Abstract
The utility model relates to a plastic extruder which comprises a feed bin, a feeding hole, a screw, a machine barrel, a thermocouple, a programmable controller, a cooling water control valve, a motor, a cooling water pipe and a heating fin, wherein the heating fin and the motor form a heater for the feeding hole; the cooling water control valve and the cooling water pipe form a cooler for the feeding hole; and a preset temperature and a temperature detected by the thermocouple are compared through the programmable controller, so as to control the heater and the cooler for the feeding hole and guarantee the stability of the temperature of the feeding hole. The static differential of temperature is small, so as to effectively guarantee the product quality of subsequent production, at the same time, energy sources are saved, and the work efficiency of the extruder is improved.
Description
Technical field
The utility model belongs to mechanical manufacturing field, relates to a kind of plastic extruder.
Background technology
Plastic extruder is a plastic shaping processed and applied equipment the most widely, and its main feature is: device structure is simple, extrusion is continuous, production efficiency is high, product category is many, simple to operate, and product quality guarantees easily.In process of production, the control of extruder temperature is a most key factor, and temperature not only has the most directly influence to the quality of product, and all influential to the durability of processing stability, equipment etc.Wherein the control of the design of spout and temperature has very big relation with extruder productive rate and energy efficiency, and all materials through extruder all must pass through spout earlier, and the spout temperature is too high, causes the raw material vitreous clinker easily; The spout temperature is low excessively, then can too much consume total driving energy consumption, reduces production efficiency of products.At present, the control of the temperature of extruder spout mainly is through cold valves, will cause temperature control accurate inadequately like this, and in addition, the temperature of cooling water and flow rate usually change along with the temperature of inside plants and even outside.
The utility model content
The purpose of the utility model is to solve the accurate inadequately problem of extruder spout temperature control, provides a kind of spout to have the extruder of temperature control equipment.
For realizing above-mentioned purpose; The technical scheme that the utility model is taked is: a kind of plastic extruder; Comprise: feed bin, spout, screw rod, machine barrel, electroheat pair, Programmable Logic Controller, cooling water control valve, motor, cooling water pipe and heating plate, form the heater of spout by heating plate and motor; The cooling device of forming spout by cooling water control valve, cooling water pipe; Said heater and cooling device detect the discharging opening temperature through electroheat pair and are transferred to Programmable Logic Controller, through comparing with the spout preset temperature, control the open and close of heater and cooling device by Programmable Logic Controller.
Preferably, said cooling water pipe is wound in around the spout according to the even annular of length of spout;
Preferably, said heating plate be installed on spout place cooling water pipe around the gap in.
The utility model compares preset temperature and thermocouple detected temperatures through programmable logic controller (PLC); Heater and cooling device to spout are controlled; Guaranteed the stability of spout temperature, the temperature static difference is little, has effectively ensured the product quality of subsequent production; Save the energy simultaneously, and improved the operating efficiency of extruder.
Description of drawings
Fig. 1 is a kind of structural representation of plastic extruder.
Among the figure:
1 feed bin; 2 spouts;
3 machine barrels; 4 screw rods;
5 electroheat pairs; 6 Programmable Logic Controllers;
7 cooling water control valves; 8 motors;
9 cooling water pipes; 10 heating plates.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further to describe.
Embodiment
As shown in Figure 1, a kind of plastic extruder for the utility model provides comprises: feed bin 1, spout 2; Machine barrel 3, screw rod 4, electroheat pair 5; Programmable Logic Controller 6, cooling water control valve 7, motor 8; Cooling water pipe 9, heating plate 10, the wherein heater of heating plate 10 and motor 8 composition spouts 2; Cooling water control valve 7 and cooling water pipe 9 are formed the cooling device of spouts 2, and cooling water pipe 9 is wound in according to the even annular of length of spout 2 around the spout 2, heating plate 10 be installed on spout go out cooling water pipe 9 around the gap in.
In extruding production process; Detect discharging opening 2 temperature through electroheat pair 5; Be transferred to Programmable Logic Controller 6, Programmable Logic Controller 6 compares through electroheat pair detected temperatures and preset temperature, the open and close of control heater and cooling device; The temperature of spout 2 is higher than preset temperature, opens cooling water control valve 7; The temperature of spout 2 is lower than preset temperature, opens motor 8, and heating plate 10 heats.
