Description

Technical Field

[0001] This utility model relates to the field of adhesive sheet processing technology, and specifically to an adhesive sheet composite device. Background Technology

[0002] Composite laminated sheets are typically thicker than single-layer laminated sheets and offer superior corrosion resistance and mechanical strength. Currently, composite laminated sheet production usually involves bonding multiple layers of thin sheets together with adhesive and then curing them under pressure and heat in a mold. This method relies on additional adhesives, cannot achieve continuous production, and is inefficient. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a glue-sheet lamination device that enables glue-free and continuous glue-sheet lamination.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A composite sheet device is characterized in that it includes a second conveyor belt, a first pressure roller, a third conveyor belt, and a second pressure roller arranged sequentially along the feeding direction. A heating module is provided above the second conveyor belt, and an adsorption lifting module is provided on the third conveyor belt. The adsorption lifting module includes a suction cup bracket, a driving mechanism for driving the suction cup bracket to move up and down, and a plurality of suction cups installed on the suction cup bracket, all of which face directly downward.

[0006] Preferably, the heating module is a heating and insulation box covering the second conveyor belt. The heating and insulation box has an inlet and an outlet for the composite adhesive sheet to pass through. Multiple evenly arranged heating tubes are installed on the inner upper surface of the heating and insulation box to provide a uniform heating environment and ensure that the adhesive fluidization on the surface of the adhesive sheet is uniform and consistent.

[0007] Preferably, the distance between the heating tube and the conveyor belt is 200~500mm to optimize heat transfer efficiency and avoid overheating damage or insufficient heating of the rubber sheet.

[0008] Preferably, the internal temperature of the heating module is 60~80℃, which enables the adhesive sheet surface to produce suitable viscosity and flow, promotes the subsequent lamination process, and maintains the stability of the internal properties of the adhesive sheet.

[0009] Preferably, the first pressure roller includes a first upper roller and a first lower roller. The first upper roller is connected to a first adjustment mechanism for adjusting the gap between the first upper roller and the first lower roller, which facilitates the adaptation to rubber sheets of different thicknesses and ensures the pre-flattening effect to reduce air bubbles.

[0010] Preferably, the second pressure roller includes a second upper roller and a second lower roller. The second upper roller is connected to a second adjustment mechanism for adjusting the gap between the second upper roller and the second lower roller, which can adapt to different thicknesses of rubber sheets, flexibly adjust the pressure, and achieve full extrusion and degassing of the composite rubber sheet.

[0011] Preferably, the suction cup is controlled by an electrical signal to perform the adsorption or release action, thereby achieving automated operation and improving production efficiency and reliability.

[0012] Preferably, the system also includes a control system and an infrared sensor. The infrared sensor is set at any position on the conveyor belt to detect the position signal of the adhesive sheet to be laminated. The control system is connected to the infrared sensor and the adsorption lifting module. The system can automatically detect the position signal of the adhesive sheet by the infrared sensor and control the timing of the adsorption lifting module to ensure accurate lamination and alignment.

[0013] Preferably, a fourth conveyor belt for feeding is provided downstream of the second pressure roller to support a continuous feeding process and improve overall production efficiency.

[0014] Preferably, a first conveyor belt for feeding is also provided upstream of the second conveyor belt, which can be combined with an external feeding device to achieve automatic feeding and enhance production continuity and stability.

[0015] This invention enables continuous production of composite adhesive sheets, significantly improving efficiency and reducing costs. The heating module enables the adhesive sheet surface to become self-adhesive, eliminating the need for additional adhesives and simplifying the process. The adsorption and lifting module, combined with the control system, ensures precise stacking of multiple layers of adhesive sheets, avoiding misalignment. The two sets of pressure rollers effectively remove any air bubbles that may be generated, improving the production quality and consistency of the composite adhesive sheets.

[0021] A heating and insulation box 7 is installed above the second conveyor belt 2. The heating and insulation box 7 covers the second conveyor belt 2 and has openings at the inlet and outlet of the second conveyor belt 2 for the passage of the adhesive sheet. Multiple evenly arranged heating tubes are installed on the upper surface inside the heating and insulation box 7, with a distance of 350 mm between the heating tubes and the conveyor belt, and a heating temperature between 60 and 80°C. An infrared sensor 9 is installed at the end of the second conveyor belt 2, near the inlet of the first pressure roller 5, to detect the position signal of the adhesive sheet to be laminated.

[0022] The first pressure roller 5 includes a first upper roller and a first lower roller, with the roller gap height of the first pressure roller 5 slightly higher than the upper surface of the conveyor belt. The first upper roller is connected to a first adjusting mechanism, which is used to adjust the roller gap distance between the first upper roller and the first lower roller. In the lamination of the rubber sheet, the roller gap distance of the first pressure roller 5 is generally controlled between 3 and 6 mm. The adjusting mechanism is a pneumatic cylinder or a hydraulic cylinder.

[0023] An adsorption lifting module 8 is installed above the third conveyor belt 3. The adsorption lifting module 8 includes a suction cup bracket, a drive mechanism, and multiple suction cups mounted on the suction cup bracket. The suction cups are controlled by electrical signals to adsorb or release. All suction cups face directly downwards and are located in the same plane. The suction cups are used to adsorb the adhesive sheet to be laminated, which is being conveyed to the third conveyor belt 3. The drive mechanism is connected to the suction cup bracket and is used to drive the suction cup bracket to move up and down vertically. The infrared sensor 9 is connected to the equipment's control system. Based on the adhesive sheet position signal detected by the infrared sensor 9 and the running speed of the conveyor belt, the control system calculates the time it takes for the adhesive sheet to reach the area directly below the adsorption lifting module 8, and accordingly precisely controls the timing of the adsorption lifting module 8's operation.

[0024] The second pressure roller 6 includes a second upper roller and a second lower roller, with the roller gap height slightly higher than the upper surface of the conveyor belt. The second upper roller is connected to a second adjusting mechanism, which is used to adjust the roller gap distance between the second upper roller and the second lower roller. In the lamination of the rubber sheet, the roller gap distance of the second pressure roller 6 is generally controlled between 5 and 12 mm.

[0025] The first pressure roller includes an upper roller and a lower roller, with the roller gap height slightly higher than the upper surface of the conveyor belt. The upper roller is connected to a first adjusting mechanism, which is used to adjust the roller gap distance between the upper and lower rollers. In the lamination of the rubber sheet, the roller gap distance of the first pressure roller is generally controlled between 3 and 6 mm. The adjusting mechanism is a pneumatic cylinder or a hydraulic cylinder.

[0026] The first pressure roller 5 includes a first upper roller and a first lower roller, with the roller gap height of the first pressure roller 5 slightly higher than the upper surface of the conveyor belt. The first upper roller is connected to a first adjusting mechanism, which is used to adjust the roller gap distance between the first upper roller and the first lower roller. In the lamination of the rubber sheet, the roller gap distance of the first pressure roller 5 is generally controlled between 3 and 6 mm. The adjusting mechanism is a pneumatic cylinder or a hydraulic cylinder.

[0027] An adsorption lifting module 8 is installed above the third conveyor belt 3. The adsorption lifting module 8 includes a suction cup bracket, a drive mechanism, and multiple suction cups mounted on the suction cup bracket. The suction cups are controlled by electrical signals to adsorb or release. All suction cups face directly downwards and are located in the same plane. The suction cups are used to adsorb the adhesive sheet to be laminated, which is being conveyed to the third conveyor belt 3. The drive mechanism is connected to the suction cup bracket and is used to drive the suction cup bracket to move up and down vertically. The infrared sensor 9 is connected to the equipment's control system. Based on the adhesive sheet position signal detected by the infrared sensor 9 and the running speed of the conveyor belt, the control system calculates the time it takes for the adhesive sheet to reach the area directly below the adsorption lifting module 8, and accordingly precisely controls the timing of the adsorption lifting module 8's operation.

[0028] The second pressure roller 6 includes a second upper roller and a second lower roller, with the roller gap height slightly higher than the upper surface of the conveyor belt. The second upper roller is connected to a second adjusting mechanism, which is used to adjust the roller gap distance between the second upper roller and the second lower roller. In the lamination of the rubber sheet, the roller gap distance of the second pressure roller 6 is generally controlled between 5 and 12 mm.

[0029] The specific implementation process of this utility model is as follows:

[0030] S1: Place multiple composite adhesive sheets onto the first conveyor belt 1 sequentially at certain time intervals;

[0031] S2: The first conveyor belt 1 transports the composite adhesive sheet to the second conveyor belt 2. Under the heating action of the heating and heat preservation box 7, the surface of the composite adhesive sheet becomes fluidized. When the composite adhesive sheet reaches the end of the second conveyor belt 2, the infrared sensor 9 detects the position signal of the adhesive sheet and sends it to the control system. The control system calculates the time it takes for the adhesive sheet to move to the position directly below the adsorption and lifting module 8 based on this signal and the speed of the conveyor belt.

[0032] S3: The second conveyor belt 2 conveys the surface-fluidized adhesive sheet to be laminated to the first pressure roller 55. The first pressure roller pre-flattens the adhesive sheet to be laminated to avoid air bubbles at the joint when laminated with other adhesive sheets.

[0033] S4: After the composite sheet passes through the first pressure roller 5, it is conveyed to the third conveyor belt 3. If the adsorption lifting module 8 does not adsorb the sheet, the calculation result in step S2 of the system is controlled. When the sheet moves to the position directly below the adsorption lifting module 8, the drive mechanism drives the suction cup bracket and suction cup to move down. After the suction cup adsorbs the composite sheet, it moves up and lifts the composite sheet above the third conveyor belt 3. The distance between the adsorbed composite sheet and the third conveyor belt 3 should be greater than the thickness of the next composite sheet. If the adsorption lifting module 8 has adsorbed the sheet, the calculation result in step S2 of the system is controlled. When the sheet moves to the position directly below the adsorption lifting module 8, the drive mechanism drives the suction cup bracket and suction cup to move down. After the suction cup releases the adsorbed composite sheet, it moves up and the two composite sheets are bonded together by the adhesiveness of the sheet surface to form a composite sheet.

[0034] S5: The third conveyor belt 3 transports the composite sheet to the second pressure roller 6, which squeezes and exhausts the composite sheet before transporting it to the fourth conveyor belt 4.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
