Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to a feeding device for processing flexible alloy micro-wires. Background Art

[0002] Currently, ultrafine metal microfilaments are more rigid than standard textile threads, but far less flexible and stronger than standard textile threads. When used on existing textile equipment, these microfilaments are prone to breakage. This is primarily due to the significant wear and tear caused by the microfilaments. When worn to a certain degree, textile equipment can easily damage the microfilaments, leading to breakage and frayed threads, which in turn affects the efficiency and quality of textile production.

[0003] The prior art textile industry feeding device can refer to a textile machine auxiliary feeding device with publication number CN221026829U, which was publicly authorized on May 28, 2024. The device includes a storage unit with multiple support rods for installing yarns; a feeding unit arranged on one side of the storage unit, the feeding unit including a power assembly and a buckle assembly, the yarns are detachably sleeved on the buckle assembly, the buckle assembly is used to bring multiple yarns together, the power assembly is connected to the buckle assembly and drives the buckle assembly to move; and a controller is electrically connected to the power assembly and is used to drive the power assembly to operate. This device can improve the feeding efficiency of textile machine yarns and reduce labor costs.

[0004] In actual use, this type of existing commonly used feeding device has not been adapted to the metal microwires and cannot be directly applied to the processing of flexible alloy microwires. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to:

[0006] 1. Provide a feeding device suitable for flexible alloy micro-wire processing, so that it can adjust the tension of the metal micro-wire to maintain uniformity during startup, use and shutdown, and reduce the phenomenon of metal micro-wire twisting and breaking.

[0007] 2. Provide a feeding device suitable for processing flexible alloy micro-wires, which has some easily replaceable parts that come into direct contact with the metal micro-wires, thereby reducing the probability of the metal micro-wires being worn off through the form of replaceable parts.

[0008] To achieve the above objectives, the present invention provides the following technical solutions:

[0009] A feeding device for processing flexible alloy microwires includes a feeding rack and a feeding rod. The feeding rod is rotatably connected to the feeding rack. The feeding rack is provided with a first device, and the first device is located on one side of the feeding rod. The first device includes at least two intermediate rods, and a distance adjustment device is also provided between the two intermediate rods to extend or shorten according to the tension of the alloy microwire.

[0010] This solution ensures the alloy filament's tension remains within the designed range by adjusting the spacing between the two intermediate rods using a distance adjustment device. This distance adjustment device can be a purely mechanical spring-based structure, or a closed-loop control mechanism in which a sensor transmits a tension signal to a processor, which then sends a signal to activate a motor. Compared to the simple tension adjustment devices used in existing textile yarns, this design minimizes the angular variation of the alloy filaments when controlling their tension, making them less susceptible to breakage.

[0011] Optionally, the intermediate rod includes a rod body and a roller arranged on the rod body.

[0012] Optionally, a spring is further provided between the rod body and the roller, and the spring is sleeved on the rod body.

[0013] The spring controls the position of the roller on the rod. When the material output position on the feeder changes, the alloy wire deviates, causing the roller to shift on the rod. The spring controls the degree of the roller's shift.

[0014] Optionally, a compression strip is further provided on one end of the rod body near the roller, and the compression strip is rotatably connected to the rod body. A compression groove corresponding to one end of the compression strip is provided on the top surface of the roller, and a blocking end is extended from the other end of the compression strip, and a blocking groove corresponding to the blocking end is provided on one end of the rod body.

[0015] Optionally, a clamping spring is further provided at the rotational connection between the pressing strip and the rod body.

[0016] Optionally, the side surface of the roller is a concave curved surface.

[0017] The beneficial technical effect of the utility model is that the distance between the two middle rods is adjusted by the distance adjustment device to ensure that the tension of the alloy microwire is within the designed range, thereby reducing the breakage of the alloy microwire during the prevention process.

[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom," "top," "inner," and "outer" refer to directions toward or away from the geometric center of a particular component, respectively.

[0023] Reference Figure 1-3 As shown, a feeding device for processing flexible alloy micro-wires includes a feeding frame 1 and a feeding rod 2. The feeding rod 2 is rotatably connected to the feeding frame 1. The feeding frame 1 is provided with a first device, which is located on one side of the feeding rod 2. The first device includes at least two intermediate rods, and a distance adjustment device 4 is further provided between the two intermediate rods to extend or shorten the wire according to the tension of the alloy micro-wire 3.

[0024] The middle rod comprises a rod body 5 and a roller mounted on the rod body 5. The roller has a concave curved side surface. A spring 7 is also interposed between the rod body 5 and the roller, and is sleeved onto the rod body 5. Specifically, the end of the rod body 5 facing away from the roller has a raised step for one end of the spring 7 to rest against, and the roller has a recessed surface for the other end of the spring 7 to rest against.

[0025] A compression strip 8 is also provided on the end of the rod 5 near the roller, which is rotatably connected to the rod 5. A compression groove is provided on the top surface of the roller, corresponding to one end of the compression strip 8. A blocking end extends from the other end of the compression strip 8, and a blocking groove corresponding to the blocking end is provided on one end of the rod 5. A clamping spring is also provided at the rotatable connection between the compression strip 8 and the rod 5.

[0026] When in use, first insert the reel 9 with alloy microwire 3 into the feeding rod 2, draw out the alloy microwire 3 on the reel and pass it around the rollers, making it form a "Z"-shaped track between the rollers. After being drawn out of the rollers, it is connected to the subsequent process to complete the loading.

[0027] This solution ensures the tension of the alloy filament 3 remains within the designed range by adjusting the spacing between the two intermediate rods using a spacing adjustment device 4. Specifically, this spacing adjustment device 4 can be a purely mechanical structure with a spring 7 as its core, or a closed-loop control structure in which a sensor transmits a tension signal to a processor, which then sends a signal to activate a motor. Compared to the simple tension adjustment devices used in existing textile yarns, this design minimizes the angular variation of the alloy filament 3 when controlling its tension, making it less susceptible to twisting and breaking.

[0028] In this solution, the design of spring 7 and elastic pressure strip 8 controls the position of the roller on the rod 5. When the material output position on the feeder changes, the alloy filament 3 deviates, causing the roller to shift on the rod 5. The spring 7 controls the degree of this displacement. In this solution, the elastic pressure strip 8 not only stabilizes the relative angle between the rod 5 and the roller, but also cooperates with the spring 7 to control the offset position of the roller 6 on the rod 5.

[0029] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
