Description

Technical Field

[0001] This utility model relates to the field of shoemaking technology, and more specifically, to a shoe material preform foaming hanger. Background Technology

[0002] After the initial shoe material blanks are foamed and molded, there is still residual moisture and foaming auxiliary material inside. They need to be suspended and left to ventilate and set. If they are stacked, the initial shoe material blanks are easily squeezed and deformed, and the surface sticks together. Moreover, the internal moisture is difficult to dissipate quickly, which will seriously affect the processing quality of subsequent cutting, bonding and molding processes. Therefore, in the process of shoe material foaming production, special hanging equipment is generally required to turn over, hang and place the initial shoe material blanks for natural drying.

[0003] Currently, the conventional hanging and placement equipment used in the industry is mostly a simple structure with a fixed frame and fixed hanging position. It can only realize the basic hanging and bearing function of the initial shoe material blank. The structure is simple and it is a commonly used auxiliary tooling in the foaming production of shoe materials.

[0004] In actual production and operation, existing conventional hanging equipment still has significant shortcomings: On the one hand, the hanging positions are mostly fixed, making it impossible to flexibly adjust the spacing and hanging angle according to different specifications and sizes of shoe material preforms. This restricts the material placement layout, results in low overall space utilization, and reduces the flexibility of manual hanging and unloading of materials. On the other hand, traditional hanging methods lack effective anti-slip limiting and synchronous control structures. After hanging, shoe material preforms are easily affected by external forces such as workshop movement and handling, causing them to shake, shift, or even fall off and be damaged. At the same time, it is impossible to simultaneously hang and unload multiple groups of materials, requiring individual operation, which is labor-intensive and results in low turnover and storage efficiency during batch production. It is difficult to meet the needs of large-scale, assembly-line production of shoe material preforms. Therefore, we urgently need a shoe material preform foaming rack to solve the above problems. Utility Model Content

[0005] One objective of this invention is to provide a new technical solution for a shoe material preform foaming hanger. By setting a sliding adjustable crossbeam, a lockable rotating rod, and a hinged hook structure with three working states, combined with a magnetic snap-lock linkage opening and closing design, it can achieve flexible hanging of shoe materials, static locking to prevent shaking, and simultaneous and convenient material unloading, thereby improving ventilation and shaping quality and production turnover efficiency.

[0006] According to a first aspect of the present invention, a shoe material preform foaming rack is provided, including a frame and universal wheels installed at the four corners of the bottom of the frame, and a crossbeam slidably disposed on the frame. A hanging net is fixedly installed on the crossbeam, and a buckle for engaging with the cross joint of the hanging net is fixedly installed on the rear side of the crossbeam. A hook for hanging shoe preforms is rotatably disposed on the crossbeam.

[0007] The crossbeam is equipped with a driving component for rotating the hooks. The driving component includes rectangular slots that are linearly and equidistantly spaced along the length of the crossbeam. The crossbeam has through holes that communicate with the rectangular slots. A rotating rod is rotatably connected to the through hole via a bearing. A sleeve is fixedly installed on one end of the crossbeam at the through hole. One end of the rotating rod is rotatably connected to the sleeve via a bearing. There are multiple sets of hooks, and each set of hooks is located in a corresponding rectangular slot and sleeved on the rotating rod. When the rotating rod rotates, the hooks rotate along the axis of the rotating rod.

[0008] A retaining rod is provided on the crossbeam at the position corresponding to the rectangular groove. The retaining rod has a fastening groove and a damping pad is wrapped inside the fastening groove. When the end of the hook is inserted into the fastening groove, a first working area is formed. When the end of the hook is disengaged from the fastening groove, a second working area is formed. When in the first working area, the end of the hook abuts against the damping pad to form an anti-slip area.

[0009] Optionally, the number of crossbeams is multiple sets, and the multiple sets of crossbeams are slidably mounted on the frame via U-shaped brackets on both sides. The frame is provided with a first limiting hole, and the crossbeam is provided with a second limiting hole that matches the first limiting hole. When the first limiting hole and the second limiting hole are coaxial, they are locked together by bolts to form an installation area.

[0010] Optionally, a mounting ring is fixedly connected to one side of the crossbeam, and the inner wall of the mounting ring is provided with a meshing groove. A telescopic rod is fixedly installed at the other end of the rotating rod through a placement hole. A toggle ring is fixedly connected to the movable end of the telescopic rod. The toggle ring consists of a meshing section and a toggle section. The meshing section has meshing teeth integrally formed to match the meshing groove, and the toggle section is provided with anti-slip knurling. When the meshing teeth mesh with the meshing groove, the rotating rod is in the locking zone. When the meshing teeth disengage from the meshing groove, the rotating rod is in the unlocking zone.

[0011] Optionally, the hook consists of a straight section and a bent section. The straight section is connected to a rotating rod, and a magnetic groove is provided at the end of the straight section. The magnetic groove is hinged to the end of the bent section through a connecting rod. A magnetic block adapted to the magnetic groove is fixedly installed on the side of the bent section that contacts the inner wall of the magnetic groove. When the bent section abuts against the magnetic groove, the magnetic block and its inner wall form a magnetic fixing area.

[0012] Optionally, an elastic buckle is fixedly connected to the straight segment, and a positioning rod adapted to the elastic buckle is fixedly connected to the bent segment. When the end of the positioning rod is inserted into the elastic buckle, a positioning area is formed. The bent segments of multiple sets of hooks are connected by a pull rod. When the pull rod is moved, the multiple sets of bent segments rotate along the axis of the connecting rod.

[0013] Optionally, an anti-slip sleeve is fixedly connected to the end of the pull rod.

[0014] 1. According to one embodiment of this disclosure, the shoe material preform foaming rack features an integrated frame with bottom casters, allowing the entire machine to move freely and turn on the spot. It can flexibly move between the hanging area, foaming resting area, and unloading area without manual handling or hoisting, saving time and effort. Combined with a sliding multi-beam system, U-shaped frame guide limit, and limit hole bolt locking structure, the beam spacing can be adjusted freely according to different styles and sizes of shoe material preforms, adapting to multi-specification production. The layered beam layout forms independent ventilation spaces, which is beneficial for all-round moisture dissipation and drying of the shoe material preforms after foaming, preventing problems such as stuffiness from stacking, adhesion, hardening, and deformation from compression. Simultaneously, the combination of a hanging net and buckle structure provides bottom protection, preventing small shoe materials from falling and being damaged. The overall structure has high strength, a neat layout, convenient adjustment, and strong versatility and practicality.

[0015] 2. According to one embodiment of this disclosure, the shoe material preform foaming hanger uses a rotatable rotating rod to link multiple sets of hooks, a clamping rod, and a damping pad to form a dual working area limiting structure. Combined with a mechanical locking mechanism consisting of a telescopic rod, a toggle ring, and meshing teeth, it can accurately achieve three working states: free angle adjustment for hook hanging and picking, static locking to prevent shaking, and rapid unlocking for material unloading. A double closed limiting structure is formed using magnetic grooves, magnetic blocks, elastic buckles, and positioning rods to prevent accidental slippage during shoe material hanging. Furthermore, the pull rod links all the hook bending sections to open and close synchronously, eliminating the need for individual operation and greatly simplifying the material unloading process. This reduces manual labor intensity. The purely mechanical structure is suitable for dusty and humid workshop conditions, is less prone to failure, has a long service life, and effectively improves the quality of shoe material foaming and shaping, as well as the efficiency of mass production.

[0016] 3. According to one embodiment of this disclosure, the shoe material preform foaming rack is equipped with a sliding and adjustable layered crossbeam, a mechanically lockable rotating rod, and an openable and closable three-state hook structure. Combined with magnetic buckle limiting and synchronous linkage material feeding design, it realizes flexible hanging of shoe materials, static anti-shaking shaping, and rapid centralized material feeding, which is suitable for large-scale foaming production and improves product quality and turnover efficiency.

[0027] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0028] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0029] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0030] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0031] like Figure 1-7 As shown, a shoe material preform foaming rack includes a frame 1 and casters 2 installed at the four corners of the bottom of the frame 1. It also includes a crossbeam 3 slidably mounted on the frame 1. A hanging net 4 is fixedly mounted on the crossbeam 3. A buckle 5 for engaging with the cross joint of the hanging net 4 is fixedly mounted on the rear side of the crossbeam 3. There are multiple sets of crossbeams 3. The multiple sets of crossbeams 3 are slidably mounted on the frame 1 through U-shaped frames 7 on both sides. A first limiting hole 8 is opened on the frame 1. A second limiting hole 9 that matches the first limiting hole 8 is opened on the crossbeam 3. When the first limiting hole 8 and the second limiting hole 9 are coaxial, they are locked together by bolts to form an installation area.

[0032] Here, frame 1 serves as the main load-bearing skeleton of the entire hanging rack, providing overall shaping and load-bearing support. It can support the overall weight of multiple sets of crossbeams 3, hanging nets 4, and the entire rack of shoe material blanks. It has high structural strength and is not easily deformed.

[0033] The frame 1 is equipped with four casters 2 at the bottom corners, which enables the entire frame to move freely and turn on the spot. It can be flexibly transferred between the foaming and settling area, the hanging area, and the unloading area, which is suitable for the workshop assembly line turnover operation mode. No manual lifting or auxiliary hoisting is required, and the transfer is convenient and labor-saving.

[0034] The crossbeam 3 is slidably assembled on the frame 1, providing an installation base for the upper suspension structure. The hanging net 4 is laid and fixed on the crossbeam 3, which can provide bottom protection for the space below, preventing small and fragmented shoe material blanks from accidentally falling and being damaged. The buckle 5 is precisely fastened at the cross joint of the hanging net 4, which can lock and limit the hanging net 4 at a fixed point, preventing the hanging net 4 from becoming loose, shifting, or lifting during use, and always maintaining a flat laying state.

[0035] Furthermore, multiple independently set crossbeams 3 are arranged in layers, which can realize the layered and zoned hanging of the shoe material blanks. There is a ventilation gap between the upper and lower layers, which is conducive to the all-round moisture dissipation and ventilation of the shoe material blanks after foaming, and avoids the defects of adhesion and hardening caused by stacking and dampness. The crossbeams 3 rely on the U-shaped frames 7 on both sides to form a sliding guide cooperation with the frame 1. The wrapping and limiting structure of the U-shaped frames 7 can constrain the crossbeams 3 to slide in a straight line along the length of the frame 1, preventing the crossbeams 3 from tilting, deviating, or getting stuck, and ensuring that the multiple sets of crossbeams 3 always maintain parallel and equidistant arrangement, and the overall hanging rack layout is neat and orderly.

[0036] Furthermore, the frame 1 is equipped with a first limiting hole 8, and the crossbeam 3 is equipped with a corresponding second limiting hole 9. The holes are matched one-to-one, and the crossbeam 3 can be freely slid to adjust the spacing according to different styles and sizes of shoe material blanks. After adjustment, bolts are inserted into the coaxial holes to lock and fix it, ensuring reliable positioning and simple disassembly and adjustment. This hole locking structure can adapt to the hanging needs of various specifications of shoe materials, has strong versatility, and the crossbeam 3 will not slide or shake on its own after adjustment. It has good structural stability for long-term use and meets the requirements of batch continuous production.

[0037] A hook 6 for hanging shoe blanks is rotatably mounted on the crossbeam 3. A driving component for rotating the hook 6 is also mounted on the crossbeam 3. The driving component includes rectangular grooves 10 that are linearly and equidistantly opened along the length direction of the crossbeam 3. A through hole 11 is opened on the crossbeam 3 and communicates with the rectangular groove 10. A rotating rod 12 is rotatably connected to the through hole 11 through a bearing. A sleeve is fixedly mounted on one end of the through hole 11 on the crossbeam 3. One end of the rotating rod 12 is rotatably connected to the sleeve through a bearing. There are multiple sets of hooks 6, and each set of hooks 6 is located in a corresponding rectangular groove 10 and is mounted on the rotating rod 12. When the rotating rod 12 rotates, the hook 6 rotates along the axis of the rotating rod 12.

[0038] Here, rotatable hooks 6 are installed on the crossbeam 3, using an independent single-point suspension method to replace the traditional flat stacking, so that each shoe material blank is in a suspended and breathable state, without contact surface compression, thus avoiding quality problems such as deformation, adhesion, and indentation of shoe materials after foaming from the root. A specially equipped drive component is set up to centrally control the angle rotation of the hooks 6, integrating the adjustment structure into the crossbeam 3 itself, eliminating the need for additional external supports. The overall structure has a high degree of integration, occupies little space, and is more convenient for workshop placement, stacking and storage.

[0039] Furthermore, rectangular grooves 10 are linearly and equidistantly opened along the length of the crossbeam 3, which not only provide independent installation space for each set of hooks 6, but also limit the left and right positions of the hooks 6 to prevent them from shifting or deviating. The equidistant layout ensures that the spacing between each hanging point is uniform, the initial shoe material blanks are neatly arranged, the ventilation and convection conditions are consistent, and the overall shoe material shaping and drying degree is uniform, resulting in consistent product quality.

[0040] Furthermore, the crossbeam 3 has a through hole 11 connecting the rectangular groove 10, and the rotating rod 12 is assembled through the bearing. The bearing can greatly reduce the rotational friction resistance, making the rotating rod 12 rotate smoothly and easily without jamming or abnormal noise, reducing mechanical wear caused by long-term reciprocating rotation and extending its service life. One end of the rotating rod 12 rotates with the sleeve of the crossbeam 3 to form double-end support, which distributes the force evenly and is not easy to bend or deform. Multiple sets of hooks 6 are uniformly installed on the rotating rod 12, which can realize one-rod linkage and synchronous angle rotation. There is no need to adjust the angle of each hook 6 individually, which greatly reduces the intensity of manual operation and improves the efficiency of hanging materials and adjusting angles.

[0041] A clamping rod 13 is provided on the crossbeam 3 at the position corresponding to the rectangular groove 10. A fastening groove 14 is provided on the clamping rod 13. A damping pad 15 is covered in the fastening groove 14. When the end of the hook 6 is inserted into the fastening groove 14, a first working area is formed. When the end of the hook 6 is disengaged from the fastening groove 14, a second working area is formed. When in the first working area, the end of the hook 6 abuts against the damping pad 15 to form an anti-slip area.

[0042] Here, the clamping rod 13 is fixedly positioned for each rectangular groove 10, precisely matching the rotation trajectory of each set of hooks 6. It can specifically limit and constrain a single hook 6, with strong structural correspondence, and will not cause limit misalignment or failure. The clamping rod 13 is fixed on the crossbeam 3 as a fixed structure, and its own position does not change. It can be used as a limit reference component for hooks 6 for a long time, with high reliability.

[0043] Furthermore, a recessed locking groove 14 is provided on the clamping rod 13, which adopts the groove embedded limiting method. Compared with the simple baffle limiting, the restraint effect is stronger. It can simultaneously limit the displacement of the end of the hook 6 from the circumference and the side, and prevent the hook 6 from swinging randomly due to the airflow in the workshop, personnel touching it, and the movement of the frame. The locking groove 14 is covered with a damping pad 15. By utilizing the friction damping characteristics of the damping material itself, the contact friction is increased, which can suppress the slight shaking and micro-rotation of the hook 6, and play multiple roles of buffering, anti-slip and shock absorption.

[0044] Furthermore, by inserting or disengaging the end of the hook 6 into the fastening groove 14, two fixed working conditions are defined: a first working area and a second working area. The working conditions are clearly defined and the functions are clearly divided. The first working area is suitable for the static shaping of shoe materials. The damping pad 15 forms an anti-slip zone to firmly lock the posture of the hook 6 and prevent shaking and displacement. The second working area is free from the limit constraint, and the hook 6 can be freely rotated and adjusted to adapt to the manual hanging and unloading operation conditions. The two working states can be switched freely, which fully covers the usage needs of the entire process of hanging, retrieval, static placement and unloading of shoe materials. The structure has extremely strong adaptability.

[0045] A mounting ring 16 is fixedly connected to one side of the crossbeam 3. The inner wall of the mounting ring 16 is provided with a meshing groove 17. The other end of the rotating rod 12 is fixedly installed with a telescopic rod 18 through a placement hole. The movable end of the telescopic rod 18 is fixedly connected with a toggle ring 19. The toggle ring 19 consists of a meshing section and a toggle section. The meshing section has an integrally formed meshing tooth 20 that matches the meshing groove 17. The toggle section is provided with anti-slip knurling 21. When the meshing tooth 20 meshes with the meshing groove 17, the rotating rod 12 is in the locking zone. When the meshing tooth 20 disengages from the meshing groove 17, the rotating rod 12 is in the unlocking zone.

[0046] Here, the mounting ring 16 is fixed to the side of the crossbeam 3, serving as the fixed base for the entire locking mechanism. The lateral arrangement does not occupy the hanging space above the crossbeam 3, nor does it interfere with the normal suspension of the hook 6 and the initial shoe material blank. The layout is reasonable and compact. The mounting ring 16 adopts a fixed connection method, which is stable and reliable as a whole. It will not loosen or shift during operation, ensuring that the locking reference position remains unchanged.

[0047] Furthermore, a telescopic rod 18 is installed at the end of the rotating rod 12. Utilizing the axial telescopic characteristics of the telescopic rod 18, the end actuating ring 19 can be moved back and forth, thereby realizing the rapid engagement or disengagement of the meshing teeth 20 and the meshing groove 17. The purely mechanical telescopic meshing structure does not require electrical control, is suitable for humid and dusty workshop conditions, has a low failure rate, and is easy to maintain. The meshing groove 17 is opened on the inner wall of the mounting ring 16. The inner ring meshing method is uniformly stressed, has a large locking load capacity, and is not prone to slippage or disengagement.

[0048] Furthermore, the toggle ring 19 features a segmented structure design, with the meshing section integrating a specially molded meshing tooth 20. The tooth groove matching accuracy is high, and there is no gap or play after meshing, which can completely lock the rotating rod 12, eliminating any self-rotation and shaking. The toggle section is equipped with anti-slip knurling 21, which increases the friction for hand grip, making it less likely to slip when pushing, pulling, or rotating by hand, and can be easily operated without the aid of tools. The locking and unlocking areas are distinguished by meshing and disengaging. The locking area meets the anti-rotation requirements for long-term static shaping, while the unlocking area meets the requirements for free angle adjustment for hanging and unloading materials. The operation is simple, the locking is reliable, and the adaptability is strong.

[0049] The hook 6 consists of a straight section and a bent section. The straight section is connected to the rotating rod 12. A magnetic groove 22 is provided at the end of the straight section. The magnetic groove 22 is hinged to the end of the bent section through a connecting rod. A magnetic block 23 adapted to the magnetic groove 22 is fixedly installed on the side of the bent section that contacts the inner wall of the magnetic groove 22. When the bent section abuts against the magnetic groove 22, the magnetic block 23 and its inner wall form a magnetic fixing area. An elastic buckle 24 is fixedly connected to the straight section. A positioning rod 25 adapted to the elastic buckle 24 is fixedly connected to the bent section. When the end of the positioning rod 25 is inserted into the elastic buckle 24, a positioning area is formed. The bent sections of multiple sets of hooks 6 are connected by a pull rod 26. When the pull rod 26 is moved, the multiple sets of bent sections rotate along the axis of the connecting rod. An anti-slip sleeve 27 is fixedly connected to the end of the pull rod 26.

[0050] Here, the hook 6 adopts a hinged split structure with a straight section and a bent section, which is different from the traditional fixed whole hook. It has an opening and closing function. Under normal conditions, it is closed to form a closed hanging ring to prevent the shoe material blank from slipping off the hook opening. When unloading, the hook opening can be opened to achieve quick unloading, taking into account both suspension safety and unloading convenience. The straight section is rigidly connected to the rotating rod 12 to ensure that all hooks 6 follow the rotating rod 12 to rotate synchronously, with good angle consistency and a neat and uniform hanging posture for the whole frame.

[0051] Furthermore, a magnetic groove 22 is provided at the end of the straight section, which, together with the magnetic block 23 on the bent section, forms a magnetic fixing area. The magnetic attraction allows the bent section to automatically close and reset in its normal state, eliminating the need for manual closing. The reset is sensitive and reliable, and the magnetic attraction does not involve any hard mechanical impact. The opening and closing process is quiet and smooth, and will not damage the surface of the shoe material. An elastic buckle 24 and a positioning rod 25 are added to form a mechanical positioning area, which, together with the magnetic structure, forms a double safety limit. This can resist the influence of external forces caused by workshop vibration, airflow disturbance, and slight touch, preventing the bent section from accidentally opening on its own and greatly improving the hanging safety.

[0052] Furthermore, the bending sections of multiple hooks 6 are uniformly linked with the pull rod 26, enabling single-point control and simultaneous opening and closing of multiple sets. This eliminates the need to manually bend each hook 6 for material feeding, greatly saving labor time and making it suitable for large-volume centralized material feeding operations. The pull rod 26 is fitted with an anti-slip sleeve 27 at the end, improving grip comfort and surface anti-slip performance. It is less prone to slipping and hand fatigue during long-term continuous operation, demonstrating good ergonomics. The overall structure design, with dual limits of magnetic attraction and mechanical buckle, and synchronized opening and closing, is simple, durable, easy to operate, safe, and reliable, making it fully compatible with the entire process of shoe material preform foaming production.

[0053] The working principle of this utility model is as follows:

[0054] Before operation, the operator first pulls the actuating ring 19 outward to disengage the meshing teeth 20 on the actuating ring 19 from the meshing groove 17 on the inner wall of the mounting ring 16, thus releasing the circumferential locking state of the rotating rod 12. Then, the operator rotates the actuating ring 19 with anti-slip knurling 21 to rotate the rotating rod 12, adjusting the hook 6 to the desired position. Figure 7 The angle of the hook 6 in the hanging working state is shown. At this time, the end of the hook 6 is completely detached from the fastening groove 14 on the clamping rod 13 and does not contact the damping pad 15 inside the fastening groove 14. It is in the second working area. The hook 6 maintains a fixed tilt angle by relying on the assembly damping and will not shake randomly. At the same time, the hook 6 is kept in a closed state by the straight section and the bent section. The magnetic block 23 on the bent section is attracted to the inner wall of the magnetic groove 22 at the end of the straight section. The elastic buckle 24 on the straight section and the positioning rod 25 on the bent section form a fastening and positioning, forming a closed hook 6 structure. In this state, there is no need to operate the pulling rod 26. The operator can directly hang the shoe material blanks on each set of hooks 6 in sequence to complete the hanging and placement of the entire rack of materials.

[0055] After all the initial shoe material blanks have been hung up, proceed to the attached... Figure 5In the locked working state shown, the operator rotates the actuating ring 19 in the opposite direction, causing the rotating rod 12 to rotate synchronously, driving each group of hooks 6 to deflect synchronously, so that the end of the hook 6 is embedded in the corresponding fastening groove 14 of the clamping rod 13, and closely abuts against the damping pad 15 in the fastening groove 14, entering the first working area to form an anti-slip limit; then, the actuating ring 19 is pressed inward, and with the extension and retraction displacement of the telescopic rod 18, the meshing teeth 20 on the actuating ring 19 re-engage and lock with the meshing groove 17 on the inner wall of the mounting ring 16, fixing the rotating rod 12 circumferentially, preventing it from rotating; relying on the anti-slip of the damping pad 15 and the mechanical locking of the meshing teeth 20 and the meshing groove 17, the rotation and shaking of the hook 6 are doubly restricted, the overall angle of the hook 6 is completely fixed, and the pulling rod 26 does not need to be operated throughout the process. The shoe material blank can be foamed and ventilated and shaped in a stable hanging state, avoiding displacement, falling off and deformation caused by workshop airflow, personnel touch, frame movement.

[0056] After the initial foaming and shaping of the shoe material is completed, it will proceed to the next step. Figure 3 In the material feeding operation shown, the operator first pulls the actuating ring 19 outward, causing the telescopic rod 18 to extend, disengaging the meshing teeth 20 from the meshing groove 17 and releasing the locking restriction of the rotating rod 12, allowing the hook 6 to rotate freely to adjust its tilt angle. Subsequently, the operator holds the anti-slip sleeve 27 at the end of the pulling rod 26 and pulls it, causing the bent sections of multiple hooks 6 to rotate synchronously around the hinge point. The bent sections overcome the magnetic attraction between the magnetic block 23 and the magnetic groove 22, simultaneously causing the positioning rod 2... 5. Release the locking limit of the elastic buckle 24 to realize the synchronous opening of the hook opening of all hooks 6, release the restriction on the shoe material blank, and the shoe material blank can be easily removed from the hook 6 to complete the material cutting; after the material cutting is completed, release the pull rod 26, and the bent section will automatically return to its position and close under the magnetic attraction of the magnetic block 23 and the elastic reset action of the elastic buckle 24. The positioning rod 25 will re-lock into the elastic buckle 24, the hook 6 will restore the closed structure, and then the hook 6 will be adjusted back to the initial hanging angle to enter the next round of hanging operation cycle.
