Description

Technical Field

[0001] This utility model relates to the field of heel shaping machine technology, and more specifically to a shoe body limiting component applied to a heel shaping machine. 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. Existing shaping machines usually clamp the heel area of ​​the shoe upper, but this method easily leads to wrinkles in the upper during actual operation, resulting in poor heel shaping. Furthermore, current heel shaping machines on the market typically only have a cold pressing station, but some shoes require heat softening before cold pressing. Softening before shaping yields better results, highlighting the limitations of existing heel shaping machines. In response to this, the inventors have proposed a shoe body limiting component for use in a heel shaping machine. By setting up a dual-station system of softening and cold pressing in the shaping machine, the shoe upper can be softened and shaped in one go. At the same time, the shoe upper can be clamped and limited to keep it taut, which facilitates shaping and improves the quality of shoe processing.

[0003] To effectively clamp and limit shoe uppers of different sizes, facilitate cold pressing and shaping of the heel, and improve processing 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 fixed 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 fixed base, facilitating the fixing of shoes of different sizes and improving shoe stability.

[0004] The solution still has some shortcomings in application. Since the upper is usually already formed when the heel is being shaped, that is, the forefoot part of the upper is already formed. It is necessary to maintain the shape of the forefoot part, otherwise it will affect the processing efficiency and quality of the shoe. In addition, the clamping and limiting method also needs to be considered. Using spring clamping may not have an ideal clamping effect and may cause the upper to slip. Therefore, the shoe body limiting component structure of the heel shaping machine needs to be improved so that it can effectively clamp the upper as a whole, while maintaining the shaping effect of the forefoot part of the shoe, which facilitates the integrated operation of the shoe, that is, softening cold pressing shaping. Utility Model Content

[0005] This utility model discloses a shoe body limiting component applied to a heel shaping machine, the main purpose of which is to overcome the above-mentioned shortcomings and disadvantages of the prior art:

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

[0007] A shoe body limiting component for a heel shaping machine includes a device body. The device body includes a heat softening station on the left and a cold pressing shaping station on the right. Both the heat softening station and the cold pressing shaping station are provided with a heel mold at their upper parts. The upper part of the heel mold is adapted to be provided with a retractable heat softening mold and a retractable cold pressing shaping mold, respectively. Both the heat softening station and the cold pressing shaping station are provided with a retractable limiting seat at their lower parts. A foot mold is provided in the middle of the retractable limiting seat. An inflatable seat is installed around the foot mold. An air bladder is provided inside the inflatable seat. A rubber patch is provided on the inner side of the air bladder. The rubber patch is attached to the foot mold.

[0008] Furthermore, the top of the retractable heat softening mold and the retractable cold pressing mold are equipped with a first telescopic cylinder.

[0009] Furthermore, a second telescopic cylinder is installed at the lower part of the telescopic limiting seat, which can drive the telescopic limiting seat to move up and down.

[0010] Furthermore, a hot air hood is installed on the front side of the retractable heat softening mold.

[0011] Furthermore, the inflation seat has an inflation / deflation port on one side, which is connected to an external air pump.

[0012] Furthermore, an infrared rangefinder is installed on one side of the bottom of the retractable limiting seat.

[0013] 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:

[0014] This invention first integrates a heat softening station and a cold pressing station on the equipment body, allowing for the combined heat softening and cold pressing of the shoe upper. This results in better heel shaping. The integrated design of the heat softening and cold pressing stations also effectively improves processing efficiency and reduces worker waiting time. Next, the heel of the shoe upper is fixed using a retractable heat softening mold and a retractable cold pressing mold. Then, the airbag on the retractable limiting seat at the front of the heat softening and cold pressing stations inflates, causing the rubber patch to contact the foot mold. The upper is clamped to the forefoot area of ​​the shoe, and then 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 shoe sizes and difficulty in positioning the upper. Finally, an infrared rangefinder is installed at the bottom of the telescopic positioning seat, which can move the telescopic positioning seat precisely according to different shoe sizes, avoiding movement that is too far or too close and affects the straightening of the upper. It is highly practical. This utility model has a novel structure, ingenious design, integrated heat and cold pressing design, good shaping effect, high processing efficiency, and is suitable for widespread application.

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0020] like Figures 1 to 4 As shown, a shoe body limiting component applied to a heel shaping machine includes a device body 1. The device body 1 includes a heat softening station 2 on the left and a cold pressing shaping station 3 on the right. Both the heat softening station 2 and the cold pressing shaping station 3 are provided with a shoe heel mold 4 at their upper parts. The upper part of the shoe heel mold 4 is adapted to be provided with a retractable heat softening mold 5 and a retractable cold pressing shaping mold 6, respectively. Both the heat softening station 2 and the cold pressing shaping station 3 are provided with a retractable limiting seat 7 at their lower parts. The retractable limiting seat 7 is provided with a foot mold 8 in the middle. An inflatable seat 9 is installed around the foot mold 8. An air bladder 10 is provided inside the inflatable seat 9. A rubber patch 11 is provided on the inner side of the air bladder 10. The rubber patch 11 is attached to the foot mold 8.

[0021] Furthermore, the top of the retractable heat softening mold 5 and the retractable cold pressing mold 6 are equipped with a first telescopic cylinder 12.

[0022] Furthermore, a second telescopic cylinder 13 is installed at the lower part of the telescopic limiting seat 7, which can drive the telescopic limiting seat 7 to move up and down.

[0023] Furthermore, a hot air hood 14 is installed on the front side of the retractable heat softening mold 5.

[0024] Furthermore, the inflation seat 9 is provided with an inflation / deflation port 15 on one side, which is connected to an external air pump.

[0025] Furthermore, an infrared rangefinder 16 is installed on one side of the bottom of the retractable limiting seat 7.

[0026] Example: First, place the shoe upper on the heat softening station 2, with the heel of the shoe upper covering the heel mold 4 and the shoe edge drooping down, and the forefoot of the shoe upper covering the foot mold 8 and the shoe edge drooping down. Next, start the external air pump to inflate the airbag 10 through the inflation / deflation port 15. After the airbag 10 is inflated, the rubber patch 11 on the inner side of the airbag 10 adheres to the center from the left, right, and lower sides. The forefoot of the shoe upper is clamped by the rubber patch 11 and the foot mold 8. Then, according to the size of the shoe upper, first activate the first telescopic cylinder 12 to clamp the heel of the shoe upper. Then, the second telescopic cylinder 13 is activated, which drives the telescopic limit seat 7 to move downwards. The distance is measured by the infrared rangefinder 16. The telescopic limit seat 7 can accurately move to the specific distance for each size. This operation straightens the shoe upper and avoids wrinkles. Finally, the hot air generated by the hot air hood 14 softens the heel of the shoe upper. After softening, the shoe upper is placed in the cold pressing and shaping station 3. The above operation is repeated to cold press and shape the heel of the shoe upper. The softening and cold pressing of the shoe upper are completed in one piece in the equipment body 1.

[0027] 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:

[0028] This invention first integrates a heat softening station and a cold pressing station on the equipment body, allowing for the combined heat softening and cold pressing of the shoe upper. This results in better heel shaping. The integrated design of the heat softening and cold pressing stations also effectively improves processing efficiency and reduces worker waiting time. Next, the heel of the shoe upper is fixed using a retractable heat softening mold and a retractable cold pressing mold. Then, the airbag on the retractable limiting seat at the front of the heat softening and cold pressing stations inflates, causing the rubber patch to contact the foot mold. The upper is clamped to the forefoot area of ​​the shoe, and then straightened by a second telescopic cylinder to prevent wrinkles at the heel, which would affect the heat-softening and cold-pressing effects.
