Vacuum setting machine for shoemaking

Abstract

The invention discloses a vacuum setting machine for shoemaking. The vacuum setting machine comprises a frame, a shoe basket, a treatment box, a vacuum hood, a conveying device, a power device and a control device. Two ends of the shoe basket are respectively connected onto the conveying device; the conveying device accurately conveys the shoe basket into the treatment box and below the vacuum hood in time sequence under the action of the power device and the control device; a lifting device is connected onto the vacuum hood; a cavity formed between the vacuum hood and a bottom plate is connected with a vacuum pump through a pipeline; supporting plates are respectively mounted at the two bottom ends of the shoe basket; the two sides of the supporting plates are in the shape of knife edges; an upper sealing gasket is arranged at the opening of the vacuum hood; a lower sealing gasket is arranged on the bottom plate. As the upper sealing gasket is arranged at the opening of the vacuum hood, the lower sealing gasket is arranged on the bottom plate, and the supporting plates at the two ends of the shoe basket are in the shape of knife edges, the supporting plates are buckled between the upper sealing gasket and the lower sealing gasket during vacuum pumping, the sealing effect is good, and air leakage can not occur.

Description

[0001] technical field [0002] The invention relates to a shoe-making machine, in particular to a vacuum shoe shaping machine. [0003] Background technique [0004] In the process of shoemaking, after the vamp has been treated with heat or humidity, it needs to be evacuated through a vacuum box to extract the moisture of the vamp and the air between the vamp and the last, so that the vamp is more durable and sticks to the last. Existing vacuum shoe shaping machines include belt conveying type and shoe basket type. The belt conveying type vacuum shaping machine places shoes on the belt, and the shoes on the belt are covered by a vacuum cover to vacuumize. This method has a good sealing effect, but The production efficiency is low; the shoe basket vacuum setting machine puts the shoes in the shoe basket, and the whole shoe basket is covered by the vacuum cover for vacuuming. This method has high production efficiency. The connectors are difficult to seal when vacuuming, an...
