Description

Technical Field

[0001] The utility model relates to the field of shoe material processing equipment, in particular to a multi-station shoe upper sheet pressing mechanism. Background Art

[0002] In recent years, with the advancement of textile technology, the demand for seamless sewing technology has gradually emerged.

[0003] Among these technologies, shaping the upper by vacuum adsorption is a commonly used method. In the current prior art, during processing, the shoe materials (two or more pieces) are adsorbed and bonded by a vacuum adsorption device, and then the shoe materials are heated by a drying device to heat-cure the glue or activate the solid glue, so that the shoe materials are precisely bonded, thereby achieving mutual bonding of the shoe materials.

[0004] For example, Chinese patent CN201610059310.X adopts a vacuum adsorption method and then heat-dries the shoe material by heating the oven bracket. However, in actual findings, the degree of glue adhesion does not meet the predetermined requirements or the integrity of the sheet still has deviations. Although it realizes multi-station processing, the processing efficiency is slow, that is, the heating time is short, but the cooling time is long, so the utilization rate of the machine is low. Utility Model Content

[0005] The main purpose of the utility model is to propose a multi-station upper sheet pressing mechanism, aiming to improve the existing upper sheet pressing mechanism, thereby achieving stable processing of the upper sheet, and the sheet fit and glue fit are stable, and processing at different stations can be achieved through a single structure, effectively saving production costs.

[0006] In order to achieve the above-mentioned purpose, the utility model proposes a multi-station upper sheet pressing mechanism, comprising:

[0007] A frame, wherein at least two pressing devices are provided in the transverse direction of the frame;

[0008] The pressing device comprises a longitudinal movable frame longitudinally arranged on the frame, a bearing seat arranged on the longitudinal movable frame and a pressing seat arranged above the frame, and the frame is provided with a loading position and a processing position;

[0009] The support seat is provided with a plurality of adsorption holes arranged at intervals, and the adsorption holes are connected to a vacuum device. When a sheet is placed on the upper wall of the support seat, the sheet of the support seat is also provided with a detachable film covering member, and the film covering member can cover the sheet and fit the position of the support seat away from the sheet;

[0010] The telescopic device is connected to the pressure seat, and the pressure seat is connected to the temperature control device, and the temperature of the pressure seat can be controlled to a predetermined value. The pressure seat can be switched between a position in contact with the bearing seat and a position away from the bearing seat.

[0011] At least two pressing devices are arranged on the frame and connected through different temperature control devices, thereby realizing different processing steps of the sheet material, effectively reducing the production cost of the equipment;

[0012] In actual processing, the sheets (two or more sheets) are stacked and placed on the bearing seat, and then the film covering the sheets is covered. At this time, the vacuum adsorption device is turned on, so that the film covering generates negative pressure and the sheets are attached to each other, thereby achieving vacuum. At the same time, the bearing seat is moved to the processing position, and the pressure seat is attached to the film covering under the drive of the telescopic device, thereby achieving the processing of the sheets.

[0013] There are two pressing devices, the front end can be a hot pressing device, and the rear end is a cold pressing device, so as to realize the processing and shaping of the sheet. Through the double-sided shaping method, the flatness and fit of the sheet can be improved. BRIEF DESCRIPTION OF THE DRAWINGS
