Embodiment 1

[0054] like figure 2 , 3 , 4 shows the stretch film welding equipment for the hanging film insulating glass provided by the present invention, wherein the structures of the hanging film insulating glass, the stretch film frame 4 and the elastic clip 3 are detailed in No. ZL201320644191.6 and Patent No. ZL201320644286.8.

[0055] The stretch film welding equipment includes: a positioning frame 100 to determine the working reference line, a film stretching mechanism 200 that sends out the film and stretches it and lays it horizontally on the stretch film edge of the stretch film frame, and connects two adjacent sides parallel to the film axis. The stretch film frame on the seam of the glass is welded at the same time and the film on this section is bidirectionally tensioned (referring to the direction of glass movement and perpendicular to the direction of glass movement). Rolling mechanism 400 that cuts off the excess film on both sides along the horizontal edge of the glass...

Abstract

The invention discloses stretched diaphragm welding equipment for suspension diaphragm hollow glass. The stretched diaphragm welding equipment comprises a positioning rack, a diaphragm tensioning mechanism, a bilateral welding mechanism, a trimming mechanism, a diaphragm cutting rack, an edge welding rack and a precisely positioning and alternatively moving workbench; especially the diaphragm tensioning mechanism, the bilateral welding mechanism, the trimming mechanism and three vacuum grasp mechanisms driven by three linear modules installed on the workbench form a tension control system together, and is synchronously controlled by a signal output by an encoder device for measuring the sendout of diaphragm rolls; welding points which are used for fixing a film on two adjacent frames of front glass and rear glass by the bilateral welding mechanism act as traction ends, so that uniform and continuous stretched diaphragm pretension is always kept in the processes of film feeding, welding and edge cutting as well as glass positioning, alterative moving and the like. According to the invention, the automatic continuous operation of stretched diaphragm welding is realized, and the stretched diaphragm welding equipment has uniform and controllable pretension.

Description

technical field [0001] The invention relates to the field of green energy-saving buildings, in particular to a stretch film welding process and equipment for film-suspended insulating glass. Background technique [0002] Energy-saving buildings have higher and higher requirements for the optical and thermal performance of insulating glass, and technologies such as adding a heat-insulating hollow layer, filling inert gas, and low-emissivity coatings have been widely used. The insulation glass with two or three hollow layers composed of plastic film suspended in the middle has a very good U value. If the low-radiation optical coating is used and the hollow layer is filled with inert gas, the U value can be lower than 0.56W / ㎡.K. [0003] Swiss technicians invented the inner suspension film technology (US Patent No. 5,237,787) that used springs as stretch film elements to fix the film on the frame around the glass through ultrasonic welding technology. The applicant invented ...
