Technical Field

[0001] The present invention relates to the technical field of sports shoe production, in particular to a sports shoe production device free of glue coating and a preparation method thereof. Background Art

[0002] Athletic shoes are footwear designed specifically for sports, offering cushioning, support, and slip resistance, making them suitable for a variety of activities, including running, basketball, and fitness. They utilize breathable mesh, lightweight midsoles (such as EVA and air cushions), and durable rubber outsoles for enhanced comfort and durability. Modern athletic shoes, incorporating innovative technologies like Boost and Air Max, combine performance with style, becoming an everyday essential. Professional athletic shoes can effectively reduce sports injuries and enhance athletic performance, but their production and processing requires extensive equipment.

[0003] Athletic shoe production equipment is a core component of the footwear industry, encompassing key processes such as cutting, sewing, molding, and shaping. The cutting process utilizes hydraulic or laser cutting machines to precisely cut leather, mesh, and other upper materials; the sewing process relies on high-precision sewing machines and computerized pattern machines to complete complex stitching. Sole production relies on equipment such as EVA injection molding machines and rubber vulcanizers to ensure midsole cushioning and outsole wear resistance. The molding stage uses cold gluing, hot pressing, or injection molding processes, utilizing molding machines, sole-pressing machines, and other equipment to achieve a secure bond between the upper and sole. Modern production lines have introduced automated robotic arms, 3D printing, and intelligent control systems, significantly improving production efficiency and product consistency while reducing reliance on manual labor and driving the development of intelligent and refined athletic shoe manufacturing.

[0015] A method for preparing sports shoes without glue coating is as follows: S1. The unvulcanized rubber sheet material is loaded into the mounting clamp slot through the unwinding roller, passed through the bottom of the first limiting roller, the top of the regulating roller, and between the heating roller and the squeezing roller in sequence, and finally wound around the bottom of the second limiting roller and fixed to the winding roller. The other unwinding roller is loaded with a PE film and laid along the same path so that the PE film contacts the bottom of the rubber material. The spring 1 is activated to push the squeezing roller to apply pressure, and the heating roller heats the material to bond the PE film to the rubber. The winding roller pulls the material to move, and the fan cools and solidifies the bonding layer. S2: Start hydraulic cylinder 1 to push the moving table, driving the sliding column and the mounting frame to press against the raw material.

In the present invention, the unwinding roller group and the limiting roller constitute a precise feeding system to ensure the alignment accuracy of the rubber sheet and the PE film. The heating roller and the elastic pressure module form a dynamic hot pressing system, in which the spring-driven extrusion roller can automatically adjust the pressure as the material thickness changes, and cooperate with the constant temperature heating roller to achieve molecular-level bonding. The winding roller and the cooling system form a closed-loop processing unit, and forced cooling and shaping are immediately carried out after the completion of hot pressing. The various structural units achieve coordinated matching of speed and temperature through a linkage control system. This organic coordination not only ensures the consistency of the composite quality, but also realizes the automation of the entire process from feeding, composite to winding, effectively solving the inherent defects of the traditional bonding process.

[0016] 2. In the present invention, the accuracy and stability of raw material cutting are significantly improved through the coordinated cooperation of hydraulic drive and elastic buffer system. Hydraulic cylinder 1 provides stable propulsion power, and the buffer system composed of spring 2 can adaptively compensate for material thickness fluctuations, ensuring that the cutting tool always contacts the raw material with constant pressure. This dynamic pressure adjustment mechanism effectively avoids the problems of material deformation or tool damage caused by traditional rigid cutting. At the same time, the guide structure of the mounting frame ensures the straightness of the cutting path, making the incision smoother. The overall design realizes the perfect combination of flexible pressurization and rigid guidance in the cutting process, which not only improves the processing quality but also extends the service life of the tool.

[0017] 3. In the present invention, the sliding rod is driven to move by a bidirectional threaded rod, and the inclined groove guide structure is used to enable the positioning block to be synchronously and accurately displaced to complete the clamping and loosening of the lower mold. This innovative transmission mechanism not only ensures the firm fixation of the mold during the hot pressing process, but also greatly simplifies the mold replacement process. At the same time, the coordinated cooperation of the robotic arm and the hydraulic system realizes continuous operation from material cutting to hot pressing. The entire system ensures stability through the mechanical self-locking principle, and the modular design improves adaptability, providing an efficient and flexible solution for the production of products of different specifications, significantly improving production efficiency and process reliability.

DETAILED DESCRIPTION

[0020] The following is combined with Figure 1 -Attached Figure 8 , the present invention is described in further detail.

[0021] Reference Figure 1 , Figure 4 and Figure 5 The present invention provides a glue-free sports shoe production equipment, including a base 1, which provides a stable support platform for the entire equipment. A bonding mechanism 2 is installed on the top of the base 1, which realizes the automatic bonding function of materials without manual gluing. A support seat 3 is fixedly connected to one side of the base 1, and the support seat 3 serves as a mounting base for cutting and driving components. A cutting mechanism 4 is installed on the top of the support seat 3, and the cutting mechanism 4 can accurately cut the bonded composite material. A driving mechanism 5 is installed on one side of the support seat 3, and the driving mechanism 5 provides stable material conveying power. An extension platform 6 is fixedly connected to one side of the support seat 3, and the extension platform 6 expands the working area of ​​the equipment. A mounting mechanism 7 is provided on one side of the extension platform 6, and the mounting mechanism 7 facilitates rapid replacement of molds. A pressing mechanism 8 is fixedly connected to the top of the extension platform 6, and the pressing mechanism 8 completes the final hot pressing molding process. Specifically, the base 1 provides an installation basis for various functional mechanisms, the bonding mechanism 2 realizes automatic bonding of materials through hot pressing, the support seat 3 carries the cutting mechanism 4 and the driving mechanism 5, wherein the cutting mechanism 4 accurately cuts the bonded material, the driving mechanism 5 ensures stable material transportation, the extension table 6 expands the processing area, and the installation mechanism 7 thereon realizes rapid replacement of the mold, and the pressing mechanism 8 performs the final hot pressing and shaping of the molding material. The various mechanisms work together to realize the automated production of sports shoe components.

[0022] The bonding mechanism 2 includes a plurality of fixed plates 21, which constitute the support frame of the heating system. The adjacent sides of the plurality of fixed plates 21 are rotatably connected to heating rollers 22, which activate the surface of the rubber sheet by heat conduction. The inner wall of the fixed plate 21 is slidably connected to a sliding block 23, and the adjacent sides of the two sliding blocks 23 are rotatably connected to an extrusion roller 24. The extrusion roller 24 realizes the physical combination of the PE film and the rubber sheet under the action of pressure. The bottom of the sliding block 23 is fixedly connected to a connecting column 25, which transmits the spring force to the extrusion system. The outside of the connecting column 25 is slidably connected to a shell 26, which provides a closed working space for the spring. The inner wall of the shell 26 is fixedly connected to a spring 27, which provides a continuous and stable pressing force. Fans 212 are installed on both sides of the top of the base 1. The fan 212 accelerates the cooling and shaping of the bonding interface. A tension component 28 is installed on the top of the base 1 to ensure the flatness of the material during processing. Specifically, the heating roller 22 is powered on and heated to a set temperature, activating the surface of the passing rubber sheet; at the same time, the spring 1 27 pushes the connecting column 25 through the shell 26, so that the sliding block 23 drives the squeezing roller 24 to move toward the heating roller 22, applying constant pressure to the rubber sheet and the PE film to achieve physical bonding, the tension component 28 adjusts the material tension to keep it flat, and the fan 212 blows air to cool the bonding part to quickly shape the bonding surface. The entire process achieves glue-free hot pressing bonding, ensuring that the materials are firmly bonded and efficient.

[0023] Restriction rollers 29 are installed on both sides of the top of the base 1 to guide the material to maintain the correct direction. Two mounting clamps 210 are fixedly connected to one side of the top of the base 1. The mounting clamps 210 realize the rapid loading and unloading of the raw material roll. The inner wall of the mounting clamp 210 is installed with a discharge roller 211. The discharge roller 211 ensures continuous and stable material transportation. The other end of the spring 27 is fixedly connected to one side of the connecting column 25. This connection method ensures uniform pressure distribution. Specifically, after the raw material on the discharge roller 211 is fixed by the mounting clamp 210, it is guided into the processing area through the limiting roller 29. The spring 27 applies balanced pressure to the extrusion system through the connecting column 25 to ensure smooth material transportation. The limiting roller 29 accurately controls the direction of the raw material. The mounting clamp 210 facilitates the rapid replacement of the material roll to realize continuous automated production. The entire feeding system works together to provide a stable material supply for subsequent processing.

[0024] The tension assembly 28 includes two adjustment frames 281, which constitute the guide track of the tension system. The bottom of the adjustment frame 281 is fixedly connected to the top of the base 1. A control block 282 is slidably connected to the groove of the adjustment frame 281. The control block 282 realizes the precise positioning of the tension roller. The bottom of the control block 282 is fixedly connected to the cylinder 283. The cylinder 283 provides programmable tension control. The bottom of the cylinder 283 is fixedly connected to the top of the base 1. The adjacent sides of the two control blocks 282 are rotatably connected to the adjustment roller 284. The adjustment roller 284 dynamically adjusts the material tension. Specifically, the cylinder 283 drives the control block 282 to slide along the groove of the adjustment frame 281, driving the adjustment roller 284 to rise and fall. When the material tension changes, the cylinder 283 automatically adjusts the position of the control block 282 according to the preset program, so that the adjustment roller 284 applies appropriate tension to the material. The two adjustment rollers 284 work together to ensure that the material always remains flat during the transportation process. This component achieves precise tension control through pneumatic transmission, effectively avoiding wrinkling or stretching deformation of the material, and providing stable conditions for subsequent processing.

[0025] refer to Figure 2 , Figure 3 and Figure 6 The cutting mechanism 4 includes a fixed frame 41, which ensures the structural rigidity of the cutting system. One side of the fixed frame 41 is fixedly connected to one side of the support base 3. The top of the fixed frame 41 is fixedly connected to a hydraulic cylinder 42. The hydraulic cylinder 42 provides a stable downward force. The driving end of the hydraulic cylinder 42 is fixedly connected to a moving platform 43. The moving platform 43 realizes the linear motion of the cutting head. A cutting tool 44 is installed at the bottom of the moving platform 43. The cutting tool 44 adopts high-frequency vibration cutting technology. The inner walls on both sides of the moving platform 43 are slidably connected with sliding columns 45. The sliding columns 45 realize the guide of the buffer mechanism. To function, the outer sleeve of the sliding column 45 is provided with a spring 46, which absorbs the cutting impact force. The bottom of the sliding column 45 is fixedly connected to a mounting frame 47, which integrates the pressing and guiding functions. The inner wall of the mounting frame 47 is rotatably connected to a rotating roller 48, which reduces the resistance to material movement. The top of the sliding column 45 is fixedly connected to a limiting block 49, which prevents the component from detaching. One end of the spring 46 is fixedly connected to one side of the moving platform 43, and the other end of the spring 46 is fixedly connected to one side of the mounting frame 47. This layout forms a two-way buffer system. Specifically, hydraulic cylinder 1 42 drives the movable platform 43 to move vertically downward, driving the cutting tool 44 and the mounting frame 47 to move synchronously. The mounting frame 47 contacts the material first, and the rotating roller 48 assists in positioning the material. At the same time, the spring 2 46 is compressed and buffered. As the hydraulic cylinder 1 42 continues to apply pressure, the cutting tool 44 performs high-frequency vibration cutting. During the cutting process, the spring 2 46 absorbs vibration through a two-way buffer system, and the limit block 49 ensures the safety of the stroke. After the cutting is completed, the hydraulic cylinder 1 42 returns and the spring 2 46 resets. This system achieves stable cutting while protecting the integrity of the material edge.

[0026] The driving mechanism 5 includes a motor 51. The motor 51 adopts servo control to ensure the winding accuracy. One side of the motor 51 is fixedly connected to one side of the support base 3. The driving end of the motor 51 is fixedly connected to the winding roller 52. The surface of the winding roller 52 has an anti-slip texture design. The top of the support base 3 is installed with a limiting roller 53. The limiting roller 53 ensures the accuracy of the winding angle. Specifically, servo motor 1 51 precisely drives the winding roller 52 to rotate, and the anti-slip texture on the surface ensures that the material does not slip. Limit roller 2 53 accurately guides the material to be wound around the winding roller 52 at a constant angle to achieve neat winding. The servo control system of motor 1 51 can adjust the speed and tension according to the process requirements to ensure a stable and efficient winding process, providing a flat material roll for subsequent processes.

[0027] refer to Figure 1 , Figure 7 and Figure 8 The top of the sliding sleeve 75 is fixedly connected to the bottom of the extension platform 6, and the inner wall of the plurality of positioning blocks 76 is coupled to the lower mold 77. The lower mold 77 can quickly replace different shoe-shaped molds. The top of the threaded block 73 is slidably connected to the bottom of the extension platform 6, and the outer side of the sliding rod 74 is slidably connected to the inner wall of the extension platform 6. A mechanical arm 9 is provided on one side of the base 1, and the mechanical arm 9 is equipped with a vacuum suction cup device. Specifically, motor 2 71 drives the bidirectional threaded rod 72 to rotate, driving the threaded blocks 73 on both sides to move toward each other synchronously, and the sliding rod 74 pushes the sliding sleeve 75 to move along the inclined groove of the extension platform 6, so that the positioning block 76 can accurately clamp the lower mold 77 through the conical positioning surface. This mechanism realizes rapid mold replacement, and the robotic arm 9 cooperates to complete the mold loading and unloading, ensuring rapid switching of different shoe types. The entire process has a high degree of automation and stable and reliable clamping.

[0028] The pressing mechanism 8 includes a driving platform 81, which is made of high-strength cast iron. The bottom of the driving platform 81 is fixedly connected to the top of the extension platform 6. The top of the driving platform 81 is fixedly connected to a second hydraulic cylinder 82, which has a pressure-maintaining function. The driving end of the second hydraulic cylinder 82 is fixedly connected to an upper mold 83, and the upper mold 83 has a built-in heating pipeline. Specifically, hydraulic cylinder 2 82 drives the upper mold 83 downward to cooperate with the lower mold 77 to complete hot pressing molding. The upper mold 83 maintains a constant temperature through a built-in heating pipeline to ensure that the material is fully softened; the pressure maintenance function of hydraulic cylinder 2 82 makes the molding process stable and controllable, and the high-strength structure of the drive platform 81 provides solid support for pressing, realizing precise sole molding operations and ensuring product size consistency.

[0029] A method for preparing sports shoes without glue coating is as follows: S1. The unvulcanized rubber sheet material is loaded into the slot of the mounting clamp 210 through the unwinding roller 211. The material passes through the bottom of the limiting roller 29, the top of the adjusting roller 284, and between the heating roller 22 and the squeezing roller 24. Finally, it is wound around the bottom of the limiting roller 53 and fixed to the winding roller 52. The other unwinding roller 211 is loaded with a PE film and laid along the same path so that the PE film contacts the bottom of the rubber material. The spring 27 is activated to push the squeezing roller 24 to apply pressure. The heating roller 22 is heated to bond the PE film to the rubber. The winding roller 52 pulls the material to move. The fan 212 cools and solidifies the adhesive layer. S2. Start hydraulic cylinder 1 42 to push movable platform 43, driving sliding column 45 and mounting frame 47 to press against the raw material. Hydraulic cylinder 1 42 continues to apply pressure, and spring 2 46 deforms under pressure to provide a reverse force, ensuring that mounting frame 47 can stably press the material. Moving platform 43 continues to move forward, driving cutting tool 44 to complete precise cutting. S3, the robot arm 9 transfers the cut material to the lower mold 77, aligns it with the EVA small foam bottom, and starts the hydraulic cylinder 82 to drive the upper mold 83 downward to perform hot pressing molding operation; S4: Start the second motor 71 to rotate the bidirectional threaded rod 72, drive the threaded block 73 and the sliding rod 74 to move, and the sliding sleeve 75 slides along the inclined groove to push the positioning block 76 to move, release or lock the fixation of the lower mold 77, and reset after completing the mold replacement to prepare for the next round of molding operation. Working principle: When the equipment needs to be used, the vulcanized rubber sheet material to be processed is placed on the card slot of the mounting clamp 210 through one of the discharge rollers 211. At this time, the material passes through the bottom of the two limiting rollers 29, passes through the top of the adjusting roller 284, and finally passes between the heating roller 22 and the squeezing roller 24. Finally, it goes around to the bottom of the limiting roller 2 53 and the outside of the winding roller 52, so that the material can be controlled to be wound by starting the motor 1 51, and then the PE film is placed through another discharge roller 211. The above operation is repeated to make the PE film contact with the bottom of the raw material. Under the contact between the raw material and the PE film, the elastic potential energy released by the spring 1 27 pushes the connecting column 25, so that the connecting column 25 drives the sliding block 23 to make the squeezing roller 24 squeeze the raw material and the PE film, and cooperates with the heating roller 22 to heat the raw material so that the PE film and the raw material are bonded. The motor 1 51 is started to drive the bonding and subsequent materials to move, and the fan 212 is started for cooling to complete the bonding operation. After bonding, the hydraulic cylinder 42 is started, and the movable platform 43 is driven to move under the activation of the hydraulic cylinder 42. At this time, the movement of the movable platform 43 moves the sliding column 45, so that the sliding column 45 drives the installation frame 47 to move, and finally the installation frame 47 moves to press against the raw material. At this time, the hydraulic cylinder 42 is continuously started, so that the installation frame 47 pushes the sliding column 45 to slide on the inner wall of the movable platform 43. At this time, the movement of the sliding column 45 causes the spring 2 46 to be squeezed and deformed. The deformation of the spring 2 46 provides a force to push the installation frame 47 tightly against the raw material, and finally, the cutting tool 44 is driven to cut the raw material under the movement of the movable platform 43, thereby improving the cutting stability. After cutting, the cut material is placed inside the lower mold 77 by starting the robotic arm 9 and hot-pressed together with the EVA small foam bottom. At this time, the upper mold 83 is driven to move by starting the hydraulic cylinder 2 82, so that the upper mold 83 can perform hot-pressing operation. Finally, when the lower mold 77 needs to be disassembled and replaced, the bidirectional threaded rod 72 is driven to rotate by starting the motor 2 71. At this time, the rotation of the bidirectional threaded rod 72 will drive the threaded block 73 to move, and the movement of the threaded block 73 can drive the sliding rod 74 to move. At this time, the movement of the sliding rod 74 will cause the sliding sleeve 75 to move, and the top of the extension platform 6 is provided with an inclined groove, which will cause the positioning block 76 to slide on the inner wall of the inclined groove, so that the sliding sleeve 75 will slide on the outside of the sliding rod 74, causing the position of the positioning block 76 to change, thereby clamping and fixing the lower mold 77 and realizing the replacement and adjustment of the lower mold 77.
