Description

Technical Field

[0001] The invention relates to an electric liquid level line material injection device, and relates to the technical field of blow molding machinery. Background Art

[0002] The extruder head of the electric liquid level line is currently a more common liquid level line extrusion mechanical equipment, and the liquid level line extruder head will be installed with a liquid level line shooting device to provide the extruder head with liquid level line material. However, the shooting process stability of the electric liquid level line shooting device currently in use is not high, and the oil cylinder is used as the liquid level line shooting actuator. When the oil cylinder stores material in the liquid level line, the return oil throttling method is used as the storage back pressure. This method can be adopted when the liquid level line output is fixed. When the liquid level line output increases or decreases, the return oil back pressure needs to be adjusted accordingly, and the adjustment process is relatively cumbersome. The liquid level line injection speed is achieved by the throttle valve. The liquid level line is injected at the same time during the main injection. The injection pressure is closely related to the main injection pressure. When the pressure does not match, the appearance of the liquid level line on the injected tube blank is poor and does not meet the production requirements, thus affecting the product quality.

[0018] In this embodiment, the piston drive mechanism includes an electric cylinder 8 and an electric cylinder fixing seat 9. The electric cylinder 8 is fixed on the electric cylinder fixing seat 9. The model of the electric cylinder 8 can be selected according to actual needs, and the model of the electric cylinder 8 commonly used on the market can be selected. The electric cylinder fixing seat 9 is connected to the head of the diversion mechanism 2. In order to further improve the stability of the electric cylinder 8 when it is fixed, a flange 10 is connected to the rear end face of the electric cylinder fixing seat 9. The telescopic movable end 801 of the electric cylinder 8 is connected and fixed to the end of the piston rod 4. In practical applications, a servo electric cylinder controlled by a servo system is preferably used, so that the control is more precise and convenient. The piston is driven by the electric cylinder 8 to move in the diversion mechanism 2 to realize the injection process. The whole process is simple and convenient, with high controllability, high control accuracy, and high reliability.

[0019] In this embodiment, in order to improve the stability of the electric cylinder 8 during operation, a plurality of guide pillars 11 are connected between the electric cylinder fixing seat 9 and the head of the diversion mechanism 2, and the ends of the guide pillars 11 are vertically connected and fixed to the seat plate of the electric cylinder fixing seat 9. Furthermore, in order to prevent the electric cylinder 8 from rotating as a whole, a synchronization plate 12 is provided on the guide pillar 11, and a plurality of guide pillar holes for the guide pillars 11 to pass through are provided on the edge of the plate body of the synchronization plate 12. The telescopic movable end 801 of the electric cylinder 8 is connected and fixed to the middle part of the front side surface of the synchronization plate 12, and the front end part of the piston rod 4 is connected and fixed to the middle part of the rear side surface of the synchronization plate 12.

The electric liquid level line injection device is provided with an electric cylinder 8 and a piston motion assembly matched with the electric cylinder 8, so that the injection speed control is more accurate and reliable, and the operation is convenient and quick, which effectively improves the appearance effect of the product's liquid level line, improves product quality, and is highly practical.
