Description

Technical Field

[0001] This utility model relates to the field of textile tensioning, and in particular to a multi-directional tensioning device. Background Technology

[0002] Textiles are softer and more easily damaged than other rolled materials, making tension control particularly crucial. Currently, most textile equipment does not adequately consider tension control in the initial design phase, typically adding it as a supplementary design later. Traditional tension controllers are usually fixed to one side of the equipment or directly mounted on it, primarily using a single-sided feeding method. After internal tensioning, the output comes from one side of the controller. This fixed structure is usually used with specific equipment as a dedicated tensioning mechanism; however, it is often difficult to adapt when temporary adjustments to the tension direction or the textile feeding direction are needed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a multi-directional tensioning device that solves the problem that existing tension controllers have fixed structures and cannot adapt to temporary adjustments of the tensioning direction or the textile feeding direction.

[0004] According to an embodiment of the present invention, a multi-directional tensioning device includes a support portion, the support portion having a central tensioning portion and at least one inlet portion and one outlet portion disposed on one side of the tensioning portion, the central tensioning portion including at least one tensioner that is not collinear with the inlet portion and the outlet portion.

[0005] Preferably, the central tensioning part includes a fixed frame fixedly disposed at the center of the support part, the fixed frame having at least two extended tensioning arms, each tensioning arm being provided with a tensioning wheel, the tensioning wheel being controlled by an elastic mechanism to reciprocate along the direction of the tensioning arm.

[0006] Preferably, the inlet and outlet portions are provided with at least one set of guide wheels.

[0007] Preferably, the angle between the tensioning arms is adjustable.

[0008] Preferably, the tensioning arm is cross-shaped.

[0009] Preferably, the elastic mechanism includes a rectangular groove on the tensioning arm, a slider in the rectangular groove, springs connected to both ends of the rectangular groove on both sides of the slider, a rotating shaft in the middle of the slider, and a tensioning wheel on the rotating shaft.

[0010] Preferably, the support portion is rectangular, and guide wheels are respectively provided at the four corners of the rectangle, forming an entry portion and an exit portion between the guide wheels.

[0011] Preferably, the support portion is provided with a mounting portion.

[0012] Preferably, a support member is provided at the bottom of the support portion.

[0013] This invention can achieve tensioning at different angles by adjusting the direction of the support part or the relative position of the tensioning arm with the inlet and outlet parts. It has a simple and lightweight structure, can change the position of the inlet and outlet parts, and can be adjusted at any time. It is suitable for various processes that require temporary adjustment of the tensioning direction or the textile feeding direction. Attached Figure Description

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] A multi-directional tensioning device includes a support portion 1, the support portion 1 being provided with a central tensioning portion and at least one inlet portion and one outlet portion disposed on one side of the tensioning portion, the central tensioning portion including at least one tensioner that is not collinear with the inlet portion and the outlet portion.

[0020] Generally, the inlet and outlet sections are equipped with at least one set of guide wheels 4 to facilitate the entry and exit of objects that need to be tensioned (taking yarn as an example below).

[0021] In some cases, the support part 1 can be a structure with an internal cavity, and the inlet and outlet parts are perforated structures. In this case, the edges of the inlet and outlet parts can be used directly as guides.

[0022] When using it, the yarn is introduced from the inlet, goes around the central tensioning part, and then comes out from the outlet. It should be noted that, regardless of where the inlet and outlet are located, after the yarn goes around the central tensioning part, it must form an angle with the object to be tensioned as the vertex in order to achieve the tensioning effect.

[0023] In a preferred embodiment of this utility model, such as Figure 1As shown, the central tensioning part includes a fixed frame fixedly installed at the center of the support part 1. The fixed frame has at least two extended tensioning arms 2. Tensioning wheels 3 are provided on the tensioning arms 2. The tensioning wheels 3 are controlled by an elastic mechanism to reciprocate along the direction of the tensioning arms 2. After the yarn is introduced from the inlet, it passes around the tensioning wheels 3 and then reaches the outlet. Due to the action of the elastic mechanism, the yarn can also be tensioned during the movement.

[0024] In some cases, the angle between the tensioning arms 2 can be adjusted to accommodate different tensioning angles and to adjust the degree of tension. The tensioning arms 2 can be adjusted by rotating one end to be fixed in the middle of the support part 1, and then fixing it with a set screw after rotating to a certain angle. The tensioning arms 2 can also be designed as an integrally formed cross shape, and reinforcing plates can be installed on the tensioning arms 2 to connect the various tensioning arms 2 in series to improve stability.

[0025] In a preferred embodiment of this utility model, such as Figure 2 As shown, the elastic mechanism includes a rectangular groove on the tensioning arm 2, a slider 6 inside the rectangular groove, springs 5 ​​on both sides of the slider 6 connected to the two ends of the rectangular groove, a rotating shaft 7 in the middle of the slider 6, and a tensioning wheel 3 mounted on the rotating shaft 7. During the spinning process, the force generated can be buffered by the springs 5 ​​to achieve a further tensioning effect.

[0026] In a preferred embodiment of this utility model, such as Figure 1 As shown, the support part 1 is rectangular, and guide wheels 4 are respectively set at the four corners of the rectangle. Four channels are formed between the guide wheels 4, all of which can act on the inlet and outlet parts. This structure can rotate arbitrarily, making it easy to adjust the direction, and tension can be achieved regardless of which direction the yarn enters. Figure 3 Several tensioning methods are shown. Since the structure is symmetrical, the tensioning methods for yarn entering from other directions are basically similar and will not be shown one by one.

[0027] In a preferred embodiment of this utility model, the support part 1 is provided with an installation part, which can be a fixing hole, to facilitate installation on a machine.

[0028] In a preferred embodiment of the present invention, a support member is provided at the bottom of the support part 1, which can fix the multi-directional tensioning device on the ground.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
