Description

Technical Field

[0001] The utility model relates to the field of yarn racks, and particularly to a yarn rack for carbon fiber cloth production. Background Art

[0002] According to different uses and materials, yarn racks can be divided into various types, such as wooden yarn racks, metal yarn racks, plastic yarn racks, wall-mounted yarn racks, column-mounted yarn racks, etc. At present, in the production of carbon fiber cloth, yarn racks are often used to wind the carbon fiber cloth. Existing yarn racks usually include parts such as a frame and yarn bobbins. The yarn bobbins are installed on the frame.

[0003] Existing yarn racks also have the following problems: The weight and volume of the yarn rack are relatively large, and the yarn rack is divided into a frame part and a yarn bobbin part. The frame part is usually an integrally formed structure and cannot be disassembled. When disassembling and installing the yarn bobbins, multiple people may be required to cooperate. The yarn bobbins are usually composed of a rotating shaft and a roller. The two ends of the rotating shaft are inserted into the frame and fixed by fasteners such as screws, so that the rotating shaft passes through both ends of the frame and rotates around the frame. The roller is also fixed by fasteners such as screws, so that the roller is installed on the rotating shaft. Therefore, during the handling process, it is difficult to install and disassemble the entire yarn rack, and it is inconvenient to disassemble the yarn rack into multiple parts for handling. Secondly, during the winding process, a driving mechanism such as a driving motor is connected to the outside of the yarn bobbin, and the yarn bobbin is rotated by the driving motor for winding. Moreover, the surface of the yarn bobbin is usually smooth, and the carbon fiber cloth is difficult to closely adhere to the yarn bobbin due to insufficient friction and too fast a speed of the driving motor driving the yarn bobbin during winding, resulting in the carbon fiber cloth being prone to looseness and falling off during the winding process, easily causing the winding process of the carbon fiber cloth to terminate and making it impossible to closely adhere to and fix the carbon fiber cloth.

Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0020] Such as Figures 1-6As shown in the figure, a yarn rack for carbon fiber cloth production includes a support frame 1 and a yarn rolling cylinder 2. The yarn rolling cylinder 2 is located above the support frame 1. The surface of the support frame 1 is provided with a number of square grooves 9. A number of detachable connecting rods 5 are arranged between the support frames 1. The two ends of the connecting rod 5 extend outwards respectively to form insertion blocks 13. The side surface of the insertion block 13 extends outwards to form a fitting portion 14. The inner wall of the fitting portion 14 is in mutual fit with the surface of the support frame 1. The surface of the insertion block 13 extends outwards to form an insertion portion 15. The insertion portion 15 is inserted into the square groove 9. The surface of the insertion portion 15 is in mutual fit with the surface of the square groove 9. The yarn rolling cylinder 2 is sleeved with a rotating shaft 3. The rotating shaft 3 extends outwards and passes through both ends of the yarn rolling cylinder 2. The rotating shaft 3 is sleeved with a shaft sleeve 4. The rotating shaft 3 and the shaft sleeve 4 are fixedly connected. There is a clearance fit connection between the shaft sleeve 4 and the yarn rolling cylinder 2. The clearance fit connection between the shaft sleeve 4 and the yarn rolling cylinder 2 effectively reduces the friction and wear during the rotation process. And due to the clearance fit, the yarn rolling cylinder 2 can be conveniently detached from the shaft sleeve 4, which is convenient for the installation and disassembly of the yarn rolling cylinder 2. The surface of the support frame 1 is provided with a U-shaped groove 8. Both ends of the rotating shaft 3 extend into the U-shaped groove 8 respectively. The rotating shaft 3 and the U-shaped groove 8 are rotatably connected. By setting the U-shaped groove 8, it is convenient to install the rotating shaft 3. The rotating shaft 3 can rotate inside the U-shaped groove 8. At the same time, the rotating shaft 3 can be detached by a direct disassembly method, so as to facilitate the subsequent replacement of the yarn rolling cylinder 2. The side surface of the yarn rolling cylinder 2 extends outwards to form an arc-shaped block 10 and a clamping block 11. A clamping groove 12 is formed between the arc-shaped block 10 and the clamping block 11. By setting the clamping groove 12, the front end of the carbon fiber cloth can be clamped to prevent the carbon fiber cloth from loosening during the winding process.

[0021] The surface of the support frame 1 extends outwards to form a vertical rod 7. The vertical rod 7 is perpendicular to the connecting rod 5. The surface of the support frame 1 is provided with two positioning rods 6. The positioning rods 6 and the support frame 1 form a triangular shape. The positioning rods 6 and the support frame 1 are integrally formed. By setting the vertical rod 7 and the positioning rods 6, the overall strength of the support frame 1 can be enhanced, further enhancing the overall support stability of the yarn rack, so that the yarn rack can still remain stable when carrying a large amount of carbon fiber cloth. At the same time, using the stability principle of the triangle, the structural strength of the yarn rack is significantly enhanced, effectively resisting deformation and damage under the action of external forces. There are eight square grooves 9 and four connecting rods 5.

[0022] A yarn rack for producing carbon fiber cloth in this embodiment enables the insertion part 15 to be inserted into the square groove 9 through the setting of the square groove 9, facilitating the installation and disassembly of the connecting rod 5 and the support frame 1. The installation and disassembly of the rotating shaft 3 are facilitated through the setting of the U-shaped groove 8. The winding roller 2 is connected with a clearance fit through the bushing 4, facilitating the installation and disassembly of the winding roller 2. The overall adopts a modular assembly method, which can divide the yarn rack into multiple parts, facilitating the installation and disassembly of the entire yarn rack. Through the clamping groove 12 provided between the arc-shaped block 10 and the clamping block 11, the front end of the carbon fiber cloth can be fixed, preventing the carbon fiber cloth from loosening and falling off during the winding process.
