Description

Technical Field

[0001] This utility model relates to a liftable chain conveyor, belonging to the technical field of chain conveyors. Background Technology

[0002] Chain conveyors are conveyors that use chains for traction and load-bearing, or use slats, metal mesh belts, and rollers mounted on the chains to carry materials. They can be classified into chain type, chain plate type, chain mesh type, and slat type, and are often combined with other conveyors and lifting devices to form production lines with various functions.

[0003] Chinese Patent (Publication No.: CN 208560722 U) discloses a chain conveyor, including a support frame and a belt. Support legs are fixedly connected to both sides of the bottom of the support frame. Bearings are fixedly connected to the front and rear ends of both sides of the inner cavity of the support frame. Two sets of bearings are respectively fixedly connected to a first drive shaft and a second drive shaft. Gears are fixedly connected to the front and rear ends of the first and second drive shafts. A conveyor chain meshes between the two gears. A conveyor belt is fixedly connected between the two sets of conveyor chains. A driven pulley is fixedly connected to the front end of the first drive shaft. This invention, through the coordinated use of the support frame, belt, support legs, bearings, first drive shaft, second drive shaft, gears, conveyor chain, conveyor belt, driven pulley, driving pulley, and servo motor, can support the conveyor belt, preventing the conveyor chain from sagging or jamming, thus better ensuring the stability of the device and guaranteeing its smooth and normal operation.

[0004] The aforementioned patents optimize the chain and improve the overall stability of the device. However, in actual use, the lack of a mechanism to lift the conveyor results in poor material loading and unloading flexibility, limited adaptability to various scenarios, and the need for additional transition devices to complete material connection. Excessive height differences also increase manual handling costs.

[0005] Therefore, a lifting chain conveyor is proposed. Utility Model Content

A bidirectional threaded rod 206 is fixedly connected to the output end of the servo motor 205. Threaded sleeves 207 are threadedly connected to both the left and right sides of the outer surface of the bidirectional threaded rod 206.

Fixed blocks 209 are movably connected to the top of the swing rods 208 through rotating shafts, and the fixed blocks 209 are fixedly connected to the bottom of the chain conveyor assembly 100.

[0029] By setting up the lifting mechanism 200, the conveying height of the chain conveyor body 101 can be flexibly adjusted, which can quickly adapt to production equipment, workstations or material containers of different heights without the need for additional transfer devices, reducing equipment investment and space occupation, and improving the flexibility of the production process.

[0030] Example 2

[0031] like Figure 1-4 As shown, in one embodiment, a groove 210 is provided on the top of the base plate 203, a slider 211 is fixedly connected to the bottom of the threaded sleeve 207, and the slider 211 is slidably connected to the inner side of the groove 210. The bottom of each limiting rod 202 is fixedly connected to a movable wheel 212, and the movable wheel 212 is a universal wheel. The bottom of the inner cavity of the limiting rod 202 is fixedly connected to a pressure spring 213, and the top of the pressure spring 213 is fixedly connected to the bottom of the lifting leg 201.
