When the second positioning assembly on the conveying roller 2 rotates to the first refrigeration film body 13, the second socket 34 is constrained by the second positioning assembly. When the first positioning assembly and the first refrigeration film body 13 slide to the compression and shaping device, since the first insertion plate 31 of the first positioning assembly is located inside the arc-shaped spring sheet 32, it will not trigger the compression and shaping device under the guidance of the arc-shaped spring sheet 32. When the second positioning assembly and the first refrigeration film body 13 slide to the compression and shaping device, the end of the second insertion plate 26 is clamped with the push block 41 at both ends of the protective sliding plate 40, so as to slide the protective sliding plate 40 into the engaging cavity 35. At this time, the through hole 42 on the protective sliding plate 40 is slid to the communication part of the engaging cavity 35 and the feeding channel 16, and the other end of the first refrigeration film body 13 is conveyed into the engaging cavity 35 under the conveying of the damping roller 18. At this time, the rear segment of the first refrigeration film body 13 and the front end of the second refrigeration film body 14 have not completely slid into the engaging cavity 35, so the rear segment of the first refrigeration film body 13 and the front end of the second refrigeration film body 14 are overlapped in the engaging cavity 35, and the overlapping part is located at the heating cavity 19. With the conveying of the second refrigeration film body 14 into the engaging cavity 35, the second insertion plate 26 is inserted into the third socket 38, so that the rear segment of the first refrigeration film body 13 and the front end of the second refrigeration film body 14 are fixed and then slid into the arc-shaped plate 36. The overlapping part of the first refrigeration film body 13 and the second refrigeration film body 14 is heated in the engaging cavity 35 of the arc-shaped plate 36 by the heating resistance wire 21, so that the plastic soft glue at the overlapping part is melted. At this time, the melted material can be prevented from flowing out from below under the compression of the raised part of the arc-shaped sheet 37, and the arc-shaped plate 36 is driven by the elastic pressure of the pressing spring 46 to press the overlapping part, so that the excess plastic material generated by melting is discharged from the discharge port 15, facilitating the recycling of plastic for processing and reuse in other processes. At the same time, the thickness of the overlapping part is controlled to be consistent with the first refrigeration film body 13 and the second refrigeration film body 14, so as to achieve the purpose of butt joint, and the discharged material is cut by the cutting disc 48, so that the two sides of the overlapping part are flat.
