Technical Field

[0001] The present application relates to the technical field of composite materials, and in particular to a preparation device and a preparation method for an aluminum-plastic composite tape. Background Art

[0002] In communication optical cables, aluminum-plastic composite tape is mainly used for armoring to protect the cable core, resist external forces, shield and insulate the cable. Aluminum-plastic composite tape is a packaging material made of aluminum foil and plastic materials. Usually, aluminum foil and polyester film are stretched together in a colinear manner, and under pressure and temperature, they are interlaced at the microscopic level to form a strong bond. The two materials are adhered to each other through a composite process.

[0003] The preparation of traditional aluminum-plastic composite tape is usually carried out by hot pressing or hot melting. The polyester film and aluminum sheet are conveyed together through conveyor rollers, and the bonded polyester film and aluminum sheet are stretched by conveyor rollers and then laminated at high temperature in an oven.

[0004] Then the traditional preparation equipment of aluminum-plastic composite tape usually unwinds with an unwinding device, heats with a heating device, laminates with a heat-laminating device, and then reels with a reel. This process thermally bonds the polyester film to one side of the aluminum tape, and the other side of the aluminum tape needs to go through the heat-laminating step again, so the preparation efficiency of the aluminum-plastic composite tape needs to be improved.

[0007] By adopting the above technical scheme, when preparing the aluminum-plastic composite tape, the plastic film is unwound to both sides of the aluminum tape so that both sides of the aluminum tape are attached with plastic film, so that the baked plastic film and the aluminum tape are thermally bonded and compounded to form the aluminum-plastic composite tape through the first conveying component and the second conveying component, and then the aluminum-plastic composite tape is rolled up by the winding mechanism, so that the aluminum tape can be thermally bonded with plastic film on both sides at one time, thereby improving the preparation efficiency of the aluminum-plastic composite tape.

[0009] By adopting the above technical solution, the first motor drives the first conveyor roller to rotate, and the second motor drives the second conveyor roller to rotate, so as to convey the bonded or compounded aluminum-plastic composite tape to the baking mechanism for baking, and the rotation speed of the second conveyor roller is greater than that of the first conveyor roller, so that the thermally bonded or compounded aluminum-plastic composite tape is pulled, and the aluminum tape and the plastic film are further compacted and compounded through the extrusion of the second conveyor roller, which helps to improve the compounding quality of the aluminum-plastic composite tape.

[0010] Optionally, the conveying heat sticking mechanism also includes a heat sticking component arranged between the baking mechanism and the second conveying component, and the heat sticking component includes: a heat sticking table, which is arranged below the aluminum-plastic composite belt and heats the aluminum-plastic composite belt; a base, which is arranged on one side of the heat sticking table; an elliptical roller, which is arranged above the heat sticking table and presses the aluminum-plastic composite belt onto the heat sticking table; and a driving member, which is arranged on the base and is used to drive the elliptical roller to rotate.

[0013] By adopting the above technical scheme, when the elliptical roller is driven to rotate and compact the aluminum-plastic composite strip, the driving motor drives the swing arm to rotate, and the swing arm drives the slider to rotate. However, since the slider is restricted by the limiting plate, it can only slide in the horizontal direction in the limiting plate, but since the limiting plate can only slide in the vertical direction, the swing arm drives the slider to rotate, and the limiting plate slides up and down while the slider slides in the limiting plate, so that the movement trajectory of the slider in the vertical direction is elliptical, and then the slider drives the elliptical roller to rotate with the transmission of the aluminum-plastic composite strip, so that the elliptical roller rotates and rolls under the drive of the slider to compact and bond the aluminum-plastic composite strip on the hot bonding table.

The preparation equipment also includes an adjusting mechanism, which is used to adjust the distance between the second conveying component and the baking mechanism while also adjusting the height of the driving seat.
