[0002] With the continuous improvement of the automation level of the logistics industry, automated logistics sorting and conveying systems have been widely used in the multi-layer layout between factories. In order to meet the requirements of fire regulations, fire shutter doors must be installed in factory rooms to ensure that they can be quickly closed in an emergency to achieve regional isolation. To this end, telescopic belt conveyors have been introduced in the prior art, which enable the conveyor line to quickly move out of the fire door opening when the fire door is closed to ensure the continuity of logistics. However, the existing telescopic belt conveyor uses a motor with a two-stage transmission sprocket chain as the drive system, which increases the size and height of the equipment, which limits the overall compactness of the equipment, making it difficult for the lower layer of the line to reach the required elevation when the multi-layer conveyor line passes through the fire door opening.

[0003] The existing telescopic belt conveyor has a technical problem that it is difficult for the lower layer of the multi-layer conveyor line to reach the required elevation when the multi-layer conveyor line passes through the fire door opening due to the limitation of the two-stage transmission drive system of the motor and the sprocket chain, which increases the size and height of the equipment and limits the overall compactness. Summary of the invention

[0038] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. 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.

[0039] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0040] The existing telescopic belt conveyor has a technical problem that it is difficult for the lower layer of the multi-layer conveyor line to reach the required elevation when the multi-layer conveyor line passes through the fire door opening due to the limitation of the two-stage transmission drive system of the motor and the sprocket chain, which increases the size and height of the equipment and limits the overall compactness.

[0041] In view of this, the present invention provides a compact telescopic belt conveyor, comprising:

[0042] The frame 100, the conveyor belt 200, the driving mechanism 300 and the telescopic mechanism 400. The frame 100 includes a fixed frame 110 and a telescopic frame 120. The telescopic mechanism 400 includes a synchronous pulley set 410. The synchronous pulley set 410 is connected to the telescopic frame 120 by power and is used to drive the telescopic frame 120 to slide on the fixed frame 110. The driving mechanism 300 includes an electric roller 310 and an end roller 320. The electric roller 310 is installed on the fixed frame 110, and the end roller 320 is rotatably installed on the telescopic frame 120. The conveyor belt 200 surrounds and is tensioned on the electric roller 310 and the end roller 320 to form a closed loop. The length of the conveyor belt 200 in the transmission direction changes with the relative sliding of the fixed frame 110 and the telescopic frame 120. The rotation of the electric roller 310 can directly drive the conveyor belt 200.

[0043] Based on the above technical solutions, the compact telescopic belt conveyor provided by the present invention can achieve the following technical effects:

[0044] The compact telescopic belt conveyor adopts the primary transmission system of the electric roller 310 to directly drive the conveyor belt 200, and drives the telescopic frame 120 to extend and retract through the transmission structure of the motor and the synchronous pulley group 410, so that the overall structure of the equipment is compact and the telescopic process is more stable. It overcomes the technical problem that the existing telescopic belt conveyor is limited by the secondary transmission drive system of the motor and the sprocket chain, which increases the size and height of the equipment, limits the overall compactness, and makes it difficult for the lower layer of the multi-layer conveyor line to reach the required elevation when the multi-layer conveyor line passes through the fire door.

Among them, the third tensioning unit 333 includes a first tensioning screw and a plug-in board. The plug-in board is installed on the fixed frame 110. The first tensioning screw is inserted into the plug-in board and is threadedly connected to the first tensioning roller 331, which is used to adjust the position of the first tensioning roller 331 to cooperate with the first redirecting roller 332 to tension the conveyor belt 200.

[0059] In the solution of this embodiment, the driving mechanism 300 also includes a third redirecting roller 350, which is installed on the telescopic frame 120 and is used to adjust the movement path of the conveyor belt 200 to avoid interference between the telescopic frame 120 and the conveyor belt 200 during the sliding process.

[0060] In order to improve the sliding stability of the telescopic frame 120 relative to the fixed frame 110, in the solution of this embodiment, the frame 100 also includes a sliding guide assembly 130, and the sliding guide assembly 130 includes a C-type roller guide 131 and a guide wheel 132. One end of the C-type roller guide 131 is installed on the fixed frame 110, and the other end is installed on the telescopic frame 120, and it is extended or shortened with the relative sliding of the fixed frame 110 and the telescopic frame 120.

When the first photoelectric detection group 441 and the second photoelectric detection group 442 fail, the contact between the limit block and the roller can ensure that the roller group will not slide out of the range of the C-type guide rail. The C-type roller guide rail 131 is not only convenient for compressing the volume of the equipment, but also ensures the smoothness of the telescopic process.

[0061] In order to prevent the goods from falling off the side of the conveyor belt 200 during transportation, in the solution of this embodiment, the frame 100 also includes a fence assembly 140, and the fence assembly 140 includes a fixed guard plate 141 and a telescopic guard plate 142.

The length of the continuous guardrail in the transmission direction of the conveyor belt 200 changes with the relative sliding of the fixed frame 110 and the telescopic frame 120.

[0062] In summary, the specific working process of the compact telescopic belt conveyor provided in this embodiment is as follows:

[0063] The compact telescopic belt conveyor is installed at the fire shutter door and connected between the conveying lines at both ends of the fire shutter door. At this time, the telescopic frame 120 extends out of the fixed frame 110 and is located in the projection area of ​​the fire shutter door.

The rotation of the electric roller 310 directly drives the conveyor belt 200 to operate, realizing the conveying function. The secondary transmission system of the chain sprocket is simplified, making the overall structure of the compact telescopic belt conveyor compact.

[0065] When the fire rolling shutter door needs to be closed, the electric drum 310 stops, and the servo motor 421 is started to drive the telescopic frame 120 to slide toward the side of the fixed frame 110 through the first synchronous belt 414, the second synchronous belt 415 and the synchronous belt clamp 430 in sequence. The operation of the synchronous belt pulley group 410 is smooth and quiet, making the telescopic process of the compact telescopic belt conveyor more stable. When the first photoelectric detection group 441 detects the synchronous belt clamp 430, the power assembly 420 stops moving and the telescopic frame 120 reaches the retracted position. At this time, the telescopic frame 120 is out of the projection area of ​​the fire rolling shutter door.

[0066] When the fire shutter door falls, it will not collide with the compact telescopic belt conveyor.
