As shown in fig. 3 to 5, the present embodiment provides a punched tape wrapping structure, which includes a conveyor belt 10 and a wrapping sheet 21/22.
The rounder 21/22 is a planar development of the rounder 21 '/22', or the rounder 21/22 is punched to form the rounder 21 '/22'. Specifically, the rounded sheet 21 in fig. 3 is punched and rounded to form a rounded product 21 'shown in fig. 1, and the rounded sheet 22 in fig. 4 is punched and rounded to form a rounded product 22' shown in fig. 2. Of course, the illustrated roundish sheet 21/22 and roundish products 21 '/22' are examples only and are not to be construed as limiting the specific structure of the roundish sheet or roundish product. The stamping and wrapping belt material structure provided by the embodiment can be suitable for other products needing stamping and wrapping. The specific shape of the round-wrapped sheet or round-wrapped product is not the innovation point of the scheme, and therefore, the discussion is not made.
The conveying material belt 10 comprises a material belt body 11 and at least one connecting assembly, wherein the material belt body 11 extends along the left-right direction and is provided with at least one containing hole 111 which is communicated with the upper direction and the lower direction, each connecting assembly is arranged in one containing hole 111 respectively, and each connecting assembly comprises a front connecting strip 12 and a rear connecting strip 13.
At least one round wrapping sheet 21/22 is provided, and each round wrapping sheet 21/22 is respectively disposed in one of the accommodating holes 111 and is respectively connected to the tape body 11 through a connecting assembly.
