Toe cap and heel cold-hot shaping integrated machine

Abstract

The invention discloses a toe cap and heel cold-hot shaping integrated machine. The machine comprises a machine frame, a toe cap softening device, a heel softening device, a toe cap shaping device, aheel shaping device, a softening connection transmission mechanism and a shaping connection transmission mechanism; the softening connection transmission mechanism and the shaping connection transmission mechanism are mounted on the machine frame side by side; each of the softening connection transmission mechanism and the shaping connection transmission mechanism comprises a servo motor, a frontpositioning seat adjusting mechanism, a front positioning seat, a front screw rod, a front guide rod, a front nut, a front moving seat, a rear positioning seat, a rear screw rod, a rear guide rod, a rear nut, a rear moving seat, an elastic tensioning mechanism and a universal coupling; the softening connection transmission mechanism connects the toe cap softening device and the heel softening device into a whole; and the shaping connection transmission mechanism connects the toe cap shaping device and the heel shaping device into a whole. Toe caps and heels can be tensioned normally, and whenthe size of each shoe is changed, the height of each front last can be adjusted as long as the height of the front positioning seat is adjusted, so that one-time accurate shaping of the shoe uppers ofdifferent sizes of shoes can be realized.

Description

technical field [0001] The invention relates to shoe-making equipment, in particular to an integrated machine for cold and hot shaping of toes and heels. Background technique [0002] Whether the shoe is beautiful and comfortable to wear depends on whether the upper can be shaped according to the pre-designed shape. [0003] The shaping of the rear part of the upper, that is, the heel, is relatively simple. Because the longitudinal depth of the heel is relatively large, it is easy to completely wrap the rear last, as long as it is heated and softened, and the heel is pressed on the rear last for cooling and shaping; while the front of the shoe It is more difficult to shape the upper part, that is, the toe cap. Because the longitudinal depth of the toe cap is small, it is difficult to wrap the front last. Therefore, when cooling and shaping the toe cap, in order to ensure accurate positioning of the wrapping, the front last must move After reaching around the front last and ...

Problems solved by technology

[0004] Due to the complex control of the toe shape, and when the size of the shoe changes, not only the distance between the toe tip and the heel will change, but also the height difference between the toe surface and the lower edge of the heel will also change. , so that the heating and softening of the heel and toe cap of the shoe upper must be carried out separately. In this way, the separate shaping has the defect of inaccurate alignment, which may easily lead to incoordination between the toe cap and the heel

[0005] Many people are trying to design a vamp shaping machine that can carry out shoe heel and toe cap (that is, the entire vamp) at the same time, put the vamp on the front and rear lasts, and then tighten them from the front and back through the translation mechanism. This is easy to think of, but, as mentioned above, when the size of the shoe changes, not only the distance between the tip of the toe and the heel changes, but also the height difference between the surface of the toe and the lower edge of the heel. It will change accordingly. Since the rear last has a large longitudinal depth, the heating and softening of the heel, cooling and shaping only need to simply wrap the rear last. Therefore, the height of the rear last generally does not need to be adjusted, while the height of the front last must be adjusted according to However, if the height position of the front last is adjusted, then all the processing structures corresponding to the front last, such as translation, lowering positioning, pressing down, wrapping and other structures must be adjusted accordingly, which is obviously difficult. It is not scientific, therefore, there is no vamp shaping equipment that can realize one-time shaping
