Problems solved by technology
[0003] The existing tensioning device is not efficient due to its large structural size, heavy weight, and small deformation. Manufacturers are often willing to add tensioning sprockets rather than tensioning devices. This has always been a problem that equipment manufacturers have been troubled by.

The invention discloses a support tensioning device which comprises a chain, and further comprises a tensioning assembly and a supporting assembly, wherein the tensioning assembly is positioned above the chain, is connected with the chain in a meshing manner and is used for adjusting the tensioning degree of the chain to guarantee normal operation of the chain; and the supporting assembly is positioned below the tensioning assembly and is used for supporting the tensioning assembly, controlling the position of the tensioning assembly and limiting the moving direction of the tensioning assembly, to guarantee normal operation of the device. The support tensioning device provided by the invention enables the chain transmission to be kept in a stable state all the time; particularly during the chain transmission of a sludge plate-and-frame filter press, the tightness of the chain can be adjusted in time according to a site working condition, and meanwhile, vibration and wear of the chain are relieved, and the use efficiency of equipment is improved; and furthermore, the tensioning device can realize the use function under a small volume and a light weight as far as possible, to fulfill the aims of simplicity and convenience for mounting and maintenance, easiness in use and operation, high working efficiency and the like.
Description
technical field [0001] The invention relates to a tensioning device for a chain drive. Background technique [0002] At present, chain transmission is widely used as a mature transmission system. Due to its simple principle and convenient installation and maintenance, it has been favored by many equipment manufacturers. At the same time, due to the simple structure of chain transmission, its service life is short and it is easy to wear and tear. Especially on sludge plate and frame filter press equipment. Sludge plate and frame filter press is already a very mature sludge dewatering equipment, which has been developed to the level of automation or semi-automation. Poor meshing and chain vibration caused by excessive tension, and also to increase the wrap angle of the chain and sprocket, a tensioning device needs to be installed. [0003] The existing tensioning device is not efficient due to its large structural size, heavy weight, and small deformation. Manufacturers are ...
