[0002] In the process of realizing this utility model, the inventors discovered that the prior art has at least the following problems:

[0003] The existing heating element lifting structure in the hot bending glass forming section uses a conventional motor + steel wire + pulley system. During production, jamming and detachment from the groove frequently occur. Due to structural limitations, the heating element relies on its own weight to descend, resulting in a slow descent speed. The descent position is also inaccurate due to the reliance on an encoder, which severely affects the glass forming speed and further impacts the overall production cycle.

The lower heating wire mechanism 33 is located near the middle of the upper frame 32, and the middle heating wire mechanisms 34 are located on both sides of the upper frame 32, arranged evenly and reliably. During production, the lifting mechanism changes from passive to active lifting, no longer relying on the heating wires' own gravity for descent. Instead, a servo motor drives the heating wires to descend, with the descent distance precisely controlled by the servo motor. The structure is simple, with a low failure rate, and the heating wires descend and rise quickly, saving time in the mechanism after glass forming and further improving production cycle time.

[0025] The lower heating wire mechanism 33 has a slide module 332, which is mounted on the upper frame 32. A lower heating wire mounting bracket 331 is provided on the slider of the slide module 332, and the lower heating wire is mounted on the lower heating wire mounting bracket 331. The sliding module 332 drives the heating wire to descend, and the descent distance is precisely controlled by a servo motor. The mechanism features a simple structure, low failure rate, and fast descent and ascent speeds, saving time on the mechanism after glass forming and further improving production cycle time.

[0026] The heating element mechanism 34 has an electric cylinder 342 and a heating element mounting bracket 341 connected to the telescopic rod of the electric cylinder 342; the heating element is mounted on the heating element mounting bracket 341. It drives the heating element to descend, and the descent distance is precisely controlled. The structure is simple, the failure rate is low, and the descent and ascent speeds of the heating element are fast, saving the operating time of the mechanism after glass forming and further improving the production cycle.

[0027] The slide module 332 is driven by a servo motor. The descent distance is precisely controlled by the servo motor, resulting in a simple structure, low failure rate, and fast furnace wire descent and ascent speeds, saving the operating time of the mechanism after glass forming and further improving production cycle time.

[0028] The upper frame 32 has three sets of slide modules 332 in the width direction. The sliders of the three sets of slide modules 332 are all connected to the lower furnace wire mounting bracket 331, making the movement process more stable and reliable.

[0029] The central heating wire mechanism 34 also includes an auxiliary slide module, which is mounted on the upper frame 32. The slider of the auxiliary slide module is connected to the central heating wire mounting bracket 341, making the movement process more stable and reliable.

[0030] With the above structure, the passive lifting is changed to active lifting during production. The heating element does not rely on its own gravity to descend. Instead, a servo motor drives the heating element to descend, and the descent distance is precisely controlled by the servo motor. The structure is simple, the failure rate is low, and the heating element descends and rises quickly, saving the running time of the mechanism after glass forming and further improving the production cycle.
