Description

Technical Field

[0001] This utility model belongs to the technical field of fiberglass film coating equipment, specifically relating to a continuous film coating device. Background Technology

[0002] Fiberglass panels are widely used in RVs, vans, and other fields. During the production process, a thin film is applied to the surface of the fiberglass panel to achieve corrosion resistance, aging prevention, and enhanced aesthetics. An adhesive layer is then applied to the surface where the film is bonded to the fiberglass panel. Previously, this adhesive layer was applied using a spraying method. However, the spraying process causes the adhesive to atomize, resulting in poor hygiene in the production environment, frequent spray gun malfunctions, high cleaning frequency, low material utilization, strong odors during production, heavy burden on environmental protection equipment, and high operating costs. Utility Model Content

[0003] This utility model provides a continuous film coating device to solve the technical problems of poor production environment, easy malfunction of spray guns, and high frequency of spray gun cleaning caused by the spray coating process for fiberglass sheets in the prior art. This utility model includes: a film unwinding device; A scraper platform frame is located on the outlet side of the film unwinding device; The adhesive coating assembly is located on either side of the scraper platform frame; At least one drying oven is located on the outlet side of the scraper platform frame; A traction machine is located on the outlet side of the oven; The film unwinding device is used to release the film roll and output the film. The film passes sequentially through the doctor blade platform frame, the coating assembly, and the oven, and moves forward under the traction of the traction machine.

[0004] This invention uses a coating assembly to apply adhesive to a film in a fluid state. When the film passes through the doctor blade platform, the adhesive on the film surface is evenly spread by the doctor blade, replacing the traditional spraying process and avoiding the environmental pollution and low utilization rate caused by adhesive atomization.

[0005] Furthermore: the scraper platform frame includes: A platform frame is installed on the ground, and the length of the platform frame is adapted to the width of the film; The scraper, positioned above the platform frame, offers the following advantages: the platform frame acts as a backing for the film, allowing the film to remain flat under the reaction force of the scraper without affecting the squeezing effect.

[0006] Furthermore: the platform frame is provided with a crossbeam; the two ends of the scraper are provided with cylinders, and the cylinders are connected to the crossbeam; the cutting edge of the scraper faces the platform frame. The beneficial effect of this step is that by adjusting the height of the scraper, the distance between the scraper and the platform frame can be adjusted to accommodate films of different thicknesses and the thickness of the adhesive layer on their surface.

[0007] Further: the coating assembly includes: The support frame is set up on the ground; A linear slide rail is provided on the top surface of the bracket; A slide block is mounted on the linear slide rail, and the slide block is driven by a driving component. A glue-coating tank is mounted on the slide block. The glue-coating tank includes a tank body and a glue-coating pipe located at the lower part of the tank body. The glue-coating pipe faces the film. The beneficial effect of this step is that the slide block moves on the linear slide rail, which can drive the glue-coating tank on the slide block to move, thereby ensuring that the glue applied to the film surface is more even.

[0008] Furthermore: the tank is equipped with a pneumatic agitator, and compressed air is connected above the pneumatic agitator. The beneficial effect of this step is that the stirring speed of the pneumatic agitator can be adjusted by adjusting the pressure of the compressed air, ensuring that the materials are fully mixed.

[0009] Furthermore: both sides of the scraper platform frame are equipped with flattening devices; The flattening device includes at least two pairs of clamping wheels, which correspond to both sides of the film. The clamping wheels are used to clamp the edges of the film. The beneficial effect of this step is that the film on both sides of the scraper platform frame is flat by the flattening device, which is more conducive to scraping and ensures that the adhesive surface is flat.

[0010] Furthermore, a conveyor is provided between the coating assembly and the oven. The beneficial effects of this step are that the conveyor can carry the film forward, and the speed of the conveyor is slightly greater than the running speed of the film, which avoids downward deformation and eliminates the occurrence of scraper marks, ensuring that the adhesive on its surface will not affect each other before curing.

[0011] Furthermore: the film unwinding device includes an unwinding roller that passes through the film roll, and one end of the unwinding roller is connected to a power source, which includes a magnetic powder clutch. The beneficial effect of this step is that the release tension of the film can be controlled by the magnetic powder clutch, so that it can be stretched without being deformed.

[0012] The beneficial effects of this utility model are: 1. This application obtains a smooth adhesive layer by applying adhesive to the surface of a film and scraping the adhesive on the film with a doctor blade platform frame, which replaces the existing spraying process. This avoids the environmental pollution caused by the atomization of adhesive in the spraying process, and avoids the defects of low material utilization caused by the atomized adhesive escaping into the air. 2. The glue-spraying tank discharges the glue through a glue-spraying pipe. The diameter of the glue-spraying pipe is larger than the nozzle orifice of the spraying process, making it less prone to clogging and eliminating the need for frequent nozzle cleaning.

Detailed Implementation

[0016] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention. It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0017] Implementation of this application, for example Figure 1 and Figure 2 As shown, this utility model provides a continuous film coating device.

[0018] This utility model includes: a film unwinding device 1; The scraper platform frame 2 is located on the outlet side of the film unwinding device 1; The adhesive coating assembly 3 is located on either side of the scraper platform frame 2; At least one oven 4 is located on the outlet side of the scraper platform frame 2; Traction machine 5 is located on the outlet side of the oven 4; The film unwinding device 1 is used to release the film roll and output the film 8. The film 8 passes sequentially through the doctor blade platform frame 2, the coating assembly 3 and the oven 4, and moves forward under the traction of the traction machine 5.

[0019] This invention uses a coating assembly 3 to apply adhesive to a film 8 in a fluid state. When the film 8 passes through the scraper platform 2, the adhesive on the surface of the film 8 is evenly scraped by the scraper 21, replacing the traditional spraying process and avoiding the environmental pollution and low utilization rate caused by adhesive atomization.

[0020] Based on the above technical solution, the scraper platform frame 2 includes: Platform frame 22 is set on the ground, and the length of the platform frame 22 is adapted to the width of the film 8; The scraper 21 is positioned above the platform frame 22, which serves as the base for the film 8. This allows the film 8 to remain flat under the reaction force of the scraper 21, without affecting the scraping effect. The blade of the scraper 21 is at a certain distance from the surface of the film 8, which is equal to the thickness of the adhesive layer. The adhesive falls onto the surface of the film 8 in droplet form (affected by the surface tension of the adhesive itself). As the film 8 moves forward, the adhesive comes into contact with the blade of the scraper 21. The adhesive can only pass through the gap between the blade of the scraper 21 and the film 8. During this process, the adhesive is scraped flat.

[0021] Based on the above technical solution, the platform frame 22 is provided with a crossbeam; the two ends of the scraper 21 are provided with cylinders, and the cylinders are connected to the crossbeam; the cutting edge of the scraper 21 faces the platform frame 22. Under normal circumstances, vertical rods can be provided on both sides of the platform frame 22, and the two ends of the crossbeam are fixedly connected to the top of the vertical rods. The height of the scraper 21 can be adjusted by adjusting the extension length of the cylinder, and the distance between the scraper 21 and the platform frame 22 can be adjusted to adapt to films of different thicknesses and the thickness of the adhesive layer on their surface.

[0022] Based on the above technical solution, the adhesive coating assembly 3 includes: Support 31 is installed on the ground; A linear slide rail 32 is provided on the top surface of the bracket 31; The slide block 33 is mounted on the linear slide rail 32. The slide block 33 is driven by a driving component, which can be a cylinder or an electric push rod, etc. The extension and retraction of the cylinder or electric push rod drives the slide block 33 to achieve linear reciprocating motion on the linear slide rail 32. A glue-coating tank 34 is provided on the slide 33. The glue-coating tank 34 includes a tank body and a glue-coating pipe 341 provided at the lower part of the tank body. The glue-coating pipe 341 faces the film 8. The slide block 33 moves on the linear slide rail 32, which can drive the glue spraying tank 34 on the slide block 33 to move, thereby ensuring that the glue is sprayed onto the surface of the film 8 more evenly.

[0023] Based on the above technical solution, a pneumatic agitator 342 is provided inside the tank, and the tank is filled with adhesive material. Compressed air is connected above the pneumatic agitator 342, and the stirring speed of the pneumatic agitator 342 can be adjusted by adjusting the pressure of the compressed air to ensure that the materials are fully mixed.

[0024] Based on the above technical solution, flattening devices are provided on both sides of the scraper platform frame 2; The flattening device includes at least two pairs of clamping wheels 6, which correspond to the two sides of the film 8. The clamping wheels 6 are used to clamp the edges of the film 8. The flattening device makes the film 8 on both sides of the scraper platform frame 2 flat, which is more conducive to scraping and ensures that the adhesive surface is flat.

[0025] Based on the above technical solution, a conveyor 7 is also provided between the adhesive coating component 3 and the oven 4. The speed of the conveyor 7 is slightly greater than the film running speed. The conveyor 7 can support the film 8 and move it forward to avoid its downward deformation and eliminate the occurrence of scraper 21 marks, so as to ensure that the adhesive on its surface will not affect each other before curing.

[0026] Based on the above technical solution, the film unwinding device 1 includes an unwinding roller 11, which passes through the film roll. One end of the unwinding roller 11 is connected to a power source (generally a motor). The power source includes a magnetic powder clutch, which controls the rotational torque of the unwinding roller 11 to control the release tension of the film 8, achieving the goal of both stretching and preventing deformation. Furthermore, to prevent the adhesive material falling onto the film 8 from flowing in other directions, multiple reversing rollers 12 are also provided on the film unwinding device 1. The height of the exit end of the reversing rollers 12 is greater than or equal to the height of the doctor blade platform frame 2.

[0027] In the above, in order to keep the adhesive on the film 8 flat and prevent dripping, the doctor blade platform frame 2, the adhesive coating assembly 3, the oven 4, and the traction machine 5 are all at the same height, so that the film 8 is always kept horizontal.
