Problems solved by technology
During use, the frictional resistance of the guide post as a transmission part is relatively large, and the deformation during movement is relatively large. When the deformation reaches a certain level, the movement resistance of the cutter will be greatly increased, making it difficult to move the cutter. Even stuck, resulting in a shorter service life of transmission components

The invention discloses a cold cutter which can greatly reduce the frictional resistance of the transmission component and hereby can reduce the deformation of the transmission component in the moving process. The cold cutter comprises a frame, a traction plate, a front rest and a rear rest. The traction plate is connected with both the front rest and the rear rest through a connection plate; an air cylinder is arranged between the rear rest and the traction plate; the frame is provided with a mounting base; the mounting base is provided with a gear transmission box; the gear transmission box is internally provided with transmission gears; the inner side of the rear rest and the inner side of the traction plate, which are opposite to each, are respectively provided with parallel racks; the racks are movably arranged in the gear transmission box in a penetrating way and are meshed with the transmission gears; the frame is in the shape of a rectangle, and the left side and the right side of the frame are provided with a pair of parallel guide rails; two ends of the front rest, two ends of the rear rest and two ends of the traction plate are both provided with sliding blocks which match with the guide rails; and rolling balls are arranged between the sliding blocks and the guide rails. The cold cutter is mainly used for the automatic bottle blowing and molding machine.
Description
technical field [0001] The invention relates to a cold cutter device for cutting parisons on an automatic blow molding machine. Background technique [0002] On the automatic blow molding machine, a cold cutter device for cutting off the parison is usually installed. The cylinder between the frame and the traction plate, the cutters are respectively installed on the front and rear tool holders, the frame is provided with a mounting seat, the mounting seat is provided with a gear transmission box, and a transmission gear is arranged in the gear transmission box, and the rear The tool rest and the traction plate are respectively provided with mutually parallel tooth racks on the opposite inner sides, and the tooth racks are movably arranged in the gear transmission box and mesh with the transmission gears respectively. This cold cutting knife device uses the guide post as a guide and support, and under the action of the cylinder, the front and rear knife rests are moved relat...
