Description

A tensioner connection structure for a doubling twister Technical Field

[0001] This utility model relates to the field of textile machinery parts technology, specifically a tensioner connection structure for a twisting machine. Background Technology

[0002] The tensioner of a twisting machine is a key component in textile machinery used to control yarn tension. Especially in twisting machines, its function directly affects yarn quality, production efficiency and equipment stability. The tensioner of a twisting machine is usually assembled from four parts, including an upper shell, a lower shell, a plastic inner core and a spring.

[0003] In existing bullet-shaped tensioners on the market, the inner core and lower shell are connected together by an adhesive. In the complex environment of actual production of a twisting machine, factors such as temperature changes, periodic vibrations, and high humidity can easily cause the adhesive to fail, resulting in the lower shell falling off, which in turn affects the production efficiency of textiles. Summary of the Invention

[0004] This utility model provides a tensioner connection structure for a twisting machine, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tensioner connection structure for a twisting machine, comprising an upper shell, a lower shell and an inner core disposed directly below the upper shell, the inner core being located in the middle of the upper and lower shells, a spring disposed inside the inner core, an outer buckle disposed at the opening of the lower shell, and multiple inner buckles disposed at the opening of the inner core, the lower shell and the inner core being interlocked by the outer and inner buckles.

[0006] As a preferred technical solution of this application, the upper shell has a groove inside, and the inner core has a protruding edge outside, and the upper shell and the inner core are fitted together by the groove and the protruding edge.

[0007] As a preferred technical solution of this application, the inner core surface is provided with a frosted surface and an exhaust plane.

[0008] As a preferred technical solution of this application, the outer edge of the buckle is set as an arc surface, and the inner edge of the buckle is an arc-shaped raised surface.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. The tensioner connection structure of this twisting machine, by setting a lower shell, inner core, outer buckle, and inner buckle, allows the inner core to be quickly assembled with the lower shell through the inverted buckle structure formed by the outer and inner buckles. The inverted buckle structure mechanically fixes the lower shell and inner core together, and can be used in conjunction with traditional adhesives for secondary fixation, further ensuring the firmness of the installation. At the same time, the inverted buckle mechanism can prevent the lower shell and inner core from falling off after the adhesive fails, thereby avoiding the impact on textile production efficiency due to tensioner failure.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] As shown in Figures 1-7, this utility model provides a tensioner connection structure for a twisting machine, including an upper shell 1, a lower shell 2 and an inner core 3 located directly below the upper shell 1, the inner core 3 being located in the middle of the upper shell 1 and the lower shell 2, and a spring 4 disposed inside the inner core 3. An outer buckle 5 is disposed at the opening of the lower shell 2, and multiple inner buckles 6 are disposed at the opening of the inner core 3. The lower shell 2 and the inner core 3 are interlocked by the outer buckles 5 and the inner buckles 6. By setting the lower shell 2, inner core 3, outer buckles 5, and inner buckles 6, this connection structure, through the inverted structure formed by the outer buckles 5 and the inner buckles 6, allows for quick assembly of the inner core 3 and the lower shell 2, and mechanical fixation of the lower shell 2 and the inner core 3 through the inverted structure. It can be used in conjunction with traditional adhesives for secondary fixation, further ensuring the stability of the installation. Simultaneously, the inverted mechanism can prevent the lower shell 2 and the inner core 3 from detaching after the adhesive fails, thereby avoiding the impact on textile production efficiency due to tensioner failure.

[0022] The upper shell 1 has a groove 7 inside, and the inner core 3 has a protruding edge 8 on the outside. The upper shell 1 and the inner core 3 are fitted together by the groove 7 and the protruding edge 8. By setting the protruding edge 8 and the groove 7, it is convenient to install and connect the upper shell 1 and the inner core 3. The inner core 3 is tightly fitted into the cavity of the upper shell 1 by the protruding edge 8 on the upper shell 3, which can prevent the upper shell 1 and the inner core 3 from falling off.

[0023] The inner core 3 has a frosted surface 9 and an exhaust surface 10. The frosted surface 9 can be used to cooperate with the inverted structure of the lower shell 2 and the inner core 3, thereby further improving the installation firmness. The structure is simple and convenient for mass production. In addition, the exhaust surface 10, compared with conventional air guide holes, can effectively prevent adhesive from entering the inner cavity of the inner core 3 and avoid the adhesive from affecting the extension and contraction of the spring 4.

[0024] The edge of the outer buckle 5 is set as an arc surface, and the edge of the inner buckle 6 is an arc-shaped raised surface. By setting both the edges of the outer buckle 5 and the inner buckle 6 as arc surfaces, the smoothness of the arc surface makes it easier for the outer buckle 5 and the inner buckle 6 to overlap when the inner core 3 is connected to the lower shell 2, ensuring installation efficiency. Furthermore, the raised arc surface can limit the outer buckle 5, ensuring the firmness of the installation and preventing it from falling off.

[0025] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
