Description

Technical Field

[0001] This invention relates to the field of automated shoemaking technology, and in particular to a fully automated shoemaking system. Background Technology

[0002] With global economic development and rising living standards, the demand for footwear products is increasing, bringing unprecedented development opportunities to the footwear industry. At the same time, the market is placing higher demands on the quality, style, and production efficiency of footwear products. To meet market demands and enhance their competitiveness, footwear manufacturers are increasingly adopting automated production technologies to reduce production costs, improve efficiency, and enhance product quality.

[0003] In recent years, with the rapid development of robotics, sensor technology, and automation control technology, the level of automation in shoe manufacturing has significantly improved. Some advanced shoe manufacturing companies have achieved fully automated production from raw material processing, upper making, sole molding to complete shoe assembly. In the shoe manufacturing process, applying and spraying adhesive are crucial steps that directly affect the quality and lifespan of the shoes. The purpose of applying and spraying adhesive is to firmly bond the sole and upper together, ensuring the overall structural stability of the shoe. Existing automated adhesive application and spraying equipment has poor adaptability to different types of adhesives and shoes, requiring frequent equipment changes or parameter adjustments, increasing production costs and complexity. Summary of the Invention

[0004] To address the aforementioned issues, this invention achieves a highly efficient, high-quality, and stable fully automated shoe manufacturing system through efficient production processes, precise process handling, and a high degree of automation.

[0005] The technical solution adopted in this invention is: a fully automatic shoe-making system, including a rotary conveyor mechanism, a shoe last fixture, a shoe last fixing and locking mechanism, a shoe upper roughening mechanism, a chemical spraying mechanism, a first glue application mechanism, a second glue application mechanism, a glue rolling mechanism, and a transfer mechanism; the rotary conveyor mechanism is used for the cyclical transport of the shoe last fixture and for the shoe last fixture to sequentially pass through the shoe upper roughening mechanism, the chemical spraying mechanism, the first glue application mechanism, the second glue application mechanism, and the glue rolling mechanism; the shoe last fixing and locking mechanism is located at the inlet end of the rotary conveyor mechanism and is used for locking and fixing the shoe last fixture; the shoe upper roughening mechanism, The spraying mechanism, the first glue application mechanism, the second glue application mechanism, and the rolling glue mechanism are all equipped with transfer mechanisms that connect to the rotary conveyor mechanism for transferring shoe last fixtures. The rotary conveyor mechanism is equipped with multiple drying oven mechanisms, which are located behind the spraying mechanism, the first glue application mechanism, and the rolling glue mechanism. The shoe upper roughening mechanism is used to roughen the shoe uppers transferred by the transfer mechanism. The spraying mechanism is used to spray chemicals onto the roughened shoe uppers. The first and second glue application mechanisms are used to spray glue onto the shoe uppers. The rolling glue mechanism is used to roll glue onto the soles.

[0006] A further improvement to the above solution is that the transfer mechanism includes a transfer transmission device and a transfer gripping device. The transfer transmission device drives the transfer gripping device to move relative to the rotary conveyor mechanism to grip and transfer the shoe last fixture. One end of the shoe last fixture is provided with an alignment bushing. The transfer gripping device includes a gripping bracket, a gripping drive assembly, and a gripping opening assembly. The gripping bracket is mounted on the transfer transmission device, and the gripping drive assembly is mounted on the gripping bracket. The gripping opening assembly is provided with multiple opening clamping arms. The multiple opening clamping arms are evenly distributed in a circumferential direction. The gripping drive assembly drives the opening clamping arms to open in a columnar shape. The alignment bushing is provided with an alignment shaft hole. During gripping and transfer, the gripping opening assembly is inserted into the alignment shaft hole. Under the action of the gripping drive assembly, the opening clamping arms cooperate with the inner wall of the alignment shaft hole to grip and transfer the shoe last fixture.

[0007] A further improvement to the above solution is that the shoe last fixture includes a fixture base, a fixture support, a clamping device, and a clamping drive device. The fixture support is disposed on the fixture base, and the clamping device and the clamping drive device are respectively disposed at both ends of the fixture support. The clamping drive device is used to drive the clamping device to clamp and fix the shoe last. The fixture base is used for transmission on the rotary conveyor mechanism.

[0008] A further improvement to the above solution is that the jig base is provided with conveying pads on both sides for use with the conveying station, and the side of the conveying pad that contacts the conveying station is chrome-plated; multiple weight-reducing grooves are provided on both sides of the jig base; and multiple positioning bushings are provided on the jig base.

[0009] A further improvement to the above solution is that the shoe last fixing and locking mechanism includes a jig positioning device, a locking bracket, a locking drive device, and a locking pressing device. The jig positioning device is used for positioning the shoe last jig, the locking drive device is mounted on the locking bracket, and the locking pressing device is used to press and fix the shoe last onto the jig positioning device.

[0010] The beneficial effects of this invention are:

[0011] Compared to existing shoemaking systems, this invention offers significant improvements in production efficiency. The rotary conveyor mechanism enables the cyclical transport of shoe lasts and fixtures, allowing multiple shoemaking processes, such as upper roughening, chemical spraying, and glue application, to proceed sequentially and systematically, forming a continuous production line. The close coordination of these mechanisms reduces manual handling and waiting time, greatly improving overall shoemaking efficiency. Compared to traditional methods, more shoes can be produced in a shorter time. Regarding product quality control, the upper roughening mechanism precisely roughens the upper, increasing its surface roughness and facilitating better adhesion of subsequent chemicals and glues. The chemical spraying mechanism evenly applies chemicals to the roughened upper, providing a good foundation for glue bonding. The first and second glue application mechanisms spray glue onto the upper, while the roller application mechanism applies glue to the sole, ensuring even glue distribution and a strong bond between the upper and sole, thus improving shoe quality and durability. The shoe last fixing and locking mechanism automatically locks and secures the shoe last fixture at the feeding end. The docking of various mechanisms with the transfer mechanism enables automatic transfer of the shoe last fixture, reducing manual intervention and minimizing the impact of human factors on the production process, thus improving production stability and consistency. Multiple drying ovens located after key processes on the rotary conveyor mechanism can promptly dry the shoe uppers and soles after spraying chemicals and adhesives, accelerating the drying and curing of the chemicals and adhesives, further improving production efficiency and product quality. This invention achieves high efficiency, high quality, and stable shoe manufacturing through an efficient production process, precise process handling, and a high degree of automation.

[0040] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0041] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. Figures 1-21As shown, in one embodiment of the present invention, a fully automatic shoe-making system is disclosed, comprising a rotary conveyor mechanism 1, a shoe last fixture 2, a shoe last fixing and locking mechanism 3, a shoe upper roughening mechanism 4, a chemical spraying mechanism 5, a first glue application mechanism 6, a second glue application mechanism 7, a glue rolling mechanism 8, and a transfer mechanism 9. The rotary conveyor mechanism 1 is used for the cyclical transport of the shoe last fixture 2 and for the shoe last fixture 2 to sequentially pass through the shoe upper roughening mechanism 4, the chemical spraying mechanism 5, the first glue application mechanism 6, the second glue application mechanism 7, and the glue rolling mechanism 8. The shoe last fixing and locking mechanism 3 is disposed at the inlet end of the rotary conveyor mechanism 1 and is used for locking and fixing the shoe last fixture 2. The shoe upper roughening mechanism... 4. The spraying mechanism 5, the first glue application mechanism 6, the second glue application mechanism 7, and the rolling glue mechanism 8 are all equipped with transfer mechanisms 9 that connect to the rotary conveyor mechanism 1 for transferring the shoe last fixture 2. The rotary conveyor mechanism 1 is equipped with multiple drying oven mechanisms 11, located behind the spraying mechanism 5, the first glue application mechanism 6, and the rolling glue mechanism 8. The upper roughening mechanism 4 roughens the uppers transferred by the transfer mechanism 9. The spraying mechanism 5 sprays chemicals onto the roughened uppers. The first and second glue application mechanisms 6 and 7 spray glue onto the uppers. The rolling glue mechanism 8 applies glue to the soles. In terms of production efficiency, this embodiment achieves the cyclical transport of the shoe last fixture 2 through the rotary conveyor mechanism 1, allowing multiple shoemaking processes such as upper roughening, spraying chemicals, and applying glue to be carried out sequentially and orderly, forming a continuous production line. The close cooperation among various mechanisms reduces manual handling and waiting time, greatly improving the overall efficiency of shoemaking. Compared to traditional shoemaking methods, more shoes can be produced in a shorter time. In terms of product quality control, the upper roughening mechanism 4 precisely roughens the upper, increasing its surface roughness and facilitating better adhesion of subsequent chemicals and adhesives. The chemical spraying mechanism 5 evenly sprays chemicals onto the roughened upper, providing a good foundation for adhesive bonding. The first and second glue application mechanisms 6 and 7 spray adhesive onto the upper, and the roller application mechanism 8 applies glue to the sole, ensuring even glue distribution and a strong bond between the upper and sole, improving shoe quality and durability. The shoe last fixing and locking mechanism 3 automatically locks and fixes the shoe last fixture 2 at the feeding end. The docking of these mechanisms with the transfer mechanism 9 enables automatic transfer of the shoe last fixture 2, reducing manual intervention, minimizing the impact of human factors on the production process, and improving production stability and consistency. Multiple drying ovens 11 mounted on the rotary conveyor 1 are located after key processes, enabling timely drying of the shoe uppers and soles after the spraying of chemicals and adhesives. This accelerates the drying and curing of the chemicals and adhesives, further improving production efficiency and product quality. This embodiment achieves high efficiency, high quality, and stable shoe production through an efficient production process, precise process handling, and a high degree of automation.

[0043] See Figure 3As shown, the rotary conveyor mechanism 1 includes a first linear conveyor line 12, a second linear conveyor line 13, a first rotary conveyor device 14, and a second rotary conveyor device 15. The first linear conveyor line 12 and the second linear conveyor line 13 are arranged parallel to each other. The first rotary conveyor device 14 is located at one end of the first linear conveyor line 12 and the second linear conveyor line 13, and is used to connect the first linear conveyor line 12 and the second linear conveyor line 13. The second rotary conveyor device 15 is located at the other end of the first linear conveyor line 12 and the second linear conveyor line 13. The first linear conveyor line 12 and the second linear conveyor line 13 are both double-layer conveying devices. Specifically, both the first linear conveyor line 12 and the second linear conveyor line 13 are equipped with multiple conveying positioning devices 16, which are used to position the shoe last fixture 2. The multiple conveying positioning devices 16 correspond to the shoe last fixing and locking mechanism 3, the shoe upper roughening mechanism 4, the spraying mechanism 5, the first glue application mechanism 6, the second glue application mechanism 7, the rolling glue mechanism 8, and the transfer mechanism 9, respectively. In this embodiment, the first linear conveyor line 12 and the second linear conveyor line 13 are arranged in parallel and connected to form a loop through the first conveying rotary device 14 and the second conveying rotary device 15, realizing the cyclic transmission of the shoe last fixture 2. The cyclic conveying method allows the shoemaking process to continue continuously without the need for frequent manual handling and adjustment of the position of the shoe last fixture 2, greatly improving production efficiency. The double-layer conveyor design further increases conveying capacity, enabling the simultaneous processing of more shoe last fixtures 2 and further improving overall shoe production output. Multiple conveyor positioning devices 16 correspond to key processes such as the upper roughening mechanism 4 and the chemical spraying mechanism 5, accurately positioning the shoe last fixture 2 at the operating positions of each process. This ensures that each process accurately processes the upper and sole, improving the precision and quality of shoemaking. For example, the upper roughening mechanism 4 can uniformly roughen the upper under precise positioning, avoiding uneven roughening caused by inaccurate positioning, thus providing a good foundation for subsequent chemical spraying and glue application. The presence of the conveyor positioning devices 16 makes the connection between processes tighter and smoother. The shoe last fixture 2 can pass through each process sequentially according to a predetermined order, reducing waiting time and errors between processes and ensuring the continuity and stability of the shoemaking process.

[0044] See Figure 4As shown, the conveying and positioning device 16 includes a conveying and positioning base plate 161, a conveying and positioning cylinder 162, a conveying and lifting cylinder 163, a conveying and lifting base plate 164, and a lifting guide rod 165. The conveying and positioning base plate 161 is disposed on the first linear conveying line 12 and the second linear conveying line 13. The conveying and positioning cylinder 162 is disposed on the conveying and positioning base plate 161 and is used to position the shoe last 2 on the conveying line along the conveying direction. The conveying and lifting cylinder 163 is disposed on the lifting base plate. One end of the lifting guide rod 165 is disposed on the conveying and lifting base plate 164, and the other end is movably disposed on the conveying and positioning base plate 161 through a bushing. The conveying and lifting base plate 164 is used to position the shoe last 2 so that the shoe last 2 can be gripped by the transfer mechanism 9. In this embodiment, the conveying and positioning cylinder 162 is disposed on the conveying and positioning base plate 161, which can accurately position the shoe last 2 on the conveying line along the conveying direction. During the cyclical transport of the shoe last fixture 2 driven by the rotary conveyor mechanism 1, the shoe last fixture 2 may experience positional deviations due to various factors during transport. The function of the conveyor positioning cylinder 162 is to correct these deviations in a timely manner, ensuring that the shoe last fixture 2 is in an accurate position in the transport direction. This allows the shoe last fixture 2 to sequentially pass through various processes such as the upper roughening mechanism 4 and the spraying mechanism 5 along a predetermined trajectory, ensuring the orderly progress of the shoe manufacturing process, avoiding process errors caused by inaccurate positioning of the shoe last fixture 2, and improving production stability and product quality. The cooperation between the conveyor lifting cylinder 163 and the conveyor lifting base plate 164 provides a guarantee for the vertical positioning of the shoe last fixture 2. The conveyor lifting cylinder 163 is mounted on the lifting base plate and connected to the conveyor positioning base plate 161 through the lifting guide rod 165. When the shoe last fixture 2 reaches a specific position, the conveyor lifting cylinder 163 actuates, driving the conveyor lifting base plate 164 to rise and vertically position the shoe last fixture 2. Vertical positioning ensures that the shoe last fixture 2 accurately aligns with the transfer mechanism 9, facilitating the mechanism's gripping and transfer of the shoe last fixture 2 to the next process. Accurate vertical positioning reduces errors during transfer, improves success rate and efficiency, and thus accelerates the overall shoe manufacturing process. Furthermore, the lifting guide rod 165 is movably mounted on the conveying positioning base plate 161 via a bushing, providing stable guidance for the rising and falling of the conveying lifting base plate 164. This ensures the stability of the conveying lifting base plate 164 during movement, preventing swaying or tilting from affecting the positioning accuracy of the shoe last fixture 2.

[0045] See Figures 5-9As shown, the transfer mechanism 9 includes a transfer transmission device 91 and a transfer gripping device 92. The transfer transmission device 91 drives the transfer gripping device 92 to move relative to the rotary conveyor mechanism 1 to grip and transfer the shoe last fixture 2. One end of the shoe last fixture 2 is provided with an alignment bushing 21. The transfer gripping device 92 includes a gripping bracket 921, a gripping drive assembly 922, and a gripping opening assembly 923. The gripping bracket 921 is mounted on the transfer transmission device 91, and the gripping drive assembly 922... 2. The gripping and opening assembly 923, mounted on the gripping bracket 921, is provided with multiple opening clamping arms 924. These multiple opening clamping arms 924 are evenly distributed in a circumferential direction. The gripping drive assembly 922 drives the opening clamping arms 924 to open in a columnar shape. The alignment bushing 21 is provided with an alignment shaft hole 211. During gripping and transfer, the gripping and opening assembly 923 is inserted into the alignment shaft hole 211. Under the action of the gripping drive assembly 922, the opening clamping arms 924 engage with the inner wall of the alignment shaft hole 211 to grip and transfer the shoe last fixture 2. In this embodiment, the transfer transmission device 91 can drive the transfer gripping device 92 to move relative to the rotary conveyor mechanism 1, realizing the rapid transfer of the shoe last fixture 2 between different processes. After the rotary conveyor mechanism 1 sequentially transports the shoe last fixture 2 to each processing position, the transfer mechanism 9 can quickly grab the shoe last fixture 2 and transfer it to the next required process, reducing the dwell time of the shoe last fixture 2 between processes and greatly improving the production efficiency of the entire shoemaking process, making the shoemaking process more compact and continuous. Regarding gripping stability, the alignment bushing 21 and its alignment shaft hole 211 at one end of the shoe last fixture 2 are cleverly coordinated with the transfer gripping device 92. After the gripping opening component 923 of the transfer gripping device 92 is inserted into the alignment shaft hole 211, under the action of the gripping drive component 922, multiple circumferentially distributed opening clamping arms 924 open in a columnar shape, tightly fitting the inner wall of the alignment shaft hole 211. This ensures that the gripping force is evenly distributed across the shoe last fixture 2, preventing it from shaking or falling during the gripping process. This guarantees the stability of the shoe last fixture 2 during transfer, reducing production accidents and defect rates caused by unstable gripping. Thanks to the standardized design of the alignment bushing 21 and alignment hole 211, the transfer mechanism 9 can accurately grip and transfer the shoe last fixture 2 as long as it meets the corresponding specifications. This allows the fully automated shoe-making system to be applied to the production of shoes of different styles and specifications, improving the system's flexibility and applicability.

[0046] The gripping drive assembly 922 includes a gripping drive cylinder 925 and a gripping lever 926. The gripping drive cylinder 925 is mounted on the gripping bracket 921, and one end of the gripping lever 926 is connected to the drive end of the gripping drive cylinder 925. The gripping opening assembly 923 includes a fixed sleeve 9231, an opening shaft seat 9232, and a merging spring 9233. One end of the fixed sleeve 9231 is mounted on the gripping bracket 921. The opening shaft seat 9232 is used to mount the opening clamping arm 924 on the fixed sleeve 9231. The merging spring 9233 is... The clamping arms 924 are placed on the opening bearing seat 9232 for resetting the opening clamping arms 924. A drive connection hole 9241 is provided at the axis of each of the multiple opening clamping arms 924. An opening ramp 9242 is provided at the end of the drive connection hole 9241. One end of the end plate of the gripping lever 926 passes through the drive connection hole 9241 and is provided with an opening drive ramp 9261. The gripping drive cylinder 925 drives the gripping lever 926. With the cooperation of the opening ramp 9242 and the opening drive ramp 9261, the opening clamping arms 924 are driven to open to grip the inner wall of the alignment shaft hole 211. In this embodiment, the gripping drive cylinder 925 drives the gripping lever 926 to move, and the opening of the clamping arms 924 is controlled by the cooperation of the opening ramp 9242 and the opening drive ramp 9261. This inclined plane design precisely converts the linear motion of the cylinder into the opening action of the clamping arm 924, allowing it to open in a predetermined manner and amplitude, accurately engaging with the inner wall of the alignment shaft hole 211. This ensures that a suitable gripping force is applied accurately when gripping the shoe last fixture 2, preventing the fixture from falling or being loosely gripped due to inaccurate gripping. This greatly improves the reliability and stability of the gripping operation, thereby enhancing the continuity and stability of the entire shoe manufacturing process. The rapid response of the gripping drive cylinder 925 allows the clamping arm 924 to open and close quickly. When the shoe last fixture 2 reaches the designated position, the gripping drive cylinder 925 can drive the gripping lever 926 in a short time, causing the clamping arm 924 to open rapidly and complete the gripping action; after moving to the target position, it can quickly release. The efficient gripping and releasing process reduces the dwell time of the shoe last fixture 2 during transfer, improves the working efficiency of the transfer mechanism 9, and thus accelerates the production rhythm of the entire shoemaking system. The configuration of the merging spring 9233 provides a reliable guarantee for the reset of the opening clamping arm 924. After completing a gripping and transfer task, the merging spring 9233 enables the opening clamping arm 924 to quickly return to its initial state, preparing for the next gripping.

[0047] See Figures 10-15As shown, the shoe last fixture 2 includes a fixture base 22, a fixture support 23, a clamping device 24, and a clamping drive device 25. The fixture support 23 is mounted on the fixture base 22, and the clamping device 24 and clamping drive device 25 are respectively mounted at both ends of the fixture support 23. The clamping drive device 25 is used to drive the clamping device 24 to clamp and fix the shoe last. The fixture base 22 is used for transmission on the rotary conveyor mechanism 1. Conveying pads 221 for use with the conveying station are provided on both sides of the fixture base 22. The side of the conveying pad 221 that contacts the conveying station is chrome-plated. Multiple weight-reducing grooves are provided on both sides of the fixture base 22. The fixture base 22 is equipped with... There are multiple positioning bushings; specifically, the fixture bracket 23 is provided with a base plate 231, a support rod 232, an end plate 233, and a panel 234. The support rod 232 is used to connect the panel 234 to the base plate 231. The end plate 233 is located at one end of the base plate 231 and the panel 234. The end plate 233 is provided with a boss 235, which is used to connect the base plate 231 and the panel 234. The alignment bushing 21 is provided on the end plate 233. The panel 234 is provided with a shoe last support assembly 26, which is used for shoe last support. The shoe last support assembly 26 is provided with a height adjustment rod 261 for supporting shoe lasts of different sizes and heights. In this embodiment, the conveying pads 221 on both sides of the fixture base 22 play a key role. The side of the conveyor pad 221 that contacts the conveying station is chrome-plated, featuring a low coefficient of friction and high wear resistance. During transport on the rotary conveyor mechanism 1, the low coefficient of friction allows the shoe last fixture 2 to move smoothly, reducing jamming and resistance during transport and improving conveying efficiency. Simultaneously, the high wear resistance ensures that the conveyor pad 221 will not easily wear down during long-term use, extending the service life of the shoe last fixture 2 and reducing equipment maintenance costs. Furthermore, the conveyor pad 221 allows the shoe last fixture 2 to be placed stably on the conveying station, preventing shaking or shifting that could affect subsequent shoe-making processes, ensuring the continuity and stability of the entire shoe-making process. Multiple weight-reducing grooves on both sides of the fixture base 22 contribute to weight reduction. Reducing the weight of the shoe last fixture 2 lowers the load on the rotary conveyor mechanism 1, reducing energy consumption and improving equipment operating efficiency; it also facilitates the handling and adjustment of the shoe last fixture 2 by operators when necessary, improving operational convenience. The positioning bushing ensures precise positioning of the shoe last fixture 2 in each process. In conjunction with the conveying and positioning device 16, the positioning bushing ensures the shoe last fixture 2 accurately reaches the designated position, allowing processes such as upper roughing, chemical spraying, and glue application to be carried out accurately, thus improving the precision and quality of shoemaking.

The clamping drive device 25 includes a clamping output shaft 251, a synchronous drive wheel 252, and a clamping driven wheel 253. Bearings are provided at both ends of the clamping output shaft 251, connecting it to the base plate 231 and the front panel 234 respectively. One end of the clamping output shaft 251 extends to the outside of the front panel 234. The synchronous drive wheel 252 is mounted on the clamping output shaft 251, and the clamping driven wheel 253 is mounted on the clamping device 24. A synchronous belt 254 connects the synchronous drive wheel 252 and the clamping driven wheel 253.

The inner diameter of the clamping driven wheel 253 is the threaded inner diameter, and the outer diameter of the first pull rod 241 has a threaded portion 2411. The first pull rod 241 is driven to move up and down along the positioning groove 2311 by the threaded inner diameter of the clamping driven wheel 253 in conjunction with the threaded portion 2411. The clamping fixing seat 242 is provided with... On the surface of panel 234, the clamping slider 243 is disposed within the clamping fixing seat 242. One end of the first pull rod 241 is connected to the clamping slider 243 and slides downward under the action of the clamping driven wheel 253, driving the clamping slider 243 to slide within the clamping fixing seat 242. The clamping plate 244 is disposed on one side of the clamping slider 243 to clamp and fix the shoe last under the action of the clamping slider 243. The clamping fixing seat 242 is provided with a guide groove 2422, and the clamping slider 243 is provided with a guide slider 2431, which slides in the guide groove 2422. The clamping slider 243 is provided with a reset groove 2432 about the first pull rod 241 as the axis. A spring groove 2433 is provided on the side of hole 2341 facing the reset groove 2432. A reset spring is provided in the spring groove 2433, and the other end of the reset spring is used to abut against the bottom surface of the reset groove 2432 to assist in the reset of the slider 243. Specifically, the clamping device 24 also includes a second pull rod 245, an inner diameter clamping block 246, and a fixed slider 247. A fixed slide groove 2421 is provided on the upper surface of the clamping fixing seat 242. Two fixed sliders 247 are provided and are respectively provided at both ends of the fixed slide groove 2421, so that an inner diameter clamping groove is formed in the fixed slide groove 2421 with the first pull rod 241 as the axis. Two inner diameter clamping blocks 246 are provided and are arranged opposite to each other on the fixed slide groove 2421. On the slide groove 2421, two inner diameter clamping blocks 246 are provided with a pull rod slide groove 2461 on opposite sides.

The second pull rod 245 is provided on the pull rod slide groove 2461, and one end is connected to the first pull rod 241. The other end is provided with an inclined surface pushing part. The inclined surface pushing part is used to push the inner diameter clamping block 246 to move relative to the fixed slider 247 to clamp and fix the inner diameter hole of the shoe last. An inner diameter sliding spring is provided between the inner diameter clamping block 246 and the fixed slider 247 for the inner diameter clamping block 246 to reset. The inner diameter clamping block 246 includes a sliding part and a semi-cylindrical clamping push block.In this embodiment, regarding clamping stability, the first pull rod 241 and the clamping driven wheel 253 are threaded together, precisely converting the rotation of the driven wheel into the linear lifting and lowering motion of the first pull rod 241. This ensures stable and controllable sliding of the first pull rod 241 on the positioning groove 2311, thereby driving the clamping slider 243 to slide smoothly within the clamping fixing seat 242. The clamping plate 244 clamps the shoe last under the action of the clamping slider 243. Due to the stability of the movement, a uniform clamping force is applied to the shoe last, preventing it from shaking or shifting during shoemaking. This ensures the precise execution of subsequent processes such as roughing the upper, spraying chemicals, and applying glue, greatly improving shoemaking quality. The cooperation between the guide groove 2422 and the guide slider 2431 further enhances the stability and accuracy of the movement of the clamping slider 243. The guiding structure ensures that the clamping slider 243 can only slide along a predetermined trajectory, reducing unnecessary deviations and further improving clamping accuracy. The return spring ensures the continuity and reliability of the clamping action. After completing one clamping operation, the return spring allows the clamping slider 243 to quickly return to its original position, preparing for the next clamping operation and improving the efficiency of the shoe-making system. For clamping the inner diameter hole of the shoe last, the coordinated work of the second pull rod 245, the inner diameter clamping block 246, and the fixed slider 247 plays a crucial role. The cooperation between the inclined push part and the inclined surface of the pull rod cleverly converts the movement of the first pull rod 241 into the relative movement of the inner diameter clamping block 246, achieving effective clamping of the inner diameter hole of the shoe last. The inner diameter sliding spring ensures that the inner diameter clamping block 246 can smoothly return to its original position after clamping, ensuring the cyclical operation of the entire clamping device 24. The semi-cylindrical clamping push block design better conforms to the shape of the inner diameter hole of the shoe last, providing a more stable clamping force.

The structure of the shoe last loosening mechanism 10 is the same as that of the shoe last fixing and locking mechanism 3. In this embodiment, regarding shoe last positioning and fixing, the jig positioning device 31 can accurately position the shoe last jig 2, laying a good foundation for subsequent shoemaking processes. The coordinated operation of the locking drive device 33 and the locking clamping device 34 ensures that the shoe last can be stably fixed on the jig positioning device 31. The locking lifting module 332 drives the locking lifting base plate 331 to slide axially along the locking guide rod 323, so that the output connector 3331 can accurately align with the shoe last jig 2.

The locking clamping device 34 further presses the shoe last jig 2 to prevent the shoe last from shifting or shaking during processes such as upper roughening, spraying chemicals, and applying glue, ensuring the precision and quality of shoemaking. From the perspective of structural design rationality, the locking bracket 32 ​​has a stable and reliable structure. The locking base plate 321, locking support column 322, locking guide rod 323, and locking top plate 324 are interconnected, providing solid support for the entire locking mechanism. The stable structure can withstand various forces during the shoe-making process, ensuring the normal operation of the mechanism. The last-releasing mechanism 10 is crucial for the continuity of the shoe-making process. Located behind the glue-rolling mechanism 8, its structure is the same as the last-fixing and locking mechanism 3.After the shoe last has undergone processes such as gluing, the shoe last releasing mechanism 10 can release the shoe last in a timely and accurate manner, allowing it to smoothly enter the next process. This ensures the continuity of the shoe manufacturing process and improves production efficiency. Since the shoe last fixing and locking mechanism 3 and the shoe last releasing mechanism 10 have the same structure, the types and number of parts can be reduced during the manufacturing, installation, and maintenance of the equipment, lowering costs and improving the reliability and maintainability of the equipment.

The drive end of the glue application drive module 834 is connected to the glue application roller 835 and is used to drive the glue application roller 835 to rotate for applying glue to the shoes. In this embodiment, the glue blocking device 82 plays a key role in glue control. Side baffles 821 are arranged opposite each other on both sides of the transfer mechanism 9 and are equipped with glue blocking brushes. When the transfer mechanism 9 picks up the shoe last fixture 2, the glue blocking brushes can effectively prevent glue from splashing and overflowing.

In this embodiment, from the perspective of glue supply stability, the glue storage tank 201 provides sufficient glue reserves for the shoe-making process. It can store a large amount of glue at once, reducing the need for frequent glue additions, ensuring the continuity of the shoe-making process, avoiding production interruptions due to insufficient glue supply, and improving production efficiency. The weighing module 202 can measure the weight of the glue in the storage tank 201 in real time. Through precise monitoring of the glue weight, staff can promptly understand the glue usage. When the glue weight approaches the preset lower limit, glue replenishment can be arranged in advance to avoid glue shortages. Simultaneously, the data from the weighing module 202 helps in the statistical analysis of glue usage, thereby optimizing glue usage strategies and reducing production costs. The temperature control module 203 plays a crucial role in ensuring the quality and performance of the glue. Glue performance is often affected by temperature; under different temperature conditions, the viscosity, flowability, and adhesion of the glue may change. The temperature control module 203 can maintain the glue within a constant temperature range, ensuring that the glue is always in optimal working condition. This allows the glue to be evenly applied to the shoes during the glue application operations of the first glue application mechanism 6, the second glue application mechanism 7, and the roller glue application mechanism 8, improving the adhesion and fit of the glue, and thus enhancing the manufacturing quality of the shoes. Multiple glue supply mechanisms 20 correspond to different glue application mechanisms, achieving precise glue supply. Based on the different needs of each glue application mechanism, the glue supply mechanism 20 can provide the appropriate quantity and quality of glue, avoiding glue waste and insufficient supply problems. Precise glue supply improves the operational efficiency and stability of the entire shoe manufacturing system.
