Abstract
The utility model discloses a molten plastic pump, which consists of a gear pump 4, an extruder joint 5 and a machine head joint 6. The gear pump 4 is arranged between the extruder joint 5 and the machine head joint 6. A control system automatically adjusts the working parameters of the extrusion shaping system and promotes best cooperation for the system working parameters, so as to stably transport the material to the machine head in certain pressure, flux and temperature, and ultimately form the product with stable size precision and quality.
Description
The utility model relates to a kind of improvement of the pump housing, and specifically a kind of plastic melt pump is applicable to the plastics extrusion equipment.
General plastics extrusion equipment comprises that extruder, head and subsidiary engine constitute at present, and extruder and head directly are connected as a single entity, and when extruded material, pressure oscillation is big, extrusion moulding product dimensional accuracy instability, and waste of material is many, and energy resource consumption is big.
The purpose of this utility model is to provide a kind of plastic melt pump that can stablize mass flow, steady pressure, raising product size precision in the plastic extruding forming production process, reduce material consumption, energy savings.
The utility model is achieved in that this plastic melt pump is by gear pump, the extruder connector, the head connector constitutes, gear pump is located between extruder connector and the head connector, sheathed heater on the clutch disk of extruder connector and gear pump, on the extruder connector, also be provided with pressure sensor tube connector and temperature sensor joint, when using the utility model, extruder is connected on the extruder connector, head is connected on the head connector, and pressure sensor is fixed on the pressure sensor tube connector, temperature sensor is fixed on the temperature sensor joint, temperature sensor and pressure sensor are with operating temperature, pressure parameter is passed to automatic control system, and automatically adjust, make each running parameter reach best fit, thereby the plastifying fusion material that extruder is extruded enters the plastic melt pump, through the impetus of pump, makes material by certain pressure, flow, the stable head that is transported to finally forms dimensional accuracy, stay-in-grade goods.
The utility model has the advantages that: simple in structure, control the degree height automatically, can improve the dimensional accuracy and the product quality of injecting products.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model office cross-sectional schematic.
Fig. 2 is the utility model application controls schematic diagram.
Make the utility model with reference to accompanying drawing 1.This plastic melt pump is made of gear pump 4, extruder connector 5, head connector 6, and gear pump 4 is located between extruder connector 5 and the head connector 6, sheathed heater 3 on the clutch disk of extruder connector 5 and gear pump 4.On extruder connector 5, also be provided with pressure sensor tube connector 1 and temperature sensor joint 2.
Claims (2)
1, a kind of plastic melt pump, constitute by gear pump (4), extruder connector (5), head connector (6), it is characterized in that gear pump (4) is located between extruder connector (5) and the head connector (6), sheathed heater (3) on the clutch disk of extruder connector (5) and gear pump (4).
2, plastic melt pump according to claim 1 is characterized in that also being provided with pressure sensor tube connector (1) and temperature sensor joint (2) on extruder connector (5).
