The rotational speed of w1 is greater than the rotational speed of w2, and PET membrane transfer speed a is greater than waste material rolling speed b, and after the mould cutting produced a strip wide compound material of gluing at every turn, the PET membrane can be fast with its transportation away in order to increase the interval between the adjacent strip wide compound material of gluing, the subsequent concatenation work of being convenient for.
As shown in fig. 12, the inner side surface of the blade 811 is a flat surface, and the cut end surface of the product is more flat. Referring to fig. 10, the side of the blade 811 away from the bottom roller 8 is provided with a bevel 812, and the bevel 812 is located on the outer side of the cutting die 81, so that the sharpness of the blade 811 can be increased, and punching is facilitated.
Example 3: as shown in fig. 9, the first servo motor 9 drives the upper compression roller 7 to rotate at a constant speed, the second servo motor 10 drives the lower compression roller 8 to rotate intermittently, and with reference to fig. 10, the cutting die 81 can perform intermittent cutting on the wide glue composite material, the strip-shaped wide glue composite material formed by each cutting can be transported away by the PET film, and the distance between the adjacent strip-shaped wide glue composite materials is increased.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
