Description

Technical Field

[0001] The utility model belongs to the field of fiber braided rope weaving, in particular to a transmission device of a braiding machine and the braiding machine. 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 weaving fiber ropes, a braiding machine is usually used. The braiding machine usually includes a base, a core yarn frame, a mounting bracket, a braiding yarn frame, and a driving device for driving the braiding yarn frame to rotate. The core yarn frame, the mounting bracket, and the driving device are mounted on the base. The driving device includes a rotating shaft and a driving member. The rotating shaft is rotatably connected to the mounting bracket, one end of the rotating shaft is directly or indirectly connected to the driving member, and the other end is connected to the braiding yarn frame, and the central axis of the braiding yarn frame is usually arranged parallel to the horizontal plane. However, according to the weaving needs of different braided ropes, the braiding yarn frame is fixed with multiple braiding wheels with braiding yarn fiber bundles wound on the braiding yarn frame. The braiding yarn wheels and the braiding yarn frame are usually heavy. In the prior art, the braiding yarn frame is only rotatably connected to the mounting bracket via a rotating shaft. When in use, due to the weight of the braiding yarn wheels and the braiding yarn frame, the central axis of the braiding yarn frame is tilted relative to the horizontal plane, so that the power of the driving member cannot be effectively transmitted to the braiding yarn frame.

[0031] See also Figure 1-2 The utility model provides a transmission device of a braiding machine, comprising: a base 1, a driving mechanism, a mounting bracket 3, a braiding yoke 100 and a limiting mechanism 4; the driving mechanism and the mounting bracket 3 are arranged on the base 1; the driving mechanism comprises a first rotating shaft 21 and a driving member 22, the driving member 22 is arranged on the base 1, the first rotating shaft 21 is rotatably connected to the mounting bracket 3, one end of the first rotating shaft 21 is connected to the driving member 22, and the other end is connected to the braiding yoke 100; the limiting mechanism 4 comprises a first limiting member 41 and at least three second limiting members 42; the first limiting member 41 is arranged on the braiding yoke 100, the first limiting member 41 is arranged on the braiding yoke 100, and the second limiting member 42 is arranged on the braiding yoke 100. A limiting member 41 is an annular structure, and a first protrusion 411 and a second protrusion 412 are arranged on the outer surface of the first limiting member 41, and a first limiting gap 413 is formed between the first protrusion 411 and the second protrusion 412; at least three second limiting members 42 are arranged at intervals on the mounting bracket 3, and a third protrusion 421 and a fourth protrusion 422 are arranged on the outer surface of the second limiting member 42, and a second limiting gap 423 is formed between the third protrusion 421 and the fourth protrusion 422; the first limiting gap 413 is used to accommodate the fourth protrusion 422; the second limiting gap 423 is used to accommodate the first protrusion 411.

[0032] The mounting bracket 3 may be provided with a mounting hole for the first rotating shaft 21 to pass through, and a bearing may be provided within the mounting hole. The first rotating shaft 21 is rotatably connected to the mounting bracket 3 via the bearing. The first stopper 41 is an annular structure, specifically a cylindrical structure having an internal clearance hole for the first rotating shaft 21. The first protrusion 411 and the second protrusion 412 may be annularly arranged on the outer surface of the first stopper 41. The first stopper 41 and the knitting creel 100 may be integrally formed or separately formed and then mounted together using a fixing structure such as bolts, which is not limited in this embodiment. The number of second stoppers 42 may be three, with three second stoppers 42 spaced apart on the mounting bracket 3 in a triangular pattern. Alternatively, the number may be four or more, forming a polygonal structure, or spaced apart in an annular pattern on the mounting bracket 3, which is not limited in this embodiment. The second stopper 42 may be a cylindrical structure, and the third protrusion 421 and the fourth protrusion 422 may be annularly arranged on the outer surface of the second stopper 42. In one embodiment, the groove depth of the first limiting gap 413 is equal to the groove depth of the second limiting gap 423, and the groove width of the first limiting gap 413 is equal to the groove width of the second limiting gap 423, that is, the interval between the first protrusion 411 and the second protrusion 412 is equal to the interval between the third protrusion 421 and the fourth protrusion 422, and the height of the first protrusion 411 and the second protrusion 412 protruding from the first limiting member 41 is equal to the height of the third protrusion 421 and the fourth protrusion 422 protruding from the second limiting member 42. The first protrusion 411 extends deep into the second limiting gap 423 and abuts against the groove bottom of the second limiting gap 423, as well as the side wall of the first protrusion 411 and the side wall of the second limiting gap 423. Similarly, the fourth protrusion 422 extends deep into the first limiting gap 413 and abuts against the groove bottom of the first limiting gap 413, as well as the side wall of the fourth protrusion 422 and the side wall of the first limiting gap 413, thereby preventing the braiding creel 100 from moving up and down or left and right relative to the horizontal plane. That is, the braiding creel 100 can only rotate relative to the mounting bracket 3 and cannot move. This prevents the braiding creel 100 from moving up and down or left and right relative to the horizontal plane when the twisting guide module pulls the braiding yarn fiber bundle during subsequent braiding. The driving member 22 can be a motor, which drives the first rotating shaft 21 to rotate, thereby driving the mounting bracket 3 to rotate.

[0033] In this embodiment, at least three second limiting members 42 are provided on the mounting bracket 3 and a first limiting member 41 is provided on the weaving yarn frame 100. The weaving yarn frame 100 is limited by a first protrusion 411, a second protrusion 412 and a first limiting gap 413 formed between the first protrusion 411 and the second protrusion 412 provided on the first limiting member 41, and a third protrusion 421 and a fourth protrusion 422 provided on the second limiting member 42 and a second limiting gap 423 formed between the third protrusion 421 and the third protrusion 421. On the one hand, it ensures that the central axis of the weaving yarn frame 100 will not tilt relative to the horizontal plane, and ensures that the rotational power of the driving member 22 can be effectively transmitted to the weaving yarn frame 100, thereby ensuring the stability of the operation of the weaving machine. On the other hand, the cooperation of the first protrusion 411 and the second limiting gap 423 and the cooperation of the fourth protrusion 422 and the first limiting gap 413 can also prevent the weaving yarn frame 100 from moving up and down and left and right relative to the horizontal plane.

[0034] See also Figure 1-5 In one embodiment, the second stopper 42 is rotationally connected to the mounting bracket 3. When the driving member 22 drives the knitting creel 100 to rotate, the rotation of the knitting creel 100 drives the first stopper 41 to rotate. Since the second stopper 42 and the mounting bracket 3 are rotationally connected, the rotation of the first stopper 41 can drive the first stopper 41 to rotate, thereby reducing the friction between the first stopper 41 and the second stopper 42, thereby avoiding significant wear on the first and second stoppers 42. Specifically, the second stopper 42 and the mounting bracket 3 can be connected via a second rotating shaft 43. Specifically, the second rotating shaft 43 is provided with a bearing, and the second rotating shaft 43 is connected to the second stopper 42 via the bearing.

[0035] Please continue reading Figure 3-5In one embodiment, the limiting mechanism 4 further includes a plurality of adapter plates 44, a plurality of limiting pins 45 and a plurality of fixing members 46; the second rotating shaft 43, the adapter plate 44, the limiting pin 45 and the second limiting member 42 are arranged in a one-to-one correspondence; the number of fixing members 46 is twice the number of the second limiting members 42; two fixing members 46 are arranged for each second limiting member 42; the mounting bracket 3 is provided with a plurality of first waist-shaped holes 31 for the second rotating shaft 43 to pass through and a plurality of second waist-shaped holes 32 for the fixing members 46 to pass through; the second rotating shaft 43 is provided with a first through hole 431 for the limiting pin 45 to pass through The adapter plate 44 is provided with a second through hole 441 for the limiting pin 45 to pass through, a third through hole 442 for the second rotating shaft 43 to pass through, and a fourth through hole 443 for the fixing member 46 to pass through; one end of the second rotating shaft 43 is rotatably connected to the second limiting member 42, and the other end is connected to the adapter plate 44 after passing through the first waist-shaped hole 31 and the third through hole 442; the limiting pin 45 passes through the second through hole 441 and the first through hole 431 to fix the second rotating shaft 43 on the adapter plate 44; the fixing member 46 passes through the third through hole 442 and the second waist-shaped hole 32 to fix the adapter plate 44 on the mounting bracket 3. The adapter plate 44 can be a rectangular plate-shaped structure. The third through hole 442 is located at the center of the adapter plate 44. The second through hole 441 is located on a side surface of the adapter plate 44 and is connected to the third through hole 442. Two fourth through holes 443 are provided, symmetrically arranged on the adapter plate 44 with the third through hole 442 as the center. The first through hole 431 is located on the side of the second rotating shaft 43 and extends through the second rotating shaft 43. The fixing part 46 can be a bolt and nut structure. When in use, first pass the second rotating shaft 43 through the first waist-shaped hole 31, then pass the second rotating shaft 43 through the adapter plate 44, and align the first through hole 431 of the second rotating shaft 43 and the second through hole 441 of the adapter plate 44, and insert the limit pin 45 to fix the adapter plate 44 and the first rotating shaft 21. Finally, align the fourth through hole 443 of the adapter plate 44 and the second waist-shaped hole 32, and then pass the screw of the bolt through the fourth through hole 443 and the second waist-shaped hole 32 in sequence, and then use the nut to fix the adapter plate 44 on the mounting bracket 3 to fix the second rotating shaft 43 on the mounting plate. In this embodiment, the second rotating shaft 43 is fixed to the mounting bracket 3 by setting a first waist-shaped hole 31, a second waist-shaped hole 32, a limit pin 45, an adapter plate 44 and a fixing part 46. The position of the second limit part 42 can be adjusted by using the setting of the first waist-shaped hole 31 and the second waist-shaped hole 32 to ensure that the second limit part 42 can abut against the first limit part 41.

[0036] See also Figure 1The drive mechanism further includes a first pulley 23, a second pulley 24, and a belt 25. The first pulley 23 is connected to the drive member 22, and the second pulley 24 is connected to the end of the first rotating shaft 21 away from the knitting creel 100. The belt 25 is sleeved on the first pulley 23 and the second pulley 24. In other words, in this embodiment, the drive member 22 drives the first rotating shaft 21 to rotate via the belt 25 transmission mechanism. The first pulley 23 and the second pulley 24 can be provided with a plurality of belt 25 grooves for sleeved with the belt 25. A plurality of corresponding belts 25 are also provided, and the belts 25 are arranged in a one-to-one correspondence with the belt 25 grooves to improve transmission efficiency and stability.

[0037] See also Figure 1 、 6 7. In one embodiment, the transmission device further includes a support mechanism 5 for supporting an LCP braiding yarn fiber bundle guide disk 200; the support mechanism 5 is disposed on the base 1 and abuts against the outer side surface of the LCP braiding yarn fiber bundle guide disk 200. When the braiding machine braids a braided rope, the LCP braiding yarn fiber bundle guide disk 200 is typically used to guide the braiding yarn fiber bundle to the twisting guide module. At the same time, the LCP braiding yarn fiber bundle guide disk 200 is connected to the braiding creel 100 via a support column. That is, when the driving member 22 drives the first rotating shaft 21 to rotate, the first rotating shaft 21 drives the braiding creel 100 and the LCP braiding yarn fiber bundle guide disk 200 to rotate as a whole. Since there is usually a certain distance between the LCP braiding yarn fiber bundle guide disk 200 and the braiding yarn frame 100, if the LCP braiding yarn fiber bundle guide disk 200 is suspended in the air, the braiding machine will run unsteadily and the central axis of the braiding yarn frame 100 will be tilted with the horizontal plane. Therefore, this embodiment introduces a support mechanism 5 for supporting the LCP braiding yarn fiber bundle guide disk 200, which is used to support the LCP braiding yarn fiber bundle guide disk 200 and prevent the LCP braiding yarn fiber bundle guide disk 200 from being suspended in the air.

[0038] Specifically, the support mechanism 5 includes a support seat 51 and a support slot 52; the support seat 51 is disposed on the base 1, and the support slot 52 is disposed on the top of the support seat 51, and is configured to abut against the outer side surface of the LCP braided yarn fiber bundle guide disk 200. The bottom and sidewalls of the support slot 52 can abut against the sidewalls of the LCP braided yarn fiber bundle guide disk 200 to support the LCP braided yarn fiber bundle guide disk 200. To reduce friction between the support slot 52 and the LCP braided yarn fiber bundle guide disk 200, in this embodiment, a plurality of rolling elements 53 are disposed within the support slot 52 for abutting against the outer side surface of the LCP braided yarn fiber bundle guide disk 200, thereby reducing the contact area between the support slot 52 and the LCP braided yarn fiber bundle guide disk 200. The rolling element 53 can be a metal ball structure, which is arranged on the bottom of the support groove 52 or on the sidewall of the support groove 52. Specifically, a receiving groove 54 for accommodating the rolling element 53 can be provided on the sidewall and bottom of the support groove 52, and a closing member 55 for closing the receiving groove 54 can be provided on the support seat 51. During installation, the rolling element 53 is first placed in the receiving groove 54, and then the receiving groove 54 is closed by the closing member 55 to prevent the rolling element 53 from rolling out of the receiving groove 54. The closing member 55 can be a plate-shaped structure, which is used to close one end of the receiving groove 54. In an optional embodiment, the receiving groove 54 can be provided only on the bottom of the support groove 52 to accommodate the rolling element 53, or can be provided only on the sidewall of the support groove 52 to accommodate the rolling element 53. Of course, the receiving groove 54 can also be provided on both the bottom and the sidewall to accommodate the rolling element 53, and this embodiment is not limited to this. It can be understood that when the rolling element 53 is placed in the accommodating groove 54, part of the structure of the rolling element 53 protrudes from the accommodating groove 54, that is, part of the structure is located in the support groove 52, thereby achieving the abutment between the rolling element 53 and the side wall of the LCP braided yarn fiber bundle guide disk 200.

[0039] On the other hand, the utility model also provides a braiding machine, including a transmission device of a braiding machine as described above, and also including a braiding yarn frame 100 and an LCP braiding yarn fiber bundle guide disk 200; the braiding yarn frame 100 is used to fix the braiding yarn wheel wound with the braiding yarn fiber bundle; the LCP braiding yarn fiber bundle guide disk 200 is used to guide the braiding yarn fiber bundle; the braiding yarn frame 100 and the LCP braiding yarn fiber bundle guide disk 200 are connected by multiple support columns; the transmission device is used to drive the braiding yarn frame 100 to rotate.

[0040] The braiding machine also includes a core yarn holder 300, mounted on the base 1. The core yarn holder 300 is used to secure a core yarn wheel wound with a core yarn fiber bundle. A fifth through-hole for the core yarn fiber bundle to pass through is provided on the first rotating shaft 21 and the LCP braiding yarn fiber bundle guide disc 200. Glass fibers pass through the fifth through-hole and connect to the twisting guide module, enabling the braiding machine to weave a fiber rope.

[0041] 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.

[0042] To sum up, the utility model limits the weaving yarn frame 100 by providing at least three second limiting members 42 on the mounting bracket 3 and a first limiting member 41 on the weaving yarn frame 100, through the first protrusion 411, the second protrusion 412 and the first limiting gap 413 formed between the first protrusion 411 and the second protrusion 412 provided on the first limiting member 41, and the third protrusion 421 and the fourth protrusion 422 provided on the second limiting member 42 and the second limiting gap 423 formed between the third protrusion 421 and the third protrusion 421. On the one hand, it ensures that the central axis of the weaving yarn frame 100 will not tilt relative to the horizontal plane, and ensures that the rotational power of the driving member 22 can be effectively transmitted to the weaving yarn frame 100, thereby ensuring the stability of the operation of the weaving machine. On the other hand, the cooperation of the first protrusion 411 and the second limiting gap 423 and the cooperation of the fourth protrusion 422 and the first limiting gap 413 can also prevent the weaving yarn frame 100 from moving up and down and left and right relative to the horizontal plane. Therefore, the utility model effectively overcomes various shortcomings of the prior art and has high industrial utilization value.

[0043] 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. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
