Abstract
Description
Technical Field
[0001] The present application relates to the technical field of sole stickers, and in particular to a sole sticker and a production method thereof. Background Art
[0002] As an important part of the shoe in contact with the ground, the sole undertakes functions such as supporting the human body, buffering impact, and providing grip. Common materials include rubber, polyurethane, etc. The sole anti-wear sticker is a protective material attached to the surface of the sole, aiming to increase the wear resistance of the sole, extend the service life of the sole, and reduce the use cost. However, the existing sole anti-wear stickers have the following obvious drawbacks. First, the designs of many anti-wear stickers are relatively single, and the fixed shape and size are difficult to fit complex sole contours. After pasting, edge warping and other situations are likely to occur, and they will also wear and fade during use.
[0003] Secondly, the existing anti-wear stickers rely on glue for fixation, which is greatly affected by environmental factors. The viscosity decreases at high temperature and humidity, and the glue becomes brittle at low temperature, resulting in easy detachment of the anti-wear stickers and affecting their protection effect. When replacing, the glue residue is difficult to clean, will adsorb impurities and damage the sole. Frequent replacement will also damage the structures such as the waterproof layer and anti-slip layer of the sole. Summary of the Invention
[0004] The present application aims to solve at least one of the technical problems in the related art to some extent.
[0005] To achieve the above object, a sole sticker is proposed in the first aspect embodiment of the present application, including a sole sticker substrate and a plurality of convex portions, wherein the plurality of convex portions are on the upper surface of the sole sticker substrate; the plurality of convex portions are in one-to-one correspondence with a plurality of sole pattern concave portions of the sole to be pasted.

[0007] In an embodiment of the present application, a texture structure is provided at the bottom of the sole sticker.
[0008] In an embodiment of the present application, the size of the sole sticker does not exceed the size of the sole to be pasted.
[0009] In an embodiment of the present application, the material of the sole sticker is EVA material or a mixed material of EVA and PP.
[0010] In an embodiment of the present application, the thickness of the sole sticker substrate is 3 mm.
[0011] In an embodiment of the present application, the shape of the texture structure includes herringbone pattern, wavy pattern, and grid pattern.

[0013] In addition, the above-mentioned sole sticker and the production method of the sole sticker according to the present application may further have the following additional technical features:
[0014] In an embodiment of the present application, the dimension data includes the height of the convex part of the sole pattern, the depth of the concave part of the sole pattern, and the texture spacing.

[0026] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present application, and should not be construed as limiting the present application.
[0027] A sole sticker and a production method of the sole sticker according to an embodiment of the present application will be described below with reference to the drawings.
[0028] Embodiment 1
[0029] As Figure 1 shown, an embodiment of the present invention provides a sole sticker, which may include a sole sticker substrate 1 and a plurality of protruding parts 2. Among them, the plurality of protruding parts 2 are located on the upper surface of the sole sticker substrate 1. It should be noted that the shapes and quantities of the protruding parts 2 match the sole 3 to be pasted.
[0030] Furthermore, the plurality of protruding parts 2 are in one-to-one correspondence with a plurality of sole pattern concave parts 32 of the sole 3 to be pasted. It should be noted that the height of the protruding part 2 does not exceed the depth of the sole pattern concave part 32.
[0031] In an embodiment of the present application, as Figure 2 shown, a pattern structure 12 is provided at the bottom of the sole sticker, and the shape of the pattern structure 12 includes herringbone pattern, wavy pattern, grid pattern, etc.
[0032] It should be noted that the specific shape of the pattern structure 12 can be adaptively matched according to the user's shoe-wearing environment to increase the wear resistance of the sole sticker.
[0033] In an embodiment of the present application, as Figure 3 shown, the size of the sole sticker does not exceed the size of the sole 3 to be pasted.
[0034] In an embodiment of the present application, the material of the sole sticker is EVA material or a mixed material of EVA and PP, etc. It should be noted that relevant staff can add other adaptable materials during the production process.
[0035] It is understandable that EVA material is light and flexible, has good cushioning and shock absorption, good resilience and is resistant to chemical corrosion; when EVA is mixed with PP, it has both the rigidity of PP and the elasticity of EVA, and is wear-resistant and deformation-resistant, and has improved hardness and heat resistance.
[0036] In one embodiment of the present application, the thickness of the sole sticker base 1 is 3 mm. It should be noted that the thickness of the raised portion 2 is not included in the inward retraction of the sole pattern recess 32 .
[0037] Specifically, when the user needs to use the sole sticker, such as Figure 3 As shown, the user first cleans the bottom of the sole 3 to be pasted, then matches the multiple raised parts 2 on the sole sticker with the sole pattern recesses 32 one by one, and then presses the sole sticker base 1 until the sole sticker base 1 and the sole pattern raised parts 31 contact each other.
[0038] Example 2
[0039] like Figure 4 As shown, the embodiment of the present application also provides a method for producing a shoe sole sticker, which is applied to the production of the shoe sole sticker in Example 1, comprising the following steps:
[0040] Step 1: Scan the pattern of the sole to be pasted with a 3D scanner and mark the dimensions using CAD to obtain dimension data;
[0041] Step 2: Modeling and manufacturing the mold according to the determined size data;
[0042] Step 3: Stir and heat the raw material of the shoe sole sticker until it is molten, and inject the molten raw material into the mold;
[0043] Step 4: Let it sit for 10-30 minutes until the shape cools down, then remove the sole sticker from the mold.
[0044] It should be noted that the dimensional data includes the height of the convex portion 31 of the sole pattern, the depth of the concave portion 32 of the sole pattern, and the spacing between the treads.
[0045] It should be noted that in the above-mentioned embodiment, during the mold manufacturing process, in order to achieve greater precision, the sole portion may be re-molded using low-temperature EVA raw material, scanned again using a 3D scanner (second scan data), and then compared with the dimensional data obtained by the 3D scanner (first scan data). This is because the tread protrusions 31 and tread concave portions 32 on the bottom of the sole to be attached may have barbs or deep grooves. During the 3D scanner scanning (first scan data), scan details may be lost. The prepared EVA re-molded portion is then scanned again using a 3D scanner (second scan data) to check for deviations between the two scans to facilitate subsequent adjustments.
[0046] As a possible scenario, after the sole is scanned by a 3D scanner and the corresponding sole sticker mold is made, if mass production is required subsequently, the processes of step three and step four can be transferred to an injection molding machine for implementation.
[0047] Fix the produced mold on the injection molding machine, add the mixed raw materials to the hopper of the injection molding machine, and convey them to the barrel through the rotation of the screw. In the subsequent process, the screw advances forward to inject the molten EVA raw materials into the closed mold cavity. Cold water or air is introduced into the mold to cool the temperature of the EVA sole sticker below 60°C, and the microporous structure is fixed. The cooling time is usually 10 - 20 minutes (if the time is too short, the sole is likely to deform; if it is too long, the production efficiency will be affected). Finally, the mold is opened, and the formed sole sticker is pushed out through the ejection device.
[0048] In summary, a sole sticker according to an embodiment of the present application can be adaptively matched with the sole. While maintaining the overall visual effect, it can better adapt to complex contours, avoid edge warping, wear, and fading; uses a snap - fit fixing technology to replace glue, effectively resist the influence of high - temperature and humid and low - temperature environments, enhance stability, improve wear resistance and the protection effect on the sole; there is no glue residue when replacing, does not adsorb impurities, does not damage the sole, extends the service life of the sole, reduces the trouble of frequent replacement and cleaning, reduces the use cost, and significantly improves the durability and comfort of the shoes.
