Abstract:
A three-dimensional measurement (C) system for a marked line for adhering a sole (A) to an upper (B) and a three-dimensional measurement method therefor. A three-dimensional structure of a sole inner surface (A1) is measured automatically using a three-dimensional scanner (30), so as to form three-dimensional inner surface data (201) of the sole (A); and by conducting operation processing on the three-dimensional inner surface data (201) of the sole (A) and three-dimensional surface data (202) of the upper (B), a contour line (A2) of the sole inner surface (A1) is transferred to an upper lower surface (B1), so as to form a processing marked line of the upper (B), thereby improving the operation efficiency of adhering the sole (A) to the upper (B).

Abstract:
A pretreatment method for application of coating to shoe parts is capable of replacing the conventional primer coating process with the UV radiation process. The coating pretreatment to the shoe parts can be carried out continuously in an automatic manner. Besides, creating etching effect by using UV-C radiation and ozone activating improves the bonding of the shoe parts to the adhesives, without substantial increase in equipment cost. A pretreatment system for application of coating to shoe parts can be provided with more reaction chambers for UV-C radiation and cleaning, so as to increase the breadth of application of the UV radiation system. Subjecting the surface of the shoe parts to UV-C radiation and cleaning process more than one time can activate the surface, and improve the follow-up coating quality.
Abstract:
A method for applying hot melt adhesive powder onto a sole or shoe part includes the steps of applying a cleaning agent, irradiating, applying a conductive liquid which has a conductivity at least 100 times higher than purified water which has a conductivity of 5.5.10−6 S/m, spraying hot melt adhesive powder; and heating. The method can save energy, reduce the working space, reduce the labor intensity and improve the working environment by making the spraying and the melting operation of the hot melt adhesive carry out automatically.

Abstract:
A method for manufacturing a mold for forming three-dimensional embossments on a surface of a shoe part, comprising: making a high-resolution template with a texture structure; using the high-resolution template to make a high-resolution pattern mold, forming a boundary wall inside the mold through the texture structure; defining, by the boundary wall, different regions provided for being filled with polyurethane compositions of different colors.
Abstract:
Provided are an automatic spray system for a shoe sole adhesive and a spray method therefor, wherein a spray gun and a coating tool are provided at the end of a mechanical arm, enabled to be located in an adhesive spray path, and respectively arranged at the inner and outer sides of a contour side line of the top face of a shoe sole, and by cooperating with the scan information of the top face of the shoe sole and the position information of the shoe sole read by a computer, the adhesive spray region of the spray gun slightly exceeds the contour side line of the top face of the shoe sole and overlaps with a cementing region at the top face of the shoe sole such that a large part of the adhesive is sprayed onto the cementing region, and a small part of the adhesive exceeding the contour side line is blocked and adsorbed by the coating tool, whereby the technical effects of automatically and accurately cementing the shoe sole, preventing the adhesive from overflowing and staining the shoe sole appearance, increasing the bonding strength between the shoe sole and the vamp by uniformly coating the adhesive etc.

Abstract:
Disclosed is a vamp 3D-printing system. Mainly, by using a 3D-printing device comprising at least one fixed printing head and a rotatable printing head, printable materials are overlapped and printed on a vamp assembly by means of cooperation of the fixed printing head and the rotatable printing head according to a preset printing program of a computer. In this way, the technical effects are achieved that vamp pattern styles having thick and thin line changes and high precision of printing positions are printed by using more two printing heads; in addition, manufacturing costs are actually reduced and manufacturing procedures are actually simplified by applying the 3D-printing technology to printing of vamp pattern styles.
