Description

Technical Field

[0001] This invention relates to the field of shoe toe shaping technology, specifically a highly adaptable shoe toe heat and cold shaping machine and shaping method. Background Technology

[0002] In footwear manufacturing, heat and cold setting of the toe is a crucial process for shaping and maintaining the shoe's shape. Existing heat and cold setting machines for toes generally employ a combination of a pressing component and the shoe lining to achieve the setting process. The working principle is as follows: the heated and softened toe is placed on the shoe lining, and then a drive mechanism controls the pressing component to press down, causing the toe material to fit tightly against the outer contour of the shoe lining. After holding the pressure and cooling, the desired three-dimensional shape is achieved.

[0003] However, to ensure a proper fit between the toe and the lining, the pressing component needs to apply significant force continuously to the toe surface, resulting in substantial friction at the interface. Particularly noteworthy is that existing equipment typically employs a simple linear up-and-down motion trajectory for the pressing component. In this mode, during a single shaping cycle, the pressing component experiences sliding friction with the toe surface in both the downward pressing and upward resetting phases. While lateral friction usually doesn't cause visible damage to the toe itself, the wear on the inner side of the pressing component is continuous and cumulative. With increasing production batches, the wear on critical working surfaces of the pressing component multiplies, leading to a gradual decrease in its inner thickness and shape accuracy, reducing the lifespan of the pressing component itself. Furthermore, the gradual inaccuracy of the shaping mold can affect the consistency of subsequent toe shaping and the final product quality. Summary of the Invention

[0004] The purpose of this invention is to provide a highly adaptable shoe toe heat and cold setting machine and setting method to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A highly adaptable shoe toe heat and cold setting machine, comprising:

[0007] A frame, on which a shoe liner and two sets of pressing parts adapted to the shoe liner are provided;

[0008] A drive assembly, disposed on the frame and connected to the two sets of pressing members, is used to drive the pressing members toward or away from the shoe lining;

[0009] An elastic connection assembly connects the drive assembly and the pressing member, and the elastic connection assembly is provided with a protruding shaft.

[0010] The side plate is fixedly installed on the frame. The side plate can guide the movement of the elastic connection assembly. The side plate is provided with a switching groove. The switching groove cooperates with the convex shaft. When the two sets of pressing parts cooperate with the shoe lining and complete the shaping of the shoe toe, the two sets of pressing parts can move away from the shoe lining in a direction parallel to the lower end surface of the shoe lining.

[0011] The high-adaptability shoe toe heat and cold setting machine described above: the drive assembly includes a bracket fixedly installed on the frame and a first electric telescopic rod fixedly installed on the frame. A connecting plate is provided on the actuating end of the first electric telescopic rod. An extension shaft is connected to the connecting plate. Multiple sets of grooved wheels are rotatably installed at one end of the extension shaft. The grooved wheels can roll in the guide grooves opened in the side plate.

[0012] The other end of the extension shaft is connected to the elastic connection assembly.

[0013] The high-adaptability shoe toe heat and cold setting machine described above: the elastic connection assembly includes a connecting sleeve sleeved on the extension shaft and an arc-shaped component detachably connected to the pressing component, wherein the arc-shaped component and the connecting sleeve are connected by a connecting rod;

[0014] The elastic connection assembly further includes a first cylindrical spring sleeved on the extension shaft, one end of the first cylindrical spring being connected to the connecting sleeve and the other end being connected to the end of the extension shaft.

[0015] The high-adaptability shoe toe heat and cold setting machine described above: the inner wall of the connecting sleeve is provided with a protrusion along its length direction, and the outer wall of the extension shaft is provided with a groove along its length direction. The protrusion and the groove slide together, which can axially lock the connecting sleeve and the extension shaft.

[0016] The high-adaptability shoe toe heat and cold setting machine described above: the switching groove includes a vertical groove and a horizontal groove that are perpendicular to each other and are disposed on the side plate. The end of the vertical groove away from the horizontal groove is connected to the end of the horizontal groove away from the vertical groove through an arc groove.

[0017] The end of the vertical groove away from the horizontal groove is also connected to a compensation groove that is collinear with it.

[0018] A deflector is rotatably mounted at the connection between the vertical groove and the arc groove. The deflector has a built-in torsion spring on its shaft, and the deflector can change the movement trajectory of the convex shaft when the convex shaft performs a lifting action.

[0019] The high-adaptability shoe toe heat and cold setting machine described above: the frame is also provided with a support plate parallel to the lower end face of the pressing part, the support plate is connected to the frame by a connecting shaft, a third columnar spring is sleeved on the connecting shaft, one end of the third columnar spring is connected to the frame, and the other end is connected to the support plate.

[0020] The high-adaptability shoe toe heat and cold setting machine described above: a laser marking device is also fixedly installed on the bracket, and the laser marking device can generate a positioning beam on the shoe lining.

[0021] The high-adaptability shoe toe heat and cold setting machine as described above: multiple sets of second electric telescopic rods are fixedly installed on the machine frame, and the moving end of the second electric telescopic rod is fixedly connected to the shoe lining;

[0022] The shoe lining has multiple sets of through holes, and a top rod is slidably installed in each through hole. The top rod is slidably connected to the frame, and a second cylindrical spring is sleeved on the top rod. One end of the second cylindrical spring is connected to the frame, and the other end is connected to the top rod.

[0023] A method for shaping the toe of a shoe using the aforementioned high-adaptability toe heat and cold setting machine includes the following steps:

[0024] Step 1: Place the shoe toe to be shaped in the heating device and heat the shoe toe to 100-120°C;

[0025] Step 2: Place the toe of the shoe on the support plate and use the positioning beam to position the toe;

[0026] Step 3: The driving component drives the elastic connecting component to move, so that the two sets of pressed parts that are pressed together can move vertically downward until the pressed parts act on the toe of the shoe and cause the toe of the shoe to bend and deform and fit against the inner lining of the shoe.

[0027] Step 4: The pressing component holds the pressing action for 7-15 seconds. Then the pressing component and the shoe liner move towards the frame synchronously. When the pressing component descends to the lower end of the stroke, the cam shaft engages with the switching groove, allowing the two sets of pressing components to move away from the shoe liner. At the same time, the push rod acts on the shaped shoe toe, pushing it out from the shoe liner, thus completing the hot and cold shaping of the shoe toe.

[0028] Step 5: The drive component drives the elastic connection component and the pressing component to reset. When the pressing component moves to the highest point of its stroke, the two sets of pressing components reset to the mating state.

[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] By using the designed drive assembly, elastic connection assembly, and side plate, firstly, with the cooperation of the cam shaft and the switching groove, the two sets of pressing components can maintain a tight fit in the initial state, avoiding gaps between them that could cause indentations on the toe surface during the toe shaping process. Secondly, after the pressing components have completed the toe shaping, they not only move away from the shoe lining but also move away from each other. This ensures that the pressing components will not rub against the toe when moving upwards, preventing unnecessary wear. Furthermore, when the pressing components separate from the shoe lining, the inner side of the pressing components will not rub against the toe, preventing localized abnormal wear. This improves the durability of the pressing components and ensures the accuracy of toe shaping during continuous production.

[0031] By incorporating a shoe liner, a second electric telescopic rod, and a top rod, the pressing component and shoe liner can move synchronously after the shoe toe is shaped, thus avoiding friction between the pressing component and the shoe toe. Furthermore, when the pressing component reaches the lower end of its stroke, the pressing effect on the shoe toe can be removed. At this point, the top rod can lift the shoe toe, separating it from the shoe liner. This achieves automatic feeding, reduces manual intervention, and improves the automation level of the device.

[0043] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0044] Please see Figures 1-10 As an embodiment of the present invention, the high-adaptability shoe toe heat and cold setting machine includes: a frame 1, a drive assembly, an elastic connection assembly and a side plate 12.

[0045] The frame 1 is provided with a shoe liner 2 and two sets of pressing parts 5 adapted to the shoe liner 2. When the two sets of pressing parts 5 are in a fitted state, the contour formed by their inner sides is the same as the outer contour of the shoe liner 2, and the gap between the pressing parts 5 and the shoe liner 2 is equivalent to the thickness of the shoe toe.

[0046] The drive assembly is mounted on the frame 1 and connected to the two sets of pressing members 5. The drive assembly is used to drive the pressing members 5 to move toward or away from the shoe lining 2.

[0047] The drive assembly includes a bracket 14 fixedly mounted on the frame 1 and a first electric telescopic rod 15 fixedly mounted on the frame 1. A connecting plate 11 is provided on the actuating end of the first electric telescopic rod 15. An extension shaft 10 is connected to the connecting plate 11. A plurality of grooved wheels 1002 are rotatably mounted on one end of the extension shaft 10. The grooved wheels 1002 can roll in the guide groove 1201 opened in the side plate 12.

[0048] The other end of the extension shaft 10 is connected to the elastic connection assembly.

[0049] In this embodiment, when the first electric telescopic rod 15 is activated, it can drive the two sets of pressing parts 5 connected to it to perform lifting and lowering actions through the connecting plate 11. In the initial state, the shoe toe to be heated and cooled will be heated first and then placed above the shoe lining 2. At this time, the pressing part 5 will move downward and act on the shoe toe, so that the shoe toe can fit on the shoe lining 2 and undergo corresponding deformation to form the three-dimensional structure of the shoe toe. After holding for a certain period of time, the shoe toe will cool and solidify. Based on this operation, the shoe toe can maintain the external contour of the shoe lining 2 under the support of the shoe lining 2, thereby achieving a perfect shaping effect.

[0050] The cooperation between the grooved wheel 1002 and the guide groove 1201 ensures the directional accuracy of the two sets of pressing parts 5 during movement.

[0051] Please see Figures 4-6 The elastic connecting component connects the driving component and the pressing component 5, and the elastic connecting component is provided with a protruding shaft 8;

[0052] The elastic connection assembly includes a connecting sleeve 7 sleeved on the extension shaft 10 and an arc-shaped component 4 detachably connected to the pressing component 5. The arc-shaped component 4 and the connecting sleeve 7 are connected by a connecting rod 6.

[0053] The elastic connection assembly also includes a first cylindrical spring 9 sleeved on the extension shaft 10, one end of the first cylindrical spring 9 being connected to the connecting sleeve 7 and the other end being connected to the end of the extension shaft 10;

[0054] The inner wall of the connecting sleeve 7 is provided with a protrusion 701 along its length direction, and the outer wall of the extension shaft 10 is provided with a groove 1001 along its length direction. The protrusion 701 and the groove 1001 slide to engage, thereby axially locking the connecting sleeve 7 and the extension shaft 10 to prevent axial rotation between the connecting sleeve 7 and the extension shaft 10 and to ensure that the convex shaft 8 can be precisely engaged with the switching groove.

[0055] In the initial state, the first columnar spring 9 is stretched, causing the connecting sleeve 7 to tend to move toward the extension shaft 10. However, the convex shaft 8 is engaged with the switching groove, which suppresses the tendency of the connecting sleeve 7 to move toward the extension shaft 10. Thus, in the initial state, the two sets of pressing parts 5 can be in a close fit with each other. After the hot and cold shaping of the shoe toe is completed, when the pressing part 5 moves to the lower end of its stroke, the first columnar spring 9 can pull the connecting sleeve 7 away from the shoe toe in a direction parallel to the lower end of the shoe lining 2, thereby increasing the gap between the pressing part 5 and the shoe lining 2. When the first electric telescopic rod 15 drives the pressing part 5 to move, it can make the pressing part 5 move upward while maintaining the state of separation from the shaped shoe toe. Thus, during the upward movement of the pressing part 5 and its separation from the shoe toe, no friction is generated between it and the shoe toe, thereby reducing the friction experienced by the pressing part 5 during a single shaping process, reducing unnecessary wear of the pressing part 5, improving its durability and the accuracy of subsequent shoe toe shaping processes.

[0056] Furthermore, in this embodiment, the first electric telescopic rod 15 synchronously controls the movement of the two sets of pressing parts 5 through the connecting plate 11, which makes the movement of the two sets of pressing parts 5 more consistent, preventing obvious indentations from appearing on the surface of the shoe toe during pressing due to the height difference of the pressing parts 5, and improving the shaping quality of the shoe toe.

[0057] Please see Figures 2-5 , Figure 7 The side plate 12 is fixedly installed on the frame 1. The side plate 12 can guide the movement of the elastic connection assembly. The side plate 12 is provided with a switching groove. The switching groove cooperates with the convex shaft 8. When the two sets of pressing parts 5 cooperate with the shoe lining 2 and complete the shaping of the shoe toe, the two sets of pressing parts 5 can move away from the shoe lining 2 in a direction parallel to the lower end surface of the shoe lining 2.

[0058] The switching slot includes a vertical slot 1202 and a horizontal slot 1204 that are perpendicular to each other and are disposed on the side plate 12. The end of the vertical slot 1202 away from the horizontal slot 1204 is connected to the end of the horizontal slot 1204 away from the vertical slot 1202 through an arc-shaped slot 1205.

[0059] The end of the vertical groove 1202 away from the horizontal groove 1204 is also connected to a compensation groove 1203 that is collinear with it;

[0060] A deflector 13 is rotatably mounted at the connection between the vertical groove 1202 and the arc groove 1205. The shaft of the deflector 13 has a built-in torsion spring, and the deflector 13 can change the movement trajectory of the convex shaft 8 when the convex shaft 8 performs a lifting action.

[0061] In this embodiment, in the initial state, the convex shaft 8 is located at the end of the compensation groove 1203 away from the transverse groove 1204. At this time, the two sets of pressing parts 5 are in a tightly fitted state. In this state, when the two sets of pressing parts 5 move downward, they can cooperate with the shoe lining 2 to achieve the shaping of the shoe toe.

[0062] Specifically, when the first electric telescopic rod 15 drives the extension shaft 10 to move downward, the extension shaft 10 will drive the connecting sleeve 7, connecting rod 6, arc-shaped part 4 and pressing part 5 to move downward. At the same time, the convex shaft 8 will move along the length direction of the compensation groove 1203 and the vertical groove 1202, so that the two sets of pressing parts 5 can move towards the shoe lining 2 in a tightly fitted state, thereby shaping the shoe toe.

[0063] After the toe is shaped, the convex shaft 8 will continue to move downward along the length of the vertical groove 1202. When the convex shaft 8 moves to the end of the vertical groove 1202, the first cylindrical spring 9 will release its elastic potential energy, which will drive the connecting sleeve 7, connecting rod 6, arc-shaped part 4 and pressing part 5 away from the shoe lining 2. At this time, the gap between the pressing part 5 and the shoe lining 2 will increase, so that when the pressing part 5 moves upward, it will no longer rub against the shaped toe, thereby reducing the wear of the pressing part 5 and improving its durability.

[0064] Furthermore, when the first cylindrical spring 9 pulls the connecting sleeve 7 to move, the convex shaft 8 will move along the transverse groove 1204. When the connecting sleeve 7, connecting rod 6, arc-shaped member 4 and pressing member 5 move upward, the convex shaft 8 will move along the arc-shaped groove 1205. When the convex shaft 8 moves to the end of the arc-shaped groove 1205, the convex shaft 8 can act on the deflector 13, causing the deflector 13 to rotate and the torsion spring to be compressed. After that, the convex shaft 8 will continue to rise and move along the compensation groove 1203. At this time, the two sets of pressing members 5 can be reset to a tightly fitted state. At the same time, when the convex shaft 8 separates from the deflector 13, the deflector 13 can be reset under the action of the torsion spring, so that when the convex shaft 8 moves downward next time, it can move along the compensation groove 1203 and the vertical groove 1202.

[0065] Furthermore, in the application, the two sets of side plates 12 connecting the two sets of pressing parts 5 are oriented differently. Specifically, the two sets of side plates 12 are perpendicular to the tangent at the midpoint of the corresponding pressing part 5, so that when the two sets of pressing parts 5 move to the lower end of the stroke, the two sets of pressing parts 5 can not only move away from the shoe lining 2, but also move away from each other. Compared with keeping the two sets of pressing parts 5 in a close fit and moving away from the shoe lining 2, the movement of the two sets of pressing parts 5 away from each other can avoid the friction between the inner side of the pressing part 5 and the shaped shoe toe when it moves away from the shoe lining 2, thereby avoiding the occurrence of abnormalities in local areas of the pressing part 5.

[0066] Based on the above settings, firstly, with the cooperation of the convex shaft 8 and the switching groove, the two sets of pressing parts 5 can maintain a tight fit in the initial state, avoiding gaps between them that could cause indentations on the toe surface during the toe shaping process. Secondly, after the pressing parts 5 have completed the toe shaping, they not only move away from the shoe lining 2 but also move away from each other. This ensures that the pressing parts 5 will not rub against the toe when moving upwards, preventing unnecessary wear. Furthermore, when the pressing parts 5 separate from the shoe lining 2, the inner side of the pressing parts 5 will not rub against the toe, preventing localized abnormal wear. This improves the durability of the pressing parts 5 and ensures the accuracy of toe shaping during continuous production.

[0067] Please see Figures 1-4 The frame 1 is also provided with a support plate 3 parallel to the lower end face of the pressing part 5. The support plate 3 is connected to the frame 1 through a connecting shaft 20. A third columnar spring 21 is sleeved on the connecting shaft 20. One end of the third columnar spring 21 is connected to the frame 1, and the other end is connected to the support plate 3.

[0068] A laser marking device 16 is also fixedly installed on the bracket 14, which can generate a positioning beam on the shoe lining 2.

[0069] In this embodiment, in the initial state, the third columnar spring 21 is in a compressed state. At this time, the height of the support plate 3 is higher than the height of the shoe lining 2. At the same time, the laser marking device 16 can generate a positioning beam on the shoe lining 2. When the shoe toe to be shaped is placed on the support plate 3, the positioning beam can illuminate the shoe toe, thus providing the operator with a positioning reference and ensuring the accuracy of the initial placement position of the shoe toe.

[0070] When the pressing component 5 moves downward and comes into contact with the toe of the shoe, the toe of the shoe can be pressed between the support plate 3 and the pressing component 5. At this time, the support plate 3 can move toward the shoe lining 2. When the shoe lining 2 protrudes from the support plate 3, it can lift the toe of the shoe. At this time, the toe of the shoe pressed between the support plate 3 and the pressing component 5 can shrink and fit onto the shoe lining 2, thereby completing the heat and cold setting.

[0071] Please see Figures 1-3 , Figures 8-10 Multiple sets of second electric telescopic rods 17 are fixedly installed on the frame 1, and the actuating end of the second electric telescopic rod 17 is fixedly connected to the shoe lining 2.

[0072] The shoe lining 2 is provided with multiple sets of through holes 201. A top rod 18 is slidably installed in the through holes 201. The top rod 18 is slidably connected to the frame 1. A second columnar spring 19 is sleeved on the top rod 18. One end of the second columnar spring 19 is connected to the frame 1, and the other end is connected to the top rod 18.

[0073] In this embodiment, in the initial state, the second electric telescopic rod 17 can support the shoe lining 2, while the second columnar spring 19 is in a natural state, and the upper surface of the top rod 18 is coplanar with the upper surface of the shoe lining 2.

[0074] When the pressing component 5 moves downward and cooperates with the shoe liner 2 to shape the toe, the first electric telescopic rod 15 and the second electric telescopic rod 17 will move synchronously, so that the pressing component 5 and the shoe liner 2 can move towards the frame 1 synchronously. During this process, the second columnar spring 19 is stretched, and the pressing component 5 will not move relative to the toe, that is, no friction will be generated, thereby further avoiding abnormal wear of the pressing component 5. When the pressing component 5 and the shoe liner 2 descend to the end of the stroke, the pressing component 5 can move away from the shoe liner 2 and remove the pressing effect on the toe. At this time, the second columnar spring 19 releases elastic potential energy, driving the top rod 18 to move and protrude from the upper surface of the shoe liner 2. At this time, the toe placed on the shoe liner 2 can be lifted and separated from the shoe liner 2, thereby realizing the automatic unloading of the shaped toe.

[0075] Based on the above settings, after the toe is shaped, the pressing component 5 and the shoe liner 2 can move synchronously, thus avoiding friction between the pressing component 5 and the toe. When the pressing component 5 moves to the lower end of its stroke, the pressing effect on the toe can be removed. At this time, the top rod 18 can lift the toe, separating the toe from the shoe liner 2, realizing automatic feeding, reducing manual intervention, and improving the automation level of the device.

[0076] As an embodiment of the present invention, a method for shaping the toe of a shoe using the aforementioned high-adaptability toe heat and cold setting machine is also proposed, comprising the following steps:

[0077] Step 1: Place the shoe toe to be shaped in the heating device and heat the shoe toe to 100-120°C;

[0078] Step 2: Place the toe of the shoe on support plate 3 and use the positioning beam to position the toe of the shoe;

[0079] Step 3: The driving component drives the elastic connecting component to move, so that the two sets of pressed parts 5 that are stuck together can move vertically downward until the pressed parts 5 act on the toe of the shoe and cause the toe of the shoe to bend and deform and stick to the shoe lining 2.

[0080] Step 4: Pressing component 5 maintains the pressing action for 7-15 seconds, and then pressing component 5 and shoe liner 2 move synchronously toward frame 1. When pressing component 5 descends to the lower end of the stroke, the cam shaft 8 cooperates with the switching groove, so that the two sets of pressing components 5 can move away from shoe liner 2. At the same time, the push rod 18 acts on the shoe toe that has been shaped, pushing it out from the shoe liner 2, thus completing the hot and cold shaping of the shoe toe.

[0081] Step 5: The driving component drives the elastic connection component and the pressing component 5 to reset. When the pressing component 5 moves to the highest point of its stroke, the two sets of pressing components 5 reset to the mating state.

[0082] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.

7. A high-adaptability shoe toe heat and cold setting machine according to claim 6, characterized in that, A laser marking device is also fixedly installed on the bracket, which can generate a positioning beam on the shoe lining.

8. A high-adaptability shoe toe heat and cold setting machine according to claim 7, characterized in that, Multiple sets of second electric telescopic rods are fixedly installed on the frame, and the actuating end of the second electric telescopic rod is fixedly connected to the shoe lining. The shoe lining has multiple sets of through holes, and a top rod is slidably installed in each through hole. The top rod is slidably connected to the frame, and a second cylindrical spring is sleeved on the top rod. One end of the second cylindrical spring is connected to the frame, and the other end is connected to the top rod.

9. A method for shaping a shoe toe using a high-adaptability shoe toe heat and cold setting machine as described in claim 8, characterized in that, Includes the following steps: Step 1: Place the shoe toe to be shaped in the heating device and heat the shoe toe to 100-120°C; Step 2: Place the toe of the shoe on the support plate and use the positioning beam to position the toe; Step 3: The driving component drives the elastic connecting component to move, so that the two sets of pressed parts that are pressed together can move vertically downward until the pressed parts act on the toe of the shoe and cause the toe of the shoe to bend and deform and fit against the inner lining of the shoe. Step 4: The pressing component holds the pressing action for 7-15 seconds. Then the pressing component and the shoe liner move towards the frame synchronously. When the pressing component descends to the lower end of the stroke, the cam shaft engages with the switching groove, allowing the two sets of pressing components to move away from the shoe liner. At the same time, the push rod acts on the shaped shoe toe, pushing it out from the shoe liner, thus completing the hot and cold shaping of the shoe toe. Step 5: The drive component drives the elastic connection component and the pressing component to reset. When the pressing component moves to the highest point of its stroke, the two sets of pressing components reset to the mating state.
