Abstract

The invention discloses a die cutting device of a plastic bag notching machine. The die cutting device comprises a rack, an air cylinder, guide rods, a cutting board, a stamping knife and a stamping knife equalizing adjusting device, wherein the stamping knife equalizing control device is composed of an adjusting board, a stamping knife seat board, an elastic connecting mechanism and adjusting screws; the elastic connecting mechanism is composed of sliding rods, springs and spring bases, and the elastic connecting mechanism is used for causing the adjusting board and the stamping knife seat board to form an elastic connection; and the four adjusting screws are arranged on the adjusting board, the contact angle of the stamping knife and the cutting board is changed through screwing or unreeling the adjusting screws in one direction, and the die cutting barycenter is adjusted. The die cutting device provided by the invention has the advantages that the structure is simple, stable and reliable, and the adjustment is convenient and rapid.

Description

technical field [0001] The invention relates to a plastic bag processing equipment. Background technique [0002] The portable plastic bags (convenience bags) commonly used in people's daily life are all processed from tubular plastic films. First, the two ends of the plastic film are heated by a bag making machine to form two sealing lines, and then cut into sections. The rectangular plastic film section, the bag making machine produces a certain number of rectangular plastic film sections with both ends sealed, and then automatically stacks them into a stack, and then punches through the punching machine, and cuts one end of the plastic film into a Handle-shaped plastic bags. During the punching process of the punching machine, because the punching knife is in a "W" shape, the force is uneven, and the center of gravity will also change when the model of the plastic bag is changed, requiring frequent adjustments. In addition, the frame of the punching device will be defor...
