Description

Technical Field

[0001] The utility model relates to the field of shoe upper production design, in particular to an adjustable edge folding device used for shoe upper production. Background Art

[0002] During the production process of the shoe upper, the joints of the shoe upper can be reinforced by folding the shoe upper. Usually, a shoe hemming device is used to assist the staff in folding the shoe upper. During use, the existing shoe upper production hemming device needs to guide the shoe upper through a U-shaped plate to facilitate the subsequent folding of the shoe upper and fabric. However, the degree of folding the shoe upper by the U-shaped plate is limited, and the staff needs to manually use additional devices to fold the shoe upper more thoroughly, which reduces the work efficiency to a certain extent. Utility Model Content

[0003] The purpose of the utility model is to provide an adjustable folding device for the production of shoe uppers in order to solve the above-mentioned problems. Through the guide plate and the inclined block, the shoe uppers can be guided and folded conveniently, thereby improving the work efficiency. At the same time, the gas is moved through the air cylinder and the air pipe, and the shoe upper is reset in cooperation with the second spring to achieve repeated extrusion.

[0004] The utility model achieves the above-mentioned purpose through the following technical scheme: an adjustable folding device for shoe upper production, including a main body, a first extrusion structure is arranged inside the main body, a second extrusion structure is arranged inside the main body, a limiting structure is arranged on one side of the interior of the main body, the main body includes a bottom plate and an inclined block, a guide panel is fixedly arranged on the top side of the bottom plate, and the guide panel is fixedly arranged on the rear side of the inclined block.

[0005] The second extrusion structure includes an air rod, an air cylinder and a second support roller. A support rod is fixedly arranged inside the air cylinder near the lower end, a piston is fixedly arranged inside the support rod, a second spring is fixedly connected between the piston and the air cylinder, the second support roller is fixedly arranged at the lower ends of the air rod and the support rod, and an air pipe is fixedly connected between the air cylinder and the air rod.

[0006] Furthermore, the gas rod is fixedly arranged at the lower end inside the inclined block, and the gas cylinder is fixedly arranged at the lower end inside the inclined block.

[0007] Furthermore, the limiting structure includes a screw rod and a support plate, a sliding groove is provided inside the inclined block, and the screw rod is rotatably arranged inside the inclined block.

[0008] Furthermore, a connecting rod is provided at the lower end of the support plate, the connecting rod is slidably arranged inside the slide groove, and the screw rod is threadedly sleeved inside the support plate.

[0009] Furthermore, a limit plate is fixedly provided on the lower end of the connecting rod.

[0010] Furthermore, the first extrusion structure includes a telescopic rod and a first supporting roller, the interior of the telescopic rod is fixedly connected with a first spring, and the first supporting roller is fixedly arranged at the lower end of the telescopic rod.

[0011] Furthermore, a connecting roller is rotatably provided on one side where the inclined block and the bottom plate are close to each other.

[0012] Furthermore, the piston is slidably arranged inside the gas cylinder.

[0013] With the above structure, when the device is used, the upper and the fabric are placed on the base plate, and then the upper is bent by the guide plate, and then the upper is folded by the inclined block, and then the upper is squeezed by the first connecting roller and the second connecting roller. One of the second supporting rollers is pushed by the upper to drive the piston on the supporting rod to squeeze upward, and the piston pushes the gas inside the air cylinder into the air rod through the air pipe, thereby pushing another second supporting rod to squeeze the upper through the air rod. After squeezing, the piston is pushed to reset by the second spring, and then the upper continues to move. By rotating the screw rod, the position of the limit block is controlled to limit the folded upper, and finally, the fabric is moved through the connecting roller.

[0014] In summary, the beneficial effect of the utility model is that when the device is used, the guide panel and the inclined block are used to facilitate the guidance and folding of the shoe upper, thereby improving work efficiency. At the same time, when the shoe upper moves on the inclined block, one of the second support rollers squeezes the shoe upper through the second spring. When the elasticity of the shoe upper is relatively large, one of the second support rollers is pushed by the shoe upper to drive the piston on the support rod to squeeze upward, and the piston pushes the gas inside the air cylinder into the air rod, thereby pushing another second support rod to squeeze the shoe upper through the air rod. When the other extrusion is completed, the shoe upper is reset by the second spring to achieve repeated extrusion, thereby improving the extrusion effect to a certain extent.
