Description

Technical Field

[0001] This utility model relates to the technical field of hybrid cable processing equipment, specifically to a braiding device for hybrid signal cables. Background Technology

[0002] In the field of modern communication and electronic equipment, mixed-signal cables are increasingly widely used. Mixed-signal cables typically require good signal transmission performance and mechanical properties to ensure the normal operation of equipment. In the manufacturing process of mixed-signal cables, the braiding process is a crucial step, significantly impacting the cable's quality and performance.

[0003] Existing hybrid signal cable braiding devices present numerous inconveniences in adjusting cable tension during the braiding process. Tension is one of the key factors affecting the quality and performance of cable braiding. Insufficient tension may cause the cable to slip or loosen during braiding, thus affecting the cable's structural stability and signal transmission quality; while excessive tension may damage the cable's insulation layer, shielding layer, and other protective structures, shortening the cable's lifespan. This is especially true in the braiding of hybrid signal cables, where the uniformity and stability of tension are even more critical due to the multiple signal transmission lines within the cable. Existing braiding devices often struggle to ensure consistent tension across all cables during the braiding process when weaving complex structures, resulting in unstable braiding quality and impacting the overall performance of the cable.

[0004] Chinese utility model patent (publication number CN219626398U) discloses a cable braiding device, which uses a dual-axis cylinder connected to an external air supply device for timed air supply. After a period of braiding, the braiding mechanism is stopped, and the dual-axis cylinder pushes the moving seat to move, which in turn drives the take-up roller to move. The guide ring guides the movement, which facilitates the stability of the braided tape during braiding. When the braided layer of the cable is loosened, the guide ring presses the braided tape against the side wall of the braiding mechanism. Since the cable core is not exposed, the braided tape woven around the cable core is loosened, avoiding tightness.

[0005] However, in practical use, the aforementioned existing technology makes it inconvenient to adjust the tension of the cable during the braiding process, resulting in the inability to adjust the tension in real time according to the actual condition of the cable or process requirements. This not only leads to quality problems such as inconsistent tightness and uneven structure in the braided cable, but also increases the defect rate and production costs in the long-term production process.

Detailed Implementation

[0027] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0028] See Figures 1-9 As shown, the device includes a housing 1, a swing arm 2 mounted on the housing 1, a cable rotating winding roller 3 mounted on the swing arm 2, and a rotation drive unit 4 mounted on the housing 1 for driving the swing arm 2 to rotate. The braiding device also includes an adjustment mechanism 5 and a yarn management mechanism 6. The adjustment mechanism 5 is mounted on the swing arm 2. The adjustment mechanism 5 includes a pair of first overlapping rollers 51 capable of overlapping the cables on the cable rotating winding roller 3, a connecting plate 52 mounted on the swing arm 2 for mounting the pair of first overlapping rollers 51, and a movable abutment block 53 capable of driving the pair of first overlapping rollers 51 and the connecting plate 52 to move closer or further apart. The yarn management mechanism 6 is located on the top of the housing 1 and on one side of the adjustment mechanism 5.

[0029] The housing 1 is also equipped with a traction and winding mechanism 7 connected to the cable on the cable rotating winding roller 3. The traction and winding mechanism 7 is a cable take-up roller, which is an existing device. The cable is sequentially wound around the cable rotating winding roller 3 and the first overlapping roller 51, then passed through the cable management mechanism 6, and finally fixed on the cable take-up roller. At this point, the initial work of cable braiding is completed. The first overlapping roller 51 is divided into upper and lower sections. The cable on the cable rotating winding roller 3 can be manually passed between the upper and lower first overlapping rollers 51. When the cable take-up roller rotates and pulls the cable, it can effectively reduce the contact friction of the cable during the braiding process. The rotary drive unit 4 includes a rotary driver 41 mounted on the housing 1. The housing 1 is also equipped with a support roller 42, and the support roller 42 is equipped with a transmission belt 43 connected to the output end of the rotary driver 41. When the rotary driver 41 is started, the rotational force is transmitted to the support roller 42 through the transmission belt 43. The support roller 42 is fixedly connected to the swing arm 2, so that when the support roller 42 rotates, it can drive the swing arm 2 to rotate synchronously. When the swing arm 2 rotates, the cable can be braided. In order to adjust according to the diameter of different cables, the tension between the first overlapping roller 51 and the cable can be adjusted by setting the adjustment mechanism 5, thereby ensuring the smooth progress of the braiding work and the stability of the braiding quality.

[0030] See Figure 4 and Figure 5 As shown, the adjustment mechanism 5 also includes a telescopic cylinder 54 and a guide rod 55; the telescopic cylinder 54 is mounted on the swing arm 2, and the output end of the telescopic cylinder 54 is fixedly connected to the movable abutment block 53; a pair of symmetrically arranged limiting grooves 21 are provided on the swing arm 2; the guide rod 55 is mounted in the limiting groove 21, and there is a clearance fit between the guide rod 55 and the connecting plate 52.

[0031] When the connecting plate 52 and the first overlapping roller 51 need to move closer together, the telescopic cylinder 54 first drives the movable abutment block 53 to slide horizontally in a straight line. The movable abutment block 53 has a trapezoidal structure. This allows the connecting plate 52 to slide along the trapezoidal surface of the movable abutment block 53 as it moves. Furthermore, during this sliding motion along the trapezoidal surface, the guide rod 55 on the swing arm 2 provides a constraint, ensuring a stable relative approach and guaranteeing the stability and accuracy of the adjusting mechanism 5 when adjusting the tension of the cable to be wound on the cable rotating winding roller 3.

[0032] See Figure 6 and Figure 7As shown, the adjustment mechanism 5 also includes a limiting block 56 and rolling columns 57; the movable abutment block 53 has two symmetrically arranged rolling grooves 531, which slide in cooperation with the connecting plate 52; the limiting block 56 has a pair and is symmetrically arranged on the movable abutment block 53; the limiting block 56 has a slot 561; the rolling columns 57 have multiple ones and are equidistantly rotatably arranged on the connecting plate 52, and the rolling columns 57 slide within the slot 561.

[0033] During the process of the connecting plate 52 sliding along the trapezoidal surface of the movable abutment block 53, the multiple rolling columns 57 rotatably arranged on the connecting plate 52 will contact the slots 561 opened on the limiting block 56 and generate rotational sliding, making the connecting plate 52 more stable when sliding along the trapezoidal surface and reducing the friction generated during sliding.

[0034] See Figure 8 As shown, the adjustment mechanism 5 also includes a fixing plate 58; the fixing plate 58 has a pair of symmetrically arranged on the movable abutment block 53; the connecting plate 52 is provided with a relief groove 521, when the movable abutment block 53 slides in a horizontal straight direction, the connecting plate 52 is in a relatively close horizontal straight direction sliding state, and the fixing plate 58 can slide in the relief groove 521.

[0035] When the connecting plate 52 moves closer to the moving abutment block 53, it can continue until the clearance groove 521 on the connecting plate 52 abuts against the fixed plate 58 on the moving abutment block 53. When they abut, the moving abutment block 53 stops moving. This is the maximum distance between the connecting plate 52 and the first overlapping roller 51, ensuring the safety and stability of the adjustment mechanism 5 during the adjustment process.

[0036] See Figure 9 As shown, the cable management mechanism 6 includes a mounting frame 61, a first cable management roller 62, a second cable management roller 63, and a lifting cylinder 64; the mounting frame 61 is mounted on the housing 1 and is located near the side of the swing arm 2; the first cable management roller and the second cable management roller 63 are respectively rotatably mounted on the mounting frame 61; the lifting cylinder 64 is mounted on the mounting frame 61.

[0037] The cable passes between the first limiting cable guide roller 62 and the second limiting cable guide roller 63, so that when the swing arm 2 rotates to braid the cable, the cable can be stably limited by the first limiting cable guide roller 62 and the second limiting cable guide roller 63, limiting the positional deviation of the cable during the braiding process, and avoiding braiding defects or incompleteness due to unstable cable position.

[0038] See Figure 9As shown, the cable management mechanism 6 also includes an ejector plate 65 and a limiting plate 66; the ejector plate 65 is vertically and slidably mounted on the mounting frame 61, and the ejector plate 65 is fixedly connected to the output end of the lifting cylinder 64; the limiting plate 66 is mounted on the ejector plate 65, and the limiting plate 66 is rotatably connected to the first cable management roller 62.

[0039] When the cable diameter is large and the distance between the first limiting cable guide roller 62 and the second limiting cable guide roller 63 needs to be adjusted, the lifting cylinder 64 is first activated, driving the ejector plate 65, which is clearance-fitted with the mounting frame 61, to rise vertically along the mounting frame 61. As the ejector plate 65 rises vertically, one end of the limiting plate 66 is fixedly connected to the ejector plate 65, and the other end of the limiting plate 66 is connected to the first limiting cable guide roller 62. This allows the ejector plate 65 to drive the first limiting cable guide roller 62 to rise synchronously in the vertical direction through the connected limiting plate 66, thereby adjusting the position of the first limiting cable guide roller 62. By adjusting the distance between the first limiting cable guide roller 62 and the second limiting cable guide roller 63, cables of different diameters can be restricted and braided.

[0040] During operation, the cable is first wound around the cable rotating winding roller 3 and the two upper and lower first overlapping rollers 51, then passed through the cable management mechanism 6, and finally fixed on the cable take-up roller, thus completing the initial setup for cable braiding. The cable on the cable rotating winding roller 3 can be manually passed between the upper and lower first overlapping rollers 51. When the cable take-up roller rotates and pulls the cable, the first overlapping rollers 51 effectively reduce the contact friction of the cable during the braiding process. The rotary driver 41 transmits rotational force to the support roller 42 through the transmission belt 43. The support roller 42 is fixedly connected to the swing arm 2, so the rotation of the support roller 42 will drive the swing arm 2 to rotate synchronously, thereby performing the cable braiding work. When it is necessary to adjust the cable tension, the telescopic cylinder 54 drives the trapezoidal movable abutment block 53 to slide horizontally in a straight line. The trapezoidal structure of the movable abutment block 53 allows the connecting plate 52 to slide stably along its trapezoidal surface during the sliding process, and is restricted by the guide rod 55 on the swing arm 2, ensuring the stability and accuracy of the sliding. Multiple rolling columns 57 rotatably mounted on the connecting plate 52 contact the slots 561 on the limiting block 56 and rotate and slide, further enhancing the stability of the sliding and reducing friction. When the connecting plate 52 slides to the point where the clearance groove 521 on it abuts against the fixed plate 58 on the movable abutment block 53, the sliding stops. At this time, the connecting plate 52 and the first overlapping roller 51 reach their maximum relative distance, ensuring safety and stability during the adjustment process. During the braiding process, the cable passes between the first limiting wire guiding roller 62 and the second limiting wire guiding roller 63. These two wire guiding rollers stably limit the cable's position, preventing the cable from shifting during the braiding process, thereby avoiding braiding defects or incompleteness. When the cable diameter is large and the distance between the two wire guiding rollers needs to be adjusted, the lifting cylinder 64 is activated, driving the ejector plate 65, which is clearance-fitted with the mounting frame 61, to rise vertically along the mounting frame 61. Since one end of the limiting plate 66 is fixedly connected to the ejector plate 65 and the other end is connected to the first limiting wire guiding roller 62, the rise of the ejector plate 65 will drive the first limiting wire guiding roller 62 to rise synchronously through the limiting plate 66, thereby realizing the adjustment of the distance between the two wire guiding rollers to adapt to the braiding requirements of cables of different diameters.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
