Automatic vamp pressure maintaining device

Abstract

The invention discloses an automatic vamp pressure maintaining device which comprises a bottom plate, a PLC control device, a vamp limiting unit installed on the bottom plate and a gland fastening unit, wherein the vamp limiting unit and the bottom plate are installed in parallel and used for limiting a vamp, a flip cover pressure maintaining unit comprises a flip cover control device, a gland and an air bag, the air bag is communicated with an air source, the lower end of the gland is rotatably mounted on a bearing plate and is driven by the flip cover control device to control the rotation condition of the gland, the flip cover control device is mounted on the bottom plate, the gland rotates downwards to be buckled on the upper surfaces of the vamp limiting unit and the gland fastening unit, the air source inflates the air bag to enable the air bag to expand to wrap the vamp so as to form a closed pressure maintaining interval, the gland fastening unit can press or be separated from the upper surface of the gland after rotating by a certain angle, and the PLC control device is used for controlling the flip cover pressure maintaining unit and the gland fastening unit to work. The device has the advantages of automatic vamp pressure maintaining, accurate working process control, high vamp pressure maintaining efficiency, high vamp pressure maintaining quality and the like.

Description

【Technical field】 [0001] The invention belongs to the technical field of footwear production equipment, and in particular relates to an automatic vamp pressure maintaining device. 【Background technique】 [0002] After the shoe is pasted with glue, it is necessary to carry out the process of maintaining pressure on the upper. The traditional way of maintaining pressure on the upper is to maintain pressure manually. There are problems such as low efficiency, high labor intensity, and staff mistakes during operation. If the pressure holding time is too long during the inflation and pressure holding process, the airbag will explode. 【Content of invention】 [0003] The purpose of the present invention is to solve the problems in the background technology, and propose an automatic vamp pressure maintaining device, which can realize automatic vamp pressure maintenance, precise workflow control, and high efficiency and quality of vamp pressure maintenance. [0004] In order to ac...
