DETAILED DESCRIPTION

[0023] The utility model is further described in detail below:

[0024] like Figures 1 to 5 As shown, the utility model provides a shoe hemming device, comprising a fixing bracket 1, a fixing rod 2 and a connecting plate 3, a lifting component 4 is fixedly installed on the inner side of the connecting plate 3, and an auxiliary component 5 is fixedly installed on the bottom of the lifting component 4;

[0025] The auxiliary component 5 includes a mounting plate 51, the bottom of which is fixedly connected to a docking sleeve 52, an outer sleeve 53 is movably mounted on the outside of the docking sleeve 52, an inner connecting rod 54 is movably connected to the inside of the outer connecting rod 53, a movable rod 55 is movably hinged on the outside of the inner connecting rod 54, a support spring 56 is movably connected to the inner connecting rod 54 and the movable rod 55, and a pressure plate 57 is movably mounted on the bottom of the movable rod 55.

[0026] The inner connecting rod 54 is movably connected to the inner part of the outer rod 53. The length of the inner connecting rod 54 inside the outer rod 53 can be adjusted. At the same time, the outer rod 53 is rotatably connected to the outside of the docking sleeve 52. The outer rod 53 can be rotated along the docking sleeve 52 to adjust the position of the pressure plate 57. The bottom of the pressure plate 57 contacts the shoe upper. When the movable rod 55 rotates outward along the inner side of the inner connecting rod 54, the support spring 56 is squeezed. The movable rod 55 is forced to rotate outward to expand the shoe upper, so that the flying woven shoe uppers of different sizes can be expanded and used.

[0027] like Figure 2As shown, the lifting assembly 4 includes a mounting frame 41. Inside the mounting frame 41, a lifting screw rod 42 is rotatably mounted. At the top of the mounting frame 41, a motor 43 connected to the lifting screw rod 42 is fixedly mounted. Outside the lifting screw rod 42, a slider 44 located inside the mounting frame 41 is threadedly connected. At the bottom of the slider 44, a detection assembly 45 is fixedly connected.

[0028] By controlling the motor 43 to drive the lifting screw rod 42 to rotate, since the slider 44 is threadedly connected to the outside of the lifting screw rod 42, as the lifting screw rod 42 rotates, the slider 44 drives the auxiliary assembly 5 at the bottom of the detection assembly 45 to lift, so that the auxiliary assembly 5 contacts the shoe upper for auxiliary use.

[0029] As Figure 3 shown, the detection assembly 45 includes a connecting rod 451. At the bottom of the connecting rod 451, a clamping groove 452 is formed. Inside the clamping groove 452, a clamping ring 453 is movably clamped. Inside the clamping groove 452, a pressure detector 454 located inside the clamping ring 453 is fixedly mounted.

[0030] After the auxiliary assembly 5 contacts the shoe upper, it pushes the clamping ring 453 to slide upward along the inside of the clamping groove 452. By the inside of the clamping ring 453 abutting against the pressure detector 454, the pressure detector 454 can detect the magnitude of the downward pressure, and it can be monitored to avoid the shoe upper of the flyknit being damaged due to excessive downward pressure.

[0031] As Figure 5 shown, the movable rod 55 is inclined outward. At the bottom of the pressing plate 57, a rubber protrusion is adhesively bonded.

[0032] By the movable rod 55 being inclined outward, with the rubber protrusion at its bottom, the friction force is increased when contacting the shoe upper, and the shoe upper is pushed outward to facilitate the edge wrapping operation.

[0033] As Figure 4 shown, a damping ring is provided between the outer sleeve rod 53 and the docking sleeve 52. The outer sleeve rod 53 is arranged at the four corners of the bottom of the mounting plate 51.

[0034] By sleeving and installing a damping ring between the outer sleeve rod 53 and the docking sleeve 52, the outer sleeve rod 53 has resistance when rotating along the docking sleeve 52. By installing the outer sleeve rod 53 at the four corners of the bottom of the mounting plate 51, adjustments can be made separately, and after adjustment, it can be used in a stable state.

[0035] As Figure 5 shown, at the top of the pressing plate 57, a ball head 510 is fixedly connected. The ball head 510 is movably clamped inside the movable rod 55.

[0036] By arranging the ball head 510 between the pressing plate 57 and the movable rod 55, the ball head 510 moves inside the movable rod 55 to ensure that the pressing plate 57 can stably adhere to the shoe upper when the movable rod 55 rotates, ensuring the contact area.

[0037] like Figure 4 As shown, a fixed bottom plate 58 is movably mounted on the bottom of the mounting plate 51 , and a fixing bolt 59 located inside the mounting plate 51 is threadedly mounted on the bottom of the fixed bottom plate 58 .

[0038] The fixing bottom plate 58 is installed and fixed on the bottom of the mounting plate 51 in cooperation with the fixing bolts 59, so as to provide support for the outer sleeve rod 53 from the bottom to ensure the connection stability.

[0039] like Figure 1 As shown, the fixing rod 2 is rotatably connected to the top of the fixing bracket 1 , and the connecting plate 3 is fixedly connected to the top of the fixing rod 2 .

[0040] The working principle of the shoe hemming device will be described in detail below.

[0041] like Figures 1 to 5 As shown, the lifting screw rod 42 is driven to rotate by controlling the motor 43. Since the slider 44 is threadedly connected to the outside of the lifting screw rod 42, the slider 44 drives the auxiliary component 5 at the bottom of the detection component 45 to move downward as the lifting screw rod 42 rotates, so that the bottom of the pressing plate 57 arranged at the four corners of the bottom of the mounting plate 51 contacts the vamp. Since the top of the pressing plate 57 is connected to the movable rod 55 through the ball head 510, the ball head 510 is located in the movable rod 55 to ensure the stable fit between the pressing plate 57 and the vamp, so that the pressing plate 57 is more closely connected to the vamp. The surface of the flying woven vamp is relatively rough. The rubber protrusion at the bottom of the pressure plate 57 increases friction, and the support spring 56 is squeezed when the movable rod 55 rotates outward along the inner side of the inner connecting rod 54. The movable rod 55 is forced to rotate outward to open the upper, which is convenient for edging the upper. The inner connecting rod 54 is movably connected to the inner part of the outer rod 53. The length of the inner connecting rod 54 in the outer rod 53 can be adjusted. At the same time, the outer rod 53 is rotatably connected to the outside of the docking sleeve 52. The outer rod 53 can be rotated along the docking sleeve 52 to adjust the position of the pressure plate 57 to adapt to different sizes of flying woven uppers for opening and use.

[0042] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
