Description

Technical Field

[0001] This utility model relates to the field of shoe material manufacturing technology, specifically to a shoe material gluing machine. Background Technology

[0002] Currently, gluing shoe materials is a core step in the shoe manufacturing process, directly affecting the bonding strength, durability, and production efficiency of the shoes.

[0003] Traditional shoe material gluing machines, such as the Chinese utility model patent with authorization announcement number CN201758897U and patent name "A Shoe Material Gluing Machine," generally adopt a single-application structure, mainly designed for single-layer gluing. However, with the increasing demands for bonding strength in high-performance sports shoes and multi-functional casual shoes, double gluing (i.e., applying glue and curing the same shoe material twice consecutively) has gradually become a key process for improving the interlayer bonding strength of shoe materials. To achieve double gluing, the current industry adopts a "segmented production" model: after the first gluing, the semi-finished product needs to be unloaded from the winding device, manually transported to the unwinding station for reloading, and a second independent gluing process needs to be performed. This is not only inconvenient to operate and inefficient, but also, if the first glue layer is not fully cured during layer bonding, the interfacial bonding strength between the glue layers can be reduced during the second gluing, leading to glue layer peeling. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a shoe material gluing machine that can achieve continuous double gluing of shoe materials. This not only improves work efficiency but also effectively enhances the interfacial bonding force between the glue layers, thus ensuring the quality of the double gluing of shoe materials. The technical solution adopted is as follows:

[0005] A shoe material gluing machine includes a frame, a shoe material unwinding device, a bottom adhesive coating and shaping mechanism, and a rewinding device. The bottom adhesive coating and shaping mechanism includes a first gluing device and a first drying device. The shoe material unwinding device, the first gluing device, the first drying device, and the rewinding device are all mounted on the frame and arranged sequentially along the conveying direction of the shoe material. The machine is characterized in that it further includes an air-cooling device, a material storage mechanism, and a reinforcing adhesive coating and shaping mechanism, all located between the bottom adhesive coating and shaping mechanism and the rewinding device. The reinforcing adhesive coating and shaping mechanism includes a second gluing device and a second drying device. The air-cooling device, the material storage mechanism, the second gluing device, and the second drying device are all mounted on the frame and arranged sequentially along the conveying direction of the shoe material. The air-cooling device includes a first blowing unit and a second blowing unit, which blow air towards the front and back of the shoe material, respectively.

[0006] During operation, the shoe material unwinding device stores shoe material rolls and continuously releases shoe materials (such as leather). The shoe materials are conveyed from front to back, sequentially passing through the bottom adhesive coating and setting mechanism, the air cooling device, the storage mechanism, and the reinforcing adhesive coating and setting mechanism. When the shoe materials pass through the bottom adhesive coating and setting mechanism, the first gluing device applies the bottom adhesive to the back of the shoe materials, and then the first drying device heats and dries the bottom adhesive to rapidly cure it, completing the first gluing. When the shoe materials pass through the air cooling device, the first and second blowing units blow air towards the front and back of the shoe materials, respectively, causing the temperature of the shoe materials and the bottom adhesive to drop rapidly, ensuring that the bottom adhesive is fully cured and preventing mutual dissolution between adhesive layers during the second gluing. When the shoe materials pass through the storage mechanism, the storage mechanism automatically positions the shoe materials within the bottom adhesive coating and setting machine. The material storage mechanism maintains appropriate tension between the bottom layer adhesive coating and shaping mechanism and the reinforcing adhesive coating and shaping mechanism. If the segment of the shoe material between the bottom layer adhesive coating and shaping mechanism and the reinforcing adhesive coating and shaping mechanism becomes longer due to thermal expansion and contraction or front-to-back differential speed, the material storage mechanism can store it to maintain appropriate tension. If the segment of the shoe material between the bottom layer adhesive coating and shaping mechanism and the reinforcing adhesive coating and shaping mechanism becomes shorter due to thermal expansion and contraction or front-to-back differential speed, the material storage mechanism can automatically release part of the shoe material to maintain appropriate tension. When the shoe material passes through the reinforcing adhesive coating and shaping mechanism, the second gluing device first applies reinforcing adhesive to the bottom layer surface, and then the second drying device heats and dries the adhesive layer to quickly cure it, completing the second gluing. Finally, the winding device winds up the double-glued shoe material. This shoe material gluing machine completes the first and second gluing of shoe materials through a base adhesive coating and shaping mechanism and a reinforcing adhesive coating and shaping mechanism, respectively. It can achieve continuous double gluing of shoe materials, thereby improving work efficiency. Furthermore, an air-cooling device is installed between the base adhesive coating and shaping mechanism and the reinforcing adhesive coating and shaping mechanism. The air-cooling method rapidly reduces the temperature of the shoe material and base adhesive after the first gluing, ensuring that the base adhesive is fully cured and preventing mutual dissolution between adhesive layers during the second gluing. This improves the interfacial bonding force between adhesive layers and helps to ensure the quality of gluing of shoe materials.

[0007] As a preferred embodiment of this utility model, the first drying device includes a first heating roller, a first drive motor, and at least one first pressure roller. The first drive motor is mounted on a frame, and the first heating roller is rotatably mounted on the frame and driven by the power output shaft of the first drive motor. The first pressure roller is disposed on one side of the first heating roller, and the first pressure roller and the first heating roller press against each other and rotate relative to each other. When the shoe material passes through the first drying device, the first heating roller rotates continuously under the drive of the first drive motor, and the first pressure roller and the first heating roller press against each other and rotate relative to each other, causing the shoe material to pass between the first pressure roller and the first heating roller, and then wrap around the roller surface of the first heating roller. Thus, the roller surface of the first heating roller can be used to heat and dry the adhesive layer on the shoe material, so that it can be quickly cured to form the bottom adhesive.

[0008] As a further preferred embodiment of this utility model, the first drying device further includes at least one first swing mechanism. The number of first swing mechanisms is the same as the number of first pressure rollers and they correspond one-to-one. The first swing mechanism includes a first swing shaft, a first swing frame, and a first cylinder. The first end of the first swing frame is hinged to the frame via the first swing shaft. The corresponding first pressure roller is rotatably mounted on the second end of the first swing frame and parallel to the first swing shaft. The cylinder body of the first cylinder is hinged to the frame, and the piston rod of the first cylinder is hinged to the middle of the first swing frame. With this structure, the first cylinder can drive the first swing frame and the first pressure roller to swing around the first swing shaft toward the roller surface of the first heating roller, ensuring that the first pressure roller and the first heating roller remain in a mutually pressing state. Furthermore, the elastic force of the first cylinder can be used to make the first drying device adapt to the traction of shoe materials of different thicknesses and the heating and drying of the bottom adhesive.

[0009] As a preferred embodiment of this utility model, the first blowing unit includes multiple first blowers arranged side by side, with the air outlet of each first blower facing the front of the shoe material; the second blowing unit includes multiple second blowers arranged side by side, with the air outlet of each second blower facing the back of the shoe material. When the shoe material passes through the air-cooling device, the first blowers of the first blowing unit blow air towards the front of the shoe material, and the second blowers of the second blowing unit blow air towards the back of the shoe material and the bottom adhesive, causing the temperature of the shoe material and the bottom adhesive to drop rapidly, ensuring that the bottom adhesive is fully cured.

[0010] As a preferred embodiment of this utility model, the second drying device includes a second heating roller, a second drive motor, and at least one second pressure roller. The second drive motor is mounted on a frame, and both the second heating roller and the second pressure roller are rotatably mounted on the frame and drively connected to the power output shaft of the second drive motor. The second pressure roller is disposed on one side of the second heating roller, and the second pressure roller and the second heating roller press against each other and rotate relative to each other. When the shoe material passes through the second drying device, the second heating roller rotates continuously under the drive of the second drive motor, and the second pressure roller and the second heating roller press against each other and rotate relative to each other, causing the shoe material to pass between the second pressure roller and the second heating roller, and then wrap around the roller surface of the second heating roller. Thus, the roller surface of the second heating roller can be used to heat and dry the reinforcing adhesive on the bottom layer adhesive, so that it can be quickly cured to form reinforcing adhesive.

[0011] As a further preferred embodiment of this utility model, the second drying device further includes at least one second swing mechanism. The number of second swing mechanisms is the same as the number of second pressure rollers and they correspond one-to-one. The second swing mechanism includes a second swing shaft, a second swing frame, and a second cylinder. The first end of the second swing frame is hinged to the frame via the second swing shaft. The second pressure roller is rotatably mounted on the second end of the second swing frame and parallel to the second swing shaft. The cylinder body of the second cylinder is hinged to the frame, and the piston rod of the second cylinder is hinged to the middle of the second swing frame. With this structure, the second cylinder can drive the second swing frame and the second pressure roller to swing around the second swing shaft toward the roller surface of the second heating roller, ensuring that the second pressure roller and the second heating roller remain in a mutually pressing state. Furthermore, the elastic force of the second cylinder can be used to make the second drying device adapt to the traction of shoe materials of different thicknesses and the heating and drying of the reinforcing rubber.

[0012] As a preferred embodiment of this utility model, the material storage mechanism includes a third swing shaft, a third swing frame, a gas spring, and a third pressure roller. The first end of the third swing frame is hinged to the frame via the third swing shaft. The third pressure roller is rotatably mounted on the third end of the third swing frame and parallel to the third swing shaft. One end of the gas spring is hinged to the frame, and the other end is hinged to the middle of the third swing frame. With this structure, the gas spring can drive the third swing frame and the third pressure roller to swing around the third swing shaft toward the surface of the segment of shoe material between the bottom adhesive coating and shaping mechanism and the reinforcing adhesive coating and shaping mechanism, ensuring that the third pressure roller remains in close contact with the surface of the shoe material. This achieves the material storage function, and the elasticity of the gas spring maintains a suitable tension in the segment of shoe material between the bottom adhesive coating and shaping mechanism and the reinforcing adhesive coating and shaping mechanism.

[0013] In a preferred embodiment of this invention, the frame includes a front support frame, a rear support frame, and a gantry frame, with the gantry frame connected between the top of the front support frame and the top of the rear support frame. The shoe material unwinding device, the first gluing device, and the first drying device are all mounted on the front support frame; the material storage mechanism, the second gluing device, the second drying device, and the winding device are all mounted on the rear support frame; and the first blowing unit and the second blowing unit are both mounted on the gantry frame. This allows for a more compact overall structure and a smaller footprint for the shoe material gluing machine.

[0014] Typically, multiple guide rollers are provided between the aforementioned shoe material unwinding device and winding device, which can guide and tension the conveyed shoe material.

[0015] The aforementioned shoe material unwinding device, first gluing device, second gluing device, and winding device can adopt existing conventional structures and belong to existing technology, so they will not be described in detail here.

[0016] Compared with the prior art, this utility model has the following advantages:

[0017] This shoe material gluing machine completes the first and second gluing of shoe materials through a base adhesive coating and shaping mechanism and a reinforcing adhesive coating and shaping mechanism, respectively. It can achieve continuous double gluing of shoe materials, thereby improving work efficiency. An air-cooling device is set between the base adhesive coating and shaping mechanism and the reinforcing adhesive coating and shaping mechanism. The air-cooling method rapidly drops the temperature of the shoe material and base adhesive after the first gluing, ensuring that the base adhesive is fully cured and avoiding mutual solubility between adhesive layers during the second gluing. This can improve the interfacial bonding force between adhesive layers and help ensure the quality of double gluing of shoe materials. Attached Figure Description

[0021] In this embodiment, the frame 1 includes a front support frame 11, a rear support frame 12, and a gantry frame 13, with the gantry frame 13 connected between the top of the front support frame 11 and the top of the rear support frame 12. The shoe material unwinding device 2, the first gluing device 31, and the first drying device 32 are all mounted on the front support frame 11, while the material storage mechanism 5, the second gluing device 61, the second drying device 62, and the winding device 7 are all mounted on the rear support frame 12. The first blowing unit 41 and the second blowing unit 42 are both mounted on the gantry frame 13. This allows for a more compact overall structure and a smaller footprint for the shoe material gluing machine.

[0022] In this embodiment, the first drying device 32 includes a first heating roller 321, a first drive motor (not shown in the figure), and two first pressure rollers 323. The first drive motor is mounted on the frame 1. The first heating roller 321 is rotatably mounted on the frame 1 and is connected to the power output shaft of the first drive motor. The two first pressure rollers 323 are arranged on one side of the first heating roller 321. The two first pressure rollers 323 are pressed against the first heating roller 321 and rotate relative to each other.

[0023] In this embodiment, the first blowing unit 41 includes a plurality of first blowers 411 arranged side by side, and the air outlet of each first blower 411 faces the front of the shoe material 20; the second blowing unit 42 includes a plurality of second blowers 421 arranged side by side, and the air outlet of each second blower 421 faces the back of the shoe material 20.

[0024] In this embodiment, the second drying device 62 includes a second heating roller 621, a second drive motor (not shown in the figure), and two second pressure rollers 623. The second drive motor is mounted on the frame 1. The second heating roller 621 is rotatably mounted on the frame 1 and is connected to the power output shaft of the second drive motor. The two second pressure rollers 623 are disposed on one side of the first heating roller 321. The two second pressure rollers 623 and the second heating roller 621 press against each other and rotate relative to each other.

[0025] In this embodiment, the storage mechanism 5 includes a third swing shaft 51, a third swing frame 52, a gas spring 53, and a third pressure roller 54. The first end of the third swing frame 52 is hinged to the frame 1 via the third swing shaft 51. The third pressure roller 54 is rotatably mounted on the third end of the third swing frame 52 and is parallel to the third swing shaft 51. One end of the gas spring 53 is hinged to the frame 1, and the other end of the gas spring 53 is hinged to the middle of the third swing frame 52.

[0026] In this embodiment, a plurality of guide rollers 8 are provided between the shoe material unwinding device 2 and the winding device 7, which can guide and tension the conveyed shoe material 20.

[0027] The working principle of this shoe material gluing machine is briefly described below:

[0028] During operation, the shoe material unwinding device 2 stores shoe material rolls and continuously releases shoe material 20 (such as leather). The shoe material 20 is conveyed from front to back, passing sequentially through the bottom adhesive coating and shaping mechanism 3, the air cooling device 4, the material storage mechanism 5, and the reinforcing adhesive coating and shaping mechanism 6. When the shoe material 20 passes through the bottom adhesive coating and shaping mechanism 3, the first gluing device 31 first coats the back of the shoe material 20 with bottom adhesive 201, and then the first drying device 32 heats and dries the bottom adhesive 201 to complete the first gluing. When the shoe material 20 passes through the first drying device 32, the first heating roller 321 rotates continuously under the drive of the first drive motor. The first pressure roller 323 presses against the first heating roller 321 and rotates relative to each other, driving the shoe material 20 to pass between the first pressure roller 323 and the first heating roller 321, and then wraps around the roller surface of the first heating roller 321. Thus, the roller surface of the first heating roller 321 can be used to heat and dry the adhesive layer on the shoe material 20, so that it can be quickly cured to form the bottom adhesive 201. When the shoe material 20 passes through the air-cooling device 4, the first blowers 411 of the first blowing unit 41 blow air towards the front of the shoe material 20, and the second blowers 421 of the second blowing unit 42 blow air towards the back of the shoe material 20 and the bottom adhesive 201, causing the temperature of the shoe material 20 and the bottom adhesive 201 to drop rapidly, ensuring that the bottom adhesive 201 is fully cured and preventing mutual dissolution between adhesive layers during secondary adhesive application. When the shoe material 20 passes through the storage mechanism 5, the storage mechanism 5 can automatically maintain the appropriate tension of the segment of the shoe material 20 between the bottom adhesive coating and shaping mechanism 3 and the reinforcing adhesive coating and shaping mechanism 6. If the segment of the shoe material 20 between the bottom adhesive coating and shaping mechanism 3 and the reinforcing adhesive coating and shaping mechanism 6 becomes longer due to thermal expansion and contraction or front-to-back differential speed, the gas spring 53 drives the third swing frame 52 and the third pressure roller 54 to rotate around the third swing axis 51 towards the segment of the shoe material 20 between the bottom adhesive coating and shaping mechanism 3 and the reinforcing adhesive coating and shaping mechanism 6. The third pressure roller 54 oscillates to ensure that the surface of the shoe material 20 remains in close contact with the surface of the shoe material 20, thereby realizing the material storage function and using the elastic force of the gas spring 53 to maintain the appropriate tension of the shoe material 20. If the segment of the shoe material 20 between the bottom adhesive coating and shaping mechanism 3 and the reinforcing adhesive coating and shaping mechanism 6 becomes shorter due to thermal expansion and contraction or front-rear differential speed, the third pressure roller 54 oscillates away from the surface of the shoe material 20 under the action of the shoe material 20, which can automatically release part of the shoe material 20 and use the elastic force of the gas spring 53 to maintain the appropriate tension of the shoe material 20.When the shoe material 20 passes through the reinforcing adhesive coating and shaping mechanism 6, the second gluing device 61 first coats the bottom layer surface with reinforcing adhesive 202, and then the second drying device 62 heats and dries the adhesive layer to quickly cure it, completing the second gluing process. When the shoe material 20 passes through the second drying device 62, the second heating roller 621 rotates continuously under the drive of the second drive motor. The second pressure roller 623 presses against the second heating roller 621 and rotates relative to it, causing the shoe material 20 to pass between the second pressure roller 623 and the second heating roller 621, and then wrap around the roller surface of the second heating roller 621. Thus, the roller surface of the second heating roller 621 can be used to heat and dry the reinforcing adhesive 202 on the bottom layer adhesive 201, allowing it to quickly cure and form the reinforcing adhesive 202. Finally, the winding device 7 winds up the double-glued shoe material 20.
