Abstract
The utility model discloses a kind of machine barrel of plastic extruder, comprise main barrel and slave cylinder, the outer surface of main barrel and slave cylinder is enclosed with heating tape, and the outer surface of heating tape is coated with asbestos gauge; Heating tape comprises two-layer retainer plate, and the inside of two retainer plates is filled with Electromagnetic Heating sheet; The closeness of main barrel heating tape is greater than the closeness of the heating tape of slave cylinder; Electromagnetic Heating sheet is connected with magnetic coupling, and magnetic coupling is connected with temperature controller.The machine barrel that the utility model provides has good heating effect.
Description
Technical field
The utility model relates to the parts of plastic extruder, is specifically related to a kind of machine barrel of plastic extruder.
Background technology
In plastic extruding forming equipment, plastic extruder is referred to as main frame usually, and the follow-up equipment plastic extruding forming machine supporting with it is then called subsidiary engine.Plastic extruder generally comprises screw rod, machine barrel.Hopper and transmission device, screw rod is arranged on machine barrel inside.Because material needs heating in machine barrel inside, existing mode of heating has electrical heating and oil heating, and namely at the outer surface sandwich establishment of machine barrel, this mode not only increases the operating cost of machine barrel, and the efficiency of heating surface is lower.
In order to solve above-mentioned deficiency of the prior art, the utility model proposes a kind of new solution.
Utility model content
The purpose of this utility model is to provide a kind of machine barrel of plastic extruder.
For reaching above-mentioned purpose, the technical scheme that the utility model adopts is: the machine barrel providing a kind of plastic extruder, comprise the main barrel and slave cylinder that use Flange joint, the outer surface of main barrel and slave cylinder is enclosed with heating tape, the two ends of heating tape are respectively equipped with clamping screw and locking screw holes, and the outer surface of heating tape is coated with asbestos gauge;
Heating tape comprises two-layer retainer plate, and the inside of two retainer plates is filled with Electromagnetic Heating sheet; The outer surface of main barrel and slave cylinder is provided with bolt, and heating tape is fixed on main barrel and slave tube outer surface by bolt and nut cooperation; The closeness of main barrel heating tape is greater than the closeness of the heating tape of slave cylinder; Electromagnetic Heating sheet is connected with magnetic coupling, and magnetic coupling is connected with temperature controller.
Preferably, the length of main barrel is identical with slave cylinder, main barrel is provided with four groups of heating tapes, slave cylinder is provided with three groups of heating tapes.
In sum, the utility model has the following advantages:
The utility model by machine barrel include main barrel and slave cylinder, both are convenient to installing/dismounting by Flange joint, according to actual conditions choice for use main barrel and slave cylinder, can reduce the difficulty of processing and manufacturing simultaneously;
Secondly, the utility model arranges heating tape at the outer surface of machine barrel, and makes the heating tape density of main barrel be greater than the heating tape density of slave cylinder, ensure the temperature of main barrel inside, the Electromagnetic Heating mode simultaneously adopted, has and is easy to control, the advantage that the efficiency of heating surface is high.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
As shown in Figure 1, the utility model provides a kind of machine barrel of plastic extruder, comprise the main barrel 1 and slave cylinder 2 that use flange 3 to connect, the outer surface of main barrel 1 and slave cylinder 2 is enclosed with heating tape 4, the two ends of heating tape 4 are respectively equipped with clamping screw 7 and locking screw holes, when heating tape 4 is after stack shell, use clamping screw 7, locking screw holes and nut to coordinate and heating tape 4 is fixed.The outer surface of heating tape 4 is coated with asbestos gauge, can reduce heat loss, can also prevent electricity from revealing simultaneously.
The inside that heating tape 4 comprises two-layer retainer plate 5, two retainer plate 5 is filled with Electromagnetic Heating sheet 6.The outer surface of main barrel 1 and slave cylinder 2 is provided with bolt 8, and heating tape 4 is fixed on main barrel 1 and slave cylinder 2 outer surface by bolt 8 and nut cooperation.The closeness of main barrel 1 heating tape 4 is greater than the closeness of the heating tape 4 of slave cylinder 2, i.e. the heating tape 4 that the main barrel 1 of equal length is installed is more.Electromagnetic Heating sheet 6 is connected with magnetic coupling, and magnetic coupling is connected with temperature controller.
Although describe in detail detailed description of the invention of the present utility model by reference to the accompanying drawings, should not be construed as the restriction of the protection domain to this patent.In the scope described by claims, the various amendment that those skilled in the art can make without creative work and distortion still belong to the protection domain of this patent.
