Description

Technical Field

[0001] This invention relates to the field of insulating paper ring technology, and in particular to a production line for milling and chamfering insulating paper rings. Background Technology

[0002] In the production and processing of transformer insulating paper rings, the milling and chamfering process is a crucial step that determines the product's precision and quality. Currently, the industry mainly uses a circular shearing machine to mill and chamfer insulating paper rings from cardboard raw materials. The circular shearing machine cuts the insulating paper into rings, and then the chamfers of the insulating paper are manually polished.

[0003] However, traditional methods of processing insulating paper rings have significant technical shortcomings, making it difficult to meet the demands of large-scale, high-precision production. On the one hand, manual processing is extremely inefficient, with unstable quality, failing to match the capacity requirements of modern production lines. Furthermore, prolonged operation can lead to hand fatigue and safety hazards. On the other hand, existing circular shearing machines generally lack effective waste constraint mechanisms. Although they can fix the cardboard center and drive its rotation through mechanical structures, using milling devices to complete the cutting process and form a "one ring of finished product, one ring of waste" structure, the connection between the waste ring and the finished product ring gradually weakens during processing. Due to the lack of real-time limiting and stable control of the waste, the rotating cardboard causes the waste ring to sway irregularly, shift, or even detach from the processing station. This erratic waste movement interferes with the milling device, affecting the milling process. Furthermore, the swaying waste indirectly affects the stability of the finished product ring, leading to quality defects such as burrs and gaps on the edges. This is especially problematic when processing multi-specification insulating paper rings with gradually decreasing diameters, where the boundary between waste and finished product becomes even more difficult to control, further reducing product precision and consistency.

[0004] In summary, the existing milling and chamfering process for insulating paper rings has technical drawbacks such as poor precision and easy movement of waste material. There is an urgent need for a milling and chamfering production line that can achieve automated processing, effectively constrain waste material displacement, and ensure product quality and consistency, so as to meet the industry's demand for large-scale production and high-quality products.

[0032] like Figure 1 , Figures 3-6 As shown, the material rotating device 2 and the milling and chamfering device 3 are located at the horizontal moving end point of the loading and unloading device 1.

The mounting plate 307 is fixedly installed on the guide rail slider of the second lifting execution unit 306.

[0035] like Figure 4 and Figures 7-11 As shown, two sets of rollers 303 are rotatably mounted on the support 302. Two rollers 304 are rotatably mounted and coaxially fixedly connected between the two sets of rollers 303. The axes of rollers 303 and rollers 304 are parallel to each other. The width of roller 303 is greater than the sum of the widths of the two rollers 304. A lifting actuator 308 is provided on the mounting plate 307. The lifting actuator 308 is composed of a cylinder. Its cylinder body is fixedly mounted on the mounting plate 307. A connecting plate is fixedly mounted on its output end. Two sets of rollers 303 corresponding to rollers 303 on the support 302 are rotatably mounted on the connecting plate. Between the two sets of rollers 303 on the output end connecting plate of the lifting actuator 308, there are rollers 309 and 311.

[0037] The output end connection plate of the lifting actuator 308 is also provided with a pressure rod 313 that is driven to lift by the lifting actuator 5 312; the lifting actuator 5 312 is composed of a cylinder, the cylinder body is fixedly installed on the output end connection plate of the lifting actuator 308, the output end is fixedly installed with a connection plate, and the pressure rod 313 is fixedly installed on the connection plate.

[0038] Each set of mobile execution unit 301 has a lifting execution unit 315 on its guide rail slider; the lifting execution unit 315 is composed of a cylinder, the cylinder body of which is fixedly installed on the guide rail slider of the corresponding mobile execution unit 301, and a sliding mounting seat is fixedly installed on its output end; an elastic sliding rod 316 is slidably and elastically installed on the sliding mounting seat, the elastic sliding rod 316 is horizontally set and elastically connected to the sliding mounting seat through a compression spring; a push plate 317 is fixedly installed on the end of the elastic sliding rod 316 that points towards the material rotation device 2.

[0039] A dust cover 318 is fixedly installed on the mounting plate 307. The dust cover 318 covers the milling cutter 314 to suppress flying dust.

[0040] like Figure 1 and Figure 3 As shown, the support frame 4 has four sets, which are arranged around the material rotating device 2. In this embodiment, they are distributed at the four corners of the moving execution unit 301 arranged in a cross shape. As a specific implementation of this embodiment, several spheres are movably installed on the support frame 4 to facilitate the rotation of the cardboard raw material.

[0041] like Figure 1 As shown, the raw material rack 5 and the finished product rack 6 are arranged side by side within the transport range of the loading and unloading device 1.

[0042] The working steps of this embodiment are as follows: First, start the horizontal moving unit 101 and the vertical moving unit 102. The mounting frame 104 moves above the raw material rack 5. Start the vacuum adsorption device 105 to adsorb the paperboard raw material. Then move the paperboard raw material to the support frame 4. At this time, the paperboard raw material is located on the output end of the rotary actuator 201.

[0043] The second step involves activating the lifting actuator 315, causing the elastic sliding rod 316 and push plate 317 to rise; activating all the moving actuators 301, causing the elastic sliding rod 316 and push plate 317 to move towards the paperboard material, with the push plate 317 pushing the paperboard material to the center, placing it on the output end of the rotating actuator 201 and the support 302; and activating the lifting actuator 202, causing the pressure plate 203 to press down on the paperboard material.

[0044] Thirdly, the second moving execution unit 305 is activated, and the mounting plate 307 moves above the support 302; the second lifting execution unit 306 is activated, and the milling cutter 314 is activated. The mounting plate 307 moves downward, and the third lifting execution unit 308 drives the first roller 303 and the third roller 309 on its output end to move downward. The first roller 303 on the upper and lower sides of the cardboard material clamps the cardboard material, while the milling cutter 314 penetrates the cardboard material (at this time, the milling cutter 314 is located outside the first roller 303 on the lower side of the cardboard material); then the second moving execution unit 305 drives the milling cutter 314 into the cardboard material. Move a short distance so that the cutting surface of the milling cutter 314 contacts the processing surface of the cardboard material. Then, start the rotary actuator 201 to make the cardboard material start to rotate. After the cardboard material rotates slightly more than 180°, the milling cutter 314 mills the outer perimeter of the cardboard material into a circle and simultaneously completes the chamfering process, generating the outermost waste material. Finally, the milling cutter 314 moves a short distance to the outside of the cardboard material and then moves upward to detach from the cardboard material. The lifting actuator 308 drives the rollers 303 and 309 on its output end to move upward. In this way, the outer ring processing of the insulating paper ring is completed.

[0045] In the fourth step, the second moving execution unit 305 drives the milling cutter 314 to move into the paperboard material to the position between the two rollers 304. After the mounting plate 307 moves down, the third lifting execution unit 308 drives the first roller 303 and the third roller 309 on its output end to move down. The fourth lifting execution unit 310 drives the fourth roller 311 to move down. The fifth lifting execution unit 312 drives the pressure rod 313 to move down. The first roller 303 on the upper and lower sides of the paperboard material clamps the paperboard material and the waste generated in the third step. The third roller 309 and the inner roller 304 clamp the paperboard material. The fourth roller 311 and the outer roller 304 clamp the waste. The pressure rod 313 presses down the paperboard material and the waste. The milling cutter 314 penetrates the cardboard material and then moves a short distance inward, bringing its cutting surface into contact with the machined surface of the cardboard material. The rotary actuator 201 is then activated, causing the cardboard material to rotate. After rotating slightly more than 180°, the milling cutter 314 mills the outer perimeter of the cardboard material into a circle and simultaneously completes the chamfering process, generating new waste material. During the rotation of the cardboard material, the inner roller 304 rotates along with it, driving the outer roller 304 to rotate as well. The step rotation causes the cardboard raw material and waste to rotate together, and under the limiting action of the pressure bar 313, the waste is prevented from being misaligned. Finally, the milling cutter 314 first moves a small distance to the outside of the cardboard raw material, and then moves upward to detach from the cardboard raw material. The lifting actuator 308 drives the rollers 303 and 309 on its output end to move upward. The lifting actuator 4 310 drives the roller 311 to move upward. The lifting actuator 5 312 drives the pressure bar 313 to move upward. In this way, the inner ring of the insulating paper ring is processed.

[0046] In the fifth step, the support 302 and the mounting plate 307 move synchronously into the interior of the cardboard raw material, passing over the newly generated waste, and repeat the third and fourth steps to process the insulating paper rings with smaller diameters until the entire cardboard raw material is processed ring by ring from the outside to the inside. It should be noted here that, except for the insulating paper ring with the largest diameter (i.e. the insulating paper ring processed in the first step), when processing the outer ring of the other insulating paper rings, the hole created by the milling cutter 314 is located on the waste generated from processing the inner ring of the previous insulating paper ring, so as to avoid waste of resources.

[0047] Step 6: After all the insulating paper rings are processed, the components of the material rotating device 2 and the milling and chamfering device 3 return to their original positions. The loading and unloading device 1 transfers the processed insulating paper rings and waste materials together to the finished product rack 6. Finally, the insulating paper rings and waste materials are separated and processed.
