Tension-adjustable net drawing mechanism for netting machine

The utility model belongs to the technical field of netting machines, and particularly relates to a net drawing mechanism with adjustable tension for a netting machine. A thorn shaft assembly is arranged on the netting machine, and the netting drawing mechanism comprises a clutch connected with the thorn shaft assembly and a rubber roller assembly connected with the clutch. The rubber roller assembly comprises a rubber roller shaft and a compression roller, and a rubber roller shaft chain wheel is fixed on the rubber roller shaft; a clutch chain wheel is arranged at the output end of the clutch, and a chain is arranged between the clutch chain wheel and the rubber roller shaft chain wheel. The output speed of the clutch can be adjusted according to the magnitude of voltage, then the rotating speed of the rubber roller shaft is changed, the pulling force of the rubber roller on the PET macromolecule rechecking monofilament hexagonal net is changed, the position of the pressing roller can be elastically changed
