Description

Technical Field

[0001] This utility model relates to the field of sports shoe technology, and in particular to a sports shoe edge processing device. Background Technology

[0002] With the development of shoe manufacturing machinery technology, shoe edge processing equipment has played a crucial role in improving production efficiency and processing quality. As an important category in footwear production, the edge processing technology of athletic shoes directly impacts the aesthetics, durability, and comfort of the finished product. Existing shoe edge processing equipment is mostly concentrated on single processes such as gluing, cutting, and polishing, and in recent years has gradually developed towards automation and integration. However, in practical applications, existing equipment still suffers from problems such as poor process coordination, fragmented processing flows, and excessive manual intervention, making it difficult to meet the needs of large-scale, high-quality production of athletic shoes.

[0003] A search revealed a shoe edge processing device with publication number CN108835773B, published on August 18, 2020. This patent provides a shoe edge processing device comprising a working platform, a shoe last driving mechanism, a roller mechanism, a glue-applying wheel, a cutting mechanism, and a push-link module. Multiple sets of push-links control the cutting and limiting actions, achieving automatic cutting and positioning of the shoe edge. While this device ensures uniform force on the shoe edge and improves work efficiency, its function is mainly focused on cutting and limiting the shoe edge material, lacking integrated design for subsequent key processes such as sanding and cleaning. Furthermore, the device lacks an automatic loading and unloading system and a multi-station transfer structure, resulting in the need for manual intervention to transfer workpieces throughout the processing, limiting its automation level and making it difficult to adapt to the needs of continuous production lines.

[0004] A search revealed a patent for a sports shoe edge processing device, publication number CN114190656B, published on June 27, 2023. This patent discloses a sports shoe edge processing device comprising a sole plate, a loading worktable, a first cleaning worktable, a grinding worktable, and a second cleaning worktable. It utilizes a grooved wheel component to achieve orderly flow of workpieces between each station, and combines a cam and a flat-bottomed driven plate to complete loading and unloading. This device achieves fully automated operation of the entire process, including loading, dust removal, grinding, and re-cleaning, significantly improving processing quality and efficiency. However, the device still has some shortcomings in practical applications: First, each workbench is fixed on the base plate, and the structural layout is not adjustable, making it difficult to adapt to the processing needs of different models or sizes of athletic shoe edges; Second, the cleaning station uses brush rollers and sponge rollers for dust removal, which has limited effectiveness in removing firmly adhered glue residue or dust, and is prone to causing residual pollution that affects the subsequent polishing quality; Third, the polishing head is a fixed abrasive head, which cannot automatically adjust the polishing angle and pressure according to the curvature of the shoe edge, and there is a risk of uneven polishing or excessive wear in some areas.

[0005] The aforementioned problems indicate that existing shoe edge processing devices still have significant shortcomings in terms of functional integration, structural flexibility, and processing adaptability. This is particularly true when facing the demands of producing a wide variety of sports shoes in small batches with high precision, making it difficult to balance both efficiency and quality. Therefore, there is an urgent need for a new type of sports shoe edge processing device with a reasonable structure, complete processes, strong adaptability, and a high degree of automation. This device should overcome the shortcomings of existing technologies, such as fragmented processes, inconvenient adjustments, and poor cleaning and polishing effects, thereby further improving the level of intelligence and production efficiency in sports shoe manufacturing. Utility Model Content

[0006] This utility model relates to a processing device for the edge of athletic shoes, including a base, a multi-functional workstation module, a flexible adjustment mechanism, a high-efficiency cleaning unit, and an adaptive polishing component. The multi-functional workstation module is mounted on the base, and flexible adjustment mechanisms are respectively arranged on both sides of the multi-functional workstation module. A high-efficiency cleaning unit is mounted on the top of the flexible adjustment mechanism, and an adaptive polishing component is connected to one side of the high-efficiency cleaning unit.

[0007] The multi-functional workstation module includes a rotary disk, a drive motor, positioning fixtures, and a slide rail assembly. The drive motor is embedded in the center of the base, and the rotary disk is fixedly connected to the top of the output shaft of the drive motor. Multiple positioning fixtures are evenly distributed on the outer edge of the rotary disk. The positioning fixtures are fixed to the surface of the rotary disk by bolts, and the bottom of the positioning fixtures is provided with a sliding groove. The slide rail assembly is embedded in the sliding groove, and the two ends of the slide rail assembly are respectively fixed to the inner wall of the rotary disk.

[0008] The flexible adjustment mechanism includes a lifting column, an adjusting arm, a guide rod, and a locking component. The lifting column is symmetrically installed on both sides of the base. The top of the lifting column is hinged to the adjusting arm. One end of the adjusting arm is rotatably connected to the lifting column via a pin, and the other end is connected to the high-efficiency cleaning unit via the guide rod. A spring is sleeved on the outer wall of the guide rod, and the two ends of the spring abut against the adjusting arm and the high-efficiency cleaning unit, respectively. A locking component is provided in the middle of the adjusting arm. The locking component is screwed into the adjusting arm via a thread to limit the swing angle of the adjusting arm.

[0009] The high-efficiency cleaning unit includes a vacuum cleaner head, a high-pressure air nozzle, a scraper, and a dust collection box. The vacuum cleaner head is fixedly installed at the end of the adjusting arm. The bottom of the vacuum cleaner head is equipped with a scraper, which is fixed to the lower end face of the vacuum cleaner head by screws. The front end of the scraper is arc-shaped to conform to the contour of the shoe edge. A high-pressure air nozzle is provided on one side of the vacuum cleaner head, which is connected to an external air source through a pipe. The rear end of the vacuum cleaner head is connected to the dust collection box through a hose, and the dust collection box is fixed to one side of the base.

[0010] The adaptive grinding assembly includes a grinding head, a pressure sensor, an angle adjuster, and a telescopic rod. The grinding head is movably connected to one end of the telescopic rod via the angle adjuster. The angle adjuster has an internal universal ball joint structure, the outer wall of which fits tightly against the inner cavity of the angle adjuster. A pressure sensor is mounted on the side of the angle adjuster and is connected to the control system via a signal line. The other end of the telescopic rod is fixed to the end of the adjusting arm. An electric push rod is located inside the telescopic rod, and its output end is fixedly connected to the bottom of the angle adjuster.

[0011] This invention utilizes a multi-functional workstation module design, employing a rotary table to drive a positioning fixture, enabling the automatic transfer of workpieces between different workstations. This reduces the need for manual intervention and improves processing efficiency. The positioning fixture is connected to the rotary table via a slide rail assembly, allowing its position to be flexibly adjusted according to the workpiece size, thus adapting to the processing needs of different models or sizes of athletic shoe edges.

[0012] The flexible adjustment mechanism, through the cooperation of the lifting column and adjusting arm, enables the height and angle adjustment of the efficient cleaning unit and the adaptive polishing component, ensuring that they can precisely act on different parts of the shoe edge. The combination design of the guide rod and spring can absorb vibration during equipment operation, ensuring the stability of cleaning and polishing operations.

[0013] The high-efficiency cleaning unit combines a vacuum suction head with a high-pressure air nozzle. The scraper performs initial cleaning of the shoe edge surface, the high-pressure air nozzle blows away residual particles, and finally the vacuum suction head sucks the dust into the dust collection box, which significantly improves the cleaning effect and avoids residual pollution from glue scraps or dust.

[0014] The adaptive sanding assembly, through the coordinated operation of an angle adjuster and a pressure sensor, automatically adjusts the angle of the sanding head and the applied pressure according to the curvature of the shoe edge, avoiding uneven sanding or excessive wear, thereby improving sanding quality. The electric push rod within the telescopic rod further enhances the flexibility of the sanding head, enabling it to quickly respond to different processing needs.

[0015] This utility model solves the problems of existing shoe edge processing devices, such as scattered processes, inconvenient adjustment, and poor cleaning and polishing effects, through the above-mentioned technical solution. At the same time, it has the characteristics of reasonable structure, complete process, and strong adaptability, which significantly improves the level of intelligence and production efficiency of sports shoe manufacturing.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Specific implementation examples are given below.

[0023] like Figure 1 As shown, the overall structure of this utility model includes a base 1, a multi-functional workstation module 2, a flexible adjustment mechanism 3, a high-efficiency cleaning unit 4, and an adaptive polishing component 5. The base 1 serves as the fundamental support component of the entire device, with a flat upper surface and sufficient strength to support other functional modules. The multi-functional workstation module 2 is installed at the center of the base 1, with flexible adjustment mechanisms 3 symmetrically arranged on both sides. The top of the flexible adjustment mechanism 3 is connected to the high-efficiency cleaning unit 4 via a guide rod 12, and one side of the high-efficiency cleaning unit 4 is connected to the adaptive polishing component 5. The specific implementation methods of each component, their connection relationships, and operating principles are described in detail below with reference to the accompanying drawings.

[0024] like Figure 2As shown, the multi-functional workstation module 2 consists of a rotary disk 6, a drive motor 7, positioning fixtures 8, and a slide rail assembly 9. The drive motor 7 is embedded in the center of the base 1, with its output shaft vertically upward and fixedly connected to the rotary disk 6. The rotary disk 6 has a circular structure, with multiple positioning fixtures 8 evenly distributed along its outer edge. The positioning fixtures 8 are fixed to the surface of the rotary disk 6 by bolts, allowing them to be disassembled or replaced as needed. Each positioning fixture 8 has a groove at its bottom, within which a slide rail assembly 9 is embedded. Both ends of the slide rail assembly 9 are fixed to the inner wall of the rotary disk 6. The design of the slide rail assembly 9 allows for fine-tuning of the positioning fixtures 8 along the groove direction, thus adapting to the processing requirements of different sizes of athletic shoe edges. When the drive motor 7 starts, its output shaft drives the rotary disk 6 to rotate, thereby achieving automatic transfer of the positioning fixtures 8 between different workstations. This design reduces the need for manual intervention while improving the efficiency of workpiece transfer.

[0025] like Figure 3 As shown, the flexible adjustment mechanism 3 includes a lifting column 10, an adjusting arm 11, a guide rod 12, and a locking element 13. The lifting column 10 is symmetrically installed on both sides of the base 1, and its top end is hinged to the adjusting arm 11 via a pin. One end of the adjusting arm 11 is rotatably connected to the lifting column 10 via a pin, and the other end is connected to the high-efficiency cleaning unit 4 via the guide rod 12. A spring is sleeved on the outer wall of the guide rod 12, and the two ends of the spring abut against the adjusting arm 11 and the high-efficiency cleaning unit 4 respectively, which plays a role in buffering vibration. A locking element 13 is provided in the middle of the adjusting arm 11, and the locking element 13 is screwed into the adjusting arm 11 via a thread to limit the swing angle of the adjusting arm 11. By adjusting the height of the lifting column 10 and the tightness of the locking element 13, the height and angle of the high-efficiency cleaning unit 4 and the adaptive polishing component 5 can be adjusted to ensure that they can accurately act on different parts of the shoe edge.

[0026] like Figure 4 As shown, the high-efficiency cleaning unit 4 consists of a vacuum cleaner head 14, a high-pressure air nozzle 15, a scraper 16, and a dust collection box 17. The vacuum cleaner head 14 is fixedly installed at the end of the adjusting arm 11, and a scraper 16 is provided at its bottom, which is fixed to the lower end face of the vacuum cleaner head 14 by screws. The front end of the scraper 16 is arc-shaped, which can conform to the contour of the shoe edge and perform preliminary cleaning of the shoe edge surface. A high-pressure air nozzle 15 is provided on one side of the vacuum cleaner head 14. The high-pressure air nozzle 15 is connected to an external air source through a pipe, and blows away residual particles with high-pressure gas. The rear end of the vacuum cleaner head 14 is connected to the dust collection box 17 through a hose. The dust collection box 17 is fixed to one side of the base 1 and is used to collect dust and impurities cleaned from the shoe edge. In actual operation, the scraper 16 first physically scrapes away the shoe edge surface, then the high-pressure air nozzle 15 blows away residual particles, and finally the vacuum cleaner head 14 sucks the dust into the dust collection box 17, completing the cleaning process.

[0027] The adaptive polishing assembly 5 consists of a polishing head 18, a pressure sensor 19, an angle adjuster 20, and a telescopic rod 21. The polishing head 18 is movably connected to one end of the telescopic rod 21 via the angle adjuster 20. The angle adjuster 20 has an internal universal ball joint structure, the outer wall of which fits tightly against the inner cavity of the angle adjuster 20, allowing the polishing head 18 to freely adjust its angle within a certain range. A pressure sensor 19 is mounted on the side of the angle adjuster 20, and is connected to the control system via a signal line to detect the pressure applied by the polishing head 18. The other end of the telescopic rod 21 is fixed to the end of the adjusting arm 11, and contains an electric push rod. The output end of the electric push rod is fixedly connected to the bottom of the angle adjuster 20. By extending and retracting the electric push rod, the distance between the polishing head 18 and the shoe edge can be adjusted. Combined with the functions of the angle adjuster 20 and the pressure sensor 19, the angle and applied pressure of the polishing head 18 can be automatically adjusted according to the curvature of the shoe edge, avoiding uneven polishing or excessive wear.

[0028] In actual operation, the sports shoe to be processed is first fixed on the positioning fixture 8, and the position of the positioning fixture 8 is adjusted by the slide rail assembly 9 to adapt to the size of the shoe edge. Then, the drive motor 7 starts, and the rotating disk 6 drives the positioning fixture 8 to the cleaning station and the polishing station in sequence. At the cleaning station, the high-efficiency cleaning unit 4 performs preliminary cleaning of the shoe edge surface with the scraper 16, the high-pressure air nozzle 15 blows away residual particles, and the vacuum suction head 14 sucks the dust into the dust collection box 17. After cleaning is completed, the positioning fixture 8 moves with the rotating disk 6 to the polishing station, and the adaptive polishing assembly 5 starts working. Under the coordinated action of the angle adjuster 20 and the pressure sensor 19, the polishing head 18 automatically adjusts the angle and applied pressure according to the curvature of the shoe edge, and at the same time, the electric push rod in the telescopic rod 21 quickly responds to different processing requirements to complete the fine polishing of the shoe edge. Throughout the process, the flexible adjustment mechanism 3, through the cooperation of the lifting column 10 and the adjusting arm 11, ensures that the high-efficiency cleaning unit 4 and the adaptive polishing assembly 5 are always in the optimal working position.

[0029] The specific embodiments of this utility model have been described above, detailing the connection relationships, positional relationships, and mutual cooperation relationships of each component. The operating principle and operation process of the device are illustrated in conjunction with the accompanying drawings. Through the above technical solution, automation, intelligence, and efficiency in the processing of athletic shoe edges are achieved. To better enable those skilled in the art to fully understand and implement this utility model, the specific implementation principle of this utility model is further explained below in conjunction with a specific application scenario.

[0030] First, the athletic shoe to be processed is fixed onto the positioning clamp 8. The positioning clamp 8 is connected to the rotating disk 6 via a slide rail assembly 9. The slide rail assembly 9 allows the clamp to be finely adjusted along the groove direction to accommodate the processing needs of shoe edges of different sizes. Specifically, the operator adjusts the position of the positioning clamp 8 according to the actual width of the shoe edge and locks it with bolts to ensure that the clamp can stably fix the shoe body. This design allows the device to flexibly handle athletic shoes of different models or sizes, expanding its applicability.

[0031] Subsequently, the drive motor 7 starts, and its output shaft drives the rotating disk 6 to rotate, thereby transferring the positioning fixture 8 sequentially to the cleaning station and the polishing station. When the positioning fixture 8 enters the cleaning station, the high-efficiency cleaning unit 4 begins to work. The scraper 16 first physically scrapes the surface of the shoe edge, conforming to the contour of the shoe edge. The arc design of the scraper 16 can effectively remove firmly adhered glue residue or dust. Next, the high-pressure air nozzle 15 blows away residual particles with high-pressure gas provided by an external air source, further cleaning the surface of the shoe edge. Finally, the vacuum suction head 14 sucks the dust into the dust collection box 17 to complete the cleaning process. This multi-step cleaning method, which combines mechanical scraping, gas blowing, and vacuum suction, significantly improves the cleaning effect and avoids the impact of contaminant residue on subsequent processes.

[0032] After cleaning, the rotary table 6 continues to rotate, transferring the positioning fixture 8 to the polishing station. At this time, the adaptive polishing assembly 5 begins to work. The electric push rod inside the telescopic rod 21 extends or retracts according to the control system's instructions, adjusting the distance between the polishing head 18 and the shoe edge. Simultaneously, the universal ball joint structure inside the angle adjuster 20 allows the polishing head 18 to freely adjust its angle within a certain range to match the curvature changes of the shoe edge. The pressure sensor 19 detects the pressure applied by the polishing head 18 in real time and feeds the data back to the control system to ensure that the polishing force remains within a reasonable range. This collaborative working mode not only avoids excessive local wear but also ensures polishing uniformity, thereby improving the processing quality of the shoe edge.

[0033] Throughout the processing, the flexible adjustment mechanism 3 dynamically adjusts the height and angle of the high-efficiency cleaning unit 4 and the adaptive polishing assembly 5 through the cooperation of the lifting column 10 and the adjusting arm 11. The spring sleeved on the outer wall of the guide rod 12 acts as a vibration damper, while the locking element 13 limits the swing angle of the adjusting arm 11, ensuring that the cleaning and polishing units are always in the optimal working position. This design improves the stability of equipment operation and reduces processing errors caused by vibration.

[0034] In summary, this invention achieves automated processing of shoe edge finishing through the rotary transmission function of the multi-functional workstation module 2, solves the problem of poor cleaning effect in traditional equipment through the multi-stage cleaning process of the high-efficiency cleaning unit 4, and overcomes the defects of fixed grinding heads through the intelligent adjustment function of the adaptive grinding component 5. The synergistic effect of each component makes the entire device highly flexible and precise, providing a complete solution for shoe edge finishing in sports shoes.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
