Description

Technical Field

[0001] This utility model relates to the field of membrane lamination technology, and more specifically, to a rapid membrane lamination device. Background Technology

[0002] Film lamination equipment is primarily used to bond labels and films together, and is commonly found in the packaging industry, particularly in the food and beverage sectors, for producing various types of packaged products. During the packaging process, the label and film are fed into the lamination equipment, where a series of heating, pressure, and cooling processes activate the adhesive between them, firmly bonding them together. This equipment plays a crucial role in modern packaging production.

[0003] Chinese Patent Announcement No. CN219407283U discloses an anti-counterfeiting label pressing device. This solution, through the coordinated use of a pressure roller, a pushing cylinder, a lead screw, a reciprocating motor, and a connecting frame, can apply pressure to the label during pressing, thereby making the pressed label more compact. The pressure roller acts to press the label, the pushing cylinder generates pressure, the lead screw drives the threaded sleeve to move, the reciprocating motor generates driving force to rotate the lead screw, and the connecting frame drives the pressure roller to move, thus improving the practicality of the device and meeting the user's needs.

[0004] During the lamination process, the film and label paper need to be completely overlapped before the film layers are laminated. The device in the above scheme does not have a corresponding limiting and alignment device, which makes it easy for the film and label paper to become misaligned during the lamination process. Misalignment will lead to weak adhesion between the label and the film, and may even lead to insufficient adhesion in some areas or complete detachment, affecting the packaging quality of the product.

[0005] Therefore, a rapid film lamination device is proposed to address the above problems. Utility Model Content

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0039] Please see Figures 1-5 A rapid film pressing device includes an outer frame 1, a pressing roller 7, a heating roller 10, and a rotating roller 9. The two ends of the pressing roller 7 are rotatably connected to the two sides inside the outer frame 1, and the two ends of the heating roller 10 are rotatably connected to the two sides inside the outer frame 1. A limiting component 8 is provided inside the outer frame 1. The limiting component 8 includes a roller body 81. Two limiting discs 83 are provided outside the roller body 81. The limiting discs 83 protrude from the outer surface of the roller body 81 to limit the label paper. The roller body 81 is provided with a scale.

[0040] The device in this scheme is mainly used for laminating label paper. Inside the outer frame 1, a pressing roller 7, a rotating roller 9, a heating roller 10, and a limiting component 8 are rotatably mounted. The heating roller 10 and the limiting component 8 mainly serve as guides, while the pressing roller 7 and the rotating roller 9 perform the pressing function. Outside the outer frame 1, a film layer roller 6 and a label paper roller 13 are also provided. The film layer roller 6 is mainly used to hold the film, while the label paper roller 13 is used to hold the label paper. The label paper and film are drawn out from the label paper roller 13 and the film layer roller 6 respectively, then converge and adhere together on the heating roller 10. After passing around the limiting component 8, they are limited and corrected by two limiting discs 83 on the roller body 81, and then enter the pressing roller 7 and the rotating roller 9 for pressing. Through the precise control of the limiting component 8, product damage or defective products caused by misalignment can be effectively avoided, reducing the scrap rate and thus saving materials and production costs.

[0041] Please see Figure 1 and Figure 2 One end of the rotating roller 9 is rotatably connected to the inner wall of the outer frame 1, and the other end of the rotating roller 9 extends through the side wall of the outer frame 1 to the outside and is fixedly installed with a passive pulley 5.

[0042] A motor 11 is fixedly installed on the inner bottom of the outer frame 1. The output end of the motor 11 extends through the side wall of the outer frame 1 to the outside and is fixedly installed with a drive pulley 4. The passive pulley 5 and the drive pulley 4 are connected by a belt 3 to drive the rotating roller 9 to rotate actively. The rotating roller 9 is located below the pressing roller 7, and a gap is provided between the rotating roller 9 and the pressing roller 7 to allow the label paper to pass through.

[0043] A film layer roller 6 is rotatably connected to the outer end of the outer frame 1, a label paper roller 13 is rotatably connected to the outer end of the outer frame 1, the label paper roller 13 is located below the film layer roller 6, and a take-up roller 2 is rotatably connected to the outer end of the outer frame 1.

[0044] A motor 12 is fixedly installed at the outer end of the outer frame 1. The output end of the motor 12 is connected to one end of the take-up roller 2 to drive the take-up roller 2 to rotate and take up the label paper.

[0045] In this design, both the film roller 6 and the label roller 13 are rotatably mounted on the outside of the outer frame 1, but they can also be removed for easy loading and unloading. The heating roller 10 serves not only as a guide but also as a heating element. Due to the small thickness of the film, the heating roller 10 contains a heating element, usually a resistance wire or an electric heating tube, which is heated by current to raise the surface temperature to the required operating temperature. When the film passes through the heating roller 10, heat is transferred from the heating roller 10 to the label paper and the film, causing them to heat up rapidly. Therefore, by heating and then pressing, the film can be bonded more firmly to the label paper.

[0046] When the film and label paper overlap on the heating roller 10, they are heated. Then, the label paper and film, after passing the limiting component 8, enter the gap between the pressing roller 7 and the rotating roller 9. The height of the pressing roller 7 is adjustable and can be controlled by a drive device such as a connected cylinder, allowing it to be adjusted according to the label thickness. The rotating roller 9, located below the pressing roller 7, is rotatable, thus conveying the label forward through friction. One end of the rotating roller 9 is rotatably connected to the side wall of the outer frame 1, while the other end, while rotatably connected, also penetrates through the outer frame 1. The side wall of frame 1 extends to the outside and is fixedly installed with a passive pulley 5. Inside the bottom of the outer frame 1, a motor 11 is fixed. The output end of motor 11 also extends to the outside through the side wall of the outer frame 1 and is fixed with a driving pulley 4. A belt 3 is wound around the outside of both the passive pulley 5 and the driving pulley 4. The driving pulley 4 and the passive pulley 5 are connected by the belt 3. When motor 11 rotates, the driving pulley 4 drives the passive pulley 5 to rotate. At this time, the rotating roller 9 will rotate, thereby conveying the pressed label out.

[0047] Motor 2 12 is fixedly installed at the outer end of the outer frame 1, while take-up roller 2 is rotatably installed at the outer end of the outer frame 1. One end of take-up roller 2 is connected to the output end of motor 2 12, so that motor 2 12 can drive take-up roller 2 to rotate. Through cooperation with rotating roller 9, the pressed label can be rolled up. It is worth mentioning that take-up roller 2 is also a detachable connection method, which makes it easy to remove.

[0048] Please see Figures 3-5The limiting component 8 also includes a bidirectional screw 85. Both ends of the roller body 81 are fixedly installed with rotating shafts 84. The roller body 81 is rotatably installed inside the outer frame 1 through the two rotating shafts 84. The bidirectional screw 85 is located inside the roller body 81. One end of the bidirectional screw 85 is rotatably connected to one of the rotating shafts 84, and the other end of the bidirectional screw 85 extends through the other rotating shaft 84 to the outside and is fixedly installed with a rotating knob 86.

[0049] The limiting plate 83 includes a limiting ring 831, a fixed plate 832, and multiple connecting rods 833. The fixed plate 832 is fixedly installed inside the limiting ring 831 through multiple connecting rods 833. The fixed plate 832 is threadedly connected to the bidirectional screw 85. Multiple movable grooves 82 are opened at the outer end of the roller body 81. Multiple connecting rods 833 pass through multiple movable grooves 82 respectively. The limiting ring 831 slides outside the roller body 81 through multiple connecting rods 833.

[0050] The limiting component 8 in this design is mainly used for limiting. The roller body 81 is hollow inside, and rotating shafts 84 are fixed at both ends of the roller body 81. Bearings are installed on the outer ends of the rotating shafts 84, allowing the roller body 81 to be rotatably mounted on the inner side of the outer frame 1 via the two rotating shafts 84. The inner side of the bidirectional screw 85 is provided with a bidirectional screw 85. One end of the bidirectional screw 85 is rotatably connected to one of the rotating shafts 84, while the other end of the bidirectional screw 85 passes through the other rotating shaft 84, exposing one end of the bidirectional screw 85. A rotating knob 86 is fixed to the outer end of the bidirectional screw 85, allowing the bidirectional screw 85 to be rotated by rotating the rotating knob 86. The bidirectional screw 85 has two sets of threads in opposite directions, and the two limiting discs 83 are threadedly connected to the bidirectional screw 85. When it is necessary to adjust the distance between the two limiting discs 83, the bidirectional screw 85 can be rotated by turning the rotating knob 86. At this time, the two limiting discs 83 will move in opposite directions to adjust the distance, so that it can be used for labels of different widths. Through the limiting blocking of the limiting discs 83, when the label paper and film are on the roller 81, they can be clamped by the two limiting discs 83 to prevent misalignment. Correct alignment of the label paper and film can ensure the consistency and integrity of the product appearance, avoid appearance or adhesion quality problems caused by misalignment, and thus improve product quality.

[0051] The aforementioned limiting plate 83 mainly consists of a limiting ring 831, a fixed plate 832, and four connecting rods 833. The limiting ring 831 and the fixed plate 832 are concentrically arranged. The fixed plate 832 and the limiting ring 831 are connected together by the four connecting rods 833. The fixed plate 832 is threadedly connected to the bidirectional screw 85. Four movable grooves 82 are opened on the outside of the roller body 81. The connecting rods 833 pass through the movable grooves 82 and slide with them. The limiting ring 831 also surrounds the outer surface of the roller body 81 and slides on the outside of the roller body 81 driven by the fixed plate 832. It is worth mentioning that each movable groove 82 is marked with a scale, mainly used to indicate the distance between the two limiting rings 831, so that the user can easily adjust it.

[0052] Working principle: When using this device, first place the film on the film roller 6 and the label on the label roller 13. Then, manually adjust the limiting component 8 by rotating the rotary knob 86 to make the bidirectional screw 85 rotate. At this time, the two limiting discs 83 will move in opposite directions to adjust the spacing according to the label width. By limiting the blocking of the limiting discs 83, when the label and film are on the roller 81, they can be clamped by the two limiting discs 83 to prevent them from being misaligned.

[0053] At this point, the label paper and film can be manually drawn out from the label paper roller 13 and film layer roller 6 respectively, then joined and attached together on the heating roller 10, and then passed around the limiting component 8, and can be limited and corrected by the two limiting discs 83 on the roller body 81, and then enter the pressing roller 7 and rotating roller 9 for pressing, and then wound on the winding roller 2. At this point, the motor 11 and motor 22 can be started to automatically press and wind them up.
