Fixed-angle extrusion glass cement glue-flowing tube

Abstract

The invention relates to a glue gun accessory, in particular to a fixed-angle extrusion glass cement glue-flowing tube. The fixed-angle extrusion glass cement glue-flowing tube comprises a casing handle, a top shell, taped fins and a glue outlet, wherein the lower end of the casing handle is provided with the arc top shell which is integrated with the casing handle, the top shell and a positioning plate which is arranged below the top shell and is integrated with the casing handle commonly constitute the half-elliptic glue outlet of which the major axis of section is horizontal; the angle between the positioning plate and the axial lead of the casing handle is 20-45 degrees; and two taped fins which are integrated with the top shell are arranged on the two sides of the top shell and the taped fins are arc shells. The top shell and the taped fins of the invention can be used to extrude glass cement to form the adhesive tape with bowed section, thus further increasing the sealing effectof the glass cement to the joints of the curtain wall.

Description

technical field [0001] The invention relates to a glue gun accessory, in particular to a fixed-angle extrusion type glass glue outlet hose. Background technique [0002] Existing glass glue outlet hose has a structure of a tapered cylinder with a circular hole at the tip. In the process of using this glass glue outlet hose to glue the joints of the glass curtain wall, the strip glass glue extruded from the round hole has a circular cross section. The width is small, and the effective coverage area of ​​the joint is very small. At the same time, the bonding area of ​​the glass glue to the surface of the curtain wall on both sides of the joint is also very limited. This not only has a poor sealing effect, but also causes waste of glass glue. Some gluing workers also use their fingers to smooth the round strip of glass glue along the seam or make its cross section into a semicircle after gluing to increase the bonding area between the glass glue and the surface of the curtain...

AI Technical Summary

Problems solved by technology

In this way, not only the sealing effect is poor, but also the waste of glass glue is caused.

Some gluing workers also use their fingers to smooth the round strip of glass glue along the seam or make its cross section into a semicircle after gluing to increase the bonding area between the glass glue and the surface of the curtain wall. The operation is not only very cumbersome, but also has high technical requirements for the operator. In addition, it is very difficult to clean the glass glue on the fingers. At the same time, the glass glue on the fingers is easy to stick to the curtain wall during the operation, causing pollution.
