Abstract
The utility model discloses a plastic extruder. The plastic extruder comprises a feeding device, a cylinder and a direct-current motor, wherein the feeding device comprises a feeding hole, a discharge hole, a drive device, a screw rod and a heater; the drive device is connected with the screw rod; the heater is installed at position of the discharge hole; the cylinder is provided with a hole matched with the discharge hole; a screw is arranged in the cylinder; a heating device is installed between the screw and the inner wall of the cylinder; and a temperature control device is installed on the heating device. The plastic extruder has the beneficial effects that (1) a stepping motor in the feeding device installed on the cylinder drives the screw to rotate, plastics enter the feeding device to be crushed by mixing, and then the heater is installed at the discharge hole, thus the plastics are softened before entering the cylinder; (2) the heating device is installed on the inner wall of the cylinder, thus forming double heating, so that the plastics are further softened and wear is reduced when the screw carries out crushing, thus prolonging the service life of the screw; and (3) the plastic extruder has a simple structure and is convenient to install.
Description
Technical field
The utility model relates to a kind of plastic extruder.
Background technology
In the extruder former, plastic extruder is referred to as main frame usually, and the follow-up equipment plastic extruder supporting with it then is subsidiary engine.Plastic extruder derives twin-screw, multiscrew by original single screw rod through 100 years of development, even does not have different types of machines such as screw rod.Plastic extruder can mate with various plastic shaping subsidiary engines such as tubing, film, handful material, flat filament, strap and crowded nets, forms various plastic extruding forming production lines, produces various plastic products.Therefore no matter the plastic extruder forming machine now or in the future, all is one of the machine of being used widely in the plastic processing industry, but how in machine barrel or outside to adorn heater be the key that people more and more pay attention to, more and more stricter to the requirement of shaped article, and.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of simple in structure, easy for installation and plastic extruder with dual-heated.
The utility model is achieved through the following technical solutions:
A kind of plastic extruder, comprise drawing-in device, machine barrel and dc motor, described drawing-in device is made up of charging aperture, discharging opening, drive unit, screw rod and heater, described drive unit links to each other with screw rod, described heater is installed in the discharging opening place, and described machine barrel is provided with the hole that cooperates with discharging opening, is provided with screw rod in the described machine barrel, between the inwall of described screw rod and machine barrel heater is installed, on the described heater attemperating unit is installed.
As optimized technical scheme, described heater comprises conduction oil and resistance wire, and described resistance wire links to each other with attemperating unit, and attemperating unit is connected with power supply.
As optimized technical scheme, drive unit is stepping motor.
The beneficial effects of the utility model are: 1, the drawing-in device by installing on the machine barrel, stepping motor in the described drawing-in device drives the screw rod rotation, plastics enter drawing-in device and blend, and at discharging opening heater have been installed again, thereby plastics have been softening after entering in the machine barrel; 2, at machine tube inner wall heater is installed, form dual-heated, thereby plastics is more softening, reduce wear when screw rod blends, increase screw rod service life; 3, simple in structure, easy for installation.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following specific embodiment and accompanying drawing.
Fig. 1 is the structural representation of a kind of plastic extruder of the present utility model.
The specific embodiment
A kind of plastic extruder as shown in Figure 1, comprise drawing-in device 1, machine barrel 2 and dc motor 3, it is characterized in that: described drawing-in device is made up of charging aperture 4, discharging opening (not shown), drive unit 5, screw rod 6 and heater 7, described drive unit 5 links to each other with screw rod 6, described heater 7 is installed in the discharging opening place, described machine barrel 2 is provided with the hole (not shown) that cooperates with discharging opening, be provided with screw rod 8 in the described machine barrel 2, between the inwall of described screw rod 8 and machine barrel 2 heater is installed, attemperating unit 9 is installed on the described heater.
Wherein, described heater comprises conduction oil 10 and resistance wire 11, and described resistance wire 11 links to each other with attemperating unit 9, and attemperating unit 9 is connected with power supply 12.
As optimized technical scheme, drive unit 5 is stepping motor.
The beneficial effects of the utility model are: 1, the drawing-in device by installing on the machine barrel, stepping motor in the described drawing-in device drives the screw rod rotation, plastics enter drawing-in device and blend, and at discharging opening heater have been installed again, thereby plastics have been softening after entering in the machine barrel; 2, at machine tube inner wall heater is installed, form dual-heated, thereby plastics is more softening, reduce wear when screw rod blends, increase screw rod service life; 3, simple in structure, easy for installation.
The above only is the specific embodiment of the present utility model, but protection domain of the present utility model is not limited thereto, and any variation or replacement of expecting without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
