Improved cold glue spraying system of KDF2 forming machine

Abstract

The invention discloses an improved cold glue spraying system of a KDF2 forming machine. The system comprises a glue tank, a valve and two cold glue nozzles; a glue outlet pipe is arranged at the bottom of the glue tank, the valve is arranged on the glue outlet pipe, and the system further comprises a double-flow gear pump; a glue inlet of the double-flow gear pump is connected with the glue outlet pipe, and the two cold glue nozzles are connected with one glue outlet of the double-flow gear pump through a hose; and on the basis of an original cold glue spraying system, the double-flow gear pump is added, glue in the glue tank passes through the double-flow gear pump firstly, and is pumped into the cold glue nozzles through the double-flow gear pump; and the magnitude of the glue amount is controlled through the double-flow gear pump and can be controlled to range from 5 g / min to 200 g / min. The double-flow gear pump is powered by a variable frequency motor, the variable frequency motor is connected to a host servo through a frequency changer, the speed of the variable frequency motor can be completely synchronous with the running speed of a machine, and therefore the glue flow can be precisely controlled, and the product quality requirement can be greatly improved.

Description

technical field [0001] The invention relates to a glue spraying system in smoke machine equipment, in particular to an improved cold glue spraying system of a KDF2 molding machine. Background technique [0002] see figure 1 , the current KDF2 forming machine cold glue spraying system adopts the self-flowing principle, and a glue tank 30 is placed about 50 cm above the two cold glue nozzles 10 and 20, and the cold glue nozzles 10 and 20 and the glue tank 30 are connected with two soft glue nozzles. Pipes 40, 50 are connected, and valves 60, 70 are installed in the middle. The flow size of glue is controlled by valve 60,70. In addition, as the amount of glue in the glue tank 30 is constantly changing, it will also have a certain impact on the flow of glue, so it is difficult to accurately control the flow of glue. Moreover, the flow of glue and the operating speed of the equipment cannot be synchronized, so that the amount of glue on the filter rod is not uniform, which aff...

In addition, as the amount of glue in the glue tank 30 is constantly changing, it will also have a certain impact on the flow of glue, so it is difficult to accurately control the flow of glue

Moreover, the flow of glue and the running speed of the equipment cannot be synchronized, so that the amount of glue on the filter rod is not uniform, which affects the product quality and increases the amount of glue used.
