Description

Technical Field

[0001] This utility model relates to the field of shoe processing technology, and more specifically, to a steam ironing device for the toe of a shoe with a lining. Background Technology

[0002] Lapel-stitched uppers, where the upper and lining are tightly sewn together using a lapel-stitching process, offer structural stability, a snug fit, and comfortable wear. They are widely used in the production of various footwear products, including casual shoes, work shoes, and outdoor shoes. The toe area, as the core visual and stress-bearing part of the upper, directly determines the appearance quality and wearing experience of the shoe due to its flatness and regularity. After lapel-stitching, the seam between the upper and lining is prone to defects such as toe protrusion, localized wrinkling, and uneven edges due to uneven tension, fabric shrinkage, or processing wrinkles. Without ironing, this not only results in a messy toe shape and affects the product's aesthetics but may also cause the toe to squeeze the toes during wear, reducing fit and comfort.

[0003] Currently, in order to reduce equipment investment costs, some companies in the industry use a method of placing the shoe upper directly on a steam pipe for ironing the toe of the lining-backed shoe upper. The specific operation process is as follows: the worker sets up the fixed metal steam pipe (with several steam outlets in the pipe) connected to the steam generator horizontally on the workbench; during the operation, the lining-backed shoe upper to be ironed is placed directly on the surface of the steam pipe with the toe facing down. The high temperature steam continuously output by the steam pipe softens the shoe upper fabric, and the fabric naturally stretches under its own weight. After the fabric cools down, the worker removes the shoe upper, completing the toe ironing operation.

[0004] In actual production, there may be some problems. Some equipment does not provide good support for the side of the shoe toe. During the steam process, the side of the shoe toe is prone to deformation due to lack of stable support. At the same time, the flow and efficiency of steam in the equipment is low, which not only affects the overall quality of the shoe toe ironing, but also prolongs the processing time of a single batch and reduces the efficiency of batch production, making it difficult to meet the actual production needs. Therefore, we urgently need a steam ironing device for shoe toe with a laminated lining to solve the above problems. Utility Model Content

[0005] One objective of this invention is to provide a new technology solution for a steam ironing device for the toe of a shoe with a lining. The device uses an arc-shaped support plate that slides along a sliding rod and is positioned in conjunction with a limiting hole to adapt to different toe sizes, thereby achieving stable support for the side of the toe, preventing deformation of the shoe upper when steam is applied, and ensuring a consistent toe shape.

[0006] According to a first aspect of the present invention, a steam ironing device for the toe of a shoe with a lining is provided, comprising a body for providing steam, and a steam pipe fixedly connected to the exhaust port of the body. A baffle for collecting steam is fixedly connected to the upper part of the body, and a support plate for supporting the toe is movably disposed on the steam pipe via an adjusting member.

[0007] Optionally, the steam pipe is provided with a first bracket for connecting the support plate. When the connection of the first bracket is engaged with the steam pipe by a buckle, the buckle is locked by bolts to form a positioning area.

[0008] Optionally, a screw is threadedly connected to the first bracket, a slider is threadedly connected to the screw, a first connecting rod is hinged at the connection of the slider, and the end of the first connecting rod is hinged to the support plate.

[0009] Optionally, the top end of the steam pipe is bolted to a second bracket, the connection of the second bracket is hinged to a second connecting rod, and the other end of the second connecting rod is hinged to a support plate.

[0010] Optionally, the support plate is provided with ventilation holes for air circulation.

[0011] Optionally, the support plate is symmetrically equipped with slide rods, and multiple sets of limiting holes are linearly opened on the slide rods along the axial direction. Arc-shaped support plates for supporting the side are slidably connected to the slide rods. When the positioning hole at the connection of the arc-shaped support plate is coaxial with the corresponding limiting hole, it is locked by bolts.

[0012] 1. According to one embodiment of the present disclosure, the steam ironing device for the toe of the shoe upper with a lining uses the cooperation of an arc-shaped support plate and a sliding rod to make the arc-shaped support plate conform to the curvature of the side of the toe. With the help of the linear sliding of the sliding rod and the positioning of multiple sets of limiting holes, it can adapt to the side support requirements of different sizes of shoe toes, avoid deformation of the shoe upper due to lack of stable support when steam is applied, effectively solve the problem of poor side support of the shoe toe, and ensure the consistency of the shoe toe shape.

[0013] 2. According to one embodiment of the present disclosure, the steam ironing device for the toe of the shoe upper with a lining is designed with vent holes and baffles. The vent holes on the support plate enable bidirectional steam penetration, avoiding insufficient steam accumulation on the inside of the toe. At the same time, the baffle on the upper part of the machine body prevents the steam from dissipating downwards, so that the steam gathers in the working area and forms a circulation, reducing steam waste, significantly improving steam circulation and efficiency, and shortening the single ironing processing time.

[0021] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0022] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0023] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0024] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0025] like Figure 1-4As shown, a steam ironing device for the toe of a shoe with a lining includes a body 1 for providing steam, and a steam pipe 2 fixedly connected to the exhaust port of the body 1. A baffle 3 for collecting steam is fixedly connected to the upper part of the body 1, and a support plate 4 for supporting the toe is movably arranged on the steam pipe 2 through an adjusting member.

[0026] Here, the machine body 1 is equipped with a high-power heating element and a steam-water separation device, which can quickly generate high-temperature and high-pressure steam. The steam temperature can reach 120℃ and the pressure can reach 0.8MPa. The steam output is stable, with a continuous output of up to 5kg / h, which can meet the steam demand of continuous ironing operations in batch production and avoid processing interruptions due to insufficient steam. The machine body 1 is equipped with an overpressure protection valve and a water shortage protection device. When the steam pressure exceeds the safety value or the water tank is short of water, the equipment will automatically stop and alarm, preventing explosion or dry burning damage due to excessive pressure and ensuring production safety.

[0027] Furthermore, the outer layer of the steam pipe 2 is wrapped with a rock wool insulation layer, which can effectively reduce the heat loss of steam during the transportation process and ensure that the steam reaching the support plate 4 area remains at a high temperature, avoiding the impact of temperature drop on the ironing effect.

[0028] Furthermore, the baffle 3 is fixed to the upper part of the machine body 1, forming a semi-enclosed space around the steam pipe 2 and the support plate 4, which can prevent steam from escaping to the lower part of the machine body 1 and the surrounding environment. According to actual tests, under the same steam output, the steam concentration in the working area is increased after adding the baffle 3, and the time for the shoe toe to reach the ideal ironing temperature is shortened. This not only improves the efficiency of a single processing cycle, but also reduces steam energy consumption and lowers production costs.

[0029] A first bracket 5 for connecting the support plate 4 is provided on the steam pipe 2. When the connection of the first bracket 5 is engaged with the steam pipe 2 by a buckle, the buckle is locked by a bolt to form a positioning area. A screw rod 6 is threadedly connected to the first bracket 5, and a slider 7 is threadedly connected to the screw rod 6. A first connecting rod 8 is hinged at the connection of the slider 7, and the end of the first connecting rod 8 is hinged to the support plate 4.

[0030] Here, the first bracket 5 engages with the steam pipe 2 via a buckle, allowing it to move axially along the steam pipe 2 without disassembly. Once in the correct position, it is secured with bolts. Due to variations in the thickness of the lining, the required height for the toe box varies; for example, a thicker lining requires a higher support height to avoid compression. The buckle, made of high-strength alloy, fits tightly to the steam pipe 2. After the bolts are tightened, a stable positioning area is formed, capable of withstanding the combined pressure from the support plate 4, the toe box, and steam impact. Long-term use will not result in loosening or shifting, ensuring precise and consistent support positioning.

[0031] Furthermore, rotating the screw 6 causes the slider 7 to move at a constant speed along the axis of the screw 6, which in turn pushes the support plate 4 to rotate around the hinge point via the first connecting rod 8, achieving stepless adjustment of the tilt angle, with an adjustment range of 0°-30°. Different styles of shoes have different toe tilt angles; for example, athletic shoes have a flatter toe, while leather shoes have a more upturned toe. Stepless adjustment allows the support plate 4 to fully conform to the curvature of the bottom of the toe, preventing slippage or compression when the toe is placed.

[0032] Furthermore, the screw 6 and the slider 7 are fitted with precision threads, and the thread helix angle is less than the friction angle, which has a self-locking function. After adjustment, no additional locking parts are needed, and the slider 7 will not move on its own due to external force, ensuring that the tilt angle of the support plate 4 remains unchanged during the ironing process and avoiding differences in ironing effect due to angle deviation.

[0033] The top end of the steam pipe 2 is bolted to a second bracket 9, and a second connecting rod 10 is hinged at the connection of the second bracket 9, and the other end of the second connecting rod 10 is hinged to the support plate 4.

[0034] Here, the second bracket 9 and the first bracket 5 form a two-point support, and the second connecting rod 10 and the first connecting rod 8 are connected to the support plate 4, so that the force on the support plate 4 is distributed to the two brackets, avoiding deformation or breakage of the support plate 4 caused by single-point support.

[0035] Furthermore, the second connecting rod 10 is hinged to the second bracket 9 and the support plate 4. When the support plate 4 adjusts its tilt angle by means of the screw 6, the second connecting rod 10 can rotate freely with the angle change without jamming or obstruction, ensuring a smooth adjustment process.

[0036] Furthermore, the second bracket 9 is connected to the steam pipe 2 via bolts. Removing the bolts allows the bracket, connecting rod, and support plate 4 to be removed as a whole, facilitating overall equipment maintenance or component replacement. For example, when the support plate 4 becomes worn, it can be quickly disassembled and replaced without disassembling core components such as the steam pipe 2, reducing maintenance downtime. Different shoe uppers may require support plates 4 of different sizes or materials; the detachable bolt connection allows the equipment to be compatible with various specifications of support plates 4. Simply replacing the support plate 4 and the matching connecting rod is sufficient to meet the ironing requirements of special shoe uppers, further enhancing the equipment's versatility.

[0037] The support plate 4 has ventilation holes 11 for ventilation.

[0038] Here, the ventilation holes 11 on the support plate 4 are evenly distributed in a matrix. Steam can penetrate from below the support plate 4 through the ventilation holes 11 to the inside of the toe, while external steam acts on the outside of the toe, forming a "pincer attack" steam action mode. Existing equipment can only achieve unilateral steam action, which easily leads to problems such as incomplete ironing and residual wrinkles on the inside of the toe.

[0039] Furthermore, the permeability of the vent 11 and the aggregation of the baffle 3 work together to allow steam to circulate within the semi-enclosed space through the vent 11, thus preventing localized steam accumulation or loss.

[0040] A sliding rod 12 is symmetrically installed on the support plate 4, and multiple sets of limiting holes 13 are linearly opened on the sliding rod 12 along the axial direction. An arc-shaped support plate 14 for supporting the side is slidably connected to the sliding rod 12. When the positioning hole on the connection of the arc-shaped support plate 14 is coaxial with the corresponding limiting hole 13, it is locked by bolts.

[0041] Here, the slide bar 12 has multiple sets of limiting holes 13 along its axis, and the arc-shaped support plate 14 can slide freely along the slide bar 12. It is coaxially locked with the positioning hole and different limiting holes 13, allowing for precise adaptation to various toe sizes, from children's shoes to adult shoes, and from narrow-toe shoes to wide-toe shoes. Compared to existing fixed support structures, there is no need to replace special support components for different styles of shoe uppers, reducing equipment changeover time and improving the flexibility of mass production.

[0042] Furthermore, the curved support plate 14 adopts an arc design that matches the curvature of the side of the toe, which can form a wrap-around support when in contact with the upper, dispersing the stress on the upper under the high temperature of steam.

[0043] Furthermore, the curved support plate 14 is locked to the sliding rod 12 with bolts, and can be quickly disassembled by loosening the bolts. During long-term use, the toe processing will generate fabric debris, glue residue, etc. The detachable design makes it easy to thoroughly clean the gaps of the support plate, avoiding residual impurities from affecting the quality of the subsequent shoe upper. It also facilitates the individual replacement of the support plate after it wears out, reducing maintenance costs.

[0044] In this invention, firstly, the machine body 1, which provides steam, is started. The steam generated by the machine body 1 is transported to the work area through the steam pipe 2, which is fixedly connected to its exhaust port. At the same time, the baffle 3, which is fixedly connected to the upper part of the machine body 1, can prevent the steam from diffusing downwards from the machine body 1, so that the steam accumulates in the work area. Before the steam is transported, the support plate 4, which supports the toe, can be adjusted by adjusting the fasteners and bolts of the first bracket 5. Specifically, the height of the support plate 4 on the steam pipe 2 is adjusted by using the buckle and bolts of the first bracket 5. The slider 7 is moved by rotating the screw 6 on the first bracket 5. Then, the first connecting rod 8 is used to push the support plate 4 to rotate around the hinge point of the second bracket 9 and the second connecting rod 10 to adjust the tilt angle of the support plate 4. The arc-shaped support plate 14 can also slide along the sliding rod 12 on the support plate 4. After the positioning hole of the arc-shaped support plate 14 is coaxial with the limiting hole 13 of the sliding rod 12, it is locked with bolts to achieve the adaptation support for the side of the toe. Once the support plate 4 is adjusted into place and the toe is positioned, the steam circulates within the work area under the action of the baffle 3. Some of the steam acts directly on the inside of the toe through the ventilation holes 11 on the support plate 4, while some of it comes into full contact with the surface of the toe, thus completing the steam ironing operation of the toe.
