Door and window sealing strip whole window welding machine

Abstract

The invention discloses a whole window welding machine for door and window sealing strips. The split mold cavity is fixedly installed on the working table, the PE coil installation roller is located at the lower part of the chassis, and the PE coil pulling device includes a film pulling cylinder vertically fixed on the upper part of the vertical frame and a film pulling cylinder installed on the upper part of the vertical frame. The manipulator at the lower end of the piston rod, the manipulator is located just above the middle of the split mold cavity, the cutting device and the IR heating device are horizontally installed in the middle of the vertical frame, and the cutting device is located below the IR heating device. The mold cavity is used as the positioning device for the two angle sealing strips to be connected, and the PE coil is used as the welding material. After heating the corner end of the sealing strip and the PE coil to the welding temperature, the two sets of clamping mechanisms are pushed to face each other by controlling the clamping cylinder. Movement, simple operation and high degree of automation.

Description

technical field [0001] The invention relates to the technical field of sealing strip connection methods, in particular to a window welding machine for door and window sealing strips. Background technique [0002] In recent years, affected by the national building energy-saving policy and the energy crisis, the proportion of energy-saving and environmentally-friendly doors and windows has gradually increased. Sealant strips occupy an important proportion in high-quality doors and windows. [0003] The current methods of jointing corners of sealant strips in the door and window industry are: [0004] 1. Glue bonding; 2. Molded corner glue bonding; 3. Injection corner welding; 4. Rubber sheet vulcanization welding. Although the above methods can achieve the purpose of joining corners, there are also problems of varying degrees: [0005] Glue bonding: the bonding part is easy to harden and loses the original elasticity of the rubber strip, and the bonding part will crack due t...

AI Technical Summary

Problems solved by technology

[0005] Glue bonding: the bonding part is easy to harden and loses the original elasticity of the rubber strip, and the bonding part will crack due to the influence of the use environment, making it in appearance, airtight, watertight, sound insulation and noise prevention, dustproof, energy saving, etc. Lose original performance;

[0006] Injection corner welding, vulcanization and bonding of rubber sheets: At present, it is difficult for door and window companies to achieve continuous production due to cross-industry factors; and this process has low production efficiency and high production costs

[0007] The corner bonding process currently in use has the following problems: the closure is not in place, the window pops and there are gaps; the watertightness, airtightness, and sound insulation are poor; the glue strips at the corners of the entire window have cracks; water leakage and dust accumulation at the corners; The overall aesthetic effect is poor; the production cost is high; the continuous production is poor, etc.
