Description

Technical Field

[0001] This utility model belongs to the field of coating and composite technology of flexible materials, and specifically relates to a double-sided coating and composite equipment. Background Technology

[0002] With the rapid development of materials for lithium batteries, optics, photovoltaics, shielding, and flexible circuit board substrates, coating technology has become an indispensable processing method for flexible composite materials. Lightweight, thin, short, and small dimensions have become the core technologies for these materials. Achieving low-tension operation, reducing residual stress, improving production efficiency, saving production line layout space, and ensuring high-end product quality are particularly important. Current multilayer flexible composite material lamination methods mainly involve sending the substrate, coating, drying, laminating, and rewinding to complete the semi-finished product on the first side, and then completing the double-sided laminated product through sending, coating, drying, laminating, and rewinding.

[0003] Composite Scheme 1, such as Figure 1 As shown, the coating material is coated on the front side by the coating device 11, and enters the suspended oven 13 through the guide wheel 12. Under the combined action of the upper air nozzle 13-1 and the lower air nozzle 13-2 of the oven, the material is dried in a non-contact manner. After exiting the oven 13, the material is guided between the composite rubber roller 16 and the composite steel roller 17 by the guide wheel 14, and the material is laminated on the bonding substrate 15 to achieve single-sided lamination. Then the process is repeated to achieve double-sided lamination of the material.

[0004] Composite Scheme Two, such as Figure 2 As shown, the coating material is coated on the front side by the coating device 21, and enters the guide roller oven 23 through the guide roller 22. Under the support of the oven support guide roller 23-1, the material is dried in contact. After exiting the oven 23, the guide roller 24 guides the material between the composite rubber roller 26 and the composite steel roller 27, and the material is laminated on the bonding substrate 25 on one side. Then the process is repeated to achieve the double-sided bonding requirement of the material.

[0005] Composite Scheme 3, such as Figure 3 As shown, the coating material is coated on the front side by coating device 31 and on the back side by coating device 38. It then enters the suspended oven 33 through guide wheel 32. Under the combined action of the upper air nozzle 33-1 and the lower air nozzle 33-2 of the oven, the material is dried in a non-contact manner. After exiting the oven 33, the material is guided by guide wheel 34 between composite rubber roller 36 and composite steel roller 37, and the material is laminated on both sides of the bonding substrate 35 and bonding substrate 39.

[0006] The above schemes 1 and 2 require two lamination processes to achieve the double-sided bonding of the materials, which not only results in high overall energy consumption and low yield, but also high cost and low efficiency. Although scheme 3 can achieve double-sided lamination of the materials in one step and controls the overall energy consumption and efficiency, the guide wheel 34 will inevitably come into contact during the lamination process. This not only damages the adhesive surface, but also makes it impossible to effectively control the tension of the materials due to adhesion, which can easily lead to unstable product quality. Utility Model Content

[0007] (1) Technical problems to be solved

[0008] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a double-sided coating and laminating equipment. This equipment aims to solve the problem that in existing double-sided coating equipment, the material inevitably comes into contact with the guide wheel during the lamination process, which not only damages the adhesive surface but also makes it difficult to effectively control the tension of the material during operation due to adhesion, easily leading to unstable product quality.

[0009] (2) Technical solution

[0010] To solve the above-mentioned technical problems, this utility model provides a double-sided coating and laminating equipment, which includes a double-sided coating mechanism, a suspended drying oven, a suspended turning drying oven, a laminating mechanism, and a finished product winding mechanism. The suspended turning drying oven includes a turning box, a turning fresh air system inlet, an upper turning air duct and a lower turning air duct arranged inside the turning box. Multiple upper turning nozzles and multiple lower turning nozzles are respectively installed on the side of the upper turning air duct and the lower turning air duct that are close to each other. A turning channel is formed between the multiple upper turning nozzles and the multiple lower turning nozzles. The turning channel is arc-shaped. One end of the turning channel is connected to the discharge end of the suspended drying oven, and the other end of the turning channel is connected to the feed end of the laminating mechanism.

[0011] Preferably, the inlet and outlet of the steering channel have a 90-degree rounded corner structure.

[0012] Furthermore, the double-sided coating mechanism includes a front coating assembly, a coating roller, a reverse coating assembly, and guide wheels.

[0013] Furthermore, the suspended oven includes an oven body, an upper air duct and a lower air duct installed inside the oven body, and multiple upper nozzles and multiple lower nozzles respectively installed on the side of the upper air duct and the lower air duct that are close to each other. The deflector box is installed on the right side of the oven body.

[0014] Furthermore, the upper and lower steering nozzles are staggered.

[0015] Furthermore, the oven body is equipped with a fresh air system inlet and a return air door.

[0016] Furthermore, the composite mechanism includes a first substrate conveying assembly, a second substrate conveying assembly, a composite rubber roller, and a composite steel roller.

[0017] (3) Beneficial effects

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. This utility model achieves front coating of materials through a front coating component and reverse coating of materials through a reverse coating component. The materials enter the suspended oven through guide wheels, and then achieve non-contact drying of materials under the combined action of upper and lower nozzles. After exiting the suspended oven, the suspended turning oven guides the materials between the composite rubber roller and the composite steel roller, and they are bonded to the first substrate and the second substrate to achieve double-sided composite of materials. This realizes the process requirements of high efficiency, high yield, high quality and low cost of composite materials.

[0020] 2. This utility model, by setting a suspended turning oven at the outlet of the suspended oven, eliminates the guide wheel at the outlet and sets an upper turning nozzle and a lower turning nozzle inside the suspended turning oven. During operation, due to the uniform air pressure of the upper and lower turning nozzles, the material is kept in the middle under the combined action of the air pressure on both sides, avoiding contact with objects. This ensures the integrity of the adhesive surface of the material coating, improves the phenomenon that the tension of the material cannot be effectively controlled due to adhesion, avoids the problem of unstable product quality, and better adapts to the new situation of composite materials in terms of quality, efficiency, energy consumption, and cost.

[0027] This specific embodiment is a double-sided coating and laminating device, which can be used in special drying and laminating fields where the desiccant cannot be redirected by guide rollers. Its structural schematic diagram is shown below. Figure 4-5 As shown, the equipment includes a double-sided coating mechanism 1, a suspended drying oven 2, a suspended rotating drying oven 3, a composite mechanism 4, and a finished product winding mechanism 5. The suspended drying oven 2 and the suspended rotating drying oven 3 achieve non-contact drying of the material after coating. The composite mechanism 4 has heating, cooling, and room temperature operation functions. The finished product winding mechanism 5 can realize functions such as winding and cutting of composite materials. The suspended rotating drying oven 3 includes a rotating box 301, a rotating fresh air system inlet 302, an upper rotating air duct 303 set inside the rotating box 301, and a lower rotating air duct. Multiple upper turning nozzles 305 and multiple lower turning nozzles 306 are respectively installed on the side of the air duct 304, the upper turning air duct 303 and the lower turning air duct 304 that are close to each other. A turning channel 307 is formed between the multiple upper turning nozzles 305 and the multiple lower turning nozzles 306. The turning channel 307 is arc-shaped. One end of the turning channel 307 is connected to the discharge end of the suspended oven 2, and the other end of the turning channel 307 is connected to the feed end of the composite mechanism 4. In this way, the suspended turning oven 3 has a turning function in addition to the drying function.

[0028] Specifically, the upper turning air duct 303 and the lower turning air duct 304 inside the turning box 301 are arc-shaped structures and interconnected. Fresh air enters through the turning fresh air system inlet 302, and after being pressurized by the internal fan, it is drawn into the upper turning air duct 303 and the lower turning air duct 304. A turning channel 307 is formed between multiple upper turning nozzles 305 and multiple lower turning nozzles 306, leaving enough space for the material to be dried to pass through. During operation, because the air pressure of the upper turning nozzles 305 and the lower turning nozzles 306 is uniform, the printed matter floats and moves inside the oven.

[0029] like Figure 5As shown: In this embodiment, the inlet and outlet of the steering channel 307 have a 90-degree rounded corner structure.

[0030] This design ensures that the material inside the turning channel 307 is more evenly distributed, preventing bending. The inlet of the turning channel 307 and the outlet of the suspended oven 2 are connected by an arc, and the outlet of the turning channel 307 and the inlet of the composite mechanism 4 are connected by an arc.

[0031] like Figure 4 As shown: In this embodiment, the double-sided coating mechanism 1 includes a front coating assembly 101, a coating roller 102, a reverse coating assembly 103, and a guide wheel 104.

[0032] In use, the front coating component 101 achieves front coating of the material, the back coating component 103 achieves back coating of the material, and the material enters the suspended oven 2 through the guide wheel 104.

[0033] like Figure 5 As shown: In this embodiment, the suspended oven 2 includes an oven body 201, an upper air duct 202 and a lower air duct 203 installed inside the oven body 201. Multiple upper nozzles 204 and multiple lower nozzles 205 are respectively installed on the side of the upper air duct 202 and the lower air duct 203 that are close to each other. The turning box 301 is installed on the right side of the oven body 201.

[0034] Specifically, the turning box 301 is sealed and installed on the right side of the oven body 201 to prevent dust from entering during the drying process. The upper air duct 202 and the lower air duct 203 are fixedly installed inside the oven body 201 by means of a hanging rod. The upper turning air duct 303 and the lower turning air duct 304 are fixedly installed inside the turning box 301 by means of a hanging rod.

[0035] The suspended drying oven 2 and the suspended rotating drying oven 3 may or may not have a heating function during drying. The heating source includes, but is not limited to, steam, hot water, electricity, natural gas, infrared, etc. The upper air duct 202, lower air duct 203, upper rotating air duct 303 and lower rotating air duct 304 can also be interconnected and supplied with air by a single fan, thereby reducing the number of fans and adding a stirring fan to fully mix the heated air and circulating air.

[0036] like Figure 5 As shown: In this embodiment, the upper turning nozzle 305 and the lower turning nozzle 306 are staggered, and the upper nozzle 204 and the lower nozzle 205 are staggered. This arrangement can better balance the position of the material and ensure stability during drying.

[0037] In this embodiment, a fresh air system inlet 206 and a return air door 207 are installed on the oven body 201.

[0038] like Figure 4 and Figure 5 As shown: In this embodiment, the composite mechanism 4 includes a first substrate conveying assembly 401, a second substrate conveying assembly 402, a composite rubber roller 403, and a composite steel roller 404. The first substrate conveying assembly 401 and the second substrate conveying assembly 402 can realize the functions of unwinding and cutting materials. The composite rubber roller 403 and the composite steel roller 404 press the substrate and the material together.

[0039] Working principle: During use, the front coating assembly 101 achieves front coating of the material, and the back coating assembly 103 achieves back coating. The material enters the suspended drying oven 2 via guide wheels 104. Then, under the combined action of the upper nozzle 204 and lower nozzle 205, non-contact drying of the material is achieved. After exiting the suspended drying oven 2, the suspended turning oven 3 guides the material between the composite rubber roller 403 and the composite steel roller 404, where it is bonded to the first and second substrates to achieve double-sided lamination. This not only realizes the high efficiency, high yield, high quality, and low cost required for composite material processing, but also... Furthermore, due to the design of the suspended rotating oven 3, and the upper rotating nozzle 305 and lower rotating nozzle 306 installed inside the suspended rotating oven 3, the air pressure of the upper rotating nozzle 305 and lower rotating nozzle 306 is uniform during operation. Under the combined action of the air pressure on both sides, the material is kept in the middle, avoiding contact with objects. This ensures the integrity of the adhesive surface of the material coating, improves the phenomenon that the tension of the material cannot be effectively controlled due to adhesion, avoids the problem of unstable product quality, and better adapts to the requirements of the new situation in terms of quality, efficiency, energy consumption, and cost of composite materials.

[0040] All technical features in this embodiment can be freely combined according to actual needs.

[0041] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
