Automatic shoe tongue looping machine

Abstract

The invention belongs to the technical field of sewing equipment, and particularly relates to an automatic shoe tongue looping machine suitable for sewing process in shoemaking industry. The automaticshoe tongue looping machine comprises a machine head (1), a belt drawing mechanism (2) is arranged on the rear portion of the right side of the machine head (1), a belt cutting mechanism (3) is arranged on the front portion of the right side of the machine head (1) and arranged right in front of the belt drawing mechanism (2), a double-clamp belt receiving and feeding mechanism (4) is arranged onthe right side of X-direction axis of a needle bar of the machine head (1), and inner and outer compression sewing mechanisms (5) are arranged in a sewing area of the machine head (1) and arranged onleft-side and right-side sliding rails of a material feeding support (1A) of the machine head (1). Compared with the prior art, the automatic shoe tongue looping machine has the advantages that winding of weaving belts during working can be avoided to enable clamp drawing to be smoother, so that quality requirements on sewing the weaving belts are ensured, integral structure is simplified, and manufacturing cost is lowered substantially; the automatic shoe tongue looping machine is high in automation level, convenient to operate, high in efficiency and excellent in quality.

Description

[technical field] [0001] The invention belongs to the technical field of sewing equipment, in particular to an automatic shoe tongue loop machine suitable for the sewing process of sports shoes in the shoemaking industry. [Background technique] [0002] The common shoe tongue loop machine sewing process requirements are similar to those of ordinary trousers loops, that is, the formed trouser loops are flat and circular, and one part of the sewing stitches is bright, and the other is dark. Since the final forming length of the shoe tongue loop is relatively small, it is required not to exceed 20mm, so it is more difficult to sew than the trouser loop, and the manual operation speed is slow. [0003] Ten years ago, an automatic shoe loop machine for sewing trouser loops appeared in this field. On this basis, this model was later remade into a shoe tongue loop machine. Its technical characteristics are based on the Japanese heavy machinery company. The tongue loop machine is t...

Problems solved by technology

In addition, because the webbing wraps the clamping rod during the rotation process, and after the belt is in place, the inner pressure plate presses down and retreats to draw the belt. This method of forced clamping makes it easy to draw the webbing crookedly, which makes it difficult for this type of machine Fully ensure the quality requirements of webbing sewing

In the end, the whole mechanism is complicated and the cost is high
