[0025] Referring to the drawings Figures 1-4 , a kind of automatic safety door is shown, the safety door includes door leaf 4, two groups of parallelly arranged cylinder assembly 2, the two groups of cylinder assembly 2 are respectively installed on the both sides of the door leaf 4;Each cylinder assembly 2 includes base 1, cylinder body 20 and drive rod 21, the bottom of the cylinder body 20 is assembled with the base 1, the top of the cylinder body 20 is installed by the drive rod 21 controlled lifting, the upper portion of the door leaf 4 is connected with the drive rod 21, the lower portion of the door leaf 4 is equipped with the guide block 5 matched with the cylinder body 20;The guide block 5 is equipped with the profiled groove matched with the cylinder body 20, the guide block 5 is installed on the cylinder body 20 via the profiled groove and can be lifted and moved.

[0026] The two groups of cylinder assemblies 2 are respectively installed on both sides of the door leaf 4, and the automatic installation door is fixed to the ground by the base 1 of each cylinder assembly 2. The fixing mode of the base 1 to the ground is not limited, for example, the conventional mode of being nailed into a pin shaft can be adopted, and the base 1 and the cylinder body 20 can be fixed by bolts and the like. The cylinder body 20 controls the up-down movement of the driving rod 21, and the upper part of the door leaf 4 is fixed on the driving rod 21, which synchronously rises and falls with the driving rod 21, while the lower part of the door leaf 4 is in sliding cooperation with the cylinder body 20 through the guide block 5. The guide block 5 is provided with a profiling groove which is matched with the peripheral contour of the cylinder body 20, and the cylinder body 20 is sleeved in the profiling groove. When the door leaf 4 rises and falls with the driving rod 21, the guide block 5 synchronously rises and falls along the cylinder body 20, thereby enhancing the stability of the rising and falling action of the door leaf 4. Therefore, the guide block 5 of the automatic safety door runs along the cylinder body 20, so that the cylinder body 20 plays a role of guide rail, thereby simplifying the structure of the automatic safety door, reducing the parts, facilitating disassembly, maintenance and cost reduction.

[0027] Specifically, referring to the drawings, Figure 4 The cross section of the profiling groove of the guide block 5 is in U shape, so that one side of the profiling groove forms a notch, through which the guide block 5 is sleeved on the cylinder body 20 and rises and falls along the cylinder body 20. The cylinder assembly 2 can adopt a magnetic ring cylinder. In order to know the rising and falling height of the magnetic ring cylinder, a magnetic ring inductor 7 can be configured for the magnetic ring cylinder, and the magnetic ring inductor 7 can be installed on the cylinder body 20. Specifically, referring to the drawings, Figures 3-4 The depth of the profiling groove of the guide block 5 is less than the width of the cylinder body 20. After the guide block 5 is sleeved on the cylinder body 20, there is still a surplus space on one side of the cylinder body 20. The magnetic ring inductor 7 is installed at the surplus space of the cylinder body 20, and the rising and falling position of the cylinder assembly 2 is known by sensing the position of the guide block 5.

[0029] In some embodiments, the door leaf 4 comprises a mesh 40 and a frame 41 which is arranged at the periphery of the mesh 40. The mesh 40 structure is adopted for the main part of the door leaf 4, which is beneficial to weight reduction and cost saving, and the peripheral frame 41 can enhance the strength and stability of the door leaf 4.

[0030] In some embodiments, the door leaf 4 is connected with the driving rod 21 through a connecting block 3, one end of the connecting block 3 is fixed on the top of the driving rod 21, and the other end of the connecting block 3 is fixed on the top of the frame 41. The connecting block 3 can be generally square-shaped, one end of the connecting block 3 is provided with a through hole matched with the driving rod 21, the driving rod 21 is inserted into the through hole, and a structure or a component for positioning or the like can be arranged between the driving rod 21 and the connecting block 3, for example, the two can be fixed by bolts. Similarly, the other end of the connecting block 3 can also be locked on the top of the frame 41 by bolts, so as to realize the stable lifting action of the driving rod 21 controlling the door leaf 4.

[0031] In some embodiments, the cylinder assembly 2 is provided with a speed regulating valve 6 for regulating the lifting speed of the cylinder assembly 2, and a position reversing valve (not shown) for regulating the lifting direction of the cylinder assembly 2 at any time.

[0032] The automatic safety door is fixedly installed at the material docking interface through the base 1. The automatic installation door is fixed on the ground by the base 1, and the opening and closing of the material docking interface is controlled by the lifting of the door leaf 4, so as to avoid personnel from entering by mistake and improve the safety of the flow line.

[0033] In summary, the improved automatic safety door does not need to increase a guide rail, directly uses a cylinder as a guide device, and cooperates with the designed profiling guide block 5, so as to reduce the number of parts, reduce the structural complexity, and reduce the installation workload. The overall safety door is directly fixed on the ground by the cylinder base 1, does not need to rely on an external support or equipment, forms an overall assembly, is convenient to disassemble, install and package and ship, the overall structure is simplified, the number of parts is reduced, the operation stability of the equipment is improved, and the maintenance cost and difficulty in the later period are reduced.
