[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 4 As shown, the utility model provides a rubber shoe upper glueing mechanism, including an operating table 1, a driving shaft 2 is rotatably inserted at the top of the operating table 1, a driving pulley 4 is fixedly sleeved on the outer side of the driving shaft 2, a pin shaft 3 is fixedly installed at the top of the operating table 1, a driven pulley 5 is rotatably sleeved on the outer side of the pin shaft 3, a revolving belt 6 is sleeved on the outer sides of the driving pulley 4 and the driven pulley 5, and the cross-sectional structure of the driving pulley 4 and the driven pulley 5 is as shown in FIG. Figure 2 A plurality of U-shaped rods 7 are fixedly installed on the top of the rotating belt 6, a glue brush 8 is fixedly installed on the outside of the U-shaped rod 7, and a glue-applying platform 9 is arranged on the top of the operating table 1. Figure 2 At this time, the gluing platform 9 is at the highest point, and a return mechanism is provided at the bottom end of the gluing platform 9, which includes a longitudinal rod 11 and a return spring 12.

[0021] The longitudinal rod 11 is slidably and interlacedly connected with the top end of the operating table 1, and the top end of the longitudinal rod 11 is fixedly installed with the bottom end of the gluing platform 9. The return spring 12 is sleeved on the outside of the longitudinal rod 11. The longitudinal rod 11 is used to guide the return spring 12 during longitudinal compression and rebound. The top end of the return spring 12 contacts with the bottom end of the gluing platform 9, and the bottom end of the return spring 12 contacts with the top end of the operating table 1. The return spring 12 is always in a compressed state and has a certain elastic potential energy.

[0022] A motor 10 is fixedly mounted at the bottom of the operating table 1. The motor 10 is electrically connected to an external power source via an external power line. The output shaft of the motor 10 is transmission-connected to the driving shaft 2. The motor 10 is used to provide power to the entire device.

[0023] A plurality of guide rods 13 are fixedly installed at the bottom end of the gluing platform 9, and the plurality of guide rods 13 are slidably and interlacedly connected with the top end of the operating platform 1. An upper limit block 14 is fixedly sleeved in the middle of the guide rod 13. When the gluing platform 9 is at the lowest point, the bottom end of the upper limit block 14 contacts the top end of the operating platform 1, and at this time, the glue brush 8 fits against the upper surface of the shoe.

[0024] The bottom of the guide rod 13 is threadedly sleeved with a lower limit block. When the glue platform 9 is at the highest point, the top of the lower limit block fits with the bottom of the operating table 1, and the glue brush 8 is immersed in the glue in the groove at the top of the glue platform 9.

[0025] The top of the operating table 1 is provided with a plurality of mounting grooves equidistantly arranged in a circular array, and the inner walls of the mounting grooves are fixedly mounted with pin rods 15, and the outer sides of the pin rods 15 are rotatably sleeved with rollers 16, and the outer sides of the rollers 16 are rollingly connected to the bottom ends of the driving pulley 4 and the driven pulley 5. When the driving pulley 4 and the driven pulley 5 rotate, the rollers 16 roll in contact with the bottom ends of the driving pulley 4 and the driven pulley 5, thereby avoiding direct contact and friction between the driving pulley 4 and the driven pulley 5 and the top of the operating table 1.

[0026] The working principle and process of the utility model are as follows: Figure 1 At the beginning of the state, the operator injects a certain amount of glue into the groove at the top of the upper glue table 9. At this time, the glue brush 8 is immersed in the glue, the upper glue table 9 is at the highest point, and the top of the lower limit block is in contact with the bottom of the operating table 1.

[0027] The operator starts the motor 10, and the output shaft of the motor 10 rotates clockwise to drive the driving shaft 2 to rotate together. The driving shaft 2 drives the driving pulley 4 on its outer side to rotate together, so that the revolving belt 6 starts to move and drives the driven pulley 5 to rotate around the pin shaft 3. The revolving belt 6 moves while driving the U-shaped rod 7 at its top to move together. The U-shaped rod 7 drives the glue brush 8 on its outer side to move in the groove at the top of the gluing platform 9, so that the glue brush 8 is covered with glue.

[0028] The operator places the shoes on the convex platform at the top of the gluing platform 9. Under the action of the gravity of the shoes, the gluing platform 9 starts to move downward and drives the guide rod 13 and the longitudinal rod 11 to move downward together until the bottom end of the upper limit block 14 contacts the top of the operating table 1. At this time, the gluing platform 9 is at the lowest point. During the movement of the gluing platform 9, the return spring 12 is compressed. At this time, due to the downward movement of the gluing platform 9, the glue brush 8 gradually begins to contact the upper surface of the shoe. The U-shaped rod 7 moves around the shoe under the movement of the revolving belt 6 and brushes the glue onto the upper surface of the shoe.

[0029] After the glue is applied to the shoe upper, the operator takes off the shoe and pushes the gluing platform 9 upward to the highest point under the elastic action of the return spring 12. The glue brush 8 is gradually immersed in the glue in the groove at the top of the gluing platform 9. By doing this reciprocating motion, a better gluing effect and efficiency can be achieved.
