Retractable belt machine

Abstract

The invention discloses a retractable belt machine. A retractable rack is slidingly connected to a machine base, a retractable driving mechanism is installed on the machine base and drives a sliding rack so that the sliding rack can extend and retract in the transmission direction of a conveying belt, and the conveying belt is in tensioning to the machine base and the retractable rack at the sametime. A belt driving mechanism drives the conveying belt to move; when a firefighting door needs to be closed, the retractable rack retracts to provide the position for the firefighting door, the speed of linear movement is high, the movement journey is short, and evacuation can be completely in time, so that the firefighting door falls down; since the conveying belt is in a tensioning state, theconveying belt cannot be damaged.

Description

technical field [0001] The invention belongs to the technical field of logistics equipment, in particular to a telescopic conveyor belt. Background technique [0002] With the rapid development of my country's logistics industry, the existing traditional manual sorting lines are gradually being replaced by automated logistics sorting lines due to the disadvantages of high cost and low efficiency. From the current analysis, affected by the rapid development of e-commerce and other factors, logistics companies transport more and more goods every day. The frequency of cargo loading errors during logistics sorting is getting higher and higher; [0003] The automatic logistics sorting and conveying system must be identified and sorted through a very long conveyor belt. However, because the fire protection regulations limit the area of ​​the workshop fire zone, the logistics transmission system will inevitably produce multiple areas when used in conjunction. The opening and clos...

Problems solved by technology

[0003] The automatic logistics sorting and conveying system must be identified and sorted through a very long conveyor belt. However, because the fire protection regulations limit the area of ​​the workshop fire zone, the logistics transmission system will inevitably produce multiple areas when used in conjunction. The opening and closing methods of the fire doors in the fire zone are basically sliding up and down. The fire doors are usually open. The transmission line will pass through the fire door openings to connect several fire areas. When the fire doors need to be closed , it is necessary to evacuate the conveying line in the fire door opening, so that the fire door can be dropped and closed. In the prior art, the evacuation of the conveying line body is carried out manually, and the flip type is adopted. Manual transfer cannot be completed in time, and the flip type Because it has to be flipped 90 degrees to complete the evacuation, it takes a long time to wait for the evacuation of the conveyor line, and if the evacuation is not timely, it may cause serious consequences; It can be turned over smoothly, and a part of the guard plate at the intersection of the two has to be cut off to realize the flip, but the cut guard plate will cause the goods to fall, so there are great disadvantages
