Description

Technical Field

[0001] This utility model relates to the technical field of mica tape processing, and in particular to a uniform drying device for applying adhesive to the surface of mica tape. Background Technology

[0002] Mica tape is a fire-resistant and insulating material that is directly wound around copper wire. The preparation process of mica tape usually includes steps such as applying adhesive to fiberglass cloth, laminating with mica paper, applying adhesive a second time, high-temperature curing, and winding.

[0003] Existing technology, such as patent publication number CN221855148U, discloses a gluing device capable of omnidirectional and uniform gluing, relating to the field of mica paper processing technology. It includes a processing box, a first gluing mechanism, and a second drying lamp. A fixing frame is welded to the inner wall of the processing box, and a mounting frame is fixedly connected to the top of the fixing frame. This omnidirectional and uniform gluing device controls a motor to drive a rotating rod to rotate, thereby causing an extrusion block to periodically extrude the hose. This allows the glue in the glue tank to be evenly applied to the surface of the central rod through the glue head, and then applied to the mica paper by the central rod. The improved gluing device achieves uniform gluing by strictly controlling the amount of glue applied and ensuring that the glue adheres evenly to the surface of the central rod. It also includes a first gluing mechanism and a second gluing mechanism for gluing both sides of the mica paper, achieving omnidirectional gluing and solving the problem of existing gluing devices being unable to apply glue evenly in all directions.

[0004] The aforementioned existing patent literature has the following defects: when drying the mica tape after coating with adhesive using a drying lamp, the pungent gas generated by the adhesive during drying will be released in large quantities along with the water vapor. This will cause a large amount of odor to be generated when the device is drying the mica tape evenly, which will easily cause inconvenience to the operators and reduce their comfort. Moreover, the heat generated by the drying lamp to dry the mica tape after coating with adhesive cannot be effectively utilized, resulting in energy waste. Utility Model Content

Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Therefore, the purpose of this utility model is to provide a uniform drying device for coating mica tape with adhesive. By placing the adhesive bucket in a preheating box and guiding the gas discharged from the odor removal box to the preheating box, the heat is rationally utilized, avoiding energy waste. At the same time, the adhesive in the adhesive bucket is preheated, and the preheated adhesive is fully melted, avoiding uneven adhesive in the adhesive bucket, thus improving the coating quality of mica tape and the drying effect after coating.

[0023] Reference Figures 1-3 This utility model discloses a uniform drying device for applying adhesive to the surface of mica tape, including a glue tank 1, a processing box 2, and an adhesive application mechanism, a support roller assembly, and a dryer installed inside the processing box 2. The adhesive application mechanism, support roller assembly, and dryer can all be existing products. Specifically, in this embodiment, the adhesive application mechanism includes a glue supply pump 7 fixed to the processing box 2, a protective frame 8 fixed inside the processing box 2, and a glue outlet 9 and an adhesive application roller 10 mounted on the protective frame 8. The glue outlet 9 is located above the adhesive application roller 10. The glue supply pump 7 is connected to the glue tank 1 and the glue outlet 9 respectively through pipes. The support roller assembly includes multiple rollers 12 fixed inside the processing box 2, which are used to transport the mica tape. The dryer uses a drying lamp 11. The glue in the glue tank 1 is pumped to the glue outlet 9 by the glue supply pump 7. Then, the glue is evenly sprayed onto the coating roller 10 by the glue outlet 9. The coating roller 10 is rotated by a servo motor. The glue is applied to the surface of the mica tape by the coating roller 10. The glue on the surface of the mica tape is evenly dried by the drying lamp 11, so that the glue applied to the surface of the mica tape can be quickly solidified. The mica tape is placed on multiple rollers 12. The mica tape can be driven through the interior of the processing box 2 by the external unwinding equipment.

[0024] It also includes an odor removal box 3, an exhaust fan 4, and a preheating box 5 installed on the processing box 2. The odor removal box 3 has an activated carbon adsorption layer installed inside. The glue bucket 1 is fixed inside the preheating box 5. One end of the exhaust fan 4 is connected to the inside of the processing box 2, and the other end of the exhaust fan 4 is connected to the other end of the odor removal box 3. One end of the odor removal box 3 is connected to the air inlet 503 of the preheating box 5.

[0025] Using the above structure, the irritating gas generated by the drying lamp 11 in the processing box 2 during glue drying is drawn into the odor removal box 3 by the energized operation of the induced draft fan 4. The activated carbon adsorption layer in the odor removal box 3 reduces the pungent odor in the air and exhausts the air, thus optimizing the processing environment in the workshop and improving the comfort of the workers. Placing the glue bucket 1 in the preheating box 5 preheats the glue in the glue bucket 1, ensuring that the glue is fully melted and preventing uneven glue distribution in the glue bucket 1, thereby improving the quality of mica tape coating and the drying effect after coating. Since the gas discharged from the odor removal box 3 still carries heat after the glue is dried, guiding the gas discharged from the odor removal box 3 to the preheating box 5 achieves rational utilization of heat and avoids energy waste.

[0026] Reference Figure 2 In detail, in this embodiment, the preheating box 5 includes a preheating cylinder 501 fixed to the top of the processing box 2. An air duct 502 is opened inside the preheating cylinder 501, and the glue bucket 1 is made of stainless steel, a heat-conducting material. By opening the air duct 502 inside the preheating cylinder 501, the gas discharged from the odor removal box 3 will exchange heat with the glue bucket 1 before being discharged. The glue bucket 1 is made of stainless steel, which ensures that the heat from the hot air flowing through the preheating cylinder 501 can be transferred to the glue in the glue bucket 1, thus preheating the glue.

[0027] Reference Figure 1 In detail, in this embodiment, a gas collection hood 6 is fixed to the top of the inner cavity of the processing box 2, and the top of the gas collection hood 6 is connected to one end of the induced draft fan 4 through a pipe. Example

[0028] Reference Figure 2 Based on the same concept as in Embodiment 1, this uniform drying device for coating mica tape surface also includes a spiral-shaped air duct 502 fixed inside the preheating cylinder 501. The spiral design of the air duct 502 allows for sufficient heat exchange of the gas discharged from the odor removal box 3 as it passes through the air duct 502. One end of the air duct 502 is connected to the air inlet 503 of the preheating box 5, and the other end of the air duct 502 is connected to the air outlet 504 of the preheating box 5. The air inlet 503 of the preheating box 5 is connected to one end of the odor removal box 3 through a pipe. The gas discharged from the odor removal box 3 enters the preheating cylinder 501 through the air inlet 503 of the preheating box 5, and after heat exchange, it is discharged to the outside through the air inlet 503 of the preheating box 5.

[0029] Working principle: First, the mica tape enters through the feed port at one end of the processing box 2 and is guided and conveyed by multiple rollers 12. The glue supply pump 7 pumps the glue in the glue bucket 1 to the glue outlet 9. Then, the glue outlet 9 sprays the glue evenly onto the coating roller 10. The coating roller 10 is rotated by a servo motor. The glue is applied to the surface of the mica tape by the coating roller 10. The glue on the surface of the mica tape is evenly dried by the drying lamp 11. Start the blower 4. The blower 4 draws the irritating gas generated by the drying lamp 11 in the processing box 2 to the odor removal box 3. The activated carbon adsorption layer in the odor removal box 3 can adsorb the irritating gas. The adsorbed gas will pass through the preheating box 5 to preheat the glue in the glue bucket 1 located in the preheating box 5 before being discharged.

[0030] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
