Description

Technical Field

[0001] This application relates to the field of composite insulating paper preparation technology, specifically an adhesive coating device for preparing composite insulating paper. Background Technology

[0002] Composite insulating paper is a high-performance insulating material, usually composed of multiple layers of materials with different properties. It has excellent electrical insulation, high temperature resistance, mechanical strength and chemical corrosion resistance, and is widely used in motors, transformers, electronic devices and other fields.

[0003] Composite insulating paper typically consists of a substrate layer, a functional layer, and an adhesive layer. One method involves applying a liquid adhesive to the substrate layer and rolling it. However, because the adhesive content is not consistently maintained during the coating process, variations in adhesive content can lead to reduced uniformity after lamination, thus affecting the processing quality of the composite insulating paper. Furthermore, when processing insulating paper of different widths, misalignment may occur during transport, making accurate bonding impossible during lamination. Therefore, to address these issues, an adhesive coating device for preparing composite insulating paper is proposed. Utility Model Content

[0026] Please see Figure 1-3 As shown, an adhesive coating device for preparing composite insulating paper includes a housing 1, a support plate 11, a side plate 16, a bracket 18, and a horizontal tube 20.

[0027] The housing 1 is rotatably connected to a first roller 2, a pressure roller 3, a second roller 6, and a coating roller 7. The coating roller 7 is disposed on one side of a support plate 11. The support plate 11 is fixedly installed inside the bottom end of the housing 1, and the top surface of the support plate 11 is fixedly connected to two symmetrically distributed side plates 16. One end of each side plate 16 has an elongated hole for moving a horizontal tube 20. The horizontal tube 20 is distributed in an inclined manner. The bracket 18 is fixedly installed on the top of the housing 1. An electric push rod 19 is fixedly installed on the bracket 18, and the telescopic end of the electric push rod 19 is connected to the end of the horizontal tube 20.

[0028] The housing 1 is provided with two first idler rollers 2 and pressure rollers 3 inside, and a substrate layer and a functional layer that make up the composite insulating paper are respectively provided between adjacent first idler rollers 2 and pressure rollers 3; the outer wall of the housing 1 is rotatably connected to two unwinding rollers 5, and the surfaces of the two unwinding rollers 5 are respectively provided with a substrate layer and a functional layer, and the substrate layer is disposed between the second idler roller 6 and the coating roller 7.

[0029] Furthermore, the first idler roller 2 and the pressure roller 3 are used for limiting the position of the substrate layer and the functional layer during the conveying process, and the adhesive is applied by the coating roller 7. The second idler roller 6 is used to support the substrate layer, so as to achieve stable conveying and uniform application of adhesive.

[0030] The coating roller 7 has several evenly distributed fine holes on its surface. One end of the coating roller 7 is connected to the housing 1, and the other end of the coating roller 7 is rotatably connected to the surface of the fixed tube 10. The fixed tube 10 is fixedly installed to the inner wall of the housing 1. The support plate 11 is fixedly installed with a conveying pump 12, and the conveying pump 12 is connected to the inside of the fixed tube 10 through a connecting pipe 13. The first idler roller 2 and the pressure roller 3 are movably sleeved with a first guide plate 4, and the second idler roller 6 and the coating roller 7 are sealed with a second guide plate 8. The first guide plate 4 and the second guide plate 8 are rotatably connected to a screw 9 inside, and the screw 9 is threadedly connected to the side walls of the housing 1 on both sides.

[0031] Specifically, the fixed tube 10 enables the coating roller 7 to rotate stably. The delivery pump 12 delivers the adhesive to the fixed tube 10 through the connecting tube 13, and fills the coating roller 7 by squeezing it out from the fine holes to achieve uniform coating.

[0032] A crossbar 14 is fixedly installed on one side of the side plate 16. Both ends of the crossbar 14 are connected to the side plate 16. The crossbar 14 is located on one side of the horizontal tube 20. Several evenly distributed infrared rangefinders 15 are fixedly connected to the bottom of the crossbar 14. The infrared rangefinders 15 are electrically connected to the controller of the electric push rod 19, and the infrared rangefinders 15 are distributed correspondingly to the substrate layer. The side wall of the side plate 16 is rotatably connected to the guide roller 17, and the outer wall of the housing 1 is rotatably connected to the take-up roller 26.

[0033] Furthermore, the crossbar 14 is used for the installation of the infrared rangefinder 15, which is used to monitor the thickness of the applied adhesive. When the thickness is large, the electric push rod 19 pushes the horizontal tube 20 down, so that the horizontal tube 20 scrapes off the excess adhesive.

[0034] The horizontal tube 20 is connected to the movable plate 22 by a spring 21. The movable plate 22 slides in a sealed manner inside the horizontal tube 20. The movable plate 22 is fixedly connected to the connecting plate 23, and the connecting plate 23 passes through the top of the horizontal tube 20 and extends to the outside. The middle parts of the movable plate 22 and the connecting plate 23 are interconnected. The support plate 11 is fixedly connected to the pump body 24, and the pump body 24 is fixedly connected to one end of the horizontal tube 20 through a connecting pipe 25.

[0035] Furthermore, when the adhesive coating thickness is small, the electric push rod 19 shortens and pulls the horizontal tube 20 upward. The horizontal tube 20 drives the connecting plate 23 to press against the guide roller 17. At this time, the movable plate 22 squeezes the adhesive inside the horizontal tube 20, causing the adhesive to be squeezed out from the middle of the movable plate 22 and the connecting plate 23 and adhere to the bottom surface of the functional layer. During lamination, the substrate layer with less adhesive adheres to the functional layer containing a portion of adhesive, thereby ensuring a balanced adhesive content and improving the coating quality.

[0036] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description.
