Description

Technical Field

[0001] This utility model relates to the field of winding machine technology, and more particularly to a winding machine support arm structure. Background Technology

[0002] In the processing of industrial materials such as sheet metal, plastic film, and textile fabrics, the winding machine is the core equipment for winding and forming materials. The winding machine is a key piece of equipment in industrial production used to wind continuously conveyed strip or sheet materials into regular coils. It is widely used in metallurgy, papermaking, plastics, textiles, and many other industries. It is a core device that ensures continuous operation of the production line and improves the convenience of subsequent material processing. Its overall functionality depends on precise structural design and collaborative working mechanisms. The support arm structure, as a key component of the winding machine, directly affects the stability of the winding operation and the quality of the finished product.

[0003] While existing coiler support arm structures provide basic support for the coiling operation, they suffer from several drawbacks. Firstly, the adjustment of the support arm's angle and position often relies on manual operation or a single hydraulic / pneumatic drive. This makes it difficult to control adjustment precision, and unilateral force can easily lead to structural imbalance. Long-term use can result in tilting, jamming, and accelerated wear of connecting components, ultimately affecting the flatness of the material during coiling and increasing the defect rate. Secondly, the winding positioning components are often fixed structures or have cumbersome adjustment methods, failing to flexibly adjust the positioning position according to materials of different widths and thicknesses. This results in poor guiding and limiting effects on the coiled material, easily leading to material misalignment and edge friction damage. Furthermore, jamming of the positioning components increases equipment maintenance frequency and costs, resulting in low overall ease of use and economy. Therefore, a new coiler support arm structure is proposed to address these issues. Utility Model Content

[0004] To address the aforementioned technical problems, a winding machine support arm structure is provided. This invention uses an electric lifting rod to drive a limiting block to adjust the support arm angle, employs lubricating balls to reduce friction, and utilizes an adjusting screw and guide rod to achieve precise material positioning, ensuring uniform force distribution and stable winding.

[0005] To achieve the above objectives, this utility model provides a winding machine support arm structure, comprising: a fixed frame, a connecting seat fixedly connected to the inner surface of the fixed frame, a support arm rotatably connected to the inner side of the connecting seat, a winding positioning component provided on the surface of the support arm, and an adjusting support component provided between the support arm and the fixed frame; The adjustable support assembly includes a limiting groove and a lubrication groove. The limiting groove is formed on the outer surface of the support arm, and a limiting block is slidably connected to the inner side of the limiting groove. An electric lifting rod is fixedly connected between the outer wall of the limiting block and the inner wall of the fixed frame. The lubrication groove is formed on the upper surface of the support arm, and a ball bearing is slidably connected inside the lubrication groove.

[0006] Furthermore, there are two electric lifting rods, which are mirror images of each other along the central axis of the support arm.

[0007] Furthermore, the lubrication groove has a C-shaped slot structure, and multiple balls are arranged in a ring along the inside of the lubrication groove.

[0008] Furthermore, the winding positioning component includes a through hole and a screw hole, both of which are formed on the outer surface of the support arm.

[0009] Furthermore, a guide rod is fitted to the inner side of the through hole, and an adjusting screw is threaded to the inner side of the screw hole.

[0010] Furthermore, a positioning baffle is fixedly connected to the rear end of the guide rod, and a bearing seat is fixedly connected to the outer surface of the positioning baffle.

[0011] Furthermore, the rear end of the adjusting screw is rotatably connected to the inside of the bearing housing.

[0012] Furthermore, there are two connecting seats and two supporting arms, and the two connecting seats and two supporting arms are mirror images of each other along the central axis of the fixed frame.

[0013] By adopting the above technical solution, this utility model has the following advantages compared with the prior art: 1. The present invention provides a winding machine support arm structure. By adjusting the support assembly, two mirror-arranged electric lifting rods extend and retract, driving the limiting block to slide in the limiting groove, pushing the support arm to rotate around the connecting seat. The ball bearings in the lubrication groove reduce friction, thus achieving precise positioning of the support arm and stable support of the winding machine shaft, ensuring symmetrical and uniform force distribution of the structure, avoiding tilting, jamming and component damage, extending service life, and improving winding stability and material flatness.

[0014] 2. The winding machine support arm structure provided by this utility model, through the winding positioning component, allows the operator to rotate the adjusting screw connected to the screw hole threadedly. Its rear end drives the positioning baffle to move through the bearing seat, and the guide rod slides and guides in the through hole. In this way, the positioning baffle can be precisely adjusted, which can position and guide the winding material, prevent deviation, reduce material friction damage, ensure the stability and service life of the component, and improve the quality of the winding product.

[0025] Reference Figures 1 to 4This utility model provides an embodiment of a coiler support arm structure, including a fixed frame 1. The fixed frame 1 serves as the basic load-bearing component of the entire support arm structure, providing a stable installation platform for subsequent connected components. Its material is typically high-strength steel to ensure sufficient load-bearing capacity and structural stability. A connecting seat 2 is fixedly connected to the inner surface of the fixed frame 1. The connecting seat 2 is tightly fixed to the fixed frame 1 by welding or bolting, mainly serving to connect the fixed frame 1 and the support arm 3, ensuring the stability and reliability of the support arm 3 during rotation. The support arm 3 is rotatably connected to the inner side of the connecting seat 2. Two connecting seats 2 and two support arms 3 are provided. The two connecting seats 2 and two support arms 3 ensure the stability and reliability of the entire support structure. More symmetrical and with more even force distribution, this design effectively improves stability during the winding process and prevents structural deformation or damage caused by excessive force on one side. Both connecting seats 2 and support arms 3 are mirror images of each other along the central axis of the fixed frame 1. This mirror image arrangement further ensures structural symmetry, allowing the two support arms 3 to move synchronously during operation. This ensures the flatness and consistency of the wound material and reduces the impact of uneven force distribution on winding quality. An adjustable support assembly 5 is installed between the support arm 3 and the fixed frame 1. This assembly is mainly used to adjust the angle and position of the support arm 3 and provide stable support, ensuring that the support arm 3 remains in a preset position during operation, withstands various forces during the winding process, and improves the overall support arm structure. To ensure the stability and reliability of the structure, the adjusting support assembly 5 includes a limiting groove 51 and a lubrication groove 54. The limiting groove 51 and lubrication groove 54 are important structures of the adjusting support assembly 5, respectively limiting the movement range of the limiting block 52 and reducing the rotational friction of the support arm 3. They work together to ensure the normal operation of the adjusting support assembly 5. The limiting groove 51 is located on the outer surface of the support arm 3. This allows it to cooperate with the limiting block 52 to limit the rotation angle of the support arm 3, preventing it from exceeding its working range due to excessive rotation and avoiding collisions with other components or structural damage. The limiting block 52 is slidably connected to the inner side of the limiting groove 51, allowing the limiting block 52 to slide within the limiting groove 51. The support arm 3 is fixedly connected to the electric lifting rod 53. The extension and retraction of the electric lifting rod 53 moves the limiting block 52, thereby driving the support arm 3 to rotate. Its sliding fit has high precision, ensuring the smooth rotation of the support arm 3. The electric lifting rod 53 is fixedly connected between the outer wall of the limiting block 52 and the inner wall of the fixed frame 1. The electric lifting rod 53 is the power source for adjusting the support assembly 5. It uses an electric drive method, enabling precise extension and retraction control, thereby accurately adjusting the angle and position of the support arm 3. It has advantages such as fast response speed, high control precision, and stable operation, meeting the high-precision requirements of the winding machine for adjusting the position of the support arm. Two electric lifting rods 53 are provided, which can provide a more uniform driving force and support force to the support arm 3.To prevent tilting or jamming of the support arm 3 due to uneven force distribution caused by unilateral drive, and to ensure the stability and smoothness of the support arm 3 during adjustment, two electric lifting rods 53 are mirror-mounted along the central axis of the support arm 3. These mirror-mounted electric lifting rods 53 can extend and retract synchronously, ensuring that the support arm 3 remains balanced during rotation, preventing offset or wobbling, and further improving the working stability and reliability of the entire support structure. A lubrication groove 54 is located on the upper surface of the support arm 3. This location facilitates the addition of lubricant and allows the balls 55 to roll better within the lubrication groove, providing lubrication and reducing frictional resistance between the winding machine shaft and the support arm 3 during rotation. The lubrication groove 54 has a C-shaped slot structure, which effectively limits the movement of the balls 55, preventing them from slipping. During the rolling process, the balls 55 detach from the lubrication groove 54, ensuring that they roll along a preset trajectory within the groove 54, guaranteeing uniform lubrication. The lubrication groove 54 contains rolling balls 55. The rolling of these balls converts the sliding friction between the support arm 3 and other contact components into rolling friction, significantly reducing frictional resistance, minimizing component wear, and extending the service life of the support arm structure. This also makes the support arm 3 more flexible and smooth. Furthermore, multiple balls 55 are arranged in a ring along the inside of the lubrication groove 54. This ring-shaped distribution ensures that the support arm 3 experiences more even force and more comprehensive lubrication during the rotation of the winding machine shaft, preventing increased friction or component damage due to localized lack of lubrication. This further enhances the stability and flexibility of the support arm 3 when supporting the winding machine shaft.

[0026] Reference Figures 1 to 4The surface of the support arm 3 is provided with a winding positioning component 4. The winding positioning component 4 is a key component to ensure accurate winding of the material. It can position and guide the material during the winding process, prevent the material from shifting during winding, and improve the quality of the wound product. The winding positioning component 4 includes a through hole 41 and a screw hole 42. The through hole 41 and the screw hole 42 are important components of the winding positioning component 4, providing installation positions for the guide rod 43 and the adjusting screw 44, respectively. Their opening positions and dimensions are precisely calculated to ensure the fitting accuracy between the components. Both the through hole 41 and the screw hole 42 are provided with... On the outer surface of the support arm 3, through holes 41 and screw holes 42 are formed to facilitate the installation, debugging, and maintenance of the winding positioning assembly 4 by the staff, while also ensuring the stability of each component during operation. A guide rod 43 is fitted to the inner side of the through hole 41, and the guide rod 43 fits tightly with the through hole 41, allowing it to slide back and forth within the through hole 41. This provides guidance for the movement of the positioning baffle 45, ensuring that the positioning baffle 45 always moves in the preset direction during adjustment, thus improving positioning accuracy. An adjusting screw 44 is threaded to the inner side of the screw hole 42. 4. The guide rod 43 is connected to the screw hole 42 via a thread. Operators can rotate the adjusting screw 44 to move the positioning baffle 45, thereby achieving precise adjustment of the positioning position. The threaded connection is self-locking, ensuring stable and reliable positioning after adjustment and preventing loosening. The rear end of the guide rod 43 is fixedly connected to the positioning baffle 45, which directly contacts the wound material. The positioning baffle 45 positions and limits the material through its own position adjustment. Its surface is usually coated with a wear-resistant or anti-slip coating to reduce friction damage to the material while ensuring effective positioning. The outer surface of the positioning baffle 45... A bearing seat 46 is fixedly connected to the surface, and a bearing is installed inside the bearing seat 46 to support the rotation of the adjusting screw 44, reduce the frictional resistance when the adjusting screw 44 rotates, and make the adjustment process easier and smoother. At the same time, it can also protect the adjusting screw 44 and the positioning baffle 45 and extend their service life. The rear end of the adjusting screw 44 is rotatably connected to the inside of the bearing seat 46. This rotatable connection means that when the adjusting screw 44 rotates, it can push the positioning baffle 45 to move, but it will not drive the positioning baffle 45 to rotate itself, ensuring that the positioning baffle 45 always maintains the correct working posture and guarantees the positioning effect.

[0027] Working principle: During the operation of the coiler support arm structure, the fixed frame 1, which serves as the basic load-bearing component, is used as the overall support foundation. It is made of high-strength steel to ensure sufficient load-bearing capacity and provide a stable installation platform for subsequent components. The connecting seat 2, which is fixedly connected to the inner surface of the fixed frame 1, is a key component connecting the fixed frame 1 and the support arm 3, enabling the rotational connection of the support arm 3. The two connecting seats 2 and the support arm 3 are mirror images of each other along the central axis of the fixed frame 1 to ensure structural symmetry and uniform stress, laying the foundation for the stable operation of subsequent coiling operations. When the angle and position of the support arm 3 need to be adjusted to adapt to the winding requirements, the adjustment support assembly 5 begins to function: the two mirror-mounted electric lifting rods 53, which serve as the power source, are activated. They are respectively connected to the outer wall of the limiting block 52 and the inner wall of the fixed frame 1. Through precise extension and retraction, they drive the limiting block 52, which is fixed to it, to slide smoothly in the limiting groove 51 on the outer surface of the support arm 3. At the same time, the limiting groove 51 limits the movement range of the limiting block 52, preventing the support arm 3 from rotating too much and exceeding the working range. During the process of the support arm 3 rotating with the limiting block 52, multiple balls 55 distributed in a ring inside the lubrication groove 54 with a C-shaped groove structure on the upper surface of the support arm 3 convert the sliding friction between the support arm 3 and the contact parts into rolling friction, greatly reducing frictional resistance. This ensures that the rotation of the support arm 3 and the winding machine shaft is flexible and smooth, reduces component wear, and extends service life. Ultimately, the support arm 3 is precisely adjusted to the preset working position and maintains stable support, bearing various forces during the winding process. When the support arm 3 is adjusted into position and enters the winding operation stage, the winding positioning component 4 on the surface of the support arm 3 begins to position and guide the winding material: the operator rotates the adjusting screw 44, which is threaded to the screw hole 42 on the outer surface of the support arm 3. Utilizing the self-locking and precise adjustment characteristics of the threaded connection, the operator pushes the positioning baffle 45, which is rotatably connected to the rear end of the adjusting screw 44 through the bearing seat 46, to move. At the same time, the guide rod 43, which is fixedly connected to the positioning baffle 45, slides tightly against the through hole 41 of the support arm 3, providing stable guidance for the positioning baffle 45 and ensuring that it moves in the preset direction. Ultimately, the positioning baffle 45 makes precise contact with the winding material, achieving positioning and limiting of the material, preventing deviation during the winding process, ensuring the flatness and quality of the wound product, and completing the support and positioning work of the entire winding operation.
