Problems solved by technology
[0002] Most of the tensioning mechanisms used on existing equipment are screw tensioning mechanisms. This kind of mechanism can only be adjusted when the equipment is stopped, that is, when the chain is not moving. Realize constant tension in chain operation
[0003] There is also a tensioning mechanism that provides a tensioning effect during the operation of the chain, that is, the cylinder tensioning mechanism, but due to the compressibility of the gas, the chain tension changes greatly and frequently It is easy to cause running jitter when running, and cannot provide a good tensioning effect

Embodiment Construction
[0015] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.
[0016] see Figure 1 to Figure 2 As shown, the above-mentioned chain tensioning mechanism is arranged on the frame 1, and is used to tighten the chain in the chain transmission mechanism. The chain transmission mechanism includes a ring-shaped chain, and at least two rotating The sprocket on the inner side of the chain is used for tensioning the chain. The chain tensioning mechanism includes a guide rail 3 arranged on the frame, a slider 4 arranged on the guide rail 3 that can slide along the length extension direction of the guide rail 3, wherein One sprocket is the first sprocket 2, and the first sprocket 2 can rotate around its own axis and is arranged on the slider 4. The chain tensioning mechanism also includes driving the slider 4 to slide on the guide rail 3 to make the second A sprocket 2 is close to the telescopic cylinder 5 of the c...

The invention discloses a chain tensioning mechanism. The chain tensioning mechanism is arranged on a rack and used for tensioning a chain in a chain transmission mechanism. The chain transmission mechanism comprises the chain and chain wheels. The chain tensioning mechanism comprises guide rails arranged on the rack and a sliding block capable of sliding in the length extension direction of the guide rails and arranged on the guide rails. One chain wheel is a first chain wheel, and the first chain wheel is arranged on the sliding block by rotating around the axial line of the first chain wheel. The chain tensioning mechanism further comprises a telescopic cylinder for driving the sliding block to slide on the guide rails to make the first chain wheel be close to the chain, the telescopic cylinder is arranged on the rack and comprises a cylinder body and an extension end, and the extension end is fixedly connected with the sliding block. The tensioning mechanism is arranged on the chain, the hydraulic cylinder drives the chain wheels to be close to the chain, the chain can be kept tensioned in real time in the operating process, the tensioning tension of the chain can be kept uniform, power of hydraulic oil in the oil cylinder is provided by compressed air of a factory, and therefore the production cost of the factory is reduced.
Description
technical field [0001] The invention relates to a chain tensioning mechanism. Background technique [0002] Most of the tensioning mechanisms used on existing equipment are screw tensioning mechanisms, which can only be adjusted when the equipment is shut down, that is, when the chain does not move, and cannot achieve constant tension in the chain operation. [0003] There is also a tensioning mechanism that provides a tensioning effect during chain operation, that is, a cylinder tensioning mechanism. However, due to the compressibility of the gas, it is easy to cause running vibration when the chain tension changes frequently and frequently, and cannot provide a good tensioning effect. Contents of the invention [0004] The object of the present invention is to provide a tensioning mechanism that can also provide a tensioning effect during the operation of the chain and can maintain a uniform tensioning force of the chain. [0005] In order to achieve the above object, t...
