Description

Technical Field

[0001] This utility model belongs to the field of shoemaking equipment technology, specifically a casual shoe welt pressing device. Background Technology

[0002] With the development of footwear manufacturing technology, the production of casual shoes demands increasingly higher levels of automation and pressing precision. This is especially true in the bonding process between the welt and the upper / sole, where the performance of the pressing equipment directly affects the product's appearance quality, structural strength, and production efficiency. Traditional casual shoe welt pressing relies heavily on manual operation or semi-automatic equipment, resulting in uneven pressing force, inaccurate positioning, and low production efficiency, making it difficult to meet the modern footwear industry's demand for high-quality, highly consistent products.

[0003] A search revealed a rubber shoe pressing device with publication number CN119791370B. This device relates to the field of rubber shoe manufacturing technology and includes a fixing frame, a fixing part (including left and right fixing devices), and a pressure applying part. The left and right fixing devices are joined together to form a fixed receiving space, and the upper and sole are pressed together after the glue injection port is sealed. The device uses a support part to maintain a gap between the protective plate and the upper, avoiding the problem of sole detachment caused by reduced contact area due to direct insertion into the protective plate. However, this technical solution mainly targets the glue injection pressing process of rubber shoes, and its structural design focuses on glue injection sealing and protective plate avoidance, without addressing the precise positioning and continuous molding pressing requirements of flexible materials such as casual shoe welts. Furthermore, the device lacks an adaptive adjustment mechanism for the bending and bonding path of the welt, making it unable to achieve uniform pressure on complex curved contours, easily causing the welt edges to curl or partially detach, making it unsuitable for the varied shoe shapes of casual shoes.

[0004] A search revealed a PU film fabric lamination device with publication number CN107175879B. This device is used to hot-press PU film onto the surface of fabric and includes a frame, heating rollers, silicone rollers, and a lamination transmission assembly. It uses hot pressing to enhance the adhesion between materials. Although this device has continuous feeding and hot-pressing lamination functions and is suitable for planar lamination of flexible materials, its lamination method is line-contact rolling, mainly used for lamination of planar or slightly curved materials. It lacks spatial adaptability for three-dimensional curved structures (such as shoe welts). When applied to lamination of casual shoe welts, since the welt needs to be wrapped around the edge of the shoe opening in a ring, this device cannot achieve stable pressure under multi-angle and variable curvature paths. Furthermore, it lacks a dedicated clamping and shaping mechanism, which can easily lead to displacement, wrinkling, or stretching deformation of the welt during the lamination process, affecting the final molding quality.

[0005] The aforementioned problems indicate that existing pressing equipment has significant limitations when applied to pressing welts in casual shoes: on the one hand, pressing equipment for rubber shoes focuses on glue injection and sealing, lacking precise control over the welt's shape; on the other hand, pressing equipment for fabric composites is suitable for planar hot pressing and is difficult to adapt to the complex pressing paths of the shoe's three-dimensional structure. Neither of these methods solves the key technical challenges required for pressing welts in casual shoes, such as precise positioning, curved surface bonding, uniform pressure distribution, and automated continuous operation.

[0006] Therefore, this utility model provides a casual shoe welt pressing equipment, which aims to overcome the problems of poor adaptability to welt pressing, low molding accuracy and insufficient automation in the existing technology, and realize efficient, stable and high-quality pressing of welts of different shoe types, so as to meet the needs of modern shoe production lines for intelligent and flexible equipment. Utility Model Content

[0007] This utility model relates to a casual shoe welt pressing device, including a support base, a positioning component, a curved surface fitting component, and a pressure applying component. The positioning component is mounted on the top of the support base, the curved surface fitting component is located on one side of the positioning component, and the pressure applying component is positioned above the curved surface fitting component. The positioning component is used to fix the shoe body to be processed, ensuring its stability during the pressing process; the curved surface fitting component achieves adaptive adjustment of the welt path for different shoe shapes through a multi-degree-of-freedom adjustment mechanism; the pressure applying component completes the uniform pressing of the welt through a balanced force transmission mechanism.

[0008] The positioning assembly includes a fixing frame, a clamping plate, an adjusting screw, and a limiting block. The bottom of the fixing frame is fixedly connected to the top surface of the support base by bolts. The clamping plates are symmetrically installed on the inner side of the fixing frame, and the outer side of the clamping plates is threadedly engaged with the adjusting screw. One end of the adjusting screw passes through the fixing frame and is controlled to rotate by a handwheel, while the other end is connected to the outer wall of the clamping plate through a bearing. The inner surface of the clamping plate is provided with a flexible pad to protect the surface of the shoe from damage. The top of the fixing frame is also provided with a limiting block, which is slidably connected to the fixing frame through a sliding groove structure and fixed in position by a locking screw to limit the axial movement of the shoe.

[0009] The curved surface adaptation component includes a multi-segment pressing head, a guide arm, and a drive unit. The multi-segment pressing head consists of multiple arc-shaped pressing plates connected by hinges. The two ends of the hinges are embedded in the sidewalls of the arc-shaped pressing plates and fixed by pins. A spring is provided at the outer end of the pin to provide fine-tuning force. A guide arm is located at the bottom of the multi-segment pressing head. One end of the guide arm is connected to the multi-segment pressing head via a ball joint, and the other end slides against the side of the support base via a slide rail. The drive unit includes a servo motor, a synchronous belt, and a transmission gear set. The servo motor is fixedly installed inside the support base, and its output shaft meshes with the transmission gear set via a coupling. The output end of the transmission gear set is connected to the slide rail of the guide arm via the synchronous belt, driving the guide arm to move along the slide rail, thereby achieving path adjustment of the multi-segment pressing head.

[0010] The pressure application assembly includes a cylinder, a pressure plate, pressure sensors, and an elastic compensation layer. The bottom of the cylinder is bolted to the top of the support base, and the top of the cylinder's piston rod is welded to the center of the pressure plate. The bottom of the pressure plate has an elastic compensation layer made of highly elastic silicone material, used to absorb pressure fluctuations in uneven areas during the pressing process. Pressure sensors are installed at the four corners of the pressure plate, and these sensors are connected to an external control system via signal lines to monitor the pressure distribution in different areas of the pressure plate in real time. When the pressure distribution is uneven, the cylinder adjusts the extension and retraction length of the piston rod through feedback signals to make the force on the pressure plate more even.

[0011] This invention solves the problem of unstable shoe fixing in traditional equipment through the design of positioning components. The clamping plate achieves precise clamping of the shoe body through adjusting the screw, the flexible padding layer avoids damage to the shoe surface from hard contact, and the limiting block further enhances the axial stability of the shoe body. This design ensures that the shoe body will not shift or tilt during the pressing process, providing a reliable foundation for subsequent processes.

[0012] This invention achieves adaptive adjustment to complex three-dimensional curved surfaces through a curved surface adaptation component. The arc-shaped pressure plates of the multi-segment pressing head are connected by hinges, enabling automatic angle adjustment according to the shoe's contour. The fine-tuning force provided by the spring ensures that the pressing head always adheres to the shoe surface. The cooperation between the guide arm and the slide rail allows the pressing head to move flexibly in the horizontal direction, while the servo motor drives the guide arm through a synchronous belt and transmission gear set, achieving precise control of the pressing path. This design effectively solves the problem of existing equipment being unable to adapt to the curved path of the welt, avoiding the phenomenon of welt edges lifting or localized delamination.

[0013] This invention achieves uniform pressing of the welt using a pressure application component. A cylinder acts as the power source, pushing the pressure plate downwards via a piston rod. An elastic compensation layer buffers the pressure during the pressing process, reducing pressure concentration caused by unevenness on the shoe surface. Pressure sensors monitor the pressure distribution in different areas of the pressure plate in real time and feed the data back to the control system. The control system adjusts the cylinder's output force based on the feedback information to ensure uniform pressing force distribution. This design significantly improves the quality and consistency of the welt pressing.

[0014] This invention combines a positioning component, a curved surface adaptation component, and a pressure application component. Through the coordinated operation of a multi-degree-of-freedom adjustment mechanism and a balanced force transmission mechanism, it solves the problems of insufficient positioning accuracy, poor curved surface adaptation capability, and uneven pressure distribution in traditional pressing equipment during welt pressing. This equipment is suitable for welt pressing of various shoe types, has a high degree of automation and production efficiency, and simultaneously improves the appearance quality and structural strength of the products, meeting the demands of the modern footwear industry for intelligent and flexible equipment.

[0020] 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.

[0021] Specific implementation examples are given below.

[0022] This utility model relates to a pressing device for the welt of casual shoes, the structure of which is as follows: Figure 1 As shown, the device includes a support base 1, a positioning component 2, a curved surface adaptation component 3, and a pressure application component 4. The support base 1 serves as the foundation for the entire device, with the positioning component 2 mounted on its top for securing the shoe body to be processed. The curved surface adaptation component 3 is located on one side of the positioning component 2, and this component uses a multi-degree-of-freedom adjustment mechanism to adaptively adjust the path of the welt for different shoe shapes. The pressure application component 4 is positioned above the curved surface adaptation component 3 to uniformly press the welt. The specific structure, connection relationships, and working principles of each component are described in detail below with reference to the accompanying drawings.

[0023] The specific structure of positioning component 2 is as follows: Figure 2 As shown, the system includes a fixing frame 5, a clamping plate 6, an adjusting screw 7, and a limiting block 8. The bottom of the fixing frame 5 is bolted to the top surface of the support base 1. The clamping plates 6 are symmetrically installed on the inner side of the fixing frame 5, and their outer sides are threaded into the adjusting screw 7. One end of the adjusting screw 7 passes through the fixing frame 5 and is controlled to rotate via a handwheel; the other end is connected to the outer wall of the clamping plate 6 via a bearing. By rotating the handwheel, the adjusting screw 7 drives the clamping plate 6 to slide along the inner side of the fixing frame 5, thereby clamping or releasing the shoe body. The inner surface of the clamping plate 6 is provided with a flexible pad made of rubber material to prevent damage to the shoe surface from hard contact. A limiting block 8 is located at the top of the fixing frame 5. The limiting block 8 is slidably connected to the fixing frame 5 via a sliding groove structure and is fixed in position by a locking screw. The limiting block 8 can be adjusted in position according to the height of the shoe body to limit axial movement and ensure stability during the pressing process.

[0024] The specific structure of surface adapter component 3 is as follows: Figure 3 As shown, the device includes a multi-segment pressing head 9, a guide arm 10, and a drive unit. The multi-segment pressing head 9 consists of multiple arc-shaped pressing plates 16, which are connected by hinges 17. The two ends of the hinges 17 are embedded in the side walls of the arc-shaped pressing plates 16 and fixed by pins. A spring 18 is provided at the outer end of the pin. The spring 18 provides fine-tuning force, allowing the arc-shaped pressing plates 16 to automatically adjust their angle within a certain range, thereby conforming to the three-dimensional curved surface of the shoe body. The bottom of the multi-segment pressing head 9 is provided with a guide arm 10. One end of the guide arm 10 is connected to the multi-segment pressing head 9 through a ball joint, and the other end slides against the side of the support base 1 through a slide rail. The drive unit includes a servo motor 11, a synchronous belt, and a transmission gear set. The servo motor 11 is fixedly installed inside the support base 1, and its output shaft meshes with the transmission gear set through a coupling. The output end of the transmission gear set is connected to the slide rail of the guide arm 10 through the synchronous belt. The servo motor 11 drives the guide arm 10 to move along the slide rail via a synchronous belt and a transmission gear set, thereby driving the multi-segment pressing head 9 to make precise adjustments along the path of the shoe body strip.

[0025] The specific structure of pressure application component 4 is as follows: Figure 4 As shown, the system includes a cylinder 12, a pressure plate 13, an elastic compensation layer 14, and pressure sensors 15. The bottom of the cylinder 12 is bolted to the top of the support base 1, and the top of the piston rod of the cylinder 12 is welded to the center of the pressure plate 13. The bottom of the pressure plate 13 is provided with an elastic compensation layer 14, which is made of highly elastic silicone material and can absorb pressure fluctuations caused by unevenness of the shoe surface during the pressing process. Pressure sensors 15 are installed at the four corners of the pressure plate 13, and the pressure sensors 15 are connected to an external control system via signal lines. When the cylinder 12 pushes the pressure plate 13 downward to apply pressure, the pressure sensors 15 monitor the pressure distribution in each area of ​​the pressure plate 13 in real time and feed the data back to the control system. The control system adjusts the output force of the cylinder 12 according to the feedback information to make the force on the pressure plate 13 more balanced.

[0026] The curved pressure plate 16 is connected by hinges 17. Both ends of the hinges 17 are embedded in the sidewalls of the curved pressure plate 16 and fixed by pins. A spring 18 is provided at the outer end of the pin. The elasticity of the spring 18 allows the curved pressure plate 16 to automatically adjust its angle within a certain range, thus conforming to the complex curves of the shoe body. The surface of the curved pressure plate 16 is polished to reduce friction and improve durability. The bottom of the multi-segment pressing head 9 is connected to the guide arm 10 via a ball joint. The ball joint allows the multi-segment pressing head 9 to flexibly adjust its angle in multiple directions to adapt to the welt paths of different shoe types. The slide rail of the guide arm 10 slides in engagement with the side of the support base 1. The surface of the slide rail is coated with a lubricating layer to reduce frictional resistance and improve operational smoothness.

[0027] In actual operation, the shoe body to be processed is first placed between the clamping plates 6 of the positioning component 2. By rotating the handwheel of the adjusting screw 7, the clamping plates 6 are slid along the inner side of the fixing frame 5 until the flexible padding layer of the clamping plates 6 is tightly attached to the surface of the shoe body. Then, the position of the limiting block 8 is adjusted so that it slides along the slide groove structure to a suitable height and is fixed by the locking screw to restrict the axial movement of the shoe body. After the shoe body is fixed, the servo motor 11 is started. The servo motor 11 drives the guide arm 10 to move along the slide rail through the transmission gear set and the synchronous belt, thereby driving the multi-segment pressing head 9 to make precise adjustments along the path of the shoe body strip. The arc-shaped pressing plate 16 of the multi-segment pressing head 9 can automatically adjust the angle according to the contour of the shoe body through the cooperation of the hinge 17 and the spring 18 to ensure that the pressing head is always attached to the surface of the shoe body.

[0028] After the multi-segment pressing head 9 is adjusted into place, the cylinder 12 is activated, pushing the pressure plate 13 downwards to apply pressure. The elastic compensation layer 14 at the bottom of the pressure plate 13 acts as a buffer during the pressing process, reducing pressure concentration caused by unevenness on the shoe surface. Simultaneously, pressure sensors 15 at the four corners of the pressure plate 13 monitor the pressure distribution in each area in real time and feed the data back to the control system. The control system adjusts the output force of the cylinder 12 based on the feedback information, making the force on the pressure plate 13 more even, thereby achieving uniform pressing of the welt.

[0029] This invention solves the problem of unstable shoe body fixation in traditional equipment through the design of the positioning component 2. The clamping plate 6 achieves precise clamping of the shoe body through the adjustment screw 7, the flexible padding layer avoids damage to the shoe body surface from hard contact, and the limiting block 8 further enhances the axial stability of the shoe body. The curved surface adaptation component 3 achieves adaptive adjustment to complex three-dimensional curved surfaces through the cooperation of the arc-shaped pressure plate 16 and spring 18 of the multi-segment pressing head 9. The cooperation between the guide arm 10 and the slide rail allows the pressing head to move flexibly in the horizontal direction, while the servo motor 11 drives the guide arm 10 through the synchronous belt and transmission gear set to achieve precise control of the pressing path. The pressure application component 4 achieves uniform pressing of the welt through the coordinated work of the cylinder 12, pressure plate 13, elastic compensation layer 14 and pressure sensor 15, which significantly improves the quality and consistency of the welt pressing. The structural design of the above components and their mutual cooperation ensure that this invention can be applied to the welt pressing of various shoe types, has a high degree of automation and production efficiency, and meets the needs of the modern shoe manufacturing industry for intelligent and flexible equipment. To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.

[0030] First, the shoe body to be processed is placed between the clamping plates 6 of the positioning assembly 2. By rotating the handwheel of the adjusting screw 7, the clamping plates 6 are slid along the inner side of the fixing frame 5 until the flexible padding layer of the clamping plates 6 is tightly attached to the surface of the shoe body. During this process, the threaded engagement between the adjusting screw 7 and the clamping plates 6 achieves precise control of the clamping force, while the flexible padding layer avoids damage to the surface of the shoe body from hard contact. Subsequently, the position of the limiting block 8 is adjusted so that it slides along the slide groove structure to a suitable height and is fixed by the locking screw. The setting of the limiting block 8 effectively restricts the axial movement of the shoe body, ensuring that the shoe body remains stable throughout the pressing process. This series of operations provides a reliable positioning basis for subsequent processes.

[0031] After the shoe body is fixed, the servo motor 11 is activated. The servo motor 11 drives the guide arm 10 to move along the slide rail via a transmission gear set and a synchronous belt, thereby causing the multi-segment pressing head 9 to precisely adjust along the shoe body's welt path. The multi-segment pressing head 9 consists of multiple arc-shaped pressing plates 16, which are connected by hinges 17. A spring 18 at the outer end of the pin provides fine-tuning force, allowing the arc-shaped pressing plates 16 to automatically adjust their angles according to the shoe body contour, thus conforming to the three-dimensional curved surface of the shoe body. The guide arm 10 is connected to the multi-segment pressing head 9 via a ball joint, allowing the multi-segment pressing head 9 to flexibly adjust its angle in multiple directions to adapt to the welt paths of different shoe types. The lubricating coating on the slide rail surface reduces frictional resistance and improves operational smoothness. This design ensures that the multi-segment pressing head 9 can accurately conform to the shoe body surface, solving the problem that existing equipment struggles to adapt to complex curved surfaces.

[0032] After the multi-segment pressing head 9 is adjusted into position, cylinder 12 is activated, pushing the pressing plate 13 downwards to apply pressure. The elastic compensation layer 14 at the bottom of the pressing plate 13 acts as a buffer during the pressing process, absorbing pressure fluctuations caused by unevenness on the shoe surface and preventing excessive local pressure from causing deformation or delamination of the welt. Simultaneously, pressure sensors 15 installed at the four corners of the pressing plate 13 monitor the pressure distribution in each area in real time and feed the data back to the external control system. The control system adjusts the output force of cylinder 12 based on the feedback information, making the force on the pressing plate 13 more even, thereby achieving uniform pressing of the welt. This closed-loop control mechanism significantly improves the uniformity of the pressing force distribution, ensuring the quality and consistency of the welt pressing.

[0033] In this invention, the clamping plate 6 achieves precise clamping of the shoe body through the adjusting screw 7, the flexible padding layer avoids damage to the shoe body surface from hard contact, and the limiting block 8 further enhances the axial stability of the shoe body. This design fundamentally solves the problem of unstable shoe body fixation in traditional equipment, ensuring that the shoe body will not shift or tilt during the pressing process. The arc-shaped pressing plate 16 of the multi-segment pressing head 9 achieves adaptive adjustment to complex three-dimensional curved surfaces through the cooperation of hinge 17 and spring 18. The cooperation of guide arm 10 and slide rail allows the pressing head to move flexibly in the horizontal direction, while the servo motor 11 drives the guide arm 10 through synchronous belt and transmission gear set, realizing precise control of the pressing path. This multi-degree-of-freedom adjustment mechanism effectively solves the problem that existing equipment is difficult to adapt to the bending path of the welt, avoiding the phenomenon of welt edge lifting or local delamination. The pressure application component 4 achieves uniform pressing of the welt through the coordinated work of cylinder 12, pressure plate 13, elastic compensation layer 14 and pressure sensor 15, significantly improving the quality and consistency of welt pressing.

[0034] The structural design of the aforementioned components and their interrelationships ensure that this invention is applicable to the pressing of welts for various shoe types, possessing a high degree of automation and production efficiency, thus meeting the demands of the modern footwear industry for intelligent and flexible equipment.

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.
