Glue) uniform feeding, sheet extruding and molding, cooling, cut, finally obtain qualified film.
Since temperature is lower in rigid work for extruder, after a period of operation, the temperature of extruder can become again
Height, the quality and efficiency that this too low or excessively high temperature can all work to extruder impact.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of cold feed extruders that temperature accurately controls.
The technical solution adopted by the present invention to solve the technical problems is: cold feed extruder, including machine body base, described
Extrusion device is provided in machine body base, the extrusion device includes machine barrel, is provided with screw rod in the machine barrel, further includes driving
Motor, the driving motor are connect by shaft coupling and speed reducer with screw rod, and spout is additionally provided on the machine barrel, described to feed
It is provided with forced-feeding device at material mouth, further includes for controlling machine barrel, the temperature control equipment of screw rod and drawing-in device temperature.
Further, the inside screw, which is provided with water, cools and heats channel, the water cools and heats tunnel ends
Portion is connect by rotary joint with temperature control equipment.
Further, the machine barrel is that spiral is jacket structured, the jacket structured internal layer of the spiral and temperature control are filled
Set circulation connection.
Further, the screw slenderness ratio is 12:1.
Further, the nut stem material is surface carburization hardening, plating hard chrome processing 38CrMoAlA.
The beneficial effects of the present invention are: the extruder of the application can control the temperature of machine barrel, screw rod and drawing-in device
Within 38 degrees Celsius, guarantee the quality of extruded product, while this structure can guarantee continuous extrusion work, and screw rod is due to using
38CrMoAlA, therefore there is highly corrosion resistant, to extend the service life of this equipment.
Detailed description of the invention
Fig. 1 is cold feed extruder schematic diagram.
In the figure, it is marked as machine body base 1, machine barrel 2, screw rod 3, driving motor 4, shaft coupling 5, speed reducer 6, forced feed dress
Set 7, temperature control equipment 8.
Specific embodiment
The present invention is further described with reference to the accompanying drawings and detailed description.
Cold feed extruder as shown in Figure 1, including machine body base 1 are provided with extrusion device in the machine body base 1,
The extrusion device includes machine barrel 2, is provided with screw rod 3 in the machine barrel 2, further includes driving motor 4, and the driving motor 4 is logical
It crosses shaft coupling 5 and speed reducer 6 is connect with screw rod 3, spout is additionally provided on the machine barrel 2, be provided at the spout strong
Drawing-in device 7 processed further includes for controlling machine barrel 2, the temperature control equipment 8 of screw rod 3 and drawing-in device temperature, above-mentioned feeding dress
It sets including feeding pedestal, on feeding pedestal, feeding gate is provided on feeding pedestal, bushing is provided in feeding pedestal, it is above-mentioned to feed
Material pedestal designs for jacket type, and above-mentioned temperature control equipment 8 is connect with the interlayer closed loop of feeding seat, is arranged inside the screw rod 3
There is water to cool and heat channel, the water cools and heats channel end and connect by rotary joint with temperature control equipment 8, institute
Stating machine barrel 2 is that spiral is jacket structured, and the jacket structured internal layer of the spiral is connected to the circulation of temperature control equipment 8, above-mentioned temperature
Control device 8 is the water circulation thermostat with electric heater, closed loop formula.Including 3 and circulation path, 3 circulations
Access is respectively connected to control machine barrel 2, screw rod 3 and drawing-in device, and heat source is electric heater, and the type of cooling is that water is cooling.Circulation
Temperature sensor is provided in circuit, the temperature sensor uses PT thermocouple.Pass through the recirculated water of detection water pump driving
Temperature is compared with presetting temperature value.Electrical heating elements are inserted in closed loop formula water, this heating element can be easy
Replacement.The heating and cooling of this temperature controller have been all made of PID control system.It is cooling that return water is expelled directly out using solenoid valve,
It is fast with cooling velocity, feature with high accuracy.
In specific works, raw material is entered in machine barrel 2 by forced-feeding device 7, is started motor, is subtracted by speed reducer 6
Speed, speed reducer 6 drive screw rod 3 to rotate, are squeezed out product by the rotation of screw rod 3, simultaneously because temperature control equipment 8 is set
It sets, it is ensured that machine barrel 2, the temperature stability of screw rod 3 and drawing-in device, to improve the property of extruder are controlled when work
Can, and the retarder of the application is Hardened gear face cylinder gear speed reducer.Gear uses high-quality low-carbon alloy steel, grinds through carburizing and quenching
