Multi-station variable-pitch clamp

The utility model discloses a multi-station variable-pitch clamp, and relates to the technical field of food packaging machinery. The clamping device comprises a plurality of clamping assemblies which are arranged in parallel, a variable-pitch adjusting mechanism for driving the clamping assemblies to carry out spacing adjustment, a clamping driving mechanism for driving the clamping assemblies to synchronously carry out clamping actions, and a material pushing mechanism for pushing clamped materials out between first clamping pieces and second clamping pieces of the clamping assemblies. According to the utility model, the distance adjustment among the multiple groups of clamping assemblies is realized through the variable-distance adjusting mechanism, and the clamped materials are pushed out from the clamping assemblies through the material pushing mechanism, so that the clamped materials are prevented from being adhered to the clamping assemblies, the problems in the prior art can be effectively solved, and
