Embodiments of the present invention are described below in conjunction with fig. 1-5.
Referring to fig. 1, an embodiment of the present invention provides a hot-press reverse-wrapping process for a heel counter, which includes the following steps:
s100, providing raw materials and an outer shoe piece 120 for standby, wherein one surface of the outer shoe piece 120 is provided with a cotton piece;
s200, placing raw materials on a parting surface of a first forming die, closing the first forming die, hot-pressing the raw materials and preserving heat for a first time to obtain a hot-pressed semi-finished product;
S300, thinning the upper edge of the cotton piece, attaching and sewing the upper edge of the outer shoe piece 120 with the edge of the shoe mouth of the hot-pressed semi-finished product;
s400, turning the sewn outer shoe piece 120 upwards to the rear end of the hot-pressed semi-finished product, and attaching the cotton piece to the rear surface of the hot-pressed semi-finished product to obtain a shoe counter rough blank;
s500, placing the shoe heel upper rough blank on a parting surface of a second forming die, and closing the second forming die;
And S600, hot-pressing the shoe heel counter rough blank and preserving heat for a second time to obtain a finished shoe heel counter.
In step S100, the outer shoe 120 may be connected to the cotton sheet by means of adhesive such that the cotton sheet is attached to one side of the outer shoe 120. The cotton sheets serve to connect the outer shoe sheet 120 and the hot-press half product, and to some extent, the thickness of the rear surface of the shoe counter blank can be increased so as to change the pattern and shape of the rear surface of the shoe counter blank by hot-pressing. The style of the first forming die can be adaptively modified and adjusted according to actual production requirements.
Referring to fig. 2, the heel counter hot-press reverse-wrapping molding process further includes the following steps, before the step of bonding and sewing the upper edge of the outer shoe sheet 120 with the welt edge of the hot-press semi-finished product:
and S700, providing a cutting tool for standby, and cutting the upper edge of the hot-pressed semi-finished product by the cutting tool.
Before the upper edge of the outer shoe 120 is attached to the upper edge of the front end of the hot-pressed semi-finished product, the upper edge of the hot-pressed semi-finished product is cut by a cutting tool, so that the hot-pressed semi-finished product forms the shape of a shoe mouth required by a shoe heel, and the outer shoe 120 is matched with the arrangement of the outer shoe 120, and the outer shoe 120 can cover the notch at the upper edge of the hot-pressed semi-finished product after being reversely wrapped, so that the problem that the notch is scratched to a human body is avoided. The cutting tool may be scissors, a cutter, etc.
After the finished shoe heel counter is manufactured in the step S600, the lower edge and the side edges of the finished shoe heel counter are sheared by a cutting tool. The finished shoe heel counter after the twice hot press molding is cut by a cutting tool, so that the finished shoe heel counter forms a preset shape, and the shoe heel counter is matched with the shoe front upper and the shoe sole to realize the connection of the shoe body.
Referring to fig. 2, the hot-pressing and reverse-wrapping forming process for shoe counter provided by the embodiment of the invention further comprises the following steps before the step of thinning the upper edge of the cotton piece:
And S800, trimming the upper edge of the outer shoe piece 120 so that the upper edge of the outer shoe piece 120 is matched with the edge of the shoe mouth of the hot-pressed semi-finished product.
Before the upper edge of the cotton piece is thinned, the upper edge of the outer shoe piece 120 is trimmed, so that the upper edge of the outer shoe piece 120 is matched with the edge of the shoe mouth of the hot-pressed semi-finished product, such as the upper edge of the trimmed cotton piece is thinned by an external peeling machine, the upper edge of the outer shoe piece 120 can be tightly attached to the upper edge of the hot-pressed semi-finished product, and the thinned part of the cotton piece just corresponds to the edge of the shoe mouth of the hot-pressed semi-finished product after the outer shoe piece 120 is turned backwards, so that the problem that the shoe mouth of the shoe rear upper blank is thickened due to the blocking effect of the cotton piece is avoided.
Referring to fig. 3, in step S400, the step of bonding the cotton sheet to the rear surface of the hot-pressed semi-finished product further includes the steps of:
and S410, bonding the cotton sheets to the rear surface of the hot-pressed semi-finished product, and adjusting the relative position relationship between the cotton sheets and the hot-pressed semi-finished product in a manual pressing mode and keeping the cotton sheets tightly bonded to the rear surface of the hot-pressed semi-finished product.
S420, sewing the left edge of the outer shoe plate 120 and the left edge of the hot-pressed semi-finished product into a whole, namely sealing the left opening of the shoe counter rough blank, which is beneficial to keeping the connection stability between the outer shoe plate 120 and the hot-pressed semi-finished product.
S430, sewing the right edge of the outer shoe plate 120 and the right edge of the hot-pressed semi-finished product into a whole, namely sealing the right opening of the shoe heel counter blank, which is beneficial to keeping the connection stability between the outer shoe plate 120 and the hot-pressed semi-finished product.
S440, sewing the lower edge of the outer shoe 120 and the lower edge of the hot-pressed semi-finished product into a whole. Namely, the lower end opening of the shoe counter rough blank is sealed, which is beneficial to keeping the connection stability between the outer shoe plate 120 and the hot-pressed semi-finished product.
The hot-pressing reverse wrapping and forming process of the shoe counter enables the outer shoe plate 120 to be tightly connected with the hot-pressing semi-finished product in a sewing and sealing mode, and is beneficial to avoiding the occurrence of the problem that the positions of the outer shoe plate 120 and the hot-pressing semi-finished product deviate or wrinkles are generated in the hot-pressing process of the shoe counter blank.
Compared with the process that the cotton piece is required to be stuck on the rear surface of the hot-pressed semi-finished product by hand, the glue is sprayed on the cotton piece, and after the cotton piece is heated by the external heating equipment, the glue of the cotton piece is melted, and then the outer shoe piece 120 is turned backwards and is attached to the cotton piece.
The hot-pressing reverse-wrapping forming process for the shoe counter provided by the embodiment of the invention is beneficial to saving the process of additionally bonding the cotton piece with the rear surface of the hot-pressing semi-finished product by bonding the cotton piece with the outer shoe piece 120, and is beneficial to avoiding the problem that the thickness of the shoe mouth of the shoe counter blank after reverse wrapping is thickened by thinning the cotton piece, and the outer shoe piece 120 is connected with the hot-pressing semi-finished product by sewing and sealing the left side edge, the right side edge and the lower side edge, so that the problem that the cotton piece needs to be heated by an external heating device is avoided, and the glue attached on the cotton piece can be connected with the outer shoe piece 120 after melting is solved.
Referring to fig. 4, the hot-pressing reverse-wrapping process for the shoe heel counter provided by the embodiment of the invention can effectively save the production cost of shoe heel counter preparation compared with the process of independently pasting cotton on the rear surface of the shoe heel counter.
In step S200, the raw materials include a lower sponge sheet, a supporting elastic sheet 200, an inner shoe sheet 110, a welt reinforcing sheet, a shoe body reinforcing sheet, and a buffer sheet. Placing raw materials on a parting surface of a first forming die, closing the first forming die, hot-pressing the raw materials and preserving heat for a first time to obtain a hot-pressed semi-finished product, and comprising the following steps:
