Description

Technical Field

[0001] This invention relates to the field of circular loom technology, and more specifically to a circular loom wire feeder. Background Technology

[0002] A circular loom is an industrial device used for weaving tube fabric. The warp frame of a circular loom has many spindles, and a specified number of warp yarns are used based on the width of the fabric and the width of the flat yarn. Before entering the circular loom, the warp yarns are crossed by the warp frame, and the weft shuttle moves in a circular motion through the openings to pass through the warp yarns, weaving the fabric into tubes. A circular loom mainly consists of a frame, a transmission system, and a warp system. The yarn feeder, also known as the warp frame, is a device on the circular loom used to support and transport the yarn. It is usually composed of a steel pipe or shaped steel frame with yarn feed rods arranged on the frame to ensure that the yarn is supplied to the weaving area of ​​the circular loom in an orderly and stable manner.

[0003] In existing circular looms, the yarn feeder stably delivers yarn to the weaving area via yarn feed rods. These rods are elastic, allowing them to move in sync with the fabric end, adjusting the yarn tension and providing appropriate tension to ensure proper yarn control during transport, preventing weaving problems caused by slack or excessive tension. However, the multiple yarn feed rods, each relying on their own deformation to increase tension, result in inconsistent movement amplitudes and uneven yarn tension, leading to wrinkles on the fabric surface. Summary of the Invention

[0004] The present invention aims to provide a thread feeder for a circular loom, which solves the problem in the prior art where the amplitude of the swaying of multiple thread feed rods is inconsistent and the yarn tension is uneven, resulting in wrinkles on the surface of the woven product.

[0005] To address the above problems, the present invention provides the following technical solution: A circular loom wire feeder includes a frame, the frame having a fixed annular skeleton, the skeleton having multiple rotating handles uniformly and coaxially rotatably connected along the circumference, each rotating handle having multiple wire feed rods fixedly at even intervals; it also includes a connecting ring abutting against the bottom of the multiple rotating handles, the frame having a fixed cylinder for driving the connecting ring to move up and down.

[0006] The working principle and beneficial effects of this invention: In this technical solution, since the rotating handle and the frame are rotatably connected, and the connecting ring and the bottom of all the rotating handles abut against each other, the connecting ring is driven to move up and down by the cylinder. The connecting ring pushes all the rotating handles to rotate up and down, and the rotating handles drive all the thread feeding rods to swing up and down. Since all the thread feeding rods swing up and down with the same amplitude, compared with the existing technology, the thread feeding rods do not rely on their own deformation to swing, thereby making the yarn tension uniform, ensuring that there are no wrinkles on the surface of the woven products, and improving the quality of the woven products.

[0007] Ideally, each of the thread feed rods has an annular portion at its top. When the circular loom is working, multiple yarns are introduced into the annular portion at the top of each thread feed rod, and the other end of the yarn is introduced into the weaving end of the circular loom. The annular portion serves to pull the yarn and adjust its tension.

[0008] Ideally, the connecting ring has a hollow internal structure, and a rotating ring is coaxially rotatably connected to the connecting ring. A motor that drives the rotating ring to rotate is fixed inside the connecting ring. The connecting ring has two sliding ports along the circumferential direction that are opposite to the corresponding rotating handle. A top rod that abuts against the bottom of the rotating handle is vertically slidably connected to the sliding port. A pushing block that pushes the top rod to slide up and down is fixed on the rotating ring. The height of the pushing block gradually decreases along the circumferential direction of the rotating ring.

[0009] The rotating ring is driven by a motor, which in turn drives the push block to rotate. By changing the height of the push block, the upward pressure exerted on the push rod is altered, thus changing the height of the push rod outside the connecting ring. The push rod supports the rotating handle, which is movable. This allows adjustment of the height of the rotating handle at one end of the push rod. For example, by reducing this height, the tilt angle of all the thread feed rods on the rotating handle is changed, making the initial tilt angle larger. When the connecting ring moves upward under the action of the cylinder, the connecting ring, through the push rod, compresses the rotating handle to rotate. Because the initial tilt angle of all the thread feed rods on this rotating handle is different from that on other rotating handles, the tension of the yarn on each thread feed rod on this rotating handle is different, thus creating a wrinkled product to meet the needs of special applications.

[0010] Ideally, a spring is fixed between the push rod and the sliding port. The spring is used to accelerate the descent speed of the push rod within the sliding port.

[0011] Ideally, the push rod is positioned near the center of the corresponding rotating handle. This optimization prevents the push rod from detaching during the process of lifting the rotating handle.

[0012] Ideally, the feed rod has a certain curvature. This curvature facilitates the connection between the yarn and the fabric end. Attached Figure Description

Detailed Implementation

[0014] The following detailed description illustrates the specific implementation method: The reference numerals in the accompanying drawings include: frame 1, rotating handle 2, cylinder 3, wire feed rod 4, connecting ring 5, push rod 6, motor 7, push block 8, rotating ring 9, and bevel gear 10.

[0015] In the following statements, directional terms such as "left," "right," "up," and "down" are based on the directions shown in the diagram. In practice, if the corresponding structures are changed in the same direction based on the direction while maintaining their relative positions, it will not affect the implementation of the plan.

[0016] Example 1: A wire feeder for a circular loom, referring to... Figure 1 The device includes a frame (not shown in the figure), which is fixedly equipped with a ring-shaped skeleton 1. The skeleton 1 is uniformly and coaxially connected to 6 rotating handles 2 along the circumference. Each rotating handle 2 is uniformly spaced and fixedly equipped with 3 wire feeding rods 4. The device also includes a connecting ring 5 that abuts against the bottom of the 6 rotating handles 2. The frame is fixedly equipped with a cylinder 3 that drives the connecting ring 5 to move up and down.

[0017] like Figure 2 and Figure 3 As shown, in this technical solution, since the rotating handle 2 and the frame 1 are rotatably connected, and the connecting ring 5 abuts against the bottom of all the rotating handles 2, the cylinder 3 drives the connecting ring 5 to move up and down, and the connecting ring 5 pushes all the rotating handles 2 to rotate up and down. The rotating handle 2 drives all the thread feeding rods 4 to swing up and down. Since all the thread feeding rods 4 swing up and down with the same amplitude, compared with the prior art, the thread feeding rods 4 do not rely on their own deformation to swing, thereby making the yarn tension uniform, ensuring that there are no wrinkles on the surface of the woven product, and improving the quality of the woven product.

[0018] Example 2: The difference from Example 1 is that: Refer to Figure 5 , Figure 4 and Figure 6As shown, the connecting ring 5 has a hollow internal structure. A rotating ring 9 is coaxially rotatably connected to the connecting ring 5. A motor 7, which drives the rotating ring 9, is fixedly installed inside the connecting ring 5. Specifically, a bevel gear 10 is coaxially fixedly sleeved at the bottom of the rotating ring 9, and the motor 7 drives a helical gear meshing with the bevel gear 10. The connecting ring 5 has sliding openings along its circumference opposite to the two rotating handles 2. Push rods 6 are vertically slidably connected to these sliding openings, respectively abutting against the bottoms of the two rotating handles 2. A push block 8 is fixedly installed on the rotating ring 9 to push the push rods 6 up and down. Figure 8 As shown, the height of the pushing block 8 gradually decreases along the circumference of the rotating ring 9.

[0019] like Figure 7 As shown, the rotating ring 9 is driven to rotate by the motor 7, and the rotating ring 9 drives the push block 8 to rotate. By changing the height of the push block 8, that is, changing the upward pressing amplitude of the push block 8 on the top rod 6, the height of the top rod 6 outside the connecting ring 5 is changed. The top rod 6 is used to support the rotating handle 2, which is movable, thereby adjusting the height of the rotating handle 2 at one end of the top rod 6. For example, by reducing this height, the tilt angle of all the thread feeding rods 4 on the rotating handle 2 is changed, making the initial tilt angle larger. When the connecting ring 5 moves upward under the action of the cylinder 3, the connecting ring 5 presses the rotating handle 2 to rotate through the top rod 6. Since the initial tilt angle of all the thread feeding rods 4 on this rotating handle 2 is different from that of all the thread feeding rods 4 on other rotating handle 2, the tension of the yarn on all the thread feeding rods 4 on this rotating handle 2 is different from that on other rotating handle 2, thus weaving a product with pleats to meet the needs of special occasions.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
