Description

Technical Field

[0001] This utility model relates to the field of wire flattening technology, specifically to a braiding device that can flatten braided wire. Background Technology

[0002] In the traditional production process of braided yarn, old-fashioned braiding machines, lacking an integrated flattening device, usually require a two-stage production process. First, the initial shaping of the braided yarn is completed, and then the yarn is flattened by manual labor or auxiliary equipment.

[0003] However, this segmented production process has significant technical drawbacks. Due to manual operation, it is difficult to maintain a uniform flattening effect, resulting in large fluctuations in the key parameters of the braided yarn, which affects the quality stability of the product. Furthermore, the reliance on manual operation to complete the conversion between rewinding and flattening processes increases the labor intensity of workers. In addition, the low production efficiency and increased scrap rate lead to high production costs. Moreover, during the secondary flattening process, mechanical external force can easily cause irreversible damage to the braided yarn structure, which can easily reduce the mechanical strength and service life of the product. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a braiding equipment that can complete the rewinding and flattening process without relying on manual operation, thereby improving the flattening quality of braided yarn and reducing production costs.

[0005] To solve the above problems, this utility model provides the following technical solution:

[0007] A braiding machine is used to twist and combine wires to form braided yarn;

[0008] A spool is used to take in the braided yarn;

[0009] A flattening mechanism is provided between the braiding machine and the rubber shaft. When the braided yarn passes through the flattening mechanism from the braiding machine, it is flattened by the flattening mechanism and wound around the rubber shaft.

[0010] In one embodiment, the flattening mechanism includes a flat wheel and a flattening wheel, the flattening wheel being in contact with the flat wheel, and the braiding thread passing between the flat wheel and the flattening wheel.

[0012] In one embodiment, the flattening mechanism further includes a main body and a support shaft, the support shaft being mounted on the main body, and the central part of the planar wheel being sleeved through the support shaft and rotatable around the support shaft.

[0013] In one embodiment, the flattening mechanism further includes a robotic arm mounted on the main body and an elastic element mounted on the robotic arm. The flattening wheel is mounted on the robotic arm, and the elastic element adjusts the pressure applied by the flattening wheel to the planar wheel by adjusting its mounting position on the robotic arm.

[0014] In one embodiment, the robotic arm includes a first arm and a second arm, the first arm being mounted on the main body, the second arm being connected to the first arm, the elastic element being sleeved on the first arm, and the flattening wheel being mounted on the end of the second arm away from the first arm.

[0015] In one embodiment, the first arm passes through the second arm and is rotatably connected to the second arm. The elastic element is provided with a limiting post at one end near the second arm. The second arm is provided with a plurality of limiting holes corresponding to the limiting posts. The limiting posts are plugged into and pulled into each of the limiting holes.

[0016] In one embodiment, a guide wheel is further included, which is disposed between the flattening mechanism and the rubber shaft, and / or the guide wheel is disposed between the braiding machine and the flattening mechanism.

[0017] In one embodiment, the number of guide wheels ranges from 1 to 3.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] Please refer to Figure 1-4 As shown, this embodiment provides a braiding device 10 for flattening braided yarn 200, which includes: a braiding machine 100, a rubber roller 110, and a flattening mechanism 120 disposed between the braiding machine 100 and the rubber roller 110; wherein, the braiding machine 100 is used to three-dimensionally twist multiple strands of metal or non-metal wires according to preset braiding parameters to form an initial braided yarn 200 with a regular mesh structure; the braided yarn 200 is flattened by the flattening mechanism 120 when it passes from the braiding machine 100, and by winding the braided yarn 200 around the rubber roller 110 in advance, the braided yarn 200 is wound up by the rotation of the rubber roller 110, thereby realizing the constant tension winding of the flattened braided yarn 200.

[0029] According to the above scheme, this embodiment realizes a continuous production process of braiding, flattening and winding by setting the flattening mechanism 120 between the braiding machine 100 and the rubber shaft 110. This eliminates the downtime and rewinding links in the traditional step-by-step process, thereby improving the production and flattening efficiency of the braided yarn 200, ensuring the uniformity of the thickness and density of the braided yarn 200, significantly improving the mechanical strength and service life of the product, and this design avoids quality fluctuations caused by manual intervention and reduces the operating intensity of operators.

[0030] Please refer to Figure 1-4 As shown, preferably, the flattening mechanism 120 includes a flat wheel 122 and a flattening wheel 123. The flattening wheel 123 contacts the flat wheel 122, and the braided thread 200 passes between the flat wheel 122 and the flattening wheel 123. Optionally, the flat wheel 122 is made of high-carbon alloy steel and its surface is hardened to have excellent wear resistance. The flattening wheel 123 and the flat wheel 122 form a paired structure, and its working surface is ground to ensure the flatness of the contact surface with the flat wheel 122. During the transmission process, the braided thread 200 passes through the pressing point between the two wheels to achieve uniform flattening.

[0031] like Figure 1 As shown, according to the above scheme, the flat wheel 122 is provided with a pressing groove 121a, which is used for the braided thread 200 to pass through. At least a part of the flattening wheel 123 is in close contact with the bottom surface of the pressing groove 121a. It can be understood that both the flattening wheel 123 and the flat wheel 122 are cylindrical structures, and the outer surface of the pressing wheel is arc-shaped, so that a part of the outer surface of the pressing wheel always remains in close contact with a part of the outer surface of the flat wheel 122 during rotation. In addition, the inner surface of the pressing groove 121a is polished to reduce the coefficient of friction between the bottom surface of the pressing groove 121a and the pressing wheel, thereby avoiding wear of the braided thread 200 during the pressing process.

[0032] Please refer to Figure 1 and Figure 3 As shown, preferably, the flattening mechanism 120 also includes a main body 121 and a support shaft 124. The main body 121 is made of cast iron and has high rigidity and shock absorption performance. The support shaft 124 is fixedly installed on the main body 121. The flat wheel 122 has a through hole in the center. By passing the through hole in the center of the flat wheel 122 through the support shaft 124, the flat wheel 122 can rotate around the support shaft 124. The design of fixing the support shaft 124 to the main body 121 improves the rigidity of the support shaft 124, thereby further improving the support effect of the support shaft 124 on the flat wheel 122 when rotating and ensuring smooth rotation.

[0033] like Figure 1As shown, preferably, the flattening mechanism 120 further includes a robotic arm 125 mounted on the main body 121 and an elastic element 126 mounted on the robotic arm 125. A flattening wheel 123 is mounted on the robotic arm 125, and the elastic element 126 adjusts the pressure applied by the flattening wheel 123 to the flat wheel 122 by adjusting its mounting position on the robotic arm 125. It can be understood that during use, the user can adjust the flatness of the braided yarn 200 to be flattened according to the needs of different types of braided yarn 200, thereby meeting the needs of different users for braided yarn 200 with different flatness. The principle is: by adjusting the elastic element 126 on the robotic arm 125... The mounting position on the upper part causes the elastic force of the elastic element 126 on the robotic arm 125 to change, which in turn causes the elastic force of the robotic arm 125 on the flattening wheel 123 mounted thereon to change. Since part of the flattening wheel 123 is in contact with the bottom surface of the pressing groove 121a of the flat wheel 122, when the elastic force of the robotic arm 125 on the flattening wheel 123 changes, the pressure between the flattening wheel 123 and the bottom surface of the pressing groove 121a of the flat wheel 122 changes accordingly. This causes the force on the braided thread 200 passing through the contact surface between the flattening wheel 123 and the flat wheel 122 to change the degree of flattening of the braided thread 200.

[0034] Optionally, the elastic element 126 may be a pre-compressed helical spring.

[0035] Please refer to Figure 1-3 As shown, preferably, the robotic arm 125 is designed as a hierarchical structure, including a first robotic arm 1251 and a second robotic arm 1252. The first robotic arm 1251 is mounted on the main body 121 and serves as a basic support arm, fixed to the main body 121 by bolts to form a stable support foundation. The second robotic arm 1252 is movably connected to the first robotic arm 1251 and serves as a pressure transmission component. An elastic element 126 is sleeved on the first robotic arm 1251, and a flattening wheel 123 is mounted on the end of the second robotic arm 1252 away from the first robotic arm 1251. This cantilever design can amplify the sensitivity of pressure adjustment. Furthermore, one end of the spring is fixed at the reference position of the first robotic arm 1251, and the other end acts on the lever arm point of the second robotic arm 1252. When it is necessary to increase the flattening force, the compression of the spring can be increased, so that the downward force of the second robotic arm 1252 can be increased. When it is necessary to reduce the pressure, the compression of the spring can be released to reduce the downward pressure of the second robotic arm 1252.

[0036] Please refer to Figure 1-3As shown, preferably, the first arm 1251 passes through the second arm 1252 and is rotatably connected to the second arm 1252. The elastic member 126 is provided with a limiting post 1261 at one end near the second arm 1252. The second arm 1252 is provided with a plurality of limiting holes 1252a corresponding to the limiting post 1261. That is, the limiting post 1261 at the end of the elastic member 126 and the plurality of limiting holes 1252a on the second arm 1252 form an adjustable locking structure. The limiting post 1261 is plugged into and pulled into each limiting hole 1252a.

[0037] Preferably, the number of limiting holes 1252a is set between 2 and 4.

[0038] like Figure 2-3 As shown, according to the above scheme, the limiting post 1261 is made of high-strength alloy steel, which has strong rigidity and thus good supporting force. The limiting holes 1252a are arranged at equal intervals on the second arm 1252, and each hole corresponds to a different spring compression, thus forming a graded pressure adjustment structure. Optionally, this embodiment sets three limiting holes 1252a. It can be understood that the working principle of this pressure adjustment is as follows: when it is necessary to increase the flattening force, simply insert the limiting post 1261 into the limiting hole 1252a away from the first arm 1251. This will increase the effective compression of the spring, thereby enhancing the downward pressure of the second arm 1252. Conversely, inserting it into the limiting hole 1252a close to the first arm 1251 will reduce the flattening force. The pressure difference corresponding to each hole is accurately calculated to ensure that each adjustment brings a significant change in force. This mechanical adjustment method is not only simple and reliable to operate, but also avoids the use of complex electronic control systems, greatly reducing the maintenance cost of the equipment.

[0039] like Figure 4 As shown, preferably, it also includes a guide wheel 130, which is disposed between the flattening mechanism 120 and the adhesive shaft 110, and / or the guide wheel 130 is disposed between the braiding machine 100 and the flattening mechanism 120; optionally, in this embodiment, the guide wheel 130 is disposed between the flattening mechanism 120 and the adhesive shaft 110, which is used to guide the braided thread 200 that passes through after being flattened by the flattening mechanism 120. The flattened braided thread 200 is guided by the guide groove on the guide wheel 130 and has a certain tension effect so that the product quality of the flattened braided thread 200 is maintained at a high level during the winding process of the adhesive shaft 110.

[0040] Preferably, the number of guide wheels is between 1 and 3; in this embodiment, 2 guide wheels are used.

[0041] In summary, this utility model provides a braiding device that can flatten braided yarn. By placing the flattening mechanism between the braiding machine and the rubber shaft, a continuous production process of braiding, flattening, and winding is realized, eliminating the downtime and yarn rewinding steps in the traditional step-by-step process. This improves the production and flattening efficiency of braided yarn, ensures the uniformity of braided yarn thickness and density, significantly improves the mechanical strength and service life of the product, and avoids quality fluctuations caused by manual intervention, reducing the operational intensity of operators.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
