[0029] The specific implementation of the utility model will be described below in combination with the drawings.

[0030] As shown in Figure 1 , Figure 2 and Figure 3 , the shoe lace pulling auxiliary mechanism of the automatic shoe lace tying machine of the embodiment comprises a back plate 1, the back plate 1 is provided with a lifting seat 5 on the side through a lifting mechanism 2, and a rod mechanism 3 is installed on the left and right sides of the lifting seat 5; further comprising a vertical rod 4 located between the two groups of rod mechanisms 3, and a brush 6 is arranged on the surface of the vertical rod 4 along the length direction.

[0031] In actual use, the middle part of the shoe lace is moved by the rod mechanism 3, and the shoe lace is pulled downward through the downward action of the lifting mechanism 2, so as to play a role in pulling the shoe lace downward, thereby being able to cooperate with the tightening of the shoe lace in each step of tying the shoe lace, and the setting of the brush 6 on the vertical rod 4 effectively prevents the shoe lace from adhering to the rod mechanism 3, so as to facilitate the realization and guarantee that the rod mechanism 3 repeatedly performs the action of pulling the shoe lace with the tying of the shoe lace.

[0032] As shown in Figure 2 and Figure 4 , the structure of a single group of rod mechanisms 3 is as follows: a support 31 is installed on the lifting seat 5, a rotary drive power 32 is installed on the side of the support 31, the output end of the rotary drive power 32 faces upward and is provided with a rod seat 33, and a rod 34 is installed on the rod seat 33.

[0033] In the embodiment, the rod 34 is moved in the horizontal plane through the action of the rotary drive power 32, as shown in Figure 4 , the rod 34 is rotated from A to B, so that the shoe lace can be pulled onto the rod 34 from above the external clamping mechanism 7, and the rod 34 plays a role in pulling the shoe lace.

[0034] The vertical rod 4 is located at the inner side of the back plate 1 towards the pulling rod 34; so that when the pulling rod 34 pulls the shoelace to the inner side from the outside, the setting of the vertical rod 4 and the brush 6 thereon will not affect the action of the pulling rod 34; and after the pulling rod 34 winds the shoelace to the inner side, with the pulling of the shoelace by the pulling rod 34, the shoelace can be effectively prevented from sticking to the pulling rod 34 by the action of the brush 6 on the inner vertical rod 4, so that the shoelace can be smoothly separated from the pulling rod 34, effectively ensuring the repeated pulling action of the pulling rod 34 in cooperation with the shoelace.

[0035] The pulling rod 34 is rotatably installed at the top end of the rod seat 33 through the rotating shaft 35, the rotating shaft 35 is vertically perpendicular to the rod seat 33 and is horizontally arranged, and the pulling rod 34 rotates in the vertical plane with the rotating shaft 35 as the center.

[0036] In this embodiment, when the pulling rod 34 is not acted on by external force, the pulling rod 34 will be lowered relative to the rod seat 33 with the rotating shaft 35 as the center under the action of its own gravity; during the process of pulling the shoelace, the pulling rod 34 will be acted on by the reaction force of the shoelace and will not be lowered under the action of gravity; and after the reaction force of the shoelace disappears, the pulling rod 34 will automatically lower with the rotating shaft 35 as the center.

[0037] One side of the rod seat 33 is provided with a containing groove 331 for accommodating the lowering of the pulling rod 34; so that after the pulling rod 34 is lowered relative to the rod seat 33 under the action of gravity, it will be accommodated in the containing groove 331.

[0038] The pulling rod 34 is divided into a long section and a short section by the rotating shaft 35, the end of the short section is provided with a guide wheel 36, and when the long section is accommodated in the containing groove 331, the guide wheel 36 is located above and outside the rod seat 33.

[0039] In actual use, with the action of the lifting mechanism 2, the pulling rod mechanism 3 is driven to go up, and when the upper end guide wheel 36 of the pulling rod 34 contacts and abuts against the outer top plate, the pulling rod 34 will rotate in the vertical plane with the rotating shaft 35 as the center under the reaction force of the outer top plate, and the long section of the pulling rod 34 accommodated in the containing groove 331 will be raised to the horizontal.

[0040] The rod seat 33 is provided with a rotating stop surface, and when the long section is raised to the horizontal relative to the rod seat 33, the short section abuts against the rotating stop surface, thereby limiting the rotation of the pulling rod 34 in the vertical plane relative to the rod seat 33.

[0041] In Figure 4 In the embodiment shown, the support 31 is provided with a U-shaped groove 311 opening laterally on the side surface, and the U-shaped groove 311 contains a shaft coupling 37; the rotating driving power 32 is installed outside the lower wall surface of the U-shaped groove 311, the rod seat 33 is rotatably installed on the upper wall surface of the U-shaped groove 311, and the shaft coupling 37 powerfully connects the rotating driving power 32 and the rod seat 33; thereby effectively ensuring that the rod seat 33 is driven to rotate by the rotating driving power 32.

[0042] In the embodiment, the rotating driving power 32 can be selected according to actual needs, such as a motor, a micro direct current motor and the like.

[0043] The clamping mechanism 7 is arranged in pairs and is driven by the linear driving power 8 to move up and down.

[0044] In the embodiment, the shoe lace pulling action can be performed in cooperation with the shoe lace threading action of the clamping mechanism 7 through the arrangement of the lever mechanism 3, so as to ensure the threading effect of the shoe lace.

[0045] In the embodiment, the clamping mechanism 7 only needs to repeatedly perform the clamping and threading actions of the shoe lace head in a limited preset stroke, and the up and down actions of the lever mechanism 3 driven by the lifting mechanism 2 are performed to gradually reduce the pulling stroke of the shoe lace in cooperation with the gradual threading of the shoe lace.

[0046] In the embodiment, the linear driving power 8 can be selected from existing conventional powers, such as a pneumatic cylinder and an electric cylinder.

[0047] The lifting mechanism 2 comprises a support plate 21 which is installed on the side surface of the back plate 1 in an up-down interval, a lead screw 23 which is rotatably installed between the support plates 21, and a guide rod 22 which is installed between the support plates 21 on both sides of the lead screw 23.

[0048] In the embodiment, the lead screw 23 is driven to rotate by an external motor, and the lifting seat 5 which is matched with the lead screw 23 by a screw pair is driven to move up and down along the guide rod 22, so as to realize the up and down movement of the lever mechanism 3 on the lifting seat 5.

[0049] The use mode of the utility model is as follows:

[0050] The lever mechanism 3 is driven to move upward by the lifting mechanism 2 until the upper end guide wheel 36 of the lever 34 is in contact with the external top plate, and then the lever 34 is rotated around the rotating shaft 35 in the vertical plane under the reaction force of the external top plate, and the long section of the lever 34 accommodated in the accommodating groove 331 is swung to be horizontal.

[0051] The rotating driving power 32 is actuated to drive the lever 34 to rotate in the horizontal plane, and the lever 34 is rotated to position A shown in FIG. Figure 4 The external clamping mechanism 7 is actuated to clamp the shoe lace head which is threaded into the shoe hole from top to bottom, and the clamping mechanism 7 is driven to move downward by a preset distance by the action of the linear driving power 8, so as to be lower than the height of the lever 34 at this time.

[0052] The rotation driving power 32 in the dialing rod mechanism 3 acts, drives the dialing rod 34 to rotate from A to B in the middle of the shoelace, and makes the middle of the shoelace wrap around the dialing rod 34, and the dialing rod 34 drives the shoelace to the direction of the vertical rod 4. Figure 4

[0053] With the action of the lifting mechanism 2, the dialing rod 34 pulls the shoelace downward, realizes the shoelace pulling action, and the dialing rod 34 overcomes the gravity due to the reaction of the shoelace and keeps the rotation-out state relative to the rod seat 33; then, the lifting mechanism 2 goes up, the reaction of the shoelace to the dialing rod 34 disappears, the dialing rod 34 will swing downward relative to the rod seat 33 under the action of the gravity, and in combination with the action of the brush 6 on the vertical rod 4, the shoelace is completely separated from the dialing rod 34, and the shoelace pulling action is completed.

[0054] The utility model can tighten the shoelace in each step of wearing the shoelace, effectively prevents the shoelace from adhering to the dialing rod mechanism, facilitates the realization and guarantee of the repeated shoelace pulling action of the dialing rod mechanism with the wearing of the shoelace, helps to guarantee the effect of wearing the shoelace, guarantees the smooth wearing of the shoes in the future, and has good practicability.
