The present invention relates to a welding machine for attaching filter paper and cap of a filter, comprising left and right main transfer means installed to be moved to the left and right on the top surface of a support frame; left and right filter paper fixing bars installed and fixed on the top surface of the left and right main transfer means; left and right fixing plates installed and fixed on the top surface of the left and right main transfer means; left and right cap holders installed on the fixing plates, respectively, facing each other to be moved to the right and left as well as the left and right main transfer means; left and right heating devices installed on the top surface of the left and right main transfer means, respectively, to be moved in the front and rear sides of the support frame between the left and right filter paper fixing bars and left and right cap holders. The welding machine is comprised to attach a synthetic resin cap on both edges of the filter paper of the filter. The welding machine comprises: mounting grooves formed in the left and right cap holders, respectively; upper and lower cutting grooves penetrating in the upper and lower sides of the mounting grooves; upper and lower cramping cylinders installed on the top and bottom ends of the left and right cap holders to move the piston road toward the upper and lower cutting grooves; a synthetic resin cap installed and inserted in the mounting groove by sliding along the upper and lower cutting grooves while being fixed and attached on the front end of the piston road in each upper and lower cramping cylinder; upper and lower cramping members holding and releasing the upper and lower parts of the synthetic cap. |
