Description

Technical Field

[0001] The present invention relates to the technical field of guide roller structures, and specifically to an anti-sticking structure of a material guiding jig. Background Art

[0002] In the die-cutting field, after the release film of the corresponding layer of the coiled material with an adhesive layer is removed, the adhesive layer needs to be centered and tensioned through a guide roller and then laminated with the surface of the corresponding product or the corresponding film layer. Since the release film of the adhesive layer of the coiled material has been removed, in order not to damage the adhesive layer of the coiled material, a flexible rubber roller needs to be provided at the corresponding guide roller position. However, the surface of the rubber roller will adhere to the adhesive layer. Therefore, in the existing structure, it can only be directly laminated with the surface of the subsequent product or the corresponding film layer after removing the release film of the adhesive layer, and it is impossible to ensure the centering and tension degree of the adhesive layer and the subsequent gluing surface position. For this reason, an anti-sticking material guiding jig is urgently needed. Summary of the Invention

[0003] In view of the above problems, the present invention provides an anti-sticking structure of a material guiding jig, which laminates with the surface of the subsequent product or the corresponding film layer after centering and tensioning after removing the release film of the adhesive layer, ensuring accurate and reliable adhesion of the adhesive layer.

[0012] It is further characterized in that:

[0013] The first roller shaft is arranged directly above the second roller shaft, the two rotating shafts are respectively arranged on both sides of the upper part of the first roller shaft, and the center line of the rotating shaft is arranged parallel to the first roller shaft;

[0021] The height of the pressing area is used to pass a coil material with an adhesive layer, and the adhesive layer is arranged on the exposed surface facing the release film.

[0022] After adopting the above technical solution, the height of the pressing area is used to pass a coil material with an adhesive layer, and the adhesive layer is arranged on the exposed surface facing the release film. The release film is closed and tensioned around the two rotating shafts and the pressing area. The release film is coated on the arc-shaped pressing surface of the first roller shaft facing the pressing area. The surface of the release film facing the second roller shaft is used to drive the corresponding adhesive layer, which enables the release film to form a rotatable continuous release film channel through the first roller shaft and the two rotating shafts. The adhesive layer is arranged facing the release film and is centered and pressed and then centered and tensioned by the drive of the first roller shaft. After that, it can be directly adhered to the surface of the product and the corresponding film layer behind.

[0031] The surface of the release film 40 facing the second roller shaft 20 is used to drive the corresponding adhesive layer.

[0032] Specific embodiment one, see Figure 1 : The first roller shaft 10 is arranged directly above the second roller shaft 20. The two rotating shafts 30 are respectively arranged on both upper sides of the first roller shaft 10, and the center line of the rotating shaft 30 is arranged parallel to the first roller shaft 10.

The two rotating shafts 30 are respectively arranged on both lower sides of the first roller shaft 10, and the rotating shaft 30 is arranged parallel to the center line of the first roller shaft 10.

[0034] In specific embodiment one and specific embodiment two, a rotating roller 60 is sleeved on each rotating shaft 30. The rotating roller 60 is arranged on the rotating shaft 30 through a bearing (not shown in the figure), and the rotating roller 60 is arranged along the axial position of the rotating shaft 30 and the axial position is adjusted according to actual needs;

[0035] The axial length of the rotating roller 60 covers the width of the release film 40 to ensure that the entire release film 40 is covered on the outer circumference of the rotating roller;

[0036] Both ends of each rotating shaft 30 are respectively inserted into the upper part of the vertical support 70. The bottom of the vertical support 70 is fixedly provided with a base insertion plate 80 through a bolt 71, and the insertion end 81 of the base insertion plate 80 is used to fixedly connect the corresponding connection device;

[0037] Side baffles 61 are respectively arranged at both axial ends of the rotating roller 60, so that the release film 40 is not easily separated.

[0038] In specific implementation, the first roller shaft 10 is specifically a rubber roller shaft; the second roller shaft 20 is specifically a steel roller shaft; the height of the pressing area 40 is used for passing a coiled material with an adhesive layer, and the adhesive layer is arranged facing the exposed surface of the release film 40. The outer ring surface of the rotating shaft 30 is coated with Teflon to ensure that there is no obstacle to the axial movement of the rotating roller 60.

The height of the pressing area is used for passing a coiled material with an adhesive layer, and the adhesive layer is arranged facing the exposed surface of the release film. The release film is enclosed and tension-wound around the two rotating shafts and the pressing area. The release film covers the arc-shaped pressing surface of the first roller shaft facing the pressing area; the surface of the release film facing the second roller shaft is used to drive the corresponding adhesive layer, which enables the release film to form a continuous rotatable release film channel through the first roller shaft and the two rotating shafts. The adhesive layer is arranged facing the release film and is centered and pressed by the drive of the first roller shaft and then centered and tensioned. After that, it can be directly adhered to the surface of the product and the corresponding film layer at the rear. After the adhesive layer removes the release film, it is compounded with the surface of the product or the corresponding film layer at the rear through centering and tensioning to ensure the accurate and reliable adhesion of the adhesive layer.
