Multi-station bottle blowing machine without moving mold locking frame

Abstract

The invention provides a multi-station bottle blowing machine without moving a mold locking frame. The multi-station bottle blowing machine comprises an extrusion unit, a cutter unit, at least two blow molding units, and a blank clamping manipulator unit; the extrusion unit is provided with an extrusion mold head and an air blowing pipe and is used for extruding a plastic blank pipe in a hollow state; the cutter unit is used for cutting off the plastic blank pipe; each blow molding unit is provided with a machine frame and a mold locking frame; the mold locking frames are fixed on the machine frames in a static mode; the mold locking frames are provided with molds; the molds are used for conducting blow molding on plastic blank pipes; and the blank clamping manipulator unit is used for performing reciprocating motion between the extrusion unit and each blow molding unit, clamping the plastic blank pipes extruded by the extrusion unit, keeping the plastic blank pipe s to be hollow and bulged, and sequentially placing the plastic blank pipes into the molds of the blow molding units. According to the machine, the manipulator unit is adopted to clamp the plastic blank pipes and send the plastic blank pipes to the molds of the blow molding units, the mold locking frames do not move in the whole process flow, vibration and energy consumption are effectively reduced, the manipulator unit is small in movement inertia, small in required power, and easy to brake, and high-speed and stable movement of the manipulator unit is easily achieved, so that the single-machine yield is improved.

Description

technical field [0001] The invention belongs to the field of rubber and plastic machinery, and in particular relates to a multi-station bottle blowing machine without moving the clamping frame. Background technique [0002] At present, there are two types of multi-station plastic extrusion blow molding machines on the market: 1) the clamping frame translation method, usually only two stations can be used; 2) the clamping frame rotation method, more stations can be done, There are horizontal rotation and vertical rotation structure. But both of these two methods need to move the mold clamping frame. The mold clamping frame is equipped with molds, clamping mechanisms and power devices. It is usually heavy, has a large moment of inertia, and consumes a lot of energy. In addition, in order to pursue output, it requires a higher speed of movement. (For example, the average speed of the translational clamping frame reaches 1 m / s), the driving force required is large, and the brak...

Problems solved by technology

But both of these two methods need to move the mold clamping frame. The mold clamping frame is equipped with molds, clamping mechanisms and power devices. It is usually heavy, has a large moment of inertia, and consumes a lot of energy. In addition, in order to pursue output, it requires a higher speed of movement. (For example, the average speed of the translational clamping frame reaches 1 m / s), the driving force required is large, and the braking force required for braking is also large. Frequent starting and braking not only waste a lot of energy, but also cause large vibration and movement If it is unbalanced, it is difficult to further increase the movement speed, that is, it is difficult to increase the production efficiency
