Description

Technical Field

[0001] The utility model relates to the technical field of stacking door rolling, in particular to a rolling mechanism for stacking doors. Background Art

[0002] Soft curtain stacking doors have many functions such as heat preservation, cold preservation, insect prevention, windproof, dust prevention, sound insulation, fire prevention, odor prevention and lighting, and are widely used in food, chemical, textile, refrigeration, electronics, printing, supermarket refrigeration assembly, precision machinery, logistics warehousing and other places. They are suitable for logistics channels, large-area openings, internal and external doors with high windproof requirements, which can improve the requirements of high-performance logistics and clean places, save energy, improve air-conditioning effects, close automatically at high speed, and improve working efficiency. The current stacking door winding mechanism cannot be adjusted up and down.

[0003] The existing patent (publication number: CN214424381U) proposes a quick stacking door that is easy to roll up, which is characterized by including a support rod, a fixed rod, a hanging belt, a reflective strip, a warning light, a circular wind-resistant shaft, a slider, a rolling mechanism, a door curtain, a visual window, and an annular sleeve; when the wind blows the stacking door curtain, the slider cannot swing on the circular wind-resistant shaft, and the circular wind-resistant shaft cannot swing in the slot, which ensures the stability of the stacking door curtain and improves the wind-resistant effect of the stacking door curtain.

[0004] The above-mentioned winding mechanism adopts the technical solution of rolling up the stacking door so that the slider cannot swing on the circular wind-resistant shaft, and the circular wind-resistant shaft cannot swing in the slot, thereby ensuring the stability of the stacking door curtain and improving the wind-resistant effect of the stacking door curtain. The problem with the above-mentioned solution is that when the winding mechanism fails, it is impossible to open the closed flexible stacking door or close the opened flexible stacking door in the first time. Therefore, we propose a winding mechanism for the stacking door to solve the above problem. Utility Model Content
