Description

Technical Field

[0001] This utility model relates to the field of shoe upper ironing machinery and equipment. 。 Background Technology

[0002] In the shoe manufacturing process, upper making is a significant part of the process. Upper making includes attaching the upper to the shoe last, stretching and sewing the lining, etc. Figure 1 The shoe upper structure shown has the upper surface 10 and the backing 20 made separately. The upper surface 10 is put on the shoe last, which plays a shaping role. Then, the bottom edge of the upper surface 10 is pulled and bent until the bottom surface corresponds to the edge of the backing 20 and is sewn together. After the whole circle of sewing is completed, a shaped shoe upper that can be bonded to the sole is obtained.

[0003] In existing technologies, the shoe upper obtained after the upper is stitched together is not smoothed before being directly bonded to the sole. Smoothing here refers to smoothing the area around the stitched edge of the upper. Without this smoothing process, the edge of the upper is pulled inwards, resulting in noticeable wrinkles around the entire circumference. Shoes made with this condition can feel uneven to the foot when worn, causing discomfort for some individuals. Therefore, the inventors of this invention researched and conceived an improved solution to address these problems, leading to this invention. Utility Model Content

[0004] The purpose of this invention is to provide a pressing machine for flattening and ironing the bottom surface of slingback-backed shoe uppers, effectively addressing the problems existing in the background art. 。

The upper surface of the heating block is a flattened shape surface, which is constructed to adapt to the shape surface structure of the bottom surface of the shoe upper with a lining.

[0006] Furthermore, the shoe last connecting lifting device includes a drive cylinder assembly that extends and retracts downwards and a shoe last connector connected to the lower end of the piston rod of the drive cylinder assembly. The shoe last connector includes a fixed block and a movable block. The fixed block is fixedly connected to the lower end of the piston rod of the drive cylinder assembly, and the movable block is oscillatingly connected to the fixed block through a hinge structure.

[0007] Furthermore, an adjustment drive mechanism is provided between the fixed block and the movable block to adjust the swing angle of the movable block.

[0008] Furthermore, the pressing worktable is equipped with a positioning device, and the heating block is movably mounted on the positioning device, and the positioning position of the heating block can be adjusted by the positioning device.

[0009] Furthermore, the positioning device includes a placement base for placing the heating block and clamping and adjusting components provided on two opposite side walls of the heating block placed in the placement base. The clamping and adjusting components are adjusting bolts that pass through the mounting side walls of the placement base through a threaded engagement structure. The inner end of the adjusting bolt is provided with a tightening component for tightening the heating block.

[0010] Furthermore, the positioning device is connected to the pressing worktable via a rotating device that can adjust the positioning device.

[0027] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0028] This embodiment discloses a pressing machine for making a shoe upper with a lining, such as... Figure 2 and Figure 3 As shown, the main components include a pressing worktable 1, a heating block 2, a shoe last connecting lifting device 3, a positioning device 4, and a rotating device 5. It should be noted that, depending on specific requirements, an embodiment may also be provided that only includes the pressing worktable 1, the heating block 2, and the shoe last connecting lifting device 3, enabling the flattening and ironing of the sole of a specific shoe style. The mechanical equipment in this embodiment is more adaptable to the flattening and ironing of different shoe styles and uppers. Furthermore, the mechanical structure in this embodiment may also consist of the heating block 2, the shoe last connecting lifting device 3, the positioning device 4, and the rotating device 5 arranged in groups, with multiple groups corresponding to each other on the pressing worktable 1. The specific structural configuration and positional connection relationships of this embodiment will be described in detail below with reference to the accompanying drawings.

[0029] The pressing worktable 1 is typically a frame structure with high structural strength and stability, with an outer panel covering. The interior of the frame structure can provide space for the installation of mechanical structures and system components. A gantry mounting bracket is fixedly installed on the pressing worktable 1 for the fixed installation of the shoe last connecting lifting device 3. The heating block 2 is positioned on the pressing worktable 1 and below the shoe last connecting lifting device 3. The positioning device 4 is used to fix the heating block 2, and it is mounted on the pressing worktable 1 via a rotating device 5. The heating block 2 is electrically heated to form a component capable of ironing. The shoe last connecting lifting device 3 is used to fix and connect the shoe last with the upper lining and to move it up and down so that the bottom surface of the shoe upper contacts the heating block 2 for flat ironing. The positioning device 4 is used for positioning and fixing the heating block 2 on the pressing worktable 1. The installation of the positioning device 4 also allows the heating block 2 to be detachable and replaceable. The upper part of the heating block 2 is a flattening surface 21. Since the bottom surface of the shoe last (i.e., the bottom surface of the shoe upper) is usually not a flat surface, the flattening surface 21 must be constructed to adapt to the shape of the bottom surface of the shoe upper with a flattened backing. As shown in the figure, the flattening surface 21 is a concave arc shape with a similar outline to the bottom surface of the shoe upper and a large outline range. Specifically, the shape can be designed to adapt to the flattening of the bottom surface of the shoe upper. The rotating device 5 is used to adjust the movement of the heating block 2 during the flattening and ironing process. Since this embodiment has a more adaptable mechanical structure, the adjustment movement can make each block of the bottom surface of the shoe upper better contact the flattening surface 21 for flattening and ironing, thereby improving the adaptability of the flattening surface 21 on the heating block 2 to different shoe styles and sizes, so that the processing of this utility model is effective and reliable.

[0030] Since the bottom surface of the shoe last (i.e., the bottom surface of the shoe upper) is usually not a flat surface, especially around the seam where the upper is joined, this embodiment further improves the adaptability of contact during ironing and allows for self-adaptive adjustment between components. For example... Figure 4As shown, the shoe last connecting lifting device 3 includes a drive cylinder assembly 31 that extends downwards and a shoe last connector 32 connected to the lower end of the piston rod of the drive cylinder assembly 31. The shoe last connector 32 includes a fixed block 321 and a movable block 322. The fixed block 321 is fixedly connected to the lower end of the piston rod of the drive cylinder assembly 31. The movable block 322 is connected to the fixed block 321 by a hinge structure, allowing it to swing and move. By swinging and moving, it can receive relative pressure when in contact with the heating pressure block 2 and adaptively adjust the arc shape to fit the square, thereby achieving the above-mentioned effect. In another embodiment, the pressure in contact with the heating block 2 can be enhanced by actively adjusting the angle of the shoe last to achieve better flat ironing. This active adjustment can be achieved by further providing an adjustment drive mechanism (not shown in the figure) between the fixed block 321 and the movable block 322 to adjust the swing angle of the movable block 322. This can be implemented using existing swing control technology, such as a cylinder fixed to the fixed block 321. The outer end of the cylinder's piston rod is connected to the movable block 322 via a hinge structure, thus controlling the swing of the movable block 322 and adjusting the shoe last angle. The specific adjustment angle is set based on the study of the flat ironing trajectory. This is another technical solution, which will not be described in detail here.

[0031] The positioning device 4, such as Figure 5 As shown, the device includes a base 41 for placing the heating block 2 and clamping and adjusting components 42 corresponding to the two opposite side walls of the heating block 2 placed in the base 41. In this embodiment, the base 41 is a box-shaped structure with surrounding side walls and an open top, preventing accidental burns from workers. The clamping and adjusting components 42 are adjusting bolts 421 threaded onto the mounting side walls of the base 41. The inner end of the adjusting bolt 421 has a tightening component 422 for pressing against the side walls of the heating block 2. The tightening component 422 can be supported by a material with good damping effect and high temperature resistance. During positioning and adjustment, the heating block 2 can be positioned and clamped after being connected to the shoe last connecting lifting device 3 by adjusting the adjusting bolts 421 on both sides. This allows the heating block 2 to be movably mounted on the positioning device 4, and its positioning position can be adjusted via the positioning device 4. This adjustment structure is simple and easy to operate.

[0032] The rotating device 5 is usually driven by a motor, especially a forward and reverse motor, which can adjust the reciprocating motion of the heating block 2. The positioning device 4 can be installed and connected by a connecting plate connected to the output shaft of the motor, so as to achieve the effect of increasing the adaptive contact through the rotational motion, so as to better flatten and iron.

[0033] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
