Description

Technical Field

[0001] The invention belongs to the technical field of coating and compounding of flexible materials, and in particular relates to double-sided compounding equipment and a coating and compounding method for composite materials. Background Art

[0002] With the rapid development of materials such as lithium batteries, optics, photovoltaics, shielding and flexible circuit board substrates, coating technology has become an indispensable processing method for flexible composite materials. Light, thin, short and small have become the technical core of current materials. It is particularly important to achieve low-tension operation of these materials, reduce residual stress, improve production efficiency, save production line layout space, and ensure the high-end quality of products. The existing composite method of multi-layer flexible composite materials mainly completes the semi-finished product production of the first side through the coating substrate sending, coating, drying, compounding and winding, and then completes the double-sided composite product through sending, coating, drying, compounding and winding:

[0003] Composite solution 1, such as Figure 1 As shown, the coating material is coated on the front side of the material through the coating device 11, and enters the suspension oven 13 through the guide wheel 12. Under the joint action of the upper air nozzle 13-1 and the lower air nozzle 13-2 of the oven, the material is non-contact dried. After leaving the oven 13, the guide wheel 14 guides the material between the composite rubber roller 16 and the composite steel roller 17, and the single-sided composite of the material is achieved on the bonding substrate 15, and then the process is repeated to achieve the double-sided bonding requirement of the material.

[0004] Composite solution 2: Figure 2 As shown, the coating material is coated on the front side of the material through the coating device 21, and enters the guide wheel type oven 23 through the guide wheel 22. Under the support of the oven support guide wheel 23-1, the material is contact dried. After leaving the oven 23, the guide wheel 24 guides the material between the composite rubber roller 26 and the composite steel roller 27, and the single-sided composite of the material is achieved on the bonding substrate 25, and then the process is repeated to achieve the double-sided bonding requirement of the material.

[0005] Composite solution 3: Figure 3 As shown, the coating material is coated on the front side of the material through the coating device 31, and is coated on the back side of the material through the coating device 38, and enters the suspension oven 33 through the guide wheel 32. Under the joint action of the upper air nozzle 33-1 and the lower air nozzle 33-2 of the oven, the material is non-contact dried. After leaving the oven 33, the guide wheel 34 guides the material between the composite rubber roller 36 and the composite steel roller 37, and the double-sided composite of the material is achieved on the bonding substrate 35 and the bonding substrate 39.

[0006] The above schemes 1 and 2 require two times of lamination to achieve the double-sided lamination requirements of the materials, which not only has high overall energy consumption and low yield, but also has high cost and low efficiency. Although scheme 3 can achieve double-sided lamination of materials at one time, and the overall energy consumption and efficiency are controlled, the materials will inevitably come into contact at the guide wheel 34 during the lamination process, which not only damages the adhesive surface, but also makes it impossible to effectively control the tension of the material running due to stickiness, which is prone to unstable product quality problems.

The suspension steering oven 3 includes a steering box 301, a steering fresh air system inlet 302, an upper steering air duct 303 and a lower steering air duct 304 arranged inside the steering box 301. The air duct 304, the upper turning air duct 303 and the lower turning air duct 304 are respectively installed with a plurality of upper turning nozzles 305 and a plurality of lower turning nozzles 306 on one side thereof, a turning channel 307 is formed between the plurality of upper turning nozzles 305 and the plurality of lower turning nozzles 306, the turning channel 307 is in an arc shape, one end of the turning channel 307 is connected to the discharge end of the suspension oven 2, and the other end of the turning channel 307 is connected to the feed end of the composite mechanism 4, so that the suspension turning oven 3 has a turning function in addition to the drying function;

[0031] Specifically, the upper turning air duct 303 and the lower turning air duct 304 inside the turning box 301 are arc-shaped structures and are interconnected. Fresh air enters through the turning fresh air system inlet 302, is pressurized by the internal fan and then dispersed in the upper turning air duct 303 and the lower turning air duct 304. A turning channel 307 is formed between the multiple upper turning nozzles 305 and the multiple lower turning nozzles 306, leaving enough space for the dried material to pass through. During operation, the wind pressure of the upper turning nozzle 305 and the lower turning nozzle 306 is uniform, so that the printed matter is suspended and runs in the oven.

[0033] In this way, the inlet of the turning channel 307 is arranged to transition with the discharge end of the suspension oven 2 in an arc shape, and the outlet of the turning channel 307 is arranged to transition with the feed end of the composite mechanism 4 in an arc shape, thereby ensuring that the material in the turning channel 307 is smoother and avoids bending.

The first substrate conveying component 401 and the second substrate conveying component 402 can realize functions such as unwinding and cutting of the material. The composite rubber roller 403 and the composite steel roller 404 press the substrate and the material together.

[0042] Working principle: When in use, the front coating component 101 realizes the front coating of the material, and the back coating component 103 realizes the back coating of the material, and enters the suspension oven 2 through the guide wheel 104, and then the upper nozzle 204 and the lower nozzle 205 work together to realize the non-contact drying of the material. After leaving the suspension oven 2, the suspension steering oven 3 guides the material between the composite rubber roller 403 and the composite steel roller 404, and fits the first substrate and the second substrate to realize the double-sided composite material, which not only realizes the high efficiency, high yield, high quality and low cost of the composite material process requirements At the same time, due to the design of the suspended steering oven 3, and the upper steering nozzle 305 and the lower steering nozzle 306 are arranged in the suspended steering oven 3, the wind pressure of the upper steering nozzle 305 and the lower steering nozzle 306 is uniform during operation. Under the joint action of the wind pressure on both sides, the material is kept in the middle to avoid contact with objects, thereby ensuring that the adhesive surface of the material is intact, improving the phenomenon that the material running tension cannot be effectively controlled due to sticking, avoiding the problem of unstable product quality, and better adapting to the composite requirements in quality, efficiency, energy consumption, and cost under the new situation.
