Description

Technical Field

[0001] This utility model relates to the field of fabric production equipment technology, and in particular to a warping machine frame yarn changing reminder device. Background Technology

[0002] In modern textile industry, the warping frame is one of the key pieces of equipment. It is used to draw yarn evenly and continuously from the spindles, arrange and wind it onto the warp beam or other carrier in a predetermined manner, preparing it for the subsequent weaving process. Currently, a commonly used structural form is the horizontal placement of the spindles. This layout not only helps to improve space utilization but also facilitates management and maintenance by operators.

[0003] For a warping frame with horizontally placed spindles, each spindle is installed in a specific position and rotates to feed yarn based on the tension applied to the yarn in subsequent processes. However, during production, as the yarn is gradually consumed, the problem of running out of spindles will eventually arise. At this point, in order to ensure continuous production, new, fully loaded spindles must be replaced in a timely manner.

[0004] Many warping machines are now equipped with yarn breakage sensors to monitor yarn condition. These sensors detect the presence of yarn, causing the machine to stop and triggering an alarm to alert operators. However, when a spindle runs out of yarn, it needs to be replaced, and the new yarn must be manually guided through a complex lead-in path to the correct position. This step increases operational complexity and time costs, especially under high-efficiency requirements.

[0005] To address this issue, current solutions include using weighing sensors or cameras to intelligently capture the number of yarns on the spindle. This allows for timely replacement of yarns before they run out, avoiding the need to re-thread the yarns through complex lead-out paths once they are exhausted. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a warping frame yarn change reminder device, which solves the technical problem that existing warping frames do not have yarn change reminder devices installed at the fixed positions of the spindles.

[0007] According to an embodiment of the present invention, a warping frame yarn changing reminder device includes a base and elastic fixing devices evenly distributed on the base. A yarn spindle is fixed on the elastic fixing device, and yarn is wound on the yarn spindle.

[0008] The spindle shaft includes a fixed tube and an elastic rod disposed inside the fixed tube. One end of the elastic rod is provided with a flexible tube, which covers the outside of the fixed tube, and the yarn is wound around the outside of the flexible tube.

[0009] The elastic fixing device includes an elastic element disposed in the middle and a clamping device disposed circumferentially on the outside of the elastic element. The bottom of the fixing tube is fixed on the clamping device, and the elastic element is inserted into the fixing tube to press against the bottom of the elastic rod.

[0010] The technical principle of this utility model is as follows: First, a flexible tube is placed on the outside of a fixed tube for the initial winding. Then, an elastic rod is placed inside the fixed tube, and one end of the elastic rod is fixed to one end of the flexible tube. The fixed tube is then fixed to a clamping device, while the elastic element pushes upward against the elastic rod, giving it an upward force. Then, the normal warping process is carried out. When the yarn is almost used up, the pressure of the yarn winding on the flexible tube decreases. Therefore, the elastic rod will drive the flexible tube to move upward due to the elastic element. At this time, the operator can easily see the protruding section of the elastic rod, thus knowing that the spindle needs to be replaced as soon as possible.

[0011] It should be noted that after the flexible tube moves upward, the yarn on it will also move upward and will not break directly, so it can still maintain normal warping work for a period of time.

[0012] This application uses a purely mechanical mechanism to solve the above problems, which is more cost-effective than using weighing sensors or cameras for intelligent solutions.

[0013] Compared with the prior art, this utility model has the following advantages: by using a spindle shaft formed by a fixed tube, a flexible tube and an elastic rod, and an elastic fixing device with elastic elements, it solves the technical problem that the existing warping machine frame does not have a yarn change reminder device at the fixed position of the spindle, and obtains a yarn change reminder device that is more cost-effective than using a weighing sensor and a camera for intelligent capture.

[0014] Furthermore, the clamping device includes a fixed ring and a clamping piece circumferentially disposed on the fixed ring, the elastic element is disposed at the center of the fixed ring, the clamping piece is hinged to the fixed ring, and a torsion spring is provided at the hinge.

[0015] Furthermore, the bottom outer side of the fixing tube is provided with an annular groove, and the inner side of the clamping plate is evenly distributed with arc-shaped protrusions, which are stuck in the annular groove.

[0016] Furthermore, a rotating bearing is provided on the lower side of the fixed ring, the rotating bearing is mounted on the base, and the elastic element passes through the center of the rotating bearing and is fixed on the base.

[0017] Furthermore, the elastic element is a compression spring.

[0018] Furthermore, the fixed tube has vertically arranged T-shaped grooves evenly distributed around its circumference, and the flexible tube has a locking block at its bottom, which engages with the T-shaped grooves.

[0019] Furthermore, the card block is provided with a convex arc-shaped blade.

[0020] Furthermore, the card block is provided with a mounting hole, the convex arc-shaped blade is installed in the mounting hole, and a spring is provided between the bottom of the mounting hole and the convex arc-shaped blade. Attached Figure Description

Detailed Implementation

One end of the elastic rod 320 is clamped and fixed with a screw to a flexible tube 330. The flexible tube 330 covers the outside of the fixed tube 310, and the yarn is wound around the outside of the flexible tube 330 to form a spindle.

The elastic element 210 is inserted into the fixing tube 310 and presses against the bottom of the elastic rod 320.

[0032] like Figure 2-3 As shown, the clamping device 220 includes a fixed ring 221 and a clamping piece 222 circumferentially disposed on the fixed ring 221. An elastic element 210 is disposed at the center of the fixed ring 221. The clamping piece 222 and the fixed ring 221 are hinged together, and a torsion spring 223 is provided at the hinge to form a clamping structure that can clamp the fixed tube 310.

[0033] Specifically, the bottom outer side of the fixing tube 310 is provided with an annular groove 311, and the inner side of the clamping plate 222 is evenly distributed with arc-shaped protrusions 224. The arc-shaped protrusions 224 are stuck in the annular groove 311 to ensure that the fixing tube 310 is not easy to detach from the clamping plate 222.

[0034] like Figure 2 As shown, a rotating bearing 110 is provided on the lower side of the fixed ring 221. The rotating bearing 110 is mounted on the base 100, and the elastic element 210 passes through the center of the rotating bearing 110 and is welded and fixed on the base 100.
