[0020] The structural features of the present utility model are now described in detail with reference to the accompanying drawings of the specification.

[0021] Example 1

[0022] See also Figure 1 and Figure 3A device for producing easy-tear release paper comprises a winding roller 1, two symmetrically arranged pressing rollers 2, and two groups of dotted line perforated roller groups, wherein the two groups of dotted line perforated roller groups are respectively arranged on both sides below the pressing roller 2, and the two groups of dotted line perforated roller groups complete the dotted line perforation of the first coated perforated layer 72 and the second coated perforated layer 73 of the easy-tear release paper, wherein the dotted line perforated roller groups comprise a correspondingly arranged upper dotted line perforated roller 3 and a lower dotted line perforated roller 4, a plurality of rows of dotted line perforated cutter heads 31 are arranged on the circumference of the upper dotted line perforated roller 3, and a dotted line perforated cutter groove 41 is arranged on the lower dotted line perforated roller 4 at a position corresponding to the dotted line perforated cutter heads 31, and the dotted line perforated roller groups on both sides perform dotted line perforation on the first coated perforated layer 72 and the second coated perforated layer 73. The membrane perforation layer 73 is subjected to rolling dotted line punching. In order to enable the upper dotted line perforation roller 3 and the lower dotted line perforation roller 4 to rollingly clamp the first membrane perforation layer 72 and the second membrane perforation layer 73, anti-skid layers 8 made of rubber are fixed on both sides of the upper dotted line perforation roller 3 located on the dotted line punching knife head 31 and the lower dotted line perforation roller 4 located on both sides of the dotted line punching knife groove 41. When the upper dotted line perforation roller 3 and the lower dotted line perforation roller 4 are performing punching and conveying on the first membrane perforation layer 72 and the second membrane perforation layer 73, the first membrane perforation layer 72 and the second membrane perforation layer 73 can be effectively prevented from sliding, thereby improving the stability of the punching and conveying of the first membrane perforation layer 72 and the second membrane perforation layer 73. Two symmetrically arranged glue coating rollers 5 are provided below the lamination roller 2, and the glue coating rollers 5 coat glue on both sides of the paper base layer 71. The glued paper base layer 71, the first coated perforated layer 72 and the second coated perforated layer 73 are superimposed and compounded through the lamination roller 2 to form a release paper 7. Two symmetrical silicone oil coating rollers 6 are provided above the lamination roller 2. The compounded release paper 7 is coated on both sides by the silicone oil coating rollers 6 and then rolled up on the winding roller 1. In order to facilitate the transmission and compounding of the paper base layer 71 and the first coated perforated layer 72 and the second coated perforated layer 73, the intersection of each group of silicone oil coating rollers 6, the lamination roller 2 and the glue coating roller 5 is located in the same plane, and the two groups of dotted line perforated roller groups are in a corresponding relationship with the dotted line perforated holes of the first coated perforated layer 72 and the second coated perforated layer 73.

[0023] Reference Figure 4The easy-to-tear release paper production device of the utility model can continuously produce improved easy-to-tear release paper. First, the paper base layer 71 is coated with glue on both sides by the glue coating roller 5, and then the first coated perforated layer 72 and the second coated perforated layer 73 can be continuously punched by two groups of dotted line perforated rollers, and dotted line perforations are formed on the first coated perforated layer 72 and the second coated perforated layer 73. Then, the paper base layer 71 and the first coated perforated layer 72 and the second coated perforated layer 73 are superimposed and composited by the pressing roller 2 to form a release paper 7. The composite release paper 7 is coated on both sides by the silicone oil coating roller 6 and then rolled up on the winding roller 1. Through the combined use of the two groups of dotted line perforated rollers, the glue coating roller 5, the pressing roller 2, the silicone oil coating roller 6 and the winding roller 1, the production of easy-to-tear release paper can be quickly completed, and continuous production can be realized with high production efficiency.

[0024] Example 2

[0025] Reference Figure 2 and Figure 3 As another preferred embodiment of the utility model, the difference from embodiment 1 is that the two groups of dotted line perforation rollers are in a staggered relationship for the dotted line perforation positions of the first film perforation layer 72 and the second film perforation layer 73. The dotted line perforation positions of the first film perforation layer 72 and the second film perforation layer 73 are staggered on both sides of the paper base layer 71, so that the dotted line perforation positions of the first film perforation layer 72 and the second film perforation layer 73 are arranged equidistantly along the length direction. The staggered arrangement can further enhance the tensile strength of the release paper 7. The release paper can be easily torn off along any adjacent cutting dotted lines on both sides, and after tearing between two adjacent cutting dotted lines, a fracture will appear, and the appearance of the fracture can make the release paper easier to peel off from the double-sided adhesive layer.

[0026] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
