[0022] The following combines the drawings and embodiments to further describe the specific embodiments of the present utility model. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model and cannot be used to limit the protection scope of the present utility model.

[0023] As Figures 1 - 5As shown in the figure, an automatic sewing device for an arched shoe webbing includes a bottom plate 1 and a plurality of first sewing holes 2 opened on the bottom plate 1 corresponding to the sewing thread. A positioning pressing plate 3 for pressing the shoe upper is rotatably arranged on the bottom plate 1, and an arching device for making the shoe webbing in an arched shape is arranged on the positioning pressing plate 3.

[0024] In order to make the shoe webbing present an arched shape after being placed on the positioning pressing plate 3, the arching device includes: a sewing groove 4 opened on the positioning pressing plate 3 and a plurality of support plates 5 arranged on the positioning plate. A pressing device is also arranged on the positioning pressing plate 3 for pressing the cut piece on the shoe upper.

[0025] In order to facilitate adjusting the degree of arching according to production requirements, an adjusting device for facilitating adjusting the degree of arching is also arranged on the support plate 5. The adjusting device includes: a plurality of adjusting plates 6 arranged on the support plate 5. The adjusting plates 6 can be arranged on the adjusting plates 6 by means of glue or screws, so as to facilitate replacing the adjusting plates 6 or stacking and using the adjusting plates 6.

[0026] In order to facilitate placing the shoe webbing at the position corresponding to the first sewing hole 2 for sewing, a positioning device for facilitating placing the shoe webbing is also arranged on the positioning pressing plate 3. The positioning device includes: a plurality of placing grooves 7 opened on the positioning pressing plate 3 and located on the left and right sides of the sewing groove 4 respectively. The placing grooves 7 are arranged corresponding to the first sewing holes 2.

[0027] In order to shape and position the shoe webbing to keep it in an arched state, the pressing device includes: a pressing plate 8 rotatably arranged on the positioning pressing plate 3, an avoidance groove 9 opened on the pressing plate 8 for avoiding the support plate 5, a plurality of lower pressing plates 10 arranged at the bottom of the pressing plate 8 for pressing down the shoe webbing, and a plurality of second sewing holes 11 opened on the lower pressing plates 10 and the pressing plate 8 corresponding to the first sewing holes 2.

[0028] As Figure 5 shown, in order to facilitate the production and processing of the pressing plate 8, the second sewing holes 11 adjacent to the avoidance groove 9 can be merged with each other.

[0029] In order to prevent the pressing plate 8 and the positioning pressing plate 3 from separating during sewing and causing sewing failure, a fixing device for pressing the pressing plate 8 and thus pressing the positioning pressing plate 3 together is also arranged on the bottom plate 1. The fixing device includes: two horizontal quick clamps (not shown in the figure) respectively arranged on both sides of the bottom plate 1 and an extension plate 12 arranged on the pressing plate 8 and extending towards the horizontal quick clamp.

[0030] In order to improve the convenience of use, a plurality of positioning pins 13 corresponding to the shoe upper are also arranged on the bottom plate 1 for preventing the shoe upper from being placed in the wrong position.

[0031] Working principle: When in use, place the shoe upper at a suitable position on the bottom plate 1 through the positioning pins 13. Then cover the positioning pressing plate 3 on the shoe upper. Place the shoe webbing in the placement groove 7, and then flip the pressing plate 8 to cover it on the positioning pressing plate 3. At this time, due to the height difference between the adjusting plate 6 and the lower pressing plate 10, the shoe webbing will be in an arched shape. At this time, the pressing plate 8 can be fixed by a horizontal quick clamp to complete the shaping and positioning of the shoe webbing, and then sewing can be started.

[0032] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and descriptions only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
