[0024] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0025] The following describes the upper and sole reinforcement and sewing device for labor protection shoes according to an embodiment of the present application with reference to the accompanying drawings.

[0026] like Figures 1-6As shown, the upper and sole reinforcement and sewing device of the labor protection shoes in the embodiment of the present application may include a working box 1, a sewing device 2, a sole limiting plate 3, an upper limiting component 4, a first rotation control component 5 and a second rotation control component 6.

[0027] A mounting plate 10 is provided in the working box 1 , and the sewing device 2 is provided on the working box 1 and is located above one side of the sole limiting plate 3 .

[0028] It should be noted that the suturing device 2 described in this embodiment is a common suturing device 2 on the market.

[0029] The sole limiting plate 3 is arranged on the first rotation control assembly 5 , the sole limiting plate 3 is slidably connected to the working box 1 , and a limiting groove 30 is provided on the sole limiting plate 3 .

[0030] It should be noted that the shape of the limiting groove 30 provided on the sole limiting plate 3 described in this embodiment is the same as the shape of the sole and is slightly larger than the size of the sole, thereby achieving the limitation of the sole.

[0031] The upper limiting assembly 4 is arranged on the working box 1 , and the upper limiting assembly 4 is located above the other side of the sole limiting plate 3 .

[0032] In the embodiment of the present application, the upper limiting assembly 4 is used to limit the position of the upper so that the upper can be pressed tightly against the sole, thereby facilitating the sewing of the upper and the sole by the sewing device 2.

[0033] The first rotation control component 5 is elastically and slidably arranged on the mounting plate 10 , and the first rotation control component 5 is used to control the rotation of the sole limiting plate 3 .

[0034] It can be understood that through the setting of the first rotation control component 5, the sole limiting plate 3 can be driven and controlled, that is, when the suturing device 2 sews the sole and the upper, the first rotation control component 5 controls the sole limiting plate 3 to rotate, so that the sole limiting plate 3 drives the sole and the upper to rotate, thereby enabling the suturing device 2 to sew the sole and the upper at different positions in a full circle, thereby eliminating the need for relevant staff to manually push the upper and the sole for suturing, reducing the labor intensity of relevant staff and improving the operating safety of relevant operators.

[0035] The second rotation control assembly 6 is disposed on the mounting plate 10 , and the second rotation control assembly 6 abuts against the first rotation control assembly 5 , and controls the first rotation control assembly 5 to slide in a specified manner.

[0036] It can be understood that, through the setting of the second rotation control component 6, the second rotation control component 6 can control the sliding of the first rotation control component 5 according to the shape of the sole, and through the rotation control of the sole limiting plate 3 by the first rotation control component 5, the protruding parts and recessed parts of the sole and the upper can always be located below the stitching point of the stitching device 2 during the rotation process, thereby realizing mechanical stitching of the upper and the sole, and no manual operation is required by relevant staff, thereby reducing the labor intensity of relevant staff and improving the operating safety of relevant operators.

[0037] Specifically, during the actual operation, the relevant staff puts the sole into the limiting groove 30 in the sole limiting plate 3. The size of the limiting groove 30 is slightly larger than the size of the sole limiting plate 3, so that the sole limiting plate 3 can be placed in and limit the position of the sole. The relevant staff then places the upper on the sole, and the controller (not shown in the figure) controls the upper limiting component 4 to extend and abut and limit the upper, pressing the upper tightly against the sole and leaving space for stitching. The controller controls the stitching device 2 to sew, and the stitching device 2 sews the upper and the sole.

[0038] During the stitching process, the controller controls the first rotation control component 5 to rotate, and the rotation of the first rotation control component 5 drives the sole limiting plate 3 to rotate, so that the position of the stitching device 2 remains unchanged, and stitching can still be performed on different positions of the sole and the upper.

[0039] At the same time, the controller controls the rotation of the second rotation control component 6, and the rotation of the second rotation control component 6 performs displacement sliding control on the first rotation control component 5, and the displacement sliding control adjusts the protruding part and the recessed part of the sole, so that the irregular shape of the sole and the upper is rotated by the stitching device 2 to perform a circle of stitching, thereby realizing the stitching of the upper and the sole, and no manual operation is required by the relevant staff, thereby reducing the labor intensity of the relevant staff and improving the operating safety of the relevant operators.

[0040] In one embodiment of the present application, Figure 3 As shown, the first rotation control assembly 5 may include a first driving motor 50 , a fixing plate 51 , an abutment rod 52 and an elastic abutment member 53 .

[0041] Among them, the first drive motor 50 is arranged on the fixed plate 51, the output shaft of the first drive motor 50 is connected to the sole limiting plate 3, the fixed plate 51 is slidably set on the mounting plate 10, the abutment rod 52 is set on one side of the fixed plate 51, the abutment rod 52 abuts against one end of the second rotation control component 6, and the elastic abutment member 53 is set on the mounting plate 10, and one end of the elastic abutment member 53 is connected to the fixed plate 51.

[0042] It can be understood that, through the connection between the output shaft of the first drive motor 50 and the sole limiting plate 3, the rotation of the first drive motor 50 can drive the sole limiting plate 3 to rotate, and through the sliding connection between the fixing plate 51 and the mounting plate 10, the second rotation control component 6 can drive the first drive motor 50 and the sole limiting plate 3 to slide in the slide groove (not shown in the figure) opened on the working box 1, thereby realizing mechanical suturing of the upper and the sole.

[0043] It should be noted that the abutment rod 52 described in this example is provided with a ball bearing. The provision of the ball bearing reduces the friction between the abutment rod 52 and the abutment mold 62 in the second rotation control assembly 6, thereby increasing the service life of the abutment rod 52.

[0044] It can be understood that by setting the elastic abutment 53, it can be ensured that the lower rod and the abutment mold 62 in the second rotation control assembly 6 are in a state of continuous abutment, thereby ensuring that the abutment mold 62 controls the position of the abutment rod 52 and the fixed plate 51, and ensuring the mechanical stitching of the upper and the sole.

[0045] In one embodiment of the present application, Figure 3 As shown, the second rotation control assembly 6 may include a second driving motor 60 , a connecting cylinder 61 and an abutting mold 62 .

[0046] Among them, the second drive motor 60 is arranged on the mounting plate 10, the output shaft of the second drive motor 60 is connected to the connecting tube 61, one end of the connecting tube 61 is connected to the abutment mold 62, the abutment mold 62 is rotatably abutted with the abutment rod 52, and the abutment mold 62 is rotatably connected to the mounting plate 10.

[0047] It should be noted that the abutment mold 62 described in this embodiment has the same shape and size as the sole, and when the abutment mold 62 rotates and abuts the abutment rod 52, the displacement of the fixed plate 51, the first drive motor 50 and the sole limiting plate 3 can be controlled according to the actual shape of the sole, thereby ensuring accurate mechanical stitching of the sole and the upper in the sole limiting plate 3.

[0048] It should be noted that the first drive motor 50 and the second drive motor 60 described in this embodiment are respectively provided with a synchronization controller, so as to ensure that the first drive motor 50 and the second drive motor 60 rotate at the same time, thereby further ensuring accurate mechanical stitching of the sole and the upper in the sole limiting plate 3.

[0049] In one embodiment of the present application, Figure 3 and Figure 5 As shown, the elastic abutment member 53 may include a connecting tube 530 , a spring 531 and a fixing tube 532 .

[0050] Among them, the connecting tube 530 is connected to the fixed plate 51, one end of the connecting tube 530 extends into the fixed tube 532 and abuts against the fixed tube 532, the spring 531 is arranged in the fixed tube 532, one end of the spring 531 is connected to the fixed tube 532, and the other end of the spring 531 is connected to the connecting tube 530, and the fixed tube 532 is arranged on the mounting plate 10.

[0051] It can be understood that through the setting of the spring 531, the movement state of the connecting tube 530 and the fixed plate 51 can be controlled in real time, so that the abutment rod 52 on the fixed plate 51 continuously abuts against the abutment mold 62, ensuring that the abutment mold 62 controls the movement of the sole limit plate 3.

[0052] In one embodiment of the present application, Figure 2 As shown, the shoe upper limiting assembly 4 may include a support plate 40 , an electric telescopic rod 41 and a shoe upper limiting ring 42 .

[0053] Among them, the support plate 40 is set on the working box 1, the electric telescopic rod 41 is rotatably set on the support plate 40, the upper limiting ring 42 is located above the sole limiting plate 3, and the upper limiting ring 42 is connected to the extension shaft of the electric telescopic rod 41.

[0054] It is understandable that, through the rotational connection between the electric telescopic rod 41 and the support plate 40, when the sole limiting plate 3 rotates, the electric telescopic rod 41 can follow the rotation of the sole limiting plate 3, thereby ensuring the tight and limited state of the upper and the sole.

[0055] In one embodiment of the present application, Figure 2 As shown, the upper limiting assembly 4 may further include an upper supporting mold 43 , which is disposed above the sole limiting plate 3 , and the bottom surface area of ​​the upper supporting mold 43 is smaller than the area of ​​the limiting groove 30 .

[0056] It is understandable that the provision of the upper support mold 43 can provide auxiliary support to the upper, thereby preventing the upper from collapsing and affecting the suturing efficiency.

[0057] In one embodiment of the present application, Figure 1 As shown, the suturing device 2 may include a drive mechanism 20 and a suturing needle 21 .

[0058] The driving mechanism 20 is provided on the working box 1 , and the suture needle 21 is provided at one end of the driving mechanism 20 .

[0059] It should be noted that the driving mechanism 20 described in this embodiment is the driving mechanism 20 of the common suturing machine on the market, which is not depicted in detail in the figure, and the driving mechanism 20 and the suturing needle 21 are existing technologies, and the specific components and their connection methods are not described in detail here.

[0060] Specifically, during the actual operation, the relevant staff puts the sole into the limiting groove 30 in the sole limiting plate 3. The size of the limiting groove 30 is slightly larger than the size of the sole limiting plate 3, so that the sole limiting plate 3 can be placed in and limit the position of the sole. The relevant staff then puts the upper on the upper support mold 43 and places it on the sole. The controller (not shown in the figure) controls the electric telescopic rod 41 to extend. The extension of the electric telescopic rod 41 drives the upper limiting ring 42 to move downward, and abuts and limits the upper, pressing the upper tightly against the sole, and leaving space for suturing. The controller controls the driving mechanism 20 and the suture needle 21 to sew the upper and the sole.

[0061] During the stitching process, the controller controls the first drive motor 50 to rotate, and the first drive motor 50 drives the sole limiting plate 3 to rotate, and drives the sole and the upper to rotate. At this time, the electric telescopic rod 41 and the upper limiting ring 42 rotate with the sole limiting plate 3, so that the position of the stitching device 2 remains unchanged, and stitching can still be performed on different positions of the sole and the upper.

[0062] At the same time, the controller controls the second drive motor 60 to rotate, and the rotation of the second drive motor 60 drives the abutment mold 62 to rotate. When the abutment mold 62 rotates, it abuts against the abutment rod 52, and controls the position of the fixed plate 51 according to the protruding parts and recessed parts on the abutment mold 62, and when the elastic abutment member 53 elastically abuts the fixed plate 51, the abutment rod 52 is continuously abutted against the abutment mold 62, thereby realizing the real-time displacement sliding control of the abutment mold 62 on the fixed plate 51, the first drive motor 50, the sole limiting plate 3, the sole and the upper, and adjusting the protruding parts and recessed parts of the sole of the displacement sliding control in real time, and according to the rotation control of the sole limiting plate 3 by the first drive motor 50, the irregular shape of the sole and the upper is rotated and stitched for one week by the stitched device 2, thereby realizing the stitching of the upper and the sole, and no manual operation is required by the relevant staff, thereby reducing the labor intensity of the relevant staff and improving the operating safety of the relevant operators.

[0063] In summary, the labor protection shoe upper and sole reinforcement and suturing device of the embodiment of the present application does not require relevant staff to manually limit the upper and sole, and does not require relevant operators to manually push the upper and sole to sew, thereby reducing the labor intensity of relevant staff and ensuring the operational safety of relevant staff.
