Description
Technical Field
[0001] This utility model relates to the field of solventless laminating machine technology, and in particular to a solventless laminating machine for sheets. Background Technology
[0002] In the sheet processing industry, laminating machines are indispensable equipment. They are mainly used to combine two or more sheets through specific processes to form composite materials with new properties. Traditional laminating machines mostly use solvent-based adhesives for lamination. However, this method not only causes environmental pollution problems, but also requires a long drying time during the lamination process, affecting production efficiency.
[0003] In recent years, with increasing environmental awareness and technological advancements, solvent-free lamination technology has gradually emerged. Solvent-free laminating machines achieve rapid, efficient, and environmentally friendly lamination of sheets using solvent-free adhesives. However, existing solvent-free laminating machines often encounter some problems during the lamination process, such as poor lamination results and the formation of bubbles or delamination in the laminated sheets. These problems not only affect the quality of the laminated sheets but also limit the further promotion and application of solvent-free lamination technology. Utility Model Content
[0004] The purpose of this invention is to solve the shortcomings of existing technologies, such as poor composite effect and easy occurrence of bubbles or delamination in the composited sheets, and to propose a solvent-free sheet laminating machine.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A solventless sheet laminating machine includes a laminating machine body, a rectangular frame fixedly connected to one side of the laminating machine body, a first conveyor belt and a second conveyor belt arranged inside the laminating machine body, the second conveyor belt being located below the rectangular frame, the second conveyor belt consisting of two parallel conveyor belts, the first conveyor belt being located on the top side of the rectangular frame, a sheet body being arranged inside the rectangular frame, and a laminating component for laminating the sheet body being arranged inside the rectangular frame.
[0007] A first fixing plate is fixedly connected to one side of the inner wall of the composite machine body, and a pushing component for pushing two sheet bodies to fit together is provided on one side of the first fixing plate.
[0008] A first rectangular hole is provided on one side of the main body of the laminating machine, and a pressing component for pressing the sheet body again is provided inside the first rectangular hole.
[0009] In one possible design, the composite component includes a plurality of circular holes formed in the inner wall of a rectangular frame, the circular holes communicating with the cavity of the rectangular frame, an air extraction hole formed on one side of the rectangular frame communicating with the cavity of the rectangular frame, and a protective frame fixedly connected to the top side of the rectangular frame.
[0010] In one possible design, the actuating assembly includes a servo motor fixedly connected to one side of a first fixed plate. The output shaft of the servo motor rotates through the first fixed plate and is fixedly fitted with a gear. A first rack and a second rack are slidably connected to one side of the first fixed plate. The first rack and the second rack are centrally symmetrical and located on opposite sides of the gear, respectively. Both the first rack and the second rack mesh with the gear. A first connecting rod is fixedly connected to one side of the first rack. A heating plate is fixedly connected to one end of the first connecting rod. The heating plate is located directly above the rectangular frame, and multiple heating tubes are disposed inside the heating plate.
[0011] In one possible design, a horizontal plate is fixedly connected to the bottom of the second rack, a round rod is fixedly connected to the top of the horizontal plate, and a top plate is fixedly connected to the top of the round rod, the top plate being located between the two conveyor belts of the first conveyor belt.
[0012] In one possible design, the pressing assembly includes a sliding block slidably connected inside a first rectangular hole. One end of the sliding block is fixedly connected to a pressure plate, which is located above a second conveyor belt. The bottom of the sliding block is fixedly connected to the same spring between it and the bottom inner wall of the first rectangular hole. A second fixing plate is provided inside the laminating machine body. The second fixing plate is located inside the second conveyor belt and cooperates with the pressure plate. A second rectangular hole is opened on one side of the laminating machine body. One end of the sliding block is fixedly connected to a crossbar. One end of the crossbar slides through the second rectangular hole and is fixedly connected to a push rod. One end of the output shaft of the servo motor is fixedly connected to a push plate, which cooperates with the push rod.
[0013] In one possible design, multiple fans are provided on the top inner wall of the composite machine body.
[0014] In this application, during use, the sheet body to be pressed is placed on the second conveyor belt and the first conveyor belt respectively. Through the continuous transmission of the first conveyor belt and the second conveyor belt, the lower sheet body is still on the first conveyor belt, and the upper sheet body falls into the inside of the rectangular frame.
[0015] The servo motor is started, and the output shaft of the servo motor drives the gear to rotate forward and backward. The gear drives the two first racks to move closer and then further apart. At this time, the second rack drives the top plate to move up and down through the horizontal plate and the round rod. The first rack drives the first rack and the heating plate to move up and down. After the two sheet bodies are in place, the air between the two sheet bodies is extracted by the vacuum pump to facilitate the two sheet bodies to fit together. At this time, the heating tube inside the heating plate is activated, and the top plate lifts the sheet body below into the inside of the round hole. The heating plate then combines the two sheet bodies.
[0016] The composite sheet body moves back down to the top of the crossbar and is transported forward. After being cooled by the fan, it is shaped. At the same time, the output shaft of the servo motor drives the push plate to rotate in both directions. The push plate can push the push rod to move down, the push rod drives the crossbar to move down, the crossbar drives the sliding block to move down, and the sliding block drives the pressure plate to move down. Through the pressing of the pressure plate, the composite effect of the two sheet bodies is ensured again. When the push plate separates from the push rod, the spring force can help the pressure plate return to its original position for easy use next time.
[0017] Beneficial Effects: Improved Lamination Performance: This application achieves solvent-free lamination of sheet materials by setting up a lamination component, including multiple circular holes and air extraction holes on the inner wall of a rectangular frame, and a heating plate located directly above the rectangular frame. The heating tubes inside the heating plate can heat the sheet material, softening it and making it easier to bond. At the same time, the air extraction holes can remove air between the sheet materials, preventing the formation of air bubbles, thereby improving the lamination performance.
[0018] Enhanced composite stability: By incorporating a driving assembly, including a servo motor, gears, and a first and second rack, precise control of the heating plate and top plate can be achieved. Once the two sheet bodies are in position, the servo motor drives the gears in both forward and reverse directions, causing the first and second racks to move closer together and then further apart. This, in turn, moves the heating plate and top plate up and down, lifting the lower sheet body into the circular hole and ensuring a tight fit with the upper sheet body. This control method not only improves the stability of the composite process but also ensures precise alignment during lamination.
[0019] Optimized pressing effect: By setting up a pressing assembly, including components such as sliding blocks, pressure plates, springs, crossbars, and push rods, the laminated sheet body can be pressed again. When the laminated sheet body moves back down to the top of the crossbar, the servo motor drives the push plate to rotate forward and backward, pushing the push rod downward, thereby causing the pressure plate to move down and press the sheet body. This design not only further ensures the lamination effect but also improves the flatness and firmness of the sheet body.
[0020] Improved production efficiency: The solventless laminating machine of this application achieves rapid and efficient lamination of sheet materials by optimizing the lamination process and flow. Simultaneously, by incorporating multiple fans to cool and shape the laminated sheet material, the production cycle is further shortened, thus improving production efficiency.
