The purpose is to provide the improvement of a cooling control system of a plastic extruding machine. The cooling control system has the characteristics of exact temperature difference control, stable product quality, simple structure, easy production and low cost. The utility model is characterized in that the cooling control system of a plastic extruding machine comprises screw cylinders and screw cylinder cooling sleeves which are concentrically arranged on the outer circumference surfaces of the screw cylinders, wherein cooling water is arranged in a cooling cavity between the screw cylinder and the screw cylinder; the cooling control system is also provided with a refrigeration control system; in the refrigeration control system, a cooling liquid circulating copper pipes are wound on the outer circumference surfaces of the screw cylinders, and are connected with refrigerating compressors, and temperature measurement feedback thermal resistors are arranged on the screw cylinder cooling sleeves and are connected with a temperature control system of an electric appliance; two sets of cooling liquid circulating copper pipes are wounded on the outer circumference surfaces of the screw cylinders, and are respectively communicated with the refrigerating compressors, and the cooling liquid circulating copper pipes are respectively wounded at the front half part and the back half part of each screw cylinder.
Description
Technical field
The utility model relates to a kind of extrusion screw rod cooling control system of rubber and plastic extruder cooling control system, especially rubber and plastic extruder.
Background technology
The rubber and plastic product needs cold-extruded to go out at the processing extrusion, because can produce friction between the extrusion screw rod 11 of rubber and plastic extruder and the barrel 3, produces heat in the rubber and plastic extruding machine barrel thereby make, so that cause the quality instability of rubber and plastic product.The cooling control system of present rubber and plastic extruder both domestic and external all adopts water-cooled from the beginning principle, promptly cools off the heat that friction produces of controlling of barrel 3 methods between barrel 3 and barrel coolant jacket 9 in order to water.Control method is the displays temperature according to temp controlled meter, controls the flow of water with the openings of sizes of adjusting water inlet control valve 8, and cooling water is discharged from discharge outlet 12.
According to the characteristics of extruding of rubber and plastic product, the difference variation in extrusion in the barrel 3 should be controlled at more among a small circle.But because bigger variation takes place with the difference of climate in the temperature of cooling water, the way that solves has only according to the temperature of water and adjusts the rubber-plastics material Recipe, can only produce reluctantly with such control method, do not guarantee product quality, and cooling water is directly discharging, and water resource waste is very big like this.
Summary of the invention
The purpose of this utility model provides a kind of improvement of rubber and plastic extruder cooling control system, this cooling control system should be able to overcome the deficiency of above-mentioned background technology, has temperature difference precise control, constant product quality, and simple in structure, easy to manufacture, lower-cost characteristics.
The technical scheme that the utility model proposes is: rubber and plastic extruder cooling control system, comprise the barrel coolant jacket that barrel and barrel outer circumference surface are installed with one heart, cooling chamber between barrel and the barrel is built-in with cooling water, and described cooling control system is equipped with refrigeration control system.
In the described refrigeration control system: be wound with the liquid circulation copper pipe on the outer circumference surface of barrel, this liquid circulation copper pipe and refrigeration compressor join, and the thermal resistance of thermometric feedback also is housed on the barrel coolant jacket, and this thermal resistance joins with the electrical equipment temperature control system again.
The liquid circulation copper pipe of coiling on the outer circumference surface of described barrel is divided into two covers, communicates with refrigeration compressor respectively separately, and is wound on the first half of barrel and latter half of respectively.
Because by installing refrigeration control system additional between barrel and the cooling swivel nut layer, cooling water temperature can be controlled between positive and negative 2 degree, the heat that friction produces between screw rod and the barrel is accurately controlled, satisfied the requirement that the rubber-plastics material cold-extruded goes out, and no longer need to consider the variations in temperature problem that the variation owing to climate produces, guaranteed rubber-plastics material Recipe stability, the quality of product is guaranteed.In addition, be conventional refrigeration control system owing to what adopt, thereby structure is also simple, easily manufactured easy, cost is also lower.
Description of drawings
Accompanying drawing is a main TV structure schematic diagram of the present utility model.
The specific embodiment
As shown in the figure, rubber and plastic extruder cooling control system comprises the barrel 3 of screw rod 11 outsides, and the barrel coolant jacket 9 installed of barrel outer circumference surface external concentric, cooling chamber 2 between barrel and the barrel is built-in with cooling water, and described cooling control system is equipped with refrigeration control system.
In the described refrigeration control system: be wound with liquid circulation copper pipe 4 on the outer circumference surface of barrel, this liquid circulation copper pipe and refrigeration compressor 6 join, and make the cooling fluid reciprocation cycle to constitute basic refrigerating circuit.In addition, for reaching the accurate temperature controlling purpose, the thermal resistance 1 of thermometric feedback also is housed on the barrel coolant jacket, this thermal resistance joins with the temperature control system 10 that is installed on the extrusion molding fuselage 7 again, at any time measured temperature data is passed to temperature control system, determine to start or close refrigeration compressor by temperature control system.
For obtaining more effective refrigeration, the liquid circulation copper pipe of coiling on the outer circumference surface of described barrel is divided into two covers, communicate with refrigeration compressor 6 respectively separately, and be wound on the first half of barrel 3 and latter half of respectively, constitute liquid circulation loop separately.
