Description

Technical Field

[0001] This utility model relates to the field of insulating paper manufacturing technology, and in particular to an insulating paper surface metal foreign object detection mechanism and insulating paper production equipment. Background Technology

[0002] Composite insulating paper is a key basic material in fields such as power equipment and electronic components. Its reliability and stability directly affect the safe operation and service life of the entire equipment system. This type of insulating paper is usually made from cellulose, polyester film or non-woven fabric as the matrix, and is made through special processes such as impregnation, coating or lamination. It is required to have excellent electrical insulation strength, mechanical toughness and heat resistance.

[0003] Currently, in the production and quality inspection of insulating paper, traditional testing methods mainly rely on manual visual inspection. This method is not only labor-intensive and inefficient, but also affected by factors such as personnel fatigue and subjective judgment differences, making it difficult to guarantee the consistency and reliability of the test results. It also has an extremely high rate of missed detection for micron-sized metal particles.

[0004] In addition, existing online testing equipment often has limited functionality, and the testing station is independent of the hot pressing and shaping process, resulting in a dispersed production line layout, which increases the equipment footprint and overall cost. Utility Model Content

[0005] On one hand, this application provides a metal foreign object detection mechanism for the surface of insulating paper, including a bracket, and a conveyor roller is rotatably arranged inside the bracket. A conveyor belt is provided at the output end of the conveyor roller, and a metal detector for detecting metal foreign objects on the surface of composite insulating paper is provided above the conveyor belt. A fixed frame is provided at the input end of the conveyor roller, and a pushing mechanism is fixedly arranged above the fixed frame. The pushing mechanism is used to push the composite insulating paper to be conveyed below the metal detector.

[0006] Preferably, the pushing mechanism includes a mounting block fixedly connected to the fixed frame, and an electric telescopic rod is fixedly installed on the mounting block. The output end of the electric telescopic rod slides through the mounting block and is fixedly connected to a connector, and a push block is fixedly installed on the connector, thereby realizing the precise pushing of the composite insulating paper and ensuring that it stably reaches the detection position.

[0007] Preferably, a hollow cylinder is fixedly mounted on the mounting block, and a sliding rod is slidably mounted inside the hollow cylinder. The sliding rod is fixedly connected to the connecting piece, which enhances the rigidity of the pushing mechanism, prevents the pushing block from shaking, and improves the reliability of the pushing action.

[0008] Preferably, in another aspect, this application also provides an insulating paper production equipment with an insulating paper surface metal foreign object detection mechanism, including a support frame disposed below a fixed frame, and a connecting rod fixedly disposed above the support frame. A heating base is fixedly disposed on the connecting rod, and a placement plate is placed on the heating base. A top plate is fixedly disposed at the end of the connecting rod away from the support frame, and a multi-stage cylinder is fixedly disposed on the top plate. A hot pressing plate is fixedly disposed at the output end of the multi-stage cylinder, and the hot pressing plate cooperates with the heating base to hot press the composite insulating paper on the placement plate. This integrates the metal foreign object detection and the hot pressing process into one unit, reducing the equipment footprint and overall cost, and improving production efficiency.

[0009] Preferably, at least two limiting strips are fixedly provided on the heating base, and the limiting strips are used to clamp the placement plate, which can reliably clamp the placement plate and prevent it from shifting during the hot pressing process, thus ensuring the stability of the hot pressing quality.

[0010] Preferably, the hot press plate is equipped with a heating element, and the heating element is electrically connected to an external temperature controller. The combination of the heating element and the temperature controller enables precise temperature control and improves the heat resistance and consistency of the composite insulating paper.

[0011] Preferably, the placement plate is made of polytetrafluoroethylene (PTFE) material and has an anti-stick coating on its surface. The PTFE placement plate and the anti-stick coating effectively prevent the composite insulating paper from sticking together, making it easy to pick up and put down and reducing surface contamination.

[0012] This utility model provides a metal foreign object detection mechanism and insulating paper production equipment on the surface of insulating paper, which, compared with the prior art: This invention integrates hot pressing and metal foreign object detection functions to construct a compact continuous production system. It uses an automated metal detector to replace inefficient manual visual inspection, significantly improving detection efficiency and reliability in detecting micron-sized metal foreign objects. The electric telescopic rod and the push mechanism with a guide structure enable precise and stable delivery of the insulating paper. The originally scattered hot pressing and detection stations are integrated into one, optimizing the production line layout, effectively reducing equipment footprint and overall cost, and ultimately achieving a comprehensive improvement in production efficiency and product reliability.

[0016] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0017] Please refer to Figure 1 This utility model provides a metal foreign object detection mechanism for the surface of insulating paper, including a support 1, with a conveyor roller 10 rotatably arranged inside the support 1. A conveyor belt 11 is provided at the output end of the conveyor roller 10, and a metal detector 12 for detecting metal foreign objects on the surface of composite insulating paper is arranged above the conveyor belt 11. A fixed frame 13 is provided at the input end of the conveyor roller 10, and a pushing mechanism 2 is fixedly arranged above the fixed frame 13. The pushing mechanism 2 is used to push the composite insulating paper to be conveyed below the metal detector 12. The composite insulating paper is carried and conveyed by the conveyor line composed of the conveyor roller 10 and the conveyor belt 11. At the same time, the metal detector 12 fixed on the support 1 continuously scans the surface of the insulating paper passing below it, realizing the automation of metal foreign object detection on the surface of composite insulating paper, replacing the inefficient and unreliable manual visual inspection, improving detection efficiency and consistency, and effectively capturing micron-sized metal particles. The conveyor belt 11 is an existing conveying device, and the metal detector 12 is an existing detection device for detecting metal foreign objects on the surface of insulating paper.

[0018] like Figure 2 and Figure 3As shown, the pushing mechanism 2 includes a mounting block 20 fixedly connected to the fixed frame 13, and an electric telescopic rod 21 is fixedly installed on the mounting block 20. The output end of the electric telescopic rod 21 slides through the mounting block 20 and is fixedly connected to a connector 22. A push block 23 is fixedly installed on the connector 22. After receiving a signal, the electric telescopic rod 21 extends, and its output end drives the push block 23 to move forward through the connector 22, thereby smoothly pushing the insulating paper onto the conveyor belt 11.

[0019] To enhance the rigidity of the pushing mechanism 2 and prevent the push block 23 from shaking, a hollow cylinder 24 is fixedly installed on the mounting block 20, and a sliding rod 25 is slidably installed inside the hollow cylinder 24, and the sliding rod 25 is fixedly connected to the connecting piece 22.

[0020] Please refer to Figure 4 On the other hand, this application also provides an insulating paper production equipment with an insulating paper surface metal foreign object detection mechanism, including a support frame 30 disposed below a fixed frame 13, and a connecting rod 31 fixedly disposed above the support frame 30. A heating base 34 is fixedly disposed on the connecting rod 31, and a placement plate 36 is placed on the heating base 34. A top plate 310 is fixedly disposed at the end of the connecting rod 31 away from the support frame 30, and a multi-stage cylinder 32 is fixedly disposed on the top plate 310. A hot pressing plate 33 is fixedly disposed at the output end of the multi-stage cylinder 32, and the hot pressing plate 33 cooperates with the heating base 34 to hot press the composite insulating paper on the placement plate 36. The detection and hot pressing two independent workstations are integrated into one device, which optimizes the production line layout, reduces the equipment floor space and material transfer links, thereby reducing the overall cost and improving production efficiency.

[0021] In order to reliably hold the placement plate 36, at least two limiting strips 35 are fixedly provided on the heating base 34, and the limiting strips 35 are used to hold the placement plate 36.

[0022] To achieve precise temperature control, a heating element is installed inside the hot press plate 33, and the heating element is electrically connected to an external temperature controller.

[0023] To prevent the composite insulating paper from sticking together, facilitate handling, and reduce surface contamination, the placement plate 36 is made of polytetrafluoroethylene and has an anti-stick coating on its surface.

[0024] In summary, during use, the composite insulating paper that has completed the previous process is first placed on the placement plate 36 on the heating base 34. Then, the multi-stage cylinder 32 drives the hot pressing plate 33 to press down. Under the combined heating and pressurization of the heating base 34, the insulating paper is hot-pressed and shaped. After hot pressing, the electric telescopic rod 21 of the push mechanism 2 is activated, and the push block 23 is pushed through the connecting piece 22 to smoothly push the placement plate 36 and the insulating paper on it onto the conveyor roller 10. Then, it is conveyed onto the conveyor belt 11. Finally, the placement plate 36 carrying the insulating paper passes under the metal detector 12 to realize the automatic and continuous detection of metal foreign objects on its surface. Thus, hot pressing and shaping and online detection are integrated into one, completing the continuous automated production and quality inspection process of the insulating paper.

[0025] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
