AI Technical Summary
[0002]飞行器天线罩是以石英纤维为原材料的编织产品，其编织过程多是通过编织机进行，其中，由于经纱数量众多，根据工艺要求，经纱的一端是按顺序钩挂在经纱架成排且层叠状的挂齿上；编织过程中，经纱放纱操作必须通过人工逐排（逐层）、逐齿按顺序进行；即，由操作工将第一排（层）挂齿上经纱逐一手动推出，实现第一层放纱动作，然后第二排（层）、第三排（层）如此重复动作，直至完成全部排（层）的放纱操作；由此导致生产效率较低，人工成本高；另一方面，由于采用人工进行放纱操作，一定程度上会影响经纱分布的均匀性，进而影响天线罩的编织质量
该放纱装置，结构简单、实用性好，即可通过程序控制，亦可通过人工进行控制。工作过程中，通过气缸B、气缸A的依次动作，完成全部60个挂纱杆的放纱操作，由此解决了现有人工进行放纱操作，一定程度上影响经纱分布的均匀性，进而影响天线罩编织质量的问题。

Abstract
Description
Technical Field
[0001] This utility model relates to a yarn feeding device, specifically a yarn feeding device for an antenna radome weaving machine. Background Technology
[0002] Aircraft radomes are woven products made from quartz fiber. The weaving process is primarily carried out using a weaving machine. Due to the large number of warp yarns, according to process requirements, one end of each warp yarn is hooked sequentially onto rows and layers of teeth on a warp rig. During weaving, the warp yarn release operation must be performed manually, row by row (layer by layer), tooth by tooth in sequence. That is, the operator manually pushes out the warp yarns one by one from the first row (layer) of teeth, completing the first layer's release, and then repeating this process for the second and third rows (layers) until all rows (layers) are released. This results in low production efficiency and high labor costs. Furthermore, the manual release operation can affect the uniformity of warp yarn distribution, thus impacting the radome's weaving quality. Based on these shortcomings, improvements are necessary. Summary of the Invention
[0003] The purpose of this utility model is to provide a yarn feeding device for a yarn cover weaving machine that is simple in structure, practical, and can effectively improve work efficiency and weaving quality.
[0004] The technical solution of this utility model is: A yarn feeding device comprises an assembly base, an assembly rod, a linear slide rail, a yarn hanging bracket, cylinder A, cylinder B, and a yarn hanging rod. Its features include: an assembly rod fixedly mounted on the assembly base; a yarn hanging bracket horizontally mounted on the assembly rod via an mounting block; a linear slide rail fixedly mounted on one end face of the yarn hanging bracket; cylinder A mounted on the slider of the linear slide rail via an mounting plate; cylinder B mounted on the piston rod end of cylinder A; a yarn hanging rod mounting block fixedly mounted on the yarn hanging bracket at the front end of the linear slide rail; and multiple yarn hanging rods mounted on the yarn hanging rod mounting block.
[0005] The piston rod end of cylinder B is equipped with a yarn hook block.
[0006] The hook block is long and narrow, with an arc-shaped hook at one end.
[0007] The yarn hanging rods are arranged in parallel at intervals on the yarn hanging rod mounting block.
[0008] The beneficial effects of the utility model are as follows: This yarn-feeding device has a simple structure and good practicality. It can be controlled by a program or manually. During operation, the sequential action of cylinder B and cylinder A completes the yarn-feeding operation of all 60 yarn-hanging rods. This solves the problem that the existing manual yarn-feeding operation affects the uniformity of warp yarn distribution to a certain extent, thus affecting the quality of radome weaving.

[0011] The yarn feeding device of this radome braiding machine consists of an assembly base 1, an assembly rod 2, a linear slide rail 3, a yarn hanging bracket 4, a cylinder B6, and a yarn hanging rod 7. The assembly base 1 is fixedly mounted with the assembly rod 2. The yarn hanging bracket 4 is horizontally mounted on the assembly rod 2 via an mounting block 9. A servo motor-driven linear slide rail 3 is fixedly mounted on the rear end face of the yarn hanging bracket 4. A cylinder A5 is mounted on the slider of the linear slide rail 3 via a mounting plate 10. The cylinder A5 is installed at an angle of less than 40 degrees. The piston rod end of the cylinder A5 is fitted with a cylinder B6. The piston rod end of the cylinder B6 is fitted with a yarn hook block 8. The yarn hook block 8 is elongated, and one end of the yarn hook block 8 has a semi-circular arc-shaped recess 12.
[0012] A yarn hanging rod mounting block 11 is fixedly installed on the yarn hanging bracket 4 at the front end of the linear slide rail 3, and multiple yarn hanging rods 7 are installed in parallel and spaced on the yarn hanging rod mounting block 11.
[0013] The yarn feeding device has 60 yarn hanging rods 7, which are installed at an angle on the yarn hanging rod mounting block 11, and the installation angle corresponds to the installation angle of the cylinder A5.
[0014] During operation, the yarn feeding device is first fixed to the weaving equipment via the mounting base 1. This yarn feeding device can be controlled by a program or manually. After installation, the warp yarns are manually layered, and then the 60 layers of warp yarns are hung one by one on the 60 yarn hanging rods 7 in sequence (from left to right). Taking manual control as an example, during operation, the linear slide rail 4 moves in a reciprocating linear motion under the drive of the servo motor. Since the slide rail is equipped with a cylinder A5 via the mounting plate 10, and the piston rod end of cylinder A5 is equipped with a cylinder B6; and the piston rod end of cylinder B6 is equipped with a yarn hook block 8. This drives cylinder A5, cylinder B6, and yarn hook block 8 to move linearly along the linear slide rail 3.
[0015] When the slider moves to the position corresponding to the first yarn hanging rod 7 (first layer of warp yarn), the servo motor stops; press the solenoid valve switch of cylinder A5, and the piston rod of cylinder A5 extends; when cylinder B6 at the end of the piston rod of cylinder A5 moves to the position of the first yarn hanging rod 7 (first layer of warp yarn) and stops, close the solenoid valve switch of cylinder A5, and the piston rod of cylinder A5 stops moving; at this time, press the solenoid valve switch of cylinder B6, and the piston rod of cylinder B6 extends downward, and the yarn hook block 8 at its end moves downward according to the set step amount, when... When the hook block 8 moves to the warp yarn bundle opening and contacts it, the arc-shaped recess 12 engages with the first hanging rod 7. At this point, cylinder B6 is closed, and cylinder A5 is activated again. This pushes the entire warp yarn bundle outside the first hanging rod 7 by the sliding motion of the hook block 8 on the hanging rod 7, completing the yarn release operation. After the yarn release operation of the first hanging rod 7 is completed, cylinders B6, A5, and the slider are reset sequentially. Then the second, third, and so on are performed on the second and third hanging rods 7, and so on, until all 60 hanging rods 7 have completed their yarn release operations. This yarn release device has a simple structure and good practicality. By sequentially actuating cylinders B6 and A5, it completes the yarn release operation of all 60 hanging rods, thus solving the problem of existing manual yarn release operations affecting the uniformity of warp yarn distribution and, to some extent, the quality of radome weaving. It is particularly suitable for installation and use on radome weaving machines.
