Variable optical liquid crystal welding goggles include a control module (1), an optical trigger module (2), a photosensitive module (3), a manually setting module (4), a regulator module (5) and liquid crystal lenses (6). The manually setting module (4) is used to set related parameters of the variable optical liquid crystal welding goggles. When welding, the optical trigger module (2) receives the optical signal of the welding arc and triggers the control module (1); the photosensitive module (3) is used to capture the information of intensity of welding arc and send it to the control module (1); the control module (1) sends a control signal to the regulator module (5) basing on the information of intensity of welding arc received from the photosensitive module (3) and the parameters set by the manually setting module (4); the regulator module (5) adjusts the rate of light transmission of the liquid crystal lens (6) according to the received control signal. The variable optical liquid crystal welding goggles increase operative flexibility of the welders while protecting eyes of welders.

The invention discloses an efficient and energy-saving shrink machine for heat shrink tubes on an assembly line. The efficient and energy-saving shrink machine comprises a trapezoidal support. Rollers are mounted on the upper side of the trapezoidal support, rotary shafts are respectively arranged on the left side and the right side of the trapezoidal support and are connected with a motor, a conveyor belt is connected onto the rotary shafts and the rollers, heat shrink tube support strips are uniformly distributed on the conveyor belt, two rows of harness ring clamp grooves are formed in the conveyor belt and are respectively close to the edges of two sides of the conveyor belt, the harness ring clamp grooves on each row are positioned on the same straight line, and a heat-insulation plate is fixed to the upper side of the trapezoidal support and is positioned on the lower surface of the conveyor belt. The efficient and energy-saving shrink machine has the advantages that the work efficiency can be improved by the aid of an assembly line form, the heating time and heating temperatures can be effectively controlled, and the high-requirement shrinking purpose can be achieved; the purpose of saving energy can be achieved by means of recycling hot air, workers can be separated from heating locations and can be protected against heating of the shrink tubes, irritation of other insulating gas and effects of the high temperatures, accordingly, the physical health of the workers can be protected, and occupational diseases can be reduced.
