Description

A yarn guiding mechanism for a fiber braiding machine Technical Field

[0001] This utility model relates to the field of fiber braiding machine technology, specifically to a yarn guiding mechanism for a fiber braiding machine. Background Technology

[0002] As core production equipment in textiles, composite materials and other fields, fiber weaving machinery directly affects weaving efficiency and finished product quality through the stability and cleanliness of its yarn guiding mechanism. However, during high-speed weaving, especially when processing materials that are prone to pilling such as cotton and chemical fibers, fibers that fall off the yarn surface tend to accumulate in the guiding area.

[0003] Existing fiber braiding machines (such as the 130-16-2 hemp rope braiding machine) involve weaving and winding spools of cotton yarn along a reversing track via a reversing mechanism at the bottom of the braiding frame. The woven yarn then passes through a guide ring for guidance and is limited before being further processed by the top reversing roller. During high-speed braiding, especially when processing easily fuzzy materials like cotton or synthetic fibers, fibers detached from the yarn surface tend to accumulate in the bottom reversing mechanism area. These loose fibers adhere to the guide wheels or the bottom reversing track area, not only polluting the working environment but also potentially clogging the bottom yarn changing track, requiring frequent machine stops for cleaning and reducing production efficiency. Therefore, an improved yarn guiding mechanism for fiber braiding machines is needed to address these issues. Summary of the Invention

[0004] The purpose of this invention is to provide a yarn guiding mechanism for a fiber braiding machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a yarn guiding mechanism for a fiber braiding machine, including a mounting frame, a guide tube fixedly mounted on the front of the mounting frame, a guiding mechanism at the bottom of the guide tube, and a cleaning mechanism at the top of the guide tube.

[0006] Preferably, the guiding mechanism includes a first fixing frame, which is fixedly installed at the bottom of the guide tube, and a first guide wheel is rotatably installed inside the first fixing frame. A second fixing frame is fixedly installed at the bottom of the guide tube, and a second guide wheel is rotatably installed inside the second fixing frame. A third fixing frame is fixedly installed at the top of the guide tube, and a third guide wheel is rotatably installed inside the third fixing frame.

[0007] Preferably, the first fixing frame, the first guide wheel, the second fixing frame, and the second guide wheel are symmetrically distributed around the center line of the front of the guide tube.

[0008] Preferably, the cleaning mechanism includes an electrostatic adsorption ring, which is fixedly installed on the top of the guide tube. An installation sleeve is provided on the top of the electrostatic adsorption ring, and a locking block is fixedly installed on the bottom of the installation sleeve. A tearable lint remover is provided inside the installation sleeve.

[0009] Preferably, the electrostatic adsorption ring has a slot at the corresponding position of the card block, and the card block is engaged inside the slot.

[0010] Preferably, the interior of the tearable lint paper is coated with high-adhesion silicone.

[0011] Preferably, the tearable lint paper has a multi-layered spiral structure, with pre-cut lines on the edges of each layer, and adjacent layers are separated by a weak adhesive coating.

[0012] Compared with the prior art, the present invention provides a yarn guiding mechanism for a fiber braiding machine, which has the following advantages:

[0013] 1. In the operation of this fiber braiding machine yarn guiding mechanism, the guide wheel three, the bottom guide wheel one, and the guide wheel two form a triangular tension distribution structure to prevent the braided yarn from rubbing against the inner wall of the guide tube and to ensure the stability of the yarn exit trajectory. The top guide wheel three serves as the final guiding node to ensure the stability of the braided yarn entering subsequent processes.

[0014] 2. The yarn guiding mechanism of this fiber braiding machine uses an electrostatic field to attract scattered fibers during use, reducing scattering pollution. It also utilizes a tearable lint-adhesive paper inside the mounting sleeve to physically adhere the electrostatically captured fibers. The mounting sleeve features a snap-fit ​​design, allowing for tool-free disassembly and easy replacement of the lint-adhesive paper. The lint-adhesive paper has a multi-layered spiral structure, with pre-cut lines on the edges of each layer, and adjacent layers are separated by a weakly adhesive coating, enabling rapid layer peeling, reducing replacement frequency, and lowering consumable costs.

[0024] Please refer to Figures 1-3. This utility model provides a technical solution: a yarn guiding mechanism for a fiber braiding machine, including a mounting frame 1, a guide tube 4 fixedly mounted on the front of the mounting frame 1, a guiding mechanism 2 provided at the bottom of the guide tube 4, and a cleaning mechanism 3 provided at the top of the guide tube 4.

[0025] Furthermore, the guiding mechanism 2 includes a first fixing frame 21, which is fixedly installed at the bottom of the guide tube 4. A first guide wheel 22 is rotatably installed inside the first fixing frame 21. A second fixing frame 23 is fixedly installed at the bottom of the guide tube 4. A second guide wheel 24 is rotatably installed inside the second fixing frame 23. A third fixing frame 25 is fixedly installed at the top of the guide tube 4. A third guide wheel 26 is rotatably installed inside the third fixing frame 25. This prevents the woven yarn from rubbing against the inner wall of the guide tube 4 and ensures the stability of the yarn exit trajectory, thus protecting the woven yarn.

[0026] Furthermore, the fixing frame 1 21, guide wheel 1 22, fixing frame 23, and guide wheel 24 are symmetrically distributed around the center line of the front of the guide tube 4. Guide wheel 3 26, together with the bottom guide wheel 1 22 and guide wheel 24, forms a triangular tension distribution structure to ensure the stability of the cable trajectory. Example

[0027] Please refer to Figure 4 and, in conjunction with Embodiment 1, further illustrate that the cleaning mechanism 3 includes an electrostatic adsorption ring 31, which is fixedly installed on the top of the guide tube 4. An installation sleeve 32 is provided on the top of the electrostatic adsorption ring 31, and a locking block 33 is fixedly installed on the bottom of the installation sleeve 32. A tearable lint-adhesive paper 34 is provided inside the installation sleeve 32. The lint-adhesive paper 34 adsorbs scattered fibers through the electrostatic field, reducing scattered pollution, and physically adheres the fibers captured by electrostatic force using the tearable lint-adhesive paper 34 inside the installation sleeve 32.

[0028] Furthermore, the electrostatic adsorption ring 31 has a slot at the corresponding position of the locking block 33, and the locking block 33 is engaged inside the slot. The mounting sleeve 32 adopts a snap-on design, which can be disassembled without tools.

[0029] Furthermore, the tearable lint 34 is coated with high-adhesion silicone to adhere fibers and reduce scattering pollution.

[0030] Furthermore, the tearable lint 34 has a multi-layer spiral stacked structure, with pre-cut lines on the edges of each layer, and adjacent layers are separated by a weak adhesive coating, enabling rapid layer peeling, reducing replacement frequency, and lowering consumable costs.

[0031] In actual operation, when this device is used, it is installed in the original guide frame position of the fiber braiding machine through the pre-drilled mounting holes on the surface of the mounting frame 1. During the braiding of cotton thread, the finished product enters the guide tube 4 through the guide wheel 1 22 and guide wheel 24, and then is guided by guide wheel 3 26 to enter the subsequent operation process. The electrostatic adsorption ring 31 is activated. After the cotton thread fibers are braided at high speed, the fibers on the surface of the yarn will fall off. The scattered fibers are adsorbed by the electrostatic field to reduce the scattering pollution. The tearable lint paper 34 set inside the mounting sleeve 32 physically adheres to the fibers captured by electrostatics, adsorbing the fibers on the surface of the tearable lint paper 34 to reduce fiber scattering. After the braiding is completed, the tearable lint paper 34 can be peeled off to clean the adhered fibers.

[0032] After the tearable adhesive tape 34 is used up, pull the locking block 33 outward to disengage the mounting sleeve 32 from the locking limit of the electrostatic adsorption ring 31, and replace the mounting sleeve 32, that is, replenish the tearable adhesive tape 34, in preparation for subsequent fiber pasting.

[0033] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
