Abstract
The invention discloses a heating and cooling system for an extruder. The heating and cooling system comprises a heating device and a cooling device. The heating device comprises a plurality of cast aluminum heaters arranged in a drum of the extruder and first temperature sensors arranged in the cast aluminum heaters; the cooling device comprises a blower communicated with the cast aluminum heaters via ventilation ducts, air quantity sensors arranged in the ventilation ducts and a second temperature sensor arranged in the drum of the extruder; and the first temperature sensors, the air quantity sensors and the second temperature sensor are all connected with a controller. The heating and cooling system is simple in structure and enables temperature control in the drum of the extruder to be more visual; moreover, even one cast aluminum heater is damaged, the temperature in the drum of the extruder can be allowed to accord with production needs by increasing the powers of the rest cast aluminum heaters; the working states of the blower is allowed not to be limited to stopping or operation; the power of the blower is dynamically adjusted; and thus, temperature control is more precise and production efficiency is guaranteed.
Description
Technical field
The invention belongs to the control technical field of extruder, be specifically related to a kind of heating and cooling system for extruder.
Background technology
Extruder can be divided into extrusion and discontinuous extrusion continuously by type of action.Plastic extruder is also the one of plastics machinery.Head, according to the angle of Head material flow path direction and pitch line, is divided into oblique head (angle 120 °) and right-angle handpiece by extruding machine.The shell of head is to be fixed by bolts on fuselage, and the mould in head has core rod to sit, and is fixed on head inlet wire port with nut, and equipped with core rod before core rod seat, the center of core rod and core rod seat is porose, is used for passing through heart yearn.
Extruder of the prior art arranges multiple cast aluminum heaters in machine barrel and is heated, cool down often through arranging aerator, it is ensured that temperature is in claimed range, but mostly adopts aerator to stop or operating, the control model that both is single, it is impossible to guarantee the accurate of temperature.
Extruder of the prior art arranges multiple cast aluminum heaters in machine barrel and is heated, and often through arranging fixing power, cast aluminum heaters is operated, if a cast aluminum heaters breaks down, it is impossible to guarantee that the temperature in machine barrel meets production needs.
Summary of the invention
For solving the technical problem of existing existence, the embodiment of the present invention provides a kind of heating and cooling system for extruder.
For reaching above-mentioned purpose, the technical scheme of the embodiment of the present invention is achieved in that
The embodiment of the present invention provides a kind of heating and cooling system for extruder, it is characterized in that, this system includes heater and chiller, described heater includes several cast aluminum heaters being arranged in machine barrel, and it is arranged on the first temperature sensor in cast aluminum heaters, described chiller includes the aerator connected by ventilation duct with cast aluminum heaters, it is arranged on the air flow sensor in ventilation duct, and it is arranged on the second temperature sensor in machine barrel, described first temperature sensor, air flow sensor, second temperature sensor is all connected with controller.
In such scheme, this device also includes voltage alarm unit, and described voltage alarm unit is connected with controller.Compared with prior art, beneficial effects of the present invention:
Present configuration is simple; temperature in machine barrel is made to control more directly perceived; even and if a cast aluminum heaters damage; can guarantee that in machine barrel, temperature meets production needs by the power of other cast aluminum heaters of raising; the duty making aerator is not limited only to stop or running; dynamically adjust the power of aerator so that temperature controls more accurate, it is ensured that production efficiency.
Accompanying drawing explanation
Fig. 1 is the connection diagram of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
The embodiment of the present invention provides a kind of heating and cooling system for extruder, as shown in Figure 1, this system includes heater and chiller, described heater includes several cast aluminum heaters being arranged in machine barrel, and it is arranged on the first temperature sensor 1 in cast aluminum heaters, described chiller includes the aerator connected by ventilation duct with cast aluminum heaters, it is arranged on the air flow sensor 2 in ventilation duct, and it is arranged on the second temperature sensor 3 in machine barrel, described first temperature sensor 1, air flow sensor 2, second temperature sensor 3 is all connected with controller 4.
This device also includes voltage alarm unit 5, and described voltage alarm unit 5 is connected with controller 4.
The work process of the present invention: during heating: first multiple cast aluminum heaters are operated according to the power set; described first temperature sensor 1 collecting temperature data are to controller 4; when certain cast aluminum heaters damage cannot normal operation time; the first temperature sensor 1 collecting temperature in this cast aluminum heaters is to controller 4; according to the difference of temperature, described controller 4 determines that this cast aluminum heaters is damaged; described controller 4 improves the power of other cast aluminum heaters, it is ensured that the temperature in machine barrel meets production needs.
When the power adjusting cast aluminum heaters exceedes its rated power, described voltage alarm unit 5 is reported to the police, and the cast aluminum heaters that prompting action personnel damage is more, and the power of other cast aluminum heaters is too high, it is easy to cause production accident.
During cooling: first multiple cast aluminum heaters are operated according to the power set, described second temperature sensor 3 gathers temperature data in machine barrel to controller 4, when in machine barrel, temperature exceedes production requirement, described controller 4 strengthens the power of aerator, fast cooling, when in machine barrel, but temperature meets production requirement is about to exceed, described controller 4 keeps the power of aerator, when in machine barrel, temperature meets production requirement but is proximate to lower limit, described controller 4 reduces the power of aerator.
Being sent to controller 4 when air flow sensor 2 detects the air quantity of air outlet, described controller 4 is determined when the air quantity of aerator exists large change, it is determined that this aerator damages, and operation suspension improves the power of other aerators.
