Technical Field

[0001] This utility model belongs to the field of roll material production technology, and in particular relates to a roll material for easy-to-peel products. Background Technology

[0002] In today's product manufacturing and production field, the production and preparation of small products faces a series of pressing problems. Due to their small overall size, these products are relatively more difficult to manufacture. Crucially, if there are gaps in the middle of a small product, this structural defect directly leads to a lack of continuity and sufficient support throughout the entire product.

[0003] In the crucial production process of automated product stripping, the aforementioned structural issues hinder the precise and stable gripping and handling of such products by automated equipment. The lack of continuity makes the product prone to localized stress concentration under load, leading to damage; while insufficient support prevents the product from maintaining a stable posture during stripping, causing automated stripping to fall short of expectations and severely impacting production efficiency and product quality. Innovative solutions are urgently needed to overcome these challenges. Utility Model Content

[0004] To address the problem described in the background art where automated equipment struggles to accurately and stably grasp and process small products during the crucial automated product stripping process, the present invention proposes the following technical solution:

[0005] A roll of easily peelable product includes: release paper and multiple products; the surface of the release paper is provided with multiple arrayed cutting lines, each product is adhered to the surface of the release paper, and each product is matched with one of the cutting lines; when the doctor blade peels off the products, the drive roller drives the release paper to rewind, and each cutting line forms a partial opening on the surface of the release paper, thereby forcing the release paper to separate from the products.

[0006] In this case, the edge of the orthographic projection of each product on the release paper overlaps with the corresponding blade line portion.

[0007] Furthermore, each of the aforementioned cutting edges includes: a first part, a second part, and a third part; the two sides of the first part are tangent to the first part and the second part, respectively; the opening direction of the first part is opposite to the opening direction of the second part; and the opening direction of the second part is the same as the opening direction of the third part.

[0008] Furthermore, the second part and the third part are symmetrical about the centerline of the first part.

[0009] Further, in the array of each knife line, the midline of each first part of the same row arranged along the length direction of the release paper is collinear, and the tangent of each first part peak of the same column arranged along the width direction of the release paper is collinear.

[0010] Further, the opening direction of the release paper is opposite to the opening direction of the first part.

[0011] Further, the product comprises: a glue layer and an adhesive layer; one side of the glue layer is pasted on the surface of the release paper, and the other side of the glue layer is bonded and fixed with the adhesive layer; the adhesive layer and the glue layer overlap in the orthographic projection on the surface of the release paper.

[0012] Beneficial effects: the utility model discloses a surface of release paper forms the knife line convenient for separating the product, so that the scraper can form the local opening on the surface of release paper when scraping the product, and further, the scraper can accurately cut into the connecting place of release paper and the product.

[0018] Figure 1 It is a structure schematic view of a roll material of an easy-to-peel product according to an embodiment of the utility model.

[0019] Reference Figure 1The utility model discloses an easy peel product's roll material, according to the utility model embodiment, it includes: release paper 1 and a plurality of products 2, the surface of release paper 1 is equipped with multiple knife lines 3, every knife line 3 is arrayed along the length direction of release paper 1, and the number of knife line 3 is mutually matched with the number of product 2, every product 2 is adhered on the surface of release paper 1, and every product 2 is located above a knife line 3 to facilitate subsequent removal of every product 2.

[0020] When the product 2 needs to be peeled, the scraper 4 acts on the product 2, and at the same time, the transmission roller 5 starts to drive the release paper 1 to perform a rewinding movement. In this process, every knife line 3 forms a local opening on the surface of the release paper 1. The appearance of this local opening causes the local deformation of the release paper 1, so that the scraper 4 can more accurately cut into the connection between the product 2 and the release paper 1, so that the product 2 can be more easily separated from the release paper 1.

[0022] Referring to Figure 2 and Figure 3 , further, the edge of the orthographic projection of every product 2 on the release paper 1 partially overlaps the corresponding knife line 3. This overlap makes the local opening produced by the knife line 3 during the peeling process cause the release paper 1 at the lower end of the product 2 to protrude relative to the release paper 1 on both sides of the knife line 3, which helps the scraper 4 to remove the product 2.

[0023] Specifically, every knife line 3 includes a continuous first part 31, a second part 32 and a third part 33. The two sides of the first part 31 are tangent to the first part 31 and the second part 32 respectively, and the connection of each part forms a continuous arc of a wavy line. The opening direction of the first part 31 is opposite to the opening direction of the second part 32, the opening direction of the second part 32 is the same as the opening direction of the third part 33, and the second part 32 and the third part 33 are symmetric about the middle line of the first part 31. In the array formed by every knife line 3, the middle lines of every first part 31 in the same row arranged along the length direction of the release paper 1 are collinear, and the tangents of the wave crests of every first part 31 in the same column arranged along the width direction of the release paper 1 are collinear. In addition, the opening direction of the release paper 1 is opposite to the opening direction of the first part 31, so that the scraper 4 can be opposite to the knife line 3 during the material removal process.

[0024] In addition, in the embodiment, the product 2 has a clear layered structure. The product 2 comprises a glue layer 21 and an adhesive layer 22, one side of the glue layer 21 is closely attached to the surface of the release paper 1, and the adhesion of the glue layer 21 itself ensures that the product 2 can be firmly attached to the release paper 1; the other side of the glue layer 21 is bonded and fixed with the adhesive layer 22, and the two form a complete whole. The adhesive layer 22 and the glue layer 21 overlap each other in the orthographic projection on the surface of the release paper 1, and the adhesive layer 22 is recessed to form an annular structure. In other embodiments, the shape of the adhesive layer 22 can be designed as needed to meet the requirements of different part processing.

[0025] In summary, the utility model discloses the surface of release paper forms the knife line of product convenient to separate, makes the scraper when scraping product can form the local mouth of release paper surface, and further makes the scraper can accurately cut into the connecting place of release paper and product.
