Description

Technical Field

[0001] This application relates to the field of shoe sole production technology, specifically to a glue coating device for shoe sole production. Background Technology

[0002] In the sole production process, the glue application process is a crucial step. The quality of the glue application not only affects the strength of the bond between the sole and the upper, but also has a significant impact on the shoe's waterproof and sealing properties. High-quality glue application ensures that the sole and upper can be tightly bonded in various usage environments, making it less prone to separation, thereby improving the overall quality and durability of the shoe.

[0003] In the glue coating process of shoe sole production, traditional glue coating equipment has obvious limitations. Its mechanical structure is often designed with a fixed shape and lacks flexible steering design. This makes it difficult for the equipment to make precise adjustments according to the complex and ever-changing glue coating path when facing shoe soles of different shapes and types, thus failing to achieve high-quality and highly adaptable glue coating operations. Utility Model Content

[0004] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and to propose a glue coating device for shoe sole production, so as to solve the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides a gluing device for shoe sole production, including a device platform. Four sets of rotary joints are rotatably connected to the device platform, and the output ends of each of the four sets of rotary joints are fixedly connected to a vertical pipe. A gluing mechanism is installed at the top of each of the four sets of vertical pipes. A glue cylinder is installed at the bottom of the device platform, and four sets of infusion pumps are installed on the glue cylinder. The output ends of each of the four sets of infusion pumps are fixedly connected to infusion pipes, and the top ends of the four sets of infusion pipes are rotatably connected to the input ends of the four sets of rotary joints. A synchronous steering mechanism is installed on the device platform.

[0006] Preferably, the adhesive application mechanism includes a liquid storage tank fixedly connected to the top of the riser, and the liquid storage tank is provided with a liquid outlet. The adhesive application mechanism can use the rotation of the adhesive roller on the roller shaft to apply the adhesive on the relevant position of the shoe sole (the adhesive roller is made of polyurethane material).

[0007] Preferably, a roller is fixedly inserted through the inner side of the liquid storage tank, and an adhesive roller is rotatably connected to the outer surface of the roller.

[0008] Preferably, the synchronous steering mechanism includes a motor fixedly installed at the bottom of the device platform. The output end of the motor is fixedly connected to a pinion gear. The synchronous steering mechanism can simultaneously adjust the coating direction of four sets of adhesive rollers so as to simultaneously apply adhesive to four different types of shoe soles (i.e., different adhesive application paths).

[0009] Preferably, a rotating shaft is rotatably connected to the top of the device platform, a large gear is fixedly sleeved on the outer surface of the rotating shaft, and the outer surface of the large gear meshes with the outer surface of the small gear. A four-cornered star-shaped plate is fixedly connected to the top of the rotating shaft.

[0010] Preferably, the four-corner star-shaped plate has guide strip holes, and an L-shaped guide rod is slidably connected in the guide strip holes, with the end of the L-shaped guide rod away from the four-corner star-shaped plate being fixedly connected to the outer surface of the rotary joint.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. The adhesive coating device for shoe sole production uses a motor-driven gear transmission system (small gear and large gear) in a synchronous steering mechanism to drive the four-corner star-shaped plate to rotate. The oblique trajectory of the guide strip hole converts the rotational motion into the synchronous deflection of four sets of rotary joints through the L-shaped guide rod, so that the adhesive coating roller changes the adhesive coating direction, thereby enabling precise matching of the complex contours and variable paths of different shoe soles.

[0012] 2. The adhesive coating device for shoe sole production uses a fluid dynamics-optimized liquid tank outlet and a coating roller made of polyurethane material to work together to ensure that the adhesive evenly covers the surface of the shoe sole. The slow-release design of the outlet, combined with the elastic properties of the coating roller, enables the adhesive to accurately fill the microstructure of the shoe sole and reduce local coating defects.

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0016] Please see Figure 1-4 A gluing device for shoe sole production includes a device platform 1, on which rotary joints 2 are rotatably connected, and four sets of rotary joints 2 are provided. The output ends of the four sets of rotary joints 2 are all fixedly connected to risers 3. The top ends of the four sets of risers 3 are all provided with gluing mechanisms. The bottom of the device platform 1 is provided with a glue cylinder 8, and four sets of infusion pumps 9 are provided on the glue cylinder 8. The output ends of the four sets of infusion pumps 9 are all fixedly connected to infusion pipes 10, and the top ends of the four sets of infusion pipes 10 are respectively rotatably connected to the input ends of the four sets of rotary joints 2. The device platform 1 is provided with a synchronous steering mechanism.

[0017] Through the above technical solution, four sets of rotary joints 2 are connected to the glue coating mechanism through the riser 3, forming four independent glue delivery channels. The glue in the glue cylinder 8 is pressurized by the delivery pump 9 and delivered to the rotary joint 2 through the delivery pipe 10, and then enters the storage tank 4 through the riser 3. In this design, the rotation connection function of the rotary joint 2 ensures that the riser 3 and the glue coating mechanism can be flexibly adjusted in angle, while the sealing of the glue delivery path is guaranteed by the dynamic sealing structure of the rotary joint 2 to avoid leakage. The design of four independent channels supports the simultaneous processing of different glue types or coating parameters, improving the multi-functionality of the equipment.

[0018] Specifically, the adhesive application mechanism includes a liquid storage tank 4 fixedly connected to the top of the riser 3, and a liquid outlet 5 is provided on the liquid storage tank 4.

[0019] Through the above technical solution, the liquid storage tank 4 serves as a temporary storage unit for the adhesive liquid. The liquid outlet 5 inside the tank can slowly release a small amount of adhesive liquid. During this process, the coating roller 7 can be moved to ensure that the adhesive layer on the surface of the coating roller 7 is uniform. The fixed connection design between the liquid storage tank 4 and the riser 3 ensures the stability of the adhesive liquid supply. The opening size and position of the liquid outlet 5 have been optimized by fluid mechanics so that the adhesive liquid can uniformly cover the surface of the coating roller 7 under the action of gravity and surface tension.

[0020] Specifically, a roller 6 is fixedly inserted through the inner side of the liquid storage tank 4, and an adhesive roller 7 is rotatably connected to the outer surface of the roller 6.

[0021] Through the above technical solution, the roller 6 inside the liquid storage tank 4 provides rotational support for the glue application roller 7. The high wear resistance and moderate elasticity of polyurethane enable it to accurately apply the glue to the surface of the shoe sole while avoiding mechanical damage to the shoe sole. During the rotation process, the glue application roller 7 (made of polyurethane) evenly transfers the glue in the liquid storage tank 4 to the contact surface of the shoe sole.

[0022] Specifically, the synchronous steering mechanism includes a motor 11 fixedly installed at the bottom of the device platform 1, and a pinion 12 is fixedly connected to the output end of the motor 11.

[0023] Through the above technical solution, the motor 11 serves as the power source, and the rotation of the rotating shaft 13 and the four-corner star plate 15 is achieved through the meshing transmission of the small gear 12 and the large gear 14, providing a basis for the synchronous reversal adjustment of the subsequent glue coating mechanism.

[0024] Specifically, a rotating shaft 13 is rotatably connected to the top of the device platform 1. A large gear 14 is fixedly sleeved on the outer surface of the rotating shaft 13, and the outer surface of the large gear 14 meshes with the outer surface of the small gear 12. A four-cornered star-shaped plate 15 is fixedly connected to the top of the rotating shaft 13.

[0025] Through the above technical solution, the four-corner star-shaped plate 15 fixed at the top of the rotating shaft 13 serves as a steering actuator. Its four guide slots 16 are distributed in a centrally symmetrical manner. When the rotating shaft 13 drives the four-corner star-shaped plate 15 to rotate, the oblique trajectory of the guide slots 16 forces the L-shaped guide rod 17 to slide along the slots.

[0026] Specifically, a guide bar hole 16 is provided on the four-corner star-shaped plate 15, and an L-shaped guide rod 17 is slidably connected in the guide bar hole 16. The end of the L-shaped guide rod 17 away from the four-corner star-shaped plate 15 is fixedly connected to the outer surface of the rotary joint 2.

[0027] Through the above technical solution, the sliding fit of the L-shaped guide rod 17 in the guide strip hole 16 realizes the directional steering of the rotary joint 2. When the four-corner star plate 15 is driven to rotate by the rotating shaft 13, the oblique path of the guide strip hole 16 forces the L-shaped guide rod 17 to produce radial displacement. At the same time, the other end of the L-shaped guide rod 17 is fixedly connected to the rotary joint 2, thereby converting the rotational motion of the four-corner star plate 15 into the synchronous rotation of the rotary joint 2. This mechanical conversion structure realizes multi-axis linkage through geometric constraints, ensuring that the steering angles of the four glue application mechanisms are consistent.

[0028] Working Principle: When applying adhesive to the sole, four sets of infusion pumps 9 deliver appropriate amounts of adhesive from the adhesive cylinder 8 through infusion pipes 10 to the input end of the rotary joint 2. The rotary joint 2 uses a dynamic sealing structure to achieve a rotatable connection between the infusion pipe 10 and the riser 3, ensuring that the adhesive enters the riser 3 in a sealed state. Finally, the adhesive is guided through the riser 3 to the top storage tank 4. The adhesive stored in the storage tank 4 is slowly released onto the surface of the coating roller 7 through the outlet 5. The size and position of the outlet 5 are optimized by fluid dynamics. During this process, the coating roller 7 is agitated, causing it to rotate on the roller shaft 6, so that the adhesive is evenly distributed across the entire coating roller 7. The coating roller 7 (made of polyurethane) is rotatably connected to the storage tank 4 through the roller shaft 6. Its high wear resistance and moderate elasticity can accurately adapt to the contour of the sole surface, avoiding mechanical damage. When the coating roller 7 passively rotates through contact friction with the sole, it evenly transfers the surface adhesive to the surface of the sole. In the sole coating area, when the coating direction needs to be adjusted, the synchronous steering mechanism is activated: the start motor 11 drives the small gear 12 to rotate, which in turn drives the large gear 14 and the rotating shaft 13 to rotate synchronously through gear meshing. The four-corner star-shaped plate 15 at the top of the rotating shaft 13 rotates accordingly. The guide strip holes 16 on it are centrally symmetrically distributed. During the rotation of the four-corner star-shaped plate 15, the oblique trajectory of the guide strip holes 16 forces the L-shaped guide rod 17 to slide along the holes, thereby causing the L-shaped guide rod 17 to deflect. Since the other end of the L-shaped guide rod 17 is fixedly connected to the rotary joint 2, the four sets of L-shaped guide rods 17 will eventually convert the rotational motion of the four-corner star-shaped plate 15 into the synchronous rotation of each rotary joint 2 during the synchronous deflection process. This, in turn, drives the entire coating mechanism to turn through the riser 3. The four sets of coating mechanisms achieve consistent angle adjustment through mechanical linkage (i.e., the direction of each coating roller 7 changes), adapting to the coating path requirements of different sole shapes.
