A shoe front lining/back cover processing machine and its processing technology

Abstract

The invention discloses a shoe toe box / heel cap processing machine. The shoe toe box / heel cap processing machine comprises a machine table. The machine table comprises a feeding system, a conveying system, a hot-press forming system, a cooling system and a demolding device. The hot-press forming system comprises at least two hot-press forming molds. Each hot-press forming mold comprises a movable mold body, a fixed mold body and a heating device, wherein a hard metal plate is arranged on the movable mold body, a soft cushion plate correspondingly matched with the hard metal plate is arranged on the fixed mold body, and the heating device is used for heating the hard metal plate. The hot-press forming molds are sequentially arranged. The position of the movable old body of each mold is opposite to the position of the fixed mold body of the corresponding adjacent mold, and the hard metal plates of the molds can exert pressure on the two sides of a shoe toe box / heel cap in a staggered mode. The cooling system comprises a cooling plate used for cooling the shoe toe box / heel cap. The shoe toe box / heel cap processing machine is high in processing efficiency, high in speed, capable of lowering the energy consumption, saving labor, conducting edge chamfering on both the two sides of the edge of the shoe toe box / heel cap and completely conforming to the use technological requirements of shoe factories for the toe box / heel cap, and quite good in cooling effect.

Description

technical field [0001] The invention relates to the technical field of shoe manufacturing equipment, in particular to a shoe front lining / back cover processing machine and a processing technology thereof. Background technique [0002] In the process of shoe manufacturing, in order to increase the strength and hardness of the shoe and maintain the shape of the shoe, it is often necessary to place an inner lining between the inner surface and the inner lining of the shoe. This inner lining mainly includes the front lining and the back cover of the shoe. At present, low-temperature hot-melt adhesive shoe front lining and back cover have become the first choice products in the shoe industry. [0003] During the processing of the shoe front lining / back cover, the shoe front lining / back cover is cut according to a predetermined shape. After cutting, the edge thickness of the shoe front lining / back cover is consistent with the thickness of the middle part. If this If the shoe fron...

Problems solved by technology

[0005] However, the above-mentioned patent 201420279607.3 also has the following defects: First, because the shoe front lining and back cover processing machine is only provided with a set of thermoforming molds, the upper mold is provided with a metal plate, and the lower mold is provided with a soft backing plate. During the press molding process, the side of the shoe front lining / back cover corresponding to the soft backing plate will gradually become thinner, but the side of the shoe front lining / back cover corresponding to the metal plate is in the shape of a flat plate (refer to the patent 201420279607.3 figure 2 ), it is impossible to chamfer both sides of the front lining / back cover edge of the shoe, thus affecting the final shoe appearance, stitching quality and stitching efficiency; second, because the shoe front lining and back cover processing machine uses cooling wheels The group cools the front lining and the back cover of the shoe. Therefore, during the cooling process, the cooling wheel group and the front lining / back cover of the shoe are in a line contact cooling mode. The contact area is small and the cooling efficiency is poor, which affects the front lining of the shoe. The processing quality of the rear sleeve also greatly affects the production efficiency
