Problems solved by technology

[0002] At present, the heating method used for the screw of the spinning machine is generally a resistance heating ring heating, and the heat is transferred to the screw barrel through contact conduction. This heating method has the following disadvantages: 1. The heat loss is large, and the resistance wire is wound. The inner and outer sides of the heating ring generate heat, and the heat on the inner surface (close to the barrel) is transferred to the barrel, while most of the outer heat is lost to the air, resulting in a waste of electrical energy; 2. The ambient temperature rises, due to the large amount of heat Emission, the temperature of the surrounding environment rises, especially in summer, which has a great impact on the production environment, and the on-site working temperature exceeds 45°C; 3. The service life is short and the amount of maintenance is large. Due to the use of resistance wire for heating, the heating temperature is as high as 300°C , the resistance wire is easy to burn out due to high temperature aging, therefore, the maintenance workload is relatively large, and the maintenance cost is increased

Embodiment 1

[0014] Such as figure 1 , figure 2 As shown, the screw barrel device described in this embodiment mainly includes a screw barrel 1, and outside the screw barrel 1, a material consisting of a high temperature resistant cloth 2-2 and an aluminum silicate insulation cotton 2-1 with a thickness of 15 mm is laid. Insulation layer 2, high temperature resistant cloth 2-2 is evenly wound on the aluminum silicate insulation cotton 2-1 layer by layer, and then an insulation board with a thickness of 1 mm is set on the insulation layer 2 as an insulation device 4 through rivets, and layer by layer on the insulation board The induction coil 5 is wound, and the induction coil 5 is generally composed of a high temperature resistant wire with a high temperature resistance of 500°C. A heat-shrinkable sleeve 10 is sheathed outside the induction coil 5 , both ends of the induction coil 5 are connected to ceramic joints, and the induction coil 5 is electrically connected to the electromagnetic...

Embodiment 2

[0018] Such as figure 1 As shown, the screw barrel heating method of the spinning machine described in this embodiment is suitable for the screw of Φ105 mm and below Φ105 mm, and the 220V, 50 / 60Hz alternating current is connected to the electrical control cabinet 8, and the electrical control cabinet 8 controls The electromagnetic controller 7 converts the alternating current into a direct current, and then converts the direct current into a high-frequency current with a frequency of 20-40KHz. The high-speed changing high-frequency current will generate a high-speed changing alternating magnetic field through the induction coil. When the magnetic field When the magnetic lines of force pass through the screw barrel 1 of magnetically conductive metal material, countless small eddy currents will be generated in the metal, which will make the screw barrel 1 itself heat up rapidly and reach a heating temperature of 280°C ~ 300°C ± 1°C, so that the inside of the screw barrel The mat...

Abstract

The method for heating a screw cylinder of a spinning machine, designed by the invention, specifically comprises that: for the screws equal to [phi]105 millimeters and below [phi]105 millimeters, electromagnetic heating is implemented in each heating region by using 220V power source; three-phase four-wire 380V power source is utilized to power apparatus above [phi]105 millimeters, and 2-4 electromagnetic heating coils are utilized to heat in each hearing region; an electromagnetic controller rectifies alternating current to direct current and converts the direct current into high-frequency current having frequency of 20-40kHz; when magnetic lines of force pass through the screw cylinder of a magnetically conductive metal material, numberless small vortexes are generated in the metal so that material in the screw cylinder reaches ideal heating effect. The screw cylinder device resulted from the invention makes use of electromagnetic induction principle to heat the screw cylinder and is provided with a heat preservation layer, a heat insulation layer and the like outside of the screw cylinder, thus solving the problem that heat is dispersed to air to maximize heat efficiency.
