Embodiment 1

[0032] see image 3 with Figure 4 The schematic diagram of the structure of a shielding machine-type foot-operated double-station high-frequency machine is shown. The high-frequency machine is a high-frequency plastic welding machine. Its working principle is to use the oscillator 2 to generate a high-frequency electric field. The high-frequency electric field is applied to the working capacitor, and under the action of the high-frequency electric field, the polar molecules of the melt glue on the workbench 5 move rapidly to generate heat, and achieve the purpose of hot melting under the action of pressure.

[0033] The device for reducing high-frequency radiation of the foot-operated double-station high-frequency machine placed on the ground 14 includes a power supply 1 , an oscillator 2 , a tuning device and a workbench 5 .

[0034] Power supply 1, used to provide working current;

[0035] Oscillator 2, connected to power supply 1, is used to convert the working current i...

Embodiment 2

[0052] The first shield 6 arranged around the tuning capacitor 3 and the second shield 13 arranged around the working capacitor are single-layer shields or multi-layer shields. Both the first shielding case 6 and the second shielding case 13 in this embodiment are single-layer.

Embodiment 3

[0054] In this embodiment, the opposite workstations can be improved to a single-sided double-station structure, so that one person can operate two workbenches 5 at the same time.

Abstract

The invention discloses a method and device for reducing high-frequency radiation for a foot-operated high-frequency machine. The method comprises the steps: firstly enabling a tuning capacitor to bedisposed above an oscillator, enabling the oscillator to be close to a lower electrode of a working capacitor to the maximum extent, and reducing the grounding impedance of the lower electrode of theworking capacitor; keeping the electric connection relation among the tuning capacitor, the oscillator, an upper electrode of the working capacitor and the lower electrode of the working capacitor unchanged; and arranging a shielding cover around the tuning capacitor. The device comprises a power supply, the oscillator, a tuning device and the working capacitor. The high-frequency radiation can begreatly reduced, and the boundary dimension of the high-frequency machine can be greatly reduced.

Description

technical field [0001] The invention relates to the field of high-frequency machines, in particular to a method and device for reducing high-frequency radiation used in foot-operated high-frequency machines. Background technique [0002] Electromagnetic radiation of high-frequency machines is a worldwide problem. For decades, scientific and technological personnel, governments and international organizations have been working hard to explore effective ways to prevent radiation. In the paper "Research on the Effectiveness of Shielding to Reduce Operators' Exposure to High-frequency Radiation of Dielectric Heaters" published in 1992, a variety of shielding scheme designs were proposed to evaluate the shielding effect. "Safety Regulations for High-Frequency Dielectric Heaters" has been repeatedly quoted, and in the name of the "International Labor Office", manufacturers in various countries are required to adopt it, but so far no company has succeeded. [0003] Some people set...
