Description

Technical Field

[0001] The utility model belongs to the field of fiber braided rope weaving, in particular to a fiber braided yarn lead-in device and weaving equipment. Background Art

[0002] Slope protection nets are widely used in areas with landslide risks, such as highways and railways, as well as in mountainous areas and tourist areas, where there's a risk of falling debris. Currently, metal mesh is the most commonly used material. While metal mesh offers strength and durability, long-term exposure to outdoor conditions can lead to corrosion, which can reduce its strength and durability.

[0003] Fiber bundles are yarn bundles composed of multiple continuous fibers. These fiber bundles possess suitable strength and flexibility and can be used to manufacture a variety of textiles and composite materials. Braided ropes woven from fiber bundles are used to create protective nets, which possess a certain degree of flexibility and deformability. This allows the net to conform to the slope surface under complex terrain conditions and effectively cushion the impact of slope collapse, small landslides, or debris flows. Therefore, the use of braided ropes woven from fiber bundles to create slope protection nets has good application prospects.

[0004] When a fiber braided rope is braided, a braiding wheel with a braiding yarn fiber bundle is usually installed on a braiding frame, and then the braiding yarn enters the twisting guide device through the guidance of the wire reel. Under the rotation of the braiding frame and the guidance of the twisting guide device, the braiding yarn is gradually wound onto the core yarn fiber bundle to complete the braiding of the fiber braided rope. When a fiber braided rope is braided, a plurality of braiding grinding wheels are usually fixed on the braiding frame, and the braiding frame is usually disc-shaped. In order to facilitate the guidance of the lead reel, the braiding wheel is usually installed on the braiding frame with the central axis of the braiding wheel perpendicular to the central axis of the braiding frame. However, the installation method in which the central axis of the braiding wheel is perpendicular to the central axis of the braiding frame increases the radial dimension of the braiding frame, resulting in an increase in the overall size of the braiding equipment, which increases the manufacturing cost of the braiding equipment on the one hand and increases the space occupied by the braiding equipment on the other hand.

[0022] The following embodiments are for illustration only and can be combined with each other, and are not limited to the contents presented in the following single embodiments.

[0023] See also Figure 1 、 2The present invention provides a fiber braiding yarn guiding device, comprising: two oppositely arranged mounting posts 1 and a diverter 2; the two mounting posts 1 are spaced apart on a braiding yoke 40, one end of the diverter 2 being connected to the end of one of the mounting posts away from the braiding yoke, and the other end being connected to the end of the other mounting post away from the braiding yoke; the central axis of the diverter 2 being perpendicular to the central axis of the braiding yoke 40; and a guide groove 21 for guiding the braiding yarn fiber bundles being provided on the outer surface of the diverter 2. In this embodiment, a plurality of braiding yarn wheels with braiding yarn fiber bundles are arranged in an annular pattern with the center of the braiding yoke 40 as the center; the central axis of each braiding yarn wheel is parallel to the central axis of the braiding yoke 40, so that when the braiding yarn fiber bundles are removed from the braiding yarn wheel, they are perpendicular to the central axis of the braiding yoke 40. After being diverted by the diverter 2 provided in this embodiment, the braiding yarn fiber bundles can be parallel to the central axis of the braiding yoke 40, so that subsequent braiding equipment can weave a fiber braided rope. In addition, the two mounting posts 1 and the reversing member 2 form a set of braiding yarn fiber bundle reversing components. Each braiding yarn wheel corresponds to a set of braiding yarn fiber bundle reversing components, thereby ensuring that each braiding yarn fiber bundle can be reversed by the braiding yarn fiber bundle reversing components and thus arranged parallel to the central axis of the braiding creel 40. In addition, a guide groove 21 is provided on the outer surface of the reversing member 2 to limit the braiding yarn fiber bundle and prevent the braiding yarn fiber bundle from contacting other structures such as the mounting posts 1 and causing damage to the braiding yarn fiber bundle.

[0024] In one implementation, the diverter 2 can be a diverter wheel, which is rotatably mounted between the two mounting posts 1, thereby reducing the friction between the woven yarn fiber bundle and the diverter 2. Correspondingly, the guide groove 21 is a groove structure provided on the diverter wheel. In this embodiment, the diverter 2 is a cylindrical structure provided with a guide groove 21, which is fixedly connected to the two mounting posts 1; the guide groove 21 includes an outlet section 211 and an inlet section 212, and the cross-section of the outlet section 211 projected perpendicular to the extension direction of the diverter 2 is concave; the two side walls of the outlet section 211 are spirally arranged on the diverter 2; and the groove depth of the guide groove 21 gradually decreases from the connection between the inlet section 212 and the outlet section 211, along the two side walls of the outlet section 211, spirally winding in the spiral direction of the diverter 2. Since the axial and radial positions of the braiding yarn fiber bundle relative to the braiding upper wheel change when the braiding yarn fiber bundle is wound on the braiding yarn wheel, the braiding yarn fiber bundle is guided to the lead-out section 211 through the setting of the introduction section 212 to ensure that the braiding yarn fiber bundle is in the same position after being reversed by the reversing member 2 and entering the first lead disk 3, thereby avoiding the braiding yarn fiber bundle and the first lead disk 3 or other structures not maintaining an ideal connection device, thereby causing damage to the braiding yarn fiber bundle.

[0025] See also Figure 3In one embodiment, the wire guide device further includes a first wire guide reel 3, a second wire guide reel 4, a first support assembly 5 and a second support assembly 6. The first wire guide reel 3 is connected to the weaving yarn frame 40 through the first support assembly 5; the second wire guide reel 4 is connected to the first wire guide reel 3 through the second support assembly 6; the first wire guide reel 3 and the second wire guide reel 4 are respectively provided with a plurality of wire guide holes for passing through the weaving yarn fiber bundles, which are annularly spaced with the center of the first wire guide reel 3 as the center of the circle. The distance between the central axis of the wire guide hole arranged on the first wire guide reel 3 and the central axis of the first wire reel plate is greater than the distance between the central axis of the wire guide hole arranged on the second wire guide reel 4 and the central axis of the second wire reel plate. Specifically, the number of wire guide holes is the same as the number of weaving yarn wheels, and they are arranged in a one-to-one correspondence. By making the distance between the central axis of the wire guide hole provided on the first wire guide reel 3 and the central axis of the first wire reel plate greater than the distance between the central axis of the wire guide hole provided on the second wire guide reel 4 and the central axis of the second wire reel plate, the diameter of the virtual circle formed by the multiple weaving yarn fiber bundles is reduced, making it easier to wind the weaving yarn fiber bundles onto the core yarn fiber bundle. Optionally, in order to reduce the manufacturing cost of the weaving equipment and to facilitate the insertion of the weaving yarn fiber bundles into the wire guide holes on the first wire guide reel 3 or the second wire guide reel 4, the diameter of the first wire guide reel 3 can be larger than the diameter of the second wire guide reel 4 and the diameter of the first wire guide reel 3 can be smaller than the diameter of the weaving yarn frame 40.

[0026] In this embodiment, the first support assembly 5 includes a plurality of first support posts 51, which are spaced apart on the braiding creel 40 and connected to the first thread guide 3 at their ends distal from the braiding creel 40. The second support assembly 6 includes a plurality of second support posts 61, which are spaced apart on the first thread guide 3 and connected to the second thread guide 4 at their ends distal from the braiding creel 40. The arrangement of the first support posts 51 and the second support posts 61 ensures that the first thread guide 3 and the second thread guide 4 rotate synchronously with the rotation of the braiding creel 40. Because the diameter of the first thread guide 3 is larger than that of the second thread guide 4 and smaller than that of the braiding creel 40, the first support posts 51 and the second support posts 61 are positioned nonparallel to the central axis of the braiding creel 40, respectively. This prevents the braiding yarn fiber bundle from contacting the first support posts 51 or the second support posts 61, which could damage the braiding yarn fiber bundle.

[0027] A first through hole for the core yarn fiber bundle to pass through is provided at the center of the first lead-in disk 3 and the second lead-in disk 4. The provision of the first through hole can prevent the rotation of the first lead-in disk 3 and the second lead-in disk 4 from interfering with the core yarn fiber bundle, resulting in damage to the core yarn fiber bundle.

[0028] See also Figure 3On the other hand, the present invention also provides a braiding device, including a fiber braiding yarn lead-in device as described above; further including a base 10, a driving device 20, a core yarn frame 30, a braiding yarn frame 40 and a twisting guide device 50; the driving device 20, the core yarn frame 30, the braiding yarn frame 40 and the twisting guide device 50 are arranged on the base 10; the core yarn frame 30 is used to install a core yarn wheel with a core yarn fiber bundle wound thereon; the braiding yarn frame 40 is used to install multiple braiding yarn wheels with braiding yarn fiber bundles wound thereon, and the braiding yarn frame 40 is also provided with multiple mounting posts 1 and multiple reversing members. 2. Two mounting posts 1 and a reversing member 2 form a set of braiding yarn fiber bundle reversing components. Each braiding yarn wheel is provided with a set of braiding yarn fiber bundle reversing components. The core yarn fiber bundle passes through the first through hole at the center of the first lead disk 3 and the second lead disk 4 in sequence and is connected to the twisting guide device. After the braiding yarn fiber bundle is reversed by the braiding yarn fiber bundle reversing assembly, it passes through the guide holes of the first lead disk 3 and the second lead disk 4 in sequence and is connected to the twisting guide device. The driving device 20 is used to drive the braiding yarn frame 40 to rotate so as to wind the braiding yarn fiber bundle around the core yarn fiber bundle. On the one hand, the twisting guide device plays the role of pulling the braiding yarn fiber bundle and the core yarn fiber bundle, thereby removing the braiding yarn fiber bundle and the core yarn fiber bundle from the grinding wheel. On the other hand, it works together with the driving device 20 to drive the braided fiber braided rope to move away from the guide disk.

[0029] The drive device 20 includes a drive motor 201, a mounting bracket 202, a first rotating shaft 203, a first pulley 204, a second pulley 205, and a belt 206. The drive motor 201 and the mounting bracket 202 are arranged on the base 10. The first rotating shaft 203 is rotatably connected to the mounting bracket 202. One end of the first rotating shaft 203 is connected to the first pulley 204, and the other end is connected to the knitting creel 40. The second pulley 205 is connected to the drive motor 201. The belt 206 is sleeved on the first pulley 204 and the second pulley 205. Specifically, the first rotating shaft 203 is rotatably connected to the mounting bracket 202, and the first pulley 204 and the knitting creel 40 are fixedly mounted on the first rotating shaft 203. The second pulley 205 can be coaxially arranged on the drive shaft of the drive motor 201. The drive motor 201 drives the second pulley 205 to rotate, thereby driving the first rotating shaft 203 to rotate, and driving the knitting creel 40 to rotate.

[0030] In one embodiment, a second through-hole 2031 for passing the core yarn fiber bundle is provided at the center of the first rotating shaft 203. The core yarn fiber bundle passes through the second through-hole 2031 and the first through-hole to connect to the twist guide device. Specifically, the braiding creel 40 is disposed between the core creel 30 and the twist guide device. To facilitate connecting the glass fiber to the twist guide device, the second through-hole 2031 is provided at the center of the first rotating shaft 203.

[0031] In one embodiment, the braided yarn fiber bundles can be made of tough fiber filaments. In this embodiment, the braided yarn fiber bundles are LCP fiber bundles. LCP fiber bundles (LCP stands for liquid crystal polymer) are a type of thermoplastic fiber with a unique molecular structure. They are characterized by high strength, high modulus, excellent heat resistance, and chemical stability. Furthermore, LCP fiber bundles have low water absorption, enabling them to maintain stable performance in humid environments. The core yarn fiber bundles can be made of high-strength glass fiber filaments. In this embodiment, the core yarn fiber bundles are glass fiber bundles. Glass fiber bundles are an inorganic non-metallic material with high strength, high modulus, and corrosion resistance. Furthermore, glass fiber bundles have excellent thermal stability and weather resistance, enabling them to maintain stable performance in various harsh environments. Therefore, the slope protection net woven in this embodiment using LCP fiber bundles (liquid crystal polymer) as the braided yarn and glass fiber bundles as the core yarn fiber cords exhibits high strength, durability, flexibility, and excellent corrosion resistance, effectively improving the protective effectiveness of the slope protection net.

[0032] In summary, the present invention reverses the direction of the braided yarn fiber bundle wound on a braided yarn wheel whose central axis is parallel to the central axis of the braiding frame 40 by providing a mounting post 1 and a reversing member 2, thereby making the braided yarn fiber bundle parallel to the central axis of the braiding frame 40, thereby reducing the manufacturing cost of the braiding equipment and reducing the space occupied by the braiding equipment. In addition, a guide groove 21 is provided on the reversing member 2 to limit the braided yarn fiber bundle and prevent the braided yarn fiber bundle from contacting other structures such as the mounting post 1, thereby causing damage to the braided yarn fiber bundle. Therefore, the present invention effectively overcomes the various shortcomings of the prior art and has high industrial utilization value.

[0033] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention.
