Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, and in particular to a retractable belt conveyor. Background Technology

[0002] Belt conveyors, also known as rubber belt conveyors, are widely used in various industries such as home appliances, electronics, electrical appliances, machinery, tobacco, injection molding, postal services, printing, and food for the assembly, testing, debugging, packaging, and transportation of goods. Belt conveyors can be used for horizontal or inclined transport, are very convenient to use, and are widely used in various modern industrial enterprises, such as underground mine tunnels, mine surface transportation systems, open-pit mines, and ore processing plants.

[0003] Publication No. (CN221318452U) discloses a mining belt conveyor. During use, a conveyor pump is activated to extract water from inside the housing and deliver it to atomizing nozzles through connecting pipes and a distribution box while the conveyor belt is transporting coal. The water is then evenly sprayed onto the coal on the conveyor belt through multiple atomizing nozzles, making the coal surface moist and reducing dust generation. However, the conveying length of the conveyor belt in the above device cannot be adjusted according to usage requirements, which leads to poor device performance and requires improvement. Utility Model Content

[0007] The transport mechanism includes a fixed box, a movable seat is provided inside the fixed box, a threaded rod is installed on the movable seat, a knob is provided at one end of the threaded rod, a connecting rod is fixed to the right side wall of the movable seat, a movable platform is fixed to the end of the connecting rod away from the movable seat, a fixed plate is installed above the fixed box, a first conveyor roller is provided on the fixed plate, a motor is connected to the first conveyor roller, a movable plate is installed above the movable platform, a second conveyor roller is provided on the movable plate, a conveyor belt is provided on the second conveyor roller, and a tensioning component is provided on the fixed box;

[0008] The limiting mechanism includes a positioning column installed on the first conveying roller and the second conveying roller. A limiting plate is fixed to one end of the positioning column, and a fixing bolt is passed through the limiting plate.

[0009] Preferably, the tensioning assembly includes a fixing block installed on the front and rear surfaces of the fixing box, an electric push rod installed on the upper surface of the fixing block, a lifting plate fixed to the telescopic end of the electric push rod, an mounting plate fixed to the lifting plate, and a tensioning roller provided on the mounting plate.

[0010] Preferably, the threaded rod is rotatably connected to the fixed box, and the movable seat is slidably connected to the fixed box.

[0011] Preferably, the connecting rod is slidably connected to the fixed box.

[0012] Preferably, there are two positioning pins on each limiting plate.

[0013] Preferably, the tension roller is rotatably connected to the mounting plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] By setting up a transport mechanism, the conveyor belt length can be adjusted according to the conveying requirements when using the device. The tensioning component is controlled to loosen the conveyor belt. Turning the knob drives the threaded rod to rotate, which in turn moves the movable seat to the right along the fixed box. The movable seat moves the movable table to the right via the connecting rod, and the movable table moves the second conveyor roller to the right via the movable plate. The movement of the second conveyor roller to the right re-tensions the conveyor belt. Once the device is adjusted, it can be put into use. The conveyor belt length can be adjusted according to the usage requirements, thus effectively improving the device's performance.

[0016] The present invention will be further described below with reference to the accompanying drawings. Attached Figure Description
