Description

Technical Field

[0001] This invention relates to the field of packaging film lamination technology, specifically to an automated lamination production line for multilayer packaging film lamination. Background Technology

[0002] Multilayer packaging film is a thin film structure that integrates multiple functional materials into one through a composite or co-extrusion process; it uses solvent-free adhesives, and the substrate is coated with adhesives, extruded and laminated, and then cooled and shaped.

[0003] However, in the production of multi-layer packaging film composites, it is inconvenient to quickly remove and replace the bonding substrate, coating substrate, and composite product. Furthermore, when applying adhesive to the coating substrate, it is impossible to reduce the impact of adhesive spillage on the surrounding environment. In dim environments, it is also inconvenient to observe the entire composite production process in real time. Summary of the Invention

[0004] The purpose of this invention is to provide an automated lamination production line for multilayer packaging film lamination, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An automated laminating production line for multi-layer packaging film lamination includes a fixed base, a support plate at the rear end of the upper surface of the fixed base, several lights on the top and sides of the support plate, three sets of rollers arranged sequentially from left to right at the middle of the front face of the support plate, with a right unwinding roller, a coating roller and a take-up roller arranged sequentially from left to right on the rollers, a collection box at the middle of the upper surface of the fixed base, a coating and adhesive-coating assembly above the collection box, a first guide roller near the left end of the front face of the support plate, a second guide roller near the middle of the support plate on one side of the coating roller, a heating roller above the coating and adhesive-coating assembly, a pressing roller above the heating roller, a cooling roller near the right end of the front face of the support plate, and an adhesive feeding assembly on the front face of the fixed base.

[0007] The coating and adhesive assembly includes an adhesive roller and a first steel roller symmetrically mounted below the adhesive roller. A second steel roller is provided above the adhesive roller, and a third guide roller is provided above the second steel roller. The adhesive roller, the first steel roller, and the second steel roller are all rotatably connected to a support plate via rotating shafts, and each corresponding rotating shaft is provided with a second gear, and the adjacent second gears mesh with each other.

[0008] The glue delivery assembly includes a glue storage tank and a sensing valve installed on one side of the glue storage tank. A delivery pump is installed on the top of the glue storage tank, and the output pipe of the delivery pump extends to the middle of the first steel roller.

[0009] Furthermore, the roller is rotatably connected to the support plate via a rotating shaft. Several arc-shaped grooves are provided on the outer wall of the roller. A limiting plate is provided at the front end of each roller. A fastening bolt is provided at the center of the front end of the limiting plate. The fastening bolt passes through the limiting plate and is threadedly connected to the end of the roller.

[0010] In this invention, the rear end of the limiting plate is inserted into the front end of the sleeve roller, and the fastening bolt is threaded into the end of the sleeve roller, so that the limiting plate limits the position of the end of the sleeve roller, thereby limiting the position of the roller sleeved in the middle of the sleeve roller and preventing it from coming off during use.

[0011] Specifically, the inner walls of the unwinding roller, coating roller, and take-up roller are all provided with arc-shaped blocks, and handle grooves are symmetrically opened on one end of each of them. The inner diameter of the unwinding roller, coating roller, and take-up roller is adapted to the outer diameter of the sleeve roller.

[0012] In this invention, the unwinding roller winds the base film to be coated, the coating roller winds the coating substrate to be bonded and adhered to the base film, and the take-up roller winds up the composite film to be completed by multi-layer packaging film lamination. The unwinding roller, coating roller, and take-up roller are respectively inserted and engaged with the corresponding sleeve rollers, and the arc-shaped block is inserted and engaged with the corresponding arc-shaped groove. With the engagement of the handle groove, it is convenient to take out or install the corresponding unwinding roller, coating roller, and take-up roller, providing a pulling force point.

[0013] Secondly, the first guide roller, the second guide roller, and the third guide roller are all rotatably connected to the support plate via a rotating shaft.

[0014] In this invention, the first guide roller lifts the base film discharged from the unwinding roller, the second guide roller lifts the coating substrate discharged from the coating roller, and the third guide roller guides the coated substrate after gluing to adhere to the base film and enter between the heating roller and the pressing roller for corresponding pressing and mating.

[0015] Specifically, a motor is provided on the rear end face of the support plate near the right end. The output shaft of the motor is coaxially connected to the rotating shaft of the right end roller through a coupling. A double extraction pipe is provided on one side of the sensing valve, and a single conveying pipe is provided on the other side. The conveying pipe is connected to the inside of the glue storage tank. The conveying pump draws glue from the inside of the glue storage tank and conveys it to the first steel roller through the discharge pipe.

[0016] In this invention, the motor is fixedly connected to the support plate by screws, and the motor is electrically connected to an external power source through wires. The control switch on the outer wall controls the output shaft to rotate, providing power for the overall operation and driving one of the rollers to rotate. The sensing valve controls the two portions of adhesive to be conveyed to enter the storage tank, and with the cooperation of the conveying pump, the mixed adhesive is drawn and conveyed to the first steel roller. An adhesive sensing structure is also provided above the first steel roller. When the adhesive level is lower than the sensing position, the conveying pump is started to convey the adhesive from the storage tank to the first steel roller. When the adhesive level is at the sensing structure, the conveying pump is stopped.

[0017] It should be noted that a first toothed belt is provided between the cooling roller and the sleeve roller located at the right end of the support plate. The first toothed belt is symmetrically provided with first toothed discs. One of the first toothed discs is connected to the rotating shaft of the sleeve roller, and the other first toothed disc is connected to the rotating shaft on the cooling roller. The first toothed belt meshes with the first toothed disc.

[0018] In this invention, the cooling roller is filled with coolant and comes into contact with the composite packaging film to reduce the heat of the packaging film and facilitate concentrated winding on the winding roller. The two first toothed discs are welded and fixed to the rotating shafts of the corresponding sleeve rollers and the rotating shafts on the cooling roller, respectively. With the cooperation of the first toothed belt, one of the sleeve rollers and the cooling roller rotate synchronously to cool the packaging bag and perform winding.

[0019] Furthermore, a second toothed belt is provided between the adhesive roller and the sleeve roller located at the right end of the support plate. The second toothed belt is symmetrically provided with second toothed discs. One of the second toothed discs is connected to the end of the rotating shaft of the sleeve roller, and the other second toothed disc is connected to the rotating shaft on the adhesive roller. The second toothed belt meshes with the second toothed disc.

[0020] In this invention, two second toothed discs are welded and fixed to the rotating shafts of the corresponding adhesive rollers and sleeve rollers, respectively. With the cooperation of the second toothed belt, the adhesive rollers and sleeve rollers rotate synchronously. With the meshing of multiple second gears, the adhesive rollers rotate synchronously with the first steel roller and the second steel roller.

[0021] The first steel roller is equipped with a corresponding adhesive spray nozzle between the two first steel rollers, which continuously sprays the adhesive liquid required for adhesive application. One of the first steel rollers is in close contact with the adhesive roller. The first steel roller applies the adhesive liquid adhering to its surface to the adhesive roller. The coating substrate passing above the adhesive roller is coated with the corresponding adhesive liquid. With the cooperation of the second steel roller, the coating substrate with the adhesive liquid is guided upward and discharged.

[0022] In addition, a third toothed belt is provided between the adhesive roller and the heating roller, and a third toothed disc is symmetrically provided on the third toothed belt. One of the third toothed discs is connected to the end of the shaft of the adhesive roller, and the other third toothed disc is connected to the shaft of the heating roller.

[0023] In this invention, two third toothed discs are welded and fixed to the shafts of the corresponding adhesive rollers and heating rollers, respectively. With the cooperation of the third toothed belt, the heating rollers and adhesive rollers can rotate synchronously.

[0024] Furthermore, the heating roller is hollow inside, and a heating rod is inserted into the end of the heating roller. The heating rod is fixedly connected to the top of the support plate by screws, and the heating roller and the pressing roller are connected by two first gears meshing together.

[0025] In this invention, the heating rod is electrically connected to an external power source via a wire, and a control switch is provided on the outer wall of the heating rod. When the heating rod is turned on, the heating temperature is in the range of 40-60 degrees Celsius, thereby heating the heating roller and maintaining it within the range of 40-60 degrees Celsius. Under the meshing of the two first gears, the heating roller and the pressing roller rotate synchronously in opposite directions, pressing and bonding the coated substrate with adhesive and the base film that pass through the middle to form a composite combination.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. This invention uses three sleeve rollers, with corresponding limiting plates and fastening bolts, to fix the positions of the unwinding roller, coating roller, and take-up roller mounted on the sleeve rollers. In the coating and adhesive assembly, the adhesive roller is bonded to one of the first steel rollers, and the adhesive to be bonded is sprayed between the two first steel rollers. The first steel roller is bonded to the surface of the adhesive roller. With the cooperation of the heating roller and the pressing roller, the coating substrate with adhesive is bonded and pressed to the base film for composite pressing. After being cooled by the cooling roller, it is finally collected in the take-up roller. The limiting plate is easy to disassemble and the unwinding roller, coating roller, and take-up roller can be quickly disassembled and replaced.

[0028] 2. This invention provides a power source for the entire system by setting a motor. With the cooperation of the first toothed belt and the first toothed disc, one of the sleeve rollers and the cooling roller rotate synchronously. With the cooperation of the second toothed belt and the second toothed disc, the adhesive roller and the sleeve roller rotate synchronously. With the cooperation of the third toothed belt and the third toothed disc, the heating roller and the adhesive roller rotate synchronously.
