The invention particularly relates to a mechanical limiting mechanism and method for increasing the movement stroke, and the mechanical limiting mechanism and method are wide in application range. Anarc-faced bumping block and a movement bumping block move under driving of a movement component, blocking bumping blocks are all in a descending state originally, and the arc-faced bumping block is firstly in contact with a slide rod of a first fixed bumping block component, so that the blocking bumping block of the first fixed bumping block component rises up; then, the arc-faced bumping block isin contact with a slide rod of a second fixed bumping block component, and the blocking bumping block of the second fixed bumping block component rises up; the movement bumping block and the blockingbumping block of the second fixed bumping block component are limited, the movement component retreats from a limiting area after conducting reverse movement to make contact with the slide rods of the two fixed bumping block components, so that the two blocking bumping blocks restore to be in the descending state, and limiting is achieved by limiting the movement of the movement component throughascending and descending of the blocking bumping blocks; and the movement range of the movement component can be intervened mutually without being influenced, and the application range is wide.

The invention provides a noodle cooking device. The noodle cooking device comprises a noodle basket, a cooling water pool, a hot water pool, a conveying assembly and a power mechanism, wherein the conveying assembly is connected with the noodle basket and can drive the noodle basket to move between the cooling water pool and the hot water pool; the power mechanism is in driving connection with theconveying assembly, and the noodle basket is located in the hot water pool when noodles are cooked; when noodles are treated with cooling water, the noodle basket moves to the cooling water pool fromthe hot water pool under driving of the conveying assembly; when noodles needs to be heated again, the noodle basket moves to the hot water pool from the cooling water pool, and circulation is carried out through the mode till noodle cooking is completed. By means of the noodle cooking device, the problem that a noodle cooking device in the prior art is inconveniently used is solved.
