Description

Technical Field

[0001] The invention relates to the technical field of shoe and clothing manufacturing, and in particular to a rope-type seamless welding wrapping support process. Background Art

[0002] Shoes are a clothing accessory whose task is to protect and wrap the user's feet. They are basically composed of a sole and an upper. The sole is the lower part that contacts the ground, while the upper is the part set above the sole. The upper can wrap the user's foot and connect to the sole to fix the sole on the user's foot to prevent the sole from falling off. The setting of the upper can effectively improve the integrity of the shoe and foot, and make the shoe better protect the foot.

[0003] Although the above-mentioned existing technology can solve the corresponding technical problems, it still has certain defects: when the uppers produced by the existing upper manufacturing process are used in high-intensity sports involving lateral movement, such as basketball, when pushing off the ground sideways, the uppers are easily subjected to great lateral forces and become twisted and deformed, and then cannot hold the foot, causing the foot to excessively stretch outward and tilt, which is prone to ankle sprains. At the same time, after repeated lateral pushing off movements, the repeated twisting and deformation of the upper can easily cause the upper to be stretched and loose, which greatly reduces the wrapping of the upper and affects the service life of the upper. Summary of the Invention

[0004] The purpose of the present invention is to address the defects and shortcomings of the existing technology and provide a rope-type seamless welded wrapping support process with good finished product wrapping, strong lateral support and long service life.

[0005] To achieve the above object, the present invention adopts the following technical solution: a rope-type seamless welding wrapping support process, comprising the following steps:

[0006] Step 1: Mesh cutting: laying the mesh on a flat surface and cutting the mesh into the shape and size required for the upper to obtain a mesh sheet shaped like the upper;

[0007] Step 2: Lay out the mold, fix the front of the shoe upper mesh piece on the flat plate, and set the rope mold on top of it;

[0008] Step 3: Laying the rope, passing the rope through the mold laid on the shoe upper-shaped mesh cloth, so that the rope passes through the rope mold and is laid on the shoe upper-shaped mesh cloth piece;

[0009] Step 4: Fix the rope, use the threading device to thread the rope laid on the shoe upper-shaped mesh cloth, so that the rope is fixed on the shoe upper-shaped mesh cloth, and remove the rope mold;

[0010] Step 5: Set the reinforcement layer. Take out the mesh after sewing, turn it upside down on a flat plate, and lay the reinforcement layer on the mesh. Then use a hot pressing device to seamlessly hot-press the reinforcement layer to the reverse side of the mesh, and then cut the excess reinforcement layer fabric.

[0011] The reinforcement layer is provided by taking out the stitched mesh piece, turning it upside down on a flat plate, and laying the reinforcement layer on the mesh piece. The reinforcement layer is then hot-pressed and fixed to the reverse side of the mesh piece by a hot-pressing device. The seamless hot-pressing protective layer is then applied to the front side of the mesh piece at the toe and eyelet positions.

[0012] The reinforcement layer is provided by taking out the stitched mesh sheet, placing it upside down on a flat plate, and laying the reinforcement layer on the mesh sheet. The reinforcement layer is then seamlessly hot-pressed and fixed to the reverse side of the mesh sheet by a hot pressing device, and the excess reinforcement layer fabric is then cut. The reinforcement layer is previously punched to form a plurality of through-holes for ventilation.

[0013] The seamless hot pressing temperature is 240° C. for the upper mold and 140° C. for the lower mold, and the seamless hot pressing time is 55 seconds.

[0014] A further improvement is that: the protective layer is a PU layer.

[0015] A further improvement is that the seamless hot pressing protective layer is formed on the front of the mesh sheet, and then a seamless hot pressing protective film is formed on the edge of the protective layer. The seamless hot pressing temperature is 240°C for the upper mold and 140°C for the lower mold, and the seamless hot pressing time is 55 seconds.

[0016] A further improvement is that the protective film is a thermal film.

[0017] A further improvement is that the ventilation holes are arranged on the reinforcing layer at the toe and the side of the shoe.

[0018] A further improvement is that the mesh is a woven single-layer mesh with upper yarn-shedding prevention.

[0019] A further improvement is that the rope is a round shoelace with a hot-melt wire added.

[0020] A further improvement is that: the reinforcing layer is a warp-knitted single-layer mesh fabric.

[0021] After adopting the above technical solution, the beneficial effects of the present invention are as follows: during the production process of the present invention, a seamless hot-pressed reinforcement layer of the mesh is adopted and simultaneously cooperated with a rope arranged on the side of the mesh, so that the finished product can effectively wrap the foot. At the same time, when performing violent lateral pushing, the rope can greatly enhance the lateral support force of the finished shoe upper to hold the user's foot, avoiding excessive lateral extension of the foot and spraining the ankle. At the same time, after multiple lateral pushing, the elastic reinforcement layer is combined with the draw rope to prevent the mesh from loosening, ensuring the wrapping while greatly improving the service life of the shoe upper.

Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0023] Figure 1 1. It is a schematic flow chart of the wrapping support process of the rope-type seamless welding of the present invention; DETAILED DESCRIPTION

[0024] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0025] See Figure 1 As shown, the technical solution adopted in this specific embodiment is: a rope-type seamless welding wrapping support process, including the following steps:

[0026] Step 1: Mesh cutting: laying a mesh on a flat surface. The mesh is a single-layer woven mesh with yarn-shedding resistance, and cutting the mesh into the shape and size required for the upper to obtain a mesh sheet in the shape of an upper.

[0027] In this embodiment, the mesh is first placed on a flat surface of a workbench, and then the mesh is cut into the required shoe upper shape by a cutting machine or manual cutting according to the required mesh size, which is convenient for subsequent processing. At the same time, the use of a single-layer woven mesh with anti-striping yarn ensures that the mesh is breathable while preventing attachments from falling off.

[0028] Step 2: Lay out the mold, fix the front of the shoe upper mesh piece on the flat plate, and set the rope mold on top of it;

[0029] In this embodiment, the cut mesh is fixed on the flat surface of the workbench, and the rope winding mold is set above the mesh, so that the rope can be placed on the upper surface of the mesh more accurately and quickly;

[0030] Step 3: Laying the rope, which is a round shoelace with hot-melt thread, and passing the rope through a mold laid on the shoe upper-shaped mesh cloth to make the rope pass through the rope mold and fit on the shoe upper-shaped mesh cloth;

[0031] In this embodiment, a rope mold is used to quickly place the rope on the upper surface of the mesh, making the rope symmetrical on both sides. At the same time, the rope is wound straight and tighter to avoid bending that affects the wrapping effect. The use of round shoelaces with added hot melt wire makes the rope stronger and more tensile. At the same time, different pigments can be mixed into the rope to obtain different colors to improve the aesthetics. If the shoe surface requires high lateral support and a certain degree of lightweight, the rope can be installed only on the forefoot side and the back waist side of the upper mesh, maintaining support performance while reducing weight.

[0032] Step 4: Fix the rope, use the threading device to thread the rope laid on the shoe upper-shaped mesh cloth, so that the rope is fixed on the shoe upper-shaped mesh cloth, and remove the rope mold;

[0033] In this embodiment, the threading machine can be used to quickly thread the ropes laid on the surface of the mesh, thereby improving automation and making the threading more accurate. The threading can also be used to firmly fix the ropes on the mesh to enhance the strength of the mesh.

[0034] Step 5: Setting a reinforcement layer, which is a single-layer warp-knitted mesh. Take out the stitched mesh piece, turn it upside down on a flat plate, and lay the reinforcement layer on the mesh piece. Then, use a hot pressing device to seamlessly hot-press the reinforcement layer onto the reverse side of the mesh piece, and then cut off the excess reinforcement layer fabric.

[0035] In this embodiment, the mesh sheet after the stitching rope is fixed is inverted and placed on a flat plate of a workbench. Then, the TPU hot melt adhesive film is laid on the mesh sheet, and the reinforcing layer is covered on the mesh sheet after the TPU hot melt adhesive film is laid. Then, the reinforcing layer is seamlessly hot-pressed onto the mesh sheet through the TPU hot melt adhesive film by a hot pressing device, so that the mesh sheet is supported by the reinforcing layer. The reinforcing layer uses a single-layer warp-knitted mesh, which effectively improves the tactile feel when the foot contacts the reinforcing layer, while maintaining a certain degree of breathability and support tensile strength.

[0036] The reinforcement layer is provided by taking out the stitched mesh piece, placing it upside down on a flat plate, and laying the reinforcement layer on the mesh piece. The reinforcement layer is then hot-pressed and fixed to the back of the mesh piece by a hot-pressing device. A seamless hot-pressed protective layer is then formed on the front of the mesh piece at the toe and eyelet positions. The protective layer is a PU layer, which is beneficial for providing additional support to the toe position through the high flexibility of the PU layer and making the toe more resistant to pressure, thereby preventing the shoe upper from collapsing and providing protection for the foot when the shoe upper is stepped on. At the same time, the PU layer is also provided at the eyelet position, so that the taut shoe upper is not easily damaged after being tightened by the shoelaces, and the upper has better tensile strength at the eyelet when wearing and moving;

[0037] The seamless hot-pressed protective layer is formed on the front of the mesh sheet, and then a seamless hot-pressed protective film is formed on the edge of the protective layer. The protective film is a thermal adhesive film, which is conducive to compacting and fixing the edge of the protective layer, preventing the protective layer from warping and falling off after a period of use and making the overall appearance more beautiful.

[0038] The reinforcement layer is provided by taking out the stitched mesh sheet, placing it upside down on a flat plate, and laying the reinforcement layer on the mesh sheet. The reinforcement layer is then seamlessly hot-pressed and fixed to the reverse side of the mesh sheet using a hot pressing device, and the excess reinforcement layer fabric is then cut. The reinforcement layer is previously punched to form a plurality of through-holes, which helps to reduce the overall weight of the shoe upper, making it thinner and lighter, while enhancing the breathability of the shoe upper.

[0039] The ventilation holes are provided on the reinforcing layer at the toe and the side of the shoe, which is beneficial for ensuring breathability while avoiding affecting the supporting performance of the reinforcing layer;

[0040] The seamless hot pressing temperature is 240° C. for the upper mold and 140° C. for the lower mold, and the seamless hot pressing time is 55 seconds, which is conducive to achieving a better seamless hot pressing fixed connection effect.
