Description

Technical Field

[0001] This utility model relates to the field of shoe manufacturing technology, and more specifically, to a shoe manufacturing positioning mechanism. Background Technology

[0002] In modern footwear manufacturing, production lines need to handle shoes of various sizes and styles, which poses a significant challenge to the positioning and clamping processes. Currently, most clamping devices used by footwear manufacturers are rigidly designed and have fixed structures, typically only effective for a specific model or size range of shoes.

[0003] In actual production, when different shoe models need to be changed, operators often need to spend a lot of time adjusting or replacing the clamps, and may even need to stop the machine to reset parameters, which seriously affects production efficiency and the continuity of the production line. In addition, inappropriate clamping force may also cause deformation of the shoe upper or damage to the sole, increasing the defect rate of the product, resulting in material waste and increased costs.

[0004] In a footwear market characterized by strong seasonality and rapid style updates, manufacturers need to be able to respond quickly to market demands, making the versatility and flexibility of production equipment a key competitive advantage. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] In view of the problems existing in the prior art, this utility model provides a shoe production positioning mechanism to solve the technical problems mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a shoe production positioning mechanism, including a base, a clamping mechanism on the base, the clamping mechanism including a screw and a transmission block, the screw being rotatably mounted on the base, the transmission block being threadedly connected to the outer wall of the screw, a motor being fixedly mounted on the outer side of the base, the output end of the motor being fixedly connected to the screw, a push rod being rotatably connected to the outer side of the transmission block, multiple sets of push rods being provided, each with a mounting block rotatably connected to its top, each set of mounting blocks being provided with an adapter mechanism, the adapter mechanism including a mounting sleeve and an inner ring, the mounting sleeve being fixed to the mounting block, the inner ring being fixed to the inner side of the mounting sleeve, a sliding rod being slidably mounted on the inner ring, multiple sets of sliding rods being provided, each with a clamping block fixedly mounted at its top, a connecting plate being fixedly mounted at the bottom of each set of sliding rods, a return spring being connected between each set of connecting plates and the inner ring, an inclined groove being provided on the inner wall of the mounting sleeve, multiple sets of inclined grooves being provided, each with an inclined block slidably mounted on its inner side, and an abutment block being fixedly mounted on the inner side of each set of inclined blocks.

[0009] The present invention is further configured such that a sliding groove is provided on the outer wall of the mounting sleeve, a sliding sleeve is slidably provided in the sliding groove, and a push ring is fixedly provided on the inner side of the sliding sleeve. The push ring abuts against the top surface of multiple sets of abutment blocks. This sliding structure design allows the push ring to move smoothly along the sliding groove through the sliding sleeve, thereby achieving precise pushing control of multiple sets of abutment blocks, ensuring that the abutment blocks can move evenly and consistently along the inclined groove and abut against the sliding rod, forming a stable and reliable locking effect. At the same time, the sliding groove also plays a guiding role, preventing the sliding sleeve from shifting or shaking during movement.

[0010] The present invention is further configured such that guide blocks are fixedly provided on the bottom surface of multiple sets of mounting blocks, and guide grooves are provided on the top surface of the base. Multiple sets of guide blocks slide in the guide grooves. This guiding mechanism ensures that the mounting blocks move accurately along a predetermined trajectory under the drive of the motor, preventing offset, tilting or shaking during the clamping process, improving positioning accuracy and clamping stability. At the same time, the design of the guide groove also restricts the degree of freedom of the mounting blocks, so that they can only move radially and will not rotate or shift laterally, ensuring the uniform distribution of clamping force and the consistency of the direction of action.

[0011] This utility model is further configured such that a limiting mechanism is provided on the outer side of the mounting sleeve. The limiting mechanism includes a limiting sleeve and a rotating sleeve. The limiting sleeve is fixed to the outer wall of the sliding sleeve, and the rotating sleeve rotates on the outer wall of the mounting sleeve. A support rod is fixedly provided on the bottom surface of the limiting sleeve. Multiple sets of support rods are provided, and each has a limiting block fixed at its bottom end. A limiting hole is provided on the rotating sleeve. Multiple sets of limiting holes are provided, and each has an unlocking hole at one end. This double limiting mechanism achieves reliable locking of the fitting state through the precise cooperation of the limiting blocks and limiting holes, preventing loosening caused by vibration or external force during clamping. The design of the unlocking hole provides a convenient unlocking channel, allowing the operator to quickly complete the locking or unlocking operation simply by rotating the rotating sleeve without the need for additional tools, greatly improving the ease of operation and safety of the fitting mechanism.

[0012] The present invention is further configured such that an annular groove is provided on the rotating sleeve, and an arc-shaped block is slidably arranged in the annular groove. Multiple sets of arc-shaped blocks are provided, and each of the top ends is fixedly provided with a connecting ring. Each set of connecting rings is connected to the limiting sleeve with a tension spring. The multiple sets of tension springs are respectively arranged on the outside of multiple sets of support rods. This elastic return mechanism ensures that the limiting sleeve can automatically return to the initial position in the unlocked state without the need for manual reset by the operator. The tension spring applies a continuous tension to the limiting sleeve through the connecting rings and the arc-shaped blocks, giving the system an automatic rebound function. At the same time, the sliding design of the arc-shaped block in the annular groove also allows the rotating sleeve to rotate freely without stretching or twisting the tension spring, thereby improving the service life of the components and the reliability of the system.

[0013] The present invention is further configured such that a positioning sleeve is fixedly provided on the bottom surface of the rotating sleeve, and a sliding hole is provided on the inner side of the positioning sleeve. Multiple sets of sliding holes are provided, and each set of sliding holes is connected to a push spring. A positioning block is fixedly provided at the bottom end of each set of push springs. The multiple sets of positioning blocks slide in the multiple sets of sliding holes. A positioning groove is provided on the outer wall of the mounting sleeve. Multiple sets of positioning grooves are provided and abut against the multiple sets of positioning blocks. This elastic positioning structure enables the rotating sleeve to automatically lock at a specific angle position. When the positioning block is embedded in the positioning groove under the action of the push spring, the operator can perceive the locking state through clear tactile feedback, avoiding the risk of incomplete locking or excessive rotation. At the same time, the uniform distribution of multiple sets of positioning blocks and positioning grooves ensures the balance of locking force, improving the stability and reliability of the system in long-term operation.

[0014] The present invention is further configured such that a limiting cylinder is fixedly provided on the inner side of the mounting sleeve, and multiple sets of the limiting cylinder are provided and slidably connected to multiple sets of sliding rods respectively. Guide plates are fixedly provided on the outer walls of multiple sets of sliding rods, and multiple sets of guide plates are slidably connected to multiple sets of limiting cylinders respectively. This dual guiding structure ensures that the sliding rod can only move along the axial direction and will not tilt or rotate. The sliding rod obtains the main motion constraint through the limiting cylinder, while the guide plate provides an additional rotation prevention function, so that the sliding rod always maintains the correct motion trajectory during the fitting process, ensuring that the clamping block can make perpendicular contact with the shoe surface, improving the clamping accuracy and stability, and also reducing the wear between the sliding rod and the limiting cylinder, extending the service life of the components.

[0015] The present invention is further configured such that a rubber block is fixedly provided at the top of each of the multiple sets of clamping blocks, and a support plate is fixedly provided on the base. This flexible contact design achieves gentle clamping of the shoe upper through the elastic deformation characteristics of the rubber block, avoiding scratches, indentations or deformation that may be caused by direct contact with hard clamping blocks. At the same time, the high coefficient of friction of the rubber material also enhances the stability of the clamping force, preventing the shoe from sliding or shifting during processing. The support plate on the base provides a stable and reliable support plane for the sole, forming a complete positioning system of upper clamping and lower support, which together ensures the stability and processing accuracy of the shoe during the production process.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a shoe production positioning mechanism, which has the following beneficial effects:

[0018] 1. The shoe production positioning mechanism provided by this utility model adopts an innovative clamping and fitting system. The motor drives the screw to rotate, realizing the precise displacement of the transmission block, which in turn drives multiple sets of push rods and mounting blocks to move in coordination, forming a uniform enclosure of the shoe body. The clamping blocks on multiple sets of slide rods are equipped with rubber blocks to gently fit the shoe surface, effectively avoiding damage to the shoe material caused by traditional positioning devices. At the same time, the flexible cooperation between the slide rod and the connecting plate allows the clamping blocks to automatically adjust their position according to the shoe contour. The setting of the return spring ensures that the system has good elasticity and adaptability. The guide groove on the base and the guide block at the bottom of the mounting block cooperate to ensure the accuracy and stability of the clamping movement. The combination of the inclined block sliding in the inclined groove and the abutment block constitutes a clever locking mechanism to ensure the reliability and durability of the clamping state.

[0019] 2. The limiting mechanism of this utility model is ingeniously designed. Through the coordinated work of the limiting sleeve and the rotating sleeve, a reliable locking system is formed. The limiting block on the support rod can be accurately embedded in the limiting hole of the rotating sleeve to achieve a firm lock. The design of the unlocking hole makes the unlocking operation simple and convenient. The arc-shaped block connected by the tension spring and the connecting ring form an auxiliary structure with an automatic return function, ensuring that the system can be smoothly reset after unlocking. The push spring inside the positioning sleeve drives the positioning block to cooperate with the positioning groove on the outer wall of the mounting sleeve to realize the automatic positioning and precise locking of the rotating sleeve position. The sliding connection between the limiting cylinder and the slide rod on the inner side of the mounting sleeve and the setting of the guide plate further improve the motion accuracy and stability of the clamping system, making the entire fitting process smoother and more reliable.

[0020] 3. The most significant technical advantage of this utility model lies in its solution to the industry problem that traditional shoe positioning mechanisms are difficult to adapt to different shoe models. The entire system achieves automated positioning through motor drive, eliminating the need for manual adjustment, greatly improving production efficiency and ease of operation. It is particularly suitable for flexible production modes with multiple batches and small quantities. The rubber block design at the top of the clamping block ensures gentle clamping of shoe uppers of various materials, effectively reducing product damage rate. The support plate provides stable support for the sole, preventing displacement and deformation during processing. The locking and unlocking operation of the system is simple and intuitive, requiring only the rotation of the rotating sleeve without the need for complex tools. The automatic reset function of the adaptation mechanism makes the operation more convenient and faster when changing different shoe models. In summary, this utility model significantly improves the flexibility, accuracy, and efficiency of shoe production positioning through innovative mechanical structure design, providing a more practical and reliable technical solution for footwear manufacturers.

[0030] Please see Figures 1-5A shoe production positioning mechanism includes a base 1, on which a clamping mechanism is mounted. The clamping mechanism includes a screw 2 and a transmission block 3. The screw 2 is rotatably mounted on the base 1, and the transmission block 3 is threadedly connected to the outer wall of the screw 2. A motor 4 is fixedly mounted on the outer side of the base 1, and the output end of the motor 4 is fixedly connected to the screw 2. A push rod 5 is rotatably connected to the outer side of the transmission block 3. Multiple sets of push rods 5 are provided, and each set of push rods rotatably connects to a mounting block 6 at its top. Each set of mounting blocks 6 is provided with an adapter mechanism, which includes an installation... The mounting sleeve 7 and the inner ring 8 are fixed on the mounting block 6. The inner ring 8 is fixed inside the mounting sleeve 7. The inner ring 8 is provided with sliding rods 9. Multiple sets of sliding rods 9 are provided, and each set of sliding rods 9 is fixed with a clamping block 10 at its top. Each set of sliding rods 9 is fixed with a connecting plate 11 at its bottom. Each set of connecting plates 11 is connected to the inner ring 8 with a return spring 12. The inner wall of the mounting sleeve 7 is provided with inclined grooves 13. Multiple sets of inclined grooves 13 are provided, and each set of inclined blocks 14 is provided with sliding inclined blocks 14. Each set of inclined blocks 14 is fixed with an abutment block 15 on its inner side.

[0031] The outer wall of the mounting sleeve 7 has a groove 16, and a sliding sleeve 17 is slidably mounted in the groove 16. A push ring 18 is fixedly mounted on the inner side of the sliding sleeve 17. The push ring 18 abuts against the top surface of multiple sets of abutment blocks 15. This is a linear transmission mechanism. The sliding sleeve 17 moves axially in the groove 16 and transmits the motion force to the abutment blocks 15 through the push ring 18. When the sliding sleeve 17 moves, the push ring 18 moves synchronously and applies a uniform pushing force to the abutment blocks 15, so that the abutment blocks 15 can move along the inclined groove 13, thereby converting the radial motion into a lateral clamping force, realizing the stable locking of the sliding rod 9, and ensuring the reliable maintenance of the clamping state.

[0032] Multiple sets of mounting blocks 6 are fixedly provided with guide blocks 19 on their bottom surfaces, and guide grooves 20 are provided on the top surface of the base 1. Multiple sets of guide blocks 19 slide within the guide grooves 20. This is a precision guiding mechanism. The guide blocks 19 and the guide grooves 20 form a sliding pair, ensuring that the mounting blocks 6 can only move along the preset track without deviating or rotating. When the motor 4 drives the push rod 5 through the screw 2 and the transmission block 3, the mounting blocks 6 must strictly move closer to or away from the shoe in the radial direction. The design of the guide grooves 20 prevents the mounting blocks 6 from deflecting or shaking, ensuring the consistency of the clamping force direction and the accuracy of positioning, and improving the stability and reliability of the entire clamping system.

[0033] A limiting mechanism is provided on the outer side of the mounting sleeve 7. The limiting mechanism includes a limiting sleeve 21 and a rotating sleeve 22. The limiting sleeve 21 is fixed to the outer wall of the sliding sleeve 17, and the rotating sleeve 22 rotates on the outer wall of the mounting sleeve 7. A support rod 23 is fixedly provided on the bottom surface of the limiting sleeve 21. Multiple sets of support rods 23 are provided, and each of them has a limiting block 24 fixed at its bottom end. A limiting hole 25 is provided on the rotating sleeve 22. Multiple sets of limiting holes 25 are provided, and each of them has an unlocking hole 26 at one end. This is a rotation locking mechanism. By rotating the rotating sleeve 22, the relative position of the limiting hole 25 and the limiting block 24 is changed to achieve locking and unlocking. When the rotating sleeve 22 rotates to the limiting position, the limiting block 24 is restricted by the inner wall of the limiting hole 25 and cannot move, thereby fixing the limiting sleeve 21 and the sliding sleeve 17 in the current position. When the rotating sleeve 22 rotates to the unlocking position, the limiting block 24 can move freely through the unlocking hole 26, releasing the restriction on the limiting sleeve 21 and allowing the sliding sleeve 17 to slide freely, thus achieving simple and efficient locking control.

[0034] An annular groove 27 is provided on the rotating sleeve 22. An arc-shaped block 28 slides in the annular groove 27. Multiple sets of arc-shaped blocks 28 are provided, and each has a connecting ring 29 fixed at its top. Each set of connecting rings 29 is connected to a tension spring 30 between itself and the limiting sleeve 21. The multiple sets of tension springs 30 are respectively located on the outside of multiple sets of support rods 23. This is an automatic reset mechanism. The tension springs 30 always apply an outward pulling force to the limiting sleeve 21. When the limit is released, the tension springs 30 will automatically pull the limiting sleeve 21 away from the center position. The sliding of the arc-shaped block 28 in the annular groove 27 allows the tension springs 30 to maintain normal operation during the rotation of the rotating sleeve 22 without being twisted. This structural design allows the adapter mechanism to automatically return to the initial state in the unlocked state without the need for manual reset by the operator, improving the convenience of operation and avoiding the problem of forgetting to reset for the next use.

[0035] A positioning sleeve 31 is fixedly provided on the bottom surface of the rotating sleeve 22. A sliding hole 32 is provided on the inner side of the positioning sleeve 31. Multiple sets of sliding holes 32 are provided, and each set of sliding holes 32 is connected to a push spring 33. A positioning block 34 is fixedly provided at the bottom end of each set of push springs 33. The multiple sets of positioning blocks 34 slide in the multiple sets of sliding holes 32 respectively. A positioning groove 35 is provided on the outer wall of the mounting sleeve 7. Multiple sets of positioning grooves 35 are provided and abut against the multiple sets of positioning blocks 34 respectively. This is an automatic positioning mechanism. When the rotating sleeve 22 rotates, the push spring 33 continuously pushes the positioning block 34 to extend outward. When the positioning block 34 is aligned with the positioning groove 35, it automatically inserts and abuts against the positioning groove 35 under the action of the push spring 33, thereby locking the angular position of the rotating sleeve 22. The cooperation between the positioning block 34 and the positioning groove 35 produces obvious tactile feedback, allowing the operator to perceive the completion of the locking without visual inspection. It also prevents the rotating sleeve 22 from rotating due to vibration or accidental contact, ensuring the reliable maintenance of the locked state.

[0036] A limiting cylinder 36 is fixedly installed inside the mounting sleeve 7. Multiple sets of limiting cylinders 36 are provided and are slidably connected to multiple sets of sliding rods 9. Guide plates 37 are fixedly installed on the outer walls of multiple sets of sliding rods 9. The multiple sets of guide plates 37 are slidably connected to multiple sets of limiting cylinders 36. This is a dual guiding system. The limiting cylinders 36 provide the main axial movement guidance for the sliding rods 9, preventing the sliding rods 9 from deviating or tilting during movement. The sliding cooperation between the guide plates 37 and the limiting cylinders 36 further prevents the rotation of the sliding rods 9. This dual constraint ensures that the sliding rods 9 can only reciprocate radially, ensuring that the clamping block 10 always maintains the correct direction and posture of movement, so that it can make perpendicular contact with the shoe surface, improving the accuracy and uniformity of clamping. At the same time, by increasing the contact area, the wear between the sliding rods 9 and the limiting cylinders 36 is also reduced, extending the service life of the components.

[0037] Each of the multiple clamping blocks 10 has a rubber block 38 fixed at its top, and a support plate 39 is fixed on the base 1. This is a flexible contact system. The rubber block 38 has good elasticity and friction characteristics, and can deform appropriately according to the shape of the shoe upper to form a larger contact area. This not only improves the clamping force but also reduces the pressure per unit area, effectively preventing damage and deformation of the shoe upper that may be caused by direct contact with hard clamping blocks. The support plate 39 provides a stable bottom support plane, forming a complete "upper clamping and lower support" positioning system with the upper clamping mechanism. This ensures that the shoe maintains a stable posture during processing and will not slip or shift, thereby improving processing accuracy and product quality.

[0038] In this embodiment, during use, the shoe is placed on the support plate 39, and the motor 4 is started to drive the screw 2 to rotate and engage with the transmission sleeve via threads. This causes the transmission sleeve to push multiple sets of push rods 5, which in turn push the mounting blocks 6 to move. The mounting blocks 6 slide along the guide groove 20 via the guide block 19, and each of the mounting blocks 6 drives the mounting sleeve 7 to move, causing multiple sets of rubber blocks 38 to abut against the outside of the shoe. Multiple sets of sliding rods 9 slide along the limiting cylinder 36 and the inner ring 8, and stretch the return spring 12 via the connecting plate 11, so that the multiple sets of rubber blocks 38 are in a position that fits the shoe. Multiple sets of tension springs 30 pull the limiting sleeve 21 and the sliding sleeve 17 to slide along the sliding groove 16, and push the multiple sets of abutting blocks 15 to slide along the inclined groove 13 through the inclined block 14, so that the multiple sets of abutting blocks 15 abut against the outer wall of the sliding rod 9. At this time, the multiple sets of limiting blocks 24 are respectively in the multiple sets of unlocking holes 26. Rotating the rotating sleeve 22 causes the multiple sets of limiting blocks 24 to slide into the limiting hole 25 to restrict the limiting sleeve 21. Multiple sets of push springs 33 push the positioning block 34 to abut against the outside of the positioning groove 35 to position the rotating sleeve 22, so that the multiple sets of rubber blocks 38 are fixed in the fit with the shoe.

[0039] More specifically, when it is necessary to adapt to other shoe models, the adaptation mechanism needs to be unlocked. Rotating the rotating sleeve 22 drives the positioning sleeve 31 to rotate, and through multiple sets of positioning grooves 35, pushes multiple sets of positioning blocks 34 to slide along the sliding hole 32 and squeezes the push spring 33, so that the multiple sets of positioning blocks 34 continuously move within the multiple sets of positioning grooves 35. When the multiple sets of limiting blocks 24 slide along the limiting hole 25 into the unlocking hole 26, the restriction on the limiting sleeve 21 is released, and the limiting sleeve 21 is pushed to drive the sliding sleeve 17 to slide along the sliding groove 16 and stretch the multiple sets of tension springs 30. At the same time, the push ring 18 is driven to release the push on the multiple sets of abutting blocks 15, so that the multiple sets of abutting blocks 15 release the abutment on the sliding rod 9. Through multiple sets of reset springs 12, the connecting plate 11 is pulled and the multiple sets of sliding rods 9 are reset. Then the above operation can be repeated to adjust the adaptation mechanism.

[0040] In summary, during use or operation of the overall equipment: When in use, the shoe is placed on the tray 39. The motor 4 is started, driving the screw 2 to rotate and engage with the transmission sleeve via a threaded connection. This causes the transmission sleeve to push multiple sets of push rods 5, which in turn push the mounting blocks 6 to move. The mounting blocks 6 slide along the guide groove 20 via the guide block 19, and each mounting block 6 drives the mounting sleeve 7 to move, causing multiple sets of rubber blocks 38 to abut against the outside of the shoe. Multiple sets of sliding rods 9 slide along the limiting cylinder 36 and the inner ring 8, and stretch the return spring 12 via the connecting plate 11, ensuring that the multiple sets of rubber blocks 38 are positioned in contact with the shoe. In the fitted state, multiple sets of tension springs 30 pull the limiting sleeve 21 and the sliding sleeve 17 to slide along the sliding groove 16, and push the multiple sets of abutting blocks 15 to slide along the inclined groove 13 through the inclined block 14, so that the multiple sets of abutting blocks 15 abut against the outer wall of the sliding rod 9. At this time, the multiple sets of limiting blocks 24 are respectively in the multiple sets of unlocking holes 26. Rotating the rotating sleeve 22 causes the multiple sets of limiting blocks 24 to slide into the limiting hole 25 to restrict the limiting sleeve 21. Multiple sets of push springs 33 push the positioning block 34 to abut against the outside of the positioning groove 35 to position the rotating sleeve 22, so that the multiple sets of rubber blocks 38 are fixed in the fitted state with the shoe.

[0041] When it is necessary to adapt to other shoe models, the adaptation mechanism needs to be unlocked. Rotating the rotating sleeve 22 drives the positioning sleeve 31 to rotate, and through multiple sets of positioning grooves 35, pushes multiple sets of positioning blocks 34 to slide along the sliding hole 32 and squeezes the push spring 33, so that the multiple sets of positioning blocks 34 continuously move within the multiple sets of positioning grooves 35. When the multiple sets of limiting blocks 24 slide along the limiting hole 25 into the unlocking hole 26, the restriction on the limiting sleeve 21 is released, and the limiting sleeve 21 is pushed to drive the sliding sleeve 17 to slide along the sliding groove 16 and stretch the multiple sets of tension springs 30. At the same time, the push ring 18 is driven to release the push on the multiple sets of abutting blocks 15, so that the multiple sets of abutting blocks 15 release the abutment on the sliding rod 9. Through multiple sets of reset springs 12, the connecting plate 11 is pulled and the multiple sets of sliding rods 9 are reset. Then the above operation can be repeated to adjust the adaptation mechanism.

These will not be elaborated on here. For all the fixed connections mentioned above, welding is the preferred option.

[0043] In all the solutions mentioned above, the operation of electrical components, unless otherwise specified, is controlled by a controller. Since the devices matched with the controllers are common devices, their control principles and wiring connections are existing, well-known, and mature technologies, and their specific circuit structures will not be described in detail here.
