Problems solved by technology

During vacuum suction, the mold is in the unfolded shoe shape state, that is, after the silicone film is covered on the unfolded shoe mold, the silicone film is completely attached to the mold by vacuum suction to form the unfolded shoe shape, and then heat-fixed and shaped. The silicone shoe shape made by the craft is in a flat state, and it needs to be assembled to make a three-dimensional shoe shape. The process is cumbersome, and there are seams on the upper after the stitching, which affects the appearance

Embodiment 1

[0051] A 3D vacuum shrinking device, including a shrinking assembly and a thermal fixing assembly; the shrinking assembly includes a base 1, a suction table 2, an elastic pad 3, a pressure plate 4 and a vacuum pump; the suction table 2 is located on the top of the base 1 , the shrinking table 2 is provided with a ventilation hole, the vacuum pump is arranged under the shrinking table 2, and is used to suck the air on the shrinking table 2 downward through the through hole 41, and the elastic pad 3 is located on the shrinking table 2. The upper part of the pressing plate 4 is movably covered on the upper part of the elastic pad 3. The pressing plate 4 is provided with a handle 43. The middle part of the pressing plate 4 is provided with a through hole 41 in the shape of a shoe sole. The through hole 41 is placed with a shoe The shoe body 5 of the last 6, the surface of the shoe body 5 is covered with a silicone sleeve, and the edge of the silicone sleeve is pressed between the p...

Embodiment 2

[0053] A method for processing a silicone shoe upper, comprising the following steps:

[0054] Step 1: Put the shoe last into the shoe body, and lay elastic pads on the suction table;

[0055] Step 2: Place the shoe body with the last on the upper part of the elastic pad;

[0056] Step 3: Cover the silicone film on the surface of the shoe body so that the edge of the silicone film extends to the upper part of the elastic sleeve;

[0057] Step 4: Press the pressure plate on the upper part of the elastic sleeve, so that the edge of the silicone film is completely sealed and fit between the elastic sleeve and the pressure plate;

[0058] Step 5: The vacuum pump draws out the air in the upper part of the vent hole, so that the silicone film and the surface of the shoe body are vacuum bonded;

[0059] Step 6: Control the heating box to slide horizontally relative to the shrinking platform, so that the shoe body enters the heating box, so that the silicone film is bonded to the th...

Embodiment 3

[0065] In the method for processing silicone shoe uppers in Example 2, the heating temperature in the heating box is 250° C., the vacuum pumping time is 35 s, and the time for the shoe body to enter the heating box is 20 minutes.

[0066] To sum up, the 3D vacuum shrinking equipment provided by the present invention is a special equipment designed based on the three-dimensional bonding of the silicone film on the surface of the shoe body, which can complete the three-dimensional vamp bonding of the silicone film at one time. The silicone film is absorbed and shaped by the 2D mold alone, and then assembled and attached to the surface of the shoe body, which simplifies the process and greatly improves work efficiency, and the 3D vacuum shrinking equipment makes the silicone film perfectly fit on the surface of the shoe body to avoid misalignment And the fitting seam affects the appearance of the shoe body, realizing the seamless fit of the silicone membrane. The rotatable struct...

Abstract

The invention relates to the technical field of shoe production, in particular to 3D vacuum suction shrinkage equipment and a silica gel vamp processing method. The equipment comprises a suction shrinkage assembly and a heat fixing assembly; the suction shrinkage assembly comprises a base, a suction shrinkage table top, an elastic cushion, a pressing plate and a vacuum pump; the suction shrinkagetable top is located on the upper portion of the base, the suction shrinkage table top is provided with a vent hole, the vacuum pump is arranged below the suction shrinkage table top and used for sucking air on the suction shrinkage table top downwards through the through hole, the elastic cushion is located on the upper portion of the suction shrinkage table top, the pressing plate movably coversthe upper portion of the elastic cushion, and a sole-shaped through hole is formed in the middle of the pressing plate; and a shoe body sleeved with a shoe tree is placed at the through hole, the surface of the shoe body is covered with a silica gel sleeve, and the edge of the silica gel sleeve is pressed between the pressing plate and the elastic cushion. According to the special equipment designed on the basis of the shoe body surface three-dimensional silica gel film laminating process, three-dimensional vamp silica gel film laminating can be completed at a time.

Description

technical field [0001] The invention relates to the technical field of footwear production, in particular to a 3D vacuum shrinking device and a processing method for silicone shoe uppers. Background technique [0002] For the processing technology of silicone uppers, some 2D vacuum suction machine structures have gradually appeared on the market. During vacuum suction, the mold is in the unfolded shoe shape state, that is, after the silicone film is covered on the unfolded shoe mold, the silicone film is completely attached to the mold by vacuum suction to form the unfolded shoe shape, and then heat-fixed and shaped. The silicone shoe shape produced by the craft is in a flat state, and it needs subsequent splicing to make a three-dimensional shoe shape. The process is cumbersome, and there are seams on the upper after splicing, which affects the appearance. Contents of the invention [0003] The technical problem to be solved by the present invention is: to provide a 3D v...
