Free trajectory gluing device of toe lasting machine

Abstract

The invention discloses a free trajectory gluing device of a toe lasting machine. The free trajectory gluing device comprises two glue nozzles, X-axis and Y-axis servo motors, two groups of X-axis and Y-axis oscillating rods, X-axis and Y-axis rotating shafts, ball screws and ball sliding nuts, wherein the two servo motors are arranged in each of X-axis and Y-axis directions; the ball sliding nut sleeves the ball screw on the head part of each axial servo motor; each ball sliding nut is connected to one end of each axial oscillating rod, and the other end of each axial oscillating rod is connected to each axial rotating shaft; the two groups of X-axis and Y-axis oscillating rods are aggregated at the Y-axis rotating shaft and control the movement direction of the glue nozzles. According to the free trajectory gluing device, the glue nozzles are driven and controlled by two servo motors in each of the X-axis direction and the Y-axis direction, can move back and forth, left and right in a synchronized asymmetric manner, and can move independently, so that the problems of glue leakage and failed gluing due to the curve radians on the left and right sides of a shoe upper are asymmetric are solved.

Description

technical field [0001] The invention relates to the technical field of shoe upper gluing, in particular to a free track gluing device for a upper of a shoe. Background technique [0002] At present, in the shoe leather processing and manufacturing industry, almost all gluing processes are done by hand. my country's footwear has occupied a very important position in the international similar product market, but the overall grade of the product is low, and the quality of the front upper glue is not high is one of the key factors. Most of the automatic front upper machines used in China adopt the way of fixed shoe mold spraying glue for bonding. The shoe shape process is complicated, and because the mold cannot be reused, which affects the innovation of the shoe shape, it is difficult to find employees for the gluing job in shoe factories. In order to reduce the labor cost of shoemaking and improve work safety, the application of mechanical gluing devices has broad prospects. ...

Most of the automatic front upper machines used in China adopt the way of fixed shoe mold spraying glue for bonding. The shoe shape process is complicated, and because the mold cannot be reused, which affects the innovation of the shoe shape, it is difficult to find employees for the gluing job in shoe factories. In order to reduce the labor cost of shoemaking and improve work safety, the application of mechanical gluing devices has broad prospects.

[0003] The first problem to be solved by mechanical gluing is to ensure the quality of gluing. Since the shape of the shoe is relatively complicated, the shape of the gluing surface is irregular, and the size of each shoe is different, so the quality of gluing is not easy to guarantee.

At present, the two glue nozzles of the traditional gluing device can only produce synchronous left and right and forward and backward movements, which do not have the function of independent movement, but the curves on the left and right sides of the upper are not completely equal. When gluing the shoes, there will be problems of unilateral glue leakage or failure to fit
