Description

Technical Field

[0001] This utility model relates to the field of composite film processing technology, and in particular to composite film processing equipment. Background Technology

[0002] With the development of various industries, single-material films can hardly meet diverse functional requirements. For example, food packaging needs to simultaneously possess barrier and preservation properties, while the electronics field requires films with good insulation and electromagnetic shielding properties. Traditional processing methods have limitations, leading to the emergence of composite film processing equipment. This equipment combines multiple materials through different processes, improving their physical and chemical properties, enhancing product quality and performance, meeting the market's ever-growing demand for high-performance materials, and driving the development of related industries.

[0003] Existing technologies for composite film processing equipment suffer from several shortcomings, primarily in inaccurate coating thickness control and low drying efficiency. Some traditional equipment cannot precisely adjust the coating thickness during the coating process, leading to uneven film thickness and consequently affecting its physical properties and application performance. Furthermore, the drying process after coating often requires a considerable amount of time, extending the production cycle and reducing overall production efficiency. Simultaneously, some equipment is prone to generating bubbles and defects during the coating process, further impacting film quality and adhesion. Therefore, this composite film processing equipment is proposed to address these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a composite film processing equipment, which aims to improve the problem of difficulty in setting the thickness of the coating in the prior art.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this invention, the gear structure drives the doctor blade coating structure, significantly improving the control of coating thickness and uniformity. The high-precision transmission of the gear system ensures that the doctor blade moves on the substrate surface at a stable speed and pressure, resulting in uniform coating. This motion control allows for flexible adjustment of coating thickness according to different materials and application requirements, ensuring the quality of each film layer. By optimizing the doctor blade angle and pressure, the equipment can effectively prevent the generation of bubbles and coating defects, further improving the adhesion and smoothness of the film layer, thereby achieving the effect of controlling coating thickness and uniformity.

[0015] 2. In this invention, the drying structure operates in conjunction with a heat pump fan structure. The heat pump structure efficiently provides heat, enabling the fan-driven drying structure to operate effectively. The fan causes hot air to be evenly blown onto the surface of the coated composite film, quickly removing moisture from the coating and allowing it to dry rapidly. This successfully solves the problem of an uncured coated composite film, avoiding subsequent processing issues such as adhesion and deformation caused by an uncured film, ensuring a smooth processing flow, and resolving the problems that an uncured coated composite film can cause to subsequent processing.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1 to 4 This utility model provides an embodiment of a composite film processing equipment, including a coating shell 1, which provides the necessary structural strength to ensure the stability and durability of the equipment during coating. A coating agent hopper 2 is fixedly connected inside the coating shell 1 for storing the coating agent. A drive assembly for driving the coating process is fixedly connected outside the coating shell 1. A coating transfer roller 6 is rotatably connected inside the coating shell 1, used to transfer the coating agent from the surface of the coating material roller 5 to the surface of the coating back roller, ensuring uniform coating. A coating back roller 7 is rotatably connected inside the coating shell 1 to fix the composite film, working in conjunction with the coating material roller 5 to achieve uniform coating. A feed roller 8 is fixedly connected inside the coating shell 1 to fix the composite film and rotate it to move it towards the feed direction. A discharge roller 9 is fixedly connected inside the coating shell 1 to fix the composite film and rotate it through static friction to move it towards the discharge direction. Two hydraulic cylinders 10 are fixedly connected outside the coating shell 1 to convert hydraulic energy into mechanical energy. A protective cylinder 11 is fixedly connected outside the hydraulic cylinders 10 to prevent... The hydraulic rod 12 is slidably connected inside the hydraulic cylinder 10 to prevent collisions and damage from external objects. It transmits the force generated by the hydraulic cylinder 10. A connecting block 13 is fixedly connected to the outside of the hydraulic rod 12, connecting the hydraulic rod 12 and the sliding plate 14 to maintain the integrity of the structure. The sliding plate 14 is fixedly connected to the outside of the connecting block 13, allowing it to slide back and forth under the cooperation of the hydraulic structure. A coating blade 15 is fixedly connected inside the sliding plate 14 to control the thickness of the coating. The drive component includes a motor 3, which converts electrical energy into mechanical energy. The motor 3 is fixedly connected to the outer wall of the coating housing 1. A rotating shaft 4 is fixedly connected inside the motor 3. The torque generated by the motor 3 is transmitted to the coating rollers 5 through the rotating shaft 4, thereby driving them to operate. The coating rollers 5 are rotatably connected to the outside of the rotating shaft 4, and the coating agent is adhered to the surface of the coating rollers 5 by rotation. A drive gear 16 is fixedly connected to the outside of the rotating shaft 4. The drive gear 16 transmits power from one component to another by meshing with the driven gear 17, realizing the conversion of mechanical motion.

[0025] Reference Figure 4The coating shell 1 is externally fixedly connected to a drying shell 19, which provides support and reduces heat loss during drying. An electric heater 20 is internally fixedly connected to the drying shell 19, converting electrical energy into heat energy. A conduit 21 is internally fixedly connected to the electric heater 20, transmitting the heat generated by the heater 20. A heat pump 22 is externally fixedly connected to the conduit 21, converting high-temperature heat energy into high-temperature, high-pressure gas. A hot gas storage tank 23 is externally fixedly connected to the heat pump 22, storing the high-temperature, high-pressure gas. Two conduits 24 are externally fixedly connected to the hot gas storage tank 23, transporting the high-temperature, high-pressure gas. A hot gas release device 25 is externally fixedly connected to the conduit 24, releasing the high-temperature, high-pressure gas to a fan 26 and driving the fan 26 to rotate. The top of the hot gas release device 25 is fixedly connected to the fan 26, which guides hot air to the material surface, promoting heat transfer and allowing the material to absorb heat more quickly, thereby accelerating the drying process. A water collection block 27 is internally fixedly connected to the drying shell 19, allowing water to accumulate... The drying shell 19 has multiple fixed blocks 28 inside to fix the circulating fan 29 inside the drying shell 19, thus maintaining the stability of the structure. The circulating fan 29 is fixedly connected to the bottom of the fixed block 28. The circulating fan 29 is responsible for guiding the hot air inside the dryer back to the heating area and the water accumulation block 27 to form a closed loop system. The drying shell 19 has a circulating baffle block 30 inside. Through reasonable airflow distribution, dead corners can be reduced, ensuring that all materials can fully contact the hot air, thereby improving drying efficiency.

[0026] Reference Figure 3 , Figure 5 The externally fixedly connected to the rubber-coated transfer roller 6 is a driven gear 17, which meshes with the driving gear 16 to drive the rubber-coated transfer roller 6 to rotate. The externally fixedly connected to the rubber-coated back roller 7 is a driven gear 18, which meshes with the driven gear 17 to drive the rubber-coated back roller 7 to rotate. The externally fixedly connected to the drying shell 19 is a motor 31, which converts electrical energy into mechanical energy. The internally fixedly connected to the motor 31 is a feed roller 32, which fixes the composite film and rotates to move the composite film towards the feed direction. The internally rotatably connected to the drying shell 19 is a discharge roller 33, which fixes the composite film and rotates through static friction to move the composite film towards the discharge direction.

[0027] Working Principle: First, the composite film is fixed onto the feed roller 8, the adhesive-coated backing roller 7, and the discharge roller 9. At this time, the coating machine inside the sliding plate 14 starts working, and the motor 3 drives the structural shaft 4 and the coating roller 5 to rotate counterclockwise. During this process, adhesive adheres to the surface of the coating roller 5. Simultaneously, the motor 3 drives the hydraulic rod 12, protected by the protective cylinder 11, to extend and retract. As the hydraulic rod 12 extends and retracts, the connecting block 13 connects to the sliding plate 14, sliding back and forth in the groove inside the coating housing 1 to the desired position. In this way, the coating doctor blade 15 can cooperate with the coating roller 5 to adjust the coating thickness.

[0028] The driving gear 16 outside the rotating shaft 4 drives the driven gear 17 to rotate through meshing, allowing the coating agent to be evenly stored on the surface of the coating transfer roller 6. Next, the driven gear 17 meshes with the driven gear 18, further adhering the coating agent to the surface of the composite film on the coating back roller 7. Then, the rotation of the composite film and the coating back roller 7 drives the feed roller 8 to feed the material and the discharge roller 9 to discharge the material.

[0029] Furthermore, after the composite film is coated, some reagent may remain on its surface that has not been evenly coated, which can cause difficulties in subsequent processing. At this point, the composite film is fixed to the discharge roller 33 and the feed roller 32. Motor 31 drives the feed roller 32 to rotate, and the static friction between the composite film and the discharge roller 33 drives the discharge roller 33 to rotate as well. Next, the heater 20 converts electrical energy into heat energy, which is transferred to the heat pump 22 via conduit 21. The heat pump 22 then converts the high-temperature heat energy into high-temperature, high-pressure gas, which is stored in the heat storage tank 23. Afterward, the high-temperature, high-pressure gas is transferred to the heat release device 25 via conduit 24. Simultaneously, the heat release device 25 guides the high-temperature, high-pressure gas to the surface of the composite film through the exhaust fan 26, promoting heat transfer and allowing the composite film to absorb heat more quickly. The circulating baffle block 30 inside the drying shell 19 has a unique structure that reduces dead zones through reasonable airflow distribution, thereby improving drying efficiency. Meanwhile, air containing some moisture is guided back to the heating zone and water accumulation block 27 by the circulating fan 29, realizing the drying cycle.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
