Abstract
Description
Technical Field
[0001] This utility model relates to the field of insulating cover film processing technology, and in particular to an insulating cover film folding device. Background Technology
[0002] Insulating covering film is a protective material specifically designed for electrical equipment and electronic components, aiming to provide superior electrical insulation performance while possessing excellent physical and chemical stability. It is typically made of polymeric materials such as polyester (PET), polyimide (PI), or polyvinyl chloride (PVC), which have good heat resistance, corrosion resistance, and mechanical strength, effectively preventing current leakage, short circuits, and other electrical faults.
[0003] In humid environments, moisture may seep into internal electrical components through the untreated edges of the cover film, causing short circuits or other electrical faults. In addition, untreated edges are more fragile and are easily worn down by friction or external factors, thereby reducing insulation performance. This wear not only increases the risk of tearing, but may also cause the cover film to break during installation or use, further affecting its protective effect.
[0004] Therefore, it is necessary to design an insulating cover film folding device to solve the above-mentioned technical problems. Utility Model Content
[0005] To overcome the above-mentioned shortcomings, this utility model provides an insulating cover film folding device.
[0006] The technical implementation scheme of this utility model is as follows: an insulating covering film folding device includes a frame, a controller, a motor, rollers, a conveyor belt, a rubber sleeve, a rotating rod, and a rolling wheel. The controller is fixedly connected to the front of the frame, and the motor is fixedly connected to the front of the frame. The motor is located below the controller and is electrically connected to the controller. Rollers are rotatably connected to both sides of the frame. One of the rollers is fixedly connected to the output shaft of the motor. A conveyor belt is sleeved between the two rollers, and a rubber sleeve is fixedly connected to the conveyor belt. A rotating rod is rotatably connected to the left side of the frame. Rolling wheels are fixedly connected to both sides of the rotating rod, and both rolling wheels abut against the rubber sleeve.
[0007] In a preferred embodiment of this utility model, the rubber sleeve is made of a soft material.
[0008] In a preferred embodiment of this utility model, it further includes a slide rod, a guide block, and a spring. Slide rods are slidably connected to both sides of the left side of the frame. A guide block is fixedly connected to one end of each slide rod. The distance between each guide block and the corresponding rolling wheel is equal to the thickness of the insulating covering film. Each guide block is slidably sleeved on the rotating rod. A spring is connected between each guide block and the frame. Each spring is wound around the corresponding slide rod.
[0009] In a preferred embodiment of this utility model, it further includes a fixed frame, a dust collection paper roll, dust removal rollers, a powerful electrostatic demagnetizer, and a limiting cylinder. Fixed frames are fixedly connected to both sides of the right side of the frame. A dust collection paper roll is rotatably connected between the middle of the two fixed frames. Dust removal rollers are rotatably connected to both sides of the two fixed frames. The two dust removal rollers abut against the dust collection paper roll. A powerful electrostatic demagnetizer is fixedly connected to both sides of the two fixed frames. The two powerful electrostatic demagnetizers are located on one side of the corresponding dust removal roller. A limiting cylinder is rotatably connected to the left side of the two fixed frames.
[0010] In a preferred embodiment of the present invention, the device further includes mounting blocks, a collection frame, and a handle. Mounting blocks are symmetrically and fixedly connected to the left side of the frame, and a collection frame is slidably placed between the two mounting blocks. A handle is fixedly connected to the left side of the collection frame.
[0011] In a preferred embodiment of the present invention, a baffle is also included, which is fixedly connected to the left side of the frame and is located above the collection frame.
[0012] Compared with the prior art, this utility model has the following advantages: 1. This utility model achieves automatic edge folding of the insulating cover film through the coordinated action of the controller, motor, roller, conveyor belt, and rolling roller. The motor drives the roller to move the conveyor belt smoothly, ensuring stable feeding of the insulating cover film. The rolling roller applies uniform pressure to the edge to achieve efficient edge folding, which can effectively protect the edge of the cover film, extend its service life, increase the edge strength, reduce the possibility of tearing, and provide a tighter seal to prevent the intrusion of these impurities.
[0013] 2. This utility model achieves precise guidance and folding of the edge of the insulating covering film through the synergistic action of the guide block, spring and rolling wheel. The spring enables the guide block to adapt to film materials of different thicknesses and ensures that its edge is accurately upright. The rolling wheel then applies uniform pressure to complete the folding, which improves the folding accuracy and stability and reduces the operation error caused by the change of film thickness.
[0014] 3. This utility model neutralizes the static electricity on the membrane surface through a powerful electrostatic demagnetizer to prevent dust adsorption. Subsequently, the dust removal roller uses adhesive materials or bristles to remove dust and fine particles, while the dust collection paper roll continuously rolls up to carry away impurities, ensuring the cleanliness of the dust removal roller, improving the cleaning effect, reducing the impact of dust on the membrane material, and also improving the quality and reliability of subsequent processing. It is particularly suitable for applications with high precision requirements. Attached Figure Description

[0021] Example: An insulating cover film folding device, such as Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the device includes a frame 1, a controller 101, a motor 2, rollers 3, a conveyor belt 4, a rubber sleeve 5, a rotating rod 6, and a pressing wheel 7. The controller 101 is screwed onto the left front side of the frame 1. The motor 2 is also screwed onto the left front side of the frame 1, located below the controller 101 and electrically connected to it. Rollers 3 are rotatably connected to both sides of the frame 1. The roller 3 on the left is welded to the output shaft of the motor 2. A conveyor belt 4 is fitted between the two rollers 3. A rubber sleeve 5, made of soft material, is glued to the outer surface of the conveyor belt 4. A rotating rod 6 is rotatably connected to the upper left side of the frame 1. Pressing wheels 7, which fold the insulating covering film, are welded to both the front and rear sides of the rotating rod 6. Both pressing wheels 7 abut against the rubber sleeves 5. When this device is needed, it is controlled by the controller... The controller 101 sends a signal to the motor 2 to start it. The output shaft of the motor 2 drives the left roller 3 to rotate counterclockwise. The power is transmitted to the right roller 3 through the conveyor belt 4, causing the conveyor belt 4 to move continuously. The insulating cover film to be processed is placed on the conveyor belt 4. The friction provided by the rubber sleeve 5 ensures that it moves steadily to the left. As the conveyor belt 4 moves, the insulating cover film gradually approaches and enters the area of the rolling wheel 7. The rolling wheel 7 is in close contact with the rubber sleeve 5 on the conveyor belt 4. The rotation applies pressure to the edge of the insulating cover film to achieve the edge folding process. The rotating rod 6 supports the rotation of the rolling wheel 7 to ensure that the rolling process is uniform and continuous. After being processed by the rolling wheel 7, the insulating cover film continues to move to the left along the conveyor belt 4 until it has completely passed through the rolling area. Then, the controller 101 shuts off the motor 2 to complete the edge folding process.
[0022] like Figure 1 and Figure 3 As shown, it also includes a slide bar 8, a guide block 9, and a spring 10. The left side of the frame 1 is slidably connected to the front and rear sides of the slide bar 8. The ends of the two slide bars 8 that are close to each other are welded with guide blocks 9 for guiding the edge of the insulating covering film to stand upright. The distance between the two guide blocks 9 and the corresponding rolling roller 7 is equal to the thickness of the insulating covering film. The two guide blocks 9 are slidably sleeved on the rotating rod 6. The two guide blocks 9 are connected to the frame 1 with springs 10. The two springs 10 are wound around the corresponding slide bars 8. As the conveyor belt 4 moves, the insulating covering film gradually approaches and enters the area of the guide block 9. The guide block 9, through the action of the spring 10, can adapt to the insulating covering film of different thicknesses and guide its edge to stand upright. After being guided upright by the guide block 9, the edge of the insulating covering film enters the area of the rolling roller 7. The rolling roller 7 is in close contact with the rubber sleeve 5 on the conveyor belt 4. By rotating, pressure is applied to the edge of the insulating covering film to achieve the edge folding process. The spring 10 enables the guide block 9 to automatically adjust the pressure when the insulating covering film of different thicknesses passes through, ensuring the accuracy and stability of the edge guidance.
[0023] like Figure 1 , Figure 2 and Figure 4 As shown, it also includes a fixed frame 11, a dust collection paper roll 12, dust removal rollers 13, a powerful electrostatic demagnetizer 14, and a limiting cylinder 15. Fixed frames 11 are welded to both the front and rear right sides of the frame 1. A dust collection paper roll 12 is rotatably connected between the middle of two fixed frames 11. Dust removal rollers 13 are rotatably connected to both the left and right sides of the two fixed frames 11, and the two dust removal rollers 13 abut against the dust collection paper roll 12. Powerful electrostatic demagnetizers 14 are installed on both the left and right sides of the two fixed frames 11 by screws. The two powerful electrostatic demagnetizers 14 are located on the opposite sides of the corresponding dust removal rollers 13. A limiting insulating cover is rotatably connected to the left end of the two fixed frames 11. Before the insulating covering film enters the dust removal roller 13, the limiting cylinder 15 for film movement passes through a powerful electrostatic demagnetizer 14. This powerful electrostatic demagnetizer 14 can effectively neutralize the static electricity on the surface of the insulating covering film and prevent dust adsorption. After electrostatic demagnetization, the insulating covering film continues to move forward and enters the area of the dust removal roller 13. The dust removal roller 13 rotates and uses the adhesive material or bristles on its surface to remove dust and fine particles from the surface of the insulating covering film. The dust removal roller 13 abuts against the dust collection paper roll 12. The dust collection paper roll 12 rolls continuously, taking away the dust and impurities transferred from the dust removal roller 13, ensuring that the dust removal roller 13 is always kept clean.
[0024] like Figure 1 and Figure 5 As shown, it also includes mounting blocks 16, collection frames 17, handles 18, and baffles 19. Mounting blocks 16 are symmetrically welded to the front and back of the left side of the frame 1. A collection frame 17 is slidably placed between the two mounting blocks 16. A handle 18 is welded to the left side of the collection frame 17. A baffle 19 is welded to the upper part of the left side of the frame 1. The baffle 19 is located above the collection frame 17 to prevent the folded insulating film from overflowing during transmission and to ensure that the insulating film falls into the collection frame 17. The collection frame 17 is used to receive the folded insulating film. When the collection frame 17 is full, the collection frame 17 can be pulled out from the mounting blocks 16 by pulling the handle 18. After cleaning the folded insulating film in the collection frame 17, the collection frame 17 can be pushed back to its original position to the right.
