Description

Technical Field

[0001] The utility model belongs to the technical field of shoemaking equipment, in particular to a shaping device adjusted by a cylinder. Background Art

[0002] Whether a shoe is beautiful and comfortable to wear depends crucially on whether the upper can be shaped according to the pre-designed shape.

[0003] The shaping process for the rear of the upper (the heel) is relatively simple, primarily because the heel has a greater depth, allowing the material to be easily wrapped around the back last. The material is softened by heating, then pressed onto the back last, and then cooled to complete the shaping process.

[0004] In contrast, shaping the vamp (toe cap) is more complex. Due to the shallow longitudinal depth of the toe cap, it is not easy to wrap it directly around the fore last. Therefore, when cooling and shaping the toe cap, it is necessary to first move the fore last mold around the fore last and accurately position it, and then press it down to ensure that the toe cap can be accurately wrapped around the fore last. This toe cap shaping process is not only difficult to control, but also when the size of the shoe changes, in addition to the distance between the toe tip and the heel will be adjusted, the height difference from the toe surface to the bottom of the heel will also change accordingly. These factors require that the heating and softening processes of the heel and toe cap must be carried out separately. Such separate processing methods may cause inaccurate alignment problems, thereby affecting the coordination between the toe cap and the heel.

[0005] In order to solve the above problems, the Chinese patent application number CN110384310A discloses a toe and heel hot and cold shaping integrated machine, which connects the toe softening device and the heel softening device into one through a softening connection transmission mechanism, and connects the toe shaping device and the heel shaping device into one through a shaping connection transmission mechanism. In addition to being able to normally adjust the distance between the toe softening device and the heel softening device, and between the toe shaping device and the heel shaping device, when the shoe size changes, the height position of the front positioning seat is changed, and the distance between the toe softening device and the heel softening device can still be adjusted through the universal joint. The distance between the toe molding device and the heel molding device, and the position and connection relationship of the toe softening device and the toe molding device installed on the front movable seat remain unchanged. All related processing structures of the front last, such as translation, descending positioning, pressing down, wrapping, etc., are all installed on the front movable seat. When the size of the shoe changes, the height position of the front last can be adjusted by adjusting the height position of the front positioning seat, and no other structure needs to be adjusted, thereby realizing the one-time accurate molding of the uppers of shoes of different sizes, making the one-time molding upper molding equipment achievable and universal and practical.

[0006] However, since the softening connection transmission mechanism adopts a servo motor + screw drive method to connect the toe softening device and the heel softening device into one, the shaping connection transmission mechanism also adopts a servo motor + screw drive method to connect the toe shaping device and the heel shaping device into one, there are the following problems: the servo motor + screw drive method has a relatively complex structure and a high equipment cost. Since they are linked, the toe softening device and the heel softening device can only move back to back or towards each other together, and the toe shaping device and the heel shaping device can only move back to back or towards each other together, and cannot move independently. Their independence and versatility are not strong enough. Utility Model Content

[0048] The working principle of this utility model is:

[0049] During operation, first, the height position of the first front slider 4 is adjusted by the first height adjustment mechanism according to the size of the shoe, thereby adjusting the height position of the toe molding component 2, and the height position of the toe softening component 10 is adjusted by the second height adjustment mechanism. The distance between the toe softening component 10 and the heel softening component 11 is preset by the second front driving mechanism and the second rear driving mechanism. The distance between the toe molding component 2 and the heel molding component 3 is preset by the first front driving mechanism and the first rear driving mechanism. Then, the toe and the heel of the upper are clamped on the toe softening component 10 and the heel softening component 11 respectively, and the toe softening component 10 and the heel softening component 11 heat and soften the toe and the heel; the softened toe and the heel of the upper are clamped on the toe molding component 2 and the heel molding component 3 respectively, and the toe molding component 2 and the heel molding component 3 cool and mold the toe and the heel.

[0050] When the distance between the toe softening component 10 and the heel softening component 11 needs to be increased in response to different shoe sizes, the second front driving mechanism and the second rear driving mechanism drive the second front slider 12 and the second rear slider 15 to move in opposite directions, driving the toe softening component 10 and the heel softening component 11 to move in opposite directions, and the second height adjustment mechanism adjusts the height position of the second front slider 12 to adjust the height position of the toe softening component 10; when the distance between the toe softening component 10 and the heel softening component 11 needs to be reduced in response to different shoe sizes, the second front driving mechanism and the second rear driving mechanism drive the second front slider 12 and the second rear slider 15 to move in opposite directions respectively, driving the toe softening component 10 and the heel softening component 11 to move in opposite directions, and the second height adjustment mechanism adjusts the height position of the second front slider 12 to adjust the height position of the toe softening component 10.

[0051] Similarly, when facing different shoe sizes and needing to increase the distance between the toe molding component 2 and the heel molding component 3, the first front driving mechanism and the first rear driving mechanism drive the first front slider 4 and the first rear slider 7 to move in opposite directions, driving the toe molding component 2 and the heel molding component 3 to move in opposite directions, and the first height adjusting mechanism adjusts the height position of the first front slider 4 to adjust the height position of the toe molding component 2; when facing different shoe sizes and needing to reduce the distance between the toe molding component 2 and the heel molding component 3, the first front driving mechanism and the first rear driving mechanism drive the first front slider 4 and the first rear slider 7 to move toward each other, driving the toe molding component 2 and the heel molding component 3 to move toward each other, and the first height adjusting mechanism adjusts the height position of the first front slider 4 to adjust the height position of the toe molding component 2.
