Description

Technical Field

[0001] The utility model relates to the technical field of cardboard film laminating devices, in particular to a film laminating device for cardboard processing. Background Technique

[0002] Film lamination has been widely used for surface binding and protection of book covers, picture albums, commemorative albums, postcards, product manuals, calendars, maps, etc. The adhesive is coated on the plastic film through a roller coating device, and after being pressed by a roller, the film is adhered to the surface of the cardboard. Then, the printed matter coated with the primer and the film are pressed together to form a film laminated product of paper-plastic combination. The composite cardboard also needs to be film laminated during the processing. However, when the existing film laminating device applies glue to the plastic film, the application is uneven, resulting in inconsistent glue thickness. In some places where there is more glue, the glue will drip onto the processing area, which not only causes waste but also makes the other side of the cardboard easily stick to the processing position. At the same time, during the handling of the cardboard, the surface will be contaminated with some dust and impurities, and the dust and impurities will be sealed between the cardboard and the film during the film lamination process, forming visible spots or protrusions, seriously affecting the aesthetics of the product and reducing the grade of the product.

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0022] Next, the present application will be described in detail in conjunction with the accompanying drawings and specific embodiments.

[0023] As Figures 1-7As shown in the figure, a film laminating device for cardboard processing includes: a processing table 1, two side plates 101 are fixedly connected to the top of the processing table 1, a conveyor 102 is arranged between the two side plates 101, a gantry a 103 is fixedly installed on the tops of the two side plates 101, a lifting rod 104 is fixedly installed on the gantry a 103, a film laminating roller 105 is fixedly installed at the bottom end of the lifting rod 104, a glue coating roller 106 is fixedly installed on one side of the film laminating roller 105, a gantry b 107 is fixedly installed on the tops of the two side plates 101, a glue recycling component, the glue recycling component is arranged on the glue coating roller 106 and is used for receiving the overflowing glue for reuse. The glue recycling component includes: a connecting rod 2, a square rod 201, a tightening bolt 202, a smoothing plate 203 and a material receiving frame 204, a cleaning component, the cleaning component is arranged on the gantry b 107 and is used for cleaning the dust and debris on the cardboard. The cleaning component includes: an air knife 3, an air duct 301, a dust collector 302, a mounting plate 303, a sliding rod 304 and a pressing roller 305.

[0024] Among them, a connecting rod 2 is fixedly connected between the inner walls of the glue coating roller 106. Two symmetrically arranged square holes are opened on the connecting rod 2. Threaded holes communicating with each other are opened on one side of the two square holes. Square rods 201 are respectively slidably connected inside the two square holes. Tightening bolts 202 are respectively screwed into the two threaded holes. A smoothing plate 203 is fixedly connected between the bottom ends of the two square rods 201. The bottom of the square rod 201 is arranged in an arc-shaped structure. A material receiving frame 204 is fixedly installed on one side of the film laminating roller 105. The material receiving frame 204 is located directly below the glue coating roller 106. A glue bucket 205 is fixedly installed on the partition of the processing table 1. A discharge port 206 is opened at the bottom end of the material receiving frame 204, and the inner bottom of the material receiving frame 204 is inclined downward towards the discharge port 206. A return pipe 207 is fixedly installed at the bottom end of the discharge port 206. The bottom end of the return pipe 207 is communicated with the inside of the glue bucket 205. A gear pump 4 is fixedly installed on one side of the glue bucket 205. The input end of the gear pump 4 is communicated with the inside of the glue bucket 205. The output end of the gear pump 4 is fixedly installed with a glue delivery pipe 401. An adhesive cylinder 402 is fixedly installed on the top of the film laminating roller 105. The top end of the glue delivery pipe 401 is communicated with the inside of the adhesive cylinder 402.

[0025] When applying glue, start the gear pump 4 to pump out the glue inside the glue bucket 205, and transport it through the glue delivery pipe 401 to the cavity inside the glue outlet cylinder 402, and then flow out from the glue outlet nozzle at the bottom and into the cavity inside the glue outlet cylinder 402. The film contacts the surface of the glue application roller 106. When the film laminating roller 105 laminates the film, pull the glue film to move, thereby driving the rotation of the glue application roller 106, so as to apply glue on the film. Use the leveling plate 203 to scrape the glue on the film to make the glue evenly distributed. When it is necessary to adjust the distance between the leveling plate 203 and the film, loosen the tightening bolt 202 to release the fixation of the square rod 201, and then move the square rod 201. The square rod 201 drives the leveling plate 203 to move, so as to achieve the effect of adjusting the distance from the film. After adjustment, tighten the tightening bolt 202 to fix the square rod 201, so as to control the thickness of the glue. The excess glue flows to both ends of the leveling plate 203 and then drops into the glue bucket 205. The glue converges at the feeding port 206 and flows back to the glue bucket 205 through the return pipe 207, so as to make the glue evenly applied, prevent the glue from dropping onto the conveyor 102, and recycle the overflowing glue to reduce waste.

[0026] Among them, an air knife 3 is provided inside the gantry b107. One side of the air knife 3 is fixedly connected with an air pipe 301. A dust collector 302 is fixedly installed on the partition of the processing table 1. The dust suction port of the dust collector 302 is connected with the air pipe 301. A mounting plate 303 is fixedly connected between the opposite inner walls of the gantry b107. Two slide bars 304 are respectively slidably connected to the two mounting plates 303. Pressure rollers 305 are respectively fixedly installed at the bottom ends of the two mounting plates 303. Fixed rings 306 are respectively fixedly connected to the outer parts of the two slide bars 304, and a movable ring 307 is slidably connected to the outer parts of the two slide bars 304. A spring 308 is connected between the fixed ring 306 and the movable ring 307. A threaded rod 5 is threadedly connected to the top of the gantry b107. The bottom end of the threaded rod 5 is rotatably connected to the air knife 3. The top end of the threaded rod 5 is fixedly connected with a handwheel 501. Guide grooves 502 are respectively opened on the opposite sides of the gantry b107. Guide blocks 503 are respectively fixedly connected to the opposite ends of the air knife 3. The two guide blocks 503 are respectively located inside the two guide grooves 502.

[0027] During film laminating, place the cardboard on the conveyor 102. Drive the cardboard to move through the conveyor 102. Then start the dust collector 302 to continuously suck air from the nozzles of the air knife 3. At this time, a suction force is generated at the nozzles of the air knife 3. When it moves under the gantry b107, it contacts the pressure roller 305 and then passes through from below. The two pressure rollers 305 can hold down the cardboard to prevent the air knife 3 from sucking up the cardboard. Under the elastic action of the spring 308, a force is applied downward to the pressure roller 305, making the cardboard fit tightly with the surface of the conveyor 102 and increasing the frictional force, so that the cardboard can still move driven by the conveyor 102. When the cardboard passes under the air knife 3, the dust and impurities on the surface to be film laminated are sucked away. The sucked dust is stored in the dustbin of the dust collector 302 along the air duct 301. By rotating the handwheel 501, the threaded rod 5 can be rotated with the gantry b107. The movement of the threaded rod 5 can drive the air knife 3 to move up and down. Since the guide blocks 503 at both ends of the air knife 3 are located in the two guide grooves 502, the air knife 3 is restricted to move only along the vertical direction of the guide grooves 502, so that the air knife 3 moves smoothly up and down at this time, thereby adjusting the distance between the air knife 3 and the cardboard.

[0028] Working principle:

[0029] When laminating, place the cardboard on the conveyor 102. Drive the cardboard to move through the conveyor 102. Then start the dust collector 302 to continuously suck air from the nozzles of the air knife 3. At this time, a suction force is generated at the nozzles of the air knife 3. When moving under the gantry b107, it contacts the pressure roller 305 and then passes through from below. The two pressure rollers 305 can hold down the cardboard to prevent the air knife 3 from sucking up the cardboard. Under the elastic action of the spring 308, a downward force is applied to the pressure roller 305, making the cardboard closely fit the surface of the conveyor 102 and increasing the friction force, so that the cardboard can still move driven by the conveyor 102. When the cardboard passes under the air knife 3, the dust and impurities on the surface to be laminated are sucked away. The sucked dust is stored in the dustbin of the dust collector 302 along the air duct 301. By rotating the handwheel 501, the threaded rod 5 can be screwed with the gantry b107. The movement of the threaded rod 5 can drive the air knife 3 to move up and down. Since the guide blocks 503 at both ends of the air knife 3 are located in the two guide grooves 502, the air knife 3 is restricted to move only along the vertical direction of the guide groove 502, so that the air knife 3 moves up and down smoothly at this time, and then the distance between the air knife 3 and the cardboard is adjusted. After cleaning, the cardboard flows under the gantry a103, and the film coated with glue is attached to the cardboard through the laminating roller 105. When applying glue, start the gear pump 4 to pump out the glue inside the glue bucket 205, and transport it through the glue delivery pipe 401 to the cavity inside the glue outlet cylinder 402, and then flow out from the glue outlet nozzle at the bottom and flow into the cavity inside the glue outlet cylinder 402. The plastic film contacts the surface of the glue coating roller 106. When laminating with the laminating roller 105, pull the glue film to move, thereby driving the glue coating roller 106 to rotate, so as to apply glue on the film. Use the leveling plate 203 to scrape the glue on the film to make the glue evenly distributed. When it is necessary to adjust the distance between the leveling plate 203 and the film, loosen the tightening bolt 202 to release the fixation of the square rod 201, and then move the square rod 201. The square rod 201 drives the leveling plate 203 to move, so as to achieve the function of adjusting the distance from the film. After adjustment, tighten the tightening bolt 202 to fix the square rod 201, so as to control the thickness of the glue. The excess glue flows to both ends of the leveling plate 203 and then drops into the glue bucket 205. The glue converges at the material outlet 206 and flows back to the glue bucket 205 through the return pipe 207, so as to make the glue evenly applied, prevent the glue from dropping onto the conveyor 102, and recycle the overflowing glue to reduce waste
