Description

Technical Field

[0001] This invention relates to the field of dry-type transformer production equipment technology, and in particular to a dry-type transformer coil winding device. Background Technology

[0002] Dry-type transformers are widely used in power transmission and distribution. Whether it is a substation in an urban power grid, a power supply system in an industrial park, or a power distribution facility in a residential community, they all rely on their stable operation. As the core component of a dry-type transformer that realizes electromagnetic energy conversion, the winding quality of the coil directly affects the transformer's performance. Among them, the mesh cloth, as an important support and insulation auxiliary material during coil winding, can enhance the stability of the coil structure and optimize the interlayer insulation effect. Its fit, tension control, and laying uniformity during winding, together with the coil winding tightness, determine the transformer's insulation strength, heat dissipation efficiency, and short-circuit withstand capability.

[0003] In the current production process of dry-type transformer coils, the winding of the mesh cloth mostly relies on manual winding by workers. Specifically, workers need to hold one end of the mesh cloth against the coil roller and control the winding speed and tension based on experience. This is not only labor-intensive, but also makes it difficult to ensure the fit and uniformity of each turn of the mesh cloth. Wrinkles, misalignment, or uneven gaps between layers of the mesh cloth often occur.

[0004] Meanwhile, when manually winding the mesh cloth, it is difficult for workers to control the winding angle and speed, and it is difficult to make the mesh cloth form a regular tapered winding shape on the coil roller. This makes it difficult to form uniform support between the mesh cloth and the coil, reducing the support stability. This problem can easily cause uneven stress distribution inside the transformer, resulting in local stress concentration, which in turn reduces the insulation performance and mechanical stability of the coil and shortens the service life of the transformer. Therefore, it is necessary to design a dry-type transformer coil winding device.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0048] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0049] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0050] Reference Figures 1 to 4 As shown, this embodiment of the invention provides a dry-type transformer coil winding device, including a workbench 1. The workbench 1 serves as the supporting foundation of the entire device, providing a stable installation platform for each functional component. A support 11 is fixedly installed at one end of the upper part of the workbench 1. The support 11 is tightly connected to the workbench 1 by bolts to ensure the structural stability of the subsequent power components during operation. A drive motor 12 is installed on the support 11 by bolts. The drive motor 12 is a servo motor. A main assembly plate 13 is coaxially installed at the output end of the drive motor 12. The main assembly plate 13 rotates synchronously with the drive motor 12 to provide stable rotational support for the roller.

[0051] A main limiting ring 131 is fixedly installed on one side of the main assembly plate 13. The main limiting ring 131 and the main assembly plate 13 are designed as an integral structure to ensure connection strength. Multiple main limiting grooves 132 are opened on the main limiting ring 131. The main limiting grooves 132 are evenly distributed in a circular shape to achieve circumferential positioning of the roller.

[0052] A slide groove 142 is provided on the upper part of the other end of the worktable 1. The slide groove 142 is a straight groove structure. A one-way short lead screw 14 is rotatably connected inside the other end of the worktable 1. The one-way short lead screw 14 is connected to the inner wall of the worktable 1 through a bearing to ensure smooth rotation. A one-way slider 141 that can slide along the slide groove 142 is threadedly connected to the rod body of the one-way short lead screw 14. Rotating the one-way short lead screw 14 can drive the one-way slider 141 to move along the slide groove 142, realizing the distance adjustment when the roller is clamped, and adapting to coil rollers of different lengths.

[0053] A bracket 143 is bolted to the upper part of the unidirectional slider 141 to provide support. A bearing seat 144 is bolted to the upper part of the bracket 143. The bearing seat 144 is the prior art and has a bearing inside to reduce rotational friction. An auxiliary assembly plate 15 is rotatably connected to the bearing seat 144. The auxiliary assembly plate 15 and the main assembly plate 13 are coaxially arranged to jointly support the two ends of the roller.

[0054] An auxiliary limiting ring 151 is fixedly installed on one side of the auxiliary assembly plate 15. The auxiliary limiting ring 151 is symmetrical to the main limiting ring 131 to ensure that the roller is subjected to balanced force. Multiple auxiliary limiting grooves 152 are provided on the auxiliary limiting ring 151. The number of auxiliary limiting grooves 152 is the same as that of the main limiting grooves 132 and their positions correspond to ensure the coaxiality of the roller during installation.

[0055] A roller 16 is installed between the main assembly plate 13 and the auxiliary assembly plate 15. The roller 16 is the direct carrier for winding the mesh fabric. Multiple limiting plates 161 are installed inside the roller 16 by bolts. The limiting plates 161 are evenly distributed along the axial direction of the roller 16, which enhances the structural strength of the roller 16 and realizes the positioning function. The two ends of the limiting plate 161 are respectively engaged with the main limiting groove 132 and the auxiliary limiting groove 152. The engaging structure realizes the synchronous rotation of the roller 16 with the main and auxiliary assembly plates, ensuring that there is no relative displacement of the roller 16 during the winding process, and solving the problem of mesh fabric offset caused by the easy shaking of the coil roller during manual winding.

[0056] See Figures 5 to 7As shown, a position adjustment component 2 is installed on one side of the workbench 1. The position adjustment component 2 is used to control the winding position of the mesh cloth. The position adjustment component 2 includes an intermediate plate 21 fixedly installed on one side of the workbench 1. The intermediate plate 21 is a horizontally arranged rectangular plate and is tightly connected to the workbench 1 by bolts. A rectangular hole 211 is opened in the middle of the intermediate plate 21. The rectangular hole 211 is arranged along the length of the intermediate plate 21 to provide a channel for the movement of subsequent components. An intermediate box 22 is installed on the lower end face of the intermediate plate 21 by bolts. The intermediate box 22 is a rectangular box body and plays a role in protecting the internal transmission components and reducing the impact of dust and impurities on the transmission accuracy.

[0057] An adjustment motor 23 is bolted to the outer wall of one end of the intermediate box 22. The adjustment motor 23 is a stepper motor with the function of controlling the rotation angle. The output end of the adjustment motor 23 extends into the intermediate box 22 and is coaxially mounted with a one-way long lead screw 231. The one-way long lead screw 231 is rotatably connected to the intermediate box 22 through a bearing to ensure smooth rotation.

[0058] A one-way sliding sleeve 232 is threadedly connected to the body of the one-way long lead screw 231. The inner wall of the one-way sliding sleeve 232 is provided with an internal thread that is compatible with the one-way long lead screw 231. Linear motion is achieved through the transmission of the one-way long lead screw 231. A horizontal plate 233 is bolted to the lower end of the one-way sliding sleeve 232. The horizontal plate 233 is a horizontally set rectangular plate that serves as a connection and support. Vertical plates 234 are bolted to both sides of the upper part of the horizontal plate 233. The vertical plates 234 are vertically set rectangular plates with their upper ends passing through the rectangular hole 211 and extending to the top of the middle plate 21.

[0059] The upper part of the vertical plate 234 is bolted with an adapter plate 24. The adapter plate 24 is a horizontally set rectangular plate used to install the subsequent material placement part. The vertical plate 234 can slide along the rectangular hole 211, which is suitable for constraining the movement direction of the one-way sliding sleeve 232 on the one-way long screw 231. Through the cooperation between the vertical plate 234 and the rectangular hole 211, the one-way sliding sleeve 232 can be prevented from rotating synchronously with the one-way long screw 231, ensuring that it only moves axially along the one-way long screw 231, thereby realizing the adjustment of the winding position of the mesh cloth.

[0060] See Figures 7 to 9As shown, a material placement assembly 3 is installed on the adapter plate 24. The material placement assembly 3 is used to stably place the mesh fabric roll, ensuring uniform tension when the mesh fabric is unrolled, and solving the problem of unstable tension caused by manual unrolling of the mesh fabric. The material placement assembly 3 includes a main material placement frame 31 installed on one side of the adapter plate 24 by bolts. A main rotating ring 311 is rotatably connected to the upper part of the main material placement frame 31. The main rotating ring 311 is connected to the main material placement frame 31 by bearings to ensure smooth rotation. Three sets of main limiting blocks 312 are fixedly installed on one side of the main rotating ring 311. The main limiting blocks 312 are evenly distributed in a circle to achieve circumferential positioning of the material placement part.

[0061] On the other side of the adapter plate 24, an auxiliary material rack 32 is installed by bolts. The auxiliary material rack 32 and the main material rack 31 are symmetrical in structure and together provide support for both ends of the material placement part. A threaded sleeve 321 is fixedly installed on the upper part of the auxiliary material rack 32. The inner wall of the threaded sleeve 321 is provided with internal threads (not shown in the figure). A threaded shaft 322 is connected to the threaded sleeve 321. Rotating the threaded shaft 322 can realize axial movement, which facilitates the installation and disassembly of the material placement part. An auxiliary rotating ring 323 is rotatably connected to one end of the threaded shaft 322. The auxiliary rotating ring 323 is connected to the threaded shaft 322 through a bearing to ensure that it can rotate freely. Three sets of auxiliary limiting blocks 324 are fixedly installed on one side of the auxiliary rotating ring 323. The number of auxiliary limiting blocks 324 is the same as that of the main limiting blocks 312 and their positions correspond to ensure the coaxiality of the material placement part during installation.

[0062] A feeding roller 33 is installed between the main feeding frame 31 and the auxiliary feeding frame 32. The feeding roller 33 is used to fit the mesh fabric roll. Its surface is smooth and has moderate hardness to prevent damage to the mesh fabric. The feeding roller 33 is provided with a positioning groove 331 that is adapted to the main limiting block 312 and the auxiliary limiting block 324. The positioning groove 331 is set along the axial direction of the feeding roller 33. Through the cooperation of the auxiliary limiting block 324 and the main limiting block 312 with the positioning groove 331, the feeding roller 33 can rotate synchronously with the main and auxiliary rotating rings.

[0063] See Figure 7 and Figures 9 to 11 As shown, a cutting assembly 4 is installed on the adapter plate 24. The cutting assembly 4 is used to cut the mesh fabric during the winding process and adjust the winding shape of the mesh fabric. Specifically, during the process of feeding the mesh fabric on the feeding roller 33 to the coil roller 16, the two sides of the mesh fabric are precisely cut to ensure that the width of the mesh fabric matches the winding requirements of the coil roller 16. At the same time, the cutting angle of the cutting part is adjusted by power so that the mesh fabric can naturally form a regular conical winding state when it is wound to the coil roller 16, which solves the problem that it is difficult to control the taper by manual winding and causes uneven support of the mesh fabric.

[0064] The cutting assembly 4 includes two sets of baffles 41 bolted to the adapter plate 24. The two sets of baffles 41 are symmetrically distributed on the adapter plate 24 and are located on both sides of the feeding roller 33. This provides a stable installation base for the subsequent cutting components and also initially limits the mesh fabric conveying path to prevent lateral deviation during mesh fabric conveying.

[0065] Movable holes 411 are provided on both sets of baffles 41. The movable holes 411 are designed as arc-shaped strips, and their curvature is adapted to the rotation trajectory of the cutting part, providing sufficient space for the movement of the cutting part. A cutting plate 42 is hinged to one side of the baffle 41. The part of the cutting plate 42 away from the hinge end can pass through the movable holes 411 and move freely, ensuring that the cutting plate 42 can rotate smoothly around the hinge point.

[0066] Cutting blades 43 are fixedly installed on the end of the cutting plate 42 facing the mesh cloth by bolts. The two sets of cutting blades 43 correspond to the two side edges of the mesh cloth respectively. Only the excess part on both sides of the mesh cloth is cut off, while the main part of the mesh cloth used for winding in the middle remains intact. The cutting blades 43 are made of high-speed steel, which can cut the mesh cloth stably for a long time and is not prone to wear and dulling. The cutting direction of the cutting blades 43 can cut off the two side edges of the mesh cloth conveyed by the feeding roller 33, and the cut is flat and burr-free. This avoids gaps between the mesh cloth layers due to irregular cuts, which would affect the insulation strength and structural compactness of the coil.

[0067] Assembly frames 44 are fixedly installed on the outer sides of both sets of baffles 41. The assembly frames 44 are tightly connected to the baffles 41 by bolts to ensure structural stability. An electric push rod 45 is hinged to the middle of the assembly frame 44. The electric push rod 45 uses a linear drive element and has adjustable extension speed and thrust. The output end of the electric push rod 45 is hinged to the middle of the cutting plate 42. Through the extension and retraction of the electric push rod 45, the cutting plate 42 can be driven to rotate around the hinge point with the baffle 41, thereby driving the cutting blade 43 to adjust the cutting angle.

[0068] When it is necessary to adjust the cutting width of the mesh fabric to fit the conical winding, the rotation angle of the cutting plate 42 can be changed by controlling the extension and retraction of the electric push rods 45 on both sides, so that the spacing and angle between the cutting blades 43 on both sides meet the requirements of the conical winding.

[0069] Specifically, as the mesh fabric is fed and wound onto the coil roller 16, the distance between the two sets of cutting blades 43 gradually increases according to the parameters required for the tapered winding of the coil roller 16. The rotation angle of the corresponding cutting plate 42 is independently controlled by the electric push rods 45 on both sides, causing the left cutting blade 43 to slowly shift to the left and the right cutting blade 43 to slowly shift to the right. The distance between the two sets of cutting blades 43 gradually increases during the winding process, thereby gradually increasing the width of the main body of the mesh fabric. When the mesh fabric with gradually changing width is wound onto the coil roller 16, the cross-section of the wound mesh fabric will naturally form a regular tapered shape, which meets the support requirements of the dry-type transformer coil for the tapered winding of the mesh fabric and solves the problem that manual winding makes it difficult to control the tapered shape, resulting in uneven support between the mesh fabric and the coil.

[0070] See Figure 9 and Figure 10 As shown, a waste discharge assembly 5 is installed on the baffle 41. The waste discharge assembly 5 is used to promptly handle the mesh fabric waste generated by the cutting assembly 4, preventing waste from accumulating inside the equipment or on the mesh fabric conveying path, thus affecting the normal operation of the equipment and the mesh fabric winding quality.

[0071] The waste discharge assembly 5 includes a discharge motor 51 bolted to the outside of a side baffle 41. The discharge motor 51 is a servo motor with constant speed and torque. The output end of the discharge motor 51 passes through the baffle 41 and is coaxially mounted with a discharge roller 52. The discharge roller 52 is a prior art material, and its surface is covered with a rubber anti-slip layer, which can enhance the friction with the mesh waste and ensure that the waste can be stably clamped and conveyed. The axis of the discharge roller 52 is parallel to the discharge direction of the mesh waste. When the cutting blade 43 cuts and generates waste, the discharge motor 51 drives the discharge roller 52 to rotate, which can actively convey and discharge the waste.

[0072] A guide plate 53 is bolted to the adapter plate 24 and located below the discharge roller 52. The guide plate 53 is made of smooth stainless steel plate and can guide the discharged waste material, so that the waste material falls into the outside of the designated equipment along the arc of the guide plate 53, thereby improving the automation level of the equipment.

[0073] Working principle: First, the operator rotates the one-way short screw 14 to drive the one-way slider 141 to slide along the slide groove 142, adjusts the distance between the main assembly plate 13 and the auxiliary assembly plate 15, and places the roller 16 between the two, so that the two ends of the inner limiting plate 161 of the roller 16 are respectively inserted into the main limiting groove 132 and the auxiliary limiting groove 152, thus completing the circumferential positioning and axial clamping of the roller 16.

[0074] Simultaneously rotate the threaded shaft 322 on the auxiliary feeding rack 32 to push the auxiliary rotating ring 323 to cooperate with the main rotating ring 311 to clamp the feeding roller 33, so that the feeding roller 33 is engaged with the main and auxiliary limiting blocks through the positioning groove 331. Then, one end of the mesh cloth on the feeding roller 33 is led out and initially attached to the starting winding position of the roller 16 through the gap between the two sets of baffles 41 of the cutting component 4.

[0075] Next, based on the requirements of the tapered winding of the roller 16, the number of layers of mesh fabric and the width requirements, the speed of the drive motor 12 is set to control the rotation speed of the roller 16, and the rotation parameters of the adjustment motor 23 are set to control the movement position of the unidirectional long screw 231 driving the unidirectional sliding sleeve 232, ensuring that the material placement component 3 and the cutting component 4 reach the specified position. At the same time, the extension and retraction rate of the electric push rods 45 on both sides is set to determine the expansion range of the spacing between the cutting blades 43. After the parameters are set, the drive motor 12 is started, which drives the main assembly plate 13 to rotate synchronously. Through the engagement of the limiting plate 161 with the main and auxiliary limiting grooves, the drive roller 16 rotates stably and the mesh fabric winding begins.

[0076] During the winding process, the feeding roller 33 rotates synchronously with the main rotating ring 311 and the auxiliary rotating ring 323 under the traction of the mesh cloth, and stably feeds the mesh cloth to the roller 16. The electric push rods 45 on both sides of the cutting assembly 4 extend and retract independently according to the preset parameters, pushing the cutting plate 42 to rotate along the movable hole 411, causing the left cutting blade 43 to shift to the left and the right cutting blade 43 to shift to the right. The distance between the two sets of cutting blades 43 gradually increases, cutting only the two sides of the mesh cloth, so that the width of the middle main body gradually changes. The gradually changed mesh cloth is wound onto the roller 16 to form a regular conical cross section.

[0077] At the same time, the discharge motor 51 starts, driving the discharge roller 52 to rotate.
