Description

Technical Field

[0001] This utility model relates to the field of heel shaping machine technology, and more specifically to a heel shaping machine that is convenient for clamping shoe uppers. Background Technology

[0002] During shoe production, the heel needs to be shaped to give it a certain curvature, facilitating connection with other components and maintaining an aesthetically pleasing appearance. In the heel shaping process, the shoe material is typically placed on a mold, and then pressed down using a cold mold. However, shoe sizes vary widely in production, making the clamping of different sized uppers a crucial step in heel shaping. The upper must be clamped and flattened during heel shaping to prevent wrinkles, which would affect the shaping effect and the overall quality of the shoe. Existing shaping machines typically only clamp the upper and cannot stretch it according to different sizes, presenting a limitation. Furthermore, current heel shaping machines usually only have a cold pressing station, but a heat softening process is required before cold pressing to soften the upper for easier subsequent cold pressing. Therefore, existing heel shaping machines are functionally limited and not practical enough. In response to this, the inventor has proposed a heel shaping machine that facilitates clamping of shoe uppers. By setting up dual hot and dual cold workstations in the shaping machine, and installing shoe upper clamping devices at the workstations, the shoe uppers can be quickly clamped and straightened, facilitating heat softening and cold shaping of the shoe uppers. The machine has a high level of integration, making it easy for workers to operate and improving the quality of shoe processing.

[0003] To effectively clamp shoe uppers of different sizes, facilitate cold pressing and shaping of the heel, and improve shoe manufacturing efficiency and quality, Chinese Patent (Authorization Announcement No.: CN221616390U) discloses a convenient heel shaping machine. This utility model includes a connecting frame, a worktable, a shaping mold, a fixing base, an airbag, and a clamping plate. It also includes an adjustment component mounted on the worktable to change the distance between the clamping plate and the shaping mold; a movable plate fixedly mounted below the clamping plate; a fixed frame fixedly mounted on the worktable; a limiting plate fixedly connected to the movable plate, extending its bottom into the fixed frame; limiting grooves evenly distributed on both sides of the limiting plate; a limiting block, its top penetrating the fixed frame and movably installed into the limiting groove; mounting holes on both sides of the fixed frame; a bracket fixedly mounted on both sides of the fixed frame; and a return spring fixedly connected to the limiting block and the bracket. This utility model, through the setting of the limiting plate and the limiting block, changes the distance between the clamping plate and the fixing base, facilitating the fixing of shoes of different sizes and improving shoe maintenance.

[0004] The proposed solution still has some shortcomings in its application. When shaping the heel, the entire upper needs to be clamped and stretched; otherwise, wrinkles can easily occur, especially since shoes come in different sizes with varying upper dimensions. Furthermore, during cold-pressing of the heel, the upper requires a heat-softening step, particularly for shoes with harder upper materials. Therefore, the heel shaping machine needs to have both heat-softening and cold-setting stations. This necessitates improvements to the machine's clamping structure to allow for overall clamping of the upper while also straightening it according to different sizes, thus improving shaping quality and overall practicality. Utility Model Content

[0005] This utility model discloses a heel shaping machine that facilitates clamping of shoe uppers, and its main purpose is to overcome the above-mentioned shortcomings and disadvantages of the existing technology:

[0006] The technical solution adopted in this utility model is as follows:

[0007] A heel shaping machine for convenient clamping of shoe uppers includes a main body. The main body has cold pressing and shaping stations on its left and right sides and a hot softening station in the middle. Both the cold pressing and shaping stations and the hot softening station have a retractable shaping mechanism at their rear sides. A shoe heel mold is located at the front of the retractable shaping mechanism. A groove is located at the front of the shoe heel mold, and a clamping device is installed in the groove. A shoe upper covering block is located in the middle of the clamping device. First telescopic cylinders are located on the left and right sides of the shoe upper covering block. A moving rod is installed in the middle of the driving end of each first telescopic cylinder, and a clamping block is installed at the top of the moving rod. A base is located at the bottom of the shoe upper covering block, and a second telescopic cylinder is installed at the rear of the base. The second telescopic cylinder can drive the base to move back and forth.

[0008] Furthermore, the shoe upper covering block has a first arc-shaped structure on both the left and right sides, and the outer side of the first arc-shaped structure is adapted to cover the shoe upper.

[0009] Furthermore, the clamping block has a second arc-shaped structure towards the center, which is adapted to clamp the first arc-shaped structure.

[0010] Furthermore, rubber surfaces are provided on the outer side of the first arc-shaped structure and the inner side of the second arc-shaped structure respectively.

[0011] Furthermore, there are two clamping blocks and two telescopic cylinders arranged symmetrically. The clamping blocks can move left and right along the shoe cover block via the first telescopic cylinder.

[0012] Furthermore, a control switch is provided on the front side of the clamping device, which is connected to the control of the first telescopic cylinder and the second cylinder.

[0013] Furthermore, a foot switch is provided at the bottom of the device body, which is connected to the retractable shaping mechanism.

[0014] As can be seen from the above description of this utility model, compared with the prior art, the advantages of this utility model are as follows:

[0015] This invention firstly incorporates a dual cold-pressing and shaping station and a dual hot-softening station on the equipment body, allowing for pre-heat softening followed by cold-pressing shaping of the shoe upper, resulting in a better shaping effect. Furthermore, the dual-hot and dual-cold four-station setup effectively improves processing efficiency and reduces worker waiting time for the equipment to start. The design is ingenious and highly practical. Next, a clamping device is installed at the front of the cold-pressing and shaping station and the hot-softening station. First, the shoe upper is fixed to the heel mold using the shoe upper covering block, and then the clamping block clamps the forefoot area of ​​the shoe. The upper is stretched and straightened by a second telescopic cylinder to prevent wrinkles at the heel, which would affect the heat-softening and cold-pressing effects. This also solves the problem of inconsistent upper sizes making automatic straightening inconvenient. Finally, both the outer side of the upper covering block and the inner side of the clamping block have an arc-shaped structure, which facilitates the natural wrapping of the upper. The arc-shaped structure also has a rubber surface, which can improve friction and better clamp the upper. This utility model has a novel structure and ingenious design. The integrated heat-cold pressing design provides good heel shaping and effectively improves processing efficiency, making it suitable for widespread application. Attached Figure Description

The second telescopic cylinder 13 can drive the base 12 to move back and forth.

[0021] Furthermore, the shoe upper covering block 8 has a first arc-shaped structure 81 on both the left and right sides, and the outer side of the first arc-shaped structure 81 is adapted to cover the shoe upper.

Then, the second telescopic cylinder 13 is activated, which drives the clamping device 7 to move forward, tightening the shoe upper and preventing wrinkles at the heel. Finally, the retractable shaping mechanism 4 is activated by the foot switch 16 to move forward and fit against the heel mold 5 to heat soften the shoe upper at the heel. After heat softening, the shoe upper at the heel is cold-pressed and shaped in the cold pressing and shaping station 2 in the same manner as described above.
