For example, the fixed-length driver 42 is an air cylinder, but of course, a hydraulic cylinder or an electric push rod is used according to actual needs, but not limited thereto.

The working principle of the automatic fixed-length rib feeding and cutting equipment of the utility model is explained by combining the accompanying drawings: in fig. 1, when the required length of the web segment is the distance between the severing device 20 and the leftmost length-determining device 40, the leftmost length-determining device 40 now projects into the channel 31, and the remaining length-determining devices 40 remain removed from the channel 31; when the rib 200 conveyed by the rib conveying mechanism 10 blocks the length fixing mechanism 40 at the leftmost position for length fixing, the cutting mechanism 20 can cut the rib 200; when a rib segment needs to be cut out again on the rib 200, at this time, the leftmost length-fixing mechanism 40 is moved away from the channel 31 first, the rib 200 is continuously conveyed forwards by the rib conveying mechanism 10, and the rib segment is driven to move forwards together by the forward conveyed rib 200 until the rib segment passes through the leftmost length-fixing mechanism 40; after the rib section is driven by rib 200 and passes through leftmost length fixing mechanism 40, send muscle mechanism 10 to need to make rib 200 transport back, avoid rib 200 to move forward excessively and cause leftmost length fixing mechanism 40 to stop the fixed length to rib 200 again. The remaining length-determining mechanisms 40 are used the same as the leftmost length-determining mechanism 40, and therefore, the detailed description thereof is omitted.

Compared with the prior art, by means of the plurality of length fixing mechanisms 40 which are mutually separated by the preset distance along the conveying direction of the ribs 200 and are respectively arranged corresponding to the long groove bodies 30, each length fixing mechanism 40 can move into or out of the channel 31, each length fixing mechanism 40 stops the ribs 200 conveyed by the rib conveying mechanism 10 from continuously advancing when extending into the channel 31, each length fixing mechanism 40 allows the ribs 200 conveyed by the rib conveying mechanism 10 to continuously advance when moving out of the channel 31, the cutting mechanism 20 cuts rib sections with different lengths into the ribs 200 conveyed by the rib conveying mechanism 10 under the matching of the different length fixing mechanisms 40 extending into the channel 31, and therefore the purposes of saving time and improving working efficiency are achieved, in addition, the length fixing difficulty of the ribs 200 is reduced because the ribs 200 conveyed by the rib conveying mechanism 10 are fixed by the stopping of the length fixing mechanisms 40 instead of controlling the length fixing of the ribs 200 by the rib conveying mechanism 10.

It should be noted that, in order to improve the degree of automation, the tendon feeding and cutting device 100 with automatic length fixing of the present invention may be electrically connected to a controller, which may be a programming controller or a control circuit, or, of course, may be operated by an operator with the tendon feeding and cutting device 100 with automatic length fixing of the present invention.
