Description

Technical Field

[0001] This invention relates to the field of self-adhesive coating and laminating technology, and more particularly to a self-adhesive coating and laminating machine. Background Technology

[0002] The self-adhesive is applied to the release paper by a self-adhesive coating machine. The self-adhesive on the release paper is transferred to the label material by a laminating machine, so that the label material and the release paper form a combination. In the laminating machine, the self-adhesive on the release paper is transferred to the label material by a laminating roller (a chrome-plated light roller cooled). The label material and the release paper are pressed together by a pressing roller to form a combination.

[0003] The self-adhesive (adhesive layer) obtained through the above production process has a smooth surface. When the label material is adhered to objects such as packaging bottles through this smooth self-adhesive (adhesive layer), the air between the self-adhesive (adhesive layer) and the packaging bottle or other objects is difficult to expel, which leads to the formation of air bubbles on the surface of the label material and affects the appearance of the product. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that air is difficult to expel between the self-adhesive (adhesive layer) and objects such as packaging bottles in the existing technology, and to propose a self-adhesive coating and laminating machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design a self-adhesive coating and laminating machine, including a laminating roller and a pressing roller, and further comprising:

[0007] An adhesive layer embossing assembly is disposed between the composite roller and the pressing roller. The adhesive layer embossing assembly includes an anti-sticking embossing roller and a first rubber roller. The anti-sticking embossing roller can guide the label material with the adhesive layer to move forward, and the first rubber roller can guide the release paper to move forward. The surface of the anti-sticking embossing roller has embossing, and the anti-sticking embossing roller can squeeze the adhesive layer and make the surface of the adhesive layer form a texture.

[0008] Preferably, a second rubber roller is disposed below the anti-sticking embossing roller, and the second rubber roller is close to the anti-sticking embossing roller.

[0009] Preferably, the distance between the anti-sticking embossing roller and the first rubber roller and the composite roller and the pressing roller is equal.

[0010] Preferably, the texture on the surface of the anti-stick embossing roller is longitudinally arranged, the longitudinally arranged texture connects the left and right ends of the anti-stick embossing roller, and multiple sets of longitudinally arranged textures are arranged around the outer circumference of the anti-stick embossing roller.

[0011] Preferably, the surface of the anti-sticking embossing roller is further provided with multiple sets of annular patterns, which connect the multiple sets of longitudinally formed patterns.

[0012] The self-adhesive coating and laminating machine proposed in this invention has the following advantages:

[0013] The anti-stick embossing roller and the first rubber roller can separate the release paper and label material after the adhesive layer has been exchanged. The anti-stick embossing roller embosses the surface of the adhesive layer, so that the surface of the adhesive layer has continuous and connected textures. When the label material is bonded to the packaging bottle or other objects through the textured adhesive layer, the excess air can be discharged outward through the texture on the adhesive layer, so as to avoid the formation of air bubbles on the surface of the label material and improve the appearance of the product.

[0014] By performing a secondary separation between the release paper and the label material after the adhesive layer has been exchanged, the adhesive layer has a longer cooling gap, which improves the plasticity of the adhesive layer after embossing and the adhesion strength between the adhesive layer and the label material.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Example 1

[0021] Reference Figure 1 , Figure 2 A self-adhesive coating and laminating machine includes a laminating roller 4 and a pressing roller 5, and further includes:

[0022] The adhesive layer embossing assembly is disposed between the composite roller 4 and the pressing roller 5. The adhesive layer embossing assembly includes an anti-sticking embossing roller 6 and a first rubber roller 7. The anti-sticking embossing roller 6 can guide the label material 10 with the adhesive layer to move forward, and the first rubber roller 7 can guide the release paper 9 to move forward. The surface of the anti-sticking embossing roller 6 has embossing, and the anti-sticking embossing roller 6 can squeeze the adhesive layer and make the surface of the adhesive layer form a texture.

[0023] Working principle:

[0024] Reference Figure 3 The figure shows a schematic diagram of a self-adhesive coating and laminating machine in the prior art, and its working process is as follows:

[0025] The release paper 9 is coated with an adhesive layer by heating the oven 1, and the adhesive layer is heated. The heated release paper 9 coated with the adhesive layer is fed between the composite roller 4 and the pressing roller 5.

[0026] At the same time, the label material 10 is conveyed between the composite roller 4 and the pressing roller 5 through the feeding roller 2;

[0027] The side of the release paper 9 with the adhesive layer is in contact with the label material 10. Under the action of the composite roller 4, the adhesive layer coated on the release paper 9 is adhered to the label material 10. At the same time, under the action of the pressing roller 5, the release paper 9 and the label material 10 are in close contact.

[0028] The release paper 9 and the label material 10 are combined and collected by the receiving roller 3.

[0029] Therefore, in the prior art, after heating in the heating oven 1 and pressing by the pressing roller 5, the adhesive layer surface of the label material 10 is flat. When the label material 10 with a flat adhesive layer is affixed to objects such as packaging bottles, the air between the adhesive layer and the packaging bottles is difficult to escape, which leads to the formation of air bubbles between the label material 10 and the packaging bottles, affecting the appearance of the product.

[0030] To solve the above problems, in this embodiment, after the adhesive layer is transferred between the release paper 9 and the label material 10, the release paper 9 and the label material 10 with the adhesive layer are separated again. After separation, the surface of the adhesive layer is embossed by the anti-sticking embossing roller 6, so that the surface of the adhesive layer has a texture. Then, the release paper 9 and the label material 10 with the adhesive layer are pressed together again. The workflow is as follows:

[0031] Heated release paper 9 coated with adhesive is fed to composite roller 4 through heating oven 1, and label material 10 is fed to composite roller 4 through feeding roller 2;

[0032] Under the action of the composite roller 4, the adhesive layer coated on the release paper 9 is transferred to the label material 10;

[0033] The label material 10 with the adhesive layer is fed to the anti-sticking embossing roller 6. The surface of the adhesive layer is embossed by the anti-sticking embossing roller 6. The release paper 9 is fed to the first rubber roller 7, so that the release paper 9 is temporarily separated from the label material 10 with the adhesive layer. During the separation process between the label material 10 and the release paper 9, the adhesive layer transferred to the label material 10 can be further cooled and shaped, so that the adhesive layer and the label material 10 have a higher adhesion strength.

[0034] The embossed label material 10 with adhesive layer and the release paper 9 are fed into the pressing roller 5. The pressing roller 5 is provided with two sets. The two sets of pressing rollers 5 squeeze the release paper 9 and the label material 10 from top to bottom, so that the release paper 9 and the label material 10 can be combined. Finally, the combination of the release paper 9 and the label material 10 is fed into the take-up roller 3 for winding.

[0035] By embossing the surface of the adhesive layer, air between the adhesive layer and the packaging bottle or other objects can be expelled through the texture of the adhesive layer surface, preventing air bubbles from forming between the label material 10 and the packaging bottle or other objects, thus improving the product's appearance.

[0036] Example 2

[0037] To further improve the embossing effect on the adhesive layer, refer to Figure 1 , Figure 2 A second rubber roller 8 is provided below the anti-sticking embossing roller 6, and the second rubber roller 8 is close to the anti-sticking embossing roller 6; the distance between the anti-sticking embossing roller 6 and the first rubber roller 7 and the composite roller 4 and the pressing roller 5 is equal.

[0038] Working principle:

[0039] The label material 10 with an adhesive layer is clamped between the second rubber roller 8 and the anti-sticking embossing roller 6 by the second rubber roller 8, so that the adhesive layer and the anti-sticking embossing roller 6 have higher extrusion strength and improve the embossing effect; and the surface of the second rubber roller 8 is smooth and the texture of the second rubber roller 8 is soft, so as to avoid the label material 10 being excessively squeezed by the anti-sticking embossing roller 6, which would cause the surface of the label material 10 to also form texture.

[0040] Reference Figure 2 To prevent misalignment between the label material 10 and the release liner during the secondary separation process, the composite roller 4, pressing roller 5, anti-sticking embossing roller 6, and first rubber roller 7 together form an equilateral quadrilateral structure. In actual use, it is only necessary to ensure that the stroke between the anti-sticking embossing roller 6 and the composite roller 4 and pressing roller 5 is equal to the stroke between the first rubber roller 7 and the composite roller 4 and pressing roller 5.

[0041] Example 3

[0042] To improve the air expulsion effect of the adhesive layer, refer to Figure 2 The texture on the surface of the anti-stick embossing roller 6 is longitudinally opened, and the longitudinally opened texture connects the left and right ends of the anti-stick embossing roller 6. Multiple sets of longitudinally opened textures are opened around the outer circumference of the anti-stick embossing roller 6. Multiple sets of annular textures are also opened around the circumference of the surface of the anti-stick embossing roller 6, and the annular textures connect the multiple sets of longitudinally opened textures.

[0043] Working principle:

[0044] The multiple sets of vertical grooves allow air between the adhesive layer and the packaging bottle to escape along the grooves. The multiple sets of annular grooves allow the vertical grooves to connect with each other, thereby improving the air expulsion effect.

[0045] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
