Double-layer plastic film thermal cutting and bonding knife

Abstract

The invention discloses a double-layer plastic film thermal cutting and bonding knife which comprises a servo roll, a rotary dead knife, a traction iron roll, a traction rubber roll, electric heating rods, a fixed electric heating rod, a blade assembly, and the like. The servo roll is arranged at the front end of the rotary dead knife, the fixed electric heating rod and the blade assembly are arranged above the rotary dead knife, blades are arranged on the fixed electric heating rod and the blade assembly, the electric heating rods are arranged on the fixed electric heating rod and the blade assembly, the traction iron roll is arranged under the rotary dead knife, the traction iron roll and the traction rubber roll are arranged on the two sides of a double-layer film, and a rotary dead knife box is arranged on the rotary dead knife. According to the double-layer plastic film thermal cutting and bonding knife, the electric heating rods and the servo roll are arranged, double-layer plastics are combined through heat, and the integration of cutting and bonding is achieved; sizes of plastic films are different when one machine is used for producing several plastic films at the same time; the problems of low efficiency and high energy consumption in the traditional production process are avoided. The double-layer plastic film thermal cutting and bonding knife is simple in structure and convenient to operate, improves production efficiency, reduces energy consumption, saves energy and reduces cost.

Description
