Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "bottom" and "top," "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.
The utility model provides a PVC shrink film, as shown in figure 1, includes shrink film base member 1, and 1 terminal surface of shrink film base member can dismantle and be connected with a plurality of mark layers 2, and the interval of adjacent mark layer 2 equals, and the material of mark layer 2 is PVC, and the terminal surface printing that shrink film base member 1 was kept away from to mark layer 2 has the mark. By separating the marking layer 2 from the shrink film substrate 1, the shape of the marking layer 2 is not affected when the shrink film substrate 1 shrinks, and the printed mark is not deformed.
As shown in fig. 2, since the entire shape of the shrink film substrate 1 is deformed after shrinking, the mark layer 2 is wrinkled at this time, which affects the recognition of the mark. Therefore, four through holes 11 penetrate through the end face of the shrink film substrate 1, and the four through holes 11 are respectively close to the two side faces of the mark layer 2. The side wall of the mark layer 2 is integrally formed with two connecting blocks 21 matched with the through holes 11, and the connecting blocks 21 can penetrate through the through holes 11 to be abutted to the end face, far away from the mark layer 2, of the shrink film matrix 1. Therefore, when the shrink film body shrinks and deforms, the connecting block 21 can be placed in the through hole 11 to generate fine sliding, so that the mark layer 2 cannot generate wrinkles along with the shrinkage of the shrink film substrate 1, and the printed marks can be kept clear.
In order to make the connection between the marking layer 2 and the shrink film base 1 more firm, the marking layer 2 is not disconnected from the shrink film base 1 during use. As shown in fig. 2, a first adsorption layer 24 is adhered to an end face of the connection block 21 close to the shrink film substrate 1, and the first adsorption layer 24 may abut on an end face of the shrink film substrate 1 away from the marker layer 2. The end face of the mark layer 2 close to the shrink film base body 1 is adhered with a second adsorption layer 25, and the second adsorption layer 25 can be abutted against the end face of the shrink film base body 1 close to the mark layer 2. The first adsorption layer 24 and the second adsorption layer 25 are both electrostatic adsorption films. The first adsorption layer 24 and the second adsorption layer 25 are used for increasing the connection strength between the marking layer 2 and the shrink film substrate 1, so that the marking layer 2 and the shrink film substrate 1 are not easy to separate.
In order to further increase the bonding strength between the marking layer 2 and the shrink film base 1, the marking layer 2 and the shrink film base 1 are not easily separated. As shown in fig. 2, the two side surfaces of the connecting block 21 are integrally formed with the abutting blocks 22, the end surface of the abutting block 22 close to the mark layer 2 can abut against the end surface of the shrink film base 1 far from the mark layer 2, and the distance between the end surfaces of the two abutting blocks 22 far from each other is greater than the length of the through hole 11. When the direction that keeps away from shrink film base member 1 at mark layer 2 removed, butt piece 22 can keep away from the terminal surface butt of mark layer 2 with shrink film base member 1, utilizes butt piece 22 to obstruct connecting block 21 and passes from through-hole 11 in to make connecting block 21 be difficult for producing with shrink film base member 1 and break away from, thereby make the connection between mark layer 2 and the shrink film base member 1 more firm.
As shown in fig. 2, when the connecting block 21 is inserted into the through hole 11, the abutment block 22 needs to be inserted into the through hole 11, and at this time, the abutment block 22 needs to be manually bent toward the connecting block 21 to allow the abutment block 22 to be inserted into the through hole 11. Therefore, the end face, away from the mark layer 2, of the abutting block 22 is provided with the wedge-shaped surface 23, and the end face, away from the connecting block 21, of the wedge-shaped surface 23 inclines towards the direction close to the mark layer 2. When the butt block 22 passes through the through hole 11, the wedge-shaped surface 23 is used for applying a force towards the direction of the connecting block 21 to the butt block 22, so that the butt block 22 inclines towards the direction of the connecting block 21, the butt block 22 does not influence the process that the connecting block 21 passes through the through hole 11, and the connection between the mark layer 2 and the shrink film substrate 1 is more convenient.
As shown in fig. 2, since the thickness of the connection block 21 is small, the side wall of the through hole 11 is cut in the process of inserting the connection block 21 into the through hole 11, the length of the through hole 11 is increased, and the abutment block 22 cannot restrict the movement of the connection block 21. Therefore, a layer of fixing ring 12 is adhered in the through hole 11, and the fixing ring 12 is made of PVC. Utilize solid fixed ring 12 to make connecting block 21 can not direct and through-hole 11 lateral wall contact to make connecting block 21 can not produce the cutting to through-hole 11 lateral wall, make the length of through-hole 11 can not change, connecting block 21 can not follow and drop in through-hole 11, and then make the connection between marker layer 2 and the shrink membrane substrate more firm.
The working principle is as follows:
one ends of the four connecting blocks 21 far away from the mark layer 2 are respectively inserted into the through holes 11, then the connecting blocks 21 move towards the through holes 11 simultaneously, the abutting blocks 22 penetrate through the through holes 11, then the mark layer 2 abuts against the end face of the shrink film matrix 1, the mark layer 2 is attached to the shrink film matrix 1 by utilizing the second adsorption layer 25, then the connecting blocks 21 move towards the end face of the shrink film matrix 1 far away from the mark layer 2, the first adsorption layer 24 is attached to the shrink film matrix 1, at the moment, the connection between the mark layer 2 and the shrink film matrix 1 is completed, when the shrink film matrix 1 shrinks, the connecting blocks 21 cannot slightly slide with the through holes 11, the shrinkage of the shrink film matrix 1 cannot influence the shape of the mark layer 2, and marks on the mark layer 2 can still keep clear.
The specific embodiments are 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 embodiments without inventive contribution as required after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
