment tube, thereby applying different yarn tensions to the capsule tensioner. See the structure of the tension adjustment tube. Figure 4, with numbers 1, 2, 3, 4, and 5 engraved on the top, and corresponding to the numbers 1, 2, 3, 4, and 5, there are grooves of different heights below. By adjusting different positions, different compression amounts of the tension adjustment spring can be obtained, thereby applying different yarn tensions to the capsule tensioner to achieve the purpose of adjusting the tension.
