Description

Technical Field

[0001] This utility model relates to flexible packaging lamination equipment, and more particularly to a flexible packaging flexographic transfer coating lamination equipment. Background Technology

[0002] Coating and laminating equipment involves applying adhesive to a film material and then laminating two or more layers of film together. Because different film materials vary in material composition, surface characteristics, thickness, and uniformity, the requirements for adhesive adsorption and coating effects also differ. Therefore, the amount of adhesive used varies depending on the film material being coated. However, existing coating and laminating equipment generally uses a fixed adhesive application method. When dealing with highly hydrophilic film materials, traditional equipment may result in insufficient adhesive supply, leading to weak adhesion; while when handling hydrophobic film materials, excessive adhesive buildup may cause defects such as flow marks and bubbles. This limitation in adhesive application control directly results in the difficulty of achieving an ideal uniform distribution of adhesive on the film surface, leading to localized areas of excessively thick or thin adhesive. Uneven adhesive coating not only seriously affects the uniformity of the membrane material, causing the thickness deviation of the composite membrane material to exceed the standard range, but also negatively affects the transparency of the membrane material, causing problems such as turbidity and increased haze in the composite membrane material. This greatly reduces the product quality and yield of the composite membrane material, and increases the production cost and resource waste of enterprises. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a flexible transfer coating and laminating equipment for flexible packaging. This flexible transfer coating and laminating equipment can freely control the amount of glue according to the coating requirements of different film materials, which can ensure the uniformity and transparency of the film material coating, improve the flatness of the film material, and effectively reduce the amount of glue applied.

[0004] To solve the above technical problems, the following technical solution is adopted:

[0005] A flexible packaging flexographic transfer coating and laminating equipment includes a frame, a traction mechanism, a first unwinding mechanism, a coating mechanism, a drying mechanism, a laminating mechanism, and a rewinding mechanism arranged sequentially along the conveying direction of the traction mechanism, and a second unwinding mechanism arranged in front of the laminating mechanism along the conveying direction of the traction mechanism. The coating mechanism includes an adhesive storage device, a metering dip roller, a metering anilox roller, a transfer roller, a coating pressure roller, a rotation drive mechanism capable of driving the metering dip roller to rotate, and a first lifting drive mechanism capable of driving the coating pressure roller to rise and fall. The adhesive storage device, the rotation drive mechanism, and the first lifting drive mechanism are respectively mounted on the frame. The metering dip roller, the metering anilox roller, and the transfer roller are rotatably mounted on the frame. The metering dip roller corresponds to the position of the adhesive storage device, and the metering anilox roller is in contact with the roller surface of the metering dip roller. The coating mechanism also includes a translation mechanism capable of driving the transfer roller away from or towards the metering anilox roller, and the coating pressure roller corresponds to the position of the transfer roller.

[0006] When the above-mentioned flexible packaging flexographic transfer coating and laminating equipment coats and presses the film material, the first film material released from the first unwinding mechanism is conveyed by the traction mechanism; the rotation drive mechanism drives the metering dip roller to rotate, so that the metering dip roller is dipped in glue from the glue storage device, and the glue is transferred to the transfer roller in sequence through the metering anilox roller. The transfer roller can be moved by the translation mechanism to adjust the pressure between the transfer roller and the metering anilox roller, thereby adjusting the amount of glue transferred to the transfer roller; then the first lifting drive mechanism drives the coating pressure roller to press down, pressing the first film material onto the transfer roller and making it contact the transfer roller, so that the glue is transferred to the surface of the first film material; the coated first film material is conveyed to the drying mechanism, and after drying, it is laminated with the second film material released from the second unwinding mechanism in the laminating mechanism; finally, the laminated film material is wound up by the winding mechanism. This flexible transfer coating laminating equipment for flexible packaging allows for free adjustment of the amount of adhesive transferred to the transfer roller according to the needs of different film materials when applying adhesive. It can easily control the amount of adhesive used in the film material, ensuring the transparency and uniformity of the coating for different products, effectively saving adhesive, and guaranteeing the lamination quality. Furthermore, it has a simple structure and is easy to adjust.

[0007] The aforementioned traction mechanism typically consists of multiple guide rollers, which are arranged sequentially according to the required traction direction; the aforementioned composite mechanism typically consists of two pressing rollers that press against each other.

[0008] In a preferred embodiment, the translation mechanism includes a guide groove formed on the frame, the guide groove being arranged in a left-right direction, and the transfer roller being movably disposed in the guide groove. In the aforementioned left-right direction, the position furthest from the metering anilox roller is on the left, and the position closest to the metering anilox roller is on the right. Depending on the adhesive application requirements, the transfer roller can be moved left and right along the guide groove, thereby adjusting the pressure between the transfer roller and the metering anilox roller.

[0009] In a further preferred embodiment, the translation mechanism further includes a bearing, a translation seat, and a drive mechanism capable of driving the translation seat to translate. The drive mechanism is mounted on the frame. The translation seat is movably disposed in the guide groove. The transfer roller is rotatably mounted on the translation seat via the bearing. The outer ring of the bearing is connected to the translation seat, and the inner ring of the bearing is connected to the transfer roller. The drive mechanism can be electrically driven, such as a ball screw and nut mechanism, or it can be manually adjusted, such as a combination of a handwheel and a lead screw. During adjustment, the translation seat is driven to translate along the guide groove by the drive mechanism, thereby adjusting the position of the transfer roller.

[0010] In a preferred embodiment, the adhesive storage device includes an adhesive tank and a second lifting drive mechanism capable of driving the adhesive tank to rise and fall. The second lifting drive mechanism is mounted on the frame, and the metering dip roller extends into the adhesive tank. The position of the adhesive tank can also be adjusted by the second lifting drive mechanism, thereby adjusting the dip depth of the metering dip roller and further controlling the amount of adhesive used.

[0011] Both the first and second lifting drive mechanisms mentioned above can use cylinders.

[0012] In a preferred embodiment, the drying mechanism includes multiple ovens connected end-to-end, with the drying paths of each oven forming an upward-arched arc. The first unwinding mechanism and coating mechanism are located on one side of the drying mechanism, while the second unwinding mechanism, laminating mechanism, and rewinding mechanism are located on the other side. This arched arc design extends the drying path while minimizing floor space required.

[0013] In the preferred embodiment, both the first and second unwinding mechanisms employ a tilting unwinding machine, and the winding mechanism employs a tilting winding machine. Both the tilting unwinding and tilting winding machines can utilize existing equipment; for example, the tilting unwinding machine can be an automatic film splicing device with publication number CN220684182U, and the tilting winding machine can be a tilting winding machine with publication number CN116443662A. Using tilting unwinding and winding machines allows for continuous processing without stopping the machine, improving production efficiency.

[0014] The beneficial effects of this utility model are as follows: This flexible transfer coating and laminating equipment for flexible packaging can freely control the amount of glue used according to the glue application requirements of different film materials, which can ensure the uniformity and transparency of the glue application, improve the flatness of the film material, and effectively reduce the amount of glue applied.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0019] When the above-mentioned flexible packaging flexographic transfer coating and laminating equipment coats and presses the film material, the first film material released from the first unwinding mechanism 3 is conveyed by the traction mechanism 2; the rotation drive mechanism 406 drives the metering dip roller 402 to rotate, so that the metering dip roller 402 is dipped in glue from the glue storage device 401, and the glue is transferred to the transfer roller 404 in sequence through the metering anilox roller 403. The transfer roller 404 and the metering anilox roller 403 can be adjusted by moving the transfer roller 404 through the translation mechanism. The pressure of the first film material is adjusted to control the amount of adhesive transferred to the transfer roller 404. Then, the first lifting drive mechanism 407 drives the coating roller 405 to press down, pressing the first film material onto and into contact with the transfer roller 404, transferring the adhesive to the surface of the first film material. The coated first film material is then conveyed to the drying mechanism 5 and, after drying, is laminated with the second film material released from the second unwinding mechanism 8 in the laminating mechanism 6. Finally, the laminated film material is wound up by the winding mechanism 7. This flexible packaging transfer coating laminating equipment allows for free adjustment of the amount of adhesive transferred to the transfer roller 404 according to the needs of different film materials. This facilitates control of the adhesive amount, ensuring both the transparency and uniformity of the coating for different products, effectively saving adhesive, guaranteeing lamination quality, and offering a simple structure and convenient adjustment.

[0021] The translation mechanism includes a guide groove 408 formed on the frame 1, which is arranged in a left-right direction. The transfer roller 404 is movably disposed in the guide groove 408. In the left-right direction, the position furthest from the metering anilox roller 403 is on the left, and the position closest to the metering anilox roller 403 is on the right. According to the glue application requirements, the transfer roller 404 can be moved left and right along the guide groove 408, thereby adjusting the degree of pressure between the transfer roller 404 and the metering anilox roller 403.

[0022] The translation mechanism also includes bearings, a translation seat, and a drive mechanism (not shown in the figure) capable of driving the translation seat to move.

The outer ring of the bearing is connected to the translation seat, and the inner ring of the bearing is connected to the transfer roller 404. The drive mechanism can be electrically driven, such as a ball screw and nut mechanism, or manually adjusted, such as a combination of a handwheel and a lead screw. During adjustment, the drive mechanism drives the translation seat to move along the guide groove 408, thereby adjusting the position of the transfer roller 404.

[0023] The glue storage device 401 includes a glue tank 4011 and a second lifting drive mechanism 4012 capable of driving the glue tank 4011 to rise and fall. The second lifting drive mechanism 4012 is mounted on the frame 1, and the metering glue-dipping roller 402 extends into the glue tank 4011. The position of the glue tank 4011 can also be adjusted by the second lifting drive mechanism 4012, thereby adjusting the glue-dipping depth of the metering glue-dipping roller 402 and further controlling the amount of glue used.

[0024] Both the first lifting drive mechanism 407 and the second lifting drive mechanism 4012 mentioned above can use cylinders.

[0025] The drying mechanism 5 includes multiple ovens 501 connected end to end, and the drying paths of each oven 501 together form an upward-arching arc. The first unwinding mechanism 3 and the coating mechanism 4 are located on one side of the drying mechanism 5, and the second unwinding mechanism 8, the compounding mechanism 6, and the winding mechanism 7 are located on the other side of the drying mechanism 5. The arched arc design can extend the drying path while minimizing the footprint.

[0026] Both the first unwinding mechanism 3 and the second unwinding mechanism 8 employ a tilting-type unwinding machine, and the winding mechanism 7 employs a tilting-type winding machine. Both the tilting-type unwinding and winding machines can utilize existing equipment.
