[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] The present invention will now be further described with reference to the accompanying drawings.

[0024] This utility model provides the following technical solution:

[0025] As attached Figure 1-5 As shown, this utility model discloses a grid swing mechanism for shoe drying equipment, including a positioning bracket 1, several swing grids 2, and a grid transmission device 3. The swing grids 2 are swingably mounted on the positioning bracket 1, and the grid transmission device 3 is connected to the swing grids 2, driving the swing grids 2 to swing on the positioning bracket 1. Specifically, in this design, the positioning bracket 1 is fixed inside the heating chamber of the shoe drying equipment (not shown). The heating chamber has a conveyor belt, and the positioning bracket 1 is fixed inside the heating chamber at the lower part of the conveyor belt. The swing grids 2 are mounted on top of the positioning bracket 1, and the grid transmission device is installed outside the shoe drying equipment and extends into the heating chamber through a bracket connector 21 to connect with the positioning bracket 1, thereby driving the swing grids 2 on the positioning bracket 1 to swing. There is a certain gap between adjacent swing grids 2, allowing hot air to circulate between the grids, thus evenly drying the shoes inside the shoe machine. The swing frequency and amplitude of the grid swing mechanism can be adjusted according to different shoe types and drying requirements to ensure optimal drying effect.

[0026] Furthermore, the swing grille 2 is vertically mounted on the positioning bracket 1, and the grille transmission device 3 drives the swing grille 2 to swing on the positioning bracket 1. The swing angle of the swing grille 2 is ±45°. Specifically, in this embodiment, in the initial state, the swing grille 2 and the lower frame 5 of the positioning bracket 1 are in a vertical structure. When the swing grille 2 begins to swing under the action of the transmission device, its swing angle can reach ±45°. The advantage of this design is that it can more effectively promote the convection of hot air inside the shoe machine, ensuring that each pair of shoes is heated evenly. In addition, the adjustability of the swing angle also provides flexibility to adapt to different shoe types and drying needs. In actual operation, the operator can adjust the swing angle of the swing grille 2 by adjusting the transmission device according to the specific working state and drying effect of the shoe machine, thereby achieving the best drying effect. This design not only improves drying efficiency but also extends the service life of the equipment and reduces energy consumption.

[0027] Furthermore, the positioning bracket 1 includes an upper frame 4 and a lower frame 5. The swing grid 2 is swingably mounted on the lower frame 5, and the side of the swing grid 2 away from the lower frame 5 is fixedly connected to the upper frame 4. One end of the grid transmission device is connected to the upper frame 4 and drives the swing grid 2 to swing through the upper frame 4. Specifically, in this embodiment, the lower frame 5 is used to support and position the swing grid 2, while the upper frame 4 plays a transmission role. The upper frame 4 transmits the power generated by the grid transmission device 3 to the swing grid 2, enabling the swing grid 2 to swing stably and evenly under the support of the lower frame 5. The structural design of the upper frame 4 and the lower frame 5 not only ensures the overall stability but also facilitates maintenance and adjustment.

[0028] Furthermore, the lower frame 5 includes two symmetrically arranged swing connecting frames 6 and several support frames 7 arranged between the swing connecting frames 6. A frame connecting rod 8 is provided between the swing connecting frames 6 and the support frames 7 and is connected through the frame connecting rod 8. Swing grooves 9 are formed on the swing connecting frames 6. Swing ends 10 protrude from both sides of the bottom end of the swing grid 2 corresponding to the swing grooves 9, and the swing ends 10 extend into the corresponding swing grooves 9 and swing with the swing connecting frames 6. The bottom of the swing grid 2 is connected to the support frames 7. Specifically, in this embodiment, the design of the swing connecting frames 6 ensures the stability and flexibility of the swing grid 2 during movement, while the support frames 7 provide a solid support foundation for the entire structure. The use of the frame connecting rod 8 not only enhances the connection strength between the swing connecting frames 6, but also allows the entire lower frame 5 to maintain good integrity when subjected to external forces. The ingenious cooperation between the swing grooves 9 and the swing ends 10 allows the swing grid 2 to be accurately positioned during swinging, avoiding the situation where the drying effect is affected by excessive or insufficient swing amplitude. Furthermore, the direct contact between the bottom of the swing grid 2 and the support frame 7 further enhances the structural stability and ensures the reliability of the equipment during long-term operation. Through this meticulous design, the equipment not only achieves efficient drying but also maintains good performance in complex working environments. During the swinging process of the swing grid 2, the rotational motion centered on the swing end 10 effectively distributes the material evenly, avoiding localized overheating or uneven drying. Simultaneously, the symmetrical arrangement of the swing connecting frame 6 ensures the balance of the swing grid 2 during the swinging process, reducing additional vibration and noise caused by imbalance. The clearance fit between the swing end 10 and the swing groove 9 prevents wear and unnecessary interference during the swinging process, thereby extending the service life of the equipment.

[0029] Furthermore, the upper frame 4 includes two symmetrically arranged transmission connecting plates 11. Transmission grooves 12 are formed on the transmission connecting plates 11. A transmission end 13 protrudes from the swing grid 2 corresponding to the transmission groove 12, extending into the transmission groove 12 and connecting to the corresponding transmission connecting plate 11. A plate connecting member 14 is provided between the two transmission connecting plates 11, and the plates are connected via the plate connecting member 14. A transmission member 15 is provided on the plate connecting member 14, with one end of the transmission member 15 connected to the grid transmission device 3. Specifically, in this embodiment, the transmission end 13 and the transmission groove 12 are tightly fitted. This tight fit design ensures smoother movement of the transmission end 13 within the transmission groove 12, reducing friction and wear, and extending the service life of the equipment. The connection between the transmission member 15 and the grid transmission device 3 via the plate connecting member 14 ensures uniform transmission of the transmission force, making the movement of the swing grid 2 more precise and efficient. Furthermore, the symmetrically arranged transmission connecting plates 11 not only enhance the structural stability of the upper frame 4 but also ensure the symmetry of the transmission system, further improving the overall operational stability of the equipment. The design of the plate connecting parts 14 also takes into account the convenience of maintenance and replacement, facilitating quick disassembly and installation during equipment maintenance and reducing maintenance costs.

[0030] Furthermore, the grid transmission device includes a power source 16 and a power transmission assembly 17. The two ends of the power transmission assembly 17 are connected to the swing grid 2 and the power source 16, respectively. The power source 16 drives the power transmission assembly 17 to reciprocate, and the power transmission assembly 17 drives the swing grid 2 to swing during its movement. Specifically, in this embodiment, the power source 16 can be a cylinder, motor, or hydraulic device, etc., and the appropriate type of power source 16 is selected according to the actual application scenario. The power transmission assembly 17 is made of highly wear-resistant materials to ensure stability and reliability during long-term operation. Through a precise control system, the power source 16 can achieve precise displacement of the power transmission assembly 17, thereby ensuring that the movement amplitude and frequency of the swing grid 2 meet the preset requirements. In addition, the design of the power transmission assembly 17 can efficiently convert the kinetic energy of the power source 16 into the mechanical energy of the swing grid 2, reducing energy loss and improving overall working efficiency. The construction of the power transmission assembly 17 also considers fatigue resistance, ensuring excellent performance even during long-term, high-frequency operation. The connection between the power source 16 and the transmission assembly is a separate connection, which greatly facilitates daily maintenance and replacement work and further improves the availability of the equipment.

[0031] Furthermore, the power transmission assembly 17 includes an eccentric transmission block 18, a transmission connecting rod 19, a guide seat 20, and a bracket connector 21. The power source 16 is a motor, and the power source 16 has an output shaft 22. The eccentric transmission block 18 has a shaft connection hole 23 coaxially arranged with the output shaft 22 and a transmission connection hole 24 located on the side away from the shaft connection hole 23. The output shaft 22 extends into the shaft connection hole 23 and connects to the power source 16. One end of the transmission connecting rod 19 extends into the transmission connection hole 24 and connects to the eccentric transmission block 18. A guide groove 25 is formed in the guide seat 20, and a guide slide rod 26 is arranged in the guide groove 25. The guide slide rod 26 passes through the guide groove 25. One end of the guide slide rod 26 extends into the transmission connection hole 24 and connects to the transmission connecting rod 19. The other end of the guide slide rod 26 is connected to the bracket connector 21, and the end of the bracket connector 21 away from the guide slide rod 26 is connected to the transmission component 15. Specifically, in this embodiment, the power source 16 is a servo motor. The output shaft 22 of the servo motor extends into the shaft connection hole 23 of the eccentric transmission block 18, driving the eccentric transmission block 18 to rotate. During rotation, the eccentric transmission block 18 drives the transmission connecting rod 19 to reciprocate through the transmission connection hole 24. The other end of the transmission connecting rod 19 is connected to the guide slide rod 26, allowing the guide slide rod 26 to slide within the guide groove 25, thereby achieving precise linear motion. The bracket connector 21 transmits this linear motion to the transmission component 15, which then transmits it to the upper frame 4, enabling the swinging grille 2 connected to the upper frame 4 to reciprocate on the lower frame 5, ensuring the stability and efficiency of the entire transmission system. Furthermore, the precise control function of the servo motor makes the transmission process smoother, reduces mechanical wear, and extends the service life of the equipment. The design of the guide seat 20 not only ensures the motion accuracy of the guide slide rod 26 but also plays a role in shock absorption and noise reduction, improving the overall operating quality of the equipment.

[0032] Furthermore, the transmission connecting rod 19 has two symmetrically arranged connecting ends 27, each with a bearing hole 28. A corresponding bearing is installed within each bearing hole 28. A first rotating connecting shaft 29 is provided between the transmission connecting rod 19 and the eccentric transmission block 18. Both ends of the first rotating connecting shaft 29 extend into the transmission connecting hole 24 and the corresponding bearing hole 28, respectively. A second rotating connecting shaft 30 is provided between the transmission connecting rod 19 and the guide slide rod 26. The guide slide rod 26 has a slide rod connecting hole 31, and both ends of the second rotating connecting shaft 30 extend into the corresponding bearing hole 28 and the slide rod connecting hole 31, respectively. Specifically, in this embodiment, the bearings within the bearing holes 28 enable the transmission connecting rod 19 to rotate flexibly around the first rotating connecting shaft 29 during motor rotation, thereby effectively reducing frictional resistance during transmission and extending the service life of the equipment. The first rotating connecting shaft 29 and the second rotating connecting shaft 30 are fixed by nuts after passing through the corresponding bearing holes 28, ensuring that the connecting shafts will not loosen or fall off when running at high speed, thus further improving the reliability and safety of the transmission system.

[0033] Furthermore, the transmission connecting rod 19 is configured with a split structure, comprising an intermediate connecting rod 32 and connecting blocks 33 disposed at both ends of the intermediate connecting rod 32. The connecting blocks 33 are threadedly connected to the intermediate connecting rod 32, and the connecting end 27 is disposed on the corresponding connecting block 33. A locking nut 34 is disposed between the connecting block 33 and the intermediate connecting rod 32. Specifically, in this embodiment, the intermediate connecting rod 32 is made of high-strength alloy material to ensure its stability and durability in high-intensity working environments. The design of the locking nut 34 further enhances the stability of the connection. This split structure design not only facilitates installation and maintenance but also effectively reduces wear caused by long-term use, extending the service life of the equipment. In addition, the design of the connecting block 33 allows for quick replacement, greatly improving the maintenance efficiency of the equipment.

[0034] Furthermore, the bracket connector 21 is located on the end of the guide slide rod 26 away from the transmission connecting rod. The bracket connector 21 extends towards the swing grille 2 and connects to the transmission component 15. Specifically, in this embodiment, the structure of the transmission component 15 is the same as that of the transmission connecting rod 19. The transmission component 15 also adopts a split design, including a middle connecting rod 32 and connecting blocks 33 at both ends, which are fixed by threaded connection and locking nuts 34. One end of the transmission component 15 is connected to the bracket connector 21, and the other end of the transmission component 15 is connected to the plate connecting component 14 after rotation. The two ends of the transmission component 15 are vertical after rotation at one end. This design allows the transmission component 15 to be flexibly adjusted within a multi-angle range to adapt to different working requirements. The connection between the transmission component 15 and the bracket connector 21 is fixed with high-strength bolts to ensure stability during high-speed operation.
