Automatic shoe tongue looping machine

Abstract

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 the shoemaking industry, which includes a machine head (1), and a pull belt is arranged at the rear right side of the machine head (1) Mechanism (2), the front part of the right side of the machine head (1) is provided with a tape cutting mechanism (3), and the tape cutting mechanism (3) is arranged directly in front of the draw tape mechanism (2), and the needle bar of the machine head (1) is directed in the X direction. The right side of the axis is provided with a double-clamp belt feeding mechanism (4), the sewing area of ​​the machine head (1) is provided with an inner and outer pressing sewing mechanism (5), and the inner and outer pressing sewing mechanism (5) is arranged on the machine head (1) The parts of the left and right side slide rails of the feeding bracket (1A); compared with the prior art, the present invention can avoid the winding problem of the webbing during work, makes the drawing and clamping smoother, ensures the quality requirements of webbing sewing, and simplifies the overall structure. The manufacturing cost has been greatly reduced, and it has the characteristics of high degree of automation, convenient operation, high efficiency and excellent 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
