Thus, since each of the second sheets 32 has a tackiness, a plurality of the second sheets 32 can be spliced together by a sheet splicing method to form a wide sheet processed by a large-sized extruder in the related art. Thus, the technical scheme of the embodiment can reduce the cost of equipment for processing the first film 31 and the floor area of the equipment, and is beneficial to the miniaturization of the equipment. Therefore, the extruder with small specification can be selected to process the wide film, the extruder with large specification in the related technology is avoided, the price of the extruder with large specification is reduced, and the operation and maintenance are labor-saving. Therefore, the technical scheme of the embodiment effectively solves the problems that the large-specification extruder in the related art is expensive and labor-consuming to operate and maintain. In addition, the film splicing method of the embodiment has novel implementation steps and simple process, and can meet the requirements of processing films with different widths.

In this way, the first film 31 is cooled to a predetermined temperature and then fed to the stocker 82, and the first film 31 can be intermittently operated in the next step in the stocker 82. During the storing process, the first film 31 is cut by the cutting device 40. This is easy to implement and the first film 31 can be cut easily. The above-described subsequent process, such as the cutting device 40, intermittently cuts the first film 31. Or the pick-up device 61 intermittently picks up each second film 32 onto the second conveyor belt 62 so that the long side of the succeeding second film 32 is spliced with the long side of the preceding second film 32.

Thus, since each second film 32 has adhesiveness, the long side of the subsequent second film 32 can be bonded to the long side of the previous second film 32. The second sheets of film 32 are sequentially bonded to form a single wide sheet of film. Thus, the technical scheme of the embodiment can reduce the cost of equipment for processing the first film 31 and the floor area of the equipment, and is beneficial to the miniaturization of the equipment.

When the plate suction cups 6131 flatly suck the second film 32, the lifting device 612 retracts and takes up the second film 32 (as shown in fig. 4 in the direction of the arrow moving upward on the second conveyor belt 62) to detach the second film 32 from the intermediate conveyor belt 50. When the linear motion module 611 can bring the lifting device 612 close to the second conveyor belt 62 (the moving direction of the linear motion module 611 is the direction of the obliquely upward arrow shown in fig. 4 along the moving direction of the second conveyor belt 62), the lifting device 612 brings the second film 32 above the second conveyor belt 62, the lifting device 612 extends again, and under the pressure applied by the lifting device 612, the long edge of the previous second film 32 is aligned with or overlapped with the long edge of the next second film 32, and is firmly bonded into a whole.
