Description

Technical Field

[0001] This utility model relates to the field of textile equipment, and more specifically to a warp traction assist device for a circular loom. Background Technology

[0002] Circular looms are used for weaving tube fabrics. The overall machine structure is circular, with a main shaft in the center. The main shaft is equipped with the main weaving mechanism, which rotates to perform the weaving process. In existing technology, the warp threads are fed to the central weaving mechanism through the warp frames on both sides via an active traction mechanism. The active traction mechanism is located close to the weaving mechanism, providing good power for the warp threads to enter the weaving mechanism. However, when the warp threads are output from the warp frames, they are far from the active traction mechanism, which causes a large pulling force on the warp threads, which may damage the warp threads or affect the normal and smooth delivery of the warp threads. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a warp traction assist device for a circular loom. By setting the assist mechanism near the output position of the warp frame, it provides auxiliary power for the conveying of warp threads, making the conveying of warp threads smoother and more orderly, and avoiding damage to the warp threads during traction.

[0004] This utility model provides the following technical solution: a warp traction assist device for a circular loom, including a weaving mechanism located in the middle and a warp beam located on the side of the weaving mechanism for storing warp threads. An active traction mechanism is provided between the weaving mechanism and the warp beam to provide power for conveying the warp threads. An assist mechanism is provided on the upper part of the warp beam. The assist mechanism includes an assist motor, an assist roller, and an auxiliary roller. The assist motor is connected to the assist roller for power drive rotation. The warp threads are output from the warp beam and pass through the assist roller and the auxiliary roller in sequence, and then pass through the active traction mechanism to the weaving mechanism.

[0005] As an improvement, the assist mechanism also includes two side support plates, with the assist roller and auxiliary roller rotatably disposed between the two side support plates, and the assist motor mounted on one side support plate and connected to the assist roller.

[0006] As an improvement, one end of the assist roller is mounted on a side support plate via a bearing, and the other end of the assist roller is connected to the motor shaft of the assist motor via a coupling.

[0007] As an improvement, the side support plate has vertically set waist-shaped adjustment holes, and the two ends of the auxiliary roller are rotatably set at the waist-shaped adjustment holes. The tension of the warp is changed by adjusting the height of the auxiliary roller at the waist-shaped adjustment holes.

[0008] As an improvement, several cross braces are also installed between the two side support plates to increase structural strength.

[0009] As an improvement, a transition roller is also installed above the active traction mechanism at the same height as the auxiliary mechanism. After the warp thread passes around the auxiliary roller, it first passes through the transition roller and then goes down around the active traction mechanism.

[0010] The beneficial effects of this utility model are as follows: By setting an auxiliary mechanism near the output position of the warp frame, auxiliary power is provided for the conveying of warp threads. The traction and conveying of warp threads are achieved through the cooperation of the auxiliary mechanism and the active traction mechanism, making the conveying of warp threads smoother and more orderly, avoiding jamming and damage to warp threads during traction, and ensuring product quality.

[0012] Figure 2 This is a three-dimensional structural diagram of the present invention. Detailed Implementation

[0013] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0014] like Figure 1 , 2 The image shows a specific embodiment of the warp traction assist device for a circular loom of this utility model. This embodiment includes a weaving mechanism 01 located in the middle and a warp beam 02 located on the side of the weaving mechanism 01 for storing warp threads. An active traction mechanism 04 is provided between the weaving mechanism 01 and the warp beam 02 to provide power for conveying the warp threads. An assist mechanism 1 is provided on the upper part of the warp beam 02. The assist mechanism 1 includes an assist motor 2, an assist roller 3, and an auxiliary roller 4. The assist motor 2 is connected to the assist roller 3 for power-driven rotation. The warp threads are output from the warp beam 02 and sequentially pass over the assist roller 3 and the auxiliary roller 4, then pass over the active traction mechanism 04 to the weaving mechanism 01.

[0015] In use, the main support of the circular loom forms a frame. A weaving mechanism 01 is located in the middle of the main support, and an active traction mechanism 04 is positioned on both sides of the lower part of the weaving mechanism 01. A warp beam 02 is located outside the active traction mechanism 04, and an auxiliary mechanism 1 is located at the upper warp output position of the warp beam 02. The warp threads stored in the warp beam 02 are pulled out in an orderly manner to the auxiliary mechanism 1, pass over the auxiliary roller 2, and then pass under the auxiliary roller 3. After passing through the active traction mechanism 04, they reach the weaving mechanism 01. After the weaving process is completed at the weaving mechanism 01, the woven fabric is conveyed to the upper winding mechanism (not shown in the figure) for winding. This invention utilizes the auxiliary mechanism 1 providing traction power near the warp beam 02 and the active traction mechanism 04 providing traction power near the weaving mechanism 01, working together to achieve smoother and more orderly warp thread transport, preventing jamming and damage during traction, and ensuring product quality.

[0016] As an improved specific implementation, the assist mechanism 1 also includes two side support plates 5, the assist roller 3 and the auxiliary roller 4 are rotatably disposed between the two side support plates 5, and the assist motor 2 is mounted on one side support plate 5 and connected to the assist roller 3.

[0017] like Figure 2 As shown, two side support plates 5 are installed on the main body bracket on both sides to provide mounting brackets for the auxiliary motor 2, the auxiliary roller 3 and the auxiliary roller 4. The auxiliary motor 2 is installed on the outside of the side support plate 5 on one side. The motor extends axially inward and connects to the auxiliary roller 3 to provide power. The auxiliary roller 3 and the auxiliary roller 4 are arranged in parallel at a roughly horizontal position for the warp to be wound.

[0018] As an improved specific implementation, one end of the assist roller 3 is mounted on a side support plate 5 via a bearing 7, and the other end of the assist roller 3 is connected to the motor shaft of the assist motor 2 via a coupling 6.

[0019] like Figure 2 As shown, one end of the auxiliary roller 3 is connected to the motor shaft of the auxiliary motor 2 through the coupling 6 structure to transmit power and rotate, while the other end rotates smoothly through the bearing 7.

[0020] As an improved specific implementation, the side support plate 5 has a vertically arranged waist-shaped adjustment hole 8, and the two ends of the auxiliary roller 4 are rotatably arranged at the waist-shaped adjustment hole 8. The tension of the warp is changed by adjusting the height of the auxiliary roller 4 at the waist-shaped adjustment hole 8.

[0021] like Figure 2As shown, the assist force of the assist mechanism 1 can be adjusted through the arrangement of its structure and components. The assist force is adjusted by changing the speed of the assist motor 2; increasing the speed of the assist motor 2 increases the assist force on the warp threads, while decreasing the speed of the assist motor 2 decreases the assist force on the warp threads. In this embodiment, the assist force is adjusted by changing the height of the auxiliary roller 4. Lowering the position of the auxiliary roller increases the tension of the warp threads passing underneath, while raising the position of the auxiliary roller decreases the tension of the warp threads passing underneath, thus reducing the assist force. Height adjustment is achieved by providing waist-shaped adjustment holes 8. After the two ends of the auxiliary roller 4 pass through the waist-shaped adjustment holes 8, they can be rotatably set via a bearing structure. The outer shell of the bearing structure is then locked or limited to the side support plate 5 by fasteners. When height adjustment is needed, the fasteners are loosened, and the auxiliary roller 4 is raised or lowered. Once the desired height is reached, it is locked again.

[0022] As an improved specific implementation, several cross braces 9 are also installed between the two side support plates 5 to increase the structural strength.

[0023] like Figure 2 As shown, the cross brace 9 stabilizes the spacing between the two side support plates 5, making the support structure stable, thereby ensuring the stability of the mounting structure of the auxiliary roller 3 and the auxiliary roller 4; preferably, two cross braces 9 can be set, with the two cross braces 9 respectively set on the front and rear sides, thereby ensuring the stability and firmness of the structure.

[0024] As an improved specific implementation, a transition roller 03 is also provided above the active traction mechanism 04 at the same height as the auxiliary mechanism 1. After the warp thread passes around the auxiliary roller 4, it first passes through the transition roller 03 and then goes down around the active traction mechanism 04.

[0025] like Figure 1 As shown, after the warp yarn is drawn out from the warp yarn frame 02, it passes over the top of the auxiliary roller 2, then passes under the auxiliary roller 3, passes through the transition roller 03, and then goes down to the active traction mechanism 04, finally entering the weaving mechanism 01. With the help of the transition roller 03, the warp yarn first runs horizontally at the height of the auxiliary mechanism 1, passes over the transition roller 03, and then goes down to the active traction mechanism 04. The yarn runs more orderly, which is convenient for on-site management and the orderly traction of the warp yarn.

[0026] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
