Description

Technical Field

[0001] The present invention relates to the technical field of shoe body welts, and in particular to a manufacturing process of a shoe body printed welt. Background Art

[0002] Welts can be used in both seam-stitched and glued constructions. In seam-stitched shoes, the welt is located at the edge of the sole, sewn to the upper, insole, and outsole. It serves as a connector between the upper and outsole, strengthening the bond between the upper and sole while also concealing wrinkles in the upper. In glued shoes, a false welt conceals wrinkles and provides a decorative touch. The welt serves as both a connecting element between the upper and outsole (or insole) and a decorative element. Because the welt is a prominent exposed part, it demands both internal quality and aesthetic appeal.

[0003] At present, in the traditional processing of welts, due to the lax control of the welt process, the structure of the welt molding is poor, resulting in poor quality of shoe molding and affecting the service life.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Summary of the Invention

[0005] In response to the problems in the related art, the present invention proposes a manufacturing process for a printed shoe welt to overcome the above-mentioned technical problems existing in the existing related art.

[0006] The technical solution of the present invention is achieved as follows:

[0007] A process for producing a printed welt on a shoe body comprises the following steps:

[0008] Step S1, obtaining raw materials in advance, including: welt and rubber;

[0009] Step S2, printing the front side of the welt to obtain a printed welt;

[0010] Step S3, applying glue to the back of the printed edge strip to obtain an adhesive printed edge strip;

[0011] Step S4, evenly brushing the surface of the rubber with a treatment agent to obtain a pre-bonded rubber;

[0012] Step S5, evenly brushing glue on the front of the pre-bonded rubber to obtain a tackified rubber;

[0013] Step S6, laminating the back side of the adhesive printed welt to the front side of the tackifying rubber;

[0014] Step S7: trimming the tackifying rubber along the edge of the adhesive printed welt so that the edge of the adhesive printed welt is flush with the edge of the tackifying rubber in a 1:1 ratio, thereby obtaining a finished shoe body welt.

[0015] Wherein, the welt is made of transparent material.

[0016] Wherein, the thickness of the rubber is 0.6-0.8 mm.

[0017] Wherein, the treatment agent includes the following raw material components:

[0018] Methyl ethyl ketone 40%, acetone 20%, cyclohexane 20% and ethyl acetate 20%.

[0019] The step of applying glue to the back of the printed edge strip and evenly brushing glue on the front of the pre-glued rubber sheet further includes the following steps:

[0020] Place them in an oven for drying.

[0021] Wherein, the step of uniformly brushing the surface of the rubber with the treatment agent further comprises the following steps:

[0022] Brush the treatment agent on the rubber surface and let it dry naturally.

[0023] The step of laminating the back side of the adhesive printed edge strip to the front side of the tackifying rubber comprises the following steps:

[0024] The adhesive printed edge strip and the tackifying rubber are squeezed by roller pressing.

[0025] Beneficial effects of the present invention:

[0026] The manufacturing process of the printed shoe welt of the present invention comprises the following steps: obtaining the raw material welt and rubber in advance, printing on the front of the welt to obtain the printed welt, applying glue to the back of the printed welt to obtain the adhesive printed welt, evenly brushing a treatment agent on the surface of the rubber to obtain the pre-bonded rubber, evenly brushing glue on the front of the pre-bonded rubber to obtain the tackified rubber, laminating the back of the adhesive printed welt to the front of the tackified rubber, trimming the tackified rubber along the edge of the adhesive printed welt so that the edges of the adhesive printed welt and the tackified rubber are aligned in a 1:1 ratio, and obtaining the finished shoe welt. Not only is the welt surface clean and uniform in color, but the shoe welt also has high ductility and good wear resistance, and at the same time, the overall thickness is uniform and the welt is beautiful.
