Glue injection device for insulating glass molecular sieve filling machine

Abstract

The invention relates to a glue injection device, in particular to a glue injection device for an insulating glass molecular sieve can filling machine, which belongs to glass processing machinery. The glue injection device comprises a hot die support, a hot die, a side baffle plate, a connector, a cover plate, a flat plate, a glue barrel, a pull rod, a clamping plate, a glue barrel seat, an air cylinder support, a connecting plate, an inclined connecting plate, an air cylinder ejector rod, an air cylinder, a resistance wire and a thermocouple sensor; the heating resistance wire and the thermocouple sensor are additionally arranged in the hot die and a PLC is applied to control temperature of glue blocking, the control accuracy achieve 0.1 DEG C, and the glue plugging quality is effectively improved; two glue sleeves are installed in the hot die, the glue flows out from the glue sleeves during the glue plugging process and does not directly flow out from the hot die, and the glue sleeves are connected with the hot die through keys, thus being convenient to assembly and the disassembly and being beneficial to removal of the residue glue; and a glue pushing device adopts an air cylinder for pushing glue, thereby being beneficial to control on the glue pushing pressure and avoiding excessively high or small glue pushing pressure.

Description

technical field [0001] The invention relates to a glue injection device, in particular to a glue injection device for a hollow glass molecular sieve can filling machine belonging to glass processing machinery. Background technique [0002] Insulating glass has excellent thermal insulation performance, and can reduce cold radiation, reduce noise, and prevent condensation. It is currently the building door and window with the most significant energy-saving effect. Since the 1950s, it has developed very rapidly and has been widely used in economically developed countries. In addition to being used in the construction industry, insulating glass is also used in industrial sectors such as the vehicle and ship industry, refrigerator and freezer manufacturing. With the development of the economy, especially the increasing awareness of environmental protection and energy conservation, the country has higher and higher requirements for environmental protection, energy conservation, a...

Problems solved by technology

In the production of hollow glass, molecular sieve filling machines or manual filling methods are generally used to fill aluminum strip spacer frames. The glue injection device is an important device in the molecular sieve filling machine. After the frame is filled with molecular sieve, butyl glue is used to inject glue into the filling hole; however, the current disadvantages of the glue injection system of the existing molecular sieve filling machine are: 1. The glue filling temperature is uncontrollable, resulting in low quality of glue blocking and affecting the sealing Second, it is difficult to clean the remaining glue in the glue feeding channel, which affects the quality of glue filling; Third, the original mechanical push glue device is more than rigid and not flexible enough
