DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] The present invention will be further described below in conjunction with the accompanying drawings.

[0019] The present invention provides the following technical solutions: As attached Figure 1-5As shown, the present invention discloses a grille swing mechanism applied to a shoe drying machine, comprising a positioning bracket 1, a plurality of swing grilles 2 and a grille transmission device 3, wherein the swing grilles 2 are swingably arranged on the positioning bracket 1, and the grille transmission device 3 is connected to the swing grilles 2 to drive the swing grilles 2 to swing on the positioning bracket 1. Specifically, in the present design, the positioning bracket 1 is fixed in a heating chamber of the shoe drying machine (not shown), and the heating chamber has a conveyor belt, the positioning bracket 1 is fixed in the heating chamber at a position below the conveyor belt, the swing grilles 2 are arranged on the top of the positioning bracket 1, and the grille transmission device is installed outside the shoe drying machine, and extends into the heating chamber through a bracket connector 21 to connect with the positioning bracket 1, thereby driving the swing grilles 2 on the positioning bracket 1 to swing, and there is a certain gap between adjacent swing grilles 2, so that hot air can flow between the grilles, thereby uniformly drying the shoes in the shoe machine. The swing frequency and amplitude of the grille swing mechanism can be adjusted according to different shoe types and drying requirements to ensure the optimization of the drying effect.

[0020] Furthermore, the swing grille 2 is vertically arranged on the positioning bracket 1, and the grille transmission device 3 drives the swing grille 2 to swing on the positioning bracket 1, and the swing angle of the swing grille 2 is ±45°. Specifically, in this embodiment, in the initial state, the swing grille 2 is in a vertical structure with the lower frame 5 of the positioning bracket 1. When the swing grille 2 starts 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 can be heated evenly. In addition, the adjustability of the swing angle also provides flexibility to adapt to different shoe types and drying requirements. In actual operation, the operator can change 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, so as to achieve the best drying effect. This design not only improves the drying efficiency, but also extends the service life of the equipment and reduces energy consumption.

[0021] Furthermore, the positioning bracket 1 includes an upper frame 4 and a lower frame 5, the swing grille 2 is swingably arranged on the lower frame 5, the side of the swing grille 2 away from the lower frame 5 is fixedly connected to the upper frame 4, and one end of the grille transmission device is connected to the upper frame 4 and drives the swing grille 2 to swing through the upper frame 4. Specifically, in this embodiment, the lower frame 5 is used to support and position the swing grille 2, and the upper frame 4 plays a transmission role. The upper frame 4 transmits the power generated by the grille transmission device 3 to the swing grille 2, so that the swing grille 2 can 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.

[0022] Further, the lower frame 5 includes two symmetrically arranged swing connection frames 6 and a plurality of support frames 7 arranged between the swing connection frames 6, a frame connecting rod 8 is arranged between the swing connection frames 6 and the support frames 7 and connected by the frame connecting rod 8, a swing groove 9 is provided on the swing connection frame 6, and the swing ends 10 are formed corresponding to the swing grooves 9 on both sides of the bottom of the swing grille 2, and the swing ends 10 extend into the corresponding swing grooves 9 and swing-connect with the swing connection frames 6, and the bottom of the swing grille 2 is connected with the support frames 7. Specifically, in this embodiment, the design of the swing connection frame 6 ensures the stability and flexibility of the swing grille 2 during the movement, and 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 connection frames 6, but also enables the entire lower frame 5 to maintain good integrity when subjected to external forces. The ingenious cooperation between the swing groove 9 and the swing end 10 enables the swing grille 2 to be accurately positioned during the swinging process, avoiding the situation where the drying effect is affected by the swing amplitude being too large or too small. In addition, the direct contact between the bottom of the swinging grille 2 and the support frame 7 further enhances the stability of the structure and ensures the reliability of the equipment during long-term operation. Through this refined design, the equipment can not only achieve efficient drying effects, but also maintain good performance in complex working environments. During the swinging of the swinging grille 2, the rotational motion centered on the swinging end 10 can effectively distribute the material evenly and avoid local overheating or uneven drying. At the same time, the symmetrical setting of the swinging connecting frame 6 ensures the balance of the swinging grille 2 during the swinging process and reduces the additional vibration and noise caused by imbalance. The clearance fit between the swinging end 10 and the swinging slot 9 can prevent wear and unnecessary interference during the swinging process, thereby extending the service life of the equipment.

[0023] Further, the upper frame 4 includes two symmetrically arranged transmission connecting plates 11, a transmission groove 12 is provided on the transmission connecting plates 11, and a transmission end 13 is protruded corresponding to the transmission groove 12 on the swing grille 2, and the transmission end 13 extends into the transmission groove 12 and is connected to the corresponding transmission connecting plate 11, a plate body connecting member 14 is provided between the two transmission connecting plates 11 and connected through the plate body connecting member 14, and a transmission member 15 is provided on the plate body connecting member 14, and one end of the transmission member 15 is connected to the grille transmission device 3.

Through this tightly fitting design, the movement of the transmission end 13 in the transmission groove 12 is smoother, friction and wear are reduced, and the service life of the equipment is extended. The transmission member 15 is connected to the grille transmission device 3 through the plate body connecting member 14, which ensures the uniform transmission of the transmission force, making the movement of the swing grille 2 more accurate and efficient. In addition, the symmetrically arranged transmission connecting plate 11 not only enhances the structural stability of the upper frame 4, but also ensures the symmetry of the transmission system, further improving the overall running stability of the equipment. The design of the plate connecting member 14 also takes into account the convenience of maintenance and replacement, which is convenient for quick disassembly and installation during equipment maintenance, reducing maintenance costs.

[0024] Further, the grille transmission device includes a power source 16 and a power transmission component 17, the two ends of the power transmission component 17 are respectively connected to the swing grille 2 and the power source 16, the power source 16 drives the power transmission component 17 to move back and forth, and the power transmission component 17 drives the swing grille 2 to swing during the movement. Specifically, in this embodiment, the power source 16 can be a cylinder, a motor or a hydraulic device, etc., and the appropriate type of power source 16 is selected according to the actual application scenario. The power transmission component 17 is made of highly wear-resistant materials to ensure the stability and reliability of long-term operation. Through a precise control system, the power source 16 can achieve precise displacement of the power transmission component 17, thereby ensuring that the movement amplitude and frequency of the swing grille 2 meet the preset requirements. In addition, the design of the power transmission component 17 can efficiently convert the kinetic energy of the power source 16 into the mechanical energy of the swing grille 2, reducing energy loss and improving overall work efficiency. The structure of the power transmission component 17 also takes into account fatigue resistance to ensure that excellent performance is maintained in long-term high-frequency operation. The connection between the power source 16 and the transmission assembly adopts a split connection, which greatly facilitates daily maintenance and replacement work and further improves the availability of the equipment.

Specifically, in this embodiment, the power source 16 is a servo motor, and the output shaft 22 of the servo motor extends into the shaft connection hole 23 of the eccentric transmission block 18 to drive the eccentric transmission block 18 to rotate. During the rotation process, 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 26, so that the guide slide 26 slides in the guide groove 25, thereby achieving precise linear motion. The bracket connecting member 21 transmits this linear motion to the transmission member 15, and then the transmission member 15 transmits it to the upper frame 4, so that the swing grille 2 connected to the upper frame 4 can reciprocate on the lower frame 5, ensuring the stability and efficiency of the entire transmission system. In addition, the precise control function of the servo motor makes the transmission process more stable, reduces mechanical wear, and prolongs the service life of the equipment. The design of the guide seat 20 not only ensures the movement accuracy of the guide slide 26, but also plays a role in shock absorption and noise reduction, thereby improving the operation quality of the overall equipment.
