Problems solved by technology

[0007] 1. Since the rubber cartridge will expand after being pressurized, the amount of glue ejected is affected by the fluctuation of air pressure, and it is difficult to accurately control the amount of glue ejected;
[0008] 2. The mixing ratio of the two glues is inaccurate, and the amount of glue spit and the mixing ratio cannot be quantified digitally;
[0009] 3. The dispensing device is bulky and inconvenient to disassemble and clean;
[0010] 4. The amount of glue spit is affected by the change of glue viscosity, and the glue with a viscosity of 10000CPS is even more difficult to control the amount of glue spit

Abstract

The invention relates to the technical field of automatic adhesive dispensing, in particular to a double-liquid adhesive-dispensing device which comprises a first screw rod valve assembly, a second screw rod valve assembly and a static mixing pipe. The first screw rod valve assembly comprises a first motor assembly, a first screw rod assembly and a first cavity assembly; the second screw rod valveassembly comprises a second motor assembly, a second screw rod assembly and a second cavity assembly; the first motor assembly and the second motor assembly are located above the first cavity assembly and the second cavity assembly; the first screw rod assembly and the second screw rod assembly are arranged in the first cavity assembly and the second cavity assembly, and are connected with the first motor assembly and the second motor assembly; and the first cavity assembly and the second cavity assembly are connected with the static mixing pipe and are connected with a first adhesive cylinder and a second adhesive cylinder. The double-liquid adhesive-dispensing device is compact in structure, small in shape and higher in adhesive output accuracy.

Description

technical field [0001] The present application relates to the technical field of automatic dispensing, in particular to a double-liquid dispensing device. Background technique [0002] In the prior art, two-component glue dispensing methods usually include the following three types: [0003] 1. Push the piston rod to move by controlling the compressed air on and off, so as to press the glue out of the glue tube; [0004] 2. Drive the piston rod to move linearly through the motor + screw rod, so as to press the glue out of the rubber tube; [0005] 3. Extrude the glue through the manual glue gun. [0006] The above three two-component glue dispensing methods have the following disadvantages: [0007] 1. Since the rubber cartridge will expand after being pressurized, the amount of glue ejected is affected by the fluctuation of air pressure, and it is difficult to accurately control the amount of glue ejected; [0008] 2. The mixing ratio of the two glues is inaccurate, and...
